DETAILED DESCRIPTION OF THE EMBODIMENTS
(17) FIG. 1 is a schematic structural view of a sliding carpet according to an embodiment of the present application. The sliding carpet of the present application includes multiple roll shaft units. Each roll shaft unit includes a roll shaft 310, and a fixing catch 210 which is in contact with and connected to one side of the roll shaft 310. The fixing catch 210 includes a supporting body. The supporting body is provided with a first through hole 213 and a second through hole 214. The axes of the first through hole 213 and the second through hole 214 are perpendicular to each other and do not intersect with each other. Moreover, the sliding carpet assembly further includes multiple connecting ropes 100. In a first direction, the connecting ropes 100 pass through the first through holes 213 to connect the multiple sequentially arranged roll shaft units in series. In a second direction perpendicular to the first direction, the connecting ropes pass through the second through holes 214 to sequentially connect the multiple sequentially arranged fixing catches 210. Thus, the multiple roll shaft units are connected in series, and then the roll shaft units connected in series are rejoined into a surface to constitute the sliding carpet assembly. When a person or a heavy object passes through the sliding carpet assembly, rolling friction occurs instead of sliding friction. The person can continue sliding thereon after exercise. This avoids falling due to inertia, impact injury caused by excessive resistance, or injury to the human body or other objects due to excessive friction. Meanwhile, the roll shaft 310 can only slide in a fixed direction, limiting the direction of movement and avoiding side-to-side sway. The sportsman can continue sliding through the surface of the sliding carpet, slow down and stop, and will not suddenly stop moving due to excessive friction. Or, when a moving object slides through the sliding carpet assembly, the direction of object movement is limited, which increases the safety. The center shaft 410 is sleeved in the roll shaft 310. The center shaft 410 is a circular tube that is sleeved in the roll shaft 310. The specific structure of the center shaft 410 refers to a cross-sectional view of a center shaft of FIG. 9 and a three-dimensional view of a center shaft of FIG. 10. When the roll shaft 310 rotates, the center shaft 410 can protect the connecting rope 100. Meanwhile, the roll shaft 310 and the center shaft 410 are sleeved with each other to further enhance the sealing properties of the sliding carpet assembly and prevent invasion of foreign matters. The center shaft 410 also has the function of supporting the roll shaft 310, thereby ensuring that the roll shaft 310 is not squeezed and stops rotating, and ensuring that the roll shaft 310 can be freely rotated.
(18) FIG. 2 is a three-dimensional view of the fixing catch 210 of the present application. In the above sliding carpet assembly, the first through hole 213 and the second through hole 214 are further provided with a first connecting portion 211 and a second connecting portion 212 which extend outwards along an axial direction of the first through hole. A first end 321 (as shown in FIGS. 7 and 8) of the roll shaft 310 is in sleeved connection with the second connecting portion 212. A second end 322 (as shown in FIGS. 7 and 8) of the roll shaft 310 is in sleeved connection with the first connecting portion 211 of the next adjacent fixing catch 210. The connecting portion is designed such that the fixing catch 210 and the roll shaft 310 body are sleeved. When the sliding carpet assembly is deformed by an external force, the first connecting portion 211, the center shaft 410 and the second connecting portion 212 are on the same straight line, and support the rotation of the roll shaft 310, so that the roll shaft 310 will not be squeezed and can be rotated normally. Moreover, such a sleeved connection is tight, preventing foreign matters from entering gaps of the sliding carpet assembly and protecting the sliding carpet assembly, so that the sliding is smoother.
(19) FIG. 3 is a side view of the fixing catch in FIG. 2. It can be seen from the figure that the fixing catch 210 is a block structure, the upper surface is arcuate, or the fixing catch 210 has a wedge-shaped end (as shown in FIG. 4), where the wedge has a wide upper part and a narrow lower part, and B is 3. In other embodiments, the fixing catch may also be square, the sliding carpet assembly is subjected to great pressure during the application process, and the block shape can increase the contact surface with the support surface, reduce the pressure, achieve a supporting function, have stability, increase pressure bearing, increase load bearing, and can provide the movement of goods. One function of the fixing catch 210 is to define the position of the roll shaft 310 by defining the positions of the connecting ropes in the first direction and the second direction, so that the sliding carpet assembly is stabilized into a plane that can conform to the shape, and can be laid into a plane, a slope or a curved surface. The arc shape of the upper surface of the fixing catch 210 is to reduce the contact area of the surface. As the contact area is reduced, the friction of the surface is small, so that the sliding is smoother. To make the structure of the fixing catch 210 more convenient to those skilled in the art, FIG. 5 is a top view of the fixing catch 210, and FIG. 6 is a front view of the fixing catch 210.
(20) FIG. 7 is a cross-sectional view of the roll shaft 310 of the sliding carpet assembly as shown in FIG. 1. The middle of the roll shaft 310 is a constant diameter cylindrical hole. Both ends of the constant diameter cylindrical hole are in communication with a tapered hole having an inner diameter gradually increasing. There is LA in the cross-sectional view of the tapered hole, and after repeated experiments, A is 15. If being greater than this angle, a gap between the roll shaft 310 and the fixing catch 210 is too large, and it is prone to invaded by foreign matters, affecting the rotation of the roll shaft 310. If being smaller than this angle, the sliding carpet assembly is deformed by an external force, the roll shaft 310 and the fixing catch 210 are too tight, causing a jam and affecting the rotation. The annular grooves 311 surround the outer surface of the roll shaft 310. The two annular grooves 311 divide the outer surface of the roll shaft 310 into three regions. The annular grooves 311 increase the frictional force in the first direction, and define the second direction as the sliding direction, so that the human body or the object slides to the second direction perpendicular to the first direction. FIG. 8 is a three-dimensional view of the roll shaft 310, in which the structure of the annular groove 311 is clearer.
(21) FIG. 8B is a schematic view of a roll shaft in one embodiment, where the roll shaft 310 is a hollow cylinder and the outer surface is a curved surface. Both ends of the cylinder are a first end 321 and a second end 32, respectively. The roll shaft 210 of the present embodiment may be applied to other embodiments.
(22) FIG. 11 is a schematic structural view of an embodiment of a gliding carpet in a specific embodiment. FIG. 12 is a side view of a sliding carpet according to an embodiment of the sliding carpet of the present application. The present application provides such a sliding carpet. The above sliding carpet assembly is suspended over a bracket by a spring suspension assembly or suspended according to the needs of the application. The spring suspension assembly includes a first suspension assembly and a second suspension assembly. The first suspension assembly is perpendicular to the second suspension assembly. The first suspension assembly includes a tension spring 510, a first connecting plate 523, a first clamping sleeve 520, and a push spring 521. The tension spring 510 includes a first pull hook 511 and a second pull hook 512, the first pull hook 511 and the second pull hook 512 being located at both ends of the tension spring 510. The first connecting plate 523 includes a first hole and a second hole, the first pull hook 511 hooks the first hole of the first connecting plate 523, and the connecting rope passes through the second hole to form a closed circle. The first clamping sleeve 520 is located between the connecting plate and the push spring. The first clamping sleeve 520 is sleeved at one end of the connecting rope in the first direction. The second suspension assembly includes a second connecting plate 532 and a second clamping sleeve 531. One end of the second clamping sleeve 531 is in contact with and connected to the second connecting plate 532, and the other end is in contact with and connected to the outer side of the second through hole 214 of the fixing catch 210. The second clamping sleeve 531 is sleeved at one end of the connecting rope perpendicular to the first direction. When the sliding carpet is deformed by an external force, deformation occurs, and the push springs 521 are stretched or contracted by an external force to act as a buffering function, so that the roll shafts 310 are tightly closed. The first clamping sleeve 520 realizes a tight connection between the connecting rope and the first connecting plate 523. The second clamping sleeve 531 realizes a tight connection between the connecting rope and the second connecting plate 532. The second pull hook can be hooked to a certain object or bracket as needed, thus increasing the application environment. The size and shape of the sliding carpet can be changed as required, which increases the practicality of the sliding carpet. Meanwhile, the sliding carpet does not need to consume electricity and water, thereby saving energy. A person does not need to pay attention to the sliding carpet for a long time, thereby saving manpower. If there is a problem with a roll shaft or other parts, only some of the components need to be replaced, thereby prolonging the life cycle and the service life. The positional relationship between the roll shaft 310 and the fixing catch 210 and the first suspension assembly of the sliding carpet in FIG. 12 is clearer.
(23) FIG. 13 shows a schematic structural view of a sliding carpet according to an embodiment of the present application. The elastic suspension assembly is composed of a tension spring 510. In the first direction, the connecting rope 100 passes through the first through hole 213 of the fixing catch 210 to connect the multiple sequentially arranged roll shaft units in series. In the second direction perpendicular to the first direction, the connecting rope passes through the second through hole 214 to sequentially connect the multiple sequentially arranged fixing catches 210. The roll shaft unit includes the roll shafts 310 and the fixing catches 210. Thus, the multiple roll shaft units are connected in series, and then the roll shaft units connected in series are rejoined into a surface to constitute the sliding carpet assembly. One end of the tension spring 510 is connected to the fixing catch 210 of the sliding carpet assembly, and the other end is connected to a fixing frame, where the fixing frame may be a frame or other fixtures prepared in advance. In this way, the sliding carpet can be fixed. When the sportsman falls on the sliding carpet, the sliding carpet can catch the sportsman and assist the sportsman to complete the action. Moreover, the rope 100 of the sliding carpet of the present application may be an elastic rope. When an athlete falls on the sliding carpet, the sliding carpet may be deformed after contacting the sliding carpet, and the elastic rope 100 may ensure that the sliding carpet can be deformed at the time of deformation.
(24) FIG. 14 shows a schematic structural view of a sliding carpet according to an embodiment of the present application. The sliding carpet assembly is directly fixed to a fixing frame or other fixtures for assisting in transporting heavy objects. In the present embodiment, the rope 100 is a rigid material that is not easily deformed. As a weight moves over the sliding carpet, the roll shaft 310 slides, reducing the force required to transport the weight. The rigid rope 100 keeps the sliding carpet flat and makes the weight easier to move. The manner of connecting the roll shaft 310 and the fixing catch 210 to the center shaft 410 is as described above, and will not be described herein.
(25) In another specific embodiment, the present application provides a sliding carpet that uses the sliding carpet assembly of the present application. The sliding carpet is directly laid on an upper surface of a slide body, where the upper surface of the slide body is a plane or a curved surface. For example, the U-shaped slideway is a common slideway for skiing, skateboarding, etc. The sliding carpet of the present application is laid on the upper surface of the U-shaped slideway. A rolling friction is formed on the surface of the sliding carpet when a person slides from the bottom of the U-shaped slideway to the top of the U-shaped slideway. The friction is reduced, making the sliding easier. The entire action is smooth, while the sliding direction of the sliding carpet is uniform, and there is no deviation from the slideway, which is safer. The sliding carpet is directly laid on the surface of objects such as runways, floors, slides or slopes for sports training, entertainment or transporting heavy objects, etc. The sliding carpet produces rolling friction through objects or people on the surface, rather than sliding friction, making the movement smoother. If transporting goods, the resistance is reduced, and time and effort are saved. The sliding friction generates a large amount of heat, and the rolling friction of the sliding carpet generates less heat, which does not cause excessive friction and high temperature to injure the human body or cargoes. The sliding carpet is convenient to install and easy to manage, does not consume water and electricity, and achieves energy saving and environmental protection. Meanwhile, it can be laid according to the terrain and has strong practicability.
(26) The above is only a preferred specific implementation manner of the present application, but the scope of protection of the present application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical scope disclosed in the present application, which should be covered by the scope of protection of the present application. Therefore, the scope of protection of the present application should be determined by the scope of the claims.
