DETAILED DESCRIPTION

(8) The present invention will be further described below in conjunction with FIG. 1 to FIG. 5 and specific implementations.

(9) As illustrated in FIG. 1 to FIG. 4, an anti-noise spring seat includes a seat board 1 and an underframe 2 detachably connected with the seat board 1, a plurality of springs 3 are arranged between the seat board 1 and the underframe 2, wherein the top of the underframe 2 is provided with a plurality of first seating grooves 41 in which first mounting holes 42 are formed, the bottom of the seat board 1 is provided with a plurality of second seating grooves 51 corresponding to the first seating grooves 41, second mounting holes 52 are formed in the plurality of second seating grooves 51, first gaskets 43 for cancelling noise are arranged in the first seating grooves 41, second gaskets 53 for cancelling noise are arranged in the second seating grooves 52, one ends of the springs 3 are abutted against the first gaskets 43, and the other ends of the springs 3 are abutted against the second gaskets 53.

(10) The seat board 1 and the underframe 2 of the present invention are made of wood, and bolts and the springs 3 which are used for connecting the seat board 1 and the underframe 2 are made of iron, the two materials can touch each other during use to cause noise of collision and friction. In this embodiment, when the spring chair is assembled, the second gaskets 53 are placed in the second seating grooves 51 of the seat board 1 firstly, the first gaskets 43 are placed in the first seating grooves 41 of the underframe 2, then the springs 3 are placed, one ends of the springs 3 are abutted against the first gaskets 43, the other ends of the springs 3 are abutted against the second gaskets 53, then the bolts are mounted, the bolts penetrate from the first mounting holes 42, then successively penetrate through the first gaskets 43, the springs 3 and the second gaskets 53 and finally penetrate into the second mounting holes 52, the first mounting holes 42 are through holes, the second mounting holes 52 are blind holes and are provided with internal threads, and the bolts are in threaded connection with the second mounting holes 52 to realize the fixed connection of the seat board 1 and the underframe 2.

(11) The first gaskets 43 and the second gaskets 53 function to effectively buffer the collision of wood and iron so as to reduce noise of collision and friction due to touch in the process of using the two materials, so that the present invention can effectively solve the problem that noise is generated when the spring chair is used; the two ends of the springs 3 are respectively seated in the first seating grooves 41 and the second seating grooves 51 without displacement, so that the anti-noise spring chair provided by the present invention is firm in structure; and according to the present invention, the bolts are adopted to fix the seat board 1 and the underframe 2, so disassembling and assembling are convenient.

(12) A user of the anti-noise spring chair can seat on the seat board 1, and shakes front and back, up and down, and left and right to relieve the fatigue of vertebral column.

(13) The anti-noise spring chair can be carried in a detachable and splitting manner, so logistics fees are reduced.

(14) In this embodiment, the underframe 2 includes two crossed support rods 21 of which the two ends are provided with the plurality of first seating grooves 41, when assembling of the seat board 1 and the underframe 2 are performed, the positions of the first seating grooves 41 can be determined depending on the weight of the user, the first seating grooves 41 can bear the weights of different people if being matched with the springs 3 having different thickness and height standards, the first seating groove 41 which is more closer to the center position of the seat board 1 can bear smaller weight, instead, the first seating groove 41 which is more far away from the center position of the seat board 1 can bear bigger weight. As illustrated in FIG. 2, if the weight of the user ranges from 20 kg to 80 kg, the first seating groove 41 close to the inside can be selected to perform assembling; if the weight of the user ranges from 40 kg to 100 kg, the first seating groove 41 located in the middle can be selected to perform assembling; and if the weight of the user ranges from 60 kg to 200 kg, the first seating groove 41 located at the outside can be selected to perform assembling.

(15) In this embodiment, the cross bars 22 are arranged between the two support rods 21 to enhance the strength of the underframe 2 so that the underframe 2 can bear a heavier user.

(16) In this embodiment, the center of the top of the underframe 2 is provided with a third seating groove 61 in which a third mounting hole 62 is formed, the bottom of the seat board 1 is provided with a fourth seating groove 71 corresponding to the third seating groove 61, a fourth mounting hole 72 is formed in the fourth seating groove 71, a third anti-noise gasket 63 is arranged in the third seating groove 61, a fourth anti-noise gasket 73 is arranged in the fourth seating groove 71, one end of the spring 3 is abutted against the third anti-noise gasket 63, and the other end of the spring 3 is abutted against the fourth anti-noise gasket 73. In the present invention, four springs for connecting the seat board 1 with the underframe 2 are distributed on four corners of the seat board 1, when the user seats on the spring chair and shakes at random, the spring on one of corners bears a force, in this way, it is easy to damage a connection structure of one of the springs and the seat board 1 as well as the underframe 2, and thus, a spring structure is additionally arranged in the middle of the seat board 1 and in the middle of the underframe 2, when in design, the length of the spring 3 in the middle is slightly longer than the lengths of the springs 3 on the four corners, when the user seats, the spring structure in the middle firstly bears the force, and then the spring structures on the four corners bear forces, so as to balance the forces of the four corners, thereby prolonging the service life of the spring chair.

(17) When the user seats on the seat board 1, the seat board 1 overcomes resistance generated by deformation of the springs 3 to be pressed downwardly, the bolts move downwardly along with the seat board 1, the bolts generate friction with the spring wires of the springs 3 when moving downwardly, hence, in this embodiment, the cross sections of the spring wires of the spring 3 are circular, and a friction force is reduced.

(18) The heads of the bolts adopted by the present invention are of spherical shapes, which is intended to prevent the anti-noise gasket from being damaged when moving; it is only when penetrating into the end parts of the second mounting holes 52 that the rod parts of the bolts are provided with external threads, the surfaces of the other positions of the rod parts are smooth surfaces so as to reduce friction forces generated between the rod parts and the spring wires of the springs 3 and noise generated by friction.

(19) There are certain gaps between the bolts and the underframe 2, so that when the user shakes the spring chair back and forth, the bolts cannot touch the inner wall of the underframe 2.

(20) As illustrated in FIG. 5, in this embodiment, the outsides of the springs 3 are sleeved with protection dome covers 8 which are made of sponge and have the following uses: 1, the springs 3 are protected to prevent the springs 3 from adhering dust or water to cause rustiness; and 2, when the chair is used, the springs stretch and generate friction with the protection dome covers 8 but noise does not occur.

(21) The above descriptions are merely preferred embodiments of the present invention, for those skilled in the art, variations of specific implementations and application scopes are made according to the spirit of the present invention, this specification should not be construed as limit of the present invention.
