EMBODIMENTS

(9) The present invention will be further detailed below in combination with the accompanying drawings and the specific embodiments.

(10) As shown in FIGS. 1 to 6, an embodiment of the present invention provides an easily-assembled desk foot, which is connected at a lower end of a lifting column of a height-adjustable desk or at a bottom of another office desk, shelf or display screen bracket to achieve a support effect as a base. In this embodiment, the desk foot structurally comprises a desk foot body 1, which is internally hollow and provided with insertion openings 100 at both ends. A connection hole 101 for connecting the lower end of the lifting column 4 is disposed on the desk foot body 1. The desk foot body 1 is formed integrally by cutting a square metal pipe, and both end surfaces of the desk foot body 1 are vertical planes. In other embodiments, the desk foot body 1 may also be formed by cutting a metal circular pipe, a metal polygonal pipe or a metal elliptical pipe or the like. Two end cover assemblies 2 are disposed at both ends of the desk foot body 1, and have insertion portions 200 matched with the insertion openings 100 at both ends of the desk foot body 1 respectively. The bottom of the insertion portion 200 is connected with a support portion 201 protruding downwardly and extending along a length direction of the insertion portion 200. When the insertion portion 200 of the end cover assembly 2 is inserted into the insertion opening 100, the support portion 201 is supported at the bottom of the desk foot body 1. In the present embodiment, the insertion portion 200 and the support portion 201 are integrally formed. Specifically, the insertion portion 200 and the support portion 201 are a plastic integrally-injection-molded structure, and the insertion portion 200 and the support portion 201 are hollow structures with openings disposed at their inner ends.

(11) The insertion portion 200 of the desk foot is equivalent to the pipe plug at both ends of the desk foot body 1, the support portion 201 is equivalent to the foot pad at the bottom of the desk foot body 1, and the insertion portion 200 and the support portion 201 are integrally formed, that is, the end cover assembly 2 formed by the insertion portion 200 and the support portion 201 is an integral structure. The end cover assembly 2 can be processed in only one mold with simpler production procedure and lower production costs. Further, when the end cover assemblies 2 are assembled, it is only required to insert the insertion portions 200 into respective insertion openings 100 of both ends of the desk foot body 1. Therefore, the mounting process can be easily and conveniently completed without any hand tools or any fixing screws or the like. The integrally-formed end cover assembly 2 has good structural stability. Moreover, when the insertion portion 200 is inserted into the insertion opening 100, the support portion 201 is supported at the bottom of the desk foot body 1, that is, the top of the support portion 201 is closely attached to the bottom of the desk foot body 1. In this way, a contact area between the support portion 201 and the desk foot body 1 can be increased to achieve better support effect for the desk foot body 1 and avoid occurrence of shake.

(12) By referring to the FIGS. 4 to 5 again, in an embodiment of the present invention, an insertion groove 202 for inserting a bottom wall 102 of the desk foot body 1 is disposed between the insertion portion 200 and the support portion 201, and the bottom wall 102 of the desk foot body 1 is inserted into the insertion groove 202 to enable the top of the support portion 201 and the bottom of the desk foot body 1 to be mutually attached. Specifically, a connection portion 206 extending along the length direction of the insertion portion 200 is disposed between the insertion portion 200 and the support portion 201, two insertion grooves 202 are formed by using two outer sidewalls of the connection portion 206, the bottom wall 102 of the insertion portion 200 and a top wall of the support portion 201, and an avoiding hole 103 for inserting the connection portion 206 when the insertion portion 200 is inserted into the insertion opening 100 is disposed on the bottom wall 102 of the desk foot body 1. The connection structure between the end cover assembly 2 and the desk foot body 1 is made more stable and sturdier. In addition, the disposals of the avoiding hole and the hollow structures of the insertion portion 200 and the support portion 201 can make the desk foot lighter and help move and mount it more easily and simply. In this embodiment, the insertion grooves 202 formed on the end cover assembly 2 are two insertion grooves symmetrical about the connection portion 206 left and right. In other embodiments, there may be one or three or more insertion grooves 202. In this embodiment, a radially-convex end cap 203 is disposed at an outer end of the insertion portion 200; when the insertion portion 200 is inserted into the insertion opening 100, an outer sidewall of the end cap 203 is flushed with an outer sidewall of the desk foot body 1. In this case, after the end cover assemblies 2 are inserted into the desk foot body 1, both ends of the desk foot body 1 will be smoother and more integral.

(13) By referring to FIG. 5 again, in an embodiment of the present invention, a plurality of outwardly-protruding strips 204 distributed along a circumference of the insertion portion 200 and extending along the length direction of the insertion portion 200 are disposed on an outer sidewall of the insertion portion 200, and the outer sidewalls of the insertion ends of the protruding strips 204 are disposed as outer-thin and inner-thick inclined surfaces 205. The disposal of the protruding strips 204 increases the mechanical strength of the insertion portion 200, and the disposal of the inclined surface 205 of the insertion end of the protruding strip 204 facilitates insertion of the end cover assembly 2 into the insertion opening 100 of the desk foot body 1. In this embodiment, a cross section of the insertion portion 200 is quadrilateral and thus protruding strips 204 are distributed on the top, bottom, and two sides of the insertion portion 200. In other embodiments, the cross section of the insertion portion 200 may also be circular or elliptical or the like, and at this time, a plurality of protruding strips 204 may be distributed along the circumference of the outer sidewall of the insertion portion 200.

(14) As shown in FIG. 7, another embodiment of the present invention provides a height-adjustable desk, which structurally comprises a desk board 3, a desk foot, a lifting column 4 connecting the desk board 3 and the desk foot, and a drive motor for driving the lifting column to lift. The desk foot of the height-adjustable desk may be the desk foot according to any one of the above embodiments. The connection operation between the end cover assembly 2 of the desk foot of the height-adjustable desk and the desk foot body 1 can be carried out easily and conveniently without any hand tools; the connection structure between the end cover assembly 2 and the desk foot body 1 is more stable and sturdier, and the desk foot can be manufactured in a simple process with lower costs.

(15) The above descriptions are merely the specific embodiments of the present invention but the scope of protection of the present invention is not limited hereto. Any changes or substitutions easily thought of by those skilled in the art within the technical scope of the present invention shall fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention is indicated by the claims.
