[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] The terms "first" and "second" in this utility model are used for descriptive purposes only and should not be construed as indicating or implying relative importance, nor as a restriction on the order of events.

[0019] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] Please refer to the figure. A preferred embodiment of this utility model provides a table, which includes legs 400, a tabletop 300, a tabletop frame 200, and a quick-assembly mechanism 100. The tabletop frame 200 is fixed below the tabletop 300 to support it. The legs 400 support the tabletop 300 and the tabletop frame 200. The legs 400 and the tabletop frame 200 are detachably connected via the quick-assembly mechanism 100 to enable quick assembly and disassembly, facilitating user use.

[0021] As a preferred option, the support leg 400 can be a height-adjustable support leg 400, that is, the table is a height-adjustable table.

[0022] Combination Figure 1 and Figure 2 As shown, the table quick-assembly mechanism 100 includes a female connector 1, a male connector 2, a limiting member 3, a rotating rod 4, and a locking member 5. The male connector 2 is installed on the top of the support leg 400, and the female connector 1 and the limiting member 3 are both installed on the table frame 200. The female connector 1 and the male connector 2 are inserted into each other and are inserted into place in the horizontal direction X. The rotating rod 4 and the locking member 5 are used to cooperate with the limiting member 3 to lock the female connector 1 and the male connector 2 in the inserted state.

[0023] Understandably, the horizontal X and vertical Y directions referred to in this utility model are two mutually perpendicular directions in the horizontal direction, and the vertical Z direction is the height direction.

[0024] The locking element 5 is located at one end of the rotating rod 4, and the other end of the rotating rod 4 is rotatably connected to the connecting male seat 2, so that the locking element 5 can move closer to or away from the limiting element 3.

[0025] When the male connector 2 and the female connector 1 are inserted into each other, and the rotating rod 4 rotates relative to the female connector 1 so that the locking member 5 is located at the limiting member 3, the locking member 5 and the limiting member 3 are detachably connected, and the male connector 2 and the female connector 1 are locked in the insertion state.

[0026] When assembling the support leg 400 and the table frame 200, the male connector 2 at the top of the support leg 400 is inserted into the female connector 1 on the table frame 200. The rotating rod 4 is rotated so that the locking part 5 at one end moves to the limiting part 3. The locking part 5 is connected to the limiting part 3, which locks the male connector 2 and the female connector 1 into the inserted state. The connection is convenient and quick, and it can realize the rapid assembly between the support leg 400 and the table frame 200, which is convenient for users to assemble and use.

[0027] In this embodiment, as Figure 4 As shown, a guide groove 11 is provided on the connecting female seat 1. The guide groove 11 is L-shaped, and its longitudinal Y side is open. The guide groove 11 includes an insertion groove 111 and a positioning groove 112. The positioning groove 112 is arranged along the transverse X side, one end of which is closed and the other end is connected to the vertical Z end of the insertion groove 111. The other vertical Z end of the insertion groove 111 forms an insertion port 113.

[0028] like Figure 5 As shown, a guide block 21 is provided on the longitudinal Y-side of the male connector 2. The guide block 21 can enter the positioning groove 112 from the insertion port 113 through the insertion groove 111. The cooperation between the guide block 21 and the guide groove 11 enables the insertion and engagement between the male connector 2 and the female connector 1. When the guide block 21 moves along the transverse X-direction in the positioning groove 112 and abuts against the closed end of the positioning groove 112, the male connector 2 and the female connector 1 are inserted into place in the transverse X-direction.

[0029] Furthermore, combined with Figure 3 , Figure 6 and Figure 7 As shown, there are two female connectors 1, arranged along the longitudinal direction Y. Guide blocks 21 are provided on both sides of the longitudinal direction Y of the male connector 2. By using two female connectors 1, the reliability and stability of the connection between the male connector 2 and the female connector 1 can be guaranteed.

[0030] The male connector 2 is provided with a protrusion 22 on its longitudinal Y side, and the female connector 1 is provided with a groove 12. The groove 12 has a pressing wall 121. In the longitudinal Y direction, the pressing wall 121 is inclined toward the protrusion 22 so as to squeeze the protrusion 22 when the guide block 21 moves toward the closed end of the positioning groove 112, thereby making the connection between the male connector 2 and the female connector 1 tighter and improving the connection reliability.

[0031] In this embodiment, combined with Figure 4As shown, each female connector 1 is provided with two guide grooves 11, and a recess 12 is located between the two guide grooves 11. Correspondingly, each side of the male connector 2 in the longitudinal Y direction is provided with two guide blocks 21, which further improves the connection reliability between the male connector 2 and the female connector 1, and reduces the movement distance of the guide blocks 21 in the transverse X direction when inserted into the guide grooves 11, thus improving installation convenience; by utilizing the cooperation of four guide blocks 21 and guide grooves 11, the force points can be distributed to ensure uniform force distribution. The number of guide grooves 11 and guide blocks 21 is not limited to two, and can also be more than two.

[0032] like Figure 5 As shown, the male connector 2 has a hinge seat 23. The other end of the rotating rod 4 is connected to the hinge seat 23 via a rotating shaft. The hinge seat 23 facilitates the rotational connection between the male connector 2 and the rotating rod 4. The rotating rod 4 and the hinge seat 23 can be connected as a single unit. By installing the hinge seat 23 onto the male connector 2 using screws, welding, or other methods, a rotational fit between the rotating rod 4 and the male connector 2 can be achieved.

[0033] In this embodiment, as Figure 5 and Figure 6 As shown, the locking component 5 includes a cam 51 and a wrench 52, one end of which is fixedly connected to the cam 51. The cam 51 is rotatably mounted at one end of the rotating rod 4, and its rotation axis is perpendicular to the axis of the rotating rod 4. A limiting plate 31 is provided on the limiting component 3, and a clearance groove 30 is provided on the limiting plate 31. When the locking component 5 is located at the limiting component 3, the rotating rod 4 is located at the clearance groove 30, and the limiting plate 31 is located between the locking component 5 and the connecting male seat 2. When the locking component 5 rotates relative to the rotating rod 4, causing the protrusion of the cam 51 to apply force toward the limiting plate 31, the connecting male seat 2 and the connecting female seat 1 are locked in the insertion state.

[0034] During assembly, first, place the tabletop 300 face down on the ground, with the tabletop frame 200 facing up to expose the connecting female 1. With the top of the support leg 400 facing down, insert the connecting male 2 into the connecting female 1. Figure 5 As shown, this causes the guide block 21 to enter the guide groove 11 and move to the closed end of the positioning groove 112. Figure 7 As shown, then rotate the rotating rod 4 to move the locking member 5 to the limiting member 3, as shown. Figure 3 As shown, the locking member 5 is rotated so that the convex part of the cam 51 applies force to the limiting plate 31. Through the force between the cam 51 and the limiting plate 31, the locking member 5 can be locked in a position close to the limiting member 3, so that the locking member 5 is connected to the limiting member 3. At the same time, the rotating rod 4 can apply force to the connecting male seat 2, so that the connecting male seat 2 and the connecting female seat 1 can be reliably inserted and locked in the inserted state. The operation is convenient and greatly reduces the assembly difficulty for users.

[0035] Disassembly can be performed by reversing the operation. For example... Figure 7 As shown, rotating the locking member 5 causes the convex part of the cam 51 to release the force on the limiting plate 31, thus disengaging the locking member 5 from the limiting member 3; as Figure 6 As shown, rotate the rotating rod 4 to move the locking member 5 away from the limiting member 3; at this time, the plugging state between the connecting female 1 and the connecting male 2 is unlocked, and the two can move relative to each other, thereby separating and disassembling, which greatly reduces the difficulty of disassembly for users.

[0036] In this embodiment, combined with Figure 3 As shown, the limiting member 3 is located on one side of the connecting female seat 1 in the transverse X direction. When the locking member 5 is located at the limiting member 3, the limiting plate 31 is located between the locking member 5 and the connecting male seat 2 in the transverse X direction. Since the connecting female seat 1 and the connecting male seat 2 are inserted in the transverse X direction, by setting the limiting member 3 on one side of the connecting female seat 1 in the transverse X direction, when the locking member 5 is located at the limiting member 3, the rotating rod 4 is set along the transverse X direction. When the cam 51 rotates and its protrusion applies a force to the limiting plate 31, the rotating rod 4 can pull the connecting male seat 2 along the transverse X direction to move in the insertion direction, thereby further ensuring a reliable connection between the connecting male seat 2 and the connecting female seat 1.

[0037] like Figure 5 As shown, a first chuck 41 is fitted onto the rotating rod 4, in conjunction with... Figure 3 As shown, when the locking member 5 is located at the limiting member 3, the first chuck 41 is located between the limiting plate 31 and the cam 51 to increase the area of ​​the cam 51 acting on the limiting plate 31, which is beneficial to apply force to the limiting plate 31.

[0038] like Figure 5 As shown, a sliding groove 410 is provided on the side of the first chuck 41 facing the cam 51. The sliding groove 410 is elongated, and its length direction is perpendicular to the rotation axis of the cam 51. The outer peripheral surface of the cam 51 abuts against the sliding groove 410. The sliding groove 410 makes the rotation of the cam 51 smoother.

[0039] The first chuck 41 can be made of rubber to increase the friction between the first chuck 41 and the limiting plate 31 and the cam 51, and to prevent the cam 51 from coming loose.

[0040] like Figure 5 As shown, a second chuck 42 and a compression spring 43 are also fitted onto the rotating rod 4. A limit ring 40 is fixed on the rotating rod 4, and the limit ring 40 is close to the connecting male seat 2 relative to the second chuck 42. The two ends of the compression spring 43 abut against the second chuck 42 and the limit ring 40 respectively, and are used to provide a spring force to the second chuck 42 away from the limit ring 40. Figure 3As shown, when the locking member 5 is located at the limiting member 3, the second chuck 42 abuts against the limiting plate 31 under the elastic force of the compression spring 43, and is located on the side of the limiting plate 31 facing the connecting male seat 2. By applying force to the limiting plate 31 through the compression spring 43 and the second chuck 42, the connection strength between the rotating rod 4 and the limiting plate 31 can be improved, making it less likely to fall off from the clearance groove 30. Here, in other embodiments, the second chuck 42, the compression spring 43, and the limiting ring 40 may not be provided.

[0041] In the above embodiments, the locking component is a cam and wrench mating structure. As another embodiment, the locking component may also include a screw and a butterfly knob. One end of the screw is rotatably connected to the butterfly knob. The screw passes through one end of the rotating rod. A screw hole is provided on the limiting component. By screwing the screw into the screw hole, a detachable connection between the locking component and the limiting component is achieved, and the locking component is positioned at the limiting component. The male connector and the female connector can be locked in the plugged-in state.

[0042] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
