[0043] Referring to Figures 1-5 , a basic embodiment of the first aspect of this utility model provides a connection structure, including:

[0044] A table leg 100, provided with a through hole 110;

[0045] A cross beam 200, provided with a connecting member 210, and the connecting member 210 can be inserted into the upper end of the through hole 110;

[0046] A fastening member 300, abuts against the connecting member 210, drives the fastening member 300 to move from top to bottom, so that the connecting member 210 moves from top to bottom, and the connecting member 210 is clamped to the lower end of the through hole 110.

[0047] According to the embodiments of the present utility model, by arranging in this way, at least the following effects can be achieved. By inserting the connecting member 210 on the cross beam 200 into the upper end of the through hole 110, the cross beam 200 can be preliminarily installed on the table leg 100. Driving the fastener 300 to move from top to bottom causes the connecting member 210 to move from top to bottom accordingly. Since the connecting member 210 is clamped to the lower end of the through hole and the connecting member 210 cannot pass through the through hole 110, and the fastener 300 restricts the up and down movement of the connecting member 210, the connecting member 210 can be installed and fixed on the table leg 100. This structure does not directly connect the cross beam through the bolt 400. The cross beam 200 is installed or removed on the table leg 100, with a simple structure and convenient operation. One fastener 300 can reinforce two cross beams 200, reducing the difficulty of parts assembly.

[0048] The first embodiment that can restrict the connecting member from passing through the upper end of the through hole 110 but not through the through hole 110 is that the width of the upper end of the through hole 110 is greater than the width of the lower end of the through hole 110. The width of the through hole 110 gradually decreases from top to bottom. The diameter of the through hole 110 continuously decreases from top to bottom, and the diameter width continuously changes. When the connecting member 210 moves from top to bottom, the width of the through hole 110 continuously decreases, which can prevent the connecting member 210 from passing through the through hole 110 and fix the connecting member 210 at the corresponding position.

[0049] The second embodiment that can restrict the connecting member from passing through the upper end of the through hole 110 but not through the through hole 110 is that a limiting member is provided at the lower end of the through hole, and the limiting member is used to restrict the connecting member 210 from passing through the lower end of the through hole. The limiting member is a baffle plate provided at the lower end of the through hole, and the baffle plate can block the movement of the connecting member to achieve the purpose of clamping the connecting member 210.

[0050] In some embodiments, it further includes a bolt 400. The table leg 100 is provided with a threaded hole, and the bolt 400 is matched with the threaded hole so that the fastener 300 can move from top to bottom. Driving the fastener 300 to move up and down by screw thread cooperation through the bolt 400 causes the fastener 300 to move up and down accordingly. Threaded connection is a widely used detachable fixed connection, which has the advantages of simple structure, reliable connection, convenient installation and disassembly, etc. After the thread is installed, the tabletop 600 covers the fastener 300, and the tabletop 600 can restrict the up and down movement of the fastener 300, improving the installation stability of the fastener 300.

[0051] In some embodiments, the connecting member 210 includes a locking portion 211 and a connecting rod portion 212. The locking portion 211, the connecting rod portion 212, and the cross beam 200 are arranged in sequence. The width of the upper end of the through hole 110 >= the diameter of the locking portion 211 >= the diameter of the lower end of the through hole 110, and the diameter of the connecting rod portion 212 <= the diameter of the lower end of the through hole 110. The diameters of the locking portion 211 and the connecting rod portion 212 are uniformly the same. The locking portion 211 can pass through the upper end of the through hole 110 but cannot pass through the lower end of the through hole 110, and the connecting rod portion 212 can pass through the upper end and the lower end of the through hole 110. Therefore, when the connecting member 210 is at the upper end of the through hole 110, the connecting member 210 is in an active state, and when the connecting member 210 is at the lower end of the through hole 110, the connecting member 210 is in a locked state.

[0052] In some embodiments, a clamping member 500 is further included. The clamping member 500 is provided with two connecting blocks 520, and the cross beam 200 is provided with a clamping groove 220. The two connecting blocks 520 can be respectively inserted into the clamping grooves 220 of two adjacent cross beams 200. Through the two connecting blocks 520 on the clamping member 500, the two cross beams 200 are fixed, so that there is a mutual pulling force between the two cross beams 200, improving the tightness between the cross beam 200 and the tabletop 600; secondly, a triangular arrangement is formed between the two cross beams 200 and the clamping block, with high stability.

[0053] Furthermore, the clamping member 500 is provided with a tabletop 600 mounting hole for mounting the tabletop 600, so that the tabletop 600 is fixed on the cross beam 200 and the table legs 100. The clamping member 500 is used to connect the tabletop 600, and there is a mutual acting force between the clamping member 500 and the tabletop 600, so that the tabletop 600 is fixed on the cross beam 200.

[0054] In some embodiments, the connecting block 520 extends upward, and the connecting block can be inserted into the clamping groove 220 from bottom to top. The connecting block 520 is arranged from bottom to top, and the connecting block 520 and the tabletop 600 cooperate with each other. There is a mutual acting force between the clamping member 500 and the tabletop 600, so that the tabletop 600 is fixed on the cross beam 200, which can improve the installation stability.

[0055] In some embodiments, the clamping member 500 is provided with a connecting hole 510 for connecting the tabletop 600. The tabletop 600 is fixed on the cross beam 200 by screwing through the connecting hole 510 to connect the tabletop 600.

[0056] In some embodiments, the fastener 300 is provided with a slot 310, and the connecting member 210 can be inserted into the slot 310. When the connecting member 210 is installed, it is located in the slot 310, which can limit the movement direction of the connecting member 210 except for the axial direction and the up and down directions, enabling the fastener 300 to move in the up and down direction and preventing the connecting member 210 from shaking and affecting the stability.

[0057] In some embodiments, the cross beam 200 and the connecting member 210 are separately provided. The cross beam 200 and the connecting member 210 belong to two different components, which is convenient for modular production; during production, they are produced separately and then connected by welding to connect the two components, improving production efficiency and reducing production costs.

[0058] It should be noted that in this specification, several embodiments of the present invention can be described by terms such as "one embodiment", "some embodiments", "basic embodiment", "extended embodiment", etc. The specific features, structures, materials or characteristics in several embodiments can be combined under the premise of conforming to the principles and purposes of the present invention.
