[0030] In the present utility model, unless otherwise clearly defined and limited, the terms "installation", "connection", "connection", "fixation", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0031] In the present utility model, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature.

[0032] Reference Figures 1-6 , an embodiment of the present application shows a telescopic adjustable table bracket, including a main frame 1, a connecting member 2 and a telescopic leg 3; the main frame 1 is used to support a tabletop (not shown), the connecting member 2 is arranged at the bottom of the main frame 1, the connecting member 2 includes a guide plate 21, the guide plate 21 is provided with a hinge hole 22, and an arc-shaped guide hole 23 is also provided with the hinge hole 22 as the center, and a plurality of card slots 24 are recessed along the length direction on the side wall of the arc-shaped guide hole 23 close to the hinge hole 22; a first hollow clamping groove 25 is recessed at the bottom of the guide plate 21; the telescopic leg 3 includes a first rod 31 and a second rod 32, and the first rod 31 and the second rod 32 are threadedly connected; a second hollow clamping groove 314 for inserting the guide plate 21 is opened at the top of the first rod 31, the first rod 31 is hinged to the hinge hole 22 of the guide plate 21 through a positioning pin 311, a long hole 312 is axially opened on the first rod 31, a retaining pin 313 is arranged in the long hole 312, a tension spring 315 is arranged between the retaining pin 313 and the positioning pin 311, the retaining pin 313 is clamped in one of the card slots 24 in the arc-shaped guide hole 23, and the tension spring 315 is arranged in the first hollow clamping groove 25.

[0033] Specifically, as Figures 4-6As shown, under the pulling force of the tension spring 315, the locking pin 313 is locked in one of the card slots 24, so that the first support rod 31 cannot rotate around the positioning pin 311, realizing the relative fixation between the telescopic leg 3 and the main frame 1; when the angle of the telescopic leg 3 needs to be adjusted, the locking pin 313 is pulled along the long slot 312, and the locking pin 313 resists the pulling force of the tension spring 315 and disengages from the card slot 24. After the locking pin 313 disengages from the card slot 24, it enters the arc-shaped guide hole 23. At this time, the first support rod 31 can be rotated to make the first support rod 31 rotate around the positioning pin 311. When adjusted to the appropriate position, the locking pin 313 is released. Under the action of the tension spring 315, the locking pin 313 is snapped into the card slot 24 at the new position, realizing the angle fixation of the telescopic leg 3 again. Among them, the first hollow clamping groove 25 provides an installation space for the tension spring 315.

[0034] In this way, by using the structural cooperation between the connecting member 2 and the telescopic leg 3, the telescopic leg 3 can rotate around the positioning pin 311 to adjust the angle between the telescopic leg 3 and the main frame 1; among them, through the cooperation of the tension spring 315, the locking pin 313 and the card slot 24 on the arc-shaped guide hole 23, the relative fixation between the telescopic leg 3 and the guide plate 21 can be realized, ensuring that the telescopic leg 3 can stably support the main frame 1; only by pulling the locking pin 313 along the long slot 312 to disengage the locking pin 313 from the card slot 24 and enter the arc-shaped guide hole 23, the rotational adjustment of the telescopic leg 3 can be realized, and the operation is simple.

[0035] In some embodiments, as Figure 2 shown, a foot cup 4 is further included. A spherical hinge portion 321 is provided at the bottom end of the second support rod 32, and the foot cup 4 forms a universal hinge with the spherical hinge portion 321. In this way, no matter what angle the telescopic leg 3 is adjusted to, the foot cup 4 and the spherical hinge portion 321 can adaptively rotate, so that the foot cup 4 can stably contact the ground smoothly, ensuring stable support.

[0036] In some embodiments, as Figure 1 shown, the main frame 1 includes two first cross beams 11 arranged in parallel and two second cross beams 12 arranged in parallel, and the first cross beam 11 and the second cross beam 12 are bolted together. In this way, the main frame 1 can be disassembled into loose parts, which is convenient for material transportation and handling.

[0037] In some embodiments, for the convenience of installing the table board, as Figure 1 and Figure 3As shown, a table board mounting member 5 is provided on the first cross beam 11. The table board mounting member 5 includes a horizontal board 51. Vertical boards 52 extend from both edges of the horizontal board 51. Connecting boards 53 extend from the edges of the vertical boards 52. Connecting holes 531 are provided on the connecting boards 53. The horizontal board 51 is arranged at the bottom of the first cross beam 11, and the two vertical boards 52 are arranged on both sides of the first cross beam 11. Among them, the table board is fixed on the first cross beam 11 by passing a bolt through the connecting hole 531 and then threadedly connecting it to the table board, that is, the table board is fixed on the main frame 1.

[0038] Preferably, the two vertical boards 52 are clamped on both sides of the first cross beam 11. In this way, during the installation process, the first cross beam 11 can be clamped by the elastic force between the two vertical boards 52, so that the table board mounting member 5 can be clamped on the first cross beam 11 without falling off, and there is no need to hold the table board mounting member 5 steadily by hand, which is convenient for the installation operation.

[0039] Preferably, as Figure 3 shown, the top surface of the connecting board 53 is lower than the top surface of the first cross beam 11. In this way, when connecting the connecting board 53 and the table board with bolts, after tightening the bolts, the elastic force of the connecting board 53 itself pulls the bolts away from the table board, further locking the screws, which can eliminate the thread clearance and prevent the bolts from loosening, making the connection more stable.

[0040] The above is only the preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
