Detailed implementation manners

[0024] To make the objectives, features, and advantages of the present utility model more obvious and understandable, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present utility model.

[0025] See Figures 1 to 4 As shown, the embodiment of the present utility model provides a table leg structure with adjustable length, including:

[0026] A first pipe fitting 10, a hollow space extending along its length direction is formed inside the first pipe fitting 10, and a through-opening 101 extending to the hollow space is formed on the outer wall of the first pipe fitting 10;

[0027] A second pipe fitting 50, the second pipe fitting 50 is inserted into the hollow space inside the first pipe fitting 10, and the second pipe fitting 50 can telescopically move relative to the first pipe fitting 10;

[0028] A locking switch 30, which can move relative to the first pipe fitting 10 to reach a first position and a second position. A locking bite head 302 is provided on the locking switch 30. When the locking switch 30 moves to the first position, the locking bite head 302 passes through the through-opening 101 and abuts against the second pipe fitting 50 so that the second pipe fitting 50 and the first pipe fitting 10 are relatively locked and positioned. When the locking switch 30 moves to the second position, the locking bite head 302 is separated from the second pipe fitting 50 so that the second pipe fitting 50 can move relative to the first pipe fitting 10.

[0029] A length-adjustable table leg structure provided in this embodiment includes a first pipe fitting 10, a second pipe fitting 50, and a locking switch 30. The first pipe fitting 10 and the second pipe fitting 50 are inserted and fitted with each other and can be telescopically adjusted. When adjustment is needed, the insertion length of the second pipe fitting 50 inserted into the first pipe fitting 10 can be adjusted. When adjusted to the appropriate position, after the locking switch 30 passes through the through-opening 101 on the first pipe fitting 10, the locking bite 302 on the locking switch 30 abuts against the second pipe fitting 50, so that the first pipe fitting 10 and the second pipe fitting 50 are locked and positioned and cannot be telescopically moved. When the locking bite 302 disengages from the second pipe fitting 50, the first pipe fitting 10 and the second pipe fitting 50 can move. Since the length of the table leg structure can be adjusted, it can adapt to the uneven ground outdoors. In addition, since the table leg structure can be adjusted steplessly, that is, it can keep any length between the first pipe fitting 10 and the second pipe fitting 50, it is more convenient to use.

[0030] In a further feasible implementation manner of this embodiment, the length-adjustable table leg structure further includes a sleeve 40. The sleeve 40 is sleeved and fixed on the first pipe fitting 10, and the locking switch 30 is hingedly arranged on the sleeve 40.

The locking switch 30 is arranged in the accommodation opening 404. Mounting holes 407 are formed on the side wall of the accommodation opening 404. A hinge shaft 304 is arranged on the side of the locking switch 30. The hinge shaft 304 is rotationally matched with the mounting holes 407. A preset opening 406 corresponding to the through-opening 101 is formed at the bottom of the accommodation opening 404.

[0032] In a further feasible implementation manner of this embodiment, the length-adjustable table leg structure further includes a spring 60. One end of the spring 60 is connected to the locking switch 30, and the other end of the spring 60 is connected to the bottom of the accommodation opening 404.

[0033] In this embodiment, the elastic force of the spring 60 causes the locking bite 302 of the locking switch 30 to abut against the second pipe fitting 50.

[0034] In a further feasible implementation manner of this embodiment, a ring-shaped protrusion 405 is arranged at the bottom of the accommodation opening 404, and the end of the spring 60 is arranged inside the ring-shaped protrusion 405.

[0035] In a further feasible implementation manner of this embodiment, a groove 501 extending along its length direction is formed on the outer wall of the second pipe fitting 50, and the locking bite 302 can pass through the through-opening 101 and extend into the groove 501.

[0036] In a further implementable manner of this embodiment, the width of the groove 501 is the same as the width of the front end of the locking bit 302.

[0037] In a further implementable manner of this embodiment, a limiting tab 402 is formed in the inner hole 401 of the sleeve 40, and the limiting tab 402 cooperates with the groove 501.

[0038] The cooperation between the limiting tab 402 and the groove 501 in this embodiment can play a role in telescopic guidance. In addition, the locking bit 302 in this embodiment is set on the groove 501, which can make the locking more stable.

[0039] In a further implementable manner of this embodiment, the front end of the locking bit 302 is a set surface, and the set surface is an inclined surface.

[0040] The set surface in this embodiment is an inclined surface, which can generate a locking contact force when the second pipe fitting 50 is supported and stressed, making the locking more stable.

[0041] In a further implementable manner of this embodiment, anti-slip lines 303 are formed on the inclined surface.

[0042] In addition, a support head 20 in contact with the bottom surface is provided at the end of the first pipe fitting 10 in this embodiment, and a contact protrusion 301 is provided at the top of the locking switch 30 in this embodiment, and the contact protrusion 301 can facilitate pressing.
