DETAILED DESCRIPTION

[0020] In order to make the purpose and the advantage of the utility model more clearly, the following specific description of the utility model is combined with examples, and it should be understood that the following text is only used to describe one or several specific implementation manners of the utility model, and does not strictly limit the protection scope of the utility model.

[0021] As Figures 1-2As shown, a lifting sleeve structure with reverse buckle includes a lifting pipe 1, the bottom of the lifting pipe 1 is provided with a mounting plate 6, and the mounting plate 6 is buckled with the bottom end of the lifting pipe 1 through a buckle assembly, the lifting pipe 1 is made of a plurality of sleeves 101 which are sequentially sleeved from outside to inside, the inner side of each sleeve 101 is provided with a limiting sliding groove 102, the outer wall of the next sleeve 101 is provided with a limiting sliding block 103 which is slidingly connected with the limiting sliding groove 102, and the bottom of each sleeve 101 is provided with a stop block 104 for limiting the limiting sliding block 103; the outer wall of each lifting pipe 1 and above the limiting sliding block 103 is provided with two reverse buckles 105, which are used for preventing the sleeve 101 from falling off when the limiting sliding block 103 accidentally falls off, in cooperation with the stop block 104.

[0022] According to the above structure, when the lifting pipe 1 is extended, the extension sequence is from the large pipe to the small pipe, the small pipe limiting sliding block 103 moves to the outside of the large pipe end stop block 104 and stops, the next sleeve 101 continues to extend until all the sleeves 101 are extended; each sleeve 101 is arranged with eight reverse buckles 105 on four sides, which can effectively prevent the sleeve 101 from falling off when the limiting sliding block 103 accidentally falls off, in cooperation with the pipe end stop block 104; when the lifting pipe 1 is retracted, the extension sequence is from the small pipe to the large pipe, the pipe end stop block 104 of each sleeve 101 contacts each other and is retracted in turn until it stops at the specified position.

[0023] As shown in Figures 1-2 the inner wall of each sleeve 101 and on both sides of the limiting sliding groove 102 is provided with a guide groove 3, and the outer wall of the next sleeve 101 is provided with a guide rail 2 which is dampingly slid with the guide groove 3.

[0024] According to the above structure, the guide rail 2 can be dampingly slid in the guide groove 3, so that the movement of the sleeve 101 is relatively stable, and the lifting pipe 1 after extension or retraction can be stably fixed, thereby increasing the practicability of the equipment.

[0025] As shown in Figure 1 and Figure 3 the bottom end of the lifting pipe 1 is provided with a plug-in block 4, the outer wall of the plug-in block 4 is fixed with two clamping blocks 5, the top of the mounting plate 6 is fixed with a fixed pipe 7 which cooperates with the plug-in block 4, the outer wall of the fixed pipe 7 is provided with two clamping grooves 8 which cooperate with the clamping blocks 5, the clamping grooves 8 are composed of L grooves and vertical grooves, and the bottom end of the L groove is provided with a vertical groove; the inside of the fixed pipe 7 is slidingly provided with a resilient top plate 9, and the bottom of the resilient top plate 9 is provided with a spring which is fixed with the inside of the fixed pipe 7.
