[0013] 2. The limiting blocks are distributed circumferentially on the insulator body, which helps the linkage block and the insulator body to be always coaxially arranged, and further, is conducive to the synchronous sliding of the limiting blocks into the limiting cavity.

[0014] 3. When the linkage block abuts against the abutment plate, the linkage block can push the elastic abutment member to compress while pushing the abutment plate, so that the elastic abutment member makes room for the limit block.

[0015] 4. The abutment block on the quick release tube can push the abutment plate away from the linkage block as the quick release tube moves, so that the linkage block can drive the limit block to retract and achieve the effect of quickly disassembling the insulator body.

DETAILED DESCRIPTION

[0022] The following will be combined with the attached embodiment of the present utility model Figure 1-4 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example:

[0024] like Figures 1 to 4 As shown, the utility model discloses an insulator that is easy to disassemble and assemble, including an insulator body 1 and a mounting seat 2, wherein one end of the mounting seat 2 is provided with a mounting cavity 21 for inserting the end of the insulator body 1, and the other end is fixedly provided with a mounting plate with a threaded hole 25, and at the same time, a limit cavity 22 is also provided in the mounting cavity 21.

[0025] A plurality of limit blocks 31 are circumferentially arranged on the end of the insulator body 1, and each limit block 31 is slidably arranged on the insulator body 1 relative to the axis of the insulator body 1. At the same time, a linkage block 32 is linked to the side of the limit block 31 facing away from the insulator body 1. The linkage block 32 is coaxially arranged with the insulator body 1 and a hinge rod 33 is arranged between the limit block 31. The two ends of the hinge rod 33 are respectively used to be hinged with the linkage block 32 and the limit block 31. In addition, an elastic pushing member 34 is arranged between the linkage block 32 and the end of the insulator body 1. In this structure, the elastic pushing member 34 can push the linkage block 32 away from the insulator body 1. When the linkage block 32 is away from the insulator body 1, it is pulled by the linkage rod and the limit blocks 31 move closer to each other. When the linkage block 32 is pressed close to the insulator body 1, the limit block 31 slides in the direction away from the insulator body 1.

[0026] An elastic supporting mechanism is arranged in the limiting cavity 22, and the elastic supporting mechanism specifically includes an elastic supporting member 23 and a supporting plate 24, wherein the elastic supporting member 23 is an annular structure, one end of the elastic supporting member 23 is supported against the end of the limiting cavity 22 away from the mounting cavity 21, and the other end is used to support against the limiting block 31. At the same time, the supporting plate 24 is sleeved in the elastic supporting member 23 and fixedly connected to one end of the elastic supporting member 23 close to the mounting cavity 21. In this structure, the supporting plate 24 is used to support against the linkage block 32.

[0027] A quick release mechanism is also provided outside the insulator, and the quick release mechanism specifically includes a quick release tube 41 sleeved on the outside of the insulator body 1. The quick release tube 41 is slidably set on the insulator body 1, and a supporting block 42 is provided on the end of the quick release tube 41 close to the insulator body 1. When the insulator body 1 is installed on the mounting seat 2, the quick release tube 41 is sleeved between the mounting cavity 21 and the insulator body 1. At the same time, the supporting block 42 is pressed by the supporting plate 24 and is supported between the end of the insulator body 1 and the supporting plate 24.

[0028] Finally, the elastic resisting member 23 and the elastic pushing member 34 are both springs.

[0029] The working principle of the above structure is:

[0030] When the insulator body 1 needs to be installed on the mounting seat 2, the quick-release tube 41 is first sleeved on the outside of the insulator body 1, and then inserted into the mounting cavity 21 of the mounting seat 2 together with the insulator body 1. The installation process is as follows: first, the linkage block 32 is abutted against the abutment plate 24, but the end of the insulator body 1 has not yet penetrated to the position where the limit block 31 moves to the limit cavity 22, the linkage block 32 can push the abutment plate 24 to move, and at the same time, the elastic abutment member 23 can shrink with the movement of the abutment plate 24, and thereby reserve a sliding space for the limit block 31. When the end of the insulator body 1 penetrates to the position where the limit block 31 moves to the limit cavity 22, under the action of the elastic pusher 34, the limit block 31 slides into the limit cavity 22. At this time, the linkage block 32 approaches the insulator body 1, and the elastic abutment member 23 can be pressed onto the limit block 31 to thereby fix the end of the insulator body 1 in the mounting seat 2.

[0031] When the insulator body 1 needs to be disassembled, the quick-release cylinder 41 can be pushed, and the abutment block 42 on the quick-release cylinder 41 can push the abutment plate 24 to move and simultaneously shrink the elastic abutment member 23. At this time, under the action of the elastic pushing member 34, the linkage block 32 moves away from the insulator body 1 and brings the limit blocks 31 closer to each other. At this time, the insulator body 1 can be directly removed from the mounting seat 2, and the process is convenient and quick.

[0032] It should also be pointed out that the terms used in the present invention, such as "front", "rear", "vertical", "horizontal", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description.
