[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-8 A limit switch that is easy to install and operate includes a switch component 2. The switch component 2 includes a limit switch body 24. One end of the limit switch body 24 is provided with a movable moving rod 25. The end of the moving rod 25 away from the limit switch body 24 is recessed to form a threaded groove 26. A movable screw 27 is screwed into the inside of the threaded groove 26. A top head 28 is fixedly connected to the free end of the screw 27.

[0026] With the above technical solution, before using the switch 2, the limit switch body 24 is fixed to the elevator. After the limit switch body 24 is fixed, when the top head 28 on the limit switch body 24 touches an object, the top head 28 will drive the screw 27 to move, thereby triggering the limit switch body 24. When it is necessary to adjust the trigger length of the limit switch body 24, the top head 28 is rotated so that the top head 28 drives the screw 27 to rotate.

[0027] After the position of the mandrel 28 is adjusted, to prevent the screw 27 and the mandrel 28 from moving accidentally, such as Figure 1 , Figure 2 and Figure 8As shown, a movable limiting rod 29 is screwed onto the circumferential surface of the movable rod 25, and the free end of the limiting rod 29 extends into the interior of the threaded groove 26 to press the screw 27.

[0028] In this embodiment, after the positions of the screw 27 and the top head 28 are adjusted, the limiting rod 29 on the moving rod 25 is rotated to move the limiting rod 29 relative to the moving rod 25 until the free end of the limiting rod 29 moves into the inside of the threaded groove 26 and presses the free end of the limiting rod 29 against the screw 27, thereby fixing the screw 27 and the top head 28 and preventing the screw 27 and the top head 28 from rotating accidentally.

[0029] Furthermore, in this utility model, to facilitate the installation of the limit switch body 24, such as... Figures 1-8 As shown, the limit switch also includes a pre-fixed fixing member 1. One side of the fixing member 1 is open to form a connecting groove 12. A base plate 21 is fixedly connected to one side of the limit switch body 24. A positioning hole 23 is provided on the base plate 21. The outer side of the fixing member 1 is recessed to form a limiting hole 17 and a side hole 18. The limiting hole 17 is located on one side of the side hole 18. A movable connecting plate 15 is provided on one side of the fixing member 1. A spring 16 is fixedly connected inside the side hole 18. The free end of the spring 16 is fixedly connected to the connecting plate 15. A positioning rod 19 is fixedly connected to one side of the connecting plate 15. The positioning rod 19 is located on one side of the spring 16. The free end of the positioning rod 19 must pass through the limiting hole 17 and be inserted into the positioning hole 23.

[0030] In this embodiment, when the limit switch body 24 needs to be installed, the fixing member 1 is fixed in advance. After the fixing member 1 is fixed, the base plate 21 is engaged with the connecting groove 12 on the fixing member 1. When the base plate 21 is engaged with the connecting groove 12, the base plate 21 will push the positioning rod 19. When the positioning rod 19 moves, it will stretch the spring 16. When the positioning rod 19 approaches the positioning hole 23 on the base plate 21, it will rebound through the spring 16, thereby pulling the connecting plate 15 to move. The connecting plate 15 drives the positioning rod 19 to move, so that the positioning rod 19 passes through the limiting hole 17 and is inserted into the positioning hole 23 on the base plate 21, thereby fixing the base plate 21 and the limit switch body 24 and completing the installation of the limit switch body 24. When the limit switch body 24 needs to be disassembled, the connecting plate 15 is pulled, so that the connecting plate 15 stretches the spring 16 and drives the positioning rod 19 to move to the outside of the limiting hole 17, so that the limit switch body 24 can be disassembled.

[0031] Specifically, in one embodiment, regarding the aforementioned fastener 1, as... Figures 1-7 As shown, the fastener 1 includes a fixing frame 11, and side plates 13 are fixedly connected to both sides of the fixing frame 11 on the outside. The side plates 13 are provided with through holes 14.

[0032] In this embodiment, when it is necessary to fix the fastener 1, the fixing bracket 11 is placed at the position where it needs to be fixed, and then the bolt is passed through the through hole 14 on the side plate 13 and rotated until the bolt passes through the through hole 14 and enters into other objects, thus completing the fixing of the side plate 13.

[0033] To facilitate the insertion of the positioning rod 19 into the positioning hole 23, such as Figure 8 As shown, two guide grooves 22 are symmetrically formed on one side of the substrate 21. The limit switch body 24 is located between the two guide grooves 22. The guide grooves 22 are connected to the positioning holes 23. The side of the guide grooves 22 away from the positioning holes 23 extends to the edge of the substrate 21 and opens to form an opening. The diameter of the opening is larger than the diameter of the positioning holes 23.

[0034] In this embodiment, when the substrate 21 engages with the connecting groove 12 on the fixing frame 11, it cooperates with the guide groove 22, and since the diameter of the opening is larger than the diameter of the positioning hole 23, the positioning rod 19 can be easily inserted into the positioning hole 23.

[0035] Furthermore, in this utility model, in order to improve the tightness of the fixing bracket 11 after fixing, such as Figure 7 As shown, an anti-slip plate 110 is glued to the side of the fixing frame 11 away from the connecting plate 15, and an anti-slip groove 111 is formed by recessing on the anti-slip plate 110.

[0036] In this embodiment, after the fixing frame 11 is fixed, the anti-slip plate 110 and the anti-slip groove 111 cooperate to make the fixing frame 11 more secure.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
