[0030] The following will be combined with the drawings in the embodiments of the utility model to 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 the embodiments. Based on the embodiments in 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.
[0031] Reference Figure 2 and Figure 4 The utility model provides an embodiment: a limit block for installing a limit switch, comprising a base 1, a fixed rail 2 is fixedly connected to the top of the base 1, a connecting column 5 is slidably connected to the outside of the fixed rail 2, a groove 23 is provided inside the connecting column 5, a threaded rod 21 is rotatably connected to the inside of the groove 23, a threaded sleeve 20 is threadedly connected to the outside of the threaded sleeve 20, two rotating shafts 22 are fixedly connected to the outside of the two rotating shafts 22, a connecting rod 19 is rotatably connected to one end of the connecting rod 19, a fixed rod 24 is fixedly connected to the outside of the fixed rod 24, an insert block 18 is fixedly connected to the outside of the fixed rod 24, a connecting groove 12 is provided on the top of the connecting column 5, a limit block 4 is arranged on the top of the connecting column 5, vertical plates 10 are fixedly connected to the bottom of the limit block 4, and a moving component is installed on the outside of the fixed rail 2.
[0032] Specifically, by rotating the handle 6 with external force, under the action of the external force, the threaded rod 21 inside the connecting column 5 starts to rotate, and the rotation of the threaded rod 21 causes the threaded sleeve 20 to move along the outside of the threaded rod 21. The movement of the threaded sleeve 20 drives the rotating shaft 22 to rotate, and then the connecting rod 19 swings. The movement of the connecting rod 19 causes the fixing rod 24 to move inside the groove 23. The movement of the fixing rod 24 causes the insert block 18 to disengage from the inside of the limiting hole 11, so that the limiting hole 11 is disengaged from the inside of the connecting groove 12. When the limiting hole 11 is disengaged from the inside of the connecting groove 12, the staff can easily disassemble the limiting block 4 for replacement.
[0033] Reference Figure 1 and Figure 3 The moving component includes a slide plate 8, one side of the slide plate 8 is slidably connected to the outside of the fixed track 2, a slide groove 14 is provided inside the slide plate 8, a pull rod 13 is slidably connected inside the slide groove 14, a spring 15 is sleeved outside the pull rod 13, one end of the spring 15 is fixedly connected to a moving plate 16, one side of the moving plate 16 is fixedly connected to a block 17, the top of the slide plate 8 is fixedly connected to a connecting column 5, and a plurality of sockets 9 are provided outside the fixed track 2.
[0034] Specifically, when the staff pulls the pull rod 13, the movable plate 16 will move accordingly, and the spring 15 will be compressed. The movement of the movable plate 16 causes the block 17 to disengage from the current socket 9 and move to the inside of the slide groove 14. After the block 17 moves to the inside of the slide groove 14, it will push the limit block 4 to the left, so that it can move to the required position as needed, thereby limiting the movement range of the limit switch body 3. At the same time, the slide plate 8 will also move along the outside of the fixed track 2, so that the entire movable assembly can adjust the position of the limit block 4 as needed. When it moves to the required position, the block 17 is inserted into another socket 9 again to stabilize the position of the limit block 4.
[0035] Reference Figure 4 One end of the threaded rod 21 extends to the outside of the connecting column 5 and is fixedly connected to the handle 6. The outside of the fixed rod 24 is slidably connected to the inside of the groove 23. The bottom end of the vertical plate 10 is slidably connected to the inside of the connecting groove 12. A limiting hole 11 is opened on the outside of the vertical plate 10, and the outside of the plug block 18 is slidably connected to the inside of the limiting hole 11.
[0036] Specifically, by providing the handle 6, it is convenient for the staff to rotate the threaded rod 21, so that when the threaded sleeve 20 moves, the fixed rod 24 is connected to the inside of the groove 23 by sliding. This connection allows the fixed rod 24 to remain stable when moving inside the groove 23, thereby allowing the insert block 18 to disengage from the inside of the limiting hole 11.
[0037] Reference Figure 3One end of the pull rod 13 extends to the outside of the slide plate 8 and is fixedly connected to the handle 7. The outside of the block 17 is fitted against the inside of the socket 9. The other end of the spring 15 is fixedly connected to the inside of the slide plate 8. The movable plate 16 is slidably connected to the inside of the slide groove 14. The top of the fixed track 2 is slidably connected to the limit switch body 3.
[0038] Specifically, by pulling the handle 7 , the pull rod 13 moves, so that the block 17 is separated from the inside of the socket 9 , and the limit switch body 3 slides on the top of the fixed track 2 , so that the limit switch body 3 moves at a uniform speed.
[0039] Working principle: When the staff needs to replace the limit block 4, the handle 6 on the outside of the connecting column 5 can be rotated by external force, so that the threaded rod 21 is rotated under the drive of the handle 6, thereby driving the threaded sleeve 20 to move along the outside of the threaded rod 21, and then under the connection of the rotating shaft 22, the connecting rod 19 is swung, and under the drive of the connecting rod 19, the fixing rod 24 moves inside the groove 23, so that the insert block 18 is disengaged from the inside of the limit hole 11 under the drive of the fixing rod 24, and then the limit hole 11 is disengaged from the inside of the connecting groove 12, and the limit block 4 can be disassembled therefrom, which is convenient for the staff to operate;
[0040] Secondly, by pulling the pull rod 13 inside the slide plate 8 outward, the movable plate 16 moves, wherein the spring 15 is in a compressed state. However, driven by the movable plate 16, the block 17 disengages from the socket 9 and moves to the inside of the slide groove 14, and then pushes the limit block 4 to the left, and at the same time the slide plate 8 moves along the outside of the fixed track 2. When it moves to the required position, the block 17 is inserted into another socket 9 again, so that the staff can adjust the position of the limit block 4 by pulling the pull rod 13, so as to limit the movement range of the limit switch body 3, and facilitate the staff to monitor and operate.
[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
