[0013] 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.

[0014] Example:

[0015] See also Figure 1-3 The utility model provides a technical solution: a conversion mechanism for an angular travel position switch applied to a linear travel scene, comprising a bracket 1, a linear travel cylinder 2 is mounted on the upper end of the bracket 1, a piston rod of the linear travel cylinder 2 is mounted with an extension rod 3, a fixed plate 7 is mounted at the lower end of the extension rod 3, and a convex rod 8 is provided on the surface of the fixed plate 7;

[0016] The linear cylinder 2 is connected to the bracket 1 through a plurality of screws. The surface of the bracket 1 has a round opening, and the extension rod 3 is connected to the linear cylinder 2 through the round opening.

[0017] An angular travel switch 5 is installed at the lower part of the bracket 1. A connecting rod 6 is installed on the rotating rod of the angular travel switch 5. A sliding bar hole 9 is provided on the surface of the connecting rod 6. The sliding bar hole 9 is sleeved on the surface of the convex rod 8. The convex rod 8 can drive the connecting rod 6 to rotate through the sliding bar hole 9, and the connecting rod 6 controls the rotation of the angular travel switch 5.

[0018] In this embodiment, if Figure 1 and Figure 3 As shown, a mounting plate 10 is mounted on the surface of the angular travel switch 5 , and the mounting plate 10 is fixedly connected to the bracket 1 . The mounting plate 10 is connected to the bracket 1 using screws.

[0019] In this embodiment, if Figure 1 and Figure 2 As shown, a socket seat 4 is provided on the surface of the fixing plate 7 , and the socket seat 4 is socketed with the extension rod 3 to achieve the connection between the fixing plate 7 and the extension rod 3 .

[0020] In this embodiment, if Figure 3 As shown, the surface of the connecting rod 6 is provided with an adjustment port 12, and the surface of the adjustment port 12 is threaded with a clamping screw 11, so as to realize quick disassembly and assembly connection between the connecting rod 6 and the angular travel switch 5. When the connecting rod 6 is severely worn, it can be replaced.

[0021] Specifically, when in use, when the linear cylinder 2 drives the extension rod 3 to move up and down, the extension rod 3 drives the protruding rod 8 to move through the socket 4 and the fixed plate 7. Since the protruding rod 8 is inserted into the sliding bar hole 9 on the surface of the connecting rod 6, the sliding bar hole 9 leaves space for the movement of the protruding rod 8. When the protruding rod 8 moves up and down, it can smoothly drive the connecting rod 6 to rotate, and the connecting rod 6 drives the angular travel switch 5 to operate. When the linear cylinder 2 is in the switch position, the switch signal of the angular travel switch 5 can be triggered.
