[0035] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] Example 1

[0037] like Figures 1-4 The push-button switch shown has an anti-loosening and anti-retraction structure, which mainly includes a housing 10, a movable frame 20 that can move freely up and down inside the housing, and a cap 30. It should be noted that the push-button switch also includes necessary components such as a fixed base, contacts, and contact feet. In this embodiment, the movable frame 20 is the component used to install the moving contact, and its main function is to move up and down to drive the moving contact to cooperate with the stationary contact to conduct the circuit.

[0038] Specifically, the movable frame 20 can be an integral structure or a split structure. That is, the movable frame 20 is composed of a first movable body 201 and a second movable body 202. Optionally, according to actual needs, the first movable body 201 and the second movable body 202 can be an integral structure, that is, integrally injection molded or integrally processed by an injection mold; the first movable body 201 and the second movable body 202 can also be a split structure, that is, connected by fastening methods such as buckles, threads, and pins.

[0039] The first movable body 201 is provided with a first connecting portion 2012 and a protrusion 2011, with the protrusion 2011 located below the first connecting portion 2012. In this embodiment, the first connecting portion 2012 has an external thread. The bottom of the cap 30 is provided with a second connecting portion 301 and a ratchet portion 302, with the ratchet portion 302 located below the second connecting portion 301. In this embodiment, the second connecting portion 301 has an internal thread, and it mainly engages with the first connecting portion 2012 for connection. That is, the cap 30 is fitted onto the top of the first movable body 201 through the engagement of the second connecting portion 301 and the first connecting portion 2012.

[0040] The protrusion 2011 and the ratchet 302 cooperate to form an anti-loosening and anti-retraction structure. Specifically, the ratchet 302 consists of multiple protrusions inclined in the same direction, and the protrusion 2011 engages with the ratchet 302, meaning the protrusion 2011 is also a toothed block with the same inclination direction as the ratchet 302. The ratchet 302 has toothed grooves 3021 inclined in the same direction. Further, the inclination direction of the ratchet 302 is the same as the rotation direction of the external thread of the first connecting part 2012. That is, when the cap 30 and the first movable body 201 rotate in the rotation direction of the external thread, the protrusion 2011 and the ratchet 302 engage in a forward engagement, and the protrusion 2011 can be displaced into the next toothed block; if it rotates in the opposite direction to the rotation direction of the external thread, the protrusion 2011 abuts against the groove 3021 to form an anti-loosening and anti-retraction structure.

[0041] It should be noted that after the cap 30 is connected to the first movable body 201, pressing the cap 30 will drive the movable frame 20 to move up and down. This anti-loosening and anti-retraction structure is mainly used to prevent the cap 30 from falling off during use.

[0042] Example 2

[0043] like Figure 5 As shown, the difference from Embodiment 1 is that in this embodiment, the ratchet portion 302 of the cap 30 is disposed above the second connecting portion 301. It should be noted that the bottom of the cap 30 is provided with a hollow connecting portion, i.e., a convex wall, and the second connecting portion 301, i.e., the internal thread, is disposed on the inner side of the connecting portion. The second connecting portion 301 is also disposed on the inner side of the connecting portion.

[0044] The protrusion 2011 is located above the first connecting part 2012, corresponding to the position of the ratchet part 302.

[0045] Example 3

[0046] like Figure 6 As shown, the difference from Embodiment 1 and Embodiment 2 is that the ratchet portion 302 of the cap 30 is located above the second connecting portion 301. Specifically, the second connecting portion 301 is disposed on the top of the connecting portion, while the protrusion 2011 can be located on the side or top surface of the first movable body 201. That is, the position of the protrusion 2011 depends on the shape of the groove 3021 of the ratchet portion 302.

[0047] If the shape of the groove 3021 is the same as that of the groove 3021 in Embodiments 1 and 2, then the protrusion 2011 can be located on the side of the first movable body 201, only needing to be above the first connecting part 2012. For example... Figure 7 As shown, if the groove is turbine-shaped, the protrusion 2011 is located on the top surface of the first movable body 201 and is also distributed in a turbine shape.

[0048] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention. The technical content for which protection is sought in the present invention has been fully described in the claims.
