DETAILED DESCRIPTION

[0018] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0019] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] The following is combined with the embodiments and attached Figures 1 to 6 , the technical solution of the utility model is further elaborated.

[0021] Example 1

[0022] A push switch structure with self-locking and anti-self-locking, comprising: a shell 1, a trigger 2, a push button 3, a push button block 4, a spring 5 and a switch body 7, wherein the trigger 2 is rotatably arranged at the upper end of the shell 1, the push button block 4 is slidably arranged at the front end of the shell 1, the push button 3 is connected to one end of the push button block 4, a transverse rib 2 41 is arranged at the bottom of the push button block 4, the spring 5 is arranged in a spring groove 11 between the push button block 4 and the shell 1, a transverse rib 1 21 and a self-locking block 22 are arranged at the upper end of the trigger 2, a sliding groove 26 is arranged between the transverse rib 1 21 and the self-locking block 22, a baffle part 1 23 located behind the transverse rib 1 21 is arranged on the rear side of the right end of the self-locking block 22, a baffle part 24 is arranged on the front side of the right end of the self-locking block 22, a self-locking groove 25 is arranged on the left side of the baffle part 24, and the switch body 7 is arranged in the shell 1 and at the rear end of the trigger 2.

[0023] like Figure 1 to Figure 6 As shown, the use principle of the utility model is: in the initial position, the horizontal rib 1 21 on the trigger 2 and the horizontal rib 2 41 on the push button block 4 abut against each other. When the trigger 2 is pressed, the horizontal rib 1 21 and the horizontal rib 2 41 abut against each other, so that the trigger cannot move to the switch start position, so that the switch cannot be started, and at this time it has an anti-self-locking function; pushing the push button 3 drives the push button block 4 to move with the horizontal rib 2 41, at this time the two abutting horizontal ribs 1 21 and the horizontal rib 2 41 are disengaged, and after pushing a certain distance, the horizontal rib 2 41 is blocked by the baffle part 1 23 and cannot be pushed any further. At this time, the horizontal rib 2 on the push button block 4 41 can move forward and backward in the slide groove 26, and the trigger can drive the switch to move forward and backward. When the trigger is pressed to the maximum stroke, continue to push the push button block 4, so that the push button block 4 slides into the self-locking groove 25 with the second transverse rib 41. A baffle 2 is provided on the side of the self-locking groove, so that the second transverse rib 41 is hung on the baffle part 24. At this time, there is a self-locking function. Press the trigger again, the second transverse rib 41 disengages from the baffle part 24, and the reaction force of the spring 5 makes the push button 3 slide into the slide groove 26 with the second transverse rib 41. When the trigger returns to the initial position, the second transverse rib 41 returns to the position against the first transverse rib 21 again, and the whole action is completed.

[0024] By designing a self-locking and anti-self-locking structure on the switch trigger and cooperating with the elastic sliding push button, the switch is provided with self-locking and anti-self-locking functions, which not only ensures safety but also improves human comfort.

[0025] As a further preferred embodiment, the end surface of the push button 3 is provided with an arc guide surface to improve pushing comfort.

[0026] As a further preferred embodiment, the self-locking groove 25 is provided with an arc chamfer, so that the second transverse rib 41 can slide into and out of the self-locking groove 25 more smoothly.

[0027] As a further preferred embodiment, the trigger 2 is provided with an arc pressing groove 6 to improve the pressing comfort.

[0028] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
