[0005] The purpose of the utility model can be achieved through the following technical solutions: A push switch with self-locking and anti-self-locking comprises: a switch body, a trigger, a push button, a metal baffle, a metal travel plate and a shell, the trigger is rotatably arranged on the front side of the switch body, the push button is elastically slidably arranged on the right side of the switch body, the metal baffle is connected to the upper end of the push button, the metal travel plate is fixed to the upper end of the trigger, and the metal travel plate is provided with a slide groove for the metal baffle to slide, the slide groove comprises a travel groove, an anti-self-locking groove and a self-locking groove, the anti-self-locking groove is connected and arranged on the right side of the upper end of the travel groove, the self-locking groove is connected and arranged on the left side of the lower end of the travel groove, and the shell is arranged on the switch body and is located outside the metal baffle.

[0006] As a further improvement, a groove is provided in the switch body, the push button is slidably arranged in the groove, a spring is provided in the groove, and one side of the spring is connected to the push button.

[0007] As a further improvement, a baffle is provided in the self-locking groove.

[0008] As a further improvement, a circular arc pressing portion is provided on the surface of the trigger.

[0009] Compared with the prior art, the push switch with self-locking and anti-self-locking function of the utility model has the following beneficial effects:

[0010] By adding travel grooves, anti-self-locking grooves and self-locking grooves inside the metal travel plate in conjunction with elastic metal baffles, the trigger action is coordinated with the push button action to achieve the self-locking and anti-self-locking functions of the switch, which not only ensures safety but also improves human comfort.

[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] Below is a combination of the embodiments and the attached Figures 1 to 6 , the technical solution of the utility model is further elaborated.

[0021] Example 1

[0022] A push switch with self-locking and anti-self-locking, comprising: a switch body 1, a trigger 2, a push button 3, a metal baffle 4, a metal travel plate 5 and a shell 6, wherein the trigger 2 is rotatably arranged on the front side of the switch body 1, the push button 3 is elastically slidably arranged on the right side of the switch body 1, the metal baffle 4 is connected to the upper end of the push button 3, the metal travel plate 5 is fixed to the upper end of the trigger 2, and the metal travel plate 5 is provided with a slide groove 51 for the metal baffle 4 to slide, the slide groove 51 comprises a travel groove 511, an anti-self-locking groove 512 and a self-locking groove 513, the anti-self-locking groove 512 is connected and arranged on the right side of the upper end of the travel groove 511, and the self-locking groove 513 is connected and arranged on the left side of the lower end of the travel groove 511, and the shell 6 is arranged on the switch body 1 and located outside the metal baffle 4.

[0023] As a further preferred embodiment, a groove 11 is provided in the switch body 1 , and the push button 3 is slidably disposed in the groove 11 . A spring 12 is provided in the groove 11 , and one side of the spring 12 is connected to the push button 3 .

[0024] As a further preferred embodiment, a baffle 514 is provided in the self-locking groove 513 .

[0025] As a further preferred embodiment, a circular arc pressing portion 21 is provided on the surface of the trigger 2 to make pressing the trigger 2 more comfortable.

[0026] like Figure 1 to Figure 6 As shown, the use principle of the utility model is as follows: during use, the metal blocking piece 4 is stuck in the anti-self-locking groove 512 in the initial position. When the trigger 2 is pressed, the metal blocking piece 4 is in the anti-self-locking groove 512, and the metal travel plate 5 connected to the trigger 2 cannot move forward and backward, so that the switch cannot be started. At this time, it has the anti-self-locking function; pushing the push button 3, the metal blocking piece 4 slides from the anti-self-locking groove 512 into the travel groove 511, and the metal blocking piece 4 can move forward and backward in the travel groove 511, and the metal travel plate 5 connected to the trigger 2 can move forward and backward to drive The switch moves forward and backward, the trigger 2 is pressed to the maximum stroke, and the push button 3 is continued to be pushed, so that the push button 3 slides into the self-locking groove 513 with the metal baffle 4. A baffle 514 is provided on the side of the self-locking groove 513, so that the metal baffle 4 is hung on the baffle 514. At this time, there is a self-locking function, and the trigger 3 is pressed again, and the metal baffle 4 disengages from the baffle 514. The reaction force of the spring 12 makes the push button 3 slide into the travel groove 511 with the metal baffle 514. When the trigger 3 is placed in the initial position, the metal baffle 4 returns to the anti-self-locking groove 512 again, and the whole action is completed.

[0027] By adding a metal mechanical structure, the switch is given a self-locking and anti-self-locking function, which not only ensures safety but also improves human 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.
