[0026] Reference Figures 1-4 An explosion-proof control switch device, comprising:

[0027] The base 1, connecting seat 2, protective shell 3, pull plate 4, insert plate 12 and control switch 13 are connected together. The connecting seat 2 is fixedly connected to the front side of the base 1. The protective shell 3 is movably connected to the inner wall of the connecting seat 2 and is adapted to the connecting seat 2 and the base 1. The pull plate 4 is movably connected to the front side of the protective shell 3. There are two insert plates 12. The two insert plates 12 are symmetrically slidably connected to the inner wall of the protective shell 3. The two insert plates 12 extend to the outside of the protective shell 3 on the side that is far away from each other. The inner wall of the connecting seat 2 is symmetrically provided with two slots. The two insert plates 12 are engaged with the corresponding slots. The control switch 13 is movably connected to the inner wall of the connecting seat 2.

[0028] The limiting mechanism is connected to the insert plate 12 and is used to fix the protective shell 3.

[0029] Through the above-mentioned mechanism: the cooperation between the connecting seat 2 and the protective shell 3 facilitates the protection of the control switch 13; the movement of the pull plate 4 facilitates the movement of the limiting mechanism; the limiting mechanism can drive the movement of the insert plate 12; and the cooperation between the insert plate 12 and the slot facilitates the fixation of the protective shell 3.

[0030] As a preferred embodiment of the present invention, the limiting mechanism includes: a connecting plate 5, a movable plate 6, two connecting frames 8 and two unlocking plates 9;

[0031] The movable plate 6 is slidably connected to the top inner wall of the protective shell 3. The connecting plate 5 is fixedly connected to the front side of the movable plate 6, and the front side of the connecting plate 5 extends to the outside of the protective shell 3. The front side of the connecting plate 5 is fixedly connected to the rear side of the pull plate 4. Two connecting brackets 8 are symmetrically rotatably connected to the bottom of the movable plate 6. Two unlocking plates 9 are symmetrically slidably connected to the inner wall of the protective shell 3. The sides of the two unlocking plates 9 that are close to each other are rotatably connected to the sides of the two connecting brackets 8 that are far apart from each other. The sides of the two unlocking plates 9 that are far apart from each other are respectively connected to the sides of the two insert plates 12 that are close to each other. The side is fixedly connected. When the pull plate 4 moves, it will drive the connecting plate 5 to move, thereby pulling the movable plate 6 forward. At this time, the movement of the movable plate 6 will compress the limiting spring 7. The movement of the movable plate 6 will drive the connecting frame 8. The movement of the connecting frame 8 will pull the two unlocking plates 9 to move closer to each other. The guide frame 10 can conveniently limit the unlocking plate 9, so that the unlocking plate 9 can move laterally stably. When the unlocking plate 9 moves, it will compress the reset spring 11. At the same time, the movement of the unlocking plate 9 will drive the insert plate 12 to move laterally and disengage from the slot, so that the protective shell 3 is unlocked.

[0032] As a preferred embodiment of this utility model, the inner wall of the protective shell 3 is symmetrically fixedly connected with guide frames 10, and there are two guide frames 10. The two guide frames 10 pass through the corresponding unlocking plates 9, and the unlocking plates 9 are easily guided to move laterally through the guide frames 10.

[0033] As a preferred embodiment of this utility model, a reset spring 11 is fixedly connected to the side of each of the two guide frames 10 that is far apart from each other. The side of each of the two reset springs 11 that is far apart from each other is fixedly connected to the side of each of the two unlocking plates 9 that is close to each other. The spring force of the reset spring 11 makes it easy to push the unlocking plate 9 to reset.

[0034] As a preferred embodiment of this utility model, a guide plate is fixedly connected to the inner wall of the protective shell 3, and a connecting plate 5 passes through the guide plate. The guide plate facilitates the restriction of the connecting plate 5, so that the connecting plate 5 and the pull plate 4 can move stably.

[0035] As a preferred embodiment of this utility model, a limiting spring 7 is fixedly connected to the rear side of the guide plate, and the rear side of the limiting spring 7 is fixedly connected to the front side of the movable plate 6. The elastic force of the limiting spring 7 facilitates the resetting of the movable plate 6.

[0036] It should be noted that the specific model of control switch 13 used is to be selected by those skilled in the art, and the above-mentioned control switch 13 and other related technologies are all existing technologies, which will not be elaborated upon in this solution.

[0037] The working principle of this utility model is as follows: In use, first install the base 1 in a suitable position, then wire the control switch 13 and install it inside the connecting base 2. At this time, pull the pull plate 4 forward. When the pull plate 4 moves, it will drive the connecting plate 5 to move, thereby pulling the movable plate 6 forward. The movement of the movable plate 6 will compress the limit spring 7. The movement of the movable plate 6 will then drive the connecting frame 8. The movement of the connecting frame 8 will pull the two unlocking plates 9 to move closer to each other. The guide frame 10 conveniently limits the unlocking plates 9, ensuring stable lateral movement. When the unlocking plates 9 move, they will compress the limit spring 7. The retracting return spring 11, along with the movement of the unlocking plate 9, causes the insert plate 12 to move laterally. At this time, the insert plate 12 moves into the interior of the protective shell 3. The protective shell 3 is then inserted into the interior of the connecting seat 2, aligning the insert plate 12 with the slot. Then, the pull plate 4 is released, and the limit spring 7, no longer restricted, pushes the movable plate 6 to reset, thereby causing the pull plate 4 to reset. Simultaneously, the retracting spring 11, no longer restricted, pushes the unlocking plate 9 to reset. The movement of the unlocking plate 9 causes the insert plate 12 to reset and engage with the slot, fixing the protective shell 3 in place. Through the cooperation between the protective shell 3 and the connecting seat 2, the control switch 13 is protected.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
