[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0017] like Figure 1-3 As shown, the utility model is an explosion-proof switch which is easy to install, comprising an explosion-proof switch body 1 and a T-shaped mounting strip 3. A T-shaped assembly groove 2 is provided on the back of the explosion-proof switch body 1. The T-shaped mounting strip 3 is inserted into the inside of the T-shaped assembly groove 2. A plurality of card slots 4 are equidistantly provided on both sides of the T-shaped mounting strip 3. A plurality of card blocks 6 are equidistantly provided on both sides of the inner wall of the T-shaped assembly groove 2. The plurality of card blocks 6 are engaged and connected with the corresponding card slots 4.

[0018] Specifically, by adapting the T-shaped assembly groove 2 opened on the back of the explosion-proof switch body 1 to the T-shaped mounting strip 3, the explosion-proof switch body 1 can slide on the surface of the T-shaped mounting strip 3, and the clamping blocks 6 provided on both sides of the inner wall of the T-shaped assembly groove 2 are engaged and fixed with the clamping grooves 4 opened on both sides of the T-shaped mounting strip 3, which effectively improves the convenience of installation of the explosion-proof switch body 1.

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model is an explosion-proof switch that is easy to install. Both sides of the inner wall of the T-shaped assembly groove 2 are provided with installation grooves 7, and connecting plates 8 are nested inside the two installation grooves 7. The side surfaces of the connecting plates 8 are fixedly connected to one side of the plurality of clamping blocks 6.

[0020] Tooth grooves 9 are provided at the tops of the multiple blocks 6, and rotating rods 5 are rotatably connected to the inner walls of the mounting grooves 7 on both sides. One end of the rotating rod 5 passes through the mounting grooves 7 and extends to the outside. Multiple gears 10 are equidistantly fixedly installed on the surface of the rotating rod 5, and the multiple gears 10 are meshed and connected with the corresponding tooth grooves 9.

[0021] The size of the end of the clamping block 6 is matched with the inner diameter of the clamping slot 4 .

[0022] Specifically, by matching the size of the end of the clamping block 6 with the inner diameter of the clamping slot 4, the gap between the clamping block 6 and the clamping slot 4 is reduced, thereby improving the stability of the clamping.

[0023] A plurality of return springs 11 are fixedly mounted on the other side surface of the connecting plate 8 , and one end of the plurality of return springs 11 is fixedly connected to the groove wall of the corresponding mounting groove 7 .

[0024] Specifically, through the cooperation of the reset spring 11 and the gear 10, the reset spring 11 controls the reset of the block 6, and the gear 10 engages with the tooth groove 9 at the top of the block 6, thereby controlling the block 6 to shrink to the inside of the mounting groove 7, ensuring that when the explosion-proof switch body 1 and the T-shaped mounting strip 3 are assembled, the block 6 moves to the inside of the mounting groove 7 to avoid affecting the assembly.

[0025] A rotating ring is fixedly mounted at the end of the extended portion of the rotating rod 5 , and the surface of the rotating ring is provided with evenly distributed anti-skid grooves.

[0026] Specifically, the rotation of the rotating rod 5 is facilitated by the provision of the rotating ring.

[0027] Specifically, when installing the explosion-proof switch body 1, first fix one end of the T-shaped mounting strip 3 with a screw, then manually turn it to the rotating ring, and the rotating rod 5 is driven to rotate by the rotation of the rotating ring, and the gear 10 is driven to rotate by the rotation of the rotating rod 5, and the block 6 is pushed to move toward the inside of the mounting groove 7 by the rotation of the gear 10. At this time, the reset spring 11 is compressed until the block 6 is completely moved into the inside of the mounting groove 7, and then the T-shaped assembly groove 2 on the back of the explosion-proof switch body 1 is interlaced with the T-shaped mounting strip 3, so that the explosion-proof switch body 1 slides on the surface of the T-shaped mounting strip 3. When it slides to the set position, the rotating ring is manually released. At this time, the block 6 is reset by the thrust of the reset spring 11, so that one end of the block 6 is inserted into the slot 4 opened on the side of the T-shaped assembly groove 2, and the installation of the explosion-proof switch body 1 is completed.
