All of them need explosion-proof indicator lights; currently, in the actual use of the explosion-proof indicator lights in the prior art, generally only the bulb position is explosion-proofed. Due to the large explosion power in the coal mining industry and the lack of a shock-absorbing structure on the lamp body, the built-in parts of the lamp body are prone to loosening when it is in a vibrating environment for a long time, which can easily lead to failure of the indicator light and poor contact.

[0003] Therefore, an explosion-proof indicator light is proposed to solve the above problems. Utility Model Content

[0008] Preferably, the mounting member includes a rack embedded in one side of the plug plate, a mounting cavity is opened on one side of the inner cavity of the transverse plate, a gear is rotatably mounted in the inner cavity of the mounting cavity, a rotating rod is rotatably mounted in the inner cavity of the mounting cavity and on one side of the gear, the top of the rotating rod passes through the transverse plate and extends to the top of the transverse plate, a pawl is provided on the surface of the rotating rod, the pawl is engaged with the gear, and a torsion spring is installed on the surface of the rotating rod and on the top of the pawl.

[0012] The beneficial effects of the utility model are:

[0013] 1. When the coal mine blasting is powerful, the force on the lamp body drives the piston cylinder to float up and down along the piston rod. While the piston cylinder floats up and down, the piston plate buffers the lamp body through the reset spring to reduce the vibration of the lamp body caused by the blasting. When the piston plate slides in the inner cavity of the piston cylinder, the piston plate injects the gas inside the piston cylinder into the inner cavity of the airbag through the air pipe, so that the airbag expands and increases its volume, stabilizes the distance between the cross plate and the lamp body, reduces the shaking amplitude of the lamp body, and plays a role in shock reduction of the lamp body, avoiding the loosening of the internal parts of the lamp body when it is shaken for a long time, resulting in poor contact and failure of the lamp body;

[0014] 2. When installing the lamp body, insert the plug plate into the interior of the horizontal plate limit slide groove. When the plug plate is continuously pushed forward, the pawl is moved through the meshing connection between the rack and the gear. When the plug plate is pushed to the bottom of the limit slide groove, the gear is locked through the characteristics of the pawl, which makes it easier to install the lamp body and prevents the plug plate from retreating when the lamp body is shaken, causing the lamp body to fall off.

[0023] like Figure 1 , Figure 2 and Figure 3As shown, the shock absorber 21 includes four piston cylinders 211 installed through the top and bottom of the lamp body 12, a piston plate 212 is slidably installed in the inner cavity of the piston cylinder 211, a return spring 213 is fixedly installed on one side of the piston plate 212, and the bottom end of the return spring 213 is fixedly connected to the bottom of the inner cavity of the piston cylinder 211, and a piston rod 214 is fixedly installed on the other side of the piston plate 212. The top end of the piston rod 214 penetrates the piston cylinder 211 and extends to the outside of the piston cylinder 211, and the end of the piston rod 214 located outside the piston cylinder 211 is fixedly installed with a plug plate 215, and the plug plate 215 penetrates the horizontal plate 11 and is slidably connected to the horizontal plate 11; an air bag 216 is fixedly installed on the top and bottom of the lamp body 12, and the end of the air bag 216 away from the lamp body 12 is fixedly connected to the plug plate 215, and the end of the piston cylinder 211 located inside the lamp body 12 is connected with an air pipe 217, and the end of the air pipe 217 away from the piston cylinder 211 is connected with the air bag 216;

[0024] The lamp body 12 is subjected to force to drive the piston cylinder 211 to float up and down along the piston rod 214. While the piston cylinder 211 floats up and down, the piston plate 212 buffers the lamp body 12 through the return spring 213 to reduce the vibration force of the lamp body 12 caused by the explosion. While the piston plate 212 slides in the inner cavity of the piston cylinder 211, the piston plate 212 injects the gas inside the piston cylinder 211 into the inner cavity of the airbag 216 through the air pipe 217, so that the airbag 216 expands and increases its volume, thereby stabilizing the distance between the horizontal plate 11 and the lamp body 12 and reducing the shaking amplitude of the lamp body 12. Limiting grooves are provided on the adjacent sides of the two horizontal plates 11, and the plug plate 215 passes through the limiting grooves and is slidably connected with the limiting grooves.

[0025] like Figure 1 , Figure 4 and Figure 5 As shown, the mounting member 22 includes a rack 221 embedded in one side of the plug plate 215, a mounting cavity 222 is opened on one side of the inner cavity of the horizontal plate 11, a gear 223 is rotatably mounted in the inner cavity of the mounting cavity 222, a rotating rod 224 is rotatably mounted in the inner cavity of the mounting cavity 222 and on one side of the gear 223, the top of the rotating rod 224 passes through the horizontal plate 11 and extends to the top of the horizontal plate 11, a pawl 225 is arranged on the surface of the rotating rod 224, the pawl 225 is engaged with the gear 223, and a torsion spring 226 is installed on the surface of the rotating rod 224 and on the top of the pawl 225;

When the lamp body 12 needs to be disassembled, the ratchet 225 is rotated to separate from the gear 223 to slide the plug plate 215 out of the interior of the horizontal plate 11.

[0027] When the lamp body 12 is installed, the plug plate 215 is inserted into the interior of the limit slide groove of the horizontal plate 11. When the plug plate 215 is continuously pushed forward, the ratchet 225 is toggled through the meshing connection between the rack 221 and the gear 223. When the plug plate 215 is pushed to the bottom of the limit slide groove, the gear 223 is locked by the characteristics of the ratchet 225. When the coal mine blasting power is large, the lamp body 12 is forced to drive the piston cylinder 211 to float up and down along the piston rod 214, and the piston While the cylinder 211 floats up and down, the piston plate 212 cushions the lamp body 12 through the return spring 213 to reduce the vibration force of the lamp body 12 caused by the explosion, and while the piston plate 212 slides in the inner cavity of the piston cylinder 211, the piston plate 212 injects the gas inside the piston cylinder 211 into the inner cavity of the airbag 216 through the air pipe 217, so that the airbag 216 expands to increase its volume, stabilizes the distance between the cross plate 11 and the lamp body 12, and reduces the shaking amplitude of the lamp body 12.
