Description

Technical Field

[0001] This utility model belongs to the field of explosion-proof signal light technology, specifically referring to an explosion-proof signal light device. Background Technology

[0002] Explosion-proof signal lights are widely used in hazardous environments such as petroleum, chemical, and coal mines where flammable and explosive gases or dust exist, and their explosion-proof performance is directly related to production safety. In existing technologies, to facilitate maintenance and replacement, explosion-proof signal lights often adopt a detachable structure. For example, the explosion-proof signal light disclosed in publicly authorized patent CN202323443475.1, which reduces maintenance costs, allows for the disassembly of the lamp cover and base through components such as pull plates, movable rods, and insertion rods.

[0003] However, this structure has obvious defects: the pull plates are distributed around the signal light, and multiple pull plates need to be pulled at the same time to disassemble the plug rod from the socket. This makes it difficult for a single person to operate, and it is difficult to apply force at the same time in confined spaces or when working at heights, which makes the installation and disassembly process cumbersome and prolongs the maintenance time. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides an explosion-proof signal light device, which effectively solves the problem of difficulty in applying force simultaneously, resulting in a complicated installation and disassembly process.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: An explosion-proof signal light device includes a mounting base, in which a signal light body is fixedly installed. The signal light body is covered with a detachable explosion-proof cover. A sealing plate is provided on the outer side of the bottom of the explosion-proof cover, and a docking ring is provided on the inner side of the bottom. A docking groove adapted to the docking ring is provided on the top of the mounting base. At least two symmetrically distributed connecting rods slide through the side wall of the docking groove. An end block is fixed at the outer end of the connecting rod, and an L-shaped clamping plate is fixed at the inner end. The clamping plate is wedge-shaped on one side at the top. A clamping groove adapted to the clamping plate is provided on the inner side of the docking ring. A spring is connected between the clamping plate and the inner wall of the mounting base.

[0006] A push ring is slidably sleeved on the outer side of the mounting base. The inner cross section of the push ring is an inclined surface, and the bottom of the end block is arc-shaped and abuts against the inclined surface of the push ring.

[0007] Preferably, the inclination angle of the inner section of the push ring is adapted to the radius of curvature of the arc surface of the end block.

[0008] Preferably, the mounting base has a wiring port on its side wall that communicates with the inside of the mounting base, and the push ring can be adsorbed and fixed on the outer wall of the wiring port.

[0009] Preferably, the bottom of the sealing plate is provided with limit posts at equal intervals, and the top of the mounting base is provided with a limit groove corresponding to the limit posts.

[0010] Preferably, there are four clamping plates, which are evenly distributed along the circumference of the docking groove, and the spring is a tension spring, in which the clamping plates extend into the docking groove under natural conditions.

[0011] Preferably, the contact surface between the sealing plate and the mounting base is provided with an annular silicone sealing strip.

[0012] Compared with the prior art, the present invention achieves the following beneficial effects by adopting the above-mentioned structure: Through the automatic engagement structure of the card plate and the card slot, when installing the explosion-proof cover, it is only necessary to push the docking ring into the docking slot, and the card plate can be automatically engaged into the card slot under the action of the spring to complete the fixation. When disassembling, it is only necessary to push the push ring, and all the card plates can be driven out of the card slot synchronously through the inclined plane transmission, which can quickly remove the explosion-proof cover and solve the problem of the need for synchronous operation of traditional multi-plate pullers.

The utility model will be further described in detail below with reference to the accompanying drawings.

[0021] like Figure 1-5 As shown, the present invention proposes an explosion-proof signal light device, including a mounting base 1, a signal light body 2 fixedly mounted inside the mounting base 1, a detachable explosion-proof cover 3 covering the signal light body 2, the explosion-proof cover 3 being made of transparent PC material, a sealing plate 4 being provided on the outer side of the bottom of the explosion-proof cover 3, and a docking ring 5 being provided on the inner side of the bottom; an annular silicone sealing strip is provided on the contact surface between the sealing plate 4 and the mounting base 1 to ensure the sealing between the protective cover and the mounting base 1, a docking groove 6 adapted to the docking ring 5 is provided on the top of the mounting base 1, at least two symmetrically distributed connecting rods 7 slidingly through the side wall of the docking groove 6, the connecting rods 7 and the side wall of the docking groove 6 being relatively sealed, an end block 8 being fixed on the outer end of the connecting rod 7, and an L-shaped clamping plate 9 being fixed on the inner end, the clamping plate 9 being wedge-shaped on one side at the top, a clamping groove 10 adapted to the clamping plate 9 being provided on the inner side of the docking ring 5, and a spring 11 connecting the clamping plate 9 and the inner wall of the mounting base 1;

[0022] like Figure 1 , 2 As shown in Figure 5, a push ring 12 is slidably sleeved on the outer side of the mounting base 1. The inner cross section of the push ring 12 is an inclined surface. The bottom of the end block 8 is arc-shaped and abuts against the inclined surface of the push ring 12. Pushing the push ring 12 squeezes the end block 8, causing the connecting rod 7 and the clamping plate 9 to move, moving the clamping plate 9 out of the clamping slot 10, and removing the explosion-proof cover 3. The inclination angle of the inner cross section of the push ring 12 is adapted to the radius of curvature of the arc surface of the end block 8. The side wall of the mounting base 1 is provided with a wiring port 13 connected to the inside of the mounting base 1. The push ring 12 can be adsorbed and fixed on the outer wall of the wiring port 13. A permanent magnet is provided on the inner side of the push ring 12. An adsorption seat made of ferromagnetic material is provided on the outer wall of the wiring port 13. The push ring 12 is magnetically adsorbed and fixed on the adsorption seat, fixing the position of the push ring 12.

[0023] like Figure 4 As shown, the bottom of the sealing plate 4 is provided with limit posts 14 at equal intervals, and the top of the mounting base 1 is provided with a limit groove 15 corresponding to the limit posts 14. The limit posts 14 are inserted into the limit groove 15 to initially limit the explosion-proof cover 3.

[0024] like Figure 2As shown, there are 4 clamping plates 9, which are evenly distributed around the circumference of the docking groove 6. Each clamping plate 9 is connected to the inner wall of the mounting base 1 by an independent spring 11. The spring 11 is a tension spring 11. In its natural state, the clamping plate 9 extends into the docking groove 6.

[0025] In practical use, when installing the explosion-proof cover 3, hold the explosion-proof cover 3 and align the bottom docking ring 5 with the docking groove 6 on the top of the mounting base 1, align the limiting post 14 with the limiting groove 15, and face the sealing plate 4 towards the top surface of the mounting base 1. Ensure that the central axis of the docking ring 5 and the docking groove 6 are coincident. Slowly push the docking ring 5 into the docking groove 6. The inner wall of the docking ring 5 presses against the wedge-shaped top of the clamping plate 9, forcing the clamping plate 9 to move the connecting rod 7 inward. The spring 11 is stretched. When the docking ring 5 is fully inserted into the docking groove 6 (the sealing plate 4 is in contact with the top surface of the mounting base 1, and the bottom of the docking ring 5 is in contact with the bottom of the docking groove 6), the clamping plate 9 and the clamping groove 10 are in the same position. The spring 11 returns to its original position and pulls the clamping plate 9 to move. The clamping plate 9 automatically engages with the clamping groove 10, and the explosion-proof cover 3 is limited and fixed. The installation is complete.

[0026] When disassembling the explosion-proof cover 3, push the push ring 12 along the axis of the mounting base 1 towards the signal light direction. The inclined surface squeezes the end block 8, causing the connecting rod 7 and the clamping plate 9 to move inward. The clamping plate 9 disengages from the clamping groove 10. While maintaining the pushing force of the push ring 12, pull the explosion-proof cover 3 upward. The docking ring 5 disengages from the docking groove 6, completing the disassembly. Release the push ring 12, and the spring 11 resets, causing the clamping plate 9 to retract. The push ring 12 is then re-adsorbed and fixed to the outer wall of the wiring port 13.

[0027] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
