[0030] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0031] Reference Figures 1 to 4This application provides a high-sealing explosion-proof door with a double-sealing structure, including an explosion-proof door body 1. A sealing component 2 is fixedly installed on one side of the explosion-proof door body 1, a reinforcing component 3 is provided on one side of the explosion-proof door body 1, and a labor-saving component 5 is fixedly connected to one side of the explosion-proof door body 1. The reinforcing component 3 includes a sliding groove 31 and a snap-fit ​​bracket 32. The sliding groove 31 is formed on one side of the explosion-proof door body 1, and the snap-fit ​​bracket 32 ​​is slidably connected to one side of the sliding groove 31. A spring 33 is fixedly connected to one side of the snap-fit ​​bracket 32, and a handle 34 is provided on one side of the snap-fit ​​bracket 32. A slot 35 is formed on one side of the handle 34, and the snap-fit ​​bracket 32 ​​and the slot 35 are snapped together. The reinforcing component 3 also includes a mounting plate 3. 7 and bolt 38, mounting plate 37 are respectively fixedly installed on both sides of handle 34. Bolt 38 is threaded to one side of mounting plate 37. Explosion-proof door body 1 has a screw hole 39 on one side. Bolt 38 and screw hole 39 are connected by threads. Reinforcing component 3 also includes anti-slip sleeve 36, which is set on the side wall of handle 34. Sealing component 2 includes sealing plate 21 and sealing gasket 22. Sealing plate 21 is fixedly installed on one side of explosion-proof door body 1. Sealing gasket 22 is set on one side of sealing plate 21. Sealing gasket 23 is set on one side of sealing plate 21. Two hinges 4 are fixedly installed on one side of explosion-proof door body 1, and the two hinges 4 are arranged opposite each other.

[0032] In this embodiment, when the reinforcement component 3 is needed to reinforce the explosion-proof door body 1, first grasp the handle 34 with the anti-slip sleeve and push the handle 34 towards the explosion-proof door body 1. At this time, the slot 35 on one side of the handle 34 will engage with the locking bracket 32 ​​slidably connected to the side of the slide groove 31. The locking bracket 32 ​​is connected to the spring 33. During the pushing process, the spring 33 will be compressed. When the slot 35 and the locking bracket 32 ​​are engaged, the elastic force of the spring 33 can play a certain stabilizing role. Then, tighten the bolts 38 on the mounting plates 37 on both sides of the handle 34. The handle 34 is firmly fixed in the screw hole 39 on one side of the explosion-proof door body 1, which further enhances the reinforcement effect, prevents the door from being opened accidentally, and ensures the stability of the explosion-proof door body 1. As for the sealing component 2, the sealing plate 21 is fixedly installed on one side of the explosion-proof door body 1, and the sealing gasket 22 and sealing gasket 23 are located on both sides of the sealing plate 21. When the explosion-proof door is closed, the sealing gasket 22 and sealing gasket 23 will fit tightly against the door frame. Through this double sealing structure, the external gas and other substances are effectively blocked, which greatly improves the sealing performance of the explosion-proof door and enables it to better perform its explosion-proof function.

[0033] Reference Figures 1 to 4In one aspect of this embodiment, the labor-saving component 5 includes a circular block 51 and a screw hole 52. The circular block 51 is fixedly connected to one side of the explosion-proof door body 1. The screw hole 52 is opened at one end of the circular block 51. A crank handle 53 is provided on one side of the circular block 51. A screw rod 54 is fixedly connected to one end of the crank handle 53. The screw rod 54 and the screw hole 52 are connected by threads. The labor-saving component 5 also includes an anti-slip sleeve 55, which is provided on one side of the crank handle 53.

[0034] In this embodiment, for the labor-saving component 5, when opening or closing the explosion-proof door body 1, the crank 53 with the anti-slip sleeve 55 is held and rotated. The screw 54 fixed at one end of the crank 53 is connected to the screw hole 52 on the circular block 51 by thread. When the crank 53 is rotated, the screw 54 will move in the screw hole 52. With the help of the transmission action of the thread, the opening or closing operation of the explosion-proof door can be achieved with relatively little effort.

[0035] Working principle: When it is necessary to use the reinforcement component 3 to reinforce the explosion-proof door body 1, first hold the handle 34 with the anti-slip sleeve and push the handle 34 towards the explosion-proof door body 1. At this time, the slot 35 on one side of the handle 34 will engage with the locking bracket 32 ​​that is slidably connected to the side of the slide groove 31. The locking bracket 32 ​​is connected to the spring 33. During the pushing process, the spring 33 will be compressed. When the slot 35 and the locking bracket 32 ​​are engaged, the elasticity of the spring 33 can play a certain stabilizing role. Then, through the bolts 38 installed on the mounting plates 37 on both sides of the handle 34, screw the bolts 38 into the corresponding screw holes 39 on one side of the explosion-proof door body 1, so that the handle 34 is firmly fixed, further enhancing the reinforcement effect, preventing the door from being opened accidentally, and ensuring the stability of the explosion-proof door body 1.

[0036] For the labor-saving component 5, when opening or closing the explosion-proof door body 1, the crank 53 with the anti-slip sleeve 55 is held and rotated. The screw 54 fixed at one end of the crank 53 is connected to the screw hole 52 on the circular block 51 by thread. When the crank 53 is turned, the screw 54 will move in the screw hole 52. With the help of the transmission action of the thread, the opening or closing operation of the explosion-proof door can be achieved with relatively little effort. As for the sealing component 2, the sealing plate 21 is fixedly installed on one side of the explosion-proof door body 1, and the sealing gasket 22 and sealing gasket 23 are located on both sides of the sealing plate 21 respectively. When the explosion-proof door is closed, the sealing gasket 22 and sealing gasket 23 will fit tightly against the door frame. Through this double sealing structure, the external gas and other substances are effectively blocked, which greatly improves the sealing performance of the explosion-proof door and enables it to better perform its explosion-proof function.
