[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1 - Figure 3 The utility model provides an embodiment: an outer cover plate of a flame arrester that is easy to disassemble, including an upper cover plate 1, a lower cover plate 2 is arranged at the bottom end of the upper cover plate 1, and a fireproof net is arranged on the inner walls of the upper cover plate 1 and the lower cover plate 2, and a positioning pin 3 is fixedly connected to the bottom end of the upper cover plate 1, and a positioning hole 4 is opened near the bottom end of the lower cover plate 2 near the positioning pin 3. The upper cover plate 1 and the lower cover plate 2 are limited by the cooperation of the positioning pin 3 and the positioning hole 4. A disassembly component is arranged on the inner wall of the top end of the lower cover plate 2, and the disassembly component includes a rotating circle 51, and the outer wall of the bottom end of the rotating circle 51 is rotatably connected to the inner wall of the top end of the lower cover plate 2, and the top end of the rotating circle 51 is fixedly connected to a limiting buckle 53, and the limiting buckle 53 is provided with multiple groups, which can be used in conjunction with a card block 55 to limit the upper cover plate 1.

[0033] Reference Figure 3 - Figure 5The bottom side of the front end of the rotating circle 51 is rotatably connected with a moving block 52. Through the movement of the moving block 52, the rotating circle 51 is driven to slide on the inner wall of the top end of the lower cover plate 2. A card slot 54 is opened at the bottom end of the upper cover plate 1 near the top of the rotating circle 51. The outer wall of the top end of the rotating circle 51 slides on the inner wall of the card slot 54, which improves the stability of the movement of the rotating circle 51. The inner wall of the card slot 54 is fixedly connected with a card block 55. There are multiple groups of card blocks 55, and the number is the same as that of the limiting buckles 53. The inner side of the limiting buckle 53 slides on the outer side of the card block 55 to limit the card block 55. At the same time, the lower side of the limiting buckle 53 is used to The inclined surface makes the block 55 have a downward force, thereby improving the stability of the upper cover 1. The lower cover 2 is rotatably connected to the right side of the moving block 52 with a stabilizing block 56, and the inner wall of the stabilizing block 56 is rotatably connected to the threaded rod 57. The moving block 52 is driven to slide and rotate in the guide groove 58 through the threads on the threaded rod 57, and at the same time drives the stabilizing block 56 and the moving block 52 to be in parallel planes. The left side of the threaded rod 57 is threadedly connected to the inner wall of the moving block 52. The lower cover 2 is provided with a guide groove 58 near the bottom of the rotating circle 51 for guiding the moving block 52.

[0034] Reference Figure 1 , Figure 5 and Figure 6 , a sealing component is provided on the inner wall at the top of the lower cover plate 2, and the sealing component includes a sealing gasket 61, which is set to be made of silicone rubber. Silicone rubber has good elasticity, high and low temperature resistance, corrosion resistance and other characteristics. The outer wall of the bottom end of the sealing gasket 61 is slidably connected to the inner wall of the lower cover plate 2. The sealing gasket 61 and the lower cover plate 2 are elastically connected by a compression spring 62 to ensure that the sealing gasket 61 always maintains close contact with the sealing groove 63 of the upper cover plate 1, thereby ensuring the sealing effect. The upper cover plate 1 is provided with a sealing groove 63 near the top of the sealing gasket 61. In order to cooperate with the sealing gasket 61 to form a complete sealing structure, the outer wall of the top end of the sealing gasket 61 slides on the inner wall of the sealing groove 63. When the upper cover plate 1 and the lower cover plate 2 are closed, the outer wall of the top end of the sealing gasket 61 will slide into and fit tightly on the inner wall of the sealing groove 63, thereby achieving a sealing effect. A plurality of groups of compression springs 62 are provided, and the plurality of groups of compression springs 62 are evenly distributed at the center point of the lower cover plate 2, which can ensure that the sealing gasket 61 can be evenly deformed when subjected to pressure to avoid damage or poor sealing caused by excessive local force.

[0035] Working principle: When in use, when it is necessary to disassemble the outer cover of the flame arrester, first turn the handle to drive the threaded rod 57 to rotate on the inner wall of the moving block 52, and drive the moving block 52 to move along the guide groove 58 through the thread. At the same time, the stabilizing block 56 is driven to rotate through the threaded rod 57, so that the rotating circle 51 rotates on the inner wall of the lower cover 2, driving the multiple groups of limit buckles 53 to release the restrictions on the multiple groups of card blocks 55, thereby releasing the restrictions on the upper cover 1. At this time, pull the upper cover 1 upward and slide the locating pin 3 out of the inner wall of the locating hole 4, and the disassembly of the outer cover of the flame arrester is completed. When installing the outer cover of the flame arrester, the upper cover 1 squeezes the lower cover 2 to make the sealing gasket 61 slide into the inner wall of the sealing groove 63, and the sealing gasket 61 is tightly attached to the inner wall of the sealing groove 63 through the elastic force of the multiple groups of compression springs 62 and the downward pressure of the upper cover 1, thereby ensuring the sealing of the device and improving the stability of the overall structure.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
