Description

Technical Field

[0001] This utility model belongs to the technical field of explosion-proof sealing joints, and specifically relates to a quick-disassembly explosion-proof sealing joint. Background Technology

[0002] The main functions of explosion-proof sealing joints are to fix the position, prevent pipeline leakage, and isolate explosions, thereby ensuring safe use in flammable and explosive environments.

[0003] Currently, Chinese utility model patent CN221886012U discloses an explosion-proof sealing joint. Existing explosion-proof sealing joints using a plug-in connection method are relatively unstable, therefore threaded connections are often used. However, when bolting multiple screws, only sequential rotation of the screws is possible, making synchronous rotation impossible and resulting in low efficiency for both installation and disassembly. Furthermore, existing explosion-proof sealing joints typically use rubber rings for sealing. While the rubber rings offer some localized elasticity for effective sealing after installation, their elasticity decreases over time, preventing a tight fit and allowing gaps to form between the rubber rings, thus reducing the sealing performance of the explosion-proof sealing joint. Utility Model Content

[0004] The purpose of this invention is to provide a quick-disassembly explosion-proof sealing joint, which has the advantages of facilitating quick disassembly and assembly of the explosion-proof sealing joint and improving the sealing performance of the explosion-proof sealing joint.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a quick-disassembly explosion-proof sealing joint, including a female joint and a male joint, wherein the female joint has a threaded hole on the side near the male joint, a rotating ring is slidably sleeved on the surface of the male joint, and an annular rack is bolted to the inner surface of the rotating ring. The male joint is rotatably connected to a mounting screw that is threaded into the threaded hole on the side near the female joint, and a first gear that meshes with the annular rack is welded to the end of the mounting screw away from the threaded hole.

[0006] The above technical solution involves direct installation of the female and male connectors via mounting screws and threaded connections. Multiple mounting screws are then simultaneously rotated to engage with the threaded holes. This allows for rapid installation and disassembly of the female and male connectors, eliminating the need to rotate the mounting screws individually and improving efficiency. During installation, the explosion-proof housing slides against the surface of the connection point, providing explosion-proof protection. Simultaneously, as the housing slides, it engages with the first and second rubber rings of the male and female connectors, ensuring a tight seal even with insufficient elasticity, guaranteeing the airtightness of the explosion-proof sealing joint.

[0007] The present invention is further configured such that: a plug is welded to the side of the female connector near the male connector; the mounting screws are arranged in annular array on the surface of the plug; a sliding connector that engages with the plug is provided inside the female connector near the male connector; an explosion-proof shell is slidably fitted onto the outer surface of the female connector; a second gear is rotatably connected to the inner wall of the female connector; a straight rack that meshes with the second gear is welded to the outer surface of the sliding connector and the inner surface of the explosion-proof shell; a first rubber ring that cooperates with each other is snapped onto the side of the explosion-proof shell and the male connector that are close to each other; and a second rubber ring that cooperates with each other is snapped onto the side of the explosion-proof shell away from the first rubber ring and the surface of the female connector.

[0008] By adopting the above technical solution, the first and second rubber rings are driven to abut against and fix the first and second rubber rings between the male and female connectors, respectively. In this way, even if the elasticity is insufficient, it can be made to fit tightly by pushing force, thus ensuring the sealing performance of the explosion-proof sealing joint.

[0009] The present invention is further configured such that: both sides of the surface of the rotating ring are fitted with sealing rings that are slidably connected to the female connector.

[0010] By adopting the above technical solution, the sealing between the rotating ring and the female connector is improved, preventing external moisture and dust from entering the interior.

[0011] The present invention is further configured such that the outer surface of the rotating ring is provided with anti-slip texture.

[0012] By adopting the above technical solution, the surface friction is increased, making rotation adjustment easier.

[0013] The present invention is further configured such that: the female connector has a limiting groove that is slidably connected to the sliding connector inside.

[0014] The above technical solution is used to limit the sliding of the sliding joint inside the female joint, thereby improving the stability of linear sliding.

[0015] The present invention is further configured such that: a return spring is bolted to the end of the sliding joint away from the plug and fixedly connected to the inside of the female joint.

[0016] Using the above technical solution, after the sliding connector is pushed into the female connector by the plug, the return spring can be squeezed to generate a rebound force. Thus, after the plug is pulled out, the sliding connector can be automatically reset by the rebound force of the return spring, which will drive the explosion-proof shell to retract to the surface of the female connector.

[0017] The present invention is further configured such that: an isolation sleeve that is slidably connected to the plug is welded inside the female connector, and the sliding connector is slidably sleeved on the surface of the isolation sleeve.

[0018] By adopting the above technical solution, after the female and male connectors are plugged into each other, the insulating sleeve and the plug are sealed together to prevent the gas or liquid being transported from seeping into the interior of the female connector and causing any impact.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. The female and male connectors are installed by directly connecting them with the threaded holes using mounting screws. Multiple mounting screws are then rotated synchronously to engage with the threaded holes. This allows for quick installation and disassembly of the female and male connectors, eliminating the need to rotate each mounting screw individually and improving efficiency.

[0021] 2. During installation, the explosion-proof housing slides onto the surface of the connection between the female and male connectors to provide explosion-proof protection. Simultaneously, as the housing slides, it causes the first and second rubber rings to abut and fix against the first and second rubber rings of the male and female connectors, respectively. This ensures a tight seal even if the elasticity is insufficient, guaranteeing the airtightness of the explosion-proof sealing joint. Attached Figure Description

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Example 1:

[0028] refer to Figure 1 , Figure 2 , Figure 3An explosion-proof sealing joint for quick assembly and disassembly includes a female connector 1 and a male connector 2. The female connector 1 has a threaded hole 7 on the side near the male connector 2. A rotating ring 3 is slidably fitted onto the surface of the male connector 2. A ring-shaped rack 4 is bolted to the inner surface of the rotating ring 3. A mounting screw 6, threaded into the threaded hole 7, is rotatably connected to the side of the male connector 2 near the female connector 1. A first gear 5, meshing with the ring-shaped rack 4, is welded to the end of the mounting screw 6 away from the threaded hole 7. The female connector 1 and male connector 2 are directly connected by the mounting screw 6 and the threaded hole 7 for installation. Then, multiple mounting screws 6 are simultaneously rotated to engage with the threaded holes 7. This allows for quick assembly and disassembly of the female connector 1 and male connector 2 without having to rotate each mounting screw 6 individually, improving assembly and disassembly efficiency.

[0029] refer to Figure 2 Both sides of the rotating ring 3 are fitted with sealing rings 15 that are slidably connected to the female connector 1. This improves the sealing between the rotating ring 3 and the female connector 1, preventing external moisture and dust from entering the interior.

[0030] refer to Figure 1 The outer surface of the rotating ring 3 is provided with anti-slip texture 16. This increases surface friction and facilitates rotation adjustment.

[0031] Brief description of the usage process: By aligning the female connector 1 and male connector 2, the mounting screw 6 is aligned with the threaded hole 7 inside the female connector 1. Then, rotating the rotating ring 3 drives the ring rack 4 to mesh with the first gear 5, thereby synchronously driving the mounting screw 6 at one end of the male connector 2 to rotate in the same direction. After the mounting screw 6 engages with the threaded hole 7, it is inserted into the threaded hole 7, thus quickly installing the female connector 1 and male connector 2 together. Simultaneously, by rotating the rotating ring 3 in the opposite direction, the mounting screw 6 rotates synchronously in the opposite direction, thereby moving the mounting screw 6 out of the threaded hole 7, allowing the female connector 1 and male connector 2 to be quickly disassembled.

[0032] Example 2:

[0033] refer to Figure 1 , Figure 2A quick-assembly and disassembly explosion-proof sealing joint is disclosed. A plug 8 is welded to the side of the female connector 1 near the male connector 2. A ring of mounting screws 6 is arranged on the surface of the plug 8. A sliding connector 9, which engages with the plug 8, is located inside the female connector 1 near the male connector 2. An explosion-proof housing 10 is slidably fitted onto the outer surface of the female connector 1. A second gear 11 is rotatably connected to the inner wall of the female connector 1. Linear racks 12, meshing with the second gear 11, are welded to the outer surface of the sliding connector 9 and the inner surface of the explosion-proof housing 10. First rubber rings 13 are engaged with each other on the sides of the explosion-proof housing 10 and the male connector 2 that are close to each other. Second rubber rings 14 are engaged with each other on the side of the explosion-proof housing 10 away from the first rubber ring 13 and on the surface of the female connector 1. When the female connector 1 and the male connector 2 are connected and installed, the explosion-proof housing 10 slides onto the surface of the connection between the female connector 1 and the male connector 2 to provide explosion-proof protection. At the same time, when the explosion-proof housing 10 slides, it drives the first rubber ring 13 and the second rubber ring 14 to abut and fix with the first rubber ring 13 and the second rubber ring 14 between the male connector 2 and the female connector 1, respectively. In this way, even if the elasticity is insufficient, it can be made to fit tightly by pushing force, so as to ensure the sealing performance of the explosion-proof sealing joint.

[0034] refer to Figure 2 The female connector 1 has a limiting groove 17 inside, which slides and connects with the sliding connector 9. This groove is used to limit the sliding of the sliding connector 9 inside the female connector 1, thereby improving the stability of linear sliding.

[0035] refer to Figure 2 The end of the sliding connector 9 furthest from the plug 8 is bolted with a return spring 18 that is fixedly connected to the inside of the female connector 1. After the sliding connector 9 is pushed into the female connector 1 by the plug 8, it can squeeze the return spring 18 to generate a rebound force. Thus, after the plug 8 is pulled out, the sliding connector 9 can automatically reset by the rebound force of the return spring 18, driving the explosion-proof housing 10 to retract to the surface of the female connector 1.

[0036] refer to Figure 2 The female connector 1 has an insulating sleeve 19 welded inside, which is slidably connected to the plug 8. The sliding connector 9 is slidably fitted onto the surface of the insulating sleeve 19. After the female connector 1 and the male connector 2 are inserted into each other, the insulating sleeve 19 and the plug 8 form a sealing contact, thereby preventing the gas or liquid being transported from seeping into the interior of the female connector 1 and causing any impact.

[0037] Brief description of the usage process: When the female connector 1 and male connector 2 are plugged together, the male connector 2 drives the plug 8 to be inserted into the female connector 1, causing the plug 8 to push the sliding connector 9 into the female connector 1. Then, the sliding connector 9 meshes with the linear rack 12 and the second gear 11, thereby causing the explosion-proof housing 10 to slide in the opposite direction to the sliding connector 9 on the surface of the female connector 1. This allows the explosion-proof housing 10 to be fitted onto the surface of the connection between the female connector 1 and the male connector 2 for explosion-proof protection. At the same time, when the explosion-proof housing 10 slides, it causes the first rubber ring 13 and the second rubber ring 14 to abut and fix against the first rubber ring 13 and the second rubber ring 14 between the male connector 2 and the female connector 1, respectively, ensuring a tight fit and sealing.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
