[0002] An electrical control cabinet is a metal enclosure used to control electrical equipment. It typically contains circuit breakers, disconnectors, load switches, operating mechanisms, transformers, lightning arresters, busbars, current-carrying conductors, and components and facilities for control, measurement, protection, regulation, and communication. These devices, enclosed within the metal cabinet, form an independent control unit responsible for controlling, directing, regulating, and protecting power distribution, transmission, conversion, and consumption. Electrical control cabinets play a vital role in power systems, ensuring their stable, safe, and efficient operation. Explosion-proof electrical control cabinets are a specialized type of electrical control cabinet, primarily designed for use in flammable and explosive environments, such as those with explosive gases or dust, to ensure the safe operation of electrical equipment and control systems. Explosion-proof electrical control cabinets utilize specialized explosion-proof designs, such as explosion-proof enclosures and explosion-proof electrical components, to prevent potential explosions, such as sparks or high temperatures, during operation. These control cabinets are widely used in flammable and explosive environments, such as the petroleum, chemical, and coal mines, and are crucial for ensuring production safety and reducing accident losses. Explosion-proof shafts are specially designed mechanical components commonly used in equipment requiring explosion-proof environments, such as electrical equipment used in flammable and explosive environments. These shafts offer excellent rust and corrosion resistance, enabling long-term stable operation in harsh working environments, reducing equipment failures and safety hazards caused by corrosion. They play a vital role in explosion-proof electrical control cabinets, ensuring safe and stable operation of motors in hazardous environments and minimizing the risk of accidents.

[0003] In the prior art, when using an explosion-proof shaft, during the actual installation process, when the explosion-proof electrical control cabinet door is closed, assembly errors are likely to occur between the shaft and the corresponding hole inside the cabinet. Therefore, in order to solve the above problem, a quick-release and quick-install explosion-proof shaft assembly is proposed. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a quick-disassembly and quick-installation explosion-proof shaft assembly, comprising an explosion-proof housing, an explosion-proof shaft sleeve, an explosion-proof shaft body, a handle, a limit spring, a retaining ring, a spring, an internal mechanism and a shaft hole;

[0006] An explosion-proof sleeve is fixedly installed on the inner side of the explosion-proof shell, an explosion-proof shaft body is movably connected to the inner side of the explosion-proof sleeve, a handle is fixedly connected to the surface of the explosion-proof shaft body, a limiting retaining spring is fixedly connected to the surface of the explosion-proof shaft body, a retaining ring is fixedly connected to the surface of the retaining ring, a spring is fixedly connected to the surface of the retaining ring, an internal mechanism is provided on the inner side of the explosion-proof shell, and an axis hole is opened on the surface of the internal mechanism.

[0007] Preferably, the explosion-proof rotating shaft body is connected to the handle outside the explosion-proof shell through an explosion-proof shaft sleeve, and the explosion-proof rotating shaft body and the retaining ring are movably connected.

[0008] Preferably, one end of the spring is fixedly connected to the limit spring, and the other end of the spring is fixedly connected to the retaining ring.

[0009] Preferably, the internal mechanism is fixedly mounted on the inner side of the explosion-proof housing, and the explosion-proof rotating shaft body is plug-fitted into the shaft hole.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] When closing the explosion-proof shell, the handle is pulled first to enable the handle to drive the explosion-proof shaft body to move. After the explosion-proof shell is completely closed, the handle is released, so that the explosion-proof shaft body can be reset under the action of the spring and inserted into the shaft hole, so that the assembly of the explosion-proof shaft body and the shaft hole is not prone to misalignment.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-4 , an embodiment provided by the utility model:

[0019] A quick-release, quick-install explosion-proof shaft assembly includes an explosion-proof housing 1, an explosion-proof shaft sleeve 11, an explosion-proof shaft body 12, a handle 13, a limit spring 14, a retaining ring 15, a spring 16, an internal mechanism 17, and a shaft hole 18. The explosion-proof housing 1 can prevent and control explosion risks, ensuring that electrical equipment and control systems can operate safely in flammable and explosive environments.

[0020] An explosion-proof sleeve 11 is fixedly installed on the inner side of the explosion-proof shell 1, and an explosion-proof shaft body 12 is movably connected to the inner side of the explosion-proof sleeve 11. A handle 13 is fixedly connected to the surface of the explosion-proof shaft body 12, and a limited retaining spring 14 is fixedly connected to the surface of the explosion-proof shaft body 12. A retaining ring 15 is fixedly connected to the surface of the explosion-proof sleeve 11, and a spring 16 is fixedly connected to the surface of the retaining ring 15. An internal mechanism 17 is provided on the inner side of the explosion-proof shell 1, and an axis hole 18 is provided on the surface of the internal mechanism 17. When the handle 13 is pulled, the explosion-proof shell 1 is installed and tightened. After it is tightened in place, the handle 13 is loosened and the explosion-proof shaft body 12 is slowly reset under the action of the spring 16, so that the explosion-proof shaft body 12 can be inserted into the axis hole 18, thereby facilitating the installation of the explosion-proof shaft body 12. At the same time, the explosion-proof shaft body 12 and the axis hole 18 are not prone to assembly errors.

[0021] Furthermore, the explosion-proof shaft body 12 is connected to the handle 13 outside the explosion-proof shell 1 through the explosion-proof sleeve 11, and the explosion-proof shaft body 12 and the retaining ring 15 are movably connected. By pulling the handle 13, the explosion-proof shaft body 12 can be moved inside the explosion-proof sleeve 11 and the retaining ring 15, and then by loosening the handle 13, the explosion-proof shaft body 12 can be reset under the rebound action of the spring 16, so that when the explosion-proof shaft body 12 is installed, the explosion-proof shaft body 12 is easier to fit into place with the shaft hole 18.

[0022] Furthermore, one end of the spring 16 is fixedly connected to the limit spring 14, and the other end of the spring 16 is fixedly connected to the retaining ring 15. Through the setting of the spring 16, the explosion-proof shaft body 12 can be reset, and the explosion-proof shaft body 12 can be reset and the shaft hole 18 can be inserted, thereby facilitating the installation of the explosion-proof shaft body 12.

[0023] Furthermore, the internal mechanism 17 is fixedly installed on the inner side of the explosion-proof shell 1, and the explosion-proof shaft body 12 and the shaft hole 18 are plugged into each other. By opening the shaft hole 18, when the explosion-proof shaft body 12 and the shaft hole 18 are plugged into each other, the installation of the explosion-proof shaft body 12 can be completed, thereby ensuring the safety of the electrical control cabinet.

[0024] Working principle: During use, when the explosion-proof shell 1 is ready to be installed and tightened, the handle 13 is pulled, and the explosion-proof shaft body 12 will move on the inner side of the explosion-proof sleeve 11 and then the retaining ring 15 under the action of the handle 13. At this time, the spring 16 is in a contracted state, and the explosion-proof shell 1 is installed and tightened at the same time. After tightening into place, release the handle 13, and the explosion-proof shaft body 12 will slowly reset under the rebound action of the spring 16, thereby realizing the insertion of the explosion-proof shaft body 12 into the shaft hole 18, thereby completing the installation of the explosion-proof shaft body 12.

[0025] The above are only preferred embodiments of the present invention and do not constitute any form of limitation to the present invention. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of protection of the technical solution of the present invention.
