[0001] This utility model relates to the field of explosion-proof control box technology, specifically a combined explosion-proof control box. Background Technology

[0002] An explosion-proof control box is an electrical control device specifically designed for flammable and explosive environments. Its main function is to ensure the safe operation of electrical systems in these hazardous environments. Through a special explosion-proof structural design, the explosion-proof control box can effectively isolate internal electrical components from direct contact with the external flammable and explosive environment, preventing explosions caused by electrical sparks, arcs, etc. In the existing technology, the authorized publication number CN... 215222776U proposes a modular explosion-proof control box, comprising: a box body, the bottom of which is welded with a lower frame, and a door engaged with the front end of which is engaged with a door; a connecting mechanism, comprising a first limiting block and a first tension spring, the inner side of which is connected to a first tension spring for resetting; a mounting block, the inner side of which is slidably connected to a fixing rod, and the inner side of which is connected to a second tension spring for resetting, the rear side of which is engaged with the inner side of the second limiting block; and a connecting pipe, which passes through the interior of the box body, with the connecting pipe installed through the interior of the right side of the box body. Although this design allows for the combination of multiple explosion-proof control boxes, when the explosion-proof control boxes are not assembled, the assembled components on the surface of the explosion-proof control boxes are directly exposed, affecting the appearance of the explosion-proof control boxes. Moreover, prolonged exposure can damage the assembled components, affecting the combination between the explosion-proof control boxes. Utility Model Content

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This embodiment provides a technical solution: a combined explosion-proof control box, including an explosion-proof control box body 1, which provides space for the installation of control electrical appliances. The front end of the explosion-proof control box body 1 has an open structure, which facilitates the installation of control electrical appliances inside the explosion-proof control box body 1. An explosion-proof door 2 is provided on the front surface of the explosion-proof control box body 1 to seal the front end of the explosion-proof control box body 1. Both the explosion-proof control box body 1 and the explosion-proof door 2 are made of special aluminum alloy material, which is lightweight, high strength and impact resistant, and has good explosion-proof effect. It also includes a combination mechanism 3.

[0021] The assembly mechanism 3 includes a storage slot 31, a connecting plate 32, a support plate 33, a pin 34, a sliding groove 35, and a baffle 36. The storage slots 31 are respectively located on the sides of the explosion-proof control box 1. Each storage slot 31 has two connecting plates 32 longitudinally slidably connected inside. The inner walls of each storage slot 31 are provided with support plates 33, and the surfaces of the support plates 33 are provided with pins 34. The pins 34 are fitted with insertion holes on the surfaces of the connecting plates 32. The top walls of each storage slot 31 are provided with sliding grooves 35, and the interiors of each sliding groove 35 are vertically slidably connected with elastically limited baffles 36. When assembly is not required, the connecting plates 32 are located inside the storage slots 31, and the baffles 36 seal the openings of the storage slots 31, preventing direct exposure of the assembled components and improving the appearance of the explosion-proof control box. When assembly is required... During assembly, the connecting plate 32 is rotated to a horizontal position and inserted into the storage slot 31 of other explosion-proof control boxes. The movement of the connecting plate 32 allows the insertion holes on its surface to connect with the insertion posts 34 in the storage slots 31 of other explosion-proof control boxes, thus assembling the explosion-proof control boxes. Rotary posts 4 are rotatably connected between the front and rear inner walls of the storage slots 31. The front ends of the rotary posts 4 pass through the through holes on the surface of the explosion-proof control box body 1 and the clearance holes on the surface of the explosion-proof box door 2, and are equipped with knobs 12. Half-gears 5 are provided at both ends of the outer arc face of the rotary posts 4. The half-gears 5 are respectively installed to engage with the teeth on the surface of the adjacent baffles 36. The rotary posts 4 drive the half-gears 5 to rotate. When the half-gears 5 mesh with the teeth on the surface of the baffles 36, as the half-gears 5 rotate counterclockwise, they will... An upward force is applied to push the baffle 36 upward, providing space for the rotation of the connecting plate 32. Guide posts 6 are provided between the upper and lower inner walls of the slide 35. The guide posts 6 are vertically slidably connected to the guide holes on the surface of the baffle 36. Springs 7 are provided between the top wall of the slide 35 and the upper surface of the baffle 36. The springs 7 are movably sleeved on the outer arc surface of the guide posts 6. Under the guidance and support of the guide posts 6, and utilizing the elastic force of the springs 7, when the half-gear 5 is not in contact with the teeth on the surface of the baffle 36, the position of the baffle 36 is restricted by the elastic force of the springs 7. Threaded tubes 8 are rotatably connected to the outer arc surface of the rotating column 4. The threads at the front and rear ends of the threaded tubes 8 are in opposite directions. The two connecting plates 32 within the same receiving groove 31 are threadedly connected to one threaded tube 8. When the threaded tube 8 rotates, if the rotation of the connecting plate 32 in the same direction is unrestricted, it will cause the connecting plate 32 to rotate together. If the rotation of the connecting plate 32 in the same direction is restricted, it will cause the threaded tube 8 and the connecting plate 32 to rotate relative to each other. Through the threaded connection between the connecting plate 32 and the threaded tube 8, the two connecting plates 32 in the same receiving groove 31 move relative to each other due to the opposite direction of the threads at the front and rear ends of the threaded tube 8. The front and rear sides of the threaded tube 8 are provided with rings 9, and the front and rear ends of the outer arc of the rotating column 4 are provided with deflector rings 10. The deflector rings 10 are installed in conjunction with the rings 9. When the deflector plate of the deflector ring 10 contacts the convex plate of the ring 9, the threaded tube 8 will rotate together with the rotating column 4 as it rotates. When the deflector plate of the deflector ring 10 does not contact the convex plate of the ring 9, the rotating column 4 will rotate independently.The inner walls of the storage slots 31 are each equipped with positioning plates 11, which are installed in conjunction with the connecting plates 32. When the storage slots 31 of the two explosion-proof control boxes overlap laterally, the rotation angle of the connecting plates 32 is limited. Rubber pads 13 are provided on the outer surfaces of the baffles 36 to improve their sealing effect.

[0022] The working principle of the combined explosion-proof control box provided by this utility model is as follows: During use, the connecting plate 32 is located inside the storage slot 31. The teeth of the half-gear 5 do not contact the surface of the baffle 36. Under the elastic force of the spring 7, the position of the baffle 36 is restricted, thus sealing the opening of the storage slot 31 and preventing direct exposure of the combined components, improving the appearance of the explosion-proof control box. When the explosion-proof control box needs to be combined and connected with other explosion-proof control boxes, the corresponding knobs 12 are rotated. The knobs 12 drive the rotating column 4, half-gear 5, and dial ring 10 to rotate counterclockwise. At this time, the dial ring 10... The dial plate is not in contact with the convex plate of the ring 9. The threaded tube 8 and the rotating column 4 rotate relative to each other. When the half gear 5 meshes with the teeth on the surface of the baffle 36, the counterclockwise rotation of the half gear 5 will exert an upward force on the baffle 36, overcoming the elastic force of the spring 7 and pushing the baffle 36 upward to provide space for the rotation of the connecting plate 32. When the dial plate of the dial ring 10 contacts the convex plate of the ring 9, the rotation of the rotating column 4 will drive the threaded tube 8 to rotate counterclockwise. Because the counterclockwise rotation of the connecting plate 32 is unrestricted at this time, it will rotate with the threaded tube 8, causing the connecting plate 32 to protrude from the inside of the receiving groove 31. During operation, the connecting plate 32 applies force to the baffle 36, which has disengaged from the half gear 5, to prevent the baffle 36 from resetting. Simultaneously, the friction between the threaded tube 8 and the connecting plate 32 is greater than the spring force of the spring 7, preventing relative rotation between the threaded tube 8 and the connecting plate 32. Then, the connecting plate 32 is inserted into the storage slot 31 of another explosion-proof control box. By pushing the surfaces of the two explosion-proof control boxes to be flush, the lateral positions of the two explosion-proof control box storage slots 31 are aligned. Then, the connecting plate 32 continues to rotate via the rotating column 4. When the connecting plate 32 contacts the positioning plate 11 in the storage slot 31 of another explosion-proof control box, the connecting plate 32 is in a water-resistant state. In the flat state, the connecting plate 32 cannot continue to rotate counterclockwise. At this time, as the rotating column 4 continues to rotate counterclockwise, it will drive the threaded tube 8 to rotate relative to the connecting plate 32. Through the threaded connection between the connecting plate 32 and the threaded tube 8, the two connecting plates 32 in the same storage slot 31 move relative to each other due to the opposite direction of the threads at the front and rear ends of the threaded tube 8. This allows the insertion holes on the surface of the connecting plate 32 to be inserted into the insertion posts 34 in the storage slots 31 of other explosion-proof control boxes, thus combining the explosion-proof control boxes. When it is necessary to disassemble the explosion-proof control box, the rotating column 4 is rotated clockwise, causing the connecting plate 32 to repeat the above movement and retract into the storage slot 31.

[0023] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
