Description

Technical Field

[0001] This utility model relates to the field of distribution box technology, and more specifically, to a reinforced explosion-proof distribution box. Background Technology

[0002] Explosion-proof distribution boxes are made of cast steel or welded steel plates and have high strength. Due to different usage environments, some explosion-proof boxes are sealed to prevent harmful gases from entering the box and causing an explosion. When assembling electronic components such as circuit breakers, they are fixed to the back plate with bolts.

[0003] A search revealed a reinforced explosion-proof distribution box in the prior art, with patent publication number CN219535340U. The specification states that the quick installation of multiple circuit breakers is achieved through the cooperation between the baffle, the square shell, and the first spring. This solves the problem that existing distribution boxes use rotating bolts to fix circuit breakers, which prolongs the operation time and reduces work efficiency in actual assembly due to the large number of circuit breakers to be installed.

[0004] However, in actual use, the casing is directly installed to the external mounting position through fasteners. As a result, when subjected to a force relative to the mounting position, the fasteners will deform due to the impact force, causing the fasteners to loosen from the mounting position, which will affect the installation stability of the distribution box. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a reinforced explosion-proof distribution box to solve the problem that the fasteners in the prior art will deform due to impact force, which will cause the fasteners to loosen from the installation position and thus affect the installation stability of the distribution box.

[0006] To solve the above technical problems, this utility model provides the following technical solution: a reinforced explosion-proof distribution box, including a box body, a plurality of support members fixedly connected to the rear side of the box body, a plurality of connecting rods slidably connected to the rear side inside the box body, a fixing member fixedly connected to the rear end of the connecting rods, two limiting grooves are opened on the upper and lower sides of the fixing member, a limiting block is engaged inside the limiting groove, and a rubber pad is fixedly connected to the rear end of the limiting block.

[0007] The connecting rod has two mounting slots inside. An elastic element is fixedly connected to the inner wall of the mounting slot. An mounting piece is fixedly connected to the other end of the elastic element. An mounting rod is fixedly connected to the end of the mounting piece away from the elastic element. The mounting rod passes through the fixing element and engages with the inside of the limiting block.

[0008] The box body has placement slots at its four internal corners, the connecting rod is fitted with an elastic element, and the end of the connecting rod away from the fixing element is fixedly connected to a push plate.

[0009] The rubber pad has multiple anti-slip grooves on its outer surface.

[0010] The mounting plate is slidably connected inside the mounting groove, and the mounting rod is slidably connected inside the mounting groove. The side of the mounting rod away from the mounting plate is an arc block structure.

[0011] The connecting rod is slidably connected inside the placement groove, and the push plate is slidably connected inside the placement groove.

[0012] One end of the second elastic element is fixedly connected to the inner wall of the placement groove, and the other end of the second elastic element is fixedly connected to the push plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In the above solution, the fixing component with connecting rod is slidably installed inside the housing, so that the housing can slide when impacted. A rubber pad is sleeved on the outside of the fixing component, which increases the friction between the fixing component and the installation position, making the fixing component less prone to deformation and less prone to displacement, thus making the installation stability of the distribution box higher.

[0022] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0023] Example 1: Please refer to Figures 1 to 5 This utility model provides a technical solution: a reinforced explosion-proof distribution box, wherein multiple support members 2 are fixedly connected to the rear side of the box body 1, the rear side of the support members 2 is in contact with the installation position, and is used to support the box body 1. Multiple connecting rods 3 are slidably connected to the rear side of the box body 1, so that the connecting rods 3 can move inside the box body 1. The rear end of the connecting rods 3 is fixedly connected to a fixing member 4, which is in contact with the external installation position. The fixing member 4 is installed on the external installation position by bolts. Two limiting grooves 5 are opened on the upper and lower sides of the fixing member 4. Limiting blocks 6 are engaged inside the limiting grooves 5. A rubber pad 7 is fixedly connected to the rear end of the limiting block 6. The limiting block 6 is used to limit the rubber pad 7, so that the rubber pad 7 can be installed on the limiting block 6. The rubber pad 7 is used to buffer the impact force received by the fixing member 4. Multiple anti-slip grooves 15 are opened on the outside of the rubber pad 7. The anti-slip grooves 15 are used to increase the contact friction between the rubber pad 7 and the installation position, so that the fixing member 4 is not easy to shift or deform.

[0024] When the enclosure 1 needs to be installed, the rubber pad 7 is attached to the fixing part 4, and the limiting block 6 is inserted into the limiting groove 5, so that the rubber pad 7 can be installed conveniently. Then, the rubber pad 7 is attached to the installation position, so that the support part 2 is attached to the installation position. Then, the fixing part 4 can be limited by bolts, so that the enclosure 1 can be installed conveniently. At this time, when the enclosure 1 is subjected to the relative impact force of the installation position, the enclosure 1 can slide backward, so that the support part 2 can deform, and the rubber pad 7 can deform, thus buffering the impact force. Under the action of the rubber pad 7, the fixing part 4 is not easy to deform or shift, thus making the installation stability of the distribution box high.

[0025] Example 2: Based on Example 1, in order to improve the installation stability of the rubber pad 7, two mounting grooves 8 are opened inside the connecting rod 3. An elastic element 11 is fixedly connected to the inner wall of the mounting groove 8, and a mounting piece 9 is fixedly connected to the other end of the elastic element 11. The mounting piece 9 is slidably connected inside the mounting groove 8. The mounting groove 8 limits the mounting piece 9, allowing the mounting piece 9 to slide smoothly. A mounting rod 10 is fixedly connected to the end of the mounting piece 9 away from the elastic element 11. The side of the mounting rod 10 away from the mounting piece 9 is an arc block structure, allowing the mounting piece 9 to slide inside the limiting block 6, thereby allowing the limiting block 6 to be easily disassembled. The mounting rod 10 is slidably connected inside the mounting groove 8, and the mounting groove 8 limits the mounting rod 10, preventing the mounting rod 10 from shifting when sliding. The mounting rod 10 passes through the fixing element 4 and engages with the inside of the limiting block 6, thereby limiting the fixing element 4 and the limiting block 6.

[0026] When it is necessary to install the fastener 4 and the rubber pad 7, by pushing the two mounting rods 10 to move to the same side, the mounting rods 10 can be deformed by the mounting plate 9 pressing the elastic element 11, thereby fitting the fastener 4 onto the connecting rod 3 and inserting the limiting block 6 into the limiting groove 5. Then, the mounting rods 10 are released, allowing the elastic element 11 to perform a reset movement, thereby allowing the elastic element 11 to push the mounting rod 10 through the fastener 4 and the limiting block 6 through the mounting plate 9 to engage, thus facilitating the installation of the limiting block 6 and the fastener 4.

[0027] Example 3: Based on Example 2, in order to improve the protection effect on the fixing member 4, placement grooves 12 are provided at the four corners of the box body 1. The connecting rod 3 is slidably connected inside the placement groove 12. The placement groove 12 provides movement space for the connecting rod 3. An elastic element 2 13 is sleeved on the outside of the connecting rod 3. A push plate 14 is fixedly connected to the end of the connecting rod 3 away from the fixing member 4. The push plate 14 is slidably connected inside the placement groove 12. The placement groove 12 limits the push plate 14, so that the push plate 14 can slide smoothly. One end of the elastic element 2 13 is fixedly connected to the inner wall of the placement groove 12, and the other end of the elastic element 2 13 is fixedly connected to the push plate 14.

[0028] When the housing 1 is subjected to an impact, the housing 1 will move backward, so that the housing 1 can pull the elastic element 2 13 through the placement groove 12 to deform, thereby allowing the placement groove 12 to perform a reset movement, so that the placement groove 12 can buffer the impact force.

[0029] The working process of this utility model is as follows:

[0030] When protection of the housing 1 is required, the rubber pad 7 is attached to the fixing member 4, and the limiting block 6 is inserted into the limiting groove 5, making it easy to install the rubber pad 7. Then, by pushing the two mounting rods 10 to move to the same side, the mounting rods 10 are deformed by the mounting plate 9 pressing the elastic element 11, thereby fixing the fixing member 4 onto the connecting rod 3. Then, the mounting rods 10 are released, allowing the elastic element 11 to return to its original position. The elastic element 11 then pushes the mounting rod 10 through the fixing member 4 and the limiting block 6 through the mounting plate 9, thus making it easy to install the limiting block 6 and the fixing member 4. Then, the rubber pad 7 and the fixing member 4 are attached to the limiting groove 5. The mounting positions are aligned, allowing the support 2 to fit snugly against the mounting position. Bolts can then be used to limit the fixing 4, facilitating the installation of the enclosure 1. When the enclosure 1 is subjected to an impact force relative to the mounting position, it slides backward, causing the elastic element 13 to deform through the placement groove 12. This causes the placement groove 12 to reset, thus buffering the impact force. Furthermore, the support 2 and rubber pad 7 deform, further buffering the impact force. Under the action of the rubber pad 7, the fixing 4 is less prone to deformation and displacement, resulting in high installation stability of the distribution box.
