Description

Technical Field

[0001] The utility model relates to the technical field of control boxes, in particular to an explosion-proof control box. Background Art

[0002] Explosion-proof control boxes are electrical equipment used in hazardous environments. They primarily control and protect electrical systems, ensuring safe operation in explosive environments. They play a crucial role in industrial production, particularly in the petrochemical, coal mining, and power industries. An explosion-proof control box typically consists of a metal enclosure, internal control devices, and electrical connections. The enclosure is designed with explosion-proof materials and structures to withstand potential internal explosion pressures and prevent sparks or high temperatures from being transmitted from the inside of the enclosure to the outside, thereby preventing external explosions. They are suitable for environments with gases, steam, and mist. The enclosure is reinforced to withstand internal explosions and prevent them from spreading externally. For gas environments, safety enhancements are implemented on electrical equipment to reduce sparks or high temperatures, preventing explosions. For locations with stringent environmental requirements, the energy consumption of electrical equipment is reduced, preventing explosions during normal operation. A thick, sturdy enclosure isolates the internal and external environments, preventing internal explosions from spreading externally. Improvements to the equipment's electrical components reduce sparks and heat sources, thereby enhancing safety. Energy released during equipment failures is limited to prevent explosions.

[0003] At present, in order to meet the explosion-proof standards, the structure of the explosion-proof control box is usually relatively solid, and the volume and weight may be larger than the ordinary control box, which is very laborious to move. This will cause operators to spend too much time and energy on the equipment, thereby reducing the overall work efficiency; therefore, it does not meet the existing needs. For this, we propose an explosion-proof control box. Utility Model Content

[0004] The utility model provides an explosion-proof control box, which has the beneficial effect of ensuring the stability of the control box during use, preventing the equipment from being displaced due to vibration or external force, thereby improving the stability and safety of the equipment. It solves the problem mentioned in the above background technology that in order to meet the explosion-proof standards, the structure of the explosion-proof control box is usually relatively solid, and the volume and weight may be larger than that of an ordinary control box, making it very difficult to move, which will cause the operator to spend too much time and energy on the equipment, thereby reducing the overall work efficiency.

[0005] The utility model provides the following technical solutions: an explosion-proof control box, comprising a control box body and a mobile box, wherein the control box body is installed inside the mobile box, a sliding wheel is installed at the bottom of the mobile box, a mounting groove is opened on the side of the mobile box, a stabilizing column is connected to the inside of the mounting groove, and the stabilizing column is used in conjunction with the mounting groove.

[0006] As an optional solution for an explosion-proof control box described in the utility model, there are a plurality of sliding wheels, and the plurality of sliding wheels are connected to the bottom of the mobile box.

[0007] As an optional solution for an explosion-proof control box described in the utility model, wherein: a fixing block is connected to the inside of the installation groove, a first notch is opened on the side of the fixing block, and a second notch is opened on the inner wall of the installation groove.

[0008] As an optional solution for an explosion-proof control box described in the utility model, the outer side of the stabilizing column is connected to a slide cylinder, the slide cylinder slides with the inner wall of the installation groove, and the end of the stabilizing column is connected to a push disk.

[0009] As an optional solution for an explosion-proof control box described in the utility model, the bottom of the stabilizing column is connected to a fixing column, the outer side of the fixing column is connected to a first folding plate, and the end of the first folding plate is provided with a second folding plate.

[0010] As an optional solution for an explosion-proof control box described in the present invention, a rotation pin is inserted into the end of the second folding plate, a torsion spring is sleeved on the outside of the rotation pin, and the other end of the torsion spring is connected to the end of the first folding plate.

[0011] As an optional solution for an explosion-proof control box described in the present invention, the other end of the second folding plate is connected to a fixing block, and a return spring is sleeved on the outer side of the fixing block.

[0012] As an optional solution for an explosion-proof control box described in the utility model, wherein: a fixed plate is provided at the other end of the fixed block, the fixed plate is provided at the bottom of the mobile box, a gravity block is inserted into the bottom of the fixed plate, the fixed block is inserted into the middle of the fixed plate, and the fixed block is connected to the side of the gravity block.

[0013] The utility model has the following beneficial effects:

[0014] 1. This explosion-proof control box, through the provision of a stabilizing column, allows the control box body to be moved to a fixed position and the push disk to be rotated, causing the push disk to drive the slide cylinder to slide within the mounting slot. The stabilizing column drives the first and second folding plates, causing the side of the first folding plate to unlock from the first notch, the side of the first folding plate to engage within the second notch, and the second folding plate to press the fixing column and the gravity block at the end of the fixing column to the ground. The stabilizing column and folding plate design effectively secures the explosion-proof control box in a predetermined position. By unlocking the side of the first folding plate from the first notch and engaging it within the second notch, the stability of the control box during use is ensured, preventing the equipment from shifting due to vibration or external forces, thereby improving the stability and safety of the equipment. This solves the problem that explosion-proof control boxes are generally more robust in structure to meet explosion-proof standards, and may be larger and heavier than ordinary control boxes, making them very laborious to move. This causes operators to spend excessive time and energy on moving the equipment, thereby reducing overall work efficiency.

[0015] 2. This explosion-proof control box features a first folding plate that cooperates with a second folding plate. When the push disk is turned, the torsion spring drives the rotating pin to bend the first and second folding plates, locking them into the second notch. The return spring abuts the second folding plate, preventing the side of the first folding plate from loosening and causing the sliding wheel to slip. The return spring maintains close contact between the side of the first folding plate and the second notch, effectively preventing loosening between the folding plates. This design avoids the problem of the sliding wheel slipping due to looseness between the first folding plate and the second notch, ensuring that the device will not shift due to loose fixation during use.

[0022] Example 1: This example aims to solve the problem that in order to meet explosion-proof standards, the structure of the explosion-proof control box is usually relatively strong, and the volume and weight may be larger than that of ordinary control boxes, which is very laborious to move. This will cause operators to spend too much time and energy on the equipment, thereby reducing overall work efficiency. Figure 1-4 A explosion-proof control box includes a control box body 110 and a mobile box 120. The control box body 110 is installed inside the mobile box 120. A sliding wheel 121 is installed at the bottom of the mobile box 120. A mounting groove 130 is opened on the side of the mobile box 120. A stabilizing column 140 is connected to the inside of the mounting groove 130. The stabilizing column 140 is used in conjunction with the mounting groove 130.

[0023] A plurality of sliding wheels 121 are provided, and the plurality of sliding wheels 121 are connected to the bottom of the moving box 120 .

[0024] A fixing block 131 is connected to the interior of the installation slot 130 . A first notch 132 is defined on a side of the fixing block 131 . A second notch 133 is defined on an inner wall of the installation slot 130 .

[0025] A slide 141 is connected to the outer side of the stabilizing column 140 . The slide 141 is slidably engaged with the inner wall of the installation groove 130 . A pressing plate 142 is connected to the end of the stabilizing column 140 .

[0026] The bottom of the stabilizing column 140 is connected to a fixing column 143 , the outer side of the fixing column 143 is connected to a first folding plate 144 , and the end of the first folding plate 144 is provided with a second folding plate 145 .

[0027] A rotation pin 150 is inserted into the end of the second folding plate 145 , and a torsion spring 151 is sleeved on the outer side of the rotation pin 150 . The other end of the torsion spring 151 is connected to the end of the first folding plate 144 .

[0028] The other end of the second folding plate 145 is connected to a sliding post 152 , and a return spring 153 is sleeved on the outer side of the sliding post 152 .

[0029] A fixed plate 154 is provided at the other end of the sliding column 152, and the fixed plate 154 is provided at the bottom of the moving box 120. A gravity block 155 is inserted into the bottom of the fixed plate 154. The sliding column 152 is inserted into the middle of the fixed plate 154, and the sliding column 152 is connected to the side of the gravity block 155.

[0030] In this embodiment: through the setting of the stabilizing column 140, when the control box body 110 is moved to a fixed position, the push disk 142 is rotated, and the push disk 142 drives the slide 141 to slide inside the installation groove 130, and the stabilizing column 140 drives the first folding plate 144 and the second folding plate 145, so that the side of the first folding plate 144 is unlocked from the first slot 132, and the side of the first folding plate 144 is engaged with the inside of the second slot 133, and the second folding plate 145 presses the sliding column 152 and the gravity block 155 at the end of the sliding column 152 to be placed on the ground. The stabilizing column 140 and the folding plate design can effectively fix the explosion-proof control box firmly in the predetermined position. By unlocking the side of the first folding plate 144 from the first slot 132 and engaging it inside the second slot 133, the stability of the control box during use is ensured, and the equipment is prevented from shifting due to vibration or external force, thereby improving the stability and safety of the equipment. This solves the problem that in order to meet explosion-proof standards, the structure of the explosion-proof control box is usually more solid, and the volume and weight may be larger than that of an ordinary control box, making it very difficult to move. This will cause operators to spend too much time and energy on the equipment, thereby reducing overall work efficiency.

[0032] In this embodiment, the first folding plate 144 is provided, and the first folding plate 144 cooperates with the second folding plate 145. When the push disk 142 is rotated, the torsion spring 151 drives the rotation pin 150, causing the first folding plate 144 and the second folding plate 145 to bend and engage within the second notch 133. The return spring 153 abuts the second folding plate 145, preventing the side of the first folding plate 144 from loosening and causing the sliding wheel 121 to slide. The function of the return spring 153 is to maintain the side of the first folding plate 144 in close contact with the second notch 133, thereby effectively preventing looseness between the folding plates. This design avoids the problem of sliding the sliding wheel 121 due to looseness between the first folding plate 144 and the second notch 133, ensuring that the device will not move due to loose fixation during use.
