Description

Technical Field

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

[0002] Distribution boxes are electrical equipment characterized by their small size, easy installation, special technical performance, fixed location, unique configuration functions, and lack of site restrictions. They are widely used, operate stably and reliably, have high space utilization, occupy little land, and have environmental benefits. During normal operation, circuits can be connected or disconnected by manual or automatic switches.

[0003] In the prior art, such as the explosion-proof distribution box proposed in patent application number "CN202122549187.9", this utility model causes the limiting block fixed to the limiting rod to slide downward by pressing down the limiting rod, thereby causing the connecting piece on the limiting block to slide downward. Since the locking rod is adapted to the limiting opening and is hinged to the connecting piece, the locking rod retracts into the limiting opening while the connecting piece slides downward, and the locking rod is released from the locking state. This makes it easy for the operator to slide out the limiting sleeve while pressing the limiting rod, thereby facilitating the disassembly of the heat sink for cleaning and replacement, and preventing dust from clogging the heat dissipation holes after long-term use.

[0004] However, in the aforementioned patent applications, the distribution box generally needs to be equipped with multiple electrical devices, and each electrical device needs to be connected by wires. Multiple wires are prone to getting tangled together, causing mess and making it difficult for staff to tidy them up. Utility Model Content

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] An explosion-proof distribution box, such as Figures 1-6 As shown, Figures 1-6 As shown, the device includes a housing 23, an explosion-proof junction box 21 fixedly installed on the bottom surface of the housing 23, a cover 1 fixedly installed on the front surface of the housing 23, an installation plate 14 fixedly installed on the inner wall of the housing 23, a safety railing 7, a phase sequence protector 10 and a power transformer 11 fixedly installed on the outer wall of the installation plate 14, an AC contactor 8 fixedly connected to the outer wall of the safety railing 7, a sealant layer 26 filling the space between the bottom surface of the housing 23 and the upper surface of the explosion-proof junction box 21, and a cable management mechanism fixedly installed on the inner wall of the explosion-proof junction box 21. The cable management mechanism includes a support plate 4, which is fixedly installed on the inner wall of the explosion-proof junction box 21, and several T-shaped sliders 9 are slidably connected to the outer wall of the support plate 4.

[0027] Among them, the safety barrier 7 can shield and protect the electrical equipment in the distribution box; the AC contactor 8 can connect or disconnect the main circuit in the distribution box; it is an electrical appliance that can use electromagnetic force to close or open the switch and has low-voltage release protection performance; the phase sequence protector 10 can protect the three-phase motor and other electrical equipment in the distribution box from damage or accidents caused by reversed power phase sequence; and the power transformer 11 can convert high voltage to low voltage or low voltage to high voltage to meet the voltage requirements of different equipment.

[0028] Two fixing holes 12 are provided on the outer wall of the bearing plate 4. A connecting block 13 is inserted into each fixing hole 12, and one end of each connecting block 13 is fixedly connected to the T-shaped slider 9. The front surface of the T-shaped slider 9 is rotatably connected to two clamping plates 15 via a shaft. A magnetic block 17 is fixedly installed on the inner wall of one clamping plate 15 at the end away from the T-shaped slider 9, and a magnetic block 20 is fixedly installed on the inner wall of the other clamping plate 15 at the end away from the T-shaped slider 9. The magnetic block 20 and the magnetic block 17 cooperate with each other and attract each other, so that one end of the two clamping plates 15 can be fixedly connected together, which helps to clamp and fix the wire placed between the two clamping plates 15.

[0029] Two slots 19 are provided on the outer wall of the connecting block 13. A U-shaped insert 18 is inserted into each slot 19. A return spring is installed between one end of the U-shaped insert 18 and the inner wall of the slot 19. A pull plate 16 is fixedly connected between the outer walls of the two U-shaped inserts 18. Several fixing holes 12 are provided on the outer wall of the bearing plate 4 near the edges of the two fixing holes 12. The fixing holes 12 fit with one end of the U-shaped insert 18. When one end of the U-shaped insert 18 is inserted into the corresponding fixing hole 12, the position of the connecting block 13 can be fixed, thereby fixing the position of the T-shaped slider 9.

[0030] When using the explosion-proof junction box 21, if it is necessary to install various electrical equipment inside, the two clamping plates 15 can be rotated with the connection point with the T-shaped slider 9 as the central axis to open the two clamping plates 15. Then, the wires connected to the electrical equipment can be placed between the two clamping plates 15. Then, the two clamping plates 15 can be rotated in the same way so that the magnetic block 17 and magnetic block 20 on the two clamping plates 15 attract each other, thereby fixing the position between the two clamping plates 15 and clamping and fixing the position of the wires. Similarly, multiple wires can be clamped and fixed in sequence through other sets of clamping plates 15, so that the wires are arranged and fixed on the outer wall of the bearing plate 4, making it difficult for them to get tangled and cause mess.

[0031] Pull the pull plate 16 away from the support plate 4, causing the two U-shaped inserts 18 to move along the slot 19 away from the T-shaped slider 9, so that one end of the U-shaped insert 18 moves out of the fixing hole 12. At this time, the return spring is stretched, which can release the fixation of the connecting block 13, thereby releasing the fixation of the T-shaped slider 9. At this time, the T-shaped slider 9 can be moved along the inside of the support plate 4 to adjust the spacing between each T-shaped slider 9. Thus, the position spacing of the multiple sets of clamps 15 installed on each T-shaped slider 9 can be adjusted according to the position of the wire to be fixed, effectively improving the applicability. After adjustment, release the pull plate 16. Under the action of the return spring, one end of the U-shaped insert 18 can be re-inserted into the corresponding fixing hole 12 to fix the position of the connecting block 13, thereby fixing the position of the T-shaped slider 9.

[0032] A fixing plate 25 is fixedly installed on the inner wall of the box cover 1. A display screen 5 is fixedly connected to the outer wall of the fixing plate 25. A glass pressure plate 2 is fixedly connected to the outer wall of the display screen 5. A transparent piece 6 is fixedly connected between the outer wall of the glass pressure plate 2 and the inner wall of the box cover 1. A button assembly 3 is fixedly installed on the outer wall of the box cover 1. An adhesive sealant layer 27 is filled between the button assembly 3 and the inner wall of the box cover 1.

[0033] Specifically, both the first sealant layer 26 and the second sealant layer 27 are epoxy resin sealants. The first sealant layer 26 can effectively fill the gap at the connection between the box 23 and the explosion-proof junction box 21. The second sealant layer 27 can effectively fill the gap between the inner wall of the button assembly 3 and the button assembly 3 and the glass pressure plate 2, preventing flammable gases or dust from entering the distribution box, thereby preventing safety accidents such as explosions or short circuits. After curing, the epoxy resin sealant forms a strong sealing layer that can suppress sparks and static electricity, reduce the risk of fire and explosion, and give the distribution box excellent explosion-proof performance.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
