Description
Technical Field
[0001] The present invention relates to the field of distribution cabinets, and particularly to a high-voltage distribution cabinet with convenient wiring. Background Art
[0002] With the development of industrial technology, modern distribution cabinet technology has become more and more perfect. In the past, when wiring a distribution cabinet, the distribution cabinet needed to be opened. Each time wiring was required, tools such as screwdrivers were used to open the wiring ports, and this operation would consume a lot of labor costs.
[0003] Secondly, when a distribution cabinet fails, it will catch fire. There are relatively expensive components inside the distribution cabinet, and once all are burned out, it will cause relatively large economic losses. Summary of the Invention
[0004] The purpose of the present invention is to provide a high-voltage distribution cabinet with convenient wiring. When the device is in use, the cable to be processed is inserted through the wire-passing hole and the locking short tube. The staff uses pliers to flatten the locking short tube until the locking teeth cut into the side wall of the cable. Then, the movable engaging frame is pulled open. When the bundling cylinder is inserted into the middle of the engaging frame, the engaging frame is released. The engaging frame retracts and merges together through the elastic force of the return spring to lock the engaging ring. Thus, the port of the cable can be inserted into the wiring hole to achieve wiring, so as to solve the problems raised in the above background art.
[0005] To achieve the above purpose, the present invention provides the following technical solution: A high-voltage distribution cabinet with convenient wiring, including a distribution box. A base is arranged at the bottom of the distribution box, and a cover plate is arranged in front of the distribution box. Two movably arranged movable wiring boards are arranged inside the distribution box. A slope surface is arranged on the outer side wall of the movable wiring board. An annular array of wiring holes is arranged on the side wall of the slope surface. A linear array of wiring heads is arranged on the inner side wall of the movable wiring board. Each wiring head is connected to a corresponding wiring hole one by one. A slope block is arranged on the outer side wall of the distribution box. The included angle formed by the outer end face and the vertical surface of the slope block is the same as the included angle formed by the slope surface and the vertical surface of the slope block. An engaging frame is arranged on the outer side wall of the slope block. A bundling cylinder is detachably installed inside the engaging frame.
[0006] Further, the engaging frame is divided into two halves. One half of the engaging frame is fixedly connected to the side wall of the slope block, and the other half of the engaging frame is movably connected to the slope block. An opening and closing mechanism is arranged between the two halves of the engaging frame. A engaging groove is arranged on the inner side wall of the engaging frame. An engaging ring matching the engaging groove is arranged on the outer side wall of the bundling cylinder. A wiring mechanism is also arranged on the bundling cylinder.
[0007] Further, the opening and closing mechanism includes tensioning blocks arranged on the upper and lower side walls of two half-latching frames. Two guide rods are arranged on the fixedly arranged tensioning blocks, and perforations matching the guide rods are arranged on the movably arranged tensioning blocks. A return spring is sleeved on the guide rods. The outer end of the return spring is fixedly connected to the side wall of the guide rod, and the inner end of the return spring is fixedly connected to the side wall of the movably arranged tensioning block.
[0008] Further, the wiring mechanism includes wire passing holes arranged in an annular array inside the bundling cylinder. Locking short tubes are arranged at the inner ports of the wire passing holes, and the positions of the locking short tubes correspond to those of the wiring holes one by one. A cable is inserted through each of the wire passing holes and the locking short tubes.
[0009] Further, locking teeth are arranged on the inner side walls of the locking short tubes.
[0010] Further, two shielding tiles are arranged below the distribution box. Insertion grooves matching the shielding tiles are arranged on the side wall of the distribution box. The outer side wall of the shielding tile is fixedly connected to the bottom surface of the distribution box through an energy storage spring, and the inner side wall of the shielding tile is fixedly connected to the bottom surface of the distribution box through hot-melt plastic. The energy storage spring is in a compressed state, and the shielding tile can abut against the slope surface in the vertical direction.
[0011] Further, two torsion springs are arranged at the bottom of the distribution box. A fireproof tile is arranged at the top end of each torsion spring. The edges of the two fireproof tiles are connected by a hot-melt strip. The planes of the two fireproof tiles are parallel to the plane of the cover plate.
[0012] In summary, due to the adoption of the above technology, the beneficial effects of the present invention are as follows:
[0013] First, when the device is in use, the cable to be processed is inserted through the wire passing holes and the locking short tubes. The worker uses pliers to flatten the locking short tubes until the locking teeth cut into the side wall of the cable, then pulls the movable latching frame apart. When the bundling cylinder is inserted into the middle of the latching frame, the latching frame is released. The latching frame retracts and merges together under the elastic force of the return spring to lock the latching ring. Furthermore, the end of the cable can be inserted into the wiring hole to achieve wiring.
[0014] Second, when the distribution box catches fire, the hot-melt plastic will melt. At this time, the potential energy of the energy storage spring will be released, and the shielding tile will rise up to squeeze the slope surface. The connection between the wiring hole and the cable end on the slope surface will be separated. After the hot-melt strip melts, the two fireproof tiles rotate 90 degrees through the torsion springs. Furthermore, the distribution box is separated into three compartments to isolate the combustion, so as to reduce the loss of the distribution box. Description of the Drawings

[0025] The present invention provides as Figures 1-7A high-voltage power distribution cabinet with convenient wiring is shown, including a distribution box 1. A base 2 is arranged at the bottom of the distribution box 1, and a cover plate 101 is arranged in front of the distribution box 1. Two movable wiring boards 5 are arranged inside the distribution box 1. A slope surface 501 is arranged on the outer side wall of the movable wiring board 5, and a ring of wiring holes 502 is arranged on the side wall of the slope surface 501. A linear array of connection heads is arranged on the inner side wall of the movable wiring board 5, and each connection head is connected to a wiring hole 502 in one-to-one correspondence. A slope block 8 is arranged on the outer side wall of the distribution box 1. The included angle formed by the outer end face and the vertical surface of the slope block 8 is the same as the included angle formed by the slope surface 501 and the vertical surface. A clamping frame 9 is arranged on the outer side wall of the slope block 8. A cable bundling tube 4 is detachably installed inside the clamping frame 9, and the cable bundling tube 4 and the clamping frame 9 can be separated. Thus, wiring operations can be carried out on the cable bundling tube 4 without frequently opening the distribution box 1. The inclined arrangement of the cable bundling tube 4, the clamping frame 9, and the slope block 8 can prevent rainwater from entering the distribution box 1 along the clamping frame 9.
[0026] The clamping frame 9 is divided into two halves. One half of the clamping frame 9 is fixedly connected to the side wall of the slope block 8, and the other half of the clamping frame 9 is movably connected to the slope block 8. An opening and closing mechanism is arranged between the two halves of the clamping frame 9. A clamping groove 901 is arranged on the inner side wall of the clamping frame 9, and a clamping ring 401 matching the clamping groove 901 is arranged on the outer side wall of the cable bundling tube 4. A wiring mechanism is also arranged on the cable bundling tube 4. When the movable clamping frame 9 is pulled open and the cable bundling tube 4 is inserted into the middle of the clamping frame 9, then the two halves of the clamping frame 9 are combined together. The cooperation between the clamping groove 901 and the clamping ring 401 can prevent the cable bundling tube 4 from slipping off.
[0027] The opening and closing mechanism includes tension blocks 902 arranged on the upper and lower side walls of the two halves of the clamping frame 9. Two guide rods 903 are arranged on the fixed tension blocks 902. A perforation matching the guide rods 903 is arranged on the movably arranged tension block 902. A return spring 904 is sleeved on the guide rod 903. The outer end of the return spring 904 is fixedly connected to the side wall of the guide rod 903, and the inner end of the return spring 904 is fixedly connected to the side wall of the movably arranged tension block 902. When the cable bundling tube 4 is inserted into the middle of the clamping frame 9, the clamping frame 9 is released. The clamping frame 9 retracts and combines together under the elastic force of the return spring 904 to lock the clamping ring 401.
[0028] The wiring mechanism includes a ring of wire passing holes arranged inside the cable bundling tube 4. Locking short tubes 402 are arranged at the inner ports of the wire passing holes. The positions of the locking short tubes 402 correspond to the wiring holes 502 one by one. A cable 3 is inserted through each of the wire passing holes and the locking short tubes 402, and the port of the cable 3 can be inserted into the wiring hole 502 to achieve wiring.
[0029] Locking teeth 403 are provided on the inner side walls of the locking short tubes 402. The operator uses pliers to flatten the locking short tubes 402 until the locking teeth 403 cut into the side wall of the cable 3.
[0030] Two shielding tiles 7 are provided below the distribution box 1. Insertion grooves matching the shielding tiles 7 are provided on the side wall of the distribution box 1. The outer side wall of the shielding tile 7 is fixedly connected to the bottom surface of the distribution box 1 through an energy storage spring 701. The inner side wall of the shielding tile 7 is fixedly connected to the bottom surface of the distribution box 1 through a thermoplastic 702. The energy storage spring 701 is in a compressed state. The shielding tile 7 can abut against the slope surface of the slope surface 501 in the vertical direction. When the distribution box catches fire, the thermoplastic 702 will melt. At this time, the potential energy of the energy storage spring 701 will be released, and the shielding tile 7 will rise up and squeeze the slope surface 501, and the connection between the wiring hole 502 on the slope surface 501 and the end of the cable 3 will be separated.
[0031] Two torsion springs 602 are provided at the bottom of the distribution box 1. Fireproof tiles 6 are provided at the tops of the torsion springs 602. The edges of the two fireproof tiles 6 are connected by a hot melt strip 601. The planes of the two fireproof tiles 6 are parallel to the plane of the cover plate 101. After the hot melt strip 601 melts, the two fireproof tiles 6 rotate 90 degrees through the torsion springs 602, and then the distribution box 1 is separated into three compartments to isolate the combustion, so as to reduce the loss of the distribution box 1.
[0032] Working principle: The beam tube 4 and the clamping frame 9 can be separated, so that wiring operations can be carried out on the beam tube 4 without frequently opening the distribution box 1. The beam tube 4, the clamping frame 9 and the slope block 8 are inclined to prevent rainwater from entering the interior of the distribution box 1 along the clamping frame 9. Pull the movable clamping frame 9 open. When inserting the beam tube 4 into the middle of the clamping frame 9, then merge the two half clamping frames 9 together. The cooperation between the clamping groove 901 and the clamping ring 401 can prevent the beam tube 4 from slipping off. When the beam tube 4 is inserted into the middle of the clamping frame 9, release the clamping frame 9. The clamping frame 9 retracts through the elastic force of the return spring 904 and merges together to lock the clamping ring 401. The port of the cable 3 can be inserted into the wiring hole 502 to achieve wiring. The operator uses pliers to flatten the locking short tubes 402 until the locking teeth 403 cut into the side wall of the cable 3. When the distribution box catches fire, the thermoplastic 702 will melt. At this time, the potential energy of the energy storage spring 701 will be released, and the shielding tile 7 will rise up and squeeze the slope surface 501, and the connection between the wiring hole 502 on the slope surface 501 and the end of the cable 3 will be separated. After the hot melt strip 601 melts, the two fireproof tiles 6 rotate 90 degrees through the torsion springs 602, and then the distribution box 1 is separated into three compartments to isolate the combustion, so as to reduce the loss of the distribution box 1.
