Description

Technical Field

[0001] This invention relates to the field of cabling technology, specifically to an inlet cabling device for preventing loosening in low-voltage intelligent engineering. Background Technology

[0002] Low-voltage intelligent engineering integrated cabling devices are often needed in office buildings, residences, hospitals and other places. Low-voltage intelligent systems are mainly for buildings, including high-rise buildings, residential areas, airports, docks, railways, highways and so on. The low-voltage box is a common component of low-voltage intelligent systems and is used to install equipment and manage cables.

[0003] However, during the use of the low-voltage box, the compact installation of multiple low-voltage devices inside results in a complex distribution of multiple wires. This not only makes it difficult to locate and find the wires during maintenance and disassembly, but also leads to wires becoming tangled. Furthermore, during normal operation inside the low-voltage box, there is a risk of accidental contact that could cause the wires to come loose, posing a safety hazard. Summary of the Invention

The rubber component is located inside the square groove on the side away from the rear wall of the cabinet, and the rubber component is fixedly connected to the support plate.

[0011] Preferably, the first mounting bracket is provided with a second mounting bracket inside. Both the first and second mounting brackets have multiple square slots on one side. The bottom of the second mounting bracket has a square slot. An electric push rod is provided inside the square slot. The two ends of the electric push rod are fixedly connected to the second mounting bracket and the first mounting bracket, respectively.

[0012] Preferably, the six mounting brackets correspond one-to-one with the six heat dissipation meshes. Multiple air extraction holes are provided on both sides of the interior of the square groove. The air extraction holes are opened on the support plate. Multiple limiting posts are fixedly connected to the side of the support plate near the rear wall of the cabinet.

[0013] Preferably, the heat dissipation structure includes two air guide grooves, one on the top of the support plate and another air guide groove, the top of which is provided with a second air guide groove. Semicircular plates are fixedly connected to both sides of the support plate. The second air guide groove is located at the top of the cabinet. A rubber component is provided on the outside of the second air guide groove. The rubber component is fixedly inserted into the top of the inner cavity of the cabinet.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. In this application, when the wire is subjected to a force towards the outside of the cabinet, the force exerted by the wire on the outer ring of the one-way bearing is the self-locking force of the inner and outer rings of the one-way bearing, and the force exerted by the wire on the outer ring of the two-way bearing is the self-locking force of the inner and outer rings of the two-way bearing. Therefore, the wire cannot move outward from the cabinet, which avoids the situation where the connection structure between the wire and the low-voltage equipment is subjected to force after the wire part on the outside of the cabinet is subjected to force, thereby reducing the loss caused by the wire falling off.

[0017] 2. In this application, when the wire is subjected to a force inward toward the cabinet, the force exerted by the wire on the outer ring of the first one-way bearing is the force in the direction of rotation of the inner and outer rings of the first one-way bearing, and the force exerted by the wire on the outer ring of the second one-way bearing is the force in the direction of rotation of the inner and outer rings of the second one-way bearing. Therefore, the wire can move into the cabinet, and the wire is clamped and limited by the rubber block. The rubber block applies a certain frictional force to the wire, preventing the wire from falling off due to vibrations caused by opening and closing the door. When operating multiple low-voltage devices inside the cabinet, since most of the wire is located on the rear side of the support plate, the wire is unlikely to affect the workers' work. Furthermore, after applying a certain force to the wire to move it into the cabinet, the wire overcomes the frictional force applied by the rubber block, and the length of the wire within the cabinet can be adjusted later, ensuring the flexibility of the wire arrangement.

[0018] 3. Under the action of the two support plates and multiple rubber parts in this application, the six heat dissipation meshes installed on the rear wall of the cabinet cavity have poor connectivity with the front side of the cabinet cavity. The mounting bracket 2 inside the mounting bracket 1 and multiple square slots 2 are opened on one side of the mounting bracket 1. The rear side of the low voltage equipment is connected to the space where the heat dissipation mesh is located through multiple square slots 2. The heat generated by the low voltage equipment is connected to the outside air through the heat dissipation mesh, which plays a role in heat dissipation. Dust can only move to the connection between the low voltage equipment and the wire after moving down, forward and down again, which reduces the possibility of dust moving to the connection between the low voltage equipment and the wire and depositing, and reduces the safety hazards caused by dust depositing on the low voltage equipment.

[0019] 4. In this application, the air pump can draw air from inside the support plate 1 through air guide pipe 1, air guide pipe 2, air guide circular groove 2 and air guide circular groove 1. The airflow enters the interior of square groove 1 through the weak voltage equipment set on one side. The suction force generated by the air pump is directly distributed to the surrounding area of ​​multiple weak voltage equipment by the weak voltage equipment installation structure, thereby improving the heat dissipation efficiency of the weak voltage equipment. The high-speed airflow output by the air pump acts on the six heat dissipation nets through air guide pipe 3, three air guide pipes 4 and three exhaust long grooves, cleaning the dust and impurities on one side of the heat dissipation nets and ensuring the efficiency of air circulation and heat exchange when the heat dissipation nets are put into use later.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example: Figures 1-13As shown, this invention provides a technical solution for an anti-loosening incoming wiring device for low-voltage intelligent engineering, including a low-voltage intelligent equipment cabinet 1. The low-voltage intelligent equipment cabinet 1 includes a cabinet body 11, six heat dissipation meshes 13 fixedly installed on the rear side of the cabinet body 11, and a door 12 hinged to the front side of the cabinet body 11. A low-voltage equipment installation structure 2 is installed inside the low-voltage intelligent equipment cabinet 1, and a heat dissipation structure 3 is installed between the low-voltage equipment installation structure 2 and the cabinet body 11. The low-voltage equipment installation structure 2 includes two support plates 21 rotatably connected inside the cabinet body 11, a support plate 213 fixedly installed inside the cabinet body 11, and a support plate 212 fixedly installed on the outside of the cabinet body 11. The bolt 226 is threaded to the cabinet 11; three square slots 25 are opened on one side of the support plate 21; a mounting bracket 26 is installed inside the square slot 25; a rubber part 27 is installed inside the square slot 25; a cable tray 23 is installed at the bottom of the square slot 25; and a rubber block 24 is installed on one side of the bottom of the cable tray 23. Multiple cable trays 229 are opened on one side of the support plate 213; multiple cable trays 214 are opened on one side of the support plate 212; and a one-way anti-loosening component is provided between the support plate 212 and the support plate 213. The one-way anti-loosening component includes a support plate 221 and a ring 227 that is rotatably sleeved on the outside of one of the bolts 226.

[0036] Specifically, two support plates 21 rotatably connected inside the cabinet 11 are used to support the installation of low voltage equipment. Four threaded holes 22 are provided on the outside of the square groove 25. The threaded holes 22 are opened on the side of the support plate 21 away from the rear wall of the cabinet 11. The threaded holes 22 meet the installation requirements of low voltage equipment through the threaded structure. The wiring groove 23 at the bottom of the square groove 25 is opened on one side of the support plate 21.

[0037] A support plate 213 is fixedly installed inside the cabinet 11. Multiple cable trays 229 are provided on one side of the support plate 213. A support plate 212 is fixedly installed on the outside of the cabinet 11. Multiple cable trays 214 are provided on one side of the support plate 212. The multiple cable trays 214 correspond one-to-one with the multiple cable trays 229. One cable tray 214 and its corresponding mounting bracket 219 form a wiring channel. One wire runs through one wiring channel, reducing the probability of wires being squeezed and tangled.

[0038] When installing low-voltage equipment using support plate 21, rotating support plate 21 adjusts its angle, allowing for easier operation and providing ample space for workers to maneuver wires. The low-voltage equipment is then fixed to support plate 21 using bolts that engage with the threaded structure and threaded holes 22 on the equipment. The equipment is positioned on one side of square slot 25. After passing the wire through the wiring channel, the wire is pulled from the back of support plate 21, passing one end through the adjacent wiring channel 23 at the bottom of square slot 25, and then pulled to the front of support plate 21 to install the wire and the low-voltage equipment. Wires are then inserted into cabinet 11 through different wiring channels, passing one end through wiring channel 23, thus completing the installation of one low-voltage device and its wiring. The three square slots 25 on support plate 21 are arranged from top to bottom, allowing for the installation of three low-voltage devices in a top-to-bottom order.

[0039] The low voltage equipment is installed on the two support plates 21 in the order of right to left. After the low voltage equipment on the right support plate 21 is installed, the right support plate 21 is pushed towards the rear wall of the inner cavity of the cabinet 11. During the rotation, a certain force is used to pull the part of the wire located on the outside of the cabinet 11 so that the wire is in a relatively taut state. Multiple limiting posts 211 are fixedly connected on the side of the support plate 21 near the rear wall of the cabinet 11. The rear end of the multiple limiting posts 211 is a semi-circular surface. When the limiting posts 211 contact the rear wall of the inner cavity of the cabinet 11, the movement of the support plate 21 is limited.

[0040] Since the rubber block 24 at the bottom of the cable tray 23 is fixedly connected to the side of the support plate 21 near the rear wall of the cabinet 11, the rubber block 24 is in contact with the cabinet 11. The deformation of the rubber block 24 squeezes and limits the wires, thus limiting the multiple wires installed on the three low-voltage devices on the support plate 21 and preventing the wires from becoming loose during the subsequent adjustment of the low-voltage devices. At the same time, the threaded groove 228 at the bottom of the support plate 21 moves and aligns with the bolt 226. The bolt 226 is rotated so that the top of the bolt 226 extends into the threaded groove 228. The bolt 226 is threadedly connected to the support plate 21, thus fixing the position of the support plate 21.

[0041] Then, following the steps described above, install the low-voltage equipment on the left support plate 21. After the limiting post 211 fixedly installed on the left support plate 21 contacts the rear wall of the inner cavity of the cabinet 11, rotate the bottom bolt 226 of the left support plate 21 to rotate and move it upward, thus completing the installation and fixing of the left support plate 21.

[0042] During the upward movement of the bolt 226 at the bottom of the left support plate 21, the ring 227 sleeved on the bolt 226 rotates and moves upward. The upward movement of the ring 227 pushes the support plate 223 fixedly connected to the bottom end of the support shaft 222 in the one-way anti-loosening assembly. The support plate 223 moves upward. Since the mounting groove 230 in the one-way anti-loosening assembly is formed on the rear side of the cabinet 11, the two support shafts 215 set at the top of the inner cavity of the mounting groove 230 are connected to the cabinet 11. The vertical position of the two support shafts 215 cannot change, and the vertical position of the multiple one-way bearings 216 fixedly sleeved on the outside of the support shafts 215 cannot change.

[0043] Two support shafts 217 are provided at the bottom of the inner cavity of the mounting groove 230. Multiple one-way bearings 218 are fixedly sleeved on the outside of the support shafts 217. The support shafts 217 are fixedly connected between two mounting brackets 219 provided inside the mounting groove 230. The bottom ends of two telescopic rods 220 fixedly inserted inside the mounting brackets 219 are fixedly connected to the cabinet 11. Under the support and limitation of multiple telescopic rods 220, the two mounting brackets 219 and the two support shafts 217 fixedly connected between the two mounting brackets 219 can only move up and down. The support plate 221 fixedly connected between the two support shafts 217 is fixedly installed at the top of the support shaft 222.

[0044] Therefore, after the ring 227 moves upward, the support plate 5 223 and the support shaft 3 222 move upward. The support shaft 3 222 then drives the support plate 4 221 to move upward. The support plate 4 221 then drives the two support shafts 217 to move upward. Since the wiring channel passes between the two upper support shafts 1 215 and the two lower support shafts 217, the multiple one-way bearings 1 216 on the outside of the support shaft 1 215 correspond one-to-one with the multiple wiring channels. The multiple one-way bearings 218 on the outside of the support shaft 217 also correspond one-to-one with the multiple wiring channels. Therefore, after the support shaft 217 moves upward, the one-way bearings 218 move upward. The one-way bearings 218 and 1 one-way bearings 216 clamp the wires inside the wiring channel.

[0045] When the wire is subjected to a force directed towards the outside of the cabinet 11, the force exerted by the wire on the outer ring of the one-way bearing 216 is a self-locking force between the inner and outer rings of the one-way bearing 216, and the force exerted by the wire on the outer ring of the one-way bearing 218 is a self-locking force between the inner and outer rings of the one-way bearing 218. Therefore, the wire cannot move outward from the cabinet 11, thus preventing the connection between the wire and the low-voltage equipment from being stressed due to the force on the wire portion outside the cabinet 11, and reducing the loss caused by the wire falling off.

[0046] When the wire is subjected to a force towards the inside of the cabinet 11, the force exerted by the wire on the outer ring of the one-way bearing 216 is the force in the direction of rotation of the inner and outer rings of the one-way bearing 216, and the force exerted by the wire on the outer ring of the one-way bearing 218 is the force in the direction of rotation of the inner and outer rings of the one-way bearing 218. Therefore, the wire can move into the cabinet 11, and the wire is clamped and limited by the rubber block 24. The rubber block 24 applies a certain frictional force to the wire, so the wire will not fall off due to the vibration generated by opening and closing the door 12. When operating multiple low-voltage devices inside the cabinet 11, since most of the wires are located behind the support plate 21, the wires are unlikely to affect the workers' construction. Furthermore, after a certain force is applied to the wire to move into the cabinet 11, the wire overcomes the frictional force applied by the rubber block 24, and the length of the wire in the cabinet 11 can be adjusted later to ensure the flexibility of the wire arrangement.

[0047] Mounting bracket 126 is located inside square groove 125 on the side near the rear wall of cabinet 11. Mounting bracket 126 is fixedly connected to support plate 121. Rubber component 27 is located inside square groove 125 on the side away from the rear wall of cabinet 11. Rubber component 27 is fixedly connected to support plate 21. Rubber component 27 is located on the side of the low voltage equipment near support plate 21. At this time, under the action of two support plates 21 and multiple rubber components 27, the six heat dissipation meshes 13 installed on the rear wall of the inner cavity of cabinet 11 have poor communication with the front side of the inner cavity of cabinet 11. The mounting bracket 28 inside the mounting bracket 26 and one side of the mounting bracket 26 are provided with multiple square slots 29. The rear side of the low voltage equipment is connected to the space where the heat dissipation net 13 is located through the multiple square slots 29. The heat generated by the low voltage equipment is connected to the outside air through the heat dissipation net 13, which plays a role in heat dissipation. Dust can only move to the connection between the low voltage equipment and the wire after moving down, forward and down again, which reduces the possibility of dust moving to the connection between the low voltage equipment and the wire and accumulating at the connection, thus reducing the safety hazards caused by dust accumulation on the low voltage equipment.

[0048] An electric push rod 210 is installed inside the square groove 29 opened at the bottom of one side of the mounting bracket 28. The two ends of the electric push rod 210 are fixedly connected to the mounting bracket 28 and the mounting bracket 26 respectively. When the low voltage equipment inside the low voltage equipment cabinet 1 is working at high power, the electric push rod 210 can be controlled to work. The electric push rod 210 drives the mounting bracket 28 to move down, so that the square groove 29 opened in the mounting bracket 28 is offset from the mounting bracket 28 opened in the mounting bracket 26, so that the square groove 25 can only be air-entered at the end closest to the low voltage equipment.

[0049] The heat dissipation structure 3 consists of two support plates 21 with air guide grooves 35 and air guide grooves 37. The support plates 21 are fixedly connected to both sides with semi-circular plates 34. The air guide grooves 37 are fixedly connected to the outside with rubber parts 36. The rubber parts 36 are fixedly inserted into the top of the inner cavity of the cabinet 11. The bottom of the rubber parts 36 contacts the support plates 21 and the two semi-circular plates 34. The rubber parts 36 seal the air guide grooves 37 and 35. The air guide grooves 37 are connected to the inside of the support plates 21 through the air guide grooves 35. The air guide pipes 33 are fixedly connected to the top of the two air guide grooves 37. The air guide pipes 32 are fixedly installed at the air inlet of the air pump 31.

[0050] The air pump 31 can draw air from the inside of the support plate 21 through the air guide pipe 32, the air guide pipe 33, the air guide groove 37, and the air guide groove 35. Multiple air extraction holes 231 are provided on both sides of the inside of the square groove 25. The air extraction holes 231 on the support plate 21 connect the inside of the square groove 25 with the inside of the support plate 21, so that a negative pressure area is formed inside the square groove 25. The elastic rubber part 27 deforms, allowing airflow to enter the inside of the square groove 25 through the weak voltage equipment set on one side of the square groove 25. The suction force generated by the air pump 31 is directly distributed by the weak voltage equipment installation structure 2 to the surrounding area of ​​multiple weak voltage equipment, improving the efficiency of heat dissipation for the weak voltage equipment.

[0051] Three air ducts 39 are fixedly connected to the air outlet of the air pump 31 via the air duct 38. The six heat dissipation meshes 13 are arranged in pairs. Each air duct 39 has a heat dissipation mesh 13 at its bottom. An exhaust slot 310 is opened on the side of the air duct 39 near the cabinet 11. Therefore, the high-speed airflow output by the air pump 31 acts on the six heat dissipation meshes 13 through the air duct 38, the three air ducts 39 and the three exhaust slots 310, cleaning the dust and impurities on one side of the heat dissipation meshes 13 and ensuring the efficiency of air circulation and heat exchange of the heat dissipation meshes 13.

[0052] Other, such as Figure 11 As shown, the top of the support plate 5 223 is provided with two guide vertical grooves 225. The guide vertical grooves 225 are opened on the cabinet 11. The bottom end of the support shaft 4 224 inserted inside the guide vertical groove 225 is fixedly connected to the adjacent support plate 5 223. The two support shafts 4 224 limit and guide the support plate 5 223, ensuring that the support plate 5 223 and the support shaft 3 222 can only move up and down.

[0053] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
