Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and in particular to a cable tray with efficient heat dissipation and ventilation. Background Technology

[0002] Cable trays are classified into trough type, tray type, ladder type, and mesh type structures, and consist of supports, brackets, and installation accessories. Cable trays inside buildings can be installed independently or laid on various building (structure) and pipe gallery supports. They should reflect the characteristics of simple structure, beautiful appearance, flexible configuration, and convenient maintenance. All parts need to be galvanized. After galvanizing, the cable trays installed on the exterior of the building are exposed. The low-voltage system of intelligent buildings usually consists of multiple information monitoring and communication facilities such as BA (Building Automation), OA (Office Automation), CA (Communication Automation), etc. Taking BA as an example, in addition to the necessary information monitoring of the building's own power supply, water supply and drainage, air conditioning, elevators and parking facilities, there are also several subsystems such as SA (Security Automation) and FA (Fire Automation) to achieve system integration or partial system integration. The grade and content of these systems are determined according to the functional requirements of the building. These systems include different types of cables and wires, some of which are active cables (power supply voltage is generally DC12 / 24 / 48V and AC220V). Since cables generate heat during operation, if the heat is not dissipated in time, it will cause cable damage. Traditional cable trays have fewer through holes, poor indoor ventilation, which affects heat dissipation. Furthermore, cable trays are not convenient for positioning cables of different diameters.

[0003] Therefore, those skilled in the art have provided a cable tray with efficient heat dissipation and ventilation to solve the problems mentioned in the background art. Utility Model Content

[0004] To address the issues of cable damage caused by heat generated during operation and the limited number of through holes in traditional cable trays, resulting in poor indoor ventilation and hindering heat dissipation, as well as the inconvenience of positioning cables of different diameters, this invention provides a cable tray with efficient heat dissipation and ventilation.

[0005] This utility model provides a cable tray with efficient heat dissipation and ventilation, using the following technical solution:

[0006] A cable tray with efficient heat dissipation and ventilation includes a cable tray body. Rectangular ventilation slots are provided at both the top and bottom ends of the cable tray body, and perforated ventilation slots are provided on both the left and right sides of the cable tray body. A positioning assembly is provided at the top of the cable tray body. The positioning assembly includes a positioning box.

[0007] By adopting the above technical solution, the ventilation of the cable tray body is ensured by setting rectangular ventilation slots and perforated ventilation slots. The small distance between the rectangular ventilation slots and perforated ventilation slots results in good ventilation. By setting a positioning component, pulling the pull head can drive the pressure plate to move upward. At this time, the positioning rod drives the positioning plate to compress the return spring, allowing the cable to pass through the cable tray body. Releasing the pull head causes the return spring to rebound, which can drive the pressure plate to limit the cable and prevent the cable from scattering. This can limit the cable of different diameters.

[0008] Optionally, the main body of the cable tray is an aluminum alloy frame, and the surface of the main body of the cable tray is coated with a corrosion-resistant coating.

[0009] By adopting the above technical solutions, the aluminum alloy frame ensures the strength of the cable tray body, and the corrosion-resistant coating increases the corrosion resistance of the cable tray body.

[0010] Optionally, the pressure plate is a thermally conductive metal plate, and the surface of the pressure plate is coated with a thermally conductive coating.

[0011] By adopting the above technical solutions, the heat-conducting metal plate and the heat-conducting coating facilitate heat conduction.

[0012] Optionally, the pull head is a metal pull head, and the surface of the pull head is provided with anti-slip texture.

[0013] By adopting the above technical solution, the metal zipper head ensures the strength of the zipper head, and the anti-slip texture plays a role in preventing slippage, making it convenient for users to pull the zipper head.

[0014] Optionally, the positioning box is fixedly connected to the cable tray body, and the positioning box has a cylindrical structure.

[0015] By adopting the above technical solution, the main body of the cable tray can support the positioning box.

[0016] Optionally, the top of the cable tray body is provided with a through hole, and the through hole fits with the positioning rod.

[0017] By adopting the above technical solution, the through hole facilitates the sliding of the positioning rod and can guide the positioning rod, increasing its stability.

[0018] Optionally, guide sliders are fixedly installed on both the left and right sides of the positioning plate, and a guide groove is opened in the inner cavity of the positioning box, with the guide sliders slidably connected to the guide groove.

[0019] By adopting the above technical solution, the guide slider and the guide groove are used together to guide the positioning plate and make the positioning plate move stably.

[0020] Optionally, mounting plates are fixedly installed around the perimeter of the cable tray body, and mounting holes are provided in the inner cavity of the mounting plates.

[0021] By adopting the above technical solution, bolts can be inserted into the mounting holes to fix the mounting plate, thereby allowing the device to be installed on the ceiling.

[0022] In summary, this utility model has the following beneficial effects:

[0023] 1. This utility model ensures the ventilation of the cable tray body by setting rectangular ventilation slots and perforated ventilation slots. The small distance between the rectangular ventilation slots and perforated ventilation slots results in good ventilation. By setting a positioning component, pulling the pull head can drive the pressure plate to move upward.

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0033] Example 1:

[0034] Please refer to Figure 1-3 A cable tray with efficient heat dissipation and ventilation includes a cable tray body 1. Rectangular ventilation slots 2 are provided at both the upper and lower ends of the cable tray body 1, and perforated ventilation slots 3 are provided on both the left and right sides of the cable tray body 1. The cable tray body 1 is an aluminum alloy frame, and the surface of the cable tray body 1 is coated with a corrosion-resistant coating. Mounting plates 4 are fixedly installed around the cable tray body 1, and mounting holes are provided in the inner cavity of the mounting plates 4.

[0035] In this embodiment: By setting rectangular ventilation slots 2 and perforated ventilation slots 3, the ventilation of the cable tray body 1 is ensured. The rectangular ventilation slots 2 and perforated ventilation slots 3 are close together, resulting in good ventilation. The aluminum alloy frame ensures the strength of the cable tray body 1, and the corrosion-resistant coating increases the corrosion resistance of the cable tray body 1. Bolts are inserted into the mounting holes to fix the mounting plate 4, thereby allowing the device to be installed on the ceiling.

[0036] Example 2:

[0037] Reference Figure 1-5 The top of the cable tray body 1 is provided with a positioning component 5, which includes a positioning box 501. A return spring 502 is fixedly installed on the top of the inner cavity of the positioning box 501, a positioning plate 503 is fixedly installed on the bottom of the return spring 502, a positioning rod 504 is fixedly installed on the inner cavity of the positioning plate 503, a pressure plate 506 is fixedly installed on the bottom of the positioning rod 504, and a pull head 505 is fixedly installed on the top of the positioning rod 504. The pressure plate 506 is a heat-conducting metal plate. The surface is coated with a thermally conductive coating. The pull head 505 is a metal pull head, and the surface of the pull head 505 is provided with anti-slip texture. The positioning box 501 is fixedly connected to the cable tray body 1. The positioning box 501 is a cylindrical structure. The top of the cable tray body 1 is provided with a through hole, and the through hole fits with the positioning rod 504. Guide sliders 507 are fixedly installed on both the left and right sides of the positioning plate 503. The inner cavity of the positioning box 501 is provided with a guide groove 508, and the guide slider 507 is slidably connected to the guide groove 508.

[0038] In this embodiment: by setting a positioning component 5, pulling the pull head 505 can drive the pressure plate 506 to move upward. At this time, the positioning rod 504 drives the positioning plate 503 to compress the return spring 502, passing the cable through the cable tray body 1. Releasing the pull head 505, the return spring 502 rebounds and drives the pressure plate 506 to limit the cable, preventing the cable from scattering. It can limit cables of different diameters. The heat-conducting metal plate and heat-conducting coating facilitate heat conduction. The metal pull head ensures the strength of the pull head 505, and the anti-slip texture plays an anti-slip role, making it convenient for users to pull the pull head 505. The cable tray body 1 can support the positioning box 501. The through hole facilitates the sliding of the positioning rod 504 and can guide the positioning rod 504 to increase stability. The guide slider 507 and the guide groove 508 work together to guide the positioning plate 503, making the positioning plate 503 stable when moving.

[0039] The implementation principle of this utility model is as follows: In use, bolts are inserted into the mounting holes to fix the mounting plate 4, thereby allowing the device to be installed on the ceiling. Pulling the pull head 505 moves the positioning rod 504, which in turn moves the pressure plate 506. At this time, the positioning rod 504 causes the positioning plate 503 to compress the return spring 502, allowing the cable to pass through the cable tray body 1, so that the cable is located between the pressure plate 506 and the cable tray body 1. Releasing the pull head 505 causes the return spring 502 to rebound, which in turn causes the positioning plate 503 to rebound. The positioning plate 503 then causes the positioning rod 504 and the pressure plate 506 to rebound, thus clamping the cable.

[0040] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
