Description

Technical Field

[0001] The utility model relates to the technical field of weak current cable trays, in particular to the cable tray structure for weak current engineering. Background Technique

[0002] Weak current engineering is a classification of power applications. Power applications can be divided into strong current and weak current according to the strength of power transmission. The electricity used in buildings and building complexes generally refers to weak current below 220V 50Hz AC. It mainly provides people with electric energy and converts electric energy into other forms of energy, such as air-conditioning power, lighting power, motive power, etc. In weak current engineering, cable trays are usually used to support and fix pipelines.

[0003] After retrieval, a cable tray structure for weak current engineering (authorized announcement number: CN 219833649U) "comprises a cable tray body, on which a heat dissipation component, an inverted U-shaped upper cable tray and a U-shaped lower cable tray are provided. A plurality of reinforcement components are arranged in the U-shaped lower cable tray. By setting the reinforcement components, the adjusting bolt, the arc-shaped bracket and the pressing plate cooperate with each other, and the cable can be firmly fixed between the U-shaped upper cable tray and the U-shaped lower cable tray. This structure can prevent the cable from being displaced when being pulled, so that the cables exposed at both ends of the cable tray body are longer, improving safety; by setting the heat dissipation component, the heat generated by the cable during use can be discharged from the mesh plate, heat dissipation hole 1 and heat dissipation hole 2. And when the cable tray installed outdoors encounters rainy days, the accumulated water can be discharged from the mesh plate. This structure improves the heat dissipation effect while avoiding rainwater accumulation in the cable tray and prolongs the service life of the cable".

[0022] Refer to Figure 1 - Figure 4, the bridge structure of the weak current project, including the storage bridge 1, there is a top cover 2 inside the storage bridge 1, and a fixing mechanism 3 is provided at the bottom of the top cover 2. The fixing mechanism 3 includes elastic grooves 301 symmetrically opened at the top of the top cover 2. Inside both elastic grooves 301, there is a sliding rod 302 fixedly connected. On the outer sides of both sliding rods 302, there is a slider 303 slidably connected. On the outer sides of both sliding rods 302, there is a spring 304 sleeved. At the bottom of both sliding rods 302, there is a downward pressing rod 307 rotatably connected. At the bottom of the top cover 2, there are inclined struts 305 symmetrically rotatably connected. At the top of both inclined struts 305, there is a rotating block 306 fixedly connected. The two rotating blocks 306 are respectively rotatably connected to the other ends of the two downward pressing rods 307. Inside the storage bridge 1, there are connection covers 308 symmetrically provided. At the bottom of both connection covers 308, there is a pressing roller 309 rotatably connected. At the top of both connection covers 308, there is a connection block 310 fixedly connected. The two inclined struts 305 are respectively rotatably connected to the two connection blocks 310. At the bottom of the storage bridge 1, there are mounting brackets 5 symmetrically installed. Both mounting brackets 5 are designed in a concave shape, and the two mounting brackets 5 and external mounting components are installed by bolts.

[0023] In the above technical solution, considering that there is a problem of adjusting the height of the pressing plate by rotating the adjusting bolt, but when the L-shaped mounting plate is fixed to the wall, the space reserved for operating the adjusting bolt becomes very narrow, which is not conducive to rotating the adjusting bolt, and there are still certain deficiencies in actual use. To solve such problems, the specific operations are as follows:

[0024] Refer to Figure 1 - Figure 4 , in a preferred embodiment, pass the line through the storage bridge 1, then push the top cover 2 and cover the top cover 2 inside the storage bridge 1. During the process of pushing the top cover 2, the pressing roller 309 rotates on the top of the line, and the spring 304 pushes the slider 303 to slide on the outer side of the sliding rod 302. Then the downward pressing rod 307 presses the inclined strut 305 downward, and the inclined strut 305 rotates at the bottom of the top cover 2, thereby driving the pressing roller 309 to press the line tightly inside the storage bridge 1. Through the set fixing mechanism 3, the fixing of the line is realized, avoiding the displacement of the line under pulling, ensuring the use safety of the line, with a simple structure and high practicality.

Rubber pads for buffering are fixedly connected to the outer walls of both pressing rollers 309. One end of the storage bridge 1 is symmetrically and fixedly connected with a blocking plate 8, and the blocking plate 8 is used in cooperation with the top cover 2. By arranging the classification grooves 4, the wires can be classified and pressed, which is convenient for maintenance. By arranging the heat dissipation grooves 6 and the dust-proof net 7, the wires can be dissipated heat, avoiding damage caused by excessive wire temperature. By arranging the blocking plate 8, the top cover 2 can be prevented from slipping.

[0026] Working principle: In actual use, the staff first passes the wire through the storage bridge 1, and then pushes the top cover 2 to cover the top cover 2 inside the storage bridge 1. During the process of pushing the top cover 2, the pressing roller 309 rotates on the top of the wire, the spring 304 pushes the slider 303 to slide on the outer side of the slide bar 302, and then the lower pressing rod 307 presses the inclined strut 305 downward. The inclined strut 305 rotates at the bottom of the top cover 2, and then drives the pressing roller 309 to press the wire tightly inside the storage bridge 1. Then, the mounting bracket 5 is installed with external mounting components. Thus, the staff has completed the installation work of the weak current engineering wires.
