Lightweight composite cable tray

Abstract

This utility model relates to a lightweight composite cable tray, including a cable tray body. A set of auxiliary mechanisms are symmetrically arranged at the bottom of the cable tray body. The cable tray body includes a set of symmetrically arranged supports. A set of limiting arc plates are symmetrically fixed to the front and rear surfaces of the supports. A slot is opened on the inner side of the bottom of the supports. A baffle is engaged between the set of limiting arc plates. A slot plate is inserted into the slot. This utility model changes the design of the one-piece cable tray to a spliced ​​cable tray body, facilitating selective replacement of damaged areas without requiring overall replacement, thus reducing replacement costs.

Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and in particular to a lightweight composite cable tray. Background Technology

[0002] Cable trays are classified into various structures such as trough type, tray type, ladder type, and mesh type, and consist of supports, brackets, and installation accessories. Cable trays inside buildings can be installed independently or laid on various building (structure) supports and pipe rack supports. They should reflect the characteristics of simple structure, beautiful appearance, flexible configuration, and convenient maintenance.

[0003] Existing cable trays are often integrally molded structures. Therefore, when a section of the cable tray is damaged, it is difficult to replace the damaged area separately. The entire tray must be replaced, which increases the replacement cost. In view of this, we propose a lightweight composite cable tray. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a lightweight composite cable tray to solve the technical problem that the existing cable trays are often integrally molded structures, so when the cable tray is partially damaged, it is difficult to replace the damaged area separately, and the whole tray must be replaced, which increases the replacement cost.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a lightweight composite cable tray is designed, including a cable tray body, and a set of auxiliary mechanisms are symmetrically arranged at the bottom of the cable tray body;

[0006] The cable tray body includes a set of symmetrically arranged brackets. A set of limiting arc plates are symmetrically fixed on the front and back surfaces of the brackets. A slot is opened on the inner side of the bottom of the bracket. A baffle is locked between the set of limiting arc plates. A slot plate is inserted into the slot. A heat dissipation fin is provided at the middle of the bottom of the slot plate.

[0007] Preferably, the cable tray body is made of aluminum alloy as a frame and the surface is coated with graphene-modified epoxy resin.

[0008] Preferably, the baffle has concave arc-shaped sides, and the two sides of the baffle are matched and engaged with the top surface of a set of brackets.

[0009] Preferably, the slot plate forms a sliding engagement structure with the bracket via a slot, and the slot plate is fixedly connected to the heat dissipation fins.

[0010] Preferably, the auxiliary mechanism includes a cylindrical frame, a set of cylindrical frames being symmetrically fixed to the bottom of the support, a U-shaped locking rod penetrating through the inside of the set of cylindrical frames, a set of limiting ring plates being symmetrically fixedly sleeved on the surface of the U-shaped locking rod, and a spring being provided on one side of the limiting ring plate.

[0011] Preferably, when the spring is in its normal state, the end of the U-shaped lever is located inside the slot, and when the spring is in its critical compression state, the end of the U-shaped lever is just disengaged from the slot.

[0012] Preferably, the bottom inner side of the groove plate is provided with a groove that matches the end of the U-shaped clamp rod, and the U-shaped clamp rod is formed into an elastic structure by a limiting ring plate, a spring and a cylindrical frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model changes the design of the one-piece cable tray to a spliced ​​cable tray body, which facilitates selective replacement of damaged areas of the cable tray without the need for overall replacement, thus reducing replacement costs. Since the cable tray body is made of aluminum alloy with a graphene-modified epoxy resin coating, the cable tray body is both lightweight and high-performance, while its thermal conductivity is not significantly affected. The slots can guide the tray plates, improving assembly efficiency, and the wave-shaped heat dissipation fins effectively improve the heat dissipation of the device.

[0015] 2. This utility model allows the cable tray to be smoothly inserted into the slot by pulling down the U-shaped lever. After releasing the U-shaped lever, the end of the U-shaped lever pops out due to the spring rebound force and effectively engages in the inner slot at the bottom of the cable tray, quickly fixing the bracket to the cable tray. Subsequently, pulling down the U-shaped lever to release the restriction between the bracket and the cable tray allows the main body of the cable tray to be disassembled, which is quite convenient.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0024] A lightweight composite cable tray, see Figures 1 to 4 The cable tray body 1 includes an aluminum alloy frame with a graphene-modified epoxy resin coating on the surface. A set of auxiliary mechanisms 2 are symmetrically arranged at the bottom of the cable tray body 1.

[0025] The cable tray body 1 includes a set of symmetrically arranged supports 101. A set of limiting arc plates 102 are symmetrically fixed on the front and back surfaces of the supports 101. A slot 103 is opened on the inner side of the bottom of the supports 101. A baffle 104 is engaged between the set of limiting arc plates 102. Furthermore, the baffle 104 has concave arc shape on both sides. The two sides of the baffle 104 are matched and engaged with the top surface of the set of supports 101. A slot plate 105 is inserted into the slot 103. A heat dissipation fin 106 is provided at the middle of the bottom of the slot plate 105. Furthermore, the slot plate 105 and the supports 101 form an engaging and sliding structure through the slot 103. The slot plate 105 and the heat dissipation fin 106 are fixedly connected. This utility model changes the design of the one-piece cable tray to a spliced ​​cable tray body 1, which facilitates selective replacement of damaged areas of the cable tray without the need for overall replacement, thus reducing replacement costs. Since the cable tray body 1 uses aluminum alloy as the skeleton and is coated with graphene-modified epoxy resin, the cable tray body 1 combines lightweight and high performance, while its thermal conductivity is not significantly affected. The slot 103 can guide the slot plate 105, improving assembly efficiency, and the wave-shaped heat dissipation fins 106 effectively improve the heat dissipation of the device.

[0026] It is worth noting that the auxiliary mechanism 2 includes a cylindrical frame 201. A set of cylindrical frames 201 are symmetrically fixed to the bottom of the support 101. A U-shaped locking rod 202 runs through the inside of the set of cylindrical frames 201. A set of limiting ring plates 203 are symmetrically fixed on the surface of the U-shaped locking rod 202. A spring 204 is provided on one side of the limiting ring plate 203. When the spring 204 is in the normal state, the end of the U-shaped locking rod 202 is located inside the slot 103. When the spring 204 is in the compression critical state, the end of the U-shaped locking rod 202 just disengages from the slot 103. Furthermore, a slot matching the end of the U-shaped locking rod 202 is opened on the inner side of the bottom of the slot plate 105. The U-shaped locking rod 202 forms an elastic structure with the cylindrical frame 201 through the limiting ring plate 203, the spring 204 and the cylindrical frame 201. This invention allows the cable tray 105 to be smoothly inserted into the slot 103 by pulling down the U-shaped lever 202. After releasing the U-shaped lever 202, the end of the U-shaped lever 202 pops out and effectively engages in the inner groove at the bottom of the cable tray 105 due to the rebound force of the spring 204, thus quickly fixing the bracket 101 and the cable tray 105. Subsequently, pulling down the U-shaped lever 202 to release the restriction between the bracket 101 and the cable tray 105 allows for the disassembly of the cable tray body 1, which is quite convenient.

[0027] Working principle: Since the cable tray body 1 is made of aluminum alloy with a graphene-modified epoxy resin coating, it is both lightweight and high-performance, while its thermal conductivity is not significantly affected. The slot 103 guides the tray plate 105, and the wave-shaped heat dissipation fins 106 improve the heat dissipation of the device. By pulling down the U-shaped lever 202, the tray plate 105 is smoothly inserted into the slot 103. After releasing the U-shaped lever 202, the end of the U-shaped lever 202 pops out and engages in the inner groove at the bottom of the tray plate 105 due to the rebound force of the spring 204, quickly fixing the bracket 101 and the tray plate 105. Pulling down the U-shaped lever 202 again releases the restriction between the bracket 101 and the tray plate 105, allowing the cable tray body 1 to be disassembled. By changing the design of the one-piece cable tray to a spliced ​​cable tray body 1, it is convenient to selectively replace the damaged areas of the cable tray without replacing the whole structure, thus reducing replacement costs.
