Description

Technical Field

[0001] This utility model relates to the field of PVC cable tray technology, specifically to ultra-weather-resistant and deformation-resistant PVC cable trays. Background Technology

[0002] PVC cable trays are mainly used for internal wiring of electrical equipment. They have the characteristics of insulation, arc prevention, flame retardancy and self-extinguishing. At the same time, they provide mechanical protection and electrical protection for the cables installed inside. They are widely used in home decoration, offices, industrial buildings and other fields to hide wires, organize wiring and improve the overall aesthetics.

[0003] For example, patent CN207398765U discloses a novel PVC cable tray, including a top cover and a corresponding tray body. It also includes fasteners, fastening positions, a first spring wire, a spring, and a second spring wire. Fasteners are located at the bottom of the top cover, and fastening positions corresponding to the fasteners are located at the bottom of the tray body. The spring is located inside the bottom of the tray body and below the fastening position. The upper part of the spring is a first spring wire, and the lower part is a second spring wire. The first spring wire is located inside the fastening position, and the second spring wire is located inside the bottom of the tray body and faces towards the center of the tray body, increasing the strength of the fastening positions on the tray body. A good fit ensures the cover and the trough fit tightly, improving the quality of the PVC cable tray. However, the deformation resistance and weather resistance of some PVC cable trays are not ideal. After long-term use, they are prone to deformation, fading, discoloration, surface cracking, cracking, aging, and brittleness, affecting their service life. This is especially true for cable trays laid outdoors, which are more susceptible to the effects of temperature and humidity changes, wind, sun, and rain. Moreover, deformation of the cable tray increases the difficulty of disassembly and reinstallation, and may even render it unusable.

[0004] To address the aforementioned issues, innovative designs are urgently needed based on the existing PVC cable trays. Utility Model Content

[0005] The purpose of this utility model is to provide an ultra-weather-resistant and deformation-resistant PVC cable tray to solve the problems mentioned in the background art, such as the current PVC cable trays having unsatisfactory deformation resistance and weather resistance, and being prone to deformation, fading, discoloration, surface cracking, cracking, aging, and brittleness after long-term use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an ultra-weather-resistant and deformation-resistant PVC cable trough, comprising a main trough body for protecting cables and a cover body that snaps onto the main trough body. The main trough body has slots on both sides, and the cover body has recessed slots on both sides below. The cover body is snapped onto the main trough body through the recessed slots and the slots. An external protrusion is provided on the inner side of the main trough body in the direction of contact with the recessed slot, and an internal protrusion is provided on the cover body to engage with the external protrusion. A reinforcement mechanism is provided in the main trough body to support and reinforce the shape of the cable trough.

[0008] Preferably, the rectangular frame has multiple inner grooves for packaging cables fixed inside, and adjacent inner grooves are fitted together.

[0009] Preferably, a support mechanism is provided between the inner tank and the cover to buffer external pressure and prevent deformation.

[0010] Preferably, the support mechanism includes a support spring sheet fixedly connected to the upper end of the inner groove, and a moving channel is provided between two adjacent support spring sheets; an arc-shaped seat is fixedly installed on the lower surface of the cover, and the arc-shaped seat is engaged above the support spring sheet.

[0011] Preferably, a support frame is fixedly connected to the lower end of the arc-shaped base, the support frame is slidably disposed in the moving channel, and an arc-shaped buffer plate is fixedly installed on the lower end face of the support frame; a buffer spring is fixedly connected to the inner side of the support spring, and the buffer spring is elastically supported under the arc-shaped buffer plate.

[0012] Preferably, a heat dissipation channel is provided between the inner tank and the rectangular frame, and multiple strip-shaped heat dissipation grooves are equally spaced on the bottom surface of the inner tank, with the strip-shaped heat dissipation grooves and the heat dissipation channel being connected in a continuous manner.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the ultra-weather-resistant and deformation-resistant PVC cable tray, through the slot, the inner groove, the outer protrusion and the inner protrusion, enable the cover to be stably installed on the main tray, which facilitates the control of the disassembly and assembly between the cover and the main tray.

[0014] Furthermore, the main channel is equipped with a reinforcement mechanism that can support and reinforce the shape of the cable trough. Rectangular frames and irregularly shaped reinforcement frames are installed inside the main channel. The irregularly shaped reinforcement frames are supported on both sides inside the main channel, which can increase the overall strength of the main channel and prevent the main channel from deforming under stress.

[0015] The rectangular frame contains multiple inner channels for storing cables, and the main channel has a through-flow heat dissipation channel and strip-shaped heat dissipation grooves to quickly dissipate the heat generated by the cables and prevent the cable tray from deforming due to excessive internal temperature.

[0016] Furthermore, a support mechanism is provided between the inner tank and the cover to buffer external pressure and prevent deformation. Support springs and arc-shaped seats are provided between the inner tank and the cover to strengthen the connection between the cover and the main tank and further improve the overall strength of the trough.

[0017] The surface of the cover is subjected to impact pressure, which is transmitted to the arc-shaped buffer plate through the arc-shaped seat and the upright. The arc-shaped buffer plate presses against the buffer spring, and the buffer spring and the support spring can buffer part of the pressure through elastic deformation, thereby maintaining the shape of the cover and the main groove and avoiding deformation of the groove from affecting subsequent disassembly operations.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: Please refer to Figures 1-7The present invention provides the following technical solution: an ultra-weather-resistant and deformation-resistant PVC cable trough, comprising a main trough 1 for protecting cables and a cover 2 that is snapped onto the main trough 1. The main trough 1 has slots 3 on both sides, and the cover 2 has recessed slots 4 on both sides below. The cover 2 is snapped onto the main trough 1 through the recessed slots 4 and the slots 3. An outer protrusion 41 is provided on the inner side of the main trough 1 in the direction of contact with the recessed slot 4, and an inner protrusion 42 is provided on the cover 2 to engage with the outer protrusion 41. A reinforcement mechanism is provided in the main trough 1 to support and reinforce the shape of the cable trough.

[0028] The reinforcement mechanism includes a rectangular frame 5 fixedly installed in the main tank 1, and an irregularly shaped reinforcement frame 6 fixedly connected between the rectangular frame 5 and the main tank 1. The side of the irregularly shaped reinforcement frame 6 closest to the main tank 1 is set as an arc structure.

[0029] The rectangular frame 5 contains multiple inner tanks 7 for packaging cables, and adjacent inner tanks 7 are fitted together. A heat dissipation channel 14 is provided between the inner tank 7 and the rectangular frame 5, and multiple strip-shaped heat dissipation grooves 15 are equally spaced on the bottom surface of the inner tank 7, which are connected to the heat dissipation channel 14.

[0030] The cover 2 is installed on top of the main groove 1 by the inner groove 4 and the slot 3. The inner protrusion 42 on the main groove 1 is engaged with the outer protrusion 41 on the cover 2, thus confining the cover 2 on the main groove 1. The main groove 1 is provided with a rectangular frame 5 and an irregularly shaped reinforcing frame 6. The side of the irregularly shaped reinforcing frame 6 closest to the inner wall of the main groove 1 has an arc-shaped structure. It is supported in the main groove 1 and provides lateral support and reinforcement for the main groove 1, thereby improving the overall strength of the main groove 1 and preventing deformation of its sides under pressure.

[0031] The rectangular frame 5 has multiple inner grooves 7 inside. During installation, the cables are installed in different inner grooves 7 to keep them separate and prevent heat transfer between them. At the same time, the heat generated by the cables can be quickly discharged to the outside through the strip heat dissipation grooves 15 and heat dissipation channels 14 to prevent heat from concentrating inside the cable tray and causing it to deform at high temperatures. Outdoor PVC cable trays can also be ventilated and dissipated through the strip heat dissipation grooves 15 and heat dissipation channels 14 to extend the overall service life of the PVC cable trays.

[0032] Example 2: Based on Example 1, a support mechanism is also disclosed, the specific structure of which is as follows: A support mechanism for buffering external pressure and preventing deformation is provided between the inner groove 7 and the cover 2. The support mechanism includes a support spring 8 fixedly connected to the upper end of the inner groove 7, and a moving channel 9 is provided between two adjacent support springs 8; an arc-shaped seat 10 is fixedly installed on the lower surface of the cover 2, and the arc-shaped seat 10 is engaged above the support spring 8.

[0033] A support frame 11 is fixedly connected to the lower end of the arc-shaped base 10. The support frame 11 is slidably disposed in the moving channel 9, and an arc-shaped buffer plate 12 is fixedly installed on the lower end face of the support frame 11. A buffer spring 13 is fixedly connected to the inner side of the support spring 8, and the buffer spring 13 is elastically supported below the arc-shaped buffer plate 12.

[0034] The inner groove 7 is supported by a support spring 8 and an arc-shaped seat 10 and is positioned below the cover 2. This increases the longitudinal strength of the main groove 1 and the cover 2, preventing deformation under longitudinal pressure. When the surface of the cover 2 is subjected to pressure, the pressure is transmitted to the arc-shaped seat 10, which presses down on the support spring 8 to buffer the pressure. At the same time, part of the pressure on the arc-shaped seat 10 is transmitted to the arc-shaped buffer plate 12 through the upright 11. The arc-shaped buffer plate 12 acts on the surface of the buffer spring 13, which further buffers the pressure through elastic deformation, preventing the cover 2 and the main groove 1 from being deformed under pressure, maintaining the integrity of the groove, and allowing the groove to be repeatedly disassembled and reused.
