Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable tray technology, and specifically to a modular cable tray device. Background Technology
[0002] Cable trays are rigid structural systems used to support, protect, and manage cables. They are widely used in construction, power, communications, industrial automation, and IT industries. Through their structural characteristics, cable trays attach, support, and fix cables to buildings or independently support cables passing through tunnels, caves, underground, and overhead locations. Like blood vessel walls, cable trays isolate cables from the outside environment, wrapping, supporting, and suspending them, effectively preventing direct exposure to the atmosphere and avoiding direct damage from factors such as sunlight, fog, rain, snow, and wind, thus extending the cable's service life. Cable trays can scientifically lay out various cables in energy and intelligent engineering projects, making rational use of building space and achieving the goals of reasonable structural design, simple and convenient construction, space saving, aesthetically pleasing layout, and ease of inspection, maintenance, and replacement.
[0003] Existing cable trays lack modularity in use. Non-modular cable trays require on-site cutting, welding, and drilling, demanding high levels of construction skills and experience. Especially in complex building structures or high-altitude operations, installation efficiency is low and safety hazards exist. Non-modular cable trays are integral structures that cannot be flexibly adjusted to meet actual needs. In space-constrained environments, this may restrict the installation of other equipment. Cable trays without modular design have high installation and maintenance complexity, low space utilization, and limited protective performance, resulting in safety hazards.
[0004] Therefore, it is necessary to invent a modular cable tray device to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to provide a modular cable tray device to solve the problem that the technology does not have the effect of modular use in practice.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular cable tray device, comprising a cable conduit, a lower housing, an upper housing, an inner gasket, an external mounting bracket, and corner protectors. The lower housing is disposed below the cable conduit, and the upper housing is disposed above the cable conduit. An inner gasket is disposed on the inner wall of the cable conduit. An external mounting bracket is disposed in the middle of both sides of the outer wall of the lower housing, and corner protectors are disposed on the lower edges of both sides of the outer wall of the lower housing. Preferably, the cable conduit is a split structure, with the middle part forming a hollow cylinder after assembly.
[0007] Preferably, a T-shaped plug is fixedly provided in the middle of the outer wall of the cable conduit, and a T-shaped slot matching the T-shaped plug is provided in the middle of the inner bottom surface of the lower housing and the middle of the inner top surface of the upper housing.
[0008] Preferably, limit strips are installed on both ends of the cable conduit, and limit grooves that engage and match the limit strips are provided on both sides of the inner wall of the lower housing.
[0009] Preferably, the lower housing has a mating groove at the middle of both ends, and the upper housing has mating plates fixedly installed on both sides of the bottom surface to engage with the mating groove.
[0010] Preferably, mounting holes are provided at both edges of the surface of the upper housing, and a plurality of mounting holes are provided.
[0011] Preferably, a mounting bolt is inserted into the middle of the mounting hole, the lower end of the mounting bolt is fixed to both sides of the top surface of the lower housing, and several mounting bolts are provided corresponding to the mounting hole. The upper end of the mounting bolt extends from the middle of the mounting hole to the top of the upper housing, and a fixing sleeve is installed on the upper end of the mounting bolt.
[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows: This modular cable tray device uses mechanical fastening to lock the upper and lower housings together, reducing the risk of loosening compared to traditional bolt connections. The length of the cable tray can be freely extended by adding cable conduit modules without redesigning the overall structure, adapting to future needs such as increased cable quantity or line adjustments. The modular design employs portable snap-fit and push-in installation methods in many places, which can effectively improve the efficiency of use and installation and enhance the flexibility of the device.

Detailed Implementation
[0015] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0016] This utility model provides, for example Figure 1-5 The modular cable tray device shown includes a cable conduit 1 and a lower housing 2. The cable conduit 1 is a split upper and lower structure. After assembly, the cable conduit 1 forms a hollow cylinder in the middle. A T-shaped plug 101 is fixedly installed in the middle of the outer wall of the cable conduit 1. T-shaped slots 102 that match the T-shaped plug 101 are opened in the middle of the inner bottom surface of the lower housing 2 and the middle of the inner top surface of the upper housing 3. Limiting strips 103 are installed on both sides of the ends of the cable conduit 1. Limiting grooves 104 that match the limiting strips 103 are opened on both sides of the inner wall of the lower housing 2. The lower housing 2 is located below the cable conduit 1. A docking groove 201 is opened in the middle of both ends of the lower housing 2. A docking plate 202 that matches the docking groove 201 is fixedly installed on both sides of the bottom surface of the upper housing 3. The cable conduit 1 adopts a split structure, which forms a hollow cylinder after assembly, making it easy for cables to be inserted. The inner wall is provided with an inner gasket 4, which plays a role in shock absorption and anti-friction, and protects the cable sheath. The T-shaped plug 101 on the outer wall of the cable conduit 1 is inserted and matched with the T-shaped slot 102 on the inner wall of the lower shell 2 and the upper shell 3 to achieve longitudinal positioning and prevent the cable conduit from sliding in the shell. The limiting strip 103 at the end of the cable conduit 1 engages with the limiting groove 104 on the inner wall of the lower shell 2 to further limit the lateral displacement of the cable conduit and ensure structural stability. The docking grooves 201 at both ends of the lower shell 2 engage with the docking plate 202 on the bottom surface of the upper shell 3 to form a closed cavity. A top housing 3 is provided above the cable conduit 1. Mounting holes 301 are provided on both sides of the surface of the top housing 3. Several mounting holes 301 are provided. A mounting bolt 302 is inserted into the middle of the mounting hole 301. The lower end of the mounting bolt 302 is fixed to both sides of the top surface of the lower housing 2. Several mounting bolts are provided corresponding to the mounting holes 301. The upper end of the mounting bolt 302 extends from the middle of the mounting hole 301 to the top of the top housing 3. A fixing sleeve 303 is installed on the upper end of the mounting bolt 302. An inner gasket 4 is provided on the inner wall of the cable conduit 1. An external mounting bracket 5 is provided on the middle of both sides of the outer wall of the lower housing 2. Corner guards 6 are provided on the lower edges of both sides of the outer wall of the lower housing 2. Multiple mounting holes 301 are opened on the surface of the upper housing 3. The mounting bolt 302 passes through the mounting hole 301 from the top surface of the lower housing 2 and is tightened by the fixing sleeve 303 at the upper end to lock the upper and lower housings together. The upper and lower housings are locked together by mechanical fastening, which reduces the risk of loosening compared with traditional bolt connection, and improves the overall modular use effect of the device. The working principle of this practical application is as follows: Refer to the instruction manual appendix Figure 1-5 For this type of modular cable tray device, the cable conduit 1 adopts an upper and lower split structure, which is combined to form a hollow cylinder to facilitate cable insertion. The inner wall is provided with an inner gasket 4 to reduce shock and prevent friction, and protect the cable sheath. The T-shaped plug 101 on the outer wall of the cable conduit 1 is inserted and matched with the T-shaped slot 102 on the inner wall of the lower shell 2 and the upper shell 3 to achieve longitudinal positioning and prevent the cable conduit 1 from sliding in the shell. The limiting strip 103 at the end of the cable conduit 1 is engaged with the limiting groove 104 on the inner wall of the lower shell 2 to further limit the lateral displacement of the cable conduit 1 and ensure structural stability. The docking grooves 201 at both ends of the lower shell 2 are engaged with the docking plate 202 on the bottom surface of the upper shell 3 to form a closed cavity. Multiple mounting holes 301 are opened on the surface of the upper shell 3. The mounting bolt 302 passes through the mounting hole 301 from the top surface of the lower shell 2 and is tightened by the fixing sleeve 303 at the upper end to lock the upper and lower shells. When using this device, first align the mating plate 202 of the upper housing 3 with the mating groove 201 of the lower housing 2, and slowly press down to make them engage. Then, insert the mounting bolt 302 into the mounting hole 301 of the upper housing 3, tighten the fixing sleeve 303, and fix the lower housing 2 to the building structure through the external mounting bracket 5. Insert the T-shaped plug 101 of the cable conduit 1 into the T-shaped slot 102 of the lower housing 2, and at the same time, make the limiting strip 103 engage with the limiting groove 104 to complete the positioning of the cable conduit 1. The cable conduit 1 adopts an upper and lower split design, which forms a hollow cylinder after assembly. It is not necessary to insert the cable from one end, and the upper housing 3 can be opened directly for cable laying. It is especially suitable for cable installation over long distances or in complex paths, effectively saving time. The upper and lower housings are locked by mechanical fastening, which reduces the risk of loosening compared to traditional bolt connections. The length of the cable tray can be freely extended by adding cable conduit 1 modules without redesigning the overall structure, adapting to future needs for increased cable quantity or line adjustment. The modular design adopts portable snap-fit and push-in installation methods in many places, which can effectively improve the efficiency of use and installation and increase the flexibility of the device.
