Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, and more particularly to a self-locking reinforced cable tray. Background Technology

[0002] Cable trays are supporting structures used for laying cable lines and are frequently used equipment in electrical engineering installations. Cable trays are generally divided into two types: trays and ladder trays. Among them, perforated trays have become the mainstream choice for cable laying in industrial and civil buildings due to their core advantages of efficient heat dissipation, economic flexibility, and convenient maintenance. However, existing tray-type cable trays have the following shortcomings:

[0003] 1. Insufficient structural strength: When the span of the cable tray is large (especially in scenarios where the span exceeds 4 meters), the cable is prone to bending deformation or even breakage when it is under heavy load or subjected to external impact, which affects the quality of cable laying. The sagging problem in the middle of the cable tray is particularly prominent and seriously affects cable safety.

[0004] 2. The cover plate is inconvenient to disassemble. Existing cable trays usually use a large number of screws or bolts to fix the cover plate when installing it, which makes installation and disassembly troublesome and causes inconvenience for maintenance. Moreover, the bolts are prone to rust after long-term use, and there is a risk of breakage and loosening. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a self-locking reinforced cable tray to solve the technical problems of insufficient structural strength and inconvenient disassembly of the cover plate in the prior art.

[0006] This utility model is achieved by the following technical solution: a self-locking reinforced cable tray, comprising a tray body and a cover plate;

[0007] The cable tray body includes a base plate and a side plate. The side plate is connected to the side wall of the base plate. The base plate has a first reinforcing part on both sides, which is located close to the side plate. The top of the side plate has a connecting second reinforcing part and a first snap-fit ​​part.

[0008] The cover plate is provided with a second latching part, which is perpendicular to the cover plate body and can be engaged with the first latching part in the vertical direction.

[0009] In one possible implementation, both the base plate and the side plate are provided with a plurality of through holes arranged in an array.

[0010] In one possible implementation, the first reinforcing part, the second reinforcing part, and the first snap-fit ​​part are all arc-shaped.

[0011] In one possible implementation, the top of the side panel is provided with a support portion perpendicular to the side panel, and the support portion abuts against the cover plate.

[0012] In one possible implementation, the base plate and the side plate are integrally formed as a single structure.

[0013] In one possible implementation, the cable tray body is a straight-through type.

[0014] In one possible implementation, the cable tray body is a bend-through type.

[0015] In one possible implementation, the cable tray body is a T-shaped type.

[0016] In one possible implementation, the cable tray body is a four-way type.

[0017] In one possible implementation, a connector is also included for connecting the plurality of the cable tray bodies to each other.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting a first reinforcing part on the base plate and a second reinforcing part on the side plate, the bending resistance, torsion resistance and load-bearing capacity of the base plate and the side plate are improved, thereby improving the structural strength of the cable tray body.

[0033] like Figure 1-3The diagram shows a self-locking reinforced cable tray, comprising a tray body 1 and a cover plate 2. The tray body 1 includes a base plate 11 and a side plate 12. The side plate 12 is connected to the side wall of the base plate 11. The base plate 11 has first reinforcing parts 111 on both sides, which are located close to the side plate 12. The top of the side plate 12 has a second reinforcing part 121 and a first latching part 122 connected together. The cover plate 2 has a second latching part 21, which is perpendicular to the cover plate 2 body. The second latching part 21 can be engaged with the first latching part 122 in the vertical direction. It should be noted that the first reinforcing part 111, the second reinforcing part 121 and the first snap-fit ​​part 122 are all provided along the extension direction of the cable tray body 1. The first reinforcing part 111 is provided on both sides of the bottom plate 11. The first reinforcing part 111 is provided to enhance the bending resistance, torsion resistance and load-bearing capacity of the bottom plate 11, so as to prevent the bottom plate 11 from being deformed by the heavy pressure of the cable. The second reinforcing part 121 can improve the impact resistance of the side plate 12 and prevent the side plate 12 from twisting. The second snap-fit ​​part 21 is formed by bending the side wall of the cover plate 2 downward, and the shape of the second snap-fit ​​part 21 is adapted to the first snap-fit ​​part 122 so that the first snap-fit ​​part 122 and the second snap-fit ​​part 21 are fastened to each other, so that the cover plate 2 closes the cable tray body 1 by pressing.

[0034] The beneficial effects of this utility model are as follows: by providing a first reinforcing part 111 on the base plate 11 and a second reinforcing part 121 on the side plate 12, the bending resistance, torsion resistance and load-bearing capacity of the base plate 11 and the side plate 12 are improved, thereby improving the structural strength of the cable tray body 1. The cover plate 2 and the cable tray body 1 are connected by a self-locking connection through the cooperation of the first snap-fit ​​part 122 and the second snap-fit ​​part 21, thereby improving the convenience of installation / removal of the cover plate 2.

[0035] Please refer to Figure 1 In one possible implementation, both the base plate 11 and the side plate 12 are provided with a plurality of through holes arranged in an array. It should be noted that the through holes in the base plate 11 and the side plate 12 can reduce the temperature rise of the cable, extend the insulation life, and greatly improve the heat dissipation performance of the cable tray. In addition, the through hole design can also facilitate visual inspection by workers, quickly locate fault points, and reduce power outage maintenance time.

[0036] Please refer to Figure 3In one possible implementation, the first reinforcing part 111, the second reinforcing part 121, and the first snap-fit ​​part 122 are all arc-shaped. It should be noted that the first reinforcing part 111 is an upward-protruding arc shape, the second reinforcing part 121 is an inward-protruding arc shape, and the first snap-fit ​​part 122 is an outward-protruding arc shape. The second reinforcing part 121 and the first snap-fit ​​part are generally S-shaped. Therefore, the outer side of the second reinforcing part 121 is recessed to form a groove. The second snap-fit ​​part is also S-shaped, and its inner surface can fit against the outer surfaces of the second reinforcing part 121 and the first snap-fit ​​part, thereby achieving a self-locking connection between the cover plate 2 and the side plate 12. This strengthens the stability of the cable tray, reduces material consumption, reduces production costs, and improves economic efficiency.

[0037] Specifically, the second latching part 21 is formed by bending the cover plate 2, which gives the second latching part 21 a certain elastic deformation performance. When the user presses the cover plate 2, the second latching part 21 can undergo elastic deformation, thereby allowing the second latching part 21 to enter the slide groove, so as to realize the latching between the cover plate 2 and the side plate 12. When disassembling the cover plate 2, the cover plate 2 can be pried open from the side of the cable tray body 1, which is very convenient.

[0038] Please refer to Figure 2 In one possible implementation, a support portion 123 is provided at the top of the side plate 12. The support portion 123 is perpendicular to the side plate 12 and abuts against the cover plate 2. It should be noted that the support portion 123 is formed by extending horizontally inward from the upper part of the side plate 12. The provision of the support portion 123 can significantly improve the mechanical strength of the cable tray body 1, thereby reducing the thickness of the plate material, reducing the self-weight of the cable tray body 1, saving materials and costs, and improving economic efficiency.

[0039] Please refer to Figure 2 In one possible implementation, the base plate 11 and the side plate 12 are integrally formed. It should be noted that the integrally formed structure of the base plate 11 and the side plate 12 is beneficial to improving the structural strength of the cable tray body 1, simplifying the production process, improving production efficiency, and saving production costs. Preferably, the cable tray body 1 can be integrally formed by stamping metal sheet to improve its bending and torsional resistance.

[0040] Please refer to Figure 1In one possible implementation, the cable tray body 1 is a straight-through type. Optionally, the cable tray body 1 extends along its length to form a long strip shape. Correspondingly, the first reinforcing part 111 and the second reinforcing part 121 extend along the length of the cable tray body 1 to adapt to the shape of the cable tray body 1. Furthermore, when the cable tray body 1 is a straight-through type, the cover plate 2 can also slide laterally from the end of the cable tray, allowing the second snap-fit ​​part 21 to slide directly into the groove from the end to complete the installation of the cover plate 2. This is beneficial to improving the installation efficiency of the cover plate 2. When disassembling the cover plate 2, it can be slid out directly or pried open from the side of the cable tray, which is very convenient.

[0041] Please refer to Figure 4 In one possible implementation, the cable tray body 1 is a bend-through type. Optionally, the cable tray body 1 can be a bend-through type, with the bend-through type cable tray body 1 being L-shaped, and the inner corner of the cable tray body 1 being arc-shaped, while the outer corner of the cable tray body 1 is right-angled. Correspondingly, the first reinforcing part 111 and the second reinforcing part 121 located on the inner side are also arc-shaped to achieve the bend-through effect, while the corners of the first reinforcing part 111 and the second reinforcing part 121 located on the outer side are right-angled.

[0042] Please refer to Figure 5 In one possible implementation, the cable tray body 1 is a T-shaped structure. Optionally, the T-shaped cable tray body 1 is T-shaped, in which case the outer side plate 12, the first reinforcing part 111 and the second reinforcing part 121 are straight, and the corners of the inner side plate 12, the first reinforcing part 111 and the second reinforcing part 121 are rounded.

[0043] Please refer to Figure 6 In one possible implementation, the cable tray body 1 is a four-way type. Optionally, the four-way type cable tray body 1 is cross-shaped, in which case the corners on both sides of the cable tray body 1 are rounded.

[0044] It should be noted that the corners of the bend-type, tee-type, and four-way types all adopt smooth arc transitions, thereby eliminating sharp edges, reducing the risk of cable wear, greatly reducing mechanical cutting damage caused during cable laying and operation, which is beneficial to protecting cables, extending cable life, and improving the safety of the cable tray body 1. In addition, the smooth bend makes the cable easier to pull, reduces the tensile stress on the cable, significantly reduces traction resistance, and helps to reduce laying difficulty and labor intensity. In addition, the cable tray body 1 of the bend-type, tee-type, and four-way types is equipped with a corresponding cover plate 2. The cover plate 2 also has a smooth arc and is locked to the cable tray body 1 by self-locking, so that the installation / removal of the cover plate 2 is faster and easier. Furthermore, the first reinforcing part 111 and the second reinforcing part 121 can also bend together with the cable tray body 1, ensuring that the bend of the cable tray body 1 also has sufficient strength and rigidity, significantly enhancing its ability to resist bending and torsional loads, and enabling it to withstand greater loads.

[0045] Please refer to Figure 7 In one possible implementation, a connector 3 is also included, which is used to connect multiple cable tray bodies 1 to each other. It is readily understood that straight-through, bend-through, tee-through, and cross-type cable trays can all be assembled together using the connector 3 to form a complete cable tray system. Furthermore, the bend sections of the bend-through, tee-through, and cross-type cable trays can be designed with various standard radii of curvature to adapt to straight-through cable trays of different widths, greatly improving the versatility of the cable trays. In addition, the connector 3 is also provided with a first reinforcing part 111 to adapt the connector 3 to the cable tray body 1. The connector 3 has multiple through holes. During assembly, two cable tray bodies 1 extend into the connector 3 from both ends, so that the cable tray bodies 1 are located inside the connector 3, and the through holes on the cable tray bodies 1 correspond to the through holes on the connector 3, thereby connecting both ends of the connector 3 to the two cable tray bodies 1 respectively using bolts.

[0046] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
