Description

Technical Field

[0001] This utility model belongs to the field of wire trough technology, and in particular relates to a novel aluminum alloy wire trough. Background Technology

[0002] Cable trays are commonly used in the electrical distribution industry and are also a common building material in the renovation market. They come in many specifications and are widely used in electrical engineering projects and home decoration. Currently, the most common cable trays on the market are made of PVC plastic, followed by galvanized iron. Because their appearance is similar to the wall, PVC cable trays are generally used in home decoration. However, after a period of use, their surface will oxidize and yellow. Furthermore, excessively high temperatures in certain areas can cause localized deformation of the cable trays. The yellowing and deformation problems seriously affect the visual appeal to users. Using aluminum alloy cable trays can avoid these problems. However, most existing aluminum alloy cable trays are made using an extrusion process. Compared to galvanized iron cable trays made using a stamping process and PVC cable trays made using an injection molding process, their waterproofing ability is relatively insufficient. Water is difficult to drain after entering the cable tray, affecting its performance and lifespan. Summary of the Invention

[0003] Based on the aforementioned problems in the existing technology, this utility model provides a novel aluminum alloy wire trough, including a trough body and a trough cover fitted onto the trough body. The bottom surface of the trough body has a structure that is high in the middle and slopes downward on both sides. Both sides of the bottom surface of the trough body are provided with downwardly recessed water troughs. Drilling positioning grooves are provided on the water troughs. A first hollow leg is provided on the inner side below the water trough, and a second hollow leg is provided on the outer side below the water trough. The length of the first hollow leg is greater than that of the second hollow leg.

[0004] The sidewalls and bottom of the trough are both double-layered hollow structures, and several supporting ribs are provided inside the cavity of the hollow structure. The second overhead leg extends downward from the sidewall.

[0005] The sidewall of the groove is provided with several single-layer openings, and the openings are also provided with drilling positioning grooves.

[0006] The upper part of the side wall of the groove is provided with a slot for snapping on the groove cover. The part of the side wall of the groove above the slot is concave inward, and the concave distance is equal to the thickness of the hook of the groove cover. The upper side of the slot opening is rounded or chamfered.

[0007] The groove cover includes a cover body, and hooks matching the groove are provided on both sides of the lower surface of the cover body. The groove cover is closed onto the groove body by the cooperation of the hooks and the groove.

[0008] The cover is an isosceles triangular prism with the apex at the top. The two sides of the cover extend outward beyond the sidewalls of the tank to form protrusions. The outer ends of the protrusions are provided with downward-extending water inlets.

[0009] The cover is a hollow structure, and a support rib is provided at the top corner of the cavity of the hollow structure. One end of the support rib is connected to the top of the cover, and the other end is connected to the bottom of the cover.

[0010] The cover is straight and its width is equal to that of the groove. The hooks are located on both sides of the cover.

[0011] The lower surface of the cover is provided with several downward-protruding reinforcing ribs.

[0012] The first overhead leg is provided with a limiting groove for engaging with the hanger.

[0013] The beneficial effects of this utility model are as follows: the bottom surface of the tank is designed with a high middle and low sides, which can guide water to the water tanks on both sides. In the water tank, drainage holes can be opened as needed by drilling positioning grooves to drain the water in the water tank. Combined with the setting of the overhead legs, it can not only avoid the drainage holes being blocked by the ground and affecting drainage, but also prevent water from the ground from seeping upward into the water tank, thus avoiding affecting the use effect and service life of the cable tray.

[0026] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0027] Example 1:

[0028] As attached Figure 1-7 The illustration shows a novel aluminum alloy cable tray, comprising a tray body 1 and a tray cover 2 fitted onto the tray body 1. The sidewalls and bottom of the tray body 1 are both double-layered hollow structures. A supporting rib 3 is installed within the cavity of one section of the hollow structure on the sidewall, and three supporting ribs 3 are installed within the cavity of the hollow structure on the bottom. Aluminum alloy has excellent corrosion resistance, but it is relatively soft and prone to natural bending when the span is large. The double-layered cavity structure, combined with the supporting ribs 3, greatly improves the strength of the aluminum alloy and reduces the natural bending of the cable tray. The bottom of the tray body 1 has a structure that is high in the middle and slopes downwards on both sides. Supports are installed on both sides of the bottom of the tray body 1. There is a recessed water tank 4, which is a single-layer structure and is equipped with a drilled positioning groove 5. Depending on the actual needs, a number of drainage holes 6 can be opened at different locations, or no drainage holes 6 can be opened (such as when used indoors), making it more convenient and flexible to use. When selecting a cable tray, the appropriate specification and size of the cable tray should be selected according to the diameter of the cable to avoid the cable falling into the water tank 4 as much as possible. The inner side of the bottom of the water tank 4 is equipped with a first hollow leg 7, and the outer side of the bottom of the water tank 4 is equipped with a second hollow leg 8 extending downward from the side wall. The length of the first hollow leg 7 is greater than that of the second hollow leg 8, which can prevent water from flowing to the inner side of the bottom of the water tank 4. The side wall of the groove 1 is also provided with two single-layer openings 9, and the openings 9 are also provided with drilling positioning grooves 5. Similarly, the number of heat dissipation holes 10 can be opened at different positions or not opened at all, depending on actual needs. The upper part of the side wall of the groove 1 is provided with a slot 11 for snapping on the groove cover 2. The part of the side wall of the groove 1 above the slot 11 is concave inward, and the distance of the concavity is equal to the thickness of the hook 16 of the groove cover 2. The upper side of the opening of the slot 11 is rounded to facilitate the hook 16 to snap into the slot 11.

[0029] The trough cover 2 includes a cover body 12, which is a hollow isosceles triangular prism structure with the apex located at the top. The two sides of the cover body 12 extend outward beyond the sidewall of the trough body 1 to form protrusions 13. The outer ends of the protrusions 13 are provided with downwardly extending water inlet portions 14. The hollow cavity is provided with a top support rib 15 at the apex. One end of the top support rib 15 is connected to the top of the cover body 12, and the other end is connected to the bottom of the cover body 12. The lower surface of the cover body 12 is provided with hooks 16 that match the slots 11. The trough cover 2 is closed onto the trough body 1 by the cooperation of the hooks 16 and the slots 11.

[0030] The aluminum alloy cable tray provided in this embodiment is suitable for outdoor use. The pointed top and outward-extending cover 2 can block most of the rainwater and guide it to the sides, allowing it to drip directly to the ground from the water inlet 14. A small amount of water blown in by the wind or seeping into the cable tray from the joint gaps will gradually flow into the water tanks 4 on both sides and be discharged from the drain holes 6, preventing water accumulation in the cable tray and avoiding affecting the performance and service life of the cable tray due to water accumulation.

[0031] Example 2:

[0032] The difference between this embodiment and Embodiment 1 lies in the structure of the cover 12, as shown in the attached figure. Figure 8-12 As shown, the cover 12 is straight and its width is equal to that of the groove 1. The groove cover 2 and the groove 1 have the same width, which can avoid affecting the installation of the hanger and also has a simpler appearance. The hooks 16 are set on both sides of the cover 12. The lower surface of the cover 12 is provided with seven downward protruding reinforcing ribs 17. In addition, the first bracket leg 7 is provided with a limiting groove 18 for engaging and limiting with the hanger.

[0033] The aluminum alloy cable tray provided in this embodiment is suitable for indoor hanging installation. According to the width of the hanger, a suitable limiting groove 18 is milled on the first empty leg 7 to limit the relative displacement of the cable tray and the hanger in the horizontal direction. No bolts are required for installation, which is convenient for installation and disassembly and will not damage the cable tray.

[0034] The aluminum alloy cable tray provided in this embodiment is suitable for indoor hanging installation. A suitable limiting groove is milled on the first empty leg according to the width of the hanger, which can limit the relative displacement of the cable tray and the hanger in the horizontal direction. No bolts are required for fixing and installation, which is convenient for installation and disassembly and will not damage the cable tray.

[0035] The above-described embodiments only illustrate two implementation methods of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
