Description

Technical Field

[0001] This utility model belongs to the field of cable tray technology, specifically relating to a four-wire box cable tray. Background Technology

[0002] In engineering construction, cable trays are generally used to support and protect cables. Cable trays include components such as straight sections, bends, tees, and crosses, as well as supporting parts such as brackets and hangers. A well-designed cable tray system can effectively ensure the progress and quality of cable laying, facilitate cable inspection, extraction, and replacement throughout its lifespan, and also make the cable laying more aesthetically pleasing, thus enhancing the project's external appearance.

[0003] Existing cable trays mostly use fixed-size wire troughs or cable ties to secure wire harnesses, which are difficult to accommodate wire harnesses of different diameters. Thin wire harnesses are prone to shifting, while excessively thick wire harnesses can have their insulation layer damaged due to compression, directly affecting electrical safety. Furthermore, when wire harnesses are not effectively categorized and secured, they easily become tangled, creating a complex layout. During maintenance, each wire harness must be individually untangled, which is time-consuming, labor-intensive, and poses a risk of accidental contact. Therefore, a four-box cable tray is needed to help solve this problem. Utility Model Content

[0025] 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.

[0026] This specific embodiment is a four-wire cable tray, such as... Figure 1-4 As shown, the four-wire cable tray includes a cable tray body 1, which has an internal cavity. The cable tray body 1 is cross-shaped, and the cross-shaped cable tray structure of the cable tray body 1 arranges the wire harnesses according to their direction, avoiding cross-entanglement of wire harnesses in different directions, facilitating quick identification of wire harness paths during subsequent maintenance, and improving maintenance efficiency. Ventilation holes 8 are provided at the bottom of the cavity. The equidistant design of the ventilation holes 8 effectively promotes heat dissipation of the wire harnesses. At the same time, the closed structure of the cable tray body 1 prevents external moisture or dust from entering, ensuring a stable operating environment for the wire harnesses. A positioning component 9 for auxiliary wire harness fixing is installed in the cavity. The positioning component 9 includes a snap-fit ​​plate 10, which has a U-shaped plate structure. A clamping plate 11 is snap-fitted onto the snap-fit ​​plate 10. A clamping groove 12 for fixing the wire harness is provided on the clamping plate 11. Positioning holes 101 are provided on both sides of the snap-fit ​​plate 10 and the clamping plate 11. A positioning bolt 14 is threaded onto the cable tray body 1, and one end of the positioning bolt 14 is inserted into the positioning hole 101.

[0027] The positioning component 9 can stably clamp and install wire harnesses of different sizes into the corresponding clamping grooves 12 during operation, which can avoid the situation where the wire harnesses inside the cavity are messy and inconvenient for subsequent maintenance during subsequent operation.

[0028] The aforementioned snap-fit ​​plate 10 has symmetrically protruding positioning pins 13 at its four bottom corners. The positioning pins 13 are inserted and installed on the cable tray body 1. Through the positioning pins 13, the snap-fit ​​plate 10 can be stably snapped and installed in the corresponding position during installation, which can achieve the initial positioning and fastening of the snap-fit ​​plate 10 and avoid the snap-fit ​​plate 10 from being misaligned after receiving the cable harness.

[0029] The cable tray body 1 has an overlap groove 2 on its outer edge. A top cover 3 is provided on the top of the cable tray body 1 corresponding to the overlap groove 2. A fixing component 4 for fixing the top cover 3 is installed on the outer edge of the cable tray body 1 and the top cover 3. The fixing component 4 includes a hinge seat 5 fixed on the cable tray body 1. A pressing plate 6 is hinged on the hinge seat 5. A hanging ring 7 is installed on the outer edge of the middle section of the pressing plate 6. The hanging ring 7 is U-shaped. A hook 41 is fixed on the outer edge of the top cover 3. The hook 41 is J-shaped and is fixed with the hanging ring 7.

[0030] By using the fixed component 4, the hanging ring 7 is attached to the hook 41 on the outer edge of the top cover 3. Pressing the pressing plate 6 of the fixed component 4 causes it to rotate around the hinge seat 5. Through the lever principle, the top cover 3 and the cable tray body 1 are tightly closed, which can completely cover the cavity after the top cover 3 is covered, preventing personnel from accidentally touching the live wire harness. At the same time, it can be convenient to disassemble the top cover 3 during subsequent maintenance, which facilitates the quick maintenance of the wire harness.

[0031] Working principle:

[0032] The cable tray body 1 adopts a cross-shaped structure with an internal cavity, which can classify and arrange wire harnesses with different directions in the four arms of the cross, realizing the zoned management of wire harnesses; the ventilation holes 8 are equally spaced at the bottom of the cavity, which assists in the heat dissipation of the wire harnesses through air convection and avoids heat accumulation.

[0033] The snap-fit ​​plate 10 of the positioning component 9 is initially positioned by inserting it into the cable tray body 1 through the bottom positioning pin 13, and then the positioning bolt 14 is screwed into the positioning hole 101 on the side of the snap-fit ​​plate 10 to complete the secondary fixation; the clamping plate 11 is snapped into the U-shaped groove of the snap-fit ​​plate 10, and the positioning bolt 14 is rotated to screw into the positioning hole 101 on the side of the clamping plate 11 to complete the positioning and fastening treatment of the clamping plate 11 and the snap-fit ​​plate 10. The clamping groove 12 directly presses the wire harness to prevent the wire harness from moving.

[0034] After the top cover 3 covers the overlapping groove 2 on the top of the cable tray body 1, press the pressing plate 6 of the fixing component 4 to make it rotate around the hinge seat 5, and hang the hanging ring 7 on the hook 41 on the outer edge of the top cover 3. The top cover 3 and the cable tray body 1 are tightly closed through the lever principle.

[0035] The top cover 3 covers the top of the cable tray body 1 to prevent external dust or foreign objects from entering the cavity. When maintenance is required, simply press the press plate 6 to disengage the hanging ring 7 from the hook 41, and the top cover 3 can be quickly lifted for operation.

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
