Description
Technical Field
[0001] This utility model relates to the field of cable tray technology, specifically to a cable tray that is easy to clean. Background Technology
[0002] Cable trays are available in various structures, including trough type, tray type, ladder type, and mesh type, and consist of supports, brackets, and installation accessories. Cable trays within buildings can be installed independently or laid on various building and pipe rack supports. They should be characterized by simple structure, aesthetically pleasing appearance, flexible configuration, and convenient maintenance.
[0003] After cable trays are installed, a lot of dust will accumulate on their covers over time. If they are not cleaned, the accumulated dust will be blown off and cause environmental pollution. However, since cable trays are usually installed at high places and are quite long, cleaning requires workers to climb ladders to reach higher places. Each time they climb the ladder, they can only clean the dust in one area of the cable tray. Cleaning the dust on the entire length of the cable tray requires climbing up and down the ladder multiple times and moving the ladder to clean it, which is very inconvenient. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a cable tray that is easy to clean, solving the technical problem that cleaning existing cable trays requires multiple trips to a high place using ladders, which is very inconvenient.
[0005] The present invention provides a cable tray that is easy to clean, comprising: a cable tray body, wherein the cable tray body has an installation cavity for storing cables, and a cover plate is provided on the top of the cable tray body;
[0006] A dustproof cloth is detachably installed on the upper surface of the cover plate. The dustproof cloth is used to prevent dust from falling onto the upper surface of the cover plate. The cover plate has slots on both sides, which extend along the length of the cover plate to the ends of both ends. The dustproof cloth has a rigid rod near the edge of the slot, which is engaged in the slot. The dustproof cloth covers the upper surface of the cover plate through the cooperation of the rigid rod and the slot.
[0007] As a further improvement of this utility model, the slot wall near both ends of the cover plate is provided with a first mounting groove, and a magnetic block is provided in each of the first mounting grooves. Iron sheets are pressed onto the outer surface of the rigid rod at positions corresponding to the magnetic blocks. When the rigid rod and the slot are connected, they are magnetically fixed to each other by the magnetic blocks and the iron sheets.
[0008] As a further improvement of this utility model, each of the two rigid rods near the dustproof cloth has a second mounting groove along its length that is adapted to the length of the dustproof cloth. The edges on both sides of the dustproof cloth are inserted into the second mounting groove, and the joint between the dustproof cloth and the second mounting groove is filled with adhesive.
[0009] As a further improvement of this utility model, the slot is designed with an arc shape, the arc of the slot matches the arc of the outer surface of the rigid rod, and the length of the slot is adapted to the length of the rigid rod.
[0010] As a further improvement of this utility model, a first flange extends from the inner side of the cable tray body near the top, and a second flange extends from both sides of the cover plate in a vertical direction. The cover plate is sleeved on the cable tray body through the second flange.
[0011] As a further improvement of this utility model, the top surface of the first flange is provided with a plurality of first threaded holes through it in the vertical direction, and the upper surface of the cover plate is provided with a second threaded hole through it at a position corresponding to the first threaded holes.
[0012] As a further improvement of this utility model, an annular stepped surface is provided on the inner wall of the second threaded hole near the top, and the top surface of the screw is flush with the top surface of the cover plate after the screw is screwed into the second threaded hole.
[0013] As a further improvement of this utility model, fixing holes are respectively provided on both sides of the cable tray body near the bottom end face. The fixing holes penetrate the cable tray body and are used to fix the cable tray body when installing it.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] In this invention, the dustproof cloth covering the cover plate prevents dust from falling onto the cover plate when it accumulates. Instead, the dustproof cloth catches the dust and allows for easy and quick cleaning when cleaning is needed. Simply grab the rigid bar to remove the entire dustproof cloth covering the cover plate and clean the dust on the cloth. This eliminates the need for multiple trips up and down or moving the ladder, making cleaning convenient and quick. Attached Figure Description

[0027] Please see Figure 1-5 The present invention provides a cable tray that is easy to clean, comprising: a cable tray body 1, the cable tray body 1 having an installation cavity 14 for storing cables, and a cover plate 2 on the top of the cable tray body 1;
[0028] Dustproof cloth 3 is detachably installed on the upper surface of cover plate 2. Dustproof cloth 3 is used to prevent dust from falling onto the upper surface of cover plate 2. The cover plate 2 has slots 21 on both sides. The slots 21 extend along the length of cover plate 2 to the ends of both ends of cover plate 2. The dustproof cloth 3 has a rigid rod 31 near the edge of the slot 21. The rigid rod 31 is inserted into the slot 21. The dustproof cloth 3 covers the upper surface of cover plate 2 through the cooperation of the rigid rod 31 and the slot 21.
[0029] The dustproof cloth 3 refers to a covering layer made of flexible materials, such as nylon cloth, polyester fiber cloth, or fabric with a dustproof coating. Its function is to prevent dust from directly depositing on the surface of the cover plate 2. The rigid rod 31 is a rigid strip structure, which can be made of metal strips (such as aluminum alloy strips) or rigid plastic strips, and is used to provide support for the edges of the dustproof cloth 3 to maintain its flatness. The slot 21 is a groove structure opened on both sides of the cover plate 2. Its cross-sectional shape matches the contour of the rigid rod 31. For example, it can be designed as a U-shaped slot or a dovetail slot. The dustproof cloth 3 can be detachably installed by the snap-fit between the rigid rod 31 and the slot 21. When the rigid rod 31 is fully embedded in the slot 21, the dustproof cloth 3 flatly covers the upper surface of the cover plate 2, forming a dust barrier. This design allows the dustproof cloth 3 to be quickly removed for cleaning or replacement, avoiding long-term accumulation of dust in the gaps of the cable tray structure. At the same time, the way the rigid rod 31 and the slot 21 cooperate ensures that the dustproof cloth 3 is not easily lifted by external force after installation, maintaining the stability of the dustproof effect.
[0030] Please see Figure 4 and Figure 5 In this embodiment, the slot 21 is provided with a first mounting slot 211 at both ends of the slot wall near the cover plate 2. Each of the first mounting slots 211 is provided with a magnetic block 212. Iron sheets 312 are pressed onto the outer surface of the rigid rod 31 at the positions corresponding to the magnetic blocks 212. When the rigid rod 31 and the slot 21 are connected, they are magnetically fixed to the iron sheets 312 by the magnetic blocks 212.
[0031] Two rigid rods 31 are provided with second mounting grooves 311 along their length direction near the dustproof cloth 3, which are adapted to the length of the dustproof cloth 3. The edges on both sides of the dustproof cloth 3 are inserted into the second mounting grooves 311, and the joint between the dustproof cloth 3 and the second mounting grooves 311 is filled with adhesive.
[0032] The slot 21 has an arc-shaped structure design. The arc of the slot 21 matches the arc of the outer surface of the rigid rod 31, and the length of the slot 21 is adapted to the length of the rigid rod 31.
[0033] The magnetic block 212 refers to a magnetic fixing element, such as a permanent magnet (e.g., a neodymium iron boron magnet) or an electromagnet, which is fixed in the first mounting groove 211 by embedding or bonding. The iron sheet 312 is a magnetically conductive metal sheet (e.g., a carbon steel sheet or a silicon steel sheet), which is attached to the outer surface of the rigid rod 31 by a pressing process (e.g., stamping or roll forming). The positional correspondence between the magnetic block 212 and the iron sheet 312 is automatically aligned through the sliding engagement of the slot 21 and the rigid rod 31. When the rigid rod 31 is fully slid into the slot 21, the iron sheet 312 enters the effective adsorption range of the magnetic block 212, and the axial limit of the rigid rod 31 is formed by the magnetic force. Compared with a purely mechanical snap-fit structure, the magnetic fixing method, while ensuring connection reliability, allows the rigid rod 31 to be finely adjusted along the length of the slot 21 to adapt to dimensional changes caused by processing errors or thermal expansion and contraction. Moreover, the rigid rod 31 can be removed by overcoming the magnetic force during disassembly, avoiding structural damage caused by violent disassembly.
[0034] The second mounting groove 311 is a recessed structure formed on the side wall of the rigid rod 31. Its cross-sectional shape matches the edge contour of the dustproof cloth 3 (such as a U-shaped groove or dovetail groove), and it is formed by milling or stamping. After the edge of the dustproof cloth 3 is inserted into the second mounting groove 311, the adhesive (such as epoxy resin or silicone sealant) filled in the groove serves both to fix it and to seal the joint between the dustproof cloth 3 and the rigid rod 31. This connection method is more advantageous than sewing or riveting: the adhesive filling can completely wrap the fibers of the dustproof cloth 3, preventing it from coming undone after long-term use; when the dustproof cloth 3 needs to be replaced, the old cloth can be peeled off by heating to soften the adhesive layer, and the new cloth can be inserted and the adhesive can be applied to reuse the rigid rod 31, significantly reducing maintenance costs. In addition, the design of the second mounting groove 311 running through the length of the rigid rod 31 allows a single rigid rod 31 to be adapted to dustproof cloths 3 of different widths, improving the versatility of the components.
[0035] The curvature of the slot 21 matches the curvature of the outer surface of the rigid rod 31, meaning that the inner wall surface of the slot 21 and the outer surface surface of the rigid rod 31 have the same radius of curvature. For example, when the rigid rod 31 is cylindrical, the slot 21 is designed with a semi-circular cross-section; when the rigid rod 31 is elliptical cylindrical, the slot 21 adopts an elliptical cross-section accordingly. This design allows the rigid rod 31 and the slot 21 to form surface contact rather than line contact, significantly increasing the contact area, dispersing the pressure of the rigid rod 31 on the slot 21, preventing the slot 21 from deforming after long-term use, guiding the rigid rod 31 smoothly into the slot using the guiding effect of the curved surface, and reducing the difficulty of installation; the geometric constraints between the curved surfaces prevent the rigid rod 31 from wobbling radially within the slot 21.
[0036] Please see Figure 1 and Figure 2 It should be noted that a first flange 11 extends from the inner side of the cable tray body 1 near the top, and a second flange 23 extends from both sides of the cover plate 2 in the vertical direction. The cover plate 2 is fitted onto the cable tray body 1 through the second flange 23.
[0037] A plurality of first threaded holes 12 are provided through the top surface of the first flange 11 in a vertical direction, and a second threaded hole 22 is provided through the upper surface of the cover plate 2 at a position corresponding to the first threaded holes 12.
[0038] An annular stepped surface is provided on the inner wall of the second threaded hole 22 near the top. After the screw is screwed into the second threaded hole 22, the top surface is flush with the top surface of the cover plate 2.
[0039] Fixing holes 13 are provided on both sides of the cable tray body 1 near the bottom end. The fixing holes 13 penetrate the cable tray body 1 and are used to fix the cable tray body 1 when installing it.
[0040] The first flange 11 is a plate-like structure extending horizontally from the top inner side of the cable tray body 1 towards the mounting cavity 14. It can be fixedly connected to the cable tray body 1 by integral stamping or welding. The second flange 23 is a folded edge structure extending vertically downward on both sides of the cover plate 2, which is formed by bending. When the cover plate 2 is installed, the second flange 23 is fitted onto the outside of the first flange 11 from top to bottom, forming a wrap-around connection structure. This design uses vertical surface contact between flanges to replace the traditional planar bonding connection method, significantly increasing the contact area to distribute the load borne by the cover plate 2. For example, when the cable is placed in the mounting cavity 14, the second flange 23 can directly transfer part of the load to the side wall of the cable tray body 1 through the first flange 11, avoiding deformation of the cover plate 2 due to long-term pressure.
[0041] The first threaded hole 12 is a threaded through hole perpendicularly penetrating the first flange 11, and its axis coincides with the axis of the second threaded hole 22. After the cover plate 2 is fitted onto the cable tray body 1, the two are mechanically fixed by screwing in a screw. The connection between the screw and the threaded hole can be achieved by directly tapping the thread with a self-tapping screw, or by using a pre-embedded nut to enhance the connection strength. In particular, the annular stepped surface provided in the second threaded hole 22 is used to accommodate the head structure of the screw. When the screw is fully screwed in, its top surface is flush with the upper surface of the cover plate 2, avoiding the screw head protruding and affecting the flat laying of the dustproof cloth 3. Compared with the traditional exposed bolt fixing method, this design not only ensures the reliability of the connection, but also eliminates the risk of interference between the bolt head and the dustproof cloth 3. At the same time, the stepped surface structure can disperse the local pressure of the screw head on the cover plate 2, preventing indentations from forming on the surface of the cover plate 2 after long-term use.
[0042] The fixing hole 13 is a through hole formed at the bottom of the side wall of the cable tray body 1, with its axis perpendicular to the length direction of the cable tray body 1. It can be formed by punching or drilling. The design of the fixing hole 13 penetrating both sides of the cable tray body 1 allows expansion bolts or welded studs to be inserted and fixed from the outside of the cable tray. For example, when installing on a concrete wall, expansion bolts can be passed through the fixing hole 13 and anchored to the wall to achieve stable installation of the cable tray body 1. Compared with the single-sided fixing hole 13 design, the double-sided through structure allows the cable tray body 1 to adapt to the needs of installation in both forward and reverse directions, especially in confined spaces where fixing can be completed without adjusting the direction of the cable tray.
[0043] When dust removal is required, climb the ladder to a higher position, grab the two rigid rods 31 from one end, use the rigid rods 31 to lift the dustproof cloth 3, and pull the two rigid rods 31 together to concentrate the dust on the dustproof cloth 3. After removing the dustproof cloth 3, wipe and clean the dust on the dustproof cloth 3. After cleaning, reinstall the dustproof cloth 3 back on the top of the cover plate 2. When installing, align the rigid rods 31 with the slots 21 and insert them, and use the magnetic blocks 212 and iron plates 312 for magnetic fixation.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
