Description

Technical Field

[0001] This utility model relates to the field of communication cabinet technology, specifically to a cable tray structure for a communication cabinet. Background Technology

[0002] Communication cabinets are standard rack-mount structures used for the centralized installation and protection of communication equipment. They are typically made of high-strength cold-rolled steel or aluminum alloy, offering excellent shock resistance, dustproofing, and heat dissipation. The cable tray structure within the cabinet is a core component for cable management, and its design directly affects cable neatness, heat dissipation efficiency, and ease of maintenance. Traditional cable tray structures usually confine cables within the tray using covers, offering little additional support. Furthermore, the cable tray structure is typically made of plastic, which has relatively low strength. This allows the cable tray to deform under the tension of bent cables, impacting ease of maintenance. Utility Model Content

[0003] The purpose of this utility model is to provide a cable tray structure for communication cabinets, in order to solve the problems mentioned in the background art. Traditional cable tray structures usually restrict cables in the tray by using a cover plate. The cables do not have any other fixing structure in the tray, and the cable tray structure is usually made of plastic, which has low strength. This causes the cable tray to deform when subjected to the tension of bent cables, affecting the convenience of later maintenance.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a communication cabinet cable tray structure, including a box body, a cover at the upper end of the box body, a small window and a large window sequentially provided on the side wall of the box body, a process opening at the position corresponding to the large window on the lower wall of the box body, bolt holes sequentially provided on both sides of the process opening on the lower wall of the box body, a limiting member provided on the inner surface of the lower wall of the box body at the position corresponding to the small window, the two ends of the limiting member being fixedly connected to the bolt holes by fixing bolts, and a limiting groove provided on the upper surface of the limiting member between the two fixing bolts.

[0005] Preferably, the box body is made of plastic with a U-shaped cross-section. The upper edge of the side wall of the box body is recessed inward with a snap-fit ​​groove. The lower edge of the side wall of the cover body is recessed inward with a snap-fit ​​seat corresponding to the snap-fit ​​groove. The snap-fit ​​seat snaps into the snap-fit ​​groove. The upper surface edge of the cover body is provided with a chamfered transition.

[0006] Preferably, the upper surface of the limiting member has grooves at both ends corresponding to the fixing bolts, the fixing bolts are disposed inside the grooves, the upper edge of the limiting groove has an arc transition, and the limiting member has guide protrusions inside the limiting groove and on both sides of the limiting groove.

[0007] Preferably, the limiting member and the limiting groove are arranged at a perpendicular angle to the box body between the two small windows.

[0008] Preferably, the lower end of the fixing bolt passes through the limiting member and the box body and extends to the bottom of the box body.

[0009] Compared with the prior art, the beneficial effects of this utility model are: based on the traditional cable tray structure that restricts the cable in the tray by using a cover plate, a limiting member is set inside the cable tray. The limiting member serves as a fixing structure for the cable in the tray. By passing the cable through the limiting member, the cable is fixed to the limiting member, avoiding the deformation of the cable tray structure, which is usually made of plastic, after being subjected to the tension of the bent cable, thus ensuring convenient maintenance in the later stage.

[0016] 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.

[0017] Please see Figure 1-5This utility model provides a cable tray structure for a communication cabinet, including a box body 1. The upper end of the box body 1 is provided with a cover body 2. The side wall of the box body 1 is provided with a small window 3 and a large window 4 in sequence. The lower wall of the box body 1 has a process opening 5 at the position corresponding to the large window 4. The lower wall of the box body 1 has bolt holes 6 in sequence on both sides of the process opening 5. The inner surface of the lower wall of the box body 1 is provided with a limiting member 7 at the position corresponding to the small window 3. The two ends of the limiting member 7 are fixedly connected to the bolt holes 6 by fixing bolts 8. The upper surface of the limiting member 7 is provided with a limiting groove 9 between the two fixing bolts 8.

[0018] In use, by passing the fixing bolt 8 through the limiting member 7 and the bolt hole 6, the structure of the box 1 is fixedly installed inside the communication cabinet. At the same time, the fixing bolt 8 fixes the limiting member 7 inside the box 1 and the box 1 inside the communication cabinet. The cables inside the communication cabinet are sequentially threaded into the box 1 through the small window 3, the large window 4 and the process port 5. The cables are then organized inside the box 1. The limiting groove 9 opened inside the limiting member 7 is used to fasten the cables to the limiting member 7, thereby fixing the cables inside the box 1. A cover 2 is installed at the top of the box 1 to protect the box 1 and ensure its cleanliness.

[0019] The box body 1 is made of plastic with a U-shaped cross-section. The upper edge of the side wall of the box body 1 is recessed with a snap-fit ​​groove 10. The lower edge of the side wall of the cover body 2 is recessed with a snap-fit ​​seat 11 corresponding to the snap-fit ​​groove 10. The snap-fit ​​seat 11 snaps into the snap-fit ​​groove 10. The upper surface edge of the cover body 2 is provided with a chamfer transition 12. Through the snap-fit ​​groove 10 and the snap-fit ​​seat 11, the cover body 2 is snapped onto the upper end of the box body 1. The chamfer transition 12 at the edge of the cover body 2 is provided to avoid the sharp part of the cover body 2 from scratching the cable.

[0020] The upper surface of the limiting member 7 has grooves 13 at both ends corresponding to the fixing bolts 8. The fixing bolts 8 are disposed inside the grooves 13. The upper edge of the limiting groove 9 has an arc transition 14. The limiting member 7 has guide protrusions 15 inside and on both sides of the limiting groove 9. The grooves 13 on the limiting member 7 are provided to house the fixing bolts 8 inside the grooves 13, avoiding scratches to the cable caused by the protruding fixing bolts 8. The arc transition 14 at the upper edge of the limiting groove 9 is provided to avoid scratches to the cable caused by the sharp part of the limiting groove 9. The guide protrusions 15 on both sides of the limiting groove 9 are provided to guide the cable passing through the limiting groove 9, ensuring smooth passage.

[0021] The limiting member 7 and the limiting groove 9 are arranged at a perpendicular angle to the box body 1 between the two small windows 3. The limiting member 7 is arranged perpendicular to the box body 1 to ensure that the cable can be tied horizontally.

[0022] The lower end of the fixing bolt 8 passes through the limiting member 7 and the box body 1 and extends to the bottom of the box body 1. The fixing bolt 8 passes through the box body 1, thereby fixing the box body 1 inside the cabinet.
