Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, specifically to a cable tray with adjustable length. Background Technology

[0002] Cable trays are classified into various structures such as trough type, tray type, ladder type, and mesh type, and consist of supports, brackets, and installation accessories. Cable trays inside buildings can be installed independently or laid on various building and pipe rack supports. They should be characterized by simple structure, beautiful appearance, flexible configuration, and convenient maintenance. All parts must be galvanized. Cable trays installed outdoors are also permitted.

[0003] Cable trays cannot be adjusted in length during use. Therefore, to address this issue, a Chinese patent discloses a length-adjustable cable tray (publication number: CN220857539U). The technical problem is that when adjusting the length of a cable tray with a long distance between the expansion joint and the cable tray, misalignment occurs between the top surface of the expansion joint and the top surface of the cable tray due to gravity. The technical solution is a length-adjustable cable tray comprising a middle section assembly and a cantilever mounting assembly. This invention uses a bidirectional connecting rod to allow the adjusting and fixing structures to be positioned in both directions, thus balancing the pressure received by the expansion joint. This addresses the problem of misalignment between the top surface of the expansion joint and the top surface of the cable tray due to gravity when adjusting the length of the cable tray where the distance between the expansion joint and the cable tray is long. This significantly improves the overall safety of the cable tray. However, while this patent can solve the problem of adjusting the length of the cable tray where the distance between the expansion joint and the cable tray is long, it is inconvenient for users to operate. It requires bidirectional positioning, which is inconvenient for users and wastes a lot of time. Utility Model Content

[0029] As a technical optimization of this utility model, by setting up a cable tray 1, the cable can be protected. The user passes the cable through the inside of the cable tray housing 102, and then fixes the cable tray housing 101 on the surface of the cable tray housing 102. After completion, the connecting groove 104 is opened on the right side of the cable tray housing 101, and then the insertion shell 103 is installed on the left side of the extension sleeve 21.

[0030] refer to Figure 3 The extension mechanism 2 includes an extension sleeve 21. The left side of the extension sleeve 21 is fixedly connected to the insertion shell 103. The top and bottom of the front and back sides of the inner wall of the extension sleeve 21 are provided with sliding grooves 22. The sliding grooves 22 are slidably connected to the inside of the sliding block 31. The front and back sides of the extension sleeve 21 are provided with positioning holes 23. The positioning holes 23 are connected to the sliding grooves 22. The right side of the sliding block 31 is fixedly connected with a positioning rod 24. The right side of the positioning rod 24 is fixedly connected to the bridge frame housing 101.

[0031] As a technical optimization of this utility model, by setting the extension mechanism 2, the length of the cable tray housing 101 can be increased. The user first fixes the positioning rod 24 on the left side of the cable tray housing 101, and then puts the extension sleeve 21 on the surface of the cable trough housing 102, so that the positioning rod 24 is inserted into the sliding groove 22, thereby facilitating the user's use.

[0032] refer to Figure 2 The surface of the cable tray housing 101 is fixedly connected to an anti-slip plate 4, and the surface of the extension sleeve 21 is fixedly connected to a protective sleeve 5.

[0034] refer to Figure 1 The front and back of the insertion shell 103 are provided with through holes 6, and the front and back of the inner wall of the connecting groove 104 are provided with square connecting holes 7.

[0035] As a technical optimization of this utility model, by setting through hole 6 and square connecting hole 7, square buckles can be inserted into the interior of insertion shell 103 and connecting groove 104 to prevent the insertion shell 103 and connecting groove 104 from separating.

[0036] refer to Figure 3 The top and bottom of the sliding groove 22 are provided with sliding grooves 8, and the sliding slider 9 is slidably connected inside the sliding groove 8. The side of the sliding slider 9 near the sliding block 31 is fixedly connected to the sliding block 31.

[0037] As a technical optimization of this utility model, by setting the sliding groove 8 and the slider 9, the sliding groove 22 can be fixed to prevent the sliding block 31 from shifting when moving.

[0038] The working principle and usage process of this utility model are as follows: When in use, the user first passes the cable through the inside of the cable tray housing 102, and then pulls the extension sleeve 21 to the left. The extension sleeve 21 increases the length of the cable tray housing 102 and the cable tray housing 101, so that the insertion shell 103 is inserted into the connecting groove 104 of another cable tray 1. The insertion shell 103 can be fixed inside the connecting groove 104 by the square buckle, so that the two cable trays 1 are connected. After completion, the clamping plate 34 is aligned with the positioning hole 23. Then, the rotating rod 33 is passed through the positioning hole 23 and the mating hole 35 by the rotating disk 32, so that the clamping plate 34 is inserted into the sliding block 31. Then, the rotating disk 32 is rotated. The rotating disk 32 drives the clamping plate 34 to rotate 90° through the rotating rod 33. The clamping plate 34 and the rotating disk 32 fix the rotating rod 33. The rotating rod 33 fixes the extension sleeve 21 through the positioning hole 23 and the mating hole 35 to prevent the extension sleeve 21 from moving left and right.

[0039] In summary, this adjustable-length cable tray increases the length of the cable tray 1 by setting an extension mechanism 2, and then fixes the extension mechanism 2 by a fixing mechanism 3 to prevent the extension mechanism 2 from resetting. Users do not need to perform bidirectional positioning during use, which is convenient for users and saves a lot of time.
