Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, specifically to an anti-slip locking structure for cable trays. Background Technology

[0002] Cable trays are categorized into various structures such as trough-type, tray-type, ladder-type, and mesh-type cable trays, and consist of supports, brackets, and installation accessories. They can be installed independently or laid on various building structures and pipe rack supports, featuring simple structure, aesthetically pleasing appearance, flexible configuration, and convenient maintenance. All parts must be galvanized. For cable trays installed outdoors, especially near the sea or in corrosive areas, the material must possess properties such as corrosion resistance, moisture resistance, good adhesion, and high impact resistance.

[0003] Chinese patent document CN211605990U discloses a cable tray structure, specifically a locking structure and cable tray, used to connect a trough and a cover. The locking structure includes two extended grooves fixed to the cover, with two opposing clips fixed to the inner wall of each extended groove. The trough has protrusions adapted to the clips, each clip being S-shaped and made of elastic material. The protrusions are cylindrical, and when the two clips contact, they form an arc-shaped groove for the protrusions. This invention features a novel design. The extended grooves clamp the two vertical ends of the trough, preventing deformation and loosening of the clamps. The clips engage with the protrusions on the trough. The S-shaped design of the clips facilitates insertion of the protrusions, and only a small amount of force is needed to remove the cover, making it convenient to use.

[0004] The existing technology mentioned above cannot quickly limit and lock the cable tray at the upper end of the support platform, which makes it easy for the cable to slide and shift when laying cables. Therefore, it is necessary to develop a cable tray anti-slip locking structure. Utility Model Content

[0005] The purpose of this utility model is to provide a cable tray anti-slip locking structure to solve the problem mentioned in the background art that the existing technology cannot quickly limit and lock the cable tray at the upper end of the support platform, which leads to the slippage and displacement phenomenon when laying cables on the platform.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cable tray anti-slip locking structure, comprising a cable tray support, a support column fixedly connected to the lower end of the cable tray support via a bracket structure, an anti-slip locking mechanism installed between the support column and the cable tray support, a locking sleeve installed on the anti-slip locking mechanism, a ratchet structure installed on the outer surface of the locking sleeve, a locking control handle connected to the locking sleeve via the ratchet structure, a first pull rod installed at the upper end of the locking sleeve, and a second pull rod installed at the lower end of the locking sleeve. The upper end of the first pull rod is connected to the cable tray support via a locking engagement piece, and the lower end of the second pull rod is fixedly connected to a locking block on the surface of the support column via a locking engagement piece.

[0007] Preferably, one end of both the first and second pull rods is provided with a retaining ring structure.

[0008] Preferably, the first pull rod is connected to the locking engagement member via a first locking ring, and the lower end surface of the locking engagement member is provided with a locking hole structure, and the locking ring structure is correspondingly connected and fixed to the first locking ring.

[0009] Preferably, the upper end of the locking engagement component is provided with a C-shaped groove, and the locking engagement component is engaged and fixed with the cable tray support through the C-shaped groove. The upper end of the locking engagement component is provided with a locking pressing part, and the locking pressing part is tightly fitted with the upper surface of the cable tray support.

[0010] Preferably, the second pull rod is connected to the second locking ring via a snap ring structure.

[0011] Preferably, the lower end of the second locking ring is locked and fixed to the locking member.

[0012] Preferably, a fixed base is installed at the lower end of the support column, and a protective rib is provided at the connection between the fixed base and the support column.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention utilizes a locking control handle to drive a ratchet structure that rotates the locking sleeve, thereby causing the control lever structure to tighten inward. This ensures that the C-shaped slot on the locking engagement piece engages more firmly with the locking pressing part, locking and fixing the cable tray support more securely. This further improves the installation stability of the cable tray. Through a convenient assembly design of the internal components of the anti-slip locking mechanism, it has the advantages of simple and convenient installation and fixing, tight and stable connection, and convenient operation.
