Description

Technical Field

[0001] This utility model belongs to the field of cable tray technology, specifically relating to a locking device for steel cable trays. 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 inside buildings can be installed independently or laid on various building structures and pipe rack supports. They are characterized by their aesthetically pleasing appearance, flexible configuration, and convenient maintenance. All parts must be galvanized. For cable trays installed outdoors, the locking mechanism is a fixing device used to secure the cover to the cable trough. Duckbill clips are widely used in cable trays because they are easy to open during subsequent maintenance.

[0003] The existing steel cable tray locking devices have their locking clips directly welded to both sides of the cable tray. However, in actual installation, due to spatial structure, building shape, pipeline laying, and other reasons, and because the welding position of the locking clips is fixed and cannot be flexibly moved and adapted, there are often situations where the cable tray locking clips are blocked, making it difficult to open the cable tray cover later and causing trouble for maintenance work. Utility Model Content

[0004] The purpose of this utility model is to provide a steel cable tray locking device. The first latch can be movably engaged with the sliding strips on both sides of the cable tray through the clamp plate, so that the position of the latch can be adjusted arbitrarily. The structure is flexible and avoids the spatial building structure from obstructing the second latch, thus avoiding affecting the opening and closing of the latch cover in subsequent work. Moreover, the engagement of the clamp rod and the baffle can prevent the second latch from accidentally popping open, thereby enhancing the tightness of the latch.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A steel cable tray locking device includes a cover that is movably fastened to the top of a cable trough. Sliding strips are fixedly connected to both outer walls of the cable trough in a mirror-symmetrical manner. Several hooks are fixedly connected at equal intervals on both sides of the cover. A hanging plate is movably fitted onto the outer walls of two hooks. A first latch is movably arranged on both sides of the cable trough. A second latch is rotatably connected to one end of the first latch. A clamping rod is detachably held at one end of the hanging plate. A baffle is fixedly connected to one end of the second latch. One end of the clamping rod is movably fitted into the baffle. A clamping plate for movably fastening with the two sliding strips is fixedly connected to one side of the first latch in a mirror-symmetrical manner.
