Description

Technical Field

[0001] This utility model belongs to the field of cable tray technology, specifically relating to a cable tray connection structure based on angle adaptive adjustment. Background Technology

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

[0003] Existing cable tray connection structures mostly adopt an integrated fixed connection structure. During on-site installation, they cannot be adjusted according to the installation angle of the cable tray. For cable trays installed at special angles, it is necessary to develop and process cable tray connection structures suitable for special angles, which increases production costs. Therefore, we propose a cable tray connection structure based on angle adaptive adjustment. Utility Model Content

[0012] A limiting slot is formed on the outer guide limiting strip at the position corresponding to the inner guide limiting strip. A first limiting block is provided on one end of the inner guide limiting strip facing the outer guide limiting strip. The first limiting block is limited and engaged in the limiting slot. The first limiting block and the limiting slot form a limiting and guiding function.

[0013] The second limiting block is provided at one end of the inner guide limiting strip away from the outer guide limiting strip, and the second limiting block and one end of the outer guide limiting strip form a limiting function.

[0014] Preferably, the upper surface of the second limiting block is flush with the upper surface of the outer guide limiting strip.

[0015] Preferably, the inner guide limiting strip has threaded holes that are evenly spaced.
