Description

Technical Field

[0001] The utility model relates to a cable tray, in particular to a cable tray convenient for assembly. Background Art

[0002] A cable tray refers to a structure made of metal or fiberglass, which is divided into trough cable trays, tray cable trays, ladder cable trays, grid cable trays, etc. It consists of brackets, arms and installation accessories, etc. It can be erected independently or laid on various building and pipe gallery brackets, reflecting the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance. All parts need to be galvanized. For the cable tray installed outdoors on the building, if it is near the sea or in a corrosion area, the material must have physical properties of anti-corrosion, moisture resistance, good adhesion and high impact resistance.

[0003] Chinese patent with the patent publication number "CN206894162U" discloses a ladder-type cable tray, which includes two mutually parallel ladder sides and a plurality of crossbars located between the two ladder sides. The ladder side is provided with a first reinforcing groove recessed inward, and the first reinforcing groove extends along the length direction of the ladder side. The lower side of the ladder side is bent inward to form a trailing edge; the crossbar is provided with a second reinforcing groove recessed to one side. The crossbar is erected on the trailing edges of the two ladder sides and is screwed or welded to the trailing edge. The two ends of the crossbar respectively abut against the two ladder sides and are welded to the ladder side.

[0004] In the process of implementing the above patent technology, the inventor found that at least the following problems exist in this technology:

[0005] First, the connection between the two ladder sides and the crossbar is realized by screwing or welding. Screwing is prone to loosening. Due to environmental factors (such as humidity, chemical corrosion, etc.), the bolts and connectors may be corroded, and the corrosion will cause the connection performance to decline or even fail.

[0006] Second, welding will cause deformation and stress concentration, reducing the strength and durability of the welded joint. In addition, the welded joint is easily eroded by corrosion media such as oxidation and sulfidation, accelerating the corrosion rate of the metal, which will reduce the service life of the welded joint.

[0007] Third, cables will be laid on the crossbar. After the crossbar is subjected to the gravity of the cables, the connection between the two ladder sides and the crossbar bears greater stress, and the crossbar is prone to deformation and fracture. Summary of the Invention

[0008] In view of the above situation, in order to solve the technical problems of the prior art, the utility model provides a cable tray convenient for assembly.
