Description

Technical Field

[0001] This invention relates to the field of cable trays, specifically to a bend component for an aluminum alloy cable tray. Background Technology

[0002] Aluminum alloy 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 should feature simple structure, aesthetically pleasing appearance, flexible configuration, and convenient maintenance. All parts must be galvanized. Cable trays installed outdoors are also permitted.

[0003] In the existing technology, after the aluminum alloy cable trays are connected end to end, the cable wires are passed through the aluminum alloy cable trays to protect the cable wires. At the corner of the wall, a bend component is used to connect two sets of aluminum alloy cable trays. That is, after one end of the aluminum alloy cable tray and one end of the bend component are inserted, bolts are passed through the reserved openings on the surfaces of the aluminum alloy cable tray and the bend. After the bolts are tightened, the aluminum alloy cable tray and the bend are fixed.

[0004] However, when connecting aluminum alloy cable trays and bends, construction workers need to climb ladders and stand in the air to operate, and they need to use one hand to hold the bolts while using a wrench to tighten the bolts with the other hand. As a result, the construction workers cannot support the anti-fall structure with both hands, which poses a safety hazard. Summary of the Invention

[0005] The purpose of this invention is to provide a bending component for aluminum alloy cable trays to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a bend component for an aluminum alloy cable tray, comprising a bend frame, wherein a connecting plug is movably inserted into the surface of the bend frame for connecting the aluminum alloy cable tray and the bend frame, a pushing mechanism is slidably connected to the surface of the bend frame, and the pushing mechanism is pushed to compress the connecting plug to move, a limiting clip is provided between the pushing mechanism and the connecting plug to limit the pushing mechanism, and a sliding limiting component and an anti-detachment traction component are provided between the pushing mechanism and the bend frame.

After the pushing frame is pushed to block one end of the connecting plug, one end of the connecting plug extends into the clamping groove. Squeezing the pushing block will push the connecting plug to disengage from the clamping groove. When the pressing piece moves with the pushing block, it squeezes the rubber clamping block.

The buckling groove is opened on the side plate of the pushing frame. The limiting frame is in a "C"-shaped plate structure. The limiting frame is fixed on the surface of the bent-through frame. The pushing frame is located between two parallel side plates of the limiting frame. The embedding groove is opened on the surface of the limiting frame. There are multiple embedding grooves, and all the multiple embedding grooves are on the plate body between the two side plates of the limiting frame. The rubber clamping strip is fixed on the surface of the rubber clamping strip, and the rubber clamping strip protrudes towards the buckling groove into the embedding groove, and the rubber clamping strip is clamped between the buckling groove and the limiting frame.

The connecting plug passes through the reserved opening on the surface of the aluminum alloy cable tray and the bend frame, so as to realize the connection and fixation of the aluminum alloy cable tray and the bend frame. The operation is simple and convenient and can be operated with one hand. Attached Figure Description
