Description

Technical Field

[0001] This utility model relates to a cable tray with a fixed structure. Background Technology

[0002] Cable trays, as commonly used wiring support devices in electrical engineering, typically require fixed installation on walls, ceilings, or support frames. Existing cable tray fixing methods mostly rely on bolts or welding, resulting in simple structures, limited adjustment range, cumbersome installation processes, and often poor adaptability and insecure fixing in different sized trays or complex construction environments. Furthermore, some cable tray fixing components lack cushioning and anti-slip designs, easily leading to loosening or even damage of the cable trays during long-term use. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a cable tray with a fixed structure.

[0004] A cable tray with a fixed structure includes a trough-shaped body and a mounting base for fixing the tray to a supporting structure. The mounting base includes a horizontal base plate and at least one pair of snap-fit ​​plates vertically mounted on the base plate. The horizontal base plate has a slide rail perpendicular to the side wall of the trough-shaped body. The pair of snap-fit ​​plates are connected to the slide rail by a slider and can slide along the slide rail to adjust the width between the snap-fit ​​plates. A limiting device is provided between the slider and the slide rail. The upper part of the pair of snap-fit ​​plates is provided with symmetrical locking devices. The locking devices include positioning holes provided on the snap-fit ​​plates, with positioning pins provided in the positioning holes. One end of the positioning pin passes through the positioning hole and presses against the side wall of the trough-shaped body. The other end of the positioning pin is provided with a spring seat, and a tension spring is provided between the spring seat and the snap-fit ​​plate. The mounting base is also provided with a set of symmetrical lifting lugs, which are connected to the mounting rod by lifting rings.

[0005] As a further improvement, the slider is a T-shaped slider, and the limiting device includes threaded holes on both sides of the T-shaped slider and limiting screws set in the threaded holes. The T-shaped slider, in conjunction with the limiting screws, slides more stably, is installed more firmly, and avoids accidental derailment.

[0006] As a further improvement, the locking device includes a positioning hole on the snap-fit ​​plate, a nut on the outside of the positioning hole, the nut being welded to the snap-fit ​​plate, and a claw screw inside the nut. Tightening the claw screw can drive the end of the claw screw to press against the side wall of the groove-shaped body. The claw screw is easy to operate and can be tightened by hand without additional tools, facilitating quick on-site installation.

[0007] As a further improvement, the lifting lug and the mounting base are connected by thread or welding, providing both threaded connection and welding methods to meet different construction conditions and improve applicability.

[0008] As a further improvement, the end of the positioning pin or jack screw is provided with a rubber pad. The rubber pad has a buffering effect, avoids damage to the surface of the cable tray, and enhances the anti-slip fixing effect.

[0009] As a further improvement, the surface of the rubber pad is provided with textures or teeth to increase friction, thereby further increasing friction and maintaining stability under vibration or load changes.

[0010] Beneficial effects: Adjustable width: The snap-fit ​​plate is connected to the slide rail via a slider and can slide to adapt to different sizes of cable trays.

[0011] Reliable limiting: The limiting device can prevent the slider from falling off or shifting, ensuring stability.

[0012] Double locking: The slotted body is pressed tightly by locating pins or jack screws, ensuring reliable fixation and preventing loosening.

[0013] Quick installation: The sliding, snap-fit, and lifting lug connections reduce on-site welding or drilling processes.

[0014] Good protection: Rubber pads at the ends of locating pins or jack screws prevent damage to the cable tray surface and enhance friction.

[0015] Highly adaptable: The lifting lugs can be either threaded or welded, making them suitable for various installation environments.

[0016] High safety: The texture or teeth on the surface of the rubber pad further enhance friction and improve fixation stability. Attached Figure Description
