Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, specifically to a cable tray that facilitates the fixing of wires. Background Technology

[0002] Cable trays are classified into various structures such as 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 (structure) supports and pipe rack supports. They should be characterized by simple structure, beautiful appearance, flexible configuration, and convenient maintenance. All parts must be galvanized. Cable trays installed outdoors are also permitted.

[0003] Chinese Patent Publication No. CN216489521U discloses a cable tray, including an upper reinforcing plate, a lower reinforcing plate, and symmetrical connecting plates and side plates on both sides of the upper and lower reinforcing plates. A hook seat is provided on the upper right side of the side plate, and a fastening plate is provided on the left side of the connecting plate. The fastening plate engages with the hook seat. A first reinforcing seat is provided on the right side of the connecting plate, and the upper reinforcing plate is secured within two of the first reinforcing seats. A second reinforcing seat is provided on the lower right side of the side plate, and the lower reinforcing plate is secured within two of the second reinforcing seats. The middle part of the side plate is a double-walled hollow plate. This utility model increases the heat dissipation performance of the cable tray and enhances its strength through the double-walled hollow plate on the side. The two rectangular cavities also increase heat dissipation performance, and both the upper and lower reinforcing plates effectively strengthen the cable tray.

[0004] However, the aforementioned Xi'an technology does not allow for convenient fixing of the conductors to the cable tray during use. The conductors are prone to moving on the cable tray under stress, which can cause wear and tear. Therefore, there is an urgent need for a cable tray that facilitates the fixing of conductors. Utility Model Content

[0005] The purpose of this invention is to provide a cable tray that facilitates the fixing of wires, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a cable tray for easy fixing of wires, comprising a cable tray and an end cap provided on the cable tray;

[0007] The cable tray has a lower arc-shaped seat fixedly connected to its inner bottom. A pressure plate is installed inside the cable tray, and an upper arc-shaped seat is fixedly connected to the bottom of the pressure plate. Two crossbars are fixedly connected to the bottom of the cable tray. Slide grooves are respectively opened on the opposite sides of the two crossbars. A bidirectional lead screw is rotatably installed in each slide groove. The front of each bidirectional lead screw movably passes through the crossbar and extends to its outside. A handle is fixedly connected to the front of each bidirectional lead screw. A slider is threaded onto the surface of the bidirectional lead screw's positive and negative threads. A positioning frame is fixedly connected to the end of each slider away from the slide groove. Two sliding holes are opened at the bottom of the cable tray. A pull rod is slidably inserted into each of the two sliding holes. A positioning block is fixedly connected to the bottom of each pull rod. A first spring is sleeved on the surface of each pull rod.

[0008] Preferably, the top of the pull rod is fixedly connected to the pressure plate, and the pressure plate is slidably disposed inside the cable tray.

[0009] When fixing the cables in the cable tray, the cables are laid in the lower arc-shaped seat. By pulling down the positioning block, the pull rod drives the pressure plate to move downward. The pressure plate squeezes the first spring, the first spring contracts, and the upper arc-shaped seat moves downward and abuts against the cables in the lower arc-shaped seat.

[0010] Preferably, the sliders are slidably disposed in the grooves, and the first spring is located between the pressure plate and the bottom wall of the cable tray.

[0011] Preferably, the cable tray has heat dissipation vents at both the front and rear ends, and two mounting brackets are fixedly connected to the bottom of the cable tray. The top and front and rear ends of the two mounting brackets are respectively provided with through holes, and threaded rods are inserted into the through holes.

[0012] Then, turn the lever to rotate the bidirectional lead screw, which in turn moves the slider inward and the positioning frame inward. The positioning frame then moves above the positioning block, thus fixing the positioning block and securing the cable.

[0013] Preferably, nuts are threadedly connected to the bottom surface of each threaded rod, and a mounting plate is fixedly connected to the top of each pair of threaded rods, with mounting holes opened on the top of each mounting plate.

[0014] Preferably, the cable tray has telescopic holes at both the front and rear ends, and a second spring is fixedly connected to each telescopic hole. A telescopic buckle is fixedly connected to the end of the second spring away from the cable tray, and the telescopic buckle is slidably disposed in the telescopic hole.

[0015] The included ventilation openings facilitate airflow inside the cable tray, while the mounting brackets, equipped with threaded rods and nuts for securing the cable tray, along with the mounting plate, make it easy to install the cable tray into the designated position.

[0016] Preferably, the end cap has limit holes at both the front and rear ends, and the limit holes are adapted to the telescopic buckle.

[0017] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0018] First, in this utility model, when fixing cables in a cable tray, the cables are laid in the lower arc-shaped seat. By pulling down the positioning block, the pull rod drives the pressure plate to move downward. The pressure plate squeezes the first spring, and the first spring contracts, causing the upper arc-shaped seat to move downward and abut against the cables in the lower arc-shaped seat. Then, by turning the handle, the bidirectional lead screw rotates, which in turn causes the slider to move inward at the same time, and the positioning frame to move inward at the same time. The positioning frame moves to above the positioning block, thereby fixing the positioning block and fixing the cables, which is convenient and easy.

[0019] Secondly, this utility model facilitates air circulation inside the cable tray by setting heat dissipation vents. The mounting bracket has threaded rods and nuts for fixing, which, together with the mounting top plate, makes it easy to install the cable tray into the predetermined position. The cable tray has telescopic holes at both ends, and a second spring and telescopic buckle are installed in the telescopic holes. The end cap has corresponding limiting holes at the front and rear ends, so that the end cap can be firmly fixed on the cable tray. Attached Figure Description
