Description

Technical Field

[0001] The present invention belongs to the technical field of cable trays, and particularly relates to a buckle lock for a cable tray and a cable tray. Background Art

[0002] Cable trays are divided into trough type, tray type, ladder type, grid type and other structures, and are composed of brackets, brackets and installation accessories, etc. The cable trays in buildings can be erected independently or attached to various building and pipe gallery brackets. They should reflect the characteristics of simple structure, beautiful appearance, flexible configuration and convenient maintenance. All parts need to be galvanized. The cable trays installed outdoors in buildings.

[0003] During the fixing process of the cable tray, screws and bolts are usually used to fix the cover plate and the cable tray. It is often necessary to disassemble the screws and bolts, and usually a variety of disassembly tools are required, which is rather inconvenient. And frequent disassembly will also cause wear and tear on the screws and bolts. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the purpose of the present invention is to provide a buckle lock for a cable tray and a cable tray.

[0005] The purpose of the present invention can be realized by the following technical solutions:

[0006] A buckle lock for a cable tray and a cable tray include a cable tray, a cover plate and a plurality of ladder plate fixing mechanisms.

The cover plate includes a plate body, and a second retaining piece is provided at the bottom end of the plate body. A bracket and a sliding rod are fixedly provided on the plate body. A cylindrical rod slides on the bracket. A first retaining piece is also fixedly provided on the cylindrical rod. A first spring is sleeved on the cylindrical rod. Two connecting rods are rotatably connected to the bottom end of the cylindrical rod. The upper ends of the two connecting rods are rotatably connected to a moving plate. Both moving plates are slidably connected to the sliding rod. A buckle is fixedly provided on the first retaining piece. A slot is also provided on the bracket on one side of the buckle.

[0007] The ladder plate fixing mechanism includes a ladder plate. A limit disk is fixedly provided on one of the ladder plates. A rotating rod is rotatably provided in the limit disk. The rotating rod is rotatably connected to the bottom end of the ladder plate. Two first rotating rods are fixedly connected to the bottom end of the rotating rod.

[0028] The bridge 1 includes a bridge plate 101. A number of ventilation holes 102 and limiting grooves 103 are also provided on the bridge plate 101.

[0029] The ladder plate fixing mechanism 3 includes a number of ladder plates 301. A limit disk 311 is fixedly arranged on one of the ladder plates 301. A rotating rod 309 is rotatably arranged in the limit disk 311. A groove 313 is further arranged at the top end of the rotating rod 309. A first telescopic rod 314 is fixedly arranged in the groove 313. The top end of the first telescopic rod 314 is fixedly connected with a limit rod 310. A number of limit holes 312 are arranged in a circumferential array on the limit disk 311. The bottom end of the rotating rod 309 is fixedly connected with a rotating seat 306. The rotating seat 306 is rotatably connected with the bottom end of the ladder plate 301. Two first rotating rods 307 are fixedly connected to the rotating seat 306. A second rotating rod 308 is rotatably connected to each of the two first rotating rods 307. A first slider 302 is rotatably connected to each of the two second rotating rods 308. A second spring 303 is fixedly connected to each of the two first sliders 302. The other ends of the two second springs 303 are fixedly connected with the ladder plate 301. The two first sliders 302 both slide on the ladder plate 301. A second telescopic rod 304 is fixedly connected to each of the two first sliders 302. A first fixing frame 305 is fixedly connected to each of the two second telescopic rods 304. The two first fixing frames 305 are respectively located on both sides of the ladder plate 301.

[0030] Two second sliders 316 are arranged on each of the remaining ladder plates 301. A third telescopic rod 317 is further arranged on each of the two second sliders 316. A second fixing frame 318 is fixedly arranged on each of the two third telescopic rods 317. The two second fixing frames 318 are respectively located on both sides of the ladder plate 301. The second sliders 316 on a number of the ladder plates 301 are all fixedly connected with the first slider 302 through a connecting rod 315.

[0031] During use, place the cable on the ladder board 301 of the cable tray 1. Move the limit rod 310 upward in cooperation with the first telescopic rod 314 so that a part of the rod body of the limit rod 310 remains in the groove 313 for rotating the rotating rod 309. While the rotating rod 309 rotates, the rotating seat 306 fixedly connected to its bottom end also rotates accordingly. While the rotating seat 306 rotates, it drives the first rotating rod 307 and the second rotating rod 308 to rotate, realizing the movement of the two first sliders 302 on the ladder board 301, and the moving directions of the two first sliders 302 are opposite. Through the cooperation of the second spring 303 and the two first sliders 302, the distance between the two first sliders 302 can be adjusted. After the distance is adjusted, move the limit rod 310 downward so that both ends of the limit rod 310 are fixed in the limit holes 312 to fix the positions of the two first sliders 302, and limit the cable according to the number and arrangement width of the cables at both ends. Subsequently, control the second telescopic rod 304 to shorten downward so that the first fixing bracket 305 moves downward to fix the cable from both sides of the ladder board 301, which can be applicable to the fixation of cables with different diameters, and the synchronous movement of the first slider 302 and the second slider 316 can be realized through the connecting rod 315.

[0032] After the cable is fixed on the ladder board 301, cover the cover plate 2. Push the push rod 205 on the cover plate 2, and the cylindrical rod 206 fixedly connected to the push rod 205 moves downward accordingly. During the downward movement of the cylindrical rod 206, the moving plates 215 on the two connecting rods 212 slide on the sliding rod 214 towards both ends thereof until the limiting plate 216 moves into the limiting groove 103. The buckle 208 on the cylindrical rod 206 also moves downward accordingly. When the convex block on the buckle 208 reaches the notch 203 on the bracket 202, it will be stuck, and the cover plate 2 is clamped with the cable tray 1.

[0033] By gently pressing the pressing plate 204, the buckle 208 can be disengaged from the notch 203 on the bracket 202, the first spring 209 extends, the cylindrical rod 206 moves upward, driving the limiting plate 216 to move from both ends to the middle, separating the cover plate 2 from the cable tray 1.
