[0022] Please see Figure 1-5 The present invention provides a technical solution as follows:

[0023] Example 1:

[0024] A cable tray with an anti-cable-crossing structure includes a tray body 100, a cover plate 200 on the tray body 100, and the cover plate 200 is installed on the tray body 100 by a snap-fit ​​assembly. Multiple sets of limiting components to prevent cable crossing are provided inside the tray body 100. Each set of limiting components includes a first mounting block 300 and a second mounting block 301 located at the bottom of the inner wall of the tray body 100. The first mounting block 300 and the second mounting block 301 are installed at the bottom of the inner wall of the tray body 100 by a sliding assembly. A mounting frame 302 is fixedly provided on the first mounting block 300, and a rotating plate 303 is fixedly provided on the second mounting block 301. The rotating plate 303 is rotatably disposed within the mounting frame 302. Clamping plates 304 are provided at the ends of both the mounting frame 302 and the rotating plate 303. A pressing assembly is provided on the cover plate 200 to drive the two clamping plates 304 to move relative to each other. A reset component is provided between the first mounting block 300 and the second mounting block 301.

[0025] The snap-fit ​​assembly includes multiple slots 101 formed on the cable tray body 100, and the cover plate 200 is provided with multiple snap blocks 201 that cooperate with the slots 101.

[0026] The slot 101 and the block 201 have L-shaped cross sections.

[0027] The sliding assembly includes a slider 307 located at the bottom of the first mounting block 300 and the second mounting block 301, and a groove 308 that cooperates with the slider 307 is provided at the bottom of the inner wall of the bridge body 100.

[0028] The pressing assembly is provided in multiple sets, and each set of the pressing assembly includes a connecting rod 202 installed at the bottom end of the cover plate 200, and the end of the connecting rod 202 is provided with a pressing block 203.

[0029] The extrusion block 203 has a trapezoidal cross section, and the surfaces of the first mounting block 300 and the second mounting block 301 that contact the extrusion block 203 are inclined surfaces.

[0030] The reset component includes a spring 306 fixedly mounted on the first mounting block 300, and the end of the spring 306 away from the first mounting block 300 is connected to the second mounting block 301.

[0031] The inner wall of the clamping plate 304 is provided with a protective pad 305, and the protective pad 305 is made of rubber.

[0032] Working Principle: During use, cables located in the cable tray body 100 may move due to accidental contact or vibration, potentially causing wear or damage to their insulation layer, affecting the cable's service life and performance. By placing the cable between opposing clamps 304 and placing the cover plate 200 on the cable tray body 100, the pressing block 203 installed at the end of the connecting rod 202 is inserted between different sets of first mounting blocks 300 and second mounting blocks 301. Since the pressing block 203 is trapezoidal in shape, and the contact surface between the first mounting block 300 and second mounting block 301 and the pressing block 203 is inclined, the pressing block 203 presses the gap between the first mounting block 300 and second mounting block 301 as it moves downward. Since the first mounting block 300 and second mounting block 301 are slidably disposed at the bottom of the inner wall of the cable tray body 100 via slider 307 and groove 308, the pressing block 203 pushes the different sets of first mounting blocks 300 and second mounting blocks while pressing. 301 performs opposing movements. Since the rotating plate 303 is rotatably set inside the mounting frame 302, while the first mounting block 300 and the second mounting block 301 slide, the rotating plate 303 is driven to rotate within the mounting frame 302, thereby causing the two clamping plates 304 to move relative to each other to fix the cable, thereby achieving the purpose of preventing errors and reducing the risk of short circuit accidents. The protective pad 305 can protect the cable and absorb and disperse the force generated by vibration or impact, reducing cable damage. While the cover plate 200 moves downward, the locking block 201 located at the end of the cover plate 200 is inserted into the locking slot 101. Since the locking block 201 and the locking slot 101 are L-shaped, after the locking block 201 is inserted into the locking slot 101, the cover plate 200 only needs to be pushed lightly to complete the fixation. Conversely, by pushing the cover plate 200 in the opposite direction, the cover plate 200 can be removed to complete the separation. The first mounting block 300 and the second mounting block 301 are pushed back to their original positions under the action of the spring 306.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
