New specifications of cable trays need to be customized, resulting in waste and delays in the construction period. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a retractable and adjustable cable tray. This solves the problem that existing cable trays are usually fixed structures. When construction projects require changes due to unreasonable settings, such as the need for a wider cable tray, the fixed cable tray specifications are not suitable and cannot continue to be used. This necessitates the customization of new specifications of cable trays, resulting in waste and delays in the construction cycle.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A retractable and adjustable cable tray includes a first side plate, a first support plate on one bottom side of the first side plate, first limiting plates rotatably mounted on both ends of the first support plate, a plurality of evenly distributed connecting plates on the first support plate between the two first limiting plates, a support plate with one end connected to the first support plate below the connecting plates, a second side plate on the opposite side of the first side plate, a second support plate on one bottom side of the second side plate, second limiting plates rotatably mounted on both ends of the second support plate and connected to the first limiting plates, a fixing rod detachably mounted between the second limiting plates and the first limiting plates, and a guide plate corresponding to each connecting plate on the second support plate between the two second limiting plates.

[0007] As a further embodiment of this utility model, both the first limiting plate and the second limiting plate are provided with multiple fixing holes, and the two ends of the fixing rod are provided with screws that can pass through the fixing holes and be fixed by screwing nuts.

[0008] As a further embodiment of this utility model, the end of the guide plate away from the second support plate is provided with two opposing baffles, and a travel groove for the connecting plate to be inserted is formed between the two baffles.

[0009] As a further embodiment of this utility model, a reinforcing block is provided on the inner end face of the baffle, and a moving groove for the reinforcing block to move is provided on both sides of the connecting plate.

[0010] As a further embodiment of this utility model, a guide block is provided on the bottom end face of the baffle, and a guide groove for displacement of the guide block is provided on the top end face of the support plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] When the width of the cable tray needs to be adjusted, the operator can adjust the included angle between the first and second limiting plates according to the required width of the cable tray. Then, a fixing rod is used to limit and fix the included angle between the first and second limiting plates, thereby limiting and fixing the cable tray after the width is adjusted, preventing changes in the width of the cable tray, and ensuring the stability of the cable tray in use. This utility model is simple and convenient to operate, can flexibly adjust the width of the cable tray, has good environmental adaptability, and improves the error tolerance of design and construction, avoiding waste and construction delays.

[0019] Example

[0020] refer to Figures 1-3 A retractable and adjustable cable tray includes a first side plate 1. A first support plate 11 is fixedly connected to one side of the bottom of the first side plate 1. A first limiting plate 12 is rotatably provided at both ends of the first support plate 11. A plurality of evenly distributed connecting plates 13 are fixedly connected to the first support plate 11 between the two first limiting plates 12. A support plate 131 with one end fixedly connected to the first support plate 11 is provided below the connecting plate 13. A second side plate 2 is provided on the opposite side of the first side plate 1. A second support plate 21 is fixedly connected to one side of the bottom of the second side plate 2. A second limiting plate 22 is rotatably provided at both ends of the second support plate 21 and hinged to the first limiting plate 12. A fixing rod 14 is detachably provided between the second limiting plate 22 and the first limiting plate 12. A guide plate 23 corresponding to the connecting plate 13 is fixedly connected to the second support plate 21 between the two second limiting plates 22.

[0021] Furthermore, the guide plate 23 is provided with two opposing baffles 231 at one end away from the second support plate 21, and a travel groove 232 for the connecting plate 13 to be inserted is formed between the two baffles 231.

[0022] Furthermore, a reinforcing block 233 is provided on the inner end face of the baffle 231, and a moving groove 132 for the reinforcing block 233 to move is provided on both sides of the connecting plate 13. The connection strength between the first support plate 11 and the second support plate 21 is strengthened by the setting of the moving groove 132 and the reinforcing block 233.

[0023] Furthermore, a guide block 234 is provided on the bottom end face of the baffle 231, and a guide groove 133 for the guide block 234 to move is provided on the top end face of the support plate 131. Through the setting of the guide groove 133 and the guide block 234, the connection strength between the first support plate 11 and the second support plate 21 is further strengthened, and the load-bearing capacity of the cable tray is improved.

[0024] Furthermore, both the first limiting plate 12 and the second limiting plate 22 are provided with multiple fixing holes 121. The fixing rod 14 has screws 141 at both ends that can pass through the fixing holes 121 and be screwed in by nuts 142. By aligning the screws 141 at both ends of the fixing rod 14 with the fixing holes 121 on the first limiting plate 12 and the second limiting plate 22 respectively, and then screwing them in by nuts 142, the fixing rod 14 is fixedly connected to the first limiting plate 12 and the second limiting plate 22 and will not fall off. The fixing rod 14 can limit and fix the included angle between the first limiting plate 12 and the second limiting plate 22, thereby limiting and fixing the cable tray after the width is adjusted, avoiding changes in the width of the cable tray, and ensuring the stability of the cable tray in use.

[0025] The working principle of this utility model:

[0026] When the cable tray width needs to be adjusted, the operator loosens the nut 142 and removes the fixing rod 14. Then, according to the required cable tray width, the operator pulls the first side plate 1 or the second side plate 2 to adjust the angle between the first limiting plate 12 and the second limiting plate 22. At the same time, the connecting plate 13 moves in the travel groove 232, the reinforcing block 233 moves synchronously in the moving groove 132, and the guide block 234 also moves synchronously in the guide groove 133. Then, the screws 141 at both ends of the fixing rod 14 are aligned with the fixing holes 121 on the first limiting plate 12 and the second limiting plate 22 respectively and inserted. Finally, the nut 142 is screwed onto the screws 141 to fix the fixing rod 14 to the first limiting plate 12 and the second limiting plate 22. The fixing rod 14 can limit and fix the angle between the first limiting plate 12 and the second limiting plate 22, thereby limiting and fixing the cable tray after the width is adjusted, preventing changes in the cable tray width, and ensuring the stability of the cable tray.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
