[0022] Referring to "embodiment" herein means that a specific feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appearing in various positions in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0023] An embodiment of the present utility model provides a horizontal bridge for cable laying, as Figures 1-5As shown in the figure, the horizontal cable tray for cable laying includes: a housing 1 for protecting the cable; a limiting plate 2 fixed inside the housing 1; a baffle 3 slidably installed inside the housing 1 for closing the housing 1, the baffle 3 being in sliding contact with the limiting plate 2; a dust-proof net 4 provided on the baffle 3 for isolating dust; a threaded hole 5 provided on the housing 1, and a fixing bolt threadedly connected to the baffle 3 is threadedly installed in the threaded hole 5; and a support assembly installed on the housing 1 and the baffle 3 for supporting the cable.

[0024] In this embodiment, the housing 1 serves as the main protective shell for the cable, preventing the cable from directly contacting the external environment and reducing the risk of damage. By providing a relatively enclosed environment, it effectively reduces the damage to the cable caused by external factors. The limiting plate 2 ensures the stability and accuracy of the baffle 3 during the sliding process. The design of the baffle 3 makes the installation and maintenance of the cable more convenient. At the same time, it can close the housing 1 when not in use, improving the protection of the cable. The dust-proof net 4 is used to isolate dust and sundries, preventing them from entering the inside of the housing 1 and causing damage to the cable. At the same time, it can increase the heat dissipation effect of the device. By using the threaded hole 5 and the fixing bolt in cooperation, the position of the baffle 3 can be firmly fixed to ensure its stability when it does not need to be moved. The support assembly is used to support the cable, preventing the cable from sagging or moving in the cable tray and ensuring the stability and safety of the cable.

[0025] In a further preferred embodiment of the present invention, the support assembly includes a plurality of mounting plates 6 fixed on one side of the baffle 3 close to the limiting plate 2; limiting wheels 7 respectively rotatably installed on the housing 1 and the plurality of mounting plates 6, the plurality of limiting wheels 7 can be in contact with each other in pairs, and inner grooves are provided on the plurality of limiting wheels 7; and an insulating pad 8 fixedly sleeved outside the plurality of limiting wheels 7.

[0026] In this embodiment, the mounting plate 6 serves as the installation base for the limiting wheel 7, ensuring the stability and correct installation position of the limiting wheel 7. The plurality of limiting wheels 7 can be in contact with each other in pairs to form a continuous support surface for supporting the cable. The inner groove is used to accommodate the cable, preventing the cable from sliding or moving in the cable tray. The rotational design of the limiting wheel 7 allows the cable to move more smoothly, reducing the direct friction between the cable and the cable tray. At the same time, the design of the inner groove provides a fixed position for the cable, preventing the cable from shaking and sagging, improving the safety of the cable. The insulating pad 8 is used to isolate the direct contact between the cable and the limiting wheel 7, preventing the cable tray from being electrified due to the cable contacting the metal limiting wheel 7 after the cable is damaged, greatly increasing the safety of the cable. Even if the cable is damaged, due to the isolation of the insulating pad 8, it can effectively prevent the cable tray from being electrified and reduce the safety risk.

[0027] In a further preferred embodiment of the present utility model, a plurality of clamping plates 11 are installed on one side of the housing 1, and a connecting plate 12 for connecting the two housings 1 is slidably installed between the plurality of clamping plates 11. Two limiting members for clamping the connecting plate 12 are installed on one side of the housing 1, and the two limiting members can respectively contact the two connecting plates 12.

[0028] In this embodiment, the clamping plates 11 are used to provide a sliding track for the connecting plate 12 to ensure that the connecting plate 12 can slide stably and smoothly. The connecting plate 12 is used to connect two adjacent housings 1. By connecting a plurality of housings 1, the length or shape of the bridge is extended to adapt to different cable layout requirements. The limiting members are used to clamp the connecting plate 12 to ensure that the connecting plate 12 can remain stable after sliding to an appropriate position and prevent it from sliding or falling off accidentally.

[0029] In a further preferred embodiment of the present utility model, the limiting member is composed of a rotating shaft 13, a fixing plate 14, a spring 15 and a clamping block 16. The rotating shaft 13 is fixed on the housing 1, the fixing plate 14 is rotatably installed on the rotating shaft 13, the spring 15 is fixed on the fixing plate 14, the clamping block 16 is fixed on the spring 15, and two clamping openings are provided on each of the two connecting plates 12. The clamping block 16 can extend into any one of the clamping openings.

[0030] In this embodiment, the rotating shaft 13 serves as the rotation center of the fixing plate 14, and the fixing plate 14 serves as the support structure for the spring 15 and the clamping block 16, increasing the flexibility of the clamping block 16. The spring 15 provides elastic force for the clamping block 16 to ensure that the clamping block 16 can automatically pop out and snap into the clamping opening. The clamping block 16 is the core component of the connecting part, and its shape and size match the clamping opening on the connecting plate 12. When the clamping block 16 is popped out by the spring 15, it can snap into the clamping opening to fix the connecting plate 12 and the housing 1.

[0031] In a further preferred embodiment of the present utility model, a limiting telescopic rod 17 is provided in each of the two springs 15. The limiting telescopic rod 17 is composed of an outer cylinder and an inner cylinder. The outer cylinder is fixed on the fixing plate 14, the inner cylinder is fixed on the clamping block 16, and the outer cylinder is movably sleeved outside the inner cylinder.

[0032] In this embodiment, through the design of the limiting telescopic rod 17, when the block 16 is extended and retracted under the elastic force of the spring 15, the inner cylinder performs a stable telescopic movement inside the outer cylinder, which effectively prevents the block 16 from deflecting or shaking, thereby improving the stability of the connecting piece during use. The limiting telescopic rod 17 provides additional support and guidance for the extension and retraction of the block 16, ensuring that the block 16 can accurately snap into or out of the snap-in on the connecting plate 12. This design reduces the risk of connection failure due to improper operation or external interference, and enhances the reliability of the bridge structure. Due to the presence of the limiting telescopic rod 17, the lateral force exerted on the spring 15 during the extension and retraction process is effectively dispersed and alleviated, reducing the risk of fatigue and damage to the spring 15.

[0033] In a further preferred embodiment of the present invention, a connecting rope 18 is fixed to the clamping block 16 , the connecting rope 18 passes through the limiting telescopic rod 17 and extends to the top of the fixing plate 14 , and a pull ring 19 is installed on the connecting rope 18 .

[0034] In this embodiment, a method for directly operating the card block 16 from the outside is provided, so that the user can operate the card block 16 without directly touching or approaching the card block 16. The pull ring 19 serves as the operating end of the connecting rope 18, and the user can easily control the extension and retraction of the card block 16 by pulling the pull ring 19.

[0035] In a further preferred embodiment of the utility model, a movable sleeve is provided on the shell 1 with a clamping ring 9, and a support plate 10 is installed on the clamping ring 9. The support plate 10 can be fixed to the building surface by bolts. An opening is provided at the bottom of the shell 1, and the baffle 3 covers the opening.

[0036] In this embodiment, the clamping ring 9 can slide or rotate along the outer wall of the shell 1 to adapt to different installation requirements. The support plate 10 serves as a connecting bridge between the shell 1 and the building surface to ensure that the horizontal cable bridge can be stably installed on the building. The coordinated use of the clamping ring 9 and the support plate 10 can ensure that the horizontal cable bridge is stably installed on the building surface. The support plate 10 is fixedly connected to the building surface by fasteners such as bolts, providing strong supporting force to prevent the bridge from shaking or falling off due to external force.

[0037] In a further preferred embodiment of the utility model, an anti-slip pad is fixed on the inner wall of the retaining ring 9, and the anti-slip pad can contact the outer wall of the shell 1. A limiting bolt that can be connected to the shell 1 is installed on the retaining ring 9, and the shell 1 and the baffle 3 are both provided with an anti-corrosion coating.

[0038] In this embodiment, the anti-slip pad increases the friction between the snap ring 9 and the housing 1, thereby preventing the housing 1 from sliding or rotating within the snap ring 9, improving the firmness of the installation. The limit bolt can further fix the positions of the snap ring 9 and the housing 1, preventing loosening or detachment caused by external forces, ensuring the stability and safety of the cable tray. The anti-corrosion coating can effectively prevent material damage caused by environmental factors (such as moisture, corrosion, etc.), extending the service life of the cable tray.

[0039] In summary, compared with the related technologies, the device of the present application forms a storage space for cables by the cooperation of the housing 1 and the baffle 3, which can protect the cables. By setting the limit wheels 7 and the insulating pads 8, the cables can be supported, reducing the friction between the cables and the inner wall of the device during cable laying, preventing the abrasion of the cable epidermis, and at the same time preventing the device from being energized as a whole when the cable is damaged and directly contacting the device, increasing the safety and protection effect of the device. By setting the connecting plate 12 and the limiting member, different numbers of housings 1 can be connected together, increasing the flexibility of the device.
