Description

Technical Field

[0001] The utility model relates to the technical field of cable bridges, in particular to a protective bridge for laying cables. Background Art

[0002] Cable tray is a device used to support and protect cables. It is usually installed on the ceiling or wall of a building or other structure with the help of an external bracket. It is one of the commonly used equipment in the cable laying process. Cable tray is usually made of metal or plastic.

[0003] A patent document with publication number CN214176744U has appeared in the prior art, which discloses a trough-type cable bridge, including a bridge frame 1 and a bridge frame 2, wherein a U-shaped card plate is arranged on the top of the bridge frame 1, and card slots are opened on the top of the front and back of the bridge frame 1 and the bridge frame 2, and a through slot is arranged on the front and back of the bridge frame 1. Before use, when the bridge frame needs to be disassembled, the moving block is first pressed, and the moving block drives the telescopic rod and the compression spring to move. The telescopic tension of the telescopic rod and the compression spring drives the moving block to move to the inner cavity of the positioning groove 1, and then the user pulls the bridge frame 2, and the bridge frame 2 drives the positioning block 1 to move out of the inner cavity of the positioning groove 1. The above steps complete the disassembly of the bridge frame 1 and the bridge frame 2. During installation, the above steps can be performed in reverse order. The operation is simple and convenient. By setting a protective pad, the phenomenon of direct collision between the positioning block 1 and the inner wall of the positioning groove 1 is avoided, and the positioning block 1 and the positioning groove are protected together.

[0004] The above and existing technologies have the following defects: after laying multiple cables in the cable tray, the cables are easily entangled with each other and become messy, which makes it inconvenient to distinguish the information of the cables later, thereby reducing the practicality of the cable tray.

[0005] Therefore, a protective bridge for cable laying is proposed. Utility Model Content

[0006] The utility model aims to solve the shortcomings that cables are easily entangled with each other and become messy, making it inconvenient to distinguish the information of the cables later, and proposes a protective bridge frame for laying cables.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a protective bridge for cable laying, comprising a wiring frame, a cover plate is detachably installed on the surface of the wiring frame, an operation port is opened on the surface of the cover plate, and a plurality of limiting structures are provided on the inner wall of the wiring frame, and the limiting structure comprises a fixed tube, the fixed tube is fixedly connected to the wiring frame, an adjustment plate is slidably connected to the inner wall of the fixed tube, a splint is slidably connected inside the adjustment plate, a square plate is fixedly connected to the surface of the splint, and a spring is fixedly connected between the square plate and the adjustment plate.

[0008] The effect achieved by the above components is: by setting a limiting structure, when laying cables, the position of the cables can be limited with the help of the clamping plate and the adjustment plate, thereby preventing the cables from being entangled with each other and becoming messy, making it easier to distinguish the cable information later, thereby improving the practicality of the cable tray.

[0009] Preferably, a bolt is threadedly connected to the fixing tube, and the bolt passes through the fixing tube and abuts against the surface of the adjusting plate.

[0010] The effect achieved by the above components is that when the bolts abut against the surface of the adjusting plate, the bolts achieve the function of limiting the position of the adjusting plate.

[0011] Preferably, a baffle is fixedly connected to the fixing tube relative to the bolt, and the vertical cross-section of the baffle is "L"-shaped.

[0012] The effect achieved by the above components is that after the bolt contacts the baffle, the baffle limits the moving distance of the bolt and prevents the bolt from being out of contact with the fixing pipe.

[0013] Preferably, a rectangular hole is opened on the surface of the fixing tube, an extension plate is fixedly connected to the surface of the adjusting plate, and the extension plate is located in the rectangular hole.

[0014] The effect achieved by the above components is that during the adjustment process, the adjustment plate drives the extension plate to move along the rectangular hole, and the rectangular hole reaches a position to limit the extension plate, thereby preventing the adjustment plate from escaping from the inner wall of the fixed tube.

[0015] Preferably, a shielding structure is provided on the surface of the cover plate, and the shielding structure includes two U-shaped plates, the U-shaped plate is fixedly connected to the cover plate, the inner wall of the U-shaped plate is slidably connected with a slide plate, the slide plate is slidably connected to the cover plate, the surface of the slide plate is rotatably connected with a rotating plate, the size of the rotating plate is larger than the size of the operating port, the surface of the rotating plate is fixedly connected with a clamping plate, the surface of the cover plate is fixedly connected with a positioning frame, the clamping plate is slidably connected to the positioning frame, and the rotating plate is slidably connected to the cover plate.

[0016] The effect achieved by the above components is: by setting a shielding structure, after the cable is limited, the operating port is shielded by the rotating plate to prevent foreign objects from entering the wiring frame and causing damage to the cable, thereby ensuring that the wiring frame and the cover plate can normally protect the cable.

[0017] Preferably, a magnetic sheet is fixedly connected to the surface of the card plate, and the positioning frame is an iron frame.

[0018] The effect achieved by the above components is that the movement of the card plate will cause the magnetic sheet to contact the positioning frame. At this time, the magnetic sheet will be attracted to the surface of the positioning frame by its own magnetic force, thereby limiting the position of the card plate.

[0019] Preferably, a plurality of anti-slip strips are fixedly connected to the surface of the rotating plate.

[0020] The effect achieved by the above components is that the anti-slip strip can increase the friction force on the surface of the rotating plate, thereby facilitating the sliding of the rotating plate.

[0021] Compared with the prior art, the advantages and positive effects of the utility model are:

[0022] 1. In the utility model, by setting a limit structure, when laying cables, the position of the cables can be limited by the cooperation of the clamping plate and the adjusting plate, thereby preventing the cables from being entangled with each other and causing a mess, making it convenient to distinguish the information of the cables later, thereby improving the practicality of the cable tray.

[0023] 2. In the utility model, by setting a shielding structure, after the cable is limited, the operating port is shielded by a rotating plate to prevent foreign matter from entering the wiring frame and causing damage to the cable, thereby ensuring that the wiring frame and the cover plate can normally protect the cable.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0032] like Figure 1-Figure 5 As shown, the utility model provides a protective bridge for cable laying, including a wiring frame 1, a cover plate 2 is detachably installed on the surface of the wiring frame 1, an operation port 3 is opened on the surface of the cover plate 2, a plurality of limiting structures 4 are provided on the inner wall of the wiring frame 1, and a shielding structure 5 is provided on the surface of the cover plate 2.

[0033] The specific configuration and function of the limiting structure 4 and the shielding structure 5 will be described in detail below.

[0034] like Figure 3 and Figure 4 As shown, the limiting structure 4 includes a fixed tube 41, which is fixedly connected to the wiring frame 1, an adjusting plate 42 is slidably connected to the inner wall of the fixed tube 41, a clamping plate 43 is slidably connected inside the adjusting plate 42, a square plate 44 is fixedly connected to the surface of the clamping plate 43, a spring 45 is fixedly connected between the square plate 44 and the adjusting plate 42, a bolt 46 is threadedly connected to the inner wall of the fixed tube 41, the bolt 46 passes through the fixed tube 41 and abuts against the surface of the adjusting plate 42, when the bolt 46 abuts against the surface of the adjusting plate 42, the bolt 46 reaches the function of limiting the position of the adjusting plate 42, and the position of the fixed tube 41 relative to the bolt 46 is fixed A baffle 47 is connected, and the vertical cross-section of the baffle 47 is "L"-shaped. After the bolt 46 contacts the baffle 47, the baffle 47 limits the moving distance of the bolt 46, thereby preventing the bolt 46 from being out of contact with the fixed tube 41. A rectangular hole 48 is provided on the surface of the fixed tube 41, and an extension plate 49 is fixedly connected to the surface of the adjustment plate 42, and the extension plate 49 is located in the rectangular hole 48. During the adjustment process, the adjustment plate 42 will drive the extension plate 49 to move along the rectangular hole 48, and the rectangular hole 48 reaches the position of limiting the extension plate 49, thereby preventing the adjustment plate 42 from escaping from the inner wall of the fixed tube 41.

[0035] like Figure 2 and Figure 5As shown, the shielding structure 5 includes two U-shaped plates 51, the U-shaped plate 51 is fixedly connected to the cover plate 2, the inner wall of the U-shaped plate 51 is slidably connected with a slide plate 52, the slide plate 52 is slidably connected to the cover plate 2, the surface of the slide plate 52 is rotatably connected with a rotating plate 53, the size of the rotating plate 53 is larger than the size of the operating port 3, the surface of the rotating plate 53 is fixedly connected with a clamping plate 54, the surface of the cover plate 2 is fixedly connected with a positioning frame 55, the clamping plate 54 is slidably connected to the positioning frame 55, the rotating plate 53 is slidably connected to the cover plate 2, the surface of the clamping plate 54 is fixedly connected with a magnetic sheet 56, the positioning frame 55 is an iron frame, the movement of the clamping plate 54 will cause the magnetic sheet 56 to contact the positioning frame 55, at this time the magnetic sheet 56 will be attracted to the surface of the positioning frame 55 by its own magnetic force, thereby limiting the position of the clamping plate 54, and the surface of the rotating plate 53 is fixedly connected with a plurality of anti-slip strips 57, the anti-slip strips 57 can increase the friction force on the surface of the rotating plate 53, thereby facilitating the sliding of the rotating plate 53.

[0036] The overall working principle is that when laying the cable, the cable is passed through the wiring frame 1, and then the rotating plate 53 is slid away from the positioning frame 55. At this time, the anti-slip strip 57 can increase the friction on the surface of the rotating plate 53, thereby facilitating the sliding of the rotating plate 53. The sliding of the rotating plate 53 will cause the clamping plate 54 to slide out from the inner wall of the positioning frame 55, and then the rotating plate 53 is rotated so that the rotating plate 53 no longer blocks the operating port 3. After that, the cable is moved through the operating port 3. The movement of the cable will contact and squeeze the clamping plate 43, and the clamping plate 43 will slide along the adjusting plate 42 and drive the square plate 44 to slide. The sliding of the square plate 44 will squeeze the spring 45, so that the spring 45 is in a compressed state, and the cable will continue to slide with The clamping plate 43 is disengaged, and the spring 45 begins to stretch. The square plate 44 will drive the clamping plate 43 to slide with the help of the tension of the spring 45. The sliding of the clamping plate 43 will press the cable against the surface of the adjusting plate 42. The clamping plate 43 and the adjusting plate 42 can cooperate to limit the position of the cable, thereby preventing the cables from being entangled with each other and becoming messy. When the height of the cable needs to be adjusted, the bolt 46 is turned, and the bolt 46 moves away from the adjusting plate 42 with the help of the thread. The bolt 46 moves and is disengaged from the adjusting plate 42. At the same time, the bolt 46 comes into contact with the baffle 47. The baffle 47 reaches the limit of the moving distance of the bolt 46, preventing the bolt 46 from being disengaged from the fixing tube 41. Then, the adjusting plate 42 is slid along the inner wall of the fixed tube 41. The sliding of the adjusting plate 42 will drive the clamping plate 43 to slide. The sliding of the clamping plate 43 will drive the cable to move, thereby adjusting the height of the cable. During the adjustment process, the adjusting plate 42 will drive the extension plate 49 to move along the rectangular hole 48. The rectangular hole 48 reaches the position of limiting the extension plate 49, thereby preventing the adjusting plate 42 from escaping from the inner wall of the fixed tube 41. After the adjustment is completed, the bolt 46 is rotated in the opposite direction. When the bolt 46 abuts against the surface of the adjusting plate 42, the bolt 46 reaches the function of limiting the position of the adjusting plate 42. After the cable is limited, the rotating plate 53 is rotated in the opposite direction to make the rotating plate 53 contact with the cover plate 2, and then Then, the rotating plate 53 is slid along the surface of the cover plate 2. The rotating plate 53 will drive the sliding plate 52 to slide along the inner wall of the U-shaped plate 51. At the same time, the sliding of the rotating plate 53 will cause the card plate 54 to be inserted into the positioning frame 55 again. The positioning frame 55 reaches the function of limiting the position of the card plate 54, thereby preventing the rotating plate 53 from rotating. The movement of the card plate 54 will cause the magnetic piece 56 to contact the positioning frame 55. At this time, the magnetic piece 56 will be attracted to the surface of the positioning frame 55 by its own magnetic force, thereby limiting the position of the card plate 54. The rotating plate 53 can block the operating port 3 to prevent foreign matter from entering the wiring frame 1 and damaging the cable, thereby ensuring that the wiring frame 1 and the cover plate 2 can normally protect the cable.

[0037] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
