Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to an adjustable ladder-shaped bridge. Background Art

[0002] Trapezoidal bridge refers to a support structure used to support cables, pipelines and other facilities, usually made of metal or other materials, with a trapezoidal shape. It is mainly used to support and protect power cables, communication cables, pipelines and other facilities to ensure their safe layout and transmission in buildings or other structures.

[0003] When installing a ladder bridge, it is necessary to accurately measure the required length and cut the ladder bridge to ensure that it meets the actual installation requirements after cutting. When cutting and adjusting the ladder bridge, a certain degree of material waste will occur, especially when the ladder bridge needs to be cut from a longer length to a shorter length, which may cause some excess material. After cutting, the two sections of the ladder bridge need to be reconnected, and the firmness of the connection cannot be guaranteed.

[0004] Therefore, the improvement of adding an adjustable device to the ladder bridge becomes a technical problem that needs to be overcome by those skilled in the art. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0022] See also Figure 1-6 , the utility model provides a technical solution:

[0023] An adjustable trapezoidal bridge comprises a bridge body 100, guide rails 200 are arranged on both sides of the bridge body 100, a telescopic mechanism 300 is arranged at one end of the bridge body 100, a limiting mechanism 400 for limiting the position of the telescopic mechanism 300 is arranged on one side of the guide rail 200, a fixing device 500 for reinforcing the connection between the guide rail 200 and the telescopic mechanism 300 is arranged on one side of the guide rail 200, the fixing device 500 comprises a telescopic motor 510, an extrusion block 520, a fixed block 530 and a spring 540, the extrusion block 520 is clamped and arranged on the upper part of the telescopic motor 510, the fixed block 530 is fixedly arranged on the bottom end of the telescopic motor 510, and the spring 540 is arranged between the extrusion block 520 and the fixed block 530.

[0024] In the present embodiment, by installing a retractable mechanism 300 at one end of the bridge body 100, the length of the bridge can be adjusted to meet different wiring requirements. By installing guide rails on both sides of the bridge body 100, the movement of the retractable mechanism 300 is guided. A limiting mechanism 400 for limiting the retractable mechanism 300 is installed on one side of the guide rail 200 to prevent it from exceeding a predetermined range. The fixing device 500 is used to stabilize the connection between the guide rail 200 and the retractable mechanism 300 to ensure the stability and reliability of the bridge. The extrusion block 520 is controlled by the retractable motor 510 to apply pressure to the connecting component spring 540 to ensure the firmness of the connection. The fixing block 530 is used to stabilize the position of the retractable motor 510 on the guide rail 200 to realize the retractable function of the bridge. The limiting mechanism 400 and the fixing device 500 are used to ensure the stability and safety of the bridge during use.

[0025] Specifically, a telescopic rod 521 is disposed in the middle of the extrusion block 520 , and a positioning groove 531 corresponding to the telescopic rod 521 is opened in the middle of the fixing block 530 .

[0026] In this embodiment, the telescopic rod 521 is located in the middle of the extrusion block 520, used to connect the extrusion block 520 and the fixed block 530, and is positioned in the middle of the fixed block 530. The positioning groove 531 is used to accommodate the telescopic rod 521 to ensure that the connection position between the telescopic rod 521 and the fixed block 530 is accurate and stable.

[0027] Specifically, a first limiting groove 210 is formed on the side wall of one side of the guide rail 200 , and a second limiting groove 220 is formed on the top of one side of the guide rail 200 .

[0028] In this embodiment, the first limit groove 210 is located on the side wall of one side of the guide rail 200, and is used to limit the horizontal movement range of the telescopic mechanism 300 on the guide rail 200 to ensure that it does not exceed a specific position range. The second limit groove 220 is located at the top of one side of the guide rail 200, and is used to limit the vertical movement range of the telescopic mechanism 300 on the guide rail 200. It is used for the fixing device 500 to fix the telescopic mechanism 300 to prevent it from exceeding the upper limit position of the guide rail 200, which helps to ensure that the telescopic mechanism 300 remains in a safe and appropriate position during the use of the bridge.

[0029] Specifically, the telescopic mechanism 300 includes a telescopic slide rail 310 and a cross frame 320. The telescopic slide rail 310 is fixedly arranged on both sides of the bridge frame body 100. Locking nuts 311 are fixedly arranged at both ends of the telescopic slide rail 310. Several groups of limiting holes 312 are opened on the side of the telescopic slide rail 310. The cross frame 320 is arranged between the telescopic slide rails 310 and its position corresponds to the limiting holes 312.

[0030] In this embodiment, the telescopic slide rail 310 is fixedly connected to both sides of the bridge body 100 for supporting and guiding the movement of the telescopic mechanism 300. Locking nuts 311 are provided at both ends of the telescopic slide rail 310 for fixing the position of the telescopic slide rail 310 to prevent accidental movement during use. Several groups of limiting holes 312 are provided on the side of the telescopic slide rail 310. These limiting holes 312 are used to limit the position range of the cross frame 320 on the telescopic slide rail 310. The cross frame 320 is arranged between the telescopic slide rails 310, and its position corresponds to the limiting holes 312 to ensure that the cross frame 320 stays at a specific position, thereby realizing the adjustable length of the bridge. At the same time, the corresponding positions of the limiting holes 312 and the cross frame ensure the stability and safety of the bridge 320 at different lengths.

[0031] Specifically, the limiting mechanism 400 is disposed between the first limiting grooves 210 , and includes a rocker 410 and a locking bolt 420 . The rocker 410 is closely attached to the outer side of the guide rail 200 , and the locking bolt 420 is inserted into the locking nut 311 .

[0032] In this embodiment, the limiting mechanism 400 is set between the first limiting grooves 210 to limit the movement range of the bridge body 100. The rocker 410 is close to the outer side of the guide rail 200 to limit the movement range of the bridge body 100 toward the inner side of the guide rail 200. When the bridge body 100 moves to the limiting position, the rocker 410 rotates to allow the locking bolt 420 to be inserted into the locking nut 311 of the guide rail 200 to prevent further movement. Once the bridge body 100 moves to the limiting position, the locking bolt 420 will be adjusted to the corresponding position, thereby locking the rocker 410 to ensure that the bridge body 100 remains in the limiting position. The limiting mechanism 400 can effectively limit the movement range of the bridge body 100 to ensure that it stays at a specific position to meet specific work needs or safety requirements.

[0033] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
