Description

Technical Field

[0001] This utility model relates to the technical field of wiring equipment for fire protection engineering, and more specifically, to a wiring mechanism for fire protection engineering. Background Technology

[0002] In fire protection engineering wiring, traditional cable pulling methods mostly rely on manual pulling of cables through various pipes and holes. Because cables are inherently flexible and lack effective guidance, they are prone to tangling and knotting during the pulling process, significantly reducing efficiency and increasing construction time and costs. Furthermore, in scenarios where the pulling device needs to be temporarily fixed to wall openings for operation, the lack of convenient and stable positioning methods often requires workers to use additional tools or manpower to maintain the device's position, making operation inconvenient and difficult to ensure stability, thus failing to meet the demands of efficient and precise fire protection engineering wiring.

[0003] To address at least some of the aforementioned problems, a wiring mechanism for fire protection engineering is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a cable threading mechanism for fire protection engineering, which is equipped with symmetrical limiting and guiding components. Through the cooperation of the two limiting and guiding components, the cable can be accurately guided to ensure that the cable passes through the center of the support ring and the threading hole set in the wall along a predetermined path.

[0005] A cable threading mechanism for fire protection engineering includes a support ring, on which symmetrically arranged brackets are fixed to the arc-shaped outer wall of the support ring. Each bracket is provided with a limit guide component on its upper side. There are two limit guide components, which are symmetrically arranged, and the two limit guide components form a cable guiding and threading function.

[0006] The limiting guide assembly includes a limiting shaft, a connecting block, a set screw, and a telescopic rod. The outer shell of the telescopic rod is fixed to the upper side of the bracket. The outer shell of the telescopic rod is threadedly connected to the set screw corresponding to the moving rod of the telescopic rod. The set screw can hold the moving rod of the telescopic rod. The end of the moving rod of the telescopic rod is fixedly connected to the connecting block. The two ends of the limiting shaft are rotatably connected inside the connecting block.

[0007] Furthermore, the cross-sections at both ends of the limiting shaft are larger than the cross-section in the middle, and the cross-sectional area of ​​the limiting shaft gradually increases from the middle to both ends.

[0008] Furthermore, the bracket is connected to a claw assembly, which includes a clamping plate, a swing rod, a column, a spring, a slider, and a guide rail. Both ends of the bracket are rotatably connected to one end of the swing rod, and the other end of each swing rod is fixedly connected to one end of the guide rail. A guide shaft is fixed within each guide rail, and each guide shaft passes through the slider. A column is fixed to the lower side of each slider, and a set of clamping plates evenly arranged from bottom to top is fixed to each column. Both ends of each slider are fixedly connected to one end of the spring, and the other end of the spring is fixedly connected to both ends of the guide rail. The spring loops around the guide shaft, and the swing rod is connected to a drive assembly.

[0009] Furthermore, the drive assembly includes a moving rod, a screw, a fixed block, a square block, and a stop block. The fixed block is fixed to the outer side of the middle part of the bracket. Each fixed block is rotatably connected to one end of the screw. Each screw is threadedly connected to the internal threaded ring at the center of the moving rod. Both ends of each moving rod pass through the square block. The stop block is fixed to both ends of each moving rod. Each square block is rotatably connected to the upper side of the other end of the corresponding swing rod.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are:

[0011] The cable threading mechanism used in this fire protection project is equipped with symmetrical limiting and guiding components. Through the cooperation of two limiting and guiding components, the cable can be accurately guided to ensure that the cable passes through the center of the support ring and the cable threading hole set in the wall along the predetermined path.

[0012] The telescopic rod in the limit guide assembly is ingeniously designed. The position of the limit shaft can be easily adjusted by loosening the set screw and pulling the telescopic rod according to the actual diameter of the cable, thus adapting to cables of different thicknesses.

[0013] The claw assembly, combined with the drive assembly, provides a reliable limiting function for the threading mechanism. The claw assembly can be firmly locked in the hole in the wall, and with the help of the spring and slider structure, the clamping plate can be finely adjusted according to the hole position to adapt to different hole sizes. The drive assembly further facilitates the operator to flexibly adjust the position of the clamping plate according to actual needs. Attached Figure Description

[0018] The following is in conjunction with the appendix Figure 1-2 The present invention will be further described in terms of the embodiments and implementation methods.

[0019] A cable threading mechanism for fire protection engineering includes a support ring 1. The arc-shaped outer wall of the support ring 1 is fixed with symmetrically arranged brackets 3. Each bracket 3 is provided with a limit guide component 2 on its upper side. There are two limit guide components 2 arranged symmetrically, and the two limit guide components 2 form a cable guiding and threading function.

[0020] The limiting guide assembly 2 includes a limiting shaft 201, a connecting block 202, a set screw 203, and a telescopic rod 204. The outer shell of the telescopic rod 204 is fixed on the upper side of the bracket 3. The outer shell of the telescopic rod 204 is threadedly connected to the set screw 203 corresponding to the moving rod 501 of the telescopic rod 204. The set screw 203 can hold the moving rod 501 of the telescopic rod 204. The end of the moving rod 501 of the telescopic rod 204 is fixedly connected to the connecting block 202. The two ends of the limiting shaft 201 are rotatably connected inside the connecting block 202.

[0021] The cross-sections at both ends of the limiting shaft 201 are larger than the cross-section in the middle, and the cross-sectional area of ​​the limiting shaft 201 gradually increases from the middle to both ends.

[0022] In this embodiment, the position of the limiting shaft 201 can be adjusted according to the diameter of the cable. Loosening the set screw 203 can pull the moving rod 501 of the telescopic rod 204 to move inside the housing, thereby realizing the movement of the connecting block 202 and the limiting shaft 201. After adjustment, tighten the set screw 203.

[0023] When using it for cable threading assistance, the cable is passed between the two limiting shafts 201 and through the center of the support ring 1. Pulling or pushing the cable moves the limiting shafts 201 and the auxiliary cable moves.

[0024] The bracket 3 is connected to the claw assembly 4. The claw assembly 4 includes a clamping plate 401, a swing rod 402, a column 403, a spring 404, a slider 405, and a guide rail 406. Both ends of the bracket 3 are rotatably connected to one end of the swing rod 402. The other end of each swing rod 402 is fixedly connected to one end of the guide rail 406. Each guide rail 406 has a guide shaft 4061 fixed inside it. Each guide shaft 4061 passes through the slider 405. The column 403 is fixed to the lower side of each slider 405. Each column 403 has a set of clamping plates 401 evenly arranged from bottom to top. Both ends of each slider 405 are fixedly connected to one end of the spring 404. The other end of the spring 404 is fixedly connected to both ends of the guide rail 406. The spring 404 is looped around the guide shaft 4061. The swing rod 402 is connected to the drive assembly 5.

[0025] In this embodiment, the claw assembly 4 is used to lock into the hole in the wall to limit the position of the device. The support ring 1 corresponds to the wire hole pre-opened in the wall. In use, by inserting the locking plate 401 of the claw assembly 4 into the hole in the wall, the locking plate 401 can be pulled according to the position of the hole to drive the column 403 to move. The column 403 drives the slider 405 to move along the guide shaft 4061 in the guide rail 406. The spring 404 undergoes elastic deformation to achieve fine adjustment of the position of the locking plate 401, making it convenient for the locking plate 401 to lock into the hole.

[0026] The drive assembly 5 includes a moving rod 501, a screw 502, a fixing block 503, a square block 504, and a stop block 505. The fixing blocks 503 are fixed to the outer side of the middle part of the bracket 3. Each fixing block 503 is rotatably connected to one end of the screw 502. Each screw 502 is threadedly connected to the internal thread ring at the center of the moving rod 501. Both ends of each moving rod 501 pass through the square block 504. The stop blocks 505 are fixed to both ends of each moving rod 501. Each square block 504 is rotatably connected to the upper side of the other end of the corresponding swing rod 402.

[0027] The drive assembly 5 can drive the swing plate to swing, and can adjust the position of the card plate 401 according to the position of the hole. Rotating the screw 502 can drive the moving rod 501 to move, the moving rod 501 can drive the block 504 to move, the block 504 can drive the swing rod 402 to swing, and finally drive the guide rail 406 and the card plate 401 to swing, so as to realize the position adjustment of the card plate 401.

[0028] The working process of this utility model is as follows:

[0029] Depending on the construction location, bring the wire threading mechanism to the vicinity of the wall hole and observe the cable diameter. If the position of the limit shaft 201 needs to be adjusted, rotate the screw 502. The screw 502 drives the moving rod 501 to move, the moving rod 501 drives the block 504 to move, and the block 504 drives the swing rod 402 to swing, so that the guide rail 406 and the clamping plate 401 swing to the optimal position. Hold the swing rod 402 and align the clamping plate 401 of the claw assembly 4 with the wall hole. Slowly push the clamping plate 401. If resistance is encountered, pull the clamping plate 401 according to the position of the hole. The column 403 drives the slider 405 to move along the guide shaft 4061 in the guide rail 406. The spring 404 elastically deforms and fine-tunes the position of the clamping plate 401 until the clamping plate 401 is firmly inserted into the hole. Loosen the set screw 203, pull the telescopic rod 204 and the moving rod 501 to the appropriate position so that the spacing of the limiting shaft 201 matches the cable, then tighten the set screw 203, and pass one end of the cable between the two limiting shafts 201, ensuring that the cable passes through the center of the support ring 1. Align the center of the support ring with the cable hole opened in the wall, so that the cable is inserted into the center of the cable hole. The operator stands in the appropriate position and pulls or pushes the cable. At this time, the limiting shaft 201 will rotate with the movement of the cable, assisting the cable to smoothly pass through the predetermined path and complete the cable threading operation.
