[0008] The cable clamp mechanism includes a positioning box disposed on one side of the wiring board. A pressing rod is symmetrically slidably connected to both ends of the positioning box, and an L-plate is symmetrically slidably connected inside the positioning box. One end of the pressing rod is fixedly connected to the L-plate, and a first compression spring is sleeved on the outside of one end of the pressing rod. A positioning groove is provided on one side of the wiring board, and a slot is provided inside the positioning groove. An insert plate is fixedly installed on one side of the bottom of the L-plate, and the outside of the insert plate is inserted into the inside of the slot. A rotating frame is rotatably connected to the side of the positioning box away from the wiring board. An N-shaped plate is hinged to the top of the rotating frame, and a protrusion is welded to one side of the rotating frame. A groove is provided on the bottom side of the N-shaped plate, and the protrusion and the groove are fastened together.
[0009] Preferably, a support plate is fixedly connected to one side of the rotating frame, and a plug rod is slidably connected inside the support plate. A second retraction spring is sleeved on the outside of the plug rod, and a retaining ring is fixedly connected to the bottom outer side of the plug rod. Insertion holes are opened on the top of the positioning box, and the bottom of the plug rod is inserted into the insertion hole.
[0010] Preferably, the positioning component includes a limiting box, which is symmetrically embedded inside one side of the clamping plate. A screw is rotatably connected inside the limiting box, and a push plate is slidably connected inside the limiting box. A threaded tube is fixedly connected to one side of the push plate, and one end of the screw is threadedly connected to the inside of the threaded tube.

[0011] Preferably, the positioning box has symmetrical guide grooves on its inner top side, and a guide block is fixedly installed on the top of the L plate, with the outer side of the guide block and the inner side of the guide groove being slidably connected.
[0012] Preferably, the bottom of the L-plate is slidably connected to the inside of the positioning groove.

[0014] Preferably, the outside of the insert block fits into the inside of the limiting groove, and the insert block is inserted into the limiting groove.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: A wiring device for a fire truck wiring harness assembly is described below: A pressing rod slides inside the positioning box, at which point the first contraction spring stretches. The movement of the pressing rod causes the L-plate to slide inside the positioning box. The operator then inserts the bottoms of the two sets of L-plates into the positioning slots. Utilizing the contraction force of the first contraction spring, the insert plate and slot are engaged. The operator then rotates the rotating frame on one side of the positioning box, and then rotates the N-type plate on one side of the rotating frame. At this point, the groove on one side of the N-type plate engages with the protrusion, thus enabling quick installation and disassembly of the positioning box, facilitating initial wiring harness inspection by the operator. The improved step-fixing and angle adjustment significantly enhances the wiring efficiency of fire truck wiring harnesses. Compared to existing technologies that use bolts and nuts for fixing, this method is more convenient and user-friendly. By rotating two sets of screws inside the limit box, the screws move the threaded tube, causing the push plate to slide inside the limit box. At this point, the retraction rod and the third retraction spring extend and reset, allowing multiple sets of inserts to connect with the limit slots. This enables rapid fixing of the limit connection plate, facilitating the quick assembly of the wiring board inside the bracket assembly. This greatly improves the efficiency of wiring harness assembly.
[0016] 1. The squeezing rod slides inside the positioning box, stretching the first contraction spring. The movement of the squeezing rod causes the L-plate to slide inside the positioning box. The operator inserts the bottoms of the two L-plates into the positioning slots. Then, the operator releases the squeezing rod, utilizing the contraction force of the first contraction spring to connect the insert plate to the slot, achieving rapid assembly of the positioning box. The operator then rotates the rotating frame on one side of the positioning box, placing the wiring harness inside the rotating frame. Next, the operator rotates the N-type plate on one side of the rotating frame, causing the groove and protrusion on one side of the N-type plate to engage, achieving initial positioning and angle adjustment of the wiring harness. Finally, the wiring harness is secured with straps, enabling rapid alignment. The installation and disassembly of the junction box facilitates the initial fixing and angle adjustment of the wiring harness by the staff, thereby greatly improving the wiring efficiency of the fire truck wiring harness. Compared with the bolt and nut fixing method in the existing technology, it is more convenient and brings convenience to the staff during use. At this time, the staff pulls the plug rod to slide inside the support plate. The movement of the plug rod drives the movement of the retaining ring. The retaining ring then compresses the second retraction spring. When the staff releases the plug rod, the return property of the second retraction spring allows one end of the plug rod to be inserted into the plug hole. This achieves the effect of quickly fixing and limiting the rotating frame, effectively preventing the wiring harness from shifting when adjusting the angle, and greatly improving the stability of the device during use.
[0017] 2. The operator inserts the connecting plate into the inside of the clamp. The operator then rotates two sets of screws inside the limiting box. Because the screws are threadedly connected to the threaded tube, the rotation of the screws causes the threaded tube to move. At this point, the push plate slides inside the limiting box. The retraction rod and the third retraction spring extend and reset, allowing multiple sets of inserts to connect with the limiting slots. This achieves the effect of quickly fixing the limiting connecting plate, facilitating the rapid assembly of the wiring board inside the bracket assembly. This makes it easier for the operator to subsequently route the wiring harness on the board, greatly improving the efficiency of wiring harness assembly and providing convenience for the operator during use.

[0030] Working principle: Before using this type of wiring harness assembly for fire trucks, it is necessary to check the overall condition of the device to ensure it can function properly. Figure 1 - Figure 6As shown, firstly, the operator adjusts the position of the positioning box 201 according to the fire truck wiring harness layout. Then, the operator presses the compression rods 202 with two fingers, causing the two sets of compression rods 202 to slide inside the positioning box 201. At this point, the first contraction spring 204 stretches, and the movement of the compression rods 202 causes the L-plates 203 to slide inside the positioning box 201. The operator then inserts the bottoms of the two sets of L-plates 203 into the positioning slots 205. Finally, the operator releases the compression rods 202, utilizing the contraction force of the first contraction spring 204... This allows the insertion plate 207 to connect with the slot 206, achieving rapid assembly of the positioning box 201. Then, the operator rotates the rotating frame 208 on one side of the positioning box 201, placing the wire harness inside the rotating frame 208. Next, the operator rotates the N-shaped plate 209 on one side of the rotating frame 208, causing the groove 211 on one side of the N-shaped plate 209 to engage with the protrusion 210, achieving initial positioning and angle adjustment of the wire harness. Finally, the automotive wire harness is secured with straps, enabling rapid alignment. The installation and disassembly of the positioning box 201 facilitates the initial fixing and angle adjustment of the wiring harness by the staff, thereby greatly improving the wiring efficiency of the fire truck wiring harness. Compared with the bolt and nut fixing method in the existing technology, it is more convenient and brings convenience to the staff during use. After the angle of the rotating frame 208 is adjusted, the staff pulls the insertion rod 213 to slide inside the support plate 212. At this time, the movement of the insertion rod 213 drives the movement of the retaining ring 215. The retaining ring 215 compresses the second contraction spring 214. Then, the staff releases the insertion rod 213, and the second contraction spring 214 returns to its original position, so that one end of the insertion rod 213 can be inserted into the insertion hole 216. This achieves the effect of quickly fixing and limiting the rotating frame 208, which can effectively prevent the wiring harness from shifting when adjusting the angle, greatly improving the stability of the device during use and bringing practicality to the staff. The movement of the L plate 203 drives the guide block 218 to slide inside the guide groove 217, which makes the movement of the L plate 203 more stable.
[0031] The operator inserts the connecting plate 102 into the inside of the clamping plate 103. At this time, the operator rotates the two sets of screws 302 inside the limiting box 301. Since the screws 302 are threadedly connected to the threaded tube 304, the rotation of the screws 302 drives the movement of the threaded tube 304. At this time, the push plate 303 slides inside the limiting box 301. At this time, the retraction rod 306 and the third retraction spring 307 extend and reset, thereby allowing the multiple sets of inserts 305 to be inserted into the limiting groove 308. This achieves the effect of quickly fixing the limiting connecting plate 102, which makes it easier for the operator to quickly assemble the wiring board 1 inside the bracket assembly 101. This facilitates the subsequent wiring of the wiring harness on the wiring board 1, greatly improves the wiring harness assembly efficiency, and brings convenience to the operator during use.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
