Description

Technical Field

[0001] This utility model relates to the field of wiring harness fixing technology, and more specifically to a reusable taillight wiring harness fixing device. Background Technology

[0002] Taillights are important automotive components, typically red lights installed at the rear of the vehicle. These primarily serve as red warning lights to following vehicles, amber lights for directional indication, and reversing lights for enhanced visibility. To facilitate installation and maintenance, taillights are usually connected to a control terminal via wiring harnesses. Since these harnesses are often quite long, and to prevent damage from movement within the vehicle, wiring harness securing devices are used. These devices fix the multiple wires to the vehicle's sheet metal, resulting in a more aesthetically pleasing and organized wiring harness.

[0003] Insufficiency of existing technology: However, existing wire harness fixing devices mostly use cable ties to fix the wire harness. However, when in use, the cable ties are close to the side of the wire harness, which is inconvenient to disassemble and install. Maintenance is time-consuming and laborious. At the same time, it is impossible to accurately determine the pressure of the cable ties on the wire harness, which can easily lead to insecure fixing or damage to the wire harness due to excessive pressure. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a taillight wiring harness fixing device that can be used multiple times, so as to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a reusable taillight wiring harness fixing device, comprising an installation mechanism, and further comprising: a fixing mechanism, a warning mechanism, and a wiring harness body. The top end of the installation mechanism is fixedly connected to the bottom end of the fixing mechanism, the bottom end of the warning mechanism is fixedly connected to the top end of the fixing mechanism, and the side of the wiring harness body is movably connected to the side of the fixing mechanism. The installation mechanism includes an installation base, and the fixing mechanism includes a storage tube. The top end of the installation base is fixedly connected to the bottom end of the storage tube, and a strap is fixedly connected to the side of the storage tube. A movable tube is movably sleeved on the inner wall of the bottom end of the storage tube, and the side of the movable tube is fixedly connected to one end of the strap. A through groove is provided on the side of the storage tube corresponding to the position of the strap. A rotating shaft is movably sleeved on the top end of the storage tube. A fourth locking tooth is fixedly connected to the inner wall of the side of the movable tube, and a second locking tooth is fixedly connected to the side of the rotating shaft. The side of the second locking tooth and the side of the fourth locking tooth mesh with each other.

[0006] Furthermore, a first return spring is fixedly connected to the inner wall of the bottom end of the storage tube at the position corresponding to the movable tube. The top end of the first return spring is tightly attached to the bottom end of the rotating shaft. A partition is fixedly connected to the inner wall of the side of the storage tube. A fixed tube is fixedly connected to the top end of the partition. A third locking tooth is fixedly connected to the inner wall of the side of the fixed tube. A first locking tooth is fixedly connected to the side of the rotating shaft. The side of the first locking tooth and the side of the third locking tooth mesh with each other.

[0007] Furthermore, the top of the third locking tooth is in close contact with the inner wall of the top of the storage tube, and both the bottom of the third locking tooth and the top of the first locking tooth are chamfered.

[0008] Furthermore, the length of the second locking tooth is twice that of the third locking tooth and the first locking tooth, and the first return spring is in a compressed state.

[0009] Furthermore, a turntable is fixedly connected to the bottom end of the mounting base, a base is movably sleeved on the bottom end of the turntable, a first fixing bolt is threaded to the bottom end of the base, an arc-shaped groove is provided on the top end of the turntable, and a second fixing bolt is threaded to the top end of the base corresponding to the position of the arc-shaped groove.

[0010] Furthermore, the prompting mechanism includes an indicator light, the side of which is fixedly connected to the side of the mounting base. A second mounting hole is provided at the top of the storage tube, a second return spring is fixedly connected to the bottom of the second mounting hole, a pressure block is fixedly connected to the top of the second return spring, a push rod is fixedly connected to the bottom of the pressure block, and a touch switch is movably connected to the bottom of the second mounting hole.

[0011] Furthermore, a first mounting hole is provided at the bottom end of the second mounting hole, and a buffer spring is fixedly connected to the bottom end of the first mounting hole. The top end of the buffer spring is fixedly connected to the bottom end of the touch switch.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model involves passing the wire harness body that needs to be fixed through the binding strap and pressing down on the rotating shaft. This causes the first locking tooth to move downward with the rotating shaft and separate from the third locking tooth. Rotating the rotating shaft causes the movable cylinder to rotate through the constant engagement of the second and fourth locking teeth. The binding strap is wrapped around the movable cylinder to tighten the binding strap, making it tightly adhere to the side of the wire harness body and fix the wire harness body. When the rotating shaft is released, the first return spring pushes the rotating shaft upward, causing the first locking tooth to engage with the third locking tooth and fix the rotating shaft and the binding strap. To disassemble, simply rotate the rotating shaft in the opposite direction. The operation is simple, which helps to improve work efficiency, and it can be reused to avoid waste.

[0014] 2. This utility model uses a rotating turntable to maintain the mounting base at a suitable angle, and then tightens the second fixing bolt so that the second fixing bolt is tightly attached to the top of the turntable to fix the turntable. This helps to ensure that the wire harness is fixed and then tidied up, making it convenient for maintenance.

[0015] 3. In this utility model, the pressure block is pressed tightly against the side of the wire harness body, causing the pressure block to drive the push rod to move downward and contact the touch switch, so that the indicator light changes from red to green, indicating that the wire harness body is firmly fixed and the tightening of the strap stops. This helps to avoid damage to the wire harness due to excessive pressure and prevents the wire harness from falling off. Attached Figure Description

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The reusable taillight wiring harness fixing device involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Reference Figures 1 to 5 This utility model provides a reusable taillight wiring harness fixing device, including an installation mechanism 1, a fixing mechanism 2, a warning mechanism 3, and a wiring harness body 4. The top end of the installation mechanism 1 is fixedly connected to the bottom end of the fixing mechanism 2, the bottom end of the warning mechanism 3 is fixedly connected to the top end of the fixing mechanism 2, and the side of the wiring harness body 4 is movably connected to the side of the fixing mechanism 2. The installation mechanism 1 includes an installation base 103, and the fixing mechanism 2 includes a storage tube 201. The top end of the installation base 103 is fixedly connected to the bottom end of the storage tube 201. A strap 202 is fixedly connected to the side of the storage tube 201, and a movable tube 209 is movably sleeved on the inner wall of the bottom end of the storage tube 201. The side of the movable tube 209 is fixedly connected to one end of the strap 202, and the side of the storage tube 201 corresponds to the strap 202. A through slot 207 is provided at position 02. A rotating shaft 203 is movably sleeved at the top of the storage tube 201. A fourth locking tooth 212 is fixedly connected to the inner side wall of the movable tube 209. A second locking tooth 208 is fixedly connected to the side of the rotating shaft 203. The side of the second locking tooth 208 and the side of the fourth locking tooth 212 mesh with each other. The fixed wire harness body 4 is passed through the binding strap 202. Rotating the rotating shaft 203 causes the movable tube 209 to rotate through the meshing of the second locking tooth 208 and the fourth locking tooth 212, so that the binding strap 202 is wrapped around the movable tube 209, so that the binding strap 202 is slowly tightened and the side of the binding strap 202 is pressed tightly against the side of the binding strap 202 to fix the wire harness body 4. When disassembling, rotate the rotating shaft 203 in the opposite direction to release the binding strap 202, so that the binding strap 202 is loosened and disassembly is convenient.

[0024] The storage tube 201 has a first return spring 210 fixedly connected to the inner wall of its bottom end, corresponding to the position of the movable tube 209. The top end of the first return spring 210 is close to the bottom end of the rotating shaft 203. The storage tube 201 has a partition 204 fixedly connected to the inner wall of its side. The partition 204 has a fixed tube 205 fixedly connected to its top end. The fixed tube 205 has a third locking tooth 211 fixedly connected to the inner wall of its side. The rotating shaft 203 has a first locking tooth 206 fixedly connected to its side. The side of the first locking tooth 206 and the side of the third locking tooth 211 mesh with each other. After the strap 202 fixes the wire harness body 4, the first return spring 210 pushes the rotating shaft 203 to move upward, so that the first locking tooth 206 and the third locking tooth 211 mesh with each other, fixing the rotating shaft 203 and preventing the rotating shaft 203 from driving the movable tube 209 to rotate, and fixing the length of the strap 202.

[0025] The top of the third tooth 211 is close to the inner wall of the top of the storage tube 201. The bottom of the third tooth 211 and the top of the first tooth 206 are both chamfered to facilitate the first tooth 206 to move upward with the rotating shaft 203 and be inserted into the gap of the third tooth 211.

[0026] The length of the second locking tooth 208 is twice that of the third locking tooth 211 and the first locking tooth 206. When the first return spring 210 is in a compressed state, the second locking tooth 208 and the fourth locking tooth 212 are always engaged with each other when the first locking tooth 206 is separated from or engaged with the third locking tooth 211.

[0027] The mounting base 103 is fixedly connected to a turntable 106 at its bottom end. A base 101 is movably sleeved on the bottom end of the turntable 106. A first fixing bolt 102 is threadedly connected to the bottom end of the base 101. An arc-shaped groove 104 is provided at the top end of the turntable 106. A second fixing bolt 105 is threadedly connected to the top end of the base 101 at the position corresponding to the arc-shaped groove 104. The fixing device is installed in a suitable position inside the car by means of the first fixing bolt 102. The turntable 106 is rotated to keep the mounting base 103 at a suitable angle. Then the second fixing bolt 105 is tightened so that the second fixing bolt 105 is close to the top end of the turntable 106 to fix the turntable 106.

[0028] The indicator mechanism 3 includes an indicator light 301, the side of which is fixedly connected to the side of the mounting base 103. The top of the storage tube 201 has a second mounting hole 305, the bottom of which is fixedly connected to a second return spring 306. The top of the second return spring 306 is fixedly connected to a pressure block 302, the bottom of which is fixedly connected to a push rod 303. The bottom of the second mounting hole 305 is movably connected to a touch switch 307. When fixing the wire harness body 4, the pressure block 302 is pressed against the side of the wire harness body 4, causing the pressure block 302 to drive the push rod 303 to move downward and contact the touch switch 307, causing the indicator light 301 to change from red to green, indicating that the wire harness body 4 is firmly fixed and the tightening of the strap 202 is stopped.

[0029] The bottom end of the second mounting hole 305 is provided with a first mounting hole 304. A buffer spring 308 is fixedly connected to the bottom end of the first mounting hole 304. The top end of the buffer spring 308 is fixedly connected to the bottom end of the touch switch 307. When the push rod 303 contacts the touch switch 307, the buffer spring 308 contracts, causing the touch switch 307 to move downward a certain distance, thus buffering the touch switch 307.

[0030] The working principle of this utility model is as follows: The base 101 is installed in a suitable position inside the car by the first fixing bolt 102. The turntable 106 is rotated to keep the mounting base 103 at a suitable angle. Then, the second fixing bolt 105 is tightened so that the second fixing bolt 105 is close to the top of the turntable 106 to fix the turntable 106. The wire harness body 4 to be fixed is passed through the strap 202 and the rotating shaft 203 is pressed down to make the first locking tooth 206 move down with the rotating shaft 203 and separate from the third locking tooth 211. The rotating shaft 203 drives the movable cylinder 209 to rotate through the constant meshing of the second locking tooth 208 and the fourth locking tooth 212. The strap 202 is wrapped around the movable cylinder 209 and tightened so that the strap 202 is close to the car body. The side of the wire harness body 4 is fixed to the wire harness body 4. When the wire harness body 4 is firmly fixed, the side of the wire harness body 4 contacts the top of the pressure block 302, causing the pressure block 302 to drive the push rod 303 to move downward and contact the touch switch 307, causing the indicator light 301 to change from red to green, indicating that the wire harness body 4 is firmly fixed. When the rotating shaft 203 is released, the first return spring 210 pushes the rotating shaft 203 to move upward, so that the first locking tooth 206 and the third locking tooth 211 mesh with each other, fixing the rotating shaft 203 and the strap 202. When it is necessary to disassemble the wire harness body 4, press the rotating shaft 203 downward and rotate the rotating shaft 203 in the opposite direction to release the strap 202 from the movable tube 209, and then remove the wire harness body 4.
