Description

Technical Field

[0001] This utility model belongs to the field of wire harness fixing technology, and specifically relates to a snap-lock fixing device for preventing loosening of heavy-duty truck wire harnesses. Background Technology

[0002] As the core transmission carrier of the electrical system of heavy-duty trucks, the wiring harness needs to maintain high stability in power distribution and signal control. Since vehicles are subjected to dynamic loads such as road bumps and multi-directional impacts for a long time, the mechanical reliability of its fixing device directly determines the safety threshold and long-term operating capability of the electrical system, becoming a key link in controlling the overall vehicle failure rate.

[0003] Currently, wiring harness fixing methods generally employ a composite structure combining clips and bolts, where clips are rigidly installed on pre-set points on the vehicle frame via bolt connections. However, the multi-directional mechanical vibrations generated by heavy-duty trucks under continuous dynamic loads can easily lead to a decrease in bolt preload, causing potential structural loosening. Simultaneously, bolt threads are highly susceptible to fatigue wear and stripping. This not only requires significant time and specialized tools to remove the damaged bolts but may also cause the bolts to jam, making it difficult to separate the clips from the mounting base. This significantly increases the difficulty and time required for wiring harness replacement, severely impacting vehicle maintenance efficiency. Utility Model Content

[0004] To address the problems of bolts easily loosening under vibration and the difficulty in disassembling spirals after they strip, this utility model proposes a heavy-duty cable harness anti-loosening snap-locking device to overcome the aforementioned technical problems in existing related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a buckle-type fixing device for preventing loosening of heavy truck wire harnesses, including an installation component. The installation end of the installation component is provided with a limit component, the front side of the installation component is provided with a clamping component, and the moving end of the clamping component is provided with an elastic connecting component.

[0007] By mounting the mounting assembly on the frame, the clamping assembly is connected to the workshop. The elastic connection assembly is used to connect the fixed end and the movable end of the clamping assembly, so that the clamping assembly can clamp and fix the wire harness.

[0008] Furthermore, the mounting assembly includes a mounting plate, and mounting holes are provided at the corners of the mounting plate, with bolts threaded into the internal parts of the mounting holes.

[0009] Furthermore, the limiting component includes limiting holes, which are opened on the head of the bolt. A limiting rod is movably connected inside the limiting hole. An L-shaped limiting plate is fixedly connected to one end of the limiting rod. A fixing rod is provided on the top of the L-shaped limiting plate. A fixing hole is opened on the top of the mounting plate corresponding to the fixing rod.

[0010] Furthermore, a storage tube is fixedly connected to the top of the L-shaped limiting plate, a movable disk is movably connected to the top of the storage tube, a movable rod is fixedly connected to the top of the movable disk, the top end of the movable rod passes through the storage tube and is fixedly connected to a pull plate, the fixed rod is fixedly connected to the pull plate, and a fixed spring is fixedly connected between the movable disk and the inner wall of the storage tube.

[0011] Furthermore, the clamping assembly includes a placement seat, which is fixedly installed on the front of the mounting plate. A rubber pad is fixedly connected to the inner wall of the placement seat, and a movable frame is provided on the outer side of the placement seat. An arc-shaped clamping block is fixedly connected to the inner wall of the movable frame.

[0012] Furthermore, the elastic connection component includes a connection groove, which is opened on the outside of the placement seat and passes through the movable frame. A connection plate is movably connected inside the connection groove, and a push plate is fixedly connected to one side of the connection plate. Multiple connection grooves are arrayed on the outside of the placement seat.

[0013] Furthermore, the movable frame has a storage cavity inside, and a connecting plate is movably connected inside the storage cavity. A connecting rod is fixedly connected to one side of the connecting plate, and one end of the connecting rod passes through the movable frame and is fixedly connected to the push plate. A connecting spring is fixedly connected between the connecting plate and the inner wall of the storage cavity.

[0014] This utility model has the following beneficial effects:

[0015] This invention places the wire harness inside the fixed end of the clamping assembly, and then moves the movable end of the clamping assembly, thereby fixing and clamping the wire harness between the fixed end and the movable end. Then, the connecting end of the elastic connecting assembly connects the fixed end and the connecting end together under the push of the spring end. In the above configuration, the buffering characteristic of the spring end can effectively absorb the vibration energy generated during vehicle operation, preventing the connecting end from displacing significantly due to vibration, thus allowing the clamping assembly to continuously and stably clamp and fix the wire harness. At the same time, when releasing the fixing of the wire harness, the movable end can be separated from the fixed end by simply pulling the connecting end, making it convenient to replace the wire harness.

[0016] This invention uses bolts to fix the mounting plate to the vehicle frame. Then, the limiting rod is moved into the limiting hole on the bolt. When the fixing rod is vertically aligned with the fixing hole, the fixing spring pushes the fixing rod into the fixing hole via a moving plate, a moving rod, and a pull plate. At this point, the fixing rod is fixed by the L-shaped limiting plate, and the limiting rod, through the limiting hole, can limit the bolt. This setup forms a multi-layered limiting mechanism, effectively preventing the bolt from rotating when the vehicle vibrates, thus ensuring that the mounting plate and the vehicle frame remain firmly connected.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0029] Please see Figures 1-6 As shown, this utility model is a buckle-type fixing device for preventing loosening of heavy truck wire harnesses, including an installation component 1. The installation end of the installation component 1 is provided with a limiting component 2, the front of the installation component 1 is provided with a clamping component 3, and the moving end of the clamping component 3 is provided with an elastic connecting component 4.

[0030] By mounting the mounting assembly 1 on the frame, the clamping assembly 3 is connected to the workshop. The elastic connecting assembly 4 is used to connect the fixed end and the moving end of the clamping assembly 3, so that the clamping assembly 3 can clamp and fix the wire harness.

[0031] By installing the mounting component 1 at a suitable position on the frame, and then placing the wire harness directly inside the fixed end of the clamping component 3, the moving end of the clamping component 3 is moved, so that the fixed end and the moving end cooperate to clamp the wire harness. Then, the spring end of the elastic connecting component 4 can push the connecting end, so that the connecting end can connect the fixed end that clamps and fixes the wire harness together.

[0032] By placing the wire harness inside the fixed end of the clamping assembly 3 and then moving the movable end of the clamping assembly 3, the fixed end and the movable end can clamp the wire harness in place. Then, the connecting end of the elastic connecting assembly 4 connects the fixed end and the connecting end together under the push of the spring end. In the above configuration, the buffering characteristic of the spring end can effectively absorb the vibration energy generated during vehicle operation, preventing the connecting end from displacing significantly due to vibration. This allows the clamping assembly 3 to continuously and stably clamp and fix the wire harness. At the same time, when releasing the wire harness, simply pulling the connecting end can separate the movable end from the fixed end, making it convenient to replace the wire harness.

[0033] In one embodiment, the mounting assembly 1 includes a mounting plate 101, and mounting holes 102 are provided at the corners of the mounting plate 101. Bolts 103 are threaded into the mounting holes 102.

[0034] By placing the mounting plate 101 in a suitable position on the frame, the bolt 103 secures the mounting plate 101 to the frame through the mounting hole 102; with the support of the mounting plate 101, the clamping assembly 3 can be connected to the frame.

[0035] In one embodiment, the limiting component 2 includes a limiting hole 201, which is provided on the head of the bolt 103. A limiting rod 202 is movably connected inside the limiting hole 201. An L-shaped limiting plate 203 is fixedly connected to one end of the limiting rod 202. A fixing rod 204 is provided on the top of the L-shaped limiting plate 203. A fixing hole 205 is provided on the top of the mounting plate 101 corresponding to the fixing rod 204.

[0036] After the mounting plate 101 is fixed, the limiting holes 201 on the two bolts 103 on one side of the mounting plate 101 are aligned with each other. At this time, the limiting rod 202 is moved into the two limiting holes 201. When the inner wall of the L-shaped limiting plate 203 comes into contact with one of the bolts 103, the fixing rod 204 is aligned vertically with the fixing hole 205. At this time, the fixing rod 204 is moved directly into the fixing hole 205, so that the fixing rod 204 limits the L-shaped limiting plate 203 through the fixing hole 205. At the same time, the L-shaped limiting plate 203 can limit the two bolts 103 through the limiting rod 202 and the limiting hole 201. This setting ensures that the two bolts 103 will not rotate when the vehicle vibrates, so that the mounting plate 101 can be firmly connected to the frame.

[0037] In one embodiment, for the L-shaped limiting plate 203, a storage cylinder 206 is fixedly connected to the top of the L-shaped limiting plate 203, a movable disk 207 is movably connected to the top of the storage cylinder 206, a movable rod 208 is fixedly connected to the top of the movable disk 207, the top end of the movable rod 208 passes through the storage cylinder 206 and is fixedly connected to a pull plate 209, the fixed rod 204 is fixedly connected to the pull plate 209, and a fixed spring 210 is fixedly connected between the movable disk 207 and the inner wall of the storage cylinder 206.

[0038] The fixed spring 210 pushes the moving rod 208 downward through the moving plate 207. The downward-moving moving rod 208 then pushes the fixed rod 204 downward through the pull plate 209, allowing the fixed rod 204 to move directly into the fixed hole 205. The fixed spring 210 prevents the fixed rod 204 from moving out of the fixed hole 205 at will, thus ensuring the stability of the fixed rod 204 when fixing the L-shaped limiting plate 203. At the same time, when the limiting rod 202 is moved out of the limiting hole 201, it can be pulled upward directly to the pull plate 209, making the operation relatively convenient.

[0039] In one embodiment, the clamping assembly 3 includes a placement seat 301, which is fixedly installed on the front of the mounting plate 101. A rubber pad 302 is fixedly connected to the inner wall of the placement seat 301, and a movable frame 303 is provided on the outer side of the placement seat 301. An arc-shaped clamping block 304 is fixedly connected to the inner wall of the movable frame 303.

[0040] By placing the wire harness inside the placement base 301, and then fitting the moving frame 303 onto the outside of the placement base 301 and moving it upwards, the arc-shaped clamping block 304 and the rubber pad 302 can cooperate to clamp and fix the wire harness.

[0041] In one embodiment, the elastic connection component 4 includes a connection groove 401, which is formed on the outside of the placement seat 301 and extends through the movable frame 303. A connection plate 402 is movably connected inside the connection groove 401, and a push plate 403 is fixedly connected to one side of the connection plate 402. Multiple connection grooves 401 are arrayed on the outside of the placement seat 301.

[0042] After the wire harness is clamped and fixed, the connecting plate 402 is pushed by the pushing plate 403, so that the connecting plate 402 can move into the corresponding connecting groove 401. At this time, the connecting plate 402 can connect the moving frame 303 and the placement seat 301 together through the connecting groove 401, so that the rubber pad 302 and the arc-shaped clamping block 304 always maintain the clamping and fixing of the wire harness. Since there are multiple connecting grooves 401, this arrangement allows the arc-shaped clamping block 304 and the rubber pad 302 to clamp and fix wire harnesses of various specifications. Since the arc-shaped clamping block 304 and the rubber pad 302 have a certain degree of elasticity, when the connecting plate 402 and the connecting groove 401 are not aligned, only a large squeezing force needs to be applied to the moving frame 303 to make the moving frame 303 move slightly again, so that the connecting plate 402 and the connecting groove 401 can be aligned with each other.

[0043] In one embodiment, for the aforementioned movable frame 303, a storage cavity 404 is provided inside the movable frame 303, a connecting plate 405 is movably connected inside the storage cavity 404, a connecting rod 406 is fixedly connected to one side of the connecting plate 405, one end of the connecting rod 406 passes through the movable frame 303 and is fixedly connected to the push plate 403, and a connecting spring 407 is fixedly connected between the connecting plate 405 and the inner wall of the storage cavity 404.

[0044] The connecting spring 407 can push the connecting rod 406 through the connecting plate 405. The moving connecting rod 406 then pushes the connecting plate 402 into the connecting groove 401 through the push plate 403. In the above configuration, under the elastic force of the connecting spring 407, the connecting plate 402 will not move out of the connecting groove 401 at will. At the same time, when the wire harness is taken out from between the placement seat 301 and the moving frame 303, the push plate 403 can be pushed directly to separate the placement seat 301 from the moving frame 303. The whole operation is relatively convenient.

[0045] Through the above technical solution, 1. By placing the wire harness inside the fixed end of the clamping component 3, and then moving the movable end of the clamping component 3, the fixed end and the movable end can clamp the wire harness securely. Then, the connecting end of the elastic connecting component 4 connects the fixed end and the connecting end together under the push of the spring end. In the above setting, the buffering characteristic of the spring end can effectively absorb the vibration energy generated during vehicle operation, preventing the connecting end from displacing significantly due to vibration, thus allowing the clamping component 3 to continuously and stably clamp and fix the wire harness. At the same time, when releasing the wire harness, simply pulling the connecting end can separate the movable end from the fixed end, making it convenient to replace the wire harness. 2. After the mounting plate 101 is fixed to the frame by bolts 103, the limiting rod 202 is moved into the limiting hole 201 opened on the bolt 103. When the fixing rod 204 is aligned vertically with the fixing hole 205, the fixing spring 210 pushes the fixing rod 204 into the fixing hole 205 through the moving plate 207, the moving rod 208 and the pull plate 209. At this time, the fixing rod 204 is fixed to the limiting rod 202 by the L-shaped limiting plate 203, and the limiting rod 202 can limit the bolt 103 through the limiting hole 201. The above settings can form a multi-layer limiting mechanism, which can effectively prevent the bolt 103 from rotating when the vehicle vibrates, thereby ensuring that the mounting plate 101 and the frame always maintain a firm connection.
