Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted road inspection wiring harness protection technology, and in particular to a vehicle-mounted road inspection wiring harness interface protection device. Background Technology

[0002] Vehicle wiring harnesses refer to the wiring harnesses used in automobiles to connect and manage various electrical and electronic systems. They are protected by protective devices at the wiring harness interfaces to ensure the stability of the wiring harness connections during inspection.

[0003] Among them, a search revealed Chinese patent CN221240085U, which discloses a vehicle communication harness protection device. The aforementioned patent uses a folded tube structure to achieve the harness protection function. However, the folded tube is a complete unit, which makes it inconvenient to fit onto the harness. Furthermore, the folded tube cannot be fixedly connected to the harness, making it easy for the folded tube to loosen when fitted onto the harness. As a result, the folded tube does not provide good protection for the harness. Therefore, in order to advance industry technology, better realize the protection function of vehicle road inspection harness interfaces, and improve core technology competitiveness, this application proposes a new implementation scheme that differs from the existing protection device and harness connection structure and protection structure. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of existing protection devices being inconvenient to install and having easy loosening of the connection with the wiring harness during use, and to propose a vehicle-mounted road inspection wiring harness interface protection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A vehicle-mounted road inspection wiring harness interface protection device includes a protection component. The protection component includes a first arc shell and a second arc shell, which are rotatably connected. The first arc shell contains two sets of fixing components, each including a support block. The support block is fixed to the inner wall of one side of the first arc shell. A rotating plate is rotatably connected to one side of the support block. A rotating screw is rotatably connected to the bottom of the support block. One end of the rotating screw is engaged with the bottom end of the rotating plate, and the other end of the rotating screw is threaded with an inner wing nut. Connecting plates are fixedly connected to the bottom outer walls of both the first and second arc shells, and the two connecting plates are fixed together by bolts.

[0007] Furthermore, an anti-slip pad is adhered to one side of the support block.

[0008] Furthermore, a sealing frame is bonded to one side of the first arc shell and one side of the second arc shell, with the sealing frame of the first arc shell in contact with the sealing frame of the second arc shell.

[0009] Furthermore, a top seat is fixedly connected to one side of the outer wall of the second arc shell, and a bidirectional threaded rod is rotatably inserted between the inner walls of the two ends of the top seat. Both ends of the bidirectional threaded rod are threaded with sliding blocks.

[0010] Furthermore, one end of the bidirectional threaded rod is fixedly connected to an adjusting handle, and an anti-slip sleeve is fitted onto the outer wall of the adjusting handle.

[0011] Furthermore, a connecting screw is fixedly connected to one side of the sliding block, a pressure plate is sleeved between the two connecting screws, and the connecting screws are slidably connected to the pressure plate. A fastening block is fixedly connected to one end of the connecting screw, and an external wing nut is threaded onto the other end of the connecting screw.

[0012] Furthermore, multiple metal arc rods are embedded within the wall thickness of the first and second arc shells.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The separate design of the first and second arc shells makes it easy to insert the wire harness into the folded tube, and the operation is simple, convenient and quick.

[0015] 2. By passing the wire harness between the bearing block and the rotating plate, then turning the rotating plate to press it onto the wire harness, then turning the rotating screw to engage with the rotating plate, and finally tightening the inner wing nut to fix the rotating plate, the wire harness is secured and thus prevented from coming loose.

[0016] 3. By turning the adjustment handle, the bidirectional threaded rod is rotated, which in turn moves the sliding block, causing the two connecting screws and two fastening blocks to converge in the middle. The two fastening blocks then clamp the vehicle's mounting components, thereby fixing the vehicle-mounted road inspection wiring harness interface protection device through clamping. This allows for the quick installation and fixation of the vehicle-mounted road inspection wiring harness interface protection device. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1-5 A vehicle-mounted road inspection wiring harness interface protection device includes a protection component 1. The protection component 1 includes a first arc shell 101 and a second arc shell 102, which are rotatably connected. Two sets of fixing components 2 are provided inside the first arc shell 101. Each fixing component 2 includes a support block 201, which is fixed to the inner wall of one side of the first arc shell 101. A rotating plate 202 is rotatably connected to one side of the support block 201. A rotating screw 203 is rotatably connected to the bottom of the support block 201. One end of the rotating screw 203 is engaged with the bottom end of the rotating plate 202, and the other end of the rotating screw 203 is threaded with an inner wing nut 204 to connect the wiring harness from the first arc shell 101 and the second arc shell 102. The two ends of 2 are inserted into the first arc shell 101 and the second arc shell 102. Then, the wire harness is passed between the bearing block 201 and the rotating plate 202. Then, the rotating plate 202 is turned to press on the wire harness. Next, the rotating screw 203 is turned to engage with the rotating plate 202. Then, the inner wing nut 204 is tightened to fix the rotating plate 202, thereby fixing the wire harness. The bottom outer walls of the first arc shell 101 and the second arc shell 102 are both welded with connecting plates 3. The two connecting plates 3 are fixed together by bolts to close the first arc shell 101 and the second arc shell 102 together. Then, the two connecting plates 3 are fixed together by bolts, thereby fixing the first arc shell 101 and the second arc shell 102 and thus protecting the wire harness.

[0025] An anti-slip pad 4 is adhered to one side of the support block 201 to prevent the wire harness from falling off the support block 201. Sealing frames 5 are adhered to one side of the first arc shell 101 and one side of the second arc shell 102. The sealing frames 5 of the first arc shell 101 and the second arc shell 102 are in contact, thereby improving the sealing performance between the first arc shell 101 and the second arc shell 102. A top seat 6 is welded to one outer wall of the second arc shell 102. A bidirectional threaded rod 10 is rotatably inserted between the inner walls of both ends of the top seat 6. Sliding blocks 7 are threaded onto both ends of the bidirectional threaded rod 10. An adjusting handle is welded to one end of the bidirectional threaded rod 10, and an anti-slip sleeve is fitted onto the outer wall of the adjusting handle. A connecting screw 8 is welded to one side of the sliding block 7, and a pressure plate 1 is fitted between the two connecting screws 8. 2. The connecting screw 8 is slidably connected to the pressure plate 12. A fastening block 9 is welded to one end of the connecting screw 8. Turning the adjustment handle drives the bidirectional threaded rod 10 to rotate, thereby driving the sliding block 7 to move, which in turn drives the two connecting screws 8 and the two fastening blocks 9 to converge in the middle. Thus, the vehicle's mounting components are clamped by the two fastening blocks 9, thereby fixing the vehicle-mounted road inspection wiring harness interface protection device by clamping. The other end of the connecting screw 8 is threaded with an outer wing nut 11. Tightening the outer wing nut 11 causes the pressure plate 12 to press on the vehicle's mounting components, thereby further fixing the vehicle-mounted road inspection wiring harness interface protection device. Multiple metal arc rods 13 are embedded in the wall thickness of the first arc shell 101 and the second arc shell 102.

[0026] The working principle of this embodiment is as follows: In use, firstly, one end of the connecting screw 8 is passed through the mounting hole of the vehicle. Then, the adjusting handle is turned to drive the bidirectional threaded rod 10 to rotate, thereby driving the sliding block 7 to move. This causes the two connecting screws 8 and the two fastening blocks 9 to converge towards the middle. Thus, the two fastening blocks 9 clamp the mounting component of the vehicle, thereby fixing the vehicle road inspection wiring harness interface protection device by clamping. Next, the outer wing nut 11 is tightened so that the pressure plate 12 presses on the mounting component of the vehicle, thereby further fixing the vehicle road inspection wiring harness interface protection device.

[0027] Then, open the first arc shell 101 outwards. Next, insert the wire harness into the first arc shell 101 and the second arc shell 102 from both ends. Place the wire harness on the anti-slip mat 4. Then, turn the rotating plate 202 to press it onto the wire harness. Next, turn the rotating screw 203 to engage with the rotating plate 202. Then, tighten the inner wing nut 204 to fix the rotating plate 202, thereby fixing the wire harness. Then, close the first arc shell 101 and the second arc shell 102 together. Next, fix the two connecting plates 3 together with bolts, thereby fixing the first arc shell 101 and the second arc shell 102 and protecting the wire harness.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
