Description

Technical Field

[0001] The utility model belongs to the technical field of protective covers for wire harnesses, and in particular relates to a protective cover for wire harnesses. Background Art

[0002] The wiring harness is the overall set of service equipment that provides services to a certain group of load sources, such as relay lines, switching devices, control systems, etc.

[0003] For example, a Chinese patent with a publication number of CN216649119U discloses a protective sleeve for automotive wiring harnesses, including a tube body, one end of which is formed with an arc block, and the other end is formed with a protrusion outwardly, the protrusion has an arc groove adapted to the arc block, and the tube body is provided with a stopper to prevent the arc block from separating from the arc groove. In this application, when two tube bodies are connected, the arc block and the arc groove are used for the initial positioning of the two tube bodies. Under the action of the spring, the moving ring drives the positioning block to be clamped between two adjacent protrusions, which can avoid the separation of the arc block and the arc groove, and complete the installation of the two tube bodies. This detachable design can facilitate the staff to adjust the length of the protective sleeve.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when used, such as: when the device is extended, it is not easy to adjust the angle between the two tubes, and the sealing between the two tubes is poor. When washing the car, some water may enter from the connection between the two tubes, which may cause danger. Moreover, the device is not easy to fix to the car cabin, which may cause the tube to shake when the car is running, and the wire harness inside the tube will also shake, which may cause the surface of the wire harness to be damaged. In view of this, we propose a protective cover for wire harness. Utility Model Content

[0006] The utility model aims to provide a protective cover for a wire harness to solve the problems raised in the above background technology.

[0007] In view of this, the utility model provides a protective cover for a wire harness, comprising:

[0008] A protective sleeve, one end of the protective sleeve is fixedly installed with a bellows, one end of the bellows is fixedly installed with a connecting block, the connecting block is connected to the bellows and the protective sleeve, one side of the connecting block and at the four corners are rotatably installed with threaded rods, one side of the connecting block is fixedly installed with a sealing ring 1, the bottom of the protective sleeve is symmetrically provided with sliding grooves, a two-way threaded rod is rotatably installed in the sliding groove, one end of the two-way threaded rod passes through one side of the sliding groove and extends to the outside, two clamping plates are slidably installed in the sliding groove and on the two-way threaded rod, the other end of the protective sleeve and near the four corners are provided with threaded holes, and the other end of the protective sleeve is fixedly installed with a sealing ring 2;

Under the action of the threads, the two clamping plates on the bidirectional threaded rods will approach each other until the two clamping plates clamp the fixing rod. Under the action of the rubber pad, it is ensured that the two clamping plates can clamp more stably, so that the protective cover is fixed;

[0011] When the wiring harness is longer and a protective cover needs to be added, the staff will align the four threaded rods on the added connecting block with the four threaded holes on the installed protective cover one by one, and then make the two driving components in the added connecting block drive the corresponding threaded rods to rotate. Under the action of the threads, the threaded rods will rotate and move in the threaded holes.

[0013] Two power chambers, the two power chambers are symmetrically opened in the connecting block, a worm is rotatably installed in the power chamber and at a position away from the sealing ring, two worm wheels are rotatably installed in the power chamber and at a position close to the sealing ring, the worm wheel is meshed with the worm, one end of the worm wheel passes through one side of the power chamber and is coaxially connected to the corresponding threaded rod, and one end of the worm passes through one side of the connecting block and extends to the outside.

[0014] In this technical solution, the handle on the worm in the added connecting block is rotated to drive the two worms to rotate respectively. Under the action of meshing, the worm will drive the worm wheel to rotate, and then the worm wheel will drive the threaded rod to rotate.

[0015] In the above technical solution, further, one end of the worm is rotatably connected to the connecting block.

[0016] In this technical solution, it is ensured that one end of the worm can rotate on the connecting block.
