Multiple through holes 6 are opened on the surfaces of the upper shell 1 and the lower shell 2. Multiple fixing holes 7 are opened on the surfaces of the connecting plates 5. Multiple fixing plates 8 are welded and installed on one side of the top of the upper shell 1 and the bottom of the lower shell 2. The fixing pins 9 are inserted and installed on both sides of the fixing plates 8. The cross plates 10 are installed at one end of the fixing pins 9. The first springs 11 are sleeved and installed outside the fixing pins 9. Multiple limiting blocks 12 are respectively embedded and installed in the upper shell 1 and the lower shell 2. The threaded rods 13 are inserted and installed at both ends of the limiting blocks 12. The clamping fixtures 14 are rotatably installed at one end of the threaded rods 13. The connecting plates 5 and the through holes 6 are arranged correspondingly. The fixing pins 9 and the fixing holes 7 are arranged correspondingly. The first springs 11 are located between the fixing plates 8 and the cross plates 10. The threaded rods 13 and the limiting blocks 12 are screwed together by threads. The cross section of the clamping fixture 14 is in an arc structure. An insulating soft protective layer is provided on the inner wall of the clamping fixture 14. When the user pulls the cross plate 10 outwards, the movement of the cross plate 10 causes the first spring 11 to stretch and the fixing pin 9 to move. Then, the upper shell 1 and the lower shell 2 are sleeved outside the automotive wire harness. At this time, the connecting plate 5 is inserted into the through hole 6. When the cross plate 10 is released, under the elastic force of the first spring 11, the fixing pin 9 is inserted into the fixing frame, and the combination connection of the upper shell 1 and the lower shell 2 can be completed, realizing the protection of the automotive wire harness, facilitating the user to quickly and conveniently protect the automotive wire harness. The user can also rotate the threaded rod 13. Under the setting of the limiting block 12, the rotation of the threaded rod 13 causes the clamping fixture 14 to move, ensuring the fit of the clamping fixture 14 with the automotive wire harness, avoiding the situation of shell offset, realizing a good protection effect. At the same time, the fit of the clamping fixture 14 with the automotive wire harness can prevent the automotive wire harness from being bent.

[0024] As Figure 1 shown, the upper shell 1 and the lower shell 2 are arranged correspondingly. The overall thickness of the lower shell 2 is greater than that of the upper shell 1. With the settings of the upper shell 1 and the lower shell 2, the automotive wire harness can be protected.

[0025] As Figure 1 and Figure 4As shown in the figure, the limiting component 4 includes multiple groups of limiting plates 15, multiple groups of limiting rods 16, a fixing frame 17, a limiting roller 18 and a second spring 19. The multiple groups of limiting plates 15 are respectively installed on the side walls of the upper shell 1 and the lower shell 2 through bolts. The multiple groups of limiting rods 16 are installed through both ends of the limiting plates 15. The fixing frame 17 is installed at the top of the limiting rods 16. The limiting roller 18 is rotatably installed on the inner wall of the fixing frame 17. The second spring 19 is sleeved on the outside of the limiting rods 16. The cross section of the fixing frame 17 is in a U-shaped structure. The second spring 19 is located between the fixing frame 17 and the limiting plates 15. With the arrangement of the limiting plates 15 and the fixing frame 17, the limiting roller 18 can be installed and fixed. The limiting roller 18 can be used to protect the automotive wire harness entering and exiting both ends of the upper shell 1 and the lower shell 2, avoiding abrasion between the automotive wire harness and the fastening member 14, the upper shell 1 or the lower shell 2, and achieving a good protection effect. With the arrangement of the limiting rods 16 and the second spring 19, the automotive wire harnesses of different sizes can be limited and protected.

[0026] The utility model provides an automotive wire harness protection shell, and the specific working principle is as follows:

[0027] When using this automotive wire harness protection shell, by providing a connection component 3, the user pulls the cross plate 10 outwards. The movement of the cross plate 10 causes the first spring 11 to stretch and the fixing pin 9 to move. Then, the upper shell 1 and the lower shell 2 are sleeved outside the automotive wire harness. At this time, the connecting plate 5 is inserted into the through hole 6. After releasing the cross plate 10, under the rebounding force of the first spring 11, the fixing pin 9 is inserted into the fixing frame, and the merging connection of the upper shell 1 and the lower shell 2 can be completed, realizing the protection of the automotive wire harness, facilitating the user to quickly and conveniently protect the automotive wire harness. The user can also rotate the threaded rod 13. With the arrangement of the limiting block 12, the rotation of the threaded rod 13 causes the fastening member 14 to move, ensuring the fit between the fastening member 14 and the automotive wire harness, avoiding the situation of shell offset, and achieving a good protection effect. At the same time, the fit between the fastening member 14 and the automotive wire harness can prevent the automotive wire harness from being bent. By providing a limiting component 4, with the arrangement of the limiting plates 15 and the fixing frame 17, the limiting roller 18 can be installed and fixed. The limiting roller 18 can be used to protect the automotive wire harness entering and exiting both ends of the upper shell 1 and the lower shell 2, avoiding abrasion between the automotive wire harness and the fastening member 14, the upper shell 1 or the lower shell 2, and achieving a good protection effect. With the arrangement of the limiting rods 16 and the second spring 19, the automotive wire harnesses of different sizes can be limited and protected.
