[0027] See also Figure 2-3 The adjustable protection structure 2 in this embodiment includes a bellows 21 for bending, an inner tube 22 symmetrically docked on both sides of the bellows 21 to achieve wrapping protection for the automobile wiring harness, side strips 23 symmetrically fixed on both sides of the inner tube 22 for sliding connection, an outer tube 24 movably sleeved on the outside of the inner tube 22 and retractable to adjust the wrapping protection length, a guide strip 25 docked at the upper end of the inner tube 22 for enhancing the smoothness of telescopic movement and subsequent adjustment of the locking effect, and a locking piece 26 provided at the upper end of the outer tube 24 and connected to the inside of the guide strip 25.

[0028] The guide bar 25 further includes locking grooves a equidistantly arranged on the outside in a longitudinal straight line, and the locking grooves a are connected to the bottom of the locking bar 266. Thus, by providing multiple locking grooves a, flexible and diverse telescopic adjustment can be ensured.

[0029] Among them, the inner tube 22 is symmetrically arranged along the front and back of the corrugated tube 21, and the inner diameters of the inner tubes 22 on both sides are smaller than the inner diameters of the first joint 1 and the second joint 3, ensuring that the automobile wiring harness can be stably arranged inside the inner tube 22 and the corrugated tube 21 for efficient wrapping and protection activities; the side strips 23 are symmetrically installed on the left and right sides of the inner tube 22, and the inner tube 22 is slidably connected to the inside of the outer tube 24 through the side strips 23 on both sides, ensuring that the inner tube 22 and the outer tube 24 are stably constructed in a telescopic adjustment state through the side strips 23 on both sides; the guide strip 25 is integrally embedded in the upper end of the outer tube 24, and the shape of the locking groove a opened at the upper end of the guide strip 25 is adapted to the shape of the bottom of the locking strip 266, ensuring that when the outer tube 24 is pulled outward, the locking strip 266 can be intermittently plugged and locked along the locking groove a opened at the upper end of the guide strip 25.

[0030] See also Figure 4-5 The locking member 26 in this embodiment includes a shell 261 that is tightly connected to the upper end of the outer tube 24, a pressure block 262 that is rotatably connected to the right side of the upper end of the shell 261 and can be used to press down and unlock, a connecting piece 263 that is fixedly connected to the lower end of the pressure block 262 and has a horizontal hollow groove inside, a swing arm 264 that is docked inside the connecting piece 263 for swinging, a docking block 265 that is docked at the lower end of the swing arm 264, a locking bar 266 that is tightly connected to the outside of the docking block 265 and vertically plugged into the lower end of the shell 261, a connecting rod 267 that is vertically plugged into the upper end of the locking bar 266 for supporting the guide, a compression spring 268 that is provided on the outside of the connecting rod 267 and abuts against the upper end of the locking bar 266, and the lower end of the locking bar 266 is connected to the inside of the guide bar 25.

[0031] Among them, the swing arm 264 is rotatably connected to the inside of the shell 261, and the lower end of the swing arm 264 is respectively connected to the hollow inside of the connecting piece 263 and the docking block 265. In this way, the connecting piece 263, the swing arm 264 and the docking block 265 can be stably combined to realize convenient transmission locking activities.

[0032] See also Figure 6 The thermal insulation structure 5 in this embodiment includes a first thermal insulation filling layer 51 arranged inside the outer tube 24, and the first thermal insulation filling layer 51 is filled along three sides of the inner side of the outer tube 24, and the size of the first thermal insulation filling layer 51 at the bottom is larger than the size of the first thermal insulation filling layers 51 on the left and right sides, and a second thermal insulation filling layer 52 is filled inside the inner tube 22 to improve the thermal insulation effect.

[0033] Among them, the first thermal insulation filling layer 51 and the second thermal insulation filling layer 52 are both made of polyurethane foam filling. In this way, the outer tube 24 and the inner tube 22 filled with the first thermal insulation filling layer 51 and the second thermal insulation filling layer 52 can provide thermal insulation and protection for the automobile wiring harness, thereby avoiding the high temperature generated inside the automobile and causing accelerated aging of the wiring harness.

[0034] Here’s how it works:

[0035] When the automobile wiring harness protection structure is to be used, the first connector 1 and the second connector 3 can be connected to the front and rear sides of the adjustable protection structure 2 to realize the overall composition of the protection structure. At this time, the automobile wiring harness can be inserted into the first connector 1, the adjustable protection structure 2 and the second connector 3 to wrap the automobile wiring harness as a whole for protection, thereby avoiding the exposure of the automobile wiring harness and reducing the problem of high temperature generated by the operation of the automobile affecting the wiring harness.

[0036] The bellows 21 provided inside the adjustable protective structure 2 can provide bending adaptability when the automobile wiring harness needs to be bent, thereby ensuring the stability of the automobile wiring harness connection. At the same time, the inner tube 22 connected to the front and rear sides of the bellows 21 can cooperate with the outer tube 24 sleeved on the outside to achieve wrapping protection for the entire wiring harness, thereby avoiding contact wear between the automobile wiring harness and the interior of the vehicle body, thereby extending the service life of the automobile wiring harness.

[0037] Furthermore, when it is necessary to wrap and protect wire harnesses of different lengths, the pressing block 262 connected to the upper end of the shell 261 can be pressed down to push the internally connected swing arm 264 downward through the connecting piece 263 connected at the bottom. In this way, the docking block 265 docked at the lower end of the swing arm 264 will realize the upward movement of the entire locking bar 266 through the swing of the swing arm 264. In this way, the locking bar 266 will be guided by the upper end plug-in connecting rod 267 to achieve stable upward movement and squeeze the compression spring 268 against the upper end. When the locking bar 266 moves into the interior of the shell 261, the plug-in lock of the lock groove a opened between the bottom of the locking bar 266 and the upper end of the guide bar 25 can be released. As a result, the user can push the outer tube 24 as a whole to make the outer tube 24 cooperate with the left and right sides of the inner tube 22. The side strips 23 and the guide strips 25 provided at the upper end are guided to move outward for adjustment. In this way, the outward-moved outer tube 24 will lengthen the use length of the wire harness protection structure, so that it can meet the requirements of the wrapping protection of longer wire harnesses. Moreover, after the outward pulling adjustment of the outer tube 24 is completed, the pressure block 262 can be loosened to make the compression spring 268 compressed at the upper end of the locking strip 266 rebound. In this way, the locking strip 266 will automatically move downward to reinsert into the locking groove a inside the upper end of the guide strip 25 for plugging and locking. At the same time, as the locking strip 266 moves downward for plugging and locking, the docking block 265 will drive the swing arm 264 to automatically push up the connecting piece 263 and the pressure block 262 on the right side of the swing arm 264, thereby achieving automatic reset transmission, thereby achieving flexible adjustment of the use length of the wire harness protection structure and convenient locking or unlocking activities.

[0038] At the same time, the second thermal insulation filling layer 52 and the first thermal insulation filling layer 51 provided inside the inner tube 22 and the outer tube 24 can make the inner tube 22 and the outer tube 24 have certain thermal insulation properties to block the high temperature generated by the operation of the car, avoid high temperature from accelerating the aging rate of the wire harness, and improve the overall service life of the wire harness.
