Description

Technical Field

[0001] This utility model relates to the technical field of cable harness installation, specifically to a cable harness protection structure. Background Technology

[0002] Cable harnesses are components that integrate multiple wires or cables through binding, sheathing, or braiding. They are used to efficiently transmit power or signals, improve system reliability, and increase space utilization.

[0003] During installation, especially at cable protection duct openings, the cable is prone to friction with the duct opening, easily causing wear on the cable sheath. Therefore, appropriate protective mechanisms are needed. One example is a cable harness protection device with patent publication number CN222262047U, which uses three sets of clamping components to hold the wall of the protective tube. When dragging the cable into the protective tube, the cable simply passes through the inside of the second ring. As the cable is dragged, it drives the contacting rollers to rotate, facilitating cable dragging and preventing… This design avoids wear caused by contact between the cable and the conduit opening. Each set of support rods can be extended and retracted to accommodate conduits of different diameters. When the cable is dragged on the ground, each set of support rods can be rotated to horizontally support the first ring on the ground using the three sets of support rods. Then, the second ring can be rotated 90 degrees. To prevent the cable from being dragged on the ground and worn, the cable can pass through the inside of the second ring. This avoids direct contact between the cable and the ground, and the dragging of the cable will cause the contacting rollers to rotate, making it easier to drag the cable.

[0004] However, its structure is complex, its cost is high, its loading and unloading are inconvenient, and its practicality is insufficient. Utility Model Content

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a cable harness protection structure with a threaded fastening structure and a roller structure that allows for active contact of the cable, preventing wear at the pipe opening. This structure is simpler and more practical.

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a cable harness protection structure, including a cable harness conduit, and further including a sleeve, a tightening screw sleeve, a tightening screw rod, a tightening handle, a connecting frame, a ring frame, a constraint frame, a rotating shaft, and a rubber wheel. Three sets of tightening screw sleeves are evenly connected circumferentially in the middle of the sleeve. The inner wall of each set of tightening screw sleeves is screwed to the outer wall of a set of tightening screw rods. The outer side of each set of tightening screw rods is connected to the middle of the inner side of a set of tightening handles. The outer side of the sleeve is connected to the rear side of two sets of connecting frames via an installation structure. The front interior of the two sets of connecting frames is connected to the left and right sides of the ring frame. Multiple pairs of constraint frames are evenly connected circumferentially in the inner side of the ring frame. Each pair of constraint frames has a rotating shaft rotatably installed inside, and the outer wall of the rotating shaft is connected to the inner wall of the rubber wheel.

[0007] Preferably, the installation structure includes an installation groove, a through groove, an inner groove, bolts, and nuts. The left and right sides of the cable harness conduit are respectively connected to the inner ends of a set of installation grooves. Each set of installation grooves has a through groove at the front and an inner groove at the rear of each set of connecting frames. The connecting frame and the installation groove on the same side are detachably inserted. The bolts pass through the through groove and the inner groove simultaneously and are screwed on the protruding side by nuts.

[0008] Preferably, it also includes anti-loosening washers, and each set of anti-loosening washers is provided on the outer side of the mounting part of each bolt and nut.

[0009] Preferably, it also includes contact pads, with a set of contact pads connected to the inner side of each set of tightening screws.

[0011] Preferably, it also includes an opening slot, wherein one side of the ring frame is provided with an opening slot located outside a pair of constraint frames.

[0012] (III) Beneficial Effects Compared with the prior art, this utility model provides a cable harness protection structure, which has the following beneficial effects: The sleeve is fitted onto the outside of the cable harness conduit. Then, multiple sets of tightening handles are turned to rotate the tightening screw. The tightening screw, through its screw engagement with the tightening sleeve, acts inward to tighten the cable harness conduit at that position, thus fixing the sleeve relative to the cable harness conduit. The mounting structure then connects to the connecting frame, fixing the ring frame at the inner opening of the cable harness conduit. The cable can rotate through multiple restraint shafts within the ring frame, and its movement is further constrained by the rolling of rubber wheels, thus preventing cable wear at the conduit opening. The screw-fit tightening structure, combined with the roller structure, allows for proper cable contact, preventing wear at the conduit opening. The structure is simpler and more practical.

The outer side of each set of tightening screws 4 is connected to the middle inner side of a set of tightening handles 5. The outer side of the sleeve 2 is connected to the rear side of two sets of connecting frames 6 via an installation structure. The front interior of the two sets of connecting frames 6 is connected to the left and right sides of the ring frame 7. Multiple pairs of constraint frames 8 are evenly connected circumferentially inside the ring frame 7. Each component is equipped with a set of rotating shafts 9, the outer wall of which is connected to the inner wall of the rubber wheel 10. The sleeve 2 is placed on the outside of the cable harness conduit 1, and then multiple sets of tightening handles 5 are turned to rotate the tightening screw 4. The tightening screw 4 is screwed into the tightening sleeve 3 and acts inward to tighten the cable harness conduit 1 at that position, thereby fixing the sleeve 2 relative to the cable harness conduit 1. Then, the connecting frame 6 is connected to the installation structure, so that the ring frame 7 is fixed at the inner opening of the cable harness conduit 1. The cable can be constrained by the rotating shaft 9 within the ring frame 7 and its movement is constrained by the rolling of the rubber wheel 10, thereby avoiding wear of the cable at the opening of the cable harness conduit 1.

[0017] The installation structure includes an installation groove 11, a through groove 12, an inner groove 13, bolts 14, and nuts 15. The left and right sides of the cable harness conduit 1 are respectively connected to the inner end of a set of installation grooves 11. Each set of installation grooves 11 has a through groove 12 at the front and a set of inner grooves 13 at the rear of each set of connecting brackets 6. The connecting brackets 6 and the installation grooves 11 on the same side are detachably inserted. The bolts 14 pass through the through grooves 12 and the inner grooves 13 simultaneously and are screwed on the protruding side by nuts 15. The two sets of connecting brackets 6 of the ring frame 7 are inserted into the corresponding installation grooves 11, so that the inner grooves 13 correspond to the through grooves 12. Then, the bolts 14 can pass through the through grooves 12 and the inner grooves 13 simultaneously and are screwed on the protruding side by nuts 15, thereby connecting and fixing the anti-loosening washers 16 relative to the installation grooves 11, which is convenient for installation and removal.

[0018] It also includes anti-loosening washers 16. Each set of anti-loosening washers 16 is provided on the outer side of the mounting part of each bolt 14 and nut 15.
