Description

Technical Field

[0001] The utility model relates to the technical field of computer wire harness fixing, in particular to an anti-collision and anti-dropping structure for a computer host. Background Art

[0002] Publication (Announcement) No.: CN218603076U, a computer power harness anti-drop buckle, which uses a clamping function to fix multiple sets of harnesses connected to the host. However, in fact, there are various types of harnesses connected to the computer host, including power cords and various data cables, and the diameters are mostly different. Therefore, it is difficult to ensure that a unified clamping force can bring sufficient clamping force to each harness. Furthermore, the harnesses connected to the host, such as mouse cables, keyboard cables, network cables, power cables, etc., have different lengths. The excessively long parts are often dragged directly on the ground and are very easy to be kicked and pulled off by mistake. Therefore, a computer host anti-collision and anti-drop structure is needed, which has good applicability and can simultaneously complete the winding of harnesses of various lengths. Utility Model Content

[0003] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides an anti-collision and anti-dropping structure for a computer host, which is achieved by the following specific technical means: it includes a base frame, a hugging and fixing mechanism is arranged on the front side of the base frame, the hugging and fixing mechanism is used to fix the base frame on the host chassis, and a plurality of groups of wire harness anti-dropping and tightening mechanisms are arranged in parallel on the rear side of the base frame, the wire harness anti-dropping and tightening mechanism includes a fixed cover, a cover body and a winding rack, the fixed cover is arranged on the base frame, and the cover body is opened and closed on the fixed cover port. At the same time, a power shaft is rotated and penetrated in the fixed cover, and the winding rack is arranged at the inner end of the power shaft. Two groups of groove holes are opened opposite to the side wall of the fixed cover. When in use, the wire harness is put into the groove hole on the rear side, then bypasses the winding rack and is pulled out from the front groove hole. The winding rack is driven by the rotation of the power shaft to rotate and the wire harness is rolled up and tightened, thereby shortening the overall length and avoiding the excessively long part from being dragged on the ground. At this time, the cover body is closed.

[0004] Preferred technical solution 1: The winding frame includes a horizontal plate arranged in the middle on the power shaft and fixed rods arranged at both ends of the horizontal plate. After the wire harness enters the fixed cover, it crosses and bypasses the two sets of fixed rods.

[0005] Preferred technical solution two: a boss is provided at the top of the fixed cover, a connecting shaft is rotatably and slidably penetrated on the boss, the cover body is provided on the connecting shaft, and a spring is connected between the enlarged end of the connecting shaft away from the cover body and the boss. The setting of the spring enables the cover plate to close the fixed cover port and press tightly on the end face of the fixed rod to prevent the wiring harness from rotating and loosening after tightening.

[0006] Preferred technical solution three: a convex tooth 1 is arranged on the end face of the fixing rod, and a convex tooth 2 which can mesh with the convex tooth 1 is arranged in a ring-shaped manner on the inner side of the cover body. When the cover is closed, the convex tooth 1 on the fixing rod meshes with the convex tooth 2 on the cover at the corresponding position to avoid accidental rotation of the toggle wheel.

[0007] Preferred technical solution four: The embracing and fixing mechanism includes a horizontal handle 1, a horizontal handle 2 and a double-headed screw. A horizontal through hole is opened on the front side of the base frame. The double-headed screw is rotatably arranged in the horizontal through hole. The horizontal handle 1 and the horizontal handle 2 are sleeved on the two ends of the double-headed screw through threaded holes and extend out from the two ends of the horizontal through hole away from each other. The outer ends of the horizontal handle 1 and the horizontal handle 2 are provided with splints.

[0008] The above structure enables this solution to have the following beneficial effects:

[0009] 1. Use multiple sets of hugging and fixing mechanisms to wind and tighten the overlong parts of various wire harnesses connected to the computer host to prevent the overlong parts from dragging on the ground, thereby achieving the technical effect of anti-collision and anti-dropping;

[0010] 2. Through the structural setting between the cover body and the fixing rod, the posture of the winding frame is fixed after the cover body is closed, and the wire harness will not fall off;

[0011] 3. Abandon the method of clamping and fixing the wire harness, and effectively tighten wire harnesses of various thicknesses and shapes, which is more practical. BRIEF DESCRIPTION OF THE DRAWINGS
