Description

Technical Field

[0001] The utility model relates to the technical field of wire harness fixing structures, in particular to a wire harness with a fixing buckle. Background Art

[0002] Wire harness mainly refers to the equipment responsible for providing services to the load source, including control systems, switching devices, etc., which are commonly found in automobiles, home appliances and other equipment. Taking automobiles as an example, automobile wiring harness is the network body of automobile circuits and is the basic facility for realizing various functions of automobiles. With the advancement of science and technology and economic development, people's requirements for the comfort, economy and safety of automobiles are constantly increasing, the types of electronic products in automobiles are increasing, and automobile wiring harnesses are becoming more and more complex.

[0003] When the wire harness is in use, in order to ensure the stability of its connection end and reduce the space occupied by the wire harness, the wire harness is generally arranged and gathered, and then fixed with a fixed buckle or tape or other structure. Although the above fixing method is convenient for loading and unloading, the wire harness lacks a buffer length after being fixed. Since the outer wrapping layer of the wire harness itself has a certain elasticity, after several wire harnesses are gathered, it is easy to cause the curvature of the wire harness to change due to their own elasticity. If the wire harness is completely fixed, the length and the stress generated by the wire harness itself may cause the connection end of the wire harness to detach during the bending change, thereby causing equipment failure. Therefore, after the wire harness is fixed in position, it needs to have a certain activity angle. To this end, the utility model proposes a wire harness with a fixed buckle to achieve improvement on the above problem. Utility Model Content

[0004] The utility model aims to provide a wiring harness with a fixing buckle to solve the problem in the background art that the existing wiring harness fixing structure easily causes the wiring harness connection end to be easily separated during long-term use.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wiring harness with a fixed buckle, comprising a limiting sleeve for fixing the wiring harness; a connecting column is fixed at the lower middle position of the limiting sleeve, and a ball head is fixed at the lower end of the connecting column, and the ball head is rotatably matched with a ball groove shell, the bottom of the ball groove shell is fixed with a bottom plate, and the upper side edge of the bottom plate is integrally extended upward with a protrusion, and the upper side of the bottom plate is fitted with a moving block, and a swing arm is movably provided at the corner between the protrusion and the upper side end of the moving block, a connecting piece is movably provided at the end of the swing arm, and a side plate is fixed to the connecting piece, and a splint is fixed to the lower inner side of the side plate, and a screw is matched with the interior of the moving block, and the screw passes through the protrusion and is connected to a knob.

[0006] Preferably, a limiting stud is provided on the upper portion of the limiting sleeve, and the inner end of the limiting stud conflicts with the limiting arranged inside the limiting sleeve.

[0009] Preferably, a guide rod is fixed to the inner side surface of the ball slot shell, and the guide rod is arranged parallel to the bottom plate.

[0010] Preferably, the guide rod passes through the moving block and the protrusions arranged on the side edges of the bottom plate, and the two guide rods are arranged in parallel.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model fixes the wire harness with a limiting sleeve, and then fixes the buckle as a whole to the external mounting surface under the clamping and fixing of the clamping plate. At the same time, by setting a ball head structure that can be adjusted at multiple angles to fix the limiting sleeve through the connecting column, the limiting sleeve and the wire harness fixed therein can also be used at multiple angles, which has great practical value. In specific use, a suitable mounting surface is selected, the clamping plate is placed on both sides of the mounting surface, and then the knob is rotated, and the knob drives the screw to rotate. Under the driving action of the screw, the moving block gradually moves away from the protrusion. In this process, the angle of the swing arm changes accordingly. Under the supporting action of the swing arm, the connecting piece and the side plate, the clamping plate is tightly fitted to the mounting surface to achieve the position fixing of the device. Then the wire harness is passed through the limiting sleeve and fixed by the limiting stud. At this time, the buckle structure of the wire harness is installed. When the wire harness is in use, the movement of the ball head and the ball groove shell can meet the movement requirements of the wire harness. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the implementation regulations described are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Example

[0019] See also Figure 1-3 , as shown in the figure: This embodiment is a preferred implementation scheme in the present technical scheme, a wiring harness with a fixed buckle, including a limiting sleeve 6 for fixing the wiring harness; a connecting column 5 is fixed to the lower middle position of the limiting sleeve 6, and a ball head 4 is fixed to the lower end of the connecting column 5, and the ball head 4 is rotatably provided with a ball slot shell 2, a bottom plate 1 is fixed to the bottom of the ball slot shell 2, and a protrusion is integrally extended upward at the edge of the upper side surface of the bottom plate 1, and a moving block is fitted on the upper side surface of the bottom plate 1, and a swing arm 10 is movably provided at the corner of the upper side end of the protrusion and the moving block, and a connecting piece 11 is movably provided at the end of the swing arm 10, and a side plate 12 is fixed to the connecting piece 11, and a clamping plate 13 is fixed to the lower inner side of the side plate 12, and a screw rod 9 is provided inside the moving block, and the screw rod 9 passes through the protrusion and is connected to a knob 8;

[0020] It should be noted that: in the wiring harness with a fixed buckle involved in the present application, the wiring harness is mainly fixed by the limit sleeve 6, and then the buckle is fixed to the external mounting surface under the clamping and fixing of the clamp plate 13. At the same time, the limit sleeve 6 is fixed through the connecting column 5 by setting a ball head 4 structure that can be adjusted at multiple angles, so that the limit sleeve 6 and the wiring harness fixed inside it can also be used at multiple angles, which has great practical value. When it is used specifically, a suitable mounting surface is selected, the clamp plate 13 is placed on both sides of the mounting surface, and then the knob 8 is rotated, and the knob 8 drives the screw 9 rotates, and under the driving action of the screw 9, the moving block gradually moves away from the protrusion (the moving block does not rotate with the rotation of the screw 9). In this process, the angle of the swing arm 10 changes accordingly. Under the supporting action of the swing arm 10, the connecting piece 11 and the side plate 12, the clamping plate 13 fits tightly with the installation surface to fix the position of the device. Then the wiring harness passes through the limiting sleeve 6 and is fixed by the limiting stud 7. At this time, the buckle structure of the wiring harness is installed. When the wiring harness is in use, the movement of the ball head 4 and the ball slot shell 2 can meet the movement requirements of the wiring harness.

[0021] Among them Figure 1As shown, a limiting stud 7 is provided on the upper part of the limiting sleeve 6, and the inner end of the limiting stud 7 abuts against the limiting position provided inside the limiting sleeve 6; a fixing member 3 is fixed to the shell side of the ball slot shell 2, and the inner end of the fixing member 3 abuts against and connects with the peripheral side of the ball head 4;

[0022] It should be noted that: there are two limit studs 7. When the limit studs 7 are gradually tightened, the length of the inner end of the limit stud 7 entering the limit sleeve 6 also gradually increases, until the inner end of the limit stud 7 conflicts with the side of the wiring harness built into the limit sleeve 6, thereby fixing the wiring harness inside the limit sleeve 6 to avoid movement of the wiring harness relative to the limit sleeve 6, so that the limit sleeve 6 is suitable for wiring harnesses of different diameters and widths. The fixing member 3 is used to fix the ball head 4 and the ball slot shell 2 to keep them relatively fixed. Conversely, after loosening the fixing member 3, the ball head 4 and the ball slot shell 2 lose their fixed constraints and can move at multiple angles under the action of external force.

[0023] Among them Figure 2 As shown, the inner side of the clamping plate 13 is provided with uniform convex points, and the clamping plate 13 is clamped and fixed on both sides of the outer mounting surface;

[0024] It should be noted that the convex points evenly arranged on the inner side of the clamping plate 13 are used to increase the friction damping between the clamping plate 13 and the outer mounting surface, thereby reducing the possibility of the clamping plate 13 moving after being clamped and fixed with the outer mounting surface.

[0025] Among them Figure 3 As shown, a guide rod 14 is fixed to the inner side of the ball slot shell 2, and the guide rod 14 is arranged parallel to the bottom plate 1; the guide rod 14 passes through the moving block and the protrusion arranged on the edge of the upper side of the bottom plate 1, and the two guide rods 14 are arranged parallel to each other;

[0026] It should be noted that the inner end of the guide rod 14 is fixed to the ball slot shell 2 for installation and fixation of the guide rod 14. To ensure that the linear movement of the moving block is not interfered with, the guide rod 14 needs to be arranged parallel to the base plate 1. The two parallel guide rods 14 can balance the straight movement of the guide rod 14 to avoid position deviation.
