[0027] The implementation of the utility model will be described by specific embodiments below, and those skilled in the art can easily understand other advantages and effects of the utility model from the content disclosed in the specification. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0028] Please refer to Figs. 1 to 3 The utility model provides 1. Wire harness fixing structure, including clamping part, the sliding part of setting in the bottom of clamping part, the sliding groove 1 for embedding the sliding part, the buckle part of setting in the lower end of sliding groove 1, the clamping part includes clamping ring 2, the both sides of clamping ring 2 extend respectively and the elastic clamping arm 4 of the abutment of the clamping arm 3 with the clamping arm 3, the clamping arm 3 and the clamping arm 4 all are inwardly inclined, and the end of the clamping arm 3 and the clamping arm 4 is provided with inner buckle assembly and approaches each other, the buckle part includes two symmetrically arranged buckles, the buckle includes hooking part 5, the abutting part 6 of setting in the upper end of hooking part 5, the abutting part 6 and the sliding groove 1 between the elastic pressing piece for driving two the buckle between approach each other, so as to facilitate the taking out of the buckle.

[0029] When the wire harness needs to be fixed, the wire harness is placed in the clamping ring 2, because the clamping arm 3 and the elastic clamping arm 4 are both inclined inward, and the ends close to each other are provided with an inner buckle assembly, in the process of placing the wire harness into the clamping ring 2, the wire harness will prop open the elastic clamping arm 4, causing it to elastically deform. When the wire harness reaches the appropriate position, the elastic clamping arm 4 restores to its original shape under the action of its own elasticity, and the clamping arm 3 and the elastic clamping arm 4 are buckled to each other through the inner buckle assembly, thereby tightly fixing the wire harness in the clamping ring 2, preventing displacement during use. The sliding part and the sliding groove 1 usually have corresponding shapes and sizes, so that the sliding part can be relatively tightly embedded in the sliding groove 1. During installation, only the sliding part needs to be aligned with the sliding groove 1, and then directly inserted or slid in to complete the preliminary installation, without complex alignment and connection operations, and the disassembly process is simple and fast; the elastic pressing piece design of the buckle part enables the buckle to automatically tighten during installation, achieving rapid fixation, and when disassembling, only a small external force needs to be applied to open the buckle, and the buckle part is taken out, greatly improving the efficiency of installation and maintenance.

[0030] The sliding part includes a sliding block 7 and positioning arms 8 symmetrically arranged on both sides of the sliding block 7. During installation of the wire harness fixing structure, the sliding block 7 of the sliding part is aligned and inserted into the matching sliding groove 1. Because the positioning arms 8 are symmetrically arranged on both sides of the sliding block 7, the positioning arms 8 play a guiding and limiting role, ensuring that the sliding block 7 maintains the correct direction and position during insertion.

[0031] The elastic pressing piece includes elastic pressing blocks 9 symmetrically arranged at both ends of the sliding groove 1, and a connecting rod 10 connected to one end of the elastic pressing block 9 and the abutting portion 6 at the other end. Pressing down the elastic pressing block 9 can drive the connecting rod 10 to push the abutting portion 6, thereby bringing the two buckle parts closer to each other.

[0032] When the buckle needs to be removed, the elastic pressing blocks 9 symmetrically arranged at both ends of the sliding groove 1 are pressed down, and the elastic pressing blocks 9 deform under stress and store elastic potential energy. Since one end of the connecting rod 10 is connected to the elastic pressing block 9 and the other end is connected to the abutting portion 6 of the buckle, the deformation of the elastic pressing block 9 will transmit force through the connecting rod 10, driving the connecting rod 10 to push the abutting portion 6. Under the pushing action of the connecting rod 10, the abutting portions 6 of the two buckle parts are subjected to opposite forces, thereby bringing the two buckle parts closer to each other, causing the buckle to separate from the matching part, and then facilitating the removal of the buckle.

[0033] The inner buckling assembly comprises an inner buckling fixed part 11 arranged at the lower end of the clamping arm 3 and an inner buckling movable part 12 arranged at the upper end of the clamping arm 4. The inner buckling fixed part 11 and the inner buckling movable part 12 are matched with each other, so that the connection between the clamping arm 4 and the clamping arm 3 is more closely and stably connected, which can effectively prevent the clamping arm 4 from being accidentally loosened due to external force during use, ensure that the wire harness is always firmly fixed in the clamping ring 2, reduce the risk of loosening, displacement or even falling of the wire harness due to insecure fixing, and improve the reliability of the wire harness connection.

[0034] The inner buckling fixed part 11 is provided with a first magnetic attraction part, and the inner buckling movable part 12 is provided with a second magnetic attraction part which is attracted to the first magnetic attraction part. The attraction force of the two magnetic attraction parts plays a role of auxiliary positioning and accelerating buckling, so that the clamping arm 4 and the clamping arm 3 can be more closely and stably connected together, thereby better fixing the wire harness. When disassembly is required, a certain external force is applied to make the clamping arm 4 away from the clamping arm 3, overcome the attraction force between the first magnetic attraction part and the second magnetic attraction part, and the inner buckling movable part 12 can be separated from the inner buckling fixed part 11, so as to realize the disassembly of the wire harness fixing structure.

[0035] The clamping ring 2 is circular or rectangular. The circular clamping ring 2 can make the wire harness receive uniform clamping force in the circumferential direction, avoid damage or performance degradation of the wire harness due to uneven force, and the rectangular clamping ring 2 has better space adaptability in some specific installation environment, can more closely arrange and fix multiple wire harnesses, and improve the space utilization rate.

[0036] The above embodiments only exemplarily illustrate the principle and effect of the utility model, and are not used to limit the utility model. All equivalent modifications or changes completed by those skilled in the art without departing from the spirit and technical thought disclosed by the utility model should still be covered by the claims of the utility model.
