Detailed Description

Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

Referring to fig. 1 to 3, the utility model provides a pipeline fixing clip, include: the pipe clamp comprises a pipe clamp body 21, wherein at least two through holes 212 arranged side by side are formed in the pipe clamp body 21, and the through holes 212 penetrate through a first end face and a second end face which are oppositely arranged on the pipe clamp body 21 and a third end face which is adjacent to the first end face and the second end face and is arranged on the pipe clamp body 21; the rubber bushing 14 of a through cavity for the pipeline 11 to be fixed to pass through is arranged along the axial direction of the through hole 212, and one rubber bushing 14 is arranged in each through hole 212; the buckling structures 211 are arranged corresponding to the at least two through holes 212 one to one, one end of each buckling structure 211 is rotatably arranged on the pipe clamp body 21, and the pipe clamp body 21 is provided with flanging barbs 131 buckled with the other end of each buckling structure 211; when the other end of the snap-fit structure 211 is snapped with the burring barb 131, the rubber bushing 14 is locked in the through hole 212. The flanging barb 131 and the pipe clamp body 21 are integrally formed by injection molding.

As shown in fig. 1, the first end surface is a front end surface in fig. 1, the second end surface is a rear end surface in fig. 1, and the third end surface is an upper end surface in fig. 1. That is, the through hole 212 is a hole penetrating three end surfaces of the pipe clamp body 1. Thus, when the rubber bush 14 is fitted into the through hole 212, the rubber bush 14 may fall out of the through hole without closing the portion of the through hole 212 communicating with the third end surface. Therefore, the fastening structure 211 is mainly used to seal the opening of the through hole 212 on the third end surface, so that after the pipeline 11 to be fixed is installed in the rubber bushing 14, the rubber bushing 14 and the pipeline 11 to be fixed cannot fall off, and the fixing effect of the pipeline 11 to be fixed is ensured.

Specifically, as shown in fig. 1, a groove 141 is formed on an outer surface of the rubber bushing 14, and a first barb 2121 made of a flexible material and matching with the groove 141 is protruded on an inner wall of the through hole 212. Wherein, this first barb 2121 mainly adopts flexible material such as plastics to make, and this first barb 2121 is for setting up and having the protruding piece of certain inclination in protruding on the pore wall of through-hole 212, and in the in-process of inserting rubber bush 14 into this through-hole 212 from this pipe strap body 1 opening on the third terminal surface, first barb 2121 is pushed down under the downward thrust of rubber bush 14, and when the recess 141 that is in rubber bush 14 removed to the position department relative with this first barb 2121, first barb 2121 entered into recess 141, forms the lock. However, since the first barbs 2121 are made of a flexible material, the fastening strength between the first barbs 2121 and the grooves 141 is not high, and there is a possibility that the fastening between the first barbs 2121 and the grooves 141 is lost due to the bumping of the vehicle during the driving of the vehicle, which may cause the rubber bushing 14 to be detached from the through hole 212. Therefore, in the present application, the snap structure 211 is provided. As shown in fig. 2, one end of the fastening structure 211 is hinged to the pipe clamp body 21 by a hinge, and the other end of the fastening structure 211 and the pipe clamp body 21 are respectively provided with a flanging barb 131 for forming a snap-fit relationship, so that the rubber bushing 14 is fastened in the through hole 212 by the snap-fit of the flanging barb 131 on the fastening structure 211 and the flanging barb 131 on the pipe clamp body 21. Meanwhile, as can be seen from fig. 2, a first barb 2121 is also protrudingly provided on the snap-fit structure 211, and the first barb 2121 can be positioned to match with the groove 141 on the rubber bushing 14.

The pipeline clamping groove 15 is designed at the lower part of the buckling structure 211 so as to be convenient for matching and assembling other pipelines with different pipe diameters, and the specific size of the pipeline clamping groove 15 is determined according to the matched pipeline size. Similarly, the second barb 151 is made of a material having elasticity, such as plastic. The difference from the first barb 2121 is that the second barb 151 has a length much greater than the first barb 2121, and the chamfer formed by the second barb 151 is greater than the chamfer formed by the first barb 2121. Thus, after the pipeline is clamped in the pipeline clamping groove 15, the pipeline is blocked by the chamfer formed by the second barb 151, and the pipeline is fixed.

In this embodiment, the fastening structures 211 and the through holes 212 are arranged in a one-to-one correspondence manner, that is, after one fastening structure 211 and the corresponding flanging barb 131 are fastened, only the rubber bushing 14 and the pipeline 11 to be fixed in the through hole 212 corresponding to the fastening structure 211 are fixed, and the assembly of the rubber bushing 14 and the pipeline 11 to be fixed in the other through holes 212 is not affected.

During actual assembly, fix each pipe strap body 21 in automobile body floor 12 through projection welding screw 23 earlier, buckling structure 211 does not buckle with turn-ups barb 131 this moment, then places single pipeline 11 of treating to fix in rubber bush 14 that each pipeline fixing clip was with one side according to arranging the requirement, and the position of laying is after appropriate fixed with buckling structure 211 lock in proper order, and single pipeline assembly targets in place promptly. Because the buckling structure on the other side is not buckled when the single pipeline 11 to be fixed is assembled, the single oil pipe 11 can be independently assembled in place, and the normal installation of other pipelines is not influenced.

Preferably, the pipeline 11 to be fixed is in interference fit with the rubber bushing 14, so that during installation, the pipeline 11 to be fixed needs to be manually pressed into the through hole 212. And the rubber bushing 14 is designed in the matching hole to be tightly pressed with the pipeline 11 in an interference fit manner, so that the vibration reduction and fixing effects are achieved, the pipeline 11 to be fixed is prevented from axially moving, and the problem of interference of the pipeline 11 to be fixed with other hand parts caused by axial movement can be prevented.

In the embodiment, by adjusting the buckling structure of the pipeline fixing clamp, the unilateral buckling form is adjusted to the bilateral buckling form, so that when a plurality of pipelines 11 to be fixed side by side are installed on the same pipeline fixing clamp, the assembly of a single pipeline 11 to be fixed is not influenced by other pipelines and can be separately connected and fixed with the pipeline fixing clamp; the workman need not to consider because the unilateral lock pipeline that brings side by side fixes the problem simultaneously at the assembly process, also can reduce the rotation that the pipeline probably exists in the assembly process, risk such as buckling deformation.
