Abstract

The utility model belongs to the field of pipeline arrangement, and particularly relates to a pipeline fixing clamp comprising a groove, with an elastic opening, used for accommodating pipelines. The size of the opening is smaller than the groove diameter naturally, and the groove wall, far from the groove opening, of lower portion of a clamp body is connected with convex pins inserted in mounting holes. The pipeline fixing clamp has the advantages that on the basis of positioning and vibration resistant effects, the pipeline fixing clamp is simple in structure and easy to assemble, the pipeline fixing clamp allows assembly of pipelines with various diameters by changing rubber pads of different specifications, and cost is saved.

Description

Retaining clip for pipelines

Technical field

The utility model belongs to pipeline and arranges field, and concrete is a kind of retaining clip for pipelines.

Background technique

Now, relating to very many-sided pipeline such as automotive field, building field all needs to fix, and retaining clip for pipelines is just obtaining very large application aspect fixing at existing pipeline.In existing Duct fixing clamp, be all much complicated structure, it is convenient not to install.As patent CN200810186620 name is called the patent of air-conditioning pipeline pipe clamp, its main structure is to utilize a closed annular to be embedded in rubber strip clamping body, closed loop configuration is that the structure that two barb-like are set at plastic strip two ends just becomes closed ring structure by the bayonet socket of two barbs actually, and the mounting structure of pipe clamp body adopts a waist shaped hole and kidney-shaped post to fix, kidney-shaped master's external diameter is slightly larger than the internal diameter of waist-shaped hole, inserts the tension force forming in waist-shaped hole realize the fixing of pipe clamp body by kidney-shaped post.This technology can solve fixation problem shockproof and to a certain extent, but his shortcoming is to realize three steps of the fixing needs of pipeline: the loop configuration of open closed, put into pipeline, closed barb again, also need two steps to realize to the fixing of pipe clamp body: the kidney-shaped post of body mounting portion to be inserted in stamping holes, then insert kidney-shaped post.The shortcoming of this model utility is that the inadequate simple and stable of operation is inadequate, and Duct fixing clamp is wasted time and energy and same pipe clamp can only be used on a kind of pipeline of caliber, will shine into like this unfavorable factors such as cost of production increases.

Model utility content

The purpose of this utility model is solve the complicated operation problem of Duct fixing clamp, assembling pipeline and solve the problem that clamps the pipeline of joining different caliber models with an arm with a kind of pipe clamp simple in structure.

For achieving the above object, the technological scheme providing is: a kind of retaining clip for pipelines, comprise the draw-in groove of the elastic opening tubulose that holds pipeline, notch under draw-in groove nature is less than himself groove footpath, on cell wall away from its notch place on draw-in groove, be connected with and be the pin that convex is arranged, pin is inserted in mounting hole.

The technology providing by the utility model can be for the very simple pipe fixing clamp of structure, and has played and located shockproof good result, it is simple in structure, and assembling easily, and has realized a fixing clamp and can assemble the pipeline of multiple caliber, provides cost savings.

Brief description of the drawings

Fig. 1 is the axonometric drawing of retaining clip for pipelines;

Fig. 2 is the plan view of retaining clip for pipelines;

Fig. 3 is the A-A sectional view of Fig. 2;

Fig. 4 is the zoomed-in view of B part in Fig. 2.

Specific implementation method

In conjunction with Fig. 1 to Fig. 4, the utility model is understood in detail:

As shown in Figure 1, 2, a kind of retaining clip for pipelines, comprises the draw-in groove 10 of the elastic opening tubulose that holds pipeline, notch under draw-in groove 10 natures is less than himself groove footpath, and after pipeline is planted wherein, notch is little, retaining clip for pipelines has an effect packing tightly to pipeline, prevents skidding off of pipeline; On cell wall away from its notch place on draw-in groove 10, be connected with and be the pin 20 that convex is arranged, pin 20 is inserted in mounting hole, realizes fixing retaining clip for pipelines.

Further, for realizing better conception, draw-in groove 10 is provided with trumpet-shaped cushion 30 with pin 20 junctions, and cushion 30 is realized with the effective of the mounting hole space of a whole page and being fixed; The cross section overall U-shaped of draw-in groove 10, the edge side of its notch arranges to the flange 11 extending in vallecular cavity, the plate face direction of flange 11 is pointed to the center of circle direction of draw-in groove 10 bottom circular contours, it is exactly effectively fixing pipeline that flange points to reality, the overhang edge place of described flange 11 arranges press strip 12, press strip 12 is L or T shape with the cross section of flange 11 junctions, and press strip 12 is tangent with the circle that draw-in groove 10 bottom circular contours form, and press strip 12 just has a kind of pressuring action to the outer wall of pipeline; As shown in Figure 2, draw-in groove bottom is the card chamber 13 of a semicircular in shape, 13 li, chamber of card card has rubber pad 50, the joint of the top in described card chamber 13 and the straight-arm portion of draw-in groove 10 is provided with convex tendon 14, in the card chamber 13 of rubber pad 50 between two convex tendons 14, by the replacing to different-thickness rubber pad, the groove footpath of draw-in groove 10 will change like this, so just can grip effect to the pipeline of different tube diameters certain realization.

Closer, as shown in Fig. 1 or 4,20 times tops of pin are provided with the take the shape of the letter U elastomer 40 of shape of cross section, vallecular cavity and the pin lower surface of elastomer U-groove bevel bottom are fixed, two sides of elastomer 40 overhang to the upper top of pin 20, and the top of described elastomer 40 projecting ends arranges stepped ladder platform structure 41, and ladder platform structure 41 realizes the lower surface Elastic Contact with mounting hole, so just there is a pretightening force, reach a kind of fastening effect.
