Abstract
The utility model discloses a pipeline joint clamping piece. The pipeline joint clamping piece comprises a ring-shaped clamping band, wherein a convex rib is arranged on the inner wall of the clamping band; the length of the clamping band is greater than the circumference of the ring, that is, part of the clamping band is overlapped; clamping columns are arranged on the outer sides of the two ends of the clamping band, and are provided with screw holes respectively; the two screw holes are connected to each other through a screw bolt. The pipeline joint clamping piece has the advantages that the air tightness of a pipeline connector is ensured, so that water leakage at the pipeline connector, which is caused by high pressure in a pipeline can be avoided; the pipeline joint clamping piece is convenient to install, high in bearing resistance, low in cost, and good in soft band mounting effect, as well as good in elasticity and high in tension by utilizing the steel band (namely the clamping band).
Description
Technical field
The utility model relates to a kind of pipe coupling, and specifically a kind of pipe coupling fastener for joint, PE drip irrigation pipe road junction, belong to the pipe coupling field.
Background technique
Joint, drip irrigation pipe road junction need to be carried out affixed, and existing fastener is all generally to use iron wire, or steel wire reinforces at pipeline outer wall, and cumbersome when this method is used, efficiency is low, and compressive resistance is little, and sealing effect is poor, and working life is short.
The model utility content
In order to address the above problem, the utility model has designed a kind of pipe coupling fastener, has guaranteed the sealing of pipe joint, can not cause the pipe joint place leak or throw off greatly because of the pressure in pipeline.
The technical solution of the utility model is:
A kind of pipe coupling fastener, comprise circular clamping band, the inwall of described clamping band is provided with convex tendon, the length of described clamping band is greater than the girth of described annulus, be that a described clamping band part is overlapping, the outside, two ends of described clamping band is respectively equipped with clamping column, and described clamping column is equipped with screw, and described two screws are connected by bolt.
Further, described clamping band is metal tape, for example Stainless Steel Band.
The fastener inwall is provided with the muscle of protrusion, and good sealing effect increases fastener intensity, and fastener inwall seam crossing is through polishing, be processed into blade type, it can well be fitted, do not stay gap, the fastener upper end is provided with bolt, and bolt two is provided with the column type fixing device, can make the better fastening clip of bolt.
Traditional PE droping irrigating pipe one end is the pawl shape, and an end is plane, and when two terminated to together, the muscle of fastener inwall can combine with the pawl of pipeline opening very securely, forms sealing configuration.
The utility model has the advantage of: guaranteed the sealing of pipe joint, can not leak because the pressure in pipeline causes greatly the pipe joint place (or disengagement), easy for installation, compressive resistance is strong, and cost is low, better to soft band installation effect, adopt steel band, good springiness, pulling force is strong.
The utility model is described in further detail below in conjunction with drawings and Examples.
The accompanying drawing explanation
Fig. 1 is the utility model embodiment's structural representation;
Fig. 2 is the A-B face sectional view of Fig. 1;
In figure: 1-clamping band, 2-convex tendon, 3-clamping column, 4-bolt.
Embodiment
Below preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for description and interpretation the utility model, and be not used in restriction the utility model.
As depicted in figs. 1 and 2, a kind of pipe coupling fastener, comprise circular clamping band 1, described clamping band is metal tape, Stainless Steel Band for example, the inwall of described clamping band 1 alongst is provided with convex tendon 2, convex tendon 2 forms by machine roll extrusion clamping band, the A face forms the groove fallen in, the B face forms the muscle protruded, clamping band 1 inwall seam crossing is through polishing, it can well be fitted, do not stay gap, the length of described clamping band 1 is greater than the girth of described annulus, be that described clamping band 1 part is overlapping, the outside, two ends of described clamping band 1 is respectively equipped with clamping column 3, described clamping column 3 is equipped with screw, described two screws are connected by bolt 4, by bolt, clamping band is clamped.
Finally it should be noted that: the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although with reference to previous embodiment, the utility model is had been described in detail, for a person skilled in the art, it still can be modified to the technological scheme that aforementioned each embodiment puts down in writing, or part technical characteristics wherein is equal to replacement.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
