Existing a kind of Novel connection connection technology that metal tube is connected is to adopt the groove type interconnection technique, generally comprise and a pair ofly be fastened on the semicircle clip that needs mouth of pipe place, butt tube road and be arranged on the ring packing cushion rubber in the concave cavity in the middle of the clip, the clip two ends have a fixed-use bolt hole, be respectively equipped with a circle boss on the clip buckling surface that is interlocked with pipeline, this boss is stuck in the groove that needs mouth of pipe place, butt tube road.If when the pipe clamp of this kind structure is connected plastic tube, need the fluting at plastic tube mouth of pipe place, and behind the plastic tube fluting, tube wall is easy to cracking, so this kind plough groove type pipe joint can't be used for connecting plastic tube.And traditional plastic tube Placement adopts hot melt (or electric smelting) method to connect usually, and this Placement needs special device, requires very high to pipe fitting end face turbidity test.And must cut during dismounting, still need again welding when reconnecting.Waste time and energy, especially outstanding to the occasion drawback of the frequent dismounting of need.

Summary of the invention

The purpose of this utility model is to connect pipe clamp and can't be used for connecting plastic tube in order to solve groove pipe that prior art exists, and waste time and energy when adopting the conventional hot melt method to connect, need the repeatedly technical problems such as cutting, welding during dismounting, and a kind of zigzag fashion PE pipe clamp that can carry out easily the dismounting connection to plastic tube that provides.

In order to solve the problems of the technologies described above, the utility model is achieved by the following technical solutions:

A kind of zigzag fashion PE pipe clamp, it comprises the semicircle clip that a pair of connecting tube that is fastened on pipeline mouth of pipe place is used, the two ends of described semicircle clip are provided with the fixing lug of using, described clip comprises the twice buckling surface that is fastened on the pipeline, and the clip inner chamber between the twice buckling surface, in the described clip inner chamber O-ring seal is set, some outstanding sawtooth are set on the described buckling surface.

In the further detailed structure of the utility model, also has following characteristics: the strengthening groove that forms indent in the middle of the described sawtooth.

In the further detailed structure of the utility model, also have following characteristics: the centre of described O-ring seal is provided with outstanding annular seal lip limit.

In the further detailed structure of the utility model, also have following characteristics: an end of described clip inner chamber forms boss, and the other end forms concave station.

In the further detailed structure of the utility model, also have following characteristics: the both sides of described clip arrange respectively two lugs, respectively have a bolt hole on each lug.

Compared with prior art, advantage of the present utility model and good effect are: because the utility model has adopted said structure, can conveniently connect plastic pipe, and need not welding and less demanding to the end surfaces turbidity test when connecting, need not cut during dismounting, easy accessibility, time saving and energy saving, be particularly useful for needing the occasion of frequent dismounting.Time saving and energy saving when adopting the utility model connecting tube, improved widely working efficiency, reduced cost.

Embodiment

For making the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with accompanying drawing the technical solution of the utility model is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who obtains under the creative work prerequisite, all belong to the scope of the utility model protection.

Referring to Fig. 1-Fig. 5, the utility model zigzag fashion PE pipe clamp comprises the semicircle clip 10 that a pair of connecting tube that is fastened on plastic pipe 40 mouth of pipe places is used, the two ends of described semicircle clip 10 are provided with fixing with lug 20, described clip 10 comprises the twice buckling surface 12 that is fastened on the pipeline, and the clip inner chamber 11 between the twice buckling surface 12, the described clip inner chamber 11 interior O-ring seals 30 that arrange, some outstanding sawtooth 121 are set on the described buckling surface 12, can be bumped into pipeline 40 surfaces, arbitrarily mobile to prevent clip 10.

Further, in order to increase the tensile strength of sawtooth 121, make it can not cause not sawtooth 121 to be broken because of plastic pipe 40 hardness, form the strengthening groove 122 of indent in the middle of the described sawtooth 121.

Further, in order to reach better sealing effect, the centre of described O-ring seal 30 is provided with outstanding annular seal lip limit 31.

Realize that rigidity cooperates when a pair of semicircle clip 10 is fastened, fasten more close and firm, an end of described clip inner chamber 11 forms boss 112, and the other end forms concave station 111.The boss 112 of a pair of clip 10 and concave station 111 position opposite settings, the boss 112 of front band is inserted in the concave station 111 of lower catch hoop, the boss 112 of lower catch hoop is inserted in the concave station 111 of front band, the more close and firm that this a pair of upper and lower clip 10 is fastened at pipeline 40.

In order to make PE pipe clamp sawtooth 121 can more firmly be bumped into pipeline 40 surfaces, and make upper and lower clip 10 fastening more convenient, the both sides of described clip 10 arrange respectively two lugs 20, respectively have a bolt hole 21 on each lug 20.

When the utility model uses, first O-ring seal 30 is enclosed within the end of a pipeline 40, with another root pipeline to it, reserve certain pipe end gap, then O-ring seal 30 is moved on another pipeline, make the pipe end that entangles two pipelines 40 of O-ring seal 30 symmetries.Again two semicircle clips 10 are enclosed within on the pipeline 40, O-ring seal 30 just in time places 11 li of the clip inner chambers of clip 10 indents, the bolt hole 21 of clip 10 both sides simultaneously aligns, adopt at last bolt to apply certain pretightening force, make on clip 10 buckling surfaces 12 sawtooth 121 tightly be bumped into pipeline 40 surfaces, thereby realize the connection of two plastic pipes 40.

It should be noted that at last: above embodiment only in order to the technical solution of the utility model to be described, is not intended to limit; Although with reference to previous embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technological scheme that previous embodiment is put down in writing, and perhaps part technical characteristics wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of the utility model embodiment technological scheme.
