Abstract
The utility model discloses a quick connector for a plastic hose, which comprises the plastic hose and a connecting nut, wherein an annular connector with an outer diameter being larger than the outer diameter of the hose is directly formed on the end of the plastic hose, and the connecting nut is sleeved on the connector. The utility model has the advantages that the defects of the structure of the conventional quick connector, i.e. excessive fittings and poor leak tightness,can be overcome, and the quick connector for plastic hoses, which has the characteristics of less fittings, low machining cost and good connection tightness and is easy and convenient to mount is designed.
Description
Technical field
The utility model relates to plastic flexible pipe, particularly a kind of quick-acting joint of plastic flexible pipe.
Background technique
For realizing that plastic flexible pipe is connected with the quick of pipeline, valve, the two ends of plastic flexible pipe are provided with the quick-acting joint structure.
Existing quick-acting joint structure is as shown in Figure 1, it comprise a metal joint 1 ', metal connecting sleeve 2 ', coupling nut 3 ' and seal washer 4 '; Wherein metal joint 1 ' afterbody be provided with multiple tracks engaging protrusion 11 ', its direct interference fit insert plastic flexible pipe 5 ' in; Said connecting sleeve 2 ' be wrapped in inserts the plastic flexible pipe 5 ' outside of metal joint 1 ' afterbody, work in-process utilize stamping press to make its distortion and realize plastic flexible pipe 5 ' with metal joint 1 ' be connected.Said coupling nut 3 ' screw thread is nested with at metal joint 1 ' head outwardly; At this; Be to guarantee sealing, metal joint 1 ' back head and plastic tube 5 ' the end between be provided with said seal washer 4 ', metal joint 1 ' head front side be set as a taper fit face 12 '.
The problem that above quick-acting joint structure exists is that accessory is many, and processing cost is high, the assembling trouble, and plastic flexible pipe is realized with the compacting that is connected through the metal connecting sleeve of metal joint simultaneously, in the middle of actual, leaks because of adding not in place causing of punching press in man-hour through regular meeting.
The model utility content
To the problems referred to above, the utility model has designed a kind of quick-acting joint of plastic flexible pipe, and it has, and accessory is few, processing cost is low, assembling is easy, the characteristics of connection good airproof performance.
For realizing above-mentioned purpose, the utility model adopts following technological scheme:
A kind of quick-acting joint of plastic flexible pipe comprises plastic flexible pipe and coupling nut, it is characterized in that: said plastic flexible pipe directly generates the annular connecting head of an external diameter greater than hose outside diameter in its end, connecting head is being nested with coupling nut outward.
Above-mentioned connecting head end face is arranged to the fitting surface of a taper.
A seal washer is installed in the above-mentioned connecting head end face outside.
The utility model directly generates an annular connecting head by the plastic flexible pipe end; There is not leakage problem in being connected between connecting head and the plastic flexible pipe; Because of being all plastic material, processes annular connecting head simultaneously; It uses as joint on the one hand, has the effect of seal ring by the plastic deformation of plastic material on the other hand, can when connecting, guarantee the sealing between annular connecting head and the coupling nut.
The utility model structure only comprises connecting head and the coupling nut that the plastic flexible pipe end directly generates, and when guaranteeing sealing, has dwindled number of fitting parts at double, can effectively reduce manufacturing cost and promote efficiency of assembling.
In addition, for further strengthening the connection sealing of quick-acting joint, the sealing surface that the connecting head end face is arranged to a taper increases area of contact, and in the connecting head end face outside one seal washer is installed, and guarantees the sealing between annular connecting head and the coupling nut with this.
Description of drawings
The sectional view of Fig. 1, existing quick-acting joint structure;
The sectional view of Fig. 2, the utility model.
Embodiment
As shown in Figure 2, a kind of quick-acting joint of plastic flexible pipe comprises plastic flexible pipe 1 and coupling nut 2, and said plastic flexible pipe 1 directly generates the annular connecting head 11 of an external diameter greater than flexible pipe 1 external diameter in its end, the connecting head 11 outer coupling nuts 2 that are being nested with.
The utility model annular connecting head 11 is directly generated by plastic flexible pipe 1 end; There is not leakage problem in being connected between connecting head 11 and the plastic flexible pipe 1; Because of being all plastic material, processes annular connecting head 11 simultaneously; It uses as joint on the one hand, has the effect of seal ring by the good plasticity of plastic material on the other hand, can be when connecting guarantees the sealing between annular connecting head 11 and the coupling nut 2 through plastic deformation.
The utility model structure only includes the direct connecting head that generates 11 in plastic flexible pipe 1 end and is nested with coupling nut 2 above that, when guaranteeing sealing, has dwindled number of fitting parts at double, can effectively reduce manufacturing cost and lifting efficiency of assembling.
In addition; For further strengthening the connection sealing of quick-acting joint; The sealing surface 111 that connecting head 11 end faces are arranged to a taper increases area of contact, and in the connecting head 11 end faces outside one seal washer 3 is installed, and comes the sealing between dual assurance annular connecting head 11 and the coupling nut 2 with this.
To sum up, the utility model is a kind of quick-acting joint of plastic flexible pipe, and it has, and accessory is few, processing cost is low, assembling is easy, the characteristics of connection good airproof performance.
Claims (3)
