Abstract
The utility model relates to a quick coupler for a blind tube. The quick coupler comprises a coupler main body and is characterized in that a plurality of inverted triangular sealing teeth are symmetrically formed in the coupler main body; and bell mouths are respectively formed in two ends of the inverted triangular sealing teeth. The quick coupler disclosed by the utility model is simple in structure and convenient to use; the aim of multiple functions by one pipe can be achieved and the development cost of a die is reduced; and meanwhile, the size is reduced, so that the difficulty in inventory management for manufacturers and customers is reduced and the management cost is reduced.
Description
Technical field
The utility model relates to a kind of rapid pipe joint, relates in particular to a kind of blind pipe rapid pipe joint.
Background technique
In agricultural water-saving irrigation engineering construction process, need interspersed PE rapid pipe joint in blind pipe in order to be communicated with each section blind pipe, connect the purpose that connects to reach pipeline rehabilitation.PE blind pipe in the market is diversified in specifications, and the PE pipe of diameter of the same race also has multiple wall thickness.PE blind pipe corresponding to every kind of specification will have corresponding PE joint; This has just greatly increased the mould development cost and the stock control expense of pipe fitting manufacturer; Easily the rapid pipe joint of different size is obscured simultaneously, engineering construction personnel's use is caused great inconvenience.
The model utility content
The utility model technical problem to be solved provides a kind of blind pipe rapid pipe joint simple in structure, easy to use.
For addressing the above problem, the described a kind of blind pipe rapid pipe joint of the utility model comprises adapter body, and it is characterized in that: be arranged with the sealing pawl that multiple tracks is the inverted triangle shape on the said adapter body, its two ends are equipped with bellmouth.
The diameter of said sealing pawl is increased progressively to the center by the end.
Said bellmouth diameter is less than the internal diameter of PE blind pipe.
The utility model compared with prior art has the following advantages:
1, is the inverted triangle shape owing to seal pawl in the utility model, therefore, helps the enlarging of PE blind pipe.
2, since in the utility model the diameter of sealing pawl increase progressively to the center by the end, therefore, PE blind pipe that can supporting different wall uses.
3, owing to bellmouth in the utility model is positioned at the adapter body front end, therefore, can play the guiding role during installation.
4, owing to be provided with multiple-sealed pawl in the utility model, therefore, can realize the purpose of one tube multipurpose, and reduce the mould development cost; Simultaneously because specification reduces, the difficulty for manufacturer and client have reduced stock control has reduced administration cost.
5, the utility model is simple in structure, easy to use.
Description of drawings
Below in conjunction with accompanying drawing the embodiment of the utility model is done further detailed explanation.
Fig. 1 is the sectional view of the utility model.
Among the figure: 1-adapter body 2-sealing pawl 3-bellmouth.
Embodiment
As shown in Figure 1, a kind of blind pipe rapid pipe joint comprises adapter body 1.Be arranged with multiple tracks on the adapter body 1 and be the sealing pawl 2 of inverted triangle shape, its two ends are equipped with bellmouth 3.
Wherein: the diameter of sealing pawl 2 is increased progressively to the center by the end.Bellmouth 3 diameters are less than the internal diameter of PE blind pipe.
Claims (3)
1. blind pipe rapid pipe joint comprises adapter body (1), it is characterized in that: be arranged with the sealing pawl (2) that multiple tracks is the inverted triangle shape on the said adapter body (1), its two ends are equipped with bellmouth (3).
2. a kind of blind pipe rapid pipe joint as claimed in claim 1 is characterized in that: the diameter of said sealing pawl (2) is increased progressively to the center by the end.
3. a kind of blind pipe rapid pipe joint as claimed in claim 1 is characterized in that: said bellmouth (3) diameter is less than the internal diameter of PE blind pipe.
