Description
Technical field
The invention belongs to technical field of pipeline connection, it is related to a kind of connection of plastic flexible pipe, more particularly, to a kind of plastics
Gladhand.
Background technology
At present, plastics (PP-R) the pipe fitting kind in domestic hot-water heating market has a lot, general flexible pipe with delivery port junction
Need to ensure the steadiness of its connection, but delivery port is generally the hard mouth of pipe of metal tube or other materials, plastic flexible pipe will be with
Hard mouth of pipe connection difficulty is larger；When pipeline needs branch, then need to be turned by pipelines such as threeways at pipe branch
Connect, also usually need the pipe fitting by flexible pipe and hard to be attached.In the prior art, plastic pipe is carried out by hot-melt technology
Connection can reach good connection effect, but hot-melt adhesive paste needs special hot melting equipment, and operation is inconvenient, and particularly exist
When high-altitude is installed or narrow space is installed, installment work will become very difficult；And existing quickly connecing for flexible pipe connection
Head, majority makes for metal material, and cost of manufacture is high, and difficulty of processing is big, and its weight is larger, and cost of transportation is higher so that its
Price commercially is higher；And as the pipe fitting joint of metal, often aged deterioration is all internal finding, pipe fitting connects
The head life-span of itself, and internal small-sized accessory can not be often individually replaced, whole pipe fitting joint considerably beyond the life-span of pipeline
Integral replacing, causes use cost to greatly increase, and the waste of its raw material resources is also caused to a certain extent.
The content of the invention
In order to solve the above problems, the invention provides a kind of plastic flexible pipe snap joint, so as to reach pipe fitting and pipe
Convenient and fast connection, the solid and reliable effect of son.
The present invention is achieved by following technical solution.
A kind of plastic flexible pipe snap joint, including pipe fitting, the pipe fitting two ends are arranged with locking end cap and locking
Sleeve, sealing ring is additionally provided with pipe fitting outer wall, and sealing ring is O-shaped rubber ring, and quantity is each 2 of one end；The pipe fitting two
Outer wall is held to be provided with sealing ring mounting groove.
Pipe fitting two ends outer wall is provided with pawl structure, and pipe fitting two ends outer wall is provided with air groove；The locking
The inwall bottom of end cap is provided with locating slot, and the clamping slot depth is 0.3mm~0.4mm；The locking sleeve two ends are respectively
Horn opening A structures and horn opening B structure；The horn opening B ends are to set horn mouth, horn mouth again after first shrinking
The locating slot groove bottom equal diameters that external diameter is covered with locking end；The pipe fitting and locking end cap are made by PP-R plastics.
The beneficial effects of the invention are as follows：
A kind of plastic flexible pipe snap joint of the present invention, passes through pipe fitting and locking end cap, common group of locking sleeve
Into clamping structure, hose coupling is firmly clamped, the effect of quick connection has been reached；Pipe fitting is made using plastics
Body and locking end cap, only locking sleeve is thin-wall metal product, greatlys save the material cost of pipe fitting, reduces each part
Difficulty of processing, alleviate product weight；Pipe fitting each several part is absolute construction, and part part exchanging can be achieved, even if overall
Change, replacement cost is relatively low, makes consumer acceptant.

Embodiment
Technical scheme is further described below in conjunction with the accompanying drawings, but claimed scope is not limited to institute
State.
As shown in figs. 1 to 6, a kind of plastic flexible pipe snap joint of the present invention, including pipe fitting 1, the pipe fitting 1
Two ends are arranged with locking end cap 2 and locking sleeve 3, are interference fitted between locking end cap 2 and pipe fitting 1, and pass through pipe fitting 1
On step end face positioning, be additionally provided with sealing ring 4 in the outer wall of pipe fitting 1；Pipe fitting 1 and locking end cap 2 are by PP-R plastics systems
Into locking sleeve 3 is made up of metal material.
The sealing ring 4 is O-shaped rubber ring, and quantity is one end 2, to ensure sealed reliable；Outside the two ends of pipe fitting 1
Wall is provided with sealing ring mounting groove 101 corresponding with sealing ring 4, so as to the location and installation of sealing ring 4, the outside of sealing ring 4 and flexible pipe 5
Inwall is fitted, and forms sealing structure.
The two ends outer wall of pipe fitting 1 is provided with pawl structure 102, and the inwall of flexible pipe 5 is contacted with pawl, to increase flexible pipe 5
The resistance exited from pipe fitting 1, improves the fastness that flexible pipe 5 is connected with pipe fitting 1；Set on the two ends outer wall of pipe fitting 1
There is air groove 104, when flexible pipe 5 is connected with pipe fitting 1, inner air can increase the resistance of the tube wall of flexible pipe 5 entrance, by setting
