Tooth, the latch is towards clamping seat.
By using above-mentioned technical proposal, it is designed to make claw realization unidirectionally to penetrate water pipe towards clamping seat latch
Effect, water pipe is not extracted reversely, improve clamping effect.
Preferably, described only offer slid chamber on ring, slid in the slid chamber and be connected with expansion link, it is described to stretch
Contracting bar is connected on the end face of spacing ring.
By using above-mentioned technical proposal, the design of expansion link can make the spacing ring of connection inner tube press to claw, so as to
The degree of being connected firmly between water pipe and claw is lifted, the sealing effectiveness of O-ring can also be lifted.
Expansion link is driven to have to spacing ring side preferably, being additionally provided between the expansion link and the bottom of slid chamber
To the elastic component of sliding motion trend.
By using above-mentioned technical proposal, the design of elastic component can make expansion link have the state stretched out all the time, pacify
During dress, spring-compressed, water pipe is set to be connected on spacing ring, after installation, spring exerts a force spacing ring claw direction,
Because water pipe can not deviate from claw, during spacing ring is pushed outwardly, water pipe can be deformed upon, the both ends of water pipe are all by crowded
Pressure, so as to improve sealing effectiveness.
Preferably, the end set of the connection inner tube has guiding arc.
By using above-mentioned technical proposal, being oriented to the design of arc can facilitate the socket of water pipe to install.
Preferably, the limited block of the restricted expansion link abjection slid chamber of the upper setting of the expansion link.
By using above-mentioned technical proposal, the design of limited block can avoid the completely out slid chamber of expansion link, work as connection
When outer tube is not connected to expansion link surface, expansion link still can be arranged in slid chamber, improve the stability of structure.
In summary, the utility model has the advantages that：
The water pipe head makes it have sealing by sealing ring, is further increased by the cooperation of expansion link and claw
Sealing effectiveness, avoid leak；Make the water pipe head that there is preferable firmness by claw, water pipe is limited by connecting inner tube
Connection end inwardly shrinks deformation, further increases the firmness that water pipe is connected with water pipe head；By clamping seat with it is close
The protection of tube sealing limits the deformation of claw, makes the clamping effect of claw more stable, makes the water pipe head by above-mentioned design
With preferable sealing, firmness, while there is longer service life.
