The lower end of female connector, upper joint sleeve is plugged in the cavity of rubber stopper and sleeve is fixed with upper chuck, and upper chuck is pressed against rubber stopper
On the upper bottom surface of cavity, screw thread, tension spring are formed on the outer wall of the upper joint sleeve lower end and the outer wall of lower joint sleeve upper end
Both ends be screwed onto on upper joint sleeve and lower joint sleeve respectively；Air inlet pipe is plugged in the upper joint sleeve, under air inlet pipe
Hold plugged and fixed in lower joint sleeve, the upper end of the upper end exposing upper joint sleeve of air inlet pipe forms threaded connection seat, and screw thread connects
Tracheae quick union is bolted on joint chair.
Preferably, the length of the air inlet pipe is more than the length of rubber stopper.
Preferably, the aperture of the lower joint sleeve inner wall is less than the aperture of upper joint sleeve inner wall.
Preferably, screw thread is formed on the inner wall of the lower joint sleeve, the lower end of air inlet pipe forms screw thread, air inlet pipe spiral shell
It connects and is fixed in lower joint sleeve.
Preferably, if forming the groove of arterial highway annular on the inner wall of the upper joint sleeve, the groove interpolation of upper joint sleeve
It connects and is fixed with sealing ring, sealing ring is pressed against on the outer wall of air inlet pipe.
Preferably, the length of the tension spring is less than the length of rubber stopper.
The beneficial effects of the present invention are：Its is simple in structure, the disengaging using the principle of rubber compressive deformation to radiator
The mouth of a river is sealed, and can bear larger air pressure without causing rubber plug to be detached from radiator.
Description of the drawings：

Specific implementation mode：
Embodiment：See shown in Fig. 1 to 2, a kind of rubber seal air inlet plug, includes the rubber stopper 6 of cone, rubber stopper 6
Inside forms cavity 61, be plugged on the lower face of rubber stopper 6 in be inverted T-type shape lower joint sleeve 1, lower joint sleeve 1 it is upper
End is plugged in the cavity of rubber stopper 6 and sleeve is fixed with lower chuck 3, and lower chuck 3 is pressed against 61 bottom surface of cavity of rubber stopper 6
On, the upper joint sleeve 2 of T-type is plugged on the upper surface of rubber stopper 6, the lower end of upper joint sleeve 2 is plugged in the cavity 61 of rubber stopper 6
Interior and sleeve is fixed with upper chuck 4, and upper chuck 4 is pressed against on the upper bottom surface of 6 cavity 61 of rubber stopper, 2 lower end of the upper joint sleeve
1 upper end of outer wall and lower joint sleeve outer wall on form screw thread, the both ends of tension spring 7 be screwed onto respectively upper joint sleeve 2 and under
On connector sleeve 1；Air inlet pipe 5 is plugged in the upper joint sleeve 2, the lower end plugged and fixed of air inlet pipe 5 in lower joint sleeve 1,
The upper end that upper joint sleeve 2 is exposed in the upper end of air inlet pipe 5 forms threaded connection seat 51, and it is fast to be bolted with tracheae on threaded connection seat 51
Connector 8.
Preferably, the length of the air inlet pipe 5 is more than the length of rubber stopper 6.
