Detailed Description
The invention will be further explained with reference to the drawings and the specific embodiments.
The utility model provides a take check valve screw thread air cock, includes screw thread seat 1, check valve 2 and screw thread cap 3, characterized by: 1 upper portion of spiral shell tooth seat is equipped with aerifys chamber 16, 1 upper portion of spiral shell tooth seat is followed outward and is equipped with stopper 13, and 1 outside upper portion of spiral shell tooth seat is equipped with air escape groove 15, air escape groove 15 tip is equipped with the escape hole 17 that runs through, and 1 middle part inner wall of spiral shell tooth seat is equipped with sealing ring 14, sealing ring 15 inboard is equipped with air vent 11, 1 lower part of spiral shell tooth seat is equipped with outer tooth 12. The check valve 2 comprises a valve body 21 and a guide rod 22, a limiting ball 221 is arranged on the guide rod, and the bottom of the guide rod 22 is connected with the valve body 21. An air inlet hole 32 is formed in the top of the screw cap 3, an inflatable insert ring 34 is arranged on the outer side of the air inlet hole 32, after the inflatable insert ring 34 exits from the inflatable cavity 16, an air escape groove 15 and an air escape hole 17 in the outer side of the screw seat 1 form an air escape channel, inner threads 31 are arranged on the inner wall of the screw cap 3, the screw cap 3 is in threaded connection with outer threads 12 of the screw seat 1 through the inner threads 31 in a matched mode, a valve body fixing hole 33 is formed in the center of the screw cap 3, the guide rod 22 penetrates through the valve body fixing hole 33, the limiting ball 221 is fixed at the upper end of the valve body fixing hole 33, and the valve body 21 is fixed below the air inlet hole 32; the inflatable insert ring 34 is tightly matched with the inflatable cavity 16 at the upper part of the thread seat 1; the limiting block 13 limits the displacement of the screw thread cap 3 and the screw thread seat 1, so that the screw thread cap and the screw thread seat are not easy to separate.
When in inflation, the screw cap 3 is rotated anticlockwise, the screw cap 3 is rotated to the middle part of the screw seat 1, so that the valve body leaves the sealing ring 14, an inflation cavity 16 is formed between the valve body 21 and the sealing ring 14, gas is conveyed from the air inlet 32, and the gas enters the interior of an object to be inflated through the inflation cavity 16 and the vent hole 11.
