Specific implementation mode
The following is specific embodiments of the present invention, and in conjunction with attached drawing, the present invention will be further described
As shown in Figure 4 and Figure 5, a kind of error protection rapid air inflation connector, including two hollow relatively buckled fixations
Connector 1 and shift joint 2, are equipped with error protection component 5 on anchor tip 1.3 center of anchor tip main body is provided with cylindrical
Air passage, 3 upper end of anchor tip main body are equipped with the oblique screw thread of fast and easy snapping；3 central aeration road upper end of anchor tip main body
Mouth is opened there are one seam allowance, and sealing rubber ring 4 is fixed in 3 seam allowance of anchor tip main body, and 4 upper surface of sealing rubber ring is slightly higher than fixed
3 upper surface of adapter body；3 central aeration road of anchor tip main body connects air source.Shift joint 2 includes 9 He of shift joint main body
Gas transmission pipe fitting 10；9 center of shift joint main body is provided with cylindrical air passage, and 9 lower end of shift joint main body is equipped with to be connect with fixation
The head matched oblique screw thread of main body 3, shift joint main body 9 pass through two oblique screw thread Quick fastenings with anchor tip main body 3；It is moving
Dynamic 9 central aeration road lower end of adapter body opens that there are one seam allowances, and gas transmission pipe fitting 10 pierces into 9 air passage of shift joint main body, defeated
10 end of tracheae part is fixed in 9 seam allowance of shift joint main body.Shift joint main body 9 is sealed with after 3 snapping of anchor tip main body
Cushion rubber 4 is against 10 end of gas transmission pipe fitting, plays sealing function.
Shown in Fig. 6 to Fig. 8, error protection component 5 includes shell 6, mandril 7 and spring 8.3 side of anchor tip main body
It is provided with mounting hole outside wall, mounting hole bottom is provided with the stomata for being connected to 3 air passage of anchor tip main body, interior spiral shell is provided in mounting hole
Line.Shell 6 is in cylindrical tube shape, and 6 outside of shell is provided with to be threadedly coupled solid with the matched external screw thread of mounting hole internal thread, shell 6
It is scheduled in 3 mounting hole of anchor tip main body；6 center of shell is provided with cylindrical slideway, slideway and 3 mounting hole phase of anchor tip main body
Together.Mandril 7 is slidably mounted in 6 slideway of shell, has the half the circumference of the sleeve where it joins the shoulder with 6 inner wall sliding fit of shell, mandril 7 to lift on the outside of 7 inner end of mandril
The outer circumference surface of shoulder is equipped with sealing ring, ensures that mandril 7 is slidably connected with shell 6, and ensure air-tightness, comes from anchor tip
Gas in 3 air passage of main body can be pushed and be moved outside mandril 7；After mandril 7 moves outward, 7 outer end of mandril is against movement and connects
First 2 side, prevents shift joint from exiting anchor tip.The half the circumference of the sleeve where it joins the shoulder of limit is equipped on 6 outer end inner wall of shell, spring 8 is sleeved on
On mandril 7,8 inner end of spring is against on 7 half the circumference of the sleeve where it joins the shoulder of mandril, and 8 outer end of spring is against on 6 half the circumference of the sleeve where it joins the shoulder of shell, and spring 8 gives mandril 7 one
Inside side-thrust, when ensureing 3 air passage of anchor tip main body without air pressure, spring 8 promotes mandril 7 in anchor tip main body 3；It protects
The smooth Quick fastening of shift joint is demonstrate,proved on anchor tip.
If Fig. 9 shows, under peacetime state, mandril 7 is retracted under the action of spring 8, does not interfere with two button connectors
Rapid abutting joint ensure that using for the present invention is convenient and quick.
Such as Figure 10, in the deflated condition, the gas in loading line enters anti-difference by the aperture in anchor tip main body 3
Wrong component 5 pushes mandril 7 to stretch out, so that shift joint is locked on anchor tip, two connectors is prevented to be opened.Error protection group
The air-tightness of part 5 is mainly ensured by machining accuracy.After inflation, the air pressure in pipeline reduces, and mandril 7 is in spring 8
Effect is lower to retract, and two connectors is enable quickly to open.
