Raw not bonding phenomenon.The design of annular anti-skid bulge causes the first hose transition and described second on male contact 1 and famale connector 2
The profile of hose transition is fir tree, and Chinese fir end is used to be connected with nylon tube provided with connecting portion O-ring seal；
It is generally used for fuel conduit, conveying and return line, gas exhaust piping, fuel tank drain line and oil cooling pipe road etc., institute in pipeline
Logical medium includes gasoline, diesel oil, urea, methanol, gas and water etc..
Whether male contact 1 is fully inserted into famale connector, is determined according to whether upper cover body 3 can close；Famale connector 2
Leading section uses dissection type, simple and convenient；Only male contact 1 is installed in place, the front and rear sides of the shelves ring 32 difference energy on famale connector 2
The second annular boss 14 and first annular boss 12 of male contact are enough blocked, male contact 1 is firmly locked into famale connector 2；Work as sun
Inside the fully-inserted famale connector of joint 1, the upper cover body and lower cover 4 of famale connector 2 are locked by upper lock 31 and lower lock 41
Tightly；The angle of shelves 32 clamping male contacts 1 of ring is 180 °；Cooperation and upper safety buckle 33 between upper lock 31 and lower lock 41
With the cooperation of lower safety buckle 44, dual buckle structure ensure that the reliability of locking.
As shown in Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, famale connector 2 is using the structure of dissection type, and lower cover 4 and famale connector 2 connect
One is connected in, upper cover body 3 is rotated by rotating shaft installation portion 42 of the rotating shaft 35 on lower cover, and upper cover body 3 and lower cover 4 can
To be locked by dual buckle structure, the lower lock fillet 43 of the upper lock inclined-plane 32 of upper lock 31 and lower lock 41 is protected
The convenience of clamping is demonstrate,proved.The clamping of upper lock 31 and lower lock 41 ensures that upper cover body 3 and lower cover 4 align, then upper safety
The locking of button 33 and lower safety buckle 44 ensures upper cover body 3 and lower cover 4 does not depart from phenomenon completely, and dual buckle structure ensures
The phenomenon that male contact 1 will not fall off, misplace because of vibrations and famale connector 2.
As shown in Fig. 1, Fig. 5 and Fig. 6, the surface of upper lock 31 is designed with lock inclined-plane 34, and its indoor design has a grade ring
32, the radius of the radius of shelves ring 32 and the Access Division 13 of male contact is equal, and can with the Access Division 13 of 180 ° of covering male contacts, and
Shelves ring 32 is close to the first annular boss 12 of male contact, when male contact does not have to insert completely, the first ring of male contact
Shape boss 12 can hinder shelves ring 32, so as to stop that the upper cover body 3 of famale connector is closed；The first annular boss of other male contact
12 also indicate that male contact is not inserted in place with no fit completely of the shelves ring 32 of famale connector.
As shown in Figure 9 and Figure 10, the lower cover 4 of the leading section of famale connector 2 is provided with rectangular channel, to be put into U-shaped card lock 5, square
Shape groove outer surface is provided with the first elastic elastic cam 52 of cam 53 and second, can lock U-shaped card lock outer surface 51, elasticity is convex
The upper surface of button uses arc-shaped, and U-shaped card lock 5 is more convenient for being caught in elastic cam 52,53, while the internal diameter of U-shaped card lock 5
Equal to the radius of the Access Division 13 of male contact 1, can preferably it be covered on the surface of male contact 1, and U-shaped card lock outer surface 51
Equal with the length and width of famale connector rectangular channel, 360 ° are covered on male contact 1 together with the shelves ring 32 of upper cover body 3, play dust-proof
The effect of anti-gray.
The present invention application method be：When male contact 1 needs inserting, user is first the upper cover body 3 dozens of famale connector 2
Open, U-shaped card lock 5 in lower cover 4 is pulled out from inside to outside along rectangular channel, be that U-shaped card lock 5 is moved to when lock fork 55 encounters lower cover 4
Maximum position, this is that male contact 1 can be injected in famale connector 2, and until male contact 1 is inserted in place, at this moment user can use
Upper cover body 3 is checked that upper cover body 3 smoothly can close, then male contact 1 is inserted in place, if the process that upper cover body 3 is closed
Stopped by the first annular boss 12 of male contact 1 and can not be closed, then male contact 1 is not inserted in place；Upper cover body 3 is locked
The lower lock 41 of button 31 and lower cover 4 carries out clamping, then the upper safety buckle 33 of upper lock 31 and the lower safety buckle of lower lock 41
44 carry out clamping, then, and the U-shaped card lock 5 of lower cover 4 is moved down, and clamping lock supporting surface 54 is completely covered on the Access Division 13 of male contact,
The first elastic elastic cam 52 of cam 53, second on lower cover 4 blocks U-shaped card lock outer surface 51, plays and locks 5 to U-shaped card
Positioning, locking effect；So as to which male contact is locked in famale connector 2.
When male contact 1 needs to be pulled outwardly out, user opens firstly the need of by upper lock with lower lock, due to locking
Buckle provided with upper lock inclined-plane, lower lock is provided with lower lock fillet, and upper lock inclined-plane can be moved downward first further along lower lock
Fillet is moved up, and is then departed from the upper lock 33 and lower lock 44 of upper cover body 3 and lower cover 4, upper cover body 3 just can be with around the shaft 35
Rotate, so that open mode, then makes U-shaped card lock 5 and tilt certain angle, U-shaped card lock 5 causes the first elastic cam 53, second
Elastic cam 52 has certain slight elastic deformation, and at this moment U-shaped card lock outer surface 51 departs from elastic cam, until in lock fork 55
When restriction protrusion is encountered lower cover 4 and can not pulled out again, U-shaped card lock 5 just moves ultimate range to, and male contact 1 just can be from the moon
Pulled out in joint 2.
The present invention is easy to loading and unloading and has the U-shaped card lock 5 on dual buckle structure, lower cover 4 and the shelves ring 32 of upper cover body 3
