The quick release reliever comprises an upper joint, a lower joint, clamping rings, pins, steel balls, semicircular rings, a gasket and a locating pin. The upper joint is provided with a groove, the two semicircular rings are hooped through the two clamping rings to be fixed in the groove, the two pins are clamped at the positions of openings of the two clamping rings respectively, the locating pin is positioned between the two semicircular rings, four round holes are symmetrically distributed in the inner wall of the groove of the upper joint, each round hole can accommodate one steel ball, the rubber gasket is positioned at the joint of the bottom of the upper joint and the lower joint, and the two joints form an airtight channel after being connected. The quick release reliever is suitable for a canopy with an airtight system, simple and convenient to operate, safe and reliable and suitable for aircraft canopy airtight systems of various models, and can also be used for quick separation of other low-pressure pipes and have high promotional values.
Description
Technical field
The present invention relates to a kind of release, particularly relate to a kind of aircraft low pressure line quick-release release.
Background technique
Aircraft low pressure line quick-release release is the constituent element of canopy leak-tight system release, and its effect is the connection of separation block hatchcover airtight hose and leak-tight system, to carry out the operation of dismounting hatchcover.
The joint that traditional canopy leak-tight system release uses, first need dismantle clip during separation, then cut off safety fuse cutout, finally turn on joint, this process is comparatively loaded down with trivial details, is unfavorable for the quick-detachment of portable cover when safeguarding.
Therefore, need to provide a kind of new technological scheme to solve the problems referred to above.
Summary of the invention
The technical issues that need to address of the present invention are to provide a kind of aircraft low pressure line quick-release release.Make canopy leak-tight system flexible pipe quick separating, improve the maintenance efficiency of canopy system.
For solving technical problem of the present invention, the technical solution used in the present invention is:
A kind of aircraft low pressure line quick-release release, it comprises upper connection, lower contact, snap ring, pin, steel ball, semicircular ring, packing ring and locating stud, described upper connection has a groove, two semicircular ring are waled by two snap rings and are fixed in groove, two snap ring openings block a pin respectively, a locating stud is had in the middle of two semicircular ring, the groove inner wall of described upper connection is symmetrically distributed with four circular holes, a steel ball can be placed in each circular hole, a rubber washer is had with lower contact joint bottom described upper connection, airtight path is formed after two joints connect.
Described upper connection top is provided with upper adapter, and zigzag fashion is formed at described upper adapter top, and described upper adapter bottom is smooth pipe.
Beneficial effect of the present invention: quick-release release of the present invention is applicable to the canopy of leak-tight system, this structure operation is easy, safe and reliable, makes canopy leak-tight system flexible pipe quick separating, improves the maintenance efficiency of canopy system.

Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.Following examples, only for illustration of the present invention, are not used for limiting the scope of the invention.
As shown in Fig. 1 and Fig. 1 a, a kind of aircraft low pressure line quick-release release of the present invention, it comprises upper connection 1, lower contact 4, snap ring 3, pin 7, steel ball 6, semicircular ring 5, packing ring 2 and locating stud 8, upper connection 1 has a groove 9, two semicircular ring 5 are waled by two snap rings 3 and are fixed in groove 9, two snap ring 3 openings block a pin 7 respectively, rotate for preventing snap ring 3, a locating stud 8 is had in the middle of two semicircular ring 5, groove 9 inwall of upper connection 1 is symmetrically distributed with four circular holes 11, a steel ball 6 can be placed in each circular hole 11, the large I of circular hole ensures that steel ball is inserted but do not pass hole.Airtight path 10 is formed have a rubber washer 2, two joint to connect bottom upper connection 1 with lower contact 4 joint after.
As shown in Figure 2 a, quick-release release utilizes the elasticity of snap ring 3 to realize the plug of joint with fixing.When upper connection 1 is inserted in lower contact 4, lower contact 4 extrudes the steel ball 6 be placed in upper connection 1 circular hole 11 makes semicircular ring 5 separately, now snap ring 3 is in softened state, after lower contact 4 enters upper connection 1, snap ring 3 recovers nature, two semicircular ring 5 close, and steel ball 6 is just in time stuck between lower contact 4 and semicircular ring 5, upper and lower fittings.As shown in Figure 2 b, when needs dismounting release, only need slightly exert oneself lower contact to pull out, namely upper and lower joint be separated.
When quick-release release uses on machine, its upper adapter 12 is connected with flexible pipe, and extract upper connection 1 owing to needing to hold upper adapter 12 during dismounting joint with the attachment portion of flexible pipe, the connection request meeting mouth place is more fastening.Connect more reliable for making to connect mouth, upper adapter upper design toothing, increase the friction with flexible pipe, upper adapter bottom is smooth pipe, in outside adds fastening ring after being connected with flexible pipe, reduces the risk come off further.
Quick-disconnect release of the present invention has the following advantages:
A) reliably can be connected to form the passage that supplied gas flows through with leak-tight system remaining part, automatically can not throw off under various regime of flight, be connected firmly, air tight;
B) when portable cover is dismantled, can simply, separating joint rapidly;
C) wear resistance is good, the excessive abrasion that structural member there will not be part normally to work.
Quick-release release of the present invention is applicable to the canopy of leak-tight system, and this structure operation is easy, safe and reliable, is applicable to the canopy leak-tight system of various model, also may be used for the quick separating of other low pressure line, have higher promotional value.
