Description
Technical field
The utility model belongs to field of mechanical technique, is related to a kind of hydraulic quick coupling.
Background technology
Hydraulic joint is the joint for connecting two hydraulic oil pipes in fluid pressure line, and hydraulic quick coupling is exactly can
The hydraulic joint being enough quickly connected.Hydraulic quick coupling includes female joint and pin end, female joint and the public affairs being correspondingly arranged
Joint is also known as famale connector and male contact.
Chinese patent literature data, which discloses, proposes a kind of hydraulic quick coupling [application number：201410339070.X；It is open
Number：105318128A], including male contact and famale connector, sun of the male contact including male contact valve seat and in male contact valve seat
Joint valve element, is provided with spring A between male contact valve seat and male contact valve element, famale connector includes famale connector valve seat and is located at famale connector
Famale connector valve element in valve seat, the clamping part of spring B, male contact and famale connector is provided between famale connector valve seat and famale connector valve element
The outside divided is provided with lock housing, and lock housing is also known as lock tube, lock housing spring is provided between lock housing and famale connector, between lock housing and famale connector
Axle jump ring is additionally provided with, male contact also includes plug body A, and hole is provided between plug body A and the forward surface of male contact valve element and is blocked
Spring A, is provided with sealing ring A between the cone of male contact valve element front end and the connector for connecting back end cylindrical body, before plug body A
End outside is provided with to block the back stop slot of steel ball, and famale connector also includes plug body B, and plug body B is opposite with famale connector valve element
Hole jump ring B is provided between face, is provided between the cone of famale connector valve element front end and the connector for connecting back end cylindrical body close

Dynamic and ball motion, influences the use of hydraulic joint.If the free gap between lock housing and famale connector is removed, although can
Enter between lock housing and famale connector and paste on ball to reduce dust, but so can cause lock housing can not be in famale connector
Upper slip.
The content of the invention
The purpose of this utility model is in view of the above-mentioned problems existing in the prior art, it is proposed that a kind of hydraulic quick coupling,
The technical problem of solution is hydraulic quick coupling is ensured that slip of the lock tube in female joint is unaffected again
The dust-proof effect of hydraulic quick coupling can be improved.
The purpose of this utility model can be realized by following technical proposal：
A kind of hydraulic quick coupling, including female joint, mounting hole, the installation are provided with the lateral surface of the female joint
Ball is provided with hole, is arranged with the lock tube that ball can be limited in mounting hole outside the female joint, the lock tube can
Slided in female joint, it is characterised in that flexible seal in a ring is provided between the female joint and lock tube,
The outside portion of the seal is abutted on the medial surface of lock tube, and the inside portion of the seal abuts in the lateral surface of female joint
On, the outside portion of the seal can be slided on the medial surface of lock tube or the inside portion of the seal can connect in mother
Slided on the lateral surface of head.
When ball is installed, first ball is placed in mounting hole, then lock tube is sleeved on outside female joint, then slide lock
Set makes lock tube that ball is limited in mounting hole.Due to being provided with seal, and the outside of seal between lock tube and female joint
Portion and inside portion abut on the medial surface of lock tube and the lateral surface of female joint respectively, during the use of hydraulic quick coupling
Extraneous dust can be reduced by seal to enter between lock tube and female joint, while is decreased extraneous dust and entered peace
In dress hole and paste on ball, and can prevent extraneous dust from being entered by mounting hole on the medial surface of female joint, carry
The dust-proof effect of high hydraulic quick coupling.On the other hand, during lock tube slides, because the outside portion of seal can be
Slided on the medial surface of lock tube or the inside portion of seal can be slided on the lateral surface of female joint, be i.e. seal can be with
The relative slip of lock tube or seal can slide in female joint together with lock tube so that the setting of seal will not make lock tube
It is stuck in female joint, slip of the lock tube in female joint will not be influenceed by seal., can and seal is flexible
Abut in the inner side of lock tube all the time to ensure the inside portion of the outside portion of seal or seal during lock tube slides
On the lateral surface of face or female joint, so as to reduce the entrance of dust, the dust-proof effect of hydraulic quick coupling is improved.This hydraulic pressure is fast
Quick coupling can not only ensure that slip unaffected and can of the lock tube in female joint enough improves the dust-proof effect of hydraulic quick coupling
Fruit.
In above-mentioned hydraulic quick coupling, one end of the lock tube is keyed end, is set on the medial surface of the keyed end
It is equipped with a ring convex for being used to block the baffle ring of mounting hole, protrusion being additionally provided with the medial surface of the keyed end in a ring
Ring, the bulge loop are located at the outer end of baffle ring, have annular groove between baffle ring and bulge loop on the medial surface of the keyed end.
When needing the ball to be moved in mounting hole, sliping off lock tube makes baffle ring no longer block mounting hole, and makes the outer of mounting hole
Port and annular groove face, the outer end of ball can be entered in annular groove；Then lock tube is pushed back, baffle ring promotes ball to make ball
Return in mounting hole, baffle ring shelters from mounting hole and is limited in ball in mounting hole again.
Bulge loop and annular groove can prevent lock tube ball during slip from dropping out or directly contacting outer out of lock tube
Dust in boundary's air, reduce extraneous dust and paste on ball；Bulge loop is arranged on the outer end of baffle ring, and bulge loop more leans on than baffle ring
The end face of nearly keyed end, bulge loop can reduce dust and be entered from keyed end between lock tube and female joint, while decrease outer
Boundary's dust is entered into mounting hole and pasted on ball, so as to improve the dust-proof effect of hydraulic quick coupling.
In above-mentioned hydraulic quick coupling, the other end of the lock tube is dust-break end, on the medial surface at the dust-break end
The collar of protrusion is fixed with, the projection in a ring of protrusion is provided with the lateral surface of the female joint, it is described raised positioned at card
Between circle and baffle ring, spring is provided between the raised and baffle ring, one end of the spring is resisted against in projection, the spring
The other end be resisted against on baffle ring, the collar can be resisted against in projection.
When needing the ball to be moved in mounting hole, lock tube is set to be slided to dust-break end, spring-compressed, baffle ring no longer blocks installation
Hole, the now external port of mounting hole and annular groove face, the outer end of ball can be entered in annular groove.Lock tube is decontroled, in bullet
In the presence of spring force, baffle ring promotes ball ball is returned in mounting hole, and collar, which is resisted against in projection, makes lock tube be fixed on mother
On joint, now baffle ring shelters from mounting hole and is limited in ball in mounting hole again.
After collar, projection and spring are set, it can prevent lock tube from being taken off during being sliped off from female joint from female joint
From reduction dust is entered between lock tube and female joint, improves the dust-proof effect of hydraulic quick coupling.It is also possible to prevent to lock simultaneously
