Form the external structure of whole device；Female connector 1 is connect with pressure cap 4, and pin end 2 is inserted in 8 lower face endoporus of cylinder body；Piston
7 are placed in 4 inner wall of pressure cap with the cavity of 8 outer wall of cylinder body, and limit slips 6 is stuck in the groove of 2 front end of pin end；Sealing ring 5 with
The connection of spring 3 is placed in the inside groove of pressure cap 4, forms reciprocating structure；During device locking, piston 7 compresses limit slips 6,
Pin end 2 is locked in cylinder body 8 by limiting 6 structure of slips.
It is a blind head that, which there are a boss, right side in 1 middle part of female connector, and right side has been distributed around a circle square hole, square hole
Both sides are equipped with seal groove, and fluid is flowed out by square hole.
The pressure cap 4 has two-stage step, first order step outer ring to be equipped with screw thread, and right side inner wall has a limited step.
The limit slips 6 is made of 15 upper limit blocks 9 and 15 elastic pieces 10, and 10 head of elastic piece is equipped with top
Limited block is rapidly feeding using the elastic deformation ability of limited block itself in the card slot of pin end body by limited block 9.
Compared with prior art, the utility model has the beneficial effects that：
1, the device is easy for installation, easy to operate, and accuracy rate is high, has certain economy.
2, network remote monitoring, high degree of automation securely and reliably can fast implement ejection escape.
3, have the function of self-closed pipeline after unlock, prevent high-pressure fluid from overflowing, pollute environment.

Fig. 3 is the structural schematic diagram for limiting slips；
Fig. 4 is the structural schematic diagram of the utility model hydraulic cylinder.
Specific implementation mode
The technical solution of the utility model is described in detail with reference to specific embodiment.
Referring to attached drawing 1-4,4 outer ring of pressure cap is matched with cylinder body 8 by helicitic texture, forms the external knot of whole device
Structure；Female connector 1 is connect with 4 upper end of pressure cap by lock-screw 11 and bolt 12, and pin end 2 is inserted in 8 lower end endoporus of cylinder body,
The runner of whole device is formed, it is a blind head that, which there are a boss, right side in 1 middle part of female connector, and right side has been distributed around a circle side
Shape hole, square hole both sides are equipped with seal groove, and fluid is flowed out by square hole；Pressure cap 4, piston 7 and cylinder body 8 form hydraulic cylinder knot
Structure, piston 7 can be axially moved under the driving of hydraulic oil, and pressure cap 4 has two-stage step, first order step outer ring to be equipped with screw thread,
Right side inner wall has a limited step；Sealing ring 5 is connect with spring 3 in the inside groove for being placed in pressure cap 4, forms reciprocating structure；Locking
State piston 7 moves right to limit on the right-right-hand limit position under hydraulic oil driving, and piston 7 compresses limit slips 6, and limit slips 6 is stuck in
The groove of 2 front end of pin end, pin end 2 is locked in cylinder body 8.Slips 6 is limited by 15 upper limit blocks 9 and 15 bullets
Property piece 10 form, 10 head of elastic piece be equipped with upper limit block 9, using the elastic deformation ability of limited block itself, by limited block
It is rapidly feeding in the card slot of pin end body.Female connector 1, spring 3 and sealing ring 5 form resetting-mechanism, and spring is compressed in mother and connects
Between first two end face and sealing ring left side, in releasing process, pin end is rapidly separated, under spring force sealing ring

Leakage
The operation principle of the utility model is as follows：
1, lock-out state
Start hydraulic control system, hydraulic pump starts the fuel feeding into hydraulic cylinder, drive of the piston 7 in hydraulic oil by hydraulic fluid port a
It moves right under dynamic, when 7 stroke of piston reaches limit on the right-right-hand limit, hydraulic pump is stopped, at this point, effect of the limit slips 6 in piston 7
Lower to lock pin end 2 in cylinder body, the inner passage of the forming apparatus of male and female connector connection at this time, fracturing fluid is through 1 end of female connector
It flows into, square hole flows into 2 inner flow passage of pin end near 1 right side of female connector, is finally flowed out by pin end 2, leads to flat
Platform well head.
2, unlocked state
Start hydraulic control system, hydraulic pump starts the fuel feeding into hydraulic cylinder, drive of the piston 7 in hydraulic oil by hydraulic fluid port b
It is moved to the left under dynamic, the radial positioning effect to limiting slips 6 is lost when piston stroke reaches certain position, at this point, public access
First 2 can shake off the effect of limit slips, and ship can leave platform, and after pin end 2 is detached from ontology, sealing ring 5 is in bullet
Spring pre-tightens to be slided to the right immediately under force effect, reaches limit on the right-right-hand limit position, 5 inner wall of sealing ring is being sealed with 1 outer wall of female connector at this time
Fluid is prevented to leak out under the action of circle.
