Utility model content
The purpose of utility model：Given up to provide a kind of more preferable coiled tubing General hydraulic of effect, specific purposes are shown in
Multiple substantial technological effects of part are embodied.
In order to reach as above purpose, the utility model adopts the following technical scheme that：
Coiled tubing General hydraulic is given up, it is characterised in that and comprising top connection, top connection is connected to an outer wall section,
Top connection inwall includes a ball seat, and the ball seat is tubular, and its inwall can accept a ball, and ball seat can be suitable under the impact of ball
Outer wall section to move inside outer wall section, a claw sliding sleeve is connected to by shear pin on outer wall section, the claw is slided
Putting and include groove, claw sliding sleeve presses a closing piece, and projection is included on the closing piece, and outer wall section avris is lower contact,
Closing piece presses lower contact, and when ball seat promotes claw sliding sleeve to slide, the recessed of claw sliding sleeve can be slided into below closing piece
The locking to lower contact is further decontroled in groove further such that outer wall section and the relative slippage of lower contact.
The further technical scheme of the utility model is, cutting ferrule, cutting ferrule are connected to by compression spring below the ball seat
It is close to claw sliding sleeve.
The further technical scheme of the utility model is, includes a hole on the outer wall section, and the projection on closing piece is worn
Lower contact is pushed against after crossing the hole.
The further technical scheme of the utility model is that the projection on the closing piece includes three.
The further technical scheme of the utility model is, includes groove on the lower contact inwall, closing piece it is raised and recessed
Groove agrees with.
Using the utility model of as above technical scheme, had the advantages that relative to prior art：The process used
In, when entering well tool string by card, steel ball is put into from top to bottom, and ball seat is under the impact of ball, and shear pin fracture, ball seat can be along outer
Wall part is moved inside outer wall section, and when ball seat promotes claw sliding sleeve to slide, claw can be slided into below closing piece
The locking to lower contact is further decontroled in the groove of sliding sleeve further such that outer wall section and lower contact slip relatively, further
Lower contact is abandoned in underground, other objects can pull out.

Embodiment
With reference to the accompanying drawings and detailed description, the utility model is furtherd elucidate, it should be understood that following specific embodiment parties
Formula is merely to illustrate the utility model rather than limitation the scope of the utility model.It should be noted that make below in description
Word "front", "rear", "left", "right", "up" and "down" refer to the direction in accompanying drawing, and word " interior " and " outer " refer to respectively
Be directed towards or the direction away from particular elements geometric centers.
Coiled tubing General hydraulic is given up, it is characterised in that and comprising top connection, top connection is connected to an outer wall section,
Top connection inwall includes a ball seat, and the ball seat is tubular, and its inwall can accept a ball, and ball seat can be suitable under the impact of ball
Outer wall section to move inside outer wall section, a claw sliding sleeve is connected to by shear pin on outer wall section, the claw is slided
Putting and include groove, claw sliding sleeve presses a closing piece, and projection is included on the closing piece, and outer wall section avris is lower contact,
Closing piece presses lower contact, and when ball seat promotes claw sliding sleeve to slide, the recessed of claw sliding sleeve can be slided into below closing piece
The locking to lower contact is further decontroled in groove further such that outer wall section and the relative slippage of lower contact.The technical scheme at this place
The substantive technique effect and its implementation process played is as follows：During use, when entering well tool string by card, from upper
Steel ball is down put into, under the impact of ball, shear pin fracture, ball seat can move ball seat along outer wall section inside outer wall section,
When ball seat promotes claw sliding sleeve to slide, it can slide into below closing piece in the groove of claw sliding sleeve and further decontrol under
The locking of joint is further such that outer wall section and the relative slippage of lower contact, further abandon lower contact in underground, other objects
It can pull out.Realization is conveniently given up, and reduces loss.
Cutting ferrule is preferably connected to by compression spring below the ball seat as further, cutting ferrule is close to claw cunning
Set.The substantive technique effect and its implementation process that the technical scheme at this place is played are as follows：The compression spring and card at this place
The played effect of set is, when in work progress, because liquid in pipe pressure oscillation is impacted to claw sliding sleeve, and shear pin stress,
It is that can play cushioning effect using spring, cushioning effect is avoided that in it ensures instrument before non-pitching under impact load
It is in good condition.
Include a hole on the outer wall section, the projection on closing piece pushes against lower contact after passing through the hole.Using this place
Structure, can relative positioning closing piece position.
Projection on the closing piece includes three.As illustrated, three projections can extrude it is more closely knit.
Groove is included on the lower contact inwall, the projection and groove of closing piece are agreed with.What the technical scheme at this place was played
The technique effect and its implementation process of essence are as follows：Agree with and be shaped such that the effect of locking is more preferable, after closing piece gets off, energy
Smoothly slide.
In a creative way, each effect of the above is individually present, moreover it is possible to the combination of the above results is completed with a nested structure.
It is clear that the technique effect that above structure is realized is realized, discounting for additional technical scheme, this patent title is also
It can be apparatus under a kind of oil well.Part details not shown in figure.
It should be noted that multiple schemes that this patent provides include the basic scheme of itself, independently of each other, not mutually
Restrict, but it can also be mutually combined in the case where not conflicting, and reach multiple effects and realize jointly.
The advantages of general principle of the present utility model, principal character and the utility model has been shown and described above.Ability
The technical staff in domain should be recognized that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model can also
There are various changes and modifications, these changes and improvements are both fallen within claimed scope.
