Description
Technical field
The utility model is related to Automatic manual transmission fields, and in particular to a kind of spring-loaded plunger locking type Quick Release pin.
Background technology
With advances in technology and people increase the demand of petroleum resources, the construction party of marine drilling riser
Formula increasingly tends to use diesel hammer piling work, and what drilling well used piling work hammers formula marine riser as outer flat structure,
When offshore oil development operation carries out product lifting, the special elevator ring that designs is used cooperatively with its conventional elevator, and elevator ring is two
Semi-ring is constituted, and two semi-rings are connected using axis pin, and original axis pin is plain bolt, and when use needs regular dismounting, Bolt dismantling
During often collide with, screw thread is regular to be damaged, and is influenced the cooperation of bolts and nuts, is led to onsite application
Often there is the case where nut is difficult to be screwed into or be difficult to dismantle in process, and the use of elevator ring needs working at height, operation people
Member is frequently necessary to singlehanded operation, not only inconvenient but also dangerous.
Invention content
To overcome the deficiencies of existing technologies, the utility model provides a kind of spring-loaded plunger locking type Quick Release pin, it is ensured that quickly
Dismounting, it is swift and convenient to operate, securely and reliably, joint efficiency is further increased, reduces task difficulty.
The technical scheme adopted by the utility model is that：A kind of spring-loaded plunger locking type Quick Release pin, including axis pin and locking cap,
The axis pin upper end vehicle annular groove, lead angle under the vehicle of annular groove lower face, lead angle on the vehicle of axis pin upper surface, the locking cap axially bore
Circular hole is matched with axis pin, radial to bore big locking hole and small locking hole, and locking device includes spring catch, spring, draw ring hole and draw ring,
The spring catch butt end is matched with big locking hole, and taper end is matched with small locking hole, and spring is placed on spring catch taper end, and spring catch is logical
Draw ring hole is crossed to connect with draw ring.
Above-mentioned technical proposal can advanced optimize for：
The spring catch material is structural alloy steel.
The spring materials are stainless steel.
The locking cap material is carbon constructional quality steel.
The beneficial effects of the utility model are：Spring-loaded plunger locking type Quick Release pin provided by the utility model, passes through locking
Device and axis pin, locking cap quick locking with detach, it is ensured that fast assembling-disassembling, it is swift and convenient to operate, securely and reliably, further carry
High joint efficiency reduces task difficulty.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is pin shaft structure schematic diagram.
Fig. 3 is locking cap structural schematic diagram.
Fig. 4 is spring catch structural schematic diagram.
Fig. 5 is spring and pull ring structure schematic diagram.
In figure：1- axis pins, 2- locking caps, the big locking holes of 21-, 22- circular holes, the small locking holes of 23-, 3- annular grooves are led on 4-
Angle, 5- locking devices, 51- spring catch, 52- springs, 53- draw rings hole, 54- draw rings, lead angle under 6-.
Specific implementation mode
By spring pocket in 51 taper end of spring catch, which passes sequentially through the big locking hole 21 of locking cap 2 and small
After locking hole 23, draw ring 54 is connected with spring catch 51 by draw ring hole, is equipped with spring catch 51, the locking cap 2 of spring 52 is placed in
It on axis pin 1, when upper lead angle 4 is passed through in 2 lower end of locking cap downwards, is moved outside spring catch 51, spring 52, which is pressurized, to be shunk, locking cap 2
When annular groove 3, lower lead angle 6 are passed through in lower end downwards, the interior shifting under the elastic force effect of spring 52 of spring catch 51,51 butt end of spring catch
Into in annular groove 3, annular groove 3 to spring catch 51 limit up and down, at this point, plunger is locked under the elastic force effect of spring 52
Formula Quick Release pin is in locking state；When preparing to dismantle plunger locking type Quick Release pin, lifts draw ring 54 and stretch out, when the stretching
Power be more than spring 52 elastic force when, 51 butt end pressuring spring 52 of spring catch is simultaneously displaced outwardly, when be moved to be detached from 3 shape of annular groove
When state, plunger locking type Quick Release pin locks status releasing, at this point, holding draw ring 54 and being lifted up locking cap 2, with axis pin 1
Separation, to realize fast quick-detach.
In a preferred embodiment, 51 material of spring catch is structural alloy steel, and 52 material of spring is stainless steel, locking cap 2
Material is carbon constructional quality steel.
