Abstract
The utility model relates to a dismounting device, in particular to obturating cup dismounting device. Dismounting device include collet (1), casing (2) and thimble (3), the one end in casing (2) is fixed in collet (1), open along the axial collet (1) and casing (2) has the through -hole, collet (1) be the cylinder, the hole tip has tapered to it has logical groove to open along the axial on this tip outer wall, and thimble (3) have tapered cylinder of complex in with for one end, install in casing (2) through threaded connection. The device easy operation screws up and pulls the handle behind the thimble and can extract the obturating cup from the casing, moreover in the use this device not with casing direct contact, so can not cause the damage to the casing.
Description
Technical field
This utility model relates to a kind of provision for disengagement, particularly to a kind of obturating cup provision for disengagement。
Background technology
Existing a lot of hydraulic tests can be used the internal obturating cup with steel ring, dismounting obturating cup often uses screwdriver or cleek to be prized before, this operational approach wastes time and energy, and this type of sharp instruments is also easy to scratch housing, it is thus desirable to design is a kind of easy to operate, and safe and reliable extracting tool。
Summary of the invention
This utility model solve the technical problem that into: a kind of efficiently dismounting and the provision for disengagement that obturating cup damage is less are provided。
The technical solution of the utility model is: described provision for disengagement includes collet 1, housing 2 and thimble 3, collet 1 is fixed on one end of housing 2, collet 1 and housing 2 have through hole vertically, collet 1 is cylindrical shape, interior bore ends is with tapered, and this end outer wall has groove vertically, thimble 3 be one end with the tapered cylinder with inner cone positive, be threaded connection and be arranged in housing 2。
As a kind of improvement of the technical program, collet 1 is spring steel material。
As a kind of improvement of the technical program, the periphery of collet 1 outer end has cross knurled。
The beneficial effects of the utility model are: simple to operate, and pulling handle after tightening thimble can extract obturating cup from housing, and in use procedure, this device does not directly contact with housing, so housing will not be caused damage。
Accompanying drawing explanation
Fig. 1 is: structural representation of the present utility model；
Fig. 2 is: this A-A sectional view；
Fig. 3 is: the enlarged drawing of B；
In figure: 1 is collet, 2 is housing, and 3 is thimble, and 4 is obturating cup housing, and 5 is obturating cup。
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical program is described in further detail。
A kind of obturating cup provision for disengagement, it is characterised in that include collet 1, housing 2 and thimble 3。Collet 1 and housing 2 are fixed together by screw thread, thimble 3 and housing 2 pass through threaded engagement, thimble 3 can be made to occur to move forward and backward by rotating thimble 3, then promote collet 1 to expand when thimble 3 moves forward, even with the frictional force produced after the expansion of collet 1 and between obturating cup 5 inner ring, obturating cup 5 is extracted from obturating cup housing 4 time actually used。This compact conformation, easy to use, and also in unloading process, provision for disengagement will not directly contact with obturating cup housing 4, thus effectively reducing the probability scratching obturating cup housing 4 in unloading process。
During dismounting obturating cup, first the head of this frock is stretched in the inner ring of obturating cup, then tighten thimble clockwise, make collet expand, pull housing subsequently and obturating cup is extracted from housing。
Referring to Fig. 1, by rotating thimble 3, then collet 1 can be strutted by the conical surface of thimble 3 head, thus being in close contact with obturating cup steel ring inner circle, thus utilizing frictional force to be extracted by obturating cup。
Operation principle of the present utility model is:
As it is shown in figure 1, collet 1 Front-end Design concave inward structure, avoiding the projection in the middle of obturating cup cleverly, the external cylindrical surface partial design that collet 1 front end contacts with obturating cup becomes hatching knurling, effectively enhance frictional force。Thimble 3 head design becomes low-angle cone structure, collet 1 is internal is also designed to low-angle cone structure, when firmly tightening thimble 3, extruding mutually between two conical surfaces makes to produce on collet 1 powerful tension force, is split out by obturating cup exactly because there being big tension force could produce enough frictional force。
Claims (3)
1. an obturating cup provision for disengagement, it is characterized by: described provision for disengagement includes collet (1), housing (2) and thimble (3), collet (1) is fixed on one end of housing (2), collet (1) and housing (2) have through hole vertically, collet (1) is cylindrical shape, interior bore ends is with tapered, and this end outer wall has groove vertically, thimble (3) with the tapered cylinder with inner cone positive for one end, is threaded connection and is arranged in housing (2)。
