Description
Technical field
The utility model relates to the technical fields of dilator, should more particularly, to a kind of cold shrink sleeve extension fixture and application
The dilator of device.
Background technique
Cold shrink tube generally refers to Cold-contraction cable accessory.Cold-contraction cable accessory is (common using elastomeric material
Have silicon rubber and EP rubbers) inject sulfidization molding in factory, then through it is expanding, be lined with plastic spiral supporter constitute it is various
The component of cable accessory.When in-site installation, by these predilation parts cover after treatment cable end piece or joint, extraction
The plastic spiral item (supporter) of inside support, be pressed on cable insulation and the cable accessory that constitutes.Because it is in room temperature
Elastic recovery force is leaned on down, rather than as being heat-shrinked the fiery heat shrink of cable accessory, therefore it is commonly called as cold events cable accessory.In early days
Cold events cable terminal be superinsulation using silicon rubber shrinkage component, electric field treatment still uses stress cone pattern or answers
Power band is around packet mode.
Authorization Notice No. CN103042686B Chinese patent discloses a kind of high-voltage electricity solenoid steel wire expanding machine comprising expands
Mechanism, power source mechanism and control device are opened, the power source mechanism drives expanding mechanism work for driving expanding mechanism
Make, for the control device for controlling power source mechanism, the cold pipe fixing piece includes be connected to expanding bar front end cold
Pipe sleeve bar, the cold pipe sleeve bar front end sleeve are equipped with mold core head, the tapered structure of mold core head.
Prior art among the above has the following deficiencies: that the front end of cold shrink sleeve is arranged in mold core head, and mold core head needs
Mold core head is fallen in order to prevent when bouncing back, and operator will help always mold core head during mold core head bounces back, still
When mold core head bounces back, periphery is that steel wire is likely to stab the hand of operator entirely, this problems demand solves.
Utility model content
The purpose of this utility model one is to provide a kind of extension fixture, with stent core print, saves mold core head and is returning
Manpower helps the movement of mold core head during contracting.
To achieve the above object, the utility model provides following technical solution:
A kind of extension fixture, including propulsion tube, the end of the propulsion tube direction of propulsion are detachably provided with mold core head, institute
The one end for stating propulsion tube contact mold core head, which is provided with, wears column, and one end of the mold core head contact propulsion tube is provided with overlap aperture,
The overlap aperture inner sidewall offers sliding groove, and card slot, the card is arranged far from one end of propulsion tube in the overlap aperture inner sidewall
Slot is connected to sliding groove；The column lateral wall that wears is provided with the fixture block being fastened in card slot.
By using above-mentioned technical proposal, when needing to expand cold shrink tube, need mold core head being fixed on propulsion tube end, this
Shi Yaoxian will wear column and be threaded through in overlap aperture, and fixture block is directed at sliding groove and is inserted into sliding groove, then when fixture block to Dacca
When the position of slot, fixture block is caught in card slot by rotation mold core head, and mold core head is not in the case where being parallel to the active force for wearing column at this time
It can be fallen down from propulsion tube, therefore mold core head is fixed on when bouncing back on propulsion tube, is not needed the hand steered of operator and is held
Mold core head, thus play the role of protect operator.
Further, the sliding groove is close to one end of propulsion tube in opening setting, and the opening of the sliding groove is in
Angle setting.
By using above-mentioned technical proposal, the chamfering of the sliding groove opening after chamfering increases sliding groove to a certain extent
The width of opening, fixture block at this time enter more convenient in sliding groove, and mold core head is fixed on propulsion tube to play and facilitate
On effect.
Further, the overlap aperture bottom wall opens up telescopic hole, and sliding is provided with conflict and wears column in the telescopic hole
Conflict block, the conflict block are provided with spring far from wear column on one side.
By using above-mentioned technical proposal, when wear column wear set in overlap aperture when, wear one of column far from mold core head
End contradicts in conflict block, and spring is driven to compress in telescopic hole, and when the hand of operator is decontroled, spring drives conflict block
Conflict wears column, while wearing column and fixture block is driven to contradict the side wall of card slot, thus increase the frictional force between card slot and fixture block, into
And play the role of that mold core head is further prevented to fall off from propulsion tube.
Further, the described one end of mold core head far from propulsion tube is arranged in the angle of falling ball.
By using above-mentioned technical proposal, original tapered setting of mold core head, the relatively narrow end of mold core head is likely to pair
Operator causes to damage, and the mold core head behind the angle of falling ball, and the area of end touch operation personnel increases, touch operation personnel couple
The pressure that operator generates reduces, to play a part of to protect operator.
The purpose of this utility model two is to provide a kind of cold shrink sleeve dilator, and tool facilitates operator to expand shrinkage set
The effect of pipe.
To achieve the above object, the utility model provides following technical solution:
A kind of dilator further includes the work that frame puts extension fixture using the dilator of above-mentioned cold shrink sleeve extension fixture
Platform, the workbench are disposed with placement plate and expansion plate along the both ends of propulsion tube moving direction, on the expansion plate
Offer the advancement holes flexible for mold core head and propulsion tube, a structure of an essay for the expansion plate and placement plate is placed with slide bar, the slide bar
Upper sliding is provided with expansion board, and steel wire is provided on the expansion board, and the steel wire is arranged along propulsion tube length direction, and described
Steel wire is threaded through in advancement holes.
By using above-mentioned technical proposal, when needing to expand cold shrink sleeve, steel wire is gathered together, cold shrink sleeve is worn
It is located on the steel wire to gather together, then pushes propulsion tube, propulsion tube band moving-mould-core head is mobile, and mold core head drives steel wire to expand
, cold shrink sleeve is expanded by steel wire and propulsion tube, to play the role of facilitating expansion cold shrink sleeve.
Further, mold core head contact steel wire is provided with recessing groove on one side.
By using above-mentioned technical proposal, when being inserted between cold shrink sleeve, directly contact cold shrink sleeve is mold core head
Steel wire between cold shrink sleeve and mold core head, for steel wire protrusion on the surface of mold core head, the area that steel wire contacts cold shrink sleeve is small, right
The pressure of cold shrink sleeve is big, it is likely that cold shrink sleeve caused to damage, and recessing groove can allow steel wire recess in recessing groove, it will not
Make the surface of steel wire protrusion mold core head, to play the role of protecting cold shrink sleeve.
In conclusion the advantageous effects of the utility model are as follows:
1, fixture block, sliding groove and card slot are used, operator personnel support is not needed when to generating retraction mold core head
Effect；
2, taking and placing slot is used, to generate the effect of mold core head easy to disassemble；
