Description
Technical field
Sleeve technical field is the utility model is related to, is specially a kind of just dismounting locking sleeve.
Background technology
Existing expansion link realizes the function of releasing and lock more by the way of bolt or torque spring, is stretched in regulation
Particular tool is generally required during the length of contracting bar to remove and install, reduces disassembly efficiency, also, the locking device on expansion link
Under long-term use, because abrasion can make locking device can not fasten expansion link, expansion link is caused to release so as to be installed on flexible
Product on bar is possible to damage or even injure by a crashing object people, brings potential safety hazard.The power transmission shaft of locking device is provided with 4 bearings,
Positioned with 4 sleeves.According to the positioning principle of sleeve, during locking nut screwing, locking nut extruding bearing, so that
Relative displacement occurs between bearing and sleeve, displacement is bigger, and the effect of tightening is better, so theoretically this assembling shape
Formula is capable of the position of effectively fixing bearing.But when locking nut is screwed into place, the small of bearing bore diameter corrects and sleeve
Conical surface small end aligns, and now locking nut can not continue to be screwed into, and bearing again can not be to the big end motion of sleeve, so just
Bearing can not be more fully fastened, then just there occurs axial float.

The problem of going out.
To achieve the above object, the utility model provides following technical scheme：It is a kind of just to dismantle locking sleeve, bag
Include：Expansion link, taper tightening sleeve and sleeve body, the sleeve body are nested in the taper tightening sleeve inner,
It is arranged in the sleeve body to the coaxial break-through of expansion link, the expansion link is radially inside provided with slide bar, described
Taper tightening sleeve periphery is enclosed with dismounting oil pocket, and the dismounting oil pocket upper surface is provided with oil pocket mouth, the expansion link lower end
Socket end is installed, the dismounting oil pocket side outer face is provided with clamping section, and the clamping section side is connected with U-shaped breach,
The dismounting oil pocket opposite side outer face is provided with lock sleeve, and the dismounting oil pocket bottom is provided with disconnecting prevention structure, the anticreep
Hoop is provided with structure, taper face is provided with the sleeve body, the taper face lower end is provided with escape, institute
State and be provided with screw thread below sleeve body.
Preferably, the oil pocket mouth is provided with several, and its inner side is provided with the fillet of screw, is easy to device efficiently to enter
Oil, and it is easy to external device (ED) to close oil pocket mouth.
Preferably, the slide bar is provided with several, improves operating efficiency.
Preferably, the hoop is movably connected on the disconnecting prevention structure by screw, can easily be adjusted at any time
The angle of sleeve with it is elastic.
Preferably, the escape is curved, is easy to device more easily to work.
Preferably, the taper tightening sleeve inner face is provided with one layer of slipmat, prevents coming off for sleeve, improves dress
The operating efficiency put.
Preferably, the disconnecting prevention structure is provided with 2, the anticreep effect of stiffening device.
Compared with prior art, the beneficial effects of the utility model are as follows：
1st, the utility model product ensures that external device (ED) such as locking nut can continue to toward this reality by the escape of setting
It is screwed into new bigger diameter end, so as to reach more preferable fastening effect, prevents power transmission shaft from axial float occurs, reduces equipment dimension
Number is repaiied, reduces maintenance cost and cost.
2nd, the utility model can be when sleeve needs dismounting by the dismounting oil pocket of setting, will not be because of device
The crimp of internal part and can not conveniently dismantle, and the tightening in locking device can be packed into by the expansion link of setting
The movement that line position is put, can meet the needs of people, operating efficiency is high, and cost is low, is adapted to a wide range of production of factory, is applied to
Each production field.
