Abstract
The utility model discloses a kind of stud provision for disengagement, including tapered sleeve, latch segment, stopping screw, described tapered sleeve top is orthohexagonal structure, bottom is cylindrical structural, tapered sleeve lower inner face is the trapezoidal hollow structure of circular cone, and tapered sleeve central upper portion is that cylindrical hollow configuration is through with lower hollow structure, and tapered sleeve lower sides is provided with the screw thread mouth run through with hollow structure inside；The bottom inner conical surface of described tapered sleeve coordinates with latch segment male cone (strobilus masculinus), and latch segment outer wall is provided with groove, groove and upper surface not through, inwall is provided with knife edge structure, and stopping screw is arranged in the screwed hole of tapered sleeve, and its head is embedded in the groove of latch segment.During dismounting, hit with a hammer tapered sleeve upper surface, tapered sleeve inner conical surface and latch segment male cone (strobilus masculinus) wedging, and the latch segment inwall edge of a knife embeds stud outer surface, now rotates the dismounting sleeve coordinated with tapered sleeve, and stud splits out from matrix.
Description
Technical field
This utility model relates to a kind of stud provision for disengagement, a kind of stud
Quick-release arrangement.
Background technology
In the maintenance process of many vehicles, the dismounting of stud becomes asking of have to solving
Topic.The particularly dismounting of high-strength large-scale stud, such as, in mine truck maintenance process
The dismounting of wheel hub stud, owing to bolt is big, equipment operating environment is severe, bolt and wheel hub
It is connected firmly, uses the bolt dismantling device of routine, be difficult to the operation of its Bolt dismantling.Existing
Having technology to disclose the device for stud dismounting, the design of its structure is not reasonable, actual
Using effect is the most not fully up to expectations.
The utility model patent of Application No. 201220516444.7 discloses a kind of stud
Provision for disengagement, it includes sleeve, wedge, rocking bar and the elastic ring support of band, and its
The inside and outside wall of type block all has on screw thread, and the inwall of lower cartridge also to be had and wedge outer surface phase
The female thread agreed with, but during long-term use, screw thread easily polishes, and overall package
Get up cumbersome, need to take a substantial amount of time, and after stud disassembles,
Stud is still engaged with the helicitic texture of provision for disengagement, wants thoroughly to unload stud
Come, must try every possible means from this provision for disengagement, screw down stud.
Utility model content
The purpose of this utility model is: provide a kind of can the dress of quick-detach stud soon
Putting, it is easy to assembly, durable in use.
The technical solution of the utility model is: a kind of stud provision for disengagement, including tapered sleeve,
Latch segment, stopping screw, it is characterised in that: described tapered sleeve top is orthohexagonal structure, under
Portion is cylindrical structural, and tapered sleeve lower inner face is the trapezoidal hollow structure of circular cone, tapered sleeve central upper portion
Through with lower hollow structure for cylindrical hollow configuration, tapered sleeve lower sides is provided with internal
The screw thread mouth that hollow structure runs through；The bottom inner conical surface of described tapered sleeve is joined with latch segment male cone (strobilus masculinus)
Closing, latch segment outer wall is provided with groove, groove and upper surface not through, inwall is provided with edge of a knife knot
Structure, stopping screw is arranged in the screwed hole of tapered sleeve, and its head is embedded in the groove of latch segment.
The cone angle of described tapered sleeve inner conical surface is 3 °～6 °, and angle is excessive, and this device is when being combined
Time, in latch segment, male cone (strobilus masculinus) easily spins, it is impossible to self-locking or locking function are the best；Angle mistake
Little, though the locking function of this device is good, but can be difficult to after stud takes out from matrix from
Device ejects or needs the biggest impulsive force to be ejected.
Described latch segment is equally distributed 2～4 pieces.
The number of described stopping screw (3) is consistent with the number of latch segment (2).
Inside after the combination of described latch segment is hollow cylindrical structure.
Beneficial aspects of the present utility model is: during dismounting, and hit with a hammer tapered sleeve upper surface,
Tapered sleeve inner conical surface and latch segment male cone (strobilus masculinus) wedging, the latch segment inwall edge of a knife embeds stud appearance
Face, now rotates the dismounting sleeve coordinated with tapered sleeve, and stud splits out from matrix, lock
Tight block without departing from tapered sleeve, remains in tapered sleeve under stopping screw effect, convenient second time
Use, simple in construction, flexible and convenient to use.Meanwhile, this device be by tap rather than
Threaded engagement is fixed, and its service life is long.
Accompanying drawing explanation
Fig. 1: stud provision for disengagement sectional view
Fig. 2: stud provision for disengagement upward view
In figure: 1 tapered sleeve, 2 latch segments, 3 stopping screws, 4 studs, 5 knife edge structures.
Detailed description of the invention
A kind of stud provision for disengagement, including tapered sleeve, latch segment, stopping screw, described cone
Set top is orthohexagonal structure, and bottom is cylindrical structural, and tapered sleeve lower inner face is circular cone ladder
Shape hollow structure, tapered sleeve central upper portion is that cylindrical hollow configuration is through with lower hollow structure,
Tapered sleeve lower sides is provided with the screw thread mouth run through with hollow structure inside；The bottom of described tapered sleeve
Inner conical surface coordinates with latch segment male cone (strobilus masculinus), and latch segment outer wall is provided with groove, groove and upper surface
Not through, inwall is provided with knife edge structure, and stopping screw is arranged in the screwed hole of tapered sleeve, its head
Portion is embedded in the groove of latch segment.The purpose arranging knife edge structure is to make stud card
On the knife edge structure of latch segment, so reduce the contact surface of latch segment and stud, really
Protect while possessing required frictional force, prevent because contact surface is excessive and stuck.
The cone angle of described tapered sleeve inner conical surface is 3 °～6 °, and angle is excessive, and this device is when being combined
Time, in latch segment, male cone (strobilus masculinus) easily spins, it is impossible to self-locking or locking function are the best；Angle mistake
Little, though the locking function of this device is good, but can be difficult to after stud takes out from matrix from
Device ejects or needs the biggest impulsive force to be ejected.
Described latch segment is equally distributed 2～4 pieces.
Inside after the combination of described latch segment is hollow cylindrical structure.
During use, first that each unit construction is good, and it is fixed in one end of stud, Gu
Method of determining uses hammering to be fixed on stud, after fastening, uses and overlaps jacket casing accordingly
Live the top of tapered sleeve, then provision for disengagement is disassembled together with stud.
If desired the stud after dismounting is unloaded down from provision for disengagement, only need to use fixture
Provision for disengagement is fixed, then uses the steel pricker circular hole from tapered sleeve top to be inserted into, then pass through
Stud is ejected by hammering steel pricker, it is noted that the external diameter of the steel pricker of use should be less than tapered sleeve top
The diameter of circular hole, otherwise there will be steel pricker and is stuck in provision for disengagement, cause provision for disengagement to scrap.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned explanation
Holding, relevant staff completely can be in the scope without departing from this utility model technological thought
In, carry out various change and amendment.The technical scope of this utility model is not limited to
Content in description, it is necessary to determine its technical scope according to right.
