Cooperation causes, stud processing request height high to fraising dimension precision requirement, installation process complexity, installation time-consuming and laborious.
2) hydraulic bolt composition generally comprises: stud, sleeve, nut and auxiliary installer material, by stud and
Hydraulic oil pressurization is between sleeve with expansion sleeve, and then fits closely sleeve and connection holes and play anastomosis；Hydraulic bolt
Installing and dismounting needs the frock tools such as dedicated hydraulic pump, and installing and dismounting is complicated, the installing and dismounting space of needs is big, for narrow
The normal not qualified to exploit in installation position.
3) hydraulic bolt sleeve and traditional reamer bolt all need accurately to be processed according to coupling bolt hole, lead to connector
Interchangeability it is poor, repairing open and inspect damage after be also required to be remake according to pore size, the period is longer.
Summary of the invention
In view of this, the present invention provides a kind of fast assembling-disassembling fastener, it can effectively solve the problem that existing bolt fastener exists
Couple it is time-consuming and laborious, need to dismount space is big, repair in fastener the problems such as need to remaking.
The fast assembling-disassembling fastener includes: taper stud, nut, stop washer and subdivision taper sleeve component；
The taper stud includes the conical section for being machined with externally threaded thread segment and small end and connecting with the thread segment；
The subdivision taper sleeve component includes the subdivision tapered sleeve of more than two arcs, and the inner surface of the subdivision taper sleeve component is
With the matched tapered surface of taper stud conical section；
In use, the conical section of the taper stud is located in the connecting hole of component to be tightened, more than two arcs
Subdivision tapered sleeve be sleeved in the annular space between the taper stud and the component connecting hole to be tightened, and circumferentially divide
Cloth forms a ring structure, there is gap between two neighboring subdivision tapered sleeve, subdivision tapered sleeve and join component connecting hole to be tightened it
Between have gap；The thread segment of the nut and the taper stud is threadedly engaged；In the subdivision taper sleeve component and the nut
The end of opposite end carries out axial limiting by the stop washer.
The stop washer is threaded on the component to be tightened.
The subdivision taper sleeve component includes the subdivision tapered sleeve of three arcs.
The utility model has the advantages that
Using fastener of the invention, subdivision bush assembly, taper stud, stop washer etc. can be all in connecting component
One end operation, when installation, required operating space was much smaller than traditional fitting-up bolt or hydraulic bolt, and it is practical to solve existing engineering
Middle connection is time-consuming and laborious, it is big to need to dismount space, repair in fastener the problems such as need to remaking, substantially reduce construction week
Phase.The fast assembling-disassembling fastener in small space may be implemented in the present invention, greatly shortens construction period, reduces construction work amount.

Specific embodiment
With reference to the accompanying drawings and examples, the present invention is described in further detail.
The present embodiment provides a kind of fastener of fast demountable that can be used in small space, component to be tightened is connection
Acting flange 5.
As shown in Figure 1, the fastener includes taper stud 1, nut 2, stop washer 3 and subdivision taper sleeve component 4.
As shown in Fig. 2, 1 one end of taper stud is machined with external screw thread (as threaded connection section), the outer circumference surface of the other end
For the conical surface (i.e. conical section), and the small end of the conical surface is connected with externally threaded one end is machined with.
As shown in figure 3,3 excircle of stop washer is machined with external screw thread, 5 end face annular groove of screw thread specification and connection flange
The internal screw thread specification of inner peripheral surface is identical, and stop washer 3 plays limitation subdivision tapered sleeve group by being threaded into connection flange 5
The effect that part 4 moves axially.
As shown in figure 4, subdivision taper sleeve component 4 includes the subdivision tapered sleeve 6 of three arcs, the inner surface of subdivision taper sleeve component 4
With the matching of the outer surface of 1 conical section of taper stud (i.e. the two taper is identical).
When using the fastener, the conical section of taper stud 1 is first protruded into connection flange 5 from one end of connection flange 5
In centre bore, the annular that then three subdivision tapered sleeves 6 are sleeved between 1 outside of taper stud and 5 centre bore of connection flange is empty
In, three subdivision tapered sleeves 6, one ring structure of circumferentially distributed is formationed, there are between centainly between two neighboring subdivision tapered sleeve 6
Gap, and there are certain interval between 4 excircle of subdivision taper sleeve component and the centre bore of connection flange 5, this special designing can be with
Guarantee that taper stud, subdivision taper sleeve component can be dismounted from the either side of connection flange 5, facilitates installation, disassembly.Then in taper
Stop washer 3 is set on stud 1, stop washer 3 is threadedly coupled with connection flange 5, carries out axial limit to subdivision taper sleeve component 4
Position；Nut 2 is finally threaded in the thread segment of taper stud 1, after nut 2, which is moved to, to be contradicted with stop washer 3, is continued
Nut 2 is tightened, so that taper stud 1 moves axially under the torque effect of nut 2, due to taper stud 1 and subdivision tapered sleeve group
Part 4 is cone match, so that radial forces are generated on subdivision taper sleeve component 4, so that subdivision taper sleeve component 4 expands,
It is fitted closely with the centre bore of connection flange 5, to play anastomosis.
Ten parts of the fastener application range extensively, can be applied to connection, large size between ship domain drive shaft system flange and set
Standby host foot fixation etc., can be used for the tradition machineries industry such as chemical industry, petroleum, electric power, for example the large scale equipments such as generator fixation etc..
To sum up, the above is merely preferred embodiments of the present invention, it is not intended to limit the scope of the present invention.It is all
Within the spirit and principles in the present invention, any modification, equivalent replacement, improvement and so on should be included in protection of the invention
Within the scope of.
