Abstract
The invention belongs to Automatic manual transmission field, and in particular to a kind of from rebound fastener.Fastener at deep hole generally relies on the magnetism between spanner and fastener or suction-operated when taking out.The rebound fastener certainly of the present invention, including fastener, sleeve, spring and base with through hole, described sleeve one end is band hole end surface, another end opening, fastener, spring and base are fitted into sleeve from openend successively, base is connected in opening and sleeve, and spring is spacing by the head of fastener and base.Solve the problems, such as that disassembly of fastener at deep hole, taking-up, connector separate inconvenience with connected compcnent.
Description
Technical field
The invention belongs to Automatic manual transmission field, and in particular to a kind of from rebound fastener.
Background technology
When fastener in deep hole is attached, is dismantled, it is deep into hole and carries out usually using stock allen wrench
Operation.Operating personnel can not see dismounting situation in most cases, it is impossible to which whether accurate judgement fastener is dismantled in place.Deep hole
The fastener at place generally relies on the magnetism between spanner and fastener or suction-operated when taking out, this method be adapted to size,
The small connector of weight.And then there is the magnetic or hypodynamic phenomenon of suction-operated for the larger connector of size, weight.
In the case of not taking out fastener completely, separation connector is with that need to consider fastener extension, connector point during connected compcnent
Opening certain distance could complete to dismantle.
In place whether therefore, it is necessary to a kind of fastener of special construction, operating personnel can be made to perceive dismounting and, conveniently taken
Go out, and can be convenient to separate connector and connected compcnent in the case where not taking out.
The content of the invention
The technical problems to be solved by the invention are the dismountings for deep hole internal clamp, in situation about can not directly observe
Under, can easily it take out.
The present invention's includes sleeve, four part of spring, base and fastener, head of the spring in fastener from rebound fastener
Between portion and base, play the role of making fastener rebound, i.e. remote base in the case of compression.The port of base and sleeve
It is fixedly connected, it is on the one hand spacing to one end of spring, play protection spring and do not fall off, on the other hand play the role of packing ring；Set
Cylinder plays the role of encapsulating fastener, spring and base in outermost, and control fastener snap-off-distance, avoid fastener with
Spring departs from.
The structure that the present invention can be combined by designing a kind of sleeve, spring, base and General fasteners, solves tight at deep hole
The problem of firmware dismounting, taking-up, connector separate inconvenience with connected compcnent.
Brief description of the drawings
Fig. 1 is structure diagram of the present invention from rebound fastener；
Fig. 2 is working state schematic representation of the present invention from rebound fastener.
Embodiment
The present invention program is further described below with reference to attached drawing.
Spring 2 is inserted in the bar portion of fastener 4, base 3 is inserted in the end of fastener 4, it is overall to be fitted into sleeve 1, cover
Cylinder 1 is fixed in port and base 3, and wherein spring 2 subtracts base from size L under external force state equal to fastener spiro rod length l
Height H, i.e. L=l-H, inner surface top and distance d, d the ＜ H on 4 head of fastener of sleeve 1, are shown in Fig. 1.
Working status is shown in Fig. 2, and when tightening, base 3 and spring 2 can play the role of spring washer；During dismounting, work as fastener
4 with connected compcnent 6 when separating, and fastener 4 can produce rebound phenomenon under the action of spring 2, and operating personnel can not observe
In the case of can effectively judge whether fastener 4 is dismantled in place, and at this time fastener 4 completely rebound into sleeve 1 deep hole in,
Separated easy to connector 6 with connected compcnent 5.
Claims (5)
