Abstract
The invention provides a self-locking nut which is formed by connecting a semi-through nut, an expanding screw and a hoop through reversed buckling threads. When the nut is screwed clockwise to get close to an object to force the front end of the expanding screw to abut against a baffle of an inner cavity of the semi-through nut; and meanwhile, a taper pipe of the expanding screw is completely inserted into the loop, due to the tightening effect between the taper pipe and the loop, the nut cannot be subject to buckle retreating, secondary fastening on the object is carried out even when the nut is screwed anticlockwise, the nut cannot be easily dismounted from the bolt, and therefore the functions of self locking and theft prevention are achieved.
Description
Art
The present invention relates to a kind of and plain bolt is used cooperatively, the nut that can be automatically locked.
Background technology
It is well known that for more stable fixed object, or two objects are coupled together, we are usually used screw or rivet.
Even if the former installs spring pad additional, the difficult problem for moving back button can not be still solved；And the latter has what installation was bothered and limited by execution conditions
Defect.
The content of the invention
In order to overcome above drawback, the present invention proposes a kind of energy as plain nut usage, but can be automatically locked, not move back button
Nut.The nut is made up of half logical nut, swollen silk and circular boop.
One of the technical solution adopted in the present invention is that half logical nut sets up 1 ring baffle equivalent in plain nut side, its
Internal thread is left-hand thread.
The two of the technical solution adopted in the present invention are that swollen silk is made up of pipe and conical pipe two parts, and cylindrical parts internal thread is for just
Button, external screw thread is left-hand thread；Capillary portion non-threaded, its outside is provided with shrinkage joint, and two parts total length is equal in half logical nut
Cavity length and circular boop thickness sum.
The three of the technical solution adopted in the present invention are that the external diameter of circular boop leads to the relative string of nut two less than half away from internal diameter is equal to swollen
The external diameter of silk cylindrical parts.
The four of the technical solution adopted in the present invention are, through circular boop, to be screwed to swollen silk in half logical nut, and its conical pipe is stuck in circular boop
Outward, self-locking nut is thus just constituted.
Present invention beneficial effect when in use is that it can not only be automatically locked and not move back button, it may also be necessary to continued tightly,
And and have certain anti-theft feature concurrently, rivet can be being replaced in some cases.
Description of the drawings
Further illustrate below in conjunction with the accompanying drawings.
Fig. 1 is the structure chart of the present invention；
Fig. 2 is the fundamental diagram of the present invention；
Each reference is represented respectively in accompanying drawing：(1) half logical nut, (2) are swollen silk, (3) circular boop, (4) bolt, (5) thing
Part.
Specific embodiment
As shown in Fig. 1 is left, swollen silk 2 passes through circular boop 3, is became one with left-hand thread screw thread with half logical nut 1, the taper of swollen silk 2
Pipe clamp is outside circular boop 3.
As shown in Fig. 2 the combination of half logical nut 1, swollen silk 2, circular boop 3 is screwed on bolt 4, due to the half logical He of nut 1
It is left-hand thread between swollen silk 2, and is right-hand thread between swollen silk 2 and bolt 4, so when rotating clockwise half logical nut 1, three's
Combination can inwards be moved together with integrality.When the front end of half logical nut 1 is come on object 5, continue firmly clockwise
Half logical nut 1 is turned, swollen silk 2 will be driven and rotated clockwise with the velocity of rotation less than half logical nut 1, and moved inwards,
And now half logical nut 1 increases the pressure of object 5 as swollen silk 2 is moved inwards, until the front end of swollen silk 2 top is to half logical spiral shell
On the baffle plate of female 1 inner chamber, its conical pipe is entirely insertable in circular boop 3.
In above process, the extruding due to circular boop 3 to the conical pipe of swollen silk 2, destroy swollen silk 2 spiral shell on bolt 4
Line, the self-destruction route of retreat, and one section of taper reduced inwards as shown in Figure 2 is defined on bolt 4, and the taper of swollen silk 2
Tube cavity also form the taper outwards reduced as shown in Figure 2, and this just more hinders swollen silk 2 and is displaced outwardly.As can be seen here,
The nut being made up of half logical nut 1, swollen silk 2, circular boop 3 will not move back button, therefore with auto-lock function.
After the above, if will half logical nut 1 unscrewed counterclockwise, circular boop 3 will not produce axially-movable and still tightly
Hoop makes swollen silk 2 be difficult to be displaced outwardly on the conical pipe of swollen silk 2, only with half logical frictional force between nut 1 and swollen silk 2,
It is not enough to drive swollen silk 2 synchronous therewith or to invert counterclockwise less than its rotating speed.So, in the state of swollen silk 2 is static,
It can only be half logical nut 1 oneself reversion counterclockwise.Because half it is logical be left-hand thread between nut 1 and swollen silk 2, so half logical nut 1 to
In move, press to object 5.As can be seen here, even unscrewed half leads to nut 1, is also the fastening again to object 5, it is difficult to will
The nut that half logical nut 1, swollen silk 2, circular boop 3 are constituted is unloaded from bolt 4, therefore with certain anti-theft feature.
Claims (2)
1. a kind of self-locking nut is formed by half logical nut, swollen silk and circular boop with left-hand thread threaded connection, be it is characterized in that：Swollen silk by pipe and
Conical pipe two parts are constituted, and cylindrical parts internal thread is right-hand thread, and external screw thread is left-hand thread, and capillary portion non-threaded, its outside is opened
There is shrinkage joint.
2. self-locking nut according to claim 1, is characterized in that：Half logical nut sets up 1 equivalent in plain nut side
Ring baffle, its internal thread is left-hand thread.
