Description
Technical field
The utility model is related to a kind of structure of securing member, belongs to field of mechanical technique, more particularly to
A kind of locking device.
Background technology
Since being born nut, the accreditation of consumers in general is just obtained and the substantial amounts of manufacturing machine that is applied to manufactures row
Industry, such as electromechanical installation, building machinery, farm machinery every field, are a kind of essential basic mechanical organs, each
Engineering product, no matter its composition has more complicated, is actually required for using threaded fastener.With other most of bind mode phases
Than the considerable advantage of threaded fastener is that it can dismantle and reuse.However, this is also the root place of problem, because
Threaded fastener easily occurs from loosening phenomenon.Since the industrial revolution, screw thread is not solved very well from loosening always one
Certainly the problem of.Existing technology is that, using methods such as locking plate, pin, nylon insertion, deformation screw thread, chemical gluings, what is existed asks
Topic is the time for having delayed fastener voluntarily to release to a certain extent, but releases problem and do not solve at all.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of locking device.
The utility model is achieved through the following technical solutions：A kind of locking device, including mother nut and stop nut,
It is provided with one end face of the mother nut in the frustum of protrusion, frustum and is provided with what is communicated with the screw thread on mother nut body
Be provided with screwed hole, the frustum in the vertical slot with screwed hole diameter parallel, the screwed hole of the stop nut be provided with
The taper hole that the frustum matches.
In such scheme, the column of protrusion, post are provided with the stop nut on one end end face relative with taper hole
It is provided with shape body on the screwed hole communicated with the screw thread on nut body, the cylinder of column and is provided perpendicular to column axle
The translot of line, the depth of the translot is more than the semicircle of column.
In such scheme, vertical slot is set to four vertical slots being distributed in " cross " on the frustum.
In such scheme, the outside diameter of the taper hole is less than the outside diameter of the frustum, and the depth of the taper hole is big
In the height of the frustum.
Compared with prior art, its advantage is the locking device：
1st, the utility model locking device integrates a variety of anti-loose structures, and anti-loosing effect is multiplied, and substantially avoids
Nut after fastening is produced from the phenomenon of loosening.
2nd, the utility model locking device installs simple, and dismounting is also simple, reusable.
3rd, two nuts in the locking device can be used cooperatively, and can be also used separately, the scope of application is big.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model locking device；
Fig. 2 is the structure chart of part 1 in Fig. 1；
Fig. 3 is the structure chart of part 2 in Fig. 1；
Fig. 4 is Fig. 3 top view.
In figure：1. stop nut, 2. mother nuts, 3. taper holes, 4. translots, 5. frustums, 6. vertical slots, 7. columns.
Embodiment
The utility model locking device is further described with specific embodiment below in conjunction with the accompanying drawings：
Fig. 1 is the structural representation of the utility model locking device, and Fig. 2 is the structure chart of part 1 in Fig. 1, during Fig. 3 is Fig. 1
The structure chart of part 2, Fig. 4 is Fig. 3 top view.In figure, the locking device includes mother nut 2 and stop nut 1, the main spiral shell
It is provided with the upper surface of mother 2 in the frustum 5 of protrusion, frustum 5 and is provided with the screwed hole communicated with the screw thread on mother nut body,
The vertical slot 6 being provided with frustum 5 on the vertical slot 6 with screwed hole diameter parallel, frustum 5 is set to erect in four of " cross " distribution
Groove.Be provided with the screwed hole of stop nut 1 on the taper hole 3 matched with frustum 5, the upper surface of stop nut 1 be provided with it is convex
It is provided with the column 7 gone out, column 7 on the screwed hole communicated with the screw thread on stop nut body, the cylinder of column 7
The translot 4 of column body axis is provided perpendicular to, the depth of the translot is more than the semicircle of column, and translot 4 is set to two
And it is symmetrical on column 7, two translots 4 stagger above and below the axis along column 7, and the notch of translot 4 is along column 7
Axis crimp.The outside diameter of taper hole 3 is less than the outside diameter of the frustum 5, and the depth of taper hole 3 is more than the height of frustum 5
Degree, certain gap is left to two nut pretensions.
During fastening, mother nut 2 is first screwed on, then screws on stop nut 1, can also be screwed on simultaneously, when mother nut 2 is tightened, after
Continuous to tighten stop nut 1, taper hole 3 is pressed close to coordinate with frustum 5, and stop nut 1 first is to 2 one downward power of mother nut, first
The gap between the external screw thread on the screw and bolt in nut is eliminated, first of locking power is produced.Secondly, taper hole 3 is to frustum 5
There is the enclasping force of a radial direction so that the frustum 5 of vertical slot 6 produces elastic deformation, hold tightly on the external screw thread of bolt, produce second
The locking power in road.3rd, two translots 4 staggeredly deformed produce very big frictional force to bolt external screw thread, produce the 3rd road locking
Power.These three anti-loose structures work simultaneously, and anti-loosing effect is multiplied, and substantially avoid the nut after fastening and are produced from pine
Dynamic phenomenon.
It is described above, only it is preferred embodiment of the present utility model, not makees any formal to the utility model
Limitation, although the utility model is disclosed above with preferred embodiment, but is not limited to the utility model, any ripe
Know professional and technical personnel, do not departing from the range of technical solutions of the utility model, when the method using the disclosure above and
Technology contents make a little change or are modified to the equivalent embodiment of equivalent variations, as long as being without departing from the utility model technology
The content of scheme, according to technical spirit of the present utility model above example is made it is any it is simple modification, equivalent variations with
Modification, in the range of still falling within technical solutions of the utility model.
