Description
Technical field
The utility model is related to device assembly assembling loosing Prevention Technology field, specially a kind of jam nut.
Background technology
In current mechanical industry and some home electronics, screw is the work of main fastening apparatus assembly
Have, also someone makes screw be screw or screw, screw rod or lead screw, and screw is common name in fact, and screw, lead screw are all
Mutually distinguishing, screw is typically named wood snail in fastening wooden part, working of plastics, and lead screw is machine screws, is front end tack
That, pitch is smaller, uniformly, is generally used for fastening metal, machine part, and this outside nut also has many types in design.
But in current screw in use, the problem of some are obvious occurs, such as the long screw meeting of use time
Loosen, and regardless of how fasten and all again can not normally use it, the life-span of so this screw just reaches, undoubtedly
This occupation mode causes the waste of material and the raising of cost.
Utility model content
To achieve the above object, the utility model provides following technical scheme：A kind of jam nut, including nut, it is described
Pane, which is connected with the outside of bolt, the bolt, is provided with plain cushion, and the plain cushion side is provided with preceding backing plate, the preceding backing plate side
Provided with frid, the frid side is provided with mounting groove, is joined directly together between the frid and mounting groove by relief spring, described
Relief spring has 4, respectively the uniform surrounding for being arranged on mounting groove, and the preceding backing plate, frid and mounting groove are each provided at spiral shell
The outside of bolt, the side of the mounting groove is provided with spring washer, and the side of the spring washer is provided with fastening nut, the side of the fastening nut
Face is provided with locking nut, and the locking nut side is provided with anti-decylization.
As a kind of preferred technical scheme of the utility model, frid and the mounting groove outward appearance is circular design, institute
State frid diameter and mounting groove internal diameter it is equal, be all 4 centimetres.
As a kind of preferred technical scheme of the utility model, the fastening nut fastens for right-spiral, the locking screw
Mother is levoform locking.
It is inverted trapezoidal structure, the anticreep on the outside of the preceding backing plate as a kind of preferred technical scheme of the utility model
Trapezium structure is designed as on the outside of ring, inner side is half engraved structure, side-closed.
Compared with prior art, the beneficial effects of the utility model are：The jam nut, passes through the combination of plain cushion and spring washer
Use, reduce the shearing force of spring plane shearing slip, the preceding backing plate of inverted trapezoidal structure becomes the shear pressure born of bolt
Be changed to vertical pressure, prevent bolt from centre position destroy, lay front of the slot relief spring use can effectively reduce it is vertical
To pressure, prevent from producing destruction to securing elements, mounting groove mainly shields to internal structure, in addition, fasten nut and
The left-handed right-hand design of locking nut can be such that fastening more consolidates, and the trapezium structure of anti-decylization designs the vertical pressure that will can be born
Power outwards discharges, and prevents screw from being slipped from nut position.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Embodiment：
Fig. 1 and Fig. 2 are referred to, the utility model provides a kind of technical scheme：A kind of jam nut, including nut 1, it is described
The side of nut 1 is connected with bolt 2, and the outside of bolt 2 is provided with plain cushion 3, and the side of plain cushion 3 is provided with preceding backing plate 4, the foremast
The side of plate 4 is provided with frid 5, and the side of frid 5 is provided with mounting groove 6, relief spring 7 is passed through between the frid 5 and mounting groove 6
It is joined directly together, the relief spring 7 has 4, respectively the uniform surrounding for being arranged on mounting groove 5, the preceding backing plate 4, frid 5
The outside of bolt 2 is each provided at mounting groove 6, the side of the mounting groove 6 is provided with spring washer 8, and the side of the spring washer 8 is provided with fastening
Nut 9, the side for fastening nut 9 is provided with locking nut 10, and the side of locking nut 10 is provided with anti-decylization 11.
Preferably, frid 5 and mounting groove 6 outward appearance is circular design, the diameter and mounting groove 6 of the frid 5
Internal diameter it is equal, be all 4 centimetres, mounting groove 6 mainly shields to frid 5 and relief spring 7；It is described fastening nut 9 be
Right-spiral is fastened, and the locking nut 10 is locked for levoform, and the design of two kinds of reverse geometries adds the stabilization of nut fastening
Property；The outside of preceding backing plate 4 is inverted trapezoidal structure, and the outside of the anti-decylization 11 is designed as trapezium structure, and inner side is half hollow out
The shear pressure that bolt 2 is born is transformed to vertical pressure by structure, side-closed, inverted trapezoidal structure, prevents bolt 2 from centre
Position is destroyed, and trapezium structure outwards discharges the lateral pressure born, prevents screw from being slipped from nut position.
Specifically used mode and advantage：By the combined use of plain cushion and spring washer, reduce cutting for spring plane shearing slip
The shear pressure that bolt is born is transformed to vertical pressure by shear force, the preceding backing plate of inverted trapezoidal structure, prevents bolt from interposition
Destruction is put, lateral pressure can be effectively reduced by laying the use of front of the slot relief spring, prevent from producing securing elements destruction, peace
Put groove mainly to shield to internal structure, in addition, fastening can be made by fastening the left-handed right-hand design of nut and locking nut
More consolidate, the trapezium structure design of anti-decylization can outwards discharge the lateral pressure born, prevent screw from going out from nut position
Now slip.
