Abstract
The utility model provides a locking force adjustable locknut, including the nut body, nut body center is the screw hole, nut body appearance is at the hexagonal structure, be provided with the steel ball groove in nut body every hexagonal inboard, steel ball groove one side leads to for complete, the opposite side leads to and only allows 13 steel ball to expose nut body upper surface for half, thus, the steel ball is located steel ball tank bottom portion, be provided with compression spring above the steel ball groove, compression spring upper portion is gland nut, gland nut matches with the screw thread of steel ball inslot side, thus, alright in the past steel ball tank bottom portion gland nut twists, thereby adjust the pretightning force of steel ball, the utility model discloses simple structure, some big nuts that need often to dismantle of specially adapted are locked, the utility model discloses the long -time use can not become invalid yet.
Description
Technical field
This utility model relates to technical field of fastening, is specifically related to a kind of coupling mechanism force adjustable
Stop nut.
Background technology
Bolt and nut, as usual removable fastening parts, extensively applies each field
On plant equipment, power, mechanical component, and at sharp pounding or irregular strength fluctuation environment
In, it may occur that nut loosening, obscission, therefore cause mechanical accident, the most serious
Security incident, and general stop nut often loses locking functions the most afterwards in use,
Nut how is made to keep self-lock ability for a long time, in particular, in that some uses that it is frequently necessary to dismounting are big
The use occasion of nut, still has certainly in the urgent need to one nut in the case of often dismounting
The nut of lock ability.
Utility model content
For problem present in background technology, the utility model proposes a kind of coupling mechanism force
Adjustable stop nut.
This utility model is addressed by following technical proposals: a kind of coupling mechanism force is adjustable
Stop nut, including nut body, nut body center is screwed hole, nut body profile
At hexagonal structure, being provided with steel bead groove inside each hexagonal of nut body, steel bead groove side is
All-pass, opposite side is half logical only to allow the steel ball of 1/3 to be exposed to nut body upper surface, so,
Steel ball is positioned at bottom steel bead groove, and steel bead groove is provided above with compression spring, and compression spring top is
Clamp nut, clamp nut mates with the screw thread inside steel bead groove, so, just can steel ball in the past
Trench bottom twists clamp nut, thus regulates the pretightning force of steel ball.
Further, described clamp nut back is hex slot, and hex slot is interior with common
Die nut mates.
This utility model the most if desired has self-lock ability, it may be that expose steel ball
The side be towards seal face, after fitting with seal face in steel ball exposed portion, along with this reality
Twisting further downward with novel, steel ball is pulled in nut body, and compression spring is had by steel ball
One thrust, in this thrust to nut body, is finally applied to nut body and bolt
Engaged thread on so that occlusion more step up, effectively placed nut body pine
Fall, and this utility model can also regulate the elastic force of compression spring by clamp nut, come
Increase or reduce the coupling mechanism force of nut body.
This utility model simple in construction, being particularly well-suited to some needs the big of often dismounting
Nut is locked, and this utility model uses for a long time and also will not lose efficacy.
Accompanying drawing explanation
Fig. 1 is of the present utility model with broken section overall structure schematic diagram one.
Fig. 2 is of the present utility model with broken section overall structure schematic diagram two.
Detailed description of the invention
With detailed description of the invention, this utility model is made the most below in conjunction with the accompanying drawings
Describe: as depicted in figs. 1 and 2, a kind of adjustable stop nut of coupling mechanism force, including nut originally
Body 1, nut body 1 center is screwed hole 1.1, nut body 1 profile at hexagonal structure,
Being provided with steel bead groove 1.2 inside each hexagonal of nut body 1, steel bead groove 1.2 side is complete
Logical, opposite side is that the steel ball 2 of half logical only permission 1/3 is exposed to nut body 1 upper surface, this
Sample, steel ball 2 is positioned at bottom steel bead groove 1.2, and steel bead groove 1.2 is provided above with compression spring 3,
Compression spring 3 top is clamp nut 4, the screw thread inside clamp nut 4 and steel bead groove 1.2
Coupling, so, just can stubborn clamp nut 4 bottom steel bead groove 1.2 in the past, thus regulate steel ball
The pretightning force of 2.
Described clamp nut 4 back is hex slot 4.1, and hex slot 4.1 is interior with common
Die nut mates.
This utility model the most if desired has self-lock ability, it may be that expose steel ball 2
The side be towards seal face, after fitting with seal face in steel ball 2 exposed portion, along with this
Twisting further downward of utility model, steel ball 2 is pulled in nut body 1, and steel ball 2 is to pressure
Contracting spring 3 has a thrust, in this thrust to nut body 1, is finally applied to spiral shell
On the engaged thread of maternal body 1 and bolt, so that occlusion more steps up, effectively put
Put nut body 1 to come loose, and this utility model can also have been regulated by clamp nut 4
The elastic force of compression spring 3, increases or reduces nut body 1 coupling mechanism force.
Protection domain of the present utility model includes but not limited to embodiment of above, this reality
It is as the criterion with claims with novel protection domain, any this area that this technology is made
The replacement that will readily suggest themselves to such skilled persons that, deform, improve and each fall within protection domain of the present utility model.
Claims (1)
1. the adjustable stop nut of coupling mechanism force, including nut body (1), nut body
(1) center is screwed hole (1.1), and nut body (1) profile is at hexagonal structure, at nut
Being provided with steel bead groove (1.2) inside body (1) each hexagonal, steel bead groove (1.2) side is
All-pass, opposite side is that the steel ball (2) of half logical only permission 1/3 is exposed on nut body (1)
Surface, so, steel ball (2) is positioned at steel bead groove (1.2) bottom, and steel bead groove (1.2) is above
Being provided with compression spring (3), compression spring (3) top is clamp nut (4), compresses spiral shell
