Abstract
The utility model relates to a from locking-type locknut. The device is including the nut body, set up vertical wedge groove on the nut body internal surface, the inclined plane slope in wedge groove upwards sets up, sets up threaded hole on the upper surface in wedge groove, the screw hole runs through in the setting of nut body up end, threaded hole internal rotation has the connecting rod, and the connecting rod end that is located the wedge inslot articulates there is the wedge, the inclined plane of wedge is contradicted on the inclined plane in wedge groove, because the cooperation setting of connecting rod and wedge, through the swivel joint pole, contradicts the elasticity conflict piece on the wedge on the peripheral hardware bolt, prevents the rotation of peripheral hardware bolt, through can adjusting locking elasticity degree, the device can apply to industrial production, has very strong practicality.
Description
Technical Field
The utility model belongs to the technical field of the nut, especially, relate to a from locking-type locknut.
Background
The patent with an anti-loosening and anti-theft nut with an extrusion block external member is disclosed in the existing Chinese patent database, the application number is CN201721037911.7, the application date is 20170818, the grant notice number is CN207246196U, the grant notice date is 20180417, the patent comprises a nut body, the extrusion block external member, a square groove is arranged on the inner ring of the nut body, the square groove is provided with the extrusion block external member, the bottom of a thread in the nut body is provided with a wedge-shaped inclined plane, the included angle between the wedge-shaped inclined plane and the reverse extension line of the lower plane of the inner thread is 30 degrees, when the bolt and the utility model are mutually screwed, the tooth tip of the bolt is propped against the 30 degrees wedge-shaped inclined plane of the utility model, the normal force generated by the contact applied between the threads forms an angle of 60 degrees with the axis of the bolt instead of 30 degrees of the common threads, the anti-loosening effect is achieved by increasing the friction force, when the nut is screwed, the extrusion block external member is knocke, play the locking effect of theftproof, its weak point lies in: the nut can not adjust the depth of the extrusion block in the nut body in a sleeved mode, so that the extrusion force can not be adjusted, the looseness-proof tightness degree is changed, and certain limitation is realized.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is that current nut can't adjust locking elasticity degree, in order to improve its weak point, the utility model provides a from locking-type locknut.
In order to achieve the purpose, the utility model is realized by the following technical proposal:
the utility model provides a from locking-type locknut, including the nut body, set up vertical wedge groove on the nut body internal surface, the inclined plane slope of wedge groove upwards sets up, sets up threaded hole on the upper surface of wedge groove, the screw hole runs through in the setting of nut body up end, threaded hole internal rotation has the connecting rod, and the connecting rod end that is located the wedge inslot articulates there is the wedge, the inclined plane of wedge is contradicted on the inclined plane of wedge groove.
The utility model discloses the during operation, under the initial condition, the elasticity conflict piece of wedge is located the wedge inslot, connect the peripheral hardware bolt soon to the screw female internal, connect the completion back soon, through the swivelling joint pole, make the connecting rod remove towards the wedge inslot, promote the wedge downwards, thereby contradict the elasticity conflict piece on the wedge on the peripheral hardware bolt, prevent the rotation of peripheral hardware bolt, form self-locking effect, connect the degree of depth through adjusting the connecting rod soon, change the degree of depth that the elasticity conflict piece protrudes the wedge groove on the wedge, thereby adjust elasticity and support the extrusion force size of touch multitouch to the peripheral hardware bolt, adjust locking elasticity degree.
Compared with the prior art, the beneficial effects of the utility model are that: because the cooperation setting of connecting rod and wedge through the rotation connecting rod, contradicts the elasticity conflict piece on the wedge on the peripheral hardware bolt, prevents the rotation of peripheral hardware bolt, through can adjusting locking elasticity degree, the device can apply to industrial production, has very strong practicality.
The axial direction of the threaded hole is consistent with the inclination direction of the inclined surface of the wedge-shaped groove.
And a rubber pad is arranged on the surface of the elastic contact block.
The end of the connecting rod positioned outside the screw body is provided with a hand screwing part.
The hand-rotating part is sleeved with an anti-slip sleeve.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1 nut body, 2 wedge grooves, 3 screw holes, 4 connecting rods, 5 wedge blocks, 6 elastic contact blocks and 7 hand-screwing parts.
Detailed Description
The technical solution of the present application will be further described and explained with reference to the accompanying drawings and embodiments.
As shown in fig. 1, for a from locking-type locknut, including nut body 1, seted up vertical wedge groove 2 on the nut body 1 internal surface, the inclined plane slope of wedge groove 2 upwards sets up, set up screw hole 3 on the upper surface of wedge groove 2, screw hole 3 runs through in the setting of nut body 1 up end, has connect connecting rod 4 in screw hole 3 soon, and connecting rod 4 end that is located wedge groove 2 articulates there is wedge 5, and the inclined plane of wedge 5 is contradicted on the inclined plane of wedge groove 2. The axial direction of the threaded hole 3 is consistent with the inclined direction of the inclined surface of the wedge-shaped groove 2. The surface of the elastic contact block 6 is provided with a rubber pad. The end of the connecting rod 4 positioned outside the nut body 1 is provided with a hand-screwing part 7. The hand-rotating part 7 is externally sleeved with an anti-slip sleeve.
During operation, under the initial condition, the elasticity of wedge 5 is to touch multitouch 6 and is located wedge 2, connect the peripheral hardware bolt soon to nut body 1 in, connect the completion back soon, through swivel connected coupler 4, make connecting rod 4 remove in the wedge 2, promote wedge 5 downwards, thereby touch multitouch 6 with the elasticity on the wedge 5 contradicts on the peripheral hardware bolt, prevent the rotation of peripheral hardware bolt, form the auto-lock effect, through the degree of depth of connecing soon of adjusting connecting rod 4, change the degree of depth that elasticity touched 6 protrusion wedge 2 on the wedge 5, thereby adjust elasticity and touch multitouch 6 to the extrusion force size of peripheral hardware bolt, adjust locking elasticity degree.
The present invention is not limited to the above embodiments, and based on the technical solutions disclosed in the present invention, those skilled in the art can make some replacements and transformations for some technical features without creative labor according to the disclosed technical contents, and these replacements and transformations are all within the protection scope of the present invention.
