Abstract

The purpose of the present invention is that open one kind can only single dextrorotary unidirectionally dextrorotation cap nut.Have cone, the curved surface skewed slot of dextrorotation internal thread including inner cylinder, meet during unidirectional dextrorotation cap nut bolt connection can only right rotation be unable to anticlockwise, realize the one direction rotation of unidirectional dextrorotation cap nut.

Description

A kind of cextrorotory cap nut of list
Technical field
The present invention relates to cap nut technical field, more particularly to a kind of list of bolt connection fastening Anti-dismantling are cextrorotory Cap nut.
Background technology
At present, existing cap nut profile is mostly polyhedron design, left-handed can also be dismantled simultaneously in dextrorotation tightening screw cap Cap nut.Some cap nuts have installed prevention device additional, but the bidirectional rotation of cap nut is designed without changing to prevent left-handed dismounting Become, it is necessary to which additional measure reaches left-handed dismounting cap nut with regard to that can destroy prevention device.In being connected with fastening work, often It is commonly encountered the non-dismountable problem of cap nut for requiring bolt connection fastening.
The content of the invention
It is an object of the invention to provide a kind of cextrorotory cap nut of list, and it can overcome of the prior art aftermentioned scarce Fall into.
The present invention technical solution be:
A kind of unidirectional dextrorotation cap nut(Fig. 1), it is characterised in that including cone(1), curved surface skewed slot(2), internal thread(3), institute The inner cylinder for stating cone (1) has dextrorotation internal thread(3), top is provided with two symmetroid skewed slots(2);The curved surface skewed slot (2)For the skewed slot of the curved surface of clockwise direction.
Advantage for present invention is with effect:
1st, the unidirectional dextrorotation cap nut of the present invention is designed using dextrorotation internal thread cone.
Simplify the contact surface that conventional polyhedron cap nut and spanner can clamp, reached using the skew surface of cone and spanner The contact surface that can not be clamped, realize that spanner can not rotate unidirectional dextrorotation cap nut.
2nd, the single cextrorotory cap nut of the present invention(Fig. 1)Utilize cone(1)It is clockwise direction that top connection, which is provided with inclined-plane, Two symmetroid skewed slots(2)Realize the unidirectional right rotation fastening bolt of unidirectional dextrorotation cap nut.
Brief description of the drawings
The pictorial diagram of accompanying drawing 1-present invention
1-cone, 2-curved surface skewed slot, 3-dextrorotation internal thread in figure.
Embodiment
With reference to embodiment and accompanying drawing(Fig. 1)Technical scheme is further elaborated.
Such as unidirectional dextrorotation cap nut(Fig. 1)Shown, the unidirectional dextrorotation cap nut of the present invention, it implements to be that bolt connection fastens When cap nut works, the cone of unidirectional dextrorotation cap nut(1)Inner cylinder has dextrorotation internal thread(3)The external screw thread of connecting screw, Then by unidirectional dextrorotation cap nut socket wrench specially adapted for it adapter sleeve in cone(1)On, make skew back in unidirectional dextrorotation cap nut cover special Face connects and is caught in unidirectional dextrorotation cap nut cone respectively for two symmetroid card wedges of left hand direction(1)Top connection is provided with Inclined-plane is two symmetroid skewed slots of clockwise direction(2)It is interior, clamp unidirectional dextrorotation cap nut socket wrench specially adapted for it with existing common spanner The polyhedron that top connects, the connection of right direction rotary spanner drive unidirectional dextrorotation cap nut socket wrench specially adapted for it and connect the unidirectional right side of drive The cone of rotary screw cap(1)Right direction rotates, and realizes the fastening of the unidirectional dextrorotation cap nut of bolt connection.Left direction rotation is pulled Hand so that the cylinder interior inclined-plane of unidirectional dextrorotation cap nut socket wrench specially adapted for it is two symmetroid card wedges of left hand direction along oblique Face opposite direction and unidirectional dextrorotation cap nut cone(1)The inclined-plane that top connection is provided with is two symmetroid skewed slots of clockwise direction (2)Automatically depart from respectively, reach the purpose of non-dismountable unidirectional dextrorotation cap nut.

Claims (1)

  1. A kind of 1. cextrorotory cap nut of list(Fig. 1), it is characterised in that including cone(1), curved surface skewed slot(2), internal thread (3), the inner cylinder of the cone (1) has dextrorotation internal thread(3), top is provided with two symmetroid skewed slots(2);The song Face skewed slot(2)For the skewed slot of the curved surface of clockwise direction.
