The utility model content

The purpose of this utility model provides a kind of buckle jockey convenient, that be connected firmly that assembles.

For this reason, the technical scheme that the utility model adopted is: the buckle jockey, comprise a shackle member and a nut, shackle member has external screw thread in its axial rear end, nut has internal thread, and internal and external screw thread intermeshes, and it is characterized in that: the externally threaded front end of shackle member has at least two arc shaped hooks in a circumferential direction, arc shaped hook one end links to each other with the shackle member body, and the other end has outwards outstanding briar tooth; The front end of nut has Non-return ring, and Non-return ring is made up of the wavy locking tooth of repeated arrangement on the inner periphery.

Described each wavy locking tooth is made of a long limit and a minor face, has two end points and a summit; Two end points are identical apart from the distance in the center of circle, greater than the distance of summit far from the center of circle, thereby make two end points and summit constitute triangle, and bigger base angle is 80～90 degree in the triangle.

Described nut front end also has the chamfering of inside indentation on the circumferencial direction.

The utility model rotates in the direction of the clock at nut, in the process that meshes with connector, when the Non-return ring of nut front end when arc shaped hook on the connector contacts, because the nut front end has on the circumferencial direction the inwardly chamfering of indentation, thereby arc shaped hook on the shackle member can be slipped in the Non-return ring 5 that the nut front end has smoothly.

The utility model has wavy locking tooth because of repeated arrangement on the inner periphery of Non-return ring, each locking tooth is made of a long limit and a minor face, have two end points and a summit, two end points are identical apart from the distance in the Non-return ring center of circle, greater than the distance of summit apart from the Non-return ring center of circle, thereby make two end points and summit constitute triangle, and then the long limit and the minor face of locking tooth all have constant slope as can be known; So after arc shaped hook enters Non-return ring, arc shaped hook at first contacts with the end points that is positioned at long side, along with nut rotates in the direction of the clock, the long limit of locking tooth can produce pressure to arc shaped hook, make arc shaped hook inwardly indentation gradually of the gradient along long limit from the end points of long side, after crossing the summit, outwards slide to the end points of short brink gradually along the gradient of minor face.After nut was rotated in place, the briar tooth of arc shaped hook just in time was in a locking tooth and is positioned on the end points of short brink, and the increment and the minor face of briar tooth are inconsistent.At this moment, because of the base angle that is positioned at short brink in the triangle bigger, so minor face has bigger gradient as can be known; Because the big more resistance that produces of gradient on limit is also just big more, so minor face produces bigger resistance, acts on the increment of briar tooth; Simultaneously, arc shaped hook itself also has elasticity preferably, is subjected to flexible effect to be difficult for stressed being compressed, and therefore by the resistance of minor face and the elastic interaction of arc shaped hook, makes shackle member more firm with being connected of nut.

The utility model when the base angle that is positioned at short brink in the triangle be 90 when spending, shackle member is connected non-dismountable with nut.

For the ease of in actual use, the workman overhauls equipment, the base angle that is positioned at short brink in the preferred triangle of the utility model is 80～85 degree, so minor face has gradient as can be known, so nut still can be in the effect of big external force, by rotation counterclockwise, the pressure that utilizes minor face that arc shaped hook is produced, the end points of short brink is inwardly compressed gradually along the gradient of minor face, cross the summit after, outwards slide to the end points of long side along the gradient on long limit.

In addition, the nut front end has the chamfering of inside indentation on the circumferencial direction, and is when nut is rotated counterclockwise, more smooth.

Compared with prior art, structure of the present utility model is more reasonable, especially matches with briar tooth on the arc shaped hook by the locking tooth on the Non-return ring, has both further strengthened the steadiness that shackle member is connected with nut, and it is safer, reliable to make product use; Simultaneously, also greatly facilitate assembling or dismounting between shackle member and the nut, improved the operating efficiency of assembling, inspection and maintenance.

Embodiment

Referring to accompanying drawing.Present embodiment comprises a shackle member 1 and a nut 2, described shackle member 1 has external screw thread in its axial rear end, externally threaded front end has two arc shaped hooks 3 in a circumferential direction, and arc shaped hook 3 one ends link to each other with shackle member 1 body, and the other end has outwards outstanding briar tooth 4; Described nut 2 has internal thread, and its front end has Non-return ring 5, and Non-return ring 5 is made up of the wavy locking tooth 6 of repeated arrangement on the inner periphery; Each wavy locking tooth 6 is made of a long limit AC and a minor face BC, has one first terminal A, one second terminal B and a summit C; Wherein, first terminal A is identical apart from the distance of Non-return ring 5 center of circle O with second terminal B, greater than the distance of summit C apart from Non-return ring 5 center of circle O, thereby makes first terminal A, second terminal B and summit C constitute △ ABC, and ∠ CAB is that 10 degree, ∠ ABC are 85 degree among this △ ABC.

Described nut 2 front ends also have on the circumferencial direction the inwardly chamfering of indentation, and the outside that this chamfering is positioned at nut 2 front ends because of Non-return ring 5 is higher than inner edge and forms.

Present embodiment rotates in the direction of the clock at nut 2, in the process that meshes with connector 1, when the Non-return ring 5 of nut 2 front ends when arc shaped hook 3 on the connector 1 contacts, because nut 2 front ends have on the circumferencial direction the inwardly chamfering of indentation, thereby arc shaped hook 3 on the shackle member 1 can be slipped in the Non-return ring 5 that nut 2 front ends have smoothly.Afterwards, because of ∠ CAB among the △ ABC is 10 degree, long as can be known limit AC has less gradient, so arc shaped hook 3 is after slipping into Non-return ring 5, long limit AC can produce pressure to arc shaped hook 3, arc shaped hook 3 is inwardly compressed along the gradient of long limit AC gradually from first terminal A, cross summit C, outwards slide to second terminal B along the gradient of minor face BC.After nut 2 was rotated in place, the briar tooth 4 of arc shaped hook 3 just in time was on second terminal B of a locking tooth 6, and the increment of briar tooth 4 and minor face BC are inconsistent.At this moment, because of ∠ ABC among the △ ABC is 85 degree, minor face BC has bigger gradient as can be known; Because the big more resistance that produces of gradient on limit is also just big more, so minor face BC produces bigger resistance, acts on the increment of briar tooth 4; Arc shaped hook 3 itself also has good elasticity simultaneously, under flexible effect, be not subject to pressure that minor face BC produces and inwardly indentation, therefore by the resistance of minor face BC and the elastic interaction of arc shaped hook 3, can make shackle member 1 and being connected of nut 2 not be subject to external force and become flexible.

Present embodiment is because of checking or maintenance, in the time of need dismantling shackle member 1 and nut 2, because minor face BC has gradient, nut 2 front ends have the chamfering of inside indentation on the circumferencial direction, so nut 2 still can rotate by counter clockwise direction smoothly being subjected to big external force effect, utilize minor face BC that arc shaped hook 3 is produced pressure, make arc shaped hook 3 from second terminal B gradient along minor face BC inwardly compressed gradually, cross summit C, outwards slide to first terminal A along the gradient of long limit AC.
