Abstract
The utility model relates to a fastener, that is to say, an improved screw bolt and a screw nut. The fastener comprises the screw bolt. A groove is arranged on the contact end surface of the screw bolt and the screw nut. A rolling bead is arranged inside the groove. The groove is a wedge-shaped groove. The fastener comprises the screw nut which is used with the screw bolt together. The groove is arranged on the contact end surface of the screw bolt and the screw nut. The rolling bead is arranged inside the groove. The groove is the wedge-shaped groove. The fastener comprises a gasket which is used with the screw bolt and the screw nut together. A groove is arranged on the end surface of the gasket. A rolling bead is arranged inside the groove. The fastener has the advantage that the fastener is not loosened after fastened, and has the advantage of permanent fastening. The anti-theft purpose can be achieved by using in different fields. Because the fastener can replace welding, the fastener has the advantages of convenient use and operation and low cost at the same time.
Description
The utility model relates to firmware, is a kind of improved bolt and nut.
Existing bolt, nut all are traditional normal structures, though it has many advantages, but find that in use it still has deficiency:, after use a period of time, easily produce loosening when fastening a certain parts, particularly when fastening transmission part, this automatically loosening phenomenon very easily causes danger.Simultaneously, it does not have theftproof performance.In addition, after some parts need connect, do not need demolition, then must adopt welding manner, this gives in the operation and results in hand cramps, and makes cost up.Therefore, how to make fastening piece can secure component after, be difficult for looseningly, do not need demolition, can reach permanent fastening, be one of problem that the technician need solve in the present fastener areas.
The purpose of this utility model is, provide a kind of bolt, nut and with bolt, the common packing ring that uses of nut, make them have fastening loosening, use, easy to operate and have an advantage of theftproof performance.
The utility model is for finishing the foregoing invention purpose, and the technological scheme that provides is: a kind of bolt, on the contact end face of bolts and nuts, offer groove, and ball is set in the groove.Groove is a wedge slot.A kind of nut that uses jointly with bolt, nut is offered groove with contacting of bolt on the end face, ball is set in the groove.Described groove is a wedge slot.A kind of packing ring that uses jointly with bolt and nut is offered groove on the end face of packing ring, ball is set in the groove.Offer groove respectively on two end faces of packing ring, ball is set in the groove.Described groove is a wedge slot.
Bolt and nut described in the utility model and packing ring owing to slotting on its end face and ball being set, so in use, have the tight advantage in fastening back, and permanent fastening advantage are arranged, and are used in different field and can reach antitheft purpose.Because its alternative welding has easy to operate, the lower-cost advantage of use simultaneously.
Description of drawings: accompanying drawing 1 is bolt, nut, packing ring, the phase diagram that is used in combination, and 1 is bolt, the 2nd among the figure, packing ring, the 3rd, nut.Accompanying drawing 2 is end-face structure schematic representation of bolts and nuts contact, and 4 is grooves among the figure, the 5th, and ball.Accompanying drawing 3 is washer face structural representations, and 6 is grooves among the figure, the 7th, and ball.Accompanying drawing 4 are nuts with bolt contact the end face structural representation.8 is grooves among the figure, the 9th, and ball.Accompanying drawing 5 is A-A cross-sectional view in the accompanying drawing 2, and accompanying drawing 6 is B-B cross-sectional view in the accompanying drawing 3, and accompanying drawing 7 is C-C cross-sectional view in the accompanying drawing 4, and sectional drawing is mainly illustrated the structure of groove and ball.
The contrast accompanying drawing, embodiment is described further to the utility model: when bolt 1 nut 3 uses jointly among the figure, offer wedge slot 4 on the contact end face of two parts, ball 5 is set in the groove 4, this ball 5 can be spheroid or cylinder.Present embodiment adopts spheroid.Nut 3 is offered groove 6 with contacting of bolt 1 on the end face, groove 6 is wedge slots, and ball 7 is set in the groove 6, and this ball 7 is spheroids.With the bolt 1 nut 3 common packing rings 2 that use, on the end face of packing ring 2, offer groove 8, also can on two end faces of packing ring 2, offer groove 8 respectively, this groove 8 is a wedge slot, and ball 9 is set in the groove 8, ball 9 is cylinders.When the utility model uses, work as bolt, when nut or packing ring and fastener were fastening, ball closely contacted with fastened body end face in the wedge slot, formed the friction basis.When reverse turn, when unclamping because during in the identical angle of rotation, the ball in the wedge slot makes axial distance that ball body produces greater than pitch under the effect of friction, so, in case after adopting the utility model fastening, be impossible loosening, reach permanent fixing.
