Abstract
The utility model discloses a locking hexagon nut and a locking device thereof. A hollow cylinder with an external thread and a cylindrical hole groove with an external thread are arranged on the corresponding end faces of a nut body and a thickened gasket respectively, and a spring washer is annularly arranged on the hollow cylinder, so that the nut body, the gasket and the spring washer are organically combined into an integral structure. The locking hexagon nut and the locking device thereof are convenient to use, and have a good locking effect.
Description
Technical field
The utility model relates to a kind of fastening piece, especially a kind of hexagonal locknut and locking device thereof.
Background technique
Pad and spring washer have certain effect to reducing nut loosening.But exist two big not enough: the one, before screwing on nut, to use trouble at bolt cover Upper gasket and spring washer earlier, when maintenance, also usually lose; The 2nd, only rely on the elastic force of spring washer, when the long-time strenuous vibration of machinery, prevent that the effect of becoming flexible is not ideal enough, owing to nut loosening, coming off influences the situation that machinery runs well and happen occasionally.
The model utility content
The technical problems to be solved in the utility model is: provide a kind of nut body, pad and spring washer to be combined into an integral body, easy to use, the good hexagonal locknut of anti-loosing effect and locking device thereof.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: comprise nut body, pad and spring washer, nut body is provided with hexagonal locknut and the locking device thereof of tapped through hole, an end face upper edge tapped through hole of nut body radially is set to be with externally threaded hollow cylinder, pad thickening also is provided with the tapped through hole a identical with tapped through hole, on the end face of pad for be provided with internal thread and with the cylindrical hole slot of the outside thread interlock of hollow cylinder periphery.
Described hollow cylinder and cylindrical hole slot can be separately positioned on pad and the mutual corresponding end face of nut body.
The outer periphery portion of described pad is six corner angle consistent with nut body.
Described spring washer is arranged on the hollow cylinder in the form of a ring.
The utility model has the advantages that: an end face upper edge tapped through hole by nut body radially is set to be with externally threaded hollow cylinder, the pad thickening also is provided with the tapped through hole a identical with tapped through hole, on the end face of pad for be provided with internal thread and with the cylindrical hole slot of the outside thread interlock of hollow cylinder periphery, and be arranged on spring washer on the hollow cylinder in the form of a ring, like this, the nut body after the improvement, pad and spring washer organically are combined into a whole mechanism.During use, as long as this whole mechanism is put bolt, after screwing, pad is screwed with nut body mutually with opposite direction, the screw thread on nut body and the pad is interlock inflexibly just, even the long-time strenuous vibration of machinery can not become flexible yet again.
Hollow cylinder and cylindrical hole slot are separately positioned on pad and the mutual corresponding end face of nut body, and effect and effect on the end face mutual corresponding with being separately positioned on nut body and pad are identical.The spinning in and out of pad are convenient in the outer periphery portion of pad for six corner angle consistent with nut body.
Description of drawings
The concrete structure of model utility is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is according to the nut body of model utility proposition and the structural representation of spring washer concrete structure.
Fig. 2 is the structural representation according to the pad concrete structure of model utility proposition.
(1) is nut body among the figure, and (2) are pad, and (3) are spring washer, and (4) are tapped through hole, (4-1) be tapped through hole a, (5) are the hollow cylinder outside thread, and (6) are hollow cylinder, (7) be cylindrical hole slot internal thread, (8) are cylindrical hole slot, and (9) are the pad corner angle.
Embodiment
Below in conjunction with details and the working condition of accompanying drawing detailed description according to the concrete device that the utility model proposes.
As shown in drawings, comprise nut body (1), pad (2) and spring washer (3), nut body (1) is provided with hexagonal locknut and the locking device thereof of tapped through hole (4), an end face upper edge tapped through hole (4) of nut body (1) radially is set to the hollow cylinder (6) with outside thread (5), pad (2) is thickeied and is provided with the tapped through hole a (4-1) identical with tapped through hole (4), on the end face of pad (2) for be provided with internal thread (7) and with the cylindrical hole slot (8) of outside thread (5) interlock of hollow cylinder (6) periphery; The outer periphery portion of pad (2) is six corner angle (9) consistent with nut body (1); Spring washer (3) is arranged on the hollow cylinder (6) in the form of a ring.
Above-described embodiment just is described a kind of mode of execution of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
