Abstract
The utility model discloses an anti-loosing screw nut, being composed of a screw nut body part and a plastic washer part, wherein, one side end of the screw nut body is a circular ring-shaped thin case body, the plastic washer is embedded in the case body and is appressed with the end surface of the screw nut, forming a whole. An internal diameter of the washer is consistent with an internal diameter of a screw thread of the screw nut, the thickness is equivalent to one to three screw thread spaces and the operation is the same as a common screw nut. The utility model which has the advantages of simple structure and convenient and quick use can not damage the screw thread of the screw bolt and can be widely used for the occasions needing fastening by the screw bolt and the screw nut, such as various mechanical parts, articles, etc.
Description
The utility model belongs to the mechanical fastening system technical field, is a kind of lock nut that is used for fixing mechanical part or object.
Nut and bolt are a kind of application mechanical fixed parts very widely.When common nut cooperated stationary mechanism part with bolt, because the motion or the vibrations of machinery, the time was long slightly, and nut becomes flexible easily, comes off, and made fixture produce displacement or loosening.Gently then, mechanical part is caused damage, heavy then may cause fault or accident.In order to solve the loosening problem of nut, people have designed many anti-loosening nuts or device at different application conditions and environment.Wherein, have at metal spring sheet of nut body top increase, screw thread by the spring sheet stud bolt reaches locking purpose, as Chinese patent " metal insert hexagonal locking nut " (CN88217962.4) and " resilient insert lock nut " (CN8821249.X).The handlebar nuts and washers is designed to eccentric, as " loose-proof self-lock nut " (CN91201176.9).The composite structure of employing form is also arranged, and as " combined type lock nut " (CN87202882), all these lock nuts or device have played some anti-loosening effect to a certain extent.But the general more complicated of their structure, and the use operation that has is convenient inadequately, and screw thread on the easy damage bolt that has declines nut and causes difficulty.
The purpose of this utility model is to provide a kind of simple in structure, easy to use, anti-loosening nut that can not cause damage to screw thread on the bolt.
The lock nut of the utility model design comprises nut body and two parts of plastic washer, wherein a side of nut body is a garden annular thin walled shell, plastic washer is embedded in this shell ring and is close to the end side surface of nut body and constitutes an integral body, and the plastic washer internal diameter is consistent with the internal diameter of nut.
The lock nut of the utility model design, the thickness of plastic washer wherein is not less than a flight pitch of nut, generally when 1～3 times during to the pitch of thread, can avoid becoming flexible of nut well.Thickness be 1.3～2.5 times when the pitch of thread, effect is ideal.
The profile of this lock nut can be common nut shape, as six-sided nut.And applicable to the nut of various standard models.During use, this lock nut equally is screwed on the corresponding bolts by common nut.After nut was fixedly tightened parts, the screw thread on the bolt was shot the internal surface of plastic washer automatically, thereby had avoided fixed component loosening and displacement in motion or vibrations process.Because plastic washer has certain elasticity, when the tap of bolt is fashionable can damaged screw.And, the same with common nut convenient when nut is resigned from office, do not increase any operational trouble.
This lock nut is simple in structure, and is easy to use, and can save compression spring or other locking devices that people adopt usually.Be applicable to the occasion of various use nuts such as mechanical part, rolling stock, bolt, the wide application amount is big.
Below in conjunction with embodiment, further describe structure of the present utility model.
Fig. 1 is the cut-away view of this nut along the middle section.
Fig. 2 is this nut plan view.
Wherein 1 is nut body, and 2 is the garden annular book housing of nut body one side, and 3 is plastic washer.
Embodiment: corresponding to standard M10 hexagon nut, opposite diameter 16mm, to angular diameter 19.85mm, height 8mm, the book girdle height 4.5mm of nut body one side, internal diameter 14mm, the plastic washer external diameter is identical with book girdle internal diameter, is 14mm, internal diameter is consistent with the nut nominal diameter, be 10mm, the height of thickness and book girdle adapts, and is 3.5mm.During manufacturing, make nut body (the book girdle part that comprises a side) by machining, the plastic washer of making is in advance placed in the book girdle, with seaming machine the book shell is flattened, the packing ring envelope is pressed in the ring, make nut body and packing ring constitute an integral body, re-plating promptly gets the lock nut corresponding to standard M10 hexagon nut.
Claims (3)
1, a kind of lock nut is combined by nut body and plastic washer, it is characterized in that nut body one side is a garden annular book housing, in plastic washer is embedded in, and is close to the nut side end face and constitutes an integral body, and the packing ring internal diameter is consistent with the nut internal diameter.
2, lock nut according to claim 1, the thickness that it is characterized in that described plastic washer be 1～3 times to flight pitch.
