Abstract
The invention discloses an automatic locking nut which comprises a nut body. The nut body is provided with a threaded hole, an annular boss which extends outwardly is arranged at an end of the nut body, a nylon washer is arranged in a boss hole of the annular boss, and at least three pits are arranged on an end surface of the annular boss. The pits are equidistantly arranged on the end surface of the annular boss. The aperture of the nylon washer is smaller than that of the threaded hole. The automatic locking nut has the advantages that the pits are arranged on the annular boss by means of pressing, so that the contact surface of the boss and the nylon washer can be enlarged; the boss and the nylon washer can be in close contact with each other under the downward pressing effect, friction force can be increased, accordingly possible slipping and jacking dropping of the nylon washer can be effectively prevented, connection loosening can be prevented, convenience in assembly can be guaranteed, and the optimal fastening effects can be kept.
Description
Technical field
The present invention relates to a kind of nut, particularly a kind of automatic locking nut.
Background technique
In the prior art, self-locking nut is widely used in fastener areas with being connected of bolt.Current self-locking nut is normally provided with the annular extension part of protrusion in one end of plain nut, mosaic groove has been dug in inside at extension part, nylon washer is fixed in mosaic groove, when assembling, because of bolt outside thread large diameter-ratio nylon aperture large, during by nylon washer hole, screw thread can apply radial deformation pressure to nylon washer, allows it produce radially micro-deformation, makes nylon washer produce deformation and reaches oneself's locking.
When reality is used this self-locking nut; because nylon washer smoother; frictional force is little; and often can cause each other not laminating completely because of the careless mistake of processing method with nut body or contacting of extension part around; there is gap; therefore often may there is nylon washer and spin, assemble difficult situation, more likely cause nylon washer to be ejected or come off, situation loosening and that lost efficacy occurs to connect.
Summary of the invention
In order to overcome above-mentioned defect, the invention discloses a kind of automatic locking nut, by suppress some recesses on the annular boss that is used for fixing nylon washer, be pressed on nylon washer by recess, realize and stop nylon washer to slide.
The present invention is achieved through the following technical solutions:
A kind of automatic locking nut, comprises the nut body that is provided with tapped hole, and described nut body one end is provided with outward extending annular boss, in the boss hole of described annular boss, is provided with nylon washer, and the end face of annular boss is provided with recess.
Described recess decile is arranged on the end face of annular boss.
Described recess is at least provided with three.
The aperture of nylon washer is less than the aperture of tapped hole.
Compared with prior art, tool has the following advantages in the present invention:
By suppress recess on annular boss, boss and nylon washer surface of contact are increased, press down simultaneously and make mutual contact also tighter, frictional force increases, therefore can effectively prevent the slip that nylon washer may occur and eject obscission, prevent from connecting and fluff, ensure easy to assemblyly, keep best fastening effect.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is A-A direction cross-sectional schematic in Fig. 1.
Embodiment
The present invention includes the nut body 1 that is provided with tapped hole 2, described nut body 1 one end is provided with outward extending annular boss 4, in the boss hole of described annular boss 4, be provided with a circle groove 5, be fixed with annular nylon washer 3 in groove 5, the aperture of nylon washer 3 is less than the aperture of tapped hole 2.
Be provided with some recesses 6 first-class point of the end face of annular boss 4, recess 6 is at least established three.Increase the area of contact between annular boss 4 and nylon washer 3 by recess 6, also increased pressure each other, strengthen frictional force, prevent that nylon washer from the situation such as spinning, ejecting and coming off groove 5 is interior, reduces link possibility loosening and that lost efficacy occurs to connect.
