Abstract
The utility model relates to a self-locking nut comprising a common nut, an embedded nylon body, an embedded groove and an embedded nylon loop. The embedded nylon body is disposed on a tail part of the common nut, and the inner side of the embedded nylon body is provided with the embedded groove. The embedded nylon body can be embedded in the embedded groove after the deformation. A deformation force in the axial direction can be applied on the tail part of the common nut, thereby the common nut can be deformed a little bit in the axial direction, and the embedded nylon body can be deformed to achieve the self-locking object. By adopting the structure of the self-locking nut provided in the utility model, the bolt can be used repeatedly, the locking force can be more reliable, the production costs of equipment can be reduced, and the resources can be saved.
Description
Technical field
The utility model relates to a kind of nut, particularly a kind of inserted self-locking nut.
Background technique
Aboard; All adopted hexagonal self-locking nut and bolt that equipment is connected on the body, in complex operating environment, the hexagonal self-locking nut still maybe be because the locking torque disappearance in the past; Lose the locking effect; The equipment of connection is come off from body, thereby cause the afunction of equipment, produce security incident.Therefore the coupling mechanism force and the reliability that improve self-locking nut become urgent problem.
The model utility content
The utility model technical problem to be solved provides a kind of self-locking nut that improves the mechanized equipment connection reliability.
A kind of self-locking nut, this self-locking nut comprise plain nut, inlay nylon body, mosaic groove, inlay nylon ring; Inlay the afterbody that nylon body is positioned at plain nut, dug mosaic groove, inlay nylon ring and embed in the mosaic groove through the distortion back in the inside of inlaying nylon body; Afterbody at plain nut applies axial deformation pressure then, lets it produce axial micro-deformation, makes to inlay nylon ring generation deformation and reach oneself's locking.
The utility model self-locking nut is assemblied in the self-lock force that back distortion nylon ring produces on the bolt can be firmly locked on bolt with nut; Common loosening phenomenon when having avoided regular screw threads to connect; And, can also avoid other normal locking phenomenon that occurs in self-locking nut assembling back through the locking of distortion nylon ring.Bolt can be repeatedly used after the structure of employing the utility model self-locking nut, has saved equipment manufacture cost and resource greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model self-locking nut;
Embodiment
Can find out that from Fig. 1 the related inserted self-locking nut of the utility model comprises: plain nut 1, inlay nylon body 2, mosaic groove 3, inlay nylon ring 4.
The utility model is to inlay nylon body 2 in plain nut 1 afterbody increase; Inlay nylon body 2 inner excavation mosaic grooves 3; Plain nut 1 shapes the back and is embedded in nylon ring 4 at mosaic groove 3, inlays nylon ring 4 and could embed after through distortion, applies axial deformation pressure at the afterbody of plain nut 1 again after the embedding; Let it produce axial micro-deformation, reach oneself's locking thereby let it produce deformation like this.The width of mosaic groove 3 and the degree of depth are confirmed according to the size of inlaying nylon ring 4, inlay the size of nylon ring 4 and are then confirmed by the coupling mechanism force size of nut as required.
The utility model is taked cheaply, and machining process carries out overall structure processing; Cut out the groove of inlaying nylon ring at inlaid body part endoporus place then; Groove dimensions is confirmed according to the coupling mechanism force size that test draws; When to be assembled nylon ring is inlaid into body, then inlaid body structure division afterbody is exerted pressure.After the assembling of the self-locking nut of other structure, tend to cause bolt not reuse, and the bolt in the utility model is repeatedly reusable because of after the self-locking distortion bolt being destroyed.The utility model is simple in structure, and processability is good, and product is safe and reliable, can be popularized and applied to various mechanical industries.
Claims (1)
1. a self-locking nut comprises plain nut (1), it is characterized in that: this self-locking nut also comprises to be inlayed nylon body (2), mosaic groove (3), inlays nylon ring (4); Saidly inlay the afterbody that nylon body (2) is positioned at plain nut (1), dug mosaic groove (3), inlay nylon ring (4) and embed in the mosaic groove (3) through the distortion back in the inside of inlaying nylon body (2); Afterbody at said plain nut (1) applies axial deformation pressure, lets it produce axial micro-deformation, makes to inlay nylon ring (4) generation deformation and reach oneself's locking.
