Abstract
The utility model discloses an anti-rotation rivet-turning type self-locking nut, which comprises a nut with an internal screwed hole. A boss is arranged on the nut. An outer cylinder on one side of the nut and close to the boss is provided with anti-rotation straight teeth. The nut at the front end of the anti-rotation straight teeth is provided with a thin-wall outer cylinder used for turning over a rivet. A necked outer cylinder is arranged on the other side of the nut and far away from the boss. When the anti-rotation rivet-turning type self-locking nut is in use, the anti-rotation straight teeth on one side of the nut are inserted into the matrix of a member 7 to be connected. The thin-wall outer cylinder of the nut is expanded and deformed through the conventional flaring mode and the nut is flanged so as to be buckled to the member 7 to be connected. Therefore, the nut assembled with the member 7 to be connected through riveted joint is prevented from falling off during usage. The anti-rotation rivet-turning type self-locking nut has the advantages of simple structure, convenient usage and reliable working performance. Meanwhile, the nut will not fall off from a member to be connected during usage.
Description
Technical field
The utility model relates to a kind of anti-rotation and turns over riveting formula self-locking nut, belongs to technical field of fastening.
Background technique
In mechanical fasteners connects, laborsaving in order to assemble, on nut, often all be provided with and pull the structure that kinks.But be used in the bigger occasion of some vibrations,, must prevent that part from becoming flexible, skidding through self-locking so because vibration can cause nut loosening.So, must prevent that part from coming off through riveted joint in some special occasions.And existing nut or self-locking nut structure are not convenient for itself and connected piece are riveted very much; Therefore in the special use occasion that need nut and connected piece be riveted together, existing nut or self-locking nut structure just can not satisfy the needs of this use.
Summary of the invention
The purpose of the utility model is: a kind of simple in structure, easy to use, reliable operation is provided and can turn over riveting formula self-locking nut from the anti-rotation that connected piece comes off in use, to overcome the deficiency of existing technology.
The utility model is to constitute like this: a kind of anti-rotation of the utility model is turned over riveting formula self-locking nut; Comprise the nut that is provided with interior threaded hole; On nut, be provided with a boss (1); On nut outer cylinder, be provided with anti-rotation straight-tooth (2), on the nut of anti-rotation straight-tooth (2) front end, be provided with the thin-walled outer cylinder (3) that is used to turn over riveting, on the nut of boss (1) opposite side, be provided with closing in outer cylinder (4) near boss (1) one side.
Above-mentioned anti-rotation straight-tooth (2) is evenly distributed on the outer cylinder of nut.
On above-mentioned closing in outer cylinder (4), being uniformly distributed with 1～4 along the circumference can make the internal thread of nut produce the extrusion-deformation point (5) of radial protrusion distortion to the nut center.
Owing to adopted technique scheme, the utility model is provided with the anti-rotation straight-tooth at an end of nut, and when using the utility model, this anti-rotation straight-tooth can insert in the matrix of connected piece, thereby prevents that nut rotates when bolt is twisted like nut; Simultaneously; The utility model is provided with on nut and is used to turn over the thin-walled outer cylinder that riveting is used, during use, through the mode to this thin-walled outer cylinder enlarging; Can the utility model be riveted on the connected piece, thereby can prevent effectively that nut from working in the big environment of vibration the time and come off; The utility model is provided with closing in outer cylinder and extrusion-deformation point at the other end of nut; Through of the extruding of extrusion-deformation point to the closing in outer cylinder; Can make the internal thread of nut that distortion among a small circle takes place; Thereby the generation self-lock force makes nut play locking effect, is specially adapted to be used in some special occasion.So, the utility model compared with prior art, the utility model not only has advantage simple in structure, easy to use, but also has reliable working performance and in use can be from advantages such as connected piece come off.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is that the utility model is assemblied on the connected piece, and is connected the structural representation when using with bolt.
Being labeled as in the accompanying drawing: 1-boss, 2-anti-rotation straight-tooth, 3-thin-walled outer cylinder, 4-closing in outer cylinder, 5-extrusion-deformation point, 6-bolt, 7-connected piece.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify, but not as any restriction to the utility model.
The embodiment of the utility model: it is as shown in Figure 1 that a kind of anti-rotation of the utility model is turned over the structural representation of riveting formula self-locking nut; This anti-rotation is turned over riveting formula self-locking nut and is comprised the nut that is provided with interior threaded hole; During making; On nut, produce a boss 1 simultaneously, on nut outer cylinder, produce anti-rotation straight-tooth 2 then, anti-rotation straight-tooth 2 is evenly distributed on the outer cylinder of nut near boss 1 one sides; On the nut of anti-rotation straight-tooth 2 front ends, produce the thin-walled outer cylinder 3 that is used to turn over riveting; On the nut of boss 1 opposite side, produce closing in outer cylinder 4 then, mode through extruding is uniformly distributed along the circumference on closing in outer cylinder 4 and squeezes out 1～4 internal thread that can make nut produces extrusion-deformation point 5 from the radial protrusion distortion to the nut center simultaneously.During making, preferably can adopt traditional heat treatment mode, the closing in outer cylinder 4 of nut is heat-treated enhancement process, more can make nut play good locking, locking effect so in use.
When using the utility model; As shown in Figure 2, earlier insert the anti-rotation straight-tooth 2 of nut one end in the matrix of connected pieces 7 after, adopt traditional enlarging mode then; Make the thin-walled outer cylinder 3 of nut swell and deform; And turn over riveting and be buckled on the connected piece 7, thereby the nut riveted joint is assemblied on the connected piece 7, can prevent that like this nut from coming off in use.After riveted joint is good, can bolt 6 be turned in the riveting formula self-locking nut by the anti-rotation that routine is screwed into the utility model.
