Abstract
The utility model discloses an anti-theft and anti-loosening locking rivet, which comprises a rivet head and a rivet rod, wherein a mounting head is fixedly connected to the front end of the rivet head and has a screwing structure matched with a screwing tool; a twist-off part is formed at a fixed joint of the rivet head and the mounting head; a threaded structure is formed on the outer edge surface of the rivet rod; and an elliptical part which has a length of 3 to 10 times of a pitch is pressed on the rivet rod. The mounting head is arranged at the front end of the rivet head by the conventional fastener screwing tool; after the mounting head is mounted, the twist-off part is twisted off, so that riveting is realized; a mounting tool special for the rivet is not required, so that the mounting cost is saved; the elliptical part of the rivet rod is self-locked through elastic energy produced by deformation and interference when the rivet is screwed in through a thread; other rivet components of the conventional rivet are eliminated, so that the locking rivet has a simple structure, and the processing cost is saved; and furthermore, the locking rivet has relatively good anti-loosening and anti-seismic effects and can be widely applied to occasions in which the space on one side of a riveted object is finite.
Description
Technical field
The utility model relates to the fastening piece goods, the high-intensity rivet of especially on-disconnectable antitheft.
Background technique
The rivet of the world, domestic use all need be riveted the thing both sides basically at present has enough spaces just can rivet, and fashionable in limited field, riveted joint thing one side space, then need use the blind riveting rivet.The general rivet of forming by a plurality of assemblies that adopts of existing blind riveting rivet, this rivet processing technology is complicated, and cost of production is high, is unfavorable for producing in batches; Need specific rivet setting tool during the rivet installation, installation cost is high, and rivet value is low, is not suitable for high tenacity and connects a pair use.
The model utility content
The purpose of the utility model is to provide a kind of antitheft locking locking rivet, to solve rivet processing technology complicacy in the existing technology, the high and high problem of installation cost of cost of production.
For realizing above-mentioned purpose; The utility model adopts following technological scheme: the locking locking rivet of a kind of antitheft, comprise rivet head and rivet bar, and said rivet head front end is fixedly connected and is provided with installation head; Said installation head has and is used for the structure of screwing that cooperates with screwing tool; The fixed connection place of said rivet head and installation head forms and twists off the position, and the rivet bar outer edge surface is provided with worm structure, has the long oval position of (3～10) times pitch that is pressed on the rivet bar.
The rear end at said oval position and rivet bar afterbody distance are (2～5) times pitch.
Said rivet bar external thread diameter is between 2mm～12mm, and the minor axis external thread diameter of oval position cross section is that the circular external thread diameter of rivet bar deducts (0.1～0.8) pitch doubly.
Said rivet head be shaped as oval head or countersunk head or countersunk raised head or socket cap.
The said structure of screwing is interior six flowers, interior hexagonal or crosshead.
The locking locking rivet of a kind of antitheft of the utility model, the rivet head front end is provided with installation head, can directly install with common fastening piece screw-in instrument; To twist off after the installation position twist off can realize the riveted joint, do not need the specific setting tool of rivet, practiced thrift installation cost; The oval position of rivet bar; Oval position screw thread distortion when being screwed into rivet interferes formed elastic energy to realize self-locking, has saved all the other rivet assemblies of rivet in the existing technology, and is simple in structure; The locking torque size can be adjusted according to ellipsoidal structure; Practice thrift processing cost, and had locking preferably and the shock resistance effect, can be widely used in the limited occasion in riveted joint object one side space.

Embodiment
A kind of embodiment of the locking locking rivet of guarding against theft; As shown in Figure 1; The rivet head 3 of this locking locking rivet of guarding against theft is oval head; Its rear end is provided with the rivet bar of being processed by the metallic material of carbon steel plastic workings such as (alloyed steel, titanium alloy, refractory alloy, aluminum alloy or Cuprum alloys) 4; The periphery of rivet bar 4 has worm structure, and the diameter of thread of rivet bar 4 is arranged between 2mm～12mm, apart from screw thread tail end (2～5) times pitch place rivet bar is pressed into the long oval position 5 of (3～10) times pitch to rivet head extends; The circular external thread diameter that the cross section minor axis external thread diameter at oval position 5 is set to rivet bar 4 deducts (0.1～0.8) times pitch; Rivet head 3 front ends are convexly equipped with (or welding) and twist off position 2, twist off position 2 front ends and are welded with installation head 1, and the structure of screwing of installation head 1 has interior six flower shapes.The oval position 5 of the locking locking rivet distortion can be screwed into through screw thread time of guarding against theft interferes formed elastic energy to realize self-locking, and the size of locking torque is adjusted through regulating the screw thread radial-deformation.
Through installation head 1 rivet bar of rivet being screwed into needs the riveted joint position, and the riveted joint back will be twisted into two parts position 2 with certain moment and twisted into two parts, and installation head 1 comes off, thereby plays the riveted joint effect.Twist into two parts the size of moment, adjust, be greater than locking torque but twist into two parts moment through the shape and size of twisting into two parts position 2.
In other embodiments, the screwing structure and can also be interior hexagon of installation head, or cross or have the boss of parallel surface.
In other embodiments, twist off the position and can be convexly equipped with, be welded on the rivet head front-end face in the installation head rearward end.
In other embodiments, the shape of said rivet head can also be countersunk head or countersunk raised head or socket cap.
Claims (5)
