CN201448334U - Set nut - Google Patents

Abstract

The utility model relates to a set nut which is provided with a hexagon nut block, wherein the surface of the inner ring of the nut block is provided with an inner thread; the width of the inner thread is 3/5 of the height of the nut block; the remained part that is obtained by removing the inner thread from the inner ring of the nut block is embedded into a nylon ring; one side of the nut block, positioned at the nylon ring, is extended with an iron ring which is used for fixing the nylon ring at the inner ring of the nut block; and the iron ring and the nut block are in an integrated structure. The set nut has novel design, simple structure and very convenient production and manufacturing, and greatly reduces the production cost.

Description

A kind of locknut

Technical field

The utility model relates to a kind of locknut.

Background technique

The working principle of nut is to adopt the frictional force between the nuts and bolt to carry out self-locking, but the reliability of this self-locking in dynamic load will reduce.We will take some locking measures in some important occasions, guarantee the reliability of nut check, are exactly wherein a kind of locking measure with locknut wherein.

Locknut also has two kinds, and a kind of is to be screwed on the same support bolt with two the same nuts, additional screw-down torque between two nuts, and it is reliable to make bolt connect; Another kind is special-purpose lock nut, need and a kind of can the use together by check washer, special-purpose lock nut is not a hexagon nut, but round nut in, have 6 breach on the circumference of nut, these six Point of Strength that breach is a tightening tool are again the places that snaps in of check washer bayonet socket, these two kinds locking mode structure more complicated, cost of production is higher.

The model utility content

The utility model provides a kind of locknut, to solve locknut complex structure, the technical problem that cost is too high.

The technological scheme that its technical problem that solves the utility model adopts is: a kind of locknut, has the six-sided nut piece, the nut block inner peripheral surface offers internal thread, the width of described internal thread is 3/5 of a nut block height, the residue position embedded a nylon ring after the nut block inner ring was removed screw thread, nut block is positioned at nylon ring one epitaxial lateral overgrowth and stretches the iron hoop that nylon ring is fixed on the nut block inner ring is arranged, and this iron hoop and nut block are structure as a whole.

The utility model modern design, simple in structure, production and processing is very convenient, greatly reduces cost of production.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a plan structure schematic representation of the present utility model;

Fig. 2 is that A of the present utility model is to schematic cross-section;

Wherein: 1, nut block, 2, screw thread, 3, nylon ring, 4, iron hoop.

Embodiment

With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.

As shown in Figure 1, a kind of locknut, has six-sided nut piece 1, nut block 1 inner peripheral surface offers internal thread 2, the width of described internal thread 2 is 3/5 of nut block 1 height, nut block 1 inner ring removes that the residue position embeds a nylon ring 3 behind the screw thread, and nut block 1 is positioned at nylon ring 3 one epitaxial lateral overgrowths and stretches the iron hoop 4 that nylon ring 3 is fixed on nut block 1 inner ring is arranged, and this iron hoop 4 is structure as a whole in nut block 1.

The utility model modern design, simple in structure, production and processing is very convenient, greatly reduces cost of production.

Claims (1)

1. locknut, has six-sided nut piece (1), nut block (1) inner peripheral surface offers internal thread (2), it is characterized in that: the width of described internal thread (2) is 3/5 of nut block (a 1) height, the residue position embedded a nylon ring (3) after nut block (1) inner ring was removed screw thread, nut block (1) is positioned at nylon ring (3) one epitaxial lateral overgrowths and stretches the iron hoop (4) that nylon ring (3) is fixed on nut block (3) inner ring is arranged, and this iron hoop (4) is structure as a whole with nut block (1).
