Abstract
The utility model discloses a flange face hexagon check nut, including nut I and the nut II who sets up side by side, nut I includes the nut body and flange, nut II includes nut body i and the nut cover that is used for holding nut I, nut cover tip sets up to the conical surface, the conical surface is near connecting on the back of flange, the utility model discloses flange face hexagon check nut is through set up two hexagon nut side by side, and dual locking function has been played to the hexagon nut effect in back row on the hexagon nut's at front row flange face.
Description
Technical field
The utility model belongs to tying means, has the tensional element technical field of the screw thread that can make its fastening or tension, specifically relates to a kind of flanged surface hexagon check nut.
Background technique
In Fastener products, flanged surface hexagon nut is applied greatly and on a large scale because of simple, the fastening area of its structure.The usual structure of flanged surface hexagon nut is: comprise outer-hexagonal body, tapped hole is established in outer-hexagonal body, flanged surface is established in the lower end surface of outer-hexagonal body, some flanged surface hexagon nuts establish retaining decorative pattern in the bottom surface of flanged surface, make it that there is stopping function, the bottom surface of flanged surface is provided with center counterbore in the central position of retaining decorative pattern while arranging retaining decorative pattern, the cylindrical of center counterbore and the inner ring of retaining decorative pattern, the flanged surface hexagon nut of current band retaining decorative pattern does not possess other locking function, because adopt nylon spacer locking, tinsel locking and deformed threads locking all can increase the complexity of structure, all not too be applicable to large batch of production and application, and nylon spacer locking, tinsel locking and deformed threads are locked at the larger place of vibratory output, the effect of locking can not be brought, after dismounting several times, just there will be sliding tooth, nylon spacer locking was lost efficacy.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of flanged surface hexagon check nut, this flanged surface hexagon check nut is by being arranged side by side two hexagon nuts, the hexagon nut of rear row acts on the flanged surface of front-seat hexagon nut, play better occlusion locking effect, serve dual locking functions.
In order to achieve the above object, a kind of flanged surface hexagon check nut of the utility model, comprise the nut I and nut II that are arranged side by side, described nut I comprises nut body and flange, described nut II comprises nut body i and the nut cover for holding nut I, described nut cover end is set to the conical surface, and the described conical surface is near being connected on the back side of flange.
Further, the flange bottom of described nut I is provided with colored tooth.
Further, described colored tooth and nut I are screwed into direction and become α angle, and α angle is 8 ° ~ 15 °, and flower number of teeth amount is 24 ~ 36, and tooth depth is 0.2mm ~ 0.5mm.
Further, tapered ramp is provided with at the bottom of the tooth of described nut II checknut.
The beneficial effects of the utility model are:
The utility model flanged surface hexagon check nut is by being arranged side by side two hexagon nuts, and the hexagon nut of rear row acts on the flanged surface of front-seat hexagon nut, serves dual locking functions.
Accompanying drawing explanation
Fig. 1 is the sectional view of the utility model flanged surface hexagon check nut;
Fig. 2 is the structural representation of nut I in the utility model flanged surface hexagon check nut.
Reference character: 1-nut I; 2-nut II; 3-flange; 4-nut cover; 5-checknut; The 6-conical surface; 7-checknut; 8-flower tooth.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
Be illustrated in figure 1 the structural representation of the utility model flanged surface hexagon check nut, a kind of flanged surface hexagon check nut of the utility model, comprise the nut I1 and nut II2 that are arranged side by side, described nut I1 comprises nut body and flange 3, described nut II2 comprises nut body i and the nut cover 4 for holding nut I1, described nut cover 4 end is set to the conical surface 6, the described conical surface 6 is near being connected on the back side of flange 3, the present embodiment passes through by being arranged side by side two hexagon nut I1 and nut II2, nut I1 acts on labor cost by flange, nut II2 acts on the flange back side of front-seat nut I1 by the conical surface 6 of nut cover 4 end, nut II2 can help nut I1 to play locking effect by the conical surface 6, serve dual locking functions.
Further, flange 3 bottom surface of preferred described nut I1 is provided with colored tooth 8, the present embodiment by being provided with colored tooth 8, occlusion locking effect can be played, locking, anti-skidding effect can be played.
Further, preferred described colored tooth 8 is screwed into direction with nut I1 and becomes α angle, and α angle is 8 ° ~ 15 °, and flower number of teeth amount is 24 ~ 36, and tooth depth is 0.2mm ~ 0.5mm.
Further, be provided with tapered ramp at the bottom of the tooth of preferred described nut II2 checknut 7, this structure uses under vibration, can play locking effect.
What finally illustrate is, above preferred embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model by above preferred embodiment, but those skilled in the art are to be understood that, various change can be made to it in the form and details, and not depart from the utility model claims limited range.
