Abstract
The utility model discloses a hay mower nut which comprises a nut body and a sleeve ring. A radial threaded hole is formed in the middle of the nut body, a movable cavity is formed in one end of the nut body in the tightening direction, a protruding ring is arranged on the inner side of the sleeve ring, the protruding ring is arranged in the movable cavity, the sleeve ring can move relative to the nut body, a groove ring is arranged on the surface of the nut body, friction force is increased after a bolt is tightened, loosening is not prone to happening, and the outer side and the inner side of the sleeve ring are of an arc face structure. According to the design scheme, after the position of the nut body is adjusted through the movable sleeve ring, the nut body and the movable sleeve ring are locked, the contact face between the nut body and a component is increased through the arc face design of the sleeve ring, locking force is larger, the groove ring is arranged on the surface of the nut body, the friction force is increased when the nut body and the bolt are locked, and loosening is not prone to happening after the nut body and the bolt are locked.
Description
Technical field
The utility model belongs to field of mechanical technique, is specifically related to a kind of mowing machine nut.
Background technique
Nut is more and more widely used in industry-by-industry as fundamental parts, the fastening piece that traditional nut has internal thread and is used in conjunction with bolt, along with industrial expansion, some nuts cannot be used in SPECIAL MACHINE, the axial locking nut of picture mowing machine, during due to connection, surface has radian, and traditional nut landscape surface cannot well be fitted with it and be formed locking, it is not very stable making to coordinate, easily loosening.
Summary of the invention
The purpose of this utility model is to design a kind of mowing machine nut.
To be solved in the utility model is that existing nut connects unstable easily loosening problem.
The technical solution of the utility model is: comprise nut and the collar, in the middle of described nut, be provided with radial screw bore, described nut screwing clamping direction one end is provided with movable chamber, and described collar inner side is provided with bulge loop, and bulge loop is installed in movable chamber, collar nut activity relatively.
Described nut surface is provided with groove ring.
Described collar outside and inner side are globoidal structure.
Adopt design proposal of the present utility model, by the locking with it more later of movable loop adjusting nut body position, the cambered surface design of the collar has increased the surface of contact between nut and parts, make coupling mechanism force larger, the surface of nut is also provided with groove ring, when with locked with bolts, increase frictional force, made to be more not easy to become flexible after locking.
The utlity model has nut stable connection and be not easy loosening advantage.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1: the utility model comprises nut 3 and the collar 1, in the middle of described nut 3, be provided with radial screw bore 2, described nut 3 tightening direction one end are provided with movable chamber 6, and the described collar 1 inner side is provided with bulge loop 5.
As shown in Figure 2: described bulge loop 5 is installed in movable chamber 6, the collar 1 nut 3 activities relatively, described nut 3 surfaces are provided with groove ring 7, bolt has increased frictional force after tightening, be difficult for loosening, the described collar 1 outside and inner side are globoidal structure 4, adopt design proposal of the present utility model, by the locking with it more later of movable loop adjusting nut body position, the cambered surface design of the collar has increased the surface of contact between nut and parts, make coupling mechanism force larger, the surface of nut is also provided with groove ring, when with locked with bolts, increase frictional force, make to be more not easy to become flexible after locking.
