Abstract
The utility model provides a locking nut, which is characterized in that the middle part of the nut is provided with a threaded hole, and an axial screw hole is arranged on the end surface of the nut. The outer surface of the axial middle part of the nut is provided with a groove, and the groove is corresponding to the position of the screw hole. The screw hole is separated into a first screw hole and a second screw hole through the groove, a screw thread is arranged on the inner wall of the first screw hole, and the inner wall of the second screw hole is a smooth wall. The inside diameter of the second screw hole is equal to or larger than the crest diameter of the first screw hole, and two semicircular-ring budges are arranged on the end surface of the nut. The locking nut has the beneficial effect that two locking mechanisms are integrated onto the same one nut, so that the locking capability of the nut is further increased.
Description
Technical field
The utility model relates to a kind of nut, relates in particular to a kind of locking withdrawing nut.
Background technique
Existing locking withdrawing nut generally only has a kind of locking mechanism, and its locking effect is limited.
The model utility content
To the problem in the background technique; The utility model provides a kind of locking withdrawing nut, its improvement is: the nut middle part is provided with tapped hole, and nut end face is provided with axial screw hole; Nut shaft to the middle part outer surface be provided with groove; Groove is corresponding with screw hole location, and groove is divided into first screw hole and second screw hole with screw hole, and the inwall of first screw hole is provided with screw thread; The inwall of second screw hole is a smooth wall, and the internal diameter of second screw hole is equal to or greater than the Major Diam of first screw hole; Nut end face is provided with two semicircular ring convexities.
Said screw hole has two, and two screw holes are arranged on the nut symmetrically, and screw hole is corresponding one by one with groove.
The useful technique effect of the utility model is: two kinds of locking mechanisms are integrated on the same nut, further improve the lock ability of nut.
Description of drawings
Fig. 1, the utility model end face front view;
The A-A of Fig. 2, structure shown in Figure 1 is to cross section view (cylinder that is enclosed among the figure in the locking withdrawing nut is threaded axle).
Embodiment
The structure of the utility model is: the nut middle part is provided with tapped hole 1-1; Nut end face is provided with axial screw hole, nut shaft to the middle part outer surface be provided with groove 2-1, groove 2-1 is corresponding with screw hole location; Groove 2-1 is divided into the first screw hole 2-2 and the second screw hole 2-4 with screw hole; The inwall of the first screw hole 2-2 is provided with screw thread, and the inwall of the second screw hole 2-4 is a smooth wall, and the internal diameter of the second screw hole 2-4 is equal to or greater than the Major Diam of the first screw hole 2-2; Nut end face is provided with the protruding 2-5 of two semicircular ring.
During use; Nut is spun on the corresponding threaded axle, and threaded axle is provided with the corresponding groove with the protruding 2-5 of semicircular ring with the end face of nut contact, when nut screw into certain position; The part of the protruding 2-5 of semicircular ring is stuck in the groove of axle, nut can't be rotated; Nut sleeve is inserted a screw after on the axle from the second screw hole 2-4, one side, screw end is threaded with the first screw hole 2-2; Tighten screw; Nut on the screw is pressed in the end face of the second screw hole 2-4, makes second screw hole 2-4 structure generation deformation on every side, makes nut check;
Said screw hole has two, and two screw holes are arranged on the nut symmetrically, and screw hole is corresponding one by one with groove 2-1.
