Abstract
The utility model relates to a nut. The utility model comprises nuts and wheel shafts, wherein, each nut is provided with a locking structure, and the rear wheel shaft is provided with symmetric rectangular holes. As for the locking structure, fasteners are arranged on the end surface of the nut, one end of each fastener is provided with a convex matching the rectangular holes of the wheel shaft, a peaking shaft connected with the nut is arranged on the middle part of the fastener, and a spring is arranged on the peaking shaft. The utility model is mainly used on the rear wheel shaft of a bicycle. When the utility model is used, the nuts are screwed on both ends of the wheel shaft, and when the convex suitably matches the rectangular hole on the wheel shaft, the fastener is pressed, so that the convex is fastened in the rectangular hole, thus preventing the nut from being loosened. The utility model has the advantages of simple structure, reasonable design, practicability, convenience, etc.
Description
Technical field
The utility model relates to a kind of nut.
Background technique
Screw bolt and nut is usually used in combination fixing of two or more parts.But when it was used in the environment of vibration, regular meeting made nut loosening.Though between traditional bolts and nuts, be provided with locking device, the structure more complicated.Because vibratory output is bigger, especially the student does not note by bike the time very much, in case can cause unnecessary danger after nut comes off in general bicycle rear shaft upper cap nut.
Summary of the invention
The utility model provides a kind of reasonable in design, simple in structure, practical and convenient lock nut at the deficiencies in the prior art.
The utility model is achieved through the following technical solutions:
The utility model comprises nut and wheel shaft, wherein, is provided with locking mechanism on nut, is provided with the square opening of symmetry on rear-wheel spindle.Described locking mechanism is that the end face at nut is provided with button, and an end of button is provided with the projection that cooperates with the wheel shaft square opening, and the button middle part is provided with spring and is connected with nut.
The utility model is mainly used on the bicycle rear shaft, during use, nut is screwed in the two ends of wheel shaft, when projection and square opening on the wheel shaft cooperate when suitable, press button projection is stuck in the square opening, thereby prevented getting loose of nut, have simple in structure, reasonable in design, advantage such as practical and convenient.
