Abstract

The utility model relates to a fast fixture device for screw bolts and nuts. Both sides of the screw bolt (2) are opened with two grooves in a split way. Internal teeth (4) of the nut (1) forms two projecting parts which are anastomosis with grooves. The internal teeth (4) of the nut (1) is aimed to the grooves of the screw bolt (2). The nut (1) can directly move to any position of the screw bolt (2) without turning the nut (1). The nut is tightly screwed. (1) A purpose-made check washer is sheathed in the gap between the nut (1) and the screw bolt (2). The using process is flexible, convenient and quick. The structure of the locknut and special tools thereof is also suitable for the tools such as a bench clamp, a pipe bench vice, a wrench, etc.

Description

Fast fixture device for screw bolt, nut

The utility model relates to the quick securing means of a kind of bolt, nut.

Existing bolt, nut utilize the design of spiral usually, for long bolt, or common bench vice, pipe tong, wrench etc., in the using process, need rotation repeatedly, directly end correct position to screw nut again, use inconvenience, and expend man-hour.

The purpose of this utility model provides the quick securing means of a kind of bolt, nut.In use, needn't rotate repeatedly, allow nut on bolt, move, move to desired location and screw again, adopt check washer to strengthen fastening effect then.Adopt the instruments such as bolt, nut or bench vice, pipe tong, wrench of this kind structure, can reduce labor intensity, improve work efficiency, use fast, convenient.

The utility model is realized in the following manner:

Split two grooves in the both sides of the body of bolt, the internal tooth of nut is protrusion two-part, and the projection size is close with the groove position.With projection alignment slot position, nut just can move on bolt, moves to desired location fastening nut again, and the internal tooth of nut and the toothed portion that has of bolt are meshed.There are two spaces in combination behind bolt, the nut screwing clamping, and adopting has the check washer of boss to be enclosed within on the bolt, and projection section is inserted in the gap of combination, can prevent loosening between bolt, nut.Whole process is quick, easy, firm.

Now the utility model is described in further detail in conjunction with the accompanying drawings:

Fig. 1 is the utility model bolt arrangement figure.

Fig. 2 is along Figure 1A-A line sectional view.

Fig. 3 is the utility model nut structure figure.

Fig. 4 is along Fig. 3 B-B line sectional view.

Fig. 5 is the utility model check washer structural drawing.

Fig. 6 is the structural drawing that the utility model nut can move on bolt.
