Embodiment Construction

[0011] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0012] figure 1 , figure 2 , image 3 Showing the basic embodiment of the present invention, there is a vertical circular hole (2) at the center of the end of the bolt main body (1), and two or more thin holes are vertically opened on the outer side of the bolt thread with the center of the circle as the axis and through the diameter of the bolt. Sew (3).

[0013] figure 1 , figure 2 , image 3 Show the implementation method and process of the present invention, after the bolt body (1) and the nut (2) are fastened in place to the workpiece, use a metal taper (5) to align the center of the round hole (2) at the end of the bolt and knock moderately, so that The slits (3) at the ends of the bolts are equally open and expanded. The slit (3) at the bolt end can be expanded to make the bolt thread tightly press the nut inner teeth, and the ...

Abstract

Aiming at the improvement of a bolt end, a vertical circular hole (2) is drilled in the circle center of the bolt end, and two or more slits (3) are vertically formed in an outer side of a bolt threadby taking a circle center as an axis in the mode of penetrating the diameter of a bolt. A round hole (2) at the bolt end is properly knocked by a metal conical drill rod (5), so that the slits (3) are expanded, and the problem that a nut is easy to loosen after being installed is thoroughly solved. According to the invention, the bolt end is modified without additionally adding materials, the operation is simple and convenient, the reliability is strong, the application is wide, the nut can never loosen, and the opening nut is particularly suitable for engineering construction without considering secondary dismounting and the permanent fixation of mechanical equipment after the bolt and the nut fasten a workpiece.

Description

technical field [0001] The invention relates to a bolt, in particular to a split bolt which can prevent the nut from loosening. [0002] technical background [0003] Bolts and nuts are widely used fastening accessories. Bolts and nuts are basically used in the fixing of mechanical equipment, especially railway tracks and bridges and other facilities. However, due to frequent vibrations during use, the nuts will loosen by themselves, which can easily cause failure and damage to facilities and equipment. In order to solve this problem, many people have made many improvements in preventing the nut from loosening, such as: adding a lock washer and setting a lock nut with a combined structure. The above improvement measures all need to add additional materials without exception, and the technology is difficult, the structure is complex, the cost is high, and the anti-loosening effect is difficult to achieve the best condition. Contents of the invention [0004] The object of ...
