Description

BOLT AND NUT
Technical Field
The present invention is related to a bolt and a nut, and in particular, to a structure of bolt and nut enabling a bolt and a nut to be easily coupled or separated with a single rotating movement regardless of a length required for coupling or separating the bolt and the nut.
Background Art In general, bolts and nuts are widely used in daily lives apart from the mechanical field alone. While their major function is to couple and fix two members in machinery, architectural structures or in other daily necessities, bolts and nuts are also widely used to dissemble or separate coupled fittings, daily necessities or architectural structures. Thus, the bolts and nuts are commonly used in our daily lives or industries. Since the bolts and nuts comprise screw portions only, however, they can be coupled or separated only through continuous rotation either in clockwise or anti-clockwise direction along with the screw portion once after contacting the female screw portion inside of the nut with the tip of the male screw portion of the bolt. Therefore, the bolts and nuts can be completely coupled or separated only by rotating them in clockwise or anti-clockwise direction. In other words, the conventional bolts and nuts can be coupled or separated through rotational movement only, thereby requiring a considerable amount of time and effort. For this reason, expensive electric automatic tools are mainly used recent days for coupling or separation of bolts and nuts. Further, the conventional bolts and nuts have caused inconvenience in plumbing, dissembling or assembling works. Besides, bolts become useless once the tips of their screw portions are crumbled. Disclosure of Invention
It is, therefore, an object of the present invention to provide a structure of the bolt and nut with an awareness of the above problems caused due to the structure of the conventional bolt and nut having a structure composed of screw portions alone and necessitating continuous rotating movement until reaching a predetermined position of the nut for coupling with the bolt.
To achieve the above object, there is provided a structure of a bolt and a nut enabling the bolt and nut to be easily coupled or separated with a single rotating movement regardless of a length of the bolt and nut to be coupled or separated.
The structure of a bolt and a nut according to the present invention is compatible with the conventional bolt and nut.
The bolt and the nut according to the present invention comprise: a bolt 11 having screw portions 14 formed in a predetermined area of a male screw in a longitudinal direction, and hollow portions 15 formed in a longi dinal direction by cutting the surface of the male screw portion; and a nut 12 having screw portions 14 formed in a predetermined area of a female screw in a longitudinal direction, and hollow portions 15 formed by cutting inside of the female screw portion of the nut 12 in a longitudinal direction to correspond to the bolt 11. Preferably, a pair of hollow portions 15 and screw portions 14 is formed in the bolt 11 and the nut 12 to face each other.
In order to couple or separate the bolt and the nut according to the present invention, the screw portions 14 and the hollow portions 15 should be located in the bolt
11 and the nut 11 so that the hollow portions 15 and the screw portions 14 of the nut 12 may correspond to the screw portions 14 and the hollow portions 15 of the bolt 11. Then, the bolt 11 and the nut 12 can be easily coupled without rotating the bolt 11 or the nut 12 until reacMng a predetermined position.
The method of coupling or separating the bolt and the nut according to the present invention comprises the steps of: forming the screw portions 14 in the bolt 11 so as to face the hollows of the nut 12; forming the hollows 15 in the bolt 11 so as to face the screw portions 14 in the nut 12; pushing or pulling the bolt 11 or the nut 12 until the position of enabling the bolt 11 and the nut 12 to be directly coupled or separated without rotation.
Thus, the method of coupling or separating the bolt and the nut according to the present invention enables the bolt and the nut to be easily coupled or separated without reciprocal rotation but with straightforward pushing or pulling movement and a rotating movement.
