Abstract

PROBLEM TO BE SOLVED: To simplify mounting/demounting work by providing a flat bottom part in the lower of a screw part having a plurality of grooves, and providing the groove in an intermediate screw part and a movable hexagonal part. SOLUTION: In the intermediate of a flat bottom part 8 in a screw part 2, the screw part 2 threaded by one turn is combined into one unit and with a groove 1 is provided in its upper part. At the time in use, a bolt 6 is inserted to a part desired to be tightened, a movable hexagonal part 3 is inserted to the bolt 6 at a stroke, and by pressing the movable hexagonal part 3, the movable hexagonal part 3 is turned to the right in the case of a right hand screw. In the case of a left hand screw, when the movable hexagonal part is turned to the left, the screw part 2 faces toward the center to move, and a thread of the bolt 6 and a thread of the movable hexagonal part 3 are united to be locked. Further the nut can be used even in an existing bolt 6 in use and also can be used in metal, plastic, and the like.

Description

Detailed Description of the Invention

[Field of Industrial Application] This invention is a nut which can be easily attached and detached.

[Prior Art] Conventional nuts had to be installed from the beginning, and had to go to the place where it was desired to tighten them all at once, and the nut also had a lid.

[Problems to be solved by the invention] This has the following drawbacks. (A) I couldn't attach the nut to the bolt smoothly from the beginning. (B) I couldn't take the nut all at once to where I wanted to tighten it, and it was also with a lid. (C) It took too long. The present proposal has been made to eliminate these drawbacks.

[Means for Solving the Problem] The screw portion (2) is a groove (1) cut into a plurality of pieces, and the tab of the screw portion (2) is a taper (9). The lower part of the screw part (2) is a recess (4). Screw part (2)
The lower portion of the outer periphery of the movable hexagonal portion (3) is a recess (4), and the outer periphery of the movable hexagonal portion (3) is hexagonal. The inside of the movable hexagonal portion (3) is tapered (9), and the recess (4) is provided between the taper (9) and the taper (9). The outer periphery of the screw portion (2) and the movable hexagonal portion. (3) having an uneven portion (5) inside. A circular flat bottom portion (8) is provided in the lower portion of the screw portion (2), and a screw portion (2) for one rotation is placed in the lower portion inside the movable hexagonal portion (3) in the middle thereof. Thus, the groove (1) is provided. It is a simple tightening nut having the above configuration.

[Operation] A nut that can be attached and detached by inserting the bolt into a place where it is to be tightened and passing the nut through the bolt all at once, and using plastic or metal, which can also be used for the bolts that have been used so far.

[Embodiment] An embodiment of the present invention will be described below. The threaded portion (2) having the groove (1) cut into 3 to 4 is provided with a threaded portion (2) for one rotation at the entrance of the movable hexagonal portion (3). Movable hexagonal part (3) in which a screw part (2) having a screw for one rotation is united in the middle of the flat bottom part (8) of 2) and a groove (1) is provided on the upper part thereof. The screw part (2) is free in the groove (1), and the screw part (2) is prevented from falling off from the movable hexagonal part (3). From the movable hexagonal part (3), the screw part (2) is slightly protruding.

The present invention has the above-mentioned structure. When using this structure, the bolt (6) is inserted into the hole at the place to be tightened, and the movable hexagonal part (3) is passed through the bolt (6) all at once. If you press () and turn the movable hexagonal part (3) to the right for the right-hand screw, or to the left for the left-hand screw, the screw part (2) will move toward the center, and the screw part (2 ) Moves, and the screw of the bolt (6) and the screw of the movable hexagonal part (3) are united and locked. Moreover, it can be used with the bolts (6) that have been used up to now, and also with metals, plastics, etc.

[Effect of the device] You can easily lock the nut by tightening it to the place you want to tighten. Easy to install and remove. It can be manufactured with one less process than the conventional nuts,
Moreover, you can easily install the nut. It can be manufactured and used with plastic, metal, etc. It can also be used with the bolts that have been used up to now. It can be installed and removed accurately in a short time.
