Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clip nut capable of holding a bolt instead of a general nut.

[0002]

BACKGROUND OF THE INVENTION Many structures have a male threaded bolt in the peripheral wall of the cylinder and a female thread in the central hole to connect the various members. 6
Square or square nuts are often used, but it takes a lot of time and effort to fit the nuts to the bolts and tighten them, and to weld or enamel the tightened parts to prevent them from loosening over time. It takes time and the efficiency is not improved, which is also a cause of increasing the construction cost. It is an object of the present invention to overcome the drawbacks of the conventional methods and to provide a clip nut that can be adapted to any bolting operation.

[0003]

In order to achieve the above object, the clip nut of the present invention has an elongated rectangular elastic steel plate folded back in the middle so as to be doubled, and a bolt is provided at the center of each of the upper plate and the lower plate. The clip nut body is provided with a gourd-shaped through hole that corresponds to the upper and lower plates, with a play hole that can penetrate with plenty of space and a small hole where the bolt can be locked. It is configured by combining with a base plate that is used.

Here, in order to prevent the clip nut body from slipping and being disengaged from the bolt after being mounted on the bolt,
A pair of standing claws that engage with the upper edge of the base plate may be provided on both sides of the upper plate by cutting. Furthermore, both side edges of the base plate serve as rising walls that prevent displacement of the combined clip nut body. Is desirable. In addition, the rising walls on both sides of the base plate are formed in a hook shape so as to surround both edges of the clip nut body, and a narrow notch for temporarily fixing the standing claw of the clip nut body upper plate to the horizontal portion. If it is provided, it is convenient for storage. Further, in order to secure the locking with the bolt, the thickness of the lower surface plate of the clip nut main body may be increased outward through the inclined surface only in the portion of the through hole having the small hole.

In the clip nut of the present invention constructed as described above, after the base plate is sandwiched between the upper plate and the lower plate, the play holes of the gourd-shaped through holes of the upper plate and the lower plate and the base plate are formed. After aligning the positions of the bolt through holes and passing them through the bolts, the clip nuts are displaced to lock the small holes to the threads of the bolts.

[0005]

Embodiments of the clip nut of the present invention will be described below with reference to the drawings. In each drawing, 1 is a clip nut body, and 5 is a base plate to be combined with the clip nut body 1. The clip nut main body 1 is formed by folding an elongated rectangular elastic steel plate in the middle to form a double plate of an upper plate 2 and a lower plate 3, and a base plate 5 can be sandwiched between them. At the center of each of the upper plate 2 and the lower plate 3, there is a play hole 4a through which the bolt 7 can pass with a margin and a small hole 4b into which the bolt 7 can be locked.
A continuous gourd-shaped through hole 4 is provided correspondingly. Also, on both side edges 2a, 2a of the upper plate 2, the base plate 5
A pair of standing claws 2b, 2b that engage with the upper edge 5a are provided by cutting to ensure locking when the clip nut body 1 is locked to the bolt 7 as shown in FIG. .

The base plate 5, which is also a rectangular steel plate, has a through hole 6 having a diameter slightly larger than that of the bolt in the center, and both side edges are both side edges 2 of the upper plate 2 of the clip nut body.
The hook-shaped rising walls 5b and 5b surrounding a and 2a are formed to prevent displacement of the clip nut body 1 when combined. Further, the horizontal portions 5 of the rising walls 5b and 5b are
b ′ and 5b ′ are provided with thin grooves 5c and 5c by notches, and as shown in FIG. 3A, the tips of the standing claws 2b and 2b of the clip nut upper plate 2 are shallowly fitted and engaged to form the base plate. 5
By storing and transporting the clip nut body 1 and the clip nut body 1 in a state of being lightly engaged with each other in advance, the work efficiency can be improved without the need to individually search for both parts at the time of use.

The method of using the clip nut of the present invention constructed as described above is as follows: the upper plate 2 and the lower plate 3 of the clip nut body.
After the play hole 4a of each through hole and the through hole 6 of the base plate 5 are aligned and passed through the bolt 7, the folded back portion 1a of the clip nut body 1 is tapped lightly with a hammer or the like. Only the bolt 7 moves,
It moves from the play hole 4a and fits into the small hole 4b.
Lock the entire clip nut onto the bolt as shown in. At that time, the standing claws 2a of the upper plate 2 of the clip nut body,
2a engages and fixes the upper edge 5a of the base plate 5, and the clip nut body 1 does not return.

Further, as another embodiment, as shown in FIGS. 4A and 4B, the bottom plate 3 of the clip nut body 1 is
About the through hole 4, the portion 3a having the small hole 4b,
When the thickness is increased outward through the inclined surface 3b, the clip nut is passed through the bolt and temporarily fixed at the intermediate portion of the through hole 4, and then when the clip nut body 1 is moved by striking the folded portion 1a, the clip nut body 1 is moved. The thread of the bolt engaged with the movement rides on the thick portion 3a of the lower plate 3 and presses the lower plate 3 inward to elastically adhere to the base plate 5 and the upper plate 2. The locking with the bolt is further strengthened. It may be provided on the part, and a highly convenient method can be taken depending on the usage method.

[0009]

The clip nut of the present invention constructed as described above is mounted by simply tapping the rear part while passing through the through hole to be fastened to the bolt, so that it is as laborious as a conventional nut. It is easy, extremely easy to work with, and efficient. Further, as shown in FIG. 2 (C), the engagement with the bolt is to be locked at three points of the upper plate and the lower plate of the clip nut body and the base plate, so that the mounting is extremely reliable, There is no need to weld or apply enamel after crimping as with conventional nut stops. Further, when the clip nut main body is provided with the standing claws, the base plate and the clip nut main body will not be displaced from each other after the bolt is mounted, and the locking will not be loosened. Since the standing claws of the clip nut body are locked in the narrow groove for transportation and storage, there is no loss in the time to search for and combine each when using them, compared to when they are separated Is big.
