Abstract

PURPOSE:To rapidly bond a male screw with the similar member by cutting and forming a plate material in such a manner that the center side ends of radially disposed locking pieces are free ends, and the outer circumferential side ends are continued to a base part. CONSTITUTION:A base part 2, locking pieces 3, and notch parts 4 are integrally pressed and molded on a metal plate material such as steel and spring steel. Only the outer circumferential side ends 3a continued to the base part 2 is left uncut and stood, and the center side ends 3b are made into free ends to form the locking pieces 3, so that they can be spirally fitted to a male screw. Thus, the male screw and the similar member can be rapidly bonded to each other by the elasticity of the locking pieces 3.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a coupling device and a coupling structure that can quickly engage screws.

[Conventional technology]

Conventionally, when a male screw is screwed into an object to be screwed together (a female screw), the male screw is rotated with respect to the object to be screwed together.

[Invention or problem to be solved]

For this reason, there was a problem in that the screwing work took time.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a coupling tool and a coupling structure that allow male screws to be quickly screwed together.

[Means to solve the problem]

The coupling device according to the present invention includes a base, a screw insertion hole provided in the base, and a plurality of plate-shaped plates, each having a tip facing toward the center of the screw insertion hole, and the other end facing the center of the screw insertion hole. It has a threaded piece.

Further, in the coupling structure according to the present invention, a male screw is inserted into a screw insertion hole of the coupling tool, and a tip of a threaded piece of the coupling tool is engaged with a thread groove of the male screw.

[Effect]

In the present invention, when the male screw is pushed into the screw insertion hole of the coupler in the axial direction, the screwing piece is elastically bent and deformed, so that the tip of the screwing piece passes over the thread of the male screw.

Then, at the position where the pushing of the male screw is stopped, the tip of the screwing piece engages with the thread groove of the male screw. As a result, the male screw can be screwed onto the tip of the screwing piece without rotating the male screw relative to the coupling tool.

In addition, if the male screw is not in the desired position when the male screw is stopped being pushed in, if the male screw is rotated, the tip of the screw will be aligned with the male screw. The screwing position can be precisely adjusted to a desired position because it moves relatively along the thread groove.

〔Example〕

Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

Next, the operation of this embodiment will be explained.

As shown in FIG.
It can be attached to the mounting body 6.

Then, as shown in FIGS. 1 and 5, the male thread 7
When pushed into the screw insertion hole 5 in the axial direction, the threaded piece 3 is elastically bent and deformed, so that the tip 3b of the threaded piece 3 passes over the thread of the male screw 7.

Further, when the pushing of the male screw 7 is stopped, the tip 3b of the screwing piece 3 engages with the thread groove of the male screw 7 at that position.

Thereby, the male screw 7 can be screwed into the tip 3b of the screwing piece 3 without rotating the male screw 7 with respect to the coupling tool 1.

In addition, if the screwing position of the male screw 7 with respect to the screwing piece 3 of the coupler 1 is shifted from the desired position when the pushing of the male screw 7 is stopped in this way, if the male screw 7 is rotated, Since the tip 3b of the screwing piece 3 moves relatively along the thread groove of the male screw 7, the screwing position can be precisely adjusted to a desired position.

Figures 6-10 show a second embodiment of the invention.

In this embodiment, as in the case of the first embodiment, the coupling tool 1 is formed by press-forming a metal plate material such as steel, stainless steel, or spring steel, and includes a base 2, a plurality of threaded pieces 3, and a driving portion. 4 are integrally formed. The group 7J

Each of the plurality of threaded pieces 3 has one end 3a (hereinafter referred to as the base end) continuous with the peripheral edge of the screw insertion hole 5 of the base 2, and extends from the peripheral edge toward the center of the screw insertion hole 5. The screws extend radially toward each other, and their tips 3b are directed toward the center of the screw insertion hole 5. Further, each screwing piece 3 has an inclined part 3c and a parallel part 3d, the inclined part 3c is sloped downward from the base end 3a toward the center, and the parallel part 3d is It bends from the inclined portion 3c and extends parallel to the base 2 to the tip 3b.

The driving portion 4 is bent at 90 degrees from the four corners of the base portion 2, and its tip portion is sharpened.

Next, the operation of this embodiment will be explained.

As shown in FIG. 10, this coupling tool 1 can be attached to an object to be attached 6, such as a wall, by driving the driving portion 4 into the object to be attached 6.

The screwing of the male screw 7 into the connector 1 and the adjustment of the screwing position can be performed in the same manner as in the first embodiment.

In addition, in the first embodiment and the second embodiment, when the male screw 7 is not screwed into the connector 1 as shown in the figure, the tips 3b of each screwing piece 3 are arranged on the same plane. If configured, the tip 3b of each screwing piece 3 or the male screw 7
When screwed into the thread groove, each threaded piece 3 is elastically deformed, thereby displacing the tip 3b of each threaded piece 3 to a position corresponding to the spiral of the threaded groove. At this time, the screwing piece 3
Due to the elastic deformation, the male thread 7 tends to be slightly inclined from the vertical direction with respect to the coupling tool 1.

Therefore, if it is desired to avoid such an inclination, the male thread 7 is not screwed into the discussion tool 1,
In other words, when the connector 1 is in a free state, it is preferable that the tips 3b of each screwing piece 3 are not on the same plane, but are already at a position corresponding to the spiral of the thread groove of the male screw 7.
