CONSTITUTION:An insert comprises a main body 1, a driver groove 2 for enabling the main body 1 to be mounted by a driver, an outer circumferential tap 3 for biting in a resin part 7, an inner circumferential tap 4 for mounting a screw, and an-inner circumferential no-tap part 5 for shortening the time for fixing the screw. The driver is set in contact with the driver groove 2, the insert is turned, and the insert is mounted on the resin parts 7 or demounted from the resin part 7.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insert, and more particularly to an insert incorporated in a structural component for use.

[0002]

2. Description of the Related Art A conventional insert will be described with reference to the drawings.

FIG. 6 is a sectional view of a conventional insert.

The conventional insert has a main body 1 and an inner peripheral tap 4.

Usually, when inserting the insert into the resin component 7, ultrasonic vibration is applied by dedicated equipment.

Further, in order to take out the insert inserted in the resin component 7, the resin component 7 is broken and taken out.

When tightening the screw, the internal tap 4 is spread over the entire hole, so that the screw is tightened to the end.

[0008]

DISCLOSURE OF INVENTION Problems to be Solved by the Invention In the above-mentioned conventional insert, in order to take out the insert inserted in the resin part, it is necessary to break the resin part and take it out. However, there is a problem that the resin and the metal are mixed with each other when it is carried out, so that it is difficult to separate and discard them.

The conventional insert has a problem that it takes a long time to attach and detach the screw because all the tapped holes are cut in the insert.

Since the conventional insert requires special equipment when inserting the insert into the resin part, it can be done only by the resin molding maker, and the unit price of the part purchased from the maker increases, and the insert is inserted. The problem is that it takes time.

[0011]

The insert of the present invention comprises:
It is characterized in that it is provided with an outer peripheral tap for attaching to or detaching from a component and a groove for a driver for attaching and detaching.

The insert of the present invention is characterized by having an inner peripheral tapped portion with taps in the screw holes for the screws to be inserted and an inner peripheral non-tapped portion without taps.

[0013]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a perspective view of an embodiment of an insert according to the present invention.

The insert of this embodiment has a main body 1 of the insert, a driver groove 2 for mounting with a driver, and an outer peripheral tap 3 for biting into the resin component 7.
And an inner circumference tap 4 for attaching the screw 8 to the main body 1.
And there is no inner circumference tap to shorten the time for fixing screws. 5
Composed of and.

Next, the attachment and detachment operations of the insert of this embodiment will be described with reference to the drawings.

FIG. 2 is a sectional view of an embodiment of the insert according to the present invention.

1 and 2, the hole 10 in the body 1
The screw 8 is inserted in the. The hole 10 is composed of an inner peripheral tap 4 for fixing the screw 8 and an inner peripheral tapless portion 5.

The inner peripheral tapless portion 5 is located on the side of the driver groove 2 on the side where the screw 8 is inserted, and the inner peripheral tap 4 extends from the end of the inner peripheral tapless portion 5 to the driver groove 2.
Continue to face-to-face.

On the side where the screw 8 is inserted, there is no inner peripheral tapped portion 5.
Therefore, only the tip portion of the screw 8 meshes with the inner peripheral tap 4.

FIG. 3 is a sectional view showing an example in which the insert of FIG. 2 is attached to a resin component.

The mounting direction of the insert of this embodiment is on the outer periphery of the main body 1 by placing the driver 6 in which the facing surface of the driver groove 2 faces the resin component 7 in the driver groove 2 and turning in the inserting direction. Peripheral tap 3 is resin part 7
It digs into and is attached to the resin component 7.

On the contrary, if the driver 6 is turned, the driver of this embodiment can be removed from the resin component 7 and removed. With these, the driver 6 can be inserted even in a place where the equipment required for the insert insertion work is not normally provided.
Even if the screw thread of the inner peripheral tap 4 is broken, the resin part 7 can be reused by removing the resin part 7 without breaking it using the driver 6 and attaching another one of this embodiment.

When the resin component 7 is discarded, the driver 6 is used to remove the resin component 7 from the resin component 7 without breaking it, and the resin component 7 is separated and discarded.

Further, since the insert of this embodiment is attached by the driver 6, the resin component 7 is manufactured by the molding maker.
It does not need to be attached to.

FIG. 4 is a sectional view showing an example in which another component is attached to the resin component to which the insert of FIG. 3 is attached.

When the component 9 is fixed to the resin component 7 in which the insert is inserted as shown in FIG. 3, the component 9 is attached to the insert of the resin component 7 with the screw 8 by the screwdriver 6.

FIG. 5 is a sectional view showing an example in which the insert of FIG. 2 is attached to a resin part and other parts.

Due to the assembly procedure, the resin parts 7, 9,
When the components 11 cannot be fixed at the same time, the resin component 7 and the component 11 are first fixed by the insert of this embodiment, and the component 9 is fixed to the resin component 7 by using the screw 8.

[0030]

As described above, the insert of the present invention is provided with the outer peripheral tap, the inner peripheral tapless portion, and the driver groove, so that the following effects can be obtained. (1) When inserting the insert into the resin component, it can be attached and removed with a screwdriver, so sorting and disposal can be done easily.

Further, since no dedicated equipment is required, insert mounting is possible even if not a resin molding maker.
It becomes a factor of cost reduction of resin parts. (2) Since there is no tap on the inner circumference, it is possible to shorten the time when installing the screws.
