Detailed Description of the Invention

[Object of the Invention]

[0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a locking material holding groove for locking a locking material such as a nut.

[0003]

2. Description of the Related Art As a conventional locking member holding groove of this type,
For example, the configuration described in Japanese Utility Model Laid-Open No. 1-99811 is known.

The locking member holding groove has a longitudinal opening in the member to be mounted, and an inside of the opening is substantially parallel to the opening through a space for holding the locking member such as a nut. An accommodating portion having a contact surface and capable of accommodating the locking member is provided above the contact surface.

Then, after the locking member is once housed in the housing through the front opening, the locking member is positioned at a predetermined position,
A bolt or the like is screwed onto the locking material and mounted on the mounted member.

[0006]

However, in the above-mentioned locking material holding groove, the locking material is inserted from the opening, and the locking material is brought into contact with the contact surface at a predetermined position and screwed with a bolt or the like. In the case of mating, there is a problem that the locking member floats up toward the accommodation portion, the center is displaced, and it is difficult to screw.

The present invention has been made in view of the above problems, and a normal locking member can be inserted from the front opening, and
An object of the present invention is to provide a locking material holding groove that can be easily attached.

[0009]

DISCLOSURE OF THE INVENTION The locking material retaining groove of the present invention is provided with a longitudinal opening through which the locking material can be inserted, and the locking material which is formed on both sides along the opening. First and second locking edges having first and second locking surfaces on the inner surface side, and inside the first locking edge along the longitudinal direction of the opening. A support surface formed substantially orthogonal to the toe, a contact surface formed on the opposite side of the support surface from the first locking surface and substantially parallel to and facing the locking surface, A rotation blocking surface that is provided inside the second locking surface to face the support surface and blocks rotation of the locking member, and is formed on the opposite side of the rotation blocking surface from the first locking edge. An accommodating portion that communicates with the opening and accommodates the locking member, and an inclined surface that is inclined from the accommodating portion toward the opening and is formed continuously with the locking surface. It is those provided with the.

[0010]

In the present invention, the locking member is inserted through the opening and once
After accommodating the locking material in the storage part, the locking material slides on the inclined surface,
Located on the support surface. When the locking member is mounted by screwing, a force is applied to the locking member from the opening surface direction, the locking member is pressed and abutted against the contact surface, and when the locking member is screwed, the rotation blocking surface is engaged. The locking material is prevented from rotating, and finally,
The locking member is locked to the first and second locking surfaces, the first and second locking edges are held between the locking member and the mounting object, and the mounting object is mounted on the mounting target. Therefore, the locking member can be inserted from the opening on the front surface and easily attached.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a retaining material holding groove of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a member to be mounted, and a front surface 2 of the member 1 to be mounted is formed with an opening 3 through which a nut N, which is a longitudinally long locking member, can be inserted. A first engaging edge 4 and a second engaging edge 5 are formed on both sides below and above the opening 3 so as to project in a plate shape flush with the mounted member 1 on the front surface.

A first locking surface 6 that is substantially parallel to the front surface 2 is formed inside the first locking edge 4, and an inner surface side of the second locking edge 5 is substantially parallel to the front surface 2. The second locking surface 7 is formed. In addition, the first locking surface 6 has a support surface 8 serving as a bottom surface.
Are formed inwardly in a direction perpendicular to the first locking surface 6 along the longitudinal direction of the opening 3, and the width of the support surface 8 is equal to that of the nut N.
It is a little wider. Further, on the second locking edge 5, a ridge portion 11 having a width narrower than the width direction of the support surface 8 is formed inwardly in a direction perpendicular to the second locking surface 7.
The lower surface of the protrusion 11 is parallel to the supporting surface 8 and
The distance between them is formed to be slightly wider than the shortest diameter portion of the nut N, and a taper surface 13 is formed at the inner tip of the rotation blocking surface 12.

A mounting groove 14 is provided in the upper portion of the protrusion 11. Further, a top surface 15 wider than the supporting surface 8 is formed in parallel with the supporting surface 8 at the upper part of the mounting groove 14. A rear surface portion 16 is formed substantially perpendicular to the top surface 15 and parallel to the second locking surface 7. A housing portion 17 for housing the nut N is formed in a portion surrounded by the top surface 15 and the rear surface portion 16.

Further, an inclined surface 18 having a diameter reduced downward is formed continuously from the rear surface portion 16 at the lower portion of the rear surface portion 16,
Further, a contact surface 19 is formed below the inclined surface 18 so as to face the first locking surface 6 in parallel, and is formed continuously from the inclined surface 18.

Next, with reference to FIGS. 2 to 4, the mounting of the plate material A as the mounted object will be described.

First, the nut N is inserted from the front opening 3 as shown in FIG. At this time,
Since the tapered surface 13 is provided at the tip of the protruding portion 11, the nut N can be easily inserted along the tapered surface 13.
In this state, the nut N is lowered along the inclined surface 18 and the lower portion of the nut N is brought into contact with the support surface 8. Then, as shown in FIG. 3, one side of the nut N is placed on the support surface 8,
The rotation blocking surface 12 is located above the other side facing the one side.

Then, as shown in FIG. 4, a bolt B is inserted into a hole (not shown) of the plate material A, the plate material A is inserted between the nut N and the bolt B, and the bolt B is screwed onto the nut N. To combine. At this time, although the nut N is pressed rearward, the nut N is brought into contact with the rear contact surface 19 and positioned, and the center of the nut N is not displaced. Further, since the nut N is sandwiched between the rotation blocking surface 12 and the support surface 8 with a gap, the rotation of the bolt B prevents the nut N from idling. Then, when screwed securely, the first and second locking edges 4 and 5 and the plate material A are sandwiched between the bolt B and the nut N,
Since the nut N is locked by the first and second locking surfaces 6 and 7, the plate material A can be reliably mounted on the mounted member 1.

Although a hexagonal nut is used as the locking member, the present invention is not limited to this, and a quadrilateral nut or other specially shaped nut may be used.

[0020]

According to the locking material holding groove of the present invention, a housing portion for housing the locking material is formed inside the opening through which the locking material can be inserted, and from this housing portion, the inclined surface and the contact surface are formed. Since the surface is formed, a normal locking material holding groove can be inserted from the opening on the front surface, and the locking body is abutted by the abutment surface and sandwiched between the rotation blocking surface and the support surface, so that Since it can prevent deviation and idling, it can be easily installed.
