Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a clip with a nut for fixing pipes, wire harnesses, etc. to the body of an automobile.

(Prior Art) Conventionally, resin clips have often been used to fix pipes, wire harnesses, etc. to bodies. Various types of this clip have been developed, and in particular, there are several types of methods for fixing it to the body side. For example, there are widely known types that are fitted using holes drilled in the body, and types that use stud bolts that protrude from the body.

(Problems to be Solved by the Invention) Among the above, in the case of the type using stud bolts, the clip must be screwed or hammered into it. You have to work while doing so. Therefore, since the work is cumbersome and time-consuming, it cannot be said to be an appropriate type for assembly lines where speed is required.

Therefore, the present invention provides a clip that can be temporarily fastened to a stud bolt in order to eliminate the need for screwing or hammering, thereby contributing to improving work efficiency on the line. The aim was to

(Means for Solving the Problems) In order to achieve this object, the clip is constructed in the following manner in the present invention. That is, a base is provided with a cylindrical insertion hole penetrating in the vertical direction, a holding hole connected to both left and right ends of this base for storing a pipe, etc., and protruding into this holding hole,
A clip member integrally molded from a synthetic resin, comprising at least one pipe holding part equipped with a clamp claw that elastically engages and holds a pipe, etc.; a prismatic nut part having a substantially hexagonal cross section; and a cylindrical nut part. The clip member is provided with a hollow insertion tube and a brim-like pressing flange, and is loosely inserted into the insertion hole of the clip member and screwed onto a stud bolt protruding from the body of an automobile, etc., to attach the clip member to the body, etc. and a nut member to be fixed, and these two members are usually combined together by a connecting means, and either the inner circumferential surface of the insertion hole of the clip member or the inner circumferential surface of the insertion cylindrical portion of the nut member A temporary fixing pawl that can be engaged with the stud bolt is protruded inward from one side, and a wall for biting is provided that protrudes from the inner circumferential surface of the insertion cylindrical portion of the nut member, so that the nut member can be rotated or This is a clip with a nut, in which the wall body is screwed onto the stud bolt and the pressing flange presses the clip member when it is pushed in.

(Function) Therefore, according to the above structure, when the nut member is inserted into the stud bolt through the through hole while the pipe, etc. is held by the clip member, the temporary fixing pawl engages with the stud bolt. For,
The entire clip is temporarily attached to the body or the like. After this, when the nut member is hammered in or screwed in, the nut member presses the clip with its pressing portion and bites into the stud bolt, thereby fixing the entire clip to the body or the like.

(Example) Hereinafter, an example embodying the present invention will be described in detail with reference to the drawings.

1 to 6 show a clip c1 according to a first embodiment of the present invention. The clip c1 of this example consists of a clip member 1 and a nut member 2, each of which is made of a synthetic resin material. First, the clip member 1 will be explained.

The clip member 1 has a nut member 2 at its center.
A base 3 for holding a pipe is integrally provided, and two pipe holding parts 4a and 4b of different sizes are symmetrically arranged at both left and right ends of the base 3, each having a different size. It is set in. Each pipe holding part 4a, 4b consists of a holding hole 5 for storing a pipe or the like P, and a clamp claw 6 for elastically engaging the pipe or the like P into the holding hole 5 and holding it.

On the other hand, a peripheral wall 7 of a predetermined height is erected on the periphery of the upper surface of the clip member 1. Of this peripheral wall 7, only the portion corresponding to the base 3 is projected in an arc shape, so as to avoid interference with a pressing flange 8 of a nut member 2, which will be described later. Furthermore, an insertion hole 9 for the nut member 2 is formed in the clip member 1 passing through the center portion of the base portion 3. And this insertion hole 9
A locking step edge 10 is formed along the circumferential direction near the opening end on the lower surface side.

Next, the nut member 2 will be explained. The nut member 2 has a hexagonal nut portion 11 formed on one side with the pressing flange 8 as a boundary, and an insertion cylinder portion 12 is integrally formed on the other side.
A through hole 13 for a stud bolt B is coaxially formed in the nut member 2. A pair of biting walls 14 for biting into the stud bolt B are integrally attached to the inner wall surface of the upper side (the side of the nut portion 11) of the through hole 13. Further, a pair of retaining pawls 15 are respectively protruded from the open end of the outer wall of the insertion cylindrical portion 12 at positions corresponding to the above-mentioned biting walls 14, and engage with the locking step edge 10. be able to. The locking step edge 10 and the retaining pawl 15 constitute a connecting means for assembling the clip member 1 and the nut member 2 together. Further, on the outer wall of the insertion cylinder portion 12, both of the retaining claws 1
Elastically deformable temporary fixing pawls 17 are formed by making cuts 16 along the axial direction at positions orthogonal to 5. Both temporary fixing claws 17 each have a hook edge 18 facing inward at the lower end.
It is designed to engage stud bolt B.

Note that the above-mentioned notch 16 allows the distal end side of the insertion tube portion 12 to be slightly elastically deformed in the compression direction.

Next, an example of the installation work of the pipe etc. P will be explained.
First, the insertion cylindrical portion 12 of the nut member 2 is fitted into the insertion hole 9 of the clip member 1. Then, while the pressing flange 8 comes into contact with the upper surface of the base 3,
The retaining pawl 15 elastically engages with the locking step edge 10. In this way, the nut member 2 and the clip member 1 are coupled together as shown in FIG.

In this state, a pipe or the like P is attached to each pipe holding portion 4a, 4b of the clip member 1. This installation work involves attaching the pipes P to each pipe holding section 4a, 4b.
This is done by placing the clamp on the lower side of the clamp claw 6, and then pushing the clamp claw 6 apart to fit it into the holding hole 5.

After this, the entire clip c1 is fixed to the body, but before the fixing work, the clip c1 is
Perform temporary fixing work. In this case, the stud bolt B is lightly inserted into the lower opening of the through hole 13 of the nut member 2. Then, nut member 2
While elastically deforming, both temporary fixing pawls 17 go over the threads of the stud bolt B, and the nut member 2
When the clip c1 is inserted to an appropriate depth, the temporary fixing pawl 17 engages with the thread of the stud bolt B, as shown in FIG. 5, so that the clip c1 is temporarily attached. Therefore, screwing work can be performed on the assembly line even if the worker does not hold the clip c1. That is, by rotating the nut portion 11 with a suitable jig, the nut member 2 and the clip member 1 are gradually screwed into the stud bolt B. As this screwing progresses, the stud bolt B bites into both biting walls 14, so if the clip c1 is screwed in until it comes into contact with the body 19, the clip c1 will cut into the body 19.
Since it is fixed to the body 19 without rattling, the pipe etc. P is securely fixed to the body 19.

Furthermore, if it becomes necessary to remove the clip c1, simply screw back the nut member 2 and the clip c1 can be removed.
1 can be easily removed in the reverse order to the above, so that pipes, etc. can be easily replaced.

7 to 10 show a second embodiment of the present invention. In the second embodiment, the retaining claw 15 in the first embodiment is replaced with the peripheral wall 7 of the clip member 1.
At the same time, temporary fixing claws 17 are formed opposite to the lower opening end of the insertion hole 9 of the clip member 1 and protrude obliquely upward. On the other hand, the nut member 2 has a tapered surface 20 formed on the inner peripheral edge of the lower opening end of the through hole 13 in order to avoid interference with both of the temporary fixing claws 17. Further, in the nut member 2 of this example, the biting wall body 14 is formed over the entire circumference. Note that the other configurations are almost the same as in the first embodiment.

In the second embodiment, the retaining pawl 15 and the pressing flange 8 engaged therewith constitute a connecting means for assembling the clip member 1 and the nut member 2 together.

Clip c of the second embodiment formed in this way
2, the nut member 2 and the clip member 1 can be temporarily fixed to the stud bolt B using the temporary fixing pawl 17 of the clip member 1 in a state where they are combined. Therefore, when the nut member 2 is rotated so as to bite into the biting wall 14, the clip c2 is fixed to the body 19 as in the first embodiment.

11 and 12 show a clip c3 according to a third embodiment of the present invention.

In the third embodiment, the nut member 2 and the clip member 1 are connected by a releasable connecting piece 21. In this example, the connecting piece 21 constitutes a connecting means for assembling the clip member 1 and the nut member 2 together. Specifically, the nut member 2
The lower end of the clip member 1 and the inner edge of the insertion hole 9 of the clip member 1 are connected by a connecting piece 21.
1 can be separated by rotating or hammering the nut member 2.

In addition to the third embodiment, the nut and clip members 1 and 2 can be connected in the 13th embodiment.
Clip c of the fourth embodiment shown in Figures and Figure 14
4 may be used. That is, in the fourth embodiment, the peripheral wall 7 of the clip member 1 is formed to be high and elastically deformable, and the clamping pieces 22 for sandwiching the pressing flange 8 of the nut member 2 are provided on the upper part of the peripheral wall 7 to face each other. In this example, the clamping piece 22 and the pressing flange 8 constitute a connecting means for assembling the clip member 1 and the nut member 2 together.
