Description

[0001]
[Industrial application fields]
The present invention relates to a pipe support, and more particularly to a pipe support for attaching pipes such as a fuel pipe and a brake tube to an automobile body.
[0002]
[Prior art]
Conventionally, a pipe support provided with a pipe retaining piece facing the pipe insertion port, provided with a pipe receiving seat at the bottom of the insertion port, and provided with an insertion portion for a stud bolt provided on an attachment object on the main body thereof. It was known. (For example, see Japanese Patent Publication No. 5-85796)
[0003]
[Problems to be solved by the invention]
However, it has not been easy to visually confirm that the conventional pipe support is sufficiently and accurately attached to an attachment object (hereinafter referred to as a body) via a stud bolt.
If the connection between the body and the pipe support is not sufficient, the pipe holder may be rattled by a gap formed between them.
[0004]
[Means for Solving the Problems]
The present invention aims to solve the above-mentioned problems. The gist of the present invention is that a plurality of pipe holding portions are provided on the pipe support body, and the object to be attached is provided between the pipe holding portions. An insertion part to the stud bolt is provided, each pipe holding part is provided with a pipe insertion opening and a pipe retaining piece facing the pipe insertion opening, and a pipe receiving seat is provided at the bottom of the pipe insertion opening. In the pipe support provided with an insertion port for the stud bolt and a retaining piece extending downward provided on one or both sides of the inner wall of the insertion port in the part, the bottom of the insertion port, from the inner wall of the bottom wall to the center of the bottom There is provided a pipe support characterized in that a movable piece extending in the direction is provided, and an elastic member attached to the peripheral upper surface of the insertion port and extending laterally from the upper surface is provided.
[0005]
[Action]
In the present invention, when the pipe support is attached to the stud bolt, the movable piece provided at the bottom of the bolt insertion port of the insertion portion is pushed outward by the lower end of the stud bolt to be inserted. It is visually confirmed that the support is correctly attached to the object to be attached.
Moreover, the elastic member provided adjacent to the insertion port of the stud bolt fills the gap between the attachment object and the pipe support by its elasticity, and prevents the pipe support from rattling.
[0006]
【Example】
FIG. 1 shows an attachment object (hereinafter referred to as a body) 1, for example, an inner wall of an engine room and a stud bolt 2 fixed thereto.
2 to 6 show the pipe support of the present invention, which is formed of a hard elastic body such as an elastic hard synthetic resin. In each figure, 11 is a pipe support main body, and 12 is a pipe holding portion provided side by side on the main body 11. The figure shows six pipe holders.
[0007]
Each holding portion includes a pipe insertion opening 13, a pipe retaining piece 14 extending downward from one or both sides thereof, and a pipe receiving seat 15 provided at the bottom of the insertion opening.
The length or shape of the pipe retaining piece 14 and the size of the receiving seat 15 are determined by the thickness of the pipe to be received.
[0008]
As shown in FIG. 2, the leftmost holding portion is for a large diameter pipe, and the rightmost holding portion is for a small diameter pipe. Further, the pipe retaining pieces 14 may be provided on both sides of the pipe insertion opening 13 as seen in the third holding portion from the left side, and formed by a pair of elastic pieces 16 that open the receiving seat 15 upward. May be. Reference numeral 17 denotes a rising portion that forms a holding portion together with a pipe retaining piece and a receiving seat. Conventionally, the above structure is well known in this type of pipe support, and the number of holding parts, the shape and structure of retaining pieces and receiving seats can be arbitrarily designed according to the arrangement of the pipes to be held. It can be.
[0009]
In FIGS. 2-6, 3 is fitted portion. In the insertion portion 3, 18 is an insertion port for the stud bolt 2, and retaining pieces 20, 20 extend downward from the rising portions 19, 19 on both sides of the insertion port in two steps.
Each retaining piece 20 has a recess 21 at its tip, and has a crab claw shape in the front view. A through hole 22 is provided at the bottom of the insertion port 18, and a movable piece 23 extends from the main body 11 on both sides thereof toward the center. The movable pieces 23 and 23 have their tip portions balanced with each other, or are connected in advance by a connecting film thinner than the movable pieces 23 and 23 .
A raised portion 24 is formed at the tip of the illustrated movable piece 23.
Elastic members 25, 25 extending in opposite directions from the center of the upper surface of the rising parts 19, 19 are formed in the width direction of the main body 11 at the upper part of the insertion opening 18. This elastic member has a strip shape in the illustrated embodiment.
[0010]
The present embodiment is configured as described above and is used as follows.
First, the pipe shown in FIG. 1 is inserted into the holding part 12 at the left end of FIG. 2 as shown by the phantom line, and then the pipe shown in FIG. The pipe support is moved upward toward the bolt 2, and the stud bolt 2 is inserted into the insertion port 18.
[0011]
Then, each retaining piece 20 is pushed open by the stud bolt, and when the pipe support is attached to the body 1 sufficiently and accurately, the lower end of the stud bolt 2 pushes the movable piece 23 downward, The state shown in FIG. This makes it very easy to see from the outside.
At this time, each of the retaining pieces 20 is prevented from slipping out of the insertion port 18 because the tip of the retaining piece 20 is not easily inserted into the threaded groove of the stud bolt. The recess 21 serves to engage the stud bolt 2.
The raised portion 24 of the movable piece 23 helps to push and open the movable piece 23 by the stud bolt, and helps to visually confirm that the pipe support is attached to the body 1 sufficiently and accurately.
[0012]
At that time, as shown in FIG. 5, the elastic members 25 and 25 are bent at the opposite ends thereof by the body 1 to bend downward, and the pipe support is always elastically coupled to the body 1, Prevents play between the two.
[0013]
【The invention's effect】
According to the present invention, the pipe support can be attached to the stud bolt of the body with a single touch, and whether or not the pipe support is attached sufficiently and accurately is provided on the lower surface of the main body. The protrusion of the piece allows easy visual recognition, and of course, it can be confirmed by touching with a hand.
In particular, when the pipe support is attached to the body by upward work in the assembly process, the efficiency can be significantly improved.
In addition, since the pipe support is attached to the stud bolt by the retaining piece and its elasticity, even if the diameter or shape of the stud bolt is changed, it can be adapted to exhibit a reliable support action.
Furthermore, since the elastic member is disposed adjacent to the stud bolt insertion port of the pipe support, the connection of the pipe support to the body is not loosened, and play between the two can be eliminated.
