Description

Description: TECHNICAL FIELD The present invention relates to a pipe bracket applied to attach hydraulic pipes and the like of a vehicle-mounted hydraulic system to a vehicle body member.

(Prior Art) Conventionally, as a piping bracket, for example, one shown in FIG. 7 is known.

This conventional piping bracket b includes a block fixing plate portion 01 to which a piping block PB to be welded to an end portion of the pipe P is fixed, and a bracket fixing plate portion 02 to be fixed to a vehicle body member when the piping is attached to the vehicle body. , Plate parts 01,0
It is configured to include an intermediate plate portion 03 that integrally connects the two.

(Problems to be solved by the invention) However, such a conventional piping bracket b
In this case, the pipe bracket b when installing the pipe on the vehicle body
Since the work can be carried out without temporarily holding the above, there was a problem that the bracket b for piping was blunted for a long time.

That is, when the pipe is attached to the vehicle body, as shown in FIG. 8, first, the pipe system is arranged together with the hydraulic equipment at a predetermined attachment position, and the pipe P is fixed by the brackets b ₁ and b ₂ from a position close to the hydraulic equipment. The procedure is to fix the pipe bracket b at the end of the pipe having the pipe block PB at the end.

Therefore, until the piping bracket b is fixed to the vehicle body member M by bolts, the pipe bracket b is in a cantilevered support state with the previously fixed bracket position as a fulcrum.
Since the piping bracket portion at the tip of the piping system has a high weight due to the fixing of PB, etc., the piping bracket b is shaken for a long time as shown by the arrows in FIGS. 8 and 9.

As a result of the brazing of the piping bracket b for a long time, interference with peripheral members, workers and equipment occurs, and the piping P
The piping block PB and the piping bracket b could be deformed or damaged.

Further, as a solution to this problem, there is a plan to add a claw member for temporary holding to the pipe bracket, but in this case, it causes an increase in weight and an increase in cost.

The present invention has been made in view of the above-mentioned problems, and in a piping bracket to which a piping block is fixed, the bracket can be used for a long time when the piping is attached to a vehicle body without increasing weight and cost. The challenge is to prevent getting stuck.

(Means for Solving the Problem) In order to solve the above problems, in the pipe bracket of the present invention, a block fixing plate portion to which a pipe block to be welded to an end portion of the pipe is fixed, and a pipe fixing time when the pipe is attached to the vehicle body. A bracket fixing plate portion fixed to a vehicle body member, an intermediate plate portion connecting the block fixing plate portion and the bracket fixing plate portion, and a bracket are integrally formed by cutting and raising a part of the bracket. In a fixed state, it can be temporarily held by the vehicle body member, and in a bracket fixed state to the vehicle body member, a cut-and-raised part having a temporary holding claw arranged at a sufficient gap with the vehicle body member is provided. It is a means characterized by

(Working) Taking hydraulic piping as an example, when installing the piping on the vehicle body, first place the piping system together with the hydraulic equipment at the specified mounting position, and then use the temporary holding claws on the cut-and-raised portion of the piping bracket. Temporarily holds the vehicle body member.

Then, fix the piping to the piping block of the bracket sequentially from the position close to the hydraulic equipment at the predetermined position, and finally remove the temporary holding of the piping bracket and attach bolts etc. to the bracket fixing plate of the piping bracket. It is carried out by the procedure of fixing using.

Therefore, the brazing of the pipe bracket for a long time as in the past is prevented, and as a result, interference with peripheral members, workers, and equipment occurs, and the pipes, pipe blocks, and pipe brackets may be deformed or damaged. Nor.

Further, since the cut-and-raised portion as the temporary holding member is an internal addition member formed integrally with the bracket, when the temporary holding member is formed by external addition as a separate body or in order to obtain a temporary holding function, it is integrated. Compared to the case where the temporary holding portion is formed by extending from one end of the bracket to the outside, the weight and cost are not increased.

Further, since the temporary holding claw of the cut-and-raised portion is arranged with a sufficient gap with the vehicle body member when the pipe is attached, the cut-and-raised portion is used for purposes other than the temporary holding such as fixing the connector of the harness. be able to.

(Example) Hereinafter, the Example of this invention is described based on drawing.

 First, the configuration will be described.

FIG. 1 shows a pipe bracket B of an embodiment applied to attach a hydraulic pipe of a vehicle-mounted hydraulic system (for example, a rear wheel steering system or a brake system) to a vehicle body member M.

The piping bracket B includes a block fixing plate portion 1, a bracket fixing plate portion 2, an intermediate inclined plate portion 3 (intermediate plate portion), and a cut-and-raised portion 4.

A pipe block PB to be welded to an end portion of the pipe P is welded and fixed to the block fixing plate portion 1 at an intermediate position of the end portion thereof.

The bracket fixing plate portion 2 is provided with two bolt holes 2a which are fixed to the vehicle body member M by bolts V when the pipe is attached to the vehicle body.

The intermediate inclined plate portion 3 connects the block fixing plate portion 1 and the bracket fixing plate portion 2 which are substantially parallel and separated from each other in an inclined state of about 45 °.

The cut-and-raised portion 4 is formed by cutting and raising a part of the intermediate inclined plate portion 3 and a portion of the bracket fixing plate portion 2, and as a result of the cut-and-raised portion, the tip end portion has a vehicle body. Temporary holding claws 4a (bracket fixing plate 2
Corresponding to the cut-and-raised part) is formed.

 Next, the operation will be described.

(B) When manufacturing the bracket for piping When the cut-and-raised portion 4 is formed during manufacturing of the bracket for piping B, as shown in FIG. 2, a part of the intermediate inclined plate portion 3 and the bracket fixing plate portion 2 are formed. This is done by making a U-shaped cut in a part of the area, and then raising the part surrounded by this cut as shown by the arrow in FIG.

Incidentally, like a piping bracket of FIG. 3 corresponding to another embodiment of the present invention, a cut-and-raised part having a U-shaped cut in only the bracket fixing plate part 2 and having a temporary holding claw at the tip part. In the case of forming a groove, it is necessary to perform two steps of a cutting and raising step and a bending step.

Therefore, in the embodiment, the intermediate plate portion is inclined, and a U-shaped cut is formed in a part of the intermediate inclined plate part 3 and a part of the bracket fixing plate part 2. Compared to the case, the cut-and-raised part 4 having the temporary holding claw 4a at the tip can be formed by one cut-and-raised process without the bending process.

(B) At the time of attaching the pipe P to the vehicle body When attaching the pipe P to the vehicle body, first arrange the pipe system together with the hydraulic equipment at a predetermined attaching position, and then, as shown in Fig. 4, cut and raise the pipe bracket B. The bending portion 4 temporarily holds the vehicle body member M. Then, the pipe P is fixed to a predetermined position with a bracket from a position close to the hydraulic equipment, and finally, the temporary holding of the pipe bracket B is removed, and the pipe bracket B is fixed with a bolt V.

Therefore, the brazing of the piping bracket for a long time as in the past is prevented, and as a result, interference with peripheral members, workers and equipment occurs, and the piping P, the piping block PB and the piping bracket B are deformed or damaged. It never reaches.

(C) When installing the harness When the harness H is installed along the vehicle body member M after the installation of the pipe P on the vehicle body is completed, as shown in FIGS. The connector C of the harness H can be fixed to the temporary holding claw 4a of the cut-and-raised part 4 arranged via the.

Therefore, the cut-and-raised portion 4 is not removed even after the piping is attached to the vehicle body.
Can be effectively used as a fixing member for the connector C of the harness H.

As described above, the piping bracket B of the embodiment has the features listed below.

Since the pipe bracket B has a function of temporarily holding the vehicle body member M by the cut-and-raised portion 4, it is possible to prevent the pipe bracket B from sticking to the pipe body for a long time when the pipe is attached to the vehicle body.

Since the cut-and-raised portion 4 as the temporary holding member is an internal addition member integrally formed with the bracket, it does not cause an increase in weight or cost as compared with the case of a member formed by external addition.

After the pipe is attached, the temporary holding claws 4a of the cut-and-raised portion 4 are arranged with a sufficient gap with the vehicle body member M, so that the cut-and-raised portion 4 is not temporarily held, for example, by fixing the connector C of the harness H. It can be used for various purposes.

Since the cut-and-raised part 4 having the temporary holding claw 4a is formed in one cut-and-raised process, the cut-and-raised part 4 having the temporary holding claw 4a is formed.
The cut-and-raised portion 4 can be formed at a lower cost than in the case where the cut-and-raised process and the bending process are required for forming.

The preferred embodiment has been described above with reference to the drawings. However, the specific configuration is not limited to this embodiment, and design changes and the like within the scope not departing from the gist of the present invention, for example, referring to FIG. Even such brackets are included in the present invention.

(Effects of the Invention) As described above, in the piping bracket of the present invention, the bracket can be temporarily held by the vehicle body member when the bracket is not fixed to the vehicle body member, and the bracket is fixed when the bracket is fixed to the vehicle body member. Since the cut-and-raised part having the temporary holding claw disposed at a sufficient gap with the vehicle body member at the tip is integrally formed by cutting and raising a part of the bracket,
The effects listed below are also obtained.

Since the pipe bracket has a function of temporarily holding the vehicle body member by the cut-and-raised portion having the temporary holding claw, it is possible to prevent the pipe bracket from sticking for a long time when the pipe is attached to the vehicle body.

As the temporary holding member, the cut-and-raised portion is an internal addition member formed integrally with the bracket, so that it does not cause an increase in weight or cost as compared with the case where the cut-raised portion is formed as a separate member or an external member added integrally.

After the pipe is attached, the temporary holding claw of the cut-and-raised part is arranged with a sufficient gap with the vehicle body member, so that the cut-and-raised part can be used for purposes other than the temporary holding, such as fixing the connector of the harness.
