Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mounting structure for a piping clamp.

[0002]

[Prior Art]

 On the underside of the vehicle floor panel, there are various pipes such as a fuel pipe and a return pipe that connect between the engine in the front of the vehicle and a fuel tank in the rear of the vehicle, and a hydraulic pipe for braking that connects the brake valve in the front of the vehicle and the rear wheel brake body. Pipes are piped. These pipes are supported, for example, as disclosed in Japanese Utility Model Laid-Open No. 55-36798, via a pipe clamp fixed to the lower surface of the floor panel by screws or the like. The pipe clamp is formed of an elastic material such as resin, and is roughly configured by including a clamp member that can elastically clamp and hold each pipe, and a fixing member that fixes the clamp member to the lower surface of the floor panel. ing. The clamp member is formed with a pipe holding portion having a plurality of concave grooves having an approximately Ω-shaped cross section. After holding a predetermined pipe in the pipe holding portion, a fixing member is used to fix the floor panel. It cannot be removed from the bottom surface.

In the piping clamp described in the above publication, an engaging protrusion is formed on the clamp member so that the pipe can be installed after the piping clamp is supported on the floor panel. The clamp member can be temporarily fixed to the floor panel by engaging the fitting protrusion with an engagement hole formed in the floor panel.

[Problems to be solved by the device]

 By the way, the above-mentioned piping clamp provided on the lower surface of the floor panel must be able to reliably hold the pipe held therein and have good workability in its mounting. However, in the pipe clamp mounting structure described in the above publication, the one engaging projection is configured to engage with the engaging hole formed in the floor panel to temporarily fix it. It is not possible to define the rotational position of the clamp member around the engagement protrusion. Therefore, when the pipe is held by the clamp member, the rotation position of the clamp member must be adjusted. Therefore, it cannot be said that the pipe work can be performed well.

Moreover, the clamp member causes the tip end portion of the engaging projection to expand inside the floor panel by screwing a tapping screw into the center hole of the engaging projection that is engaged with the floor panel. The structure is fixed to the floor panel. Therefore, it is attached to the floor panel only by the engaging projections, and the attachment strength is not sufficient. As a result, when the tapping screw is loosened due to vibration or the like, the engaging projection may be disengaged from the engaging hole, and the clamp member may drop off.

Further, in the invention described in the above publication, after the pipe is piped to the clamp member, the fixing member must be attached from below from the tapping screw so as to overlap the pipe holding portion. .. As a result, the number of parts increases, and this fixing member may be lost during piping work.

The present invention has been devised under the circumstances described above, and it is possible to solve the above-mentioned conventional problems and reliably position and hold the clamp member with respect to the floor panel. An object of the present invention is to provide a mounting structure for a piping clamp that can improve the workability of piping, has high mounting strength, and can reduce the number of parts and the number of assembly steps. ..

[0008]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention takes the following technical means. That is, according to the present invention, a clamp member having a pipe holding portion on one side capable of elastically sandwiching a plurality of pipes arranged substantially in parallel is provided to a vehicle body via a clamp band provided so as to surround the outer periphery of the clamp member. A mounting structure for a pipe clamp to be mounted on, wherein at least one engaging protrusion and at least one detent protrusion formed at a predetermined distance from the engaging protrusion are formed on the other side of the clamp member. On the other hand, the clamp band is formed with a through hole through which the engaging projection and the anti-rotation projection are respectively inserted, and the engaging projection and the anti-rotation projection inserted through the through hole of the clamp band The clamp member and clamp band cannot be rotated with respect to the vehicle body by engaging the engaging hole and the rotation stop hole provided in the body, respectively. It is characterized in that both ends of the clamp band surrounding the clamp member are screwed to the vehicle body.

[0009]

[Operation and effect of the device]

 In the present invention, at least one engaging projection and at least one anti-rotation projection are formed on the joint surface of the clamp member to the floor panel, and the engaging projection and anti-rotation projection are formed on the clamp band. After they are inserted through the respective insertion holes, they are engaged with the engagement hole and the rotation stop hole formed in the vehicle body. That is, the clamp band according to the present invention can be attached to the vehicle body integrally with the clamp member, so that the attaching process and the number of parts can be reduced.

Further, since pipe piping can be performed after the clamp member and the clamp band are integrally attached to the vehicle body, the workability of the piping work is good. Moreover, unlike the conventional fixing member, the clamp band according to the present invention cannot be attached separately from the clamp member, so that there is no fear of losing the clamp band during piping work.

In addition, in the clamp mounting structure according to the present invention, the clamp member and the clamp are clamped by engaging the engaging protrusion with the engaging hole and engaging the detent protrusion with the detent hole. The band can be fixed to the vehicle body such that it cannot rotate relative to the vehicle body. Therefore, it is possible to position the clamp member reliably, and it is possible to perform the piping work as it is without adjusting the rotation position of the clamp member. Can be significantly improved.

Further, after holding the pipe by the clamp member, both ends of the clamp band are screwed to the vehicle body so that the clamp band is attached to the pipe holding portion. That is, the clamp member is finally fixed by directly screw-connecting the clamp band provided so as to surround the outer periphery of the clamp member to the vehicle body. Therefore, the mounting strength is much higher than that of the conventional mounting structure in which the tapping screw is screwed into the center hole of the engaging protrusion that is engaged with the vehicle body, and the mounting can be performed reliably. .. As a result, it is possible to form a mounting structure for a piping clamp that is extremely strong against vibrations and shocks.

[Explanation of Examples]

 An embodiment of the present invention will be specifically described below with reference to FIGS. 1 and 2. As shown in FIG. 1, the pipe clamp mounting structure according to the present embodiment has a structure in which a clamp member 2 capable of holding a plurality of pipes 1 arranged substantially in parallel is surrounded by an outer periphery of the clamp member 2. It is generally constructed by fixing it to the lower surface of a floor panel 4 of a vehicle body via a clamp band 3 provided as a member.

The clamp member 2 is formed of an elastically deformable material such as resin, and as shown in FIGS. 1 and 2, has an elongated rectangular parallelepiped shape as a whole. On one side (lower side) of the clamp member 2, there is provided a pipe holding portion 6 in which a plurality of concave grooves 5 having a substantially Ω-shaped cross section are formed in parallel. The groove 5 is formed so as to correspond to the outer diameter of the pipe 1 to be held therein, and by pushing the pipe 1 into the groove 5, the partition walls 7 on both sides thereof are forcibly expanded. Then, the pipe 1 is fitted in the groove 5, and is elastically held by the partition walls 7 on both sides. The number, shape, etc. of the recessed grooves 5 of the pipe holding portion 6 can be changed depending on the number, shape, etc. of the pipes to be held.

On the side (upper surface) of the clamp member 2 opposite to the portion where the pipe holding portion 6 is formed, one engaging protrusion 8 and one turning protrusion formed at a predetermined distance from the engaging protrusion 8. The stop projection 9 is formed integrally with the projection. The engaging projection 8 has an engaging head portion 10 provided with a split groove at its tip end so as to be elastically contracted, and is forcibly elastically fitted into an engaging hole 11 of a floor panel 4 which will be described later. The clamp member 2 is formed so as to be held by the floor panel 4. On the other hand, the anti-rotation protrusion 9 is formed in a substantially cylindrical shape.

The clamp band 3 according to the present embodiment is formed by bending a long plate-shaped member in accordance with the outer peripheral shape of the clamp member 2, and as shown in FIG. While having a substantially V shape in the state, when both ends are overlapped with the lower surface of the floor panel 4 on one side of the clamp member 2, the clamp band 3 surrounds the outer periphery of the clamp member as shown in FIG. Is configured. The V-shaped one side portion of the clamp band 3 which is located between the clamp member 2 and the floor panel 4 has a through hole corresponding to the engaging protrusion 8 and the rotation preventing protrusion 9 of the clamp member 2. The insertion holes 12 and 13 are formed. Further, mounting holes 15a and 15b for screw-connecting the clamp band 3 to the vehicle body are formed at both ends 14a and 14b of the clamp band 3 which are overlapped with the floor panel 4.

In the clamp member 2 and the clamp band 3 having the above structure, as shown in FIG. 2, first, the engaging protrusion 8 and the rotation preventing protrusion 9 are passed through the through holes 12 and 13 of the clamp band 3, respectively. After inserting the clamp member 2 and the clamp band 3 into one body, the engaging protrusions 8 and the anti-rotation protrusions 9 are inserted into the engaging holes 11 and the anti-rotation holes 16 provided in the floor panel 4. Be done. Since the engagement head 10 is formed on the engagement protrusion 8, the clamp member 2 and the clamp band 3 are provided with the engagement hole 11 and the rotation stopper of the engagement protrusion 8 and the rotation stop protrusion 9. By being inserted into the hole 16, it is fixed to the floor panel 4 such that it cannot rotate relative to the floor panel 4.

In this state, as shown in FIG. 2, both ends 14a and 14b of the clamp band 3 are in an open state, and the pipe 1 holds the pipe 1 through the opening. The pipe can be easily carried out by holding the pipe 6 in place. After the piping of the pipe is completed, the clamp band 3 is overlapped with the pipe holding portion 6 so that both end portions 14a and 14b thereof are overlapped with each other, and the attachment bolts 17 are inserted into the attachment holes 15a and 15b. .. The clamp band 3 is connected to the floor panel 4 by screwing the mounting bolt 17 into a weld nut 18 provided on the inner surface of the mounting hole 4a of the floor panel 4. This completes the installation of the pipe pipe and the pipe clamp.

In the pipe clamp mounting structure having the above configuration, the clamp member 2 and the clamp band 3 can be integrally engaged with and fixed to the floor panel 4, so that the number of parts and The number of assembly steps can be reduced. Moreover, since the clamp band 3 is attached to the clamp member 2 at the time of performing the piping work, there is no fear that it will be lost during the piping work.

Further, the clamp member 2 is fixed to the floor panel 4 so as not to be rotatable relative to the floor panel 4 by the engagement protrusion 8 and the detent protrusion 9 formed at a predetermined distance from the engagement protrusion 8. Therefore, the clamp member 2 can be engaged with the floor panel 4 in a reliable posture for pipe piping. As a result, it is possible to significantly improve workability when performing piping work. Further, the clamp member 2 is finally fixed by screwing both ends of the clamp band 3 directly to the front panel 4. Therefore, the mounting strength is extremely high, and even if the engaging projection 8 is disengaged, there is no possibility that the clamp member 2 will fall off.

The scope of the present invention is not limited to the above embodiments. Although one engaging protrusion 8 and one anti-rotation protrusion 9 are provided in the embodiment, the same engaging protrusion as the anti-rotation protrusion can be adopted to further improve the engagement strength. Further, the number of the rotation preventing projections and the engaging projections is not limited to one, and a plurality of them can be provided respectively. Further, the shape of the recessed groove 5 of the pipe holding portion 6 is not limited to the embodiment, and can be appropriately changed according to the number of pipe-shaped pipes and the like. Furthermore, in the embodiment, the clamp member 2 and the clamp band 3 are attached to the flat floor panel 4, but the clamp member 2 and the clamp band 3 may be attached to a curved floor panel.
