Description

[Detailed Description of the Invention] The present invention relates to a structure for attaching a liquid injection hose to a vehicle body, which is connected to a liquid storage tank such as a washer tank installed in an automobile.

2. Description of the Related Art In modern automobiles, a large number of mechanisms are installed in the engine compartment, so the space within the engine compartment is becoming smaller, making it difficult to install a washer tank in the engine compartment.

Therefore, as shown in Fig. 1, a washer tank 3 is installed in the space formed between the outer panel 1 and the inner panel 2 of the vehicle body, but in this case, the fluid filling port of the washer tank 3 is Since it must be installed in a location where it is easy to handle liquids, a bellows-shaped flexible hose 1 made of a soft resin material is connected to the inlet of the washer tank 3, and the opening at the end of this flexible hose 4 is used to inject liquid into the vehicle body. It is easily installed in the desired position.

In this mounting structure, a metal bracket 5 is conventionally attached to the outer panel 1 as shown in FIG.
This is done by fitting an annular groove 7 provided on the outer periphery of the opening at the tip of the flexible tube 4 into a U-shaped notch 6 provided in the tube.

However, in such a case, when the cap 8 is fitted into the opening at the tip end of the flexible tube 4, the flange 9 of the flexible tube 4 is pressed by the cap 8 as shown by the dotted line in FIG. If the cap 8 is fitted too tightly, the flexible tube 4 may come off from the bracket 6, which makes it difficult to fit the cap 8 smoothly.

The object of the present invention is to provide a structure for mounting a liquid injection hose on a vehicle body, which can eliminate the drawbacks of the conventional ones as described above.

The present invention will be explained in detail below based on the embodiments shown in FIGS. 4 to 6.

4 and 5, reference numeral 10 denotes a bracket made of hard resin that is attached to the outer panel 1 of the vehicle body. A thin piece 14 connecting the outside of the cylindrical part 11 is integrally formed.

Reference numeral 15 denotes a flexible tube made of a soft resin material, and a distal end opening 16 of the flexible tube 15 is formed to fit into the cylindrical portion 11 described above.

Reference numeral 17 denotes an annular groove formed on the outer periphery of the flexible tube 15, and the annular groove 17 is adapted to be engaged with an inward flange 18, which is an engaging portion formed at the lower opening edge of the cylindrical portion 11. It is formed.

Further, the relationship between the annular groove 17 and the flange 18 may be reversed.

Reference numeral 19 is a distal flange formed in a bulge on the opening edge of the flexible tube 15, and 20 is a protrusion formed on the upper opening edge of the cylindrical portion 11, on which the distal end flange 19 overlaps. Furthermore, the protrusion 20 is adapted to be engaged with a protrusion 21 formed on the inner peripheral surface of the cap 13.

Reference numeral 22 denotes a protrusion that protrudes from the lower side of the flat plate portion 12 and further has a slit 23 for air venting, and an air venting pipe 24 that does not completely block the slit 23 is connected to this protrusion 22. ing.

25 is a mounting screw fixing the bracket 10 to the outer panel 1, and 26 is a filter.

Next, to describe its function, a washer tank (not shown) is attached to the bracket 10 fixed to the outer panel 1.
To connect the flexible tube 15 connected to the
is crushed to reduce its outer diameter as shown by the broken line in FIG.
At the same time, the annular groove 17 of the flexible tube 15 is engaged with the flange 18 of the cylindrical portion 11 to connect the bracket 10 and the flexible tube 15.

Then, by closing the cap 13 and engaging the protrusion 21 of the cap with the protrusion 20 of the cylindrical portion 11, the tip flange 1 formed at the mouth edge of the flexible tube 15 is removed.
9 is elastically pressed between the protrusion 20 of the cylindrical portion 11 and the cap 13 to seal the opening of the flexible tube, thereby achieving an effective seal.

As shown in FIG. 6, approximately semicircular grooves 27 are formed in the flexible tube 15 at symmetrical positions in the circumferential direction, and the cylindrical portion 11 is further provided with approximately semicircular grooves 27 that are engaged with each groove 27. Stop part 2B
If the locking portion 28 is engaged with the groove 27, the cylindrical portion 11 and the flexible tube 15 are integrally connected. According to this embodiment, the flexible tube 15 can be rotated. This has the effect of being connected to the cylindrical portion 11 without being moved.

As described above, the present invention provides a protrusion or groove extending in the circumferential direction on the outer periphery of the tip opening of the liquid injection hose connected to the liquid storage tank, houses the tip opening of the liquid injection hose in the bracket, and stores the tip opening of the liquid injection hose in the bracket. Since a cylindrical part is provided with an engaging part that engages with the groove, and the cap is attached to the upper end opening of the cylindrical part, it is possible to attach the liquid injection hose to the bracket very simply and easily. It is easy to attach and detach, and the injection hose will not come off the bracket.

In addition, in the present invention, since the liquid injection hose is sandwiched between the bracket and the cap, sealing can be performed reliably without using any special packing.
