Description

[Detailed Description of the Invention] (a) Technical Field of the Invention The present invention relates to a support structure for an overflow hose in a reserve tank, which allows the overflow hose to be positioned according to specifications within the engine room.

(b) Prior art and problems Generally, in a reserve tank attached to a radiator, an overflow hose is connected to the top of the reserve tank body to release overflow water and pressure to the outside air. In the case of the conventional rubber overflow hose disclosed in the publication, one end is free and the entire hose is swingably attached, so the water released by overflow is spread over a wide area in the engine room. However, as a result, there were problems such as water heating up and staining harnesses and other equipment.

Therefore, in order to prevent overflow water from spreading and to position and fix the above-mentioned overflow hose in a position where water does not drip onto harnesses, etc., this overflow hose is molded with resin.
At the same time as blow molding the reserve tank, a mold is made and an overflow hose locking piece c is integrally molded on the parting line b on the side of the reserve tank a, as shown in Figure 6, to lock this overflow hose. Overflow hose d was locked to piece c and its position was determined.

However, in the conventional structure in which the overflow hose locking piece c is always integrally molded at a specific position of the reserve tank a, the attachment position of the overflow hose d is always restricted to one place. becomes. Therefore, the reserve tank a is
When installed on vehicles with different engine room specifications, the overflow hose d may have to be fixed in a position where overflow water will drip onto the harness etc. due to the structure. However, there were problems such as the inconvenience of having to install a different type of reserve tank, and the reduction in installation efficiency. Also, to prevent water from dripping onto the harness etc.
When an overflow hose (not shown) with a longer free end portion d' from the part that is locked to the overflow hose locking piece c is connected, a support member is provided to support the free end portion d'. In some cases, the free end portion d' may swing, which is not necessarily desirable.

In addition, there are other publications disclosing the hose attachment structure to the reserve tank, such as Utility Model Publication No. 55-92029.
No. exists.

(c) Purpose of the invention This invention was devised in view of the actual situation.
When the same reserve tank is installed in various specification cars with different layouts and specifications of harnesses and other equipment in the engine room, we have installed this to prevent water from overflowing and dripping onto the harness etc. To provide a support structure for an overflow hose in a reserve tank, which can appropriately position and lock the overflow hose at a required position.

(d) Structure of the invention In order to achieve this purpose, the support structure for the overflow hose in a reserve tank according to the invention is such that, in a reserve tank that has an overflow hose on the upper part of the tank body, It is characterized in that a protrusion is provided on the protrusion, and an overflow hose locking member is detachably attached to the protrusion.

(e) Effect of the invention According to the invention, the overflow hose locking member can be selected as appropriate depending on the specifications of the engine room.
If you prepare an overflow hose and attach it to the protrusion of the reserve tank, you can attach the overflow hose to vehicles of various specifications without contaminating harnesses, etc. with overflow water.

(F) Embodiments of the invention Hereinafter, embodiments of the invention will be described in detail based on FIGS. 1 to 5.

In the figure, 1 is a reserve tank formed by blow molding, and on the parting line 2 on the upper surface of the reserve tank 1, there is a reserve tank 1 formed by blow molding.
A protrusion 3 having a T-shaped cross section, which was formed at the time of blow molding, is integrally attached. An overflow hose locking plate 5 through which an overflow hose 4 made of resin is inserted is detachably attached to the projection 3.

As shown in Fig. 3, this overflow hose locking plate 5 is a resin plate with a slightly narrow width on both sides of the center, and an overflow hose insertion hole 6 is bored in one end of the plate, and an overflow hose insertion hole 6 is bored in the other end. A protrusion insertion/removal hole 7 into which the protrusion 3 can be freely inserted and a protrusion locking hole 8 for locking the protrusion 3 are bored in the. The protrusion insertion/removal hole 7 and the protrusion locking hole 8 communicate with each other via a communication hole 9 whose width is slightly narrower than the diameter of the shaft portion 3a of the protrusion 3.
Incidentally, in order to attach this overflow hose locking plate 5 to the reserve tank 1, as shown in FIG.
is moved in the direction of arrow A, and the protrusion 3 is inserted through the communication hole 9.
The communication hole 9 is narrower than the shaft portion 3b of the projection 3.
The movement of the protrusion 3 into the protrusion insertion/removal hole 7 is restricted to prevent the locking plate 5 from coming off from the reserve tank 1.

In addition, in the figure, reference numeral 10 indicates a mounting bracket for the reserve tank, reference numeral 11 indicates a mounting piece integrally formed with the reserve tank 1, and reference numeral 12 indicates a reserve hose connected to a radiator (not shown).

Since this embodiment is configured as described above, when installing the reserve tank 1 in the engine room, the overflow hose 4 is installed in a position that prevents overflow water from dripping onto the harness (not shown) etc. according to the specifications of the engine room. Prepare an overflow hose locking plate 5 suitable for the vehicle type that can position the It will be positioned at the position. In addition, in the case of a vehicle with the same specifications as the vehicle model, by locking the overflow hose 4 to the overflow locking plate 5 and attaching it to the protrusion 3, the overflow hose 4 can be placed in a position where overflow water will not always splash onto the harness, etc. Positioning can be done in the same way.

Furthermore, if the reserve tank 1 provided with this embodiment is installed in another car model with different specifications in the engine room, an overflow of a length that is compatible with the specification car and that allows the overflow hose 4 to be positioned at the required position is provided. After inserting the overflow hose 4 into the hose locking plate 5a, the locking plate 5 is rotated around the protrusion 3 to the above-mentioned required position.
Just attach a. Therefore, when positioning the overflow hose 4, simply use the locking piece 5.
It is now possible to attach the overflow hose 4 to a desired position where overflow water does not splash onto the harness etc., even in various vehicle models with different specifications. In this embodiment, the protrusion 3 is integrally formed on the parting line 2, but it may also be provided by being fused to other parts of the reserve tank 1. It goes without saying that the present invention is not limited to a tank with a reserve hose connected to it, but can also be applied to a type of reserve tank in which a reserve hose is connected to the upper part of the tank body. Furthermore, in the above embodiment, after the overflow hose 4 was inserted into the overflow hose locking plates 5, 5a, the locking plates 5, 5a were attached to the reserve tank 1. , 5a to the reserve tank 1, the overflow hose 4 is attached to the corresponding locking plates 5, 5.
They may be inserted into a, and the order in which they are installed is not particularly specified.

(g) Effects of the invention As described above, according to the invention, the overflow hose can be positioned and fixed at a desired location where overflow water will not splash onto the harness, etc., for all types of vehicles with different specifications in the engine room. became possible.
