Description

[Detailed Description of the Invention] The present invention relates to a positioning device for a liquid supply pipe, such as a pump pump, which has a function of detecting the liquid level and automatically stopping the operation.

In such a pump, a discharge hose is connected to a branch section provided in the pump body, and the other end of this hose is connected to the discharge section. In FIG. 1, 1 is a branch part of the pump body, 2 is a discharge hose, and 3 is a discharge part. This discharge part 3 has a built-in liquid level detector (not shown) at its tip, and when this is attached, for example, when refueling the oil tank of an kerosene heater, oil is supplied by the operation of the pump and the liquid becomes liquid. When the surface rises and reaches the detector, it emits a signal that is routed to a control circuit that automatically stops the oil supply to prevent overflow. However, since the liquid level detector is installed at the tip of the discharge part, it must be inserted into the hanging part of the tip when refueling, which makes it difficult to regulate the degree of insertion and the level of the refueled liquid tends to fluctuate. There were flaws. In order to eliminate such drawbacks, a plurality of locking folds are provided on the outer surface of the part that continues to the tip of the discharge part, and when a particular force is further applied to this part, it is possible to move over the locking folds. An adjustment ring having a flexible opening at least around the periphery was attached so as to ensure the following. 4 in FIG. 1 is an adjustment ring.
Move this ring to an arbitrary position in the discharge part, and as shown in FIG.
If the discharge part 3 is set to correspond to the liquid level 12, it is possible to automatically supply oil up to the liquid level 12 according to the setting.

However, it is difficult to move the ring attached to the discharge portion over the locking folds to a desired position without applying special force, which is extremely inconvenient. Further, when refueling after adjusting the ring by moving it between the desired locking folds, it was time-consuming to place the ring on the edge of the filler port of the refueling tank and support it by hand, which caused problems in holding the ring.

The present invention eliminates the above-mentioned drawbacks and provides an improved positioning device for a liquid supply pipe that enables extremely efficient liquid supply, the adjustment being fitted into the discharge part of the liquid supply device. The ring is improved so that the adjustment ring can be easily moved and the discharge part can be stably held during liquid supply.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 3 shows the outer shape of an embodiment of the present invention, FIG. 4 shows the outer shape of the discharge part of the present invention, and FIG. 5 shows a sectional view of the discharge part fitted with the adjustment ring of the present invention. As shown in FIG. 3, a discharge hose 22 is connected to a branch part 21 of the main body of the pump, and a discharge part 23 is connected to the other end of the discharge hose 22. This discharge section 23 is shown in FIG. Discharge part 23 corresponding to the position of the liquid level detector built in the discharge part
An indicator ring 24 is provided on the outer surface of the tip end, and a plurality of locking folds 25 are provided on the outer surface of the portion following this. This discharge part 23 has an adjustment ring 26.
A clip 27 is fixed to one end of the adjustment ring 26, and a leaf spring 28 is inserted to apply a force to the one end 29 of the clip 27 to move it closer to the outer surface of the discharge portion. The display ring 24
is fitted between two protruding rings 30 formed on the outer surface of the discharge part, and has a yellow color that can be easily identified, unlike when the discharge part is black, for example. FIG. 5 shows the adjustment ring 2 fitted to the discharge part 23.
6 is shown. That is, an annular spring 31 made of an elastic body is disposed inside the adjustment ring 26, and this annular spring 31 has locking ribs 32 that are protruded from the inside to face each other, and a direction in which the ribs 32 are formed. It has mutually opposed, integrally formed push buttons 33 projecting outside the adjustment ring in a right angle direction.

When using a discharge part equipped with such an adjustment ring, for example, when refueling a tank, it is extremely easy to stably position the discharge part at the desired position depending on the liquid level setting, such as how far into the tank the oil should be filled. It can be fixed and automatically refuel up to the liquid level according to the setting. For example, as shown in FIG. 6, when refueling a tank 40 up to the liquid level 41 in the tank, the discharge part 23 is inserted through the inlet 42 of the tank, and the display ring 24 of the discharge part is moved to the predetermined position. The discharge part 23 may be sufficiently fixed by aligning it with the liquid level and clamping the edge 43 of the inlet with a clip 27 fixed to the adjustment ring to supply oil. Such setting of the discharge part can be achieved by freely moving the adjustment ring in the axial direction of the discharge part and locking it in a predetermined locking fold that allows the above-mentioned setting. The ring of the present invention, which incorporates the annular spring made of an elastic body, can be moved very easily without requiring any force. In other words, when you press the push button toward the center as shown by the arrow (→), the annular spring flexes in the direction perpendicular to this as shown by the arrow (ⓓ), and the locking rib can release the locking pleat, making it easy to adjust. The ring can be moved very easily.

When you fix the discharge part to the filler port in this way and start refueling, the display ring has a clear color that can be distinguished from the color of the discharge part, so the display ring allows you to refuel to the desired liquid level. The position of the tank is easy to adjust, the liquid level can always be refilled at a constant level, and the clip securely secures the discharge part to the tank, so there are no problems with attaching the discharge part as in the past. The discharge part can be maintained at a constant level extremely efficiently, and the tank can be refilled to the desired liquid level.

The above explanation is about pouring oil into a tank, but it is not limited to this, but it can be used to supply not only oil but also various liquids to a certain level in various containers to achieve the same excellent effect. It shows.
In addition, the color display on the display ring is not limited to the above-mentioned colors.
Any color that is clear and easily distinguishable in relation to the color of the discharge part may be used. Furthermore, it goes without saying that the present invention is not limited to what has been shown and described above, and there are variously modified structures as a positioning device for a liquid supply pipe used in a pump or the like according to the gist of the present invention.
