BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid outlet plug for a storage battery.

[0002]

2. Description of the Related Art A conventional storage battery, except for a sealed type, has a liquid port plug capable of being exhausted at its liquid injection port. The liquid stopper is
A gripping head having an exhaust hole and a cylindrical plug extending downward from the head, a threaded portion is provided on an upper outer peripheral surface of the cylindrical plug, and a splash-proof mechanism is provided therein. By applying this to the liquid injection port, the gas generated in the storage battery is exhausted to the outside, and the liquid mist contained in the gas is trapped by the splash-proof mechanism to prevent liquid leakage to the outside. Used to exhaust.

[Problems to be Solved by the Invention]
However, at the time of manufacturing the storage battery, after being automatically supplied to the liquid injection port of the battery case lid, in the automatic tightening process, it is screwed into the screw hole of the liquid injection port and tightened. The liquid plug cannot maintain the state of being supplied straight into the screw hole of the liquid injection port, and as shown in FIG. 5, the supplied liquid plug A is the liquid injection plug provided on the battery case lid B of the storage battery. Often, the screw hole D of the mouth C is inclined.
As a result, in the next automatic tightening process, there is a problem that the automatic tightening cannot be performed or the tightening becomes defective.
This is an obstacle to automatic battery manufacturing. Therefore, there is a demand for a storage battery liquid spout capable of eliminating such obstacles and performing continuous production by smooth automation of the storage battery.

DISCLOSURE OF THE INVENTION The present invention relates to a storage battery liquid port stopper that satisfies the above-mentioned demand, and comprises a head portion having an exhaust hole and a cylindrical stopper body extending downward from the head portion. has a screw thread portion on the upper outer peripheral surface of the cylindrical plug body, the storage battery for liquid spout comprising comprises a splash-proof mechanism therein, the lower peripheral surface of the tubular Josentai, and its lower peripheral surface The tubular plug is applied
A plurality of ribs are provided so as to be interposed in the gap between the liquid inlet of the battery case lid and the peripheral surface of the screw hole .

[0005]

When the liquid inlet plug of the present invention is supplied to the liquid inlet of the battery case lid of the storage battery, the liquid outlet plug is inserted into the screw hole of the liquid inlet in the hollow cylindrical plug body, The plurality of ribs arranged at the lower portion of the stopper body are interposed between the outer peripheral surface of the stopper body and the peripheral surface of the screw hole of the liquid injection port. The liquid is maintained in the vertically supplied state in the liquid injection. This ensures good tightening in the next automatic tightening step. In this case, by disposing three or more ribs at equal intervals or substantially equal intervals, the plurality of ribs surely brings about holding the plug body in a vertical state. Further, when the lower end portion of each rib is formed in a downward inclined surface, when the liquid mouth plug is supplied to the liquid injection port, it is guided by the downward inclined surface and inside the screw hole of the liquid injection port. The insertion into the is done smoothly.

Embodiments of the present invention will now be described with reference to the accompanying drawings. 1 to 3, reference numeral 1 denotes a liquid battery cap of an embodiment of the present invention. The liquid cap 1 is a gripping head 3 having an exhaust hole 2 on its top surface and the head. A cylindrical plug body 5 extending downward while leaving an annular packing mounting surface 4 on the lower surface of the portion 3. The cylindrical plug body 5 has a threaded portion 6 on its upper outer peripheral surface, and And a splash-proof mechanism 7. In addition, generally, a ventilation hole 8 is provided on the side surface of the lower portion 5a of the cylindrical plug body 5. In the drawing, 9 indicates an annular packing. The above is the same as the conventional liquid spout, but according to the present invention,
Bottom 5a of the tubular plug body 5, the screw hole 1 of circular pouring hole 12 provided on the container lid 11 of the battery indicating the outer diameter 4
The lower part 5a has such a size that a relatively large annular gap can be left between the liquid injection port and the liquid injection port so that 3 can be easily inserted.
A plurality of ribs 10 are arranged on the outer peripheral surface of the. The rib 10
Is a vertical extension that does not reach the lower end of the lower portion 5a, and the extent of the protrusion is such that the lower portion 5a of the cylindrical plug body 5 is in the screw hole 13 of the liquid inlet 12 of the battery case lid 11 of the storage battery. When inserted, there is a slight gap between it and the screw hole 13 so that it can be easily inserted and interposed , and the tilting of the cylindrical plug body 5 can be prevented. Further, the number of ribs 10 is usually preferably 3 or more, and in the illustrated example, four thin ribs 10,
10, 10, 10 are arranged at substantially equal intervals. Although the ventilation holes 8 shown in the drawing are at a 90 ° interval from the ribs 10, the positions thereof are displaced so that all the ribs 10 are exactly 90 degrees apart.
Needless to say, it may be evenly spaced. Although not shown in the case of three ribs, it is preferable to arrange them at intervals of 120 ° or in the vicinity thereof.

When the above-mentioned liquid mouth plug 1 of the present invention is supplied to the liquid injection port 12 of the battery case lid 11 of the storage battery by the automatic supply device, as shown in FIG. same time as the lower 5a is obtained effortlessly inserted into the screw hole 13 of the 12 of the infusion liquid inlet
The rib 10 arranged on the outer peripheral surface of the lower portion 5a is
Between the outer peripheral surface of the lower portion 5a of the cylindrical plug 5 and the screw hole 13
Since it is interposed in the gap, the cylindrical plug body 5 can ensure a vertical state.
Thus , the large-diameter threaded portion 6 at the upper part thereof is vertically supplied to the liquid injection port 12 while being engaged and mounted on the rim 12a of the liquid injection port 12. More specifically , in this supply state, the four ribs 10, 10, 10, 10 arranged on the outer peripheral surface of the lower portion 5a of the tubular plug body 5 of the liquid mouth plug 1 are provided with the screw holes 13 Therefore, the liquid mouth plug 1 is prevented from tilting and is held in the vertical state. Therefore, this ensures that the screwing in the next automatic tightening process is carried out smoothly and well. Therefore, in other words, the automatic continuous supply of the storage battery and the automatic continuous production of the storage battery by tightening are possible.

In this case, when the lower end of each rib 10 is formed on the downward inclined surface 10a, when the liquid port plug 1 is inserted into the liquid injection port 12, the downward inclined surface 10a is guided. The lower part of the liquid port plug can be smoothly inserted into the screw hole 12.

[0009]

As described above, according to the present invention , the screw hole of the liquid injection port of the battery case lid is formed on the outer peripheral surface of the lower part of the cylindrical plug of the liquid port plug.
Since a plurality of ribs intervening in the gap with the peripheral surface are provided, when the liquid inlet plug is supplied to the liquid inlet of the storage battery, a vertical state can be secured in the liquid inlet, and therefore the next screw tightening It can be ensured that the battery can be smoothly carried out, and the automatic supply process and the automatic tightening process in the storage battery manufacturing can be smoothly carried out. In this case, the vertical state can be stably maintained by arranging three or more ribs 10 on the outer peripheral surface of the lower portion at equal intervals or substantially equal intervals. Further, when the lower end portions of the ribs are formed in the downward inclined surface, the lower portion of the liquid port plug can be smoothly inserted into the liquid injection port.
