Description

[Detailed description of the invention] <Technical field> This invention relates to a liquid tank that has a liquid level gauge on its outer surface, such as a cartridge tank for an kerosene heater, and particularly relates to a protection device for the liquid level gauge. be.

<Prior art> In Fig. 2, numeral 1 indicates a cartridge type tank of an kerosene heater having elongated holes 2 at appropriate locations on its outer surface, and numeral 3 indicates a transparent liquid level meter body 4 made of glass, synthetic resin, etc.
and an index 5 provided in the longitudinal direction on the back side of the main body 4, 6 is a gasket fitted around the entire outer periphery of the liquid meter main body 4, and 7 is a long hole 2 of the tank 1. A gasket cover 8 is used to clamp the gasket 6 between the peripheral edge and the gasket 6. The gasket cover 7 and the gasket 6 are sequentially inserted into the screw hole 1a of the tank 1, and the liquid meter 3 is placed opposite the long hole 2. These are screws that hold it in place.

<Problems to be solved by the invention> However, in such a conventional example, since the surface of the liquid level gauge 3 is slightly protruded outward, foreign objects may collide with the tank 1 or the tank 1 may be damaged. If it hits a foreign object while carrying it, there is a risk that the foreign object will hit the liquid level gauge 3 directly and damage the liquid level gauge 3, which may lead to an accident in which the liquid level gauge 3 is damaged and the liquid spills out. Ta.

In such a liquid tank, the present invention prevents the liquid level meter from directly hitting foreign objects by forming a protective part around the outer periphery of the liquid level meter that protrudes outward from the surface of the liquid level meter. The present invention is characterized in that it is possible to avoid the inconvenience of liquid flowing out due to damage to the liquid meter.

<Means for Solving the Problems> A protective portion 9 is provided by standing up the inner circumferential portion of a packing cover 7 that covers the packing 6 fitted to the outer peripheral edge of the liquid level meter 3 of the liquid tank. The tip of this protective portion 9 is made to protrude outward from the surface of the liquid level meter 3.

<Function> (1) Since the protective portion 9 protrudes outward from the surface of the liquid level meter 3, it prevents foreign objects from directly hitting the liquid level meter 3.

(2) Since the protection part 9 is formed by standing up the inner peripheral part of the seal cover 7,
In particular, it also plays a role of reinforcing the inner periphery. That is, when a foreign object hits the tip of the protection part 9, the packing cover 7 itself is prevented from being deformed.

<Embodiment> In the embodiment shown in FIG. 1, 1 is a cartridge type tank of an kerosene heater having long holes 2 at appropriate places on the outer surface, 3 is a transparent liquid meter body 4 made of glass, synthetic resin, etc.; 4 and an indicator 5 provided in the longitudinal direction on the back side, 6 is a gasket fitted around the entire outer periphery of the liquid meter body 4, and 7 is a gasket that is connected to the periphery of the elongated hole 2 of the tank 1. A seal cover 8 holds the seal 6 between them, and the seal cover 7 and the seal 6 are inserted in sequence and screwed into the screw hole 1a of the tank 1, and the liquid level meter 3 is fixed in a position facing the long hole 2. It's a screw. Reference numeral 9 denotes a protective wall (protective part) formed upright on the outer periphery of the liquid meter 3, for example, on both sides in the longitudinal direction, on the gasket cover 7, and is used to prevent foreign matter from protruding outward from the surface of the liquid meter 3, that is, the surface of the liquid meter main body 4. is the liquid level meter 3
This prevents direct contact with the

In this embodiment, if a foreign object collides with the tank 1 or hits a foreign object while carrying the tank 1, the protection part 9 receives the impact, so the liquid level gauge 3 Therefore, accidents such as oil leakage due to damage to the liquid level meter 3 can be prevented.

<Effects> (1) The protective part formed on the inner periphery of the seal cover prevents foreign objects from directly hitting the liquid meter, thereby avoiding accidents such as liquid leakage due to damage to the liquid meter.

(2) In addition, the above protection part also serves to reinforce the inner periphery of the gasket cover, so it reduces the distortion of the gasket cover when it receives an impact from a foreign object, and protects the liquid level meter from a larger impact caused by a foreign object. can be protected.

Incidentally, even if the thickness of the packing cover is the same as before, if the thickness of the packing itself is made thicker as shown in Figure 3, the packing cover will be positioned outward from the surface of the liquid level meter, and foreign matter will not directly reach the liquid level meter. prevent hitting. However, the inner periphery of the packing cover is flat and weak, and the packing itself is elastic, so if a strong impact from a foreign object causes the packing to dent, the inner periphery of the packing cover will also deform. As a result, the foreign object ends up hitting the liquid meter.
