Description

[Detailed Description of the Invention] The present invention relates to a waterproof scale that prevents water from entering the scale body.

Generally, in a scale, an interlocking rod fixed to the underside of the weighing platform is introduced from the upper end of the scale body into the inside of the scale body and connected to a weighing mechanism, and the interlocking rod is lowered according to the weight of the object to be weighed on the weighing platform. The structure is such that the amount of descent is measured by a weighing mechanism.

However, with conventional scales of this type, water can enter the body through the interlocking rod insertion hole provided at the top of the scale body, shortening the life span or causing malfunctions of the weighing mechanism within the body. There were problems such as allowing the Moreover, it is difficult to remove water that has entered the scale body, so when washing the surface of the scale, extreme care must be taken to prevent water from entering the scale body.

The present invention has been developed in consideration of these circumstances, and its purpose is to provide a waterproof scale that has a simple structure and can reliably prevent water from entering the scale body.

EMBODIMENT OF THE INVENTION Hereinafter, the structure of this invention is demonstrated based on the Example shown in drawing.

FIG. 1 shows the external appearance of the scale. In the figure, 1 is a scale main body that includes a weighing mechanism (not shown), and 2 is a weighing platform on which an object to be weighed is placed. An interlocking rod 3 is fixed to the lower surface of the weighing platform, and the interlocking rod 3 is introduced into the scale body 1 through a hole 5 provided in the upper plate 4 of the scale body 1 as shown in FIG. It is connected to the weighing mechanism. When an object to be weighed is placed on the weighing platform 2, the weighing platform 2 descends by an amount corresponding to its weight, and the amount of descent is measured by the weighing mechanism and displayed in accordance with the weight.

FIGS. 2 and 3 show the "" part in FIG.
A cylindrical portion 6 is provided in a protruding manner so as to communicate with the upper plate portion 4 (for example, the lower end flange portion is fixed to the upper plate portion 4 by welding). The outer periphery of this cylindrical portion 6 is
A cap-shaped (conical tube-shaped) buttful plate 7 is attached which slopes downward from approximately the central height position toward the outside. On the other hand, a bottomed cylindrical outer tube 8 is attached to the lower surface of the weighing platform 2 with the opening facing downward, and a small-diameter inner tube 9 is coaxially attached to the inner bottom surface of this outer tube 8. The interlocking rod 3 is positioned on the center line of the outer cylinder 8 and the inner cylinder 9. The outer cylinder 8 has an inner diameter and length that surrounds the buff-full plate 7 without contact, while the lower end of the inner cylinder 9 is close to the upper surface of the buff-full plate 7 with an appropriate gap.

With the above configuration, even if the outer surfaces of the scale body 1 and the weighing platform 2 are washed with water, water will not enter into the scale body 1 through the holes 5. In other words, even if the cleaning water tries to enter the inside of the scale body 1, most of the water will become brittle when it enters the inside of the outer cylinder 8 through the gap between the lower end of the outer cylinder 8 and the scale main body 1, as shown by the arrow in the figure. Water that hits the lower surface of the plate 7 and flows down, and slightly enters the upper surface side of the buttful plate 7 through the gap between the outer cylinder 8 and the buttful plate 7, is also almost completely absorbed by the outer cylinder 8 and the inner cylinder 9.
After rising between the two, the liquid flows directly to the outside from the inner bottom surface of the outer cylinder or the outer circumferential surface of the inner cylinder 9, or flows down along the upper surface of the baffle plate 7. Even if it occasionally penetrates into the inside of the inner cylinder 9 through the gap between the buttful plate 7 and the inner cylinder 9, it is unlikely that it will penetrate beyond the upper end of the cylindrical part 6 and into the inside thereof. Since it is almost impossible, in the end,
It is possible to reliably prevent water from entering the scale body 1 from the outside through the cylindrical part 6.

In the above embodiment, the cylindrical part 6, the full plate 7, the outer cylinder 8, and the inner cylinder 9 are all circular, but they may be rectangular cylinders as shown in FIG. ', 7', 8', 9'), the interlocking rod 3 may also be square (indicated as 3').

As described above based on the embodiments, according to the present invention, it is possible to prevent water from entering the scale body with an extremely simple structure, and it can be washed with water without paying special attention. A waterproof scale having excellent practical effects can be provided.
