Description

FIELD OF TECHNOLOGY

The utility model relates to sealing devices for metering the consumption of resources - water, gas and electricity meters.

Sealing of metering devices with indicator devices containing magnetically sensitive elements is widely used by operating organizations for the purpose of detecting unauthorized influence on metering devices with a magnet in order to slow down and / or completely stop their operation in order to distort the readings of the meter and steal the corresponding resources.

LEVEL OF TECHNOLOGY

Known is a magnetic field indicator having a sealed housing containing a non-magnetic base made with the possibility of fixing on an uneven surface, a magnetic strip placed on a non-magnetic base, and the magnetic strip contains an indicating element made of magnetically sensitive material and having a first geometric shape, and the indicating element is made with the ability, after breaking the first geometric shape, to restore the first geometric shape or to take the second geometric shape when exposed to an external magnetic key or magnetic seal, while a cover made of a non-magnetically sensitive transparent polymeric material is installed on a non-magnetic base (see Patent RU 154039). The description of the known utility model contains an indication of the possibility of placing the indicator on the sealing tape.

However, in the known utility model, the seal made of sealing tape is not protected against being removed from the meter by heating.

Heating of stickers made of filling material for the purpose of their unauthorized removal without triggering (without displaying an opening inscription) by heating them has recently become widely used by unscrupulous consumers of the corresponding resources. The sticker heats up (for example, by a stream of hot air) and can be easily removed from the meter without any damage, which allows unscrupulous consumers to steal the corresponding resources. Thus, a failed indicator device can be re-placed on a metering device and in case of actual theft of resources, the operating organization is deprived of the opportunity to prove the fact of theft.

DISCLOSURE OF THE USEFUL MODEL

The technical result to which the claimed utility model is directed is to improve the quality of the indicator device by eliminating the possibility of secretly removing the sticker or magnetically sensitive element from the meter by heating the sticker.

The claimed technical result is achieved due to the fact that the indicator device for visual monitoring of the effect of a magnet on metering devices for water, gas and electricity consumption includes a sealed plastic case, which houses a magnetically sensitive element made of a magnetically sensitive material with an image applied to it, which disappears when exposed to magnet, the base of the case is mounted in a sticker made of a sealing material that changes color and displays an opening message when trying to remove the sticker or magnetically sensitive element, and the sticker is equipped with an additional security measure in the form of a heat-sensitive paint applied to it, which changes color when an attempt is made to unauthorized removal of the indicator device from the device metering by heating the sticker.

The applicant has not found sources of information containing the same set of essential features indicated in the formula of the utility model, which allows us to conclude that the claimed technical solution meets the criterion of patentability of the utility model “novelty”.

BRIEF DESCRIPTION OF DRAWINGS

The declared utility model is illustrated with graphic material, where:

FIG. 1 shows a general view of the indicator device;

FIG. 2 shows a general view of the indicator device when exposed to a magnet;

FIG. 3 shows a general view of the display device when trying to remove it by tearing off the sticker;

FIG. 4 shows a general view of the indicator device when trying to remove the sticker by heating.

IMPLEMENTATION OF THE USEFUL MODEL

Indicator device, including a sealed plastic case (1), which houses a magnetically sensitive element made of magnetically sensitive material with an image (2) applied to it, which disappears when exposed to a magnet, and the base of the case is mounted in a sticker made of a filling material (3) that changes color and showing the tampering message when trying to remove the sticker (4) or magnetically sensitive element, and the sticker is provided with additional security in the form of a heat-sensitive paint (5) applied to it, which changes color when an attempt is made to unauthorized removal of the indicator device from the meter by heating the sticker.

The indicator device works as follows. A sealed plastic case (1) is mounted in a sticker made of filling material (3), on which a heat-sensitive paint (5) is applied, which changes color when heated, in which a magnetically sensitive element (2) is placed, made of a magnetically sensitive material with an image applied to it, disappearing when exposed to a magnet. When a magnet acts on a metering device, the image applied to the magnetically sensitive element disappears, which makes it possible to make an unambiguous conclusion about the effect of a magnet on the metering device. When you try to replace the case with a magnetically sensitive element placed in it, by tearing off, a sticker is triggered and a corresponding inscription appears. When re-gluing, the displayed inscription does not disappear. When you try to remove the indicator device from the meter by heating, the heat-sensitive paint applied to the sticker changes color. When it cools down after triggering, the color of the heat-sensitive paint does not change and remains the same as when heated, which makes it possible to make an unambiguous conclusion about an attempt to remove the indicator device.

The magnetically sensitive element can be made of magnetic paper or magnetic film on which the image is applied by magnetization.

For ease of use, an individual number and / or a tear-off coupon duplicating such a number can be placed on the display device.

Claims (1)

An indicator device for visual monitoring of the effect of a magnet on metering devices for water, gas and electricity consumption, including a sealed plastic case, in which a magnetically sensitive element is located, made of a magnetically sensitive material with an image applied to it, which disappears when exposed to a magnet, and the base of the case is mounted in a sticker from a filling material that changes color and displays an opening message when trying to remove a sticker or a magnetically sensitive element, characterized in that the sticker is equipped with an additional security device in the form of a heat-sensitive paint applied to it, which changes color when an attempt is made to unauthorized removal of the indicator device from the meter by heating the sticker.
