Description

Technical Field

[0001] The utility model relates to the technical field of electronic scales, in particular to a device with a function of preventing electronic scales from being disassembled. Background Art

[0002] Digital indicator scales are easy to weigh, simple to calculate, and intuitive to display. They are widely used in markets, supermarkets, fixed vendors, mobile vendors, night markets, and other fields. However, many illegal vendors violate the principle of honest business and choose to use cheating scales in pursuit of profits. There are a large number of short-weight and short-weight cases in the market, which seriously infringes on the interests of consumers and has caused public opinion hotspots many times in 2023. At the same time, in order to avoid investigation by regulatory authorities, the cheating methods of electronic scales are constantly upgraded. Installing cheating switches and using remote controls to cheat have been basically eliminated because they are not concealed. At present, electronic scales on the market basically rely on software cheating, that is, replacing the motherboard with cheating function or replacing the program in the original motherboard chip with a cheating program, starting the cheating mode by entering a password, and calling different calculation parameters to change the weight indication. When you need to restore normal mode, you only need to turn off the power by turning the machine on and off. Because cheating data and processes are difficult to record, regulatory authorities lack evidence for law enforcement. For example, after the cheating program is implanted, the scale is put into cheating mode by pressing the tare key and entering a password, such as 323. Then, the scale enters cheating mode by pressing the function key "M 1". The weight indication is 110% of the original value. By pressing the "M2" key, the weight indication is 120% of the original value. By restarting the machine to exit cheating mode, the scale returns to normal. The cheating keys can be combined at will, which is extremely secretive.

[0003] After searching, the existing patent (publication number: CN219532263U) discloses an electronic scale including: a weighing plate, a mounting column, a connecting assembly, a first display screen and a second display screen. The first display screen is connected to the mounting column through a single cantilever structure of an adapter arm, and the first display screen can rotate relative to the mounting column through the adapter arm, so that the first display screen can be better close to consumers in scenes with wider countertops and piles of goods in front of the counter, so as to facilitate consumers to timely understand the information about purchased goods, thereby improving the comfort of product use. In addition, the first display screen can rotate relative to the adapter arm, and in conjunction with the first display screen being able to rotate relative to the mounting column through the adapter arm, the first display screen can flexibly adapt to various complex scenes. In addition, the second display screen can achieve large-angle rotation adjustment relative to the connecting arm, so that the second display screen can flexibly adapt to countertops of various heights, so that the second display screen always faces the merchant at a suitable angle.

[0004] However, to modify a cheating scale, the electronic scale must first be disassembled, so cheating scales on the market are basically not sealed. However, electronic scales in fields such as markets are used in harsh environments, and the lead seals are exposed. Many normal scales do not have lead seals. Secondly, many electronic scales use universal lead seals, so it is not difficult to reseal the scales. Because this type of commonly used lead sealing method cannot prevent electronic scale cheating, there is a method that uses internal pressure sensors, photoelectric sensors and other detection elements to detect whether the bottom shell and the top shell of the electronic scale have been disassembled. However, this method has the problems of high cost and complex process, and is difficult to promote. In addition, it does not pay attention to the protection of the lead seal, and there is a problem of the lead seal falling off due to the harsh use environment.

[0005] Therefore, in order to solve the above problems, a device with the function of preventing electronic scale from being disassembled is proposed. Utility Model Content

[0006] 1. Technical issues to be resolved

[0007] In view of the deficiencies in the prior art, the utility model provides a device with an anti-disassembly function for electronic scales, which solves the problem mentioned in the above background technology that the electronic scales need to be disassembled first before they can be modified for cheating, so the cheating scales on the market are basically not sealed. However, electronic scales in fields such as markets are used in harsh environments, and the seals are exposed to the outside. Many normal scales do not have seals either. Secondly, many electronic scales use universal seals, so it is not difficult to reseal the scales. Because this type of commonly used seal method cannot prevent electronic scales from cheating, a method has been developed to detect whether the bottom shell and the face shell of the electronic scale have been disassembled by using detection elements such as pressure sensors and photoelectric sensors inside. However, this type of method has the problems of high cost and complex process, making it difficult to promote, and does not pay attention to the protection of the seals, and there is a problem of the seals falling off due to the harsh use environment.
