The aluminum plate is installed close to the top constriction of the scale shell, and a small spatial angle is maintained between the aluminum plate and the scale shell. This prevents people from using magnets to stick the device to the bottom of the aluminum plate, thereby increasing the weight of the aluminum plate and causing cheating. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-5 An anti-overload cheating electronic scale includes: an electronic scale housing 1, a support leg 2 connected to the bottom of the electronic scale housing 1, an electronic screen 3 on the outer wall of the electronic scale housing 1, shortcut keys 4 on the outer wall of the electronic scale housing 1, a handle slot 5 on the outer wall of the electronic scale housing 1, a cavity 6 at the bottom of the electronic scale housing 1, a weighing machine 7 installed in the inner cavity of the electronic scale housing 1, a heat dissipation mesh 8 at the bottom of the weighing machine 7, a fixing ring 9 on the outer wall of the weighing machine 7, a load cell 10 sleeved on the inner wall of the fixing ring 9, a sensitive sensor 11 connected to the top of the load cell 10, a rubber pad 12 placed on the top of the load cell 10, an aluminum plate 13 placed on the top of the electronic scale housing 1, and a storage slot 14 on the inner wall of the aluminum plate 13.
[0023] The device has four support legs 2, which are evenly distributed at the bottom of the electronic scale housing 1. The four support legs 2 on the device are positioned at the four corners of the bottom of the electronic scale housing 1, and the electronic scale housing 1 stands on the ground using the support legs 2, thus making the device stable as a whole.
[0024] The device has two handle slots 5, which are located on both sides of the electronic scale housing 1. The two handle slots 5 are recessed on both sides of the electronic scale housing 1, allowing the electronic scale housing 1 to be lifted manually.
[0025] The cavity 6 is located in the bottom rear half of the electronic scale housing 1, and the cavity 6 is connected to the weighing machine 7 through the heat dissipation net 8. By setting the cavity 6 in the bottom rear half of the electronic scale housing 1, the cavity 6 in the device is connected to the outside air, and the heat dissipation net 8 is in contact with the outside through the cavity 6, so that the weighing machine 7 in the device can dissipate heat from the heat dissipation net 8.
[0026] The inner wall size of the fixing ring 9 is adapted to the outer wall size of the load cell 10, and the height of the fixing ring 9 is half that of the load cell 10. By adapting the inner wall size of the fixing ring 9 to the outer wall size of the load cell 10, the load cell 10 is installed in the inner cavity of the fixing ring 9. The load cell 10 is electrically connected to the weighing machine 7, and the fixing ring 9 fixes the circumference of the load cell 10 without affecting the weighing function of the load cell 10.
[0027] The weighing sensor 10 consists of four weighing sensors 10, which are evenly distributed on the outer wall of the weighing machine 7. The four weighing sensors 10 on the device are symmetrically and evenly distributed on the top of the weighing machine 7. The weighing sensors 10 are connected to the sensing head 11 above and the weighing machine 7 below, thereby transmitting the sensing data of the sensing head 11 to the weighing machine 7.
[0028] The inner wall size of the rubber pad 12 is adapted to the outer wall size of the sensitive sensor 11, and the sensitive sensor 11 is located directly below the aluminum disk 13. By adapting the inner wall size of the rubber pad 12 to the outer wall size of the sensitive sensor 11, the sensitive sensor 11 bears the weight at the bottom of the aluminum disk 13, and when the sensitive sensor 11 receives pressure, it contracts into the inner cavity of the load cell 10. Thus, when the sensitive sensor 11 bears the weight, the rubber pad 12 prevents the sensitive sensor 11 from being damaged by the weight or from losing its connection with the load cell 10.
[0029] The electronic scale housing 1 has a loading cavity 15 inside, and the size of the inner wall of the loading cavity 15 is adapted to the size of the outer wall of the weighing machine 7. By having a loading cavity 15 inside the electronic scale housing 1, the loading cavity 15 inside the electronic scale housing 1 provides loading space for the weighing machine 7, and the weighing machine 7 is installed in the inner cavity of the loading cavity 15.
[0030] The working principle involves first setting up a sensitive sensor 11, a rubber pad 12, an aluminum plate 13, and a weighing machine 7. When an object is placed inside the aluminum plate 13, its weight is transmitted to the sensitive sensor 11, which senses the weight. If the pressure on the sensitive sensor 11 is too high, the rubber pad 12 helps to alleviate the pressure, preventing direct damage to the sensor. Furthermore, the electronic scale housing 1, aluminum plate 13, and sensitive sensor 11 are designed with a thin sheet for the weight sensor 11. The aluminum plate 13 is mounted tightly against the top of the electronic scale housing 1, maintaining a small angle between them. This prevents the device from being used by someone using a magnet to attach it to the bottom of the aluminum plate 13, thus increasing its weight and preventing cheating.
[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
