Technical Field

[0001] The utility model relates to the technical field of metrology, in particular to a weighing tray for metrological self-certification. Background Art

[0002] In life, digital indicating scales are a relatively common measuring instrument. However, during the metrological process of current digital indicating scales, cheating often occurs, and this cheating behavior will damage the reputation of merchants and the interests of consumers. Eliminating "short weights and measures" is the common expectation of the majority of consumers at present and is also what the vast majority of honest merchants hope to prove to consumers.

[0003] In the utility model patent CN211347052U, an electronic weighing tray is designed, which can make the connection between the tray and the supporting chassis more stable, avoid the shaking of the tray when bearing weight, and can weigh some items with a volume larger than the tray, improving the practicability of the tray. However, in this utility model, the weight of the electronic weighing tray is unknown. The tray involves many components, and the components can be disassembled and replaced, resulting in the total weight of the tray being adjustable. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a weighing tray for metrological self-certification to solve the problems that the weight of the tray of the current digital indicating scale is not clearly informed and the total weight changes because the tray is composed of multiple components and can be disassembled.

[0005] To solve the above problems, the utility model provides a weighing tray for metrological self-certification, which includes a tray body, a front bending part and a rear bending part. The tray body, the front bending part and the rear bending part are formed by bending a flat plate. The front bending part is located on the front side of the tray body, and the rear bending part is located on the rear side of the tray body.

[0006] A self-weight identification area is arranged on the front side surface of the front bending part.

[0007] Further, the included angle between the surface of the front bending part facing the tray body and the tray body does not exceed 80°. The surface of the tray body with an included angle not exceeding 80° with the front bending part is the upper bottom surface of the tray, and the surface of the tray body opposite to the upper bottom surface of the tray is the lower bottom surface of the tray.

[0008] Further, a plurality of anti-slip strips are arranged on the lower bottom surface of the tray, and the anti-slip strips and the tray body are integrally designed.

[0009] Further, the surface of the anti-slip strip is non-smooth.

[0010] Further, there are bottom through holes on the anti-slip strip for draining water on the upper bottom surface of the tray to the outside of the tray body.

[0011] Further, on one side of the tray body opposite to the front bending portion is a rear bending portion.

[0012] Further, a code scanning verification area is arranged on the front surface of the front bending portion.

[0013] Further, the self-weight identification area identifies the weight of the weighing tray for self-verification by weighing.

[0014] The beneficial effects of a weighing tray for self-verification by weighing provided by the present utility model are as follows: Compared with the prior art, due to the design of the self-weight identification area, the weight recorded in the self-weight identification area is the weight of the weighing tray for self-verification by weighing itself, and the weight of the tray body is constant and known. Since no other detachable components are provided on the tray body, the weight of the tray body will not change during use. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 2 FIG. is a bottom view schematic of a weighing tray for self-verification by weighing. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] In order to better understand the purpose, structure and function of the present utility model, the following further describes in detail a weighing tray for self-verification by weighing according to the present utility model in conjunction with the attached Figures 1 to 2 , and makes a further detailed description of a weighing tray for self-verification by weighing according to the present utility model.

[0018] Such as Figure 1As shown in the figure, a weighing tray for metrological self-certification according to an embodiment of the present utility model includes a tray body 1, a front bending part 2, and a rear bending part 4. The tray body 1, the front bending part 2, and the rear bending part 4 are formed by bending a flat plate. The front bending part 2 is located on the front side of the tray body 1, and the rear bending part 4 is located on the rear side of the tray body 1. The weighing tray for metrological self-certification is designed to have a constant weight, such as 500 grams or 1000 grams. During use, the tray body 1 is placed on a digital indicating scale, and then the item to be weighed is placed on the tray body 1, so as to realize weighing on the digital indicating scale. Since the weighing tray for metrological self-certification has a constant and clearly marked weight, and there are no detachable additional components, during the actual weighing process, when only the tray body 1 is placed on the digital indicating scale, the digital indicating scale will display a value, which is the actual weight of the weighing tray for metrological self-certification weighed by this digital indicating scale. If this value is the same as the designed weight of the weighing tray for metrological self-certification, it means that this digital indicating scale is normal and there is no cheating behavior. Then, place the item to be weighed for weighing, and subtract the weight of the weighing tray for metrological self-certification from the total weight weighed again, which is the weight of the item to be weighed. It is also possible to zero first and then place the item to be weighed, and the obtained value is the weight of the item to be weighed. During the rectification weighing process, the weighing tray and the digital indicating scale are used in combination, and the accuracy of the scale can be verified immediately by itself, playing the role of metrological self-certification. It is difficult for the existing cheating means of digital indicating scales to cheat when the additional mass of the weighing tray for metrological self-certification is displayed accurately, so the accuracy of the weight of the item to be weighed is ensured.

[0019] In the present utility model, a self-weight identification area 21 and a code scanning verification area 22 are provided on the front bending part 2. During use, the weight information of the weighing tray for metrological self-certification can be marked on the self-weight identification area 21, so that the weight data of the weighing tray for metrological self-certification can be accurately used during use. In addition to marking the weight data, production information such as the manufacturer and production date can also be marked on the self-weight identification area 21. A two-dimensional code can be set on the code scanning verification area 22, and unified traceability supervision can be carried out by scanning the two-dimensional code during use.

[0020] The front bending part 2 also has the function of a handle. When it is necessary to place and remove the weighing tray for metrological self-certification, the weighing tray for metrological self-certification can be placed and removed by holding the area of the front bending part 2.

[0021] In order to be able to see the information on the front bending part 2 and be able to hold the front bending part 2 well, the included angle between the side facing the tray body 1 and the tray body 1 is designed to be no more than 80°. At the same time, the side of the tray body 1 with an included angle of no more than 80° with the front bending part 2 is defined as the upper bottom surface 11 of the tray, and the side of the tray body 1 opposite to the upper bottom surface 11 of the tray is defined as the lower bottom surface 12 of the tray.

[0022] As Figure 1 and Figure 2 shown, understandably, a number of anti-slip strips 3 are provided on the lower bottom surface 12 of the tray. The anti-slip strips 3 and the tray body 1 are integrally designed. When producing the weighing tray for self-certification, through stamping technology, a number of anti-slip strips 3 are produced on the lower bottom surface 12 of the tray. Using stamping technology only changes the structure of the tray body 1 and does not change the weight of the tray body 1. During use, these anti-slip strips 3 come into contact with the digital indicating scale, which can play a role in anti-slip and limiting for the tray body 1, and prevent the tray body 1 from shifting with the digital indicating scale and causing the item to be weighed to fall. To further improve the anti-slip effect of the anti-slip strips 3, the surface of the anti-slip strips 3 is designed as a non-smooth surface, such as painting or knocking out depressions during the production process.

[0023] During the use process, there may be water residue on the item to be weighed. A bottom through-hole 31 is also designed on the anti-slip strip 3, so that the water on the upper surface 11 of the tray can be discharged outside the tray body 1 through the bottom through-hole 31, making the weighing more accurate.

[0024] In the present utility model, a rear bending part 4 is also provided on one side of the tray body 1 opposite to the front bending part 2. The rear bending part 4 and the tray body 1 are integrally designed. During the weighing process, the rear bending part 4 can prevent the item to be weighed on the tray body 1 from slipping out.

[0025] And these front bending parts 2, anti-slip strips 3 and rear bending parts 4 are also designed before leaving the factory and form an inseparable whole with the tray body 1. During the use process, the weight of the weighing tray for self-certification does not change, thus ensuring the accuracy of weighing.

[0026] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the protection scope of the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
