Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electronic products, and in particular to an electronic scale anti-cheating structure and an electronic scale assembly. Background Art
[0002] The structure of the electronic platform scales currently on the market basically has no protective measures for the deformation holes of the electronic scale sensors, and the deformation holes are directly exposed to the outside.
[0003] The inventors have found that the electronic scales of the related art have at least the following disadvantages:
[0004] a. In the prior art, the deformation hole of the sensor is exposed to the external environment. Unscrupulous merchants can easily rub the deformation hole with a knife, etc., so that the strength of the strain gauge of the sensor is reduced and the deformation of the strain gauge is increased, thereby increasing the weight display on the electronic instrument to achieve the purpose of cheating.
[0005] b. In the prior art, the area where the sensor strain gauge is placed has no strong protection and is easily hit by hard objects or bitten by animals such as mice, causing the sensor to become inaccurate or fail. Utility Model Content
[0006] The purpose of the utility model includes providing an electronic scale anti-cheating structure and an electronic scale assembly, which can reduce the probability of electronic scale weighing cheating and improve the electronic scale weighing accuracy.

The upper cover blocks the upper part of the electronic sensor, and the lower cover blocks the lower part of the electronic scale sensor. In addition, the upper cover and the lower cover are connected, and the limiting protrusion on the lower cover is inserted into the fixing hole of the electronic scale sensor. In this way, the upper cover, the lower cover, and the electronic scale sensor form a whole. By blocking the electronic scale sensor with the upper cover and the lower cover, the strain gauge cannot be directly damaged by the deformation hole in the thickness direction of the electronic scale. At the same time, due to the design of the anti-cheating seal, it is impossible to open the upper cover and the lower cover without destroying the anti-cheating seal. When the anti-cheating seal is destroyed, it is possible to know whether the electronic scale has been adjusted in a cheating manner, and the anti-cheating effect is good.

DETAILED DESCRIPTION
[0039] In the existing technology, the electronic scale sensor 003 is installed between the load-bearing frame and the base 001. The load-bearing frame is a frame structure with a hollow area. The deformation position of the strain gauge of the electronic scale sensor 003 is exposed in the hollow area. Unscrupulous vendors use tools such as knives to destroy the strain gauge from the hollow area, causing the strain gauge strength to decrease and the deformation to increase, resulting in the weighing result being greater than the actual weight of the item.
[0040] In view of this, the designer provides an anti-cheating structure for electronic scales, which can effectively prevent merchants from cheating and improve the weighing accuracy of electronic scales.
[0041] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.
[0045] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.
[0046] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.
[0047] Please combine Figure 1-Figure 2 The present embodiment provides an anti-cheating structure for an electronic scale, which includes an upper cover 100, a lower cover 200, and an anti-cheating seal 300. The upper cover 100 is connected to the lower cover 200, and the two cooperate to define a channel for accommodating the electronic scale sensor 003. A limiting boss 210 is provided on the lower cover 200, and the limiting boss 210 extends into the channel. The limiting boss 210 is used to be inserted into the fixing hole 031 of the electronic scale sensor 003; the anti-cheating seal 300 is connected to both the upper cover 100 and the lower cover 200, and the upper cover 100 and the lower cover 200 are separated only when the anti-cheating seal 300 is destroyed.
[0048] As described above, the anti-cheating structure of the electronic scale provided in this embodiment is used as follows:
[0049] Please combine Figure 1 The electronic scale anti-cheating structure is used in conjunction with the electronic scale sensor 003. The electronic scale sensor 003 is inserted into the channel formed by the upper cover 100 and the lower cover 200. The electronic scale sensor 003 is roughly in the shape of a long strip, and the length direction of the electronic scale sensor 003 is consistent with the direction of the channel. During assembly, the lower cover 200 can be installed below the electronic scale sensor 003 first, and the time limit boss 210 is inserted into the fixing hole 031 on the electronic scale sensor 003. The upper cover 100 is installed above the electronic scale sensor 003 and is connected to the lower cover 200. The upper cover 100 blocks the upper part of the electronic sensor, and the lower cover 200 blocks the lower part of the electronic scale sensor 003. It should be understood that the upper cover 100 and the lower cover 200 are connected, and the limiting boss 210 on the lower cover 200 is inserted into the fixing hole 031 of the electronic scale sensor 003. In this way, the upper cover 100, the lower cover 200, and the electronic scale sensor 003 form a whole. By shielding the electronic scale sensor 003 with the upper cover 100 and the lower cover 200, the strain gauge cannot be directly damaged through the deformation hole in the thickness direction of the electronic scale. At the same time, due to the design of the anti-cheating seal 300, it is impossible to open the upper cover 100 and the lower cover 200 without destroying the anti-cheating seal 300. Once the anti-cheating seal 300 is destroyed, it is possible to know whether the electronic scale has been adjusted in a cheating manner, which is effective in preventing cheating. Moreover, because the upper cover 100 and the lower cover 200 shield the electronic scale sensor 003, most of the electronic scale sensor 003 is not directly exposed to the external environment, is not easily damaged by collisions, and has a long service life.
[0050] The following embodiments illustrate the details of the anti-cheating structure of the electronic scale provided in this application by way of examples.
[0051] Please combine Figure 1-Figure 2 In this embodiment, the upper cover 100 and the lower cover 200 are optionally fixedly connected by fasteners 400. After the upper cover 100 and the lower cover 200 are installed in place, they are locked with the fasteners 400, which is easy to operate and the position of the upper cover 100 and the lower cover 200 is firm and not easy to loosen.
[0052] It should be understood that the fastener 400 may be a bolt, a screw, an anchor, a pin, etc. For example, in this embodiment, the fastener 400 is set as a screw for illustration.
[0053] Optionally, the upper cover 100 is a flat metal plate, and the lower cover 200 is a folded metal plate. The lower cover 200 has a receiving groove 220 and is provided with two outward-turned folded edges 230 spaced apart along the width of the receiving groove 220. Both outward-turned folded edges 230 are attached to the upper cover 100 and are fixedly connected to the upper cover 100 via fasteners 400. The limiting boss 210 is provided on the bottom wall of the receiving groove 220. The provision of the outward-turned folded edges 230 provides a mounting position for the fasteners 400, facilitating the use of the fasteners 400 to secure the upper and lower covers 100 and 200. Both outward-turned folded edges 230 are connected to the upper cover 100 via fasteners 400, providing multiple connection locations and a secure and reliable connection.
[0054] It should be noted that the upper cover 100 and the lower cover 200 are both made of metal or plastic, etc., and have high structural strength and are not easily damaged.
[0055] Optionally, a sleeve 240 is provided on the outward-turned folding edge 230, which protrudes in a direction away from the upper cover 100. The sleeve 240 is provided with a threaded hole, and the fastener 400 passes through the outward-turned folding edge 230 and is inserted into the sleeve 240. At least one sleeve 240 can be provided on each outward-turned folding edge 230. In this way, each outward-turned folding edge 230 can correspond to at least one fastener 400. The fastener 400 is used to fix the upper cover 100 and the lower cover 200 together. The fastener 400 is directly threaded into the sleeve 240, which makes installation convenient and reliable.
[0056] Optionally, a notch 250 is provided on the side wall of the lower cover 200 forming the accommodating groove 220. The notch 250 design can reduce the material required for the lower cover 200 and reduce the processing and manufacturing cost.
[0057] Please combine Figure 1-Figure 2 Optionally, a first mounting hole 101 and a second mounting hole 102 are provided on the upper cover 100, and a third mounting hole 231 and a fourth mounting hole 232 are provided on the outward folding edge 230. The first mounting hole 101 is connected to the third mounting hole 231, and the second mounting hole 102 is connected to the fourth mounting hole 232. The anti-cheating seal 300 passes through the first mounting hole 101, the third mounting hole 231, the fourth mounting hole 232 and the second mounting hole 102 in sequence. It should be understood that the first mounting hole 101, the second mounting hole 102, the third mounting hole 231 and the fourth mounting hole 232 cooperate to position an anti-cheating seal 300. When the number of anti-cheating seals 300 is multiple, it is sufficient to adaptively set the corresponding number of first mounting holes 101, second mounting holes 102, third mounting holes 231 and fourth mounting holes 232.
[0058] To avoid redundant description, an anti-cheating seal 300 is taken as an example for detailed description.
[0059] Please combine Figure 1-Figure 2 Optionally, the anti-cheating seal 300 includes a sealing strip 310 and a sealing block 320. The sealing strip 310 sequentially passes through the first mounting hole 101, the third mounting hole 231, the fourth mounting hole 232, and the second mounting hole 102, and the sealing block 320 is simultaneously fixed to the portion of the sealing strip 310 that passes through the first mounting hole 101 and the second mounting hole 102. In other words, the sealing strip 310 is configured as a U-shaped piece, with both ends of the sealing strip 310 passing through the lower cover 200 at the locations of the third mounting hole 231 and the fourth mounting hole 232 and passing through the upper cover 100 at the first mounting hole 101 and the second mounting hole 102. The sealing block 320 is then fixed to the sealing strip 310, which is convenient for operation.
[0060] It should be understood that the sealing strip 310 and the sealing block 320 are both metal parts, and the two can be welded and fixed, so that the combination is firm and the damaged traces are obvious, which is conducive to identification. In addition, the two can also be fixedly connected by other means such as lead sealing.
[0061] The anti-cheating structure of the electronic scale provided in this embodiment is provided with an anti-cheating seal 300. Only when the anti-cheating seal 300 is broken can the upper cover 100 and the lower cover 200 be opened, thereby exposing the deformed portion of the strain gauge of the electronic scale sensor 003. After the anti-cheating seal 300 is broken, it is easy to identify, thereby facilitating obtaining information on whether the electronic scale has been manually adjusted, and achieving a good anti-cheating effect.
[0062] Please combine Figure 3-Figure 4 This embodiment also provides an electronic scale assembly, comprising a base 001, a support frame 002, an electronic scale sensor 003, and the aforementioned anti-cheating structure for the electronic scale sensor 003. The base 001 and support frame 002 cooperate to clamp the electronic scale sensor 003. The electronic scale sensor 003 and the base 001 can be fixedly connected by bolts, and the electronic scale sensor 003 and the support frame 002 can also be fixedly connected by bolts. In addition, the upper cover 100 can be welded to the support frame 002, so that the upper cover 100, support frame 002, electronic scale sensor 003, lower cover 200, and anti-cheating seal 300 form a single unit, increasing the difficulty of cheating.
[0063] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
