Description

Technical Field

[0001] This utility model relates to the field of calibration weight technology, and more specifically to a combined calibration weight for inspecting the net content of packaged goods. Background Technology

[0002] Net content inspection of packaged goods refers to the process of measuring and verifying the net content labeled on pre-packaged goods (such as food, daily chemical products, etc.) to ensure that the actual weight or volume of its contents meets the standards declared on the label. When inspecting the net content of packaged goods, a combination calibration weight is required. The combination calibration weight is a modular high-precision measuring tool, which consists of multiple independent weight units that can be separated or combined. It is mainly used to calibrate weighing equipment such as balances and electronic scales to ensure the accuracy of its measurement results.

[0003] However, despite the widespread use of combined calibration weights in the field of metrology, some limitations still exist.

[0004] Especially when combining weights, it relies heavily on the professional operation of personnel. Improper combination (such as not tightening completely) may introduce weighing deviation. In addition, most weights are combined using threaded or stacked methods. Threaded connections are slightly cumbersome to operate, while stacked combinations are convenient but need to be prevented from tipping over. Therefore, there is great inconvenience in actual use. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a special combination calibration weight for inspecting the net content of packaged goods, so as to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a special combination calibration weight for inspecting the net content of packaged goods, including a first calibration weight, a second calibration weight movably connected to the bottom of the first calibration weight, a combination inner groove at the bottom of both the first and second calibration weights, and a combination protrusion at the top of both the first and second calibration weights. The combination inner groove and the combination protrusion are mutually engaged. The first and second calibration weights have the same overall structure and shape. The combination protrusion and combination inner groove facilitate quick and accurate positioning and connection of the first and second calibration weights through the combination slot and rectangular limiting slider when they are combined, reducing the professionalism of their combination and avoiding weighing deviations due to improper operation.

[0007] Furthermore, the first calibration weight has a sleeve cavity in the middle of the combined inner groove, a combined slot is formed on one side of the surface of the combined inner groove, and a limiting inner groove is formed near the inner side of the first calibration weight. The limiting inner groove helps to restrict the combined protrusion of the docking assembly, thus preventing the assembly from being unstable and tipping over.

[0008] Furthermore, a cylindrical sleeve is provided at the top of the combined protrusion, and a rectangular limiting slider is provided on one side of the surface of the combined protrusion. The combined protrusion facilitates riveting with the combined inner groove and completes the rapid combination connection between the weights through rotation.

[0009] Furthermore, the rectangular limiting slider with the combined protrusion has the same length and width as the combined slot, and the diameter and height of the cylindrical sleeve have the same diameter and depth as the inner cavity. By using the inner cavity, it is beneficial to quickly complete the combined positioning of the weights.

[0010] Furthermore, the height of the rectangular limiting slider is the same as the height of the limiting inner groove. By having the height of the rectangular limiting slider be the same as the height of the limiting inner groove, it is beneficial for the rectangular limiting slider to slide inside the limiting inner groove, thereby limiting the combined weights and preventing them from tipping over.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model, by providing a combination protrusion and a combination inner groove, facilitates quick and accurate positioning and connection of the first and second calibration weights through the combination slot and rectangular limiting slider, reducing the professionalism of the combination and avoiding weighing deviations due to improper operation.

[0013] 2. This utility model, by providing combined protrusions and combined inner grooves, facilitates quick positioning and connection via mortise and tenon structure, reduces the complexity of its assembly operation steps, and avoids tipping during assembly, thereby improving its convenience in actual use.

[0019] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The combined calibration weight for net content inspection of packaged goods involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Reference Figures 1-4 As shown, this utility model provides a special combination calibration weight for inspecting the net content of packaged goods, including a first calibration weight 1, a second calibration weight 2 movably connected to the bottom of the first calibration weight 1, a combination inner groove 3 at the bottom of both the first calibration weight 1 and the second calibration weight 2, and a combination protrusion 4 at the top of both the first calibration weight 1 and the combination inner groove 3 and the combination protrusion 4 are mutually engaged. The first calibration weight 1 and the second calibration weight 2 have the same overall structure and shape. Through the combination protrusion 4 and the combination inner groove 3, it is convenient to quickly and accurately position and connect the first calibration weight 1 and the second calibration weight through the combination slot 301 and the rectangular limiting slider when combining them, reducing the professionalism of their combination and avoiding weighing deviation due to improper operation.

[0021] The first calibration weight 1 has a sleeve cavity 101 in the middle of the combined inner groove 3, and a combined slot 301 is provided on one side of the surface of the combined inner groove 3. A limiting inner groove 302 is provided on the inner side of the combined inner groove 3 near the first calibration weight 1. The limiting inner groove 302 helps to limit the position of the combined protrusion 4 of the docking assembly, so as to prevent the assembly from being unstable and tipping over.

[0022] The top of the combined protrusion 4 is provided with a cylindrical sleeve 402, and a rectangular limiting slider 401 is provided on one side of the surface of the combined protrusion 4. The combined protrusion 4 facilitates the riveting of the combined inner groove 3 and the rapid combination connection between the weights through rotation.

[0023] Among them, the rectangular limiting slider 401 of the combined protrusion 4 has the same length and width as the combined slot 301, and the diameter and height of the cylindrical sleeve 402 are the same as the diameter and depth of the sleeve inner cavity 101. By using the sleeve inner cavity 101, it is easy to quickly complete the combined positioning between weights.

[0024] The rectangular limiting slider 401 has the same height as the limiting inner groove 302. This allows the rectangular limiting slider 401 to slide inside the limiting inner groove 302, thereby limiting the combined weights and preventing them from tipping over.

[0025] The working principle of this utility model:

[0026] First, when combining the first calibration weight 1 and the second calibration weight 2, pinch the cylindrical sleeve 402 so that the cylindrical sleeve 402 moves the first calibration weight 1 to the top position of the second calibration weight 2. Then, align the inner cavity 101 at the bottom of the first calibration weight 1 with the cylindrical sleeve 402 at the top of the second calibration weight 2. Next, rotate the first calibration weight 1 according to the position of the rectangular limiting slider 401 at the top of the second calibration weight 2 so that the combination slot 301 and the rectangular limiting slider 401 are aligned. Then, slowly move the first calibration weight 1 closer to the top position of the second calibration weight 2 so that the rectangular limiting slider... When block 401 enters the combination slot 301, the cylindrical sleeve 402 enters the sleeve inner cavity 101. Then, the first calibration weight 1 is rotated, causing the limiting inner groove 302 to rotate at the surface of the combination protrusion 4. At this time, the combination slot 301 moves away from the rectangular limiting slider 401. At this time, the first calibration weight 1 and the second calibration weight 2 are combined and connected. Then, when it is necessary to separate the first calibration weight 1 and the second calibration weight 2, the first calibration weight 1 is rotated again and lifted upward. Then, when the combination slot 301 rotates to the position of the rectangular limiting slider 401, the first calibration weight 1 and the second calibration weight 2 are separated.
