[0035] In the description of the embodiment, the terms "upper", "lower", "right", "left", "horizontal", "vertical", and "radial" are terms of reference and orientation only and are made only to facilitate description and simplify the operation, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the utility model. In addition, the terms "first", "second" are only used to distinguish in the description, and have no special meaning.

[0036] The embodiment discloses a carpet scale, as shown in the figure, which comprises a scale disc 10, a bottom shell 20 and an elastic structure 30. Figures 1-4 The bottom end of the scale disc 10 is provided with a plurality of sensing elements 40; the bottom shell 20 is arranged at the bottom of the scale disc 10, and a control panel is arranged in the bottom shell 20; the sensing elements 40 are in communication connection with the control panel; the elastic structure 30 is arranged between the scale disc 10 and the bottom shell 20 and simultaneously connects the scale disc 10 and the bottom shell 20; the elastic structure 30 comprises a limiting space 33, and a movable part 41 of the sensing element 40 is arranged in the limiting space 33; when the carpet scale is lifted in the vertical direction, the movable part 41 can abut against the inner wall of the limiting space 33.

[0037] In the process of weighing, the scale pan 10 is moved and pressed by the gravity of the weight, the sensing member 40 generates deformation in the limiting space 33 and generates an electrical signal which is transmitted to the control panel, and finally the control panel processes the signal and displays the weighing assembly through the display panel or voice broadcast and the like. In this process, the elastic structure 30 is deformed after the scale pan 10 is stressed, so that the relative movement between the scale pan 10 and the bottom shell 20 occurs, thereby ensuring the accuracy of the weighing value. When the scale pan 10 needs to be extracted through the entire carpet scale, the scale pan 10 will give the bottom shell 20 an upward pulling force through the elastic structure 30, and at the same time the bottom shell 20 will pull the elastic structure 30 downward under the action of its own gravity. At this time, since the movable part 41 of the sensing member 40 is located in the limiting space 33 and can abut against the inner wall of the limiting space 33, the elastic structure 30 will simultaneously receive a supporting force upward from the sensing member 40. At this time, the risk of breaking the elastic structure 30 due to the excessive weight of the bottom shell 20 or the too fast action of pulling the scale pan 10 can be effectively reduced, thereby improving the service life and use experience of the carpet scale.

[0038] Specifically, as shown in Figures 2-4 , the elastic structure 30 includes a limiting member 31 and an elastic arm 32, the limiting member 31 is arranged at one end of the elastic arm 32, the other end of the elastic arm 32 is connected to the bottom of the scale pan 10, the limiting member 31 is connected to the bottom shell 20, and the limiting space 33 is arranged in the limiting member 31. In this structure, the two ends of the elastic structure 30 are respectively connected to the scale pan 10 and the bottom shell 20, and the limiting space 33 is arranged at the end connected to the bottom shell 20. Therefore, when the scale pan 10 is pulled upward, the gravity of the bottom shell 20 will give the limiting member 31 a downward pulling force, and at the same time the movable part 41 of the sensing member 40 can give the elastic structure 30 an upward pulling force from the inside of the limiting space 33, which can offset part of the gravity of the bottom shell 20, thereby effectively reducing the risk of breaking the elastic arm 32 and improving the service life.

[0039] In addition, in order to simplify the overall structure, as shown in Figure 4 , the limiting member 31 includes a first limiting plate 311 and a second limiting plate 312 which are connected to each other, the side of the second limiting plate 312 away from the first limiting plate 311 is connected to the elastic arm 32, and the movable part 41 can abut against the first limiting plate 311 when the carpet scale is extracted in the vertical direction. In this structure, the inner wall of the second limiting plate 312 can laterally limit the sensing member 40, and the movable part 41 of the sensing member 40 can abut against the bottom end of the first limiting plate 311 when the scale pan 10 is lifted, thereby playing a supporting role for the elastic structure 30. Not only is the structure simple, but also the limiting effect is good, and the use experience is improved.

[0040] In addition, as shown in Figure 4As shown, the limiting piece 31 further comprises a third limiting plate 313 connected to the other end of the second limiting plate 312, and the first limiting plate 311, the second limiting plate 312 and the third limiting plate 313 enclose the limiting space 33. Such a setting not only simplifies the composition structure of the limiting space 33, but also the first limiting plate 311 and the third limiting plate 313 can jointly act and limit the movement space of the movable part 41 in the vertical direction, thereby ensuring that the deformation of the sensing piece 40 does not exceed the preset range, thereby ensuring good use effect, and also improving the service life of the structure.

[0041] In addition, as shown in Figure 4 As shown, the first limiting plate 311, the second limiting plate 312 and the third limiting plate 313 are all arc-shaped plates. The structure of the arc-shaped plate can make the limiting space 33 better match the movable part 41 of the sensing piece 40, and also facilitate the movable part 41 to extend into the limiting space 33 from the arc-shaped opening, facilitating use; at the same time, the arc-shaped plate can further improve the space utilization, while saving the internal space of the carpet scale and ensuring the structural strength.

[0042] For easy installation, as shown in Figure 3 and Figure 4 As shown, the side of the second limiting plate 312 away from the first limiting plate 311 and the third limiting plate 313 is provided with a plurality of mounting portions 314, which can be detachably connected with the bottom shell 20. In addition, the end of the elastic arm 32 away from the limiting piece 31 is provided with a mounting plate 34, which can be detachably connected with the scale disc 10. Through the mounting portion 314 and the mounting plate 34, the limiting piece 31 and the elastic arm 32 can be respectively detachably connected with the bottom shell 20 and the scale disc 10, thereby facilitating subsequent maintenance and replacement.

[0043] It should be noted that, as shown in Figure 4 The mounting portion 314 and the mounting plate 34 are both provided with a plurality of mounting holes 35, and the locking piece 50 can pass through the mounting hole 35 to be detachably connected with the scale disc 10 and the bottom shell 20, which is simple and convenient to operate. In addition, the locking piece 50 is a bolt. The structure of the bolt is simple and low in price, which is convenient for batch processing and helps to reduce manufacturing cost.

[0044] In order to further improve the structural strength, as shown in Figure 4 The elastic arms 32 are spaced apart. Such a setting can further improve the overall use strength of the elastic structure 30, thereby effectively avoiding the breakage of the elastic arm 32 when lifting the scale disc 10, and improving the service life.

[0045] In addition, it is worth noting that the limiting piece 31 and the elastic arm 32 are an integral structure. Such a setting can reduce the processing difficulty and improve the processing efficiency, thereby effectively reducing the manufacturing cost.

[0046] As Figure 2 shown, the plurality of sensing members 40 are arranged along the circumference of the scale pan 10, and the plurality of elastic structures 30 are correspondingly arranged. The plurality of sensing members 40 can improve the accuracy of measuring the weight of the weight, and the plurality of elastic structures 30 can ensure the uniformity of the force received by the elastic structures 30 when the scale pan 10 is lifted, thereby further avoiding the risk of a single elastic structure 30 being broken due to excessive force, and further improving the service life.

[0047] Further, in the present embodiment, the weighing range of the carpet scale is 0-280kg, and the weighing accuracy of the carpet scale is not less than 0.2kg. Such a structure can ensure that the carpet scale can be applied to people with large weights, while ensuring accurate weighing effect and improving user experience. Specifically, when the person or weight to be weighed is 0-100kg, the weighing accuracy of the carpet scale is ±0.1kg, and when the person or weight to be weighed is 100-280kg, the weighing accuracy of the carpet scale is ±0.2kg, thereby ensuring the accuracy of the weighing result.
