[0030] Example 1, please refer to Figure 1 :

[0031] A weighing chair suitable for elderly patients, which includes: a support seat, a chair board body, an electronic weighing board 300, a display panel 500, and an operation panel 400. In this example,

[0032] The support seat adopts an electric lifting pile 100, and the top of the electric lifting pile 100 is provided with an installation surface;

[0033] The chair board body includes: a horizontal chair board 210, a backrest board 220, a left armrest 230, and a right armrest 230. The horizontal chair board 210 extends in the horizontal direction, and armrests 230 are symmetrically and fixedly installed on the left and right sides of the horizontal chair board 210; the backrest board 220 is fixedly installed on the rear side of the horizontal chair board 210, the backrest board 220;

[0034] The electronic weighing board 300 specifically adopts an electronic coil weighing board. The lower side of its board body is fixedly installed on the installation surface; the upper side of its board body is fixedly installed and integrated with the lower side of the board body of the horizontal chair board 210; the electronic weighing board 300 is used to obtain a weighing value when in the power-on state. In this example, the electronic weighing board 300 specifically adopts an electronic coil weighing board. The electronic coil weighing board is a mature existing structure, which is internally provided with a metal shrapnel and a coil structure. When weighing, the metal shrapnel deforms, thereby changing the resistance value of the coil. This change in resistance value is proportional to the weight of the object being weighed. By measuring this change, the weighing value can be obtained.

[0035] The operation panel 400 is fixedly installed on the side of the backrest board 220 facing away from the board body of the horizontal chair board 210; a power supply battery is integrated in the operation panel 400; the power supply battery is electrically connected to the electronic weighing board 300 and is used to supply power to the electronic weighing board 300; a control switch 410 is also provided on the board surface of the operation panel 400, and the control switch 410 is configured to adjust the on / off state of the power supply battery supplying power to the electronic weighing board 300. The display panel 500 is signal-connected to the electronic weighing board 300 through a signal line (not shown in the figure) and is used to display in real time the weighing value obtained by the electronic weighing board 300. The display panel 500 and the operation panel 400 are integrally installed.

[0036] In practice, its working process is as follows:

[0037] Support the elderly patient to sit on the seat plate body, making the buttocks fit the horizontal seat plate 210, the back fit the backrest plate 220, and the hands be placed on the left armrest 230 and the right armrest 230 respectively, so as to keep the body of the elderly patient stable. At this time, the power supply battery is in a power-off state for supplying power to the electronic weighing plate 300. After the elderly patient sits on the seat plate body, start the electric lifting pile 100 to lift the seat plate body upward, so that the elderly patient can enter the weighing state with both feet suspended without exerting force. At this time, operate the control switch 410 on the operation panel 400 to make the power supply battery be in a power-on state for supplying power to the electronic weighing plate 300. Since the weight of the seat plate body is certain, the weighing zero position of the electronic weighing plate 300 can be adjusted in advance so that the output weighing value corresponds to the weight value of the elderly patient. This weighing value is displayed in real time through the display panel 500. That is, the convenient and fast weighing operation of the elderly patient in the sitting posture state is completed.

[0038] For Embodiment 2, please refer to Figures 1 - 3 :

[0039] Compared with Embodiment 1, Embodiment 2 further includes a leg support plate 610. Specifically:

[0040] A rectangular groove is provided on the lower side of the plate body of the horizontal seat plate 210, and this rectangular groove is close to the position on the front side of the horizontal seat plate 210. A rotating shaft is installed in this rectangular groove. The plate body shape of the leg support plate 610 is adapted to the rectangular groove. The rear side of the plate body of the leg support plate 610 is connected to the rotating shaft and reciprocates between a horizontal position and a vertical position as the rotating shaft rotates. When it moves to the horizontal position, at least part of the plate body of the leg support plate 610 extends out of the front side of the horizontal seat plate 210 in the horizontal direction.

[0041] A mounting groove 211 is further provided on the lower side of the plate body of the horizontal chair plate 210. The mounting groove 211 extends towards the rotating shaft, and a clamping strip 212 is slidably mounted in the mounting groove 211. The clamping strip 212 is used to move along the extending direction of the mounting groove 211 to reach the limiting position / move back to the original position. And when the clamping strip 212 moves to the limiting position, it is used to support the lower side of the plate body of the leg support plate 610 that has moved to the horizontal position, so as to prevent the leg support plate 610 from flipping from the horizontal position to the vertical position. An opening groove 613 is provided on the front side of the plate body of the leg support plate 610, and an extension plate 620 is slidably mounted in the opening groove 613 (there are many connection methods between the two, such as further providing a slideway in the opening groove and providing a caliper on the extension plate to install the slider in the slideway. The above connection methods are all conventional technical means in the art, so they will not be elaborated in this article); A flip cover 611 is provided on one side of the opening groove 613, and a plug hole 612 matching the flip cover 611 is provided on the other side.

[0042] In practice, its working process is as follows:

[0043] After the elderly patient sits on the chair plate body, rotate the leg support plate 610 until the plate body extends horizontally, and place the legs of the elderly patient on the upper side of the plate body of the leg support plate 610 to prevent the feet of the elderly patient from hanging to the ground due to physical problems or compliance problems during the weighing process, which may affect the reading stability. At the same time, as the legs of the elderly patient are lifted onto the leg support plate 610 and their back naturally leans on the backrest plate 220, the physical stability of the elderly patient during the weighing process is improved, and the sense of security of the elderly patient is enhanced. For elderly patients of different body types, in practice, the flip cover 611 can be opened, and the extension plate 620 can be pulled out from the leg support plate 610 to increase the support area for the legs of the elderly patient, thereby improving the adaptability to elderly patients of different body types and reducing the design models of the leg support plate 610.
