DETAILED DESCRIPTION
[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more specific definition of the protection scope of the present invention. The directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "top", "bottom", etc., are only for reference to the directions of the attached drawings. Therefore, the directional terms used are used to illustrate and understand the present invention, rather than to limit the present invention.
[0022] like Figure 1-3 A medical weight scale convenient for the elderly to use is shown, comprising a base 1 and a weighing plate 4 arranged on the base 1, a display screen 2, and a servo motor 9. The display screen 2 is used for reading the weighing plate 4. A hydraulic cylinder 3 is arranged at each of the four corners of the bottom end of the weighing plate 4. The weighing plate 4 is fixed to the base 1 through the hydraulic cylinder 3. A guide seat 8 is arranged at the bottom end of the weighing plate 4. The guide seat 8 is fixed to the base 1, and the guide seat 8 is slidably matched with the weighing plate 4. The weighing plate 4 is driven to rise by the hydraulic cylinder 3, and the guide seat 8 ensures its stability when rising.
[0023] A limiting mechanism for wheelchair positioning is installed on the upper surface of the scale plate 4. The scale plate 4 is lifted by the hydraulic cylinder 3, and the wheelchair and the user are lifted together for weighing. The limiting mechanism includes a positioning bin 11 fixed on the scale plate 4. Support plates 12 are inserted on both sides of the positioning bin 11. The support plates 12 are slidably connected to the positioning bin 11, and arc grooves are provided on the upper surface of the outer ends of the support plates 12. The support plates 12 on both sides are pulled to adapt to the width of the wheelchair, and the arc grooves are provided to support and lift the cross beams on both sides of the wheelchair;
[0024] Specifically, a slot is provided on the upper surface of the positioning bin 11, and a support plate 13 is provided inside the slot. One end of the support plate 13 is rotatably installed in the slot through a rotating shaft, and a clamping slot 14 is provided at the other end of the support plate 13. The clamping slot 14 is clamped on the rear beam of the wheelchair to improve the stability of the support plate 13 after support. A support inclined surface 15 is provided at one end of the slot near the rotation connection of the support plate 13. The support angle of the support plate 13 is limited by the support inclined surface 15, so that the support plate 13 can stably support the rear beam of the wheelchair.
[0025] Furthermore, handrails 10 are provided on both sides of the base 1, a slope 7 is provided at one end of the base 1, and two guide grooves 5 are provided on the upper surface of the base 1, the two guide grooves 5 are respectively located on both sides of the above-mentioned scale plate 4, and a conveyor belt 6 is provided inside the guide groove 5, the width of the conveyor belt 6 is greater than the width of the wheelchair wheel, and anti-sliding blocks are linearly arranged on the conveyor belt 6, and the conveyor belt 6 is driven by a servo motor 9 arranged on the base 1.
[0026] In this embodiment, when using the device, the user directly pushes the wheelchair to make it located above the scale plate 4. After the wheelchair wheels are located in the guide grooves 5, the conveyor belt 6 can drive the wheelchair to automatically move above the scale plate 4, thereby reducing the user's work intensity.
[0027] By pulling the support plate 13 to make it fit with the cross beams on both sides of the wheelchair, the hydraulic cylinder 3 is opened, and the hydraulic cylinder 3 drives the scale plate 4 to rise, and the wheelchair and the patient are lifted up at the same time for weighing;
[0028] During the weighing process, the support plate 13 is rotated and abutted against the support inclined surface 15, and the slot 14 on the support plate 13 abuts against the rear crossbeam of the wheelchair, so that the wheelchair can be supported during weighing to reduce the impact of the wheelchair tilting backward;
[0029] After weighing the entire device, the patient's weight can be obtained by removing the weight of the wheelchair, and the specifications of the wheelchair are of uniform standard.
[0030] It should be noted that the parts not covered in the present invention are the same as the prior art or can be implemented by the prior art; the various drives in the present invention can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, motors, etc. in combination with connecting rods, guide rods, etc., and are not limited to the description in the specification and the structures in the drawings.
