Description

Technical Field

[0001] This utility model relates to the field of waist circumference measuring instruments, and more specifically, to a dynamic waist circumference measuring instrument. Background Technology

[0002] Obesity is a condition caused by excessive accumulation of body fat, especially triglycerides. It is usually due to excessive food intake or changes in metabolism, leading to excessive weight gain and pathophysiological changes in the body. During weight loss, it is necessary to measure waist circumference frequently to monitor progress.

[0003] A search revealed that utility model patent CN217827850U ​​discloses a human waist and hip circumference measuring instrument, including a vertically arranged first fixing tube. An elastic fixing strip is positioned above the first fixing tube, with scale lines for measurement on its surface. One end of the fixing strip is fixed to the top of the first fixing tube, and the other end passes through the first fixing tube and is located below it. The fixing strip above the first fixing tube has a ring-shaped structure. This design allows the user to hold the first fixing tube and then measure the waist and hip circumference of the subject using the ring-shaped fixing strip, avoiding contact between the measurer's hands and the subject's waist and hips, thus preventing embarrassment for both parties. It also prevents the spread of germs after contact, ensuring the health of both parties. The instrument is simple in structure and easy to operate. However, the above patent still has the following shortcomings: when repeatedly measuring the same weight loss user, it is not easy to ensure that the measurement position is the same each time, which affects the accuracy of the measurement and makes it difficult to control the specific situation of the weight loss user. In addition, it is not easy to remember and store the data of each measurement of the weight loss user, making it difficult to compare the waist circumference data of the weight loss user. Therefore, we have proposed a dynamic waist circumference measuring instrument. Utility Model Content

[0024] Example:

[0025] Please see Figure 1-4 A dynamic waist circumference measuring instrument includes a base plate 1, a vertical plate 2 fixedly connected to the top surface of the base plate 1, a lifting groove 3 and a mounting groove 4 on the vertical plate 2, a lead screw 5 rotatably connected to the inner cavity of the lifting groove 3, a first motor 6 fixedly installed in the inner cavity of the mounting groove 4, the output shaft of the first motor 6 being connected to the top end of the lead screw 5, a lifting seat 8 threaded onto the outer side of the lead screw 5, a waist circumference measuring mechanism 9 provided on the front of the lifting seat 8, a mounting base 11 fixedly connected to the top of the vertical plate 2, a control display 12 fixedly installed on the mounting base 11, and a first distance sensor 10 fixedly installed on the top surface of the inner cavity of the lifting groove 3.

[0026] In this embodiment, the first motor 6 can be controlled by the control display 12, and the first distance sensor 10 can detect the height of the lifting seat 8 and record the data separately for the user in the control display 12 so that the data from multiple measurements can be recalled and compared. The control display 12 is existing technology and has a control and storage system built in it, and can establish a database.

[0027] For details, please refer to Figures 1 to 4 The waist measurement mechanism 9 includes a storage box 13 fixedly connected to the front of the lifting seat 8. A stop block 14 is provided at the front of the storage box 13. A fixed hook 15 is fixedly connected to the front of the storage box 13. A second motor 16 is fixedly installed on the bottom surface of the storage box 13. The output shaft of the second motor 16 extends into the inner cavity of the storage box 13 and is fixedly connected to a rotating rod 17. A motor grating ruler 19 is fixedly installed on the top surface of the storage box 13. The input end of the motor grating ruler 19 extends into the inner cavity of the storage box 13 and is connected to the rotating rod 17. The top of 7 is connected, and a take-up drum 18 is fixedly sleeved on the outside of the rotating rod 17. A tape measure 20 is wound on the take-up drum 18. The end of the tape measure 20 extends to the outside of the abutment block 14 and is fixedly connected to a U-shaped hook 21. The U-shaped hook 21 is sleeved on the fixed hook 15. Multiple pressure sensors 22 are provided on the inner side of the tape measure 20, and scales 23 are provided on the outer side of the tape measure 20. A scanner 24 is fixedly installed in the inner cavity of the storage box 13. The detection end of the scanner 24 extends to the front of the storage box 13.

[0028] In this embodiment, the second motor 16, the motor grating ruler 19, the scanner 24, and the pressure sensor 22 are all electrically connected to the control display 12. The control display 12 can control the second motor 16, and at the same time, the control display 12 can display, store, and recall the data detected by the motor grating ruler 19, the scanner 24, and the pressure sensor 22. In addition, the scale 23 is set with specific values ​​so that the scanner 24 can scan. Furthermore, the scale 23 at the end of the tape measure 20 is a non-zero position, and the starting data of the scale 23 is the sum of the width of the abutment 14 and the length of the U-shaped hook 21.

[0029] For details, please refer to Figure 1 and Figure 2 Two columns 26 are fixedly connected to the top surface of the base plate 1, and a top plate 27 is fixedly connected to the top of the two columns 26. A second distance sensor 28 is fixedly installed on the bottom surface of the top plate 27.

[0030] In this embodiment, the distance between the bottom surface of the second distance sensor 28 and the top surface of the scale 25 is fixed. The distance between the second distance sensor 28 and the top of the user's head is detected by the second distance sensor 28. The user's height is obtained by subtracting the data measured by the second distance sensor 28 from the fixed distance. This process can be calculated and displayed by controlling the display 12.

[0031] For details, please refer to Figure 1 and Figure 2 A scale 25 is fixedly installed on the top surface of the base plate 1, and the scale 25 is located directly below the second distance sensor 28.

[0032] In this embodiment, the user's weight is measured by the scale 25, and the user's height is detected by the second distance sensor 28. The user's BMI is calculated by combining the weight and height, and the user's weight health is assessed.

[0033] For details, please refer to Figure 1 The bottom surface of the base plate 1 is fixedly connected with multiple support feet 29.

[0034] In this embodiment, the base plate 1 is supported by multiple support feet 29.

[0035] For details, please refer to Figure 2 The inner cavity of the lifting groove 3 is fixedly fitted with two slide rods 7, and the two slide rods 7 are respectively movably fitted with the lifting seat 8.

[0036] In this embodiment, the lifting seat 8 is limited by the movable cooperation between the slide rod 7 and the lifting seat 8, so that the lifting seat 8 can only move along the axial direction of the lead screw 5.

[0037] Working principle: In use, the person trying to lose weight first stands on the weighing scale 25 on the top surface of the base plate 1. The weighing scale 25 weighs the person, and at the same time, the second distance sensor 28 detects the user's height to calculate the user's BMI data. Then, the first motor 6 is started to drive the lead screw 5 to rotate. Through the threaded engagement between the lead screw 5 and the lifting seat 8, the lifting seat 8 and the storage box 13 move up and down, so that the height of the storage box 13 matches the height of the user's waist and abdomen. At this time, the first distance sensor 10 detects the height of the lifting seat 8 and stores the data monitored by the first distance sensor 10 in the control display 12, and a database is created for this user. Then, the second motor 1 is started. 6. The winding drum 18 rotates, simultaneously pulling the U-shaped hook 21 at one end of the measuring tape 20, allowing the measuring tape 20 on the winding drum 18 to be fully released. At the same time, the U-shaped hook 21 at the end of the measuring tape 20 is looped around the user's waist and hooked onto the fixed hook 15, bringing the user's abdomen into contact with the front of the abutment block 14. At this point, the second motor 16 is activated, causing the winding drum 18 to reverse and rewind the measuring tape 20, gradually bringing the inner side of the measuring tape 20 into contact with the user's waist and abdomen. When the pressure sensor 22 on the inner side of the measuring tape 20 receives a predetermined pressure, the second motor 16 stops. The scanner 24 scans and identifies the data on the scale 23 on the outer side of the measuring tape 20 at this moment, and the control display 12 displays the data. The data displayed and stored is the user's waist circumference. Additionally, during the winding process, the second motor 16 drives the take-up drum 18 to rotate, while the motor grating ruler 19 measures the number of rotations and angles of the rotating rod 17 and the take-up drum 18. Simultaneously, the control display 12 stores the measured waist circumference data. Finally, when the user undergoes another measurement after weight loss, the data stored in the user's first distance sensor 10 on the control display 12 is retrieved. The first motor 6 drives the lead screw 5 to rotate, and through the cooperation between the lead screw 5 and the lifting seat 8, the lifting seat 8 and the storage box 13 are moved to the user's waist height. Then, the measuring tape 20 is pulled out of the storage box 13 again, connecting the U-shaped hook 21 at the end of the measuring tape 20 to the fixed hook 15. The measuring tape 20 is then wrapped around the patient's waist. The second motor 16 is activated to drive the winding drum 18 to wind up the measuring tape 20. Simultaneously, a motor grating ruler 19 detects the number of rotations and angles of the rotating rod 17 and the winding drum 18, ensuring that the number of rotations and angles detected by the motor grating ruler 19 are equal to those detected in the previous waist circumference measurement. The area of ​​waist reduction is visually observed through the gap between the inside of the measuring tape 20 and the user's waist and abdomen. The second motor 16 is then activated again to drive the winding drum 18 to wind up the measuring tape 20 until the pressure sensor 22 inside the measuring tape 20 receives a predetermined pressure. The scanner 24 then scans and saves the user's waist circumference data on the measuring tape 20 for later comparison.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
