Description

Technical Field

[0001] This application relates to the field of foot shape and foot pressure detection equipment, and in particular to a dual-foot adjustable footprint collection device. Background Technology

[0002] When people perform basic daily movements, such as standing, walking, and running, the soles of their feet are the main parts that come into contact with the external environment. Detecting the distribution of pressure on the soles of the feet can not only effectively reflect the structure of the feet, but also, through methods such as inverse dynamics, calculate the force on various skeletal and muscular parts of the human body, enabling more precise biomechanical experimental analysis of the human body structure.

[0003] Most existing footprint collection devices work by having the user step on a specific area of ​​blue-printed paper. Data is collected by observing the shape of the paper underneath, which is then imprinted with ink from the back of the paper. For portability and storage, box-type or container-type measuring devices are often used. These devices typically have only one measuring position, meaning that only one foot can be used at a time. This can lead to the user's feet being in an unnatural distance during measurement, making it difficult to accurately reflect the force and shape of the feet in a natural standing posture. This introduces errors and affects measurement efficiency and accuracy. Summary of the Invention

[0004] To improve measurement accuracy, this application provides a dual-foot adjustable footprint acquisition device.

[0005] This application provides a dual-foot adjustable footprint collection device, which adopts the following technical solution: A dual-foot adjustable footprint collection device includes a fixed foot half-box and a movable foot half-box, which are rotatably connected. A fixed foot measuring component is provided in the fixed foot half-box, and a movable foot measuring component is movably provided in the movable foot half-box. Locking components are provided on the fixed foot half-box and the movable foot half-box. Foot placement areas are provided on the inner walls of both the fixed foot half-box and the movable foot half-box. When the fixed foot half-box and the movable foot half-box are opened 180°, they are in the measuring state; when the fixed foot half-box and the movable foot half-box are closed, they are in the storage state.

[0006] By adopting the above technical solution, a closable box is formed by rotating the fixed-foot half-box and the movable-foot half-box. When the box is unfolded to a 180° measurement state, it becomes a stable platform. When the box is folded up, it closes to reduce space occupation and facilitates carrying. The locking component ensures the stability of the folded state. When measurement is required, the person measuring stands in the foot placement area, the movable-foot measuring component moves and adjusts its position, and then the person measuring places their feet on the measurement positions of the fixed-foot measuring component and the movable-foot measuring component respectively, thereby achieving the effect of simultaneous measurement by both feet and improving measurement accuracy.

[0007] Optionally, the foot measurement component includes a fixed frame and a sliding frame. The fixed frame is symmetrically arranged on the two inner walls of the foot half-box. A sliding column is provided on the outer side of the sliding frame. The sliding column slides and cooperates with the fixed frame. A first step measuring element is provided on the inner wall of the sliding frame. The sliding frame is located between the opening of the foot half-box and the foot placement area of ​​the foot half-box.

[0008] By adopting the above technical solution, the sliding frame forms a sliding fit with the fixed frame fixed on the inner wall through the sliding column on the outside, allowing the sliding frame to slide and rotate under the constraint of the fixed frame. If necessary, it can also rotate slightly, which facilitates the placement of paper for collecting foot data and the reset operation.

[0009] Optionally, the movable foot measuring component includes a sliding frame and a moving frame. The sliding frame is slidably connected to the inner wall of the movable foot half-box. The moving frame and the sliding frame are movably coupled. The inner wall of the moving frame is provided with a second stepping element. The movable foot half-box is provided with an adjusting element for driving the sliding frame to move. The moving frame is located between the opening of the movable foot half-box and the foot placement area of ​​the movable foot half-box.

[0010] By adopting the above technical solution, the entire moving foot measuring component becomes a movable part and is driven by an independent adjusting component. When the adjusting component is working, it drives the sliding frame and the moving frame to move, thereby changing the distance between the moving frame and the fixed foot side component.

[0011] Optionally, the inner wall of the movable foot half-box is provided with a slide rail, the sliding frame slides in conjunction with the slide rail, the adjusting component includes a threaded rod, the extension direction of the threaded rod is consistent with the extension direction of the slide rail, the threaded rod is rotatably connected to the movable foot half-box, and the threaded rod is threadedly connected to the sliding frame.

[0012] By adopting the above technical solution, when the sliding frame needs to be moved, simply rotate the threaded rod to drive the sliding frame and the sliding frame to slide, thereby adjusting the distance between the moving frame and the fixed foot measuring component.

[0013] Optionally, a first measuring frame is placed inside the fixed-foot half-box, and a second measuring frame is placed inside the movable-foot half-box. A first shoulder width plate is slidably connected to the first measuring frame, and the surface of the first shoulder width plate is perpendicular to the sliding direction of the first shoulder width plate. A second shoulder width plate is slidably connected to the second measuring frame, and the surface of the second shoulder width plate is perpendicular to the sliding direction of the second shoulder width plate. The first measuring frame and the second measuring frame are provided with a locking assembly.

[0014] By adopting the above technical solution, the first measuring frame and the second measuring frame are connected, and the outer width of the human body's two shoulders can be measured through the first shoulder width plate and the second shoulder width plate. This makes it easier to determine the distance between the moving frame and the fixed foot measuring component. The locking component is used to quickly assemble and fix the first measuring frame and the second measuring frame.

[0015] Optionally, the first measuring frame has a first sliding groove, and the first shoulder plate has a first slider. The first slider slides in conjunction with the first sliding groove. A first screw is rotatably connected in the first sliding groove, and the first screw is threadedly connected to the first slider. The second measuring frame has a second sliding groove, and the second shoulder plate has a second slider. The second slider slides in conjunction with the second sliding groove. A second screw is rotatably connected in the second sliding groove, and the second screw is threadedly connected to the second slider. When the first measuring frame and the second measuring frame are close together, the end of the first screw and the end of the second screw are inserted into each other. The thread direction of the first screw is opposite to the thread direction of the second screw.

[0016] By adopting the above technical solution, the first and second screws with opposite thread directions can be used to drive the first and second shoulder width plates respectively. When the first and second screws are inserted and rotate synchronously, the first and second shoulder width plates move towards or away from each other at the same time due to the opposite thread directions, ensuring that the measurement center point remains unchanged, improving measurement efficiency and symmetry accuracy, and facilitating the measurement of both shoulders.

[0017] Optionally, a first back plate is provided between the first shoulder width plate and the first slider, and the first back plate is perpendicular to the first shoulder width plate; a second back plate is provided between the second shoulder width plate and the second slider, and the second back plate is perpendicular to the second shoulder width plate.

[0018] By adopting the above technical solution, the backplate can fit the back of the person being measured, providing an additional positioning reference and reducing lateral movement and twisting of the torso during the measurement process, thereby ensuring that shoulder width data is obtained in a stable posture.

[0019] Optionally, a first limiting block is provided on the first shoulder width plate, a first limiting groove adapted to the first protrusion is provided on the foot measuring component, a second limiting block is provided on the second shoulder width plate, a second limiting groove adapted to the second protrusion is provided on the moving frame, an insert is provided at one end of the first measuring frame, and a slot adapted to the insert is provided at one end of the second measuring frame.

[0020] By adopting the above technical solution, the cooperation between the insert and the slot can provide positioning for the connection of the first measuring frame and the second measuring frame. After measuring the distance between the shoulders, the distance between the moving frame and the fixed foot measuring component is adjusted. When the first limiting block can be inserted into the first limiting slot and the second limiting block can also be inserted into the second limiting slot, it means that the test distance between the moving frame and the fixed foot measuring component has been adjusted to match the distance of the measured shoulders.

[0021] Optionally, the end of the first screw is provided with a polygonal block, and the end of the second screw is provided with a polygonal groove, the polygonal groove being adapted to the polygonal block.

[0022] By adopting the above technical solution, it is ensured that the first screw and the second screw can only be inserted when they are aligned at a specific angle, reducing the misalignment of the thread starting point caused by arbitrary insertion, and ensuring the synchronization and symmetry of the movement of the first shoulder plate and the second shoulder plate during rotation.

[0023] Optionally, the inner wall of the fixed-foot half-box is rotatably connected to a first placement frame for placing the first measuring frame, the first back plate, and the first shoulder width plate, and the inner wall of the movable-foot half-box is rotatably connected to a second placement frame for placing the second measuring frame, the second back plate, and the second shoulder width plate.

[0024] By adopting the above technical solution, the first and second placement frames are rotated during measurement to avoid obstructing the foot placement area, and the first and second measuring frames are rotated and unfolded during storage to place them securely inside the box, reducing shaking and damage during transportation.

[0025] Optionally, the outer wall of the fixed-foot half-box is provided with a first handle, and the side of the fixed-foot half-box away from the first handle is provided with a first bottom block. The outer wall of the movable-foot half-box is provided with a second handle, and the side of the movable-foot half-box away from the second handle is provided with a second bottom block. When the fixed-foot half-box and the movable-foot half-box are opened 180°, the first bottom block abuts against the movable-foot half-box. When the fixed-foot half-box and the movable-foot half-box are opened 180°, the second bottom block abuts against the fixed-foot half-box.

[0026] By adopting the above technical solution, the first and second bottom blocks serve as support legs for the box when it is stored. When it is unfolded to 180°, the bottom blocks abut against the bottom of the box, ensuring that the fixed-foot half-box and the movable-foot half-box are unfolded to a horizontal and coplanar state, thereby improving measurement stability.

[0027] Optionally, when the fixed-foot half-box and the movable-foot half-box are opened 180°, the first bottom block and the second bottom block are close together. A sliding rod is slidably connected on the first bottom block, and a sliding groove for inserting the sliding rod is provided on the second bottom block.

[0028] By adopting the above technical solution, when the bottom block abuts against the bottom of the box, the sliding rod can be inserted into the sliding groove to lock the first bottom block and the second bottom block, thus maintaining measurement stability.

[0029] In summary, this application includes at least one of the following beneficial technical effects: 1. A closable box is formed by rotating the fixed-foot half-box and the movable-foot half-box. When the box is unfolded to 180° for measurement, it becomes a stable platform. When the box is folded up, it closes to reduce space occupation and make it easy to carry. The locking component is used to ensure the stability of the folded state. When measurement is required, the person measuring stands in the foot placement area, the movable-foot measuring component moves and adjusts its position, and then the person measuring places their feet on the measuring positions of the fixed-foot measuring component and the movable-foot measuring component respectively, thereby achieving the effect of measuring with both feet at the same time and improving measurement accuracy. 2. The sliding frame forms a sliding fit with the fixed frame fixed on the inner wall through the sliding column on the outside, allowing the sliding frame to slide and rotate under the constraint of the fixed frame. It can also rotate slightly when necessary, which facilitates the placement of paper for collecting foot data and the resetting operation. 3. Make the entire moving foot measuring component a movable part, and drive it through an independent adjusting component. When the adjusting component is working, it drives the sliding frame and the moving frame to move, thereby changing the distance between the moving frame and the fixed foot side component.

Detailed Implementation

[0037] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0038] This application discloses a dual-foot adjustable footprint collection device.

[0039] Reference Figure 1 A dual-foot adjustable footprint acquisition device includes a fixed foot half-box 1 and a movable foot half-box 2, which are rotatably connected and can be opened and closed by rotation. A fixed foot measuring component is installed in the fixed foot half-box 1, and a movable foot measuring component is movably installed in the movable foot half-box 2. Locking components are provided on both the fixed foot half-box 1 and the movable foot half-box 2, including a fixed latch 21 and a rotating latch 11. The fixed latch 21 is fixed to the outer wall of the movable foot half-box 2, and the rotating latch 11 is rotatably connected to the fixed foot half-box 2. The outer wall of box 1, the inner wall of fixed foot half box 1, and the inner wall of movable foot half box 2 are all provided with foot placement areas. When fixed foot half box 1 and movable foot half box 2 are opened 180°, they are in the measurement state. When fixed foot half box 1 and movable foot half box 2 are closed, they are in the storage state. In the storage state, the rotating lock 11 is close to the fixed lock 21. In this state, the rotating lock 11 can be locked onto the fixed lock 21 by rotating. In the storage state, the inner wall of fixed foot half box 1 away from movable foot half box 2 and the inner wall of movable foot half box 2 away from fixed foot half box 1 are both foot placement areas.

[0040] When foot measurements are required, the fixed foot half-box 1 and the movable foot half-box 2 can be opened 180° and placed on the ground. The movable foot measuring component can then be moved, adjusting the relative distance between the measuring positions of the fixed and movable foot measuring components to approximately the width of the observer's shoulder. The observer can then stand in the foot placement area of ​​the fixed and movable foot half-boxes 1 and 2, first placing one foot on the measuring position of the fixed foot measuring component, and then placing the other foot on the measuring position of the movable foot measuring component. This allows the observer to take foot measurements with their feet approximately shoulder-width apart. The measurement can measure data from both feet simultaneously, improving the accuracy of the measurement data. When it is necessary to reduce the slight deviation of the other foot during the process of moving one foot onto the movable foot measurement component, a chair can be used to allow the measurer to be in a seated position. Place both feet in the foot placement areas of the fixed foot half-box 1 and the movable foot half-box 2. After adjusting the position of the movable foot measurement component, place both feet on the measurement positions of the fixed foot measurement component and the movable foot measurement component respectively while seated, and then change to a standing position to achieve the effect of measuring both feet at the same time, reducing measurement deviation and improving measurement accuracy.

[0041] Reference Figure 1 and Figure 2 The foot-fixing measuring component includes a fixed frame 31 and a sliding frame 32. The fixed frame 31 is symmetrically arranged on the two inner walls of the foot-fixing half-box 1. The fixed frame 31 is a strip-shaped frame with transverse waist-shaped holes on its side walls. Sliding columns 33 are fixedly arranged on both opposite outer sides of the sliding frame 32. The sliding columns 33 are close to the side wall edges of the sliding frame 32 and slide in conjunction with the fixed frame 31. The sliding columns 33 are cylindrical, allowing them to slide within the waist of the fixed frame 31. The sliding frame 32 can slide and rotate through the sliding column 33. In the measurement state, the sliding column 33 is close to the end of the fixed frame 31 away from the moving foot half box 2. The inner wall of the sliding frame 32 is provided with a first stepping test member 34. In this embodiment, the first stepping test member 34 is blue printing paper. The sliding frame 32 is located between the opening of the fixed foot half box 1 and the foot placement area of ​​the fixed foot half box 1. There is a gap between the sliding frame 32 and the foot placement area of ​​the fixed foot half box 1.

[0042] When measurement is required, the sliding frame 32 can be slid and rotated to flip the sliding frame 32 and the first foot measuring piece 34 so that the non-stepping surface of the first foot measuring piece 34 faces upward. Ink can then be applied to the non-stepping surface of the first foot measuring piece 34. Paper for collecting foot data is placed below the sliding frame 32. Then, the sliding frame 32 and the first foot measuring piece 34 are flipped so that the stepping surface of the first foot measuring piece 34 faces upward. The sliding column 33 is slid to the end of the fixed frame 31 away from the waist-shaped hole and the moving foot half-box 2. Then, the foot can be stepped on the first foot measuring piece 34 to perform the measurement.

[0043] Reference Figure 1 and Figure 3The movable foot measuring component includes a sliding frame 41 and a moving frame 42. The sliding frame 41 is slidably connected to the inner wall of the movable foot half-box 2. In the measuring state, the sliding frame 41 can slide closer to or further away from the fixed foot half-box 1. The moving frame 42 and the sliding frame 41 are movably coupled. Moving columns 43 are fixedly installed on both opposite outer sides of the moving frame 42. The moving columns 43 are in the shape of a column and are close to the side wall edge of the moving frame 42. The side wall of the sliding frame 41 has a transverse waist-shaped groove. The moving columns 43 and the waist-shaped groove of the sliding frame 41 are connected. With sliding engagement, the moving column 43 can rotate within the waist-shaped groove of the sliding frame 41, and the moving frame 42 can slide and rotate through the moving column 43. In the measurement state, the moving column 43 and the end of the waist-shaped groove of the sliding frame 41 away from the fixed foot half-box 1 are close together. The inner wall of the moving frame 42 is provided with a second stepping element 44. In this embodiment, the second stepping element 44 is blue printing paper. The movable foot half-box 2 is provided with an adjustment element for driving the sliding frame 41 to move. The moving frame 42 is located between the opening of the movable foot half-box 2 and the foot placement area of ​​the movable foot half-box 2.

[0044] When measurement is required, the movable frame 42 can be slid and rotated to flip it over. Ink is applied to the non-stepping surface of the second foot measuring piece 44. Paper for collecting foot data is placed under the movable frame 42. Then, the movable frame 42 and the second foot measuring piece 44 are flipped over so that the stepping surface of the second foot measuring piece 44 faces upward. The movable column 43 is slid to the end of the waist-shaped groove of the sliding frame 41 away from the fixed foot half box 1. Then, the sliding frame 41 and the sliding frame 32 are moved by the adjusting component to adjust the distance between the movable frame 42 and the sliding frame 32, so that the distance between the measurer's two feet is close to the shoulder width, thereby improving the measurement accuracy.

[0045] The two symmetrical inner walls of the movable foot half-box 2 are provided with slide rails 22. The sliding frame 41 slides and engages with the slide rails 22. The extension direction of the slide rails 22 is consistent with the sliding direction of the sliding frame 41. The adjusting component includes a threaded rod 23. The extension direction of the threaded rod 23 is consistent with the extension direction of the slide rails 22. One end of the threaded rod 23 is rotatably connected to the inner wall of the movable foot half-box 2, and the other end extends out of the movable foot half-box 2. A knob is provided at the end of the threaded rod 23 away from the movable foot half-box 2. The threaded rod 23 is threadedly connected to the sliding frame 41.

[0046] When the sliding frame 41 needs to be moved, simply rotate the threaded rod 23 to move the sliding frame 41 and the sliding frame 32, thereby adjusting the distance between the moving frame 42 and the sliding frame 32.

[0047] Reference Figure 1 and Figure 4A first measuring frame 5 is placed inside the fixed-foot half-box 1, and a second measuring frame 6 is placed inside the movable-foot half-box 2. Both the first measuring frame 5 and the second measuring frame 6 extend in a straight line. A first shoulder width plate 51 is slidably connected to the first measuring frame 5, and the sliding direction of the first shoulder width plate 51 is consistent with the extension direction of the first measuring frame 5. The surface of the first shoulder width plate 51 is perpendicular to the sliding direction of the first shoulder width plate 51. A second shoulder width plate 61 is slidably connected to the second measuring frame 6, and the sliding direction of the second shoulder width plate 61 is perpendicular to the sliding direction of the second shoulder width plate 6. The second shoulder plate 61 extends in the same direction as the second measuring frame 6. The surface of the second shoulder plate 61 is perpendicular to the sliding direction of the second shoulder plate 61. The first measuring frame 5 and the second measuring frame 6 are provided with a locking assembly. The locking assembly includes a mounting lock 52 and a connecting lock 62. The mounting lock 52 is mounted on the first measuring frame 5, and the connecting lock 62 is rotatably connected to the second measuring frame 6. When the first measuring frame 5 and the second measuring frame 6 are close to each other, the connecting lock 62 can be rotated and fastened to the mounting lock 52.

[0048] When it is necessary to adjust the distance between the moving frame 42 and the sliding frame 32, the first measuring frame 5 and the second measuring frame 6 can be taken out and connected by the locking assembly. After connection, the measurer's shoulders are positioned between the first shoulder width plate 51 and the second shoulder width plate 61. The first shoulder width plate 51 and the second shoulder width plate 61 are moved so that their surfaces abut against the measurer's shoulders, thereby measuring the approximate distance between the shoulders. After measurement, the first shoulder width plate 51 and the second shoulder width plate 61 are brought closer to the moving frame 42 and the sliding frame 32. At the same time, the threaded rod 23 is rotated to adjust the distance between the moving frame 42 and the sliding frame 32 according to the first shoulder width plate 51 and the second shoulder width plate 61, so that the measurement position is close to the shoulder width, thereby improving the measurement accuracy. After measurement, the first measuring frame 5 and the second measuring frame 6 can be disassembled and stored in the fixed foot half box 1 and the moving foot half box 2, respectively.

[0049] A first sliding groove 53 is provided at one end of the first measuring frame 5. A first slider 54 is provided on the first shoulder plate 51. The first slider 54 slides and engages with the first sliding groove 53. A first screw 55 is rotatably connected in the first sliding groove 53. The first screw 55 is threadedly connected to the first slider 54. One end of the first screw 55 passes through the end of the first measuring frame 5. A knob is provided at the end of the first screw 55 passing through the first measuring frame 5. A second sliding groove 63 is provided at one end of the second measuring frame 6. A second slider 64 is provided on the second shoulder plate 61. The second slider 64 slides and engages with the second sliding groove 63. A second screw 65 is rotatably connected in the second sliding groove 63. The second screw 65 is threadedly connected to the second slider 64. When the end of the first measuring frame 5 with the first sliding groove 53 and the end of the second measuring frame 6 with the second sliding groove 63 are close to each other, the end of the first screw 55 and the end of the second screw 65 are inserted and engaged. The thread direction of the first screw 55 is opposite to the thread direction of the second screw 65.

[0050] When measuring the shoulders of the person being measured using the first shoulder width plate 51 and the second shoulder width plate 61, one end of the first measuring frame 5 with the first groove 53 and the other end of the second measuring frame 6 with the second groove 63 can be brought close together, so that the first screw 55 and the second screw 65 can be inserted. Then, the connecting lock 62 can be rotated and locked onto the mounting lock 52, so that the shoulders of the person being measured are positioned between the first shoulder width plate 51 and the second shoulder width plate 61. Rotating the first screw 55 will drive the second screw 65 to rotate, and the distance between the first shoulder width plate 51 and the second shoulder width plate 61 can be adjusted to measure the shoulders.

[0051] A first back plate 56 is provided between the first shoulder width plate 51 and the first slider 54, and the first back plate 56 is perpendicular to the first shoulder width plate 51. A second back plate 66 is provided between the second shoulder width plate 61 and the second slider 64, and the second back plate 66 is perpendicular to the second shoulder width plate 61. When measuring the shoulders, the first back plate 56 and the second back plate 66 can abut against the back of the person being measured, improving stability. At the same time, the first back plate 56 and the second back plate 66 can reduce the manufacturing length of the first measuring frame 5 and the second measuring frame 6, making it easier to put them into the fixed foot half box 1 and the movable foot half box 2 for storage.

[0052] A first limiting block 57 is provided on the side of the first shoulder width plate 51 away from the first measuring frame 5. A first limiting groove adapted to the first protrusion is provided on the foot measuring component. The first limiting groove is provided on the sliding frame 32 and is used for the insertion of the first limiting block 57. A second limiting block 67 is provided on the side of the second shoulder width plate 61 away from the second measuring frame 6. A second limiting groove adapted to the second protrusion is provided on the moving frame 42 and is used for the insertion of the second limiting block 67. An insert 58 is provided at one end of the first measuring frame 5, and a slot 68 adapted to the insert 58 is provided at one end of the second measuring frame 6.

[0053] After measuring the shoulders using the first shoulder width plate 51 and the second shoulder width plate 61, the distance between the moving frame 42 and the sliding frame 32 is adjusted until the first screw 55 and the second screw 65 are inserted into the first limiting block 57 and the second limiting block 67, respectively. Since the first shoulder width plate 51 and the second shoulder width plate 61 measure the maximum distance between the shoulders, the actual distance between the feet should correspond to the shoulder bones. Therefore, after the first limiting block 57 and the second limiting block 67 are inserted into the first limiting slot and the second limiting slot, the distance between the feet when stepping on the first step measuring piece 34 and the second step measuring piece 44 is easily aligned with the shoulder bones, thus improving the measurement accuracy.

[0054] Reference Figure 4 and Figure 5The end of the first screw 55 is provided with a polygonal block 551, which is a trapezoidal block. The end of the second screw 65 is provided with a polygonal groove 651, which is a trapezoidal groove. The shape and size of the polygonal groove 651 are adapted to the shape and size of the polygonal block 551.

[0055] After the first screw 55 and the second screw 65 are inserted, rotating the first screw 55 will drive the second screw 65 to rotate, so that the first screw 55 and the second screw 65 can be rotated to the same angle before they can be inserted. This ensures that the positions of the first shoulder width plate 51 and the second shoulder width plate 61 are symmetrical, which helps to ensure the accuracy of the measurement.

[0056] The inner walls of the fixed-foot half-box 1 and the movable-foot half-box 2 are both rotatably connected to rotating rods. The inner wall of the fixed-foot half-box 1 is rotatably connected to a first placement frame 12 for placing the first measuring frame 5, the first back plate 56, and the first shoulder width plate 51. The first placement frame 12 is rotatably connected to the inner wall of the fixed-foot half-box 1 via rotating rods. The first placement frame 12 has grooves for placing the first measuring frame 5, the first back plate 56, and the first shoulder width plate 51. The inner wall of the movable-foot half-box 2 is rotatably connected to a second placement frame 24 for placing the second measuring frame 6, the second back plate 66, and the second shoulder width plate 61. The second placement frame 24 is rotatably connected to the inner wall of the movable-foot half-box 2 via rotating rods. The second placement frame 24 has grooves for placing the second measuring frame 6, the second back plate 66, and the second shoulder width plate 61. Both the first placement frame 12 and the second placement frame 24 are provided with hooks.

[0057] When measurement is not required, the first measuring frame 5, the first back plate 56, the first shoulder width plate 51, the second measuring frame 6, the second back plate 66, and the second shoulder width plate 61 can be stored using the first placement frame 12 and the second placement frame 24. In the measurement state, the rotating rod on the inner wall of the fixed foot half box 1 and the first placement frame 12 can be rotated so that the hook of the first placement frame 12 is fastened at the opening of the fixed foot half box 1. The rotating rod on the inner wall of the movable foot half box 2 and the second placement frame 24 can be rotated so that the hook of the second placement frame 24 is fastened at the opening of the movable foot half box 2, thereby leaving space for the foot placement area to be stepped on by both feet.

[0058] Reference Figure 1 and Figure 6The fixed-foot half-box 1 has a first handle 13 on its outer wall and a first base block 14 on the side away from the first handle 13. The movable-foot half-box 2 has a second handle 25 on its outer wall and a second base block 26 on the side away from the second handle 25. When the fixed-foot half-box 1 and the movable-foot half-box 2 are opened 180°, the first base block 14 abuts against the movable-foot half-box 2. When the fixed-foot half-box 1 and the movable-foot half-box 2 are opened 180°, the second base block 26 abuts against the fixed-foot half-box 1. When the fixed-foot half-box 1 and the movable-foot half-box 2 are in the storage state, they can be carried and moved by holding the first handle 13 and the second handle 25. When placed on the ground, the first base block 14 and the second base block 26 can provide a cushioning effect. When the fixed-foot half-box 1 and the movable-foot half-box 2 are opened, the first base block 14 and the second base block 26 can provide a limiting effect to reduce the excessive rotation of the fixed-foot half-box 1 and the movable-foot half-box 2 when they are opened.

[0059] When the fixed-foot half-box 1 and the movable-foot half-box 2 are opened 180°, the first bottom block 14 and the second bottom block 26 are close together. A sliding rod 15 is slidably connected to the first bottom block 14. The sliding rod 15 is an L-shaped rod. The side wall of the second bottom block 26 is provided with a sliding groove 27 for the sliding rod 15 to be inserted. When the first bottom block 14 and the second bottom block 26 are close together, the sliding rod 15 can be inserted into the sliding groove 27 by sliding.

[0060] After the fixed foot half-box 1 and the movable foot half-box 2 are opened 180°, the movable sliding rod 15 is inserted into the sliding groove 27, so that the fixed foot half-box 1 and the movable foot half-box 2 are stably in the measurement state, thereby ensuring the stability and accuracy of the measurement.

[0061] The implementation principle of the adjustable footprint collection device according to this application embodiment is as follows: In the measurement state where the fixed foot half-box 1 and the movable foot half-box 2 are extended 180°, the sliding frame 41 and the moving frame 42 are moved by the adjusting component, adjusting the distance between the moving frame 42 and the sliding frame 32 so that the foot placement is close to the natural shoulder width of the person being measured. When further determination of the foot spacing is needed, the first measuring frame 5 and the second measuring frame 6 can be connected. The shoulder width is measured by moving the first shoulder width plate 51 and the second shoulder width plate 61. Then, the first limiting block 57 and the second limiting block 67 are inserted into the first limiting groove and the second limiting groove respectively, thereby further determining the distance between the moving frame 42 and the sliding frame 32. Before measurement, ink is applied to the non-stepping surfaces of the first foot measuring piece 34 and the second foot measuring piece 44 by sliding and flipping. Paper for collecting foot data is placed below the sliding frame 32 and the moving frame 42. During measurement, the user stands in the foot placement area of ​​the fixed foot half-box 1 and the moving foot half-box 2, first stepping one foot on the first foot measuring piece 34, and then stepping the other foot on the second foot measuring piece 44. This allows the user to measure foot data with the distance between their feet close to shoulder width. When it is necessary to reduce the deviation, the user can first sit with both feet in the foot placement area, adjust, and then step on the first foot measuring piece 34 and the second foot measuring piece 44 at the same time to stand up, thereby improving the measurement accuracy.

[0062] The above are all preferred embodiments of this application. These embodiments are only explanations of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
