[0033] Based on any of the above schemes, the positioning device 200 includes a patella positioning block 210 and a position positioning ruler 220, the patella positioning block 210 is slidably connected to the middle part of the main frame 100, the middle part of the position positioning ruler 220 is connected to the patella positioning block 210, one end of the position positioning ruler 220 is connected to the upper measuring ruler 300, and the other end of the position positioning ruler 220 is connected to the lower measuring ruler 400.

[0034] When measuring leg circumference, the patella positioning block 210 is adjusted to a suitable position according to people of different heights, and the patella of the leg to be measured is placed at the corresponding position of the patella positioning block 210. According to the position positioning ruler 220, the upper measuring ruler 300 and the lower measuring ruler 400 are adjusted to the positions above and below the patella to be measured, respectively, thereby ensuring the accuracy of the measurement position and completing the required leg circumference measurement work at the same time. The operation is convenient, saving time and effort.

[0035] On the basis of any of the above solutions, a positioning groove is provided at one end of the patella positioning block 210 .

[0036] By providing the positioning groove, the patella part and the patella positioning block 210 are more closely fitted, thereby making the measurement data more accurate.

[0037] Optionally, a sponge or other latex material component is provided in the positioning groove.

[0038] By providing a sponge or other latex material component, the patella part and the patella positioning block 210 can fit more closely.

[0039] On the basis of any of the above solutions, a fixing plate 20 is provided at the other end of the patella positioning block 210 , and the zero scale line of the position positioning ruler 220 is fixedly connected to the fixing plate 20 .

[0040] By setting the fixing plate 20, the zero scale line of the position positioning ruler 220 and the patella positioning block 210 are fixed, so that when the patella positioning block 210 is adjusted, the zero scale of the position positioning ruler 220 and the patella positioning block 210 are adjusted together as a whole, and the zero scale line of the position positioning ruler 220 serves as a reference position relative to the patella positioning block 210 and does not move, thereby facilitating subsequent adjustments to determine the specific measurement position of the leg.

[0041] Specifically, a protrusion 50 is provided at the end of the upper ruler 300 and the lower ruler 400 opposite to the placement of the legs, a strip slot hole 1 is provided at the lower end of the protrusion 50 of the upper ruler 300, and a strip slot hole 1 is provided at the upper end of the protrusion 50 of the lower ruler 400. One end of the position positioning ruler 220 passes through the strip slot hole 1 and is wound in the protrusion 50 of the upper ruler 300, and the other end of the position positioning ruler 220 passes through the strip slot hole 2 and is wound in the protrusion 50 of the lower ruler 400.

[0042] By wrapping the ends of the position locator 220 within the bumps 50 of the upper and lower rulers 300 and 400, respectively, the position locator 220, wrapped within the bumps 50, is pulled out when the upper ruler 300 slides upward or the lower ruler 400 slides downward. When the upper ruler 300 slides downward or the lower ruler 400 slides upward, the position locator 220 is retracted into the bumps 50, thereby facilitating adjustment and determining the specific measurement locations above and below the patella. Furthermore, when the position of the upper or lower ruler 300, 400 needs to be adjusted, the bumps 50 can be used as handles, allowing the rulers to be grasped and slid up and down for easy adjustment.

[0043] On the basis of any of the above solutions, a locking hole 30 and a locking pin 40 are provided on one side of the patella positioning block 210 , and the locking pin 40 is threadedly connected to the locking hole 30 .

[0044] After the position of the patella positioning block 210 is adjusted, the locking pin 40 is screwed so that the locking pin 40 is pressed against the main frame 100, thereby fixing the patella positioning block 210. During the measurement process, the patella positioning block 210 is prevented from loosening and causing displacement in the upper, lower, left or right position, thereby preventing inaccurate measurement data.

[0045] On the basis of any of the above schemes, two slide rails 110 are provided on the main frame 100, and sliders 900 are provided on both sides of the upper ruler 300 and both sides of the lower ruler 400. The sliders 900 on both sides of the upper ruler 300 correspond one-to-one to the upper ends of the two slide rails 110 and are slidably connected, and the sliders 900 on both sides of the lower ruler 400 correspond one-to-one to the lower ends of the two slide rails 110 and are slidably connected.

[0046] By setting two slide rails 110 on the main frame 100, sliders 900 are set on both sides of the upper ruler 300 and the lower ruler 400, which correspond to the upper and lower ends of the two slide rails 110 respectively and are slidably connected, thereby facilitating the adjustment of the upper ruler 300 and the lower ruler 400, and further determining the specific positions above and below the patella that need to be measured.

[0047] Specifically, the cross section of the slide rail 110 is dovetail-shaped, rectangular or other special shapes, and the corresponding slider 900 is a dovetail block, a rectangular block or other special-shaped blocks.

[0048] Based on any of the above solutions, a tape measure 500 is wound inside the upper measuring ruler 300 and the lower measuring ruler 400. A window 600 is opened on one side of each of the upper measuring ruler 300 and the lower measuring ruler 400, and the free end of the tape measure 500 extends from the window 600.

[0049] When the specific measurement positions above and below the patella are determined, the tape measure 500 is pulled out through the window 600 to measure the leg circumference; when the measurement is completed, the tape measure 500 is retracted through the window 600 and wound inside the upper measuring ruler 300 and the lower measuring ruler 400, thereby facilitating storage and measurement.

[0051] When measuring the leg circumference, after the tape measure 500 is wrapped around the measuring part, the buckle 510 is placed in the corresponding positioning hole 700. At this time, the tape measure 500 is fixed in position, so as to facilitate recording the measurement data of the leg circumference.

[0052] Specifically, push buttons 800 are provided on the upper end surfaces of the upper measuring ruler 300 and the lower measuring ruler 400 .

[0053] In a specific example, after the tape measure 500 is placed around the leg to be measured, the corresponding buckles 510 of the upper ruler 300 and the lower ruler 400 are snapped into the corresponding positioning holes 700. At this time, by pressing the push button 800, the tape measure 500 is further tightened, thereby making the measurement data more accurate.

[0054] On the basis of any of the above solutions, it further includes a base 10 , and the main frame 100 is fixedly installed on the base 10 .

[0055] The main frame 100 is fixed on the base 10, making the entire leg circumference measuring device more stable and avoiding the problem of the leg circumference measuring device easily tipping over when measuring the leg circumference.

[0056] Based on any of the above schemes, the base 10 includes a support plate 11 and a support seat 12, one end of the support plate 11 is fixedly connected to the lower end of the main frame 100, and the other end of the support plate 11 is fixedly connected to the support seat 12.

[0057] There is a certain space between the support plate 11 and the support seat 12, so that when measuring the leg circumference, the feet of the person being measured can be placed in the space, making the legs closer to the entire device, and the patella part also fits better with the positioning device 200, making the positioning more accurate and the measurement data more accurate.

[0058] Specifically, an arc-shaped groove is provided on the side of the support plate 11 close to the measuring leg.

[0059] By providing the arc-shaped groove, when the leg approaches the leg circumference measuring device, a certain amount of avoidance space can be provided, so that the leg can fit the device more closely.

[0060] In one specific example, when measuring leg circumference, the person being measured places the foot of the leg being measured in the space formed by the support plate 11 and the support seat 12. According to the height of the person being measured, the patella positioning block 210 is first adjusted to a suitable position, and the patella positioning block 210 is locked and fixed by screwing the locking pin 40. Then, the patella of the person being measured is placed in the groove of the patella positioning block 210, and the upper ruler 300 is adjusted to 15 cm above the patella, and the lower ruler 400 is adjusted to 10 cm below the patella, that is, the upper ruler 300 is adjusted to 15 cm above the zero scale line of the position positioning ruler 220, and the lower ruler 400 is adjusted to 10 cm below the zero scale line of the position positioning ruler 220. Pull the measuring tape 500 inside the upper and lower rulers 300 and 400, circumscribing the leg measurement points. Then, snap the corresponding buckle 510 into the corresponding positioning hole 700. Press the push button 800 to further tighten the measuring tape 500, accurately measuring the leg circumference and recording the corresponding data. Once the measurement is complete, remove the buckle 510, and retract the measuring tape 500 through the window 600 back into the upper and lower rulers 300 and 400.
