The operation is very troublesome and the measurement efficiency is low. Therefore, in response to the above problems, we propose a new and easy-to-use device for measuring the circumference of the lower limb. Utility Model Content

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a convenient device for measuring the circumference of lower limbs, including a mounting shell 1, both sides of the outer surface of the mounting shell 1 are provided with a first sliding groove 11, the front surface of the mounting shell 1 is provided with a second sliding groove 12, an adjusting mechanism 3 is arranged inside the mounting shell 1, and measuring mechanisms 4 are symmetrically arranged on both sides of the adjusting mechanism 3, the adjusting mechanism 3 includes a sliding block 301, the front surface of the sliding block 301 is fixedly connected with a connecting column 302, the front end of the connecting column 302 is fixedly connected with a limiting disk 306, the outer surface of the connecting column 302 is slidably provided with an anti-skid disk 303 near the rear side, a spring 305 is fixedly connected between the outer surfaces of the anti-skid disk 303 and the limiting disk 306, the spring 305 is sleeved on the outside of the connecting column 302, and the sliding block 301 is slidably embedded in the mounting shell 1 , the outer surface of the connecting column 302 and the inner surface wall of the second sliding groove 12 are slidably fitted, the rear surface of the anti-slip plate 303 and the front surface of the mounting shell 1 are in conflict, and the outer surfaces of both sides of the mounting shell 1 are symmetrically fixedly connected with straps 2, the front surface of one strap 2 is symmetrically sewn with Velcro hook surfaces 21, and the rear surface of the other strap 2 is sewn with Velcro fur surface 22, the Velcro hook surface 21 and the Velcro fur surface 22 cooperate with each other, and the two measuring mechanisms 4 both include measuring belts 401, and the two measuring belts 401 are symmetrically fixedly connected to the outer surfaces of both sides of the sliding block 301, and the outer surfaces of the two measuring belts 401 are respectively slidably fitted with the inner surface walls of the two first sliding grooves 11, the front surface of the measuring belt 401 is provided with a second scale 404, and the outer surface of one side of the mounting shell 1 is provided with a first scale 13.

[0023] The effect achieved by the entire embodiment 1 is that when the device is in use, the mounting shell 1 is first placed at the patella position, and then the two straps 2 are tightened to surround the patient's lower limbs. The Velcro hook surface 21 and the Velcro fleece surface 22 play a role in fixing the device at the patella position. Then, after observing the first scale 13 on the side of the mounting shell 1, the limit plate 306 is pressed with the thumb, and then the anti-slip plate 303 is pulled backward with the index finger and middle finger to move it away from the mounting shell 1. After that, the sliding block 301 can be pulled upward through the limit plate 306 and the connecting column 302 to move up and down. When the sliding block 301 moves to 10cm and 15cm above the patella and 10cm and 15cm below the patella, Loosening the anti-skid plate 303 will cause the spring 305 to rebound. After the spring 305 rebounds, the anti-skid plate 303 will be pressed against the front surface of the mounting shell 1 to fix the position of the sliding block 301. Subsequently, the circumference of the lower limb can be measured by pulling the two measuring belts 401 backwards and surrounding the outside of the lower limb. The overall structure is simple and easy to operate, which can greatly improve the measurement efficiency of the circumference of the lower limb. The first sliding groove 11 is mainly used to avoid the measuring belt 401, and the first sliding groove 11 is opened on the side. The measuring belt 401 will not contact the patient's skin when sliding. The second scale 404 on the two measuring belts 401 is mainly used to view and read the measurement data.

[0024] Embodiment 2, as Figure 1-Figure 4 As shown, a thin steel sheet 402 is embedded in the two measuring strips 401 near the mounting shell 1 , a thin copper sheet 403 is embedded in the two measuring strips 401 away from the mounting shell 1 , and a warped edge 304 is provided at the edge of the anti-slip plate 303 .

[0025] The effect achieved by the entire embodiment 2 is that, by arranging the warped edge 304 on the edge of the anti-slip disk 303, it is convenient to use the middle finger and index finger to press the anti-slip disk 303, thereby improving the convenience of operation. The thin steel sheet 402 can bend and rebound forward and backward, and is difficult to bend up and down, so that the measuring tape 401 can remain horizontal during measurement, and the yield strength of the thin copper sheet 403 is relatively low, so the end of the measuring tape 401 is easier to shape during measurement, and the measuring tape 401 that is loosened after bending can read the scale according to the crease, and the measurement effect is improved by mutual cooperation.

[0026] Working principle: When using the device, first place the mounting shell 1 at the patella position, then tighten the two straps 2 to surround the patient's lower limbs, and then the Velcro hook surface 21 and the Velcro fleece surface 22 will fix the device at the patella position. Then, after observing the first scale 13 on the side of the mounting shell 1, press the limit plate 306 with the thumb, and then use the index finger and middle finger to pull the anti-slip plate 303 backward to move it away from the mounting shell 1. After that, the sliding block 301 can be pulled upward through the limit plate 306 and the connecting column 302 to move up and down. When the sliding block 301 moves to 10cm and 15cm above and 10cm and 15cm below the patella, the anti-slip plate 303 is released so that the spring 305 will rebound. After the spring 305 rebounds, the anti-slip plate 303 will be pressed against the front surface of the mounting shell 1 to fix the position of the sliding block 301. Then, the two measuring belts 401 are pulled backward and wrapped around the outside of the lower limb. The circumference of the lower limbs can be measured, the overall structure is simple, the operation is convenient, and the measurement efficiency of the circumference of the lower limbs can be greatly improved. The first sliding groove 11 is mainly used to avoid the measuring belt 401, and the first sliding groove 11 is opened on the side, the measuring belt 401 will not contact the patient's skin when sliding, and the second scales 404 on the two measuring belts 401 are mainly used to view and read the measurement data. In addition, by arranging the warped edge 304 on the edge of the anti-slip plate 303, it is convenient to use the middle finger and index finger to press the anti-slip plate 303, thereby improving the convenience of operation. The thin steel sheet 402 can bend and rebound back and forth, and it is difficult to bend up and down, so that the measuring belt 401 can be kept horizontal during measurement, and the yield strength of the thin copper sheet 403 is relatively low, so the end of the measuring belt 401 is easier to shape during measurement, and the measuring belt 401 that is loosened after bending can read the scale according to the crease, and the measurement effect is improved by mutual cooperation.
