Description
Technical Field
[0001] This utility model relates to the field of body circumference measurement technology, and in particular to a measuring tape that facilitates the measurement of body circumference. Background Technology
[0002] Currently, the commonly used method for measuring waist circumference in my country is to measure it at a horizontal plane 1 cm above the navel.
[0003] When measuring waist circumference, first place the measuring tape on the subject's waist, with the tape measure tip positioned 1 cm above the subject's navel. The subject should stand upright with feet 25-30 cm apart. Pull the tape measure tip fixed to the support to wrap around the waist. Adjust the tape measure so that it is positioned 1 cm above the subject's navel, parallel to the ground, and close to the skin without pressing on it. Finally, read the measurement. The same method can be used to measure hip circumference.
[0004] In existing technologies, during measurement, it is necessary to simultaneously control the height and angle of the measuring tape, as well as the distance between the measuring tape and the navel. This can easily lead to abnormal measurement data due to the measuring tape becoming loose during the measurement process, resulting in inaccurate measurement data. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a measuring tape that is convenient for measuring body circumference, so as to solve the technical problems mentioned in the background art.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0007] A measuring tape for easy measurement of body circumference includes a base plate, a fixed cylinder at the top of the base plate, a sliding structure inside the fixed cylinder, and a sliding groove on the outer peripheral wall of the fixed cylinder.
[0008] The sliding structure includes a guide rod, which is rotatably disposed inside the fixed cylinder and has a threaded groove on its outer peripheral wall. A sliding sleeve is slidably disposed on the outer peripheral wall of the guide rod. A positioning frame is fixedly installed on the side wall of the sliding sleeve and inserted into the sliding groove. A sliding groove is provided on the outer wall of the sliding sleeve, and a pull rod is disposed inside the sliding groove. A threaded plate that is threadedly engaged with the threaded groove is provided at one end of the pull rod inserted into the sliding groove.

[0011] Furthermore, the pull rod extends into the interior of the positioning frame, and a hand pull hole is provided inside the pull rod.
[0012] Furthermore, the measuring structure includes a storage tube, inside which a measuring tape is wound up, and at the bottom end of the storage tube is a winding groove. A positioning knot is fixedly installed on the outer peripheral wall of the storage tube one centimeter below the winding groove.
[0013] Furthermore, the top of the fixed cylinder is rotatably provided with an adjustment disc, the bottom of the adjustment disc is provided with a square-headed insertion rod, and the top of the guide rod is provided with a square-headed hole, which cooperates with the square-headed insertion rod.
[0014] Furthermore, the side wall of the base plate is provided with an extension plate, and the upper end of the extension plate is provided with a positioning foot pedal.
[0015] In summary, this utility model has at least one of the following beneficial technical effects:
[0016] 1. This is a flexible measuring tape for easy measurement of body circumference. By hooking the pull rod with a finger, the pull rod moves outward, at which point the threaded plate separates from the threaded groove. Then, the positioning frame is directly pushed, causing the sliding sleeve to slide inside the guide rod to adjust the position of the positioning frame to the navel position of the person being measured. Then, the pull rod is released, and the threaded plate and threaded groove engage to fix the sliding sleeve. Rotating the guide rod, with the engagement of the threaded groove, lifts the fixed sleeve upward through the threaded plate, thus aligning the position of the measuring structure with the navel of the person being measured. This allows the device to quickly correspond to the measurements of people of different heights, effectively improving measurement efficiency.
[0017] 2. This is a flexible measuring tape for easy measurement of body circumference. The person being measured stands on the top of the base plate, facing the fixed cylinder. The sliding structure is dragged and moved inside the fixed cylinder, causing the positioning frame to quickly move to the position corresponding to the navel of the person being measured. The guide rod is rotated to finely adjust the position of the positioning frame so that the measuring structure is aligned with the navel of the person being measured. At this time, the person being measured pulls the measuring tape inside the measuring structure to wrap around themselves to achieve the purpose of measuring body circumference. The person being measured only needs to ensure that the measuring tape is parallel to the ground to complete the measurement, which can effectively improve the measurement accuracy.
