Leg circumference measuring instrument

Abstract

The invention discloses a leg circumference measuring instrument comprising a clamping plate. The clamping plate is provided with a pushing device, the clamping plate is provided with an elastic curved plate, the lower end of the clamping plate is provided with a disc, a U-shaped hanging edge is fixedly hinged to the upper end surface of the disc, elastic clamping pieces are fixedly hinged above the edge of one side of the disc away from the clamping plate, and the elastic clamping pieces on the disc on both sides of the clamping plate are laterally symmetrical. A connection frame is fixedly connected to the front side of the intermediate position of the lower end surface of the disc, and the connection frame is transparent in the front and the rear. Ruler plates on two sides slide vertically and synchronously through a linkage rod, the force is applied in motor transmission, so that the ruler plates drive a leather measuring tape connected to move to the corresponding measuring positions. Under the condition that the stress of the fixed legs is consistent, the measuring positions of the two legs are ensured to be the same, and then the leather measuring tape is pulled out from a storage cylinder and wound around the leg by one circumference for measurement. During measurement, a stamp block at the end of the leather measuring tape marks the corresponding position of the leather measuring tape to facilitate recording.

Description

technical field [0001] The invention relates to the technical field of leg circumference measurement, in particular to a leg circumference measuring instrument. Background technique [0002] Leg circumference refers to the size of the human leg circumference. It is mainly divided into thigh circumference and calf circumference. It is one of the indicators of human body shape. It reflects the development level and degree of human leg muscles. measure the circumference; [0003] The disadvantage of the general leg circumference measurement device is that when the general leg circumference is measured, a simple leather tape measure is used to go around one leg for a week, then record the size, and then measure it around the other leg. When measuring two legs, there is no guarantee that the positions of the two measurements are the same or close to each other, which will lead to larger data errors.

Problems solved by technology

[0004] The object of the present invention is to provide a leg girth measuring instrument to solve the above-mentioned background technology. When measuring the general leg girth, a simple leather tape measure is used to go around one leg first, then record the size, and then go around the other leg. One leg is measured, but when the two legs are measured in this way, there is no guarantee that the positions of the two measurements are the same or close, which will lead to a problem of large data errors
