The working principle of the arm circumference measuring tool 200 is as follows:
referring to fig. 1-3, the arm circumference measuring tool 200 includes a fixing plate 210, a connecting member 220, a measuring ruler 230 and a measuring band 240; the fixing plate 210 is an arc-shaped plate, the arc-shaped inner side surface of the fixing plate 210 is used for being attached to an arm of a person to be tested, and the fixing plate 210 is provided with a strip-shaped hole 211 along the central axis direction; the connecting piece 220 is connected with the fixing plate 210 and is used for connecting with the arm of the person to be tested so as to keep the fixing plate 210 and the arm of the person to be tested in a fit state;
and the measuring scale 230 includes a scale case 231, a coil spring, a tape 232, and a first connector 233; the tape case 231 is slidably coupled to the arc-shaped outer side surface of the fixing plate 210 in the central axis direction of the fixing plate 210; the coil spring is accommodated in the blade case 231; one end of the tape 232 is connected with a coil spring, and the other end of the tape 232 is connected with the first connector 233, and the coil spring is used for enabling the tape 232 to have a tendency of contracting towards the inside of the tape box 231; the measuring belt 240 comprises a belt body 241, a second connector 242 and a third connector 243; the second connector 242 and the third connector 243 are respectively connected to two ends of the belt body 241; the second connector 242 is sleeved on the tape 232, and the first connector 233 is used for abutting against the second connector 242 to limit the second connector 242 to be separated from the tape 232; the third connection head 243 is for detachable connection with the first connection head 233.
Therefore, in the using process of the arm circumference measuring tool 200, the fixing plate 210 can be kept in a state of being attached to the arm of the person to be measured through the connection of the connecting piece 220 and the arm of the person to be measured, so that the arm circumference of the person to be measured can be conveniently measured; in the measuring process, since the ruler box 231 is slidably connected with the fixing plate 210 and the second connector 242 is sleeved on the flexible ruler 232, the ruler box 231 can slide relative to the fixing plate 210 to adjust the position of the measuring ruler 230, so that the measuring ruler 230 can be adjusted to a proper arm circumference measuring position; in the measuring process, the first connector 233 is connected with the third connector 243, and the second connector 242 is sleeved on the tape 232, so that the arm surrounding the measured person can be formed in such a way to measure the arm circumference; in addition, in the process, under the action of the coil spring, a certain contraction force can be applied to the tape 232, so that the tape 232 and the belt body 241 surrounding the arm of the person to be measured can apply a certain tightening force to the arm of the person to be measured, the state that the tape 232 and the belt body 241 are attached to the arm of the person to be measured can be maintained, and the measuring precision can be improved.
In order to ensure the consistency of the positions measured by the measuring scale 230 during the measurement, the positions measured by the measuring scale 230 can be ensured by using the position of the fixing plate 210 and the bone position of the measured person as the base point of the position to be measured and the position at a certain distance from the base point as the measuring point of the measuring scale 230, so that the consistency of the positions measured by the measuring scale 230 can be ensured by adjusting the position of the measuring scale 230 in such a manner that the graduated scale 213 slides relative to the fixing plate 210 after the position of the fixing plate 210 clamped to the measured person is determined during the use of the arm circumference measuring tool 200. For example: the position which is flush with the elbow is used as a position base point through the fixing plate 210, and the position which is 10cm upwards measured by taking the elbow as a starting point is used as a measuring point of the measuring scale 230; then, in the process of performing the measurement, after the position of the fixed plate 210 is determined, the measuring scale 230 is slid with respect to the fixed plate 210 so as to be able to be slid to the position of the measuring point, and in the process, in order to measure the sliding distance of the measuring scale 230, thereby measuring the spaced distance between the measuring scale 230 and the end of the fixed plate 210, the arc-shaped outer side surface of the fixed plate 210 is provided with a scale 213, the scale 213 extends in the central axis direction of the fixed plate 210, and the scale 213 is used for measuring the sliding distance of the cartridge of the measuring scale 230 with respect to the bar-shaped hole 211.
Further, referring to fig. 1 to 3, in the present embodiment, when the second connector 242 is disposed, the second connector 242 is disposed with a through hole 244 through which the tape 232 passes, so that the second connector 242 is sleeved on the tape 232, and after the first connector 233 is connected to the third connector 243, the tape 232 is driven to contract by a contraction force of the coil spring, so that the second connector 242 slides relative to the tape 232 in a process of covering the arm shaft of the person to be measured by the tape 232, thereby tightening the tape body 241 and the tape 232.
Under this condition, in the process of sliding the measuring ruler 230, the second connecting head 242 is driven to move synchronously with the measuring ruler 230 to reduce the possibility of the belt 241 curling, so that the second connecting head 242 can be slidably engaged with the strip-shaped hole 211, and the second connecting head 242 is connected with the ruler box 231. Therefore, the measuring scale 230 can drive the second connecting head 242 to synchronously slide relative to the fixing plate 210 in the sliding process.
In addition, referring to fig. 1 to 3, when the first connecting head 233 and the second connecting head 242 are disposed, in order to prevent the first connecting head 233 from shrinking into the tape box 231, the first connecting head 233 may abut against the tape box 231 to prevent the first connecting head 233 from shrinking into the tape box 231 under the action of the coil spring, and in order to prevent the first connecting head 233 from moving to the arc-shaped outer side surface of the fixing plate 210 through the strip-shaped hole 211 under the action of the coil spring, one end of the second connecting head 242 facing the arc-shaped inner side surface of the fixing plate 210 is configured to abut against the first connecting head 233.

In order to improve the stability of the connection between the fixing plate 210 and the arm of the person to be measured, the connecting members 220 are connected to both ends of the fixing plate 210 along the central axis direction of the fixing plate 210. Specifically, when the connection member 220 is provided, the connection member 220 may include at least two arc-shaped clamping plates 221, the two arc-shaped clamping plates 221 are both connected to the fixing plate 210 and symmetrically disposed with respect to the central axis of the fixing plate 210, and the two arc-shaped clamping plates 221 are both used for clamping the arm of the person to be tested. Or, the connector 220 includes at least one elastic band, one end of which is connected to one side of the fixing plate 210 and the other end of which is detachably connected to the other side of the fixing plate 210.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
