Description

Technical Field

[0001] The utility model relates to the technical field of leg circumference measurement, in particular to a calf circumference measuring tool. Background Art

[0002] When measuring leg circumference, a soft tape measure is usually used because the leg is similar to a cylinder. The tape measure is wrapped around the leg and the leg circumference data is obtained by reading the scale on the tape measure. However, due to uneven muscle distribution in the legs, especially the calves, the leg circumference of different parts of the calf varies. When measuring, the measurer needs to put the tape measure on different parts of the calf one by one to measure and record the data of each part of the calf, which is a cumbersome and inconvenient process.

[0003] Generally speaking, there are more muscles in the calf area, and the contraction and relaxation of the muscles will cause changes in the calf circumference. When the calf muscles contract, such as when walking, running or doing other activities that require the use of the calf muscles, the muscles will become tighter, which will cause the leg circumference to increase slightly. On the contrary, when the muscles relax, the leg circumference will decrease, and this change in leg circumference is more obvious in some people with well-developed calf muscles, such as cyclists. In general, when the person being measured controls the contraction or relaxation of the muscles, it is necessary to manually tighten the tape measure to measure and record the leg circumference change data, which is more inconvenient. Utility Model Content

[0004] The purpose of the present invention is to provide a calf circumference measuring tool to solve the problems raised in the above background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A calf circumference measuring tool, comprising:

[0007] A drawstring, a plurality of measuring mechanisms and a plurality of pulling mechanisms, wherein the plurality of pulling mechanisms correspond one to one with the plurality of measuring mechanisms, and the middle portion of one side of the plurality of measuring mechanisms is fixedly connected to one side of the drawstring;

[0008] The measuring mechanism includes a tape measure, and the middle part of one side of the tape measure is fixedly connected to one side of the drawstring, one end of the tape measure is fixedly connected to a connecting frame, and multiple pulling mechanisms are fixedly connected to the other side of the tape measure on the corresponding measuring mechanism.

[0009] Furthermore, one end of the drawstring is provided with an adhesive tape, and a measuring mechanism is located at the other end of the drawstring.

[0010] Furthermore, one measuring mechanism is equipped with two paper boards, and the top surfaces of the two paper boards are each provided with two cutouts, and the measuring tape on one measuring mechanism passes through the four cutouts in sequence.

[0011] Furthermore, the pulling mechanism includes:

[0012] A connecting shell, an elastic band and a connecting sticker, wherein the bottom surface of the connecting shell is fixedly connected to the other side of the adjacent measuring tape, one end of the elastic band is fixedly connected to one end inside the connecting shell, one side of the connecting sticker is fixedly bonded to the other end of the elastic band, and one side of the connecting sticker is fixedly bonded to one side of the adjacent measuring tape.

[0013] Furthermore, one side of each of the plurality of measuring tapes is fixedly bonded with a positioning sticker, and each of the plurality of positioning stickers is in contact with adjacent connection frames.

[0014] Furthermore, the connecting shell is made of rubber.

[0015] Furthermore, any positioning sticker is a double-sided adhesive sticker.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The invention provides a method for measuring the leg of a person's leg by clamping a measuring tape around the ankle, straightening the drawstring and fixing the other end of the drawstring near the knee of the calf with adhesive tape, and then passing the other ends of the measuring tapes on multiple measuring mechanisms through adjacent connecting frames so that the measuring tapes form loops and are wrapped around various parts of the calf. The connecting frames are attached to the calf with positioning stickers, and then the other ends of the measuring tapes are pulled so that the loops formed by the measuring tapes shrink and are tightly clamped around the calf. The other ends of the elastic bands are fixed to the surfaces of adjacent measuring tapes with connecting stickers. When the calf muscle state changes, the calf circumference will change. When the calf circumference increases, the measuring tapes will be stretched to form loops, and the other ends of the measuring tapes will pull the elastic bands. When the calf circumference decreases, the other ends of the measuring tapes will be pulled by the elastic bands, thereby tightening the measuring tapes. The calf circumference can be measured by observing the scales of the measuring tapes on the connecting frames, so that the calf circumference of various parts of the calf can be measured simultaneously and the calf circumference when the calf circumference changes can be automatically measured.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figures 1 to 4 In an embodiment of the present invention, a calf circumference measuring tool includes a drawstring 100, a plurality of measuring mechanisms 200, and a plurality of pulling mechanisms 400, wherein the plurality of pulling mechanisms 400 correspond one to one with the plurality of measuring mechanisms 200, and the middle portion of one side of the plurality of measuring mechanisms 200 is fixedly connected to one side of the drawstring 100;

[0025] The measuring mechanism 200 includes a tape measure 210 , and the middle part of one side of the tape measure 210 is fixedly connected to one side of the drawstring 100 . One end of the tape measure 210 is fixedly connected to a connecting frame 220 , and multiple pulling mechanisms 400 are all fixedly connected to the other side of the tape measure 210 on the corresponding measuring mechanism 200 .

[0026] Specifically, the tape measures 210 on the multiple measuring mechanisms 200 are all perpendicular to the drawstring 100. By clamping one measuring mechanism 200 at the ankle, the drawstring 100 can be straightened so that the other measuring mechanisms 200 are located at various parts of the calf in turn. The connecting frame 220 on the tape measure 210 is located at the zero scale of the tape measure 210. The user can then pass the other ends of the multiple tape measures 210 through the connecting frame 220 at one end, and then pull the other ends of the multiple tape measures 210 to clamp the multiple tape measures 210 at various parts of the calf. The user can then measure the leg circumference of the calf at various parts by looking at the scale of the tape measure 210 at the connecting frame 220, thereby measuring the leg circumference of the calf at various parts at the same time, which is convenient for the user to measure the leg circumference of the calf.

[0027] Example 1

[0028] like Figure 1-2 As shown, in this embodiment, a tape 110 is provided at one end of the drawstring 100, a measuring mechanism 200 is located at the other end of the drawstring 100, and one measuring mechanism 200 is equipped with two cardboards 300, and two cutouts 301 are provided on the top surfaces of the two cardboards 300, and the tape measure 210 on one measuring mechanism 200 passes through the four cutouts 301 in sequence.

[0029] In this embodiment, when a measuring mechanism 200 is clamped around the ankle for fixation, two cardboards 300 can be slid on adjacent tape measures 210 so that the two cardboards 300 are attached to the inner and outer ankles of the user. The surface of the cardboards 300 is relatively rough to increase the friction with the skin surface. The user can straighten the drawstring 100 and then use the tape 110 to stick the other end of the drawstring 100 to the calf near the knee to fix the drawstring 100, so that the user can measure the calf circumference.

[0030] like Figure 3-4 As shown, in this embodiment, the pulling mechanism 400 includes:

[0031] The connecting shell 410, the elastic band 420 and the connecting sticker 430, the bottom surface of the connecting shell 410 is fixedly connected to the other side of the adjacent tape measure 210, one end of the elastic band 420 is fixedly connected to one end inside the connecting shell 410, one side of the connecting sticker 430 is fixedly bonded to the other end of the elastic band 420, and one side of the connecting sticker 430 is fixedly bonded to one side of the adjacent tape measure 210.

[0032] In a specific implementation, after the other end of the tape measure 210 passes through the adjacent connecting frame 220 to form a loop, the other end of the tape measure 210 can be pulled to tighten the tape measure 210 around the calf for measurement, and then the other end of the elastic band 420 can be adhered to the connecting sticker 430, and then the other end of the elastic band 420 can be adhered to the tape measure 210 using the connecting sticker 430, and the other end of the elastic band 420 should be adhered to the part of the tape measure 210 where the loop is not formed. Then the user can perform human activities, and when the calf muscles change, The calf circumference will change at different parts of the calf, especially where the calf muscles are more. When the muscles contract, the calf circumference increases, thereby stretching the tape measure 210 around the calf, causing the other end of the adjacent elastic band 420 to be pulled toward the adjacent connecting frame 220. At this time, other people can measure the leg circumference by observing the scale of the tape measure 210. When the muscles relax, the calf circumference decreases, and the tape measure 210 will be pulled by the elasticity of the adjacent elastic band 420 to tighten the tape measure 210. Then, the leg circumference can be measured again by observing the scale of the tape measure 210.

[0033] Example 2

[0034] On the basis of the first embodiment, a positioning sticker 440 is provided to prevent the tape measure 210 from shifting.

[0035] like Figure 3 As shown, in this embodiment, a positioning sticker 440 is fixedly adhered to one side of multiple measuring tapes 210, and multiple positioning stickers 440 are in contact with adjacent connecting frames 220, and the connecting shell 410 is made of rubber; any positioning sticker 440 is a double-sided adhesive sticker.

[0036] During specific implementation, the positioning sticker 440 is a double-sided adhesive sticker, one side of which can be attached to the adjacent tape measure 210 and the other side can be attached to the human skin, so that the positioning sticker 440 is used to assist in fixing the positions of multiple tape measures 210 on the calf, and the positioning sticker 440 is used to fix the adjacent connecting frames 220 to the calf. When the calf muscles relax after contraction, the calf circumference first increases and then decreases. At this time, the elastic band 420 on the pulling mechanism 400 will pull the other end of the adjacent tape measure 210 to move due to the elastic force, and by fixing the position of the connecting frame 220, the elastic band 420 can facilitate the contraction of the loop formed by pulling the tape measure 210. The connecting shell 410 is made of rubber material, so that when the tape measure 210 bends, the connecting shell 210 can bend synchronously with it.

[0037] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0038] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
