[0025] in, Figure 3 yes Figure 2 Internal structure diagram. Figure 4 This is a schematic diagram of the structure used in this embodiment, as shown below. Figure 3 and Figure 4 As shown, the side wall of the housing 5 is provided with a first outlet. The first measuring tape assembly 1 includes a first measuring tape 11 that can extend from the first outlet for measuring the length of a patient's leg; the second measuring tape assembly 2 is tractively connected to the first measuring tape assembly 1 and is used to mark the position L / 2 when the extended length of the first measuring tape 11 is L; the third measuring tape assembly 3 is tractively connected to the first measuring tape assembly 1 or the second measuring tape assembly 2 and is used to mark the position L / 3 when the extended length of the first measuring tape 11 is L; the fourth measuring tape assembly 4 is tractively connected to the first measuring tape assembly 1, the second measuring tape assembly 2, or the third measuring tape assembly 3 and is used to mark the position 2L / 3 when the extended length of the first measuring tape 11 is L.

[0029] It is understood that when this embodiment is used for lymphedema measurement, in addition to the leg positioning measurement, it can also be used for positioning measurement of the upper limb or other positions.

[0030] like Figure 2-4 As shown, in this embodiment, the housing 5 is provided with a first outlet 51, a second outlet 52, a third outlet 53 and a fourth outlet 54 on its side wall.

[0031] Specifically, the first measuring tape assembly 1 in this embodiment also includes a first measuring tape box 10 and a first transmission assembly 13.

[0032] The first measuring tape box 10 is used to rewind the first measuring tape 11. Figure 5 This is a top view of the first measuring tape in this embodiment, as shown below. Figure 5 As shown, the surface of the first measuring tape 11 in this embodiment is provided with scale. Specifically, scale lines are provided on both sides of the first measuring tape 11, and the scale value is set in the middle of the two sets of scale lines.

[0035] The second measuring tape box 20 is provided with a second measuring tape 21 that can extend from the second outlet 52. The second measuring tape 21 is provided with a second rack 22. The second rack 22 is provided with a first pointer 23 pointing to the first measuring tape 11. The second rack 22 is a flexible rack that can be rolled up inside the second measuring tape box 20.

[0036] The second transmission assembly 24 includes a first auxiliary gear 241 and a first gear 242 for meshing with the second rack 22.

The transmission ratio between the main gear 131 and the first gear 242 is 2:1.

[0037] In this embodiment, the diameter of the first gear 242 is set to be twice the diameter of the main gear 131, and the number of teeth of the first gear 242 is also twice the number of teeth of the main gear 131. Thus, when the first rack 12 drives the main gear 131 to rotate, when the extension length of the first rack 12 is L, the extension length of the second rack 22 under the drive of the first auxiliary gear 241 and the first gear 242 is L / 2.

[0038] The third measuring tape assembly 3 in this embodiment includes a third measuring tape housing 30 and a third transmission assembly 34.

The third transmission assembly 34 includes a third gear, which is connected to the first shaft structure 132. The transmission ratio between the main gear 131 and the third gear is 3:1.

[0040] In this embodiment, the diameter of the main gear 131 is set to be three times the diameter of the third gear, and the number of teeth of the main gear 131 is also three times the number of teeth of the third gear. Thus, when the first rack 12 drives the main gear 131 to rotate, when the extension length of the first rack 12 is L, the third gear drives the third rack to extend by L / 3.

The fourth transmission assembly 44 includes a second auxiliary gear 441 and a fourth gear 442 for meshing with the fourth rack 42. The second auxiliary gear 441 has the same structure as the third gear, and the second auxiliary gear 441 meshes with the third gear and the fourth gear 442 respectively. The transmission ratio between the third gear and the fourth gear 442 is 2:1.

[0043] In this embodiment, the diameter of the fourth gear 442 is set to be twice the diameter of the third gear, and the number of teeth of the fourth gear 442 is also twice the number of teeth of the third gear. Thus, when the extension length of the third rack is L / 3, the extension length of the fourth rack is 2L / 3.

[0044] As an optional implementation, the first measuring tape box 10, the second measuring tape box 20, the third measuring tape box 30, and the fourth measuring tape box 40 are all equipped with ruler springs (not shown in the figure).

Furthermore, in this embodiment, a braking structure 50 for positioning the first measuring tape 11 is provided on the surface of the housing 5. The braking principle of the braking structure 50 is the same as that of the measuring tape and will not be described in detail here. By providing the braking structure 50 on the surface of the housing 5, the first measuring tape 11 can be fixedly positioned during measurement, avoiding the problem of inaccurate measurement.

[0045] As an optional implementation, the end of the first measuring tape 11 is provided with a stop end 111, and the end face of the stop end 111 is provided with a pull ring 112. In use, the first measuring tape 11 can be pulled out from the housing 5 through the pull ring 112 for easy use.

[0046] As an optional implementation, a support structure 6 is provided at the bottom of the housing 5, which can support the housing 5 above the patient's legs.

[0047] Specifically, the support structure 6 in this embodiment includes a first bracket 61 and a second bracket 62 that are respectively hinged to both sides of the bottom of the housing 5.

[0048] The support structure 6 includes a stowed state and an unfolded state, so as to facilitate storage and use.

[0049] When stowed, the support structure 6 can be placed in the groove provided at the bottom of the housing 5; Figure 7 This is a schematic diagram of the structure after the support structure is unfolded in this embodiment, as shown below. Figure 7 As shown, in the unfolded state, the first support 61 and the second support 62 form an "eight" shape, with the patient's legs placed inside the "eight" shape, and the patient's legs are positioned and measured from above by marker points.
