[0028] Embodiment 1

[0029] As Figures 1 - 4As shown in the figure, a leg circumference measuring device proposed by the present utility model includes: a bracket 1, an outer housing 2, a knob, a fixing column 4, and a marking component 5; the outer housing 2 is installed on the bracket 1; the knob 3 is installed on the outer housing 2; the fixing column 4 is installed on the outer housing 2; and the marking component 5 is installed on the fixing column 4; the marking component 5 includes an auxiliary piece 501, and a sponge sleeve 502 is installed on the auxiliary piece 501; the auxiliary piece 501 is provided with a fixing member; it is used to cooperate with the auxiliary piece 501 to mark the measurement data. By connecting the fixing column 4 and the marking component 5, the marking component 5 can cooperate with the measuring rope 403 for measurement operations, which is convenient for improving the use function of the leg circumference measuring device and facilitating its operation and measurement. At the same time, the sponge sleeve 502 is installed on the outer periphery of both sides of the auxiliary piece 501, and no fixing member is required for installation, which is convenient for the structural cooperation of the marking component 5 to be used.

[0030] Furthermore, the fixing column 4 is installed with a mounting shell 401, and a limiting shell 402 is installed inside the mounting shell 401. The limiting shell 402 is provided with two openings communicating with the outside, and a measuring rope 403 and an auxiliary piece 501 are respectively installed inside the openings. Both the measuring rope 403 and the auxiliary piece 501 are installed through the limiting shell 402, which is convenient for synchronously adjusting the positions through the fixing column 4 and facilitating the cooperation of the structures of the leg measuring device.

[0031] Furthermore, the measuring rope 403 and the auxiliary piece 501 have the same length; the measuring rope 403 and the auxiliary piece 501 synchronously adjust their positions with the fixing column 4 for measuring different positions of the leg. The auxiliary piece 501 is made of a sheet-like rope and is similar to a long strip-shaped rope structure such as a flat shoelace. Then, a long strip through hole is provided on the auxiliary piece 501 to cooperate with the fixing member to penetrate and clamp it for use, which is convenient for the structural cooperation of the marking component 5 and achieving marking according to the measurement of the measuring rope 403.

[0032] Furthermore, the fixing member includes a positioning buckle 503, a mounting hole 504, a mounting rod 505, and a connecting hole 506; the positioning buckle 503 is installed above the auxiliary piece 501, and the positioning buckle 503 is provided with a mounting hole 504; the connecting hole 506 penetrates through the auxiliary piece 501 and the mounting hole 504 and is rotatably connected, so that the mounting rod 505 is connected below the auxiliary piece 501. By providing threads on the inner wall of the mounting hole 504 and on the outer periphery of the mounting rod 505, the mounting rod 505 and the mounting hole 504 are rotatably connected, with simple operation and convenient use. Furthermore, multiple fixing members are provided to cooperate with the auxiliary piece 501 to mark the measurement data, which is convenient for marking different measurement data during the measurement operation, and then taking the average value to increase the measurement accuracy.

[0033] Further explanation: Constraint straps 6 are installed on both sides of the bracket 1, and the connection ends of the two constraint straps 6 are fixed by Velcro. First, the measuring device is roughly fixed on the leg by the constraint straps 6 to serve as a support point for the measuring device, and then the fixing plate 8 and the constraint rod 9 are fixed to facilitate increasing the usage modes of the leg measuring device.

[0034] Further explanation: A storage case 7 is installed on one side of the outer housing 2, and the storage case 7 is connected to a cover body through a hinge above it for storing fixing parts. The cover body is controlled by the hinge to open or close the storage case 7, facilitating the storage of the fixing parts therein. When the fixing parts are needed for use, they can be quickly taken out to improve the measuring efficiency.

[0035] Embodiment 2

[0036] As Figure 1 shown, a leg circumference measuring device proposed by the present utility model, on the basis of the above embodiments, this embodiment also details the specific components such as the outer housing 2 and the bracket 1, as well as the cooperation mode.

[0037] Further explanation: A sliding plate, a bidirectional lead screw and a guide rod are installed inside the outer housing 2; the knob 3 is rotationally connected to the guide rod through a rotating shaft and a bevel gear for adjusting the height of the fixing column 4. Furthermore, two bevel gears are provided to cooperate with the adjustment of the fixing column 4. By rotating the knob 3, the rotating shaft rotates, and the bidirectional lead screw rotates through the first bevel gear and the second bevel gear. Then, the sliding plate is adjusted to move towards or away from the port direction of the outer housing 2. After adjusting the position of the measuring rope 403, the upper and lower measuring ropes 403 are wound around the leg for one week and the scale is read. After repeated measurements, the average value of the statistical data is the relatively accurate leg circumference value. Furthermore, during one measuring operation, the marking assembly 5 is used to mark the measuring position, and then it is disassembled, so that the data can be recorded, facilitating the increase of the usage modes of the leg measuring device.

[0038] Further explanation: Fixing plates 8 are installed at both ends of the bracket 1, and constraint rods 9 are installed on the fixing plates 8 for fixing the measuring rope 403 on the leg. By inserting one end of the arc-shaped constraint rod 9 with a groove into the limiting groove, the arc-shaped constraint rod 9 squeezes the wedge blocks on both sides, causing the wedge blocks to compress the cylindrical spring. Then, according to the thickness of the leg, a groove at an appropriate position is selected, and the compressed cylindrical spring releases elastic potential energy, causing the wedge blocks on both sides to be clamped in the grooves on both sides of the arc-shaped constraint rod 9, so as to install the constraint rod 9 on the fixing plate 8 for use.

[0039] The working principle of the present utility model is as follows: First, place the leg measurer on one side of the leg and fix it with the restraint strap 6. Then, operate the fixing plate 8 and the restraint rod 9 to enhance the stability of the measurer. Use the measuring rope 403 to measure the leg. During the measurement with the measuring rope 403, simultaneously wind the auxiliary piece 501 around the leg. The auxiliary piece 501 marks the measurement points on the leg. Then, use the positioning buckle 503. There is a mounting hole 504 below the positioning buckle 503. The mounting hole 504 passes through the opening on the auxiliary piece 501 to connect the rotating and mounting rod 505. The mounting rod 505 is connected to the connecting hole 506. The mounting rod 505 rotates with the mounting hole 504 to clamp the positioning buckle 503 and the connecting hole 506 on the auxiliary piece 501, cooperating with the measuring rope 403 to measure the leg. Then, according to the data on the measuring rope 403, fix the fixing piece on the auxiliary piece 501. Then, disassemble the fixing plate 8, the restraint rod 9, and the restraint strap 6, take the leg measurer off the leg, straighten the measuring rope 403 and the auxiliary piece 501, confirm according to the position marked by the fixing piece on the auxiliary piece 501 and the scale of the measuring rope 403, and then record the measurement data.

[0040] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited thereto. Various changes can be made without departing from the gist of the present utility model within the scope of knowledge possessed by those skilled in the relevant technical field.
