Embodiment 1

[0045] See Figure 7 to Figure 10 As shown, a human body multidimensional joint range of motion measurement meter 10 of an embodiment is shown, which includes a measurement meter housing, and the measurement meter housing includes a glass 12, a dial 13, a bottom shell 14 and a side shell 11, and the glass 12 1. The dial 13 and the bottom case 14 are sequentially installed in the side case 11, the driving part 20 is between the bottom case 14 and the dial 13, and the pointer part 30 is between the glass 12 and the dial 13;

[0046] The driving part 20 is installed on the back of the dial 13. The driving part 20 includes a gravity hammer 21, a driving wheel 22, a first driven wheel 23, a second driven wheel 24, a damping wheel 25 and a gravity hammer driving wheel 26. The driving wheel 22 is installed on the dial 13 and the axis 221 of the driving wheel 22 coincides with the center of circle of the dial 13, the driving wheel 22 meshes with the first driven wheel 23, the first dr...

Embodiment 2

[0087] In this embodiment, the basic structure of the measuring meter is the same as that in Embodiment 1, the only difference is that in this embodiment, only two gear meshing structures are used to achieve the same technical effect as in Embodiment 1. Specifically, in this embodiment, what is installed on the back of the dial 13 is a driving wheel 42, a driven wheel 43, a bracket 44 and a gravity hammer 41. The gravity hammer 41 is connected with the driven wheel 43 through the bracket 44, and the driven wheel 43 is engaged with the driving wheel 42. When the gravity hammer 41 is facing such as Figure 16 When moving in the direction of middle B, the driven wheel 43 rotates counterclockwise, and the driving wheel 42 meshed with the driven wheel 43 rotates clockwise, that is, the measuring pointer connected to the driving wheel 42 rotates to the right, and the direction of the measuring pointer is consistent with the direction of the gravity hammer 41 unanimous. In this embo...

Embodiment 3

[0094] like Figure 17 As shown, in the present embodiment, all the gear mechanisms of the first embodiment are canceled for the measuring table. This alternative solution cancels the memory pointer mechanism of Embodiment 1. The scheme of this embodiment retains the left and right measurement mode of Embodiment 1, and improves it to a left and right 0°-360° full-circle rotation mode, and adds left and right 180°-360° numerical labels. The principle of the gravity hammer in Embodiment 1 is retained, replaced by the integration of the pointer rod, the pointer rod passing through the horizontal bar, the pointer rod behind the disk, and the weight hammer, and the middle part of the pointer rod (the pointer rod passing through the Pan crossbar) passes through the table center hollow tube; the pointer rod, the cross-pan cross bar, and the pointer rod behind the disc are respectively opposite vertical and parallel on a plane. The rear end of the pointer rod is connected with a hea...

Abstract

The invention discloses a human multidimensional joint motion range measuring instrument and an operating principle thereof in the technical scheme. The human multidimensional joint motion range measuring instrument comprises a measuring instrument shell with a drive part and a pointer part, wherein the drive part comprises a gravity hammer, a driving wheel, a first driven wheel, a second driven wheel, a damping wheel and a gravity hammer drive wheel, and due to a meshing transmission relation between gears, the driving wheel and the gravity hammer drive wheel have the consistent rotating direction; the pointer part comprises a pointer axis, a measuring pointer, a left memory pointer, a right memory pointer and a zeroing handle; and damping washers are arranged among the pointers. According to the technical scheme of the invention, with the adoption of a gravity hammer drive structure, a swing direction of the gravity hammer is consistent with a limb measurement direction; and due to the meshed relation between the gears, the swing direction of the measuring pointer is consistent with the swing direction of the gravity hammer after the driving wheel rotates. Due to use of the damping wheel, damping is produced during measurement, the conditions that the pointer does not swing at an over-speed and moves at a constant speed and does not oscillate back and forth at the endpoint inthe rotating process are guaranteed, and the measuring stability and accuracy are ensured.

Description

technical field [0001] The invention relates to the technical field of measuring meters, in particular to a human body multi-dimensional joint range of motion measuring meter and its working principle. Background technique [0002] like figure 1 As shown in A1-A4, most of the existing human body joint protractors 1000 are made of metal or organic materials; they are mainly composed of a fixed arm 100, a movable arm 200 and a dial 300, with the center of the dial 300 as the axis, and most of the dials are Sector disk, or semi-circular disk. [0003] like Figure 2-6 As shown, when measuring, hold the fixed arm 100 and the movable arm 200 of the goniometer with two hands respectively, align the central axis 400 of the goniometer with the joint of the part to be measured, the fixed arm coincides with the end of the fixed limb, and the movable arm Align the coincidence of the moving limbs, measure the active range of motion (AROM), and obtain the measured value through the po...
