Therefore, it should not be understood as a limitation on the present invention.

[0026] Furthermore, the terms “first”, “second”, and “third” are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0027] Example 1

[0028] like Figures 1 to 3 As shown, the upper limb operation force testing device in the embodiment of the present invention comprises a pedal assembly 2, a first bracket 1, a second bracket 3 and a base plate 4. The pedal assembly 2 is a horizontally arranged plate-like structure, which is used for the person to be tested to stand, the first bracket 1 is fixed to one side of the pedal assembly 2, the second bracket 3 is fixed to the other side of the pedal assembly 2 and is arranged opposite to the first bracket 1, the second bracket 3 is used to fix the waist area of ​​the person to be tested, and the base plate 4 is installed and fixed with a multifunctional force measuring device; the first bracket 1 is provided with a plurality of adjustment positions, and the plurality of adjustment positions are spaced apart in the height direction, and the base plate 4 can be detachably installed on any of the adjustment positions.

[0029] It can be understood that when the person to be measured stands on the horizontally arranged pedal assembly 2, since the height conditions of each person to be measured are different, the substrate 4 is installed and fixed on the first bracket 1 at an adjustment position matching the height conditions of the person to be measured, so that the multifunctional dynamometer on the substrate 4 can be correctly held by the person to be measured, and then the multifunctional dynamometer can accurately obtain the dynamometer data of the person to be measured, thereby improving the convenience of the correction position operation of the multifunctional dynamometer.

[0030] Specifically, if Figure 1 to Figure 2As shown, in the embodiment of the present invention, the first bracket 1 includes a base 12 and an adjustment rail 11. The base 12 is a rod-shaped structure, which is horizontally arranged and the right end of the base 12 is fixedly connected to the left side of the pedal assembly 2; the adjustment rail 11 is vertically arranged and the lower end of the adjustment rail 11 is fixedly connected to the left end of the base 12, and the lower end of the adjustment rail 11 and the left end of the base 12 are reinforced and connected by two first reinforcing ribs 13. A plurality of adjustment positions are spaced apart along the length direction of the adjustment rail 11, and a position number corresponding to each adjustment position is provided on the adjustment rail 11. In this way, it is convenient for the person to be measured to quickly install and adjust according to the position number and the position matching relationship between the multifunctional dynamometer and the person to be measured.

[0031] like Figure 1 As shown, in the embodiment of the present invention, a rib plate 41 and a first pin 42 are provided on the base plate 4, the rib plate 41 and the multifunctional force gauge are respectively located on both sides of the base plate 4, and a first through hole (not shown in the figure) is provided on the rib plate 41; the adjustment rail 11 has a strip groove 112, and the adjustment position is a first positioning hole 111 formed on the strip groove 112, and the first pin 42 passes through the first positioning hole 111 and the first through hole to fix the base plate 4 on the adjustment rail 11.

[0032] It can be understood that the rib plate 41 is arranged at the back center of the base plate 4, and the multifunctional dynamometer includes two push-pull force dynamometers and one rotation force dynamometer, all of which are installed on the front of the base plate 4. When the multifunctional dynamometer is adjusted in position, the first pin 42 is pulled out, and the rib plate 41 on the base plate 4 slides up and down in the strip groove 112 structure of the adjustment rail 11 to a suitable position to align the through hole on the rib plate 41 with the first positioning hole 111 on the adjustment rail 11, and the first pin 42 is inserted to fix the base plate 4 to complete the position adjustment of the multifunctional dynamometer.

[0033] Compared with the traditional adjustment method of disassembling the force measuring device, the force measuring device of this embodiment does not need to disassemble the multifunctional force measuring device itself, which improves the convenience of position adjustment of the force measuring device as a whole.

[0034] like Figure 2As shown, the multifunctional dynamometer in the embodiment of the present invention includes two push-pull force dynamometers and one rotational force dynamometer. The push-pull force dynamometer and the rotational force dynamometer are both mounted on the same side surface of the substrate 4. The rotational force dynamometer is located in the middle area of ​​the substrate 4, and the two push-pull force dynamometers are symmetrically distributed on both sides of the rotational force dynamometer. Among them, each push-pull force dynamometer 5 includes a handle 51, a first fixed seat 52, and a first force sensor located in the first fixed seat 52. The first fixed seat 52 is detachably fixed to the preset mounting hole on the surface of the substrate 4 by bolts. The first force sensor is used to obtain the force data of the handle 51 in the push-pull state on the first fixed seat 52. The rotational force dynamometer 6 includes a cross-shaped handle 61, a second fixed seat 62, and a second force sensor in the second fixed seat 62. The second force sensor is used to obtain the force data of the cross-shaped handle 61 in the rotation state on the second fixed seat 62. It should be noted that, according to actual applications, the cross-shaped handle 61 can also be replaced by a T-shaped structure handle, a straight structure handle structure, or a wheel handle structure.

[0035] It can be understood that the multifunctional dynamometer installed on the base plate 4 can simultaneously provide the person being tested with upper limb pushing and pulling force, double-arm rotation force, single-arm rotation force, handwheel rotation force and other operating forces to meet different types of force measurement requirements.

[0036] like Figure 1 and Figure 3 As shown, in the embodiment of the present invention, the second bracket 3 includes a support rod 31, an arc rod 32 and a first fastening belt 321. The support rod 31 is vertically arranged and the lower end of the support rod 31 is fixedly connected to the pedal assembly 2, and the support rod 31 and the pedal assembly 2 are reinforced by two second reinforcing ribs 33; the arc rod 32 is horizontally arranged and the arc rod 32 is fixed to the upper end of the support rod 31 and fits with the waist of the person to be measured in an embracing shape; the two ends of the first fastening belt 321 are respectively buckled and connected with the two ends of the arc rod 32 to bind the waist of the person to be measured.

[0037] It can be understood that when the person to be measured performs the force measurement operation, the waist of the person to be measured is bound to the support rod 31 by the first fastening belt 321, so as to avoid serious posture position deviation between the person to be measured and the multifunctional force gauge during the process of the person to be measured applying force, and ensure the readiness and repeatability of the multifunctional force gauge to obtain the force data of the person to be measured.

[0038] When the person to be tested performs force measurement on the upper limbs, the person to be tested steps on the pedal assembly 2 facing the front of the base plate 4. According to the height of the person to be tested, the base plate 4 is adjusted to a suitable height on the first bracket 1 and fixed to ensure that the person to be tested holds the multifunctional dynamometer correctly. The waist of the person to be tested leans on the arc rod 32 and is bound to the second bracket 3 through the first fastening belt 321. The person to be tested can perform strength testing on the upper limbs by operating the push-pull force dynamometer or the rotational force dynamometer with one hand, or can perform strength testing on the upper limbs by holding the handles with both hands, thereby achieving different types of strength tests in the same body position.

[0039] Example 2

[0040] like Figures 4 to 5 As shown, the main difference between the embodiment of the present invention and embodiment 1 is that the adjustment rail 11 of the first bracket 1 in the test device of the embodiment of the present invention includes an integrally arranged vertical section 11b and an arc section 11a, the lower end of the vertical section 11b is fixedly connected to the left end of the base 12, the arc section 11a is located at the upper end of the vertical section 11b, and the base plate 4 is installed on the arc section 11a for adjusting the angle of the upper limb of the person to be tested holding the multifunctional dynamometer.

[0041] When the upper limbs of the person being tested are tested at different angles, such as Figure 4 As shown, when the base plate 4 is at the highest position at the top of the arc segment 11a, the upper limbs of the person to be tested are raised to perform strength testing. In addition, the pedal assembly 2 is provided with a second fastening belt 21 for fixing the feet of the person to be tested, so as to prevent the feet of the person to be tested who is too light from being separated from the pedal assembly 2, and to ensure the stability of the body position of the person to be tested during the tensile force measurement.

[0042] like Figure 5 As shown, the test device of the embodiment of the present invention further includes a shoulder bracket 7 for fixing the shoulder area of ​​the person to be tested, and the shoulder bracket 7 is installed on the support rod 31 of the second bracket 3. Specifically, the shoulder bracket 7 includes an adjustment rod 71 and two shoulder supports 72 fixed at one end of the adjustment rod 71 and a second pin 712. The adjustment rod 71 is movably plugged with the support rod 31. A plurality of second positioning holes 711 are spaced apart in the length direction of the adjustment rod 71. A second through hole (not shown in the figure) is provided on the support rod 31. The second pin 712 passes through the second positioning hole 711 and the second through hole to fix the shoulder bracket 7. The shoulder support 72 is an arc-shaped structure.

[0043] It is understandable that the adjustment rod 71 is fixed to a suitable position of the support rod 31 according to the different heights of the person to be measured so that the shoulder support 72 can be engaged with the shoulder of the person to be measured.

[0044] Taking the surface of the pedal assembly 2 as the reference plane, when the user's upper limbs are tested at different angles, such as raising the user's upper limbs to 30, 45 or 60 degrees, the shoulder support 7 can fix the person to be tested in a suitable position to prevent the person's body from deviating from the test position during the strength test, thereby ensuring the stability of the person's upper body position.

[0045] In addition, if Figure 5 As shown, in the embodiment of the present invention, a tubular structure 713 is provided at the upper end of the adjustment rod 71, and the tubular structure 713 is horizontally arranged. The movable end of each shoulder support 72 is an insertion rod structure, and the insertion rod structure is movably inserted at both ends of the tubular structure 713 to adjust the interval between the two shoulder supports 72, thereby adapting to the shoulder width of different people to be tested and meeting the usage needs of different people to be tested.

[0046] It should be noted that the testing device can also be used in a weightless environment, such as for in-orbit strength testing of astronauts, to meet the astronauts' need to adjust the strength of their upper limbs at different angles in a weightless environment, thus expanding the application scope of the testing device.

[0047] The other structures of this embodiment are exactly the same as those of Embodiment 1, and thus will not be described in detail here.

[0048] The above are merely embodiments of the present invention and are not intended to limit the present invention.
