The lifting seat 20 is provided with a lifting groove, which extends along a second lateral direction perpendicular to the first lateral direction; the driving assembly 30 includes a first driving member 31 and a second driving member 32, both of which are arranged on the bracket 10, the first driving member 31 can drive the lifting seat 20 to move vertically, and the second driving member 32 can drive the lifting seat 20 to move along the first lateral direction.
[0032] By applying the technical solution of the present invention, the hip joint range of motion test device includes a bracket 10, a lifting seat 20 and a driving assembly 30. The person being tested stands on the bracket 10, places the legs of the person being tested in the lifting groove of the lifting seat 20, drives the lifting seat 20 to move vertically by the first driving member 31, and drives the lifting seat 20 to move along the first lateral direction by the second driving member 32, so as to test the hip joint range of motion of the person being tested. Compared with the testing device in the related art, there is no need to fix the human body and legs, the testing process is simple, and the practicability is high.
[0033] The bracket 10 is provided with armrests, and the two armrests are respectively located on both sides of the supporting seat 20 .
[0034] Specifically, the bracket 10 includes a base and a gantry disposed on the base.
[0035] like Figure 1 and Figure 4As shown, the hip joint range of motion test device further includes a transmission assembly 40, the transmission assembly 40 includes a transmission seat 41, the first driving member 31 can drive the transmission seat 41 to move vertically, and the second driving member 32 and the lifting seat 20 are both arranged on the transmission seat 41. The transmission seat 41 can drive the lifting seat 20 to move vertically on the one hand, and can arrange the second driving member 32 on the other hand, which has the advantages of simple structure and high reliability.
[0036] In this embodiment, the transmission seat 41 is disposed on the bracket 10 .
[0037] like Figure 6 As shown, the transmission assembly 40 further includes a transmission shaft 42, the transmission shaft 42 extends along the first transverse direction, the second driving member 32 can drive the transmission shaft 42 to rotate around its own axis, and the transmission shaft 42 can drive the lifting seat 20 to move along the first transverse direction. With the above structure, the rotational motion of the transmission shaft 42 can be converted into the linear motion of the lifting seat 20, which has the advantages of simple structure and high reliability.
[0038] A bearing is disposed on the transmission seat 41 , and the bearing is used to support the transmission shaft 42 and prevent the transmission shaft 42 from moving along the first transverse direction.
[0039] like Figure 4 and Figure 6 As shown, the transmission seat 41 has a receiving cavity and a strip-shaped hole communicating with the receiving cavity, the transmission shaft 42 is arranged in the receiving cavity, the lifting seat 20 is arranged on the transmission shaft 42 and is threadedly connected with the transmission shaft 42, and the lifting seat 20 passes through the transmission seat 41 through the strip-shaped hole. With the above arrangement, the transmission shaft 42 can be arranged in the internal space of the transmission seat 41, and the rotational motion of the transmission shaft 42 can be converted into the linear motion of the lifting seat 20 through the threaded fit.
[0040] In this embodiment, the lifting seat 20 includes a connected slider and a seat body. The slider is sleeved on the transmission shaft 42 and threadedly connected to the transmission shaft. The slider passes through the transmission seat 41 through a strip hole, and a lifting groove is set on the lifting seat 20.
[0041] like Figure 4 and Figure 5 As shown, the transmission assembly 40 also includes a driving shaft 43, and the second driving member 32 is a handle sleeved on the driving shaft 43, and the driving shaft 43 is connected to the transmission shaft 42 through gear transmission. With the above structure, by operating the handle, the driving shaft 43 can be rotated around its own axis, and then the transmission shaft 42 is driven to rotate through gear transmission.
[0042] In this embodiment, the drive shaft 43 extends vertically and is vertically penetrated on the transmission seat 41 with its upper end exposed. The drive shaft 43 and the transmission shaft 42 are driven by a bevel gear.

[0046] Specifically, when the hip joint range of motion is tested, the pawl 51 is rotated to disengage from the anti-rotation groove, and the pawl 51 can drive the pressing plate 52 to rotate, thereby losing the anti-rotation effect on the drive shaft 43. By operating the handle, the drive shaft 43 can be rotated to move the lifting seat 20. After the pawl 51 is released, the pressing plate 52 can be pressed against the pawl 51 under the action of the spring, so that the pawl 51 is inserted into one of the anti-rotation grooves.

The limiting shaft 44 can be used to limit the lifting seat 20 and guide the lifting seat 20, so that the lifting seat 20 can only move along the first transverse direction and cannot rotate.
[0048] In this embodiment, a limit seat is provided on the outer wall of the transmission seat 41 , and both ends of the limit shaft 44 are inserted in the limit seat. There are two limit shafts 44 , which are arranged vertically at intervals, and are both inserted in the lifting seat 20 .
[0049] like Figure 1As shown, the first driving member 31 includes a cylinder extending vertically, and the cylinder can drive the transmission seat 41 to move vertically. Using the cylinder to drive the transmission seat 41 to move vertically has the advantages of easy material acquisition and low cost.
[0050] like Figure 1 and Figure 2 As shown, the transmission assembly 40 also includes a transmission wheel 45 and a transmission chain 46. The transmission wheel 45 is rotatably arranged at the upper end of the cylinder. One end of the transmission chain 46 is connected to the bracket 10, and the other end of the transmission chain 46 bypasses the transmission wheel 45 and is connected to the transmission seat 41. When the push rod of the cylinder is extended, it can drive the transmission wheel 45 to rise. When the transmission wheel 45 rises, it drives the other end of the transmission chain 46 to rise, so that the transmission wheel 45 rotates and drives the transmission seat 41 to rise. When the push rod of the cylinder retracts, the transmission seat 41 drops.
[0051] In this embodiment, a switch is provided on the armrest, and the switch can control the output power of the cylinder and the working state of the cylinder.
