Description

Technical Field

[0001] The utility model belongs to the technical field of toughness testing, and in particular relates to a multi-training position sitting forward bending testing device. Background Art

[0002] For many years, the flexibility measurement has been mainly based on the standing forward flexion and traditional sitting forward flexion measurement methods. The existing standing forward flexion and traditional sitting forward flexion both use the point when the legs are straight, the feet are against the support board, the arms are stretched forward, and the fingers and soles of the feet are aligned as the base point (0cm). With this distance measurement method, the influence of the length of the upper and lower limbs and trunk on the performance has become increasingly prominent. At present, a new sitting forward flexion measurement method is adopted internationally, namely the new sitting forward flexion. The subjects all start at the same base point (0cm), and the distance of the arms extended forward is the measurement value. This measurement method minimizes the influence of body size on the forward flexion measurement, and more reasonably reflects the actual flexibility measurement value.

[0003] For example, an automatic alarm sitting forward flexion device disclosed in the utility model with authorization announcement number CN211561735U includes a base plate and a test bench arranged on one side of the base plate, a back plate perpendicular to the base plate is arranged on the other side of the base plate, the test bench can move along the length direction of the base plate, the test bench includes a support plate perpendicular to the base plate for the test subject's feet to rest on, and a measuring guide rail parallel to the base plate and mounted on the support plate, a hand push device that can move along the length direction of the measuring guide rail is arranged on the measuring guide rail, and the test bench is provided with an alarm device, which is used to alarm when the test subject is tested. When the test bench moves, the alarm device sounds an alarm. This solution solves the problem that during the test, the subjects often have irregular movements, such as unconsciously bending the knees, shaking the lower limbs in a large range, swinging the toes back and forth, etc., and the irregular movements will lead to inaccurate measurement results. The above technical solution cannot adjust the test position according to the different heights of testers, and there is instability in use. At the same time, it cannot fix the knees according to the different heights of testers, which affects the test results. For this reason, we propose a multi-training position sitting forward flexion test device. Utility Model Content

[0025] The test adjustment component 15 includes a cushion 154, which is arranged on the base plate 11. A first nut 155 is arranged on the cushion 154, and the first nut 155 is connected to the first ball screw 152. The first ball screw 152 is arranged in a first groove 156, and one end of the first ball screw 152 is connected to the driving shaft of the first permanent magnet bidirectional DC motor 151 located on one side of the base plate 11.

[0026] A control switch 153 is also provided on the seat cushion 154 . The control switch 153 is electrically connected to the first permanent magnet bidirectional DC motor 151 and can control the first permanent magnet bidirectional DC motor 151 .

[0027] First, the tester sits on the cushion 154, and then operates the first permanent magnet bidirectional DC motor 151 through the control switch 153. The first permanent magnet bidirectional DC motor 151 drives the first ball screw to rotate, and the first ball screw drives the first nut 155 to move. The first nut 155 drives the cushion 154 to move. When the sole of the patient's foot is in contact with the carrier 12, the first permanent magnet bidirectional DC motor 151 is stopped, thereby being able to meet the use of testers of different heights.

[0028] As a specific embodiment of this application, please refer to Figure 4 The binding assembly 16 includes a mounting seat 165, which is arranged on one side of the base plate 11. A fixing strap 161 is arranged on the mounting seat 165 to fix the knee joint of the tester, thereby avoiding inaccurate testing caused by bending of the knee joint during the test.

[0029] A guide slider 164 is provided on the mounting seat 165 , and the guide slider 164 is slidably provided in a guide slot 163 . The guide slot 163 is provided on one side of the base plate 11 , so as to adjust the position of the fixing strap 161 to fix the knee joints of testers of different heights.

[0030] Then push the mounting seat 165, the mounting seat 165 drives the guide slider 164 to move in the guide slot 163, and at the same time the mounting seat 165 drives the fixing strap 161 to move. When the fixing strap 161 moves to the knee position of the tester, the knee joint of the tester is fixed by the fixing strap 161.

[0031] Specifically, a locking bolt for the guide slider 164 is provided on the mounting seat 165 , so as to fix the position of the mounting seat 165 .

[0032] Furthermore, a flexible buffer pad 162 is provided on the fixing strap 161 to improve the comfort of the tester when using it.

[0033] As a specific embodiment of this application, please refer to Figure 5 as well as Figure 6 The measuring component 14 includes a push plate 141, which is arranged on the carrier 12. A second nut 142 is arranged at the bottom of the push plate 141. The second nut 142 is connected to a second ball screw 144. The second ball screw 144 is rotatably arranged in a second groove 143. The second groove 143 is arranged on the carrier 12. The second ball screw 144 is connected to a driving shaft of a second permanent magnet bidirectional DC motor 145 located on one side of the carrier 12, and can drive the push plate 141 to move in the thrust direction of the tester.

[0034] A pressing pad 147 is arranged on the push plate 141, and a pressure sensor 146 is arranged in the pressing pad 147. The model of the pressure sensor 146 is FXTH87EH11DT1. The pressure sensor 146 is connected to the controller 13. The controller 13 is arranged on the carrier 12, and the output end of the controller 13 is connected to the input end of the second permanent magnet bidirectional DC motor 145. The model of the controller 13 is a 51 single chip microcomputer, which can automatically control the second permanent magnet bidirectional DC motor 145 and detect the thrust of the tester in real time.

[0035] When the tester touches the pressing pad 147 with his hand, the pressure sensor 146 detects the pressure information, and the controller 13 controls the second permanent magnet bidirectional DC motor 145 to operate, and the second permanent magnet bidirectional DC motor 145 drives the second ball screw to rotate, and the second ball screw drives the second nut 142 to move, and the second nut 142 drives the push plate 141 to move. When the pressure of the push plate 141 disappears, it means that the tester's hand is separated from the push plate 141. At this time, the controller 13 controls the second permanent magnet bidirectional DC motor 145 to stop running. At this time, the position of the push plate 141 is fixed. Relying on the fast response speed of the pressure sensor 146, it can stop moving in the positive direction of the pressure when the pressure disappears, which can effectively overcome the cheating behavior of the tester pushing the push plate 141 with force.

[0036] As a specific embodiment of this application, please refer to Figure 1, multiple groups of test mechanisms 1 are arranged in an arc shape, and the center positions of the multiple groups of test mechanisms 1 point to the center positions of the electric telescopic rods 2.
