A nut 19 is nested on the screw 18 .

Embodiment one:

The use steps and principle of the present invention are:

1. Place the sand board 16 in the middle area surrounded by a plurality of third vertical supports 17 on the base 1, and use a screwdriver to screw the screw 18 on the third vertical support 17 to make it stand against the edge of the sand board 16, And further continue to lock the screw 18 so that the sand board 16 is embedded and fastened to prevent the sand board 16 from getting loose.

2. Put the foot model 11 in the shoe to be tested, and tie the shoelace. The heel place of foot model 11 is provided with pressure sensor. The foot mold 11 is fixed on the bottom of the movable joint 901, and the adjusting joint 902 is adjusted to make the first connecting rod 9 stretch or shorten until the reading of the pressure sensor on the foot mold 11 is within the standard reference range.

3. Start the motor 13, the first driven wheel rotates, and through the transmission of the transmission chain 12, the second driven wheel, and the rotating rod 7, the runner 8 is driven to rotate. One end of the second connecting rod 10 moves circularly under the drive of the runner 8 , and the other end of the second connecting rod 10 pulls the pallet 5 to reciprocate on the horizontal track 4 . At the same time of the reciprocating movement, since the direction of the second connecting rod 10 is obliquely downward, there is also a vertical downward component force, which is manifested as a vertical downward pressure on the shoe. Actually, people wearing shoes also have such force , and with the change of the center of gravity of the human body, the force is also changing all the time. During this process, the inclination of the second connecting rod 10 is always changing, so the magnitude of the component force is always changing.

4. Every time the motor 13 rotates once, the shoe completes a reciprocating motion on the sand board 16, keeping the motor 13 continuously rotating, it can complete tens of thousands of reciprocating motions in a relatively short period of time.

5. Stop the motor 13, take off the shoes, observe the wear of the soles and the deformation of the bonding parts between the soles and the uppers.

Embodiment two:

As shown in Figure 8, the sand board 16 is placed obliquely, and the sand board 16 is locked with screws 18 located at different positions on the third vertical support 17. Since the inclined sand board is easy to loosen, nest it on the screw 18 if necessary Nut 19, compresses sand plate 16 edges. Afterwards, according to the description of step 2 to step 5 in the first embodiment, the test operation is carried out again, and the degree of wear resistance of one side of the sole and the deformation resistance of the joint between the sole and the upper can be mainly analyzed.

Embodiment three:

Change the direction of rotation of the motor, as shown in Figure 1, when the runner 8 rotates counterclockwise, the wear at the heel is more serious, and when the runner 8 rotates clockwise, the wear at the sole of the shoe is more serious. In the complete test cycle, set the number of forward and reverse rotations to be different, or only set the motor to rotate clockwise or only to rotate counterclockwise, so as to verify the wear resistance of the heel and sole of the shoe in a targeted manner And the deformation resistance of the joint between the sole and the upper.
