the first abutting part is positioned on the front side of the advancing direction of the test board, the front end of the sliding switching rod abuts against the first abutting part when the test board reaches the maximum position and pushes the sliding switching rod to slide, the sliding switching rod drives the driving sliding seat to be switched from a high-position state to a low-position state through a connecting rod, and the movable mounting seat moves towards the direction far away from the fixed mounting seat under the action of the spring force along with the descending of the driving sliding seat;

the second abutting part is positioned at the rear side of the test board, the rear end of the sliding switching rod abuts against the second abutting part when the test board returns to the initial position and pushes the sliding switching rod to slide, the sliding switching rod drives the driving sliding seat to be switched from a low-position state to a high-position state through a connecting rod, and the movable mounting seat moves towards the direction close to the fixed mounting seat along with the rising of the driving sliding seat; when the driving sliding seat is in a high position state, the connecting rod is perpendicular to the sliding switching rod.

Therefore, the movable mounting seat moves towards the direction close to the fixed mounting seat, and support is provided for the spring.

And thirdly, when the driving sliding seat is positioned at a high position, the connecting rod is perpendicular to the sliding switching rod.

Because the connecting rod with the perpendicular setting of slip switch lever, the slip switch lever is difficult for leading to because of the downward power of drive slide to slide, so realizes the position auto-lock function of drive slide in high position state.

Compared with the prior art, the invention has the characteristic of reducing the elasticity of the spring when the test board returns, so that the friction piece cannot contact with the lower surface of the sole when the test board returns, the test board is ensured to keep unchanged in height in multiple test processes, the test deviation caused by the descending and ascending of the height of the solution pool or the test board is reduced, and the accuracy of the sole slip-limiting test is improved.

A switching assembly 3 is arranged in the test board 11, the switching assembly 3 includes a sliding switching rod 31, a connecting rod 32 and a driving slide seat 33, a mounting through hole 111 penetrating along the moving direction of the test board 11 is formed on the test board 11, the sliding switching rod 31 is connected with the mounting through hole 111 in a sliding manner, and two ends of the sliding switching rod 31 extend out of the mounting through hole 111; a sliding groove 112 is formed on the test board 11 below each friction component 2, a driving sliding seat 33 is arranged in each sliding groove 112, and two ends of the connecting rod 32 are respectively connected with the sliding switching rod 31 and the driving sliding seat 33 in a rotating manner; a first wedge-shaped surface 232 is formed on the movable mounting seat 231, and a second wedge-shaped surface 331 matched with the first wedge-shaped surface 232 is formed on the upper end of the driving sliding seat 33; the drive carriage 33 has a high position state and a low position state; a first butting part 12 and a second butting part 13 are arranged in the solution pool 1.

The first abutting portion 12 is located at a front side of the test board 11 in the forward direction, the front end of the sliding switch rod 31 abuts against the first abutting portion 12 when the test board 11 reaches the maximum position and pushes the sliding switch rod 31 to slide, the sliding switch rod 31 drives the driving slide carriage 33 through the connecting rod 32 to switch from the high position state to the low position state, and the movable mounting seat 231 moves towards a direction away from the fixed mounting seat 221 under the elastic force of the spring 23 along with the descending of the driving slide carriage 33.

After the structure is adopted, according to the shoe sole slip-limiting tester for improving the testing accuracy, the switching component 3 is arranged, when the testing board 11 moves forwards to perform a slip-limiting test, and when the testing board 11 moves forwards to the maximum position, the front end of the sliding switching rod 31 abuts against the first abutting part 12, and drives the sliding switching rod 31 to slide in the direction opposite to the advancing direction of the testing board 11, so as to drive the driving sliding seat 33 to switch from the high position state to the low position state. Therefore, the support of the side of the movable mounting seat 231 departing from the spring 23 is removed, the elastic force of the spring 23 is reduced even to a non-elastic state, the friction member 24 is separated from the sole of the shoe 6 to be tested, and the test board 11 cannot return due to abutting interference between the friction member 24 and the sole during return stroke of the test board 11.
