Background

The anti-slip performance of the shoe sole directly influences the comfort and safety of the shoe when the shoe is worn, is poor in anti-slip performance, and is easy to slip and fall when the shoe is walking, so that the anti-slip performance test of the shoe is an important test in the comprehensive performance test of the shoe.

Chinese patent CN108760621B proposes that the above-mentioned patent has the problem that the contact between the anti-slip test board and the sole is not tight, so that the anti-slip test board cannot effectively contact with the sole during the anti-slip test of the sole, and the detection accuracy of the anti-slip performance of the shoe is reduced. In view of the above drawbacks, chinese patent CN108760621B proposes to improve the contact between the sole and the friction element by providing a blocker. However, because the sole need carry out a lot of measurements to same sole during the test, 108760621B need just can get back the second piston rod that drives actuating cylinder to the second of withdrawing after once measuring the end with first piston rod decline, thereby drive and survey test panel and get back to initial position, otherwise the friction member of perk will cause the top with the anti-skidding decorative pattern of sole bottom surface, make and survey test panel unable return, and because the special construction of friction member, in case support with anti-skidding decorative pattern, along with the removal of survey test panel, it can be more firm to support the top with the sole with the friction member.

Although the chinese patent CN108760621B solves the problem of improving the contact degree of the sole, the position of the first piston rod after descending and ascending may not be consistent, so that there may be a large error in each measurement result.

In view of the above, the applicant has made an intensive study on the above-mentioned defects in the prior art, and has made this invention.

Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following specific examples.

As shown in fig. 1 to 3, the improved anti-slip testing device for shoe soles according to the present invention comprises a solution tank 2, a testing board 21, a thrust sensor 25, a second driving cylinder 24 and a shoe tree 11 for fixing a shoe 12 to be tested; the testing board 21 is arranged in the solution pool 2, a second driving cylinder 24 is fixedly mounted on the side wall of the solution pool 2, and a piston rod of the second driving cylinder 24 is connected with the testing board 21 through the thrust sensor 25. The upper surface of the test board 21 is provided with a plurality of friction components 3, and each friction component 3 comprises a fixed seat 31, a rack 32, a spring 33 and a friction piece 34; the fixed seat 31 is fixedly installed on the upper surface of the test board 21, the rack 32 is slidably disposed in the fixed seat 31, the spring 33 abuts between the rack 32 and the fixed seat 31, the friction member 34 is rotatably connected to the fixed seat 31, and the friction member 34 has a tooth portion 341 engaged with the rack 32; the upper end surface of the friction member 34 has a plurality of grooves 342.

Preferably, the bottom of the solution pool below the test board is provided with a slide rail 27, the lower surface of the test board is provided with a slide seat 28, and the test board 21 is slidably connected on the slide rail 27 through the slide seat 28.

A first abutting portion 22 and a second abutting portion 23 are fixedly arranged in the solution pool 2, and a first contact switch 211 and a second contact switch 212 are respectively arranged on the front side and the rear side of the test board 21 in the moving direction; one side of the rack 32, which is far away from the spring 33, is provided with a locking telescopic cylinder 5; when the test board 21 moves forward to the maximum position under the driving of the second driving cylinder 24, the first contact switch 211 contacts the first abutting portion 22, and the telescopic rod of the locking telescopic cylinder 5 extends to abut against the rack 32 to separate the upper end surface of the rack 32 from the shoe 12 to be tested; when the test board 21 moves backward to the initial position under the driving of the second driving cylinder 24, the second contact switch 212 contacts the second abutting portion 23, and the telescopic rod of the locking telescopic cylinder 5 retracts to the initial position.

After adopting the structure, the improved shoe sole slip resistance testing device provided by the invention at least has the following beneficial effects:

through the arrangement of the locking telescopic cylinder 5, when the test board 21 returns, the telescopic rod of the locking telescopic cylinder 5 abuts against the rack 32, so that the spring 33 cannot push the rack 32, and the friction piece 34 cannot tilt. Thus, when the test board 21 moves backward, the friction member 34 will not interfere with the sole of the shoe 12 to be tested to affect the return of the test board 21. When the test board 21 returns to the initial position, the locking telescopic cylinder 5 retracts to return to a state where the spring 33 abuts against the rack 32 and further abuts against the upper end surface of the friction member 34 against the lower surface of the shoe 12 to be tested.

Preferably, the sole anti-slip testing device further comprises a frame 1 and a first driving cylinder 26; the first driving cylinder 26 is arranged on the frame 1, and the solution pool 2 is arranged at the upper end of the first driving cylinder 26. The shoe tree 11 is fixedly installed on the frame 1 through a bracket. Through setting up first actuating cylinder 26 can drive solution pool 2 rises and descends, makes things convenient for the installation of the part of testing board 21 on board 21. The distance between the test board 21 and the shoe 12 to be tested can be conveniently adjusted.

Preferably, the locking telescopic cylinder 5 is an air cylinder, and the fixed seat 31 is provided with an air inlet 311 connected with the air cylinder. Furthermore, all the air inlets 311 on the fixed seat 31 are connected with the same air source through an electric control valve; the electric control valve is connected with a controller (not shown in the figure), and the controller is respectively and electrically connected with the first contact switch 211 and the second contact switch 212. Thus, when the cylinder is charged, the extension of the piston rod of the locking telescopic cylinder 5 pushes the rack 32 against, limiting the extension of the spring 33. When the gas is discharged, the piston rod of the locking telescopic cylinder 5 returns to the original position, and the normal action of the rack 32 driven by the spring 33 is not influenced.

Preferably, the locking telescopic cylinder 5 is an electric telescopic cylinder, each electric telescopic cylinder is electrically connected with a controller, and the controllers are respectively electrically connected with the first contact switch 211 and the second contact switch 212. Therefore, the structure can be simpler in an electric control mode.

The controller and the power supply are both disposed on the test board 21. The controller is a single chip microcomputer or a PLC controller. The power source is a storage battery (not shown in the figure), so that the test board 21 is prevented from interfering with the test data with the outside through wires.

Preferably, the upper end surface of the friction member 34 is maintained in a horizontal state while the test plate 21 is moved backward. During the return stroke, the upper end surface of the friction member 34 is kept in a horizontal state, and is spaced from the lower surface of the sole as far as possible, so that the test board 21 can move backwards conveniently.

Compared with the prior art, the invention can ensure that the height of the test board 21 does not need to be reduced when the test board 21 returns, so that the conditions of the anti-slip test of the sole of the same shoe are kept as the same as possible, and the effect of the anti-slip test is ensured.
