Technical Field
The invention relates to the field of sole performance testing, in particular to a sole slip-limiting tester for improving testing accuracy.
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 cn201710889040.x discloses a multipurpose shoe detection machine with slip-stopping detection function, which comprises a frame, a shoe positioning device, a shoe comprehensive wear-resisting property detection device and a shoe slip-stopping property detection device; the shoes comprehensive wear resistance detection device includes: the shoe comprises a front sole bending and abrasion resistance detection device, a heel abrasion resistance detection device and a vamp abrasion resistance detection device, wherein the shoe slip resistance detection device comprises a slip resistance test board which is in direct contact with a sole.
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 need carry out a lot of measurements to same sole when the sole is tested in order to reduce single measurement error, 108760621B need can just 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 the top with anti-skidding decorative pattern, along with the removal of surveying 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.
Disclosure of Invention
The invention mainly aims to provide a sole skid-proof tester for improving the testing accuracy, which has the advantages that the friction piece and the sole are prevented from abutting and interfering when a testing board returns, and the testing error caused by the rising of the testing board after the testing board descends is avoided.
In order to achieve the above purpose, the solution of the invention is:
a sole limited slip tester for improving the testing accuracy comprises a solution tank, a testing board and a plurality of friction components, wherein the friction components are arranged on the testing board and used for improving the adhesive force of a sole surface during testing; the fixed seat is fixedly arranged on the upper surface of the test board, the rack is arranged in the fixed seat in a sliding manner, the lower end of the rack is connected with a fixed mounting seat, a movable mounting seat is movably arranged in the fixed seat, two ends of the spring respectively abut against the fixed mounting seat and the movable mounting seat, the friction piece is rotatably connected to the fixed seat, and the friction piece is provided with a tooth part meshed with the rack; the upper end surface of the friction piece is provided with a plurality of grooves;
a switching assembly is arranged in the test board, the switching assembly comprises a sliding switching rod, a connecting rod and a driving sliding seat, an installation through hole penetrating along the moving direction of the test board is formed in the test board, the sliding switching rod is connected with the installation through hole in a sliding mode, and two ends of the sliding switching rod extend out of the installation through hole; a sliding groove is formed on the test plate below each friction assembly, a driving sliding seat is arranged in each sliding groove, and two ends of the connecting rod are respectively connected with the sliding switching rod and the driving sliding seat in a rotating mode; a first wedge-shaped surface is formed on the movable mounting seat, and a second wedge-shaped surface matched with the first wedge-shaped surface is formed at the upper end of the driving sliding seat; the driving sliding seat has a high state and a low state; a first butting part and a second butting part are arranged in the solution pool;
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.
Furthermore, the sole slip-limiting tester also comprises a frame, a lifting device, a thrust sensor, a driving cylinder and a shoe tree for fixing the shoe to be tested; the lifting device is arranged on the rack, and the solution pool is arranged at the upper end of the lifting device; and a driving cylinder is fixedly mounted on the side wall of the solution pool, and a piston rod of the driving cylinder is connected with the test plate through the thrust sensor.
Furthermore, the first abutting portion is an inner side wall of the solution pool on the front side of the advancing direction of the test plate.
Further, when the driving slide seat is in a high position state, the rear end of the sliding switching rod is flush with the rear end face of the test board; when the driving sliding seat is located at a low position, the front end of the sliding switching rod is flush with the front end face of the test board.
Further, when the driving sliding seat is located at a low position, the upper end face of the friction piece is in a horizontal state.
After the structure is adopted, the invention relates to a sole slip-limiting tester for improving the testing accuracy, which at least has the following beneficial effects:
when the test board moves forwards to perform anti-slip test, and the test board moves to the maximum position, the front end of the sliding switching rod abuts against the first abutting portion, and drives the sliding switching rod to slide in the direction opposite to the advancing direction of the test board, so as to drive the driving sliding seat to switch from the high state to the low state. The support of one side of the movable mounting seat, which is far away from the spring, is removed, the elasticity of the spring is reduced even to a non-elastic state, the friction piece is separated from the sole of the shoe to be tested, and the test board cannot return due to abutting interference between the friction piece and the sole during return stroke.
When the test board returns to the initial position, the rear end of the sliding switching rod abuts against the second abutting part and drives the sliding switching rod to slide in the reverse direction of the return direction of the test board, so that the sliding switching rod drives the sliding switching rod to ascend through the connecting rod and is switched from the low state to the high state. 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. In this way, the force imparted to the movable mount by the spring is converted by the first and second wedge surfaces into a force that drives the slide downward. 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.
