However, one or more embodiments can also be implemented by those skilled in the art without these specific details.

[0024] As Figures 1-4As shown in the figure, a performance testing device for protective elderly shoes includes a workbench 1. There is a box body 6 on the top of the workbench 1. The front end of the box body 6 is open. A sliding table 7 is slidably connected inside the box body 6 at the position on the top of the workbench 1. In the center of the top of the sliding table 7, there is an installation table 8. In the center of the top of the installation table 8, there is a pressure sensor 9. At the four corner positions of the top of the installation table 8, there are elastic telescopic components 2 respectively. The top of multiple elastic telescopic components 2 is provided with a top plate 10. On the left side of the box body 6, there is a first power component 3. The output end of the first power component 3 is fixedly connected to the sliding table 7. On the top of the box body 6, there is a second power component 4. On the front side of the first power component 3 on the left inner side of the box body 6, there is a tensiometer 11. The output end of the second power component 4 is provided with a sliding component 5.

[0025] In the above technical solution, by setting the pressure sensor 9, the downward pressure of the shoe on the top plate 10 can be detected. By setting the first power component 3, the sliding table 7 can be driven to slide rightward on the workbench 1, providing conditions for the test. By setting the second power component 4, the sliding distance of the sliding component 5 can be controlled, so that the bottom of the shoe can be pressed against the top surface of the top plate 10. By setting the tensiometer 11, the tensile force data can be directly observed, facilitating the intuitive test of the anti-slip performance of the shoe. By setting the sliding, it is convenient to fix shoes of different shoe sizes.

[0026] In the present utility model, the elastic telescopic component 2 includes a fixed column 201. The fixed column 201 is fixedly connected to the sliding table 7. An expansion cavity 202 is opened inside the fixed column 201. There is an expansion hole 203 at the top of the fixed column 201. The expansion hole 203 and the expansion cavity 202 are coaxially arranged and the diameter of the expansion hole 203 is smaller than the diameter of the expansion cavity. An abutting plate 204 is movably arranged in the expansion cavity 202. Between the bottom of the abutting plate 204 and the bottom of the expansion cavity 202, there is an expansion spring 205. At the top of the abutting plate 204, there is a connecting column 206. The top of the connecting column 206 is fixedly connected to the bottom of the bottom plate.

[0027] In the above technical solution, by arranging the elastic telescopic component 2 between the top plate 10 and the sliding table 7, during the downward sliding of the sliding component 5, when the bottom of the shoe abuts against the top plate 10, if the sliding component 5 continues to move downward, the spring will be compressed to give an upward force to the top plate 10, protecting the pressure sensor 9 and avoiding damage to the pressure sensor 9 caused by the excessive downward sliding distance of the sliding component 5.

[0028] In the present utility model, the first power assembly 3 includes an installation channel 301 which is opened at the middle position of the left side wall of the box body 6 corresponding to the middle of the sliding table 7.

A cylinder 303 is fixedly connected to the top of the installation plate 302. The cylinder 303 straddles inside the installation channel 301. At the front side position of the cylinder 303 on the left outer side wall of the box body 6, there is a regulating valve 304. The air inlet end of the cylinder 303 is communicated with the regulating valve 304 through an air pipe. The output end of the cylinder 303 is fixedly connected with a vertical plate 305. The right side of the vertical plate 305 is welded to the left side of the sliding table 7. One end of the tensiometer 11 is fixedly connected to the left side surface of the vertical plate 305.

[0029] In the above technical solution, by straddling and fixing the cylinder 303 on the installation plate 302 inside the installation channel 301 and communicating the air inlet end of the cylinder 303 with the regulating valve 304 through an air pipe, the air intake amount of the cylinder 303 can be controlled, so that the sliding speed of the sliding table 7 can be controlled, and thus the friction performance of the shoes under different motion states can be simulated.

[0030] In the present utility model, the second power assembly 4 includes a motor 401 which is fixedly connected to the left side position at the top of the box body 6. The output shaft of the motor 401 passes through the box body 6 and is rotatably connected thereto. A first threaded rod 402 is fixedly connected to the output shaft of the motor 401.

[0031] In the above technical solution, by setting the motor 401, the sliding distance of the sliding assembly 5 inside the box body 6 can be driven, making it more convenient when the shoes are put on the shoe mold 506.

[0032] In the present utility model, the sliding assembly 5 includes a T-shaped chute 501 which is opened at the top of the installation channel 301 on the left inner wall of the box body 6. A group of T-shaped sliding plates 502 are slidably connected inside the T-shaped chute 501. Among the group of T-shaped sliding plates 502, a first threaded hole 503 is opened at the top of the upper T-shaped sliding plate. The first threaded hole 503 is threadedly connected with the first threaded rod 402. On the side of the group of T-shaped sliding plates 502 away from the left inner wall of the box body 6, there is a connecting plate 504 connected. At the center of the right side surface of the connecting plate 504, there is a right-angled connecting rod 505. At the bottom of the connecting rod 505, there is a shoe mold 506. On the right side of the shoe mold 506, there is a first abutting surface 507. An installation groove 508 is provided on the first abutting surface 507. A micro motor 509 is installed inside the installation groove 508. A second threaded rod 510 is provided at the output end of the micro motor 509. A cooperating strip 511 is slidably arranged inside the installation groove 508. On the end surface of the cooperating strip 511 close to the micro motor 509, there is a second threaded groove 512. The second threaded groove 512 is threadedly connected with the second threaded rod 510. On the end surface of the cooperating strip 511 away from the micro motor 509, there is an abutting block 513.

[0033] In the above technical solution, the T-shaped sliding groove 501 and the T-shaped sliding plate 502 play a guiding role in the sliding of the sliding assembly 5. By arranging a first abutting surface 507 on the right side of the shoe mold 506 and installing a micro motor 509 in the installation groove 508 opened on the first abutting surface 507, the rotation of the micro motor 509 can drive the rotation of the second threaded rod 510, and further drive the cooperation bar 511 to move rightward in the installation groove 508, so that the length between the shoe mold 506 and the abutting block 513 can be changed, which can be used to fix shoes of different sizes.

[0034] The working principle of a performance testing device for a protective elderly shoe of the present utility model is as follows:

[0035] During use, first put the shoe on the shoe mold 506, start the micro motor 509, so that the rotation of the micro motor 509 drives the second threaded rod 510, thereby driving the cooperation bar 511 to slide rightward in the installation groove 508, driving the rightmost end of the abutting block 513 to abut against the rightmost end inside the shoe body, and fixing the shoe on the shoe mold 506. Then start the motor 401, the rotation of the motor 401 drives the rotation of the first threaded rod 402, which can drive the sliding assembly 5 to slide downward in the T-shaped sliding groove 501, and further drive the shoe mold 506 together with the shoe to move downward. When the bottom of the shoe abuts against the top plate 10 during the downward movement of the shoe, until the pressure received by the pressure sensor 9 reaches the conditions required for testing, the motor 401 stops rotating. Thereafter, the air cylinder 303 intakes air, and the output shaft of the air cylinder 303 extends rightward, which can drive the slide table 7 to slide rightward on the workbench 1. At the same time, when the slide table 7 moves rightward, the slide table 7 will drive the pulling end of the tensile force to move rightward. At this time, the friction force can be calculated by reading the tensiometer 11.

[0036] In this article, specific examples are used to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
