DETAILED DESCRIPTION

[0019] Hereinafter, an embodiment of the protective shoe sole puncture testing device of the present invention will be described with reference to the accompanying drawings.

[0020] Figure 1-4The present invention shows a protective shoe sole puncture test device according to an embodiment of the present invention, comprising a base shell 1: an upper support frame 2 is fixedly connected to the top of the base shell 1, a press 3 is fixedly installed on the top of the inner cavity of the upper support frame 2, a pressure test cylinder 4 is also installed below the press 3, a connecting frame 5 is fixedly installed on the output end of the pressure test cylinder 4, a circular plate 1 6 is fixedly installed on the bottom of the connecting frame 5, both sides of the circular plate 1 6 are fixedly connected to sliders 20, both sides of the top of the base shell 1 are fixedly connected to fixed rails 21, and the sliders 20 are slidably connected to the inner cavity of the fixed rails 21. By cooperating with the slider 20 and the fixed rail 21, the circular plate 6 is driven to slide in the inner cavity of the fixed rail 21 during the downward movement of the circular plate 6, which effectively avoids the deviation of the circular plate 6 and improves the stability of the puncture test. Three rectangular holes 7 are opened on the top of the circular plate 6, and a circular hole 8 connected to the three rectangular holes 7 is opened at the central axis of the top of the circular plate 6. The inner cavity of the rectangular hole 7 is slidably connected with a slider 9, and a circular plate 2 10 is fixedly connected and installed below the slider 9. Three motors 15 are fixedly installed on the surface of the circular plate 6. The output shaft passes through the inner cavity of the rectangular hole 7 and is fixedly installed with a threaded rod 16, a slider 9 is threadedly connected to the surface of the threaded rod 16, a puncture nail 11 is fixedly installed below the circular plate 10, and the three puncture nails 11 are of different sizes. The inner cavity of the base shell 1 is provided with a movable moving block 12, and the top of the moving block 12 is fixedly connected with two symmetrical convex strips 13, and the top of the convex strip 13 passes through the top of the base shell 1. The top of the base shell 1 is provided with two movable grooves 14 for the convex strip 13 to slide, and the inner cavity of the base shell 1 is fixedly connected with a support plate 17, and the moving block 1 2 is slidably connected to the top of the support plate 17. Through the setting of the support plate 17, the moving block 12 is slidably connected to the top of the support plate 17, which can limit the moving block 12 and prevent the moving block 12 from rotating with the rotation of the threaded rod 19. In addition, the moving block 12 can be supported, thereby improving the bearing capacity of the moving block 12. The rear side of the base shell 1 is fixedly installed with a motor 18, and the output shaft of the motor 18 is fixedly installed with a threaded rod 19. The threaded rod 19 is rotatably connected to the inner cavity of the base shell 1, and the moving block 12 is threadedly connected to the surface of the threaded rod 19.

[0021] Working principle: When the utility model is used, the user places the sole to be tested on the top of the two convex strips 13, and then the motor 18 drives the threaded rod 19 to rotate. As the threaded moving block 12 and the convex strip 13 move forward and backward, the puncture position of the sole is facing the middle of the bottom of the circular plate 6. When a puncture nail 11 is needed, the corresponding motor 15 is started to drive the threaded rod 16 to rotate, and the slider 9 slides in the inner cavity of the rectangular hole 7 due to the thread, so that the circular plate 10 at the bottom of the slider 9 moves. To the bottom of the inner cavity of the circular hole 8, the pressure test cylinder 4 is then extended, driving the connecting frame 5 and the circular plate 6 to move downward, so that the puncture nail 11 at the central axis of the bottom of the circular plate 6 contacts the sole, and the value on the press machine 3 is read according to the penetration of the puncture nail 11. The three puncture nails 11 can be switched freely, and the puncture position of the sole on the convex strip 13 can be changed because the motor 2 18 drives the threaded rod 2 19 to rotate, and the thread drives the moving block 12 and the convex strip 13 to move back and forth, so that the puncture position of the sole can be changed.

[0022] To sum up: the protective shoe sole puncture test device places the sole on the top of the two convex strips 13, and then starts the corresponding motor 15 to drive the threaded rod 16 to rotate according to the demand, so that the slider 9 slides in the inner cavity of the rectangular hole 7, and drives the circular plate 2 10 to move to the bottom of the middle of the circular plate 6, and then the pressure test cylinder 4 is extended to make the puncture nail 11 under the circular plate 2 10 pierce the sole, and read the value on the press 3. The three puncture nails 11 can be switched as needed, and the sole placed on the convex strip 13 can be driven by the motor 2 18 to drive the threaded rod 2 19 to rotate, so that the moving block 12 and the convex strip 13 move back and forth, thereby changing the puncture position of the sole, so as to achieve the purpose of automatically switching puncture nails of different diameters, and the sole can automatically move back and forth, switch the puncture position, and improve the test efficiency.
