Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] Referring to Figures 1 - 4 As shown, the present utility model provides a puncture resistance test device for the sole protection plate of labor protection shoes, including a workbench 1, an L-shaped seat 2 fixedly connected to the top of the workbench 1, a testing mechanism 3 arranged on the L-shaped seat 2, and a clamping mechanism 4 fixedly connected to the top of the workbench 1.

[0026] The testing mechanism 3 includes a cylinder 302 fixedly connected to the L-shaped seat 2, a circular ring 311 is arranged inside the U-shaped plate 306, a puncture needle 309 is arranged outside the circular ring 311, a servo motor 307 is arranged on the right side of the U-shaped plate 306, and a scale bar 305 is arranged on the front side of the U-shaped plate 306.

[0027] In a further embodiment, referring to Figures 1 - 4, a bracket 308 is fixedly connected to the outside of the servo motor 307. The bracket 308 is used to fix the servo motor 307 and fix it on the right side of the U-shaped plate 306. The bracket 308 is fixedly connected to the right side of the U-shaped plate 306. The servo motor 307 is fixedly connected to a transmission rod 310 through an output shaft. The servo motor 307 can drive the transmission rod 310 to rotate through the output shaft. The left end of the transmission rod 310 penetrates through the U-shaped plate 306 and is movably connected to the U-shaped plate 306 through a bearing. Under the action of the bearing, the transmission rod 310 can rotate within the U-shaped plate 306. A ring 311 is fixedly connected to the outside of the transmission rod 310. The rotation of the transmission rod 310 can drive the ring 311 to rotate, thereby adjusting the model of the puncture needle 309 outside the ring 311. An internal thread cylinder is fixedly connected to the outside of the ring 311. An external thread block is threadedly connected to the inside of the internal thread cylinder. The puncture needle 309 is fixedly connected to the outside of the external thread block. The internal thread cylinder and the external thread block can install and disassemble the puncture needle 309. The puncture needles 309 are distributed at equal intervals from thick to thin on the outside of the ring 311.

[0028] In this embodiment, the servo motor 307 can drive the ring 311 to rotate through the transmission rod 310, thereby adjusting the model of the puncture needle 309 on the outside. After adjusting to an appropriate model, it is pushed downward by the cylinder 302 for puncture testing.

[0029] In a further embodiment, referring to Figure 1 and Figure 3 , a fixing strip 304 is fixedly connected to the left side of the U-shaped plate 306. The fixing strip 304 is used to fix the scale strip 305. The scale strip 305 is fixedly connected to the bottom of the fixing strip 304. The bottom scale mark of the scale strip 305 at the starting position is in the same plane as the bottom end of the puncture needle 309. The scale strip 305 moves downward following the puncture needle 309. A through hole 301 is opened at the top of the workbench 1. The through hole 301 facilitates the passing of the scale strip 305. The telescopic end of the cylinder 302 is fixedly connected to a pressure sensor 303. The pressure sensor 303 is fixedly connected to the bottom of the U-shaped plate 306. The pressure sensor 303 can sense and test the pressure of the cylinder 302 on the U-shaped plate 306.

[0030] In this embodiment, data such as the pressure magnitude and puncture depth can be obtained during the puncture test, which is convenient for subsequent judgment of the performance of the protective plate on the sole of the labor protection shoes.

[0031] In a further embodiment, referring to Figures 1 - 2, the clamping mechanism 4 includes an L-shaped plate 401 fixedly connected to the top of the workbench 1. The L-shaped plate 401 is used for installing the electric telescopic rod 403, and there are two groups of L-shaped plates 401. The two groups of L-shaped plates 401 are symmetrically distributed on the top of the workbench 1. An electric telescopic rod 403 is fixedly connected to the L-shaped plate 401. The telescopic end of the electric telescopic rod 403 is fixedly connected to a frame 402. The frame 402 can fix the sole protection plate of the labor protection shoes without affecting the puncture operation.

[0032] In this embodiment, before the test, the electric telescopic rod 403 pushes the frame 402 to move downward to fix the sole protection plate of the labor protection shoes and prevent displacement during the test.

[0033] The working principle of the present utility model is as follows:

[0034] Before the test, place the sole protection plate of the labor protection shoes to be tested on the workbench 1, start the electric telescopic rod 403 to make it extend. The extension of the electric telescopic rod 403 pushes the frame 402 to move downward to fix the sole protection plate of the labor protection shoes;

[0035] Determine the test pressure and the model of the puncture needle 309 according to the test requirements. The model of the puncture needle 309 can be replaced by starting the servo motor 307;

[0036] Start the cylinder 302. The cylinder 302 extends to push the pressure sensor 303 and the puncture structure below to perform a puncture operation on the sole protection plate of the labor protection shoes. Stop when the pressure value displayed by the pressure sensor 303 reaches the set value. At this time, observe the puncture depth, which provides a basis for judging the puncture resistance performance of the sole protection plate of the labor protection shoes according to the puncture force and the puncture depth.

[0037] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
