Description

Technical Field

[0001] The utility model relates to the technical field of testing device equipment, in particular to a safety shoe toe hardness testing device. Background Art

[0002] Labor protection shoes are a kind of shoes that provide safety protection for the feet. There are many types of them, such as toe protection, puncture resistance, insulation, acid and alkali resistance, etc. The hardness test of the toe of labor protection shoes is a standard for quality control of labor protection shoes. The hardness test can be performed by squeezing the toe. When the toe of traditional labor protection shoes is subjected to squeezing hardness test, the toe of the labor protection shoes moves during the squeezing process, making the toe test difficult and not conducive to the hardness test of the toe.

[0003] The application number is CN202121043787.1, and discloses a labor protection shoe toe hardness testing device, including a pedestal, the pedestal is connected with a slider, the slider is fixed with a support frame, and the support frame is slidably connected with a slide plate. The utility model pushes the slide plate down to make the rubber block squeeze the labor protection shoe and deform the rubber block. At this time, the screw rod is rotated to resist the support frame to clamp and fix the slide plate, so that the labor protection shoe is clamped between the pedestal and the slide plate to prevent the labor protection shoe from loosening. The fixed block is pushed to slide close to the test plate through the electric push rod, so that the test plate rotates counterclockwise to resist the toe of the labor protection shoe, and the toe is squeezed to check whether the toe is damaged and the damage condition, so as to facilitate the testing of the toe hardness. During the process of the test plate rotating and resisting the toe, the bottom plate moves into the bottom end of the toe, so that the roller rolls close to the support frame, so that the bottom plate supports the toe, so that the toe is quickly squeezed between the bottom plate and the test plate for hardness testing, thereby improving the testing efficiency.

[0004] The above document discloses a safety shoe toe hardness testing device with the following defects: when the device performs an extrusion test on the safety shoe, since the safety shoe has a certain hardness, the toe is prone to cause wear on the extrusion components, so the extrusion test components are prone to damage after long-term operation. When the components are damaged, the structure cannot disassemble the extrusion components and replace them with new ones, which reduces the service life of the device.

[0005] It can be seen from this that the existing labor protection shoe toe hardness testing device does not have the function of disassembling and replacing the components for the extrusion test. It is necessary to improve the existing deficiencies and provide a function that can disassemble and replace the components for the extrusion test of the device. Utility Model Content
