Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of labor protection shoe testing equipment, in particular to a steel toe impact testing machine. Background Art
[0002] In fields like industrial production and construction, safety shoes are essential equipment for worker safety. The steel toe cap of these shoes must possess excellent impact resistance to protect workers' feet from being hit by heavy objects. Therefore, accurate testing of the impact resistance of these shoes is crucial.
[0003] In the existing technology, most steel toe impact testing machines do not have a clamping device when in use. The position of the safety shoe on the test bench cannot be fixed. The position of the safety shoe may change with each impact, which will lead to inconsistent impact positions of the steel toe, poor repeatability of the test results, and inability to accurately evaluate the impact resistance of the steel toe of the safety shoe. Therefore, we propose a steel toe impact testing machine to solve this problem. Utility Model Content

[0013] In the present invention, a steel head impact testing machine is provided, in which the vertical movement of the handle drives the second moving block to move under the restriction of the guide rod.

A motor is set to drive the bevel gear one to rotate, and then the bevel gear two and the bevel gear three are driven to rotate, and then the screw is driven to rotate in the bracket, thereby driving the moving block one to move relative to the slide groove, thereby driving the fixed block and the clamp to move relative to each other, thereby realizing the clamping of the labor protection shoes. The transmission design of the bevel gear one, the bevel gear two and the bevel gear three can realize power transmission in different directions, and at the same time can also improve the transmission accuracy. This high-precision transmission can ensure that the moving distance and speed of the clamp are accurately controlled, thereby better adapting to the clamping needs of labor protection shoes of different sizes.
