Adjustable uniformly distributed force loading device for cantilever stretching

The utility model relates to the field of tensile tests, in particular to an adjustable uniformly distributed force loading device for cantilever stretching. Comprising at least one double-end clamp used for clamping a plate; the sliding rail is connected with the double-end clamp; the loading device is connected with the double-end clamp; and the expansion bracket is connected with the loading device and drives the loading device and the double-end clamp to slide on the sliding rail, so that the loading width adjustment is realized. The device is formed by combining a plurality of components, is convenient to mount and dismount, is simple to operate, is suitable for plate test pieces with various thicknesses and widths, and has relatively high practical value and popularization value. 本实用新型涉及拉伸试验领域，具体涉及一种可调节的悬臂拉伸用均布力加载装置。包括：双头夹，至少一个所述双头夹用来夹持板件；滑轨，所述双头夹与所述滑轨相连；加载装置，所述加载装置与所述双头夹相连；伸缩架，所述伸缩架与所述加载装置相连，带动加载装置和双头夹在滑轨上滑动，实现加载的宽度调节。本装置由多个部件组合而成，安装方便，拆卸便捷，操作简单，适用于多种厚度和宽度的板材试件，具有较高的实用价值和推广价值。
