Problems solved by technology
[0005] However, in the prior art, because the crack growth rate of brittle materials is generally very fast, the traditional test method cannot effectively observe the direction and speed of crack growth. The test of mechanical properties is carried out separately and independently, which is not convenient enough

Embodiment Construction
[0017] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0018] refer to figure 2 , showing the structure of a measurement tool for testing material mechanical property parameters of the present invention Figure 1 . The measuring tool includes: a first fixed plate and a second fixed plate oppositely arranged; wherein, at least one rotation hole 23 and at least one screw hole 24 are respectively arranged on the first fixed plate, and the second fixed plate At least one rotation hole 23 and at least one screw hole 24 are arranged symmetrically on the upper side; among them, different rotation holes 23 on the first fixing plate and different rotation holes 23 on the second fixing plate can form different rotations correspondingly. Angle: The outer shape of the first fixed plate and the...

The embodiment of the invention provides a measuring tool for mechanical property parameters of test materials. The measuring tool comprises a first fixed plate, a second fixed plate, a first tensile head and a second tensile head, wherein the first fixed plate and the second fixed plate are symmetrically distributed and oppositely arranged, at least one rotating hole and at least one screw hole are respectively formed in the first fixed plate, at least one rotating hole and at least one screw hole are symmetrically formed in the second fixed plate; different rotating angles can be correspondingly formed between the different rotating holes in the first fixed plate and the different rotating holes in the second fixed plate; the first tensile head is mounted in and fixedly connected with one of the rotating holes in the first fixed plate; the second tensile head is mounted in and fixedly connected with one of the rotating holes in the second fixed plate adaptive to a rotating angle of the first fixed plate; the test materials are respectively fixed between the first fixed plate and the second fixed plate through the at least one screw hole so as to measure the mechanical property parameters of the test materials under the different rotating angles.
Description
technical field [0001] The invention relates to material mechanical property testing equipment, in particular to a measuring tool for testing material mechanical property parameters. Background technique [0002] Double-sided tape is usually used to bond various parts in smart terminals. For example, the touch screen is bonded to the casing with foam double-sided tape, the battery is bonded to the casing with easy-pull adhesive, and the camera lens is bonded to Bonded to the case, etc. In order to avoid the situation where the parts are separated from the shell, it is necessary to test the tensile strength of the double-sided tape. [0003] Existing test methods such as figure 1 As shown, the two test components 13 are bonded by double-sided adhesive tape 12, and one end of the two test components 13 is respectively sleeved on the two circular iron columns 11. When the two circular iron columns 11 move in opposite directions , a pulling force F will be generated to stretc...
