Description

Technical Field

[0001] The utility model relates to the technical field of deformation testing, in particular to a device for testing the lateral deformation of an adhesive. Background Art

[0002] Adhesive is a substance with excellent bonding properties. It connects objects by bonding the surfaces through adhesion and cohesion.

[0003] A class of organic or inorganic, natural or synthetic substances that can connect the same or two or more homogeneous or heterogeneous parts (or materials) together and have sufficient strength after curing are collectively called adhesives or bonding agents, adhesives, and are usually referred to as glue.

[0004] At present, the adhesive lateral deformation testing device in the prior art usually uses an adhesive mold to perform lateral stretching for testing. When in use, since the two molds are cross-bonded, the clamping structure is not convenient for adjusting the position. When the mold is stretched, the force direction of the mold is offset, thereby affecting the test result. There is a problem that the position of the clamping structure cannot be easily adjusted. In addition, when in use, after the mold is bonded, the mold cannot be squeezed to ensure that the mold is tightly bonded, and the adhesive cannot be fully utilized. There is a problem that the mold cannot be squeezed and fixed after bonding. Utility Model Content
