Description

Technical Field

[0001] The utility model relates to the field of pulling instruments, in particular to a device for detecting the bonding strength of rivets and heat insulation materials. Background Art

[0002] During construction, rivets need to be riveted onto thermal insulation materials so that the thermal insulation materials can be more stably fixed on the end faces. When the rivets are riveted onto the thermal insulation materials, the strength of the rivets riveted onto the thermal insulation materials needs to be tested, which requires a puller to perform the test. The existing puller only performs the pulling test by a single drive of a hydraulic cylinder, which results in uneven force on the test end, thereby affecting the accuracy of the test data and reducing the test efficiency of the puller.

[0003] A Chinese utility model patent with publication number CN216622114U discloses a device for detecting the bonding strength of rivets and thermal insulation materials. The patent uses multiple drive components to promote pulling by a puller to achieve a hand-like uniform effect. However, since the device needs to be tested directly on the thermal insulation material that has been installed and fixed on the wall, when the test fails, it may cause damage to the thermal insulation material, and it needs to be removed from the wall and replaced. This greatly reduces the detection efficiency. Therefore, there is an urgent need for a rivet and thermal insulation material bonding strength detection device that can be used for testing fixed thermal insulation material templates.

[0004] Therefore, the utility model provides a rivet and thermal insulation material bonding strength detection device to solve the above problems. Utility Model Content
