Problems solved by technology
[0002] Most of the currently used electrical switches are used to control the on-off of the electrical power supply. During processing, it is generally necessary to perform a bending test on its individual components. Common bending tests include four-point bending tests and three-point bending tests. However, the existing Generally, the bending test device can only perform one of the tests alone, and cannot perform the conversion of the two tests. For this reason, the tester often needs to transfer the components to the corresponding equipment for testing, which is very troublesome. For this reason, a flexible use is needed.

The invention discloses a bending test device for switch elements of electric appliances. The bending test device comprises a protective cover. The protective cover is fixed to the top of a base, a fixed plate is fixed to the inner side of the protective cover, a first mounting plate is arranged above the fixed plate and is slidably nested in the inner side of the protective cover, a driving structure is arranged on the top of the first mounting plate, an adjusting structure is connected with the bottom of the first mounting plate and comprises a first threaded rod, the first threaded rod is fixed to the bottom of the first mounting plate, and a first connecting plate sleeves the first threaded rod. The bending test device has the advantages that structures such as the first connecting plate, guide rods, two placing blocks, two second ejector blocks, a first ejector block, an electric cylinder and the first mounting plate are used with one another, adjusting nuts only need to rotate, accordingly, four-point bending tests and three-point bending tests can be switched over, and the bending test device can be selectively used according to requirements of users; the integral bending test device is simple in structure and low in manufacturing cost and can be flexibly used.
Description
technical field [0001] The invention relates to the technical field of bending testing devices, in particular to a bending testing device for electrical switch elements. Background technique [0002] Most of the currently used electrical switches are used to control the on-off of the electrical power supply. During processing, it is generally necessary to perform a bending test on its individual components. Common bending tests include four-point bending tests and three-point bending tests. However, the existing Generally, the bending test device can only perform one of the tests alone, and cannot perform the conversion of the two tests. For this reason, the tester often needs to transfer the components to the corresponding equipment for testing, which is very troublesome. For this reason, a flexible use is needed. Bend test device. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a bending ...
