[0001] The utility model relates to the technical field of nondestructive testing, in particular to a nondestructive testing device. Background Art

[0002] With the increasing number of household appliances in people's homes, plugs and sockets are more widely used. Sockets can solve the problem of insufficient pre-installed wall sockets and extend the power transmission distance. Plugs are essential components for every electrical device. In the production process of plugs and sockets, it is necessary to test the final products to prevent defective products from entering the market.

[0003] In the existing non-destructive testing devices for plugs and sockets, the detection efficiency of plugs is low, and the installed plugs need to be removed one by one, which increases the amount of operation and cannot be continuously tested in large quantities; and when testing the sockets, different detection plugs must be pulled out and selected according to the type of the socket, which also has an adverse effect on the detection efficiency. For this reason, we propose a non-destructive testing device. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a non-destructive testing device with a convenient testing unit, which can improve the testing efficiency of plugs and sockets: the push plate can pull out the plugs for insertion testing from the fixed plug plate at the same time under the action of the electric push rod, eliminating the trouble of the test personnel to remove the plugs one by one; the multi-purpose plug has two types of plugs, two-head and three-head, and different types of jacks on the socket can be tested through a set of plugs; it also has multiple practical components, which can further improve the testing efficiency and the practicality of the device, and realize non-destructive testing of plugs and sockets through the small current output of the built-in storage device, which can effectively solve the problems in the background technology.
