Abstract
Description
Technical Field
[0001] This utility model relates to the field of dual power supply detection technology, specifically to a semi-automatic detection fixture for dual power supply transfer switches. Background Technology
[0002] The existing dual-power production line and product testing are carried out in separate areas. Products have to be sorted from the production line to product turnover boxes before being sent to testing. Testing requires taking the products out of the product turnover boxes, testing them, and then putting them back. This results in transportation costs and time-consuming and labor-intensive handling by employees. In addition, dual-power transfer switches are mostly tested manually. During testing, there is a risk of accidental contact because the conductive parts are exposed. Utility Model Content
[0003] The technical problem this invention aims to solve is to overcome the shortcomings of existing technologies, such as the risk of accidental contact with conductive parts, inconvenience in product handling, and high production costs, thereby providing a mobile, easy-to-use, and highly efficient semi-automatic testing fixture for dual-power transfer switches.
[0004] Therefore, this utility model provides a semi-automatic testing fixture for a dual power transfer switch, comprising: a workbench; a first baffle, vertically disposed on the workbench, the inner side of the first baffle having a first electrode that contacts and connects to the wiring terminal on one side of the dual power transfer switch; an inverted L-shaped cover plate assembly, comprising an integrally connected cover plate and a second baffle, the cover plate being horizontally disposed on the workbench, and its end away from the second baffle being hinged to the top of the first baffle, the second baffle being disposed opposite to the first baffle, and its inner side having a second electrode that contacts and connects to the wiring terminal on the other side of the dual power transfer switch, the bottom outer side of the second baffle having a buckle plate; and an inverted L-shaped reverse buckle, movably mounted on the workbench, having a buckle groove for the buckle plate to be inserted, the reverse buckle having a locking position for engaging with the buckle plate and an unlocking position for disengaging from the buckle plate.
[0005] The inner wall of the cover plate is provided with a pressure block for the top of the dual power transfer switch to abut against it.
[0006] The top surface of the workbench is provided with a first stop bar and a second stop bar arranged in an L-shape, and the first stop bar and the second stop bar abut against the bottom of the dual power supply changeover switch.
[0007] The second baffle has a handle on its outer side.
[0008] The outer side of the buckle is fixed with an outwardly extending screw.
[0009] The workbench is mounted on a mobile trolley.
[0010] The technical solution of this utility model has the following advantages:
