Abstract

The invention discloses a testing control device. The testing control device comprises a casing (21), a driving shaft (22), a button (23), a locking slider (24), a first elastic member (25), an auxiliary part (26) and a second elastic member (27), the button (23) mounted on the casing (21) is pressed to push the auxiliary part (26) to move and trigger a testing signal switch to send a testing signal; the first elastic member (25) pushes the locking slider (24) to lock the button (23) at the position after the button (23) is pressed; the driving (22) mounted on the casing (21) is provided with a reset projection (221) which is used for pushing the locking slider (24) to reset when testing is finished and unlocking the button (23); and the second elastic member (27) is used for pushing the auxiliary part (26) to reset when the locking slider (24) is reset and pushing the button (23) to reset via the auxiliary part (26). The testing control device controls testing starting via the button, misoperation possibly existing via handle operation in the prior art is avoided, and reliability of testing control operation is improved.

Description

technical field

[0001] The invention relates to the technical field of testing, in particular to a testing control device. Background technique

[0002] Such as figure 1 As shown, in the prior art control device for implementing test control on equipment, the handle (Handle) 11 used for control operation has three position states: open position, closed position and test position. With this kind of control device, when the handle is rotated from the open position to the closed position, due to improper control of the rotation force, it is easy to cause the handle to go beyond the close position and rotate to the test position, resulting in some error signals and indications, which lead to The wrong operation is to start the test.

[0003] In order to avoid this kind of misoperation, an existing solution is to set a screw. When the screw is installed, the handle can only be rotated to the open position and the closed position. When the screw is removed, the user is allowed t...
