Description

Structure for freely limiting power supply of detector Technical Field The utility model relates to the technical field of detector accessories, in particular to a structure for enabling a detector to freely limit power supply. Background With the time progress, the variety of observation detection record instruments is increased, such as night vision devices, thermal imaging, audio and video recorders, telescopes and glasses, in practical application, a rotatable lens barrel scheme (namely lens barrel rollover) has more reasonable gravity center distribution, when the lens barrel is not in operation, a manual rapid rollover lens barrel is stored to reduce the shielding view, one side of the observation lens of the night vision device is freely used, the other side of the observation lens barrel is stored to be convenient for visual observation, when the lens barrel is in rollover, although a user does not need to work the rollover lens barrel at the moment, the whole night vision device is powered all the way, the power supply cannot be stopped freely aiming at a certain lens barrel, and when the rollover state is considered, the lens barrel is free to be closed, so that the light exposure is avoided, the burning risk of an image intensifier is reduced, the service life is saved, and the electronic limiting structure is further used for protection. The current limiting structure in the prior art generally adopts conductor motion contact power-on, an attitude sensor control circuit or magnetic force automatic power-off, wherein the magnetic force automatic power-off application is the most extensive, magnets are arranged on two sides below the machine, when the magnets are downwards turned close to a main body, a built-in switch is connected with a power supply, two sides of the built-in switch are far away from the main body when the magnets are turned down, the power supply is kept off, and the power supply is automatically powered on when the built-in switch is normally kept off and downwards turned down, but under the design, when the activation condition is absent, such as the magnets are lost, the built-in switch cannot work at all no matter the side is turned down, and certain limitation exists.
