Title:
ELECTRIC CYLINDER WITH DIAL VERIFICATION MECHANISM FOR CRIME PREVENTION
Document Type and Number:
Japanese Patent JP2021031999
Kind Code:
A
Abstract:
To provide an electric cylinder comprising a dial verification mechanism to a conventional electric cylinder, and provided with crime prevention measures which causes a timer to delay unlocking of the electric cylinder for a certain period of time, and causes a capacitor to perform a voltage supply only once even if there is no power supply.SOLUTION: In an electric cylinder with a dial verification mechanism for crime prevention according to the present invention, the dial verification mechanism is housed in a dial module, and is mounted in a main housing for installation. When a dial number is selected for setting to coincide with a set number using a dial number change lever, a lock plate moves in an arrowed direction, a limit switch mounted on a control panel above the dial module is turned on, resulting in that an electronic technology circuitry in the control panel brings the electric cylinder into a condition in ready for operation, and since the control panel has a timer function, outputting an active signal to the electric cylinder is prevented for a certain period of time even when the limit switch is turned on by dial verification.SELECTED DRAWING: Figure 3
