An alarm device and method for preventing a gas spring anti-drop rod from being pressurized

Abstract

The invention discloses a device and method for preventing stress alarm of an anti-falling rod for a gas spring. The device comprises the anti-falling rod. The lower side surface of the anti-falling rod is of a rectangular tube shape with an opening. The upper side of the anti-falling rod is fixed with a stress alarm device through a screw. The stress alarm device is composed of a power supply module, a displacement detection module and an alarm module. The power supply module is used for raising an alarm for the overall stress alarm device. The displacement detection module is used for detecting displacement amount and sending related information to the alarm module. An alarm method is realized based on the alarm device. Compared with the prior art, the device and method for preventing stress alarm of the anti-falling rod for the gas spring have following beneficial effects: the device and method can be applied to a self-service product of a financial terminal and used for decompression failure of the gas spring and stress alarm of the anti-falling rod for the gas spring; an operator is prompted to replace the gas spring or unlock the anti-falling rod so that potential safety hazards for the operator are avoided; high safety is obtained; flexibility of the self-service terminal is effectively improved; competitiveness is enhanced; and the device is more personalized and highly practical.

Description

technical field [0001] The invention relates to the technical field of financial terminal equipment, in particular to a highly practical alarm device and method for preventing the pressure of a gas spring anti-drop bar. Background technique [0002] With the expansion of the scale of the bank, the demand for self-service equipment is also increasing, and the application of power-assisting devices-gas springs on self-service equipment is also increasing, which is used to support the upper cover of the equipment. Gas spring is an industrial accessory that can support, buffer, brake, height adjust and angle adjust. The disadvantage of the component is that it is easy to leak air and cause sudden failure due to pressure relief after a long time, which brings safety hazards to the operator; in order to prevent the gas spring from suddenly failing, a gas spring anti-drop lever is added: when the gas spring suddenly fails, the gas spring prevents The drop bar is against the end fa...

Gas spring is an industrial accessory that can support, buffer, brake, height adjust and angle adjust. The disadvantage of the component is that it is easy to leak air after a long time, and cause sudden failure due to pressure relief, which brings safety hazards to the operator; in order to prevent the gas spring from suddenly failing, a gas spring anti-drop lever is added: when the gas spring suddenly fails, the gas spring prevents The drop bar is against the end face of the outer cylinder wall of the gas spring to prevent safety accidents caused by sudden failure; this brings another problem: when the operator closes the upper cover of the self-service terminal, he often forgets to unlock the anti-drop bar and presses down on the upper cover forcefully , causing deformation and damage to the upper cover or box body
