A modular controllable delay trigger device

Abstract

The invention discloses a controllable modular time-delay trigger device. In an insulating shell, a spring cap, a spring, a safety pin, an insulating drawing wire, a fusible alloy, and a positive electrode contact are sequentially connected. The modular design is used to start the trigger. The spring cap is connected to the upper end cap of the spring. The spring is elongated by turning the cap to store force. The cap is equipped with a scale, and the elongation of the spring is controlled by rotation. The tension of the spring can be controlled by the rotation angle of the screw cap to determine the time when the creep displacement of the fusible alloy increases to contact with the positive metal sleeve, so as to achieve the purpose of controllable trigger time. When the safety pin is pulled out, the fusible alloy creeps and deforms under the tension of the spring connected by the insulating wire, but the creep displacement increases to the point where the circuit forms a path when it contacts the positive metal sleeve, and then triggers.

Description

technical field [0001] The invention relates to the technical field of industrial delay trigger devices, in particular to a modular controllable delay trigger device. Background technique [0002] In the current industrial production, sometimes a delay trigger device is needed to achieve the purpose of production, such as a delay detonation device, a device for periodic maintenance of equipment, etc. At present, there are few types of time delay devices, most of which are electronic delay devices, which are triggered by setting the time, and electronic equipment has high requirements for the working environment, and it is easy to appear short circuit, open circuit and other forms when used in humid, dusty and other environments invalidated. The mechanical device has relatively low requirements on the working environment, and is not affected by the power loss of the device for a long time. It has the advantages of simple structure and stable operation. [0003] Fusible allo...
