Modular controllable time-delay triggering device

Abstract

The invention discloses a modular controllable time-delay triggering device. In an insulating shell, a spring rotary cover, a spring, a safety pin, an insulating drawing wire, a fusible alloy and a positive contact are connected in sequence. The modularized design is adopted for starting and triggering, the spring rotary cover is connected with an upper end cover of the spring, and the spring is driven to extend to store force by rotating the rotary cover. Scales are arranged on the rotary cover, and the extension amount of the spring is controlled through rotation. The tensile force of the spring can be controlled through the rotation angle of the rotary cover, so that the time for increasing the creep displacement of the fusible alloy to be in contact with a positive electrode metal sleeve is determined, and the purpose of controllable triggering time is achieved. When the safety pin is pulled out, the fusible alloy generates creep deformation under the tension effect of the spring connected with the insulating wire, and when the creep displacement is increased to be in contact with the positive electrode metal sleeve, a circuit is formed, and then the triggering is achieved.

Description

Technical field [0001] The invention relates to the technical field of industrial time-delay trigger devices, in particular to a modular controllable time-delay trigger device. Background technique [0002] At present, in current industrial production, sometimes a delay trigger device is needed to achieve the purpose of production, such as a delay initiation device, a device for regular maintenance and so on. There are currently fewer types of time delay devices, most of which are electronic delay devices, which are triggered by setting the time. Electronic equipment has higher requirements on the working environment, and it is prone to short circuits and open circuits when used in humid, dusty and other environments. Invalidate. 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, and has the advantages of simple device structure and stable operation. [0003] Fusible alloy is a kin...
