Spring end sleeve for mine protective screen throwing
The invention relates to a spring end sleeve for mine protective screen throwing. The spring end sleeve comprises a sleeve body. The front end face of the sleeve body is provided with an opening. The middle of the sleeve body is a cavity. The rear end of the sleeve body is provided with a blocking ring. The upper portion of the sleeve body is provided with a transverse supporting block. The left side and the right side of the front end face of the transverse supporting block are provided with two longitudinal supporting columns symmetrical relative to the median plane of the sleeve body in a left-right manner respectively. The middle of the upper end of the transverse supporting block is provided with a U-shaped support. The U-shaped support comprises two baffles arranged on the left side and the right side of the transverse supporting block respectively. The baffles are provided with pin holes. According to the spring end sleeve, an external spring is put into the sleeve body, and a lever device released by the control spring on the sleeve body is adopted to control ejection of a protective screen. The spring end sleeve is simple in structure and convenient to use; and manual operation is replaced, manpower is saved, labor intensity is lowered, and the ejection safety and ejection stability of the spring are guaranteed.
