The invention relates to the technical field of automobile parts, in particular to a rubber protective sleeve of an automobile rubber brake hose, and belongs to energy-saving and cost-reducing safety protection.The rubber protective sleeve is characterized in that after a conical expander is taken out, a worker manually resets a telescopic ring, and after the telescopic ring is reset, an elastic piece on the telescopic ring can drive a telescopic block to retract into a trapezoidal groove; in this way, compared with the prior art, when the rubber protective sleeve body is expanded, the problem that the rubber protective sleeve body is extruded by the upper end, and the rubber protective sleeve body deforms due to extrusion is solved, and on the other hand, when the rubber protective sleeve body moves downwards when the conical expander moves downwards, the rubber protective sleeve body is not extruded by the upper end. And the rubber protective sleeve body does not generate friction with the conical expander body, so that the reject ratio of the rubber protective sleeve body during production is reduced.
本发明涉及汽车零件技术领域,汽车橡胶制动软管的橡胶保护套,属于节能,降本安全防护,包括:当锥形扩张器取出后,工作人员通过手动将伸缩环进行复位,伸缩环复位后,伸缩环上的弹性片会带动伸缩块收缩至梯形槽内;这样相对与现有技术中的橡胶保护套本体在进行扩张时,橡胶保护套本体不会出现受上端挤压,出现橡胶保护套本体发生挤压形变的问题,另一方面,橡胶保护套本体在锥形扩张器向下方进行运动时,橡胶保护套本体不会与锥形扩张器本体产生摩擦,进而降低橡胶保护套本体生产时的不良率。
