Abstract
The utility model discloses a sealing protection device at the end of an automobile brake pipe, which comprises a pipe nut, a brake pipe and a blanking cap at the end of the brake pipe. An opening part of the blanking cap at the end of the brake pipe is arranged into a shape like a Chinese character 'Tu' downwards; a front drum type upset head of the brake pipe passes through the tail end of the pipe nut; the blanking cap is sleeved on the outer wall of the pipe nut from the front drum type upset head of the brake pipe downwards; the lateral wall of the blanking cap is jointed with threads of the pipe nut; and a cone-shaped plug placed into the opening part of the front drum type upset head is also arranged at the joint of the lateral wall at the bottom end of the blanking cap and the opening part of the front drum type upset head of the brake pipe. By adopting the scheme, after the blanking cap is assembled, the cone-shaped plug is just squeezed into the opening part of the front drum type upset head; isolating air and impurities enter into the brake pipe to keep clean inner wall of the automobile brake pipe and ensure normal work of a pressure pump and safe automobile driving; anti-drop annular bulges are arranged on the inner wall of the blanking cap at the end of the brake pipe and on the outer sides of the threads at the head of the pipe nut; and the blanking cap is stably clamped with the outer wall of the nut, so that the drop is avoided after the blanking cap at the end of the brake pipe is mounted.
