The invention relates to an auxiliary support, in particular to the auxiliary support for broken
water pipe installing. According to the auxiliary support for the broken
water pipe installing, a connecting sleeve can be prevented from being loosened, and the connecting sleeve can be prevented from being easily installed over. The technical scheme of the auxiliary support for the broken water pipeinstalling comprises a base, a supporting rod, a compression cylinder, a
piston, a connecting block, a sliding sleeve, a sliding rod, a holding rod, an air inlet
pipe, an air outlet
pipe, a one-way valve and the like; the supporting rod and the compression cylinder are installed on the left side of the top of the base, the supporting rod is located on the right side of the compression cylinder, and the
piston is arranged in the compression cylinder; and the upper portion of the inner right side of the compression cylinder is connected to the connecting block, the sliding sleeve is installed onthe left side of the connecting block, the sliding rod is arranged in the sliding sleeve in a sliding mode, and the holding rod is installed at the top end of the sliding rod. According to the auxiliary support, an air bag is in contact with the inner wall of the
water pipe, residual water in the water
pipe can be prevented from flowing to glue to cause the glue to be invalid, so that the connecting sleeve is prevented from being loosened; and the move distance of the connecting sleeve to the right can be adjusted through a limiting mechanism, so that the connecting sleeve is prevented from moving to much to the right to influence the connection of the water pipe.
