The invention discloses a hose connecting
assembly and a hose
butt joint device. The hose connecting
assembly comprises a
pipe joint, a sealing ring, an opening
gasket and a cylindrical nut, the
pipe joint is provided with a sleeve and an inner
pipe extending out of the sleeve, a gap allowing a hose to be inserted is formed between the inner pipe and the sleeve, a first chamfer is arranged at the end part of the inner wall of the sleeve, the sealing ring is connected to a position outside the hose in a sleeving mode, the opening
gasket is connected to a position outside the hose in a sleeving mode, the first end face of the opening
gasket is abutted with the end part of the sleeve so as to abut against the sealing ring into the first chamfer, a plurality of protrusions which are distributed in the circumferential direction are arranged on the second end face of the opening gasket, the cylindrical nut is in threaded connection with the sleeve, the bottom wall of the cylindrical nut is suitable for abutting against the second end face and is provided with a center hole for the hose to penetrate through, and the hole wall of the center hole is provided with a second chamfer suitable for abutting against the protrusions and enabling the free ends of the protrusions to be inserted into the outer wall of the hose. The hose
butt joint device comprises the two hose connecting assemblies, wherein the inner pipes of the hose connecting assemblies are connected into a whole and communicate with each other. By the adoption of the scheme, a
silica gel ring can be flat and prevented from losing
efficacy, and the hose can be locked and prevented from being disengaged.
