By above description, can find, the cylinder that the utility model provides can first be fixed on axle sleeve on mould when mounted, and then the cylinder body with guide sleeve structure is directly plugged on axle sleeve, in concrete grafting process, first pull overcoat, after axle sleeve inserts in inner sleeve, unclamp overcoat, spring reset, the ball in inner sleeve can with axle sleeve on groove clamping.When needs are dismantled, by pulling overcoat, when axle sleeve is when moving away from cylinder body direction, under the effect of axle sleeve, the ball that ball moves in overcoat is given up the throne in groove, realizes the separated of inner sleeve and axle sleeve.Mount and dismount all very conveniently, avoided rotating in small space with the cylinder of air pipe.
Evenly and be convenient to rotation described inner sleeve and overcoat are cylindrical shape for stressed, and described cylinder body is threaded connection interior and puts, and the cylindrical structural that described axle sleeve is hollow is provided with outside thread at the other end of axle sleeve.
For the ease of the gas in foam mold, discharge, be connected with exhaust pin on described cylinder body, this exhaust pin passes described guide sleeve structure and stretches in described axle sleeve.
Overcoat is put to ejection from interior when preventing that spring from giving up the throne, on the outer wall of described inner sleeve near described axle sleeve one end, be provided with back-up ring.
In order better to realize the cooperation between inner sleeve and overcoat, boss on described outer wall of inside race is arranged to circular, inwall at described overcoat is also provided with circular flange collar, while putting in overcoat is socketed in, the boss on outer wall of inside race and the flange collar on outer casing inner wall surround the installation chamber of described spring.
For the ease of the artificial overcoat that grips, the outer surface of described overcoat is set to have the non slip surface of concavo-convex profile, stressed like this convenience, and installation and removal are also very easy to.
Remarkable result of the present utility model is: simple in structure, easy to assembly, made one-piece cylinder structure into guiding sleeve type Placement, when cylinder is installed, axle sleeve can be installed separately in advance, the mode that cylinder block is pegged graft by guide pin bushing with axle sleeve is again connected, avoided rotating in small space with the cylinder of air pipe, mount and dismount all very conveniently, improved working efficiency.
