Description
Technical field:
The utility model relates to machinery fields, and in particular to a kind of fixed turgor cylinder mandrel.
Background technique:
Oil cylinder mandrel used all uses rubber ring as tensioning ring currently on the market, and rubber ring is easy aging, rubber ring
Elasticity it is big, but the tightening dynamics of rubber ring is smaller, and the tightening active force played to the port of oil cylinder mandrel is small.And rubber ring
After aging, tensioning ring is needed replacing, is replaced after needing to dismantle oil cylinder.Since rubber ring aging is fast, it is easy breakage,
It needs frequently to be replaced, increases work difficulty and labor intensity.And the port of oil cylinder mandrel in the market is three
A notch under the tightening of rubber ring, is difficult to restore after oil cylinder mandrel spreading, and the utility model provides a kind of fixed rise
Locking oil cylinder mandrel.
Utility model content:
The technical problem to be solved by the utility model is to provide a kind of fixed turgor cylinder mandrels.
The following technical solution is employed for technical problem to be solved in the utility model to realize: a kind of fixed tensioner oil
Cylinder mandrel, including mandrel rod, the left pivot movement of the mandrel rod are connected with four groups of connecting plates, offer on the outside of the connecting plate
The outside of screw thread, the connecting plate is connected with screw shell by screw thread, and the outside of the screw shell is socketed with sleeve,
The inner wall of the sleeve is fixedly connected with the first pawl, and the outer wall of the screw shell is fixedly connected with the second pawl, and described
One pawl and the second pawl are staggeredly clamped, and the outer wall of the sleeve is fixedly connected with connecting key, is rotatablely connected on the connecting key
There is L shape card key, the bottom of the L shape card key is fixedly connected with buckle, and the left part outer wall of the mandrel rod offers card slot, described
Buckle is clamped with card slot activity.
Preferably, the inner wall of the connecting plate is fixedly connected with rubber pad.
Preferably, the outer wall of the mandrel rod is fixedly connected with retaining ring.
Preferably, the L shape card key is provided with four groups.
Preferably, the left end of the mandrel rod is fixedly connected with limited block.
Preferably, the limited block is located at the inside of connecting plate.
The beneficial effects of the utility model are: the utility model connection when by connecting plate package and connected tube outside
Portion, turnbarrel, the clamping between the first pawl and the second pawl play the role of single direction rotation, turnbarrel band counterclockwise
Dynamic screw shell is mobile to connecting plate left part by screw thread, and the rubber in connecting plate plays the role of protection, plays to connecting plate
Fixed effect adjusts the position of sleeve clockwise, is clamped L shape card key by buckle and card slot activity, plays secondary positioning
Effect, the port of oil cylinder mandrel is tightened, is effectively controlled mandrel port spreading degree in the running, and in spreading
After can carry out tightening recovery, application easy to spread in time.
