Description
Technical field
The utility model relates to hydraulic equipment, particularly relates to oil cylinder.
Background technique
Oil cylinder and oil hydraulic cylinder, oil hydraulic cylinder is the straight line moving type executive component that the pressure reduction on ouput force and piston effective area and both sides thereof is directly proportional.Cylinder piston rod at work, is directly fixedly connected with the mechanical part that will drive by piston rod, and both are often through being threaded; But, in transport, in operating process, easily cause the colliding with of piston rod, damage, affect the reliability of cylinder action.
Model utility content
The utility model, for above problem, provides a kind of structure simple, and convenient processing, improves the oil cylinder of cylinder efficient reliability.
The technical solution of the utility model is: comprise cylinder body, piston and piston rod, and described cylinder body has holding cavity, and described piston rod is located in the holding cavity of described cylinder body by piston; Also comprise rubber sleeve, one end of described cylinder body is provided with the boss with mesopore, and described piston rod is actively installed in the mesopore of described boss;
The end that described piston rod stretches out described cylinder body is provided with outside thread and end face is provided with groove,
Described rubber sleeve has mesopore and is set on described piston rod, and the bottom surface of the mesopore of described rubber sleeve is provided with the block rubber consistent with described groove, and the end face of described rubber sleeve is towards the outside thread of described piston rod.
Described groove is straight groove or cross recess.
The utility model is provided with boss on cylinder body, is convenient to the guiding to piston rod, plays the effect of protection piston rod; On the piston rod sheathed by rubber sleeve, avoid the colliding with of piston rod, damage, the block rubber in rubber sleeve is located in the groove of piston rod end face, improves the reliability that both connect; In work, by the outside thread on piston rod and other assemblies, realize connecting.The utility model is easy to operate, structural stability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the structural representation one of piston rod end face in the utility model,
Fig. 3 is the structural representation two of piston rod end face in the utility model;
In figure, 1 is cylinder body, and 2 is piston rods, and 20 is grooves, and 201 is straight groovees, and 202 is cross recesses, and 3 is boss, and 4 is rubber sleeves, and 40 is block rubbers, and 5 is outside threads.
Embodiment
The utility model as Figure 1-3, comprises cylinder body 1, piston and piston rod 2, and described cylinder body 1 has holding cavity, and described piston rod 2 is located in the holding cavity of described cylinder body 1 by piston; Also comprise rubber sleeve 4, one end of described cylinder body 1 is provided with the boss 3 with mesopore, and described piston rod 2 is actively installed in the mesopore of described boss 3;
The end that described piston rod 2 stretches out described cylinder body is provided with outside thread 5 and end face is provided with groove 20,
Described rubber sleeve 4 has mesopore and is set on described piston rod 2, and the bottom surface of the mesopore of described rubber sleeve 4 is provided with the block rubber 40 consistent with described groove 20, and the end face of described rubber sleeve 4 is towards the outside thread of described piston rod 2; Rubber sleeve at work, according to work on the spot situation, detachably or is not dismantled and is carried out being threaded of piston rod and other assemblies.
As Figure 2-3, described groove 20 is straight groove 201 or cross recess 202, is convenient to select according to processing, improves the reliability be connected with rubber sleeve.
