Technical Field

[0001] The utility model relates to the technical field of explosion-proof oil cylinders, in particular to a novel high-strength explosion-proof oil cylinder. Background Art

[0002] Oil cylinder generally refers to hydraulic cylinder. Hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swinging motion). It has a simple structure and reliable operation. When it is used to achieve reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap and the movement is smooth. Therefore, it is widely used in the hydraulic systems of various machines.

Cracks first appear on the inner wall of the cylinder barrel and then gradually develop outward. Moreover, the cracks are mostly distributed longitudinally or at a 45-degree angle to the inner wall generatrix, which is very prone to bursting risks. Therefore, it is necessary to design a new type of high-strength explosion-proof oil cylinder. Utility Model Content

When the cylinder 1 of the high-strength explosion-proof oil cylinder is subjected to a large pressure, the pressure inside the cylinder 1 gradually increases. The upper explosion-proof ring 21, the middle explosion-proof ring 22 and the lower explosion-proof ring 23 evenly distributed on the outer ring of the cylinder 1 share the pressure on the cylinder 1 in the first level, thereby improving the explosion-proof performance;
