Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic oil cylinders, in particular to a hydraulic oil cylinder with an explosion-proof function. Background Art

[0002] The hydraulic cylinder is a key component in the hydraulic system. Its main function is to convert hydraulic energy into mechanical energy. It generates linear speed and force by controlling the flow and pressure of the liquid, thereby realizing the movement and control of various machines. The application of hydraulic cylinders is very extensive. The basic structure of the hydraulic cylinder includes a cylinder body, a cylinder rod (piston rod), a sealing device, a buffer device and an exhaust device. Its working principle is based on Pascal's law. It realizes reciprocating motion by controlling the pressure of the liquid. The advantages of hydraulic cylinders include simple structure, reliable operation, the ability to eliminate the reduction device, no transmission gap, and smooth movement. Therefore, they are widely used in the hydraulic systems of various machines. When a small hydraulic cylinder is used, the upper and lower ends are usually connected to the object for rotation, making the hydraulic cylinder more flexible to use. The common small hydraulic cylinders on the market are usually made of steel. If inferior steel is used or there are defects in the production process, the strength of the cylinder will be insufficient, which will easily cause it to burst, and the explosion-proof effect is poor. In addition, when the hydraulic cylinder is hit by external force, it will also cause the hydraulic cylinder to burst. Utility Model Content

[0003] The disclosed embodiment relates to a hydraulic cylinder with explosion-proof function. Before the hydraulic cylinder body is used, it can be connected to the bottom structure, so that after the hydraulic cylinder body encounters a collision, the bottom end of the hydraulic cylinder body drives the moving part and the push plate structure to move inside the buffer groove, and squeezes the push plate structure made of elastic metal material. The elasticity of the push plate structure is used to eliminate the impact force, reduce the impact encountered by the hydraulic cylinder body, and reduce the probability of explosion. At the same time, the push plate structure is evenly arranged in a ring shape, which can buffer in multiple directions and buffer the impact in any direction.

[0004] In a first aspect of the present disclosure, a hydraulic cylinder with explosion-proof function is provided, specifically comprising: a hydraulic cylinder body; bolts are provided at the bottom of the hydraulic cylinder body, and two kits are mounted on the outside of the hydraulic cylinder body, and a ring-shaped pushing component is fixed to the bottom of each kit, and the cross-section of the pushing component is a triangular structure, and a reinforcement ring is welded to the outside of the ring-shaped pushing component; a bottom part structure; the bottom part structure is installed at the bottom of the hydraulic cylinder body, and a moving part is installed on the bottom part structure through a buffer groove, and a ring-shaped uniformly arranged pushing plate structure is welded to the outside of the moving part of the T-shaped shaft structure, and the pushing plate structure is made of elastic metal, and the top of the moving part is connected to the bolt.

[0005] In at least some embodiments, a side rod with an external thread is respectively provided on both sides of the hydraulic cylinder body, and an adjusting nut is installed on the outside of the side rod through a thread; two force-bearing components with an annular structure are welded and fixed to the outside of the hydraulic cylinder body, and the cross-section of the force-bearing components is a triangular structure and contacts the inner side of the pushing component, and the distance between the two force-bearing components is the same as the distance between the two kits; the two kits are welded and fixed by four connecting rods, and two pressure components are respectively provided on both sides of each kit, and the side rod is inserted into the interior of the pressure component, and the bottom of the adjusting nut contacts the top of the pressure component.

[0007] The utility model provides a hydraulic cylinder with explosion-proof function, which has the following beneficial effects:

[0008] After the hydraulic cylinder body is installed, the adjusting nut can be tightened to squeeze the pressure-bearing component and displace it, so that the two kits move downward at the same time. The kit makes sliding contact with the outside of the force-bearing component through the pushing component. Since the contact surface is an inclined structure, the pushing component generates an extruding and gathering force, thereby improving the strength of the hydraulic cylinder body from the outside and preventing the hydraulic cylinder body from bursting.

[0009] Before the hydraulic cylinder body is used, it can be connected to the bottom structure, so that after the hydraulic cylinder body encounters a collision, the bottom end of the hydraulic cylinder body drives the moving parts and the push plate structure to move inside the buffer groove, and squeezes the push plate structure made of elastic metal material. The elasticity of the push plate structure is used to eliminate the impact force, reduce the impact encountered by the hydraulic cylinder body, and reduce the probability of bursting. At the same time, the push plate structure is evenly arranged in a ring shape, which can buffer in multiple directions and buffer impacts in any direction.

[0010] After the connector is connected to the object through rotation, lubricating oil can be added to the inside of the side groove to allow the lubricating oil to penetrate into the inside of the contact piece. The contact piece controls the lubricating oil to flow slowly, which is convenient for adding to the outside of the object, making it easy to lubricate the rotating connection position and reducing the number of maintenance times.

The top of the moving part 202 is connected with bolts.
