Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic oil cylinders, in particular to a hydraulic oil cylinder device which is easy to install. Background Art

[0002] Hydraulic cylinder, also known as 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 using it to achieve reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the motion is smooth, so it is widely used in the hydraulic systems of various machines. The output force of the hydraulic cylinder is proportional to the effective area of ​​the piston and the pressure difference on both sides; the hydraulic cylinder is basically composed of a cylinder barrel and a cylinder head, a piston and a piston rod, a sealing device, a buffer device and an exhaust device. The buffer device and the exhaust device depend on the specific application occasion, and other devices are indispensable. The structural forms of hydraulic cylinders are diverse, and there are also many ways to classify them: according to the movement mode, they can be divided into linear reciprocating motion type and rotary swing type; according to the condition of receiving hydraulic pressure, they can be divided into single-acting type and double-acting type; according to the structural form, they can be divided into piston type, plunger type, multi-stage telescopic sleeve type, gear rack type, etc.

[0003] At present, when the hydraulic cylinders on the market are in use, it is necessary to connect the connecting parts and the output connecting ends of the hydraulic cylinders with bolts. In actual use, when the hydraulic cylinders and the connecting parts are installed, a connecting circular ring head is usually welded on the output end of the hydraulic cylinder, and then the circular hole on the connecting part and the connecting circular ring head are connected through subsequent connecting bolts. When the diameter of the circular hole on the connecting part is larger or smaller than the diameter of the connecting circular ring head, the hydraulic cylinder and the connecting part cannot be effectively connected and fixed, which makes the installation of the hydraulic cylinder more inconvenient.

[0024] In a preferred embodiment, a connecting head 12 is fixedly connected to the outer wall of the mounting block 9 away from the mounting groove 4, and a rotating rod 13 is provided inside the disassembly groove 3. One end of the rotating rod 13 passes through the outer wall of the entry and exit rod 2 and the rotating rod 13 is rotatably connected to the entry and exit rod 2. When the pressure block 7 moves, the pressure block 7 will drive the movable plate 6 to move, so that the movable plate 6 moves inside the disassembly groove 3.

When one end of the positioning block 8 is separated from the positioning groove 10, the connecting head 12 is pulled at this time, so that the connecting head 12 drives the installation block 9 to move, so that the installation block 9 is moved out from the inside of the installation groove 4, and the adaptive connecting head 12 drives the installation block 9 to move, so that the installation block 9 enters the inside of the installation groove 4. At this time, the rotating rod 13 is reversed to make the roller 16 away from the pressure block 7. At this time, the elastic force of the spring 11 enables the movable plate 6 to drive the positioning block 8 to enter the inside of the positioning groove 10, so that the device can be adaptively replaced with the connecting head 12 for connection and installation.
