Technical Field

[0001] The utility model relates to the technical field of piston rod slag cleaning, in particular to a slag cleaning, filtering and dust-proof component of a piston rod. Background Art

[0002] With the development of modern industry, hydraulic cylinders have been widely used and developed in many industries around the world. They have simple structure and reliable operation, and are the main actuators that are widely used in hydraulic systems.

[0003] At present, most hydraulic cylinder failures are caused by contamination of the working medium, and most of the contaminants are invaded by the external environment. The reciprocating process of the piston rod of the hydraulic cylinder is the main link for the invasion of external contaminants. The existing piston rod slag cleaning and dust prevention mainly involves setting a dust ring on the piston rod.

[0004] Setting up a dustproof ring can play a certain role in clearing slag and preventing dust, but its effect is general and the dustproof ring can usually only be adapted to piston rods of fixed sizes, has poor applicability and is inconvenient to replace. Utility Model Content

[0007] A piston rod slag filtering and dust prevention component, characterized in that it includes a mounting plate, a fixing bracket fixedly provided on one side of the mounting plate, a spacing adjustment component provided on the fixing bracket, and the spacing adjustment component is used to adjust the spacing between two matching blocks. The two matching blocks are symmetrically arranged and can be moved to fit the surface of the piston rod to prevent solid debris from adhering to the piston rod.

[0008] As a further limitation of the present technical solution, the spacing adjustment component includes a driving member and a movable member, the movable member includes two moving blocks, the two moving blocks are symmetrically slidably arranged on the fixed frame, each of the moving blocks is fixedly connected to the corresponding matching block through a connecting column, one end of the connecting column is rotatably connected to one end of the corresponding connecting rod, the other end of each connecting rod is rotatably connected to the two ends of the straight rod, the central axis of the straight rod is rotatably connected to the fixed frame, and the driving member is used to drive the central axis of the straight rod to rotate.

[0009] As a further limitation of the present technical solution, the driving member includes a worm wheel and a worm, the worm wheel is coaxially fixedly connected to the central axis of the straight rod, the worm engages the worm wheel and is rotatably connected to the fixed frame, and the fixed frame is also threaded with a top screw for supporting the central axis of the straight rod.

[0010] As a further limitation of the present technical solution, one side of the matching block has a groove, and adsorption cotton is detachably provided in the groove.

[0011] As a further limitation of the present technical solution, the oil-absorbing cotton block is provided with a through hole, the matching block is provided with a corresponding threaded hole, a threaded rod is threadedly connected to the threaded hole, and the threaded rod can extend into the corresponding through hole.

[0012] Compared with the prior art, the advantages and positive effects of the present invention are:

[0013] A spacing adjustment component is set up. When the worm is rotated, the worm drives the worm wheel engaged with it to rotate, the worm wheel drives the straight rod to rotate, the straight rod drives the two connecting rods to move, the connecting rod drives the corresponding moving blocks to move, and the moving blocks drive the corresponding matching blocks and adsorption cotton to move through the connecting column. The two matching blocks move symmetrically and drive the adsorption cotton to fit the outside of the piston rod, thereby adapting to piston rods of different sizes.
