Description

Loader hydro-cylinder scale fixing device Technical Field The utility model relates to the technical field of bucket oil cylinders of engineering machinery, in particular to a loader oil cylinder staff gauge fixing device. Background The main function of the bucket cylinder of the loader is to provide power to help the bucket to finish various actions, when an operator controls the bucket in a cab, the expansion and contraction amount of the cylinder is not easy to observe, the bucket is easy to suddenly rise, fall or incline excessively, in addition, in the movement process of the bucket, bulk materials in the bucket are easy to spill, if the material is scattered to adhere or scratch a piston rod of the cylinder, oil leakage of the cylinder is easy to cause, and the bucket cannot move. Disclosure of utility model The utility model aims to overcome the defects in the prior art and provides a device for fixing a scale of a loader oil cylinder. The utility model discloses a loading engine oil cylinder staff gauge fixing device for achieving the purpose, which comprises an oil rod seat connected to the end part of an oil cylinder piston rod, a staff gauge and a supporting seat, wherein two ends of the supporting seat are detachably connected with the oil rod seat and the staff gauge respectively, and one end of the staff gauge extends and is covered above the oil cylinder piston rod. Preferably, the oil rod seat is provided with at least one threaded hole at one side close to the supporting seat. Preferably, the supporting seat is provided with a through hole matched with the threaded hole, and the through hole penetrates through the supporting seat body for the bolt to pass through. Preferably, the scale is provided with a round hole matched with the through hole, and the scale, the supporting seat and the oil rod seat are connected through bolts. Preferably, the oil rod seat is provided with at least one first positioning hole at one side close to the supporting seat. Preferably, the support seat is provided with a first convex column which is embedded into the first positioning hole and is matched with the aperture of the first convex column on one side close to the oil rod seat. Preferably, the support seat is provided with a second convex column at one side close to the scale, and the scale is provided with a second positioning hole which is used for the second convex column to penetrate and adapt to the shape of the second convex column. Preferably, the supporting seat is made of plastic, and the staff gauge is made of stainless steel. The beneficial effects of the utility model are as follows: 1. According to the device, through improving the oil rod seat structure of the oil cylinder, the supporting seat and the scale are detachably connected to the oil rod seat, when an operator controls the bucket in the cab, the device moves in a telescopic mode along with the oil cylinder piston rod, the operator uses the scale as a reference object through observing the scale, the movement speed of the bucket is controlled more accurately, and the situation that the bucket suddenly rises, descends or tilts excessively due to sudden large-scale expansion of the oil cylinder piston rod is avoided. 2. The scale extends to the cylinder piston rod top, when the bulk cargo is unrestrained, can protect the cylinder piston rod, avoid the cylinder piston rod adhesion bulk cargo or by the fish tail, cause the oil to reveal in the hydro-cylinder. 3. The device adopts a detachable structure, is stronger in applicability aiming at supporting seats with different heights and scales with different lengths and widths of different oil cylinders, and has low manufacturing and replacement cost compared with an integrated structure.
