Abstract
The utility model provides a one-piece piston. The one-piece piston comprises a mounting surface and an operating surface opposite to the mounting surface, at least three bosses are arranged on the periphery of the one-piece piston, and an oil groove is formed between each two adjacent bosses. When the one-piece piston is mounted in a hydraulic cylinder, the boss arranged in the middle of the periphery of the one-piece piston can support the one-piece piston, so that an oil way of the oil groove cannot be blocked due to squeezing of the hydraulic cylinder. The one-piece piston made of polyurethane materials is higher in strength, oil-resistant, wear-resistant and longer in service life.
Description
Technical field
The utility model relates to the piston field, especially, relates to a kind of solid piston.
Background technique
On concrete pump, solid piston is installed.As shown in Figure 4, solid piston comprises attachment face 1 and the working surface 2 relative with attachment face.Attachment face 1 is provided with a plurality of installing blinds, is bolted on the concrete pump, and the outer ring of working surface 2 is provided with flange collar 3, and the two ends, outer peripheral surface ground of solid piston are respectively equipped with the first boss 4 and the second boss 5.Form oil groove 6 between the first boss 4 and the second boss 5.When being installed in this solid piston in the oil hydraulic cylinder, oil hydraulic cylinder can push the first boss 4 and the second boss 5, stops up oil groove 6, so that oil circuit is not smooth.Its used solid piston has nitrile rubber to make, because the physical property of nitrile rubber is poor, causes the oil resistant of solid piston, wear-resisting property not high.
The model utility content
The utility model purpose is to provide a kind of solid piston, with the easy obstruction of oil circuit of the solid piston that solves prior art and oil resistant, technical problem that wear-resisting property is not high.
For achieving the above object, according to an aspect of the present utility model, provide a kind of solid piston, comprised attachment face and the working surface relative with attachment face, the periphery circle of solid piston is provided with at least three boss, forms oil groove between every adjacent two boss.
Further, solid piston is cylindrical.
Further, attachment face is provided with tapped hole, and the outer ring of working surface is provided with flange collar.
Further, the two ends of the outer peripheral surface of solid piston are respectively equipped with the first boss and the second boss; The first boss is consistent with the height of the second boss.
Further, the centre of the excircle of solid piston is provided with the 3rd boss, forms the first oil groove between the first boss and the 3rd boss, forms the second oil groove between the second boss and the 3rd boss.
Further, solid piston is made by polyurethane material.
The utlity model has following beneficial effect: the utility model is than prior art, periphery circle at solid piston arranges at least three boss, in the time of in solid piston is installed in oil hydraulic cylinder, the boss that arranges in the middle of the periphery circle of solid piston can support solid piston, so that the oil circuit of oil groove can be owing to the extruding of oil hydraulic cylinder is stopped up.
And solid piston of the present utility model is made by polyurethane material, so that the strength increase of solid piston, and oil resistant is wear-resisting, has improved the working life of solid piston.
Except purpose described above, feature and advantage, the utility model also has other purpose, feature and advantage.The below is described in further detail the utility model with reference to figure.
Description of drawings
The accompanying drawing that consists of the application's a part is used to provide further understanding of the present utility model, and illustrative examples of the present utility model and explanation thereof are used for explaining the utility model, do not consist of improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of the solid piston of the utility model preferred embodiment;
Fig. 2 is the cross-sectional schematic of A-A shown in Figure 1;
Fig. 3 is the local enlarged diagram at B shown in Figure 2 place; And
Fig. 4 is the structural representation of the solid piston of prior art.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
Referring to Fig. 1 and Fig. 2, preferred embodiment of the present utility model provides a kind of solid piston, comprises attachment face 10 and the working surface 20 relative with attachment face 10, and the periphery circle of solid piston is provided with at least three boss, forms oil groove between every adjacent two boss.
Solid piston is cylindrical, and columniform both ends of the surface are respectively attachment face 10 and working surface 20, and attachment face 10 is provided with tapped hole, by bolt solid piston is fixed on the concrete pump.Working surface 20 is the end face relative with attachment face 10, and the outer ring of working surface 20 is provided with flange collar 21.The two ends of the outer peripheral surface of solid piston are respectively equipped with the first boss 41 and the second boss 42.Preferably, the first boss 41 is consistent with the height of the second boss 42.The madial wall of the madial wall of the first boss 41 and the second boss 42 is respectively the inclined-plane.The centre of the periphery disc of solid piston also is provided with a plurality of boss, so that the round-formed a plurality of oil grooves of the periphery of solid piston.Please in conjunction with referring to Fig. 3, in the present embodiment, the centre of the outer peripheral surface of solid piston is provided with and forms formation the second oil groove 32 between the first oil groove 31, the second boss 42 and the 3rd boss 43 between the 3rd boss 43, the first boss 41 and the 3rd boss 43.In the time of in solid piston is installed in oil hydraulic cylinder, the boss that arranges in the middle of the periphery of the solid piston circle can support solid piston, so that the oil circuit of oil groove can be owing to the extruding of oil hydraulic cylinder is stopped up.
Solid piston of the present utility model is made by polyurethane material, so that the strength increase of solid piston, and oil resistant is wear-resisting, has improved the working life of solid piston.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
