Abstract
The utility model discloses a cylinder cover. The cylinder cover is mainly a cuboid plate, vertically-communicated installation holes are formed in four corners of the cuboid plate, and the lower bottom face, where the lower ends of the installation holes are located, of the cuboid plate is an installation contact face. The cylinder cover is characterized in that sleeve-shaped bosses are arranged on installation hole positions of the lower bottom face of the cuboid rectangular plate, and the central axes of the sleeve-shaped bosses coincide with the central axes of the installation holes. According to the cylinder cover, the sleeve-shaped bosses are arranged on the installation hole positions of the lower bottom face of the cuboid plate, therefore, the sleeve-shaped bosses can be embedded in corresponding holes of components matched with the cuboid plate, bolts can penetrate through the installation holes and core portions of the sleeve-shaped bosses and be connected with the matched components, and the problem of leakage in the installation hole positions is solved.
Description
Technical field
The utility model relates to a kind of cylinder cap, especially a kind of cylinder cap of simple in structure, good seal performance.
Background technique
In the rail vehicles system, utilize hydraulic jack as power unit, utilize the corresponding moving element of action drives of oil cylinder to move, for this sealability to cylinder system requires very high.For the cylinder cap problem, the cylinder cap that adopts at present mostly is a rectangular sheet material, utilizes on the Qi Sijiao bolt in the mounting hole to realize being connected of cylinder cap and corresponding part, operates for a long time for this reason, just exists the problem of leakage at the position of mounting hole place.
The model utility content
Technical problem to be solved in the utility model provides a kind of cylinder cap, has characteristics simple in structure, good seal performance.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of cylinder cap, be mainly a cuboid sheet material, be distributed with the mounting hole of up/down perforation on four jiaos of the described cuboid sheet materials, the bottom surface of the cuboid sheet material at place, described mounting hole lower end is for installing surface of contact, its innovative point is: described cuboid sheet material bottom surface position of mounting hole place is provided with the sleeve-shaped boss, described sleeve-shaped boss central axis and mounting hole central axes.
Further, described sleeve-shaped boss internal surface is concordant with the mounting hole internal surface.
Further, have the groove consistent with rectangular sheet material frame structure on the described rectangular sheet material bottom surface, the nearly sleeve-shaped boss of described groove four corner connections.
The invention has the advantages that: by at rectangular sheet material bottom surface position of mounting hole place the sleeve-shaped boss being set, thereby so that this sleeve-shaped boss is embedded in the respective aperture of the parts that cooperate with rectangular sheet material, thereby bolt passes mounting hole to be connected with component with sleeve-shaped boss core, thereby has solved the problem that leak the pilot hole position.
Have the groove consistent with rectangular sheet material frame structure at rectangular sheet material bottom surface, and the nearly sleeve-shaped boss of groove four corner connections, thereby satisfying in the situation of usage requirement, saved raw material.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the plan view of a kind of cylinder cap of the utility model.
Fig. 2 is the worm's eye view of a kind of cylinder cap of the utility model.
Embodiment
Cylinder cap illustrated in figures 1 and 2 comprises bottom surface 3, sleeve-shaped boss 4, the groove 5 of cuboid sheet material 1, mounting hole 2, cuboid sheet material.
Cylinder cap of the present utility model is mainly a cuboid sheet material 1, is distributed with the mounting hole 2 of up/down perforation on 1 four jiaos of this cuboid sheet materials, and the bottom surface 3 of the cuboid sheet material at place, mounting hole 2 lower end is for installing surface of contact.For strengthening the sealability at position of mounting hole place, be provided with sleeve-shaped boss 4, these sleeve-shaped boss 4 central axis and mounting hole 2 central axes in bottom surface 3 mounting holes 2 positions of cuboid sheet material.
For ease of processing and fabricating, sleeve-shaped boss 4 internal surfaces and mounting hole 2 internal surfaces are kept concordant.
Satisfying in the situation of usage requirement, in line with the consideration of having saved raw material, have the groove 5 consistent with rectangular sheet material 1 frame structure, the nearly sleeve-shaped boss 4 of these groove 5 four corner connections at the bottom surface 3 of rectangular sheet material.
