Abstract
The utility model discloses a parking cylinder block, which comprises a cylinder shell of which the right side end part is not sealed. The parking cylinder block is characterized in that the position on the excircle face of the cylinder shell, near the right side end part of the cylinder shell, is provided with a mounting plate of which the cross section is approximate to a quadrangle; a certain distance exists between the right side face of the mounting plate and the right side end part of the cylinder shell; four corners of the mounting plate are respectively provided with a connecting hole. The position on the excircle face of the cylinder shell, near the right side end part of the cylinder shell of which the side end part is not sealed, is provided with the mounting plate, and the certain distance exists between the right side face of the mounting plate and the right side end face of the cylinder shell, and therefore, when installation is performed, the right side end part of the cylinder shell exceeds the right side face part of the mounting plate, and is embedded into a part matched with the cylinder shell, so that the sealing property of the cylinder block is improved.
Description
Technical field
The utility model relates to a kind of cylinder cylinder body of parking, especially a kind of good seal performance park the cylinder cylinder body.
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, the to-and-fro motion of the piston by being placed in hydraulic jack, for single unit system provides driving.Hydraulic jack is comprised of cylinder body and cylinder cap, at present general is to be placed in cylinder body one side end by cylinder cap, the mounting plate bolt of the periphery by the mounting plate by the periphery of cylinder body upper end portion and cylinder cap end, but do like this because be installed on cylinder body respective side end face concordant, thereby in the bolt connecting hole position, will there is the problem of leakage, consider the cylinder body of a kind of good seal performance of research for this reason.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of cylinder cylinder body of parking, and has the characteristics of good seal performance.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of cylinder cylinder body of parking, the cylindrical body housing that comprises a right-hand end open-ended, it is characterized in that: near its right-hand end position, be provided with the approximate tetragonal mounting plate in cross section on the external disc of described cylinder case, between described mounting plate right flank and cylindrical body housing right-hand end, certain distance is arranged, and have attachment hole on four jiaos of described mounting plates.
Further, on the left side of described cylindrical body housing, be symmetrically arranged with bearing.
Further, on the left side of described cylindrical body housing, have the turnover oilhole, on the cylindrical body housing left side at described turnover oil-hole location place, be provided with the hollow cylinder body structure, described hollow cylinder structure centre axis and this turnover oilhole central axis are perpendicular, and the hole of described hollow cylinder structure core and this turnover oilhole UNICOM.
Advantage of the present utility model is: by mounting plate being arranged near having on the external disc of cylinder case of side end open-ended, and between this mounting plate right flank and cylindrical body housing its right end face, certain distance is arranged, thereby when mounted, make cylindrical body housing right-hand end exceed mounting plate right flank part, be embedded in the component that coordinate with the cylindrical body housing, thus the sealability of raising cylinder body.
By on the left side parking the cylinder cylinder body, being symmetrically arranged with bearing, thereby, when cylinder body is vertically placed, utilize bearing to land.In addition, park on cylinder cylinder body left side and have the turnover oilhole, parking on cylinder cylinder body left side of this turnover oil-hole location place is provided with the hollow cylinder body structure, hollow cylinder structure centre axis and this turnover oilhole central axis are perpendicular, and the hole of hollow cylinder structure core and this turnover oilhole UNICOM, exist thereby reduce turnover oil-hole location place the risk of revealing.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is a kind of plan view of parking the cylinder cylinder body of the utility model.
Fig. 2 is a kind of left view of parking the cylinder cylinder body of the utility model.
Fig. 3 is a kind of plan view of parking the cylinder cylinder body of the utility model.
Embodiment
Fig. 1 is to the shown in Figure 3 left side 9 that the cylinder cylinder body comprises cylindrical body housing 1, the external disc 2 of cylinder case, mounting plate 3, cylindrical body housing right-hand end 4, attachment hole 5, bearing 6, turnover oilhole 7, hollow cylinder body structure 8, cylindrical body housing of parking.
Of the present utility modelly park the cylindrical body housing 1 that the cylinder cylinder body is a right-hand end open-ended, on the external disc 2 of cylinder case, be provided with the approximate tetragonal mounting plate 3 in cross section near its right-hand end position, these mounting plate 3 right flanks and 4 of cylindrical body housing right-hand end have certain distance, and on 3 four jiaos of mounting plates, have attachment hole 5, be convenient to park the cylinder cylinder body and be connected with the parts that match.
By on the left side 9 at the cylindrical body housing, being symmetrically arranged with bearing 6, thereby, when cylinder body is vertically placed, utilize bearing 6 to land.In addition, on the left side 9 of cylindrical body housing, have turnover oilhole 7, on the left side 9 of the cylindrical body housing of these turnover oilhole 7 positions, be provided with hollow cylinder body structure 8, these hollow cylinder body structure 8 central axis and this turnover oilhole 7 central axis are perpendicular, and the hole of hollow cylinder body structure 8 cores and this turnover oilhole 7 UNICOMs, adopt this structure, have thereby reduce turnover oilhole 7 positions the risk of revealing.
