Abstract
The utility model relates to a wall-flow type multi-sectional telescoping cylinder, which comprises an external cylinder sleeve, a top cover which is provided with an oil inlet and an oil outlet holes, and a piston. The utility model is characterized in that the internal side of the external cylinder sleeve is assembled with a middle cylinder sleeve in a sliding way; the internal side of the middle cylinder sleeve is assembled with the piston in a sliding way; the external cylinder sleeve and the end portion of the middle cylinder sleeve are provided with extending limit stoppers; the middle cylinder sleeve is provided with an oil through hole path; the end portions of the internal and the external walls of the middle cylinder sleeve are provided with the oil inlet and the oil outlet holes; the external cylinder sleeve is provided with the oil inlet and the oil outlet holes, and the internal side of the top cover is provided with an oil storage chamber. The utility model has the advantages that telescoping quantity is large, the lower space of a vehicle which is pushed is larger; volume is small; structure is simple, and manufacture is easy.
Description
The utility model belongs to a kind of automatic jack parts, particularly a kind of wall-flow type multi-joint telescoping cylinder.
The jack that uses on automobile at present all is a manual type, and when needing to use, the operator use hand-operated jack, with an angle jack-up of automobile, owing to it only can the jack-up automobile an angle, so the space under the car is little, makes troubles to maintenance.For solving above-mentioned deficiency, the applicant has applied for " jack automatically " (patent No. is 98239297.4) on November 9th, 1 to State Patent Office, uses it, and the driver is sitting in bar handle in the operator's compartment, the automatic jack-up of automobile can have been alleviated driver's labour intensity.But the oil pressure telescoping cylinder stroke of this jack is shorter, makes the space under the automobile limited, still makes troubles to the maintainer.
The purpose of this utility model provides a kind of wall-flow type multi-joint telescoping cylinder, and it is assembled on the automatic jack, can make the automobile lower room of jack-up bigger, is convenient to maintainer's maintenance operation.
The purpose of this utility model is achieved in that it comprises outer cylinder sheath, brings the top cover and the piston of oil outlet into, its technical scheme main points are: cylinder sleeve in the middle of the slidingly assemble in the outer cylinder sheath, slidingly assemble piston in the middle cylinder sleeve, the end of outer cylinder sheath and middle cylinder sleeve is provided with stretches out spacing seam, put at middle cylinder the oil through road is set, and the turnover oilhole is set in the inside and outside wall end of middle cylinder sleeve, and the turnover oilhole is set on outer cylinder sheath, the top cover inboard is an oil cabinet.Its working process is: the oil pump that top cover of the present utility model is passed in and out the turnover oilhole UNICOM jack of oilhole and outer cylinder sheath, when the turnover oilhole of hydraulic oil from top cover enters the oil cabinet, and middle cylinder sleeve and piston one are ejected successively by hydraulic pressure, and the hydraulic oil in the middle cylinder sleeve oil through road is discharged from the turnover oilhole of outer cylinder sheath, and pistons work puts in place; When needs bounced back, hydraulic oil made middle cylinder sleeve and piston push back the position from the oil through road of the middle cylinder sleeve of turnover oilhole injection of outer cylinder sheath by oil pressure, and the hydraulic oil in the oil cabinet is from the turnover oilhole discharge of top cover, end-of-job simultaneously.
The utility model has the advantages that: stroke is big, can make the automobile lower room of jack-up bigger, and volume is little, and is simple in structure, makes easily.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation (retracted state).
Fig. 2 is the utility model extended state scheme drawing.
See Fig. 1,2, concrete structure is as follows: top cover 4 thread connection of bringing oil outlet 3 into are at outer cylinder sheath 7 one ends, the other end of outer cylinder sheath 7 has turnover oilhole 12 and spacing seam 13 is stretched out in setting, the above middle cylinder sleeve 8 of two joints is assembled in the outer cylinder sheath 7, cylinder sleeve 8 two ends all are provided with and stretch out spacing seam 13 in the middle of two joints, many oil through roads 9 are set on the middle cylinder body vertically, and be provided with at two ends, oil through road and lead to the turnover oilhole 6 and 11 of outer wall and inwall, the oil through road of cylinder sleeve communicates in the middle of each thereby make.In order to prevent middle cylinder sleeve 8 and piston 10 retractions excessively, assemble spacing jump ring 1 in middle inboard wall of cylinder liner end.Piston 10 is assembled in the middle cylinder sleeve 8, and constitutes oil cabinet 2 with middle cylinder sleeve end, top cover 4 inside faces.Between top cover 4 and the outer cylinder sheath 8, assembling packing seal 5 between piston 10 and the middle cylinder sleeve 8.
Claims (3)
1, a kind of wall-flow type multi-joint telescoping cylinder, it comprises outer cylinder sheath, brings the top cover and the piston of oil outlet into, it is characterized in that: cylinder sleeve in the middle of the slidingly assemble in the outer cylinder sheath, slidingly assemble piston in the middle cylinder sleeve, the end of outer cylinder sheath and middle cylinder sleeve is provided with stretches out spacing seam, puts at middle cylinder the oil through road is set, and in the inside and outside wall end of middle cylinder sleeve the turnover oilhole is set, the turnover oilhole is set on outer cylinder sheath, and the top cover inboard is an oil cabinet.
