Abstract
The utility model provides a four-column platform lifting machine hydraulic device for automobile maintenance. The four-column platform lifting machine hydraulic device for the automobile maintenance comprises a cylinder barrel and a base fixedly connected to one end of the cylinder barrel, wherein the cylinder barrel and the base are combined to form a cavity allowing a piston rod to be mounted, an oil channel and an oil port which are communicated with the cavity are formed in the base, a top cover is connected to the other end of the cylinder barrel, the piston rod comprises a piston and a rod body connected with the piston, and the rod body penetrates through the top cover stretches out of the cylinder body. The four-column platform lifting machine hydraulic device for the automobile maintenance has the advantages of being stable in operation, free of noise and long in service life.
Description
Technical field
The utility model relates to hydraulic pressure installation technical field, refers to especially the four post platform raising machine hydraulic equipments for auto repair.
Background technique
Along with the increase of China's sale of automobile amount, hydraulic jack is as the important tool of auto repair, and it is bringing into play vital effect in auto repair maintenance.And hydraulic jack is very important parts for hydraulic jack, in whole hydraulic jack, play the part of the role of an executive component, in whole process, hydraulic jack converts mechanical energy to hydraulic energy exactly.But the hydraulic jack that existing hydraulic jack uses moves steadily, occurs even scratching slip surface by noise, cause leakage of oil, reduce working life; Stroke is short, manufacture cost is high, installation is inconvenient.
Model utility content
The utility model proposes the four post platform raising machine hydraulic equipments for auto repair, solved in prior art operation not steadily, have a short problem of noise, working life.
The technical solution of the utility model is achieved in that the four post platform raising machine hydraulic equipments for auto repair, comprise: cylinder barrel, the base being fixedly connected with cylinder barrel one end, described cylinder barrel is combined with base and is formed with the cavity that piston rod is installed, described base is provided with the oil duct and the hydraulic fluid port that are communicated with cavity, the described cylinder barrel the other end is connected with top cover, described piston rod comprises piston and the body of rod being connected with piston, and the described body of rod passes top cover and extends to outside cylinder barrel.
Further preferably, between described piston and described inner wall of cylinder, be provided with seal ring one.
Further preferably, between the described body of rod and described top cover inwall, be provided with seal ring two.
Further preferably, on the described body of rod, be connected with earrings.
Further preferably, on the described body of rod, the one end that connects piston is provided with stop collar.
Further preferably, the joint of the described body of rod and described piston is provided with the back-up ring that prevents that piston from coming off.
The beneficial effect that the utility model possesses is as follows:
Compared with prior art, this hydraulic pressure installation operate steadily, noise free; To slip surface not damaged, long service life; Oil cylinder self stroke is large, and strength is large; Good airproof performance, not easy oil leakage.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
The four post platform raising machine hydraulic equipments for auto repair as described in Figure 1, comprise: cylinder barrel 1, the base 2 being fixedly connected with cylinder barrel 1 one end, described cylinder barrel 1 is formed with base 2 combinations the cavity 3 that piston rod 4 is installed, described base 2 is provided with the oil duct 5 and the hydraulic fluid port 6 that are communicated with cavity 3, described cylinder barrel 1 the other end is connected with top cover 7, described piston rod 4 comprises piston 41 and the body of rod 42 being connected with piston 41, and the described body of rod 42 passes top cover 7 and extends to outside cylinder barrel 1.
Welded a base 2 in one end of a cylinder barrel 1, hydraulic fluid port 6 is opened on base 2 with oil duct 5, and is connected with the cavity 3 in cylinder barrel 1.Piston rod 4 is placed in cavity 3, with cavity 3 interference fit.Piston rod 4 comprises piston 41 and the body of rod 42, and piston 41 is fixedly connected with the body of rod 42, and a back-up ring 10 is also installed in joint, prevents that piston 41 from coming off.For guarantee piston rod 4 cavity 3 interior reciprocating in, do not allow piston 41 collide top cover 7, it is come off, on the body of rod 42, near one end of piston 41 stop collar 9 being installed.On top cover 7, have a through hole, the body of rod 42 passes and extends to the outside of cylinder barrel 1 from through hole, be also fixedly connected with earrings 8.
In order to guarantee the sealing of oil cylinder, be difficult for leakage of oil occurs, between piston 41 and cylinder barrel 1 inwall and between the body of rod 42 and top cover 7 inwalls, be respectively arranged with seal ring 1 and seal ring 2 11.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
