Abstract
The utility model provides a hydraulic oil cylinder with a sealing structure which is conveniently disassembled and assembled. The hydraulic oil cylinder comprises a piston rod, a load bearing piston and a cylinder barrel, wherein the piston rod is arranged in the cylinder barrel, the load bearing piston is arranged on a light rod part of the piston rod, and the load bearing piston is connected with the piston rod in a fastening manner; a V-shaped combination sealing ring is arranged between the load bearing piston and the cylinder barrel, and one side of the V-shaped combination sealing ring is also provided with a seal compression ring used for fixing the V-shaped combination sealing ring; and the seal compression ring and the load bearing piston are fixedly connected with a threaded hole of the load bearing piston through screw nails. The hydraulic oil cylinder with the structure which is conveniently disassembled and assembled provided by the utility model has the advantages that the connection of the load bearing piston and the piston rod is fixed and firm, the hydraulic oil cylinder is not easy to loose, the seal compression ring is adopted to fix the V-shaped combination sealing ring, the operation of replacing the V-shaped combination sealing ring of the hydraulic oil cylinder is simple in corrective maintenance, the labor intensity is low, and meanwhile, the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of hydraulic jack of sealing configuration easy to assemble.
Background technique
Existing hydraulic cylinder piston sealing configuration parts with the V-type combined seal ring mainly are the structural types that adopts split, the mounting type of this structure is after being installed in piston on the piston rod first, again the load-bearing piston is threaded connection on piston rod, fix with the V-type combined seal ring that piston will be placed on therebetween, for prevent between load-bearing piston and the piston rod be threaded loosening, with a fastening screw trip bolt it is fixed with piston rod, therefore, when maintenance needs to change the V-type combined seal ring, after Cock screw must being screwed off, again the load-bearing piston is passed through screwing from piston rod, because the weight of load-bearing piston is large, the load-bearing piston of especially large-scale or superhuge hydraulic jack, want the labor intensity that screws off from piston rod very large, therefore working efficiency also has a greatly reduced quality, and prevents that with a fastening screw trip bolt loosening effect neither be very desirable.
The model utility content
The technical problems to be solved in the utility model is: in order to solve existing hydraulic cylinder piston sealing configuration when maintaining, change the V-type combined seal ring inconvenient, and the fixed effect of load-bearing piston is undesirable, a kind of hydraulic jack of sealing configuration easy to assemble is provided, adopt a kind of new structure, solve the problems referred to above.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of hydraulic jack of sealing configuration easy to assemble, comprise piston rod, load-bearing piston and cylinder barrel, described piston rod is installed in the cylinder barrel, described load-bearing piston is installed in the polished rod part of piston rod, load-bearing piston and piston rod are fastenedly connected, between described load-bearing piston and the cylinder barrel V-type combined seal ring is installed, described V-type combined seal ring one side also is equipped with for the fixing seal joint of V-type combined seal ring, described seal joint and load-bearing piston are fixedly connected with tapped hole on the load-bearing piston by screw, one end end face of described load-bearing piston and the end face of piston rod, on described load-bearing piston and the end face that piston rod flushes baffle plate is installed, described baffle plate and piston rod are fixedly connected with tapped hole on the piston rod by screw.
In order to strengthen the sealing between load-bearing piston and the piston rod, between described load-bearing piston and the piston rod O RunddichtringO is installed.
In order to strengthen the sealing between load-bearing piston and the cylinder barrel, between described load-bearing piston and the cylinder barrel combined seal ring is installed.
The beneficial effects of the utility model are, the hydraulic jack of sealing configuration easy to assemble of the present utility model, not only the load-bearing piston be connected with piston rod fastening firm, be difficult for loosening, and adopt seal joint to fix the V-type combined seal ring, hydraulic jack is changed the easy and simple to handle of V-type combined seal ring when maintenance, labor intensity is low, has also improved manufacturing efficiency simultaneously.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of the hydraulic jack of the utility model sealing configuration easy to assemble.
Among the figure: 1, piston rod, 2, the O RunddichtringO, 3, seal joint, 4, the V-type combined seal ring, 5, the load-bearing piston, 6, cylinder barrel, 7, combined seal ring, 8, baffle plate.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1, the utility model provides a kind of hydraulic jack of sealing configuration easy to assemble, comprise piston rod 1, load-bearing piston 5 and cylinder barrel 6, it is characterized in that: piston rod 1 is installed in the cylinder barrel 6, load-bearing piston 5 is installed in the polished rod part of piston rod 1, load-bearing piston 5 is fastenedly connected with piston rod 1, between load-bearing piston 5 and the cylinder barrel 6 V-type combined seal ring 4 is installed, V-type combined seal ring 4 one sides also are equipped with for the fixing seal joint 3 of V-type combined seal ring 4, seal joint 3 and load-bearing piston 5 are fixedly connected with tapped hole on the load-bearing piston 5 by screw, one end end face of load-bearing piston 5 and the end face of piston rod 1, on load-bearing piston 5 and the end face that piston rod 1 flushes baffle plate 8 is installed, baffle plate 8 and piston rod 1 are fixedly connected with tapped hole on the piston rod 1 by screw, between load-bearing piston 5 and the piston rod 1 O RunddichtringO 2 is installed, between load-bearing piston 5 and the cylinder barrel 6 combined seal ring 7 is installed.
The baffle plate 8 that utilization is fixed on piston rod 1 end face blocks load-bearing piston 5, can prevent effectively that it is loosening, use dismountable seal joint 3 that V-type combined seal ring 4 is fixing with it, when maintenance needs to change V-type combined seal ring 4, seal joint 3 with baffle ring and load-bearing piston 5 two ends unloads like a cork, again V-type combined seal ring 4 is changed.After taking this design, obtain the improvement of two aspects: on the one hand, hydraulic jack need be changed the easy and simple to handle of V-type combined seal ring 4 when maintenance, labor intensity is low, also improved simultaneously manufacturing efficiency, on the other hand, the hydraulic jack of this structural type prevent between load-bearing piston 5 and the piston rod 1 be threaded loosening just more safe and reliable.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this model utility technological thought, carry out various change and modification fully.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
