Abstract
The utility model discloses a thin type hydraulic oil cylinder. The thin type hydraulic oil cylinder comprises a cylinder body, a piston rod and a piston, wherein the piston rod and the piston are arranged in the cylinder body, a cylinder cover is arranged at a port of the cylinder body, an oil sealing piece and a guide ring are arranged between the cylinder cover and the piston rod, a sealing piece is arranged between the cylinder cover and the cylinder body, a sealing groove is arranged at the outer edge of the cylinder cover, and the sealing piece is embedded in the sealing groove. By arranging the sealing groove on the cylinder cover and embedding the sealing piece in the sealing groove, sealing operation between the cylinder cover and the cylinder body is realized, so that assembling of the thin type hydraulic oil cylinder is more convenient, and processing cost is reduced.
Description
Technical field
The utility model relates to a kind of hydraulic jack, particularly a kind of slim hydraulic jack.
Background technique
Hydraulic jack is to squeeze into hydraulic oil by power source (manual hydraulic oil pump, electric hydraulic oil pump) in hydraulic jack, the piston rod of hydraulic jack produces straight line motion, hydraulic jack is executive component, to be mechanical energy with hydraulic energy transfer, and match with various driving mechanisms, finish various mechanical motion.
The hydraulic jack kind is more, slim hydraulic jack is small volume, a kind of oil cylinder that installing space is economized, be applicable to mould, the restricted mechanical occasion of processing jig or installing space, its basic structure is: comprise cylinder body, and be arranged at piston rod and piston in the cylinder body, be provided with cylinder cap at the cylinder body port, be provided with Sealing and guide ring between cylinder cap and the piston rod, as shown in Figure 1, be provided with seal ring 103 between cylinder cap 101 outer edge surfaces and cylinder body 102 inner edge surfaces, seal ring 103 is arranged in the groove that is opened on cylinder body 102 inner edge surfaces, to realize the sealing between cylinder cap 101 and the cylinder body 102.
Yet because sealed groove is opened on the cylinder body inner edge surface, one side is when assembling, Sealing need to be embedded in the sealed groove, cylinder cap be installed on the cylinder body again, easily the generation Sealing comes off and can't assemble the problem that puts in place in this process, need to again be embedded, affect installation rate; Offer groove at cylinder body on the other hand, will cause whole cylinder body to be scrapped if size error occurs, also just increased cost of production.
Summary of the invention
For the technical problem of above-mentioned existence, the purpose of this utility model is: a kind of slim hydraulic jack, and by architecture advances, make installation more convenient, reduce cost.
Technical solution of the present utility model is achieved in that a kind of slim hydraulic jack, comprise cylinder body, and be arranged at piston rod and piston in this cylinder body, be provided with cylinder cap at described cylinder body port, be provided with oil seal and guide ring between this cylinder cap and the described piston rod, be provided with Sealing between described cylinder cap and the cylinder body, described cylinder cap outer rim is provided with sealed groove, and described Sealing is embedded in the described sealed groove.
In the technique scheme, described sealed groove ringwise, described Sealing is the O RunddichtringO that cooperates with this ring packing groove.
Because the utilization of technique scheme, the utility model compared with prior art has following advantages: in the utility model the sealed groove between the cylinder block and cylinder cover is opened on the cylinder cap, Sealing is embedded in the sealed groove on the cylinder cap, install on the one hand more convenient, Sealing is embedded in the sealed groove on the cylinder cap, cylinder cap is installed on the cylinder body, Sealing comes off when avoiding assembling again; Offering groove at cylinder cap on the other hand, both has been error to have occurred, and the cost of scrapping cylinder cap is significantly smaller than the cost of cylinder body, has therefore reduced cost of production.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is the background technique structural representation;
Accompanying drawing 2 is the utility model embodiment one structural representation;
The structure for amplifying schematic representation of cylinder cap among accompanying drawing 3 Fig. 2.
Wherein: 1, cylinder body; 2, piston rod; 3, piston; 4, cylinder cap; 5, dust ring; 6, oil seal; 7, guide ring; 8, Sealing; 9, sealed groove; 101, cylinder cap; 102, cylinder body; 103, seal ring.
Embodiment
Below in conjunction with accompanying drawing the utility model is described.
Be depicted as a kind of slim hydraulic jack described in the utility model such as accompanying drawing 2,3, comprise cylinder body 1, and be arranged at piston rod 2 and piston 3 in this cylinder body 1, be provided with cylinder cap 4 at described cylinder body 1 port, this cylinder cap 4 is sheathed on the piston rod 2, be provided with between cylinder cap 4 and the described piston rod 2 from being provided with successively outside to inside dust ring 5, oil seal 6 and guide ring 7, be provided with Sealing 8 between described cylinder cap 4 outer edge surfaces and cylinder body 1 inboard, described cylinder cap 4 outer rims are provided with sealed groove 9, and described Sealing 8 is embedded in the described sealed groove 9.
As shown in Figure 3, described sealed groove 9 ringwise, described Sealing 8 is the O RunddichtringO that cooperates with this ring packing groove 9.When assembling, the O RunddichtringO is sheathed in the ring packing groove 9, then cylinder cap 4 is installed (usually to be threaded) with cylinder body 1.
Above-described embodiment only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage that is familiar with technique can understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in the protection domain of the present utility model.
Claims (2)
1. slim hydraulic jack, comprise cylinder body, and be arranged at piston rod and piston in this cylinder body, be provided with cylinder cap at described cylinder body port, be provided with oil seal and guide ring between this cylinder cap and the described piston rod, be provided with Sealing between described cylinder cap and the cylinder body, described cylinder cap outer rim is provided with sealed groove, and described Sealing is embedded in the described sealed groove.
2. slim hydraulic jack according to claim 1 is characterized in that: described sealed groove ringwise, described Sealing is the O RunddichtringO that cooperates with this ring packing groove.
