Abstract
The invention discloses a thin-type hydraulic oil cylinder which comprises a cylinder body, and a piston rod and a piston which are arranged in the cylinder body, wherein the port of the cylinder body is provided with a cylinder cover; an oil seal 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; the outer edge of the cylinder cover is provided with a sealing groove; and the sealing piece is embedded in the sealing groove. The cylinder cover is provided with the sealing groove, and the sealing piece is embedded in the sealing groove, so that the sealing operation between the cylinder cover and the cylinder body can be realized, the assembly is more convenient, and the processing cost is lowered.
Description
Technical field
The present invention relates to a kind of hydraulic jack, particularly a kind of slim hydraulic jack.
Background technique
Hydraulic jack is in hydraulic jack, to squeeze into hydraulic oil by power source (manual hydraulic oil pump, electric hydaulic oil pump); The piston rod of hydraulic jack produces straight line motion; Hydraulic jack is an executive component; Be that hydraulic pressure can be converted into mechanical energy, and match, accomplish various mechanical motion with various driving mechanisms.
The hydraulic jack kind is more, and slim hydraulic jack is that volume is less, 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 the piston in the cylinder body, and 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; Need Sealing be embedded in the sealed groove, cylinder cap be installed on the cylinder body again, easy generation Sealing comes off and can't assemble the problem that puts in place in this process; Need be embedded again, influence installation rate; On cylinder body, offer groove on the other hand,, also just increased cost of production if size error occurring will cause whole cylinder body to be scrapped.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: a kind of slim hydraulic jack, and through architecture advances, make installation more convenient, reduce cost.
Technical solution of the present invention 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 said cylinder body port; Be provided with oil seal and guide ring between this cylinder cap and the said piston rod; Be provided with Sealing between said cylinder cap and the cylinder body, said cylinder cap outer rim is provided with sealed groove, and said Sealing is embedded in the said sealed groove.
In the technique scheme, said sealed groove ringwise, said Sealing is the O RunddichtringO that cooperates with this ring packing groove.
Because the utilization of technique scheme; The present invention compared with prior art has advantage: among the present invention the sealed groove between cylinder body and the cylinder cap is opened on the cylinder cap; Sealing is embedded in the sealed groove on the cylinder cap, and one side is installed more convenient, and 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; On cylinder cap, offering groove on the other hand, both had been error to have occurred, and the cost of scrapping cylinder cap is significantly smaller than the cost of cylinder body, had therefore reduced cost of production.
Description of drawings
Below in conjunction with accompanying drawing technological scheme of the present invention is described further:
Accompanying drawing 1 is the background technique structural representation;
Accompanying drawing 2 is the structural representation of the embodiment of the invention one;
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 present invention is described.
Be depicted as a kind of slim hydraulic jack of the present invention like accompanying drawing 2,3; Comprise cylinder body 1; And be arranged at the piston rod 2 and piston 3 in this cylinder body 1, and being provided with cylinder cap 4 at said cylinder body 1 port, this cylinder cap 4 is sheathed on the piston rod 2; Be provided with between cylinder cap 4 and the said piston rod 2 and inwardly be provided with dust ring 5, oil seal 6 and guide ring 7 certainly outward successively; Be provided with Sealing 8 between said cylinder cap 4 outer edge surfaces and cylinder body 1 inboard, said cylinder cap 4 outer rims are provided with sealed groove 9, and said Sealing 8 is embedded in the said sealed groove 9.
As shown in Figure 3, said sealed groove 9 ringwise, said 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.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
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 said cylinder body port; Be provided with oil seal and guide ring between this cylinder cap and the said piston rod; Be provided with Sealing between said cylinder cap and the cylinder body, said cylinder cap outer rim is provided with sealed groove, and said Sealing is embedded in the said sealed groove.
2. slim hydraulic jack according to claim 1 is characterized in that: said sealed groove ringwise, said Sealing is the O RunddichtringO that cooperates with this ring packing groove.
