Description
Technical field
The utility model relates to hoisting tool technical field, in particular to a kind of jack piston and baffle ring structures.
Background technique
Jack is a kind of common hoisting tool, and the significant components for influencing its working performance are oil cylinders, and oil cylinder is working
When, workability of stability of the leakproofness and piston and piston rod of piston and cylinder body when moving back and forth for jack
Can all have large effect.Leakproofness is mainly guaranteed that whether secured sealing ring is fixed, with connecing for inboard wall of cylinder block by sealing ring
Whether touching closely determines the height of leakproofness；And the stability of piston and piston rod movement, mainly by piston and piston rod with
The matching degree of inboard wall of cylinder block determines, if fine crack is larger, lacks guide frame, is easy for so that piston when moving back and forth
The case where now left and right deviates, and working performance is caused to be substantially reduced；And sealing ring majority is using sides such as washer cooperation shaft block rings
Formula fixes (such as 6 structure of attached drawing), is easy to loosen after long-time service, influences piston service performance, when I& M
Also relatively complicated, efficiency is relatively low；And washer cooperation shaft block ring has gap apart from oil cylinder, cannot play and lead to piston rod
To.
Utility model content
The purpose of this utility model is to provide for a kind of jack piston and baffle ring structure, and the structure is by leading to work
The setting of plug effectively ensures the leakproofness of piston and oil cylinder inner wall, the stability of piston motion and the working performance of oil cylinder；Together
When also improve the replacement speed of assembly efficiency and sealing ring, be conducive to the assembling and maintenance of oil cylinder.
In order to achieve the above object, the utility model provides following technical solution: a kind of jack piston and baffle ring knot
Structure, including oil cylinder and bottom plate, the outside of the oil cylinder are equipped with housing, and the inside of the oil cylinder is equipped with the piston sheet being slidably connected
Body, the piston rod connecting with piston only, the upper end of the piston rod and oil cylinder inner wall junction, which are equipped with, from top to bottom installs
Elastic spring, first group of baffle ring, upper seal and second group of baffle ring, the side of the piston only, which is equipped with, from top to bottom installs
Guide piston, lower seal, preceding guide piston afterwards.
It is further preferred that the rear guide piston and piston only were integrated.
It is further preferred that the side of the piston only is equipped with annular groove, the preceding guide piston corresponds to ring by inside
The bulge loop of slot is removably connected to piston only.
It is further preferred that the preceding guide piston include semicircular configuration left half before guide piston and the right side half it is leading to
Piston.
It is further preferred that the position that the bottom plate corresponds to oil cylinder is equipped with stair-stepping circular groove.
The utility model has the beneficial effects that setting of the structure by preceding guide piston, allows sealing ring firm
It is fixed, and since the outer diameter of preceding guide piston and the internal diameter of oil cylinder are equal, good guiding role can be played, so that piston
It is not susceptible to left and right offset when moving back and forth with piston rod, effectively ensures the leakproofness of piston and oil cylinder inner wall, improves work
The stability for filling in movement, improves the working performance of oil cylinder；Simultaneously because preceding guide piston is detachably secured to piston only
In the annular groove of side wall, assembly efficiency is improved, improves the replacement speed of sealing ring, is conducive to the assembling and maintenance of oil cylinder.

Specific embodiment
We do further a kind of jack piston described in the utility model and baffle ring structure in conjunction with attached drawing below
Explanation.
As shown in Fig. 1 to Fig. 5, a kind of jack piston and baffle ring structure of the present embodiment, including oil cylinder 1 and bottom plate 2,
The outside of the oil cylinder 1 is equipped with housing 3, and the inside of the oil cylinder 1 is equipped with the piston only 4 being slidably connected, connects with piston only
The piston rod 5 connect, the upper end of the piston rod 5 and oil cylinder inner wall junction are equipped with the elastic spring 11 from top to bottom installed, the
One group of baffle ring 12, upper seal 13 and second group of baffle ring 12, the side of the piston only 4 is equipped with from top to bottom install after lead
To piston 41, lower seal 42, preceding guide piston 43.Guide piston 41 is integrated with piston only 4 after described.The piston
The side of ontology 4 is equipped with annular groove 44, and the preceding guide piston 43 is removably connected to work by the bulge loop 431 that inside corresponds to annular groove
Plug body 4.The preceding guide piston 43 include semicircular configuration left half before guide piston 433 before guide piston 432 and right half.
The position of the corresponding oil cylinder 1 of the bottom plate 2 is equipped with stair-stepping circular groove 21.
The service condition of the cylinder structure is as follows: when rear guide piston 41 and piston only 4 are integrated, piston reciprocating
Stablize when movement it is more preferable, 4 side of piston only be arranged with lower seal 42 then by left half before before guide piston 432 and right half
Guide piston 433 is respectively embedded into fixation on annular groove 44, is limited by the inner wall of oil cylinder 1 with piston only 4 after loading oil cylinder 1 leading
To the left and right displacement of piston 43, the upper and lower displacement of guide piston 43 before being limited by annular groove 44 and the cooperation of bulge loop 431, so that
Preceding guide piston 43 can be very good fixed lower seal 42, simultaneously because 43 outer diameter of preceding guide piston and the internal diameter of oil cylinder 1 connect
Closely, it can be used as good guide frame, influence the reciprocating motion of 4 efficient stable of piston only.And due to preceding guide piston 43
Washable installation, after loss can quick dismounting and change, maintenance efficiency and packaging efficiency are higher.
As an improvement due to rear 41 outer diameter of guide piston close to 1 internal diameter of oil cylinder when, can choose rear guide piston 41
Washable is sheathed on piston only 4, lower seal 42 and preceding guide piston 43 is then successively installed, so that rear guide piston
41, lower seal and preceding guide piston 43 can not be needed related piston only 4 and be replaced together with quick-replaceable upon wear, drop
Low cost.
Wherein, the setting of circular groove 21 is to provide for the installation space of 1 lower end of oil cylinder and preceding guide piston 43.
In the utility model, the upper and lower displacement of guide piston 43 before being limited by annular groove 44 and the cooperation of bulge loop 431, so that
Preceding guide piston 43 can be very good fixed lower seal 42, and can also play the guiding role of piston rod；Through this structure
Production cost is reduced to reduce the installation of component instead of the inner structure using shaft block ring and washer fixed seal ring,
And then assembly efficiency is improved, enhance the service performance of product.
The protection scope of the utility model is not limited to above embodiments and its transformation.Those skilled in that art are with this implementation
The conventional modification and replacement carried out based on the content of example, belongs to the protection category of the utility model.
