Abstract
The utility model discloses a floor spring earth's axis piston structure, its including the host computer cylinder body, set up the piston in the host computer cylinder body, the spiro union has tail stopper bolt in the host computer cylinder body one end, the shaping has the hydraulic pressure oilhole on the piston, the shaping of piston periphery has annular ka tai, the cover is equipped with the circle with annular card platform matched with nylon cushion in the piston periphery, nylon cushion circles and puts the shaping of corresponding department with the hydraulic oil hole site and have the opening, the both ends shaping of nylon cushion circle has outer fringe and parcel to be in the piston both ends. The utility model discloses an establish the circle with piston structure matched with nylon cushion at piston periphery cover, do not influence piston structural strength, utilize the expend with heat and contract with cold performance of nylon cushion circle, make piston and host computer cylinder body fit clearance increase when temperature goes up and down and reduce to eliminate hydraulic oil because temperature descends, mobile variation is to the influence of product function, and it is level and smooth to make the piston remove, difficult wearing and tearing and warping.
Description
Technical field:
This utility model relates to floor spring manufacturing technology field, particularly to a kind of floor spring earth's axis piston structure.
Background technology:
During floor spring life-time service commercially, owing to temperature lifting makes piston and cylinder holes fit clearance strengthen and reduce, and piston is by the uneven pressure of spring, piston is easily deformed and weares and teares, so that the service life of floor spring reduces, it is also possible to during use send sharp-pointed noise.
Utility model content:
This utility model provides floor spring earth's axis piston structure, solves the problem that piston in prior art is easily deformed and weares and teares.
Technology solution of the present utility model is as follows: a kind of floor spring earth's axis piston structure, it includes cylinder body of host machine, the piston being arranged in cylinder body of host machine, tail plug bolt it is bolted with in described cylinder body of host machine one end, hydraulic pressure oilhole is formed on described piston, described piston outer periphery forms annular chuck, the nylon washer matched with annular chuck it is arranged with on described piston outer periphery, form opening on described nylon washer with corresponding section, hydraulic oil hole site, described nylon washer two ends form outer rim and are wrapped in described piston two ends.
At the sheathed nylon washer matched with piston structure of piston outer periphery, do not affect piston and move and structural strength.
As preferably, on described piston with tail plug bolt away from one end be connected and have spring.Piston is promoted to move by spring.
As preferably, the cross section of described nylon washer is convex shape.Nylon washer structure matches with piston, does not affect piston structure intensity.
As preferably, thickness size is piston diameter size 0.05 times ~ 0.15 times of described nylon washer.
As preferably, described nylon washer lateral surface reclines mutually with cylinder body of host machine medial surface.
The beneficial effects of the utility model are: by the sheathed nylon washer matched with piston structure of piston outer periphery, do not affect piston structure intensity, utilize the performance of expanding with heat and contract with cold of nylon washer, piston and cylinder body of host machine fit clearance is made to strengthen when temperature lifts and reduce, thus eliminate hydraulic oil due to mercury dropped, the impact on product function of the mobility variation, make piston gliding smoothing, the most easy to wear and deformation.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
In figure: 1, cylinder body of host machine；2, piston；3, tail plug bolt；4, hydraulic pressure oilhole；5, nylon washer.
Detailed description of the invention:
In conjunction with accompanying drawing 1 to this utility model floor spring earth's axis piston structure, it is described further.
A kind of floor spring earth's axis piston structure of the present utility model, its piston 2 including cylinder body of host machine 1, being arranged in cylinder body of host machine 1, tail plug bolt 3 it is bolted with in cylinder body of host machine 1 one end, hydraulic pressure oilhole 4 is formed on piston 2, piston 2 periphery forms annular chuck, being arranged with the nylon washer 5 matched with annular chuck on piston 2 periphery, nylon washer 5 forms with corresponding section, hydraulic pressure oilhole 4 position opening, nylon washer 5 two ends form outer rim and are wrapped in piston 2 two ends.
Further, on piston 2 with tail plug bolt 3 away from one end be connected and have spring.
Further, the cross section of nylon washer 5 is convex shape.
Further, thickness size is piston diameter size 0.1 times of nylon washer 5.
Further, nylon washer 5 lateral surface reclines mutually with cylinder body of host machine 1 medial surface.
Operation principle of the present utility model is: the sheathed nylon washer 5 matched with piston 2 structure in piston 2 periphery, utilize the performance of expanding with heat and contract with cold of nylon washer 5, piston 2 and cylinder body of host machine 1 fit clearance is made to strengthen when temperature lifts and reduce, thus eliminate hydraulic oil due to mercury dropped, the impact on product function of the mobility variation, make piston 2 gliding smoothing, the most easy to wear and deformation.
The foregoing is only preferred embodiment of the present utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, all should belong to the scope of this utility model protection.
