Abstract
The utility model relates to a whole locking ring type piston which includes a cylinder, the cylinder is installed with a piston and a piston rod, the center of the piston is arranged with a threaded hole and the top end of the piston is arranged with a step, the outer surface of the step is arranged with a locking ring hole and a locking ring groove, a locking ring is fixed and installed in the locking hole and the locking ring groove, the inner end of the piston rod is arranged with a screw and a positioning hole, which connected with the center threaded hole of the piston through the screw. The utility model directly use the thread connection to connect the piston and the piston rod and add a anti-loose locking ring to lock the piston and the piston rod thus to prevent the sudden damage, the utility model has advantages of reasonable design, compact structure, small occupied space, stable and reliable connection.
Description
[technical field]
The utility model relates to a kind of piston structure, especially relates to the whole retainer formula piston that adopts locking retainer to be connected between a kind of piston and the piston rod.
[background technique]
Piston and piston rod are the significant components of liquid gas pressure cylinder, in existing liquid gas pressure cylinder, being connected between piston and the piston rod, take mostly bolt and set screw nut to be set in the inner of piston rod, be provided with attachment hole at the piston centre bit, piston and piston rod are connected together, piston and piston rod are fastenedly connected with set screw nut at piston head then.No matter piston and nut are split or integral body, all there are disadvantage in present piston and these Placements between the piston rod with the chek bolt ways of connecting: its set screw nut is easily loosening, influences the stability of work; Its set screw nut is big, need account for than large space, and the oil cylinder that is not suitable for compact structure uses.
[model utility content]
In order to overcome the above-mentioned shortcoming of prior art, the utility model provides a kind of mode of taking screwed connection between piston and piston rod, it is fixing locking then piston and piston rod integral body to be added again retainer, the whole retainer formula piston of the characteristics that have reasonable in design, compact structure, occupy little space
The technological scheme that its technical problem that solves the utility model adopts is: a kind of whole retainer formula piston, comprise cylinder barrel, piston and piston rod are housed in described cylinder barrel, be provided with screw, be provided with step at this piston center on its top, be provided with retainer hole and gutter in this step periphery, in retainer hole and gutter, retainer is housed, is provided with screw rod and positioning hole, by this screw rod and piston center screw bolt in described piston rod the inner.
Described screw rod positioning hole communicates with retainer hole on the piston tip step periphery.
The beneficial effects of the utility model are: with the Placement that directly adopts screw thread that is connected between piston and the piston rod, and add the locking of locking retainer in integral body, prevent sudden damage, have reasonable in design, compact structure, occupy little space, the advantage of secure and reliable connection.
[description of drawings]
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a retainer structural representation described in the utility model.
Among the figure: 1-cylinder barrel, 2-piston, 3-piston rod, 4-screw, 5-screw rod, 6-retainer hole, 7-gutter, 8-positioning hole, 9-retainer.
[embodiment]
See also Fig. 1 and Fig. 2, a kind of whole retainer formula piston, comprise cylinder barrel 1, piston 2 and piston rod 3 are installed in this cylinder barrel 1, be provided with screw 4 at the center of piston 2, and be provided with step on the top of this piston 2, be provided with retainer hole 6 and gutter 7 in the step periphery, be provided with retainer 9 in this retainer hole 6 and the gutter 7, be provided with screw rod 5 and positioning hole 8 in piston rod 3 the inners, join with piston center screw 4 by this screw rod 5, with the Placement that directly adopts screw thread that is connected between piston 2 and the piston rod 3, integral body adds locking retainer 9 lockings, and its anti-loosing effect is good, has removed set screw nut simultaneously, when saving material, also saved the design space effectively, made the more compact structure of liquid gas pressure cylinder, connected more solid and reliable.
Claims (2)
1, a kind of whole retainer formula piston, comprise cylinder barrel, piston and piston rod are housed in described cylinder barrel, it is characterized in that: be provided with screw, be provided with step on its top at this piston center, be provided with retainer hole and gutter in this step periphery, in retainer hole and gutter, retainer is housed, is provided with screw rod and positioning hole, by this screw rod and piston center screw bolt in described piston rod the inner.
2, whole retainer formula piston as claimed in claim 1 is characterized in that: described screw rod positioning hole communicates with retainer hole on the piston tip step periphery.
