Abstract
The utility model discloses a piston rod with an anti-falling structure. The piston rod with the anti-falling structure comprises a rod body, wherein a left annular platform and a right annular platform are distributed in the middle of the rod body separately, an installation platform is arranged at the front end of the rod body, an anti-falling groove is formed between the left end surface of the installation platform and the outer wall of the rod body, a conical boss is arranged on the front end surface of the installation platform, a positioning pillar is arranged on the front end surface of the boss, and a conical positioning groove is formed in the end surface of the positioning pillar. The piston rod with the anti-falling structure is novel in structural design, effectively improves the firmness and stability of a rubber plug after installation due to the design of the structures such as the left annular platform, the right annular platform and the anti-falling groove in the installation platform, avoids the phenomenon of falling, and prolongs the service life.
Description
technical field:
The utility model relates to piston rod processing technique, relates in particular to a kind of piston rod with anti-drop structure.
background technique:
Piston rod is as motion parts comparatively frequently, and piston rod is mainly used in hydropneumatic, engineering machinery, automobile making piston rod, the guide pillar of plastics machinery, the roll shaft of package packing machine, printing machinery, textile manufacturing machine, the axle center that conveying mechanism is used, the linear axis that straight line motion is used.
Sometimes need to be set with rubber stopper for piston rod end and middle part, in long-term frequent motion, often there will be piston obscission, need to carry out detachable maintaining, increased the intensity of work, delayed a large amount of operating times.
model utility content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of piston rod with anti-drop structure, and structural design advantages of simple can effectively reduce the phenomenon that piston rod end and middle part rubber stopper come off, long service life.
The technical solution of the utility model is as follows:
With the piston rod of anti-drop structure, comprise the body of rod, it is characterized in that: the middle part of the described body of rod is provided with left Huan Tai spaced apart, right ring platform, the front end of the body of rod is provided with mounting platform, between the left side of mounting platform and body of rod outer wall, be provided with anticreep low water, the front-end face of mounting platform is provided with the boss of taper, and the front-end face of boss is provided with locating column, and locating column end face is provided with the locating slot of taper.
The described piston rod with anti-drop structure, is characterized in that: described anticreep low water can along on the table top of mounting platform along annular continuous distributed or spaced apart.
The utility model has the advantages that:
The utility model structural design novelty, by the isostructural design of anticreep low water on left Huan Tai, right ring platform, mounting platform, effectively raises soundness and stability after rubber stopper is installed, there will not be obscission, has extended working life.
brief description of the drawings:
Fig. 1 is structural representation of the present utility model.
embodiment:
Referring to accompanying drawing:
With the piston rod of anti-drop structure, comprise the body of rod 1, the middle part of the body of rod 1 is provided with left ring platform 2 spaced apart, right ring platform 3, between left ring platform 2, right ring platform 3, can be set with rubber stopper, difficult drop-off, the front end of the body of rod 1 is provided with mounting platform 4, between the left side of mounting platform 4 and body of rod outer wall, be provided with anticreep low water 5, rubber stopper is arranged on and on mounting platform, is not prone to obscission, the front-end face of mounting platform 4 is provided with the boss 6 of taper, the front-end face of boss 6 is provided with locating column 7, and locating column 7 end faces are provided with the locating slot 8 of taper, and fast and easy positions rubber stopper.
Anticreep low water 5 can along on the table top of mounting platform along annular continuous distributed or spaced apart.
