Abstract
The utility model relates to an ejector rod of a charging valve. The ejector rod comprises a rod body, an upper limiting connection sleeve and a lower limiting fixation sleeve. The ejector rod of the charging valve has the innovative points in that: an upper clamp spring groove and a lower clamp spring groove are respectively at the upper part and the lower part of a rod body; an upper clamp spring and a lower clamp spring are respectively nested in the upper clamp spring groove and the lower clamp spring groove; the upper limiting connection sleeve is mounted on the upper clamp spring through a stopping screw; and the lower limiting fixation sleeve is sleeved on the lower clamp spring by pressing. The upper limiting connection sleeve and the lower limiting fixation sleeve are fixedly arranged on the rod body through the clamp springs. Compared with a ring clamping groove, the sizes of the upper clamp spring groove and the lower clamp spring groove are greatly reduced, so that the breaking of the rod body of the ejector rod is avoided, and the service life is prolonged.
Description
Technical field
The utility model relates to a kind of liquid-filling valve, particularly a kind of liquid-filling valve push rod of not easy-rupturing.
Background technique
Liquid-filling valve is a kind of Pilot operated check valve, a direction fluid stopping, and another direction free flow has reliable sealing performance, in metal forming machinery, is widely used.
The push rod of liquid-filling valve is provided with a upper limit and a lower limit, and upper limit is used for fixing the Returnning spring on the push rod, and lower limit is used for fixing the spool of liquid-filling valve.Traditional liquid-filling valve push rod structure is as shown in Figure 1, and the upper limit of push rod 1 adopts upper limit connecting sleeve 7 to be threaded in push rod top, and upper limit connecting sleeve 7 sidewalls are established the fastening screw 8 that props up push rod 1; Lower limit adopts push rod 1 bottom to open annular groove, and the embedded semicircle snap ring 9 of annular groove is provided with fixed cover 10 and locking cap 11 respectively at the upper and lower of snap ring 9, is fixed on snap ring 9 places by fixed cover 10 and locking cap 11 screw-thread fit.The shortcoming of this kind structure is: the size of annular groove is relatively large, makes the push rod easy-rupturing at this place, and influence is used normally, safeguards very inconvenient; The connecting sleeve of upper limit is threaded with push rod, processing, inconvenient installation.
Summary of the invention
The technical problem that the utility model will solve provides a kind of liquid-filling valve push rod of not easy-rupturing.
For solving the problems of the technologies described above; The technological scheme of the utility model is: a kind of liquid-filling valve push rod; Comprise the body of rod, upper limit connecting sleeve and lower limit fixed cover; Its innovative point is: said body of rod upper and lower is opened jump ring groove and lower circlip groove respectively, and said going up in jump ring groove and the lower circlip groove is embedded with jump ring and lower circlip respectively; Said upper limit connecting sleeve is installed on the jump ring through the fastening screw, and said lower limit fixed cover is installed on the lower circlip through crimping.
The advantage of the utility model is: upper limit connecting sleeve and lower limit fixed cover all are fixed on the body of rod through jump ring, and the size of upper and lower jump ring groove is compared annular groove and reduced greatly, have avoided the fracture of the push rod body of rod, have improved working life.
Description of drawings
Fig. 1 is for adopting the liquid-filling valve structural representation of traditional push rod structure.
Fig. 2 is a liquid-filling valve push rod structure schematic representation in the utility model.
Fig. 3 is installed in structural representation on the liquid-filling valve push rod for upper limit connecting sleeve in the utility model and lower limit fixed cover.
Embodiment
Like Fig. 2, shown in 3, comprise the body of rod 1, last jump ring groove 2, lower circlip groove 3, go up jump ring 4, lower circlip 5, lower limit fixed cover 6, upper limit connecting sleeve 7 and fastening screw 8.
The upper and lower of the above-mentioned body of rod 1 has jump ring groove 2 and lower circlip groove 3, in last jump ring groove 2 and lower circlip groove 3, is embedded with jump ring 4 and lower circlip 5 respectively.
After lower limit fixed cover 6 is installed on the lower circlip 5 through frock, through being fixed on the lower circlip 5 after the upper end extruding closing in of crimping with lower limit fixed cover 6.Upper limit connecting sleeve 7 is fixed on the jump ring 4 through fastening screw 8 after being installed on the jump ring 4.
Claims (1)
1. a liquid-filling valve push rod comprises the body of rod, upper limit connecting sleeve and lower limit fixed cover, it is characterized in that: said body of rod upper and lower is opened jump ring groove and lower circlip groove respectively, and said going up in jump ring groove and the lower circlip groove is embedded with jump ring and lower circlip respectively; Said upper limit connecting sleeve is installed on the jump ring through the fastening screw, and said lower limit fixed cover is installed on the lower circlip through crimping.
