Abstract
The utility model discloses a lifting oil cylinder capable of being fastened. The lifting oil cylinder capable of being fastened comprises a cylinder barrel, a piston rod, a piston and a cylinder bottom. A guide sleeve, a lining and a clamping sleeve are sequentially and tightly listed inside the cylinder barrel. The end portion of the cylinder barrel is connected with a pressing sleeve used for pressing the guide sleeve, the lining and the clamping sleeve. Both the pressing sleeve and the inner hole of the guide sleeve are contacted with the piston rod in a sliding mode. At least three steel balls are evenly distributed on the peripheral directions of the piston. A groove is placed on the clamping sleeve, wherein the steel balls can be clamped in the groove. A sliding sleeve is placed between the lining and the inner hole of the clamping sleeve, wherein the sliding sleeve can be used for fastening the oil cylinder after the steel balls are squeezed into the groove when the piston rod extends out of an end. At the tail end of an oil cylinder and through the function of the sliding sleeve, the steel balls evenly distributed on the peripheral directions of the piston are squeezed into the corresponding groove placed on the clamping sleeve, and therefore fastening effect of the oil cylinder in place can be achieved and the phenomenon that the oil cylinder retracts is avoided.

The model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in the prior art, a kind of elevating ram of locking is provided, produce rebound phenomenon effectively to prevent oil cylinder after putting in place.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of elevating ram of locking, comprise cylinder barrel, piston rod, piston and cylinder bottom, be provided with in the cylinder barrel and be arranged in order the guide sleeve that is adjacent to, lining and cutting ferrule, the cylinder barrel end is connected with and compresses described guide sleeve, the gland of lining and cutting ferrule, the endoporus of gland and guide sleeve all with the piston rod sliding contact, piston circumferentially is evenly equipped with at least three steel balls, offer the groove that can snap in steel ball on the cutting ferrule, be provided with between the endoporus of lining and cutting ferrule and the piston rod to stretch out at piston rod and at the end steel ball clamp-oned in the groove and the flip sleeve of locking cylinder.
Specifically, described steel ball number is six, offers the through hole of placing steel ball on the circumferential wall of piston.
Further, be provided with the guide rod suitable with steel ball number in the described guide sleeve, cover has an end to contact with flip sleeve and promotes flip sleeve steel ball is clamp-oned Compress Spring in the groove on the guide rod.
Be to improve dust-proof effect, described piston rod stretch out the cylinder barrel place be set with can be with the fore and aft motion of piston rod the protective housing of synchronization telescope.
The beneficial effects of the utility model are: the utility model is when oil cylinder stroke is terminal, effect by flip sleeve, with piston circumferentially uniform steel ball clamp-on on the cutting ferrule in the corresponding groove of offering, thereby the oil cylinder that puts in place is produced locking effect, prevented that oil cylinder from producing rebound phenomenon.
