Embodiment Construction

[0021] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] like figure 2 The embodiment shown is a two-way double-acting oil cylinder, which includes two cylinder barrels 3 whose bottom ends are butted, a cylinder head 1 arranged at the top of the cylinder barrel 3, and a piston 2 arranged in the cylinder barrel 3. The two cylinders 3 are connected, and the inner wall of the bottom end is provided with a limit card key 4, and each corner of the limit card key 4 is rounded; a circlip 5 is arranged on the top of the limit card key 4, In the case of a total length of 230mm, the telescopic strokes S of the pistons at both ends are each 50mm.

[0023] like image 3 In the shown embodiment, the limit snap key 4 is in the shape of an annular or partially annular protrusion, which has an inclined surface in contact with the piston 2, and the inclined angle of the inclined surf...

Abstract

A bidirectional double-acting oil cylinder comprises two cylinder barrels butted at the bottom ends, cylinder covers arranged at the top ends of the cylinder barrels, as well as pistons arranged in the cylinder barrels, wherein the two cylinder barrels are communicated, the inner wall of the bottom end of each cylinder barrel is provided with a spacing clamp key; and each edge angle of each spacing clamp key is a fillet. The axial dimension and the use cost of the oil cylinder are reduced.

Description

technical field [0001] The invention relates to an oil cylinder, in particular to a two-way double-acting oil cylinder. Background technique [0002] In some applications, two oil cylinders are required to complete the piston extension or retraction action back to back at the same time. The force required for extension or retraction can be different, and the action sequence of the two cylinders can also be different, but the axial size of the cylinder is required. As small as possible, such as in the application of the patent: a load-bearing mechanism and its load-bearing track, patent No. 200810103251.7, the axial dimension directly affects the size and use cost of the 80-meter load-bearing track of the patent. A conventional oil cylinder is composed of a cylinder, a piston, a cylinder bottom, a cylinder head, seals, supports, and connectors. Circumstances are indispensable, if attached figure 1 As shown, but the setting of the cylinder bottom increases the axial dimensio...
