Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a there is not poor cylinder of balanced section fall stage, including cylinder body 1, piston rod 4, sealed section of thick bamboo 2, subassembly 3 and the filler subassembly 8 ventilate, the sealed section of thick bamboo 2 of bolt fixedly connected with is passed through to the side end face of cylinder body 1, inner chamber 6 has been seted up to the inside of cylinder body 1, the subassembly 3 of ventilating with the 6 intercommunication of inner chamber is all installed to the outer terminal surface both sides of cylinder body 1, the inboard slip of inner chamber 6 has inlayed the piston rod 4 that runs through sealed section of thick bamboo 2, 1 formula structure as an organic whole of cylinder body, set up to the same through 6 diameters of two sets of inner chambers with traditional, merge into a set of two sets of inner chambers 6, thereby make into integral type structure with cylinder body 1, the balance section has been cancelled, shorten overall length, reduce material.
