Problems solved by technology
[0007] The purpose of the present invention is to provide a hydraulic cylinder gland with a sealing structure to solve the problem of poor sealing effect of the sealing ring inside the hydraulic cylinder gland on the market as proposed by the above-mentioned background technology, and when the sealing ring is damaged, impurities are easily released It is brought into the inside of the hydraulic cylinder, causing the hydraulic oil inside the hydraulic cylinder to be polluted, and the right side of the guide rod inside the existing hydraulic cylinder is not very convenient when disassembling and installing the replacement punch, resulting in stamping of simple parts. When molding, it brings inconvenience to people

The invention discloses a hydraulic oil cylinder gland with a sealing structure. a first clamping slot, a gland body is arranged inside the cylinder body, a threaded joint is fixed above the connecting block, a connecting rod is installed on the inner side of the connecting block, a second airbag is fixed on the upper right side of the first ventilation pipe, and A second ventilation pipe is connected to the lower right side of the second air bag, a guide rod is arranged on the inner side of the gland body, and the upper and lower sides of the right end of the guide rod are engaged with positioning rods. The hydraulic oil cylinder gland with a sealing structure is installed with a third air bag, and when the third air bag expands, it can be effectively clamped and fixed with the second slot on the inner side of the filter screen, thereby avoiding the long-term use of the first air bag. After the damage occurs in the hydraulic cylinder, the oil inside the hydraulic cylinder is polluted, which increases the practicability.
Description
technical field [0001] The invention relates to the technical field of hydraulic oil cylinder glands, in particular to a hydraulic oil cylinder gland with a sealing structure. Background technique [0002] The hydraulic cylinder is a mechanism that can realize a variety of mechanical functions. Common functions include clamping, punching and positioning, etc. There are two oil holes on the upper and outer sides of the hydraulic cylinder, through which the hydraulic oil can be pumped into the hydraulic cylinder. inside the hydraulic cylinder, so that the guide rod inside the hydraulic cylinder can effectively play a telescopic role. In addition, there is a gland on the right side of the hydraulic cylinder. The main function of the gland is to avoid oil leakage when the hydraulic cylinder is working. In turn, the hydraulic cylinder brings a lot of convenience to people; [0003] However, the glands of hydraulic cylinders on the market still have defects, such as: [0004] 1....
