Compared with the prior art, the utility model, designed the angle stroke actuating mechanism that has buffer function, increased the spring case air inlet on the spring case for the preliminary compression power of spring compression sets up the piston cylinder gas outlet bottom the piston cylinder, and increased extension structure on piston one, through the exhaust of extension structure control piston cylinder, thereby slow down the velocity of motion of piston one, reach the effect of the sealed face of protection valve and valve shaft.
Description
Technical Field
The utility model belongs to the technical field of the mechanical skill and specifically relates to an angle stroke actuating mechanism with buffer function.
Background
During the use process of the pneumatic spring return angular travel actuating mechanism, the shaft is often twisted and deformed due to the rapid movement of the spring in the return process, and the sealing surface is deformed due to high-speed impact.
Therefore, it is desirable to design an angular stroke actuator with a buffering function, which can prevent the deformation of the valve sealing surface and the valve shaft during the spring return process.
Disclosure of Invention
The utility model aims at overcoming the not enough of prior art, provide an angle stroke actuating mechanism with buffer function, can avoid the valve seal face and valve shaft to warp at the spring reset in-process.
In order to achieve the above object, the utility model relates to an angle stroke actuating mechanism with buffer function, including piston cylinder, crank, spring cartridge, its characterized in that: the bottom of the piston cylinder is provided with a cylinder cover, the bottom of a cylinder body of the piston cylinder is provided with a piston cylinder air outlet, a first piston is arranged in the piston cylinder, the bottom of the first piston is provided with an extension structure, the top of the first piston is connected with one end of a crank, the other end of the crank is connected with a second piston of a spring cylinder, and a spring cylinder air inlet is formed in the wall of the spring cylinder.
The extension structure shields the air outlet of the piston cylinder or is separated from the air outlet of the piston cylinder.
The end part of the spring cylinder is provided with a spring.
Compared with the prior art, the utility model, designed the angle stroke actuating mechanism that has buffer function, increased the spring case air inlet on the spring case for the preliminary compression power of spring compression sets up the piston cylinder gas outlet bottom the piston cylinder, and increased extension structure on piston one, through the exhaust of extension structure control piston cylinder, thereby slow down the velocity of motion of piston one, reach the effect of the sealed face of protection valve and valve shaft.
Drawings
Fig. 1 is a structural diagram of the present invention.
Detailed Description
The invention will now be further described with reference to the accompanying drawings.
Referring to fig. 1, the utility model relates to an angle stroke actuating mechanism with buffer function, including the piston cylinder, the crank, the spring cylinder, the bottom of piston cylinder 1 is equipped with cylinder cap 11, and the cylinder body bottom of piston cylinder 1 is provided with piston cylinder gas outlet 12, is equipped with piston 13 in the piston cylinder 1, and the bottom of piston 13 is equipped with extending structure 14, and the top of piston 13 is connected with crank 2's one end, and crank 2's the other end is connected with piston two of spring cylinder 3, is equipped with spring cylinder air inlet 31 on the section of thick bamboo wall of spring cylinder 3, and the tip of spring cylinder 3 is equipped with spring 32.
The utility model discloses be connected through crank 2 between piston one 13 of piston cylinder 1 and the piston two of spring case 3 to through 2 output torque in crank.
The utility model discloses increase spring case air inlet 31 on 3 section of thick bamboo walls of spring case for the preliminary compression power of spring actuating mechanism spring compression. The bottom of the piston cylinder 1 is provided with a piston cylinder air outlet 12, an extension structure 14 is additionally arranged on the first piston 13, and the extension structure 14 shields the piston cylinder air outlet 12 or is separated from the piston cylinder air outlet 12.
The utility model discloses at the during operation, 12 air losses of piston cylinder gas outlet and spring cartridge air inlet 31, and spring 32 restores to the throne and kick-backs, and two promotion crank 2 of piston through spring cartridge 3 drive the first 13 motion of piston cylinder 1, the gas in the compression piston cylinder 1. At this moment, extension structure 14 and the separation of piston cylinder gas outlet 12, the gas of compressed is discharged from piston cylinder gas outlet 12, when piston 13 moves to being close 1 bottom of piston cylinder, extension structure 14 shelters from piston cylinder gas outlet 12, the area of giving vent to anger is reduced, give vent to anger to piston cylinder 1 and hold back, exhaust velocity slows down this moment, pressure reduction speed slows down in the piston cylinder 1 to one 13 slow down the rate of motion of piston, reach the purpose of the sealed face of protection valve and valve shaft, reset completely until spring 32.
