Chamber 15 facilitates to push inner piston 11 mobile and drives piston rod 5 mobile, and when inner piston 11 is mobile, because inner piston 11 with
Interior air cavity 15 is sealing state, therefore when inner piston 11 is mobile, will push the air pressure of its front end, by the air pressure of its front end by holding
The entrance of chamber 9 is set, to push brake piston 19, facilitates and is extracted in the embedding hole by brake bar 18 by 5 two sides of piston rod, convenient for work
Stopper rod 5 is unlocked, conversely, can mitigate the air pressure in accommodating cavity 9, to when can move to utilize spring in inner piston 11
20 will be such that brake piston 19 back moves by push plate, so that brake bar 18 is driven to be embedded in the embedding hole on 5 surface of piston rod again,
Convenient for being lockked to piston rod 5, and there are two the total settings of brake bar 18, the two sides of piston rod 5 are respectively corresponded, may be implemented
Double self-locking functions.
The working principle of the invention is: firstly, when inner piston 11 in cylinder works, air pressure enters the by air inlet 10
In two outer air cavitys 16, while the gas in the second outer air cavity 16 is pushed to be passed through interior air cavity by connecting hole 13 using the first outer piston 12
It,, can be by air pressure one of its front end when inner piston 11 moves forward convenient for pushing inner piston 11 to move forward using air pressure in 15
Divide and entered by accommodating cavity 9, so that brake piston 19 be pushed to move down, and then drives brake bar 18 by the embedding of 5 two sides of piston rod
It is extracted in hole, convenient for being unlocked to piston rod 5, conversely, in inner piston 11 to when can move, it can be by the air pressure in accommodating cavity 9
Mitigate, to brake piston 19 will be made back to move by push plate using spring 20, so that brake bar 18 be driven to be embedded in work again
In the embedding hole on 5 surface of stopper rod, convenient for lockking to piston rod 5, and there are two the total settings of brake bar 18, piston is respectively corresponded
The two sides of bar 5, may be implemented the function of double self locking, also, when inner piston 11 moves forward, 11 front end of inner piston it is another
Partial gas pressure is entered in the first outer air cavity 14 by pressure hole 143, and pushes the second outer piston 142 mobile, convenient for passing through outside second
Piston 142 pushes the air pressure in the first outer air cavity 14, and then is jacked up gag lever post 144 by top plug 141, convenient to inner piston 11
Limit self is carried out, while being to prevent inner piston 11 being moved through to limit to gag lever post 144 using limit plate 172
The ejection of gag lever post 144 in journey positioned at 11 front end of inner piston facilitates gag lever post 144 can be in inner piston 11 to influence its movement
It can be ejected upwards when forward movement by air pressure promotion, and by the limit of limit plate 172, gag lever post 144 can be made to eject
Sequence is that the rearward position for being located at inner piston 11 by one end of limit plate 172 successively ejects, when inner piston 11 is shunk, limit
The retraction sequence of bar 144 is then opposite；
And the air pressure in accommodating cavity 9 and the first outer air cavity 14 is mutually complementary with the air pressure of 11 front end of inner piston, and its internal gas
It presses constant, when inner piston 11 moves forward, the air pressure of 11 front end of inner piston can be promoted accommodating cavity 9 and the first outer air cavity 14
It is interior, so that brake piston 19 just moved down to the embedding hole for making brake bar 18 extract 5 surface of piston rod, and by gag lever post
144 release upwards, so that latching limit is carried out to inner piston 11, when inner piston 11 bounces back, accommodating cavity 9 and the first outer air cavity 14
Internal air pressure can bounce back, and then drive brake bar 18 to move up, and be embedded in the embedding hole on 5 surface of piston rod, while making to limit
Position bar 144 bounces back downwards, releases the limitation locking to inner piston 11, and make using the cooperation of brake bar 18 and gag lever post 144
With double self-locking functions to cylinder may be implemented, further improve the use quality of cylinder.
