Abstract
The utility model provides a near position that holder of built -in brake spring of doublestage stroke electro hydraulicthruster comprises multiunit couple and two baffles, couple 1 and 2 hooks of each other of couple and respectively the buckle connect and constitute in the buckle groove of overhead gage and baffle down, the spring setting in the restriction frame, one end and the overhead gage elastic connection other end and baffle elastic connection down, the spring restriction put up with the bullet division dimensional limit of brake spring in the biggest withdrawal of messenger's push rod. There has been the spring holder, can have avoided the brake spring bullet to open when installation and dismantlement doublestage stroke electro hydraulicthruster and hurt sb. 's feelings, maintain to make things convenient for safety more.
Description
Art
The utility model relates to a kind of brake spring of bipolar stroke electro hydraulicthruster, especially retrains the retainer of brake spring.
Background technique
At present, known double-stage stroke electro hydraulicthruster is all need at the outside additional brake spring of electro hydraulicthruster, it is complicated that external brake spring makes the cost of electro hydraulicthruster increase external structure, affect attractive in appearance, and there is dismounting difficulty in built-in brake spring, the easy spring that produces flicks the problem of hurting sb.'s feelings suddenly.
Summary of the invention
Outside additional brake spring is used in order to overcome existing double-stage stroke electro hydraulicthruster, hydraulic driver cost is caused to increase external structure complicated, affect attractive in appearance, and there is dismounting difficulty in built-in brake spring, easily producing spring flicks suddenly the deficiency of hurting sb.'s feelings, the utility model provides a kind of retainer of built-in brake spring, this retainer can make the length restriction of the built-in spring of bipolar stroke electro hydraulicthruster within the limits prescribed, the problem of hurting sb.'s feelings can not be flicked, make the disassembly process of hydraulic driver convenient and safe.
The utility model solves the technological scheme that its technical problem adopts: the retainer of the built-in brake spring of double-stage stroke electro hydraulicthruster, be made up of many group hooks and two pieces of baffle plates, hook 1 and hook 2 mutual hooks also respectively buckle be connected in the buckle slot of overhead gage and lower pedal, spring is arranged in limit frame, one end is connected the other end with overhead gage elasticity and is connected with lower pedal elasticity, and brake spring (3) is flicked size restrictions near the position making push rod maximum retraction by spring limit frame.
The beneficial effects of the utility model are, have had spring limit frame, brake spring can be avoided to flick and hurt sb.'s feelings, safeguard convenient safety during installation and removal double-stage stroke electro hydraulicthruster.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structure principle chart of the utility model embodiment 1.
Fig. 2 is the structure principle chart of spring limit frame.
1. push rods, 2. shell, 3. brake spring, 4. retainer, 5. piston, 6. piston bore, 7. base, 8. buckle slot, 9. overhead gage in figure, 10. link up with 1,11. hook 2,12. lower pedals.
Embodiment
