Abstract
The utility model relates to a single-stage or multi-stage dual-function oil tank fixed-point internal locking mechanism, in particular to a hydraulic cylinder fixed point internal locking mechanism, which belongs to the hydraulic technical field. The utility model is characterized in that a reset spring and a floating piston are installed between the primary cylinder and the secondary cylinder; a locking crank piece is embedded in the neck of the secondary cylinder; a reset spring is arranged at the bottom part of the neck; the primary cylinder and the secondary cylinder are in parallel with the fastening plug screw; the C surface of the fastening plug screw is in parallel with the E surface of the primary cylinder; the shapes of the F and D surfaces of the locking crank piece correspond to the E and C surfaces of the neck of the inclined plane; the fastening plug screw and the primary cylinder are connected through threads. The utility model is characterized by fixed location and small size, and is a fixed-point internal locking mechanism capable of locking up at fixed point in one or more working states.
Description
One, technical field:
The utility model relates to single-stage or multistage two-way cylinder fixed point interlock assembly, particularly relates to oil hydraulic cylinder fixed point interlock assembly, belongs to the hydraulics field.
Two, background technique:
At present, hydraulic locking cylinder mechanism generally is the exterior mechanical lock construction, and volume is bigger, because the designing requirement of single-stage or multistage two-way cylinder, maximum outside diameter is less, and the exterior mechanical lock construction that volume is bigger can not use.
Three, summary of the invention:
The utility model purpose is to provide a kind of structural design of optimizing the location mechanical lock to greatest extent, has fixed position, small volume, the single-stage or the multistage two-way cylinder fixed point interlock assembly that can require less oil hydraulic cylinder to lock to external diameter.
Technical solution:
Between first order cylinder and the second level cylinder Returnning spring, floating piston are housed, lock dog embeds in the draw-in groove of second level cylinder, Returnning spring is equipped with in the draw-in groove bottom, between first order cylinder and the second level cylinder with fastening plug screw, fastening plug screw C face is parallel with first order cylinder E face, lock dog F face is corresponding with inclined-plane draw-in groove E face and C facial contour respectively with the D face, and fastening plug screw first order cylinder is threaded.
Be set with seal ring on the floating piston.
Guide ring is equipped with in first order cylinder and second level cylinder bottom portion.
Fastening screw is provided with seal ring beyond the Great Wall.
The shift motion of floating piston is greater than the distance that embeds the lock dog seam.
When the D face of lock dog contacted with the C face of fastening plug screw, the D face was higher than the C face.
Every grade of cylinder all is provided with draw-in groove.
Every grade of cylinder all is provided with the inclined-plane draw-in groove.
The utility model is because floating piston between first order cylinder and second level cylinder, relies on the floating piston Returnning spring to reset.Lock dog embeds in the inclined-plane draw-in groove at locking state.Satisfy the performance requirement multistage or locking of single-stage two-way cylinder fixed point, and satisfied the requirement of oil hydraulic cylinder maximum outside diameter.This oil hydraulic cylinder fixed point interlock assembly structure is compact and reasonable more, can lock at certain or several working state fixed point, has promptly guaranteed function of use, has little volume again, is provided with the internal mechanical locking framework, reliable lock in single-stage or multistage two-way cylinder.
Four, description of drawings
Fig. 1 is the utility model released state sectional view;
Fig. 2 is the utility model lock state sectional view.
Five, embodiment
The utility model mainly comprises: floating piston 1, first order cylinder 2, fastening plug screw 3, second level cylinder 4, seal ring 5, lock dog 6, lock dog Returnning spring 7, seal ring 8, floating piston Returnning spring 9, guide ring 10, inclined-plane draw-in groove 11, draw-in groove 12 is formed, between first order cylinder 2 and the second level cylinder 4 Returnning spring 9 is housed, floating piston 1, lock dog 6 embeds in the draw-in groove 12 of second level cylinder 4, Returnning spring 7 is equipped with in the draw-in groove bottom, between first order cylinder 2 and the second level cylinder 4 with fastening plug screw 3, fastening plug screw 3C face is parallel with first order cylinder 2E face, lock dog 6F face is corresponding with inclined-plane draw-in groove 11E face and C facial contour respectively with the D face, and fastening plug screw 3 first order cylinders 2 are threaded.
1) releasing process: enter the A mouth of first order cylinder 2 when pressure oil liquid after, slit through lock dog 6 and second level cylinder 4 promotes floating piston 1 to left movement, the design runlength of floating piston 1 is greater than the distance that embeds lock dog 6 seams, floating piston 1 is compression reseting spring 9 in the time of left movement, after Returnning spring 9 compressions put in place, lock dog 6 breaks away from the support of floating piston 1 fully, will shift out inclined-plane draw-in groove 11 at the promotion lower edge of second level cylinder 4 inclined-plane E, while compression reseting spring 7, and move along cylinder barrel with floating piston 1, finish release.
2) locking process: when pressure oil liquid from B to entering oil hydraulic cylinder, promote second level cylinder 4 pistons and move right the top, pressure oil liquid will enter along the slit between guide ring 10 and the first order cylinder 2 in the space of Returnning spring 9 and floating piston 1 simultaneously, floating piston 1 will move right under the effect of pressure oil and Returnning spring 9, lock dog 6 is pushed to inclined-plane draw-in groove 11 belows, when the C face (the D face is higher than the C face) of the D of lock dog 6 face and fastening plug screw when contacting, lock dog 6 will enter inclined-plane draw-in groove 11 along the C face under the effect of Returnning spring 7, when C face and D face, the E face contacts follow-up reforwarding fully with the F face and moves, in being embedded into inclined-plane draw-in groove 11 fully, the piston of floating piston 1 and second level cylinder 4 will continue to move right under the promotion of Returnning spring 9 and pressure oil, up to the terminal position locking oil hydraulic cylinder that moves to first order cylinder 2.After the locking of this oil hydraulic cylinder fixed point interlock assembly, when when the C direction has thrust, lock dog will be stuck by floating piston 1, can't move, so this locking mechanism reliable lock.
