Description
Technical field
Invention relates to a kind of release mechanism, is specifically related to a kind of Manual-automatic integrated formula release mechanism, belongs to mechanical structure technical field.
Background technique
For the mechanism requiring the locking and unlocking at present, in order to improve the reliability of mechanism, normal need to possess automatically realize the locking and unlocking function while, also requirement manually can realize above-mentioned functions.It is large to there is manually-operable power in existing mechanism, cannot realize the problem manually automatically freely switched.But or can realize that above-mentioned functions organization volume is huge cannot install in the confined space.Design the little and reliable in action of volume, the mechanism that manually automatically freely switches become in the urgent need to.
Summary of the invention
In view of this, the invention provides a kind of Manual-automatic integrated formula the locking and unlocking mechanism, mechanism utilizes outside oil pressure or air pressure as power source, two spring bolts in left and right are driven synchronously to stretch out or retract, the function realizing locking or unlock, mechanism can need according to operating mode the switching carrying out hand control and automation operation simultaneously.
A kind of Manual-automatic integrated formula the locking and unlocking mechanism, comprise handle, speed reducer, gear steering device, left spring bolt, right spring bolt and gear rack cylinder, wherein, arrange rack and pinion in gear rack cylinder, tooth bar is moved linearly along cylinder body axis by external drive air pressure in cylinder body, and gear is arranged on above tooth bar, gear rack cylinder is when original state, and gear and tooth bar are in non-engagement state;
Gear steering device inside is provided with three bevel gears, and one of them is driving gear, and all the other two is output gear, and output gear engages with driving gear simultaneously;
On left spring bolt and right spring bolt, processing and the outside thread of nut screw connection, be respectively left-handed and dextrorotation, when gear steering device move, can ensure that latch is stretched out simultaneously and retracts, realize mechanism's unblock and lock synchronous.
Its annexation is: handle is connected with the input end of speed reducer, and the output terminal of speed reducer is fixedly connected with the driving gear in gear steering device, and driving gear is then fixedly connected with the gear in gear rack cylinder by transmission shaft; Two output gears in gear steering device are threaded with left spring bolt and right spring bolt respectively by leading screw, the rotation of leading screw be converted into left spring bolt and right spring bolt along leading screw axis relative to or reverse linear move.
Working principle: wait lock object by left spring bolt and right spring bolt insert wait lock object pin-and-hole in locked, when unlocking employing manual mode, turn handle, speed reducer passes to the driving gear in gear steering device after rotational speed being slowed down, driving gear drives two output gears and screw synchronous to rotate, left spring bolt and right spring bolt relative movement, left spring bolt and right spring bolt depart from from pin-and-hole, realize manual unlocking; Gear now in gear rack cylinder does not engage with tooth bar, and gear dallies, and saves the muscle power of operator; When unlocking employing automated manner, charged pressure oil or the rectilinear movement of high pressure gas drive carry-over bar in the hydraulic fluid port or gas port of gear rack cylinder, tooth bar move after LAP with gears meshing, the rotation of driving gear in the rotation driven gear commutator of gear, and then give two output gears by transmission of power, realize automatic unlocking.
Treat locking object when locking, its locking process and releasing process are completely contrary.
Beneficial effect:
1, gear rack cylinder is used in this mechanism by the present invention, the transform linear motion of tooth bar is the rotation of gear by gear rack cylinder, realize mechanism and unlock and the object of locking after driven gear commutator campaign, manually-operable and automatic operation integrate by the present invention, can freely switch between the two, separate, the reliability that improve mechanism's locking and unlock.
2, the present invention sets up speed reducer between Manual operation handle and gear steering device, can greatly reduce manually-operable power.Additionally by the reduction speed ratio regulating speed reducer, greatly can improve ouput force, resistance when therefore this mechanism can overcome larger unblock and lock.
3, one, nut inner hole screw thread coordinating with left spring bolt and right spring bolt of the present invention is left-handed, and a dextrorotation, when gear steering device moves, can ensure that latch is stretched out simultaneously and retracts, and reliably realizes mechanism and unlocks and locking synchronous.
4, gear rack cylinder of the present invention is when original state, and gear and tooth bar are in non-engagement state, and when manually-operable unlocks or lock, gear rack unlocks the idle running of cylinder internal gear, and tooth bar is static, can reduce manually-operable power.
Accompanying drawing explanation
Fig. 1 is structure of the present invention composition schematic diagram.
Wherein, 1-handle, 2-speed reducer, 3-gear steering device, the left spring bolt of 4-, the right spring bolt of 5-, 6-gear rack cylinder.
Embodiment
To develop simultaneously embodiment below in conjunction with accompanying drawing, describe the present invention.
As shown in Figure 1, the invention provides a kind of Manual-automatic integrated formula the locking and unlocking mechanism, comprise handle 1, speed reducer 2, gear steering device 3, left spring bolt 4, right spring bolt 5 and gear rack cylinder 6, wherein, in gear rack cylinder 6, rack and pinion is set, tooth bar by external pressure or oil pressure actuated, moves linearly along cylinder body axis in cylinder body, and gear is arranged on above tooth bar, gear rack cylinder 6 is when original state, and gear and tooth bar are in non-engagement state;
Gear steering device 3 inside is provided with three bevel gears, and one of them is driving gear, and all the other two is output gear, and output gear engages with driving gear simultaneously;
On left spring bolt 4 and right spring bolt 5, processing and the outside thread of nut screw connection, be respectively left-handed and dextrorotation, when gear steering device 3 moves, can ensure that latch is stretched out simultaneously and retracts, and what realize that mechanism unlocks and lock is synchronous.
