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 that requires at present the locking and unlocking, in order to improve the reliability of mechanism, often need to possess when automatically realizing the locking and unlocking function, also requirement can manually realize above-mentioned functions.Existing mechanism exists manually-operable power large, cannot realize the problem of manually automatically freely switching.Or can realize that but above-mentioned functions mechanism is bulky cannot install in the confined space.Design the little and reliable in action of volume, manually the mechanism of automatically freely switching 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, drive two spring bolts in left and right synchronously stretch out or retract, realize the function of locking or release, mechanism can need to carry out according to operating mode the switching of hand control and automation operation simultaneously.
One 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, in gear rack cylinder, rack and pinion is set, tooth bar is moved linearly along cylinder body axis by external drive air pressure in cylinder body, and gear is arranged on tooth bar top, 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, the outside thread that coordinates with nut of processing, is respectively left-handed and dextrorotation, when gear steering device moves, can guarantee that latch stretches out simultaneously and retract, realize mechanism's release and locking synchronously.
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 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 by leading screw respectively, 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: object to be locked is inserted by left spring bolt and right spring bolt in the pin-and-hole of object to be locked its locking, when release adopts manual mode, turn handle, speed reducer passes to the driving gear in gear steering device after rotational speed is slowed down, driving gear drives two output gears and screw synchronous rotation, left spring bolt and right spring bolt relatively move, and left spring bolt and right spring bolt depart from from pin-and-hole, realize manual unlocking; Now the gear in gear rack cylinder does not engage with tooth bar, gear idle running, saving operator's muscle power; When release adopts automated manner, to charged pressure oil or the rectilinear movement of high pressure gas drive carry-over bar in the hydraulic fluid port of gear rack cylinder or gas port, tooth bar engages with gear after moving LAP, 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 while locking, its locking process is completely contrary with releasing process.
Beneficial effect:
1, the present invention is used in gear rack cylinder in this mechanism, gear rack cylinder is converted into the straight line motion of tooth bar the rotation of gear, thereby after driven gear commutator campaign, realize the object of mechanism's release and locking, the present invention integrates manually-operable and automatic operation, can freely switch between the two, separate, improved the reliability of mechanism's locking and release.
2, the present invention sets up speed reducer between Manual operation handle and gear steering device, can greatly reduce manually-operable power.By regulating the reduction speed ratio of speed reducer, can greatly improve ouput force in addition, resistance when therefore this mechanism can overcome larger release and locking.
3, one, the nut inner hole screw thread that the present invention coordinates with left spring bolt and right spring bolt is left-handed, and a dextrorotation, when gear steering device moves, can guarantee that latch stretches out simultaneously and retract, and reliably realizes the synchronous of mechanism's release and locking.
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 release or locking, gear rack release cylinder internal gear dallies, and tooth bar is static, can reduce manually-operable power.
Accompanying drawing explanation
Fig. 1 is structure composition schematic diagram of the present invention.
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
Below in conjunction with the accompanying drawing embodiment that develops simultaneously, 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, the interior rack and pinion that arranges of gear rack cylinder 6, tooth bar by external pressure or oil pressure actuated, moves linearly along cylinder body axis in cylinder body, and gear is arranged on tooth bar top, gear rack cylinder 6 is when original state, and gear and tooth bar are in non-engagement state;
