Pipe, slotted nut composition.The sleeve is manipulation instrument；Locating part blocks drive screw；Drive screw passes through positioned at upper sealing
Radial direction circular hole and seal pipe in the middle part of pipe, lower seal pipe are hinged；Locking spring is arranged between locating part and upper seal pipe；Gear
Connected firmly with drive screw；Left lock pin can move back and forth in left guide interior edge axis；Left return spring is located at left lock pin and left guide
Between, left rack connects firmly with left lock pin；Gear and left rack keep engagement；After upper seal pipe and lower seal pipe connect firmly, point
Do not connected firmly with left guide；Right lock pin can move back and forth in right guide interior edge axis；Right return spring positioned at it is right lock and right guide it
Between, right rack connects firmly with right lock pin；Gear also keeps engagement with right rack simultaneously；Upper seal pipe and lower seal pipe connect firmly
Afterwards, connected firmly respectively with right guide；In lower seal pipe bottom, drive screw coordinates that slotted nut is rotatable is fixed on seal pipe
On, it is formed the entirety of sealing in structure.
Lock operation：During released state, with sleeve driven in registry screw rod turret head, inwardly promote axially along a screw spacing
Part, locating part separate with the turret head of drive screw, and sleeve puts drive screw turret head, rotates counterclockwise sleeve, makes driving
Screw rod drives pinion rotation, and gear drives the left rack being engaged with, right rack axially for linear motion to both ends along seal pipe,
Left lock pin connects firmly respectively with left rack, right lock pin and right rack, and left and right sides lock pin stretches out, when lock pin reaches defined position,
To lock in place, remove sleeve, locating part outwards ejects in the presence of locking spring, blocks the turret head of drive screw completely,
Drive screw locking simultaneously keeps locking state, completes lockable mechanism and locks process.
Unblock operation：During locking state, with sleeve driven in registry screw rod turret head, inwardly promote axially along a screw spacing
The turret head of part, locating part and drive screw is kept completely separate, and sleeve puts drive screw turret head, rotates clockwise sleeve, is driven
Dynamic screw rod drives pinion rotation, and gear drives and is engaged with left rack, side is for linear motion axially inwards along seal pipe for right rack,
Left lock pin is connected firmly with left rack, right lock pin and right rack, and arranged on left and right sides lock pin is withdrawn, when lock pin reaches defined position, lock pin
Unblock in place, removes sleeve, locating part outwards ejects in the presence of locking spring, blocks the turret head of drive screw completely
When, drive screw locking simultaneously can keep released state, complete lockable mechanism releasing process.
The utility model has the advantages that：The utility model is compact-sized, easily sealing, and mechanism is simple, easy to operate, locking
After there is return spring to give lock pin axial thrust, lock pin is remained locking state, effectively prevent lock pin because of Mechanism Clearance and
Extraneous vibration accidental unlocking, overall performance are reliable.
