When original state, nine of the combination lock 125 and the lock strap key 115 are located on the foremost side four in combining
Group needs that the lock strap key 115 is pushed just to be able to rotate, remaining five groups are unlocking shape between the lock strap key 115 being inserted into
State.
When needing replacing password lock position, the most four lock strap keys 115 in front side are inserted into finger, the lock strap
115 lower end of key drives the tooth of engagement to turn chamber 116 and rotate in an anti-clockwise direction, with the tooth turn chamber 116 it is coaxial it is fixed it is described after
End wheel 128 rotates in an anti-clockwise direction, and drives the fixture block 130 to move, the fixture block 130 is due to by the slot inner slide 131
Supporting role, slided while first can be using the contact point of the fixture block 130 and the slot inner slide 131 as centre swinging to the left
It is dynamic, until contact point between the two is located at 127 top of fastening groove, in the work of the torque spring at 130 rear of fixture block
Under, the fixture block 130 is entirely fallen into the fastening groove 127, and the lock strap key 115 moves to the leftmost side at this time, although
Active force of the lock strap key 115 by fixed and 125 right side of combination lock spring to the right, but due to the slot
Inner slide 131 sticks the fixture block 130, and causing the tooth to turn chamber 116 can not rotate, therefore 115 position of lock strap key is protected
The left end in movement is held, at this point, the lock strap key 115 will push to the left the phase support rod 113, keeps the external screw thread sliding
Bar 107 slides to the left, rotates the female threaded shaft 123, makes to consolidate the rotation fixture block that block 101 offsets with the hook tooth
105 are rotated up, and stop the state that offsets, and the motor 103 works, and the solid switch block 118 is driven to rotate, the password adjustment chamber
120 are sequentially located at the lower section of the lock caulking groove 124, fall into the combination of the combination lock 125 and the lock strap key 115 described
Password adjusts in chamber 120, and then the combination of the combination lock 125 and the lock strap key 115 is sorted by password requirement,
It reinstalls the rear motor 103 to work, is transferred to the release link 119 in the rotation chamber 137, presses down on the reset
Bar 119 rotates clockwise the rotating block 134 and the butt end piston 138 is pushed to move right, makes in the hydraulic slot 126
Liquid-driving described in piston with rod 133 move right, push the slot inner slide 131 to slide in the sliding groove 132, make
The fixture block 130 can be rotated out completely in the fastening groove 127, then pushed away by spring fixed on the lock strap key 115
It moves the lock strap key 115 and returns to original position.
When needing to open the door, the door band phase support block 110 is inserted into finger and is caught in the door body 100 and the combination lock
The lock strap key 115 in the lock strap key 115,125 combination lock of combination lock between 125, the lock strap key 115 will
The lock strap phase support block 109 pushes away upwards in turn, when four groups of locks are all inserted into and finish, holds the rotation hand lever 121 and rotates
Several angles make an opening, then the release link 119 is pressed in the original place restored after opening, keep the lock strap key 115 multiple
Original arrives in situ.
The beneficial effects of the present invention are: when original state, during nine of the combination lock and the lock strap key combine, position
Four groups in most front side need that the lock strap key is pushed just to be able to rotate, remaining five groups are being inserted between the lock strap key as
Unlocking condition.
When needing replacing password lock position, the most lock strap key of front side four is inserted into finger, the lock strap key
Spoon lower end drives the tooth of engagement to turn chamber and rotates in an anti-clockwise direction, and turns the coaxial fixed rear end wheel of chamber side counterclockwise with the tooth
To rotation, the fixture block is driven to move, the fixture block, first can be with the card due to the supporting role by the slot inner slide
The contact point of block and the slot inner slide is slided to the left while being centre swinging, until contact point between the two is positioned at described
Above fastening groove, under the action of the torque spring at the fixture block rear, the fixture block is entirely fallen into the fastening groove, at this time
The lock strap key moves to the leftmost side, although the lock strap key by the fixed spring with the combination lock right side to the right
Active force, but since the slot inner slide sticks the fixture block, causing the tooth to turn chamber can not be rotated, therefore the lock strap
Key position is maintained at the left end of movement, at this point, the lock strap key will push to the left the phase support rod, makes the outer spiral shell
Line slide bar slides to the left, rotates the female threaded shaft, makes to consolidate the rotation fixture block that block offsets with the hook tooth and turns upwards
It is dynamic, stop the state that offsets, the motor work drives the solid switch block rotation, and the password adjusts chamber and is sequentially located at the lock
The lower section of caulking groove falls into the combination of the combination lock and the lock strap key in the password adjustment chamber, then by the institute
The combination for stating combination lock and the lock strap key is sorted by password requirement, is reinstalled the rear motor work, is made the reset
It is intracavitary that bar is transferred to the rotation, presses down on the release link, rotates clockwise the rotating block and push the butt end piston
It moves right, moves right piston with rod described in the liquid-driving in the hydraulic slot, push the slot inner slide described
It is slided in sliding groove, rotates out the fixture block completely in the fastening groove, it is then fixed on the key by the lock strap
Spring pushes the lock strap key to return to original position.
When needing to open the door, the institute that the door is caught in phase support block between the door body and the combination lock is inserted into finger
State lock strap key, the lock strap key in combination lock combination lock, the lock strap key by the lock strap phase support block upwards in turn
It pushes away, when four groups of locks are all inserted into and finish, holds the rotation hand lever and rotate several angles, make an opening, restored after opening
Original place, then press the release link, the lock strap key made to recover to original position.
The configuration of the present invention is simple, it is easy to operate, by the way that multiple keys are installed in multiple keyholes, only by it is right just
True key key could open convenience and safety that door effectively increases equipment.
Those skilled in the art can define, can in the case of not departing from overall spirit of the invention and design
