Abstract
The utility model relates to a combined unlocking device for a national treasury door, composed of three locks arranged on the national treasury door, two connecting rods connected with adjacent lock arms, pull rods hinged with the connecting rods, pull arms hinged with the pull rods, a right-angle-shaped support rod connected with the pull arms and a stop arranged on a movable door plug. When the two locks in the three locks are opened, the right-angle-shaped support rod can disengage from the stop and the movable door plug can move to open national treasury door. Therefore, the simultaneous operation of two people when the national treasury door is opened, an eyewitness is provided. Only two locks of the three locks are needed to be opened, and the phenomenon that the national treasury door can not be opened because one person forgets passwords or one lock malfunctions is avoided. The utility model is widely suitable for various national treasury doors and important anti-theft doors.
Description
The utility model relates to a kind of national treasury apparatus for door-opening, the compound opening device of especially a kind of national treasury door.
Existing national treasury door, one of operated by rotary motion or two locks, this structure has a shortcoming, as long as a handle lock out fault or one of them people forgets operator password, the national treasury door just can not be opened, and has influenced operate as normal, just open and to destroy the national treasury door, the national treasury door is scrapped, needed to repair again, cause damage.
The purpose of this utility model is to provide a kind of national treasury door compound opening device, and three locks promptly are set on the national treasury door, appoints and to open wherein the compound opening device that two locks just can be opened the national treasury door.
The utility model is to realize above-mentioned purpose like this: the compound opening device of national treasury door, by the link stopper that is welded on national treasury every bolt, the right angle type push rod that is installed on the top arm that withstands link stopper having on the national treasury door with hinges is formed, it is characterized in that the torque arm that the useful hinges in the end of another straight flange of right angle type push rod connects, one end of the other end of torque arm and pull bar is hinged versatilely, the other end of pull bar is movably arranged on the connecting rod with hinge respectively, the two ends of connecting rod connect with the hammerlock of two adjacent locks is movable respectively, the two ends of connecting rod two connect the hammerlock of adjacent lock is movable with other respectively, adorn the end of two connecting rods on the hammerlock of that lock of centre in three locks.Hammerlock drivening rod, pull bar, torque arm move right when opening a lock, the right angle type push rod is rotated around the hinge fulcrum at place, right angle, and the top arm on the right angle type push rod moves up, but still withstands link stopper, when opening another lock, top arm moves up again, exceeds link stopper, so just the mobile keeper of energy, open the national treasury door, certainly this structure just can be with this structural change for after opening three locks fully as long as adjust the height that the right angle type push rod withstands link stopper, the device that the national treasury door could be opened.
Because the utility model adopts three locks to appoint to be driven two locks and just can open the national treasury door, make that opening the national treasury door will have two people's operations simultaneously, and eye-witness is provided, and three only need open two to coded lock and avoided wherein a people to forget that password or can not open the defective of national treasury door locking out existing fault.
Below in conjunction with accompanying drawing the utility model is done concrete detailed description the in detail.
Fig. 1 is a schematic diagram of the present utility model;
Fig. 2 is concrete structure figure of the present utility model.
With reference to Fig. 1, when opening lock A, A lock hammerlock retreats to E ' point by the E point, connecting rod E～F walks around hinge F and rotates, driving pull bar H-J moves right, when moving right, pull bar H-J the right angle type push rod is rotated around the O point by torque arm J-K, the top arm O-M that the right angle type push rod withstands link stopper D moves up, this moment, top arm O-M did not also break away from link stopper D, and then open lock C, C lock hammerlock retreats to G ' point by the G point, and connecting rod F～G rotates around hinge F, drives pull bar I-G and moves right, when moving right, pull bar I-G the right angle type push rod is rotated around the O point by torque arm J-K, the top arm O-M that the right angle type push rod withstands link stopper D moves up again, and this moment, top arm O-M broke away from link stopper D, and the national treasury door just can be opened.
With reference to Fig. 2, with 10,12, adjacent two locks 10 in 13 3 locks, 12 and 12,13 hammerlock links up with connecting rod 9 and 11 respectively, i.e. two connecting rods 9 and 11 outer end and the lock 10 of outermost end, 13 hammerlock connects, two connecting rods 9 and 11 all connect with the hammerlock of centre lock 12 by intermediate ends, on every connecting rod 9 and 11, a pull bar 7 is housed between the hammerlock tie point, 8, pull bar 7,8 the other end is linked together, connect with hinge is movable with an end of torque arm 5 again, the other end of torque arm 5 connects with a straight flange of right angle type jacking block 4 is movable, the place, right angle of right angle type jacking block 4 is connected together the right angle type jacking block 4 and the national treasury couplet on the door with hinge 6, another straight flange of right angle type jacking block 4 is that the end of top arm 14 is in order to withstand the link stopper 2 that is welded on the keeper 1, the top of top arm 14 and link stopper 2 is equipped with a mobile shift fork 3, and its lower end propped up top arm 14 when mobile shift fork 3 was vertical.
With reference to Fig. 2, rotating shift fork 3 makes it parallel and do not withstand top arm 14, open lock 10, the hammerlock of lock 10 moves right, connecting rod 9 is rotated around hinge F, drive pull bar 7 and move right, make right angle type push rod 4 around 0 rotation by torque arm 5 when pull bar 7 moves right, the top arm 14 that the right angle type push rod withstands link stopper 2 moves up, and top arm 14 did not also break away from link stopper 2 and still withstood link stopper 2 this moment; And then open lock 13, the hammerlock of lock 13 moves right, connecting rod 8 rotates around hinge F, driving pull bar 7 moves right, when moving right, pull bar 7 top arm 14 on the right angle type push rod 4 is moved up by torque arm 5, top arm 14 breaks away from link stoppers 2 at this moment, and national treasury every bolt 1 just can move right, thereby opens the national treasury door.
In like manner, open lock 10 and 12 or lock 12 and 13, equally can open the national treasury door; When adjusting the position that top arm 14 withstands link stopper 2, perhaps increase or reduce the height of link stopper 2, can with three locks all or only a lock just open and can open the national treasury door.
