Abstract
The utility model discloses a double-lock mechanism for a coffer door. Fragile objects are arranged at a lock tool and a plurality of places which are near to the lock tool. The fragile objects suspend a heavy object by a soft rope. If the lock tool and the vicinity of the lock tool encounter with destruction and invasion, the fragile objects are broken, or the soft rope is cut; the heavy object which is suspended on the soft rope decreases under the action of gravitation, and clamps the clamping moving mechanism of an existing lock bolt so that the door is heavily locked. Thus when a coffer encounters with destruction, the utility model realizes that the coffer door can not be provided with the emergency actions of the device.
Description
The utility model relates to a kind of lockset, more specifically to the heavy latch mechanism of a kind of national treasury door.
Under durable, the survivable situation of national treasury door integral body, saboteur's direction of attack mainly is lockset, rotating disk linkage and installation position on every side thereof.The method that adopts is modes such as striking, prize, bore, cut.Present tamper-proof technology mainly is to strengthen the anti-damage ability of lockset itself and reinforce installation lockset peripheral part.If the saboteur has destroyed lockset or peripheral part is destroyed in the lump, Ku Men still can call together to unnormal unlocking.How to prolong the unnormal unlocking time, become antitheft key.
The purpose of this utility model is to provide a kind of urgent heavy locking device, and when being implemented in lockset and seating part thereof and going to pot, Ku Men still can not be prolonged the time to rupture of unnormal unlocking by unnormal unlocking.
For realizing above-mentioned purpose of the present utility model, concrete technical scheme is: the heavy latch mechanism of a kind of national treasury door, comprise lockset (2), switch wheel (5), door lock bolt clamping plate (9) and locking bolt (10), switch wheel (5) and connecting rod (13), (16) constitute crank-link mechanism, can spur door lock bolt clamping plate (9) and locking bolt (10) bounces back to the centre along guide peg (15), it is characterized in that described lockset (2) and switch wheel (5) are neighbouring, the inboard of national treasury door is provided with easily mince (6), and connect heavy lock dog (4) by lifting rope (3).
The utility model since lockset and near some place be provided with easily and mince, easily mince and hang a weight by a tightrope, once lockset and near suffer destroy to invade, easily fragment fragmentation or tightrope disconnect, the weight that hangs on the tightrope descends gravitate, block original lock and fasten clamping movement mechanism, with Men Chongsuo.Go to pot when taking place thereby be implemented in national treasury, this device emergency action still can't be opened Ku Men.
Enumerate most preferred embodiment of the present utility model below in conjunction with accompanying drawing.
Fig. 1 is the utility model structure principle chart.
Fig. 2 be among Fig. 1 A to view.
Fig. 3 be among Fig. 1 B to view.
The normal duty of national treasury door lock is, open coded lock (2), dead bolt on it (14) withdraws from the groove on the switch wheel (5), rotating switch wheel (5), the dead bolt (14) of lockset this moment (2) and switch wheel (5) and connecting rod (13), (16) constitute crank-link mechanism, to the centre retraction, door is normally opened along guide peg (15) for pulling door lock bolt clamping plate (9) and locking bolt (10).Fig. 1 and Fig. 2 show, lockset (2) and switch wheel (5) near, the inboard of national treasury door body (1) is provided with easily mince (6), and connects weight lock dog (4) by lifting rope (3).In the time of near stealer destruction lockset (2), switch wheel (5) reach, easily mince (6) at first must be smashed, Fig. 3 shows that heavy lock dog (4) descends, because the existence of the groove (19) on the heavy lock dog (4) just rides on the guide rail (17), occupy between the two track roller framves (18) sky every, make the locking bolt clamping plate (9) and the locking bolt (10) on both sides to bounce back, door still can not be opened.
Claims (3)
1. a national treasury door weighs latch mechanism, comprise lockset (2), switch wheel (5), door lock bolt clamping plate (9) and locking bolt (10), switch wheel (5) and connecting rod (13), (16) constitute crank-link mechanism, can spur door lock bolt clamping plate (9) and locking bolt (10) and bounce back to the centre, it is characterized in that described lockset (2) and switch wheel (5) are neighbouring, the inboard of national treasury door is provided with easily mince (6), and connect heavy lock dog (4) by lifting rope (3) along guide peg (15).
2. the heavy latch mechanism of national treasury door according to claim 1 is characterized in that described heavy lock dog (4) does steady directed movement by guide rail (17) restriction.
3. the heavy latch mechanism of national treasury door according to claim 1 and 2 is characterized in that described heavy lock dog (4) has groove (19)
