Abstract
The utility model relates to a door bolt structure with an auxiliary locking function. The door bolt structure with the auxiliary locking function comprises a door sheet and a bolt head, wherein the bolt head is connected on the lateral wall of a fixing frame. The door bolt structure with the auxiliary locking function is characterized in that a cavity with an opening in the rear end is arranged in the bolt head, an upper punching hole communicated with the cavity is formed in the upper lateral wall of the bolt head, a strip-shaped hole which is matched with the opening in the rear end of the cavity is formed in the lateral wall of the fixing frame and an auxiliary lock pin capable of moving up and down is arranged in the cavity. A driving mechanism located outside the bolt head drives the auxiliary lock pin to move up and down. Under the unlocking condition, the auxiliary lock pin moves downwards and is totally hidden in the cavity. Under the locking condition, the auxiliary lock pin moves upward and penetrates upward out of the upper punching hole, the auxiliary lock pin can hold part of the inner lateral wall of a bolt hole in a door frame, and therefore an locking area is greatly enlarged. Compared with a common locking method of a safe box that a bolt head is directly inserted into a bolt hole in a door frame or is rotated after being inserted into the bolt hole, the door bolt structure with the auxiliary locking function has the advantages that total locking of the inner lateral wall of the door frame is achieved and anti-theft performance of the safe box is further enhanced.
Description
Technical field
The utility model relates to a kind of bolt that is suitable for strongbox, relates in particular to a kind of door latch structure of energy secondary locking.
Background technology
The bolt structure of existing strongbox comprises and is arranged on the relatively slide plate of horizontal sliding of the door-plate back side, the nose is connected with the door bolt head, the lock construction of the prevention slide plate horizontal sliding on the door-plate, doorframe is provided with and fastens with a bolt or latch a corresponding frame hole, wherein the lock construction kind is a lot, can adopt existing various structure, during locking, in the door bolt hole on the door bolt head insertion doorframe, with lock construction slide plate is locked again, make the door bolt head can not withdraw from frame hole, to reach not by the purpose of others' unlatching, fasten with a bolt or latch and be cylindric as first, the cylindrical hole that door bolt Kong Zewei and a door bolt profile match.And there are some defectives in this security door, if lawless person's sled is not lock, but the frame of forcing open the door, owing to being without any hindering structure between door bolt head and the frame hole, like this as long as the lawless person only need pry open a side of doorframe a little, door bolt head on the slide plate just can be easy to deviate from the shortcoming that exists door-plate easily to be pried open in the door bolt hole of doorframe.The firm degree of being combined with doorframe for improving the door bolt head, the designer improves the latch locking structure of strongbox, generally the sidepiece at the door bolt head is provided with hook portion or similar hook structure, 90-degree rotation intersects the rectangular blocks of bolt and the frame hole across of doorframe after bolt is inserted into frame hole, bolt catches on doorframe, make bolt be difficult for deviating from frame hole, play the pick-proof purpose.
Be the Chinese utility model patent " reverse hooked anti-pry door bolt device " of ZL96229428.4 (notification number is CN2269454Y) such as a patent No., application number is the Chinese invention patent " being used for the door bolt mechanism on the strongbox " of ZL200510060496.2 (publication number is CN1730886Y), be the Chinese utility model patent " a kind of pry-proof bolt structure " of ZL200920118215.8 (notification number is CN201391123Y) such as a patent No., they all disclose the similar pick-proof door bolt structure of pick-proof principle.
There is such common ground in above various pick-proof door bolt structure, and the door bolt head only protrudes the hook portion of a door bolt perisporium or the sidewall screens of protruding axle and frame hole by side, and therefore the door bolt head is less with the position area that frame hole catches on, the anti-insufficient strength of colluding; When locking, need just can play the anti-effect of colluding by the door bolt head around self axis rotation in addition, therefore the drives structure relative complex of bolt, fastening head with a bolt or latch and revolving has a fit structure between the bolt fairlead, could realize that the door bolt head is around its axis rotation purpose.
