Slow down latch bolt and the impulsive force of doorframe prior to Forced rotation after latch bolt and door frame contact, realize Jing Yin in one end of power-assisted piece protrusion
Close the door；Latch bolt is provided with platform, and power-assisted piece is provided with groove, and the bottom surface of groove is engaged with the platform of latch bolt, and door lock has assembled
Cheng Hou, the platform of latch bolt are located at outside lock body, and power-assisted piece one end is against on lock body, after door lock is locked, in latch bolt insertion doorframe, now
The gap of door and doorframe is inserted with card etc., card is located in the platform and groove of latch bolt, and firmly latch bolt can not be stirred to card
It is collapsible into lock body, i.e., can not opening door lock.
In a kind of latch bolt structure of described safe-guard door lock, described power-assisted piece is U-shaped, and power-assisted piece is provided with hole, helps
Power piece is by hole together with latch bolt hinge connection.
In a kind of latch bolt structure of described safe-guard door lock, in the U-shaped both ends of described power-assisted piece, the one of latch bolt is stretched out
End is slightly below the other end, and the other end of power-assisted piece is against on lock body, and power-assisted piece is collapsible into lock body as fulcrum.
In a kind of latch bolt structure of described safe-guard door lock, described latch bolt includes two latch bolt pieces, latch bolt piece propylaeum
Outer side is provided with platform, space is left between two latch bolt pieces, power-assisted piece is located in the space of two latch bolt pieces and hinge connects
Connect.
In a kind of latch bolt structure of described safe-guard door lock, the bottom surface of described power-assisted piece upper groove for plane and with it is oblique
The platform of tongue piece is located at approximately the same plane.
Power-assisted piece in the utility model is provided with groove structure, after the completion of lockset assembling, when with card etc. insert door with
During the gap of doorframe, card is located in the groove of power-assisted piece, and because gap is narrow and small, the card of insertion can only vertically be used along card direction
Power, now card can not stir power-assisted piece, can not make latch bolt retraction lock body in, i.e., can not abnormal start-up door lock, solve existing
Latch bolt because card stirs latch bolt curved surface cause illegal opening door lock the problem of, improve the theftproof performance of lockset.
The utility model has the characteristics of Anti-inserting piece is opened, security is higher compared with existing lockset latch bolt structure.
