Abstract
The utility model relates to a new linkage type multiple lock bolt metallic theft-proof door. Interlocked transverse linkage rods are arranged on a lock tongue of a theft-proof door lock; the linkage rods can be connected with a set or a plurality of sets of longitudinal linkage rods arranged on a door leaf through hinges; the longitudinal linkage rods can directly be connected with one end of a longitudinal lock bolt arranged in the door leaf through the hinges; the other end of the lock bolt is matched with a lock bolt hole on a door frame. The adopted theft-proof door has the advantages of good theft-proof performance, simple structure, convenient operation, good breakage-proof performance, etc. The shortage of the prior art can be overcome; the utility model is an ideal metallic theft-proof door having good theft-proof performance.
Description
The utility model relates to a kind of metal anti-theft door of building, specifically refers to a kind of novel many locking bolts of linkage type metal anti-theft door.
Metal anti-theft door is the very general building anti-theft device of a kind of use.Existing metal anti-theft door mainly is made up of metal door frame and metal door leaf, its main anti-theft measure then mainly adopts comparatively firm metal door body and has the theftproof lock of certain theftproof performance, this security door can play antitheft preferably effect to a certain extent, but the theftproof lock that existing metal anti-theft door adopted is often destroyed easily, because existing metal anti-theft door all is to adopt single lock point, adopt various tools used in crime by force theftproof lock destruction or direct door leaf to be pried open as the robber, existing in this case security door often is difficult to play real antitheft purpose.In addition, existing metal anti-theft door also exists use comparatively complexity, the more high deficiency of inconvenient operation cost of manufacture in operation.
The purpose of this utility model is to provide a kind of novel many locking bolts of linkage type metal anti-theft door, many bolt structures and the very shirtsleeve operation structure that are adopted to pass through by the control of theftproof lock dead bolt interlock, make it in function of use that keeps prior art preferably and theftproof performance, also have advantages such as good, simple in structure, the easy to operate and preventing destructing performance of theftproof performance is good, overcome the deficiencies in the prior art preferably.
The purpose of this utility model realizes in the following manner: a kind of novel many locking bolts of linkage type metal anti-theft door, consist predominantly of metal door frame, metal door leaf and safe-guard door lock, wherein the safe-guard door lock device is on door leaf, it is characterized in that the dead bolt of safe-guard door lock is provided with the transverse brace of interlock, this link rod is connected with one or more groups flange bracing on being arranged on door leaf by hinge, above-mentioned flange bracing directly by hinge be arranged on door leaf in vertically an end of locking bolt link to each other, the other end of this locking bolt matches with the locking bolt hole on the doorframe, and above-mentioned dead bolt moves laterally by the lock driving lever with the lock core interlock.
Adopt many locking bolts of linkage type metal anti-theft door of the present utility model, owing to adopted many bolt structures and very shirtsleeve operation structure by the control of theftproof lock dead bolt interlock, make it in function of use that keeps prior art preferably and theftproof performance, also have advantages such as good, simple in structure, the easy to operate and preventing destructing performance of theftproof performance is good, having overcome the deficiencies in the prior art preferably, is a kind of comparatively desirable, novel metal security door with good theftproof performance.
Description of drawings:
Accompanying drawing is a kind of example structure schematic diagram of the present utility model.
Wherein: the 1-door leaf, the 2-doorframe, the 3-safe-guard door lock, the 4-dead bolt, 5-locks driving lever, 6-lock core, 7-transverse brace, 8-hinge, 9-flange bracing, 10-locking bolt, 11-locking bolt hole.
Below in conjunction with drawings and Examples the utility model is further described.
As shown in the figure, a kind of novel many locking bolts of linkage type metal anti-theft door of the present utility model, consist predominantly of metal door frame 2, metal door leaf 1 and safe-guard door lock 3, wherein safe-guard door lock 3 devices are on door leaf 1, it is characterized in that the dead bolt 4 of safe-guard door lock 3 is provided with the transverse brace 7 of interlock, this link rod is connected with one or more groups flange bracing 9 on being arranged on door leaf 1 by hinge 8, above-mentioned flange bracing 9 directly links to each other with a end of vertical locking bolt 10 in being arranged on door leaf 1 by hinge, the other end of this locking bolt 10 matches with the locking bolt hole 11 on the doorframe 2, and above-mentioned dead bolt 4 moves laterally by the lock driving lever 5 with lock core 6 interlocks.
The middle part of above-mentioned flange bracing 9 and two ends are provided with hinge 8, the hinge at middle part is connected with transverse brace 7, the hinge at two ends directly links to each other with an end of locking bolt 10, this flange bracing 9 when locking-in state and locking bolt 10 form certain angles, be stuck to prevent locking bolt.
Above-mentioned locking bolt 10 can adopt one or more groups interlock that locking bolt is all arranged up and down, also can adopt one or more groups only to have the interlock of locking bolt or following locking bolt, has locking bolt hole 11 corresponding to locking bolt head place on doorframe.
When implementing, above-mentioned locking bolt is arranged in the door leaf, in the longitudinal metal pipe of door leaf or the metal sheet interlayer of door leaf (totally-enclosed door leaf), one end of its transverse brace directly is fixed on the dead bolt tail end of safe-guard door lock, the other end links to each other with flange bracing by hinge, when the user opens safe-guard door lock by key, lock driving lever on the lock core is stirred dead bolt, promoting flange bracing by transverse brace moves backward, driving locking bolt moves downward and leaves locking bolt hole on the doorframe, reach the purpose of opening the door, reverse operating is then finished the action of locking a door.
Above-mentioned security door has been owing to adopted many locking bolts theft-prevention structure, thereby its theftproof performance and preventing destructing performance be greatly improved, and realized the purpose of this utility model effectively.
