Abstract
The utility model relates to a theftproof door with a latch locking mechanism. A main lock bolt on a door body and a latch of an auxiliary lock are extended into a door frame from the side face of the door body. The latch locking mechanism is arranged in the door frame and is composed of a contacting plate and a locking rod, and a transmission mechanism is used for connecting the contacting plate and the locking rod. The inner side of a main lock hole is provided with the contacting plate which corresponds to the position of the main lock bolt, one end of the locking rod is connected with the transmission mechanism, and the other end of the locking rod corresponds to the position of a groove on the latch. When the locking is carried out, the main lock bolt is extended into the main lock hole, and simultaneously, the contacting plate is pushed, the locking rod is driven to extend into the groove of the latch by the transmission mechanism, and then the latch of the auxiliary lock is locked. A resetting part of the locking rod is arranged, which is convenient for opening. The utility model has the advantages of strong total resistance of failure, good safety performance, simple structure, easy manufacture, and easy operation.
Description
The utility model relates to a kind of security door, is the improvement to existing two-bolt lock locking mechanism security door.
Two of existing security door operated by rotary motion are independently locked each other.Wherein one being main lock, is arranged on the Men Tiyi side relative with hinge, and when locking a door, dead bolt can extend out to the doorframe from the door body; Another is for dividing lock, and its pull bar pulling latches that lean on extend in the doorframe from the door body side surface more.The security door of this structure is when going to pot, owing to divide several latches of lock to stretch in doorframe, the difficulty of in advance destroying main lock is bigger, so divide lock to go to pot earlier often, latch is deviate from from doorframe, and then destroys main lock.Through using proof, though its safety of the security door of this structure is better than the monolock security door, overall survivability still relatively a little less than.
The utility model purpose is to obey above-mentioned shortcoming of the prior art and a kind of security door with latch lockable mechanism is provided, and improves the anti-damage performance of security door.
The utility model purpose can be achieved through the following technical solutions:
Security door with latch lockable mechanism comprises doorframe, door body in the composition, the two is connected by hinge.The Men Tiyi side relative with hinge is provided with main lock, has main lockhole on the doorframe relative with main latch bolt position.The door body is provided with the branch lock, divides the latch of lock to extend in the doorframe from the door body side surface.Key improvements part of the present utility model is to set up the latch lockable mechanism in doorframe, comprises touch panel and locking rod in the composition of this lockable mechanism, and the two is connected by transmission mechanism.Touch panel is located at the main lockhole inboard on the doorframe, and is relative with main latch bolt position, and an end of locking rod links to each other with transmission mechanism, and the other end is relative with the groove location on the latch.During the security door locking, the main dead bolt of door on the body stretches in the main lockhole in the doorframe, promotes touch panel simultaneously, and touch panel drives locking rod with its suffered thrust by transmission mechanism and moves, and makes it to stretch in the groove of latch, thereby will divide the latch locking of lock.For realizing the unlatching of latch lockable mechanism smoothly, be provided with the locking rod reset components.
Above-mentioned security door with latch lockable mechanism comprises axle, central siphon and rotating disk during described transmission mechanism is formed.Axle is fixed in the doorframe inboard, and central siphon is sleeved on the axle, and the two is complementary.Fixedly connected between the inwall of rotating disk and the outer wall of central siphon, an end of locking rod is fixedly connected on the outer wall of rotating disk.
Above-mentioned security door with latch lockable mechanism, described locking rod reset components is made up of the support plate that is located at the stage clip on the locking rod and match.
Above-mentioned security door with latch lockable mechanism, described doorframe inboard is provided with the locking rod locating support.
Set two locks of the utility model were both independent each other, organically combined as a whole by the latch lockable mechanism again.Behind the locking, even divide lock destroyed, its latch also will not be deviate from from doorframe, so overall survivability is strong, security performance is good, and is simple in structure, making and easy to use.
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the A-A generalized section of Fig. 1.
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment:
Doorframe 1 of the present utility model is connected by hinge with 2 of bodies of door, and the Men Tiyi side relative with hinge is provided with main lock 3, has main lockhole 5 on the doorframe relative with main dead bolt 4 positions.The middle part of door body is provided with the branch lock, divides the latch 6 of lock to be spurred by known drag link mechanism, divides the latch 6 of lock to extend in the doorframe 1 from door body 2 sides.Be provided with the latch lockable mechanism in the doorframe, comprise touch panel 7, locking rod 8 and the transmission mechanism of forming by axle 9, central siphon 10, rotating disk 11 in the composition of this lockable mechanism.Touch panel 7 is located at main lockhole 5 inboards on the doorframe 1, and an end is fixedlyed connected with central siphon, and the other end is relative with main dead bolt 4 positions, and axle 9 is fixed in doorframe 1 inboard, and central siphon 10 is sleeved on the axle 9, and the two can relatively rotate.Rotating disk 11 is shaped as thin hollow cylinder, fixedlys connected between the outer wall of its inwall and central siphon 10, and an end of locking rod 8 is fixedly connected on the outer wall of rotating disk 11, and the other end is relative with groove 12 positions on the latch 6.Be to realize smoothly the unlatching of latch lockable mechanism, on locking rod 8, be provided with stage clip 13 and locking rod reset components that the support plate 14 that matches is formed.
Be provided with locating support 15 in the doorframe inboard with locking rod 8 position opposite positions, accurately insert in the grooves 12 to guarantee locking rod 8.
When security door needs locking, will divide the lock locking earlier, promptly latch 6 stretches in the doorframe 1 from door body 2, again locking master lock.When main dead bolt 4 stretches in the main lockhole in the doorframe locking, promote touch panel 7, touch panel drives central siphon 10 and is fixed on rotating disk 11 rotation on the central siphon under the effect of suffered thrust, simultaneously, the locking rod 8 of fixedlying connected with rotating disk 11 moves in locating support, insert in the groove 12 of latch 6 its end, thereby will divide the latch locking of lock.
When security door need be opened, will lead lock 3 earlier and open, main dead bolt 4 resets.Simultaneously, touch panel 7, central siphon 10, rotating disk 11 and locking rod 8 reset rapidly under the effect of stage clip 13, open the branch lock again, and latch 6 is deviate from from doorframe, and security door promptly is opened.
