Abstract
The utility model belongs to a metal anti-theft door which is not only provided with a lock protecting mechanism with ciphers, but is also provided with a multi-door bolt mechanism. The utility model is composed of an inner door plate, an outer door plate, a cipher lock, the lock protecting mechanism with ciphers, the multi-door bolt mechanism, etc. A handle is rotated to drive a disc to rotate. A connecting rod connected with the disc together is used for enabling a plurality of door bolts to move along respective guide slots to drive a pulling bolt of a cipher mechanism simultaneously. If correct ciphers are inputted, the door bolt can be removed, and if wrong ciphers are inputted, the door bolt can not be pulled to open and a lock protecting plate can not be bounced to open. Therefore, the utility model can effectively prevent anti-theft doors from being prized and lock cores from being drilled or blocked.
Description
The utility model is a kind of metal anti-theft door with lock protecting cipher mechanism and multiple-bolt mechanism.
Popular in the market various security doors, basically be to adopt iron bar or metal door leaf etc., be installed on former wooden face outdoors, increased the difficulty of destroying door leaf, but its lockset is still continued to use traditional latch, lock core is exposed to the outside, not anti-drilling, do not possess the function that prevents that lockhole is blocked yet, and the door close after, have only the dead bolt position to link to each other with doorframe, be easy to door be pried open, cause unnecessary loss with instrument.
The purpose of this utility model is exactly to improve on the basis of this structure, designs a kind of pick-proof, anti-drilling and prevent the metal anti-theft door with lock protecting cipher mechanism and multiple-bolt mechanism that lockhole is stopped up by foreign matter.
Security door with lock protecting cipher mechanism and multiple-bolt mechanism, by security door, anti-theft puzzle lock, lock protecting cipher mechanism and multiple-bolt mechanism form, lock protecting cipher mechanism, coded lock is with being contained on the stiffener of lock section, and lock section stiffener and security door external door panel welded together, the combination disk of lock protecting cipher mechanism is exposed by the hole on the external door panel and is located, can stir combination disk at the door place, lock protecting plate is installed on the external door panel outside, top is sleeved on the fixed rotating shaft on the metal door, lock protecting plate be can rotate around the axis, the lock protecting plate bottom can be inserted in the metal door and can be opened by combination disk control, and lock core is tightly covered.
For preventing that security door from being pried open, the design has adopted multiple-bolt mechanism, being fixed in the rotating shaft on the handle on the external door panel and the disk of multiple-bolt mechanism links together, rotate the handle on the external door panel, can drive disk rotates together, by connecting rod that connects with disk and the hinge that is fixed on the external door panel, keeper can be moved along guide groove, disk rotates drivening rod simultaneously, also drive the pulling plug of Cipher mechanism, the password input correctly can make keeper move, if the password input error, handle is subjected to the connecting rod effect, can't rotate, can't draw back keeper and flick lock protecting plate, can't implement the behavior of unblanking, thereby the quilt that has prevented security door be prized.1,2,3 pair of the utility model describes in further detail with reference to the accompanying drawings.
