Abstract
The utility model relates to an anti-theft door lock, which overcomes the abuse that the lock of the kind can only carry out the lock in one direction; the utility model provides a lock with a gear and rack mechanism, capable of carrying the lock in three different directions. The mechanism is composed of a double-hook-shaped bolt, a gear, a rack, a rotating shaft, and an upper and a lower slide blocks. When the anti-theft door lock is locked, the rack fixed on the double-hook-shaped bolt moves downwards along with the rack, the gear is driven to rotate, the other rack is toggled to carry out the reverse movement, and the function of locking is reached thereby. The gear and rack mechanism, which is arranged inside a button type door lock casing, is suitable for various house doors; meanwhile, other functions of the original lock can not be affected.
Description
The utility model relates to a kind of safe-guard door lock, is the improvement that existing button door lock (having another name called super door lock) is increased different directions locking point mechanism arrangement, and it is suitable for various door locks.
Existing button door lock, generally be when locking a door, to reach the purpose of locking a door in the dead bolt insertion doorframe snap close plate hole, but can only be a direction locking, antitheft fastness is poor, according to public security department's introduction, have some to be to use sled, impact method that latch plate and doorframe separation failure are cracked a crib in stolen, it is stolen less really to enter the room with skilled unlocking.
The purpose of this utility model is to increasing the improvement of two different directions locking point mechanism arrangement in the existing button door lock, a kind of pinion and rack reversing arrangement is provided, a kind of safe-guard door lock of three different directions of energy locking makes this lockset that higher pick-proof be arranged, the firm performance of protecting against shock.
The purpose of this utility model can realize by following measure: a kind of pinion and rack reversing arrangement of safe-guard door lock, by the tooth bar (2) that is installed on the double-hook type dead bolt (3), be installed in the rotating shaft (1) in the lock housing (9), gear (14), tooth bar (13) and sliding block (6) constitute.
When locking a door, double-hook type dead bolt (3) inserts in the hole of latch plate (4) when moving downward, and pins the right-hand below of also pinning door of door; Meanwhile, be fixed on tooth bar (2) driven gear (14) rotation on the double-hook type dead bolt (3), and then promote another tooth bar (13) and upper junction plate (11) and move upward and pin the top of door, realized tripartite locking.When opening the door, above-mentioned part movement direction is opposite, and the locking of three directions is opened, and realizes unblanking purpose.
The utility model has been set up the pinion and rack reversing arrangement on the basis of existing similar door lock, can increase the locking point of two different directions; Above part is all in lock housing (9), and is simple in structure, easy for installation, overcome the drawback that existing similar door lock can only a direction of locking.The utility model has been realized the locking point of three different directions of energy locking, thereby has properties such as higher pick-proof, protecting against shock.
Concrete structure of the present utility model is provided by the following drawings.
Fig. 1 lock construction and pinion and rack reversing arrangement front view
The utility model describes embodiment in detail below in conjunction with accompanying drawing 1.A kind of pinion and rack reversing arrangement of safe-guard door lock as shown in Figure 1, by the driving link tooth bar, driven member gear two parts are formed.The driving link section of rack is by double-hook type dead bolt (3), handle gear (10), and tooth bar (2), sliding block (6), rivet (7), lower connecting plate (8) is formed.At first tooth bar (2) is fixed on double-hook type dead bolt (3) top, sliding block (6) is fixed on the bottom of double-hook type dead bolt (3) with rivet (5), handle gear (10) matched in clearance can cooperate transmission with the tooth bar of double-hook type dead bolt (3) in lock housing (9), lower connecting plate (8) is fixed on the sliding block (6) with rivet (7).Driven member part is by rotating shaft (1), gear (14), and tooth bar (13), rivet (12), upper junction plate (11) and lock housing (9) are formed; At first gear (14) and rotating shaft (1) matched in clearance are contained in the interior top of lock housing (9), and play gearing mutually with tooth bar (13), upper junction plate (11) is fixed on the tooth bar (13) with rivet (12).
Operating principle of the present utility model and operation instruction:
When locking a door, handle gear (10) clockwise rotates, and the tooth bar of stirring double-hook type dead bolt (3) moves downward, and at this moment the two of this part collude in the hole of inserting latch plate (4), pin the right-hand of door; At this moment the sliding block of Lian Jieing (6), rivet (7), lower connecting plate (8) also moves downward, and pins the below of door; Meanwhile, be fixed on tooth bar (2) on the double-hook type dead bolt (3) move downward handsetting gear (14) make this part around the shaft (1) make clockwise direction and rotate, then tooth bar (13) moves upward, and pins the top of door.When opening the door, handle is held wheel (10) inhour and is rotated, and double-hook type dead bolt (3) moves upward, and other correlated parts is all withdrawn, and door is just opened.When double-hook type dead bolt (3) was gone up motion down again, motion went round and began again.
Claims (1)
1, a kind of safe-guard door lock with double-hook type dead bolt, mainly by lock housing (9), double-hook type dead bolt (3), handle gear (10), latch plate (4) gear (14) is formed, and it is characterized in that: set up a pinion and rack reversing arrangement in the inside of lock housing (9); The device of this mechanism is by gear (14), tooth bar (2), and tooth bar (13) rotating shaft (1) constitutes; When double-hook type dead bolt (3) when moving up and down, tooth bar (2) driven gear (14) that is fixed on this part rotates, and stirs tooth bar (13) and other component motion of cooperating is made dead bolt and used.
