Abstract
The utility model relates to an anti-theft door lock, which overcomes the abuse that the door of the kind is locked only in one direction; the utility model provides a lock with a geneva mechanism, capable of carrying the lock in three difference directions. The geneva mechanism is composed of a double-hook-shaped bolt, a rivet, a pin, a wobble plate with a double groove, a rotating shaft, and an upper and a lower slide blocks. When a door is locked, the rivet fixed on the double-hook-shaped bolt moves downwards along with the double-hook-shaped bolt, the other pin fixed on the upper slide block can be toggled by pushing the wobble plate with a double groove, the upper slide block carries out the reverse movement, and the locking function is reached thereby. The geneva mechanism can be arranged inside a button type door lock casing. The utility model is suitable for various house door; 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 device improvement that existing button door lock (having another name called super door lock) is increased different directions locking point mechanism, and it is applicable to 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 locking that can only a direction, antitheft fastness is poor, according to public security department's introduction, have that to be to use sled, impact method that latch plate and doorframe separation failure are entered the room in some theft case stolen, it is also less that real operation technique unblanks to crack a crib.
The purpose of this utility model just provides a kind of improvement that increases by two different directions locking point mechanism arrangement in existing button door lock, a kind of Geneva mechanism device that is provided with is provided, a kind of safe-guard door lock of three different directions of energy locking, this lock has the firm performance of higher pick-proof, protecting against shock.
The purpose of this utility model can realize by following measure: a kind of reversing arrangement of Geneva mechanism of safe-guard door lock, by the rivet (2) that is installed in double-hook type dead bolt (3) top, be installed in the rotating shaft (1) in the lock housing (9), double flute pendulum plate (15) and the pin (14) that is contained in top shoe (13) constitute.
The utility model has been set up the reversing arrangement of Geneva mechanism on the basis of existing similar door lock, can increase the locking point of two different directions; More than in addition part all in lock housing (9), simple in structure, easy for installation, overcome the disadvantage that existing similar door lock can only a direction of locking.So the utility model has realized locking the locking point of three directions, thereby has the firm performance of higher pick-proof, protecting against shock.
Concrete structure of the present utility model is provided by the following drawings:
Fig. 1: be lock body and sheave structural portion dress front view
The utility model describes embodiment in detail below in conjunction with accompanying drawing 1, a kind of Geneva mechanism reversing arrangement of safe-guard door lock, and by the driving link rivet, driven member double flute pendulum plate and pin three parts are formed.The driving link rivet portion is made of rivet (2), double-hook type dead bolt (3), handle gear (10), rivet (5), sliding block (6); At first rivet (2) is fixed on the top of double-hook type dead bolt (3), sliding block (6) is fixed on the bottom of double-hook type dead bolt (3) with rivet (5), and handle gear (10) matched in clearance is contained in the lock housing (9) can cooperate gearing with the tooth bar of double-hook type dead bolt (3).Driven member double flute pendulum plate portion is put plate (15), rotating shaft (1), lock housing (9) by double flute and is formed; Double flute pendulum plate (15) is with the top of rotating shaft (1) matched in clearance in lock housing (9), and plays gearing mutually with the rivet that is fixed on double-hook type dead bolt (3) (2), the pin (14) that is fixed on the top shoe (13).The pin part is by pin (14), top shoe (13), and last gusset piece (11) is formed; At first top shoe (13) and last gusset piece (11) are fixed together with rivet (12), then pin (14) are fixed on top shoe (13) below and are installed in double flute and put in the last groove of plate (15).
The reversing arrangement of the Geneva mechanism of second kind of safe-guard door lock is formed by being located at the laterally steering groove, double flute pendulum plate and top shoe three parts that match on the double-hook type dead bolt (3).Laterally steering slot part on the driving link double-hook type dead bolt (3): constituted by the laterally steering groove on the double-hook type dead bolt (3), handle gear (10), rivet (5), sliding block (6); At first rivet (2) is fixed on the lower end of double flute pendulum plate (15), sliding block (6) is fixed on the bottom of double-hook type dead bolt (3) with rivet (5), and handle gear (10) matched in clearance is contained in the lock housing (9) can cooperate gearing with the tooth bar of double-hook type dead bolt (3).Driven member double flute pendulum plate portion is put plate (15), rotating shaft (1), lock housing (9) by double flute and is formed; Double flute pendulum plate (15) is contained in the interior top of lock housing (9) with rotating shaft (1) matched in clearance, and the laterally steering groove that matches with the rivet (2) that is fixed on double flute pendulum plate (15), lower end laterally steering groove, pin (14) on top shoe (13) play gearing mutually.Top shoe part goes up gusset piece (11) by the lower end laterally steering groove on the top shoe (13), the pin (14) that is fixed on double flute pendulum plate (15) upper end and forms; At first top shoe (13) and last gusset piece (11) are fixed together with rivet (12), then pin (14) are fixed on the upper end of double flute pendulum plate (15) and are installed in the laterally steering groove of top shoe (13).
Operating principle of the present utility model and operation instruction:
When locking a door, handle gear (10) tooth bar of the moving double-hook type dead bolt (3) of the transfer clockwise moves downward, at this moment this part is two colludes in the hole of inserting latch plate (4), and pin the right-hand of door: the sliding block that at this moment is connected (6), rivet (7), second line of a couplet fishplate bar (8) also move downward the below of pinning door simultaneously; Meanwhile, the rivet (2) that is fixed on the double-hook type dead bolt (3) moves downward, the below skewed slot of stirring double flute pendulum plate (15) make this part around the shaft (1) clockwise rotate, at this moment the last square groove pushing pin of double flute pendulum plate (15) is followed closely (14), top shoe (13), rivet (12), last gusset piece (11) moves upward, reach the top of pinning door, realized pinning simultaneously the three parts of door.When opening the door, double-hook type dead bolt (3) moves upward and drives above associated part and all withdraw, and door is just opened.When double-hook type dead bolt (3) remake down motion, motion went round and began again.
Second kind of kind of drive is when locking a door, and handle gear (10) tooth bar of the moving double-hook type dead bolt (3) of the transfer clockwise moves downward, and at this moment this part is two colludes in the hole of inserting latch plate (4), pins the right-hand of door; At this moment, the sliding block that is connected (6), rivet (7), second line of a couplet fishplate bar (8) also move downward the below of pinning door simultaneously; Meanwhile, the laterally steering groove in double-hook type dead bolt (3) top moves downward, and stirs the rivet (2) of double flute pendulum plate (15) below, make this part around the shaft (1) clockwise rotate.At this moment the top pin (14) of double flute pendulum plate (15) is stirred the laterally steering groove of top shoe lower end, rivet (12), goes up gusset piece (11) and moves upward, and reaches the top of pinning door, has realized pinning simultaneously the three parts of door.When opening the door, double-hook type dead bolt (3) moves upward and drives above associated part and all withdraw, and door is just opened.When double-hook type dead bolt (3) remake down motion, motion went round and began again.
