Abstract
The utility model provides a three-way theftproof door lock which comprises a lock body, a main lock plunger, an oblique tongue and a sliding bolt. A coupler knuckle is hinged in the lock body, a hooked part is arranged on the coupler knuckle, the coupler knuckle is linked with the sliding bolt through a transmission mechanism; when the sliding bolt acts, the hooked part on the coupler knuckle can extend out of the outer side the lock body or can completely retract in the lock body. The coupler knuckle is arranged on the common theftproof door lock, and the coupler knuckle is in linkage with the main lock plunger. When the safe-guard door lock is locked, the hooked part on the coupler knuckle is jointed with a corresponding structure on the door frame, so that the lock plunger cannot be easily separated from the lock plunger hole even a cracksman jimmies the door by force, and the theftproof performance of the common theftproof door lock is improved.
Description
Technical field
The utility model relates to a kind of safe-guard door lock, relates in particular to a kind of three-dimensional safe-guard door lock that has master latch, oblique tongue, sliding bolt.
Background technology
Safe-guard door lock mainly utilizes locking bolt on the door lock to be inserted on the doorframe set locking bolt hole, corresponding position and realizes when security door is locked.The locking bolt overwhelming majority on the existing safe-guard door lock is a straight-bar type, and is provided with the locking bolt hole in the doorframe corresponding position.If the robber uses force to force open the door by force locking bolt and locking bolt hole are separated, therefore, the safe-guard door lock theftproof performance of this structure has certain defective.
The utility model content
The purpose of this utility model provides the better three-dimensional safe-guard door lock of a kind of combined theftproof performance.
The purpose of this utility model can realize by following technical proposal: a kind of three-dimensional safe-guard door lock, comprise lock body, master latch, oblique tongue, sliding bolt, in lock body, be hinged with the hook tongue, has crook on the hook tongue, the hook tongue links by transmission mechanism and sliding bolt, when sliding bolt action, the extended lock body outside of the crook on the hook tongue or be fully retracted in the lock body.In this safe-guard door lock, general two up and down of sliding bolt is the mutually perpendicular direction setting between sliding bolt and the master latch, and master latch is when stretching out or be retracted in the lock body, and sliding bolt is interlock together and then, thereby in the locking that realizes on three directions between security door and the door lock.Sliding bolt is when action, make the hook tongue do corresponding motion by transmission mechanism, and on doorframe, be provided with hook tongue hole in the corresponding position of hook tongue, have in the hook tongue hole with the hook tongue on the crook positioning body that is interlockingly connected, when the hook tongue was inserted in the hook tongue hole, crook and positioning body on the hook tongue snapped together mutually.The motion that the motion that the hook tongue stretches out the lock body outside and master latch stretch out outside the lock body is synchronous, and both motions in being retracted into lock body also are synchronous.
This three-dimensional safe-guard door lock also can be done following further improvement:
Described hook tongue is two, and they lay respectively at the outside of master latch, oblique tongue.
Described hook tongue is located at the both sides of master latch symmetrically, and when the hook tongue stretched out the lock body outside fully, the crook on it was towards the outside of master latch.
Described transmission mechanism comprises supporting plate and pushing piece, and pushing piece is triangular in shape, and its drift angle place is articulated in the lock body, and two angles are hinged with an end and the sliding bolt of supporting plate respectively in addition, and the other end of supporting plate and hook tongue are hinged.
The position that is hinged with pushing piece on the described supporting plate is provided with guide finger, and described lock body is provided with gathering sill on the direction of motion of supporting plate, is inserted in the gathering sill to a tip-clearance of guide finger.
The other end dorsal part of described supporting plate is connected and stretches to the prerotation vane of lock body, and prerotation vane is " protruding " font near the end of lock body, and the position of this end has plush copper, and plush copper inserts in the set elongated slot in corresponding position on the lock body with gap.
Be provided with torsion spring in lock body, an end of torsion spring is connected an end of supporting plate versatilely, and the other end of torsion spring is connected on the torsion spring post set in the lock body versatilely.
Compared with prior art, the beneficial effects of the utility model are:
On existing common three-dimensional safe-guard door lock, install the hook tongue that is synchronized with the movement with master latch additional, follow master latch at the hook tongue and reach the lock body when outside, crook on the hook tongue can with the doorframe set limit body snapping in the tongue hole of rising to the bait, the hook tongue can limit the motion of lock body on the master latch direction by described limit body, also be not easy to make locking bolt and locking bolt hole to be separated even the robber uses force to force open the door by force, improved the theftproof performance of common three-dimensional safe-guard door lock.
Description of drawings
Fig. 1 is the internal construction schematic diagram of this three-dimensional safe-guard door lock, is clear its internal construction that shows, some component is removed.
Fig. 2 is the structural representation of supporting plate in this three-dimensional safe-guard door lock.
The specific embodiment
The specific embodiment of this three-dimensional safe-guard door lock is referring to shown in Figure 1.
The structure of this three-dimensional safe-guard door lock comprises lock body 1, is arranged on the master latch in the lock body 1, oblique tongue, interior safety tongue, two sliding bolts 12, on lock body 1, be hinged with hook tongue 7, has crook on the hook tongue 7, hook tongue 7 is connected with sliding bolt 12 by transmission mechanism, when sliding bolt 12 is followed the master latch motion, described hook tongue 7 is followed together and is synchronized with the movement, and promptly when master latch reached the outside of lock body 1, the crook on the hook tongue 7 was also followed together and opened towards the lock body outside; When master latch was retracted into lock body 1 inboard, the crook on the hook tongue 7 was followed together and is rotated towards lock body is inboard, and finally is fully retracted in the lock body 1.
Described hook tongue 7 is two, and they are located at the outside of master latch, oblique tongue, interior safety tongue symmetrically, and when hook tongue 7 reached the outside of lock body 1 fully, the crook above them was stretched to the outside of main lock body.Two hook tongues 7 link with two sliding bolts respectively by two sets of transmission mechanism.
