The utility model has the advantages of reasonable structure, smart design, two independent lock mechanisms, strong applicability and convenient use.
Description
The utility model relates to a kind of door lock, especially a kind of multi-function door lock that is applicable to double door.
Along with the raising day by day of living condition, people's awareness of safety is also being strengthened, and also more and more higher to the requirement of security door, the safe-guard door lock kind that is used for single door at present is more, but it is then less to be used for the kind of safe-guard door lock of double door.Mostly adopt existing built-in lock, promptly use earlier or latch fixedly is equipped with locked groove down Yishanmen, the Yishanmen that again another is equipped with dead bolt is shut and is got final product, and pick-proof, crashworthiness are relatively poor.At this situation, this case inventor had once declared a kind of stealthy safety door latch that is used for double door in 98 years, now authorize, the patent No. is ZL98232606.8, and primary structure is: drive lever by rotating shaft, the little driving lever that vertically is connected by the lever end drives shift fork, drive the locking bolt that is connected with it by shift fork and move, have draw-in groove on the locking bolt, the dop of being controlled by lock body can snap in this draw-in groove, thereby the pinning keeper has the anti-tamper-resistant function of dialling.But by on probation, find that this door lock function is single, also convenient inadequately during use, need both hands to move simultaneously, just can open or lock.
A kind of Multifunction door lock that is used for double door that the purpose of this utility model designs at existing problem in the above-mentioned prior art just, this door latch structure is reasonable, designs ingeniously, has independently mechanism for locking up of twice, can satisfy the needs of different situations, very easy to use.
The purpose of this utility model realizes by following scheme: the multi-function door lock that originally is applicable to double door comprises horizontal bolt, bolt stationary pipes, wherein: by an affixed bull stick and a crank in the rotating shaft of lock core control, the other end of bull stick is connected with driving lever, but driving lever is arranged on and is fixed in the shift fork that horizontal door latches and upper and lower displacement; Crank is arranged in the jaw of dehiscing to clamp that is fixed on the door-plate, dehisce to clamp two pincers shank end portions be not connected with pull bar and spring, the other end of spring be connected with can with the bolt up and down that has the inclined-plane of last lower door frame groove fit.
In the utility model, described horizontal bolt and corresponding bolt stationary pipes are formed by two, also can be designed to three as required and follow, and further increase its intensity.
The operating principle of this multi-function door lock is: close Yishanmen earlier, close another fan again and have the door of bolt up and down, because the end of bolt is the inclined-plane up and down, when door is closed, be connected spring on the bolt up and down by the impact utilization of door and make up and down that bolt is inserted in the groove of offering on the doorframe, before Yishanmen fixedly be to realize by the interlock on two every limits, promptly reached the purpose that the first step is locked by such cooperation; Its unlatching is to drive crank by the lock core rotating shaft, and the jaw of dehiscing is opened, and drives pull bar and spring and makes bolt retraction up and down, reaches the purpose of opening door.The realization that second step locked is by rotating shaft interlock bull stick, thereby drive laterally advancing of the horizontal bolt of shift fork realization, horizontal bolt is pierced in the bolt stationary pipes, finish the purpose of locking for the second time, its unlatching is that the backward rotation by rotating shaft retreats horizontal bolt to realize.
The utility model preferably is located at it in interlayer of door when installing and using, and motion of mechanism only is that the rotation by lock core and coupled rotating shaft realizes.
The utility model compared with prior art has the following advantages:
1,, and all be arranged in the interlayer of door because the twice mechanism for locking up is arranged, not only specious, also be difficult for destroyedly, and the twice locking device can be combined as a whole two fan doors effectively securely, pick-proof, tamper-proof has guaranteed the safe antitheft function of door.
2, the twice mechanism for locking up of this door lock can be respectively applied for different situations, locks conveniently because of the first road mechanism for locking up, can be used for general locking when temporarily going out; Just utilize the second road mechanism for locking up strengthening its anti-theft feature if go out for a long time, so the twice mechanism for locking up is used the demand that can satisfy user's different situations easily.
3, this door latch structure is reasonable, design ingenious, have twice separate can cooperatively interact again use mechanism for locking up form, can satisfy the needs of different situations, very easy to use.
Accompanying drawing is a structural front view of the present utility model.
The utility model is described further below in conjunction with accompanying drawing: the multi-function door lock that originally is applicable to double door comprises horizontal bolt (1), bolt stationary pipes (2), wherein: by rotating shaft (a 9) soil affixed bull stick (10) and a crank (8) of lock core control, the other end of bull stick (10) is connected with driving lever (7), driving lever (7) be arranged on the shift fork (11) that is fixed in horizontal door and latches but in and upper and lower displacement, described horizontal bolt (1) and corresponding bolt stationary pipes (2) are formed by two, and shift fork (11) is fixed between the two horizontal bolts (1).Crank (8) is arranged in the jaw that is fixed in the pincers (6) of dehiscing on the door-plate, dehisce pincers (6) two pincers shank end portions be not connected with pull bar (5) and spring (4), the other end of spring (4) be connected with can with the bolt up and down (3) that has the inclined-plane of last lower door frame groove fit.
