Upper end at described rotating cabin connects one first rotating shaft, connects an ellipse connect in the first rotating shaft upper endAxle, its lower end is directly connected with key handle;
Described ellipse connecting axle upper end is connected with the second rotating shaft, and the second described rotating shaft and rotary handle connectConnect, and move with rotary handle.
Further, on the second described rotating shaft, be provided with a square key, square hole be set on rotary handle, square key withSquare hole matches.
Further, a flat mouth pad and a nut are also set above described square hole, in order to fixing described rotationHandle and the second rotating shaft.
Further, at the sidepiece of described fixed bin, one alignment pin is also set, at the sidepiece of rotating cabin, one location is setPin-and-hole.
Further, be key handle accommodating cavity at the cavity on the top of described rotating cabin, key handle is placed in this handIn handle accommodating cavity, and key handle contacts with the expansion spring on its top.
Further, described fixed bin and positioning splint are integrated structure.
Beneficial effect of the present invention is compared with prior art, and door lock safety guard plate of the present invention is arranged on door lockOutside, structure is simpler, easy to operate; Can effectively prevent that other unlocking tool from unblanking, safe and effective.
Brief description of the drawings
Fig. 1 is the structural representation of door lock safety guard plate of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, technical characterictic and the advantage with other above-mentioned to the present invention are described in more detail.
Refer to shown in Fig. 1, it is the structural representation of door lock safety guard plate of the present invention, and it comprises lockset locating clipPlate 1, it covers on tapered end the bottom of this protective cover; One fixed bin 2, it is arranged on the top of positioning splint 1, in the middle of it, arranges oneThe first cavity 2, a first vertical gap is offered in left side, and in the present embodiment, described fixed bin 2 and positioning splint 1 are oneBody structure. One rotating cabin 3 is also set in described fixed bin 2, and described rotating cabin 3 inside are the sky of a containing keyChamber, also arranges a second vertical gap in the left side of rotating cabin 3, in the time that the first gap and the second gap are docking together, and keySpoon enters in the cavity in rotating cabin 3 from this gap. In the present invention, rotating cabin 3 can half-twist, when the first gap andWhen the second gap staggers, play sealing function.
At the sidepiece of fixed bin 2, an alignment pin 4 is also set, at the sidepiece of rotating cabin 3, a dowel hole is set, work as alignment pinWhile rotating to dowel hole, realize location.
Be key handle accommodating cavity at the cavity on rotating cabin 3 tops, key handle 5 is placed in this handle accommodating cavity, andKey handle 5 contacts with the expansion spring 6 on its top, and it is arranged in the internal cavities of rotating cabin 3, in order to control rotating cabin 3Automatic rotation, in the time rotating to certain angle, expansion spring elongates or shortens, under the effect of spring force, at the beginning of rotating cabin 3 is got back toBeginning position.
Connect one first rotating shaft 7 in rotating cabin 3 upper ends, in the present embodiment, its axle that is 2mmX8, its driven rotary90 ° of storehouse 3 left rotation and right rotation, connect an ellipse connecting axle 8 in the first rotating shaft 7 upper ends, and its lower end is directly connected with key handle 5Connect. In the present invention, rotary handle 9 energy left rotation and right rotation and front and back push-and-pulls, complete the function of unblanking, and its front portion is connected with ellipseAxle 8 connects.
Described ellipse connecting axle 8 upper ends are connected with the second rotating shaft 10, in the present embodiment, and the second described rotationAxle is the axle of 4mmX8, and it drives key handle 5 to play the function of unblanking, and in the time putting key into, it is Finite rotation, when notWhile putting key into, it is unlimited rotary.
The second described rotating shaft 10 is connected with rotary handle 9, and it is arranged on the transverse slat of rotary handle 9 inside,On two rotating shafts 10, be provided with a square key 11, square hole 12 is set on rotary handle 9, in the time turning to certain angle, Liang ZhejieClose, play the effect of location.
One flat mouth pad 13 and a nut 14 are also set above square hole 12, in order to fixing rotary handle 9 and the second rotating shaft10。
In use, first rotate rotary handle 9, drive the second rotating shaft 10, and the ellipse being attached thereto connectsAxle 8, the first rotating shafts 7, and then driven rotary storehouse 3 rotates, in the time that the first gap and the second gap are docking together, key is from thisIn gap, enter in the cavity in rotating cabin 3; Due to now, ellipse connecting axle 8 contacts with the key handle 5 of bottom, continuesRotate rotary handle 9, it drives ellipse connecting axle 8, key handle 5 to rotate, and then open door lock; Reverse rotation, can take outKey. In the time of door lock locking, the first gap and the second gap stagger, and key can not insert wherein, form door lock protective cover, preventSteal lock.
The foregoing is only preferred embodiment of the present invention, is only illustrative for invention, and nonrestrictive.Those skilled in the art is understood, and in the spirit and scope that limit, can carry out many changes to it in invention claim, amendment,Even equivalence, but all will fall within the scope of protection of the present invention.
