Abstract

The utility model discloses a combined type mechanical cipher marble lock, which is composed of a common marble lock and a mechanical cipher lock, wherein a main body of the cipher lock is in parallel with a marble lock core 2 and a cipher wheel shaft 5 of the cipher lock and a shaft line of the marble lock core 2 are in the same plane surface. Two shaft directions are perpendicular mutually. The end of a lock bolt rod 7 which is shared by the marble lock and the cipher lock is hung and connected to a dialing fork 4 on the top end of the marble lock core. An involute slot 3 is arranged on the circumference of the outer wall of the marble lock core 2. The left end head of the cipher wheel shaft 5 is extended into the slot. The lockset can be unlocked by checking ciphers, and can also be unlocked by a key to rotate the lock core. In addition, ciphers can be changed conveniently under the condition that a lock body and a cipher subassembly are not disassembled.

Description

The combined mechanical password night lock

Technical field

The utility model relates to a kind of lockset, is specifically related to the lockset that a kind of mechanical cipher lock set and cylinder lock assembly combine.

Background technology

Traditional cylinder lock all is with key operated; Coded lock on the baggages or the coded lock on the combination lock generally can only be opened lock by password check.If lose key or forgotten password, just can only hope lock heave a sigh.

The utility model content

One of the purpose of this utility model be to provide a kind of both can be with key operated, the lockset that can open by password check again; Two of purpose is to take the password that lock body and password part just can be changed lockset easily apart.

The technical scheme that realizes above-mentioned first purpose is: the combined mechanical password night lock, form by common spring lock and mechanical code lock two parts, comprise lock body, can insert the lock cylinder of key, the dead bolt bar, lock ring and password wheel shaft and cipher wheel, the main body and the lock cylinder of described coded lock are arranged side by side, the password wheel shaft of coded lock is vertical mutually with the axis of lock cylinder, be contained between the last lower clamping piece of coded lock as cylinder lock and the shared dead bolt bar cramp of coded lock, the end of dead bolt bar is articulated on the shift fork on lock cylinder top, is with a spring that can make dead bolt bar return at the leading portion of dead bolt bar.

The technical scheme that realizes above-mentioned second purpose is: comprise above-mentioned first technical scheme, an involute groove is arranged on the outer wall circumference of described lock cylinder, a termination of password wheel shaft is stretched in this groove, and the password wheel shaft can move axially.

The utility model, also can be opened with key rotation lock core so this lockset not only can be opened by password check because the end of dead bolt bar is articulated on the shift fork on lock cylinder top; A termination of password wheel shaft extend in the involute groove on the lock cylinder outer wall circumference, when lock cylinder turns an angle, the password wheel shaft moves axially with regard to stressed, make on the password wheel shaft gear and with the dislocation of the cipher wheel of its engagement, like this, under the situation of not taking lock body and password part apart, just can change the lockset password easily.

Description of drawings

Below in conjunction with Figure of description and embodiment the utility model is described in further detail.

Fig. 1 is the structural representation of an embodiment of the utility model.

Fig. 2 is Figure 1A-A cut-away view.

Fig. 3 is a lock cylinder shape schematic diagram among Fig. 1.

The specific embodiment

In the embodiment shown in fig. 1, the combined mechanical password night lock is made up of common spring lock and mechanical code lock two parts, comprised two parts of common spring lock construction and mechanical cipher lock construction, promptly comprised lock body 1, can insert lock cylinder 2, dead bolt bar 7, lock ring 11 and password wheel shaft 5 and the cipher wheel 6 of key.The main body of coded lock is fixed on the lock body 1, and is arranged side by side with lock cylinder 2, and the axis of the password wheel shaft of coded lock 5 and lock cylinder 2 coexists in the plane, and two axially vertical mutually; Be in upper end in the lock body 1, be installed between the upper clip 8 and lower clamping piece 9 of coded lock as cylinder lock and the shared dead bolt bar 7 of coded lock, dead bolt bar 7 can horizontally slip between last lower clamping piece, the end of dead bolt bar 7 is articulated on the shift fork 4 on lock cylinder top, leading portion at dead bolt bar 7 is with a spring 10 that can make dead bolt bar return, as shown in Figure 2.

When stirring cipher wheel when having checked password, the spring below the lower clamping piece 9 is dead bolt bar 7 automatic jack-up, the dead bolt of dead bolt bar 7 front ends left be in the interior lock ring termination recess 12 of lockhole, thereby open lockset; When rotating lock cylinder 2, shift fork 4 drives dead bolt bar 7 and is moved to the left, and makes dead bolt leave lock ring termination recess 12, also can open lockset.

In order under the situation of not taking lock body and password part apart, just to change the lockset password easily, the utility model has an involute groove 3 on the outer wall circumference of lock cylinder 2, the left end head of password wheel shaft 5 is stretched in this groove, when lock core 2 clockwise rotates, the left end head to password wheel shaft 5 is just pushed up in the bottom of involute groove 3, cipher wheel is axially moved right, when this displacement be enough to make on the password wheel shaft gear and with the outer ring cipher wheel dislocation of its engagement and when breaking away from, just can readjust or set new password.

Rotate flexibly when the password check for the cipher wheel of this lockset, the utility model is provided with a snap-on push button 13 on the upper clip 8 of dead bolt bar, as shown in Figure 3.
