Abstract

The utility model discloses an element touch-tone lock core mechanism which is composed of lock latch twisting rod 1 which is provided with an annular disk 2, slide bolt mechanisms which can limit the rotation of the twisting rod 1, etc., wherein the twisting rod 1 is arranged in a lock core cavity 7; the annular disk 2 on the twisting rod 1 is provided with more than 2 through holes; each through hole is corresponding to one slide bolt mechanism to form a slide bolt element; in the slide bolt element, a slide bolt 9 is isopachous with the annular disk can be movably arranged in the through hole; one end of the slide bolt is pressed in the lock core cavity by a lower jacking block through a spring 12, and the other end of the slide bolt is connected with a slide touch-tone shifting mechanism with an inclined plane through an upper jacking block 13. The utility model has the advantage of convenient and reliable operation. The encode of the utility model can be changed at any time according to the needs, so the security is high.

Description

Unit button lock core mechanism

The utility model belongs to lockset and makes the field.

Present coded lock is the lock core structure of employing garden dish dialing generally, the topmost shortcoming that this structure exists is to change password at any time as required, therefore confidentiality is relatively poor, especially can not adapt to the needs that some users change frequently the occasion at (as various hotels, hotel).

A kind of button lock core structure that can change password as required of the design of the purpose of this utility model makes it to have more sign indicating number and advantage easy to use.

The purpose of this utility model is to realize by following design.

Unit button lock core mechanism, by the door bolt torsional pole with ring dish with spacing sliding bolt mechanism etc. is carried out in the torsional pole turn form, torsional pole places in the lock core cavity, and the ring dish on it has the through hole more than two; Each through hole is all corresponding with a sliding bolt mechanism and constitute a sliding bolt unit; In sliding bolt unit, movably be arranged in the through hole with the sliding bolt of ring dish uniform thickness, an end of sliding bolt passes through the spring roof pressure in lock core cavity by jacking block down; The other end of sliding bolt links to each other with an inclined-plane slip button shift mechanism by last jacking block.

After having adopted design as above, unlock operation can be finished easily, and password can be changed as required easily.

Description of drawings is as follows.

Fig. 1 is the outside drawing of the utility model torsional pole and ring dish thereof.

Fig. 2 is the lateral view of Fig. 1.

Fig. 3 outside drawing of the present utility model.

The longitudinal sectional view of Fig. 4 Fig. 3.

Fig. 5 is the installation drawing of sliding bolt unit.

Below in conjunction with accompanying drawing structure of the present utility model is described in further detail.

Fig. 1 and Fig. 2 are the basic structure of lock bolt torsional pole, 2 are connected in the ring dish on the

torsional pole

1,3,4,5,6 are through hole, 8 is lock bolt, it is contained in back (as shown in Figure 3) in the lock core cavity 7, can constitutes the utility model, lock bolt 8 fixedly is connected on the torsional pole by ring dish 2, if when not having other obstruction, with torsional pole 1 twisting of (a general and handle palmistry connects), lock bolt will produce the motion shown in arrow among Fig. 3, and other mechanism that drives lockset opens lockset, but when the turn that is subjected to torsional pole is restricted, torsional pole 1 just can't twist, and lock bolt 8 just can't move, and lockset can not be opened.

In conjunction with being clear that of Fig. 4 and Fig. 5, unit button lock core mechanism is made of the lock bolt torsional pole 1 with ring dish 2 and turn limits to torsional pole sliding bolt mechanism etc., torsional pole 1 places in the lock core cavity 7, ring dish 2 on it has four through holes (can see wherein two

holes

3 and 5 in Fig. 4,2, do not express on 4 liang of hole sectional views), each through hole all with a sliding bolt mechanism to corresponding and constitute a cunning bolt unit, two sliding bolt unit in Fig. 4, have been expressed, among sliding bolt unit, with the sliding bolt (9 of ring dish uniform thickness d, 10) movably place ring dish through hole (3,5) in, one end of sliding bolt is by jacking block 11 and spring 12 roof pressures are in lock core cavity down, and the other end of sliding bolt links to each other with the button shift mechanism with an inclined-plane slidably by last jacking block 13.

Inclined-plane slip press button mechanism is conventional, and its structure is identical with the inclined-plane slide mechanism that common garden pearl pen is used for telescopic pen core, different only be that the number on inclined-plane increases to some extent.When key 14 presses ratch 15, the interaction on the inclined-plane tooth 16 of ratch and the inclined-plane 18 of slipping ring 17, it is axially displaced that slipping ring 17 is produced, and the distance of displacement is in the position on different inclined-planes of slipping ring and difference according to the inclined-plane tooth, be symmetrical arranged the inclined-plane of two group of 5 terraced differing heights in slipping ring 17 can encircle generally speaking garden week, the corresponding diverse location from sliding stud shaft to displacement that determined of the height on inclined-plane, button is pressed for 14 times, and displacement increases by one section, down press again, increase by one section again, press 5 times after, slipping ring has changeed half cycle.The displacement of slipping ring 17 is by the sliding bolt 9 of passing to of last jacking block 13.Because sliding bolt and ring dish uniform thickness d, if the sliding bolt of each sliding bolt unit fully slips into the hole of ring dish interior (as the position of sliding bolt 10 in through hole 5 among Fig. 4), the turn restriction is just removed to corresponding ring dish through hole motion in this sliding bolt unit, the position when if the turn restriction is all removed to ring dish through hole in all sliding bolt unit (generally should be four or more) of formation lock core mechanism), the turn of the lock bolt torsional pole limit of promptly not being obstructed, but the lock bolt of turn torsional pole is opened lockset.As long as there is a sliding bolt unit to be in the turn constrained state, torsional pole all can not rotate, and lock bolt can't be opened.

When making, structure is just the same between each sliding bolt unit, different is that each sliding bolt can have different initial positions, this initial position has just determined the password of this unit, such as, the password of certain unit is " 5 ", promptly is illustrated in this cunning bolt unit and presses button 5 times and the sliding bolt of this unit can be pushed into fully and this unit accordingly in the ring dish through hole, makes this unit be in the opening that can make the torsional pole turn.

Correspondingly, change the initial position of sliding bolt, also just change the password of this unit,, can uropore be set in the one side (generally being the inner face of lockset) of lock core, as 19 among Fig. 3,20 for changing password easily.Following jacking block 11, sliding bolt 9 are made the garden ring-type of hollow, last lock dog 13 is made the two-section structure that is linked to each other by internal thread as shown in Figure 5, like this, just can elongate or shorten the length of jacking block by the spiral shell cutter groove 21 of last jacking block epimere by the middle part of uropore 19, following jacking block 11 and sliding bolt 9 with screwdriver, and change between the last head space of sliding bolt, change sliding bolt initial position thereby reach, change the purpose of password.

Though the utility model is considered with the design of class lockset, can be not limited to door lock when reality is used, and can be widely used in some other anti-thefting facility.
