Description

Technical Field

[0001] The utility model relates to a novel mechanical password lock core and a mechanical password door lock. Background Art

[0002] Door locks are generally divided into mechanical door locks and electronic door locks. Although electronic door locks are becoming more and more popular, mechanical door locks still have a very large market demand due to their advantages such as low cost. Mechanical door locks are further divided into mechanical key door locks and mechanical password door locks. Mechanical key door locks require carrying a key with you, which is very inconvenient to use. In existing mechanical password door locks, when unlocking the door from the outside, after entering the correct password, you need to push the password seat inward to combine the password seat with the clutch, and then turn the password seat to unlock the door. When unlocking the door from the inside, regardless of whether the password is correct, you can directly turn the knob to unlock the door.

[0003] The disadvantages of this mechanical password door lock are that when unlocking the door from the outside, not only is it necessary to turn the password roller to enter the password, but it is also necessary to push it forward to unlock the door after the password is correct, and a spring is also provided to drive the password seat to reset. At this time, a certain gap needs to be left between the password seat and the door lock body. If the gap is large, the password seat will loosen, and if the gap is small, the password seat cannot be reset, which requires high assembly process and complicated processing and production process. Even if the assembly process is improved, it will still loosen due to wear of parts after long-term use. In particular, the operation of turning the password roller is required, which further increases the inconvenience of unlocking the door from the outside. Therefore, a new mechanical password lock cylinder and a mechanical password door lock are urgently needed to solve the above problems. Utility Model Content

[0032] Reference Figures 1 to 3 A novel mechanical password lock cylinder includes a lock cylinder housing 100, a dial wheel 200, a first connecting member 310, a second connecting member 320, a clutch member 400, a password assembly 500, an unlocking knob 600, a first reset member 710, and a second reset member 720;

[0033] The dial wheel 200 is rotatably connected to the lock cylinder housing 100 and is linked to the lock tongue;

[0034] The first connecting member 310 and the second connecting member 320 are respectively connected to the outer side and the inner side of the thumbwheel 200;

[0035] The password component 500 is connected to the clutch component 400;

[0036] The other side of the clutch member 400 is connected to the first connecting member 310;

[0037] The unlocking knob 600 is connected to the second connecting member 320, the dial 200 and the first connecting member 310 and abuts against the clutch member 400;

[0038] The first restoring member 710 abuts between the clutch member 400 and the password component 500;

[0039] The second restoring member 720 abuts between the second connecting member 320 and the unlocking knob 600;

[0040] The password assembly 500 can drive the clutch 400, the first connecting member 310 and the dial 200 to rotate when the password is entered correctly, so that the lock tongue is pulled out of the lock hole and unlocked; or the unlocking knob 600 can drive the second connecting member 320, the dial 200 and the first connecting member 310 to rotate when the clutch 400 is pushed out and separated from the first connecting member 310, so that the lock tongue is pulled out of the lock hole and unlocked.

[0041] In this utility model, the working principle is as follows:

[0042] 1. When unlocking the door from outside, if the password is entered incorrectly, the password assembly 500 is in a locked state. At this time, the password assembly 500 cannot rotate relative to the lock cylinder housing 100, and cannot drive the clutch 400, the first connecting member 310 and the dial 200 to rotate, and further cannot drive the dial 200 to unlock the lock body; when unlocking the door from outside, if the password is entered correctly, the password assembly 500 is in an unlocked state. At this time, the password assembly 500 can rotate relative to the lock cylinder housing 100, and can drive the clutch 400, the first connecting member 310 and the dial 200 to rotate, and further drive the dial 200 to unlock the lock body; it should be noted that the password assembly 500 can adopt an existing structure, which will not be described in detail here;

[0043] When the password of the password assembly 500 is correct, the clutch 400 and the first connecting member 310 are in a connected state. Therefore, when the password of the password assembly 500 is correct, the second connecting member 320, the dial wheel 200, the first connecting member 310, the clutch 400 and the password assembly 500 can be directly rotated relative to the lock cylinder housing 100 to achieve unlocking. When the password of the password assembly 500 is incorrect, the password assembly 500 cannot be rotated relative to the lock cylinder housing 100. At this time, it is necessary to push the unlocking knob 600 inward to push the clutch 400 and the first connecting member 310 to separate. Then, the unlocking knob 600 is rotated to drive the second connecting member 320, the dial wheel 200 and the first connecting member 310 to rotate, that is, the rotation of the dial wheel 200 links the lock bolt to be pulled out of the lock hole, and finally unlocking is achieved.

[0044] 3. The advantage of the present invention is that the above structure can reduce the complexity of the operation when unlocking outdoors and indoors, and has very good practicality.

[0045] In some embodiments, the unlocking knob 600 is connected to the first connecting member 310 , the thumbwheel 200 , and the second connecting member 320 via a first linkage structure 810 .

[0046] As a preferred embodiment of the first linkage structure 810, the first linkage structure 810 includes a first cross linkage groove 811 arranged on the first connecting member 310, the dial 200 and the second connecting member 320, and a first cross linkage block 812 arranged on the unlocking knob 600, and the first cross linkage block 812 is inserted into the first cross linkage groove 811.

[0047] In some embodiments, the clutch member 400 is coupled to the first connecting member 310 via a second linkage structure 820 .

[0048] As a preferred embodiment of the second linkage structure 820 , the second linkage structure 820 includes a plurality of linkage protrusions 821 circumferentially arranged on the clutch member 400 and a plurality of linkage grooves circumferentially arranged on the first connecting member 310 , and the linkage protrusions extend into the linkage grooves.

[0049] In some embodiments, the password assembly 500 is coupled to the clutch member 400 via a third linkage structure 830 .

[0050] As a preferred embodiment of the third linkage structure 830 , the third linkage structure 830 includes a second cross linkage groove provided on the clutch member 400 and a second cross linkage block 831 provided on the password assembly 500 , wherein the second cross linkage block 831 is inserted into the second cross linkage groove.

[0051] In some embodiments, a new type of mechanical password lock core also includes a first retaining spring clamped on the lock core shell 100 and the password assembly 500, which is used to limit the circumferential movement of the password assembly 500 relative to the lock core shell 100; a new type of mechanical password lock core also includes a second retaining spring clamped on the lock core shell 100 and the unlocking knob 600, which is used to limit the circumferential movement of the unlocking knob 600 relative to the lock core shell 100.
