Embodiment 1

[0033] The invention provides an anti-drilling electronic lock cylinder, such as Figure 1-3 As shown, including the lock housing, at least two T-shaped contacts 1370 and at least two anti-drilling pins 1390 are arranged in the middle of the end face of the lock housing. The T-shaped contacts 1370 and the anti-drilling pins 1390 are made of alloy materials, and the T-shaped contacts The ratio of the sum of the areas of the 1370 and the anti-drilling pin 1390 on the end surface of the lock housing to the area of ​​the end surface of the lock housing is between 1 / 10 and 2 / 3.

[0034] Wherein, if the sum of the areas of the T-shaped contact 1370 and the anti-drilling pin 1390 on the end surface of the lock housing accounts for less than 1 / 10 of the area of ​​the end surface of the lock housing, then in actual use, the overall anti-drilling effect of the lock cylinder will be reduced. The effect improvement is low, and the electric drill can quickly penetrate the end face of the l...

Embodiment 2

[0038] For the anti-drilling electronic lock cylinder described in Embodiment 1, in this embodiment, the T-shaped contact 1370 includes a cylindrical head 1371 and a rod 1372, the diameter of the head 1371 is larger than the diameter of the rod 1372, and The bottom end surface of the lock housing is provided with T-shaped slots 1224 corresponding to the number of T-shaped contacts 1370, and the T-shaped slots 1224 match the structure of the T-shaped contacts 1371, and the T-shaped contacts 1370 are inserted into the T-shaped slots 1224 In the middle, the head 1371 remains flush with the bottom surface of the lock housing around it. The diameter of the T-shaped contact 1370 is between 1.5mm-3mm. In this embodiment, the diameter of the head 1371 of the T-shaped contact 1370 is between 1.5mm-3mm, and the diameter of the rod 1372 is larger than that of the head. The part 1371 is small, reducing the production cost while ensuring the effect. In the test, if the diameter of the T-s...

Embodiment 3

[0042] As the anti-drilling electronic lock cylinder described in Embodiment 2, in this embodiment, combined Figure 4 and Figure 5 As shown, it includes a lock case and a drive assembly and a transmission assembly arranged inside the lock case. The transmission assembly includes a driven gear 1110 , a helical drive gear 1120 , a drive circlip 1130 and a limit block 1140 . The helical drive gear 1120 includes a gear part 1121 And the worm part 1122, the driven gear 1110 is engaged with the gear part 1121 for transmission, the worm part 1122 is arranged on the side of the gear part 1121 facing the drive assembly, the helical drive gear 1120 drives the movement of the limit block 1140 through the driving circlip 1130, and the lock The housing is provided with a locking component for switching the closed / open state of the lock, the limit block 1140 is used to limit the movement of the locking component to realize the locking / opening of the lock cylinder, and the driving componen...

Abstract

The invention provides an anti-drilling electronic lock cylinder. The anti-drilling electronic lock cylinder comprises a locking shell, at least two T-shaped contacting heads and at least two anti-drilling pins are arranged in the middle of the end surface of the locking shell, alloy materials are adopted by the T-shaped contacting heads and the anti-drilling pins, and the sum of the area of the T-shaped contacting heads and the anti-drilling pins accounts the area of the end surface of the locking shell is between 1 / 10 and 2 / 3. According to the anti-drilling electronic lock cylinder, the T-shaped contacting heads and the anti-drilling pins are arranged on the end surface, high strength alloy structures are adopted by the T-shaped contacting heads and the anti-drilling pins, the drilling resistance of the lock cylinder is greatly improved under the condition of reducing the overall cost of the lock cylinder.

Description

technical field [0001] The invention relates to the field of electronic locks, in particular to a drill-resistant electronic lock cylinder. Background technique [0002] In daily life, door locks are an important barrier to ensure property safety and privacy security. With the development of society, the requirements for door locks in terms of safety and convenience are also increasing. Electronic locks, as a common lock, are generally It consists of two major parts, the electronic drive part and the mechanical transmission. The drive of the electronic drive part drives the mechanical transmission part to realize the functions of unlocking and locking. [0003] However, the anti-drilling ability of the current anti-drilling electronic lock cylinder is low. When using an electric drill to pick the electronic lock cylinder, the ordinary electronic lock cylinder will be destroyed within three minutes under the violent disassembly of the electric drill. The time is short, and t...
