Problems solved by technology

[0003] The existing tumbler locks are simple in principle and poor in anti-theft performance. When performing technical opening, they can be opened in a short time. The complexity of the arrangement and the installation of a self-locking device at the entrance, but because the principle has not changed, it can still be opened when it is technically opened, and the anti-theft performance is poor.

Embodiment 1

[0033] Embodiment 1, a new anti-technical opening tumbler lock cylinder, including a lock body 1, a lock cylinder 2, a lock rod 3 and a key 20, the lock body 1 is provided with a rotatable lock cylinder 2, and the lock cylinder 2 The middle part is provided with a fixedly connected lock bar 3, the lock bar 3 passes through the outside of the lock body 1, and the lock core 2 positioned outside the lock bar 3 is provided with a number of evenly distributed lock holes 8;

[0034] The key 20 is composed of a handle 23, a key body 21 and a key shaft 22. The bottom of the key body 21 is provided with a number of evenly distributed key shafts 22 that match the lockhole 8. The outside of the key shaft 22 is provided with a number of uniform Distributed key slots 26.

[0035] Preferably, a handle frame 24 is provided in the middle of the handle 23 , and a first protrusion 25 is provided on the handle 23 , and a corresponding second protrusion 27 is provided on the outer surface of the ...

Embodiment 2

[0051] The same as embodiment 1 is no longer repeated, and the difference with embodiment 1 is:

[0052] The first upper pin 6 and the first spring 17 are not provided in one or more of the first upper bullet slots 18 . The first springs and the first upper pins in the corresponding one or more first upper bullet slots in different lock holes are removed, thereby forming a similar " "False first pin", so that the unlocker cannot accurately determine the exact position of the "false first pin". When using technology to open, push the "false first pin" to the misplaced position, which will push the "false first pin". "One click" into the first upper bullet slot, thereby locking the lock cylinder and locking cylinder, increasing the difficulty of anti-technical opening, and setting a fourth spring in the corresponding first lower bullet slot to connect with the adjustment rod, using the fourth spring Increase the damping of the "false first pinch" when pushing to confuse the ope...

Embodiment 3

[0054] The same as embodiment 1 is no longer repeated, and the difference with embodiment 1 is:

[0055] At the bottom of one or more of the locking holes 9, the second lower bullet slot 14 and the second lower pin 10 are no longer provided, and the corresponding second upper bullet slot 16 and second upper pin 11 are removed at the same time. Remove the second lower bullet groove and the second lower pin at the bottom of one or more lock holes, and remove the corresponding second upper bullet groove and second upper pin at the same time, thus forming one or more "false pressing blocks" , so that the unlocker cannot accurately determine the exact position of the "false pressing block", which further increases the difficulty of preventing technical opening.

Abstract

The invention discloses a novel pin tumbler lock cylinder capable of avoiding technical opening. The novel pin tumbler lock cylinder comprises a lock body, a lock cylinder, a lock rod and a key, and is characterized in that the rotatable lock cylinder is arranged in the lock body, the lock rod in fixed connection is arranged in the middle of the lock cylinder, the lock rod penetrates through the outer side of the lock body, and multiple evenly-distributed lock holes are formed in the position, located on the outer side of the lock rod, of the lock cylinder; the key is composed of a handle, a key body and key rods, the multiple evenly-distributed key rods matched with the lock holes are arranged at the bottom of the key body, and multiple evenly-distributed key grooves are formed in the outer sides of the key rods; and the key holes are distributed around the lock rod in a cylindrical distribution manner, the loch holes are located in different positions, and therefore during technicalopening, an operator cannot control the lock holes in different positions at the same time, and technical opening is effectively avoided.

Description

Technical field: [0001] The invention relates to the technical field of tumbler locks, in particular to a novel anti-technical opening tumbler lock cylinder. Background technique: [0002] A pin tumbler lock, also known as a pin tumbler lock, bead lock, bolster lock or pin bolt lock, is one of the most common lock structures. The principle is to use multiple cylindrical parts of different heights (called lock springs, pins or beads) to lock the lock cylinder. When the correct key is put in, each lock bolt is pushed to the same height, and the lock cylinder is released. [0003] The existing tumbler locks are simple in principle and poor in anti-theft performance. When performing technical opening, they can be opened in a short time. The complexity of the arrangement and the installation of a self-locking device at the entrance, but because the principle has not changed, it can still be opened when it is technically opened, and the anti-theft performance is poor. Inventio...
