Embodiment 1

[0022] like figure 1 , 2As shown, this embodiment includes a bracket 1, a lock cylinder 2, a blade 3, an anti-violence transmission mechanism 4 and an alternate locking mechanism 5 between the lock cylinder and blades, wherein the bracket 1 is composed of a housing 11, a housing bottom plate 12 and a partition plate 13, divided into The partition plate 13 is positioned and fixed with the shell bottom plate 12 and the shell 11 through the double-ended studs 14 , the spacer shaft 62 , the sleeve 15 and the nut 16 . On the partition plate 13 of the bracket 1, there are centering shafts 17 and positioning shafts 18 that are perpendicular to the bottom plate 12 of the housing. The blades 3 are sleeved on the centering shafts 17 through the shaft holes 31. In the compartment 6 formed by the plate 13 and the separator 61, every four blades 3 are divided into two groups of matched two blades 32, and the matched two blades 32 are provided with spring grooves 33 and embedded in the opp...

Embodiment 2

[0025] like image 3 As shown, according to the working principle of embodiment 1, the lock core 2, the blade 3 and the corresponding lock core and blade alternate locking mechanism 5 can be provided with two or more groups according to the key, and all the lock cores 2 are only controlled by one anti-violence Transmission mechanism 4 drives and gets final product. The difference between this embodiment and Embodiment 1 is that this embodiment is provided with two groups of lock cylinders 2, blades 3 and an alternate locking mechanism 5 for lock cylinders and blades, and the shaft ends of the two lock cylinders 2 are respectively connected with an anti-violence transmission mechanism 4 The driven gear 48 and the second driven gear 410 are meshed through the second transmission gear 411 between the driven gear 48 and the second driven gear 410 . The present embodiment adopts the tooth-hole type key 8, and the blade 3 adopts a cylindrical contact 314, and the blade 3 is provide...

Embodiment 3

[0027] like Figure 4 As shown, according to the working principle of Embodiment 1, the blade key-reading lock cylinder can be configured to be opened by one key or multiple keys. The difference between this embodiment and Embodiment 1 is that this embodiment includes two sets of lock cylinders 2, blades 3 and an alternate locking mechanism 5 between lock cylinders and blades, and each set of blades 3 is respectively provided with a fancy key 7 for touching teeth. The contact 37 of tooth flower, each group of lock core 2 is jointly provided by an anti-violence transmission mechanism 4 to open or lock the active force of lock core, and each group respectively corresponds to a tooth flower key 7. In this embodiment, two fancy keys 7 are inserted into the corresponding keyholes 64 at the same time, and then the corresponding lock cylinders are opened or locked. The working principle of opening or locking the lock cylinders is the same as that of the first embodiment.

Abstract

The invention relates to the field of locks, provides a lock cylinder reading a key by blades, and aims to solve the problems that common blade lock cylinders are easily violently opened, lock cylinder blades independently exist as well as are free to shift and easy to crack, etc. The lock cylinder reading a key by blades comprises a support, wherein the blades and a lock cylinder are arranged on the support, the blades are sleeved on a spigot shaft via shaft holes, contacts are arranged at the key contact ends of the blades, and the contacts can be pushed by key thread patterns or thread holes and rotate along the spigot shaft to align at the blades; rotating holes are formed at the locking ends of the blades, the rotating holes are sleeved on the lock cylinder, lock cylinder grooves are arranged at the both sides of the lock cylinder, and blade lock cylinder locking teeth used for locking the corresponding lock cylinder grooves and corresponding to the key thread patterns or thread holes are arranged at the both sides of the rotating hole; and fan-shaped gears are arranged on the edges of the blades, and an anti-violence transmission mechanism, and a lock cylinder and blade alternate locking mechanism capable of locking the fan-shaped gears are further connected to the shaft head of the lock cylinder. The lock cylinder reading a key by the blades provided by the invention is strong in practicability and capable of effectively preventing violent opening; and the blades in the lock cylinder are locked before the lock cylinder is opened.

Description

technical field [0001] The invention relates to the field of locks, and in particular provides a blade key-reading lock cylinder. Background technique [0002] The principle of the ordinary blade-type lock cylinder is to insert the key into the keyhole of the lock cylinder first, and use the teeth with different angles on the inclined surface of the key to align the blades with different angles in the lock cylinder, and then the key drives the lock cylinder to rotate and open. Its structure is simple, has better safety factor in theory, but there are certain safety defects in several characteristics of known common blade type lock cylinders: one is the method that the key drives the lock cylinder to rotate and open, and the key may be replaced by the unlocking tool to insert the key into the key. The hole is violently driven to rotate and open the lock cylinder; the second is that the key teeth will leave imprints when the blades are aligned, and these imprints are easily ex...
