Problems solved by technology

[0003] In order to overcome the problem that existing lock cores are rotated with keys, the present invention provides a kind of anti-prying and anti-theft lock core that can be opened immediately. This lock core is also mainly composed of lock shell 1, inner core 2 and key. There are two ways of forming the inner core 2; the first lock housing 1 is barrel-shaped, and the inner core 2 is packaged inside the lock housing 1, and is limited to telescopic sliding. 2 corresponds to the key hole, the other end is equipped with a cover 8, and a hole is opened in the cover 8 to make the inner core 2 protrude from the control bolt

specific Embodiment approach

[0007] The accompanying drawing is a schematic diagram of the internal structure of an anti-prying and anti-theft lock core of the present invention, taking double rows of marbles as an example; it can be seen from the accompanying drawings that the lock core is composed of three parts: a lock casing 1, an inner core 2, and a key 6. Shell 1 is provided with keyhole and pin hole, and blind pin 4 and spring 5 are arranged in the pin hole, and inner heart 2, back-moving spring 7, cover 8 are housed in lock shell 1 inside. Keyway, back-moving spring 7, and marble hole are arranged on inner core 2, and composition such as moving marble 3 is housed in the hole. When the lock matching key 6 is inserted into the keyhole, the pin 3 is moved to push all the blind pin 4 back into the bullet hole of the lock shell 1, the inner core 2 loses the control of the lock shell 1, and continues to push the key 6, and the key 6 pushes the inner core 2 Moving upwards, the upper part of the inner cor...

Abstract

The invention relates to a pickproof and burglarproof instant lock core. The lock core mainly comprises a lock shell, an inner core and a key, wherein the inner core is encapsulated inside the lock shell and is limited to retractably slide; and one end of the lock shell is provided with a keyhole corresponding to the inner core, and the other end of the lock shell is provided with a control bolt. When a lock is unlocked, the key is inserted into the inner core to separate the inner core from the lock shell and then is continuously pushed, the inner core is used for pushing the bolt to unlock the lock, and the key can be directly withdrawn.

Description

technical field [0001] The invention relates to a lock cylinder, in particular to an anti-picking and anti-theft instant lock cylinder. Background technique [0002] At present, well-known lock cylinders are all rotary, mainly made up of lock casing, inner core and key, need turn key to drive inner core rotation with hand during opening, inner core drives dead bolt again and opens lockset. Moreover, the lock cylinders are exposed and installed, and the keyholes are more than 2 mm wide. Thieves can easily open them with technology, or forcibly rotate the lock cylinder, or use a drill to destroy the lock cylinder, and the exposed lock cylinder is also easy to corrode, which reduces the quality of the lock. service life etc. Since the dead bolts are telescopic, controlling the telescopic dead bolts with a rotary lock cylinder requires additional conversion workpieces, which increases the cost and the failure rate. Contents of the invention [0003] In order to overcome the ...
