Example Embodiment

[0046] Please refer to Figure 1 to Figure 10 As shown, it shows the specific structure of the preferred embodiment of the present invention. It is a key, lock cylinder, and electromagnetic lock. By improving the structure of the key and lock cylinder, it solves the problem of the anti-theft performance of the existing marble lock. High question.

[0047] (See Figure 7 Shown) The key includes an unlocking portion 10 and a holding portion 20; in the embodiment of the present application, the holding portion 20 is provided at the end of the unlocking portion 10, and the surface of the unlocking portion 10 is provided with a through unlocking portion 10 The slot 11 at the head end; both sides of the slot 11 are recessed with concave surfaces 12 for restricted marbles, and the concave surface 12 has an inclined surface. Specifically, the unlocking portion 10 is provided in a rectangular structure, and the slot is provided on the top surface of the unlocking portion. The two sides o...

Abstract

The invention discloses a key, a lock cylinder and an electromagnetic lock. The key comprises an unlocking part and a holding part, wherein an inserting slot is formed in the unlocking part, concave surfaces are formed on the two sides of the inserting slot, and inclined plane parts are arranged on the concave surfaces; the lock cylinder comprises a handle, a rotating drum, an upper pin tumbler, alower pin tumbler, a spring and a striking plate, and conical inclined planes matched with the inclined plane parts of the key are arranged at the bottom of the lower pin tumbler. The conical inclined planes are arranged on the lower pin tumbler of the lock cylinder, and the concave surfaces are formed at the unlocking part of the key and provided with the inclined planes; the conical inclined planes and the inclined plane parts are matched to limit the height to rotate the rotating drum for unlocking or unlocking; and the conical inclined planes and the inclined plane parts are matched to determine the position, by the aid of instability of the inclined plane part structures, specific structures of the key and the lower pin tumbler are difficult to recognize, the probability of detectedunlocking is greatly reduced, safety is enhanced, and in fact, it is difficult for lawless persons to detect depth of the concave surfaces and the shape of the inclined plane parts of the key and counterfeit the key, so that the anti-theft performance of the pin tumbler lock is improved.

Description

technical field [0001] The invention relates to the technology in the field of locks, in particular to a key, a lock cylinder and an electromagnetic lock. Background technique [0002] The pin lock is a commonly used lock cylinder at present, and it has a plurality of cylindrical parts of different heights inside, called a lock spring, also known as a pin or a bead. Its working principle is to use the lock spring to lock the lock cylinder. When the correct key is inserted into the lock, each lock spring is pushed to the same height, and the lock cylinder is released. After the lock cylinder rotates, the lock will be opened. [0003] Generally, the bullet lock uses the bottom surface of the marble and the concave bottom of the key to determine the position. When the height of the marble matches the concave bottom of the key correctly, the lock cylinder can be turned to unlock or close the lock; The bottom surface of the key recess is matched, which is relatively simple and e...
