The key includes a plurality of rotating pieces and a main shaft, and the rotating pieces are fixed on the main shaft through bearings. Above, the lock body is provided with a key insertion hole, and along the inner key insertion hole of the lock body, there are cross-shaped rotating blocks with the same number as the rotating pieces. There is a spring; the key is inserted into the keyhole and then rotated. The key rotates along each rotating block inside the lock body from a plane to a cross shape or from a cross shape to a plane. After the rotation is completed, the rotating block pushes up the marble to open the lock cylinder. The invention has the advantages of simple structure, convenient use, good anti-theft effect, safety and reliability; it can be used for various mechanical types of external hanging and internal anti-theft locks.

Description

New anti-theft mechanical lock cylinder

technical field

The invention relates to the field of mechanical pin locks, in particular to a novel anti-theft mechanical lock cylinder. the

Background technique

The lock cylinder is the main part that controls the opening of the lock. It is the heart of the lock. It refers to the core part that can be turned and driven by the key to move the lock. The main function of the lock cylinder is to transmit the torque through the head, thereby driving other parts of the lock to achieve unlocking and locking. Padlocks, drawer locks, door locks and bicycle locks have different cylinder head structures and different ways of transmitting torque, but the functions are the same.

Existing mechanical tumbler lockset is widely used because of simple structure, easy to use. However, the lock cylinder rotor of this type of mechanical pin lockset is an integral structure, so as long as a suitable tool is found and the lock cylinder body is used as a support point, the lockset can be opened relatively easily, providing opportunities for some lawbreakers to take advantage of, causing great harm. big security risk. The current structure of the lock cylinder is generally a mechanical lock cylinder with a spring pin, the matching key is easy to be copied, and the opening password of the common key type safe is easy to forget.

Contents of the invention

The technical problem solved by the present invention is to provide a new anti-theft mechanical lock cylinder to solve the problems raised in the above-mentioned background technology.

The technical problem solved by the present invention adopts following technical scheme to realize:

The new anti-theft mechanical lock cylinder includes a key and a lock body. The key is the same as the existing key, which is a flat key or a cross-shaped key. The key includes a plurality of rotating pieces and a main shaft, and the rotating pieces are fixed on the main shaft through bearings. Above, the lock body is provided with a key insertion hole, and along the inner key insertion hole of the lock body, there are cross-shaped rotating blocks with the same number as the rotating pieces. There is a spring; the key is inserted into the keyhole and then rotated. The key rotates along each rotating block inside the lock body from a plane to a cross shape or from a cross shape to a plane. After the rotation is completed, the rotating block pushes up the marble to open the lock cylinder.

Further, the rotating piece of the key is provided with convex and concave edges.

Further, the rotation angle of each rotating block in the lock body of the rotating piece of the key is cross-shaped. the

Further, there are at least 2 rotating pieces, and the lengths of each rotating piece are equal.

Further, the rotating pieces have different lengths.

Beneficial effect:

The invention has the advantages of simple structure, convenient use, good anti-theft effect, safety and reliability; it can be used for various mechanical types of external hanging and internal anti-theft locks.

Detailed ways

In order to make the implementation technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further elaborated below in conjunction with specific illustrations.

As shown in Figures 1 to 3, the new anti-theft mechanical lock cylinder includes a key 5 and a lock body 2. The key 5 is the same as the existing key, which is a flat key or a cross-shaped key. The key 5 includes a plurality of rotating pieces. 6 and the main shaft 7, the rotating piece 6 is fixed on the main shaft 7 through a bearing, the lock body 2 is provided with a key insertion hole, and along the lock body 2 internal key insertion holes are provided with the same number of crosses as the rotating piece 6 Type rotary block 3, each of the above-mentioned rotary blocks 3 is provided with a pin 4, and the pin 4 is provided with a spring 1; the key 5 is inserted into the keyhole and rotated, and the key 5 is rotated along the plane of each rotary block inside the lock body. Become a cross or rotate into a plane by the cross, after the rotation is completed, the rotating block pushes up the pin 4, and the lock cylinder 3 can be opened.

In the present invention, the rotating piece of the key is provided with convex and concave edges. The rotating piece 6 of the key 5 rotates in a cross-shaped angle at each rotating block in the lock body. There are at least two rotating pieces 6, and each rotating piece 6 has the same length. The length of the rotating piece 6 can also vary.

The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above. Those skilled in the industry should understand that the present invention is not limited by the above-mentioned embodiments. What are described in the above-mentioned embodiments and the description only illustrate the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will also have Variations and improvements are possible, which fall within the scope of the claimed invention. The claimed scope of the present invention is defined by the appended claims and their equivalents.
