Embodiment 1

[0030] A variable combination encryption mechanical key with a key-shaped structure of the present invention, comprising a screw 4 connected in series with a key head 1, a key-shaped part 2 and an intermediate rod 3 on the outer periphery, and a key rod 6 connected in series on the outer periphery and can be opposite to the described The nut rod 5 that the key rod 6 rotates, and the key handle 9 that the roller 8 is installed; wherein the screw 4 is threadedly connected with the nut rod 5, the nut rod 5 is fixedly connected with the roller 8, and the key rod 6, one end is fixedly connected to the key handle 9, and the other end is connected to the middle rod 3; when the roller 8 is manually rotated, the nut rod 5 fixedly connected to it rotates accordingly, and the screw 4 gradually moves toward the The direction of the nut rod 5 is tightened so that the head and tail structures of the spoon head 1, the spoon-shaped part 2 and the middle rod 3 connected in series on the outer p...

Embodiment 2

[0032] The key-shaped structure is composed of five independent key-shaped parts penetrated by screws, which can be detachably combined; the key-shaped parts are arranged and combined to form a key tooth shape that can be inserted into the lock cylinder of the lock and matched with it to unlock the lock. The screw has a screw head limited to the spoon-shaped part, a screw shaft passing through the spoon-shaped part, and a screw tail fixedly connected with the key body. The cross-section of the screw shaft is a circular polished rod structure, and the joint parts of two adjacent spoon-shaped parts that run through its periphery are respectively provided with socket structures for mutual positioning, anti-rotation and torque transmission. The parts respectively have anti-rotation structures positioned in cooperation with their adjacent parts. The socket structure between the spoon-shaped parts refers to the matching design of bosses or recesses on the joint surfaces of two adjac...

Embodiment 3

[0034] The key-shaped structure is composed of six independent key-shaped parts penetrated by screws, which can be detachably assembled; the key-shaped parts are arranged and combined to form a key tooth shape that can be inserted into the lock cylinder of the lock and matched with it to unlock the lock. The screw has a screw head limited to the spoon-shaped part, a screw shaft passing through the spoon-shaped part, and a screw tail fixedly connected with the key body. The cross-section of the rod section where the screw shank cooperates with the spoon is designed as a non-circular special-shaped structure, and the spoon-shaped part that runs through its periphery has a matching structure with the screw shank to achieve mutual positioning and anti-rotation. Perforated structure for rotation and torque transmission. The design form of the spoon-shaped part is a spoon-shaped part whose height varies as a step. The spoon-shaped parts whose heights vary in steps adopt plate-shape...

Abstract

The invention relates to a key shape structure, in particular to the key shape structure applied to mechanical keys, and belongs to the technical field of key shape structures. The key shape structure is characterized in that the a plurality of independent key shape parts where a screw penetrates through are detachably combined to form the key shape structure, and a key thread form which can be inserted into a lock cylinder and matched with the lock cylinder to conduct unlocking is formed after the key shape parts are arrayed and combined. According to the key shape structure, thievery prevention and duplication prevention of a key are achieved, and the unique advantages are achieved in the various important fields such as the safe case field, the military area field, the bank field, the domestic intelligent anti-theft lock field and other fields where security protection is needed. The problems which are caused by electronic circuit device software to electronic keys can not occur, the key shape structure has the advantage of being unique, a traditional mechanical key machining process is changed, energy is saved, consumption is lowered, and the application prospects are wide.

Description

[0001] technical field [0002] The invention relates to a key structure, in particular to a key structure applied to a mechanical key, and belongs to the technical field of key structures. Background technique [0003] At present, with the improvement of people's living standards, higher and higher requirements are put forward for home safety, and the corresponding anti-theft door locks are also constantly advancing towards the goal of higher anti-theft; The anti-theft performance puts forward higher requirements. In recent years, many lock manufacturers have developed products with high anti-technical opening capabilities, such as mechanical anti-theft locks and electronic smart anti-theft locks, but all mechanical anti-theft locks are opened by mechanical keys, and almost all electronic smart anti-theft locks A set of mechanical keys for emergency opening must be spared, which brings a new problem. If the mechanical key is stolen or duplicated, theft cases will still o...
