And the key is movably inserted into the key hole and is provided with a plurality of marble grooves. According to the invention, the plurality of marbles and marbles which are arranged and distributed together play a locking role, and the lock cylinder is set to be opened only by rotating and pushing, so that the anti-technical unlocking capability is extremely high, and the safety is high.

A lock core includes a shell, a plug within and rotatable relative to the shell between a first position and a second position about a longitudinal axis of the plug, and a lock. The lock has a first locked position preventing rotation of the plug relative to the shell, an unlocked position allowing rotation of the plug relative to the shell and a second locked position different from the first locked position preventing rotation of the plug relative to the shell. The lock is moveable from the first locked position preventing rotation of the plug relative to the shell to the unlocked position with a first movement of the lock, the first movement having a vector component along the longitudinal axis of the plug and a vector component along an axis transverse to the longitudinal axis of the plug

The present invention addresses the problem of providing a key that allows key number information to be changed or added and that allows key information to be easily read. A key 1 has a key body 2 and key information 3 displayed on the surface of the key body 2. The key information 3 is a two-dimensional code 30 that can be read by a reading device. The two-dimensional code 30 is preferably displayed on a flat surface of the key body. The key body 2 has a tip end 2a that can be inserted into a lock and a base end 2b on the side opposite the tip end 2a; and the two-dimensional code 30 is preferably located on the base end 2b side and displayed on a flat base end surface 23 that extends in a direction Z that intersects the direction connecting the tip end 2a and the base end 2b.

The utility model discloses a safety lock cylinder which comprises an inner cylinder, a cylinder sleeve and at least two lock wheels. The inner core is sleeved in the core sleeve and can rotate in the core sleeve for unlocking; the lock wheels are arranged in the inner core in parallel in a sleeved mode and can rotate in the inner core for unlocking. According to the key, the cross section of one end, extending into the lock cylinder, of the key is arc-shaped so as to correspond to the arc-shaped key hole of the lock wheel; and lock teeth corresponding to the rotation angle of the unlocking opening of the lock wheel are arranged on the opening edge of one side, corresponding to the unlocking opening of the lock wheel, of one end, extending into the lock cylinder, of the key. The anti-theft lock is good in anti-theft performance and simple in structure.

A locking device for connecting two assemblies to one another includes a first locking part which is associated with a first one of the assemblies and a housing part and two slots each having at least one first engagement protrusion, wherein at least one of the slots includes an adjustment element which can be adjusted relative to the housing part. The locking device also includes a second locking part which is associated with a second one of the assemblies and comprises two engagement elements each with at least one second engagement protrusion. The adjustment element is arranged on the housing part of the first locking part so as to be adjustable between a first position and a second position.

The present invention discloses a blade anti-theft lock core, including a lock shell, a lock core and a side column. The lock core is provided with a plurality of lock core blade straight-through grooves, and each lock core blade straight-through groove is provided with an outer blade, an inner blade and a blade spring. The outer blade includes an upper outer blade and a lower outer blade, and the inner blade includes an upper inner blade and a lower inner blade. The blade spring includes an upper blade spring and a lower blade spring. The upper outer blade, the lower inner blade and the upper blade spring form a first blade group, and the lower outer blade, the upper inner blade and the lower blade spring form a second blade group. The first blade group and the second blade group form a whole in the lock core blade straight-through groove. The above technical scheme solves the defect that three blades or four blades share one spring in the prior art, and some blades are in a floating state without force when unlocking. The structural design is reasonable, the technical opening difficulty is increased, the key quantity is increased, the mutual opening rate is reduced, and it is safe, reliable and practical.

A key device (10) includes a generally elongate shaft portion (12), and at least one magnetic key combination element (20) disposed in the shaft portion (12), which is rotatable about a rotation axis (22).

The utility model belongs to the technical field of key protection shells, and particularly relates to an anti-falling type automobile intelligent key shell which comprises a protection sleeve and a key area on the protection sleeve, a square groove is formed in one side of the protection sleeve, a protection pad is fixedly connected to the protection sleeve, a female buckle is installed at one end of the protection pad, and a male buckle is installed at the other end of the protection pad. A male buckle is fixedly installed on the protective sleeve, and the protective pad covers the square groove through the female buckle and the male buckle. According to the automobile intelligent key protection sleeve, the protection pad is arranged to protect a spare key, the spare key on one side of an automobile intelligent key is located in the square groove, then the female buckle is pulled to be separated from the male buckle, shielding of the protection pad on the square groove is removed, the spare key is exposed, and then the spare key is popped out of the protection sleeve through the pressing head to be used. After use, the spare key is taken back, the protective pad shields the spare key through connection of the female buckle and the male buckle, operation is easy and convenient, the spare key is prevented from being abraded and collided, and meanwhile the overall attractiveness is improved.
