Description

The Anti-theft machinery lock core

Technical field

The utility model relates to mechanical billiard lockset field, is specially a kind of Anti-theft machinery lock core.

Background technology

Lock core is the major part that the control lock is opened, and is the heart of lockset, refers to the supporting core that can rotate and drive the locking bolt motion of key.The major function of lock core is to transmit torsion by head, thereby drives the miscellaneous part of lock, reaches and unblanks and locking.The lock core head construction of padlock, drawer-lock, door lock and bicycle lock is not quite similar, and the mode of transmitting torsion is also different, but effect is the same.

Existing mechanical billiard lockset is because simple in structure, and is easy to use and be widely used.But the lock core rotor of this class mechanical billiard lockset is an overall structure, therefore, as long as find suitable instrument, take plug body as the strong point, just can opportunity is provided for some lawless persons than being easier to open lockset, causes very large potential safety hazard.Present lock core structure is generally the mechanical lock of spring marble, and supporting key is easily copied, and the unpacking password of normal key type strongbox is easily forgotten.

The utility model content

The technical problem that the utility model solves is to provide a kind of Anti-theft machinery lock core, to solve the problem that proposes in the above-mentioned background technology.

The technical problem that the utility model solves realizes by the following technical solutions:

The Anti-theft machinery lock core, comprise key and lock body, described key is the same with existing key, be plane key or cross key, described key comprises polylith revolving fragment and main shaft, and described revolving fragment is fixed on the main shaft by bearing, described lock body is provided with key insertion hole, be provided with cross type spill spin block with the revolving fragment same number along the inner key insertion hole of lock body, be equipped with pellet on above-mentioned each spill spin block, described pellet is provided with spring; Key is rotated after inserting keyhole, and described key becomes the plane along inner each spill spin block of lock body by the Plane Rotation across or by cross-shaped rotary, and spill spin block jack-up pellet after rotation is finished just can be opened lock core.

Further, the revolving fragment of described key is provided with the convex-concave limit.

Further, the revolving fragment of described key anglec of rotation between each spill spin block in lock body is chiasma type.

Further, described revolving fragment is minimum to be 2, each revolving fragment equal in length.

Further, described revolving fragment is uneven in length.

Beneficial effect:

The utility model is simple in structure, and is easy to use, and anti-theft effect is good, safe and reliable; Can be used for plug-in, the in-built theftproof lock of various mechanical types.

Description of drawings

Fig. 1 is the structural representation of the utility model key;

Fig. 2 is structural representation of the present utility model;

Fig. 3 is the lateral view of Fig. 2.

The specific embodiment

In order to make realization technological means of the present utility model, creation characteristic, to reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

Shown in Fig. 1～3, the Anti-theft machinery lock core, comprise key 5 and lock body 2, described key 5 is the same with existing key, be plane key or cross key, described key 5 comprises polylith revolving fragment 6 and main shaft 7, described revolving fragment 6 is fixed on the main shaft 7 by bearing, described lock body 2 is provided with key insertion hole, be provided with cross type spill spin block 3 with revolving fragment 6 same number along lock body 2 inner key insertion holes, be equipped with pellet 4 on above-mentioned each spill spin block 3, described pellet 4 is provided with spring 1; Be rotated after key 5 inserts keyhole, described key 5 becomes the plane along inner each spill spin block of lock body by the Plane Rotation across or by cross-shaped rotary, and spill spin block jack-up pellet 4 after rotation is finished just can be opened lock core.

In the utility model, the revolving fragment of described key is provided with the convex-concave limit.The angle of the revolving fragment 6 of described key 5 each spill spin block rotation in lock body is chiasma type.Described revolving fragment 6 is minimum to be two, each revolving fragment 6 equal in length.Described revolving fragment 6 length also can not wait.

Above demonstration and described basic principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the manual just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
