Abstract
The utility model discloses an anti-theft lock cylinder with an improved structure. The anti-theft lock cylinder comprises a cylindrical lock cylinder body, an unlocking key and a blade, wherein a plurality of blade grooves which are parallel with one another are formed in the lock cylinder body; a key channel is parallel with or coincident with the axis of the lock cylinder body; the anti-theft lock cylinder is characterized in that the key channel is formed by cutting part of the volume of a hollow cylinder through one cutting plane parallel with or coincident with the axis of the hollow cylinder or two cutting planes which are intersected with each other and are parallel with or coincident with the axis of the hollow cylinder. As the key channel has a complex structure, and a correspondingly key is difficult to imitate, so that the anti-theft performance of the anti-theft lock cylinder is improved.
Description
Technical field
The utility model relates to a kind of anti-theft lock core that improves structure.
Background technology
Anti-theft lock core, its structure should be consistent with the key of its coupling.In prior art, the cross section of the key channel of common lock core body is flat structure.Corresponding key embryo is also platypelloid type with it, lock core and key thereof simple in structure, and key is easily imitated, and the performance of theftproof lock reduces greatly.
Utility model content
The utility model is for overcoming deficiency of the prior art, and the utility model provides a kind of anti-theft lock core that improves structure, to improve the theftproof performance of lockset.
The anti-theft lock core of improvement structure of the present utility model, comprise lock core body, unlock key, the blade of cylindrical shape, on lock core body, offer the blade groove that several are arranged in parallel, key channel is parallel to or coincides with the axis of lock core body, described key channel is the cutting plane that is parallel to or coincides with hollow circuit cylinder body axis by, or mutually crossing and parallel or coincide with the cutting plane of hollow circuit cylinder body axis, the part of remainder after cutting hollow circular cylinder partial volume by two.Due to the complex structure of key channel, the imitated difficulty of corresponding key, therefore the theftproof performance of anti-theft lock core improves.
As improvement.The anti-theft lock core of improvement structure of the present utility model, offers a guide groove that connects lock core body outer face at the external surface of lock core body along the direction of lock core shaft; In lock core body footpath upwards, this guide groove and key channel connect, described key channel taking described guide groove as axis of symmetry symmetrical.Owing to increasing guide groove, adapt to the continuous operation of the cutter of processing lock core, improve production efficiency.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model lock core and this lock key thereof.
Fig. 2 is the structural representation of the utility model lock core body.
Fig. 3～Figure 10 is respectively the cross sectional representation of the lock core body of the first～eight embodiment.
Detailed description of the invention
Further illustrate embodiment of the present utility model below in conjunction with accompanying drawing.
Referring to Fig. 1 and Fig. 2.Anti-theft lock core of the present utility model, comprises the parts such as lock core body 1, blade, unlock key, and the parts such as its Leaf, unlock key do not draw in the drawings.Lock core body 1 is cylinder type, and several blade grooves that are arranged in parallel are perpendicular to the axis of lock core body.Blade is placed in blade groove.While unblanking, key inserts from the outer face of lock core body 1 key channel 2 that is arranged in lock core body 1.Key channel 2 is parallel to the axis of lock core body 1 or the dead in line with lock core body 1.Key channel 2 connects the outer face of key channel 2.
Fig. 3 is first embodiment of the present utility model.In this embodiment, key channel 2 be by two mutually intersect and all with the cutting plane of hollow circular cylinder dead in line, cut the part of remainder after hollow circular cylinder partial volume.In the utility model, aforesaid cutting plane can also be two planes that mutually intersect, and one of them plane parallel is in the axis of hollow circular cylinder, the dead in line of another plane and hollow circular cylinder.In addition, aforesaid cutting plane is also can one parallel or coincide with the plane of hollow circuit cylinder body axis.
Fig. 4, Fig. 5, Fig. 6 be respectively of the present utility model second, third, the cross-sectional structure schematic diagram of lock core body in the 4th embodiment.The difference of these four embodiment and first embodiment is: the inner wall shape of hollow circular cylinder is different.The inwall of the hollow circular cylinder of the utility model to key body does not limit, and can be any shape.At second, third, in the 4th, the 5th embodiment, described cutting plane can also be only the plane in a parallel hollow cylinder axle center; Or two cutting planes that are parallel to respectively hollow circuit cylinder body axis; Can also be another with parallel with hollow circuit cylinder body axis respectively and crossing cutting plane between two, the part of remainder after cutting hollow circular cylinder.
Fig. 7, Fig. 8, Fig. 9, Figure 10 are respectively the 5th to the 8th embodiment of the present utility model.Be with first to fourth embodiment difference: the external surface at lock core body is offered a guide groove that connects lock core body outer face along the direction of lock core shaft; In lock core body footpath upwards, this guide groove and key channel connect, described key channel taking described guide groove as axis of symmetry symmetrical.
Due to the complex structure of key channel 2, the imitated difficulty of corresponding key, therefore the theftproof performance of anti-theft lock core improves.Owing to increasing guide groove, adapt to the continuous operation of the cutter of processing lock core, improve production efficiency.
