The specific embodiment
The present invention is further described below in conjunction with accompanying drawing:
Fig. 1 and Fig. 2 represent the first embodiment of the present invention, and as can be seen, in the middle of this embodiment, the axis of lockhole is identical with the elongated slot 8a direction of L shaped opening.
In the present embodiment, solid shell 2 inside a lock body 1 is set, the lockhole 10 of this lock body 1 is in the inside of this solid shell 2.The opening 8 that has a turnover shape on the surface of this solid shell 2.One end 5 of lock ring 4 can be connected with the lock body 1 of solid shell 2 inside, and the other end of lock ring 4 then is connected with the other end 7 of this solid shell.Turnover shape opening 8 on the shell 2 can be L shaped or T shape (only having represented L shaped opening among the figure).The axis direction of lockhole 10 parallels with the elongated slot 8a of L shaped opening 8.
This shell 2 can be by the stainless steel manufacturing, and the profile of shell 2 can be cylindrical.Lock ring 4 is rigid construction.
Fig. 4 has represented a kind of key, corresponding to a kind of structure with theftproof lock of tamper-proof lock body that the first embodiment of the present invention provided.This key is a kind of two joint keys, form by handle portion 6 and key portion 3, handle portion 6 is orthogonal with key portion 3, the shape of this two joints key and size adapt with turnover shape opening 8, can from transferring shape opening 8, this stretch in the solid shell 2, and insert lockhole 10, to open this anti-theft lock structure.
When opening theftproof lock shown in the first embodiment of the invention, the handle portion 6 of hand-held key, elongated slot 8a key portion 3 is L shaped from this or T shape opening 8 stretches into the inside of this solid shell 2, and inserts in the lockhole 10; Then, handle portion 6 short groove directions L shaped to this or T shape 8 openings are rotated, and just can open this locked instrument.
Can be set to folding the connection between the handle portion 6 of this two joints key and the key portion 3, to be convenient for carrying.
Fig. 3 has represented the second embodiment of the present invention, and as can be seen, in the middle of this embodiment, the elongated slot 8a of the L shaped opening 8 on the axis direction of lockhole 10 and this shell 2 has certain biasing h.
In the present embodiment, solid shell 2 inside a lock body 1 is set, the lockhole 10 of this lock body 1 is in the inside of this solid shell 2.The opening 8 that has a turnover shape on the surface of this solid shell 2.One end 5 of lock ring 4 can be connected with the lock body 1 of solid shell 2 inside, and the other end of lock ring 4 then is connected with the other end 7 of this solid shell.Turnover shape opening 8 on the shell 2 can be L shaped or T shape (only having represented L shaped opening among the figure).The elongated slot 8a of the axis direction of lockhole 10 and L shaped opening 8 has certain biasing h.
This shell 2 can be by the metal material manufacturing, and the profile of shell 2 can be a square column type.Lock ring 4 also can be the chain type structure.
Fig. 5 has represented a kind of key, corresponding to a kind of structure with theftproof lock of tamper-proof lock core that the second embodiment of the present invention provided.This key is a kind of three joint keys, is made up of handle portion 6, link rod part 9 and key portion 3, and handle portion 6 is orthogonal with link rod part 9, and link rod part 9 is orthogonal with key portion 3; The shape of this three joints key and size adapt with turnover shape opening 8, can stretch in the firm housing 2 from this transfers shape opening 8, and insert lockhole 10, to open this anti-theft lock structure.
