The specific embodiment

With reference to accompanying drawing, Reference numeral 1 refers generally to break-in resistant lock.

Lockset 1 comprises the box-like body 2 of holding a plurality of forming boards 3, forming board 3 is provided with a corresponding surperficial appropriate section (not illustrating in the drawings) that is suitable for being engaged in separably driving lever 4, driving lever 4 can translation, and support at least one at its free end 5 places can be with the locking bolt 6 of driving lever 4 withdrawals.

Especially with reference to embodiment shown in the drawings, driving lever 4 (and terminal 5) supports four locking bolts parallel to each other 6.

By the effect of key (not shown), plate 3 can be realized vertical translation, and plate 3 is designed to, and when they rise, discharges the translation of driving lever 4 and locking bolt 6, thereby realizes their withdrawal and stretch out.

At least one plate 3 comprises at least one zone 7, and the zone 7 is provided with at least one pedestal 8, and this pedestal aligns with at least one projection 9 and near at least one projection 9, the shape of this projection 9 basically with the shape complementarity of pedestal 8.

At least one plate 3 that is provided with at least one pedestal 8 can the direct pivot 10 around positive engagement to box-like body 2 be swung.

In fact, the swing between two utmost point positions that the geometry by lockset 1 structure limits is possible.In fact, this motion can move to second static topology from first layout, first layout is at least one pedestal 8 is cooperatively interacted with corresponding at least one projection 9, use external force to make the outside of driving lever 4 and locking bolt 6 withdrawals invade result's (situation shown in Figure 4) of incident as attempting, in second static topology, pedestal 8 separates plate 3 free shift with projection 9, therefore, driving lever 4 extended and withdrawals (situation shown in Figure 2).

In first layout (situation shown in Figure 4), should be noted that plate 3 is impossible translation, so driving lever 4 is locked: this situation has been guaranteed the protection to the intrusion incident as the picking lock.

In fact, by a proper tools, the robber keeps driving lever 4 stressed, forces its withdrawal, relies on second instrument, and stacked plate 3 is risen one by one until driving lever 4 discharged fully, so its translation backward freely, make locking bolt 6 withdrawals.

By the locking that the stable cooperation of the pedestal 8 of part 7 and fixed lobe 9 (externally take place under Zuo Yong the situation, make driving lever 4 be subjected to pulling force in the direction of its withdrawal) produces at least one plate 3, make plate 3 in that invade via second also can not the generation translation under the instrumental purpose.So in fact, no matter when external force makes locking bolt 6 (and therefore making driving lever 4) withdrawal, the translation of plate 3 all is impossible, because can only impel projection 9 pedestals 8 relative with it to engage like this.

Plate 3 comprises at least one gathering sill 11 separately, and this gathering sill holds the pivot 10 of positive engagement to box-like body 2: in fact, pivot 10 constitutes the center of rotation of each plate 3 when the intrusion incident of at every turn attempting with external force withdrawal driving lever 4 and locking bolt 6.
