Description
A kind of anti-drilling, anti-pound, prevent cutter, anti-grip coded lock.Belong to the coded lock field.
Three-chip type safety cabinet coded lock is that two passive locking plates string together, and couple together by cottor pin and digital dial axis, and are fixedly mounted on the safety cabinet door leaf by fixed disk, an active of spring locking plate at present.This coded lock is because between fixed disk and second the passive locking plate, only be safety cabinet door leaf one plate every, stealer with the way of brill, after punching, detectable locking plate opening is stirred passive locking plate successively, initiatively locking plate, the cabinet door is opened, also can be directly with cut a hole, pound, the way of the digital dial of draw vice, locking plate is offed normal, lose the effect of pinning the bolt frame, therefore this coded lock can not be anti-drilling, cut a hole, pound, can not anti-grip.
The purpose of this utility model provides a kind of improved coded lock, and this coded lock can anti-drilling, anti-ly be cut a hole, anti-grip.
Solution of the present utility model is on the basis of common three-chip type coded lock, increases a slice open slot and second synchronous locking plate that passive locking plate open slot staggers.Active locking plate, passive locking plate, synchronous locking plate cover box with one and cover, and use the instrument steel plate reinforcement at the bottom of the cover box, and the metal ring of an opening is set between cover lid and the active locking plate, cover at the bottom of the box and the welding of safety cabinet door leaf.
The utility model is owing to increased the synchronous locking plate of a slice, used the instrument steel plate reinforcement again at the bottom of the cover box, strengthened the difficulty that stealer bores, promptly use special way to open the hole, because cover box and the shielding of locking plate synchronously, make stealer be difficult to survey passive locking plate, the open slot of active locking plate, because the metal garden of cover box and opening ring has the effect of holding locking plate, the stealer way of drawing, clamp, cut a hole, pounding digital dial, be difficult to make locking plate to be offed normal, thereby reached anti-drilling, anti-cutter, anti-ly pound, the purpose of anti-grip.
Accompanying drawing is the utility model structural representation.
The active locking plate (1) and the first passive locking plate (3), the first passive locking plate (3) flexibly connects with dialling the nail (2) of shipping and reselling on another market with the second passive locking plate (6), the second passive locking plate (6) is fixedlyed connected with dialling ship and resell on another market (7) with synchronous locking plate (8), locked spacer (14 is arranged between the locking plate, 18), between locking plate (8) and the cover box plate (13) spring (11) is being arranged synchronously, cover box plate (13) is reinforced with same tool steel plate (12) and is welded with safety cabinet door leaf (4), fixed disk (9), spring (11), locking plate (1,3,6,8) be enclosed within on digital disk (10) axis, and lock with cottor pin (17), the cover box is a garden shape, and use bolt, nut, pad (19,20,21) be connected with cover lid (15), (16) external diameter and locking plate external diameter basically identical are encircled in opening metal garden, and weld with the cover lid.
The utility model adopts in force
The thin same tool steel plate of 0.5mm, because the bolt frame adopts the band steel of 4mm,, being slightly larger than bolt frame band steel thickness so the A/F of cover box limit (5) and opening metal garden ring (16) adopts 5mm, the cover box is used
The steel plate of 3mm makes, stud weld on cover box limit, and with nut with cover lid and be connected, do not change the original code locking and make technology.
