A kind of ruggedized construction of safe lock
Technical field
This utility model belongs to safe lock, is specifically related to the ruggedized construction of a kind of safe lock.
Background technology
Safety cabinet is incorporated business, and all trades and professions and individual deposit the safety cabinet of valuables and wealth, at present the product of existing multiple different structure, no matter that a kind of safety cabinet, has it not enough.The complicated structure having in these safety cabinets, that have in-convenience in use, what have is more easily damaged, and theftproof performance is poor, has the safety cabinet structure of 90% to be easily destroyed on the market.
Such as Fig. 1, shown in Fig. 2, most safe lock is all prevent safety cabinet to be opened by driving plectrum 4 to withstand the dead bolt 5 coordinated with cabinet 1 in the lockout condition by the lock core 9 being located on cabinet door 2 on the market, if plectrum 4 withstands dead bolt 5, it is located at the rotating disk 12 on cabinet door 2 and cannot be driven the mated condition of dead bolt 5 motion disengaging and the cabinet 1 that be located on connecting rod 6 by rotation gear 7, connecting rod 6 also cannot be matched with the tilted slotted hole 1101 on the tilted slotted hole 601 in upper lock rod 8 and lower locking bar 11 respectively by pin 10 and drive upper and lower locking bar 8 simultaneously, dead bolt 5 motion on 11 departs from the mated condition with cabinet 1, safety cabinet is in blocking, otherwise, rotate rotating disk 12 and can open safety cabinet.The safety cabinet of this employing plectrum structure; often lock core 9 is not had protective effect; lock core 9 is only be fixed on cabinet door 2 by one block of fixing plate 3; significant portion is exposed to cabinet portion outdoors, in time being subject to the violence damage in the external world, as long as fixing plate 3 slightly loosens or directly drops; the cooperation of dead bolt 5 is occurred loosening or bias phenomenon by plectrum 4; as long as so twisting rotating disk 12, safe door 2 is opened naturally, and whole safety cabinet loses anti-theft feature.Therefore, it is necessary to develop the better safe lock of better theftproof performance.
Summary of the invention
The purpose of this utility model is in that the defect for prior art, it is provided that a kind of rational in infrastructure, the ruggedized construction of the better safe lock of theftproof performance.
The technical scheme realizing the employing of this utility model purpose is as follows:
The ruggedized construction of the safe lock that this utility model provides, including cabinet, it is located at the cabinet door on cabinet, it is located at the rotating lock core on cabinet door and the dead bolt coordinated with described cabinet, described cabinet door is fixed with the lock pin protecting equipment wrapped up by the afterbody of described lock core, described lock pin protecting equipment is provided with and is connected, with described dead bolt, the locking bar that can seesaw, the cylinder-shaped link being connected on described lock core or with lock core afterbody is provided with the first groove of the circular arc matched with locking bar external diameter, described locking bar is provided with the second groove of the circular arc matched with described lock core or the connector external diameter that is connected with lock core afterbody.
Described lock pin protecting equipment includes the footing wrapped up by the afterbody of described lock core and covers on the protective cover outside described footing; described locking bar is connected from described footing and protective cover traverse with described dead bolt, and described protective cover and footing are fixed by screws on described cabinet door.
Beneficial effect
This utility model is owing to having installed a protection device additional at lock core afterbody, and this device can firmly withstand lock core tail end, it is prevented that the external world inwardly beats by force, and lock core afterbody contacts with protection device, so cannot destroy.Lock core is under the effect of protection device, and lock core swings and also can be firmly fixed.Protection device also can ensure that locking bar is constantly in horizontal level, can reduce the fit clearance between each part.When lock core is subject to extraneous violence, lock core can withstand locking bar, and locking bar can withstand dead bolt, so greatly strengthen the intensity of lock core, improves the theftproof performance of safe lock.
The technical solution of the utility model is further illustrated below in conjunction with accompanying drawing.

Detailed description of the invention
See Fig. 3 to Fig. 8; the ruggedized construction of the safe lock that this utility model provides; including cabinet 1, the cabinet door 2 being located on cabinet 1, the rotating lock core 9 being located on cabinet door 2 and the dead bolt 5 that coordinates with described cabinet 1, the back side of described cabinet door 2 is fixed with the lock pin protecting equipment 13 wrapped up by the afterbody of described lock core 9;Footing 1302 that described lock pin protecting equipment 13 includes wrapping up the afterbody of described lock core 9 and cover on the protective cover 1301 outside described footing 1302, described protective cover 1301 and footing 1302 are fixed on cabinet door 2 by screw 1303;Described lock pin protecting equipment 13 is provided with and is connected, with described dead bolt 5, the locking bar 14 that can seesaw, and locking bar 14 is connected from described footing 1302 and protective cover 1301 traverse with described dead bolt 5;Described lock core 9 is provided with the first groove 901 of the circular arc matched with locking bar 14 external diameter, and described locking bar 14 is provided with the second groove 1401 of the circular arc matched with described lock core 9 external diameter.
As shown in Figure 9, can also at lock core 9 afterbody connecting cylinder shape connector 902, being provided with the first groove 901 of the circular arc matched with locking bar 14 external diameter on cylinder-shaped link 902, locking bar 14 is provided with the second groove 1401 of the circular arc that connector 902 external diameter being connected with lock core 9 afterbody matches.
After seeing that Fig. 3, Fig. 4, safety cabinet install this utility model ruggedized construction, lock core 9 is enclosed in inside lock pin protecting equipment 13 completely, can fix lock core 9 in all directions.When unblanking, as shown in Figure 5, Figure 6, the first groove 901 on lock core 9 is just corresponding with the opening direction of the second groove 1401 on locking bar 14, they respectively do not affect mutually, this hour locking lever 14 can freely level seesaw, rotating disk outside by cabinet door 2 rotates gear 7 drivening rod 6 and retreats, and then drive the dead bolt 5 being connected with connecting rod 6 and dead bolt 5 motion matching on the upper and lower locking bar 8,11 of drive respectively with the tilted slotted hole 1101 on the tilted slotted hole 601 in upper lock rod 8 and lower locking bar 11 by the pin 10 on connecting rod 6 to depart from the mated condition with cabinet 1, open safety cabinet.
During locking, first rotating rotating disk makes each dead bolt 5 be in the state matched with cabinet 1, it is rotated further by lock core 90 degree, as shown in Figure 7, Figure 8, at this moment the opening direction of the first groove 901 on lock core 9 and the second groove 1401 on locking bar 14 just misplaces and is mutually perpendicular to, and lock core 9 is stuck in the second groove 1401 of locking bar 14, and locking bar 14 is spacing by lock core 9, constrain the motion in locking bar 14 horizontal direction, it is achieved blocking.
