Abstract

The utility model discloses a safe-guard door of national treasury, by the door frame, the door body, subassembly and trick lock safety mechanism such as hinge and backplate constitute. The anti-theft door is mainly characterized in that a rotary deflector rod transmission mechanism is adopted to replace a four-bar linkage, the bolt is fixedly connected with the movable plate, and the operating hand wheel is fixedly connected with the rotary deflector rod to drive the movable plate and the bolt to move along the X direction, so that the opening and closing movement of the bolt is more stable and reliable, the structure is simplified, the manufacturing cost is reduced, and the failure rate is reduced. The utility model provides a product has five-prevention characteristics, is the ideal headstock gear of national treasury and valuables insurance storehouse of present bank financial institution.

Description

The national treasury security door

The utility model relates to the door and window part, relates in particular to safe deposit or bank vault security door.

The national treasury security door is as a kind of closing device, and whether the keying flexibility and reliability of keeper is the important symbol of weighing its safe mass height.Common java standard library door on the market, the quadric chains that adopt in the keeper transmission system more, complex structure, the high and high manufacturing cost of fault rate is its major defect.Simultaneously,, resilience occurs after causing keeper to be closed, cause door leaf to be not closed completely, stay hidden danger to safety because this structure can not self-locking.Find also that in using practice the java standard library door lacks Z to constraint in opening and closing motion, easily produce Z, even form the fault that bump can't be closed to swing.

This novel product that provides is intended to adopt revolution driving lever transmission mechanism to replace traditional quadric chain, thereby makes designs simplification, and it is more steady to move, and has reduced fault rate, has satisfied higher strick precaution requirement.

The technical solution of the utility model is achieved in that

At first, in the keeper transmission system, keeper and movable plate directly are fixedly connected the cancellation quadric chain.Have special-shaped notch in the middle of the movable plate, have the revolution driving lever to be engaged with in the groove.When driving lever is driven when doing gyration by hand wheel, flywheel moment drive movable plate and keeper along X to reciprocating.So, the closure or openness of door leaf are just arranged.Secondly, one four point-supported slide guide device respectively is housed two ends up and down at keeper, it is made of sliding support and rolling bearing, and the Z that has increased keeper has improved the stability of operation to constraint.

Realize the technical solution of the utility model, 4 steel ball slip stopping means also have been installed in the both sides of keeper, guaranteed the linearity and the stationarity of keeper motion.

The disclosed national treasury security door of the utility model, comparing with the java standard library door has tangible advantage, replaces quadric chain with the revolution lever body, has not only realized original function but also simplifies the structure, and has reduced fault rate, has reduced manufacturing cost.Specifically, make Ku Men alleviate weight, open and close steadily, operate more nimble.
