Abstract
The utility model discloses a mechanical joint control safe, which solves the problem that the past safe having a door lock or a coded lock for safety is easily destroyed; a door bar machine control device is added at the back side of the inner door, and the device is provided with a bayonet lock mechanism; a parallel control mechanism is composed of a spring spindle device and a gearbox, which reinforces the prevention of abnormal open door technology knack and prevents the corrosion breaking door by corrosive acid liquid medicine; the breaking door difficulty of anti-violence, anti-drilling, anti-prying, anti-chiseling etc. is reinforced; the utility model is suitable for preserving money.
Description
The utility model relates to the improvement invention of strongbox.
In the prior art, strongbox only is provided with door lock and coded lock insurance, and the law-breaker can use tool for destroying or skill wood tricks of the trade to open password; Perhaps use strong acid class chemical medicinal liquid to aim at that key pitting corrosion lock core is weak opens security door behind the part in addition, perhaps adopt violent means, prize, pound, brill etc. opened security door.
In view of the defective that prior art exists, the utility model aims to provide a kind of machinery control inside door bolt opening device, reaches the effect that prevents deciphering, forces open the door lock, the purpose of reducing the loss.
The utility model is finished by following scheme, a kind of mechanical joint control strongbox comprises casing, external door, inside door, external door is provided with door lock, coded lock, spanner, door latch apparatus, and inside door is provided with coded lock, spanner, bolt controlling organization, and described bolt controlling organization is; At the back side of inside door, on described wrench gear, be hinged with tooth bar, be provided with long slot bore and the movable coupling of the pin on the door in the middle of this tooth bar, play the guide and limit effect; One of tooth bar is fixedly hinged with straight-bar, and the straight-bar epimere is pintle hook lock fixedly, and pintle hook lock and coded lock are complementary; The upper end of straight-bar and lower end and bolt are movably hinged, and bolt has door frame, and bolt can move back and forth, and can control inside door and open or close.Open coded lock, pull spanner,, remove bolt through tooth bar, straight-bar.
The bolt controlling organization has clamping pin mechanism, spring spindle device and gear-box and forms.This clamping pin mechanism is with the pin frame bayonet lock of being with spring to be housed in interior rotating shaft side behind the door, and bayonet lock can be controlled inside door and open or close.Bayonet lock is provided with the hook groove, and the hook that is provided with the pin hook is complementary, and one on pin hook is hinged with tooth bar, and the taper pin groove is offered at pin hook middle part, with the movable coupling of the interior pin that is provided with, plays spacing guide effect behind the door.Hook on the pin hook hooks the hook groove on the bayonet lock, keeps in touch.If open coded lock, the switching spanner hooks, spurs bolt through tooth bar, pin hook, just can open inside door.
Gear-box is located at the doorframe top or the below of inside door and external door, the rotating shaft of external door is affixed with the driving gear shaft concentric or tighten up and cooperate, secondary gear on driving gear and the secondary gear axle is complementary, drive secondary gear, secondary gear and tertiary gear are complementary, and drive tertiary gear, are fixed with rotating disk on the tertiary gear axle, rotating disk is provided with arc groove, and a termination of the push rod in arc groove and the spring spindle device is complementary.
The spring spindle device comprises push rod, spring, adjusting mother Luo, and another termination of push rod and the hole that bayonet lock is provided with are complementary, the motion of control bayonet lock.When opening external door, external door is rotated, when forwarding certain angle to together with rotating shaft, through driving gear, secondary gear, tertiary gear, to dial rotation and make arc groove on the rotating disk and dell and push rod at once, push rod is the top upper groove under resilient force, bayonet lock is thrown off in the push rod other end, under the situation that coded lock is opened, pull spanner, draw back bayonet lock and can open inside door.If the position that external door is opened is not right,, then can not open inside door because of the dell of the arc groove on the rotating disk is not corresponding with push rod.For this reason, realize outer gate control inside door.
The utility model has solved existing disclosed strongbox and has only established door lock and coded lock underinsurance, has set up the interlock of bolt controlling organization at the back side of inside door, has strengthened the tricks of the trade that prevent the improper technology of opening the door; The 2nd, machine control unit is set up at the inside door bolt back side, prevents that effectively strong acid liquid medicine corrosion from forcing open the door; The 3rd, strengthened the anti-violence difficulty of forcing open the door, door is difficult to open with means such as sled, brill, cutters.Also set up clamping pin mechanism, gear-box and spring spindle device, the external person of forcing open the door has been established dark together control safeties, improved safety factor greatly at the inside door back side.
