Description

Safe

The utility model relates to the improvement invention of strongbox.

Existing known strongbox only is provided with security door one, but offender's operation technique tricks of the trade, and using snatches password opens security door; Perhaps use strong acid class chemical medicinal liquid to aim at the key hole, corrosion is weak opens security door behind the part in addition; Perhaps adopt violent means, prize, pound, cutter etc. is opened security door.

In view of the deficiency of existing known technology, the purpose of this utility model is to prevent strong acid liquid medicine eject lock keyhole means, strengthens uprising force intensity, sets up the second road technology barrier.

Further purpose of the present utility model provides the follow-up dark control insurance means behind the second road security door coded lock, and sets up dark control mechanism.

The uprising force intensity of security door that the 3rd purpose of the present utility model is further enforced safe.

The purpose of this utility model is finished by following scheme, sets up second road security door, the i.e. inside door in original existing security door again.Do not establish bright lock on the inside door, establish coded lock, spanner, door bolt mechanism.

Door bolt mechanism is the back side at inside door.Various ways is arranged, simply have a cross bar to make bolt, hinged spanner, the switching spanner drives bolt and moves back and forth.Also can be, be hinged with cross bar on the spanner, be fixed with pintle hook lock on the cross bar, pintle hook lock and coded lock are complementary; One slotted eye and the movable coupling of the pin on the door are arranged in the middle of the cross bar, play the guide and limit effect; One of cross bar the higher authorities and the bolt with following and following straight-bar of upper straight rod is hinged, can rotate; Bolt has door frame, and bolt can move back and forth, and can control inside door and open or close.The stage casing of upper straight rod and following straight-bar is contained in back behind the door with the pin activity, can rotate.Open coded lock, pull spanner and rotate,, remove bolt through cross bar, straight-bar.

Door bolt mechanism also has control device, and this device is made up of clamping pin mechanism, spring spindle device and gear-box.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 cross bar, and pin hook middle part offers the taper pin groove, with the movable coupling of the interior pin that is provided with, plays spacing guide effect behind the door.Also be provided with spring between pin hook and the channel bar, make the pop-up of pin hook, the hook on the maintenance pin hook hooks the hook groove on the bayonet lock, keeps in touch.If open coded lock, the switching spanner hooks, spurs door bolt through cross bar, pin hook, just can open inside door.

Gear-box is established the doorframe top or the below that can be located at inside 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 the arc length connected in star, and a termination of the push rod in arc length connected in star and the spring spindle device is complementary.

The spring spindle device comprises push rod, spring, upper support piece, lower support piece, 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 the dell of the arc length groove on the rotating disk 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, the switching spanner draws back bayonet lock and can open inside door.If the angle opened of external door is not right, because of the dell of the arc length groove on the rotating disk not with the push rod correspondence position, then can not open inside door.For this reason, realize outer gate control inside door in the dark.

In the periphery of inside door, external door, all can be welded with band iron, also can be provided with badge, strengthen firm, intensity at the rotating shaft side back side of inside door.

The utility model has solved existing known strongbox simple gate underinsurance, has set up the second road barrier, has increased the improper technical difficulty of opening the door; The 2nd, inside door is not established bright lock, can prevent that strong acid liquid medicine corrosion from forcing open the door; The 3rd, strengthen the violence difficulty of forcing open the door, door be difficult to prize, pound, means such as cutter open.

If set up the bolt control device, clamping pin mechanism, gear-box and spring spindle device more increase the anti-technology performance of forcing open the door, and the external person of forcing open the door has been established dark together control safeties, have strengthened safety factor greatly.

If in inside and outside door periphery, add band iron, badge again, more increase firmness, strengthen preventing the violence performance.
