Description

Lockset opening and closing device on a kind of national treasury door

Technical field

The utility model relates to the bank vault security fields, particularly relates to the lockset opening and closing device on a kind of national treasury door.

Background technology

In recent years, financial sector recurred important cases.Data shows that the national treasury larceny case is interior theft case part more than 90%, promptly defalcates, colludes from both within and without and coerced by ruffian's violence and open Ku Men, that is use the crime of opening the door of key and password.

At present worldwide, what generally use on the national treasury door is the coded lock and the special-purpose lock of double key of frame for movement, mainly is the consideration aspect reliability; And the IC-card, the biological gate inhibition's intelligent product degree height that occurred in recent years, but owing on reliability, there is deficiency, on the national treasury door high to reliability requirement, also be not suitable for using, mainly be used on the isolating door of national treasury.And the potential safety hazard of national treasury just because of day hold-open door key and password illegally utilized, cause the national treasury door to be opened the warehouse-in crime by the offender, the special-purpose control system that can preventing exactly of needing most like this illegally opened the door also will satisfy requirement intelligent and that reliability has concurrently simultaneously technically.

The utility model content

The purpose of this utility model provides the lockset opening and closing device on a kind of national treasury door, mainly is to guarantee under the situation that lockset can not normally open and close, and can guarantee to realize that by this device lockset opens and closes.

The technical scheme that adopts is:

Lockset opening and closing device on a kind of national treasury door comprises shift fork, handwheel and mechanical code lock.

Its technical essential is:

The shift fork upper end is provided with allocating slot, and the position of setting at the middle part of shift fork is provided with through hole, and the through hole inward flange is provided with entad projection, is provided with the retaining pin in the lower end of shift fork.

Handwheel is made up of handle and driving lever, fixedlys connected with handle in the driving lever upper end, and the driving lever lower end is provided with the groove that is complementary with described entad projection.

The driving lever of handwheel passes the shift fork through hole, and entad projection and groove match.The handle of handwheel is arranged on the national treasury door external body shop front.Mechanical code lock is arranged on shift fork lower end one side, the prior position of setting, and mechanical code lock is commercially available known product, the dial of mechanical code lock is positioned on the national treasury door external body shop front.After the gap on whole coded lock discs of mechanical code lock overlapped in position, the lower end retaining pin of shift fork can enter in the gap.

Its operating principle is:

When handwheel during to right rotation, the upper end allocating slot moves right, and the dead bolt of the lockset installed in advance can be transferred to, and makes lockset be in locking states; When handwheel during to anticlockwise, fail at the relevant position gap all when overlapping when the coded lock disc of mechanical code lock, the retaining pin is stopped by the coded lock disc, and it is limited to move right, cause the upper end allocating slot not to be moved to the left, thereby can not dial back the dead bolt of the lockset that installing is good in advance; Dial when the rotary machine coded lock, make the gap of whole coded lock discs overlap the relevant position, rotation hand wheel left, the retaining pin of shift fork lower end enters in the overlapping gap on the coded lock disc, shift fork top is moved to the left, the dead bolt of the lockset that installing in advance is good is dialled in the lock body, and lockset is in opening.

Its advantage is: when the daily unlocking system of lockset lost efficacy, this device can be controlled the switching of lockset reliably, and guaranteed can not influence operate as normal and safety.The utility model overall structure is simple and reliable, and long service life has extremely strong specific aim and practicality, is the special lockset control device for the customization of banking national treasury door.

The specific embodiment

Lockset opening and closing device on a kind of national treasury door comprises shift fork 6, handwheel 2 and mechanical code lock 5.

Shift fork 6 upper ends are provided with allocating slot 1, and the position of setting at the middle part of shift fork 6 is provided with through hole 7, and through hole 7 inward flanges are provided with entad projection 8, are provided with retaining pin 9 in the lower end of shift fork 6.

Handwheel 2 is made up of handle 3 and driving lever 4, fixedlys connected with handle 3 in driving lever 4 upper ends, and driving lever 4 lower ends are provided with the groove 10 that is complementary with described entad projection 8.

The driving lever 4 of handwheel 2 passes shift fork through hole 7, and entad projection 8 and groove 10 match.The handle 3 of handwheel 2 is arranged on the national treasury door external body shop front.Mechanical code lock 5 is arranged on shift fork 6 lower ends one side, the prior position of setting, and mechanical code lock 5 is commercially available known product, the dial of mechanical code lock 5 is positioned on the national treasury door external body shop front.After the gap on whole coded lock discs of mechanical code lock 5 11 overlapped in position, the lower end retaining pin 9 of shift fork 6 can enter in the gap 11.
