Abstract
The utility model relates to a safe lock, particular to an anti-theft safe coded lock. The coded lock comprises a digital driver plate fixed on a safe, a dialing button which is arranged on the terminal face of a lock shaft and is corresponding to the digital driver plate, a lock blade which is arranged on the lock shaft and a shaft sleeve and a starting mechanism; more than one radial grooves are opened on the circle of the lock blade, wherein, the depth of one groove is deeper than that of other grooves. The coded lock is characterized in that a ring bite is arranged on the circle of the lock shaft, and a positioning mechanism consisting of a steel ball and a spring is installed on the shaft sleeve corresponding to the ring bite. The safe lock of the utility model is characterized by reasonable structure and high performance of anti-theft.
Description
Technical field
The utility model relates to a kind of safety cabinet lockset, particularly a kind of theft proof strongbox coded lock.
Background technology
Safety cabinet is a lot of with the kind of lockset at present, for mechanical lock, its basic functional principle is by being installed in the rotation of the digital dial on the safe door, driving the active locking plate that is installed in the door rotates, drive passive locking plate by the active locking plate and rotate, when a plurality of locking plates turned to desired location, the fore shaft on all locking plates overlapped vertically, thereby open handle by rotating, just safe door can be opened.Illegal opener is when the opening safety cabinet, when rotating digital dial, normally adopt the mode of feel or listening, just can find the fore shaft on the locking plate to overlap the position vertically, be used to install initiatively the axle of locking plate and pull up thereby open safety cabinet or will lock, safety cabinet is opened in the mode of destroying by the button handsetting of the projection on the digital dial.As Patent Office of the People's Republic of China's on May 16th, 2007 disclosed " theft proof strongbox lock " by name, the patent No.: 206620114671.1, this theft proof strongbox lock comprises digital dial, locking plate and opening mechanism, it is characterized in that having more than one radial groove on the circumference of locking plate, the degree of depth of one of them groove is greater than the degree of depth of other groove.The utility model is the improvement on existing safety cabinet lockset basis, a plurality of degree of depth have been opened on the locking plate with existing safety cabinet less than the groove of opening with fore shaft, the effect of this groove is to make illegally not open the person by feel or other technical method opening safety cabinet the time, can't or be difficult to find the fore shaft on a plurality of locking plates to overlap the position vertically, prevent illegal purpose of opening thereby reach.Simultaneously, owing to the button handsetting of the projection on the digital dial is become a pit, just can prevent that illegal opener from pulling up digital dial and coupled axle by instrument, reaches the purpose that illegally opens, but this technical scheme might be opened by the mode of listening.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of can preventing to unblank by feel, has to prevent the theft proof strongbox coded lock of unblanking by the mode of listening.
For achieving the above object, the technical solution of the utility model is: a kind of theft proof strongbox coded lock, comprise the digital dial that is fixed on the safety cabinet and be installed in lock shaft end face and the corresponding button handsetting of digital dial, and be installed in locking plate and opening mechanism on lock shaft, the axle sleeve, on the circumference of locking plate, have more than one radial groove, the degree of depth of one of them groove is greater than the degree of depth of other groove, it is characterized in that a ring tooth is arranged on the circumference on the lock shaft, and the detent mechanism of being made up of steel ball and spring is installed on the corresponding axle sleeve of ring tooth.
Above-mentioned locking plate is a polygon.
Above-mentioned button handsetting is dismountable to be installed on the lock shaft end face.
Dismountable structure has the projection that matches with two holes at the lock shaft end face two different axial holes of the degree of depth to be arranged on button handsetting.
The utility model is the improvement on existing safety cabinet lockset basis, 1, will have the circular locking plate of safety cabinet now, change the polygon locking plate into, and so just improved the difficulty of unblanking by feel; 2, on lock shaft, be provided with the device of forming with ring tooth by steel ball, spring identical with positioner of the prior art, the purpose of this device mainly is the sound that produces during by steel ball and ring tooth relative motion, reaches the purpose that interference is illegally unblanked by sound; 3, change button handsetting into removably, also improved the difficulty of illegally unblanking.By above-mentioned improvement, the utlity model has characteristics rational in infrastructure, that theftproof is high.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the structural representation of the utility model locking plate;
Accompanying drawing 3 is the A-A sectional view of the utility model accompanying drawing 1.
The specific embodiment
As shown in Figure 1, on the door 1 of safety cabinet, digital disk 2 is installed, stir dish 6 and be marked with positioning pointer 3, button handsetting 4 is fixed on to be stirred on the dish, have two different axial holes of the degree of depth in the left side of lock shaft 7, the projection 5 that matches with two holes is arranged on the button handsetting, lock shaft 7 rotatable being installed in the axle sleeve 10, the right-hand member of lock shaft 7 is equipped with initiatively locking plate 9, at the right-hand member of axle sleeve two passive locking plates 8 is installed.Stirred dish at 6 o'clock by button handsetting 4 rotations, drive initiatively locking plates 9 rotations by lock shaft 7, rotate by two passive locking plates of active locking plate drive, when the fore shaft 13 on three locking plates overlapped vertically, the turned position opening mechanism just can be opened safe door.
As shown in Figure 3, on the lock shaft between the door of safety cabinet and the passive locking plate, a ring tooth 12 is arranged, the detent mechanism of forming by steel ball 11-1 and spring 11-2 with installation on the corresponding axle sleeve 10 of ring tooth 11.When lock shaft rotated, steel ball is bob on ring tooth, will produce impact sound, can disturb and utilize sound illegally to unblank.
As shown in Figure 2, three locking plates be shaped as polygon, on polygonal circumference, have three grooves 14 darker or more shallow with respect to fore shaft 13, when illegal opener forwards three grooves 14 on the circumference of three locking plates or groove and two fore shafts 13 when overlapping vertically to by feel, since the degree of depth of groove 14 less than or greater than the depth of groove of fore shaft 14, during the turned position opening mechanism, safe door can't be opened, play antitheft effect.So except that the groove of fore shaft, other groove is the illegal opener's of fascination " a pseudo-fore shaft " on three locking plates.
In order to prevent illegal opener by the number of observing and record is unblanked, will stir dish after the use and go down, the person that illegally do not unblank can't judge the particular location observed and number that record is unblanked, improve theftproof performance.
