Description

Multistage multiple dead bolt interlock safety cabinet

A kind of multistage multiple dead bolt interlock safety cabinet belongs to anti-stealing safety equipment.

Before the utility model is made, the ZL patent No., 94226529.7 " multistage multiple dead bolt interlock safety cabinets " are advanced, and this safety cabinet mainly by door, casing cabinet, coded lock, theftproof lock, form by the dead bolt link gear.A vertical side door is equipped with many dead bolts cashier's office in a shop, and laterally doorframe has only a dead bolt up and down, and dead bolt is by being provided with about multistage multiple dead bolt link gear in the inboard chamber of door, and linkage from top to bottom makes the dead bolt synchronous interaction, and door is opened or closed.Though this kind structure is simple, easily bring the possibility of being pried open, and in use, door is opened to put down and is reached 180 ℃ position to stolen, area occupied is big during use, makes troubles to the user.

The purpose of this utility model is to overcome above-mentioned weak point, can increase antitheft firmness thereby provide a kind of, appearance looks elegant, and door all is equipped with the multistage multiple dead bolt interlock safety cabinet of many dead bolts all around.

The utility model is realized by following proposal:

The utility model is mainly by door (26), casing cabinet, coded lock (6).Theftproof lock (18), multistage multiple dead bolt link gear is formed multistage multiple dead bolt link gear and is comprised guide plate (12), tooth bar (17), driving gear (21), driven gear (23), transmit gear (24), driven gear (25), connecting rod (2), (3), upright lock tongue (5) (5 ') up and down, cross locking tongue (13), (13 '), (13 ") are formed; tooth bar (17) is connected as a single entity with guide plate (12); cross locking tongue (13); (13 '); (13 ") are installed on the guide plate (12), driving gear (21) drives tooth bar (17), driving gear (21) and driven gear (23) engagement, on connecting rod (3) branch, following two are separately fixed on the driven gear (23), driven gear (23) drives driven gear (25) by transmitting gear (24), on connecting rod (2) branch, following two are separately fixed on the driven gear (25) connecting rod (2), (3) on, upright lock tongue (5) up and down is housed respectively down, (5 ').

Description of drawings:

Fig. 1 is the utility model outside drawing.

Fig. 2, Fig. 3 are the utility model structural front view.

Following the utility model is further described middle in conjunction with the accompanying drawings embodiment:

Embodiment one:

Door is connected casing cashier's office in a shop, and the door another side is equipped with fixedly dead bolt (1), (1 ') (1 ").Casing cashier's office in a shop corresponding position has the hole, on the door coded lock (6) is housed, have password breach (7) on the coded lock (6), carriage (16) is gone up and be equipped with to coded lock (6), password armature (11), the solid pin (8) of retaining tongue (10) and password armature, in the bottom of turning handle (5) the different tooth theftproof locks of many ribs (18) are housed, handle is installed in the middle part of insurance frame door, in the inboard chamber of door, the handle axle head is equipped with the driving gear (21) of multistage multiple dead bolt link gear, adopt fixture (22) fixing, it is meshed with the tooth bar (17) that the guide plate that is in doorframe one side (12) is connected as a single entity, have tipper through hole (15) on the guide plate (12), the corresponding horizontally disposed dead bolt (13) that is with inclination slotted eye (15), (13 '), (all be fixed with pilot pin (14) on the plane of 13 "), pilot pin (14) is in the top on each tipper through hole (15) top respectively.Dead bolt is installed in the guide plate (12) flexibly.Stop block (20) is limited guide plate (12), dead bolt (19) on the different tooth theftproof locks of many ribs (18) is on the stop block (20), driving gear (21) is meshed with driven gear (23), driven gear (23) drives driven gear (25) by transmitting gear (24), go up with the fixing upper and lower connecting rod (3) of pin at driven gear (23), upper and lower connecting rod (3) is fixed upper and lower dead bolt (5 ') respectively, and guide holder (9) also is housed respectively on upper and lower dead bolt, (5 ').Adopt pin to fix upper and lower connecting rod (2) on driven gear (25) too, upper and lower connecting rod (2) adopts pin (4) to fix upper and lower dead bolt (5) respectively, and guide holder (9) is housed respectively on the dead bolt (5).When driving gear (21) drive driven gear (23) clockwise rotates its edge, upper and lower connecting rod (2), (3) also angle of deflection swing thereupon under the drive of pin, thus make upper and lower connecting rod (2), (3) drive dead bolt (5) in the upper and lower doorframe, (5 ') along the set bearing separately of vertical to the inboard chamber indentation slidably of door.

When each dead bolt is in blocking, in this state, the horizontally disposed dead bolt of vertical doorframe one side (13,13 ', the pilot pin (14) on 13 ") all is in (15) the one sections tops for the through hole of vertical of tipper through hole on the guide plate (12); saddle (16) the both sides groove through hole of theftproof lock (18) also is in the upper end of these groove through holes; at this moment, and the dead bolt (19) of the different tooth theftproof locks of many ribs (6) is on the stop block (20) on the guide plate (12).

In the time will opening safety cabinet, at first coded lock (6), theftproof lock (18) are opened, theft-proof bolt (19) withdraws from stop block (20), then by clockwise rotating handle, driving gear (21) drives tooth bar (17) to the motion of vertical side, upper edge, and (pilot pin of 13 ") (14) forces dead bolt to move horizontally along separately bearing along skewed slot through hole (15) respectively to be fixed on dead bolt (13), (13 ').When driving gear (21) drive tooth bar (17) moved upward, it is transmission driven gear (23) again, and driven gear drives transmission gear (24) and driven gear (25) synchronously is rotated in a clockwise direction.Each connecting rod just forces upright lock tongue (5) (5 ') indentation in the inboard chamber of safe door, and the door of safety cabinet just can be opened.For door being opened most 180 ℃ of positions, in the casing cabinet and the junction of door back-flap hinge is housed, after door opens, perhaps shut the door, as long as coded lock and theftproof lock are in opening, all dead bolts are under the effect of hanging down certainly of guide plate (12), and are just overhanging automatically by the inboard chamber of door.When door was shut, dead bolt also made door automatically enter blocking too under the effect of guide plate (12), and with on different tooth theftproof locks of many ribs (18) and the coded lock full lock, this safety cabinet just is in security and anti-theft blocking completely in this case

Embodiment two:

The multistage multiple dead bolt link gear of the utility model adopts tooth bar (17) and guide plate (12) to be connected as a single entity, cross locking tongue (13), (13 '), (13 ") are installed on the guide plate (12); driving gear (21) drives tooth bar (17); driving gear (21) and driven gear (23) engagement; on connecting rod (3) branch; following two are separately fixed on the driven gear (23); driven gear (23) drives driven gear (25) by connecting rod (24), on connecting rod (2) branch, following two are separately fixed on the driven gear (25) connecting rod (2), (3) on, be equipped with respectively down, following upright lock tongue (5), (5 '), other structure of safety cabinet is same as embodiment one.

Compared with the prior art the utility model has the following advantages:

1, owing in safety cabinet casing and four sides of door many dead bolts being housed all, wherein The medial surface dead bolt is fixed, and more is conducive to anti-stealing safety; 2, link gear is rationally distributed, Simple in structure, each dead bolt synchronous interaction of four sides is opened or closed the door of safety cabinet, 3, Open and use conveniently, can make door be open at 180 ℃ of positions of level, take up space less, firm Reliably, operation, aesthetic in appearance.
