Description
Technical field
The invention belongs to the locking device technical field of safe door, safety door, what relate generally to is the two-door interlock locking device of clamshell doors of a kind of safety cabinet and similar products.
Background technology
At present, the locking of known all kinds of safety cabinets, safety door adopts simple gate control usually, is promptly finished its unlatching or locking function by a door.This locking mode just seems heavy when running into that the cabinet volume is bigger to need configuration two-door, not only opens or the locking inconvenience, but also has certain potential safety hazard.As existing two-door big safety cabinet, the interlock modes that adopt right door pressure left-hand door limit are promptly only installed locking mechanism more on right door, and left-hand door does not then have this function, so the safety of left-hand door is relatively poor, is pried open easily.
Summary of the invention
Purpose of the present invention promptly produces thus, proposes the two-door interlock locking device of clamshell doors of a kind of safety cabinet and similar products.Realize two-door interlock locking, further improve the safety and reliability of safety cabinet.
The present invention realizes that the technical scheme that above-mentioned purpose is taked is: it is made of fingerprint recognition mechanism, handwheel, locking mechanism, handle and connecting rod mechanism and the shift fork and the limiting plate that are arranged on the cabinet body door, locking mechanism and fingerprint recognition mechanism are arranged on on the Yishanmen, form by bolt, slide plate, lead, eccentric wheel and motor, bolt is two and is fixedly connected on the nose, eccentric wheel eccentric part reversed column is that sliding pair is connected with slide plate, core is connected with motor output end, and fingerprint recognition mechanism is connected by cable with motor; Handle and connecting rod mechanism and handwheel, shift fork and limiting plate are arranged on on the Yishanmen, form by connecting rod, handle and connecting rod, last locking bar, handwheel, guide strip, spring and following locking bar, one end of connecting rod, last locking bar and following locking bar all is connected with handle and connecting rod, guide strip, spring housing are connected on down on the locking bar, the other end of handle and connecting rod is that sliding pair is connected with the rear end of shift fork, and limiting plate is arranged on the shift fork below.
The present invention is reasonable in design, easy to operate.Because it is provided with locking mechanism on double door, realize two-door interlock locking, has further improved the safety and reliability of safety cabinet and similar products thus.And the application of guide strip and spring has realized the auto-lock function of door body when locking in the handle and connecting rod mechanism, saves the step of rotating handwheel at closing time, saves time and laborsaving.

The specific embodiment
It is as follows to provide embodiments of the invention in conjunction with the accompanying drawings:
As shown in Figure 1: present embodiment is made up of handle and connecting rod mechanism 5 that is arranged on shift fork 9 on the right door 6 and shift fork and the fingerprint recognition system that is arranged on the locking mechanism 4 on the left-hand door 1 and drives locking mechanism.This embodiment is a kind of mounting means wherein.The handle and connecting rod mechanism 5 of shift fork 9 and shift fork is not limited to also can be arranged on left-hand door 1 on the right door 6.Equally, the fingerprint recognition system of locking mechanism 4 and driving locking mechanism also is not limited on the left-hand door 1, also can be arranged on the right door 6.
What fingerprint recognition mechanism adopted is known technology, be made up of main control board 2, fingerprint recognition panel 3, connection cable 10: main control board 2 is connected via cable 10 with fingerprint recognition panel 3, cable 10 links together the motor 16 on fingerprint recognition system and the locking mechanism 4 again, guarantees the smooth transmission of signal thus.
As shown in Figure 2: locking mechanism 4 is made up of bolt 12, slide plate 13, lead 14, eccentric wheel 15, motor 16: bolt 12 is two, be welded on the front end of slide plate 13, slide plate 13 is provided with gathering sill, the lead 14 that is welded on the left-hand door 1 adopts sliding pair to be connected with this gathering sill, thereby makes slide plate 13 be connected and guarantee the normal slip of slide plate 13 with left-hand door 1; Eccentric wheel 15 eccentric part reversed columns adopt sliding pair to be connected with another gathering sill on the slide plate 13 equally, core is connected with motor 16 outputs, when motor 16 receives that the signal energising is rotated, eccentric wheel 15 just drives slide plate 13 and slides under it drives, bolt 12 is inserted on the right door 6 accordingly in the latch hole accurately.
As shown in Figure 3: handle and connecting rod mechanism 5 is made up of connecting rod 17, handle and connecting rod 19, last locking bar 20, handwheel 22, guide strip 24, spring 25, following locking bar 26.Handle and connecting rod 19 essence are the regular triangle structure of variation, are connected also by screw 23 with the handwheel 22 that is arranged on right door 6 external surfaces and rotate thereupon.The triangle portion of handle and connecting rod 19 be connected with respectively connecting rod 17, on locking bar 20 and locking bar 26 down, last locking bar 20 passes through bearing pin 21 and is connected with handle and connecting rod 19; Be socketed with guide strip 24 and spring 25 on the locking bar 26 down; One end of connecting rod 17 is connected with handle and connecting rod 19 by pivot pin 18, and the other end adopts sliding pairs to be connected by bearing pin 18 with the shift fork 9 that is arranged on right 6.Shift fork 9 is fixedlyed connected with right door 6 by the support 8 of band nut, is provided with limiting plate 7 below shift fork 9, and its effect is the slewing area of restriction shift fork, thus the normal operation of assurance mechanism and unlikely generation misoperation.
Present embodiment in use, open cabinet in front of the door, must on fingerprint recognition panel 3, gather fingerprint, main control board 2 with the fingerprint that collects within it portion carry out the fingerprint comparison verification, checking by the back by cable 10 signal is passed to motor 16, motor 16 promptly switch on the rotation and the drive eccentric wheel 15 rotate together, slide plate 13 under the driving of eccentric wheel 15 to left, broken away from 2 corresponding latch holes on the right door frame thereby make with two bolts 12 that slide plate 13 welds together, left-hand door is opened; Meanwhile the spacing of 12 pairs of shift forks 9 of bolt also removed thereupon.Turn handwheel 22 this moment, handle and connecting rod 19 also rotates thereupon, thereby locking bar 20 is gone up in drive and following locking bar 26 is downward respectively, moving upward breaks away from the latch hole of correspondence on the door frame, makes the 6 spacing releasings of closing of right door, can open and get thing.At closing time, because the sagging latch hole that is keeping off right door 6 of the front end of shift fork 9, when closing simultaneously as if left and right door, the bolt 12 of locking mechanism 4 advances less than in the corresponding latch hole in the left-hand door 1, and left-hand door 1 just can't be closed.So must close right door 6 earlier, left-hand door 1 could be closed smoothly.When so just having avoided left and right door to close simultaneously, the motor that causes not in place of closing the door continue to rotate and the phenomenon of burning motor.
Shown in Fig. 4,5, following locking bar 26 lower ends are the hemispherical head shape, closed right door at 6 o'clock, the right door 6 of available have gentle hands light press, the following locking bar 26 of outstanding right door 6 promptly contacts extruding and produces certain precompression with cabinet, spring 25 just is out of shape in the restriction lower compression of pushing of this precompression and guide strip 24, because down the hemispherical head of locking bar 26 lower ends has and is subjected to the characteristic that the certain pressure effect just produces motion, move and drive handle and connecting rod on the following locking bar 26 of institute rotates thereupon, last locking bar 20 also moves down, the spacing releasing of closing the door, right door is closed.So just realized the door auto-lock function of body when locking, saved the step of rotating handwheel at closing time, saved time and laborsaving.
