The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to describe.
Fig. 1 is the utility model lock door mechanism mounting structure sketch map.
See also Fig. 1; The lock door mechanism that the utility model provides comprises main lock 6, the secondary lock 5 that is fixed on the door-plate 1 and draws gear mechanism; The said gear mechanism that draws comprises handle 2, handle axle 3, dead bolt bayonet socket rotating disk 4, side door door bolt 7 and following bolt 8, handle axle 3 and the 4 coaxial settings of dead bolt bayonet socket rotating disk, and side door door bolt 7 links to each other with dead bolt bayonet socket rotating disk 4 through side door door bolt connecting rod 10; Following bolt 8 passes through down, and bolt connecting rod 9 links to each other with dead bolt bayonet socket rotating disk 4; Wherein, said lock door mechanism also is provided with secondary lock 5, and secondary lock 5 contacts with dead bolt bayonet socket rotating disk 4 through interlocking slide plate 18.
The disclosed lock door mechanism of the utility model is applicable to safe, ATM storage paper money cabinet; A complete set of mechanism is installed on the door-plate 1; The handle 2 that opens the door of door-plate 1 links together through handle axle 3 and dead bolt bayonet socket rotating disk 4; Main lock 6 and secondary lock 5 are housed on the door-plate, and main lock 6 can be selected the rotating disc type mechanical code lock for use, and secondary lock 5 can be selected key formula mechanical code lock for use.Have only main lock 6 to lock earlier when locking a door; Its dead bolt stretches out, and the interlocking slide plate 18 that promotes to be installed on the dead bolt bayonet socket rotating disk 4 moves down, and just can make the dead bolt of main lock 6 stopping of slide plate 18 of avoiding interlocking put in the corresponding bayonet socket of dead bolt bayonet socket rotating disk 4 secondary lock 5 is locked; Just can extract the key of secondary lock 5; Avoided the leakage lock (main lock 6 is not locked, and secondary lock 5 is not lock and can not pull out key) of main lock 6, as shown in Figure 2.Must lock 6 (having improved the size of key of unblanking) with the master by open auxiliary lock 5 when unblanking; Make their dead bolt withdraw from the bayonet socket of dead bolt bayonet socket rotating disk 4; Just can rotate counterclockwise the handle 2 that opens the door and drive 4 rotations of dead bolt bayonet socket rotating disk; Thereby promote to be connected following bolt connecting rod 9, side door door bolt connecting rod 10 on the dead bolt bayonet socket rotating disk 4 and drive down that bolt 8 and side door door bolt 7 move to opening position, accomplish the action of opening the door, as shown in Figure 3.
In order further to improve security performance; Can further be provided with on the lock door mechanism that the utility model provides and heavily lock spring catch; As shown in Figure 4, the concrete realization as follows: between door-plate 1 and main lock 6, be provided with armorplate glass 11, armorplate glass 11 can be fitted on the door-plate 1 as far as possible.Heavily lock between the spring catch at armorplate glass 11 and to be connected with pull line 12, just often cable wire 12 is tension with each, heavily lock in the spring catch spring by compression, shank is sunk to heavily locks in the spring key seat, offside bolt 7, the action of bolt 8 does not have influence down.When the bin outer side of door receives the offender when knocking with sudden force; Armorplate glass 11 is pulverized; Cause pull line 12 lax, make and heavily lock the spring shank and under the stage clip effect, stretch out and heavily lock the spring key seat, the shank of the first heavy lock pin 13 and the second heavy lock pin 14 puts in down the bayonet socket of bolt 8; The shank of quadruple lock pin 16 puts in the bayonet socket of side door door bolt 7, has stoped side door door bolt 7, bolt 8 mobile reaches the purpose that bolt is heavily locked down.When main lock 6 is receiving when thumping outdoors; Fixedly the main stopper sheet 17 of lockset comes off, and is fixed on shank reason master stopper sheet 17 shutoff of the triple lock spring catch 15 on the door-plate 1, because of main stopper sheet 17 comes off; Put in the bayonet socket of dead bolt bayonet socket rotating disk 4 in the shank of triple lock spring catch 15 is present under the effect of stage clip; Stop the rotation of handle 2, blocked the action of unblanking to open the door, reached the heavily purpose of lock enhancing anti-theft feature.
Though the utility model discloses as above with preferred embodiment; Right its is not in order to limit the utility model; Any those skilled in the art; In spirit that does not break away from the utility model and scope, when can doing a little modification and perfect, so the protection domain of the utility model is when being as the criterion with what claims defined.
