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 strongbox self-locking mechanism sketch map.

See also Fig. 1; The strongbox self-locking mechanism that the utility model provides comprises electronic password lock 10, the feeler lever 4 of closing the door, draw grade slide plate 1, handle rotating shaft 7 and a plurality of bolt 13, and the said grade slide plate 1 that draws is provided with L type chute 2 and dead bolt seam 12, and the said feeler lever 4 of closing the door is fixedly linked through connecting pin 3 and L type rotor plate 6; Said handle rotating shaft 7 is provided with driving lever 8; A plurality of bolts 13 link to each other through bolt junction plate 17, and wherein, an end of said L type rotor plate 6 is provided with extension spring 5; The other end is located in the L type chute 2 through straight pin, and said bolt junction plate 17 is provided with stage clip 9.

Above-mentioned strongbox self-locking mechanism, stage clip 9 and bolt were opened in the both sides of bolt junction plate 17 in 13 minutes, and the number of said stage clip 9 is preferably two, is symmetrical set up and down.

Fig. 2 is the utility model strongbox self-locking mechanism door opening state sketch map; Fig. 3 is the utility model strongbox self-locking mechanism view of closing the door.

The course of work and the operating principle of above-mentioned self-locking mechanism are then described below.

Please continue referring to Fig. 2; When opening the door: behind the input proper password; The rotation dead bolt 11 of electronic password lock 10 shifts out dead bolt seam 12, and the handle that opens the door rotates handle rotating shaft 7, drives and draws a grade slide plate driving lever 8 will draw grade slide plate 1 to move to left together with bolt 13; Stage clip 9 pressurizeds on this moment bolt junction plate 17, straight pin is positioned at the low order end of L type chute 2 horizontal segments that draw on grade slide plate 1 on the L type rotor plate 6.When drawing back door-plate 15, the feeler lever 4 of closing the door leaves casing 14, can further be provided with hinge 16 between casing 14 and the door-plate 15, and is as shown in Figure 4.Under the effect of extension spring 5, L type rotor plate 6 clockwise rotates, and makes its straight pin get into the vertical section step of L type chute 2, the door opening state after entire mechanism being remained on unblank.

Please continue referring to Fig. 3, at closing time:

When pushing close the door door-plate to position; The feeler lever 4 of closing the door receives casing 14 bruisings, and L type rotor plate 6 rotates counterclockwise, and its straight pin withdraws from the vertical section step of the L type chute 2 that draws grade slide plate 1; Draw grade slide plate 1 under the promotion of stage clip 9, to move to right together with bolt 13; Coded lock rotation dead bolt 11 gets into the dead bolt seam 12 that draws grade slide plate, and mechanism gets into the state of locking a door, and accomplishes the action of locking a door automatically.
