Fig. 1 is the perspective exploded view of the utility model embodiment;

Fig. 2 is lock core perspective exploded view embodiment illustrated in fig. 1;

Fig. 3 is spacing hole structural representation embodiment illustrated in fig. 1.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in the figure, the lock housing 1 that is consisted of by steady pin 2 and capping 5, two zinc metal hook sheets 3 are connected on lock housing 1 inside wall by hook sheet stage clip 4, between two zinc metal hook sheet 3 upper end ledges, distance is less than the outer barb-like width of dead bolt 6 stems, fixing hole 7 is positioned on dead bolt 6, by fixing hole 7, dead bolt is fixed on the case lid sidewall, Fig. 3 is spacing hole structural representation embodiment illustrated in fig. 1, spacing hole 21 is positioned at lock body, be opened on lock housing 1 top, be arranged in dead bolt 6 moving conduits, width is greater than the outer barb-like width of dead bolt 6 stems.

When closing casing, dead bolt 6 is passed down through spacing hole 21 on lock housing 1 by the action of closing case lid, pushing two zinc metal hook sheets 3 moves laterally, zinc metal hook sheet 3 is owing to being connected with hook sheet stage clip 4 elasticity, hook sheet stage clip 4 is compressed, between outstanding position, two zinc metal hook sheet 3 upper ends, distance increases, make outstanding position, zinc metal hook sheet 3 upper ends and the outer barb stem of dead bolt 6 (the dead bolt 6 the widest parts of passing lock housing 1 are outer barb-like stem) interlock mutually, reach the purpose of autoshutdown casing.

Fig. 2 is lock core perspective exploded view embodiment illustrated in fig. 1, as shown in Figure 2, lock core shell 10 is fixed on lock housing 1 by screw 20, lock core shell 10 has been equipped with the decoration ring 9 of modification, lock core comprises internal cylinder 11 and outer lock core 12, lock core inside has been equipped with locking cap 19 and the alignment pin 17 of fixing interior outer lock core effect, internal cylinder 11 front end both sides all connect a plectrum 16, when the distance between plectrum 16 is locked locked state greater than automatic pellet case, the distance that two zinc metal hook sheets are 3, two zinc metal hook sheets 3 are arranged on the rotate path of plectrum 16, two rollers 18 of lock core front end roll with two plectrums of internal cylinder front end 16 respectively and are connected, outer lock core 12 inwall both sides connect respectively marble pressuring spring 15, marble pressuring spring 15 other ends connect lower pellet 14, the upper pellet corresponding with lower pellet installed respectively in internal cylinder 11 both sides.

control by key 8 and open casing, after key 8 puts in lock core, pellet 13 and lower pellet 14 in extruding, pellet screens up and down under the effect of marble pressuring spring 15, if up and down pellet link place is consistent with internal cylinder 11 and outer lock core 12 junctions, rotate clockwise key 8, when internal cylinder 11 is rotated, can be with the plectrum 16 of internal cylinder front end, roller 18 rotates (roller 18 plectrum is rotated and screens more smooth and easy), because zinc metal hook sheet 3 is on the rotate path of plectrum 16, so plectrum 16 extruding zinc metal hook sheets 3, and the groove location that rests on zinc metal hook sheet 3 (does not mark groove in figure, groove blocks plectrum, plectrum is no longer rotated), zinc metal hook sheet 3 is extruded hook sheet stage clip 4 laterally, hook sheet stage clip 4 shrinks, between two zinc metal hook sheets 3, distance increases, zinc metal hook sheet 3 upper end ledges and the outer barb-like stem of dead bolt 6 are separated from each other, remove interlock, open casing.

Although embodiment of the present utility model is open as above, but it is not restricted to listed utilization in manual and embodiment, it can be applied to the various fields of the present utility model that are fit to fully, for those skilled in the art, can easily realize other modification, therefore do not deviating under the universal that claim and equivalency range limit, the utility model is not limited to specific details and illustrates here and the legend of describing.
