Catch 6 comprises the outer panel 61 that is arranged on axle sleeve 31 outsides, respectively from the last flap 62 of the upper and lower side direction inner bending of outer panel 61 and lower flap portion 63 and from the inboard base plate 64 of bending downwards of lower flap portion.

Be provided with blocking pin 65 on lower flap portion 63, offer in the bottom surface of axle sleeve 31 for what blocking pin 65 passed and stop pin-and-hole 311, stop pin-and-hole 311 and stairstepping through hole 310 vertical communicating, blocking pin 65 is located in and stops in the pin-and-hole 311.On base plate 64, be provided with first gathering sill 66, the spring steady pin 67 of vertical extension and second gathering sill 68 that vertically extends from top to bottom successively.On dead bolt handle 11, be provided with the first catch guide finger 111 and the second catch guide finger 112, the first catch guide finger 111 is located in the gathering sill 66, the second catch guide finger is worn 112 and is located in second gathering sill 68, preferably, second gathering sill 68 and first gathering sill 66 are located on the same line.

Slide plate 7 is arranged on the outside of catch 6.On slide plate 7, be provided with the horizontally extending first waist hole 71 and the second waist hole 72 and can drive the descending hole 73 that spring steady pin 67 moves down, the equal in length in the first waist hole 71 and the second waist hole 72, the spring steady pin 67 that is arranged on the catch is located in the descending hole 73.In the utility model, descending hole 73 is preferably triangle.Yet those skilled in the art are easy to expect, adopt the hole of other shape with a hypotenuse feasible equally.Be provided with the first slide plate guide finger 113 on the dead bolt handle 11 and the second slide plate guide finger, 114, the first slide plate guide fingers 113 are located in the first waist hole 71, the second slide plate guide finger 114 is located in the second waist hole 72.Preferably, the first waist hole 71 and the second waist hole 72 are located on the same line.Be provided with back-moving spring 69 between the first catch guide finger 111 and spring steady pin 67, the upper end of back-moving spring 69 links to each other with the first catch guide finger 111, and the lower end links to each other with spring steady pin 67.

On slide plate 7, also be provided with pin 74.Rotation plectrum 8 is arranged on the top of slide plate 7, comprises body 81 and is arranged on the cantilever 82 of body outer rim, and cantilever 82 is arranged on pin back in a side of block 4.The rotation plectrum links to each other with the door handle that is positioned at safety cabinet cabinet door inboard, during door handle, rotates plectrum 81 and swings thereupon in rotation, stirs the pin 74 drive slide plates 7 that are fixed on the slide plate 7 by cantilever 82 and moves horizontally to the block direction.

Catch 6 of the present utility model can move between the primary importance and the second place.When the safety cabinet lock body was in locking states, an end of push rod 32 stretched in the jogger hole 41, and the upper end of plug 52 is passed plug hole 42 and stretched in the jogger hole 41, and push rod 32 can't be moved towards the direction of block 4; Simultaneously, catch 6 is in primary importance, and as shown in Figure 1, the blocking pin 65 that is arranged on the catch 6 stretches in the stairstepping through hole 310 under the effect of back-moving spring 69.At this moment, the second step face 322 on the push rod can stop that blocking pin 65 moves to the direction of block 4 together with catch 6 and axle sleeve 31, thereby dead bolt assembly 2a can't freely be opened.

In the time will opening lock body from safety cabinet cabinet door is inboard, as shown in Figure 2, only need door handle 100 in cabinet door inboard clockwise rotates, stirring pin 74 drive slide plates 7 by interior door handle 100 is moved to the left, descending hole 73 on the slide plate 7 drives spring steady pin 67 and moves down together with catch 6, thereby make blocking pin 65 withdraw from stairstepping through hole 310, at this moment, catch 6 is positioned at the second place.When the right-hand member that is moved to the left the first waist hole 71 and the second waist hole 72 when slide plate 7 is resisted against the first slide plate guide finger 113 and the second slide plate guide finger 114, when continuing to be moved to the left as slide plate 7, then can drive the first slide plate guide finger 113 and the second slide plate guide finger 114 also is moved to the left together with dead bolt handle 11, axle sleeve 31, though plug 52 stops push rod 32 to be moved to the left, but the compression movement by means of 312 pairs of axle sleeve springs 33 of step surface of axle sleeve 31 can make side chain tongue assembly 2a freely open.

As shown in Figure 3, on dead bolt handle 11, also can be provided with a bearing pin 115.The one opening shift fork 9 that links to each other with outer door handle rotates around bearing pin 115.And arranged on left and right sides at the opening shift fork is connected with upper lock tongue 2b and following dead bolt 2c respectively.When dead bolt handle 11 is moved to the left, can drive opening shift fork 9 and rotate counterclockwise, upper lock tongue 2b is moved down, following dead bolt 2c moves up.Thereby for the safety factor that increases safety cabinet installs additional under the situation of upper and lower dead bolt, also can realize opening easily the cabinet door by the rotation of interior door handle.

Lock body of the present utility model can also cooperate existing emergent lock and password key to use.As shown in Figure 4, when cabinet uses emergent lock key to rotate counterclockwise outdoors, understand the last flap 62 that drives the all-or-nothing piece 200 clockwise swings that are positioned at an inboard and stir catch 6 downwards, thereby make blocking pin 65 withdraw from stairstepping through hole 310, rotate outer door handle this moment again, the opening shift fork 9 that links to each other with outer door handle is rotated counterclockwise, drive dead bolt handle 11 by bearing pin 115 and be moved to the left and open side dead bolt assembly 2a, upper lock tongue 2b and following dead bolt 2c, its principle is similar to door handle unlatching cabinet door in the above-mentioned utilization.As shown in Figure 5, after the user is by the correct password of password key input, make electromagnet 51 work, plug 52 adhesives, rotate outer door handle again, opening shift fork 9 is rotated counterclockwise, drive dead bolt handle 11 by bearing pin 115 and be moved to the left and open side dead bolt assembly 2a, upper lock tongue 2b and following dead bolt 2c, because push rod 32 is not subjected to stopping of plug 52, and can open the cabinet door smoothly.

Though description of the present utility model combines certain embodiments, it should be understood by one skilled in the art that the utility model is not limited to embodiment described here, and can make amendment and change and do not deviate from spirit and scope of the present utility model.Should think that the description of manual is schematic and nonrestrictive.
