With reference to accompanying drawing, have on the connector 1,9 fixture 13 will lock due to this, volume hold front cover firmly, the butt hook of connector 9 colludes in the hole 11 of outer box into.Projection 10 is gone to the bottom and is the plane, is curved surface above.Be the plane above the dead bolt tongue end, be below and the corresponding curved surface of projection curved surface.In the time of need locking, dead bolt is pressed down, the dead bolt lower surface camber withstands the projection 10 of slide block 7, and then pressuring spring 6, drive slide block again to two lateral movements, sliding-tongue tongue end is entered in the groove of slide block, projection, spring lose pressure, projection is back to original position under the spring return action, dead bolt is fixed in the slide block groove.

Fig. 4 key is inserted from lockhole 12, half-twist, key increment 14 tops are to another side of slide block groove coupling, slide block is to two lateral movements and compress spring, can extract dead bolt out this moment from groove, will this, volume opens.For writing, leaf through conveniently, outer box can open along butt hook hook end, and lock box and basis, volume are on the plane.

The utility model dead bolt, slide block are two, and locking firmly.Have only slide block, spring in the lock box, simple in structure, cost is low.The size of slide block, spring according to this, thick, the Bao Keda of volume, can be little, lock box also can make long and narrow, thereby both can be suitable for thick basis, volume, also applicable to the basis, the volume that approach.
