Abstract:
1. A press-buckled lock comprising: an inner sleeve being a hollow body; a washer enclosing a middle section of the inner sleeve; a press buckle having an extension portion at a front end thereof; the extension portion inserting into a rear end of a round sleeve; another end of the round sleeve having an opening; a spring being installed in the opening; a front end of the round cover; a bottom cover being embedded into the opening of the round sleeve; then the round sleeve being placed into a rear side of the inner sleeve; the press buckle having a head portion at a rear end thereof; a spring being installed to the head portion of the press buckle; a periphery of the spring being enclosed by an actuating sleeve; an inner handle having a head portion; the press buckle with the inner sleeve being received within the inner handle; the head portion of the press buckle being inserted into a round hole at one end of the inner handle so as to protrude out of the inner handle; part of the actuating sleeve being inserted into the head portion of the inner handle and other part thereof being exposed out of the head portion of the inner handle; the inner sleeve being received within the inner handle so as to be combined thereto; an upper end of the inner handle being pressed so that a buckle tip at the inner side of the inner handle being buckled into a recess at an upper side of the inner sleeve so as to prevent the inner handle to move out; an inner panel having a central hole; the inner sleeve passing through the inner panel so that the inner panel, the inner sleeve and the inner handle being assembled as an integral body; then a confining sheet, a second resilient spring, and an inner spring seat sequentially passing through the inner panel; an elastic opening ring being embedded into an annular trench at a front end of the inner sleeve as a confinement; an outer sleeve; an inner wall of the outer sleeve having two projections; one end of the outer sleeve having four connecting sheets; a lock core being combined within the outer sleeve; the lock core having a projection; a front end of the lock core having a guide structure; an outer handle having a head portion; an inner side of the outer handle having a buckled tip; the outer sleeve and the lock core being placed in the head portion of the outer handle; the projection of the lock core being buckled into a long hole at the head portion of the outer handle; the buckled tip being buckled in a recess on an outer periphery of the outer sleeve so as to prevent the outer handle to protrude out; the guide structure having a plurality of protrusions; a plurality of guiding recess being formed between two protrusions; a top of each protrusion being formed with a tip teeth; the outer sleeve passing through the outer panel and a front section of the outer sleeve protruding out thereof; a buckling rod having a front section and a rear section which are formed as an H shape; a positioning sheet being positioned in a middle section of the two sections; the rear section being engaged with a positioning seat; the sides of the positioning seat having respective ears which are inserted into the lateral recesses at two sides of a positioning unit; each ear having a penetrating hole corresponding to a penetrating hole in a corresponding recess of the positioning unit for receiving a pin so as to fix the positioning seat to the positioning unit; thus, the front section of the buckling rod being confined in the positioning unit; thereby the buckling rod, positioning sheet, positioning seat and positioning unit having formed as an integral body; a front section of the positioning unit having a guide out unit which is formed by a plurality of block; a plurality of guide trenches being formed between the blocks; one side of each block being an inclined surface so that the block is formed as a tip teeth; a lateral side of the positioning unit having a through hole at a lateral side thereof for receiving a positioning spring; wherein in assembly, the buckling rod, positioning sheet, positioning seat, and positioning unit are inserted into the outer sleeve; the positioning spring are buckled to the two projections at the inner wall of the outer sleeve, the four connecting sheets at one end of the outer sleeve are inserted into the lock core so as to confine the buckling rod, positioning sheet, positioning seat, and positioning unit not to fall out; the outer tube is installed between the outer panel and the inner panel; the buckling rod inserts through a first rectangular iron tube and a second rectangular iron tube; the outer tube, first rectangular iron tube and second rectangular iron tube are inserted into a switch hole of a lock seat; thereby by driving the two handle, the lock seat is driven to insert a rear section of the buckling rod into the inner sleeve so as to be further inserted into an interior of the press buckle in the inner handle and confine above mentioned elements; wherein by pressing the press buckle, a lock can locked rapidly; when rotating the inner handle or inserting a specific key into the lock core, the press buckle will separate rapidly so as to unlock the lock; thus, the press buckle in the lock has the effect of controlling the locking and unlocking operation rapidly.
