Abstract
The invention relates to a lever type drawer locking mechanism which can lock and unlock a drawer without a key. The mechanism mainly comprises a support, a locking dog, link levers, a push plate, a pressure spring, a riveting shaft, a shaft sleeve, a gasket and a retainer ring which form a symmetric lever mechanism. The invention is characterized in that the upper end of the locking dog is an inclined plane (a wedge of 45 degrees from side view), the locking dog is always at high position under the action of the pressure spring, the locking dog is blocked by the edge of a drawer frame when being pushed into a drawer, horizontal resistance is applied on the inclined plane thereof, the resistance can be decomposed to be two component forces which are upward parallel with the inclined plane and downward vertical to the horizontal plane respectively, the component force downward vertical to the horizontal plane presses the locking dog and the locking dog contracts downward to low position, the drawer is smoothly pushed in place, and the locking dog is reset and enters into a locking hole on the drawer frame under the action of the pressure spring, so that the drawer is locked. When opening the drawer, the push plate is pressed upward, the push plate drives two link levers to rotate around respective pivot, and the other end of the link lever simultaneously drives the locking dog to move downward, so as to be separated from the lock hole, thus unlocking is realized and the drawer can drawn out. The invention can be applied to any furniture provided with drawer, locking and unlocking of drawer can be realized without a key, and a lock can not be found from the outside.
Description
Technical field
The present invention relates to a kind of lever drawer lock mechanism of exempting from can carry out with key locking and unlatching drawer, mechanism mainly is made of the leverage of a symmetry support, dead bolt, linkage lever, push pedal, stage clip, axle sleeve, riveting axle, packing ring and collar etc.
Background technology
At present, mostly known drawer-lock be to utilize key to lock and open drawer, and their common characteristic lock or open drawer exactly must use key, and this gives on the one hand and opens, locks drawer and increase time and operation link; Taking care of key on the other hand also is burden; If key loss, the trouble of bringing is just bigger.
Summary of the invention
In order to solve existing locking mechanism locking or to open the problem that drawer must use key, the objective of the invention is to provide a kind of device without key also lockable and unlatching drawer.
The technical solution adopted in the present invention is: support, dead bolt, linkage lever, push pedal, stage clip, axle sleeve, riveting axle, packing ring and collar etc. constitute the leverage of a symmetry.
Support is bent into by steel plate, and side is seen and is
Shape, just see and be
Shape inserts dead bolt and is
Shape, linkage lever is made by steel plate, in the form of sheets, 3 hinge axis holes are arranged on it, it is circular hole that bar is about 3/4 place, two ends are slotted hole (slotted hole definition: two radius equated but circular hole that the circle of decentraction forms along the parallel connection of diameter), linkage lever uses in pairs, the right symmetry of one the first from left is placed, linkage lever one end and dead bolt lower end are hinged by long riveting axle and axle sleeve, middle respectively with support about circular hole on two legs by riveting axle hinged (this point is balance pivot), the other end and push pedal are hinged by the riveting axle, install afterwards the front and see and be
Shape.The big up and small down multidiameter of dead bolt inserts in the concentric holes of " Contraband " shape above and below of support (two leg mid-depth lines are seen from the side and overlapped about the center line of this concentric holes and support), and small end is with stage clip and collar.The dead bolt upper end is designed to inclined-plane (side is seen and is 45 ° of angles of wedge), under the stage clip effect, be in a high position all the time, when advancing drawer, the dead bolt inclined-plane is subjected to horizontal thrust, thrust is decomposed into parallel inclined-plane upwards and two component facing down of vertical-horizontal, and the vertical-horizontal component pressure dead bolt that faces down makes it be reduced to low level downwards, and the accessible propelling of drawer puts in place, dead bolt resets and enters lockhole on the drawer frame under the effect of stage clip, and drawer promptly is lockable.When opening drawer, upwards by push pedal, two linkage levers of push pedal drive rotate around fulcrum separately, make the lever other end drive dead bolt simultaneously and leave lockhole downwards, promptly unblank, and drawer can be extracted out.
The invention has the beneficial effects as follows:
1. so long as design has the furniture of drawer all can use this locking mechanism;
2. be lockable and unlatching drawer without key;
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Accompanying drawing is unitary construction figure of the present invention, among the figure: 1. support, 2. dead bolt, 3. linkage lever, 4. push pedal, 5. stage clip, 6. the riveting axle is 7. grown the riveting axle, 8. axle sleeve, 9. packing ring, 10. collar.
The specific embodiment
In the accompanying drawings:
1, the small end with dead bolt [2] inserts in the concentric holes on upper and lower two planes of support [1] " Contraband " shape, simultaneously stage clip [5] is inserted the small end of dead bolt [2], make stage clip [5] between the big end end face of support [1] " Contraband " shape lower plane medial surface and dead bolt [2], small end from dead bolt [2] inserts packing ring [9] and collar [10] again, makes packing ring [9] and collar [10] outside at support [1] " Contraband " shape lower plane.
2, the end of two linkage levers [3] near middle circular hole, one in front and one in back clamp the circular hole plane of dead bolt [2] small end, make their 3 holes (2 slotted holes, 1 circular hole) concentric, make the inclined-plane of dead bolt [2] beveled end and support [1] with the face of 4 screwed holes in the same side, rivet with long riveting axle [7] and axle sleeve [8], be fixed on the dead bolt [2] after long riveting axle [7] and axle sleeve [8] riveted joint, linkage lever [3] can be gone up rotation at long riveting axle [7] and axle sleeve [8].
3, use riveting axle [6] to pass the riveted joint of the circular hole on two legs about linkage lever [3] circular hole and support [1] more respectively, riveted joint back riveting axle [6] is fixed on the support [1], and linkage lever [3] can be gone up at riveting axle [6] and rotate.
4, use riveting axle [6] to pass the riveted joint of the circular hole on two legs about slotted hole and push pedal [4] on linkage lever [3] other end at last respectively, riveting axle [6] is fixed in the push pedal [4], and linkage lever [3] can be gone up at riveting axle [6] and slide.
