Embodiment Construction

[0011] In the attached picture:

[0012] 1. Insert the small end of the lock tongue [2] into the concentric hole on the upper and lower planes of the bracket [1], and at the same time insert the compression spring [5] into the small end of the lock tongue [2] so that the compression spring [5] Insert the washer [9] and collar [10] from the small end of the lock tongue [2] between the inner surface of the "匚"-shaped lower plane of the bracket [1] and the large end face of the lock tongue [2]. , so that the washer [9] and collar [10] are on the outside of the lower plane of the bracket [1] "匚" shape.

[0013] 2. Put the two linkage levers [3] close to one end of the middle round hole, and clamp the round hole plane at the small end of the lock tongue [2] one after the other, so that they have 3 holes (2 long round holes, 1 round hole) Concentric, so that the inclined surface of the inclined surface of the lock tongue [2] is on the same side as the surface with four threaded hol...

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 [0001] The invention relates to a lever-type drawer locking mechanism that can lock and open a drawer without using a key. Constitute a symmetrical lever mechanism. Background technique [0002] At present, most known drawer locks use keys to lock and open the drawers. Their common feature is that a key must be used to lock or open the drawer. This increases the time and operation links for opening and locking the drawer; A burden; even more trouble if the key is lost. Contents of the invention [0003] In order to solve the problem that a key must be used for locking or unlocking the drawer in the existing locking mechanism, the purpose of the present invention is to provide a device that can lock and unlock the drawer without a key. [0004] The technical proposal adopted in the present invention is: support, dead bolt, linkage lever, push plate, clip spring, axle sleeve, riveted shaft, washer and collar etc. constitute a symmetrical lever mechanism. ...
