Abstract

The invention provides a lever type drawer lock capable of being locked and unlocked without a key. A symmetrical flexible lever mechanism is formed by a support, a spring bolt, a flexible lever, a handle, a compression spring, a guide column, a rivet shaft, a guide wheel, a box cover, a retainer ring and a screw. The lever type drawer lock is mainly characterized in that the flexible lever is formed through a steel wire rope, so that rotation around a shaft is converted into rotation along another shaft; when the handle is rotated clockwise or anti-clockwise by hand, the steel wire rope can be driven to be wound on the cylindrical face of the handle, at the moment, the steel wire rope is like the flexible lever rotating with the center of the handle as a supporting point to shorten the length of the steel wire rope and pull the spring bolt to move downwards along an upper sliding groove of the support to be away from a lock hole, namely the lock is opened, and the handle is pulled to pull out the drawer. Vise versa, the drawer can be locked. The lever type drawer lock capable of being locked and unlocked without the key can be utilized by furniture designed with drawers, the drawers can be locked and unlocked without keys, and the lever type drawer lock can be exchanged with a standard drawer lock.

Description

Lever type drawer lock

Technical field

The present invention relates to a kind of exempting from and can carry out locking and the lever type drawer lock of drawing-out type drawer is determined mechanism with key, mechanism is mainly by support, dead bolt, flexible lever (wire rope), handle, stage clip, guide pillar, riveting axle, directive wheel, lid, back-up ring and a symmetrical flexible leverage of screw formation.

Background technology

Drawer is one of article of storing in people's daily life, it can fill lock, also can not fill lock, as the drawer using on car, ship, when car and boat jolt, drawer just must be used lockset, at present, known drawer-lock great majority utilize key to lock and drawing-out type drawer, and their common features lock exactly or drawing-out type drawer must be used key, open, lock drawer and will increase time and operation link, keeping key is also burden, if key loss, the trouble of bringing is just larger.Drawer-lock is various in style, its principle is also different, although for example Chinese utility model patent manual CN2296909Y has designed a kind of keying automatic window lock that does not use key, this lockset utilizes lever principle to produce one and opens with make dead bolt by the contrary power of force direction, because its structure space is larger, in actual product, be not yet widely used.

Summary of the invention

In order to solve the locking of existing locking mechanism or drawing-out type drawer, must use the large problem of key and key-free lock lamps structure space, the object of the invention is to provide a kind of without key also lockable and drawing-out type drawer, with market on the standard drawer-lock locking device that can exchange.

The technical solution adopted in the present invention is: support, dead bolt, flexible lever (wire rope), handle, stage clip, guide pillar, riveting axle, directive wheel, lid, back-up ring and screw form a symmetrical flexible leverage, and its basic principle is to pass through core part---wire rope forms a flexible lever and makes to be converted to the movement along another axle around the rotation of an axle.

Support and dead bolt form by steel plate milling system, dead bolt can slide on support, flexible lever is exactly wire rope, during tension, can be used as steel pole, handle is formed by rod iron car system, can rotate around drawer panel lockhole, also can push-and-pull drawer, dead bolt upper end is designed to wedge shape, under stage clip effect, be in all the time a high position, when advancing drawer, dead bolt inclined-plane is subject to horizontal thrust, two component that thrust is decomposed into parallel-slope upwards and vertical-horizontal faces down, the vertical-horizontal component that faces down presses dead bolt to make it be reduced to low level downwards, drawer is accessible to be advancing to the position, under the effect of stage clip, dead bolt resets and enters the lockhole on drawer frame, drawer is lockable.During drawing-out type drawer, clockwise or the counter clockwise direction turning handle with hand, drive wirerope-winding on the face of cylinder of handle, now wire rope changes rope capacity as take handle center as the flexible lever that fulcrum rotates, wire rope can shorten and pull dead bolt to leave lockhole downwards, unblank, drawer can be extracted out.

The invention has the beneficial effects as follows:

1. so long as be designed with the furniture of drawer, all can use this locking device;

2. without key, be lockable and drawing-out type drawer;

3. can exchange with standard drawer-lock.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the present invention is further described.

The specific embodiment

In Fig. 1:

1, respectively the small end of two guide pillars [6] be pressed in the corresponding aperture on dead bolt [2] and rivet tightly, the two ends of flexible lever (wire rope) [3] are separately fixed in two side channels on dead bolt [2] with two screws [11].

2, respectively two riveting axles [7] are inserted in the hole of directive wheel [8] again, the small end of riveting axle [7] is pressed in the corresponding aperture on support [1] and is riveted tightly.

3, two stage clips [5] are inserted in respectively on two guide pillars [6] of riveting tightly on dead bolt [2], pack into together again on support [1], straight trough on dead bolt [2] is matched with the T-shape slide rail of support [1] projection, and two guide pillars [6] on dead bolt [2] are embedded in " U " type groove on support [1], make stage clip [5] in the upper surface of " U " type groove; Inwardly press dead bolt [2], the flexible lever (wire rope) [3] on it is embedded in the groove of two directive wheels [8], so far form a lock body.

4, the round buss on lock body upper bracket [1] is inserted in the hole of panel from drawer panel inner side.

5, handle [4] is passed to the round buss lock body upper bracket [1] from drawer panel outside, then back-up ring [10] is sticked in the draw-in groove of handle [4], and flexible lever (wire rope) [3] is embedded in the end face groove on handle [4].
