The utility model provides a drawer locking mechanism.

In the embodiment of the utility model, the drawer locking adjusting mechanism comprises a lock hole 11 arranged on the movable rail 1 and a base 2 fixedly arranged on the drawer, and a lock rod is hinged on the base through an elastic part 4; the handle 32 for stirring is arranged on one side of the lock rod back to the outside of the drawer, the lock rod is further provided with a lock tongue 31 capable of being inserted into the lock hole, one side of the lock tongue facing the outside of the drawer is provided with a locking part which is in a step shape and is mutually abutted against the lock hole, one side of the lock tongue back to the outside of the drawer is inclined or arranged in an arc shape, and the elastic piece drives the lock tongue to be clamped into the lock hole under the action of the elastic piece on the lock rod.

Drawer locking adjustment mechanism, the track subassembly that is equipped with fixed rail and movable rail and constitutes on the cabinet bucket 10 of furniture, the both sides of drawer 20 bottom are then installed drawer locking mechanism, and two drawer locking mechanism bilateral symmetry set up. When the drawer is installed, the drawer is inserted into the drawer along the direction of the movable rail, the lock rod is blocked by the end part of the movable rail to rotate until the lock rod moves to a position opposite to the lock hole on the movable rail, the lock rod rebounds under the action of the elastic piece and drives the lock tongue to be inserted into the lock hole of the movable rail, and the locking part and the lock hole are mutually abutted, so that the drawer is installed on the movable rail; when the drawer needs to be removed, the handle is pressed and the lock rod is driven to rotate, so that the lock tongue on the lock rod is separated from the lock hole on the movable rail, and then the drawer is pulled out outwards. This drawer locking mechanism simple structure and install and remove convenient operation, when the drawer is pulled outward to the back after the drawer installation finishes, the pulling force of applying will drive the locking lever through the base and outwards remove, then the ladder face in the locking lever locking part offsets with the lockhole inner wall on the movable rail, and then drive drawer and movable rail outwards remove, and at this in-process, the locking lever will receive the reaction force that the movable rail brought, this reaction force is the unanimity of the moment of torsion direction and the elastic component that the locking lever brought, thereby can effectively avoid locking lever and lockhole to drop, avoided drawer and movable rail to break away from promptly and drop.

Drawer locking adjustment mechanism, lockhole 11 sets up in the opposite flank department of two movable rails 1, base 2 installs in the drawer bottom, is located the department between two movable rails on the locking lever installation base, this drawer locking mechanism can be hidden better, greatly reduces its maloperation because of accidental collision leads to, also can improve the aesthetic property of drawer. In addition, the locking part of the locking tongue 31 is in a step shape with a plurality of steps, so that the locking tongue can be more conveniently matched and connected with drawers and rail assemblies with different specifications.

Drawer locking mechanism, base 2 includes fixed mounting in the fixing base 21 of drawer bottom, and the regulation seat 22 that removes about the fixing base relatively, be equipped with the adjusting part who drives both relative movement between fixing base and the regulation seat, still be equipped with the fixed fork 23 of the mutual chucking of 1 tip of movable rail on the regulation seat, when installing the drawer to the movable rail, fixed fork is along the movable rail direction card on the movable rail, insert the movable rail lockhole until the spring bolt of locking lever, fixed fork also with the mutual chucking of movable rail, this can effectively improve convenient operation nature. The adjusting assembly comprises an adjusting wheel 5 and a worm-shaped adjusting rod 6 which are rotatably arranged in a fixed seat 21, the end parts of the adjusting wheel and the adjusting rod are provided with bevel gears 7 which are meshed with each other, part of the adjusting wheel penetrates through the bottom surface of the fixed seat, and threads which are meshed with each other are arranged between the adjusting rod and the adjusting seat; if the drawer is installed behind the movable rail, if the transverse position of the drawer is not correct, when the drawer does not correspond to the opening of a cabinet barrel of furniture, or when the positions between different drawers are not level, the part exposed out of the fixed seat on the adjusting wheel can be shifted, the adjusting wheel drives the adjusting rod to rotate through the bevel gear, the adjusting rod is enabled to move relative to the adjusting seat through threads, the fixed seat is driven to move relative to the adjusting seat, the drawer is also driven to move left and right, the drawer is adjusted to a proper position, therefore, the transverse adjustment of the drawer is conveniently and rapidly realized, the drawer adjusting device is small in size and simple in operation, and the adjusting rod can stably and accurately drive the drawer to move through the threads of the worm structure. In addition, the axes of the adjusting wheel 5 and the adjusting rod 6 are arranged perpendicular to each other, and the axial direction of the adjusting wheel is parallel to the moving direction of the movable rail, so that the rotating direction of the adjusting wheel is consistent with the left-right adjusting direction, and the convenience of operation is improved. Still, elastic component 4 is the elastic plate that extends out from adjusting seat 22, when the spring bolt inserts the lockhole of movable rail, leave certain clearance between elastic plate and the handle or only be limited to mutual contact, and when the drawer inserted the in-process of movable rail and need demolish the drawer and rotate the locking lever in order to drive the spring bolt and withdraw from the lockhole, the handle on the locking lever presses to the elastic plate and makes the elastic plate take place to deform, until the spring bolt is relative with the lockhole or the locking lever leaves the movable rail after, the elastic plate drives handle antiport under the effect of resilience force, thereby make the spring bolt insert the lockhole or the drawer demolish the back reset.

The above only be the preferred embodiment of the utility model discloses a not consequently restriction the utility model discloses a patent range, all are in the utility model discloses a conceive, utilize the equivalent structure transform of what the content was done in the description and the attached drawing, or direct/indirect application all is included in other relevant technical field the utility model discloses a patent protection within range.
