Description

Technical Field

[0001] The present invention relates to the technical field of drawers, in particular to a linkage drawer load-bearing adjustment system. Background Art

[0002] A kitchen drawer plate rack is a metal storage device installed inside a drawer, primarily used for orderly storing plates, bowls, and other dishes. Made from high-strength steel wire through welding and polishing processes, it can be installed either fixed or pull-out within the drawer. This rack fully utilizes the vertical space in the drawer, allowing plates to be placed upright or tilted, reducing stacking and increasing accessibility. It's commonly used in home kitchens and restaurant kitchens, providing a practical tool for optimizing plate storage and saving space.

[0003] Existing wire racks are mostly made of a single-specification metal wire welded inside a drawer. The gravity of the stored plates will concentrate on the welding points and load-bearing beams of the wire rack. As the use time accumulates, metal fatigue gradually becomes prominent, the welding points are prone to cracking, the steel wire is prone to deformation, and in severe cases, it will directly break. This not only causes the wire rack to lose its storage function, but also causes the stacked plates to lose support and fall over and collide, causing the plates to break. At the same time, the wire rack is fixed inside the drawer. When you need to take out the plates, you need to lean over and search deep inside the drawer, which greatly limits the operational flexibility. To this end, we propose a linked drawer load-bearing adjustment system. Summary of the Invention

[0004] The object of the present invention is to provide a linkage drawer load-bearing adjustment system to solve the problems raised in the above background technology.

[0007] The transmission mechanism includes a rack fixedly connected to the side wall of the cabinet cavity, the surface of the rack is meshed with a gear, the bottom end of the gear is fixedly connected to a screw, and the threaded surface of the screw is threadedly sleeved with a sliding plate.

[0008] The sliding plate is used to drive the storage mechanism to move in the height direction.

[0009] The storage mechanism includes a wire rack located inside the drawer body, a support block is fixedly connected to the bottom surface of the inner cavity of the drawer body, and limiting grooves are provided on both side wall panels of the drawer body. The surface of the sliding plate is slidably connected to the groove wall of the limiting groove, and the side wall panel of the sliding plate away from the screw rod is fixedly connected to the wall panel of the wire rack.

[0010] Preferably, both ends of a side wall panel of the drawer body close to the cabinet are fixedly connected with a first spring sheet.

[0011] When the storage mechanism moves to a specified height position, a portion of the storage mechanism is in contact with the first spring piece.

[0012] The two ends of the side wall of the drawer body away from the cabinet are fixedly connected with a second spring piece.

[0013] When the storage mechanism moves to another specified height position, a portion of the storage mechanism is in contact with the second spring piece.

[0014] Preferably, the bottom end of the screw rod is rotatably connected to the first sliding block, the bottom surface of the inner cavity of the cabinet is fixedly connected to the first slide groove, the surface of the first sliding block is slidably connected in the first slide groove, the top end of the gear is fixedly connected to a round rod, the top end of the round rod is rotatably connected to the second sliding block, the top surface of the inner cavity of the cabinet is fixedly connected to the second slide groove, and the surface of the second sliding block is slidably connected in the second slide groove.

[0015] Preferably, a triangular reinforcement rod is fixedly connected to the bottom surface of the sliding plate, and the other two ends of the triangular reinforcement rod are respectively fixedly connected to two wall panels at the corners of the wire rack.

[0016] Preferably, the storage mechanism also includes fixed blocks fixedly connected to the four corners of the inner cavity of the wire rack, and the first spring sheet is fixedly connected to a first abutment rod at one end close to the wire rack in the height direction. When the wire rack moves to a specified height position, the top end of the fixed block abuts against the bottom end of the first abutment rod.

[0017] Preferably, the second spring sheet is fixedly connected to a second abutting rod at one end close to the wire rack in the height direction, and when the wire rack moves to another specified height position, the bottom end of the fixed block abuts against the top end of the second abutting rod.

[0018] Preferably, a plurality of drainage grooves are formed through the bottom wall panel of the drawer body, and the groove walls of the plurality of drainage grooves are all formed with rounded corners.

[0019] Preferably, the bottom surface of the inner cavity of the cabinet is also fixedly connected to two third sliding grooves, the inner cavities of the two third sliding grooves are slidably connected to third sliding blocks, and the top surfaces of the two third sliding blocks are fixedly connected to the bottom surface of the drawer body.

[0021] Beneficial effects of the present invention:

[0022] When the drawer body is pulled out, the screw rod is driven in the opposite direction to rotate, thereby driving the sliding plate to slide upward, and the sliding plate can be driven to rise by sliding the sliding plate upward, thereby facilitating the removal of the plate from the drawer body.

[0023] When the drawer body is pulled outward, the sliding plate will gradually rise and drive the wire rack to rise. When the fixed block on the wire rack contacts and abuts the first abutment rod, the first abutment rod rises and pushes the first spring piece to deform, which can reduce the sliding speed of the drawer body when it is about to be fully opened. By utilizing the deformation of the first spring piece and the second spring piece to reduce the terminal speed of closing or opening the drawer body, it can be avoided that the drawer body is generated by too much impulse during movement, which causes the dining plate to shake and collide with the support block or the wire rack and be damaged, thereby enhancing the practicality of the device.

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0033] like Figure 1 - Figure 6The drawer body 1 is provided with a plurality of locking plates 32, and the locking plates 33 are provided with a plurality of locking plates 34. The locking plates 33 are provided with a plurality of locking plates 36. The locking plates 33 are provided with a plurality of locking plates 37. The top end of the screw rod 33 is rotatably connected to the first sliding block 35, and the bottom surface of the inner cavity of the cabinet 2 is fixedly connected to the first slide groove 36. The surface of the first sliding block 35 is slidably connected in the first slide groove 36. The top end of the gear 32 is fixedly connected to the round rod 37, and the top end of the round rod 37 is rotatably connected to the second sliding block 38. The top surface of the inner cavity of the cabinet 2 is fixedly connected to the second slide groove 39. The surface of the second sliding block 38 is slidably connected in the second slide groove 39. The bottom surface of the inner cavity of the cabinet 2 is also fixedly connected to two third slide grooves 9. The inner cavities of the two third slide grooves 9 are slidably connected to the third sliding blocks 8. The top surfaces of the two third sliding blocks 8 are jointly fixedly connected to the bottom surface of the drawer body 1, and one side wall panel of the drawer body 1 is fixedly connected to the handle.

[0034] In the specific implementation, by pushing the drawer body 1 to move into the cabinet body 2, the third slide groove 9 slides in the third sliding block 8, driving the gears 32 on both sides of the inner cavity of the cabinet body 2 to rotate on the rack 31, and the gear 32 rotates the screw rod 33 under the transmission gear 32 to rotate, and the sliding plate 34 is driven to move downward by the rotation of the screw rod 33, and the wire rack 41 is driven to move downward by the downward movement of the sliding plate 34, thereby driving the wire rack 41 to move downward, allowing the bottom of the dinner plate in the dinner plate 41 to contact the top surface of the support block 42, so that the gravity of the dinner plate on the dinner plate 41 can be transmitted to the cabinet body 2 through the drawer body 1, reducing the load-bearing capacity of the dinner plate 41, which is beneficial to extending the service life of the dinner plate 41 and avoiding damage to the dinner plate 41.

[0035] As a technical optimization solution of the present invention, the bottom surface of the sliding plate 34 is fixedly connected to a triangular reinforcement rod 401, and the other two ends of the triangular reinforcement rod 401 are respectively fixedly connected to the two wall panels at the corners of the wire rack 41. The storage mechanism 4 also includes a fixed block 44 fixedly connected to the four corners of the inner cavity of the wire rack 41. The first spring sheet 46 is fixedly connected to the first abutment rod 45 at one end close to the wire rack 41 in the height direction. When the wire rack 41 moves to a specified height position, the top end of the fixed block 44 abuts against the bottom end of the first abutment rod 45. The second spring sheet 48 is fixedly connected to the second abutment rod 47 at one end close to the wire rack 41 in the height direction. When the wire rack 41 moves to another specified height position, the bottom end of the fixed block 44 abuts against the top end of the second abutment rod 47.

[0036] It should be noted that the deformation range of the second spring piece 48 is greater than that of the first spring piece 46. When the wire rack 41 rises, the rebound of the second spring piece 48 can generate a thrust on the wire rack 41, which is beneficial to reduce the pulling force when the drawer body 1 is pulled out, making it convenient to use.

[0037] In a specific implementation, when the drawer body 1 moves outward, the gear 32 rotates in the opposite direction to drive the screw rod 33 to rotate in the opposite direction, thereby driving the sliding plate 34 to slide upward. The upward sliding of the sliding plate 34 can drive the wire rack 41 to rise, thereby making it easier to take out the dinner plate in the wire rack 41 and making it easier to use.

[0038] When the drawer body 1 is pushed into the cabinet 2, the sliding plate 34 will gradually descend and drive the wire rack 41 to move downward. When the wire rack 41 is about to descend and contact the support block 42, the fixed block 44 of the drawer body 1 near the handle will contact and abut the second abutting rod 47. The second abutting rod 47 squeezes the second spring piece 48 to deform, thereby reducing the sliding speed of the drawer body 1 when it is about to be fully closed. When the drawer body 1 is pulled outward, the sliding plate 34 will gradually rise and drive the wire rack 41 to rise. When the fixed block 44 on the wire rack 41 contacts and abuts the first abutting rod 45, the first abutting rod 45 rises and pushes the first spring piece 46 to deform, thereby reducing the sliding speed of the drawer body 1 when it is about to be fully opened. By utilizing the deformation of the first spring piece 46 and the second spring piece 48 to reduce the terminal speed of closing or opening the drawer body 1, it is possible to avoid excessive momentum generated by the drawer body 1 during movement, which may cause the dining plate to shake and collide with the wire rack 41 or the support block 42 and be damaged, thereby enhancing the practicality of the device.

[0039] As a technical optimization solution of the present invention, a plurality of drainage grooves 49 are provided through the bottom wall panel of the drawer body 1, and the groove walls of the plurality of drainage grooves 49 are provided with rounded corners. The wall panels on both sides of the cabinet body 2 are provided with snap-in grooves 5, and the inner cavities of the two snap-in grooves 5 are fixedly connected with the first magnet 6. The two ends of the wall panel on the side of the drawer body 1 away from the cabinet body 2 are fixedly connected with the second magnet 7, and the two second magnets 7 are magnetically attracted to the two first magnets 6 respectively.

[0040] In a specific implementation, the water stains on the surface of the dinner plate can be drained away by utilizing the drainage groove 49;

[0041] By pushing the drawer body 1 to move, when the first magnet 6 and the second magnet 7 come into contact and are magnetically attracted, the drawer body 1 is closed.

[0042] When the present invention is in use, by pushing the drawer body 1 to move into the cabinet body 2, the third slide groove 9 slides in the third sliding block 8, driving the gears 32 on both sides of the inner cavity of the cabinet body 2 to rotate on the rack 31, and the gear 32 rotates the screw rod 33 under the transmission gear 32 to rotate, and the sliding plate 34 is driven to move downward by the rotation of the screw rod 33, and the wire rack 41 is driven to move downward by the downward movement of the sliding plate 34, thereby driving the wire rack 41 to move downward, so that the bottom of the dining plate in the wire rack 41 contacts the top surface of the support block 42, so that the gravity of the dining plate on the wire rack 41 is transmitted to the cabinet body 2 through the drawer body 1, thereby reducing the load-bearing capacity of the wire rack 41, and when the first magnet 6 and the second magnet 7 are in contact and magnetically attracted, the drawer body 1 is closed;

[0043] When it is necessary to take out the dinner plate, when the drawer body 1 is pulled outward, the gear 32 rotates in the opposite direction to drive the screw rod 33 to rotate in the opposite direction, thereby driving the sliding plate 34 to slide upward. The upward sliding of the sliding plate 34 can drive the wire rack 41 to rise, and the dinner plate is moved out of the cabinet body 2, so that the dinner plate in the wire rack 41 can be taken out.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and modifications fall within the scope of the invention as claimed.
