Description

Technical Field

[0001] This utility model belongs to the field of storage cabinet technology, specifically relating to tall storage cabinets. Background Technology

[0002] Existing tall kitchen cabinets typically employ an internal shelving system with upper and lower sliding rails, allowing users to pull the shelves out or push them back into the cabinet for easy access to items. However, this technology suffers from the following problems: due to differences in sliding resistance, manufacturing precision, or assembly errors in the upper and lower sliding rails, their sliding speeds may vary, causing the shelves to wobble back and forth when pulled out or retracted. This wobbling not only affects the user experience but may also reduce the lifespan of the sliding rails and even cause items to tip over or slip off, resulting in a less than ideal user experience. Utility Model Content

[0003] The purpose of this invention is to overcome the problem that existing tall cabinet shelves wobble back and forth when pulled out or retracted due to the asynchronous sliding rail devices on the upper and lower sides. This invention provides a tall storage cabinet with a synchronous transmission mechanism between the top sliding guide device and the bottom sliding guide device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A tall storage cabinet includes a cabinet body, a shelf, a top sliding guide device, a bottom sliding guide device, and a synchronous transmission mechanism. The cabinet body has a cabinet cavity with a side opening. The shelf is slidably placed in the cabinet cavity and includes a vertical connecting rod and shelves mounted on the vertical connecting rod. The top sliding guide device includes a first fixed frame connected inside the cabinet cavity and a first sliding frame connected to the upper end of the shelf, the first fixed frame and the first sliding frame being slidably connected by a first slide rail device. The bottom sliding guide device includes a second fixed frame connected inside the cabinet cavity and a second sliding frame connected to the lower end of the shelf, the second fixed frame and the second sliding frame being slidably connected by a second slide rail device. The synchronous transmission mechanism includes a linkage mechanism. The linkage rod consists of a rod, a first rack located in a first fixed frame, a second rack located in a second fixed frame, and a first gear and a second gear located at both ends of the linkage rod. The upper part of the linkage rod is connected to the first fixed frame via a first rotating support structure, and the lower part of the linkage rod is connected to the second fixed frame via a second rotating support structure. The first gear meshes with the first rack, and the second gear meshes with the second rack. When the shelf is pulled out or reset relative to the cabinet, the first gear at the upper end of the linkage rod meshes with the first rack, and the second gear at the lower end of the linkage rod meshes with the second rack, thereby causing the top sliding guide device and the bottom sliding guide device to extend or retract synchronously during the sliding process of the shelf.

[0006] Compared with existing technologies, the storage cabinet of this invention, by setting a synchronous transmission mechanism between the top and bottom sliding guide devices of the storage cabinet, utilizes the meshing transmission of the first gear and the first rack at both ends of the linkage rod, as well as the meshing transmission of the second gear and the second rack, to ensure that the top and bottom sliding guide devices move synchronously when the shelf is pulled out or retracted. This effectively eliminates the problem of back-and-forth swaying of the shelf caused by the difference in sliding speed, improving the stability and smoothness of operation. At the same time, the synchronous transmission mechanism reduces the risk of uneven wear and jamming of the slide rails, extends their service life, and reduces the possibility of items tipping over or slipping, significantly improving the user experience.

[0007] Furthermore, the first fixed frame has a long, narrow clearance hole arranged along the sliding direction of the shelf in the middle, and the upper end of the linkage rod is placed in the clearance hole; the first rack is located on one side of the clearance hole, and the first slide rail device is located on the other side of the clearance hole, with the width of the first slide rail device arranged horizontally; by setting it in this way, the long, narrow clearance hole in the middle of the first fixed frame accommodates the upper end of the linkage rod, and the first rack and the first slide rail device are placed on both sides of the clearance hole with the slide rail width arranged horizontally, which not only ensures the smooth operation of the synchronous transmission mechanism, but also optimizes the spatial layout of the top sliding guide device, and enhances the structural compactness and motion stability.

[0008] Furthermore, a guide pulley is provided on the outer side of the first fixed frame near the first rack, and the first fixed frame abuts against the first sliding frame through the guide pulley. By adding a guide pulley on the outer side of the first fixed frame near the first rack, and making it abut against the first sliding frame, sliding friction is effectively reduced and the guiding stability of the shelf during movement is enhanced, thereby further improving the smoothness of operation and reducing the risk of shaking.

[0009] Furthermore, the first sliding frame is mounted on the upper end of the vertical connecting rod, and the first sliding frame has an open first sliding cavity on the side near the first fixed frame. The first fixed frame is placed in the first sliding cavity through a first sliding device. The shelf includes a top shelf at the top of the vertical connecting rod, a middle shelf in the middle, and a bottom shelf at the bottom. A support frame is provided at the top of the first sliding frame, and the bottom of the top shelf is connected to the upper side of the support frame. With this arrangement, by providing an open first sliding cavity in the first sliding frame to accommodate the first fixed frame, and adding a support frame at the top to fix the top shelf, the connection structure between the shelf and the sliding guide device is optimized, the overall rigidity and load-bearing stability are enhanced, and the shelf layout is ensured to be reasonable, improving the practicality and durability of the storage space.

[0010] Furthermore, the second sliding frame is connected to the lower end of the vertical connecting rod. The second sliding frame has an open second sliding cavity on the side near the second fixed frame. Two second slide rail devices are provided and are located on both sides of the second fixed frame respectively. The second fixed frame is provided with a damper for buffering the second sliding frame when it is reset. The second rack is located on the side of the damper. With this configuration, by setting a double-sided slide rail structure on the second sliding frame and adding a damper buffer device, and integrating the second rack into the side of the damper, the stability and shock absorption effect when the bottom of the shelf slides are effectively enhanced, the impact noise is reduced, the service life is extended, and the accuracy and reliability of synchronous transmission are ensured.

[0011] Furthermore, the first rotating support structure includes a first sliding sleeve disposed on the first sliding frame, and the upper end of the linkage rod is rotatably placed inside the first sliding sleeve; the second rotating support structure includes a second sliding sleeve disposed on the second sliding frame, and the lower end of the linkage rod is rotatably placed inside the second sliding sleeve; a clearance groove arranged vertically is provided on the rear side of the vertical connecting rod, and the linkage rod is placed in the clearance groove; by setting the sliding sleeve structure on the first sliding frame and the second sliding frame to allow the two ends of the linkage rod to be rotatably supported, and providing a clearance groove on the rear side of the vertical connecting rod to accommodate the linkage rod, the installation layout of the synchronous transmission mechanism is optimized, ensuring that the linkage rod rotates smoothly and does not interfere with the shelf structure, thereby improving the overall stability and reliability of operation.
