Description
Technical Field
[0001] This utility model relates to the field of cabinets, and more particularly to a cabinet pull-out storage device with a synchronous structure. Background Technology
[0002] Storage is an indispensable part of modern home decoration, used in various areas such as kitchen storage, walk-in closet storage, stairwell storage, and entryway storage. To avoid cluttered storage of kitchen utensils, clothes, shoes, and other items, more and more families are using high-specification custom-made storage devices to neatly and orderly store these items.
[0003] Objectively speaking, a pull-out basket consists of three parts: the basket body, the upper slide rail, and the lower slide rail. The basket body connects to the upper and lower slide rails and is also connected to the cabinet door. The upper and lower slide rails are fixed to the upper and lower ends of the cabinet body, respectively. When using the basket, pulling out the cabinet door causes the basket body and door to slide out along the upper and lower slide rails, making it easy to retrieve items from the basket. However, due to structural design and installation errors, the upper and lower slide rails may not slide out synchronously, and the basket body may not rotate and may be loose and wobble significantly, affecting normal use and providing a poor user experience.
[0004] Therefore, it is necessary to provide a cabinet pull-out storage device with a synchronization structure to solve the above-mentioned technical problems. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a cabinet pull-out storage device with a synchronous structure.
[0006] This utility model provides a cabinet pull-out storage device with a synchronous structure, including an upper slide rail assembly and a lower slide rail assembly for installation inside the cabinet body. A connecting rod is installed between the upper slide rail assembly and the lower slide rail assembly to enable synchronous sliding of the upper slide rail assembly and the lower slide rail assembly. A shelf is rotatably connected between the upper slide rail assembly and the lower slide rail assembly.
[0007] Preferably, the shelf is equipped with a door panel mounting bracket and a storage basket.
[0008] Preferably, the shelf includes an upper U-shaped frame, a lower U-shaped frame, and an inner aluminum profile tube connecting the upper and lower U-shaped frames. Both the upper and lower U-shaped frames are assembled from outer aluminum profile tubes and corner brackets, with the ends of the inner aluminum profile tubes inserted into the corresponding outer aluminum profile tubes. End caps are installed at the ends of both the upper and lower U-shaped frames, and corner caps are installed on the corner brackets. Positioning turntables are fixed to both the upper and lower U-shaped frames, and mounting plates are rotatably connected to the positioning turntables. These mounting plates are connected to corresponding upper and lower slide rail assemblies. The height of the shelf is adjustable to accommodate cabinets of different heights.
[0009] Preferably, the positioning turntable includes a rotating seat fixedly connected to the outer tube of the aluminum profile, a fixed seat rotatably connected to the rotating seat via a bearing, spring positioning beads installed at equal angles in the fixed seat, a positioning groove that cooperates with the spring positioning beads on the rotating seat, and an anti-dislodgement cap installed in the fixed seat to prevent the bearing from moving out.
[0010] When the shelf is fully extended or in the desired position, the user can rotate the entire shelf.
[0011] Rotation occurs at the positioning turntable. The fixed seat is secured to the mounting plate, which in turn is fixed to the three main sections of the slide rail, i.e., the moving parts of the slide rail. The rotating seat is fixed to the aluminum profile outer tube of the shelf. Low-friction rotation is achieved between the two via bearings.
[0012] When rotating, the spring positioning ball fixed on the fixed seat will engage with the positioning groove on the rotating seat, providing a clear sense of position and a stop function to prevent random rotation.
[0013] Preferably, both the upper slide rail assembly and the lower slide rail assembly include a base plate and a side plate symmetrically fixed on both sides of the base plate. Two side plates are slidably connected to the inner side of each side plate, and three main sections are slidably connected to the inner sides of the two side plates. A rack is fixed to the top of the base plate. A rotating shaft is rotatably connected to each of the three main sections via a flange bearing. One end of the rotating shaft is fixedly connected to a gear that meshes with the rack. A connecting rod is installed between the two rotating shafts. The rotating shaft inside the slide rail assembly drives the gear to rotate.
[0014] The gear meshes with a rack fixed to the base plate. When the slide rail is pulled out, the gear rolls on the rack, driving the shaft to rotate. A connecting rod rigidly connects the shafts of the upper and lower slide rail assemblies, forcing the two shafts to rotate synchronously. The synchronous rotation of the shafts causes the upper and lower gears to roll synchronously on their respective racks, thus achieving completely synchronous extension and retraction of the upper and lower slide rail assemblies.
[0015] Preferably, pulley blocks are installed on the inner sides of both the first and second side plates, and linear guide rails that are slidably connected to the pulley blocks are fixed on both sides of the third main section and on the outer sides of the second side plates. The pulley blocks roll on the linear guide rails, providing a smooth sliding experience and load-bearing capacity.
[0016] Preferably, the connecting rod includes two connecting outer tubes, two outer tube seats, two locking knobs, and a connecting inner tube. One end of the connecting outer tube is fixedly connected to the rotating shaft, and the other end of the connecting outer tube is fixed with an outer tube seat. A locking knob is threaded onto the outer tube seat, and both ends of the connecting inner tube are installed inside the connecting outer tube along the locking knobs and the outer tube seats.
[0017] The connecting rod consists of an outer connecting tube, an inner connecting tube, an outer tube seat, and a locking knob.
[0018] By loosening the locking knob, the depth to which the inner connecting tube is inserted into the outer connecting tube can be adjusted, thereby changing the total length of the connecting rod.
[0019] After adjusting, tighten the locking knob to lock the connecting rod to the required length, adapting to cabinets of different heights.
[0020] Compared with related technologies, the present invention provides the following beneficial effects: This invention is a structurally stable, robust, and durable pull-out basket with synchronized sliding, which solves the problems of wobbling and loosening and allows for left and right rotation. Compared with conventional designs, the upper and lower slide rail bases of the basket adopt existing and very mature ball-bearing telescopic slide rails. The base is fixed with an anti-sway rack and the support plate for fixing the basket body has a gear mechanism. The upper and lower slide rails are connected by a quick-connect synchronous rod, providing consumers with an excellent consumer experience. Attached Figure Description

Detailed Implementation
[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0024] Please refer to the following: Figures 1 to 6A cabinet-type pull-out storage device with a synchronous structure is disclosed. The device includes an upper slide rail assembly 03 and a lower slide rail assembly 04 for installation inside the cabinet. A connecting rod 05 is installed between the upper slide rail assembly 03 and the lower slide rail assembly 04, which enables the upper slide rail assembly 03 and the lower slide rail assembly 04 to slide synchronously. Simultaneously, a shelf 06 is rotatably connected between the upper slide rail assembly 03 and the lower slide rail assembly 04. Users can fully pull out or rotate the shelf 06 to a suitable position according to actual needs for convenient access to items.
[0025] The shelf 06 is equipped with a door panel mounting bracket 01 and a storage basket 02. The door panel mounting bracket 01 can be used to install cabinet doors, making the storage device neater and more aesthetically pleasing when closed; the storage basket 02 provides ample storage space, making it convenient for users to categorize and store items.
[0026] The shelf 06 includes an upper U-shaped frame, a lower U-shaped frame, and an inner aluminum profile tube 13 connecting the two. Both the upper and lower U-shaped frames are assembled from outer aluminum profile tubes 11 and corner brackets 10, a method that not only ensures structural stability but also facilitates assembly and disassembly. The ends of the inner aluminum profile tubes 13 are inserted into the corresponding outer aluminum profile tubes 11, further enhancing the overall strength of the shelf 06. Both the upper and lower U-shaped frames are fitted with end caps 12, and the corner brackets 10 are fitted with corner caps 09, improving the aesthetics and safety of the device. Furthermore, both the upper and lower U-shaped frames are fixed with positioning turntables 08, on which mounting plates 07 are rotatably connected. The mounting plates 07 are connected to corresponding upper slide rail assemblies 03 and lower slide rail assemblies 04, allowing the height of the shelf 06 to be adjusted to accommodate cabinets of different heights.
[0027] The positioning turntable 08 is a key component for realizing the rotation and positioning of the shelf 06. It includes a rotating base 21 fixedly connected to the aluminum profile outer tube 11, and a fixed base 24 rotatably connected to the rotating base 21 via bearings 23. Spring positioning beads 22 are installed at equal angles within the fixed base 24, and the rotating base 21 has positioning grooves that mate with the spring positioning beads 22. When the shelf 06 is fully extended or in the desired position, the user can rotate the entire shelf 06; the rotation occurs at the positioning turntable 08. The fixed base 24 is fixed to the mounting plate 07, which is fixed to the three main sections 31 of the slide rail, i.e., the movable part of the slide rail. The rotating base 21 is fixed to the aluminum profile outer tube 11 of the shelf 06, and the two rotate with low friction via bearings 23, making the rotation process smoother. During rotation, the spring positioning ball 22 fixed on the fixed base 24 engages with the positioning groove on the rotating base 21, providing a clear sense of positioning and a stop function, preventing the shelf 06 from rotating arbitrarily and ensuring its stability during use. Simultaneously, the fixed base 24 is equipped with an anti-dislodgement cap 25 to prevent the bearing 23 from shifting out, further ensuring the normal operation of the positioning turntable 08.
[0028] The upper slide rail assembly 03 and the lower slide rail assembly 04 have the same structure, both including a base plate 26 and a side plate 27 symmetrically fixed on both sides of the base plate 26. Two side plates 30 are slidably connected to the inner side of the side plate 27, and three main sections 31 are slidably connected to the inner side of the two side plates 30. This multi-segment sliding structure allows the slide rail assembly to achieve a long extension stroke, meeting the needs of cabinets of different depths. A rack 15 is fixed to the top of the base plate 26, and a rotating shaft 18 is rotatably connected to the three main sections 31 via a flange bearing 32. One end of the rotating shaft 18 is fixedly connected to a gear 20 that meshes with the rack 15. A connecting rod 05 is installed between the two rotating shafts 18. When the slide rail assembly is pulled out, the rotating shaft 18 inside the slide rail assembly drives the gear 20 to rotate. The gear 20 meshes with the rack 15 fixed on the base plate 26, causing the gear 20 to roll on the rack 15, thereby driving the rotating shaft 18 to rotate. The connecting rod 05 rigidly connects the rotating shafts 18 of the upper and lower slide rail assemblies, forcing the two rotating shafts 18 to rotate synchronously. The synchronous rotation of the rotating shafts 18 causes the upper and lower gears 20 to roll synchronously on their respective racks 15, thereby achieving completely synchronous extension and retraction of the upper slide rail assembly 03 and the lower slide rail assembly 04, ensuring the stability of the shelf 06 during the pulling process.
[0029] To provide a smooth sliding experience and sufficient load-bearing capacity, pulley blocks 28 are installed on the inner sides of the first side plate 27 and the second side plate 30. Linear guide rails 29, which are slidably connected to the pulley blocks 28, are fixed on both sides of the third main section 31 and the outer side of the second side plate 30. The pulley blocks 28 roll on the linear guide rails 29, reducing friction during sliding and making the extension and retraction of the slide rail assembly easier and more free.
[0030] The connecting rod 05 is a key connecting component for the synchronous sliding of the upper slide rail assembly 03 and the lower slide rail assembly 04. It also features length adjustment to accommodate cabinets of different heights. The connecting rod 05 consists of two outer connecting tubes 33, two outer tube seats 34, two locking knobs 35, and an inner connecting tube 36. One end of each outer connecting tube 33 is fixedly connected to the rotating shaft 18, and the other end is fixed to an outer tube seat 34. Locking knobs 35 are threaded onto the outer tube seats 34. The two ends of the inner connecting tube 36 are installed inside the outer connecting tubes 33 along the locking knobs 35 and the outer tube seats 34. By loosening the locking knobs 35, the insertion depth of the inner connecting tube 36 into the outer connecting tube 33 can be adjusted, thereby changing the total length of the connecting rod 05. After adjustment, tightening the locking knobs 35 locks the connecting rod 05 to the desired length, ensuring the stability and reliability of the device after height adjustment.
[0031] This cabinet pull-out storage device with a synchronized structure achieves smooth pulling, synchronized movement, flexible rotation, and height adjustment through the close cooperation and ingenious design of its components, providing users with a more convenient and efficient storage experience.
