For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] This utility model embodiment provides a turntable pull basket with a simple installation structure, which makes the turntable more stable when opening and closing.

[0035] The following is combined with Figures 1-6 The technical solution provided by this utility model will be described in more detail.

[0036] Example 1:

[0037] See Figures 1-6 As shown, the turntable pull-out basket provided by this utility model includes a fixed frame 5, a turntable 4, a first rotating arm 1, a second rotating arm 2, and a third rotating arm 3. The fixed frame 5 is fixed in the installation position. The two ends of the first rotating arm 1 are rotatably connected to the fixed frame 5 and the turntable 4, respectively. The second rotating arm 2 and the third rotating arm 3 are rotatably connected. The other end of the second rotating arm 2 is rotatably connected to the fixed frame 5, and the other end of the third rotating arm 3 is rotatably connected to the turntable 4. A positioning component is fixed on the third rotating arm 3, and a limiting part 6 is fixed on the first rotating arm 1. The positioning component and the limiting part 6 are slidably connected, thereby causing the first rotating arm 1 to pull the third rotating arm 3 and the second rotating arm 2 to rotate, thereby causing the turntable 4 to be pulled open or closed from the installation position.

[0038] As an optional implementation, see Figure 5 As shown, the first rotating arm 1 and the second rotating arm 2 are rotatably connected to the opposite ends of the fixed frame 5. The first rotating arm 1, the second rotating arm 2 and the third rotating arm 3 are all located in the horizontal plane and rotate under the action of external force.

[0039] The fixing bracket 5 is fixed at the corner of the cabinet 100, saving space. The turntable 4 can be installed on only one side through the fixing bracket 5. The installation structure is simple and can effectively improve the convenience of installation.

[0040] The turntable pull basket provided by this utility model, through the cooperation of the first rotating arm 1, the second rotating arm 2 and the third rotating arm 3, when the turntable 4 is pulled or pushed, the first rotating arm 1 rotates, and through the cooperation of the positioning part and the limiting part 6, the second rotating arm 2 and the third rotating arm 3 move synchronously, stably supporting the turntable 4, making the turntable 4 more stable when opening and closing.

[0041] As an optional implementation, see Figure 2 As shown, a limit stop 42 is provided on the peripheral wall of the turntable 4 to prevent items from falling.

[0042] See Figure 5 As shown, the bottom of the turntable 4 is provided with a protrusion 41, and the first rotating arm 1 and the third rotating arm 3 are rotatably connected to the corresponding protrusion 41 to ensure structural strength.

[0043] As an optional implementation, see Figure 3 and Figure 4 As shown, the limiting part 6 includes a limiting shell, and a limiting slide 61 is provided inside the limiting shell. The side of the limiting shell facing the third rotating arm 3 is an open side. The positioning member extends into the limiting slide 61 from the open side and is slidably connected with the limiting slide 61.

[0044] The limiting shell is fixed to the third rotating arm 3, such as by screw locking. The structure of the limiting shell protects the structure of the positioning component, prevents interference between the external structure and the positioning component, and ensures smooth sliding of the positioning component.

[0045] As an optional implementation, see Figure 4 As shown, the limiting slide 61 has a curved structure, and the sidewall of the limiting slide 61 is used to restrict the positioning component from detaching.

[0046] The specific shape of the limiting slide 61 restricts the movement trajectory of the positioning component, thereby limiting the rotation angle between the second rotating arm 2 and the third rotating arm 3. By pulling the positioning component, the limiting slide 61 pulls the second rotating arm 2 and the third rotating arm 3 to rotate, so that when the turntable 4 is pulled, the first rotating arm 1, the second rotating arm 2 and the third rotating arm 3 move simultaneously, which improves the stable support for the turntable 4.

[0047] As an optional implementation, see Figure 4 As shown, a positioning rod 71 is provided on the third rotating arm 3. The positioning component includes a sliding shaft 72. The sliding shaft 72 is fixed to one end of the positioning rod 71 away from the third rotating arm 3. The sliding shaft 72 extends into the limiting slide 61 and slides along the limiting slide 61.

[0048] The sidewall of the limiting slide 61 prevents the sliding shaft 72 from disengaging, ensuring the stability of the structure. This structure ensures that the sliding shaft 72 slides smoothly along the limiting slide 61 when the turntable 4 is pulled or pushed, thereby ensuring the smooth opening and closing of the turntable 4.

[0049] As an optional implementation, see Figure 5 and Figure 6 As shown, the turntable basket also includes a damper 8, and the third rotating arm 3 is connected to the damper 8 via a transmission assembly 9.

[0050] The damper 8 is a mature, existing technology and can be purchased directly from the market. The damper 8 acts as a buffer when the turntable 4 retracts into its mounting position, protecting the turntable 4.

[0051] As an optional implementation, see Figure 5 and Figure 6 As shown, a housing 90 is fixed on the third rotating arm 3, and the damper 8 is located inside the housing 90. The structure of the housing 90 serves to protect the damper 8 and prevent it from being damaged.

[0052] See Figure 5 and Figure 6 As shown, the transmission assembly 9 includes a pull rod 91 and a slider 92. One end of the pull rod 91 is rotatably connected to the third rotating arm 3. A guide rail 901 is provided inside the housing 90. The other end of the pull rod 91 is provided with a shaft 911, which is slidably connected to the guide rail 901. The slider 92 is rotatably connected to the damper 8. A limit groove 921 is provided on the slider 92. The shaft 911 can extend into the limit groove 921. When the turntable 4 is pushed, the slider 92 can drive the damper 8 under the pull of the shaft 911.

[0053] When the turntable 4 is pushed, the third rotating arm 3 rotates, causing the shaft 911 of the pull rod 91 to slide along the guide rail 901 inside the housing 90. The shaft 911 extends into the limiting groove 921. The shaft 911 cooperates with the limiting groove 921, causing the slider 92 to activate the damper 8, so that the damper 8 plays a damping role, preventing the large impact force when the turntable 4 is closed, protecting the turntable 4, and improving the service life of the turntable basket.

[0054] Example 2:

[0055] This embodiment provides a storage cabinet, including a cabinet body 100 and the aforementioned turntable pull-out basket, with a fixing frame 5 fixed to the cabinet body 100.

[0056] This turntable pull-out basket is installed inside the cabinet 100 of the storage cabinet, and is especially suitable for corner positions. It can effectively improve the space utilization of the cabinet 100 and achieve a good storage effect. Moreover, the turntable 4 can be installed on one side via the fixing bracket 5, and the installation structure is simple, which can effectively improve the convenience of installation.

[0057] The turntable pull-out basket can be installed in one or two or more layers on the cabinet 100, which saves space.
