Description

Technical Field

[0001] This application relates to the field of daily necessities technology, and more specifically to a turntable. Background Technology

[0002] Installing multiple shelves within storage spaces is a common way to increase storage capacity, such as in cabinets and refrigerators. Shelves divide the internal storage space into multiple levels, effectively increasing storage capacity and making more efficient use of space, preventing waste. However, this setup limits the height between adjacent shelves, making it inconvenient, especially since users need to remove items from the front to access items from the back, and then put the front items back in their original positions. Currently, rotary tables are often used to organize items within storage spaces. Rotating tables move items from the inside to the outside, making it easier and less strenuous for users to retrieve items. This is particularly suitable for storing items placed in corners or inside cabinets, offering flexibility in use. For example, the utility model patent with authorization announcement number CN219629286U discloses a rotatable, pushable, and pullable storage device, including a base and a storage tray. The base has a strip-shaped hole in the middle, and the bottom of the storage tray has a mounting part that can be rotatably and slidably disposed within the strip-shaped hole. Several ball bearings are mounted on the base, and the lower end face of the storage tray is formed with an inner annular groove and a straight groove for the ball bearings to slide. The straight groove is connected to the inner annular groove, allowing the storage tray to rotate or slide on the base. This technology... The design incorporates a linear sliding groove, allowing for easy access to items placed behind the storage tray by rotating it or by pushing or pulling it. When the tray is inside a refrigerator or cabinet, it can be pulled out for convenient use, extending a short distance from the cabinet or refrigerator for easy retrieval. However, the lack of a limiting structure between the base and the storage tray means it cannot be properly positioned, allowing it to rotate freely inside the refrigerator or cabinet, negatively impacting the user experience. Summary of the Invention

[0003] The technical problem to be solved by this application is to provide a turntable that, through the cooperation of a connecting shaft and a first slide rail, allows the turntable to rotate and slide on the base. By setting a limiting structure, the turntable is locked in the initial state and can only rotate freely in the extended state, making it more reliable and providing a better user experience.

[0004] This application provides a turntable, including a base and a disc body. The bottom of the disc body is provided with a connecting shaft for rotatable connection with the base. The base is provided with a first slide rail for sliding the connecting shaft. The base is provided with a first protrusion and a second protrusion. The bottom of the disc body is provided with a limiting structure, which includes a symmetrically distributed second slide rail and a third slide rail. The first protrusion abuts against the second slide rail, and the second protrusion abuts against the third slide rail to lock the rotation of the disc body. The first protrusion slides along the second slide rail and disengages from the second slide rail, and the second protrusion slides along the third slide rail and disengages from the third slide rail to unlock the rotation of the disc body.

[0005] In this technical solution, the placement of the turntable includes, but is not limited to, the inner cavity of a refrigerator and the inner cavity of a cabinet. When items are placed inside the cavity, items located on the inner side are difficult to remove directly. However, by placing a turntable inside the cavity, items are placed on the turntable's plate. The plate is connected to the base via a connecting shaft, allowing the plate to rotate 360 ​​degrees on the base. Items on the inner side can be rotated to the outer side for easy access. Considering that some cavities are quite deep, even after rotating the plate, there is still a long distance to reach the item. This solution includes a first slide rail on the base, with the connecting shaft installed inside. The plate, under force, can slide along the first slide rail to extend or retract, allowing the user to push and pull the plate, meeting more usage needs. By providing a first protrusion and a second protrusion on the base, and a limiting structure at the bottom of the plate, the first protrusion... The second protrusion abuts against the second slide rail and the third slide rail, thereby limiting the left and right sides of the tray. This prevents the tray from rotating relative to the base in the initial state. The initial state mentioned in this application refers to the tray being horizontally positioned relative to the base and not rotating. When the connecting shaft slides along the first slide rail until the tray is in the extended state relative to the base, the tray drives the limiting structure to slide synchronously. This causes the first protrusion to slide along the second slide rail and disengage from it, and the second protrusion to slide along the third slide rail and disengage from it. This allows the tray to rotate and unlock, enabling it to rotate 360 ​​degrees on the base. Through the cooperation of this limiting structure with the first and second protrusions, the tray is locked in rotation in the initial state. The tray can only rotate freely in the extended state, preventing it from rotating randomly inside the refrigerator and cabinet cavities and affecting storage. This makes the use more reliable and provides a better user experience.

[0006] As an improvement, the limiting structure includes a first arc-shaped slide rail and a second arc-shaped slide rail. The first arc-shaped slide rail is located on one side of the second slide rail and is used to guide the rotation of the first protrusion. The second arc-shaped slide rail is located on one side of the third slide rail and is used to guide the rotation of the second protrusion. In this technical solution, when the connecting shaft slides along the first slide rail until the disc body is in an extended state relative to the base, the disc body can rotate 360 ​​degrees around the connecting shaft. The first protrusion slides out of the second slide rail, and the second protrusion slides out of the third slide rail. The radius of rotation is between the first protrusion and the connecting shaft, and between the second protrusion and the connecting shaft. When the disc body rotates, the first protrusion can slide along the first arc-shaped slide rail, or the first protrusion can slide along the second arc-shaped slide rail, or the second protrusion can slide along the first arc-shaped slide rail, or the second protrusion can slide along the second arc-shaped slide rail, thereby assisting the rotation of the disc body, improving the rotation efficiency of the disc body, and preventing the disc body from deviating during rotation.

[0007] As an improvement, the first arc-shaped slide rail is joined end-to-end with the second slide rail, and the second arc-shaped slide rail is joined end-to-end with the third slide rail. In this technical solution, one end of the first arc-shaped slide rail is joined to one end of the second slide rail, and the other end of the first arc-shaped slide rail is joined to the other end of the second slide rail, to extend the sliding guide path of the first arc-shaped slide rail to the first or second protrusion as much as possible, making the sliding more efficient and reliable. Similarly, one end of the second arc-shaped slide rail is joined to one end of the third slide rail, and the other end of the second arc-shaped slide rail is joined to the other end of the third slide rail, to extend the sliding guide path of the second arc-shaped slide rail to the first or second protrusion as much as possible, making the sliding more efficient and reliable.

[0008] As an improvement, the first slide rail is provided with a locking position and an unlocking position. The connecting shaft slides along the first slide rail to switch between the locking and unlocking positions. When the connecting shaft is in the locking position, the disc body is in the initial state relative to the base. The first protrusion abuts against the second slide rail, and the second protrusion abuts against the third slide rail to lock the rotation of the disc body. When the connecting shaft is in the unlocking position, the disc body is in the extended state relative to the base. The first protrusion disengages from the second slide rail, and the second protrusion disengages from the third slide rail to unlock the rotation of the disc body. In this technical solution, a locking position and an unlocking position are set on the first slide rail. By pushing and pulling the disc, the connecting shaft slides within the first slide rail to switch between the locking and unlocking positions. When the connecting shaft slides along the first slide rail to the locking position, the disc is in the initial state relative to the base. At this time, the first protrusion abuts against the second slide rail, and the second protrusion abuts against the third slide rail in the horizontal direction, thereby locking the disc by rotation. The disc cannot rotate on the base. When the connecting shaft slides along the first slide rail to the unlocking position, the disc is in the extended state relative to the base. The disc drives the limiting structure to slide, causing the first protrusion to slide away from the second slide rail, and the second protrusion to slide away from the third slide rail, thereby unlocking the disc by rotation. The disc can rotate 360 ​​degrees on the base, realizing that the disc is locked by rotation in the initial state, and the disc can only rotate freely in the extended state, making it more reliable and providing a better user experience.

[0009] As an improvement, the base is symmetrically provided with a third protrusion and a fourth protrusion, and the first protrusion, second protrusion, third protrusion and fourth protrusion are arranged in a rectangular distribution; the third protrusion and the fourth protrusion are flush with the unlocking position. In this technical solution, by adding a third and fourth protrusion, the rotation limit of the disc body in the initial state is made more reliable, preventing the disc body from shaking on the base and improving stability. On the other hand, considering that the internal cavity of refrigerators and cabinets is roughly rectangular with limited height and large depth, the disc body and base in this application are roughly rectangular in structure to adapt to such rectangular internal cavities. Compared with a circular turntable, it can accommodate more items. The first, second, third, and fourth protrusions of the ball bearing assembly are rectangularly distributed, which is more suitable for the rotation of the rectangular disc body. When the connecting shaft is in the locked position, the first and third protrusions abut against the second slide rail, and the second and fourth protrusions abut against the third slide rail. Each protrusion abuts against the limiting structure in the horizontal direction, so that the disc body is limited on the base and cannot rotate. The first and third protrusions can only move along the second slide rail. The slide rail slides back and forth, and the second and fourth protrusions can only slide back and forth along the third slide rail. When the connecting shaft is in the unlocked position, the second slide rail slides outward relative to the first and third protrusions, and the third slide rail slides outward relative to the second and fourth protrusions, causing the disc to slide outward relative to the base. At this time, the first protrusion disengages from the second slide rail, and the third protrusion abuts against the second slide rail; the second protrusion disengages from the third slide rail, and the fourth protrusion abuts against the third slide rail, allowing the disc to rotate 360 ​​degrees on the base. The disc can only rotate freely in the extended state. The structure is ingeniously designed and simple and reliable to use. On the other hand, the third and fourth protrusions are both flush with the unlocked position. The distance between the third and fourth protrusions and the unlocked position, and the distance between the fourth and unlocked positions, constitute the rotation radius, so that the rotation of the disc is not affected by the limiting structure, and the rotation is reliable.

[0010] As an improvement, the distance between the outer walls of the first and second protrusions is less than the length of the second or third slide rail. When the connecting shaft is in the unlocked position and the disc rotates 90 degrees, the outer wall of the first protrusion abuts against one end of the second or third slide rail, and the outer wall of the second protrusion abuts against the other end of the second or third slide rail, thereby locking the disc in a sliding manner. In this technical solution, the distance between the outer walls of the first and second protrusions refers to the distance between the outer wall endpoints of the first protrusion closest to the second protrusion and the outer wall endpoints of the second protrusion closest to the first protrusion. If the first, second, third, and fourth protrusions are arranged in a rectangular pattern, then the distance between the outer walls of the first and second protrusions is equal to the distance between the outer walls of the third and fourth protrusions, and the length of the second slide rail is equal to the length of the third slide rail. This ensures that when the disc rotates 90 degrees or 270 degrees, the first protrusion... One protruding outer wall abuts against one end of the second slide rail, and the other end of the second protruding outer wall abuts against the other end of the second slide rail. That is, the second slide rail is limited by the first and second protrusions, preventing the plate from sliding. Alternatively, the outer wall of the first protrusion abuts against one end of the third slide rail, and the other end of the third protrusion abuts against the other end of the third slide rail. That is, the third slide rail is limited by the first and second protrusions, preventing the plate from sliding. The plate can only rotate on the base, preventing the plate from sliding into the interior of the refrigerator or cabinet and causing a collision, making it safer and more reliable to use.

[0011] As an improvement, each of the first, second, third, and fourth protrusions is equipped with a first ball bearing, and the base uses the first ball bearing to assist the rotation of the disc. In this technical solution, the first, second, third, and fourth protrusions are all configured as ball bearing seats to install the first ball bearing. The first ball bearing contacts the bottom of the disc, which assists the disc's rotation, making the disc rotate more smoothly and easily, and increasing the rotation efficiency.

[0012] As an improvement, the first, second, and third slide rails are all linear slide rails, and all three slide rails are arranged along the width direction of the base; the first slide rail has a groove structure, and the second and third slide rails have protruding structures. In this technical solution, the first slide rail is a linear slide rail, and the connecting shaft slides linearly along the first slide rail under force, allowing the user to directly push and pull the disc, thereby extending or retracting the disc. The linear first slide rail has higher sliding efficiency and requires less effort to use. Furthermore, the first slide rail is set along the width direction of the base, so the center of gravity of the disc remains on the base after it slides out, making the sliding extension and retraction more stable and reliable. The second and third slide rails are also linear slide rails, and they can slide linearly under force, which is more effective in assisting the sliding of the disc. The linear sliding is more efficient and requires less effort to use. The first slide rail has a groove structure, which can accommodate the connecting shaft, avoiding excessive gaps between the disc and the base due to the excessive length of the connecting shaft. The second and third slide rails have raised structures. The second slide rail abuts laterally with the first and third raised structures, and the third slide rail abuts laterally with the second and fourth raised structures. The overall structural design is more reasonable and reliable.

[0013] As an improvement, the base is provided with an annular bracket, on which multiple second ball bearings are installed. The base uses these second ball bearings to assist the rotation of the disc. The annular bracket surrounds the first slide rail. In this technical solution, by setting an annular bracket with multiple second ball bearings between the base and the disc, the disc rotates more smoothly and easily, resulting in higher rotational efficiency. Furthermore, by setting the annular bracket around the first slide rail, the disc remains in contact with the second ball bearings during sliding and extension, ensuring that the disc receives rotational assistance from the second ball bearings during rotation, making it more efficient and reliable.

[0014] As an improvement, the base is provided with several third ball bearings, which are aligned with the first slide rail; multiple suction cups are installed at the bottom of the base. In this technical solution, by setting multiple third ball bearings between the base and the disc body, the disc body rotates more smoothly and easily, with higher rotation efficiency. Furthermore, the alignment of the third ball bearings with the first slide rail provides assistance for both the sliding and rotation of the disc body. On the other hand, considering that the turntable is mainly installed in the internal cavity of a refrigerator or cabinet, and that the internal cavity of the refrigerator or cabinet already has partitions, by installing multiple suction cups at the bottom of the base, the turntable can be connected to the partition through the suction cups when it is installed, resulting in a simple and reliable fixing structure.

[0028] like Figures 1 to 8 As shown, this application discloses a turntable, including a base 1 and a plate 2. The bottom of the plate 2 is provided with a connecting shaft 21 for rotatable connection with the base 1. The base 1 is provided with a first slide rail 11 for sliding the connecting shaft 21. The placement position of the turntable includes, but is not limited to, the inner cavity of a refrigerator and the inner cavity of a cabinet. When a certain number of items are placed in the inner cavity, the items located on the inside are difficult to be taken out directly. However, by placing the turntable in the inner cavity, the items are placed on the plate 2 of the turntable. The plate 2 is rotatably connected to the base 1 through the connecting shaft 21. The plate 2 can rotate 360 ​​degrees on the base 1 through the connecting shaft 21. The items on the inside can be rotated to the outside by rotating the plate 2 for easy access. Considering that some inner cavities are quite deep, even after rotating the plate 2, there is still a long distance to reach the item. This solution provides a first slide rail 11 on the base 1, and the connecting shaft 21 is installed in the first slide rail 11. The plate 2 can slide along the first slide rail 11 to extend or retract under force through the connecting shaft 21. Users can push and pull the plate 2 to meet more usage needs.

[0029] The base 1 is provided with a first protrusion 12 and a second protrusion 13. The bottom of the disc body 2 is provided with a limiting structure, which includes a second slide rail 22 and a third slide rail 23 symmetrically distributed. The first protrusion 12 abuts against the second slide rail 22 and the second protrusion 13 abuts against the third slide rail 23 to lock the disc body 2 in rotation, thereby limiting the left and right sides of the disc body 2 so that the disc body 2 cannot rotate relative to the base 1 in the initial state. The initial state mentioned in this application refers to the disc body 2 being horizontally placed relative to the base 1 and the disc body 1 not rotating. The first protrusion 12 slides along the second slide rail 22 and disengages from the second slide rail 22, and the second protrusion 13 slides along the third slide rail 23 and disengages from the third slide rail 23 to unlock the disc body 2 from rotation.

[0030] When the connecting shaft 21 slides along the first slide rail 11 until the plate body 2 is in the extended state relative to the base 1, the plate body 2 drives the limiting structure to slide synchronously, so that the first protrusion 12 slides along the second slide rail 22 and disengages from the second slide rail 22, and the second protrusion 13 slides along the third slide rail 23 and disengages from the third slide rail 23, thereby allowing the plate body 2 to rotate and unlock. The plate body 2 can rotate 360 ​​degrees on the base 1. Through the cooperation of the limiting structure with the first protrusion 12 and the second protrusion 13, the plate body 2 is locked in the initial state. The plate body 2 can only rotate freely in the extended state, avoiding the plate body 2 from rotating randomly in the refrigerator cavity and cabinet cavity and affecting storage, making it more reliable and providing a better user experience.

[0031] More specifically, such as Figure 7 As shown, the limiting structure includes a first arc-shaped slide rail 24 and a second arc-shaped slide rail 25. The first arc-shaped slide rail 24 is located on one side of the second slide rail 22 and is used to guide the rotation of the first protrusion 12 or the second protrusion 13. The second arc-shaped slide rail 25 is located on one side of the third slide rail 23 and is used to guide the rotation of the second protrusion 13 or the first protrusion 12. When the connecting shaft 21 slides along the first slide rail 11 until the disc body 2 is in an extended state relative to the base 1, the disc body 2 can rotate 360 ​​degrees about the connecting shaft 21 as the center. 2. The first protrusion 12 slides away from the second slide rail 22, and the second protrusion 13 slides away from the third slide rail 23. The first protrusion 12 and the connecting shaft 21, and the second protrusion 13 and the connecting shaft 21 are all within the radius of rotation. When the disc body 2 rotates, the first protrusion 12 can slide along the first arc-shaped slide rail 24, or the first protrusion 12 can slide along the second arc-shaped slide rail 25, or the second protrusion 13 can slide along the first arc-shaped slide rail 24, or the second protrusion 13 can slide along the second arc-shaped slide rail 25, thereby assisting the disc body 2 to rotate, improving the rotation efficiency of the disc body 2, and preventing the disc body 2 from rotating off-center.

[0032] More specifically, such as Figure 3As shown, the first arc-shaped slide rail 24 is joined end-to-end with the second slide rail 22, and the second arc-shaped slide rail 25 is joined end-to-end with the third slide rail 23. The first arc-shaped slide rail 24 is connected to one end of the second slide rail 22, and the other end of the first arc-shaped slide rail 24 is connected to the other end of the second slide rail 22, extending the sliding guide path of the first arc-shaped slide rail 24 to the first protrusion 12 or the second protrusion 13 as much as possible, making the sliding more efficient and reliable. Similarly, the second arc-shaped slide rail 25 is connected to one end of the third slide rail 23, and the other end of the second arc-shaped slide rail 25 is connected to the other end of the third slide rail 23, extending the sliding guide path of the second arc-shaped slide rail 25 to the first protrusion 12 or the second protrusion 13 as much as possible, making the sliding more efficient and reliable.

[0033] More specifically, such as Figures 4 to 8 As shown, the first slide rail 11 is provided with a locking position 111 and an unlocking position 112. By pushing and pulling the disc body 2, the connecting shaft 21 can slide and switch between the locking position 111 and the unlocking position 112 within the first slide rail 11. When the connecting shaft 21 is in the locking position 111, the disc body 2 is in the initial state relative to the base 1. The first protrusion 12 abuts against the second slide rail 22, and the second protrusion 13 abuts against the third slide rail 23 to lock the rotation of the disc body 2. When the connecting shaft 21 is in the unlocking position 112, the disc body 2 is in the extended state relative to the base 1. The first protrusion 12 disengages from the second slide rail 22, and the second protrusion 13 disengages from the third slide rail 23 to unlock the rotation of the disc body 2.

[0034] When the connecting shaft 21 slides along the first slide rail 11 to the locking position 111, as Figure 5 As shown, the disc 2 is in the initial state relative to the base 1. The initial state mentioned in this application refers to the disc 2 being horizontally positioned relative to the base 1 and not rotating. At this time, the first protrusion 12 and the second slide rail 22, and the second protrusion 13 and the third slide rail 23 are all in contact in the horizontal direction, thereby locking the disc 2 in rotation. The disc 2 cannot rotate on the base 1. When the connecting shaft 21 slides along the first slide rail 11 to the unlock position 112, as... Figure 6 As shown, the tray 2 is in an extended state relative to the base 1. The tray 2 drives the limiting structure to slide, so that the first protrusion 12 and the second slide rail 22, and the second protrusion 13 and the third slide rail 23 are all relatively disengaged, thereby allowing the tray 2 to rotate and unlock. The tray 2 can rotate 360 ​​degrees on the base 1, realizing that the tray 2 is rotated and locked in the initial state. The tray 2 can only rotate freely in the extended state, avoiding the tray 2 from rotating randomly in the refrigerator cavity and cabinet cavity and affecting storage, making it more reliable and providing a better user experience.

[0035] More specifically, such as Figures 4 to 8As shown, the base 1 is symmetrically provided with a third protrusion 14 and a fourth protrusion 15. The first protrusion 12, the second protrusion 13, the third protrusion 14, and the fourth protrusion 15 are arranged in a rectangular pattern. By adding the third protrusion 14 and the fourth protrusion 15, the rotation limit of the disc 2 in the initial state is made more reliable, which can prevent the disc 2 from shaking on the base 1 and improve stability. On the other hand, considering that the internal cavity of refrigerators and cabinets is roughly rectangular, with limited height and large depth, in order to adapt to such rectangular internal cavities, the disc 2 and the base 1 in this application are roughly rectangular in structure. Compared with a circular turntable, it can accommodate more items. The first protrusion 12, the second protrusion 13, the third protrusion 14, and the fourth protrusion 15 with ball bearing assembly are arranged in a rectangular pattern, which is more suitable for the rotation of the rectangular disc 2. When the connecting shaft 21 is in the locking position 111, the first protrusion 12 and the third protrusion 14 abut against the second slide rail 22, and the second protrusion 13 and the fourth protrusion 15 abut against the third slide rail. 23 Abutting: Each protrusion abuts against the limiting structure in the horizontal direction, thus limiting the disc body 2 to the base 1 and preventing it from rotating. The first protrusion 12 and the third protrusion 14 can only slide back and forth along the second slide rail 22, and the second protrusion 13 and the fourth protrusion 15 can only slide back and forth along the third slide rail 23. When the connecting shaft 21 is in the unlocked position 112, the second slide rail 22 slides outward relative to the first protrusion 12 and the third protrusion 14, and the third slide rail 23 slides outward relative to the second protrusion 13 and the fourth protrusion 15, thereby allowing the disc body 2 to slide outward relative to the base 1. At this time, the first protrusion 12 disengages from the second slide rail 22, the third protrusion 14 abuts against the second slide rail 22, the second protrusion 13 disengages from the third slide rail 23, and the fourth protrusion 15 abuts against the third slide rail 23, allowing the disc body 2 to rotate 360 ​​degrees on the base 1. The disc body 2 can only rotate freely in the extended state. The structure is ingeniously designed and simple and reliable to use.

[0036] The third protrusion 14 and the fourth protrusion 15 are both flush with the unlocking position 112. The distance between the third protrusion 14 and the unlocking position 112, and the distance between the fourth protrusion 15 and the unlocking position 112, constitute the rotation radius, so that the rotation of the disc body 2 is not affected by the limiting structure and the rotation is reliable.

[0037] More specifically, such as Figure 8As shown, the distance between the outer walls of the first protrusion 12 and the second protrusion 13 is less than the length of the second slide rail 22. The distance between the outer walls of the first protrusion 12 and the second protrusion 13 refers to the distance between the endpoint of the outer wall of the first protrusion 12 closest to the second protrusion 13 and the endpoint of the outer wall of the second protrusion 13 closest to the first protrusion 12. Since the first protrusion 12, the second protrusion 13, the third protrusion 14, and the fourth protrusion 15 are arranged in a rectangular shape, the distance between the outer walls of the first protrusion 12 and the second protrusion 13 is equal to the distance between the outer walls of the third protrusion 14 and the fourth protrusion 15. Furthermore, the length of the second slide rail 22 is equal to the length of the third slide rail 23, thereby ensuring... When the plate 2 rotates 90 degrees or 270 degrees, the outer wall of the first protrusion 12 abuts against one end of the second slide rail 22, and the outer wall of the second protrusion 13 abuts against the other end of the second slide rail 22. That is, the second slide rail 22 is limited by the first protrusion 12 and the second protrusion 13, preventing the plate 2 from sliding. Alternatively, the outer wall of the first protrusion 12 abuts against one end of the third slide rail 23, and the outer wall of the second protrusion 13 abuts against the other end of the third slide rail 23. That is, the third slide rail 23 is limited by the first protrusion 12 and the second protrusion 13, preventing the plate 2 from sliding. The plate 2 can only rotate on the base 1, preventing the plate 2 from sliding into the inner cavity of the refrigerator or cabinet and causing a collision, making it safer and more reliable to use.

[0038] More specifically, the first protrusion 12, the second protrusion 13, the third protrusion 14 and the fourth protrusion 15 are all equipped with first ball bearings 16. The base 1 assists the disk body 2 to rotate through the first ball bearings 16. The first protrusion 12, the second protrusion 13, the third protrusion 14 and the fourth protrusion 15 are all ball bearing seat structures for installing the first ball bearings 16. The first ball bearings 16 contact the bottom of the disk body 2 to assist the disk body 2 to rotate, thereby making the disk body 2 rotate more smoothly and quickly, and with higher rotation efficiency.

[0039] More specifically, such as Figure 2 and Figure 4As shown, the first slide rail 11, the second slide rail 22, and the third slide rail 23 are all linear slide rails, arranged along the width direction of the base 1. The first slide rail 11 is a linear slide rail, and the connecting shaft 21 slides linearly along the first slide rail 11 under force, allowing the user to directly push and pull the disc 2, thus extending or retracting the disc 2. The linear first slide rail 11 has higher sliding efficiency and requires less effort to use. Furthermore, since the first slide rail 11 is arranged along the width direction of the base 1, the center of gravity of the disc 2 after sliding out remains on the base 1, making the sliding extension and retraction more stable and reliable. The second slide rail 22 and the third slide rail 23 are also linear slide rails. The third slide rail 23 can slide linearly through the ball assembly under force, which is more effective in assisting the sliding of the disc body 2. The linear sliding is more efficient and less labor-intensive. The first slide rail 11 has a groove structure, while the second slide rail 22 and the third slide rail 23 have protruding structures. The first slide rail 11 with a groove structure can accommodate the connecting shaft 21, avoiding the connection shaft 21 being too long and causing the gap between the disc body 2 and the chassis to be too large. The second slide rail 22 and the third slide rail 23 with protruding structures are designed such that the second slide rail 22 abuts laterally with the first protrusion 12 and the third protrusion 14, and the third slide rail 23 abuts laterally with the second protrusion 13 and the fourth protrusion 15. The overall structural design is more reasonable and reliable.

[0040] More specifically, such as Figure 4 As shown, one end of the first slide rail 11 is set as the locking position 111, and the other end of the first slide rail 11 is set as the unlocking position 112. With the locking position 111 and the unlocking position 112 respectively set on both ends of the first slide rail 11, the user can push and pull the disc body 2, and the disc body 2 will slide out or retract into place by the connecting shaft 21 abutting against the end of the first slide rail 11, making the operation simpler and less strenuous.

[0041] More specifically, such as Figure 2 and Figure 4 As shown, a ring bracket 4 is provided on the base 1, and multiple second ball bearings 41 are installed on the ring bracket 4. The base 1 assists the rotation of the disc 2 through the second ball bearings 41. The ring bracket 4 is arranged around the first slide rail 11. By setting the ring bracket 4 with the second ball bearings 41 installed between the base 1 and the disc 2, and by installing multiple second ball bearings 41, the disc 2 rotates more smoothly and quickly through the multiple second ball bearings 41, and the rotation efficiency is higher. On the other hand, the ring bracket 4 is arranged around the first slide rail 11 so that the disc 2 remains in contact with the second ball bearings 41 during the sliding and extension process, so that the disc 2 can be assisted by the rotation of the second ball bearings 41 when rotating, making it more efficient and reliable.

[0042] More specifically, such as Figure 2 and Figure 4As shown, the base 1 is provided with several third ball bearings 5. The third ball bearings 5 ​​and the first slide rail 11 are located on the same straight line. By setting multiple third ball bearings 5 ​​between the base 1 and the disc 2, the disc 2 rotates more smoothly and quickly through the multiple third ball bearings 5, and the rotation efficiency is higher. Moreover, the third ball bearings 5 ​​and the first slide rail 11 are located on the same straight line, and the third ball bearings 5 ​​can play an auxiliary role in the sliding and rotation of the disc 2. On the other hand, considering that the turntable is mainly installed in the internal cavity of the refrigerator or cabinet, and the internal cavity of the refrigerator or cabinet is already provided with partitions, by installing multiple suction cups 3 at the bottom of the base 1, the turntable can be connected to the partition through the suction cups 3 when it is installed on the partition. The fixing structure is simple and the stability is reliable.

However, regardless of any changes made to their shape or structure, any technical solution that is the same as or similar to that of this application falls within the protection scope of this application.
