[0017] Preferably, the upper end of the base is a detachable structure.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention is provided with a rotary display mechanism. By turning on the reduction motor, its output shaft drives the limit transmission rod to rotate through the rotating shaft, drives the gear on the driving gear set to rotate, and drives the worm to rotate under the meshing with the transmission gear. The contact surface between the worm and the worm wheel forms a spiral friction transmission surface. The rotation of the worm drives the worm wheel to rotate, and then drives the first rotating column to rotate through the worm wheel, and finally realizes the rotation of the upper display seat, and the furniture placed above the display seat is displayed in a circular manner, thereby overcoming the problem that multiple household products cannot be displayed simultaneously when the venue is limited.

[0020] 2. The present invention is based on the problem that the number of directions of the products to be displayed cannot be adjusted. It is realized by meshing different sector-shaped drive gears with the transmission gear. The drive gear set is composed of sector-shaped drive gears with different filling angles. The filling angle of the tooth ring on the first sector-shaped drive gear is the smallest. When it meshes with the transmission gear, the display seat can be rotated by a fixed angle with the center of the transmission disk as the origin through the worm gear transmission mechanism. Since the filling angle of the tooth ring is the smallest, the rotation angle is also small. When the outer tooth ring of the first sector-shaped drive gear loses meshing with the transmission gear, the transmission gear loses driving force. With the self-locking property of the worm gear, the display seat remains fixed at the stop position to ensure stability. At the same time, the residence time is longer than that of other sector-shaped drive gears. When the number of display directions needs to be adjusted, the servo motor is turned on, and its output shaft drives the threaded rod to rotate. When it is in contact with the adjustment Under the friction of the screw hole in the rod, the first limit slide groove guides the adjustment rod to drive the adjustment rod to move horizontally. During the movement, the position of the drive gear set is adjusted, so that the appropriate fan-shaped drive gear is meshed with the transmission gear. At the same time, in order to meet the rationality of the adjustment process, the output end of the reduction motor and the drive gear set are movably connected. On the one hand, the limit transmission rod on the rotating shaft extends to the second limit slide groove inside the drive gear set to provide space for the movement of the drive gear set. On the other hand, the outer protrusion of the limit transmission rod is engaged with the groove in the second limit slide groove, and the drive gear set can be driven to rotate through the limit transmission rod, thereby providing a prerequisite for the rotation display of the display seat. The display direction quantity switching structure realizes the precise control of the rotation angle of the display seat by utilizing the meshing of the fan-shaped drive gear with different filling angles and the transmission gear. This design allows users to easily adjust the rotation angle and stay time of the display seat according to actual needs, so as to adapt to the needs of different numbers of display directions, greatly improving the flexibility and applicability of the equipment.

[0021] 3. Based on the problem of incomplete display directions, the present invention is provided with a transmission plate. During the rotation of the first rotating column, the central gear will be driven to rotate, and the planetary gears distributed around the outside of the central gear will respectively mesh with the central gear and the annular transmission tooth grooves on the inner wall of the transmission plate. Therefore, during the rotation of the central gear, the planetary gears will revolve around the central gear while maintaining their own rotation. A second rotating column connected to the display seat is fixedly provided at the central axis of the upper end of the planetary gear. Then, during the actual display of the furniture, in conjunction with the display direction quantity switching structure, when the transmission gear loses engagement with the fan-shaped drive gear, the furniture is facing the visitor. When the two resume engagement, the furniture moves to the next display direction, and at the same time, it maintains its own rotation at a set speed, allowing the visitor to observe other positions of the moving furniture. Moreover, when the furniture rotates one circle and returns to the direction again, it can maintain different display positions. Visitors can observe different sides and features of the furniture without moving their positions, thereby improving the visitor's visiting experience. The design is highly flexible and adjustable, and can be adjusted according to different display needs and scenes. By switching the display direction quantity structure, the rotation path and rotation speed of the furniture can be easily changed to meet the display needs of furniture of different types and styles.

[0032] The driving gear set 8 is arranged on one side of the transmission gear 7. The driving gear set 8 consists of a first sector-shaped driving gear 23, a second sector-shaped driving gear 24, a third sector-shaped driving gear 25, a fourth sector-shaped driving gear 26 and a fifth sector-shaped driving gear 27, and one of the sector-shaped driving gears is meshed and connected with the transmission gear 7. An adjustment mechanism 13 is provided at one end of the driving gear set 8 for switching the meshing of different sector-shaped driving gears with the transmission gear 7.

[0033] See also Figure 2 , Figure 3 and Figure 4The adjusting mechanism 13 includes a first limiting slide groove 15, an adjusting rod 14 is installed inside the first limiting slide groove 15, the outer wall of the adjusting rod 14 is slidably limited with the first limiting slide groove 15, and the outer end of the adjusting rod 14 is connected to the driving gear set 8 through a bearing seat 29, a servo motor 16 is arranged at one end of the first limiting slide groove 15 away from the adjusting rod 14, and the servo motor 16 is fixed to the base 1, a threaded rod 17 is installed on the output shaft of the servo motor 16, the threaded rod 17 passes through the first limiting slide groove 15 and extends to the inside of the adjusting rod 14, and the outer thread of the threaded rod 17 is frictionally matched with the inner screw hole of the adjusting rod 14, the threaded rod 17 is driven to rotate by the servo motor 16, and the frictional cooperation between the threaded rod 17 and the inner screw hole of the adjusting rod 14 is utilized to realize the precise control of the position of the adjusting rod 14. This design makes the switching of meshing between different sector-shaped driving gears and the transmission gear 7 very accurate and reliable, ensuring stability and consistency during the display process. The first limit slide groove 15 provides a stable sliding limit for the adjustment rod 14, ensuring stability and no shaking during the adjustment process. At the same time, the adjustment rod 14 is connected to the driving gear set 8 through the bearing seat 29, which further enhances the stability and durability of the structure and prolongs the service life of the equipment.

[0034] See also Figure 4 and Figure 5 , a second limiting slide 28 is provided inside the other end of the driving gear set 8, a limiting transmission rod 10 is installed inside the second limiting slide 28, and the limiting transmission rod 10 and the second limiting slide 28 are slidably limited, and a rotating shaft 11 is fixedly installed on the end of the limiting transmission rod 10 away from the driving gear set 8, and a reduction motor 12 is connected to the other end of the rotating shaft 11, and the housing of the reduction motor 12 is fixed to the base 1, and the output shaft of the reduction motor 12 is fixed to the rotating shaft 11 through a coupling, and the second limiting slide 28 provides a stable sliding track for the limiting transmission rod 10, ensuring the stability and accuracy of the limiting transmission rod 10 during movement, and the rotating shaft 11 is driven to rotate by the reduction motor 12, thereby driving the limiting transmission rod 10 to slide in the second limiting slide 28, thereby realizing flexible adjustment of the position of the driving gear set 8.

[0035] See also Figure 2 , Figure 3 and Figure 4, the tooth ring filling angles of the first sector drive gear 23, the second sector drive gear 24, the third sector drive gear 25, the fourth sector drive gear 26 and the fifth sector drive gear 27 are increased one by one. The smaller the tooth ring filling angle of the sector drive gear on the drive gear set 8, the more display directions there are and the longer the residence time of the corresponding surface. On the contrary, the larger the tooth ring filling angle, the fewer display directions there are and the shorter the residence time of the corresponding surface. By adjusting the tooth ring filling angle of the sector drive gear, the number of display directions and the residence time of each display surface can be flexibly controlled. This design enables the device to adapt to the display needs of furniture of different types and quantities, and provides a variety of display effects. The incremental design of the tooth ring filling angle allows the user to accurately control the rhythm of the display as needed. A smaller tooth ring filling angle means more display directions and longer residence time, which is suitable for furniture that needs to be displayed in detail; while a larger tooth ring filling angle reduces the number of display directions and shortens the residence time, which is suitable for quick browsing or displaying a large number of furniture.

[0036] See also Figure 4 and Figure 6 A central gear 21 is installed at the middle position inside the transmission disk 2, and the central gear 21 is rotationally connected to the transmission disk 2, and the upper end of the first rotating column 18 is fixed to the bottom of the central gear 21, and the outside of the central gear 21 is provided with planetary gears 22 of the same number as the display seat 3, and the planetary gears 22 are distributed in an annular shape and equidistantly, and an annular transmission tooth groove 20 is provided on the inner wall of the transmission disk 2, and the planetary gears 22 are respectively meshed and connected with the central gear 21 and the annular transmission tooth groove 20, and an annular guide groove 4 is provided on the upper end of the transmission disk 2, and a second rotating column 19 is fixedly arranged at the middle position of the upper end surface of the planetary gear 22, and the outer wall of the second rotating column 19 is slidably matched with the annular guide groove 4, and the upper end of the second rotating column 19 is fixed to the display seat 3. The central gear 21 serves as the core of the transmission system, and its fixed connection with the first rotating column 18 ensures the stability of the overall rotation of the transmission disk 2. The meshing of the planetary gear 22 with the central gear 21 and the annular transmission tooth groove 20 forms a stable transmission chain, making the rotation of the transmission plate 2 more stable. Through the coordinated work of the planetary gear 22 with the central gear 21 and the annular transmission tooth groove 20, the display stand 3 is rotated stably, synchronously and equidistantly. This display method can attract the audience's attention, improve the display effect, and enable furniture products to be better displayed and promoted.

[0037] See also Figure 1 and Figure 4The base 1 is provided with an oil groove 30 at a position below the driving gear set 8, and the lower end portion of the driving gear set 8 is located inside the oil groove 30. A lubricating oil adding pipe 31 is provided outside the base 1, and the lubricating oil adding pipe 31 is connected to the oil groove 30. When the lubricating oil in the oil groove 30 is insufficient, it is only necessary to inject a proper amount of lubricating oil into the oil groove 30 through the lubricating oil adding pipe 31, without disassembling the device or performing complicated maintenance operations. This design reduces the difficulty and cost of maintenance, improves the reliability and availability of the device, and by maintaining a good lubrication state of the driving gear set 8, it can ensure that the transmission disk 2 and the display seat 3 thereon remain stable and stable during the rotation process.

[0038] Working principle: When in use, when the number of display directions is adjusted first, the servo motor 16 is turned on, and its output shaft drives the threaded rod 17 to rotate. Under the friction with the inner screw hole of the adjustment rod 14, the adjustment rod 14 is driven to move horizontally in cooperation with the guiding effect of the first limit slide groove 15 on the adjustment rod 14. During the movement, the position of the drive gear set 8 is adjusted, so that the appropriate sector drive gear is engaged with the transmission gear 7. By turning on the reduction motor 12, its output shaft drives the limit transmission rod 10 to rotate through the rotating shaft 11, and then drives the gears on the drive gear set 8 to rotate. The drive gear set 8 is composed of sector drive gears with different filling angles, among which the toothed ring filling angle on the first sector drive gear 23 is the smallest. When it is engaged with the transmission gear 7, the display seat 3 can be rotated by a fixed angle with the center of the transmission disk 2 as the origin through the worm gear 5 and the worm 6 transmission mechanism. Since the toothed ring filling angle is the smallest, the rotation angle is also small. The worm 6 is driven to rotate under the meshing with the transmission gear 7. The contact surface between the worm 6 and the worm wheel 5 forms a spiral friction transmission surface. The rotation of the worm 6 drives the worm wheel 5 to rotate, and then the worm wheel 5 drives the first rotating column 18 to rotate. The planetary gears 22 distributed around the outside of the central gear 21 are respectively meshed with the central gear 21 and the annular transmission tooth grooves 20 on the inner wall of the transmission plate 2. Therefore, during the rotation of the central gear 21, the planetary gears 22 will revolve around the central gear 21 while maintaining their own rotation. The second rotating column 19 connected to the display seat 3 is fixed at the central axis of the upper end of the planetary gear 22. Then, during the actual display of the furniture, in conjunction with the display direction quantity switching structure, when the transmission gear 7 loses meshing with the fan-shaped drive gear, the transmission gear 7 loses driving force. In conjunction with the self-locking property of the worm wheel 5 and the worm 6, the display seat 3 remains fixed at the stop position to ensure stability. At the same time, the stay time is also longer than that of other fan-shaped drive gears. The furniture is facing the visitors. When the two are re-engaged, the furniture moves to the next display direction, while keeping rotating at the set speed, allowing visitors to observe other positions of the moving furniture. And when the furniture rotates a circle and returns to the direction again, it can maintain different display positions.

[0039] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
