The following embodiments are used to illustrate the utility model.

[0034] like Figure 1 , Figure 7 , Figure 8 , Figure 5 As shown, an adjustable model device includes: a shell 10, in which a base 13 with adjustable height is provided; a supporting plate 15, which is arranged above the base 13; a display seat 16, which is movably arranged on the supporting plate 15, and a model body 41 is fixedly arranged on the display seat 16; an expansion component 30, which is arranged between the base 13 and the supporting plate 15; the expansion component 30 includes a servo motor 31, a threaded rod 32 driven to rotate by the servo motor 31, and an expansion plate 34 driven to move by the threaded rod 32, and each expansion plate 34 is provided with a supporting part 36 for elastically supporting the display seat 16.

[0035] The display seat 16 is installed on the supporting plate 15, and the height of the base 13 can be raised and adjusted in the cavity of the shell 10, which makes it convenient to observe the model body 41 on the display seat 16; in addition, the expansion component 30 is arranged between the base 13 and the supporting plate 15. When a larger display seat 16 needs to be installed, the expansion plate 34 is driven by the servo motor 31 and the threaded rod 32. After the expansion plate 34 is expanded and extended, it can provide auxiliary support for the larger display seat 16, which is conducive to ensuring the stability of the display seat 16, and can also improve the stability of the model body 41.

[0036] like Figure 1As shown, the housing 10 is a hollow cylinder, and an electric cylinder 11 is fixedly installed at the bottom of the inner cavity of the housing 10, and the top of the piston rod of the electric cylinder 11 is fixedly connected to the bottom of the base 13. A control panel 12 for controlling the servo motor 31 and the electric cylinder 11 is fixedly installed on the upper side of the outer wall of the housing 10, and the control panel 12 is connected to the servo motor 31 and the electric cylinder 11 by electrical signals.

[0037] The setting of the control panel 12 can conveniently control the operation of the electric cylinder 11 and the servo motor 31. The servo motor 31 is a forward and reverse rotating motor. The electric cylinder 11 and the servo motor 31 are also evenly connected with the power supply electrical signal. When the electric cylinder 11 is controlled to work by the control panel 12, the piston rod of the electric cylinder 11 can drive the base 13 to move. When the model body 41 on the display seat 16 needs to be displayed, the display seat 16 and the model body 41 can be driven by the base 13 to move upward. When it is necessary to store, the base 13 drives the carrier plate 15 to move downward, and the carrier plate 15 is stored in the cavity of the shell 10. When the carrier plate 15 is stored in the cavity of the shell 10, the display seat 16 can be taken away from the carrier plate 15 for separate storage, and the display seat 16 can also enter the cavity of the shell 10 with the carrier plate 15 for storage.

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the base 13 and the bearing plate 15 are both disc-shaped, and multiple groups of support rods 14 distributed in a circular array are fixedly arranged between the base 13 and the bearing plate 15; the servo motor 31 is fixedly installed at the bottom center of the bearing plate 15 through a bracket, and the output end of the servo motor 31 is fixedly connected to the first bevel gear 21, and the number of threaded rods 32 is multiple groups, and the multiple groups of threaded rods 32 are distributed in a circular array on the outer upper side of the first bevel gear 21, and the ends of the threaded rods 32 close to the first bevel gear 21 are fixedly arranged with second bevel gears 33, and the second bevel gears 33 are meshed with the first bevel gear 21. The cross section of the expansion plate 34 is rectangular, and an internal threaded hole is opened in the wall surface of one end of the expansion plate 34, and the expansion plate 34 is threadedly connected to the threaded rod 32 through the internal threaded hole, and a limiting sleeve 35 for guiding and limiting the expansion plate 34 is slidably sleeved on the outer wall of the expansion plate 34, and the limiting sleeve 35 is fixedly connected to the bottom wall surface of the bearing plate 15. It is worth noting that the diameter of the supporting plate 15 is smaller than the inner diameter of the housing 10 .

[0039] During use, when the servo motor 31 is controlled to rotate through the control panel 12, the servo motor 31 can drive the first bevel gear 21 to rotate, and multiple groups of second bevel gears 33 are all meshed with the first bevel gear 21. Therefore, when the first bevel gear 21 rotates, the threaded rod 32 can be driven to rotate by the second bevel gear 33. The threaded rod 32 is threadedly connected to its respective expansion plate 34. Therefore, when the threaded rod 32 rotates, the expansion plate 34 can be driven to move. The expansion plate 34 is limited by the limiting sleeve 35. Therefore, when the threaded rod 32 rotates, the expansion plate 34 can be moved toward one side of the first bevel gear 21 or toward the side close to the first bevel gear 21.

[0040] like Figure 5 , Figure 6 As shown, the support part 36 is movably arranged at the other end of each expansion plate 34, the cross section of the support part 36 is rectangular, the other end of the expansion plate 34 is provided with a rectangular through slot, the support part 36 movably passes through the rectangular through slot, the support part 36 is provided with an avoidance groove 37 on the side wall surface close to the first bevel gear 21, the bottom of the support part 36 is fixedly installed with a bottom plate 38, and an elastic component is also arranged between the bottom plate 38 and the bottom wall surface of the expansion plate 34. The elastic component includes a telescopic rod 39 fixedly installed between the bottom plate 38 and the bottom wall surface of the corresponding expansion plate 34, and a tension spring 40 is inserted into the outer wall of the telescopic rod 39.

[0041] Furthermore, when the expansion plate 34 drives the respective support parts 36 to move away from the side corresponding to the first bevel gear 21, after the top of the support part 36 is completely separated from the bottom of the supporting plate 15, under the elastic tension of the tension spring 40, the tension spring 40 pulls the respective bottom plates 38 and drives the support parts 36 to move upward. After the support parts 36 move upward, the top wall surface of the support parts 36 is in a horizontally aligned state with the top wall surface of the supporting plate 15. Multiple groups of support parts 36 can provide auxiliary support to the bottom edge of the display stand 16 with a larger diameter, thereby ensuring the stability of the display stand 16 placed on the supporting plate 15, thereby ensuring the stability of the display of the model body 41.

[0042] When the threaded rod 32 drives the expansion plate 34 to be recovered, the expansion plate 34 drives the support part 36 to move toward the side close to the first bevel gear 21. The avoidance groove 37 first contacts the side wall of the carrier plate 15, and the support part 36 can be guided and pressed along the inclined surface of the avoidance groove 37, and finally the support part 36 is pressed under the bottom wall of the carrier plate 15.

[0043] like Figure 3 , Figure 2As shown, a plurality of groups of first slide grooves 17 distributed in concentric circles are provided on the top wall surface of the carrying plate 15, the gap size of each first slide groove 17 is the same, a slider 18 is slidably installed in each first slide groove 17, the cross-section of the slider 18 is rectangular, and a limiting rod 19 is fixedly installed on the top of the slider 18. A plurality of groups of second slide grooves 20 are also provided on the bottom of the display seat 16, and the second slide grooves 20 correspond to the positions of the first slide grooves 17 up and down, and the top end of the limiting rod 19 extends into the corresponding second slide groove 20.

[0044] When in use, when the display seat 16 is placed on the supporting plate 15, the limiting rod 19 extends into the corresponding second slide groove 20, so that multiple sets of limiting rods 19 can guide and limit the display seat 16. The size of the limiting rod 19 is smaller than the inner diameter of the second slide groove 20. Through the coordinated use of multiple sets of limiting rods 19, the display seat 16 can be prevented from sliding or slipping on the supporting plate 15. When the display seat 16 is used to display the model body 41, the display seat 16 can also be rotated, and the display seat 16 can rotate and display the model body 41.

[0045] It is worth mentioning that when a larger model body 41 needs to be displayed, the size of the display seat 16 will be increased accordingly, and the second slide groove 20 opened on the bottom of the display seats 16 of different sizes are also in the same position as the first slide groove 17 opened on the supporting plate 15, so that the use of model bodies 41 and display seats 16 of different sizes in this solution can be met.
