As shown in fig. 2, chromium plating layers (not shown) are disposed on the surfaces of the drive bevel gear 42 and the driven bevel gear 43, and the chromium plating layers have high hardness and are plated on the surfaces of the drive bevel gear 42 and the driven bevel gear 43, so that the wear resistance of the surfaces of the drive bevel gear 42 and the driven bevel gear 43 is enhanced, the mutual wear between the two is reduced, and the service lives of the two are prolonged.
As shown in fig. 2, a lifting assembly 5 and an adjusting assembly 6 are installed in the transparent plastic barrel 1, and the lifting assembly 5 includes a driving gear 51 and a rack 52. The axis of the driving gear 51 coincides with the axis of the output shaft of the motor 41, and is sleeved on and fixed with the output shaft of the motor 41. The rack 52 is vertically disposed in the transparent plastic barrel 1, and is engaged with the driving gear 51. The adjusting component 6 comprises a vertical plate 61 and an air cylinder 62, wherein the vertical plate 61 is a vertically arranged rectangular plate-shaped structure, the bottom surface of the vertical plate 61 is fixed with the inner bottom wall of the transparent plastic bucket 1, and the vertical plate 61 is arranged in parallel with the rack 52. The cylinder 62 is fixed with the side wall of the vertical plate 61 far away from the rack 52, the piston rod of the cylinder 62 penetrates through the vertical plate 61 and is in sliding fit with the vertical plate, and the end part of the piston rod of the cylinder 62 is fixed with the side wall of the rack 52 far away from the driving gear 51. By arranging the adjusting component 6, when the worker needs to adjust the height of the display disc 3 so that the viewer can observe the bottom of the model in the display disc 3, the worker only needs to adjust the extension of the piston rod of the air cylinder 62, so that the piston rod of the cylinder 62 pushes the rack 52 to move toward the side close to the pinion gear 51 until the rack 52 engages with the pinion gear 51, and then, the worker needs to start the motor 41, the motor 41 drives the driving gear 51 fixed with the output shaft to rotate after working, since the rack 52 is fixed to the end of the piston rod of the cylinder 62, so that the pinion gear 51 moves upward, in the process, the motor 41 and the U-shaped plate 2 fixed to the motor 41 are moved upward in the vertical direction, the slide bar 22 is slid upward along the slide groove 12, thereby being convenient for the viewer to observe the bottom of the model in the display disc 3 and being beneficial to the viewer to carry out all-round observation on the model.
As shown in fig. 2, the rack 52 is provided with the limiting rod 7, the limiting rod 7 is a round rod-shaped structure with a horizontal axis, one end of the limiting rod 7 is fixed to the side wall of the rack 52 far away from one side of the driving gear 51, the other end of the limiting rod 7 penetrates through the vertical plate 61 and is matched with the vertical plate in a sliding manner, and by arranging the limiting rod 7, a good limiting effect is achieved on the movement of the rack 52 to one side of the driving gear 51, so that the probability of shaking occurring in the process that the rack 52 moves to one side of the driving gear 51 is reduced, and the stability of the rack 52 in the movement process is improved.
As shown in fig. 2, the one end of the limiting rod 7 far away from the rack 52 is fixed with a rubber plate 71, the rubber plate 71 is in a circular plate shape, the axis of the rubber plate coincides with the axis of the limiting rod 7, the rubber plate 71 is made of rubber materials and has good elastic performance, through the arrangement of the rubber plate 71, when the limiting rod 7 drives the rack 52 to move towards one side far away from the driving gear 51, the rubber plate 71 plays a good buffering protection role, thereby avoiding the rigid contact between the limiting rod 7 and the inner side wall of the transparent plastic barrel 1, and playing a good protection role for the transparent plastic barrel 1.
The implementation principle of the embodiment is as follows: when different parts of the model on the display disc 3 need to be observed, an observer only needs to drive the rotating rod 21 to rotate through the driving assembly 4, so that the display disc 3 on the rotating rod 21 rotates, the observer can conveniently observe different parts of the model when standing on site, and the experience of the observer in the process of observing the model is improved.
In this scheme, when the different positions of model on the show dish 3 need be observed, the observer only need open motor 41, motor 41 drives the drive bevel gear 42 rotation rather than the output shaft is fixed after the work, in this process, drive bevel gear 42 drives rather than the driven bevel gear 43 rotation of meshing, so that take place to rotate with the dwang 21 that driven bevel gear 43 is fixed, thereby make the show dish 3 of dwang 21 upper end rotate, be favorable to the observer to observe the different positions of model on the show dish 3, so that the observer observes the model comprehensively. When the bottom of the model on the display disc 3 needs to be observed, a worker only needs to adjust the extension of the piston rod of the air cylinder 62, so that the piston rod of the air cylinder 62 pushes the rack 52 to move towards one side close to the driving gear 51 until the rack 52 is meshed with the driving gear 51, and then the worker needs to start the motor 41, the motor 41 drives the driving gear 51 fixed with an output shaft of the motor to rotate after working, and the rack 52 is fixed with the end part of the piston rod of the air cylinder 62, so that the driving gear 51 is easy to move upwards in the vertical direction along the rack 52, and in the process, the motor 41 and the U-shaped plate 2 fixed with the motor 41 both move upwards in the vertical direction, so that the worker can conveniently adjust the heights of the rotating rod 21 and the display disc 3, and the viewer can observe the bottom of the model on the.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
