Example 1

Please refer to FIG. 1 and FIG. 2 , the present embodiment provides an exhibition model rotating exhibition stand, which is used to display the exhibiting goods in the exhibition. Like the conventional exhibition stand, it is provided with a base 6 that supports together. The difference is that it also includes:

The first bearing shaft 1, the first bearing shaft 1 is cylindrical and made of a material with strong load-bearing capacity, such as steel, aluminum or other alloys, and first annular sleeves 7 are sleeved at both ends of the first bearing shaft 1 , the first annular sleeve 7 is evenly distributed with a number of first connecting rods 8 along the circumferential direction, and the first annular sleeve 7 is evenly provided with a number of limiting grooves parallel to the length direction of the first annular sleeve 7. The first bearing shaft 1 and the second bearing shaft 2 are provided with limit protrusions that are adapted to the limit grooves. During assembly, the limit grooves of the first annular sleeve 7 are aligned with the limit protrusions. Insert, the first annular sleeve 7 can be sleeved on the outside of the first bearing shaft 1. This method is more convenient to process and can have a positioning effect on the first annular sleeve 7. Of course, the first annular sleeve 7 and the A bearing shaft 1 can also be connected by a key, screw connection, etc., as long as the first annular sleeve 7 can be rotated with the first bearing shaft 1 .

The second bearing shaft 2 is located below the first bearing shaft 1 and is arranged orthogonally to the first bearing shaft 1 . The two ends of the second bearing shaft 2 are sleeved with second annular sleeves. The annular sleeve is evenly distributed with a number of second connecting rods along the circumferential direction. The connection method between the second annular sleeve and the second bearing shaft 2 is the connection method between the first annular sleeve 7 and the first bearing shaft 1 The same is not repeated here, but in order to prevent the second annular sleeve from sliding in the length direction of the second bearing shaft 2, limit sleeves can be provided at both ends of the second annular sleeve. The screw connection with the second bearing shaft 2 can also be performed by means of screws. Of course, the same is true for the first annular sleeve 7 and the first bearing shaft 1 .

The first bearing shaft 1 and the second bearing shaft 2 are both supported by a support column 3, the support column 3 is located in the middle of the base 6, and the first bearing shaft 1 and the second bearing shaft 2 pass through the support column 3 and can rotate freely , which can be connected with the support column 3 through a bearing.

The annular turntable 4 is fixedly connected to the first connecting rod 8 or the second connecting rod. Taking the first connecting rod 8 as an example, one end of the first connecting rod 8 is fixedly connected to the first annular sleeve 7, and the other end is fixedly connected to the first annular sleeve 7. The annular turntable 4 is fixedly connected, and the first connecting rod 8 is inclined and arranged, and the first connecting rod 8 forms an umbrella shape as a whole. The annular turntable 4 is evenly distributed with a number of hangers 9 for hanging exhibits, and the hangers 9 and the annular turntable 4 rotate. Connected so that when the ring turntable 4 rotates, the hanger 9 and the exhibits are always kept upright.

The circular turntable 5 is located inside the ring-shaped turntable 4, and is arranged coaxially with the ring-shaped turntable 4. The circular turntable 5 is fixedly connected with the end of the first bearing shaft 1 or the second bearing shaft 2. The circular turntable 5. A number of hangers 9 are evenly distributed along the edges. In order to improve the sense of hierarchy of the exhibits during exhibition, the ring turntable 4 can be behind and the circular turntable 5 is in front, and important exhibits are placed on the hangers 9 on the circular turntable 5. , which is closer to the exhibitors, easier to attract the attention of the exhibitors, and plays an emphasizing role.

The driving device drives the annular turntable 4 and the circular turntable 5 to rotate. In this embodiment, the driving device includes a transmission gear 13 respectively arranged on the first bearing shaft 1 and the second bearing shaft 2, and the transmission gear 13 is meshed with a driving gear , the drive gear is connected with a motor, and the two motors are used to drive the first bearing shaft 1 and the second bearing shaft 2 to rotate respectively. At this time, the rotation speed of the two motors can be different, so that the exhibits rotate at different speeds, and the exhibition It is easier for visitors to get a sense of freshness when viewing exhibits with different sides. And in order to allow the exhibitors to have enough time to see each exhibit clearly, an intermittent transmission mechanism can be set between the motor and the driving gear, for example, the driving gear is set as an incomplete gear, so that only the toothed part and the transmission gear are connected. 13 will drive the transmission gear 13 to rotate when it is in contact, or use the cam structure for intermittent transmission, or set the driving gear to the following structure: including the upper arc-shaped protrusion and the lower arc-shaped protrusion arranged coaxially, and the gap between the two Aligned, one end of the upper circular arc-shaped protrusion is connected smoothly with the other end of the lower circular arc-shaped protrusion, and the distance between the upper circular arc-shaped protrusion and the lower circular arc-shaped protrusion is the same as the distance between the transmission teeth of the transmission gear 13. The width is the same. When the motor drives the drive gear to rotate, if the drive gear of the drive gear 13 is stuck between the upper arc-shaped protrusion and the lower arc-shaped protrusion, the drive gear 13 will not rotate with the drive gear, but When the smooth connection between the upper arc-shaped protrusion and the lower arc-shaped protrusion contacts the transmission teeth of the transmission gear 13, the transmission gear 13 is driven to rotate, so that the annular turntable 4 and the circular turntable 5 rotate synchronously. Realize the intermittent rotation of the exhibits, so that visitors can have enough time to observe the exhibits.

Among them, the hanger 9 can use the existing model display cabin, with its own lights and protective baffles, but the cost is relatively high. For this, the following simplified settings can be performed: the hanger 9 includes a suspension part, a bearing platform and a connection suspension The connecting part of the connecting part is a number of reinforcing ribs to reduce the weight of the hanger 9; The overall shape of the connecting portion is trapezoidal or triangular, so that the hanger 9 is easier to keep upright.

At the same time, in order to protect the entire device, a transparent baffle, such as an acrylic plate or a plastic plate, can be provided on the base 6 and arranged around the outer side of the annular turntable 4 .

Example 2
