Description

Technical Field

[0001] This utility model relates to the field of display stand technology, and in particular to a rotating model display stand. Background Technology

[0002] The display stand is used to display models for people to view. The display stand consists of a base, a support frame, a cylinder, a rotating shaft, and a placement platform. When using the display stand, staff place the model on the placement platform, and visitors can manually rotate the placement platform, which is then rotated by the rotating shaft inside the cylinder on the support frame on the base, allowing for a better view of the model.

[0003] The inventors discovered in their daily work that when displaying a model, the pivot is usually welded to the platform, which means that a larger platform is needed when displaying a larger model. However, since the platform cannot be replaced, it is necessary to purchase a larger display platform, which may increase the cost of purchasing the display platform. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in actual use, since the rotating shaft is usually welded and fixed to the placement platform, a larger placement platform is required when displaying a larger model. However, since the placement platform cannot be replaced, it is necessary to purchase an additional display platform with a larger placement platform, which may increase the cost of purchasing the display platform. Therefore, a rotating model display platform is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rotating model display stand, comprising a base, a support frame fixedly connected to the upper end of the base, a cylinder fixedly connected to one side of the support frame, a rotating shaft rotatably connected by bearings on the inner wall of the cylinder, a placement platform provided at the upper end of the rotating shaft, a replacement assembly provided between the placement platform and the rotating shaft, the replacement assembly comprising a pin slidably inserted into the arc surface of the rotating shaft, a fixing ring fixedly connected to the lower end of the placement platform, and the pin inserted into the fixing ring.

[0006] The effect achieved by the above components is as follows: by setting up the replacement component, when replacing a larger placement platform, the pulling mechanism is used to fully retract the pin to the rotating shaft, thereby compressing the reset mechanism. Then, the placement platform is dragged for disassembly. Then, the larger placement platform is dragged so that the retaining ring is inserted into the rotating shaft. The pulling mechanism is released, which resets the reset mechanism and allows the pin to be inserted into the retaining ring, thereby achieving the effect of replacing a larger placement platform as much as possible.

[0007] Preferably, a first spring is fixedly connected to the right end of the pin, and the other end of the first spring is fixed to the rotating shaft.

[0008] The effect achieved by the above components is that by setting the first spring and pulling the mechanism, the pin is fully retracted to the pivot, thereby compressing the first spring.

[0009] Preferably, a pull rope is fixedly connected to the right end of the pin, and the pull rope passes through the rotating shaft.

[0010] The effect achieved by the above components is that pulling the pull rope causes the pin to retract completely into the pivot.

[0011] Preferably, one end of the pin has a sliding surface, and the inner wall of the fixing ring has an auxiliary surface.

[0012] The effect achieved by the above components is as follows: by setting a sliding surface, the auxiliary pin is inserted into the fixed ring; by setting an auxiliary surface, the auxiliary rotating shaft is inserted into the fixed ring.

[0013] Preferably, a mounting bracket is fixedly connected to the upper end of the base, a motor is installed at the lower end of the mounting bracket, the motor controls the rotation of the first sprocket, a second sprocket is fixedly connected to the arc surface of the rotating shaft, and a chain is provided between the first sprocket and the second sprocket.

[0014] The effect achieved by the above components is as follows: the motor is started by the controller, the motor is connected to the first sprocket through the reducer and coupling, so that the first sprocket rotates, the second sprocket rotates with the help of the chain, the shaft rotates, and the placement platform rotates, so that no manual rotation is required.

[0015] Preferably, an annular groove is provided between the base and the rotating shaft, and the inner wall of the annular groove is provided with a plurality of identical ball bearings.

[0016] The effect achieved by the above components is to assist in supporting the rotating shaft by setting annular grooves and ball bearings.

[0017] Preferably, the lower end of the base is provided with a fixing component, the fixing component including a suction cup disposed at the lower end of the base.

[0018] The effect achieved by the above components is that by setting up suction cups, the suction cups adhere to the smooth ground, thus limiting the position of the base.

[0019] Preferably, the suction cup is slidably inserted into the base, and a second spring is fixedly connected between the suction cup and the base.

[0020] The effect achieved by the above components is as follows: the suction cup adheres to the smooth ground, the second spring is in a compressed state, and its reverse force pushes the suction cup, causing the suction cup to be squeezed.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] In this invention, by setting up a replacement component, when replacing a larger placement platform, a pulling mechanism is used to fully retract the pin to the rotating shaft, compressing the reset mechanism. Then, the placement platform is dragged for disassembly. The larger placement platform is then dragged so that the fixing ring is inserted into the rotating shaft. The pulling mechanism is then released, causing the reset mechanism to reset and the pin to insert into the fixing ring. This achieves the goal of replacing the placement platform with a larger one. This solves the problem that since the rotating shaft is usually welded to the placement platform, a larger placement platform is needed when displaying larger models, but since the placement platform cannot be replaced, it is necessary to purchase an additional display stand with a larger placement platform, which may increase the cost of purchasing the display stand.

Detailed Implementation

[0028] Reference Figure 1 As shown, this utility model provides a technical solution: a rotating model display stand includes a base 1, a support frame 5 is fixedly connected to the upper end of the base 1, a cylinder 6 is fixedly connected to one side of the support frame 5, a rotating shaft 7 is provided on the inner wall of the cylinder 6 and is rotatably connected by bearings, a placement platform 4 is provided on the upper end of the rotating shaft 7, and a replacement component 2 is provided between the placement platform 4 and the rotating shaft 7.

[0029] Reference Figure 2 and Figure 3As shown in this embodiment: the replacement component 2 includes a pin 21 that slides onto the arc surface of the rotating shaft 7. A fixing ring 22 is fixedly connected to the lower end of the placement platform 4. The pin 21 is inserted into the fixing ring 22. By setting the replacement component 2, when replacing a larger placement platform 4, the pulling mechanism causes the pin 21 to fully retract to the rotating shaft 7, compressing the reset mechanism. Then, the placement platform 4 is dragged for disassembly. The larger placement platform 4 is then dragged, causing the fixing ring 22 to insert into the rotating shaft 7. Releasing the pulling mechanism resets the reset mechanism, allowing the pin 21 to insert into the fixing ring 22, thereby maximizing the ability to replace a larger placement platform 4. A first spring 25 is fixedly connected to the right end of pin 21. The other end of the first spring 25 is fixed to the rotating shaft 7. By setting the first spring 25, the pulling mechanism causes pin 21 to be fully retracted to the rotating shaft 7, thus compressing the first spring 25. A pull rope 26 is fixedly connected to the right end of pin 21. The pull rope 26 passes through the rotating shaft 7. Pulling the pull rope 26 causes pin 21 to be fully retracted to the rotating shaft 7. A sliding surface 24 is provided at one end of pin 21, and an auxiliary surface 23 is provided on the inner wall of the fixing ring 22. By setting the sliding surface 24, the auxiliary pin 21 is inserted into the fixing ring 22. By setting the auxiliary surface 23, the auxiliary rotating shaft 7 is inserted into the fixing ring 22.

[0030] Reference Figure 2 and Figure 4 As shown, in this embodiment: a mounting bracket 9 is fixedly connected to the upper end of the base 1, and a motor 10 is installed at the lower end of the mounting bracket 9. The motor 10 controls the rotation of the first sprocket 11. A second sprocket 8 is fixedly connected to the arc surface of the rotating shaft 7. A chain 12 is provided between the first sprocket 11 and the second sprocket 8. The motor 10 is started by the controller. The motor 10 is connected to the first sprocket 11 through a reducer and a coupling, causing the first sprocket 11 to rotate. With the help of the chain 12, the second sprocket 8 rotates, causing the rotating shaft 7 to rotate, and the placement platform 4 to rotate. Thus, manual rotation is not required. An opening is provided between the base 1 and the rotating shaft 7. There is an annular groove 13, and the inner wall of the annular groove 13 is provided with multiple identical ball bearings. By setting the annular groove 13 and the ball bearings, the rotating shaft 7 is supported. The lower end of the base 1 is provided with a fixing component 3, which includes a suction cup 31 set at the lower end of the base 1. By setting the suction cup 31, the suction cup 31 is attached to the smooth ground and limits the base 1. The suction cup 31 is slidably inserted into the base 1. A second spring 32 is fixedly connected between the suction cup 31 and the base 1. When the suction cup 31 is attached to the smooth ground, the second spring 32 is in a compressed state, and its reverse force pushes the suction cup 31, thus squeezing the suction cup 31.

[0031] Working principle:

[0032] When using the display stand, staff place the model on the stand 4. Visitors can manually rotate the stand 4, allowing it to rotate via the pivot 7 inside the cylinder 6 on the support frame 5 of the base 1, thus providing a better view of the model. To replace the stand 4 with a larger one, pulling the cord 26 retracts the pin 21 fully into the pivot 7, compressing the first spring 25. The stand 4 is then dragged for disassembly. Dragging the larger stand 4 allows the retaining ring 22 to engage with the pivot 7. Releasing the cord 26 resets the first spring 25, allowing the pin 21 to re-engage with the retaining ring 22, thus maximizing the ability to replace the stand 4 with a larger one. A sliding surface 24 is also included to assist in this process. The pin 21 is inserted into the fixed ring 22. By setting the auxiliary surface 23, the auxiliary rotating shaft 7 is inserted into the fixed ring 22. The controller starts the motor 10. The motor 10 is connected to the first sprocket 11 through the reducer and coupling, so that the first sprocket 11 rotates. With the help of the chain 12, the second sprocket 8 rotates, so that the rotating shaft 7 rotates, so that the placement platform 4 rotates, so that no manual rotation is required. By setting the annular groove 13 and the ball bearing, the rotating shaft 7 is supported. By setting the suction cup 31, the suction cup 31 is attached to the smooth ground, which limits the base 1. When the suction cup 31 is attached to the smooth ground, the second spring 32 is in a compressed state. Its reverse force pushes the suction cup 31, so that the suction cup 31 is squeezed.
