Description

Technical Field

[0001] The utility model relates to the technical field of photographic equipment, in particular to a load-bearing turntable. Background Art

[0002] Photography can be broadly categorized into three main categories based on its subject matter: portraiture, object photography (also known as still life photography), and landscape photography. Object photography, also known as still life photography, focuses on showcasing an object's form, texture, color, and detail. This type of photography is often used for product presentations, advertising campaigns, and documenting artwork. Still life photography requires sophisticated lighting techniques and precise composition to highlight the object's unique characteristics and beauty. During the shoot, the photographer may employ various angles, backgrounds, props, and lighting to enhance the image's visual impact and appeal.

[0003] Currently, when photographing an object, the object is usually placed on a display stand, and the photographer walks around the display stand to shoot from multiple angles, which is relatively time-consuming and labor-intensive. Although electric rotating display stands are currently provided to automatically rotate the object for easier photography, the rotating stands are generally supported by a separate rotating shaft, which results in poor stability during rotation and is prone to shaking. Moreover, after stopping, the rotating stand will continue to rotate due to inertia and cannot be quickly stopped.

[0004] Therefore, it is necessary to design a load-bearing turntable to solve the problem. Utility Model Content

[0005] The utility model provides a load-bearing turntable, which solves the above-mentioned technical problems.

[0006] In order to solve the above technical problems, the present invention provides a load-bearing turntable, comprising a display stand, wherein universal wheels are fixed at the four corners of the bottom of the display stand, a cavity is opened in the middle of the display stand, and a rotating structure is fixedly installed in the cavity;

[0007] The rotating structure includes a bearing seat fixed in the middle of the display stand, a rotating shaft seat is installed on the top of the bearing seat, a circular iron plate is fixed on the top of the rotating shaft seat, and a transmission gear ring is also fixed on the outside of the rotating shaft seat. A reduction motor is fixed near the bearing seat inside the display stand, and a transmission gear is connected to the output shaft of the reduction motor. A synchronous chain is connected between the transmission gear and the transmission gear ring. A control box and a movable circular plate are also fixed inside the display stand, and a plurality of universal wheels are fixed to the outside of the bottom of the circular iron plate to contact and roll with the movable circular plate.

[0008] Preferably, an electromagnet seat is fixed on one side of the interior of the display stand, and the top of the electromagnet seat is close to the circular iron plate.

[0009] Preferably, the rotating shaft seat is inserted into the bottom end of the bearing seat and is fixed with a connecting shaft, the outside of the connecting shaft is fixedly connected with an insert, the bottom of the bearing seat is fixed with a connecting plate, the middle of the connecting plate is fixed with an angle sensor located inside the bearing seat, the outside of the angle sensor is fixed with a slot-type photoelectric switch through a hoop, and the output shaft of the angle sensor is fixedly connected to the connecting shaft.

[0010] Preferably, the slot-shaped photoelectric switch is used in conjunction with the insert for induction.

[0011] Preferably, a battery and a control circuit board are installed inside the control box, and the control circuit board is electrically controlled and connected to the battery, the reduction motor, the electromagnet seat, the angle sensor and the slot-type photoelectric switch.

[0012] Compared with the related art, the load-bearing turntable provided by the present invention has the following beneficial effects:

[0013] The utility model provides a rotating structure in which a reduction motor drives a transmission gear, and the transmission gear drives a transmission gear ring through a synchronous chain, so that the rotating shaft seat drives the circular iron plate to rotate on the bearing seat, and the placed shooting objects rotate along with it. The shooting personnel only need to stand in place to perform multi-angle shooting. When an emergency stop is required during the rotation process, the electromagnet seat is controlled to be energized, and the magnetic force of the electromagnet seat attracts the circular iron plate, thereby increasing the rotational resistance of the rotating circular iron plate, preventing the circular iron plate from shaking during rotation, and achieving a quick brake stop.

[0014] The utility model provides that during the rotation of the rotating shaft seat, the connecting shaft rotates accordingly, and each time the installed plug-in passes through the slot-shaped photoelectric switch, it is displayed that the starting point has been selected. In addition, during the rotation of the connecting shaft, the angle sensor detects the rotation angle information, and sends it to the external controller through the control circuit board to display the real-time angle on the display screen, so that the photographer can understand the shooting angle and choose a satisfactory angle for shooting.

[0021] Embodiment 1, by Figure 1-5 A load-bearing turntable is provided, comprising a display stand 1, universal wheels 2 being fixed to the four corners of the bottom of the display stand 1, a cavity being opened in the middle of the display stand 1, and a rotating structure 3 being fixedly installed in the cavity;

[0022] Specifically, the display stand 1 can be moved to a designated position via the universal wheel 1 2 , and the object to be photographed can be placed on the rotating structure 3 of the display stand 1 for rotational photography.

[0023] The rotating structure 3 includes a bearing seat 35 fixed in the middle of the display stand 1, a rotating shaft seat 33 is installed on the top of the bearing seat 35, a circular iron plate 31 is fixed on the top of the rotating shaft seat 33, and a transmission gear ring 331 is also fixed on the outside of the rotating shaft seat 33. A reduction motor 34 is fixed near the bearing seat 35 inside the display stand 1, and a transmission gear 341 is connected to the output shaft of the reduction motor 34. A synchronous chain 342 is connected between the transmission gear 341 and the transmission gear ring 331. A control box 37 and a movable circular plate 32 are also fixed inside the display stand 1. A plurality of universal wheels 311 are fixed to the outside of the bottom of the circular iron plate 31, which are in contact with and roll on the movable circular plate 32.

[0024] Specifically, the object to be photographed is placed on the circular iron plate 31, and then an instruction is sent to the control circuit board through an external controller. The control circuit board drives the reduction motor 34 to work, and the reduction motor 34 drives the transmission gear 341. The transmission gear 341 drives the transmission gear ring 331 through the synchronous chain 342, so that the rotating shaft seat 33 drives the circular iron plate 31 to rotate on the bearing seat 35, and the placed photographed object rotates with it. The photographer only needs to stand in place to take multi-angle photos. Moreover, during the rotation of the circular iron plate 31, it is assisted by multiple universal wheels 311 to move on the movable circular plate 32, thereby improving the rotation stability.

[0025] Among them, an electromagnet seat 36 is fixed on one side of the interior of the display stand 1, and the top of the electromagnet seat 36 is close to the circular iron plate 31; when an emergency stop is required during the rotation process, an instruction is sent to the control circuit board through the external controller, and the control circuit board drives the reduction motor 34 to stop working. When the control electromagnet seat 36 is energized, the electromagnet seat 36 magnetically attracts the circular iron plate 31, thereby increasing the rotation resistance of the rotating circular iron plate 31, preventing the circular iron plate 31 from shaking during rotation, and achieving a quick brake stop.

[0026] Example 2. On the basis of Example 1, the rotating shaft seat 33 is inserted into the bottom end of the bearing seat 35 and is fixed with a connecting shaft 332. The outside of the connecting shaft 332 is fixedly connected with an insert 3341. A connecting plate 351 is fixed to the bottom of the bearing seat 35. In the middle of the connecting plate 351, an angle sensor 333 is fixed inside the bearing seat 35. A slot-type photoelectric switch 334 is fixed to the outside of the angle sensor 333 through a hoop, and the output shaft of the angle sensor 333 is fixedly connected to the connecting shaft 332.

[0027] Specifically, during the rotation of the rotating shaft seat 33, the connecting shaft 332 rotates accordingly. Every time the installed plug-in 3341 passes through the slot-shaped photoelectric switch 334, the slot-shaped photoelectric switch 334 sends a signal to the control circuit board, and the control circuit board sends a signal to the external controller. The external controller sets a display screen, which shows that it has rotated to the starting point. In addition, during the rotation of the connecting shaft 332, the angle selection information is realized through the angle sensor 333, and the real-time angle is sent to the external controller through the control circuit board to display the real-time angle on the display screen, which makes it convenient for the photographer to understand the angle of his or her shooting and to choose a satisfactory angle for shooting.

[0028] Among them, the slot-type photoelectric switch 334 is used in conjunction with the plug-in piece 3341 for induction; a transmitting end and a receiving end are provided on both sides of the slot of the slot-type photoelectric switch 334. When the plug-in piece 3341 passes through the slot position of the slot-type photoelectric switch 334, the infrared ray sent by the transmitting end cannot be received by the receiving end, thereby sending a signal to the control circuit board, thereby reminding that it has rotated to the starting point.

[0029] In this embodiment, a battery and a control circuit board are installed inside the control box 37. The control circuit board is electrically connected to the battery, the reduction motor 34, the electromagnet seat 36, the angle sensor 333 and the slot-type photoelectric switch 334; the control circuit board is electrically connected to the external controller, and the external controller sends instructions to the control circuit board, and the control circuit board drives the electromagnet seat or the reduction motor to work.

[0030] Working principle:

[0031] The display stand 1 can be moved to a designated position through the universal wheel 1 2, and the object to be photographed is placed on the rotating structure 3 of the display stand 1, that is, on the circular iron plate 31. Then, an instruction is sent to the control circuit board through the external controller, and the control circuit board drives the reduction motor 34 to work. The reduction motor 34 drives the transmission gear 341, and the transmission gear 341 drives the transmission gear ring 331 through the synchronous chain 342, so that the rotating shaft seat 33 drives the circular iron plate 31 to rotate on the bearing seat 35, and the placed photographed object rotates with it. The photographer only needs to stand in place to take multi-angle photos. Moreover, during the rotation of the circular iron plate 31, multiple universal wheels 2 311 assist it to move on the movable circular plate 32, thereby improving the rotation stability. When an emergency stop is required during the rotation, an instruction is sent to the control circuit board through the external controller, and the control circuit board drives the reduction motor 34 to stop working. When the control electromagnet seat 36 is energized, the electromagnet seat 36 magnetically attracts the circular iron plate 31, thereby increasing the rotation resistance of the rotating circular iron plate 31, thereby achieving a quick brake stop, so that the photographed object can be quickly replaced.

[0032] During the rotation of the rotating shaft seat 33, the connecting shaft 332 rotates accordingly. Every time the installed plug-in piece 3341 passes through the slot-shaped photoelectric switch 334, the slot-shaped photoelectric switch 334 sends a signal to the control circuit board, and the control circuit board sends a signal to the external controller. The external controller sets a display screen, that is, it shows that it has rotated to the starting point. In addition, during the rotation of the connecting shaft 332, the angle sensor 333 detects the rotation angle information, and sends it to the external controller through the control circuit board to display the real-time angle on the display screen. The control circuit board sends the real-time angle to the external controller on the display screen, which makes it convenient for the photographer to understand the angle of his or her shooting and to choose a satisfactory angle for shooting.
