Description

TECHNICAL FIELD

[0001] The utility model relates to a shooting platform manufacturing technical field, specifically a kind of rotating mechanism of shooting platform. BACKGROUND

[0002] With the development of e-commerce and the progress of photography equipment, in order to better show the goods, 360° shooting is needed for the goods, if the photographer walks around the goods to complete 360° shooting, not only the work intensity is big, and the photographer is difficult to be consistent in shooting height each time, so the unity of the whole group of pictures cannot be guaranteed. The traditional rotating shooting platform is rotated manually, but it is difficult to ensure the uniformity of rotation.

[0003] The existing patent application No. CN202122947239.8 entitled "anti-shake surrounding rotating shooting platform" discloses a shooting platform, which comprises a support stage, a support base, a support main shaft, a rotating shooting support, a support support, and a driving assembly. The support stage and the support base are connected by the support main shaft. The rotating shooting support includes a first connection end and a second connection end. The first connection end is used to connect and install a shooting device. The second connection end of the rotating shooting support is movably connected with the support support. The support support is connected with the support base. The driving assembly is used to drive the rotating shooting support to rotate circumferentially around the support stage. The driving assembly drives the rotating shooting support to rotate circumferentially around the support stage, thereby realizing 360° shooting of the goods on the support stage. However, when a certain angle of the goods needs to be retaken, the rotating shooting support cannot rotate freely due to the resistance of the driving assembly and the driving device, and forced rotation may cause damage to the driving device. The goods can only be lifted, rotated by a certain angle, and then placed back on the support stage, but it cannot be guaranteed to return to the original position, resulting in poor unity between the retaken pictures and the original shooting pictures. Therefore, the existing rotating shooting platform needs to be further improved. UTILITY MODEL CONTENTS

[0041] In this embodiment, a first connecting hole 34a is radially arranged on the connecting ring 34, and a second connecting hole 1a is arranged at a corresponding position on the central shaft 1.

[0047] Working principle:

[0048] The rotating photographing platform has two functions of electric driving and manual driving, so as to meet various requirements of photographing.

[0049] Specifically, in the electric driving state, the bolt is inserted into the first connecting hole 34a and the second connecting hole 1a, so that the connecting ring 34 is connected with the central shaft 1 for transmission, the driving device 32 provides rotating power, the driving device 32 drives the first synchronous wheel 36a to rotate, the first synchronous belt 37a drives the second synchronous wheel 36b to rotate, so as to drive the transmission shaft 35 to rotate, and then the third synchronous wheel 36c on the transmission shaft 35 transmits the force to the transmission ring 33 through the second synchronous belt 37b; since the connecting ring 34 is connected with the central shaft 1 and the connecting ring 34 is fixed with the transmission ring 33 at this time, that is, the transmission ring 33 is fixed on the central shaft 1, due to the reciprocity of force, the force acting on the transmission ring 33 drives the base 31 to rotate around the central shaft 1, and further drives the rotating frame 2 to rotate around the central shaft 1.

[0050] In the manual driving state, the bolt is removed, the connecting ring 34 is separated from the central shaft 1, the central shaft 1 is separated from the connecting ring 34, so that the central shaft 1 can freely rotate without the resistance of the electric transmission structure, at this time, the central shaft 1 is only rotated, and further drives the object table 6 to rotate, or the object table 6 is directly manually rotated.

[0051] The above merely describes preferred embodiments of the present application, and is not intended to limit the implementation and protection scope of the present application. For those skilled in the art, it should be understood that any equivalent substitutions and obvious changes made according to the content of the present application and drawings should be included in the protection scope of the present application.
