[0042] In a typical implementation of the present invention, Figure 1As shown, a 360° annular shooting device with an adjustable rotation radius around a center point is proposed, which is composed of a shooting adjustment device 1, a track running device 2, a radius adjustment device 3 and a rotation radius fixing device 4. The shooting adjustment device 1 and the radius adjustment device 3 are both fixed to the track running device 2, and the rotation radius fixing device 4 is provided on the radius adjustment device 3.

[0043] Among them, the track running device 2 is composed of a wheel 201, a connecting rod 202 and an axle 203. The axle 203 is a square wooden square with a size of 500×40×40mm. Both ends of the axle 203 are connected to the wheel 201. The wheel 201 is a patterned rubber tire with a thickness of 25mm and a diameter of 60mm. There are two cylindrical holes 204 with a depth of 30mm and a diameter of 10mm on the top surface of the axle 203. The center distance between the two holes is 100mm. The outermost hole is for the connecting rod 202 to be inserted, and the inner hole is for the radius adjustment device 3 to be inserted. The connecting rod 202 is a wooden square with a size of 1000×50×50mm. There is a pin connecting the two axles on its bottom surface. It is a cylinder with a length of 30mm and a diameter of 10mm. When in use, just insert the pin into the cylindrical hole reserved for the axle. The components are connected by plug-in type, which is convenient for installation, disassembly and testing.

[0044] Two axles 203 are provided, and the two axles 203 form a certain angle in space, such as Figure 3 As shown, the axes of the two axles 203 are at an acute angle. One end of the two axles 203 is connected by a connecting rod 202. When connecting, the pin at the bottom of the connecting rod 202 is inserted into the hole of the axle 203. The connecting rod 202 and the axle 203 form an articulated form.

[0045] Among them, the shooting adjustment device 1 is composed of a clamping member 101, a connecting arm 102 and a height adjustment rod 103. The connecting arm 102 is arranged horizontally, and the height adjustment rod 103 is arranged vertically. The height adjustment rod 103 is slidably connected to one end of the connecting arm 102, and the other end of the connecting arm 102 is fixedly connected to the clamping member 101.

[0046] Specifically, the clamping member 101 is in the form of a clamping claw, and the clamping member 101 is connected to the end of the connecting arm 102, and the angle between the two can be adjusted, that is, the clamping member 101 can be fixed to the end of the connecting arm 102 at different angles, thereby adjusting the angle of the camera or other shooting equipment clamped by the clamping member 101. The camera or the like can be fixed to the entire annular shooting device through the shooting adjustment device 1, so as to achieve a more stable shooting effect.

[0047] The height adjustment rod 103 is composed of a long wooden rod, and a sliding track 104 is provided inside the rod. The connecting arm 102 is connected to the sliding track 104 and can slide up and down in the sliding track 104 to change the height of the camera held by the clamping member. The end of the connecting arm 102 is always kept perpendicular to the height adjustment rod. The height adjustment rod can be replaced according to actual needs, and the height can be set to 100mm to 2000mm to adjust the height of the camera. A fastening bolt 105 is provided on the rear side of the height adjustment rod. The fastening bolt 105 is fixedly connected to the connecting arm 102, and the height of the connecting arm can be locked to make the shooting process more stable.

[0048] The bottom of the height adjustment rod 103 is fixed to the center position of the top of the connecting rod 202 of the track running device 2 .

[0049] Among them, the radius adjustment device 3 is composed of a rack 301 and a rotating gear 302. Two racks 301 are set, and the two racks are arranged opposite to each other and at an interval. The same rotating gear 302 is set between the two racks. The rotating gear 302 is meshed with both racks 301. The position of the rack can be adjusted by rotating the rotating gear.

[0050] One end of one rack 301 is hinged to one axle of the track running device 2, and the other rack 301 is hinged to the other axle of the track running device 2. The rack 301 is parallel to the connecting rod 202, and a latch 303 is provided at one end of the rack 301, and the latch 303 is inserted into the hole of the axle 203.

[0051] The two racks 301 are provided with positioning rails 304 along their length directions, and positioning rods 305 are arranged at the other ends of the two racks 301. The positioning rods 305 are perpendicular to the racks 301, and one end of the positioning rod 305 is fixed to the end of one of the racks 301, and the other end of the positioning rod 305 is slidably connected to the positioning rail 304 of the other rack 301. The positioning rail constrains the positioning rod, so that the two racks can constrain each other, and the parallelism and stable operation of the two racks can be achieved.

[0052] In this embodiment, the rack is made of a wooden block, and straight teeth are fixed on the inner side of the wooden block to form the rack.

[0053] In a further solution, a perforated wooden board 205 is fixedly provided on the connecting rod 202, and the rotating gear 302 is installed in the hole of the perforated wooden board, which can limit the left and right displacement of the rotating gear, and the rotating gear can move forward and backward in the hole of the perforated wooden board.

[0054] Among them, the rotation radius fixing device 4 is fixed on the radius adjustment device 3, and the rotation radius fixing device 4 is composed of a U-shaped steel 401 and a rotating bolt rod 402. The U-shaped steel 401 is buckled on the top of the two racks 301 of the radius adjustment device 3, and the two sides of the U-shaped steel 401 are respectively attached to the side of the two racks and connected through the rotating bolt rod 402. The rotating bolt rod 402 connects the side of the U-shaped steel 401 with the side of the rack. Before use, loosen the rotating bolt rod to adjust the radius adjustment device. After the adjustment is completed, tighten the rotating bolt rod. By fixing the rotating bolt rod, the distance between the two axles can be fixed, and the size of the rotation radius is fixed.

[0055] The device is made of wood, wood boards and other materials, which is easy to make, the material selection is convenient and the cost is low.

[0056] The working principle of the ring-shaped camera is as follows:

[0057] When using the device, assemble the trajectory running device 2 and the radius adjusting device 3 together, calculate the length of the radius adjusting device 3 according to the distance of the required object to be photographed, and after adjusting the length of the radius adjusting device 3, place the rotating radius fixing device 4 on the radius adjusting device 3, and tighten the rotating bolt rod 402 to securely fix the length of the radius adjusting device 3.

[0058] H is the distance from the camera to the center point of the shooting, that is, the ring shooting radius. Since the shooting adjustment device 1 is located at the center of the connecting rod 202, when the radius adjustment device is adjusted, the contraction or extension distance of the two axles is the same, so the shooting center point is always located at the intersection of the two axle axes. The distance from the two ends of the connecting rod 202 to the shooting center point is set to R, the length of the connecting rod is 1000mm, the distance between the end of the radius adjustment device 3 and the end of the connecting rod 202 is 100mm, and the length of the radius adjustment device 3 is set to S. According to the principle of similar triangles, the following formula is obtained:

[0059]

[0060] The distance from the shooting center point to the midpoint of the connecting rod is (H+150) mm. According to the Pythagorean theorem of triangles, the following calculation formula is available:

[0061] R 2 -500 2 =(H+150) 2 ;

[0062] According to the above formula, we can deduce

[0063] Finally,

[0064] According to the required length H, the length of S can be obtained by calculation. On the radius adjustment device 3, the rotating gear 302 is turned to adjust the length of S, and then the U-shaped steel 401 is placed on the radius adjustment device 3, and the rotating bolt rod 402 is tightened to fix the length of the radius adjustment device 3. By adjusting the length S of the radius adjustment device 3, the angle between the two axles 203 changes, and the distance H from the camera to the center point of the shooting can be adjusted, that is, the ring shooting radius is changed. When the volume of the object to be photographed is large, it is necessary to adjust a larger diameter to adjust the ring shooting radius; for small objects, the smaller the ring shooting radius, the more accurate it is; therefore, the ring shooting radius is adjusted according to the size of the object to be photographed.

[0065] Place the camera on the clamping member 101 of the photographing adjustment device 1, adjust the angle, and then take photos.

[0066] The wheel 201 rotates to drive the entire device to rotate with the intersection of the two axle axes as the center point, so as to perform 360° circular shooting.

[0067] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
