[0037] This utility model provides a desktop photography cart, including a mainboard frame 1, roller assemblies 2, and a photography equipment connector 3. The mainboard frame 1 is detachably connected to the photography equipment connector 3 at its middle section. The roller assemblies 2 are rotatably connected to the ends of the mainboard frame 1, and a limiting member 4 is provided between the roller assemblies 2 and the mainboard frame 1. There are two roller assemblies 2, located at opposite ends of the mainboard frame 1. The lower end of the mainboard frame 1 is equipped with two roller assemblies 2, and the upper end of the mainboard frame 1 is equipped with a photography equipment connector 3 for connecting to relevant photography equipment. When the mainboard frame 1 is pushed forward, the turning angle of the roller assemblies 2 relative to the mainboard frame 1 can be adjusted by the limiting member 4, thus achieving turning. The roller assemblies 2 do not require a fixed guide rail and can roll on a flat surface, solving the technical problems of traditional carts that require a fixed rail for sliding, resulting in time-consuming deployment and the inability to change direction easily.

[0038] As an optional implementation, the roller assembly 2 includes a support frame 21, a fork frame 22, an outer wheel 23, and an inner wheel 24. There are two fork frames 22, two outer wheels 23, and two inner wheels 24. The two fork frames 22 are located at both ends of the support frame 21. The middle part of the fork frame 22 is rotatably connected to the end of the support frame 21. The outer wheel 23 and the inner wheel 24 are rotatably connected to both ends of the fork frame 22. The inner wheel 24 is not coaxial with the outer wheel 23 and is close to the support frame 21. That is, the inner wheel 24 and the outer wheel 23 are staggered. The middle part of the support frame 21 is rotatably connected to the end of the main board frame 1 through a rotating member 5, and the rotation angle between the support frame 21 and the main board frame 1 is limited by a limiting member 4.

[0039] As an optional implementation, the fork frame 22 includes a balance plate 221, a connecting shaft 222, an extension rod 223, a first connecting rod 224, and a second connecting rod 225. One end of the connecting shaft 222 is connected to the middle of the balance plate 221, and the connecting shaft 222 is connected to the end of the support frame 21 via a bearing. That is, the connecting shaft 222 extends into the connecting post 212 and is connected to the connecting post 212 via a bearing. One end of the balance plate 221 is connected to the end of the first connecting rod 224, the first connecting rod 224 passes through the inner wheel 24, and the first connecting rod 224 is rotatably connected to the inner wheel 24. The other end of the balance plate 221 is connected to... One end of the extension rod 223 is connected to the outer wheel 23, and the other end of the extension rod 223 is connected to the second connecting rod 225. The second connecting rod 225 passes through the outer wheel 23 and is rotatably connected to the outer wheel 23. The extension rod 223 is designed so that the outer wheel 23 and the inner wheel 24 are not on the same plane, so that their front and rear positions are staggered. When passing through the joint, one wheel can pass through first and the other wheel can pass through later, which can reduce the vibration at the joint. The first connecting rod 224 and the second connecting rod 225 are both located on the same side of the balance plate 221. The connecting shaft 222 and the first connecting rod 224 are located on both sides of the balance plate 221, respectively.

[0040] As an optional implementation, baffles are provided at the free ends of the connecting shaft 222, the first connecting rod 224, and the second connecting rod 225. The baffles are to prevent the outer wheel 23 from disengaging from the second connecting rod 225, the inner wheel 24 from disengaging from the first connecting rod 224, and the connecting shaft 222 from disengaging from the connecting post 212.

[0041] As an optional implementation, the support frame 21 has a U-shaped structure. The support frame 21 includes a support plate 211 and two connecting columns 212. The two connecting columns 212 are located at both ends of the support plate 211. The support plate 211 and the connecting columns 212 are connected by bolts. In order to facilitate disassembly and assembly, the connecting columns 212 are rotatably connected to the fork frame 22. By replacing the connecting columns 212 of different lengths, the height of the main board frame 1 from the ground can be changed.

[0042] As an optional implementation, the end of the support plate 211 is provided with a mating protrusion 2111, and the end of the connecting column 212 is provided with a mating groove 2121. The mating protrusion 2111 and the mating groove 2121 are mated to limit the support plate 211 and the connecting column 212, so as to prevent the support plate 211 and the connecting column 212 from separating or shifting during the forward movement of the desktop photography trolley.

[0043] As an optional implementation, a through hole 2112 is provided in the middle of the support plate 211, and a plurality of positioning holes 2113 are provided on the upper surface of the support plate 211. The plurality of positioning holes 2113 are arranged in an arc with the through hole 2112 as the center.

[0044] The motherboard frame 1 is provided with a connecting hole 11 and a limiting hole 12. The connecting hole 11 and the through hole 2112 are rotatably connected by a rotating component 5. That is, the support plate 211 will rotate relative to the motherboard frame 1 with the rotating component 5 as the center, thereby changing the turning angle of the roller assembly 2. The limiting hole 12 can be connected to the positioning hole 2113 at different positions through the limiting component 4. Connecting to the positioning hole 2113 at different positions will produce different turning angles. There can be multiple limiting holes 12, and one limiting hole 12 will correspond to multiple positioning holes 2113.

[0045] As an optional implementation, the rotating component 5 includes a fixed plate 51, a rotating shaft 52, and a nut 53. One end of the rotating shaft 52 is fixedly connected to the fixed plate 51, and the other end of the rotating shaft 52 passes through the through hole 2112 and the connecting hole 11 in sequence, with both the through hole 2112 and the connecting hole 11 being rotatably connected to the rotating shaft 52. The free end of the rotating shaft 52 is threadedly connected to the nut 53. The free end of the rotating shaft 52 is provided with a thread. When it is necessary to adjust the steering angle of the desktop photography trolley, the nut 53 needs to be loosened first, and then the limiting component 4 needs to be removed, so that the roller assembly 2 can be rotated. When the desired angle is reached, the limiting hole 12 is connected to the positioning hole 2113 at that position using the limiting component 4, and the nut is tightened at the same time, so that the nut and the fixed plate 51 clamp the support plate 211 and the main board frame 1, thereby restricting the rotation of the support plate 211.

[0046] As an optional implementation, the roller assembly 2 also includes a push rod 25 and a connecting plate 26. One end of the connecting plate 26 is bolted to the support frame 21, and the other end of the connecting plate 26 is rotatably connected to the end of the push rod 25. One push rod 25 connects two connecting plates 26. The push rod 25 is for the convenience of manually pushing the desktop photography cart.

[0047] As an optional implementation, the camera equipment connector 3 is a bowl or Michelin connector. The bowl can be 150mm or 100mm.

[0048] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
