Description

Technical Field

[0001] This utility model relates to the field of shooting fixture technology, and in particular to a plant leaf modeling shooting fixture that can rotate at multiple angles. Background Technology

[0002] In the fields of 3D modeling, morphological research, and high-definition imaging of plant leaves, it is often necessary to perform complex spatial pose adjustments on the leaves to obtain multi-angle data. Existing adjustment devices generally suffer from insufficient degrees of freedom and low adjustment accuracy.

[0003] Traditional clamps often rely on a single rotating axis or a simple lifting structure, which can only achieve basic adjustments such as height or planar rotation. They cannot simultaneously control the blade pitch angle (forward and backward tilt angle), horizontal yaw angle (left and right tilt angle), and circumferential orientation. This results in repeated disassembly and reassembly of the blade when shooting at complex angles, which is inefficient. Although some devices attempt to combine multiple rotating nodes, each node lacks an independent locking mechanism. After fine adjustment, it is easy to shift due to its own weight or external force. Moreover, the motion coupling between nodes is strong, making it difficult to achieve precise independent control of the attitude. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a plant leaf modeling and shooting fixture that can rotate at multiple angles.

[0005] The technical solution is as follows: A multi-angle rotatable plant leaf modeling and photography fixture, comprising a support adjustment component, a support frame, a lifting plate, a first rotating plate, a second rotating plate, a threaded cylinder, a mounting block, a leaf clamp, and a fastening component. The support adjustment component serves as the main support of the device, with the support frame fixed on it. A lifting plate is vertically slidably connected inside the support frame. The upper end of the lifting plate is rotatably connected to the first rotating plate, and the upper end of the first rotating plate is rotatably connected to the second rotating plate. The first and second rotating plates together constitute a multi-node horizontal rotation adjustment mechanism of the device. A threaded cylinder is connected to the top of the second rotating plate, and a mounting block is rotatably connected to the left end of the threaded cylinder. A leaf clamp is mounted on the mounting block, and a fastening component is provided on the support frame.

[0006] As an improvement to the above solution, the blade clamp is composed of a clamping arm, including an operating end and a clamping end. The upper ends of the two are rotatably connected by a connecting shaft. A torsion spring is sleeved on the connecting shaft, and its two ends are fixed to the operating end and the clamping end respectively.

[0007] As an improvement to the above solution, the support adjustment assembly includes a base and a slider. An annular groove is provided on the outer periphery of the top of the base, the slider is slidably connected to the annular groove, and the support frame is horizontally rotatably connected to the top of the slider.

[0008] As an improvement to the above solution, the fastening assembly includes a first locking bolt, a second locking bolt, a third locking bolt, and a fourth locking bolt. The first locking bolt is threaded through to the upper right side of the support frame, and its end face is in contact with the wall of the lifting plate. The second locking bolt is rotatably threaded through to the upper front side of the lifting plate. A threaded hole is provided on the first rotating plate at the position corresponding to the second locking bolt, and the second locking bolt is screwed into the threaded hole to lock the position of the first rotating plate. The third locking bolt is rotatably threaded through to the upper front side of the first rotating plate. A threaded hole is provided on the second rotating plate at the position corresponding to the third locking bolt, and the third locking bolt is screwed into the threaded hole to lock the position of the second rotating plate. The fourth locking bolt is threaded through to the threaded cylinder, and its left end is tightly fitted to the wall of the mounting block.

[0009] As an improvement to the above solution, it also includes a universal joint and lighting fixtures. There are two lighting fixtures, which are movably mounted on both sides of the mounting block via the universal joint.

[0010] As an improvement to the above solution, it also includes suction cups, with three suction cups evenly installed on the bottom of the base.

[0011] This utility model has the following advantages: 1. Height is adjusted by lifting plate; horizontal tilt angle adjustment is achieved by first and second rotating plates at multiple nodes; pitch angle is adjusted by mounting block; circumferential orientation is adjusted by the rotation of support frame; and circumferential position is adjusted by sliding slider in an annular groove. Multi-level linkage covers all degrees of freedom such as height, tilt angle, orientation, and position, meeting the requirements for precise positioning in any posture.

[0012] 2. The blade clamp utilizes the elastic force of a torsion spring to automatically close and hold the blade rootstock, making installation and removal convenient and secure. The first to fourth locking bolts respectively lock the lifting plate, the first rotating plate, the second rotating plate, and the mounting block, ensuring a stable position after adjustment. The damping medium between the support frame and the slider ensures smooth circumferential adjustment and stepless self-locking.

[0013] 3. The front and rear lights on the mounting block are multi-directionally adjustable via a ball joint structure with a universal joint, providing flexible supplementary lighting for the blades and optimizing shooting results. Three suction cups on the bottom of the base provide strong adhesion, firmly fixing the device to a smooth surface, effectively resisting operational interference and ensuring high-precision operation stability.

Detailed Implementation

[0019] Example: A multi-angle rotatable plant leaf modeling and photography fixture, such as... Figures 1-4 As shown, the device includes a support adjustment assembly, a support frame 3, a lifting plate 5, a first rotating plate 7, a second rotating plate 9, a threaded cylinder 10, a mounting block 11, a blade clamp 13, and a fastening assembly. The support adjustment assembly serves as the main support for the device, with the support frame 3 fixed on it. The lifting plate 5 is vertically slidably connected inside the support frame 3, allowing for height adjustment along the support frame 3 to achieve overall height adjustment of the device. The upper end of the lifting plate 5 is rotatably connected to the first rotating plate 7 via a pin, and the upper end of the first rotating plate 7 is rotatably connected to the second rotating plate 9 via a pin. The first rotating plate 7 and the second rotating plate 9 together constitute a multi-node horizontal rotation adjustment mechanism for the device. The top of the second rotating plate 9 is connected to the threaded cylinder 10, and the left end of the threaded cylinder 10 is rotatably connected to the mounting block 11 via a pin, allowing... Mounting block 11 can be rotated around the pivot pin to adjust the pitch direction. A leaf clamp 13 is mounted on mounting block 11. The leaf clamp 13 is composed of clamping arms, including an operating end (pinching part) and a clamping end (clamping part). The upper ends of the two are rotatably connected by a connecting shaft. A torsion spring is sleeved on the connecting shaft, and its two ends are fixed to the operating end and the clamping end respectively. In the natural state, the elastic force of the torsion spring drives the clamping end to remain closed. When the operating end is pinched, the clamping arm rotates around the connecting shaft, the torsion spring undergoes torsional deformation and stores elastic potential energy. After the plant leaf and root are placed between the clamping arms, the operating end is released, the torsion spring releases potential energy to drive the clamping arm to return to its original position, and the clamping end clamps the leaf. Subsequently, the height, spatial tilt angle and orientation of the leaf can be precisely adjusted by the multi-degree-of-freedom adjustment mechanism of the device. The support frame 3 is equipped with fastening components.

[0020] like Figure 1 , Figure 2 and Figure 4As shown, the support adjustment assembly includes a base 1, a slider 2, and suction cups 17. An annular groove 101 is provided on the outer periphery of the top of the base 1. The slider 2 is slidably connected to the annular groove 101. The support frame 3 is horizontally rotatably connected to the top of the slider 2. A damping medium is provided at the rotatable connection between the two. The support frame 3 remains stable without external force. Applying force to push the support frame 3 can make it rotate around the axis of the slider 2 to adjust the circumferential orientation of the plant leaves on it. At the same time, the entire device can be moved circumferentially along the annular groove 101 by the slider 2 to realize the position and orientation adjustment of the device within the circumferential area, enhancing the multi-point adjustment capability. Three suction cups 17 are evenly installed on the bottom of the base 1. Using the adsorption force generated by the suction cups 17, the base 1 can be firmly fixed to the table or the ground to ensure the overall stability of the device during use.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, the fastening assembly includes a first locking bolt 4, a second locking bolt 6, a third locking bolt 8, and a fourth locking bolt 12. The first locking bolt 4 is threadedly connected to the upper right side of the support frame 3. The end face of the first locking bolt 4 abuts against the wall surface of the lifting plate 5 to lock the position of the lifting plate 5. Loosening the first locking bolt 4 releases the lock on the lifting plate 5, allowing its height to be adjusted along the support frame 3. The second locking bolt 6 is rotatably connected to the upper front side of the lifting plate 5. A threaded hole is provided on the first rotating plate 7 at a position corresponding to the second locking bolt 6. Screwing the second locking bolt 6 into this threaded hole locks the position of the first rotating plate 7. Unscrewing the second locking bolt 6 allows the first rotating plate 7 to rotate horizontally around the pivot pin on the lifting plate 5. The blades are adjusted by rotation. The first rotating plate 7 is rotatably connected to the upper front side with a third locking bolt 8. The second rotating plate 9 has a threaded hole corresponding to the third locking bolt 8. After the third locking bolt 8 is screwed into the threaded hole, the position of the second rotating plate 9 is locked. The operation and function of the third locking bolt 8 are the same as those of the second locking bolt 6, used to lock or release the second rotating plate 9. The threaded cylinder 10 is internally threaded with a fourth locking bolt 12. The left end of the fourth locking bolt 12 is tightly fitted to the wall of the mounting block 11. Loosening the fourth locking bolt 12 can release the locking of the mounting block 11, allowing it to rotate in the pitch direction around the pivot pin at the left end of the threaded cylinder 10. Tightening the fourth locking bolt 12 locks the position of the mounting block 11.

[0022] like Figure 1 and Figure 3As shown, it also includes a universal joint 15 and two lighting lamps 16. The lighting lamps 16 are provided and are movably mounted on the front and rear sides of the mounting block 11 via the universal joint 15. Specifically, the front and rear end faces of the mounting block 11 are provided with spherical movable grooves, and the inner ends of the two lighting lamps 16 are also provided with spherical movable grooves. The universal joint 15 consists of a long rod and spheres fixed at both ends. The sphere at one end of the universal joint 15 is connected to the movable groove of the lighting lamp 16 by a ball joint, and the sphere at the other end is connected to the movable groove on the end face of the mounting block 11 by a ball joint, thereby realizing the flexible adjustment of the illumination angle of the lighting lamps 16. When displaying or photographing plant leaves, turning on the lighting lamps 16 can provide supplementary lighting for the leaves.
