Description

Technical Field

[0001] This application relates to the field of scientific research instrument technology, and in particular to an easily detachable and adjustable mounting device for photographing marmosets. Background Technology

[0002] Marmosets possess unique value in the scientific research field because they share a highly similar genetic background and physiological characteristics with humans, making them ideal model animals for studying human diseases. In a typical laboratory environment, marmosets are generally kept in cages. Common methods for obtaining images of their activities include: 1. Placing a camera device outside the cage; 2. Attaching a camera device tightly to the cage, with the lens embedded in the gaps in the grille; 3. Modifying the marmoset cage by removing part of the grille and replacing it with a transparent panel, with the camera outside the cage filming the transparent area; 4. Placing the marmoset in a transparent monitoring cage specifically designed for filming.

[0003] The disadvantages of Method 1 are: due to the structure of the monkey cage, the external camera device is obstructed by the cage's grille, resulting in very low image quality, numerous blind spots during real-time monitoring, and difficulty in using the collected video data for practical analysis. Method 2, while solving the grille obstruction problem, has strict limitations on lens size and difficulty in adjusting the focus, resulting in unclear imaging when marmosets approach and an inability to adjust the field of view. Furthermore, marmosets may touch, shake, or even damage the device. Method 3, while solving the problems of Methods 1 and 2, requires significantly more resources. Replacing an entire section with a transparent panel may affect the marmosets' natural activities (as they cannot climb on this side), and cage cleaning and maintenance are also difficult. The disadvantages of Method 4 are: since marmosets are not suited to living in specially designed transparent cages for extended periods, this would require researchers to expend excessive effort in transporting the marmosets back and forth, and would prevent long-term monitoring or video recording.

[0027] Reference Figure 1 This application provides an easily detachable and adjustable mounting device for filming marmosets on the observation window of a monkey cage. The device includes a transparent baffle 1, a hanging rod, and a filming assembly 2. The transparent baffle 1 is positioned at the small window of the monkey cage observation window 7. The hanging rod includes a main rod 3 and a secondary rod 4. The main rod 3 is located on the upper surface of the monkey cage, with its tail end hooked to the observation window 7 via a tail hook 5, its head suspended in the air and positioned in front of the observation window 7, and its middle section secured to the front surface of the observation window 7 via a snap-fit ​​6. The secondary rod 4 is connected to the main rod 3, and the filming assembly 2 is mounted on the secondary rod 4, directly opposite the transparent baffle 1. Once assembled, this device can record the activities of marmosets within the lens's field of view.

[0028] The size of the transparent baffle 1 is adapted to the size of the small window of the monkey cage observation window 7. For easy disassembly and cleaning, the transparent baffle 1 is inserted into the small window of the monkey cage observation window 7. Before installation, simply remove the grille of the small window inside the monkey cage observation window 7 and insert the transparent baffle 1 of the same size. It can be easily removed and replaced when cleaning is required. Thus, without significant modifications to the cage, the goal of eliminating obstructions and obtaining high-quality images can be achieved. Additionally, a bittering agent can be applied to the transparent baffle 1 to prevent the marmosets from continuously licking it.

[0029] The auxiliary rod 4 includes a vertical rod 41 and two horizontal rods 42 arranged vertically. The upper end of the vertical rod 41 is connected to the lower surface of the main rod 3. It should be noted that the vertical rod 41 can also be connected to the side of the main rod 3; the specific connection method can be selected according to the actual working conditions and is not limited here. Both horizontal rods 42 are cantilever beams, with one end connected to the vertical rod 41 and the other end suspended. The upper and lower ends of the shooting component 2 are respectively connected to the two horizontal rods 42. To facilitate the adjustment of the position of the shooting component 2, the main rod 3, the vertical rod 41, and the horizontal rods 42 are all provided with sliding grooves. Specifically, the main rod 3, the vertical rod 41, and the horizontal rods 42 are all made of metal parts with four-sided grooves. The main rod 3 is connected to the vertical rod 41, and the vertical rod 41 is connected to the two horizontal rods 42 via connecting brackets. Thus, the vertical rod 41 can slide back and forth along the groove of the main rod 3, the horizontal rods 42 can slide up and down along the groove of the vertical rod 41, and the shooting component 2 can slide left and right along the groove of the horizontal rod 42, thereby realizing the adjustment of the shooting component 2 in the front-back, left-right, and up-down positions.

[0030] The tail hook 5 is U-shaped. The upper end of the tail hook 5 is connected to the upper surface of the main rod 3, and the lower end is hooked on the grid deep inside the monkey cage observation window 7 to prevent the main rod 3 from sliding forward. The angle between the main rod 3 and the monkey cage observation window 7 can also be adjusted by rotating the tail hook 5.

[0031] The locking component 6 uses a triangular locking block. The upper surface of the triangular locking block is detachably connected to the lower surface of the main rod 3 by bolts, and the rear surface abuts against the front surface of the monkey cage observation window 7. This stabilizes the entire structure, preventing it from sliding back and forth and causing the hook to loosen. The angle relative to the observation window is also locked, preventing the device from swinging left and right, and facilitating disassembly and assembly.

[0032] The shooting component 2 includes a camera. Once the shooting component 2 is connected to the network or the host, it can start monitoring and recording. A light shield can also be attached to the transparent baffle 1 to eliminate reflections and improve the shooting quality.

[0033] The installation process of this embodiment is as follows:

[0034] Remove the grid panel from the small window inside the monkey cage observation window 7 and install a transparent baffle 1 of the same size. Raise the main pole 3 to a certain angle with the horizontal plane, and hook the tail hook 5 on the main pole 3 onto a grid bar deep in the upper rear of the observation window. The direction of the main pole 3 can be adjusted by loosening the screw of the tail hook 5 and rotating its angle. Place the main pole 3 horizontally on the upper part of the observation window, and at the same time, lock the triangular block in place on the front vertical surface of the observation window. After the secondary pole 4 is equipped with the shooting component 2, its position can be adjusted in both forward and backward and left and right directions. After the shooting component 2 is connected to the network or the host, monitoring and recording can begin. A light shield can be installed on the transparent baffle 1 to eliminate reflections.

[0035] When the monkey cage needs to be cleaned or the device needs to be removed for component adjustment or replacement, the main rod 3 of the device can be lifted and then pushed backward to disengage the hook.

[0036] In summary, the embodiments of this application are easy to assemble and manufacture, and are very convenient to load and unload. They effectively solve a series of problems caused by grid obstruction during previous shooting, effectively improve the quality of image data, and do not affect the breeding and daily activities of marmosets, nor cause harm to the marmosets' bodies. They can save a lot of manpower, efficiently acquire a large amount of data, and can be used to monitor the health status of marmosets and collect the image data required for behavioral analysis.

[0037] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
