Description

Easy-to-mount and dismount adjustable mounting device for marmoset shooting TECHNICAL FIELD

[0001] The present application relates to the technical field of scientific research instruments, and particularly relates to an easy-to-mount and dismount adjustable mounting device for marmoset shooting. BACKGROUND

[0002] Marmosets have unique value in the field of scientific research because they have a highly similar genetic background and physiological characteristics to humans, which makes them ideal model animals for studying human diseases. In a conventional laboratory environment, marmosets are generally in a caged state. In order to obtain their activity images, the common methods are: 1, placing a camera device at a certain place outside the monkey cage; 2, tightly attaching the camera device to the monkey cage, with the lens embedded between the grid gaps; 3, modifying the cage of the marmoset, removing part of the grid and replacing it with a transparent baffle, and the camera device outside the cage shoots the transparent part; 4, placing the marmoset in a transparent special monitoring cage for shooting.

[0003] The disadvantage of method 1 is that the external camera device is blocked by the grid of the cage, resulting in very low image quality, a large number of dead angles in real-time monitoring, and the collected video data being difficult to use for actual analysis. Method 2 solves the problem of grid blocking, but has strict limitations on lens size and is difficult to adjust the focal length, resulting in unclear imaging when the marmoset approaches and being unable to adjust the field of view. In addition, the marmoset will also touch, shake and even damage the device. Method 3 solves the problems of methods 1 and 2, but it requires more work and if the entire side is replaced with a transparent baffle, it may affect the natural activity of the marmoset (the marmoset cannot climb on this side), and it is also difficult to clean and maintain the cage. The disadvantage of method 4 is that marmosets are not suitable for long-term living in specially designed transparent cages, which results in, on the one hand, the experimenter having to spend a lot of effort on the marmoset for back-and-forth transportation, and on the other hand, being unable to conduct long-term monitoring or video recording.

[0028] Referring to FIG. 1, the embodiment of the present application provides a mounting device for easy installation and adjustment of marmoset shooting on a monkey cage observation window. The device includes a transparent baffle 1, a hanging rod and a shooting assembly 2. The transparent baffle 1 is arranged at the small window of the monkey cage observation window 7. The hanging rod includes a main rod 3 and a sub-rod 4, the main rod 3 is located on the upper surface of the monkey cage, and the tail end of the main rod 3 is hung on the monkey cage observation window 7 through the tail hook 5, the head end is suspended and located in front of the monkey cage observation window 7, and the middle part is clamped on the front surface of the monkey cage observation window 7 through the clamping piece 6. The sub-rod 4 is connected to the main rod 3, and the shooting assembly 2 is arranged on the sub-rod 4 and opposite to the transparent baffle 1. After the device is assembled, the activities of the marmoset within the lens field of view can be recorded.

[0029] The size of the transparent baffle 1 is matched with the size of the small window of the monkey cage observation window 7. In order to facilitate disassembly and cleaning, the transparent baffle 1 is inserted into the small window of the monkey cage observation window 7. Before installation, the grating plate of the small window in the monkey cage observation window 7 is removed, and the transparent baffle 1 of the same size is inserted. When cleaning is needed, it can be replaced at any time. Therefore, without greatly modifying the cage, the goal of eliminating the obstruction and obtaining high-quality images can be achieved. In addition, bittering agents can also be applied to the transparent baffle 1 to prevent the marmoset from continuously licking.

[0030] The auxiliary rod 4 comprises a vertical rod 41 and two horizontally arranged horizontal rods 42. The upper end of the vertical rod 41 is connected with the lower surface of the main rod 3. It should be noted that the vertical rod 41 can also be connected on the side surface of the main rod 3, and the specific connection mode can be selected according to the actual working condition, which is not limited here. The two horizontal rods 42 are both cantilever beams, one end of which is connected with the vertical rod 41, and the other end of which is suspended. The upper and lower ends of the shooting assembly 2 are respectively connected with the two horizontal rods 42. In order to facilitate the adjustment of the position of the shooting assembly 2, the main rod 3, the vertical rod 41 and the horizontal rod 42 are all provided with sliding grooves. Specifically, the main rod 3, the vertical rod 41 and the horizontal rod 42 are all metal pieces with four recessed grooves. The main rod 3 and the vertical rod 41, the vertical rod 41 and the two horizontal rods 42 are all connected through connecting frames. Therefore, the vertical rod 41 can slide forward and backward along the sliding groove of the main rod 3, the horizontal rod 42 can slide up and down along the sliding groove of the vertical rod 41, and the shooting assembly 2 can slide left and right along the sliding groove of the horizontal rod 42, so as to realize the forward and backward, left and right, and up and down position adjustment of the shooting assembly 2.

[0031] The tail hook 5 is in the shape of a "concave" character. The upper end of the tail hook 5 is connected with the upper surface of the main rod 3, and the lower end is hooked on the grid in the deep part of the monkey cage observation window 7, so as to prevent the main rod 3 from sliding forward. By rotating the tail hook 5, the angle between the main rod 3 and the monkey cage observation window 7 can also be adjusted.

[0032] The clamping piece 6 adopts a triangular clamping block. The upper surface of the triangular clamping block is detachably connected with the lower surface of the main rod 3 through a bolt, and the rear surface is abutted with the front surface of the monkey cage observation window 7. Therefore, it can play a role in stabilizing the whole, so that it will not slide forward and backward to cause the hook to loosen, and the angle relative to the observation window is also locked, so that the device will not swing left and right, and it is also convenient to disassemble and assemble.

[0033] The shooting assembly 2 comprises a camera. After the shooting assembly 2 is connected with a host computer or connected in a network, it can start monitoring and recording. A light shield can also be assembled on the transparent baffle 1 to eliminate reflection and improve the shooting quality.

[0034] The installation process of the embodiment of the present application is as follows:

[0035] The grid plate of the small window in the monkey cage observation window 7 is taken out and a transparent baffle 1 of the same size is installed. The main rod 3 is lifted to a certain angle with the horizontal plane, the tail hook 5 on the main rod 3 is hooked on a grid in the deep part of the upper rear part of the observation window, and the direction of the main rod 3 can be adjusted by rotating the angle of the screw of the tail hook 5. The main rod 3 is placed on the upper part of the observation window, and the triangular clamping block is clamped on the vertical surface of the front part of the observation window. After the auxiliary rod 4 is installed with the shooting assembly 2, the position of the shooting assembly 2 can be adjusted in the forward and backward and left and right directions. After the shooting assembly 2 is connected with a host computer or connected in a network, it can start monitoring and recording. A light shield can also be assembled on the transparent baffle 1 to eliminate reflection.

[0036] When the monkey cage needs to be changed or the device needs to be removed for component adjustment and replacement, the main rod 3 of the device can be lifted and then pushed backward to disengage the hook.

[0037] In summary, the embodiment of the present application is easy to combine and produce, and is very convenient to assemble and disassemble.
