[0028] In order to better understand the technical content of the present application, specific embodiments are described below in conjunction with the accompanying drawings.

[0029] In conjunction with Figure 1 and Figure 2 shown, the first aspect of the present application proposes an electric restraint table for eye shooting of experimental animals, comprising a base 10, a Z-axis driving device 11, a connecting component 12, a Z-axis rotating component 13, a Y-axis rotating component 14 and a bearing table 20, the three-degree-of-freedom movement of the bearing table 20 is realized through the Z-axis driving device 11, the Z-axis rotating component 13 and the Y-axis rotating component 14, the height of the bearing table 20, the rotation along the Z-axis and the rotation attitude of the Y-axis can be changed.

[0030] Among them, the length direction of the base 10 is defined as the Y-axis direction, the width direction is defined as the X-axis direction, and the thickness direction is defined as the Z-axis direction, and the X-axis, Y-axis and Z-axis are perpendicular to each other.

[0031] It should be understood that the camera for shooting is arranged around the bearing table 20, and different directions can be selected according to different experimental animals, for example, for shooting animals such as experimental monkeys with both eyes in front of the face, the camera is arranged in front of the bearing table 20, i.e. in the extension direction of the Y-axis, for example, for shooting animals such as experimental mice or experimental rabbits with both eyes on the side of the face, the camera is arranged on one side of the bearing table 20, i.e. in the extension direction of the X-axis perpendicular to the Y-axis.

[0032] In this way, by controlling the height of the bearing table 20, the eye of the experimental animal is matched with the angle of view of the camera, by controlling the rotation of the bearing table 20 along the Z-axis and the Y-axis, different angles of the eye can be shot, and the switching of the left and right eyes can also be realized.

[0033] Specifically, the Z-axis driving device 11 is provided on the base 10, the connecting component 12 is connected to the Z-axis driving device 11, and the connecting component 12 can be driven by the Z-axis driving device 11 to produce displacement along the Z-axis relative to the base 10.

[0034] Further, the first end of the Z-axis rotating component 13 is connected to the connecting component 12, the Y-axis rotating component 14 is connected to the second end of the Z-axis rotating component 13, the Y-axis rotating component 14 can be driven by the Z-axis rotating component 13 to rotate around the Z-axis, and the bearing table 20 is connected to the output end of the Y-axis rotating component 14.

[0035] In the above embodiment, the base 10 is a plate structure with counterweight, and the connecting component 12 is configured as a strip structure.

[0036] Optionally, the Z-axis driving device 11 comprises a lead screw motor and a lead screw transmission mechanism, the lead screw motor and the lead screw transmission mechanism are arranged in a rectangular shell, the shell is provided with a sliding groove arranged along the Z-axis, the lead screw motor is arranged at the bottom, the lead screw transmission mechanism is arranged along the Z-axis, and the first end (the left end shown in the figure) of the connecting component 12 is connected to the sliding block of the lead screw transmission mechanism. Figure 1 When the lead screw motor drives the lead screw to rotate, the sliding block moves along the axis direction of the lead screw, and the connecting component slides up and down in the sliding groove to change the height position of the bearing table 20.

[0037] Further, the second end (the right end shown in the figure) of the connecting component 12 is connected to the Z-axis rotating component 13. Figure 1

[0038] Optionally, the Z-axis rotating component 13 comprises a Z-axis rotating motor and a first connecting structure arranged at the output end of the Z-axis rotating motor, the Y-axis rotating component 14 comprises a Y-axis rotating motor and a second connecting structure 24 arranged at the output end of the Y-axis rotating motor, the first connecting structure is fixedly connected with the Y-axis rotating motor, and the second connecting structure 24 is fixedly connected with the bearing table 20.

[0039] In the optional embodiment, the Z-axis driving motor and the first connecting structure are connected through a speed reducer, the transmission precision can be optimized, the angle of the bearing table 20 rotating along the Z-axis is more favorable to control, the Y-axis rotating motor and the second connecting structure 24 are connected through a worm gear transmission mechanism, the transmission has self-locking property, can be kept at a target angle, and the angle adjustment is accurate.

[0041] In the preferred embodiment, when the bearing table 20 rotates along the Y-axis, the eye of the experimental animal also appears displacement in the Z-axis direction, in order to compensate for the displacement and make the target eye always in the field of view of the camera, the lead screw motor and the Y-axis rotating motor are linked, that is, when the Y-axis rotating motor is controlled to rotate, the lead screw motor also rotates synchronously, the target eye moves in the Z-axis direction while rotating, and the target eye is always kept in the field of view of the camera. ​

[0042] Further, since the sizes of experimental animals are different, the height displacement of the eye is also different when the bearing table 20 rotates along the Y axis, so the linkage control of the Y axis rotation motor and the screw motor needs to match the rotation speeds of the two, specifically, different sensitivities can be set according to the size of the experimental animal, different gears are set according to common animals, for example, different gears are set for mice, rats, experimental rabbits or experimental monkeys respectively, each gear has a matching sensitivity, so that accurate adjustment can be realized when facing different shooting objects.

[0045] In this way, when the bearing table 20 rotates around the Z axis, the spatial displacement of the head is small, and more is the change of the angle, which is beneficial to the camera to observe the angle change of the eye of the experimental animal under the same visual angle.

[0046] In the preferred embodiment, since the torso part of the experimental animal is usually larger than the head, the width of the torso support area 202 is greater than the width of the head support area 201.

[0049] Further, the surface of the torso support area 202 is provided with a resistance increasing part 23. The resistance increasing part 23 can be selected as a plurality of protruding structures arranged on the torso support area 202.

[0050] In this way, the friction between the experimental animal and the torso support area 202 can be further increased, and the experimental animal and the bearing table 20 are relatively fixed.

[0053] Optionally, the water supply pipe is a hose, so that when the bearing table 20 moves, the sandwich layer can still be supplied with water.

[0055] Although the utility model has disclosed as above with preferred embodiments, it is not used to limit the utility model. Those skilled in the art without departing from the spirit and scope of the utility model can make various changes and decorations. Therefore, the protection scope of the utility model is defined by the claims.
