[0003] Traditional capture and stress restraint methods often cause strong fear and stress reactions in marmosets, which not only affects the experimental results but may also cause long-term damage to the marmosets' mental health.

[0004] The patent application with publication number CN107157610A discloses an integral lifting and adjusting restraint chair for experimental monkeys, which mainly solves the problems in the prior art that the existing restraint chairs have a narrow scope of use, cause additional harm to the experimental subjects, and cause deviations in the experimental results.

[0033] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the drawings in the specification.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present application, but the present application may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present application. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0036] Example 1

[0037] This is the first embodiment of the present application, which provides a non-capturing stress-induced marmoset restraint device.

[0038] Specifically, refer to Figure 1 and Figure 2 The main body assembly 100 includes a monkey chair body 101, a monkey chair card plate 102 disposed at the end of the monkey chair body 101, and a front baffle 103 and a rear baffle 104 disposed on the outer wall of the monkey chair body 101;

[0039] A lifting assembly 200 is arranged on the inner wall of the monkey chair body 101, and the lifting assembly 200 includes a lifting base 201, a lifting plate 202 is arranged at the end of the lifting base 201, and a moving part is arranged at the end of the lifting plate 202;

[0040] The moving part is connected to the adjusting part arranged on the outer wall of the monkey chair body 101. The adjusting part includes a transmission part and an adjusting part. The transmission part is used to drive the moving part to move inside the lifting base 201. The adjusting part is used to change the lifting state of the lifting plate 202.

[0041] The lifting base 201 is installed inside the monkey chair body 101, and a front baffle 103 and a rear baffle 104 are respectively arranged on the outside of the monkey chair body 101, and are installed on the outside of the monkey chair body 101 by a quick fixing method.

[0042] When in use, the monkey chair body 101 is docked with the transport cage used to transport marmosets, and the front baffle of the transport cage is docked with the rear baffle 104 of the monkey chair body 101. The experimental animal, such as a marmoset, is pushed from the transport cage into the interior of the monkey chair body 101 by pushing the push plate, so that it falls onto the top of the lifting base 201. The push plate effectively avoids the animal stress caused by catching with gloves.

[0043] After the marmoset enters the interior of the monkey chair body 101 , the state of the marmoset inside can be observed through the observation hole 1011 on the surface of the monkey chair body 101 .

[0044] The moving parts inside the lifting base 201 are driven by the adjusting parts outside the monkey chair body 101. The moving parts are associated with the lifting plate 202. The lifting plate 202 is driven to rise and fall above the lifting base 201 by the moving parts. After the marmoset enters the monkey chair body 101, the moving parts are driven by the adjusting parts to make the lifting plate 202 rise inside. The marmoset rises with the lifting plate 202 and exposes its head from the fixing hole 1012 at the top. After the head of the animal is exposed, the neck of the marmoset is clamped and fixed by the monkey chair clamping plate 102. During the rising process, a protective cover is placed on the top of the monkey chair body 101 to prevent the marmoset from escaping.

[0045] Example 2

[0046] This is the second embodiment of the present application, and this embodiment is implemented based on the previous embodiment.

[0047] Specifically, refer to Figure 2 to Figure 4 The lifting plate 202 is located in an inner chamber 2011 opened at the end of the lifting base 201. A straight rod 2012 is hinged at the end of the lifting base 201 and the end of the straight rod 2012 away from the lifting base 201 is hinged to the end of the lifting plate 202. A connecting plate 2021 is fixed to the end of the lifting plate 202 and a sliding groove 2022 is opened on the outer wall of the connecting plate 2021, and the end of the straight rod 2012 cooperates with the sliding groove 2022.

[0048] Among them, the straight rod 2012 is hinged inside the lifting base 201, and the other end is hinged to the connecting plate 2021 on the bottom surface of the lifting plate 202. The two groups of straight rods 2012 cooperate to control the lifting plate 202 to rise and fall on the upper surface of the lifting base 201.

[0049] Preferably, the moving part includes a threaded rod 204, a driving gear 2041 is provided at the end of the threaded rod 204, and the driving gear 2041 extends into the connecting block 203 at the end of the lifting base 201, and a reduction gear set 2031 is provided on the inner wall of the connecting block 203 and meshes with the driving gear 2041. The reduction gear set 2031 is also connected to the transmission member, and is driven by the transmission member to drive the threaded rod 204 to rotate inside the lifting base 201. When the threaded rod 204 rotates, it drives the straight rod 2012 to move to adjust the height of the lifting plate 202.

[0050] Among them, a movable block is arranged on the surface of the threaded rod 204 and is connected to the bottom of the straight rod 2012. When the threaded rod 204 rotates, the movable block moves back and forth on the surface of the threaded rod 204 to drive the bottom of the straight rod 2012 to move. Since the bottom end of the other straight rod 2012 is hingedly fixed to the surface of the lifting base 201, the other end slides inside the slide groove 2022. Figure 2 As shown, when the lifting plate 202 rises, the end of the straight rod 2012 slides from right to left inside the sliding groove 2022.

[0051] The connecting block 203 is fixed on the upper surface of the lifting base 201, and the top end of the threaded rod 204 is located inside the connecting block 203 and meshes with the internal reduction gear set 2031. Figure 4 As shown, the reduction gear set 2031 inside the connecting block 203 is driven by the transmission member to move, and at the same time, the rotation of the transmission member is reduced by the reduction gear set 2031 and transmitted to the threaded rod 204, so that the rotation speed of the threaded rod 204 is reduced, which is further used to slow down the speed of the lifting plate 202 when it is lifted and lowered inside the monkey chair body 101, thereby avoiding the marmoset from having a stress response due to the fast lifting speed or the pause at the end of the rapid lifting.

[0052] Example 3

[0053] This is the third embodiment of the present application, and this embodiment is implemented based on the previous embodiment.

[0054] Specifically, refer to Figures 5 to 8 The regulating component includes a driver 301, an inner plate 302 is provided at the inner wall end of the driver 301, and an air hole 3021 is opened on the end surface of the inner plate 302, and adjacent inner plates 302 form a cavity 3022 for air flow.

[0055] Among them, the driver 301 is fixed on the outside of the monkey chair body 101, and a connecting pipe is provided at the bottom of the driver 301 to connect with the compressed gas tank. Compressed gas is transported to the inside of the driver 301 through the compressed gas tank as a power source to avoid the motor's internal mechanical structure from generating large noise and vibration during operation, causing additional stress stimulation to the marmoset.

[0056] A plurality of inner plates 302 are arrayed at the bottom of the driver 301 , and air holes 3021 are opened on the surface of the inner plates 302 , through which the gas inside the cavity 3022 is discharged.

[0057] Preferably, refer to Figure 5 and Figure 6 An elastic membrane 303 is fixed to the inner wall of the driver 301 and a moving block 304 is arranged at the axis of the elastic membrane 303. The moving block 304 moves along with the elastic membrane 303 on the inner wall of the driver 301. A column 3041 is fixed to the end of the driver 301 to push the ball 3024 arranged at the end of the driver 301 downward. When the ball 3024 moves downward, it squeezes the first elastic member 3023 and opens a channel for compressed gas to enter and blow the elastic membrane 303. The elastic membrane 303 drives the moving block 304 to move upward inside the driver 301.

[0058] The elastic membrane 303 and the moving block 304 at the axis center divide the interior of the driver 301 into upper and lower sides, and a compressed gas tank connected to the bottom of the driver 301 delivers gas to the interior of the driver 301 .

[0059] In the initial state, the elastic membrane 303 and the middle moving block 304 are in a horizontal state, and the column 3041 below the moving block 304 resists the ball 3024 to make it downward and squeeze the first elastic member 3023. At this time, the air inlet channel at the bottom of the driver 301 is opened, and when gas enters, the gas fills the interior of the cavity 3022 and blows the elastic membrane 303 to deform upward. While the elastic membrane 303 moves upward, it will also drive the moving block 304 upward. At this time, the ball 3024 loses the resistance of the column 3041, and is deformed and moves upward by the first elastic member 3023 to block the air inlet channel. At this time, the gas stops entering, and the internal gas is discharged through the air hole 3021. The elastic membrane 303 recovers its deformation and drives the moving block 304 to move downward, and the column 3041 at the bottom pokes the ball 3024 downward again to open the air inlet channel, so that the elastic membrane 303 drives the moving block 304 to move up and down in the internal cycle of the driver 301.

[0060] A swing rod 3042 is hinged at the end of the moving block 304, and the other end of the swing rod 3042 is connected to the first bevel gear 401 arranged on the inner wall of the driver 301. An output shaft 4011 is fixed to the end face of the first bevel gear 401 and the end of the swing rod 3042 is sleeved on the outer wall of the output shaft 4011. The first bevel gear 401 is driven to rotate on the inner wall of the driver 301 through the swing rod 3042.

[0061] Among them, the swing arm 3042 is hinged at the upper inner part of the moving block 304, and the other end is sleeved on the outside of the output shaft 4011. The output shaft 4011 is fixed on the surface of the first bevel gear 401 and is not located at the axis center. When the compressed gas stops being delivered, the elastic membrane 303 and the middle moving block 304 are in a horizontal state. At this time, the output shaft 4011 hinged by the swing arm 3042 is located at the bottom of the first bevel gear 401.

[0062] When compressed gas is delivered into the driver 301, the elastic membrane 303 drives the moving block 304 to move upward. At the same time, the swing rod 3042 on the surface of the moving block 304 moves together, and at the same time, the first bevel gear 401 is driven to rotate inside the driver 301 through the output shaft 4011. The elastic membrane 303 drives the moving block 304 to complete a lifting cycle, and the first bevel gear 401 is driven to rotate one circle through the output shaft 4011.

[0063] Reference Figure 4 and Figure 5 A second bevel gear 403 is also provided on the inner wall of the driver 301 and the second bevel gear 403 is meshed with the first bevel gear 401. A second rotating shaft 4031 is provided at the axis of the second bevel gear 403 and the end of the second rotating shaft 4031 extends to the inner wall of the connecting block 203. An output gear 4032 is also provided on the end of the second rotating shaft 4031 and the output gear 4032 is meshed with the reduction gear set 2031 and drives the threaded rod 204 to rotate through the reduction gear set 2031.

[0064] Among them, the second bevel gear 403 is meshed with the first bevel gear 401. When the first bevel gear 401 is driven to rotate through the output shaft 4011, the second bevel gear 403 rotates synchronously. The end of the second rotating shaft 4031 at the axis of the second bevel gear 403 extends into the interior of the connecting block 203. The output gear 4032 at the top is meshed with the reduction gear group 2031 to drive the reduction gear group 2031 to rotate. The reduction of the reduction gear group 2031 drives the threaded rod 204 to rotate slowly and drives the lifting plate 202 to rise and fall.

[0065] Reference Figure 6 to Figure 8 A first rotating shaft 4012 is also provided at the axis center of the first bevel gear 401 and extends to the interior of the connecting shell 3011 provided on the outer wall of the driver 301. A limiting wheel 4013 is fixed to the outer wall of the first rotating shaft 4012. The limiting wheel 4013 cooperates with the adjusting member to control the direction of the first bevel gear 401.

[0066] Among them, the connecting shell 3011 is fixed to the outside of the driver 301, one end of the first rotating shaft 4012 rotates inside the connecting shell 3011, and at the same time, the limiting wheel 4013 located at the top of the first rotating shaft 4012 also rotates inside the connecting shell 3011. Since the limiting wheel 4013 and the first bevel gear 401 rotate coaxially, the rotation of the limiting wheel 4013 affects the first bevel gear 401.

[0067] A plurality of grooves are arrayed on the surface of the limiting wheel 4013, and the grooves cooperate with the adjusting member to control the rotation direction of the limiting wheel 4013. The rotation direction of the first bevel gear 401 is the same as that of the limiting wheel 4013, so as to adjust the rotation direction of the first bevel gear 401 and thus control the rise or fall of the lifting plate 202.

[0068] A sleeve 3012 is fixed to the outer wall of the connecting shell 3011, and the adjusting member is installed on the sleeve 3012. The adjusting member includes a limiting rod 402, and a slope 4021 is provided at the end of the limiting rod 402. The slope 4021 cooperates with the groove on the surface of the limiting wheel 4013 for limitation.

[0069] The sleeve 3012 is fixed to the outside of the connecting shell 3011, the limiting rod 402 is installed inside the limiting rod 402, and the inclined surface 4021 at the bottom of the limiting rod 402 is engaged with the groove on the surface of the limiting wheel 4013, and the inclined surface 4021 is in close contact with the groove. Figure 8 As shown, when the limiting wheel 4013 rotates clockwise, the groove squeezes the inclined surface 4021 to make the limiting rod 402 move upward. When the limiting wheel 4013 rotates counterclockwise, the groove contacts the straight surface of the other side of the limiting rod 402, and the limiting wheel 4013 is restricted and cannot rotate. By adjusting the direction of the inclined surface 4021 at the bottom of the limiting rod 402, the rotation direction of the first bevel gear 401 can be controlled to control the lifting and lowering activities of the lifting plate 202.

[0070] Preferably, a second elastic member 4023 is sleeved on the outer wall of the limit rod 402 and the second elastic member 4023 is located inside a movable groove 3014 opened on the inner wall of the sleeve 3012 and is used to push the limit rod 402 so that its end is engaged in the groove. A sliding column 4022 is also provided on the outer wall of the limit rod 402 and the end of the sliding column 4022 extends into the movable groove 3013 opened on the inner wall of the sleeve 3012 and slides with it.

[0071] The second elastic member 4023 is sleeved on the outside of the limiting rod 402 and is located in the movable groove 3014 on the inner wall of the sleeve 3012. The limiting rod 402 is pushed downward by the second elastic member 4023 so that the inclined surface 4021 at the bottom thereof is clamped in the groove on the surface of the limiting wheel 4013. At the same time, the sliding column 4022 on the surface of the limiting rod 402 slides in the movable groove 3013 inside the sleeve 3012. Figure 8As shown, the movable groove 3013 is a horizontal semicircular concave ring, and a limiting groove is provided at each end of the concave ring. By manually lifting and rotating the staff, the sliding column 4022 can be moved from the current limiting groove to the limiting groove at the other end, thereby realizing the rotation of the limiting rod 402. The rotation of the bottom inclined surface 4021 of the limiting rod 402 changes the rotation direction of the limiting wheel 4013, and the rotation direction of the coaxial first bevel gear 401 changes synchronously.

[0072] In summary, when in use, the driver 301 on the outside of the monkey chair body 101 is connected to the compressed gas tank through a connecting pipe. In the initial state, the elastic membrane 303 and the motion block 304 are in a horizontal position, and the column 3041 below the motion block 304 contacts the ball 3024, causing it to press the first elastic member 3023 downward, opening the air intake channel at the bottom of the driver 301, and using gas as a power source to avoid the noise and vibration generated by traditional motor drive, greatly reducing the stimulation to the easily stressed marmoset, providing a more stable and quiet environment for the experiment, while the compressed gas is transported from the gas tank to the inside of the driver 301, filling the cavity 3022 and blowing the elastic membrane 303 upward to deform, driving the motion block 304 to rise together. At this time, the ball 3024 loses the contact of the column 3041, and moves upward under the action of the first elastic member 3023, blocking the air intake channel, and the gas stops entering. Subsequently, the internal gas is discharged through the air holes 3021 on the inner plate 302, and the elastic membrane 303 recovers its deformation to drive the moving block 304 to move downward. The column 3041 pokes the ball 3024 again to open the air inlet channel, and the cycle continues, thereby realizing the cyclic up and down movement of the elastic membrane 303 and the moving block 304 in the driver 301.

[0073] When the swing rod 3042 hinged at the end of the moving block 304 moves up and down, the first bevel gear 401 is driven to rotate on the inner wall of the driver 301 through the output shaft 4011. The first bevel gear 401 is meshed with the second bevel gear 403, and the second bevel gear 403 is meshed with the reduction gear set 2031 through the output gear 4032 at the end of the second rotating shaft 4031, and finally drives the threaded rod 204 to rotate slowly, so as to realize the smooth lifting and lowering of the lifting plate 202. The first rotating shaft 4012 at the axis of the first bevel gear 401 extends into the connecting shell 3011, and the limiting rod 402 is installed in the sleeve 3012, and the bottom inclined surface 4021 is matched with the groove on the surface of the limiting wheel 4013. When the limiting wheel 4013 rotates, the interaction between the groove and the inclined surface 4021 can limit or allow its rotation. By adjusting the direction of the inclined surface 4021 of the limiting rod 402, the rotation direction of the first bevel gear 401 can be controlled, thereby controlling the rise or fall of the lifting plate 202, which is convenient for manual adjustment by the staff.
