[0024] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiment is only one embodiment of the present invention, not all embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Unless otherwise defined, technical or scientific terms used in the present invention shall have the same meaning as commonly understood by one of ordinary skill in the art to which the present invention belongs.

[0026] This embodiment provides a non-human primate experimental restraint device.

[0027] Reference Figure 1 A non-human primate experimental restraint device includes a base 1, a backrest assembly 2, and a head assembly 3, arranged in order from bottom to top. The base 1 is used to support the backrest assembly 2, which is used to fix the primate's waist and legs, and the head assembly 3 is used to fix the head.

[0028] Reference Figure 1 、 Figure 2 The base 1 includes a base frame 11 and a pair of support columns 12. The base frame 11 is provided with a pulley 111 to facilitate moving the animal restraint device. The pair of support columns 12 are vertically arranged and distributed on both sides of the base frame 11.

[0029] The backrest assembly 2 includes a backrest panel 21 and a seat panel 22. The backrest panel 21 is vertically positioned between a pair of support columns 12. The backrest panel 21 is hinged to the two support columns 12 on either side via damping shafts, allowing for adjustment of the backrest assembly 2's rotation angle, and thus, the primate's sitting posture. Horizontally positioned on either side of the backrest panel 21 are armrest panels 211, each with grooves 2111 along its length for the primate's arms to fit into.

[0030] The seat plate 22 is horizontally arranged below the back plate 21 , and a pair of leg support plates 221 are provided at one end of the seat plate 22 away from the back plate 21 . The pair of leg support plates 221 are distributed on both sides of the seat plate 22 and are used to support the legs of the primate.

[0031] The backrest 21, arm support plate 211, and leg support plate 221 are respectively provided with a first lashing assembly, a second lashing assembly, and a third lashing assembly. The first lashing assembly, the second lashing assembly, and the third lashing assembly are respectively used to lash the primate's waist, arms, and legs, thereby securing the primate to the backrest assembly 2. The first lashing assembly, the second lashing assembly, and the third lashing assembly can be simple lashing structures such as ropes or nylon straps with Velcro.

[0032] Reference Figure 2 To adapt the backrest assembly 2 to the needs of primates of different heights, a retractable support rod 4 is vertically installed on the back of the backrest 21. The retractable support rod 4 includes a main support tube 41, an upper retractable rod 42, and a lower retractable rod 43. The upper end of the upper retractable rod 42 is connected to the head assembly 3, and the lower end of the lower retractable rod 43 is connected to the seat plate 22. The lower end of the upper retractable rod 42 and the upper end of the lower retractable rod 43 are respectively inserted through the two ends of the main support tube 41 and vertically slidably connected thereto.

[0033] A first locking mechanism 411 is provided at each end of the main support tube 41. The two first locking mechanisms 411 are used to control the length of the upper telescopic rod 42 and the lower telescopic rod 43, respectively, within the main support tube 41. The first locking mechanism 411 includes a spring latch 4111. The upper telescopic rod 42 and the lower telescopic rod 43 are evenly distributed along their lengths with a plurality of locking holes 44. The locking holes 44 are used to receive the spring latches 4111. The spring latches 4111 cooperate with the locking holes 44 to adjust the length of the telescopic support rod 4.

[0034] In actual application, the spring latch 4111 can also be replaced by a locking device such as an impact lock pin or a bolt.

[0035] Reference Figure 1 、 Figure 2 The seat plate 22 is evenly distributed with a plurality of strip-shaped holes 222, and a retractable waste tray 5 is provided below the seat plate 22, so that feces can fall through the strip-shaped holes 222 and onto the waste tray 5. At the same time, a strike-type locking pin is provided between the waste tray 5 and the seat plate 22. The strike-type locking pin is used to lock the connection between the waste tray 5 and the seat plate 22 to ensure the stability of the connection between the waste tray 5 and the seat plate 22 during the angle adjustment of the backrest assembly 2.

[0036] Reference Figure 1 、 Figure 3 The head assembly 3 includes a head plate 31 and a telescopic assembly 32. The head plate 31 is horizontally arranged above the back plate 21. A head hole 311 for the primate's head to pass through is provided above the head plate 31, and the telescopic assembly 32 is used to adjust the size of the head hole 311.

[0037] The telescopic assembly 32 includes a horizontally arranged telescopic plate 321 and a neck plate 322 arranged on the telescopic plate 321. One end of the head hole 311 passes through the head plate 31, and the neck plate 322 is arranged in an arc shape at one end relative to the head hole 311. Slide tubes are arranged on both sides of the bottom of the head plate 31 along its length direction, and sliding rods are arranged on both sides of the bottom of the telescopic plate 321 along its length direction, which are passed through the slide tubes and horizontally slidably connected to the slide tubes, so that the size of the head hole 311 can be adjusted by driving the neck plate 322 to slide through the telescopic plate 321, thereby adapting to the fixation needs of the heads of animals of different sizes.

[0038] A headrest 312 is also provided on the side of the headboard 31 away from the neckboard 322. This supports the primate's head and may include a flexible cushion to ensure comfort while the primate is secured. To facilitate the installation of components such as the head cover, one side of the headrest 312 is hinged to the headboard 31. During head restraint, the headrest 312 is positioned above the headboard 31. When installing components such as the head cover, the headrest 312 can be flipped to the outside of the headboard 31.

[0039] A second locking mechanism for locking the position of the slide rod is provided on the slide cylinder, and a third locking mechanism for locking the position of the headrest 312 is provided on the head plate 31. The second locking mechanism and the third locking mechanism are similar to the first locking mechanism 411, and locking devices such as spring latch 4111, impact lock pin or bolt can be used.

[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
