[0038] Furthermore, by making the box body 100, neck locking plate 200, trunk fixing plate 300, trunk locking plate 400, front baffle plate 500 and support plate 600 all non-metallic parts, the electromagnetic compatible primate fixing chair 1 will not affect the electromagnetic environment, and the electromagnetic compatible primate fixing chair 1 can be set in an electromagnetic exposure environment, thereby avoiding the interference of the electromagnetic compatible primate fixing chair 1 on the electromagnetic exposure environment, so that the electromagnetic compatible primate fixing chair 1 can be used for primate experiments in electromagnetic exposure environments, and the electromagnetic compatible primate fixing chair 1 has good electromagnetic compatibility, thereby improving the applicability of the electromagnetic compatible primate fixing chair 1.

[0039] Therefore, the electromagnetic compatible primate fixation chair 1 according to the embodiment of the present invention has the advantages of strong applicability, convenient operation, and a large range of animal activities.

[0040] The following describes an electromagnetic compatible primate fixing chair 1 according to a specific embodiment of the present invention with reference to the accompanying drawings.

[0041] In some specific embodiments of the present invention, Figure 1-Figure 6 As shown, the electromagnetic compatible primate fixing chair 1 according to the embodiment of the present invention includes a box body 100 , a neck locking plate 200 , a trunk fixing plate 300 , a trunk locking plate 400 , a front baffle plate 500 and a support plate 600 .

[0042] Advantageously, if Figure 1-Figure 6 As shown, the trunk fixing plate 300 and the support plate 600 are movably arranged in the box body 100. This makes it easy to adjust the height of the trunk fixing plate 300 and the support plate 600, so that the electromagnetic compatible primate fixing chair 1 can be suitable for primates of different sizes.

In this way, the height adjustment of the position of the trunk fixing plate 300 can be achieved by selecting the position of the trunk adjustment fastener, and the height adjustment of the position of the support plate 600 can be achieved by selecting the position of the support adjustment fastener. In addition, the plug-in connection between the trunk connecting pin 320 and the trunk adjustment plate 710 and the plug-in connection between the support connecting pin 620 and the support adjustment plate 720 can avoid the use of metal connectors, thereby avoiding the influence of metal connectors on the electromagnetic exposure environment.

[0044] Specifically, the trunk adjustment fastener, the support adjustment fastener, the trunk adjustment plate 710 and the support adjustment plate 720 are non-metallic parts, so that the trunk adjustment fastener, the support adjustment fastener, the trunk adjustment plate 710 and the support adjustment plate 720 can be prevented from affecting the electromagnetic exposure environment.

[0045] More specifically, Figure 1-Figure 6As shown, the front parts of the two side panels 130 are provided with baffle guide rails 510, the left and right edges of the front baffle 500 are respectively slidably matched in the two baffle guide rails 510, the left and right side walls of the neck fixing groove 111 are provided with neck locking plate guide grooves 210, the left and right edges of the neck locking plate 200 are respectively slidably matched in the neck locking plate guide grooves 210, the left and right side walls of the trunk fixing groove 310 are provided with trunk locking plate guide grooves 410, the left and right edges of the trunk locking plate 400 are respectively slidably matched in the trunk locking plate guide grooves 410. Specifically, the front baffle 500 can be slidably matched with the baffle guide rails 510 up and down. In this way, the baffle guide rails 510 can be used to guide the sliding of the front baffle 500, the trunk locking plate guide grooves 410 can be used to guide the sliding of the trunk locking plate 400, and the neck locking plate guide grooves 210 can be used to guide the sliding of the neck locking plate 200. In addition, the sliding movement of the torso locking plate 400 and the neck locking plate 200 can be adapted to primates of different body sizes.

[0046] Figure 1-Figure 6 The electromagnetic compatible primate fixed chair 1 according to some examples of the present invention is shown. Figure 1-Figure 6 As shown, a downwardly concave positioning groove 610 is formed on the support plate 600, and a defecation opening 611 is provided on the bottom wall of the positioning groove 610. In this way, the primate can sit in the positioning groove 610, and the positioning groove 610 is used to position the lower part of the primate's trunk, and the defecation opening 611 can facilitate the primate to defecate.

In this way, the collection tray 800 can be used to collect feces discharged from the defecation port 611, and the feces can be centrally cleaned by removing the collection tray 800. In addition, the collection tray 800 is a non-metallic part to prevent the collection tray 800 from interfering with the electromagnetic exposure environment.

[0048] Specifically, a handle 810 is provided on the collection tray 800. This makes it easy to push and pull the collection tray 800, and to disassemble and assemble the collection tray 800.

[0049] More advantageously, if Figure 6 As shown, the top plate 110 of the box body 100 extends upwardly from front to back, which can make the fixed primate more comfortable and have a wider field of vision.

[0050] Optionally, the box 100 is a transparent member, so that the primate in the box 100 can be easily observed through the box 100 .

[0051] Specifically, the top plate 110, the rear plate 120, and the two side plates 130 are connected by a mortise and tenon structure or non-metallic screws. Specifically, the side plates 130 and the rear plate 120 can be connected by non-metallic screws, and the top plate 110 can be provided with a plurality of spaced tenons 112, and the side plates 130 and the rear plate 120 can be provided with a plurality of spaced tenons 133, and the tenons 112 fit into the tenons 133. In this way, the use of metal connectors can be avoided, and the metal connectors can be prevented from interfering with the electromagnetic environment.

[0052] More specifically, Figure 2 As shown, an operation port 123 is provided on the rear panel 120. This not only reduces the weight of the electromagnetic compatible primate fixing chair 1, but also makes it easier for the operator to operate the box 100 through the operation port 123. For example, when fixing the primate, the operator cooperates with the inlet and outlet 101 through the operation port 123.

[0053] Furthermore, a plurality of connecting rods 900 may be provided at the lower part of the two side plates 130, and the connecting rods 900 are non-metal parts, so that the structure of the box body 100 can be more stable.

[0054] The primate fixed chair in this design is made entirely of non-metallic materials with good electromagnetic compatibility and can be used in microwave environments. The mortise and tenon structure design is adopted as much as possible to reduce the use of connectors. Considering the applicability of the fixed chair, a structure suitable for animals of different sizes is designed. Considering the needs of animals to complete different tasks, a large range of activities and a wide field of view are designed.
