DETAILED DESCRIPTION

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] See also Figure 1-4 As shown, in this embodiment, an experimental animal transfer cage is provided, comprising: a mobile frame 1, a bottom plate 2 provided on the mobile frame 1, a tray 3 provided on the bottom plate 2, a hollow support plate 4 provided on the mobile frame 1, hollow fixing plates 5 provided at opposite ends of the hollow support plate 4, two hollow extrusion plates 6 provided between the two hollow fixing plates 5, and a cover plate 7 slidably fitted on the upper sides of the two hollow fixing plates 5, wherein the tray 3 is located below the hollow support plate 4;

[0031] Two slide grooves 8 are provided on one side of the hollow fixed plate 5, and two sliders 9 are provided on both sides of the hollow extrusion plate 6. The sliders 9 slide in the slide grooves 8, and a first fixing piece that cooperates with the hollow extrusion plate 6 is provided on one side of the hollow fixed plate 5.

[0032] One aspect of the application of this embodiment is: when it is necessary to operate or capture experimental animals;

[0033] When dealing with relatively gentle animals and / or animals with low resistance, the cover plate 7 can be directly slid to expose the top of the transfer cage, so that the experimenter can easily grab or operate the experimental animal from the top of the transfer cage.

[0034] When facing more aggressive animals and / or animals with greater resistance, the first fixing member releases the restriction on the hollow extrusion plate 6, and pushes one of the hollow extrusion plates 6 or both hollow extrusion plates 6 at the same time, so that the distance between the two hollow extrusion plates 6 gradually decreases. In this way, the experimental animal is squeezed and fixed by the two hollow extrusion plates 6, achieving the effect of preliminary control of the experimental animal, which makes it easier for the experimenter to grab or operate the experimental animal. It should be noted that all electrical equipment involved in this application can be powered by batteries or external power supply.

[0035] By setting the hollow fixing plate 5 and the hollow squeezing plate 6, the breathing stability and air permeability of the experimental animals in the transfer cage can be improved, and the set cover plate 7 can make the experimental animals enter and exit the top of the transfer cage, which is convenient for the experimenters to operate and capture. The set hollow squeezing plate 6 can slide within the two hollow fixing plates 5, thereby reducing the gap between the two hollow squeezing plates 6, and then squeezing and controlling the experimental animals, reducing the resistance of the experimental animals that makes it inconvenient for the experimenters to capture and operate, and further improving the operation and capture of the experimenters.

[0036] Specifically, the multiple hollow structures of the present invention can ensure respiratory stability for experimental animals within the cage, facilitate ventilation and air distribution, and enhance the vitality of the experimental animals. The hollow structures can be shaped like holes, flowers, hearts, fruits, etc. By designing different hollow shapes, the experimental animal transfer cage can be more personalized.

[0037] In this embodiment, a chain is mounted on one side of the hollow fixing plate 5, with a collar attached to one end. The chain and collar effectively control the range of movement of experimental animals, facilitating their management. Furthermore, the collar can be equipped with a smart lock, reducing the risk of animal resistance when manually untying or fastening the collar. The smart lock is electrically connected to a controller that can be set to a non-release mode, further improving the safety of experimental personnel and reducing the likelihood of stress, resistance, and escape in experimental animals during manual operation.

[0038] Specifically, the first end of the chain is fixed to one side of the hollow fixing plate 5, and the fixing method can be knotted or locked. The smart lock selectively controls the collar to be closed or opened based on the control command issued by the controller. The source of the control command can be the controller or the control unit inside the smart lock. As for the controller, a non-contact controller based on infrared, Bluetooth, WiFi, NFC or lidar can be set, so that the experimenter can eliminate the tedious and dangerous work scene of manually connecting and disconnecting the experimental animal and the collar, and can realize the opening or closing of the collar in a non-contact scenario.

[0039] Specifically, the length of the chain can be adjusted. For example, an extended chain can be set to achieve the function of lengthening the chain to meet the needs of transferring specific experimental animals. An elastic chain can also be set to protect the experimental animals when they struggle. An electronic chain can also be set to improve the versatility and reusability of the chain by controlling the function of the electronic chain.

[0040] Specifically, a hook is provided inside the hollow fixing plate 5, which is used to hang at least a collar. This embodiment is applicable when the experimental animal transfer cage is empty, and the collar can be hung on the hook. When the experimenter uses the experimental animal transfer cage again, the collar can be easily retrieved without falling into the gaps in the grid structure due to its bulk, thereby facilitating the management and control of the experimental animals.

[0041] Specifically, the smart lock can also control other body parts of the experimental animals, such as hands, waist and / or legs, and can also control the closing of the collar openings of multiple animals in the cage or other cages to improve the work efficiency of the experimenters.

[0042] like Figure 1-2 As shown, a placement groove 10 is provided on the bottom plate 2 of this embodiment, and the tray 3 is located in the placement groove 10. The tray can be used to collect the excrement of experimental animals or disinfection and cleaning waste liquid, so that the experimenter can clean it up in time.

[0043] like Figure 1-3 As shown, two connecting plates 11 are installed on one side of the hollow extrusion plate 6 of this embodiment, and a push rod 12 is provided between the two connecting plates 11. The push rod 12 is provided so that the experimenter can easily hold the push rod 12 to drive the hollow extrusion plate 6 to slide between the two hollow fixing plates 5.

[0044] like Figure 3 As shown, two opposing "7"-shaped limiting frames 15 are provided at the upper edge of the hollow fixing plate 5 of this embodiment. The cover plate 7 is slidably fitted between the two "7"-shaped limiting frames 15. A second fixing member that cooperates with the hollow fixing plate 5 is installed on one side of the cover plate 7. The "7"-shaped limiting frames 15 can limit the position of the cover plate 7, and the cover plate 7 can be used to block and seal the top of the transfer cage. The second fixing member can limit and secure the sealed cover plate 7, thereby fixing the position of the cover plate 7 and reducing the possibility of the cover plate 7 being offset due to transfer vibration.

[0045] like Figure 1-2As shown, the lower side of the mobile frame 1 of this embodiment is provided with a plurality of moving wheels 16, and the upper side of the mobile frame 1 is equipped with a push handle 17, and the push handle 17 is provided with an anti-slip cover 18. The anti-slip cover 18 can be made of rubber material, and rubber particles are provided on the rubber material to increase friction and contact comfort, thereby improving the work efficiency and work experience of the experimenter. The push handle 17 is provided to facilitate the experimenter to push, and the plurality of moving wheels 16 can move the transfer cage in any direction under the action of the driving force. The moving wheels 16 can be universal wheels in the prior art.

[0046] Specifically, protective pads are provided on the opposite sides of the two hollow extrusion plates 6 , and the protective pads are used to reduce the damage caused to the experimental animals when they are squeezed.

[0047] The specific first fixing member and the second fixing member can be pins or other structures in the prior art, and will not be described in detail here.

[0048] In order to reduce the need for experimenters to continuously apply pressure when squeezing experimental animals, the following three embodiments are proposed;

[0049] Example 1, as Figure 3-4 As shown, the end of the slider 9 of this embodiment is configured as a hemispherical structure, and the slider 9 is elastically fitted to one side of the hollow extrusion plate 6. A plurality of hemispherical slots that cooperate with the hemispherical structure are provided in the chute 8. By configuring the end of the slider 9 as a hemispherical structure, the hemispherical structure can cooperate with the arcuate surface of the hemispherical slot, allowing the slider 9 to be retracted into the hollow extrusion plate 6. When the slider 9 is directly opposite the hemispherical slot, it can be snapped into the hemispherical slot, limiting the position of the hollow extrusion plate 6 and reducing the trouble of the experimenter having to continuously apply pressure to the hollow extrusion plate 6.

[0050] In the second embodiment, the end of the slider 9 of this embodiment is set as a right-angled triangle structure, and the slider 9 is elastically matched with one side of the hollow extrusion plate 6. A plurality of right-angled triangle slots that match the right-angled triangle structure are opened in the slide 8. By setting the end of the slider 9 as a right-angled triangle structure, the right-angled triangle structure can be matched with the inclined surface of the right-angled triangle slot to retract the slider 9 into the hollow extrusion plate 6. When the slider 9 is facing the right-angled triangle slot, it can be stuck in the hemispherical slot to limit the position of the hollow extrusion plate 6. The right-angled triangle structure is matched with the flat side of the right-angled triangle slot, which can facilitate the two hollow extrusion plates 6 to match the inclined side of the right-angled triangle slot through the right-angled triangle structure. When the two hollow extrusion plates 6 are subjected to pressure, the distance between the two hollow extrusion plates 6 can be reduced. The right-angled triangle structure is matched with the flat side of the right-angled triangle slot to prevent the two hollow extrusion plates 6 from moving away from each other, thereby reducing the trouble of the experimenter needing to continuously apply pressure to the hollow extrusion plate 6.

[0051] Example 3, as Figure 3-4 As shown, the slider 9 of this embodiment is a cylindrical rod structure, and a groove 13 is opened on one side of the hollow extrusion plate 6. A control rod 14 is slidably fitted in the groove 13, and one end of the control rod 14 is fixedly connected to the slider 9. The control rod 14 is provided to facilitate the experimenter to control the slider 9 to retract into the hollow extrusion plate 6 by controlling the control rod 14. On the one hand, it is convenient for the experimenter to reset the hollow extrusion plate 6 in Example 2. On the other hand, it is convenient for the experimenter to retract the two sliders 9 located on the side close to the cover plate 7 into the hollow extrusion plate 6, thereby rotating the hollow extrusion plate 6 and making the transfer cage have the effect of opening from the side.

[0052] The present invention is not limited to the above-described embodiments. Any structural changes made under the guidance of the present invention should be understood by anyone. Any technical solution that is the same or similar to the present invention falls within the scope of protection of the present invention. The technology, shape, and structure not described in detail in the present invention are all known technologies.
