Description

Technical Field

[0001] The utility model relates to the technical field of mouse cage feeding, in particular to a feeding device for experimental mouse cages. Background Art

[0002] Mice, also known as small white mice, belong to the phylum Vertebrata, class Mammalia, order Rodentia, and family Muridae. Mice are small in size, easy to raise and manage, and easy to control. They reproduce quickly and can be weaned 3 weeks after birth. There are a large number of inbred strains, mutant strains, and closed groups with different characteristics, and a variety of internationally recognized standard strains have been formed, which are widely used in various nutritional experimental studies.

[0003] For example, Chinese patent CN221059198U discloses an automatic feeding device for Balb / C mouse feeding. By setting a positioning unit, the supporting cross plate as a carrier of the disturbance and distribution unit and the control and discharge unit can be directly placed in the positioning groove at the center of the top surface of the feeding box. By holding the turntable, the screw rod can be controlled to rotate forward and backward on the feeding box. The two support bars threadedly connected to the screw rod can be subjected to force to move relative to each other on the outside of the supporting cross plate to adjust the spacing. The two plug-in strips are driven by the support bars and can be simultaneously mobilized into the plug-in grooves on both sides of the supporting cross plate. The guide rod is set to guide the two support bars to slide and translate and provide auxiliary support for them. The feeding mechanism composed of the disturbance and distribution unit and the control and discharge unit is then locked to the feeding box as a whole. The equipment is flexible and convenient for disassembling, assembling, transporting, inspecting and maintaining the feeding mechanism as a whole.

[0004] By comparing the above existing documents, the inventor believes that there are the following defects:

[0005] In actual application, in order to maintain the hygiene of feed, the inside of the feeding device of the comparative document needs to be disinfected and cleaned frequently. However, when cleaning, the comparative document not only needs to disassemble the device, but also has to stop the machine for operation. When the scale of the cage is large, such operation is undoubtedly time-consuming and laborious, and the subsequent feeding time of the mice is easily affected when the machine is stopped for cleaning, which is not conducive to the application of multi-scale cages. In view of this, we propose the feeding device of the experimental cage to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1 and Figure 2 A feeding device for experimental mouse cages includes a shell 1, a base 2 and a top cover 15. A first feeding box 3 and a second feeding box 4 are arranged inside the shell 1, and a connecting component for connecting the base 2 is arranged on the surface of the shell 1.

[0026] See also Figure 3 and Figure 4 The connecting assembly includes a first fixed block 6, a second fixed block 7, a third fixed block 8, a sleeve 9, a rotating rod 11 and a limit block 12. The first fixed block 6 is fixedly installed on the surface of the base 2, the second fixed block 7 and the third fixed block 8 are fixedly installed on the surface of the shell 1, the sleeve 9 is fixedly installed on the top of the first fixed block 6, one end of the second fixed block 7 extends to the inside of the sleeve 9, the second fixed block 7 is located inside the sleeve 9 and is fixedly installed with a square block 22, and a counterweight block 10 is also fixedly installed on the inner wall of the sleeve 9, the rotating rod 11 is rotatably installed on the top of the counterweight block 10 and the other end passes through the square block 22 and the third fixed block 8, the limit block 12 is fixedly installed on the surface of the rotating rod 11, and the surface of the third fixed block 8 is also provided with a groove 13 adapted to the limit block 12.

[0027] Among them, by setting the first feeding box 3 and the second feeding box 4, when the first feeding box 3 is cleaned, the second feeding box 4 can replace the first feeding box 3 to continue the feeding work, thereby making it difficult for the device to affect the subsequent feeding time due to the cleaning of the feeding device. At the same time, when taking out the first feeding box 3, it is only necessary to rotate the lower rotating rod 11 so that the limit block 12 passes through the slot 13, and the base 2 will automatically separate from the shell 1, thereby directly taking out the first feeding box 3. The operation is simple and convenient, and the production cost is low. It is not only suitable for a single mouse cage, but also suitable for mouse cages of multiple sizes, thereby improving the practicality of the device.

[0028] In addition, the groove inside the sleeve 9 is square, the square block 22 is slidably connected to the inner wall of the sleeve 9, and an opening is also provided on one side of the sleeve 9, and the second fixing block 7 is slidably connected to the inner wall of the opening.

[0029] It is worth noting that the second fixing block 7 is used to limit the sleeve 9 so that the base 2 is not likely to automatically deflect when the base 2 is separated from the shell 1 .

[0030] See also Figure 3 In this embodiment, a slot is provided on the lower surface of the shell 1, and an insert block 14 extending into the slot is fixedly mounted on the upper surface of the base 2. A feed inlet and a discharge port are provided on the upper and lower surfaces of the first feeding box 3 and the second feeding box 4, respectively, and a sealing plug 5 is clamped inside the discharge port and the feed inlet.

[0031] The plug block 14 and the slot are provided to improve the tightness of the connection between the housing 1 and the base 2.

[0032] In addition, the sealing plug 5 is provided to improve the sealing performance of the first feeding box 3 and the second feeding box 4, so that it is not easy for external air to enter the first feeding box 3 and the second feeding box 4 to cause feed deterioration.

[0033] It is worth noting that the outer walls of the first feeding box 3 and the second feeding box 4 are both in contact with the inner wall of the shell 1 , and the discharge port of the first feeding box 3 extends to the outside of the base 2 .

[0034] See also Figure 5 In this embodiment, the top cover 15 is rotatably mounted on the top of the housing 1 , and two L-shaped fixing rods 16 are fixedly mounted on the surface of the housing 1 .

[0035] A positioning assembly is also provided at the end of the fixing rod 16 away from the housing 1, and the positioning assembly includes a mounting block 17 fixedly mounted on the end of the fixing rod 16 away from the housing 1, a screw rod 18 is threadedly mounted on one side of the mounting block 17, a first positioning block 20 is fixedly mounted on the inner wall of the other side of the mounting block 17, a second positioning block 19 is rotatably mounted on the end of the screw rod 18 close to the first positioning block 20, and a slider 21 extending into the interior of the mounting block 17 is also fixedly mounted on one side of the second positioning block 19.

[0036] The inner wall of the mounting block 17 is provided with a slide groove, the slider 21 is slidably connected to the inner wall of the slide groove, and anti-slip pads are installed on the opposite sides of the first positioning block 20 and the second positioning block 19.

[0037] In addition, by rotating the screw rod 18, the second positioning block 19 is limited by the slider 21 and cannot rotate, so that the second positioning block 19 will move when the screw rod 18 rotates. The mutual cooperation of the first positioning block 20 and the second positioning block 19 facilitates the fixing of the device to the squirrel cage, and the provision of the anti-slip pad makes the device more stable after fixing, thereby improving the efficiency of the overall disassembly and assembly of the device.

[0038] It is worth noting that in the present application, the first positioning block 20 and the second positioning block 19 are arc-shaped plates, that is, the side walls of the squirrel cage are defaulted to be composed of round bars, and the shapes of the first positioning block 20 and the second positioning block 19 can be adjusted according to the shape of the squirrel cage.

[0039] When the present embodiment is in use, the sealing plug 5 at the bottom of the first feeding box 3 is removed so that the feed inside the first feeding box 3 can be put into the mouse cage. When the first feeding box 3 needs to be taken out for disinfection and cleaning, the rotating rod 11 is rotated to rotate the limit block 12. When the limit block 12 is aligned with the slot 13, the sleeve 9 will move downward under the gravity of the counterweight 10, thereby driving the rotating rod 11 to move downward. When the sleeve 9 moves downward, the base 2 moves downward, thereby separating the shell 1 from the base 2. When the base 2 moves downward, the first feeding box 3 will also move downward. The staff only needs to take out the first feeding box 3 to disinfect and clean it. The feeding box 3 can then reset the base 2. After the base 2 is reset, the rotating rod 11 will also reset, so that the limit block 12 can be moved to the top of the third fixed block 8 through the slot 13. At this time, the rotating rod 11 can be rotated to make the limit block 12 and the third fixed block 8 engage with each other, thereby completing the connection of the base 2. After the first feeding box 3 is cleaned, the top cover 15 is opened and placed into the shell 1. As a result, the device is not easily affected by the subsequent feeding time when the feeding device is cleaned, and the production cost is low. It is not only suitable for a single cage, but also suitable for cages of multiple sizes, which greatly improves the practicality of the device.

[0040] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.

[0041] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
