Description

Technical Field

[0001] This utility model relates to the technical field of laboratory animal feeding equipment, and specifically discloses a replaceable head-type quantitative feeding spoon for laboratory animals. Background Technology

[0002] In the husbandry and management of laboratory animals, precise quantitative feeding is a crucial step in achieving standardization and ensuring the reliability of experimental results. However, current laboratory animal feeding tools have the following shortcomings, making them difficult to meet the needs of standardized husbandry: Existing feeding scoops are mostly integrated structures with only one capacity and shape, which cannot adapt to the different feeding needs of different types of laboratory animals (such as small mice and rats, medium-sized rabbits, and large dogs and pigs). Feeders need to frequently change feeding tools of different sizes, which is cumbersome and inefficient. It is also easy to cause errors in feeding amount estimation due to tool switching, resulting in feed waste or insufficient feeding. The existing feeding scoops rely on the experience of the feed handlers to estimate the weight of the feed (or indirectly estimate it by visually estimating the volume). When feeding repeatedly, it is impossible to guarantee that the amount of feed is consistent each time. Long-term use can easily lead to significant differences in the weight and physical condition of individual experimental animals, undermine the standardization of experimental animal husbandry, and thus affect the authenticity and accuracy of subsequent animal experimental results, increasing experimental errors. Summary of the Invention

[0003] This invention proposes a replaceable-head feeding spoon for laboratory animals. By combining a replaceable spoon head with an adjustable positioning plate, it achieves multiple uses of a single spoon, precise quantitative feeding, and efficient operation, effectively improving the standardization level and management efficiency of laboratory animal husbandry.

[0004] This invention is achieved by providing a replaceable head-type quantitative feeding spoon for laboratory animals, comprising a handle and a head, wherein the head is detachably connected to the handle; the head is provided with an adjustable positioning plate that can slide along the inner wall of the head, and the adjustable positioning plate is used to control the maximum volume of feeding per feeding by adjusting its position within the head, thereby achieving quantitative feeding.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0020] Please see Figure 1-3 A replaceable-head experimental animal feeding spoon includes a spoon handle 1 and a spoon head 2, the spoon head 2 being detachably connected to the spoon handle 1; the spoon head 2 is provided with an adjustment positioning plate 3 that can slide along the inner wall of the spoon head 2, the adjustment positioning plate 3 is used to control the maximum volume of a single feeding by adjusting its position in the spoon head 2, thereby achieving quantitative feeding.

[0021] In this embodiment: When using this measuring spoon, firstly, select a spoon head 2 of appropriate capacity and shape according to the species and amount of food to be fed to the experimental animals, and securely connect it to the spoon handle 1 with a snap or thread; then, rotate the adjusting rod 6, which drives the sleeve 5 through the threaded pair, causing the partition 4 fixed thereto to slide precisely along the inner wall of the spoon head 2. The user refers to the capacity scale markings 9 on the inner side wall of the spoon head 2 to adjust the partition 4 to the target capacity position. At this time, the self-locking characteristic of the adjusting rod 6 thread can fix the position of the partition 4, thereby accurately limiting the effective volume of feed contained in the spoon head 2; when scooping feed, the partition 4 acts as a baffle to ensure that the volume of feed loaded each time is constant, realizing quantitative feeding, while the leakage hole 10 at the bottom of the spoon head 2 can screen out small residues and powders in the feed; finally, put the feed in the spoon into the feeding trough to complete a precise feeding.

[0022] As a technical optimization of this utility model, the adjusting positioning plate 3 includes a partition plate 4, a sleeve 5 fixedly connected to the partition plate 4, and an adjusting rod 6 threadedly connected to the sleeve 5; the adjusting rod 6 is rotatably supported on the side wall of the spoon head 2 by a bearing 7, and its axial movement is restricted; a rotating handle 8 is provided on the outer wall of the adjusting rod 6 near the bearing 7, and by rotating the rotating handle 8, the sleeve 5 moves axially along the adjusting rod 6, thereby driving the partition plate 4 fixedly connected to the sleeve 5 to move linearly along the inner wall of the spoon head 2.

[0023] In this embodiment: by rotating the handle 8 on the outer wall of the rotating adjustment rod 6, the sleeve 5 and the partition 4 are driven to move, so as to achieve precise and stable adjustment of the position of the positioning plate and avoid the position deviation problem of manual pushing; the design of the rotating handle 8 reduces the difficulty of operation and improves the convenience and accuracy of quantitative adjustment; and the height of the partition 4 is higher than the height of the spoon head 2, so when the quantitative spoon is inserted into the feed, the feed is prevented from entering the other side of the partition 4.

[0024] As a technical optimization of this utility model, a capacity scale mark 9 is provided on the top of one side wall of the spoon head 2.

[0025] In this embodiment: the capacity scale markings 9 on the inner side wall of the spoon head 2 allow the feeder to read the feeding volume intuitively. Combined with the adjustment positioning plate 3, "visual quantitative" is achieved, solving the error problem of "estimation based on experience" in existing tools, and further ensuring the accuracy of single and repeated feeding.

[0026] As a technical optimization of this utility model, the spoon head 2 has various shapes, including cylindrical or flat, to adapt to different feeding troughs or feed types.

[0027] In this embodiment, the spoon head 2 has two specific shapes: a cylindrical shape to fit small feeding troughs / holes, preventing feed from spilling when adding feed; and a flat shape to fit scenarios with large feeding volumes, and to facilitate shoveling and cleaning, covering the needs of different feeding scenarios and improving the versatility of the tool.

[0028] As a technical optimization of this utility model, the spoon head 2 has a variety of different capacity specifications, which are suitable for experimental animals of different sizes.

[0029] In this embodiment, three capacity specifications (such as 50g, 200g, and 1100g) and their corresponding applicable animals can accurately match the differentiated feeding amounts of small (mice, mice, rats), medium (rabbits / guinea pigs), and large (dogs / pigs) laboratory animals, eliminating the need for frequent estimations or tool changes, thus improving feeding efficiency and standardization.

[0030] As a technical optimization of this utility model, the bottom of the spoon head 2 is provided with a leakage hole 10. The size of the leakage hole 10 is designed according to the size of the feed particles and is used to filter feed residue.

[0031] In this embodiment: the waste leakage hole 10 and its diameter can filter residue according to the size of feed particles, avoid spoiled residue from being mixed into the feed and affecting animal health, reduce feed waste, and ensure the cleanliness of the fed feed.

[0032] As a technical optimization of this utility model, the end of the spoon handle 1 near the spoon head 2 is provided with a connecting part 11, and the spoon head 2 is provided with a mating part 12 that matches the connecting part 11. The connecting part 11 and the mating part 12 are connected by a snap-fit ​​connection or a threaded connection.

[0033] In this embodiment, the detachable connection structure between the spoon handle 1 and the spoon head 2 enables quick and stable assembly and disassembly of the spoon head 2, facilitates the operation when replacing spoon heads 2 of different specifications, avoids feeding errors caused by loose connections, and further improves the flexibility and reliability of the tool.

[0034] Working principle and usage process of this utility model: Based on the size of the experimental animals to be fed (e.g., 50g capacity for mice and rats, 200g capacity for rabbits, and 1100g capacity for dogs) and the type of feeding trough (cylindrical for small feeding troughs, flat for large-volume feeding), select the corresponding size of spoon head 2; securely install the spoon head 2 onto the spoon handle 1 using the snap-fit ​​or threaded structure between the connecting part 11 of the spoon handle 1 and the mating part 12 of the spoon head 2; holding the spoon handle 1, rotate the rotating handle 8 of the adjusting positioning plate 3, causing the adjusting rod 6 to rotate; because the axial movement of the adjusting rod 6 is restricted, its threaded engagement with the sleeve 5 drives the sleeve 5 and the partition 4 to slide along the inner wall of the spoon head 2; refer to the capacity of the inner wall of the spoon head 2. Scale mark 9: Adjust the partition 4 to the scale line corresponding to the target feeding volume to complete the quantitative setting; insert the adjusted quantitative spoon into the feed, and the feed enters the fixed volume space formed by the partition 4 and the bottom of the spoon head 2. Excess feed can be scraped off along the edge of the spoon head 2; move the quantitative spoon to the experimental animal feeding trough and pour the feed to complete the feeding. During the feeding process, the leakage hole 10 at the bottom of the spoon head 2 simultaneously filters the feed residue; if it is necessary to feed the same volume of feed repeatedly, there is no need to adjust the positioning plate 3 again; if it is necessary to change the feeding animal or adjust the feeding amount, first separate the spoon handle 1 from the current spoon head 2, select and adjust the new specification spoon head 2, and then feed.

Therefore, they should not be construed as limitations on this utility model.

[0036] However, the above are merely specific embodiments of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
