Description

Technical Field

[0001] The utility model relates to the technical field of laboratory rat sample labeling, in particular to a rat tail labeling device. Background Art

[0002] Rats are a commonly used experimental animal. When conducting experiments on rats, it is necessary to mark certain parts of the rats. A commonly used marking location on the rat's body is the rat's tail. When marking the rat's tail, it is first necessary to select a suitable mouse container according to the size of the rat. Generally, the mouse container is a limiting cylinder with openings at both ends. Then the rat is introduced into the limiting cylinder, and the head of the limiting cylinder is blocked. Finally, the rat part located outside the limiting cylinder can be marked.

[0003] For example, in the application number CN201920304526.7, the patent name is a fixing device for laboratory mice, which includes a base, a mouse container, a screw, a push plate, a front movable baffle and a rear movable baffle. The mouse container is fixed on the base. The mouse container has front and rear end heads. A through groove is provided on the top of the mouse container. The through groove runs through the front and rear end heads. Two long strip-shaped grooves are provided on the base. The two grooves are respectively arranged at the positions of the front and rear end heads. A fixing rod is provided in each of the two grooves. The lower ends of the front movable baffle and the rear movable baffle are embedded in the grooves and connected to the fixing rod, and rotate around the fixing rod. The front movable baffle is rotated to block the front end head, and the rear movable baffle is rotated to block the rear end head. The screw cooperates with the upper end thread of the front movable baffle, the screw is fixed to the push plate, and the rotating screw controls the forward and backward movement of the push plate. In this patent, the rat is limited by the mouse container.

[0004] The applicant has found that since the size of each rat is different, when the size of the rats differs greatly, it is necessary to replace the appropriate mouse container to ensure that the labeling process can proceed smoothly. However, the model of the mouse container is fixed. There are some rats whose size is between two models of mouse containers. If such rats are placed in a small-sized mouse container, the rats may resist strongly; if such rats are placed in a large-sized mouse container, the activity space will be larger and the rats may be very unstable, making it difficult to ensure the smooth progress of the labeling. Therefore, designing a limit mechanism that can be universal for rats of different sizes is of positive significance for ensuring the smooth progress of the labeling. Utility Model Content

[0033] As attached Figure 1-Figure 6 As shown, the utility model includes: a rat tail marking device, including:

[0034] A base 1 and a mounting frame 2 arranged on the base 1;

[0035] A conical rat-carrying tube 3 for rats to pass through, the conical rat-carrying tube 3 is arranged on the mounting frame 2 through a connecting plate 4, and the inner wall of the conical rat-carrying tube 3 is provided with at least one rat tail groove 6;

[0036] A labeling mechanism for labeling the rat tail located in the rat tail groove 6;

[0037] At least one limiting mechanism, comprising:

[0038] The turning frame 10 includes a crossbar and a rotating rod disposed at the end of the crossbar, and one end of the rotating rod is provided with a rotating end rotatably connected to the connecting plate 4;

[0039] A rotating part for driving the rotating end to rotate;

[0040] A plurality of abdominal limit blocks 12 are arranged on the cross bar, and the abdominal limit blocks 12 pass through the through slots arranged on the mounting frame 2. The surface of the conical mouse-carrying tube 3 is provided with an avoidance opening 5, so that the abdominal limit blocks 12 pass through the avoidance opening 5 to enter the inside of the conical mouse-carrying tube 3 and form a limiting space between the inner wall of the conical mouse-carrying tube 3 to limit the rat.

[0041] In this embodiment, when the rat is not introduced into the conical rat-carrying tube 3, the abdomen limiting block 12 is located outside the conical rat-carrying tube 3. When the rat is introduced into the conical rat-carrying tube 3, the rotating part is started to drive the turning frame 10 to rotate so that the abdomen limiting block 12 gradually enters the conical rat-carrying tube 3. The abdomen limiting block 12 will contact the abdomen of the rat and apply a suitable clamping force to the abdomen of the rat, thereby limiting the rat in the limited space. At this time, the limbs of the rat will be in a suspended state and cannot be used for support. Therefore, the stability of the rat can be well guaranteed. Then the tail of the rat is placed in the rat tail groove 6, and the labeling mechanism can complete the labeling. The limiting mechanism can limit rats of different volumes, thereby ensuring that the labeling process can proceed smoothly.

[0042] Here, preferably, Figure 1 , Figure 2 As shown, two limiting mechanisms are provided, and the two limiting mechanisms are symmetrically arranged on both sides of the conical mouse-carrying tube 3. In this way, after the rotating part is started, the two flip frames 10 are flipped toward each other and moved closer, thereby driving the abdomen limiting blocks 12 thereon to pass through the avoidance opening 5 and gradually move closer. After the abdomen limiting blocks 12 contact the abdomen of the rat, the movement direction of the rat is limited under the synchronous clamping of the abdomen limiting blocks 12 on both sides, so that the rat will be clamped in the middle position of the conical mouse-carrying tube 3, and the rat part will be better placed in the middle rat tail groove 6, which is convenient for labeling.

[0043] In addition, the abdomen limiting block 12 is made of elastic material, so the rat can be clamped in a flexible manner, which can well protect the rat.

[0044] As an implementation method, Figure 2 As shown, the rat tail marking device also includes a plugging cover 7 detachably arranged at the outlet of the conical rat-containing tube 3 to prevent the rat from escaping from the outlet during the process of limiting the rat. In addition, the conical rat-containing tube 3 and the plugging cover 7 are preferably made of transparent material to facilitate observation of the rat.

[0045] Here we introduce a structure of a rotating part, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the rotating part includes a driving motor 8 arranged on the mounting frame 2, a gear 1 9 arranged on the output shaft of the driving motor 8 and a gear 2 11 arranged on the rotating end, and the gear 1 9 is meshed with the gear 2 11. Here, the driving motor 8 drives the gear 1 9 and the gear 2 11, thereby driving the flip frame 10 to rotate.

[0046] As an implementation method, Figure 1 , Figure 5 , Figure 6 As shown, the labeling mechanism includes:

[0047] A guide rod 13 provided on the base 1;

[0048] A lifting member 14 and a spring 15 sleeved on the guide rod 13, wherein the lifting member 14 is slidably disposed on the guide rod 13, one end of the spring 15 is fixed on the lifting member 14, and the other end of the spring 15 is fixed on the base 1;

[0049] An oil cylinder 16 and an oil seepage chamber 17 are arranged on the lifting member 14. Oil absorbing cotton is installed inside the oil seepage chamber 17. The upper end of the oil seepage chamber 17 is connected with the oil cylinder 16. The lower end of the oil seepage chamber 17 is detachably mounted with a number head 18 by means of screws.

[0050] In this embodiment, after the rat is stabilized by the limiting mechanism, the staff pushes the lifting member 14 downward so that the lower end of the oil seepage chamber 17 can dock with the rat tail groove 6 and limit the rat tail placed on the rat tail groove 6. At this time, the spring 15 is compressed. Since the lower end of the oil seepage chamber 17 and the rat tail groove 6 are multi-groove structures, the rat tail in the conical rat loading tube 3 can be limited at any swinging angle, and finally the rat tail is labeled by the labeling head 18. When different labeling operations are required for the next batch of experimental rats, it is only necessary to replace the corresponding coded labeling head 18 by loosening and tightening the screws. In the process of replacing the labeling head 18, the presence of the oil-absorbing cotton can prevent oil from overflowing from the oil seepage chamber 17.

[0051] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
