Description

Technical Field

[0001] This utility model relates to the field of animal experimental equipment technology, and in particular to a mouse marker. Background Technology

[0002] In animal experiments, marking mice is used to distinguish individuals, identify groups, and track the experimental process. The main marking methods in the existing technology are staining, ear tagging, and toe clipping. Among them, ear tagging is fixed to the mouse's ear by inserting the male and female ends of the ear tag together. However, because the contact area between the ear tag and the animal's ear is small and the fixation method is simple, in actual use, the ear tag may be pulled or opened again during the mouse's activity and play, which not only causes secondary injury to the animal, but also makes the ear tag easy to break and fall off. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a mouse marker.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A mouse tagger includes a C-shaped buckle with male and female ends, which are interlocked. A protruding wedge-shaped block is provided on one side of the male end, and a pair of protrusions are provided on the upper part away from the wedge-shaped block.

[0006] The female head has a snap-fit ​​groove on one side to engage with the protrusion, and a wedge groove is provided below it away from the snap-fit ​​groove to engage with the wedge block.

[0007] The top of the inner wall of the C-shaped buckle is provided with a pair of positioning pins, and the bottom of the inner wall of the C-shaped buckle is provided with a snap-fit ​​pin groove corresponding to the positioning pins. The snap-fit ​​pin groove and the positioning pins are a snap-fit ​​mechanism for each other.

[0008] Furthermore, in a preferred configuration, silicone pads are provided on both the upper and lower ends of the inner wall of the C-shaped buckle, and when the male and female heads of the C-shaped buckle are connected to each other, the silicone pads are pressed and contacted with each other.

[0009] Furthermore, in a preferred configuration, a marking plate is provided on the upper part of the C-shaped buckle.

[0010] Furthermore, in a preferred configuration, one side of the female head is provided as a guide slope, which is pressed outward by the bottom wall of the wedge block when the male and female heads are connected.

[0011] Furthermore, a preferred structure is that the interior of the snap-fit ​​pin groove is provided with an arc-shaped block.

[0012] Furthermore, in a preferred configuration, when the male and female heads are connected, the positioning pin is engaged in the locking pin groove, and the upper part of the positioning pin has a groove that engages with the arc-shaped block.

[0013] The beneficial effects of this utility model are as follows:

[0014] I. In this utility model, the C-type buckle uses a double snap-fit ​​mechanism consisting of wedge blocks, wedge grooves, protrusions, and snap-fit ​​grooves on its male and female heads to ensure the firmness of the C-type buckle after installation and prevent it from falling off after being opened a second time. Furthermore, the mutual snap-fit ​​between the positioning pin and the snap-fit ​​pin groove further improves the installation stability of the C-type buckle and makes it less likely to fall off.

[0015] Second, in this utility model, the silicone pad increases the contact area with the mouse's ear, making the contact closer and more snug, and providing a certain degree of protection. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 A mouse tagger includes a C-shaped buckle 1, with male head 101 and female head 102 at both ends of the C-shaped buckle 1. The male head 101 and female head 102 are interlocked. A protruding wedge-shaped block 3 is provided on one side of the male head 101, and a pair of protrusions 4 are provided on the upper part away from the wedge-shaped block 3.

[0023] Furthermore, a snap-fit ​​groove 9 is provided on one side of the female head 102 to engage with the protrusion 4, and a wedge-shaped groove 5 is provided below it away from the snap-fit ​​groove 9 to engage with the wedge-shaped block 3.

[0024] Furthermore, a pair of positioning pins 7 are provided at the top of the inner wall of the C-shaped buckle 1, and a snap-fit ​​pin groove 6 is provided at the bottom of the inner wall of the C-shaped buckle 1 corresponding to the positioning pins 7. The snap-fit ​​pin groove 6 and the positioning pins 7 are snap-fit ​​mechanisms for each other.

[0025] Silicone pads 8 are provided on the upper and lower ends of the inner wall of the C-shaped buckle 1. When the male and female heads of the C-shaped buckle 1 are connected to each other, the silicone pads 8 are squeezed and contact each other. When the marker is installed on the mouse's ear, the silicone pads 8 provide a certain degree of protection and cushioning, and increase the contact effect with the ear.

[0026] The upper part of the C-shaped buckle 1 is equipped with a marking plate 2, which is used to count, classify and group items.

[0027] One side of the female head 102 is provided as a guide slope 10. When the male and female heads are connected, the guide slope 10 is squeezed by the bottom wall of the wedge block 3 to shift outward.

[0028] The inside of the snap-fit ​​pin groove 6 is provided with an arc-shaped block 11. When the male and female heads are connected, the positioning pin 7 is engaged in the snap-fit ​​pin groove 6. The upper part of the positioning pin 7 is provided with a groove 12, which engages with the arc-shaped block 11, thereby constraining and restricting the positioning pin 7.

[0029] In this embodiment, the opening seam in the middle of the C-shaped buckle 1 is aligned with the mouse's ear and snapped in place. The C-shaped buckle 1 is then pressed firmly at a suitable position. The male head 101 and female head 102 of the C-shaped buckle 1 are connected and snapped together. The positioning pin 7 passes through the mouse's ear and is snapped into the snap-fit ​​pin groove 6. The snap-fit ​​pin groove 6 is snapped into the groove 12 on the outer wall of the positioning pin 7 by the arc-shaped block 11, thereby constraining and limiting the positioning pin 7.

[0030] During the docking process, the wedge block 3 on the male head 101 presses against the guide slope 10 on one side of the female head 102, causing the female head 102 to tilt outward. Then, the wedge block 3 slides into the wedge groove 5 to lock. At this time, the female head 102 resets and fits with the male head 101. Simultaneously, the protrusion 4 and the snap-fit ​​groove 9 snap together. The double snap-fit ​​structure can effectively improve the connection stability of the male and female heads and ensure the installation stability of the marker.

[0031] The use of fine positioning pins 7 can reduce harm to mice and ensure stable installation and positioning.

[0032] Among them, the C-type buckle 1 is made of plastic, which has a certain elasticity and flexibility. When squeezed, it will generate a rebound force at the bend. Through this force, the wedge block 3 can be effectively clamped and engaged with the wedge groove 5. The above-mentioned details are common knowledge to those skilled in the art and will not be explained further.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
