Description

[Detailed explanation of the invention] (Purpose of the invention) The invention is based on identifying laboratory animals such as rabbits and rats and carrying out experiments in laboratories and test laboratories.
Regarding the reactions and behaviors of individual animals, especially the marker rings used to identify individual animals when observing them over a long period of time.

Traditionally, animals such as mice, rats, and rabbits have been identified by writing on their ears with a magic pen, or by using an identification ring that bends inward. The inward-bending identification ring, which is inserted into a hole in the end and folded inward, also has the disadvantage that it can fall off if the animal moves or scratches its ear.

The present invention improves these shortcomings of conventional identification rings and provides a safe indicator ring that will not fall off even when the animal moves violently, and will not cause injury if the animal runs over it. be.

(Structure of the invention) That is, in the present invention, a belt-shaped plate for displaying identification is bent at approximately the center thereof, one end of the belt-shaped plate is inserted into a hole provided at the other end, and the other end is inserted into a hole provided at the other end. This is an animal tag ring that is bent outward toward the tip and fixed to the animal's ear.

The present invention will be described in detail based on embodiments shown in the drawings. 1 to 4 show a marking ring 1 for animals according to the present invention, and FIG. 5 shows a fixture for fixing the marking ring 1 to an animal's ear.

Marker ring 1 as shown in Figures 1 and 2
is a band-shaped plate having a bending part 2 to be pre-bent and a tongue lower end 5, the rear end part 3 has a perforation 4, and the other end has a tip tongue part 6 penetrating through the perforation 4 on the inner side. It is temporarily bent and installed.

As shown in FIGS. 3 and 4, the band-shaped marker ring 1 is divided into a front piece 7 and a back piece 8 by a preliminary bending part 2. Then, by pressing the pieces 7, 8 and the tip tongue 6 from the outside, the tip tongue 6 pierces the animal's ear a and passes through the perforation 4, and is bent outward toward the rear end 3. and secured to the animal's ear.

It is easier to insert the tip of the tip tongue 6 into the borehole 4 if it is thin and pointed, and the rear end 3 has a length that allows the tip tongue to be bent and fixed.
The indicator ring 1 is preferably made of a metal plate, such as stainless steel, which is hard to corrode and is easy to bend, and the front piece 7 and the back piece 8 can be stamped with symbols and numbers for classification and identification. Furthermore, by baking special paint, classification and identification by color is also possible.

FIG. 5 shows an example of a fixture b that can easily fix the marking ring 1 to an animal's ear. The fixing tool is, for example, in the shape of a pair of pliers, and one of the clamping blades 9 and 10 that fit into each other has a fitting recess 11 for bending the tip tongue 6, and a fitting recess 11 for bending the tip tongue 6. A holding groove 12 for holding the main body is provided, and the other clamping blade 10 is provided with a protrusion 13 projecting in the shape of a hook whose purpose is to maintain the tip tongue 6 at a substantially right angle and insert it into the borehole 4. form.

The fitting recess 11 has a distal tongue portion 6 that passes through the perforation 4.
The fitting recess 11 is recessed by the bending space of the tip tongue 6 in order to bend outward toward the rear end 3 of the marker ring 1, and the protuberance provided at the position facing the clamping blade 10 The rear end portion 3 is fitted with the rear end portion 13.
It presses on.

The raised portion 13 serves to guide the tip of the distal tongue portion 6 so that it first bends outward toward the rear end portion 3 side after passing through the perforation (the state shown in FIG. 6, B), and to It plays the role of supporting 3.

The holding groove 12 forms a space for holding the main body of the marker ring 1, that is, the front piece 7 and the back piece 8 that are bent through the bending part 2, and forms a space for holding the main body of the marker ring 1, that is, the front piece 7 and the back piece 8 that are bent through the bending part 2. Alternatively, grooves may be formed on both sides.

14 is a support shaft that supports the clamping blades 9 and 10, and 15 is a handle of the pliers.

When the indicator ring 1 is held between the fixed pliers constructed in this way as shown in Fig. 6, and the animal's ear is further inserted and the pliers are tightened, the tip tongue 6 is bent and securely fixed to the ear. .

(Effect of the invention) The mark ring 1 fixed in this way is bent outward as soon as its tip tongue 6 passes through the perforation 4, so that it bends outward along the rear end 3. It can be bent without any gaps and can be fixed without loosening.

In contrast, those that are bent inward (toward the surface piece 7) tend to be bent by moving away from the surface piece 7 and making a large turn, as shown in FIG. This is because the force applied as a flow of mechanical force on the band-shaped plate is more natural and easier to bend when directed outward (towards the rear end 3). Since the pressing force from both clamping pressure blades of the pliers is applied to each other, it is strongly tightened and is extremely effective for bending, but as shown in Fig. The raised part 1
3' is not located in the bending direction of the tip tongue 6, so the tip tongue 6 is only pressed by the fitting recess 11', and the force applied thereto is weak.

In contrast, the inwardly bent ring, which has a large bend, is likely to loosen and fall off, but in contrast, the indicator ring 1 of the present invention is fixed without loosening, so it does not fall off, and it is easy to use with fixing pliers. It can be easily attached to an animal's ear and is extremely practical.
