DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nose ring attached to a nose of a cow for identification of the cow.

[0002]

2. Description of the Related Art As a conventional nose ring of a cow, for example, there is a cow nose ring in which a pair of metal half-arc rods are axially attached to each other at one end and the other end is screwed, and the nose septum is not perforated. To mount the nose ring on a cow, first pierce the nasal septum with a piercing tool, insert one of the metal half-arc rods into the perforated hole of the nasal septum, then close the pair of metal half-arc rods and close both ends. They are connected to each other with screws and formed in an annular shape.

[0003] Such a nose ring causes pain to the cow twice when piercing and inserting the nose ring, and the cow is also exposed when a pair of metal half-arc rods are closed and both ends are connected with screws or the like. Therefore, time and labor were required, and workability was not good.

Therefore, for example, one part of a ring made of a hard synthetic resin is separated like a nose ring of a cow described in Japanese Utility Model Publication No. 57-54619, and an arrowhead-shaped piercing rod is attached to one of the separated ends. A connecting portion having an insertion hole to which the piercing rod is connected at the other separated end, inserting the piercing rod into the insertion hole, and attaching the locking step at the base end of the piercing rod to the connecting portion. By engaging the piercing rod and the connecting portion by locking to the formed locking claw, the piercing operation of the septum by the piercing tool becomes unnecessary, and the nose ring is attached to the piercing rod at one end of the ring. As a work that only needs to be inserted into the joint at the end, there is a work that does not require the work of connecting both ends with screws or the like.

[0005]

The method of connecting the locking claw and the locking step as described in Japanese Utility Model Publication No. 57-54619, for example, in order to secure the strength of the nose ring, for example, When the insertion hole formed in the portion has a rectangular cross section, locking claws cannot be formed on all four surfaces of the insertion hole. For example, locking claws are provided on two opposing surfaces.

[0006] For this reason, the connection between the piercing rod and the connecting portion is limited to only the two opposing surfaces. If the nose ring is pulled strongly after the connecting, the locking claw will be turned outward and disengaged from the locking step. And the bonding strength was not sufficient.

An object of the present invention is to eliminate the disadvantages of the above-mentioned conventional example, and it is possible to easily connect the both ends of the C-shaped annular body with one touch, and also to secure a sufficient bonding strength.
An object of the present invention is to provide a cow's nose ring in which the nose ring does not come off after coupling.

[0008]

According to the present invention, in order to achieve the above object, first, a puncture rod is provided at one end of a C-shaped ring made of an elastic body, and the puncture rod is locked at the other end. In a cow nose ring provided with a coupling portion, the tip of the puncture rod is formed in an arrowhead shape, and a locking step portion and a locking projection are provided at a base of the arrowhead portion,
The coupling portion has an insertion hole into which the puncture rod is inserted,
The gist of the invention is that the insertion hole is provided with a locking projection for locking the locking step of the puncture rod and a locking step for locking the locking projection on the puncture rod side.

Secondly, the arrowhead-like part is formed in a quadrangular pyramid shape, and a locking step is formed at one of the upper, lower, front and rear opposing parts of the base of the arrowhead-like part, and is engaged with the other opposing part. A protrusion is provided, the insertion hole is formed in a rectangular cross section, and a locking protrusion for locking the locking step of the puncture rod is provided at an upper or lower or front or rear facing portion of the insertion hole. The invention is characterized in that a locking step for locking the locking projection on the puncture rod side is provided.

Third, the arrowhead-like portion is formed in a triangular pyramid shape, a locking step is formed on two adjacent sides of the base of the arrowhead-like portion, and a locking protrusion is provided on the other side. The insertion hole is formed in a triangular cross section, and a locking projection is provided on two adjacent sides of the insertion hole to lock the locking step of the puncture rod, and the other side has a lock on the puncture rod side. The gist of the invention is to provide a locking step for locking the protruding piece.

According to the first aspect of the present invention, the locking step and the locking projection provided on the side of the puncture rod formed at one end of the C-shaped annular body are connected to the connecting portion formed at the other end. The locking projection is provided on the side of the C-shaped ring and the locking projection is formed on the other end. In order to form the locking step on the side of the connecting portion, it is only necessary to perform processing to remove the portion where the locking protrusion is not provided, and the locking protrusion is weak in terms of strength. Since the pieces do not increase on the same joint side, the joint strength can be improved without reducing the strength of the entire nose ring.

Moreover, the locking projection provided on the side of the puncturing rod is
Since it is inserted into the coupling portion and does not appear to the outside, it is not turned up by an external force to release the lock, and the lock between the puncture rod and the coupling portion is maintained.

According to the second aspect of the present invention, in addition to the above-described operation, when the arrowhead-like portion at one end of the C-shaped annular body is a quadrangular pyramid and the insertion hole at the other end is a square cross section, the arrowhead A locking step and a locking projection are provided at the upper and lower or front and rear facing surfaces of the shape portion and the insertion hole, and the locking step and the locking projection are locked to each other. Thus, the piercing rod and the coupling portion are mutually locked by the locking step portions and the locking projections provided on both sides, respectively, and are locked by each other. In this case, since the shape of the arrowhead-shaped part is a quadrangular pyramid, the surface area is large and it may be difficult to insert it into the septum of the cow, but after insertion and coupling with the coupling part, the upper and lower, front and rear locking step parts Since the locking projection and the locking projection are locked with each other at a total of four positions, the bonding strength is further increased.

According to the third aspect of the present invention, even if the arrowhead-like portion at one end of the C-shaped annular body has a triangular pyramid shape and the insertion hole at the other end has a triangular cross section, the present invention according to the second aspect of the present invention. The locking step and the locking projection are provided in each of the arrowhead-shaped portion and the insertion hole in the same manner as described above, so that the locking step and the locking projection are locked to each other, so that the puncture rod is provided. The locking step and the locking protrusion provided on both sides of the connecting portion and the locking portion are locked to each other, and are locked to each other at each other, thereby increasing the bonding strength. In this case, since the shape of the arrowhead-like portion is a triangular pyramid, the surface area is small, and it is easy to insert into the nasal septum of a cow.

[0015]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a partially cutaway front view showing an embodiment of a cow nose ring of the present invention. A C-shaped annular body 1 constituting the nose ring is made of a flexible synthetic resin such as hard plastic. The puncture rod 2 is provided at one end of the ring-shaped annular body 1, and a coupling portion 3 for locking the puncture rod 2 is provided at the other end.

The tip of the puncture rod 2 is formed in a quadrangular pyramid-shaped arrowhead-shaped part 4 as shown in FIGS. 3 to 5, and at the transition from the main body 1a of the C-shaped annular body 1 to the arrowhead-shaped part 4. The base end of a certain arrowhead-shaped portion 4 is formed in the locking step 5 by reducing the diameter of the arrowhead-shaped portion 4 at the front and rear opposing portions. Further, the front and rear surfaces of a portion between the locking step portion 5 and the main body 1a are formed on a contact surface 10 tapering toward a tip having the same inclination angle as a locking projection 8 described later.

At the upper and lower opposing portions of the base end of the arrowhead-like portion 4, a locking projection 6 having the same inclined surface as the arrowhead-like portion 4 is provided so as to cut out the base end. .

On the other hand, as shown in FIGS. 6 to 8, the connecting portion 3 has a rectangular cross section having a diameter larger than that of the main body 1a of the C-shaped annular body 1, and has a rectangular cross section into which the puncture rod 2 is inserted. An insertion hole 7 having a shape was formed, an opening 3a was provided in a portion facing the front and rear of the insertion hole 7, and a locking projection 8 was provided in the opening 3a. The locking projection 8 protrudes obliquely from the opening end of the insertion hole 7 of the coupling portion 3 such that a plate-like body having an area approximately half the area of the opening 3a is integrally formed with the tip thereof facing the inside of the insertion hole 7. It has elasticity to open outward.

Also, the upper and lower opposing portions of the inner wall of the insertion hole 7 are slightly stepped, so that the diameter of the insertion hole 7 is enlarged, and the locking projection 6 on the side of the puncture rod 2 is locked here. The locking step 9 is formed. In this case, the portion where the locking step 9 is formed in the coupling portion 3 is a portion where the tip of the locking projection 8 is located.

In the figure, reference numeral 11 denotes a holding hole provided at the back of the connecting portion 3 and into which the tip of the puncture rod 2 is inserted.

Next, a method of attaching such a nose ring to the nasal septum of a cow will be described. As shown in FIG. 1, the main body 1 of the C-shaped annular body 1
a is opened, and the puncture rod 2 at one end and the connecting portion 3 at the other end are respectively inserted into left and right nostrils bordering on the nasal septum,
In this state, if the puncture rod 2 and the connecting portion 3 are mutually closed,
The arrowhead-shaped portion 4 at the tip of the puncture rod 2 penetrates through the nasal septum and enters the insertion hole 7 of the connecting portion 3.

The arrowhead-shaped portion 4 enters the insertion portion 7 further into the interior of the insertion hole 7 while pushing the locking projection 8 of the coupling portion 3 outward, and the tip of the locking projection 8 is formed by the arrowhead-shaped portion 4. The locking step 5 of the base is locked, and the tip of the locking projection 6 at the base of the arrowhead-shaped part 4 locks to the locking step 9 on the side of the connecting part 3 to connect the puncture rod 2. It is fixed in the part 3.

At the time of insertion, the locking projection 6 on the side of the puncture rod 2 enters the insertion hole 7 while narrowing against its elasticity,
When the puncture rod 2 enters the inside of the insertion hole 7 and the leading end of the locking projection 6 reaches the enlarged diameter portion formed by the locking step 9, the elastic member repositions and the tip of the locking projection 6 moves. It is locked to the locking step 9.

In the state where the puncture rod 2 is connected to the connecting portion 3, the locking between the locking protrusion 6 and the locking step 9 and the locking step 5 and the locking protrusion 8 are mutually engaged as described above. Further, the locking projection 8 of the connecting portion 3 is brought into close contact with the contact surface 10 on the side of the puncturing rod 2 and pressed, and the tip of the puncturing rod 2 is inserted into the holding hole 11 of the connecting portion 3. Thus, the puncture rod 2 and the connecting portion 3 are firmly connected, and the connection can be confirmed from the outside via the opening 3a.

In the coupled state, even if an external force acts on the locking projection 8 on the coupling portion 3 located on the side of the opening 3a to bend up, the position of the locking projection 8 inside the coupling portion 3 may increase. Since the locking protruding piece 6 is not exposed to the outside, the locking between the locking protruding piece 6 and the locking step 9 is not released, so that the connected state is maintained.

The shapes of the puncture rod 2 and the connecting portion 3 are not limited to the quadrangular pyramid shape as in the above-described first embodiment, but as shown in FIGS. 9 and 10 as a second embodiment. The puncture rod 2 may have a triangular pyramid shape, and the connecting portion 3 may have a triangular cross section.

In this case, for example, the puncture rod 2 is formed such that the locking projection 6 is formed only on the bottom portion, and the coupling portion 3 is formed with a locking step 9 corresponding to this. The locking by the locking protruding piece 6 and the locking step 9 may be performed at one place, but the strength is sufficient.

Further, since the shape of the arrowhead-like portion 4 is a triangular pyramid, the surface area is small, and it can be easily inserted into the nasal septum of a cow.

The shapes of the puncture rod 2 and the connecting portion 3 are not limited to those of the first and second embodiments described above. The shape of the puncture rod 2 may be a hexagonal pyramid, other polygonal pyramids or cones. The cross-sectional shape of the connecting portion 3 may be a polygonal cross-section or a circle corresponding to the shape of the puncture rod 2.

[0030]

As described above, the cow nose ring of the present invention is
The locking step and the locking projection provided on the side of the puncture rod formed at one end of the C-shaped ring are connected to the locking projection and the locking step provided on the side of the coupling portion formed at the other end. Since each is locked, not only the connection by the locking step formed at one end of the C-shaped annular body and the locking projection formed at the other end as in the related art, but also the locking side is locked. In order to form the step portion, it is only necessary to perform a process of slightly removing a portion where the locking projection is not provided, and the strength of the locking projection increases on the side of the same joint portion. Therefore, the bonding strength can be improved without lowering the strength of the nose ring as a whole.

When the arrowhead-like portion at one end and the insertion hole at the other end of the C-shaped annular body have a quadrangular cross-section, respectively, the arrowhead-like portion and the insertion hole are provided at the upper and lower or front and rear opposing surfaces. A locking step and a locking projection are provided on each other, and the locking step and the locking projection are locked with each other, so that the puncture rod and the coupling section are provided on both sides, respectively. The stop portion and the locking projection are locked with each other, and the bonding strength is increased.

Further, since the arrowhead-like portion at one end and the insertion hole at the other end of the C-shaped annular body can each have a triangular cross section, the present invention can be applied to various shapes. In the case of a shape, the surface area is small, and it is easy to insert into the septum of the cow.
