Description

  The present invention relates to a nose ring attached to a cow's nose for identification of the cow.

  As a conventional cow's nose ring, for example, a pair of metal half-solders are attached to each other at one end, and the other end is screwed, and the nose ring is applied to a calf that is not perforated in the nasal septum. To install, first pierce the nasal septum with a punch, insert one of the metal semi-isolates into the hole in the pierced nasal septum, close the pair of metal semi-isolates, and connect both ends with screws etc. It is formed in an annular shape.

  Such a nose ring causes pain to the cow twice during drilling and insertion of the nose ring, and the cow is exposed to the work of closing a pair of metal semi-solitudes and connecting both ends with screws etc. The workability was not good.

  Thus, for example, a bovine nose ring is proposed in which a C-shaped ring body made of an elastic body is provided with a piercing heel at one end and a coupling portion to which the piercing heel is locked at the other end (see, for example, Patent Document 1). ).

  As shown in FIGS. 8 to 10, one part of the hard synthetic resin ring is separated to form a C-shaped ring body 1, and an arrowhead-shaped piercing heel 2 is formed at one separation end, and the other is formed. A coupling portion 3 having an insertion hole 5 to which the stabbed heel 2 is coupled is formed at the separation end, the stabbed heel 2 is inserted into the insertion hole 5, and a locking step 2 a at the base end of the stabbed heel 2 is coupled to the coupling portion 3. The puncture rod 2 and the coupling portion 3 are coupled to each other by engaging with the engagement portion 3a formed in the above, so that the puncture operation into the nasal septum with a puncture device is not necessary, and the end of the ring is also attached to the nasal ring 2 As a result, it is not necessary to connect the both ends with screws or the like.

In the figure, reference numeral 4 denotes a hole for demolding at the time of molding, which is formed at a position outside the C-shaped ring body 1.
Japanese Patent Publication No. 56-31083

  Although the conventional piercing needle is formed in a conical arrowhead shape, its surface is smooth as shown in FIG. Therefore, when trying to pierce the nasal septum of a cow with this puncture needle, the puncture puncture enters between the cell membranes of the nasal septum and cannot completely puncture the nasal septum when engaging the piercing fold with the coupling part. As a result, the stabbed spider and the coupling portion cannot be completely coupled, and there is a possibility that they will come off if they are used as they are.

  Further, since the punched hole is formed at the position on the outer peripheral surface side of the C-shaped annular body, the C-shaped annular body piercing pit in a state where the piercing ridge and the coupling portion are coupled to the cow's nose. A repulsive force (relocation force) due to elasticity is generated in the coupling portion, and the repulsive force is applied in the direction of the hole that is the opening. As a result, the punched hole always receives a repulsive force, and if the strength is insufficient, the nose ring may be damaged from this portion.

  Furthermore, with the C-shaped ring attached to the nose of the cow as shown in FIG. 11, the hole is always downward, so when the cow eats food, it is rubbed in contact with the ground, etc. As a result, there was a problem that the portion of the hole outside the C-shaped ring body was worn and the joint portion was easily broken.

  The object of the present invention is to eliminate the inconvenience of the conventional example, and can completely penetrate the nasal septum of the cow with a stabbing spear so that it can be securely coupled to the coupling part, and there is no risk of detachment after wearing. An object of the present invention is to provide a bovine nose ring that can improve reliability without fear of damage to a portion.

The present invention achieves the above-mentioned object, and the invention according to claim 1 is a coupling in which an arrowhead-shaped piercing bar is provided at one end of a C-shaped annular body made of an elastic body, and the piercing bar is locked at the other end. In the nose ring of the cow in which a portion is provided and a cutter portion for preventing the entanglement of meat pieces is formed on the surface of the stabbed heel, a hole is opened in the coupling portion positioned on the inner peripheral surface side of the C-shaped ring This is the gist.

  According to the first aspect of the present invention, when piercing the stabbing sput into the nasal septum of the cow, it is possible to completely pierce the nasal septum with the cutter part formed on the surface, so that the meat piece is not involved when inserted, The stabbing heel can be completely coupled to the coupling portion, and there is no risk of detachment after mounting.

Then, by setting the opening position of the punched hole to the inner peripheral surface side of the C-shaped ring body, the repulsive force (relocation force) due to the elasticity of the C-shaped ring body in the mounted state where the piercing heel and the coupling portion are combined. ) Acts in the direction of the outer peripheral surface at the joint location, the punched hole is not opened in the outer peripheral surface, so that the strength of this portion can be increased and damage can be prevented. Moreover, even if the cow eats food, even if the outer peripheral surface portion of the coupling portion comes into contact with the ground and rubs, there is little risk of breakage.

As described above, since the nose ring of the cow of the present invention is provided with the cutter portion on the piercing heel, it can prevent the meat piece from being caught at the time of insertion, and can completely penetrate the nasal septum of the cow with the piercing heel. It can be reliably coupled to the coupling portion, and there is no possibility of detachment after mounting, and there is no possibility that the coupling portion is damaged in the mounted state, so that the reliability can be improved. And by making the opening position of a punch hole into the inner peripheral surface side of a C-shaped ring body, the intensity | strength of this part can be raised and damage can be prevented. Moreover, even if the cow eats food, even if the outer peripheral surface portion of the coupling portion comes into contact with the ground and rubs, there is little risk of breakage.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Figure 1 is a front view showing an implementation form of nose ring cow present invention, a plan view of a portion of the piercing rod 2 is ditto essential part, FIG. 3 is a side view of the coupling portion is same as above essential part, bovine Since the entire configuration of the nose ring is the same as that of the conventional example already described with reference to FIGS. 8 to 10, the same reference numerals are assigned and detailed description thereof is omitted.

  The C-shaped ring body 1 constituting the nose ring is made of a flexible synthetic resin such as hard plastic. The C-shaped ring body 1 is provided with a piercing bar 2 at one end and the piercing bar 2 is engaged with the other end. A coupling part 3 for stopping is provided.

The piercing rod 2 is formed in a conical arrowhead shape as a whole at the tip, and the ridges 6 remain in a plane cross shape along the inclination of the cone on the outer surface of the cone-shaped portion. A recess 7 is formed by a notch, which is a first example of the cutter part .

  Thereby, the edge of the protrusion 6 functions as a cutter part.

  A locking step 2a is formed at the base end of the arrow-like substantially conical portion so as to reduce the diameter of the base end.

  The coupling portion 3 has an overall shape that is larger than the main body 1a of the C-shaped ring body 1 in a bowl shape or a quadrangular shape, and forms an insertion hole 5 into which the piercing rod 2 is inserted. A locking portion 3a to be locked by the locking step portion 2a formed on the piercing bar 2 is formed.

  The hole 4 for demolding at the time of molding is formed on the inner circumferential surface side of the C-shaped ring body 1 and is formed inside the coupling portion 3. Thereby, as shown in FIG. 3, the outer circumferential surface side of the C-shaped ring body 1 is formed thick without the punched hole 4.

  Next, a method for attaching such a nose ring to the nasal septum of a cow will be described. With the main body 1a of the C-shaped ring body 1 opened, the piercing rod 2 at one end and the connecting portion 3 at the other end are respectively inserted into the left and right nostrils with the nasal septum as a boundary. If the joint part 3 is mutually closed, the arrowhead-like substantially conical shape part at the tip of the piercing spear 2 breaks through the nasal septum and enters the insertion hole 5 of the joint part 3.

  At this time, since the protrusion 6 is formed in the advancing direction along the inclination on the outer peripheral surface of the puncture needle 2, the edge of the protrusion 6 functions as a cutter part and completely cuts the cell membrane of the nasal septum. Therefore, the piercing heel 2 completely penetrates the nasal septum without involving a piece of meat, the locking step 2a of the piercing heel 2 is securely locked with the locking portion 3a of the connecting portion 3, and the piercing heel 2 is connected to the connecting portion 3. Fully combined.

  In the coupled state, the hole 4 is positioned on the inner peripheral surface side of the main body 1a, and a force (repulsive force) for opening the coupling portion 3 outward from the side of the piercing heel 2 is applied to the coupling portion 3 by the elasticity of the main body 1a. However, since this force is not applied to the opening side of the hole 4, there is no possibility of breakage from the position of the hole 4 due to insufficient strength.

  Further, since the hole 4 is facing upward when the nose ring is worn, the cow does not rub against the ground or the like when it eats food, and is not easily damaged.

4 and 5 show a second example of the cutter portion, and the shape of the cutter portion formed on the piercing heel 2 is penetrated by a notch formed on the surface of an arrowhead-like conical shape portion along an inclination from an opposing position. The hole 8 was formed in a tunnel shape.

Thereby, the location of the edge of the through-hole 8 formed from the surface of a cone-shaped part functions as a cutter part. Other configurations are the same as those of the above embodiment .

In order to attach such a nose ring to the nasal septum of a cow, as in the first example , the substantially conical shape portion at the tip of the piercing lance 2 is penetrated through the nasal septum to enter the insertion hole 5 of the connecting portion 3, thereby And the connecting part 3 are connected.

  At this time, since the through-hole 8 is formed in the traveling direction along the inclination on the outer peripheral surface of the puncture needle 2, the edge of the through-hole 8 functions as a cutter part and completely cuts the cell membrane of the nasal septum. Therefore, the piercing heel 2 completely penetrates the nasal septum without involving a piece of meat, the locking step 2a of the piercing heel 2 is securely locked with the locking portion 3a of the connecting portion 3, and the piercing heel 2 is connected to the connecting portion 3. Fully combined.

  In the coupled state, the punch hole 4 is located on the inner peripheral surface side of the main body 1a, and due to the elasticity of the main body 1a, a force (repulsive force) that attempts to open the coupling portion 3 from the side of the piercing spear 2 to the outside. Even if it is applied, this force is not applied to the opening side of the hole 4, so there is no risk of breakage from the position of the hole 4 due to insufficient strength.

  Further, since the hole 4 is facing upward when the nose ring is worn, the cow does not rub against the ground or the like when it eats food, and is not easily damaged.

FIGS. 6 and 7 show a third example of the cutter part. As a cutter part to be formed on the stab cage 2, a ring-shaped notch 9 is formed along the circumferential direction on the surface of the stab cage 2. The ring-shaped notch 9 is formed in two stages in the illustrated example, and the edge of the notch 9 has a cutter function. Other configurations are the same as those of the above embodiment .

In order to attach such a nose ring to the nasal septum of a cow, the substantially conical shape portion at the tip of the piercing heel 2 is penetrated through the nasal septum and enters the insertion hole 5 of the coupling portion 3 in the same manner as in the first and second examples. The piercing heel 2 and the coupling part 3 are connected.

  At this time, since the notch 9 is formed along the circumferential direction on the outer peripheral surface of the puncture needle 2, the edge of the notch 9 functions as a cutter, and completely cuts the cell membrane of the nasal septum. At the same time, the nasal septum is absorbed into the recess formed by the notch 9. Therefore, the stabbed heel 2 completely penetrates the nasal septum without involving a piece of meat, the locking step 2a of the stabbed heel 2 is securely locked with the locking portion 3a of the coupling part 3, and the stabbed heel 2 is connected to the coupling part 3. Fully combined.

  Since the operation by setting the formation position of the punch hole 4 to the inner peripheral surface side of the main body 1a is the same as in the first and second embodiments, the description thereof is omitted here.
