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-arc rods are attached to each other at one end, and the other end is screwed, and the nose ring is applied to a calf that has no holes in the nose septum. To install, first pierce the nasal septum with a piercing tool, insert one of the metal semi-arc septa into the hole of the pierced nasal septum, close the pair of metal semi-arc septa 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 even when the pair of metal half-arc rods are closed and the ends are connected with screws or the like. Labor was required and workability was not good.

Therefore, for example, one part of a hard synthetic resin ring is separated like a bovine nose ring described in Patent Document 1 below, and an arrowhead-like piercing heel is provided at one separation end, and the other separation end is provided. A coupling portion having an insertion hole to which the piercing rod is coupled, a piercing rod is inserted into the insertion hole, and a latching claw having a coupling step portion at the base end portion of the piercing rod is formed in the coupling portion. By locking and connecting the piercing rod and the coupling part, there is no need to pierce the nasal septum with a piercing tool, and the nose ring is inserted into the coupling part at the other end of the ring. There is a thing which does not need the operation | work which connects both ends with a screw etc. as what is sufficient for the operation | work only to do.

  Patent Document 2 below compensates for the drawbacks of the coupling method by locking the locking claw and the locking step as described in Patent Document 1. That is, in Patent Document 1, in order to ensure the strength of the nose ring, for example, when the insertion hole formed in the coupling portion has a square cross section, the locking claws are formed on the four surfaces of the entire circumference of the insertion hole. For example, locking claws are provided on two opposing surfaces.

  For this reason, the coupling between the piercing rod and the coupling portion is only at the two opposing surfaces, and if the nose ring is pulled strongly after coupling, the latching claw may turn outward and come off from the latching step, The bond strength was not sufficient.

Japanese Patent Laid-Open No. 2004-133867 has made it easy to insert the nose ring with a single touch as a means to compensate for this drawback. This is because a puncture hook is provided at one end of a C-shaped ring made of an elastic body. In the nose ring of a cow provided with a coupling portion for locking the puncture rod at the end, the tip of the puncture rod is formed in an arrowhead-shaped portion, and a locking step and a locking protrusion are provided at the base of this arrowhead-shaped portion An insertion hole into which the puncture rod is inserted is formed in the coupling portion, and a locking protrusion for locking a locking step portion of the puncture rod and a locking protrusion on the puncture rod side are engaged with the insertion hole. A locking step portion for stopping is provided.
Japanese Patent No. 3030625

  In the conventional example of Patent Document 2, since the locking step portion for locking the locking protrusion on the puncture heel side is provided on the coupling portion side, the peripheral wall portion forming the insertion hole is thick, The opening is also narrow, making it difficult to insert a puncture needle.

  Further, in a state where the puncture heel and the coupling portion are coupled to form the entire C-shaped ring body in a ring shape, an outward restoring force acts on the puncture heel, and this is in a direction to remove the puncture heel from the coupling portion. Therefore, there is a possibility that the puncture heel can easily come off from the coupling portion due to external force or the like.

  The object of the present invention is to eliminate the inconvenience of the conventional example, and to facilitate the insertion of the puncture rod into the coupling portion, thereby improving the workability of the cow's nasal septum. It is intended to provide a bovine nose ring that can convert this into a binding force to the coupling portion even if the sever acts, and the puncture heel is difficult to come off from the coupling portion.

Claim 1 Symbol placement of the present invention, the puncture rod provided at one end of the C-shaped ring body formed of an elastic body, the nose ring of cattle the puncture rod to the other end provided with a coupling portion for engaging the puncture rod The tip of the arrowhead is formed in an arrowhead-like portion, a locking step is provided at the base of the arrowhead-like portion, the coupling portion is formed in an opening with at least one side surface missing, and the insertion hole into which the puncture rod is inserted The left and right side surfaces and the upper or bottom surface are formed as inclined portions corresponding to the cone-shaped inclined surfaces of the puncture rod, and the reduced diameter portion that the locking step portion on the puncture rod side is locked from the inner wall of the insertion hole The gist of the present invention is that a hook-shaped locking projection is formed in a U-shape from the left and right side portions to the upper portion along the inner wall of the opening .

According to the second aspect of the present invention, the U-shaped locking protruding piece is formed in a state where the puncture bar is coupled to the coupling portion and the whole is formed in a ring shape, and the U-shaped curved portion is formed outward or inward of the ring. The gist is to set the formation site so as to be positioned.

The gist of the present invention described in claim 3 is that the U-shaped locking protruding piece protrudes obliquely toward the center of the insertion hole toward the back of the insertion hole.

According to the present invention of claim 1 Symbol placement, a member that binds to puncture rod, because the the locking protrusion protruding from the U-shape along the inner wall of the coupling portion side of the insertion hole, the thickness of the coupling member Can be made thin, and a defect portion can be formed, so that an opening width for inserting the puncture needle can be ensured to facilitate insertion.

  In addition, the nose ring is joined and formed into a ring shape by forcibly pushing the puncture rod into the coupling part using a jig, so that an outward restoring force acts on the puncture rod in the coupled state. As a result, the locking protrusions further bite into the locking step on the puncture rod side, so that the connection between the puncture rod and the coupling portion is further strengthened, and the puncture rod is more difficult to be removed from the coupling portion.

According to the second aspect of the present invention, in a state where the puncture bar is coupled to the coupling portion, the U-shaped locking protrusion has the curved portion located on the outer side or the inner side of the ring, and the opposite side is engaged. There is no stop projecting piece and it becomes a defective part and it is not locked with the locking step part, but this side does not become the direction of action of the restoring force of the puncture needle, so it locks with the locking projecting piece Even if there is no locking with the stepped portion, there is no hindrance to the connection between the puncture rod and the connecting portion.

  In addition, since the defect portion that is not partially provided with the locking projection piece is formed, the opening of the insertion hole is expanded correspondingly, and the puncture rod is easily inserted into the coupling portion.

According to the third aspect of the present invention, since the U-shaped locking protrusion is obliquely projected toward the center of the insertion hole toward the back of the insertion hole, the tip of the locking protrusion is The deeper bites into the base of the locking step and the more the restoring force acts on the locking protrusion, the larger the bite becomes, and the puncture bar becomes difficult to escape from the coupling part.

  As described above, the nose ring of the cow of the present invention can form the opening of the insertion hole formed in the joint part wide, so that it is easy to insert the puncture hook into the joint part and improves the workability of attaching to the nasal septum of the cow. After mounting, even if an outward force due to a restoring force acts on the puncture rod, it can be converted into a binding force for the coupling portion, and the puncture rod is difficult to be removed from the coupling portion.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a longitudinal front view of a coupling portion, which is a main part showing an embodiment of a bovine nose ring of the present invention, FIG. 2 is a front view of the coupled state, FIG. 3 is a front view of the coupled state, and the nose ring is configured. The C-shaped ring body 1 is made of a flexible synthetic resin such as hard plastic, and has a puncture rod 2 at one end and a coupling portion 3 into which the puncture rod 2 is inserted and locked. .

  The puncture rod 2 is formed with a cone-shaped or quadrangular pyramid-shaped arrowhead portion 4 at the tip, and the base of the arrowhead-shaped portion 4, which is a transition portion from the main body 1 a of the C-shaped ring body 1 to the arrowhead-shaped portion 4. The locking step portion 5 is formed with a diameter smaller than that of the shape portion 4.

  As shown in FIG. 7, the coupling portion 3 has an overall shape that is a lateral cross-sectional bowl shape or a substantially rectangular parallelepiped shape having a larger diameter than the main body 1 a of the C-shaped ring body 1, and has an insertion hole 6 into which the puncture rod 2 is inserted. Formed. The insertion hole 6 has a circular or rectangular entrance opening 6a, and the body part 3a of the coupling part 3 to which the puncture bar 2 is inserted and joined is formed in the opening 6b with the upper part being cut off and on the left and right side surfaces. And the bottom face was formed in the inclined part 6c corresponding to the conical inclined surface of the puncture needle 2.

  In the present invention, as the reduced diameter portion that is locked to the locking step portion 5, the entire U-shaped or horizontal U-shaped hook-shaped locking protrusion extends from the left and right side portions to the upper portion along the inner wall of the inlet opening 6 a. A piece 7 was protruded. The locking protrusion 7 is to be locked by the locking step portion 5 of the puncture rod 2. The U-shaped curved portion 7a is formed in a state where the puncture rod 2 is coupled to the coupling portion 3 and formed in a ring shape. The formation site is set so that is located on the outer side of the ring, and the missing part 7b opposite to the curved part 7a is located on the inner side (lower side in FIG. 1).

  The U-shaped locking projection piece 7 is obliquely projected toward the back of the insertion hole 6 toward the center of the hole. Moreover, since the latching protrusion 7 should just be latched by the latching step part 5 as mentioned later, thickness can be made thin.

  Next, a method for attaching the cow's nose ring to the cow's nasal septum will be described. As shown in FIG. 3, the main body 1a of the C-shaped ring 1 is opened, and the puncture rod 2 at one end and the connecting portion 3 at the other end are respectively inserted into the right and left nostrils with the nasal septum as a boundary. If the puncture rod 2 and the coupling portion 3 are closed together in this state, the arrowhead-like portion 4 at the tip of the puncture rod 2 breaks through the nasal septum and enters the insertion hole 6 of the coupling portion 3.

  At this time, the arrowhead-like portion 4 enters the inside main body portion 3a so as to push the locking projection piece 7 projecting through the inlet opening 6a rearward, and the locking projection piece 7 Since the lower portion is the defect portion 7b, there is no portion that is caught when the arrowhead-like portion 4 is inserted in this portion, and the width of the inlet opening 6a is widened so that the arrowhead-like portion 4 is smoothly inserted. Further, since the locking protrusion 7 itself is also thinly formed, it can be easily spread by the arrowhead-shaped portion 4, and from this point, the insertion of the arrowhead-shaped portion 4 is facilitated.

  In the state where the arrowhead-like portion 4 is inserted into the insertion hole 6 and joined to the main body portion 3a, the tip of the locking protrusion 7 is locked to the locking step portion 5 on the puncture bar 2 side. At this time, since the locking protrusion 7 protrudes obliquely inward toward the back of the insertion hole 6, the locking protrusion 7 is locked so as to pierce toward the base of the locking step 5.

  Further, since the puncture rod 2 and the coupling portion 3 are forcibly formed into a ring shape using a jig, the puncture rod 2 is pulled out of the coupling portion 3 in the coupled state, i.e., FIG. In 2, an outward (arrow direction) restoring force acts.

  This restoring force (force to return to the original shape) is the strongest force acting on the upper side and hardly applied on the lower side, so the force acting on α (upper) in FIG. Almost no side. The puncture rod 2 is locked to the locking protrusions 7 at a total of three locations, the upper side α and the left and right sides β and γ, and is securely fixed to the coupling portion 3 and can maintain a ring shape.

  Further, when the puncture rod 2 is pulled in the direction of arrow A in FIG. 1 by this restoring force, the locking protrusion 7 further bites into the locking step portion 5 on the puncture rod 2 side. And the puncture rod 2 is more difficult to come out from the coupling portion 3.

  The lower part of the locking protrusion 7 is a defect part 7b. However, since the restoring force of the puncture rod 2 does not act in this direction, the puncture is performed even if the locking protrusion 7 does not exist in this lower part. There is no hindrance to the coupling between the heel 2 and the coupling portion 3.

  FIGS. 8-10 shows 2nd Embodiment of this invention, The main-body part 3a of the coupling | bond part 3 lacked the lower part, and was formed in the opening 6b. Note that the left and right side surfaces and the bottom surface are formed in the inclined portion 6c corresponding to the conical inclined surface of the puncture rod 2, which is the same as in the first embodiment.

  In this case, the missing portion 7b of the locking projection piece 7 may be provided on the upper side, but it may be provided on the lower side unlike the illustrated case.

  That is, as shown in FIG. 11, the U-shaped hook-shaped locking protrusion 7 protrudes from the left and right sides to the top along the inner wall of the inlet opening 6a, but the missing portion on the opposite side of the curved portion 7a. 7b may be located on the inner side (lower side in FIG. 9) of the ring.
