Description

  The present invention relates to a ring for connecting parts used in accessories and the like, in which a ring having a cutout (round ring) and a double ring in the shape of a coil have a tip formed as a plug. The present invention relates to a ring connecting jig for easily connecting a ring (double ring) to other parts such as the example shown in FIG.

  Conventionally, when connecting accessory parts to a round or double ring, grasp the round or double ring with one hand and use the other hand to insert the round or double ring port with pliers or a minus triber. The parts were expanded and the parts were inserted, or a double ring was inserted into the tip of a fixed flat-blade screwdriver to expand the slot and connect other parts.

However, there were the following problems.
If you hold the round or double ring by hand and widen the slot with pliers or a flat-blade screwdriver, or if you widen the slot by inserting a double ring into the tip of a fixed flat-blade screwdriver, If you do not hold the round ring or double ring firmly, the round or double ring will fly away somewhere due to the force to expand the insertion slot, When inserting parts, the round and double rings are displaced by the force they are trying to insert, so that they take off from the tip of a pliers or a flat-blade screwdriver.
The present invention has been made to solve these problems.

  A shape in which a plurality of small-diameter cylinders are stacked stepwise on a large-diameter cylinder for fixing a round or double ring, and a semi-circular cross-section is cut out. A rod-shaped set part with a wedge-shaped recess at the position where the circular ring or double ring of the ridgeline where the cylindrical side intersects stays, and when the double ring is set in the rod-shaped set part, the insertion port is expanded For connecting the circular ring or double ring of the connecting ring used for accessories composed of the insertion tool used for fixing, the fixing part for fixing the set part vertically and the other parts, etc. This is a ring connecting jig.

The ring insertion port is expanded with a ring-shaped round ring or double ring inserted and fixed in a rod body in which a plurality of small diameter cylinders are stacked stepwise on a large diameter cylinder. So, even if it fails to expand, the round or double ring will not fly away from the rod body and will not be lost, but it will also lose the force of expanding and inserting other parts In addition, the insertion port of the ring can be maintained in the expanded state without difficulty, and other parts can be connected easily and quickly. In addition, since a ring-shaped round ring or double can is inserted into a rod body that becomes thinner and narrower as it goes down, it can accommodate a wide variety of sizes from those with a small diameter, and connection between the round ring or double ring and other parts It was possible to solve the conventional drawback of requiring time.

Embodiments of the present invention will be described below.
Since the present invention is a circular or double ring connecting jig, they will be described first. As shown in FIG. 2, (a) is a circular ring in which a single ring main body (1-a) forms a hole (2-a) in the center, and has a notch (3 -A). (B) is a ring-shaped ring body in which a double-coiled ring main body (1-b) forms a hole (2-b) in the center and can be expanded between the double-coiled forms. A gap (4) is provided, and both ends of the ring are insertion ports (3-b).
As shown in FIG. 3, the present invention has a rod-like set part (A) projecting upward for fixing a round ring or a double ring, and when the double ring is inserted into the rod-like set part and set. It is comprised from the insertion tool (B) used in order to expand an insertion port (3-b), and the fixing | fixed part (C) for fixing a set part (A) vertically.
As shown in FIG. 4 (a), the rod-shaped set portion (A) is a rod body (5) having a shape in which a plurality of small diameter cylinders are stacked stepwise on a large diameter cylinder. ) When a round ring hole (2-a) or double ring hole (2-b) with different diameters is inserted into the rod (5) from above as shown in the partially enlarged view of FIG. About half a circle in the cross section is cut out so as to be a space for inserting other parts in the expanded state in the insertion port (3-a) or (3-b). ing. At each position where a double ring with a different diameter stays at one or both of the ridgeline (8-a) and (8-b) where the vertically cut wall surface (6) and the cylindrical side surface (7) intersect A wedge-shaped recess (9) is provided. This concave shape has a shape in which the wedge-shaped tip portion of the insertion tool (B) described later is substantially coincident. The lower part of the rod body (5) is for vertically setting the set part (A), and the position of the recessed part (9) or the cut wall surface (6) is an angle at which it is easy for the operator to work. A square columnar grip (10) is provided so as to be fixed. Even if this grip part (10) is cylindrical, it has a detent, or the wall surface (6) is fixed at an appropriate position by a polygon or a part of the lateral wall having a vertical plane shape. Also good. The set portion (A) may be a conical rod.
The insertion tool (B) is for expanding the insertion port (3-b) by being inserted into the gap (4) of the double ring, and has a thickness of about 1 mm to 3 mm as shown in FIG. The tip of the plate-shaped insertion body (11) has a wedge-shaped insertion part (12) whose thickness is close to zero, and the other end is provided with a handle (13) so that the insertion body can be easily held. Yes. As described above, the insertion portion (12) has a wedge shape that fits into the recess (9) of the set portion (A).
Any material may be used as the material of the insertion body of the set portion (A) and the insertion tool (B) as long as it can withstand the force applied when the circular ring and double ring insertion port (3-b) is expanded.
The fixing part (C) is for fixing the set part (A) vertically, and has an insertion hole (14) for fixing the set part (A) in the upper part as shown in FIG. The cross-section is the same shape as the gripping part (10), the gripping part (10) can be inserted, and the size does not move back and forth and right and left when inserted until the gripping part hits the cylinder with the largest diameter of the rod (5) It has become. In addition, an attachment portion (15) for attaching to somewhere, such as a work table, is provided so that the set portion (A) can be fixed vertically and work can be performed with the set portion (A) inserted. The mounting method is such that it is clamped with commonly used screws. A commercially available vise may be used for the fixing portion (C).
The present invention is configured as described above. When the double ring is used to connect to other parts, the double ring hole (2-b) to be used as shown in FIG. )
When the diameter of the rod (5) stays at a position larger than the inner diameter of the double ring, turn it so that the insertion port (3-b) comes to the wall surface (6) side. In that state, as shown in FIG. 7b, the insertion part (12) of the insertion tool (B) is inserted into the gap (4) of the double ring, and further inserted into the recess (9) of the setting part (A). Insert the part (12) and widen the double-ring insertion port (3-b). After inserting the mounting hole (16) of the part 1 as shown in FIG. 7c into the opened insertion port (3-b)), the double ring body (1-b) is moved in the direction of the arrow as shown in FIG. 7d. To complete the connection. Further, when used for connecting round rings, as shown in FIG. 8a, the hole (2-a) of the round ring is placed on the rod (5) and the insertion port (3-a) of the ring is on the wall surface (6) side. Insert it so that it stays at the position of the thickness of the circular ring, and widen the insertion port (3-a) with pliers or the like as shown in FIG. 8b, and attach the part 2 as shown in FIG. 8c. After inserting the hole (17), the insertion port (3-a) is closed as before to complete the connection.
