Description

[Detailed description of the invention] Industrial field of application: This invention is used when a relatively thin wire is used to wrap an object around an object, such as when attaching a display board to a communication pole using a thin wire. The present invention relates to a fastening device that is particularly effective for use.

Conventional technology and purpose: Conventionally, in order to wrap wire around an object, it is common to pinch both ends with pliers and twist. They often become relaxed and fail to achieve their goals. The present invention was devised with the aim of resolving these inconveniences of the conventional method.

Embodiment: The present fastener has a hollow part 2 in the center having large, medium and small diameter hollow parts 2', 2'', 2, and a ratchet-operated internal gear 3 is formed near the lower end. A rotor 4 with a knob 5 that fits into the base 1 and the hollow portion 2 rotatably as described below.
and a ratchet-operated pawl member 7 which tightly fits into the corner portion 6 of the rotor. The claw 7' of this claw member 7 is fitted into the above position,
When the rotor 4 is fitted into the hollow portion 2 of the base body 1, it meshes with an internally toothed ratchet 3 of the base body. Reference numeral 8 denotes a vertical groove provided on the upper surface of the base body, which is used to pass a target wire as described later. The rotor 4 consists of large, medium, and small diameter circular portions 4', 4'', 4, a corner portion 6, and a retaining protrusion 9 in order from the top.The medium diameter circular portion 4'' has a passage passing through it. A hole 10 is bored, and a common vertical groove 11 is formed between the protrusion 9 at the lower end and the corner 6, so that when the claw member 7 is tightly fitted into the corner 6 from below, These elements are made to be elastic. It is clear that such a configuration can prevent the rotor 4 from coming off when it is fitted into the base body. When the rotor 4 is fitted as described above, the rotor 4 is made to be able to rotate with the knob 5, but in the middle of rotation, the vertical groove 8 is made to communicate with the through hole 10 of the medium diameter circular portion 4'', This passage is also formed in a relational manner so as to communicate with an annular cavity 12 formed between the medium-diameter hollow portion 2'' of the base body 1 and the medium-diameter circular portion 4'' of the rotor 4. A pair of pinch plate parts are integrally formed on the part, and are provided so that it is convenient to simultaneously pinch these plate parts with fingertips and apply them to the object to be tightened when tightening with this tool.14 is a base body. Two pairs of legs, one on the left and one on the right, protrude diagonally downward outward from 1, and these legs are located between the object to be tightened and the base 1 and act as elastic bodies, thereby The shape, material, and position are selected to meet this purpose so that the fastening can be maintained even more firmly.

This device is used as follows. That is, in the above-described fitted state between the hollow portion of the base 1 and the rotor 4, first rotate the rotary knob 5 to a position where the vertical groove 8 and the through hole 10 communicate with each other, and then insert both ends of the target wire into this groove. 8 and hole 10 from the left and right respectively, and by rotating the knob 5, the inserted wire is wrapped around the rotor's medium diameter circular part 4'' and tightened to the target object, and in the final stage, the nail 7' meshes with the internally toothed ratchet 3, and the tightening is completed.This tightening may be done as follows: Insert one end of the target wire from one side through the groove 8 and the hole 10, and then tighten the knob 5. Rotate 180 degrees to wrap the insertion wire around the 4" medium diameter circle, then insert the other end in the same way as far as it will go, and turn the knob to tighten it more quickly. . The mode of use of this tool is shown in FIG. In the figure, a indicates the target wire, b the target object (telephone pole display board), and c the object to be tightened (telephone pole).

Effects of the invention: Unlike conventional tightening means, this device not only does not have the inconvenience of breaking or loosening even when the wire is thin, but it is also easy to operate because the operation can be completed by simply rotating the knob 5. It has the advantage that it is simple and requires less work, and that it can be provided at a low cost because it can be easily molded if each part is made of plastic.

Claims (1)

[Claims for Utility Model Registration] (1) A hollow part 2 having large, medium, and small diameter hollow parts 2', 2'', and 2 in order from the top in the center, and a ratchet-operated internal tooth near the lower end. A ratchet wheel 3 has a base 1 in which a vertically divided groove 8 is formed at the upper end; and a rotation knob 5 on the upper surface of the upper end;
Medium and small diameter circular parts 4', 4'', 4, corner parts 6,
The rotor 4 is provided with a retaining protrusion 9 and has a through hole 10 formed in a medium diameter circular portion 4''; is rotatably fitted into the hollow portion 2 of the base body 1 from above, and the ratchet-operated pawl member 7 is fitted into the corner portion 6 of the rotor 4 from below under pressure. During assembly, as the knob 5 is rotated, the through hole 10 communicates with the vertical groove 8 and the annular cavity 12 formed between the medium diameter hollow part 2'' and the medium diameter circular part 4''. , a wire fastening tool in which a common longitudinal groove 11 is formed in the corner portion 6 and the retaining protrusion 9. (2) The leg portion 14 is connected to the base body 1 when tightening the target wire. The wire fastening tool according to claim 1, wherein the shape, material and arrangement are selected so that the wire fastening tool is located between the body and the body and acts as an elastic body, thereby maintaining the fastening even more firmly.
