Abstract

<P>PROBLEM TO BE SOLVED: To provide a strong pipe tip installing metal fitting easily attachable-detachable without a tool. <P>SOLUTION: A thin construction material having resiliency and strength is molded in a star shape in a diameter a little larger than an inner diameter of a pipe. A biting-in ring 2 forms a specific angle R to respective ones of a star-shaped tip part 7, and is sandwiched between spacers 3, 4 and 5, and is installed on a biting-in ring installing bolt metal fitting 1, and is fastened and fixed by a nut 6. The biting-in ring 2 inclines inside due to the resiliency only by straightly inserting this pipe tip installing metal fitting into the pipe, and the star-shaped tip part 7 of the biting-in ring 2 is fixed in a state of being brought into close contact with a pipe inside surface. When a load is applied to the metal fitting, the biting-in ring 2 tries to push-expand the inside surface of the pipe in a radial shape, and further deeply bites in the pipe inside surface, and can endure a further strong load. <P>COPYRIGHT: (C)2004,JPO

Description

【0001】
【発明の属する技術分野】
本発明はパイプ先端部への機具取り付けのための金具であり、差し込むだけで簡単に取り付けができて、回転させるだけで取り外しができるパイプ先端取り付け金具に関する。
【0002】
【従来の技術】
従来のパイプ先端取り付け金具には、パイプに二枚の半円筒形状に分割された筒を挿入し、ボルト状の金具を回転させてパイプ内部にあるテ−パ状のナットを締め込み、分割された筒をパイプ内部より押し広げて固定する金具や、パイプ先端部に大きな径の筒状の金具を装着してボルトを締め込んで固定する金具。また、クサビ状の金具をパイプ内部に金槌などで叩き込んで固定する金具などがある。
【0003】
【発明が解決しようとする課題】
従来の技術では取り付けに手間を要したり、強度不足や、取り外しが困難であるなどの問題点があるため、工具無しで簡単に着脱できる強度のあるパイプ先端取り付け金具の開発。
【0004】
【課題を解決するための手段】
本課題を解決する手段として、薄くて弾力性と強度のある材質をパイプの内径よりもわずかに大きな径で星形状に成形し、星状の先端部7の一枚ずつに一定の角度Rをつけた食込みリング2をスペーサー3,4,5の間に挟みこみ、食込みリング取り付けボルト金具1に装着してナット6で締め込み、固定する。
【0005】
【発明の実施の形態】
図1に示される実施例では、薄くて弾力性と強度のある材質で星形状に成形し、星状の先端部7の一枚ずつに一定の角度Rをつけて食い込みリング2を成形する。ボルト貫通穴8は太鼓状に加工する。
【0006】
図2に示される実施例ではボルト部9と機具取り付け用台座部10、ストッパー部11が一体化された食込みリング取り付けボルト金具1のボルト部9の側面を平面加工して断面を太鼓状にし、食込みリング2が回転しないようにする。
【0007】
図3、図4、図5、図6に示される実施例ではスペーサー3,4,5のそれぞれの食込みリング2の当たる面を凹面、凸面の球面加工を施し、凸面部は凹面部より小さな径で加工し、パイプに挿入したときの食込みリングの遊び代とする。スペーサーの径はパイプの内径よりもわずかに小さな径で加工し、食込みリング2を保護する。食込みリング取り付けボルト金具1にスペーサー3,4,5と食込みリング2を交互に挟み込み、ナット6で締め付けることによりスペーサー3,4,5の凹凸面で挟まれた食込みリング2は一定の角度で傾き、固定される。
【0008】
【発明の効果】
本発明は以上説明したように構成されているため、以下に記載されているような効果を有する。
【0009】
本発明のパイプ先端取り付け金具をパイプに真っ直ぐに挿入するだけで食込みリング2は弾力性があるため内側に傾き、食込みリング2の星状の先端部7がパイプ内面に密着された状態で固定される。金具に負荷がかかった場合には食込みリング2はパイプの内面を放射状に押し広げようとしてより深くパイプ内面に食い込み、より強い負荷に耐えることができる。
【0010】
食込みリング2の星状のそれぞれの先端部7に一定の角度Rがついているため金具を回転すると、らせん状に金具が移動する。片方向へはより強く食込みリングが食込み、反対方向へ回転させると金具を取り外すことが可能である。
【0011】
着脱のいずれも特別な工具なしで簡単に行え、作業効率を上げることが可能となる。

TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal fitting for attaching a tool to a pipe tip, and more particularly, to a metal fitting for pipe tip which can be easily attached simply by inserting it, and can be removed only by rotating.
[0002]
[Prior art]
In the conventional pipe end fitting, insert two half-cylindrical divided tubes into the pipe, rotate the bolt-shaped fitting, tighten the tape-shaped nut inside the pipe, and split the pipe. A metal fitting that pushes and expands a pipe from inside the pipe, and a metal fitting that attaches a large-diameter cylindrical metal fitting to the end of the pipe and tightens bolts to fix it. Further, there is a metal fitting for fixing a wedge-shaped metal fitting into a pipe by hammering it with a hammer or the like.
[0003]
[Problems to be solved by the invention]
The conventional technology requires a lot of time and effort for installation, lacks strength, and is difficult to remove. Therefore, the development of a strong pipe end fitting that can be easily attached and detached without tools.
[0004]
[Means for Solving the Problems]
As a means for solving this problem, a thin, elastic and strong material is formed into a star shape with a diameter slightly larger than the inner diameter of the pipe, and a fixed angle R is set to each of the star-shaped tips 7. The bite ring 2 attached is sandwiched between the spacers 3, 4, 5, attached to the bite ring mounting bolt 1, tightened with a nut 6 and fixed.
[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
In the embodiment shown in FIG. 1, a star is formed from a thin, resilient and strong material, and the bite ring 2 is formed with a certain angle R at each of the star-shaped tips 7. The bolt through hole 8 is processed into a drum shape.
[0006]
In the embodiment shown in FIG. 2, the side surface of the bolt portion 9 of the bite ring mounting bolt 1 in which the bolt portion 9, the tool mounting pedestal portion 10, and the stopper portion 11 are integrated is made into a drum-shaped cross section, The biting ring 2 is prevented from rotating.
[0007]
In the embodiment shown in FIGS. 3, 4, 5, and 6, the surfaces of the spacers 3, 4, and 5 that are in contact with the biting rings 2 are concave and convex, and the convex portion has a smaller diameter than the concave portion. It is used as a play allowance for the bite ring when it is inserted into a pipe. The diameter of the spacer is slightly smaller than the inner diameter of the pipe to protect the bite ring 2. The spacers 3, 4, 5 and the bite ring 2 are alternately sandwiched between the bite ring mounting bolts 1 and tightened with the nut 6, whereby the bite ring 2 sandwiched between the uneven surfaces of the spacers 3, 4, 5 is inclined at a certain angle. Fixed.
[0008]
【The invention's effect】
Since the present invention is configured as described above, it has the following effects.
[0009]
By simply inserting the pipe end fitting of the present invention straight into the pipe, the bite ring 2 is resilient and tilts inward, and the star-shaped tip 7 of the bite ring 2 is fixed in a state of being tightly attached to the inner surface of the pipe. You. When a load is applied to the metal fitting, the bite ring 2 digs deeper into the inner surface of the pipe in an attempt to radially push the inner surface of the pipe, and can withstand a higher load.
[0010]
Since each star-shaped tip 7 of the bite ring 2 has a certain angle R, when the bracket is rotated, the bracket moves spirally. The bite ring can bite more strongly in one direction and can be removed by turning in the opposite direction.
[0011]
Both attachment and detachment can be easily performed without a special tool, and the working efficiency can be improved.
