【考案の詳細な説明】 本考案は油圧ホース接続口金に関する。[Detailed explanation of the idea] The present invention relates to a hydraulic hose connection cap.

油圧ホース接続口金は、自動車や各種機械の油
圧ホース接続部において油圧ホースと金属管とを
接ぎ合わせるために使用されるものであつて、例

Hydraulic hose connection caps are used to connect hydraulic hoses and metal pipes in the hydraulic hose connections of automobiles and various machines, and are also described in, for example, Japanese Patent Publication No. 44-997, filed by the applicant of the present application. As disclosed, this has been widely known.

ところが、従来の油圧ホース接続口金は、口金
本体と該口金本体の中心部に挿入される油管とを
ロウ付け等により完全に固定したものであるため
次のような欠点が見出された。
However, the conventional hydraulic hose connection cap has the following drawbacks because the cap body and the oil pipe inserted into the center of the cap body are completely fixed by brazing or the like.

第1の欠点は、油圧ホース接続口金の一側に螺
着される金属管の中心と油圧ホース接続口金の油
管の中心とを正確に芯出しする必要性(もしも正
確に芯出しされていないと、金属管と油管との円

際および口金本体と油管との組み付けの際にきわ
めて厳格な加工精度および組み付け精度が要求さ
れ、これが製品の歩留まりの低下ひいては製造コ
ストの上昇を招いたことである。
The first drawback is the need to accurately center the center of the metal pipe screwed onto one side of the hydraulic hose connection cap and the center of the oil pipe of the hydraulic hose connection cap. (This can cause misalignment of the conical joint surface between the metal pipe and the oil pipe, causing oil leakage.) Therefore, extremely strict procedures are required when machining the oil pipe insertion hole and threaded part of the base body, and when assembling the base body and oil pipe. High processing accuracy and assembly accuracy are required, which has led to a decrease in product yield and, in turn, to an increase in manufacturing costs.

第2の欠点は、ロウ付け等による熱によつて口
金本体および油管に材料組織の変化および強度の
低下が生じ、特に油圧ホースをカシメてホース接

うという欠陥が生じ易いことである。
The second drawback is that the heat from brazing etc. causes changes in the material structure and decrease in strength of the base body and oil pipe, and the oil pipe may be crushed, especially when caulking the hydraulic hose and fastening it to the hose connection base. This defect is likely to occur.

第3の欠点は、ホース接続口金に防錆のための
表面メツキ処理を行なう際、既に口金本体と油管
とが一体化されていると、メツキ液がホース接続
口金の中央部(口金本体の油管挿通孔に油管が挿

ある。
The third drawback is that when performing surface plating treatment on the hose connection cap for rust prevention, if the cap body and the oil pipe are already integrated, the plating liquid may be applied to the center of the hose connection cap (the oil pipe of the cap body). Since the oil pipe is inserted through the insertion hole, it is difficult to wrap around the hole (which is a blind part), and the rust prevention treatment is likely to be incomplete.

従つて本考案の目的は、これらの欠点をすべて
解決できるホース接続口金を提供することであ

The object of the invention is therefore to provide a hose connection cap which can overcome all these drawbacks.

That is, the inner diameter of the oil pipe insertion hole (through hole) of the mouthpiece body is formed to be larger than the outer diameter of the oil pipe, and the oil pipe is inserted into the through hole so as to be movable in the radial direction (that is, by a loose fit). On the other hand, since the structure is such that the oil pipe is supported against the mouthpiece body by press-fitting an elastic plate with a hole with an inner diameter smaller than the outside diameter of the oil pipe into the oil pipe from the hydraulic hose connection side, When a force acts on the oil pipe, the oil pipe has a degree of freedom in which it can move radially in the through hole with respect to the base body, so that when screwing the metal pipe to be connected to the hydraulic hose connection base, the metal Even if there is a slight misalignment between the center of the pipe and the center of the oil pipe, the oil pipe can move according to the self-centering effect of the conical joint surface provided on the metal pipe and the oil pipe (see above). Elimination of drawback 1), no change in the material structure or reduction in strength of the base body and oil pipe because heating work such as brazing is not performed (resolution of drawback 2 above), and attachment of the oil pipe to the base body Since rust-preventing treatment can be applied to each piece beforehand, it is possible to eliminate incompletely-treated rust-preventing portions (elimination of drawback 3 above).

Before explaining the hydraulic hose connection cap of the present invention, a conventional hydraulic hose connection cap 10 will be explained based on FIG. In general, the hydraulic hose connection cap 10 includes a cap body 12 and an oil pipe 14 inserted through the center of the cap body 12. The mouthpiece body 12 includes a portion for caulking and fastening the hydraulic hose 16, that is, a hydraulic hose fastening portion 18;
It includes a part for screwing the metal tube 20 shown in FIG. 3 with a nut 22, that is, a metal tube screwing part 24,
A partition portion 26 extending radially inward is provided between the two portions 18 and 24, and a through hole 28 is formed in the partition portion 26 to communicate the two portions 18 and 24.

When connecting the hydraulic hose 16 and the metal pipe 20 using such a hydraulic hose connection cap 10,
In order to prevent oil leakage, the oil pipe 14
a conical outer surface 14' formed at the end of the metal tube 20; and a conical inner surface 2 formed at the end of the metal tube 20.
0' must be positioned so that they are in complete contact with each other. However, in the conventional hydraulic hose connection cap 10 shown in FIG.
The oil pipe 1 is inserted into the through hole 28 formed in the partition part 26 of
4 was inserted tightly and the two were fixed by brazing. Therefore, if the machining accuracy and assembly accuracy of the through hole 28 were low, the center of the oil pipe 14 and the center of the metal pipe 20 would not align accurately, and the two would conical surface 14',
Oil leakage occurred because 20' did not fit tightly. In addition, the material of the oil pipe 14 becomes particularly weak due to heating during brazing, and the oil pipe may be crushed when the hydraulic hose fastening part 18 is caulked, and the plating liquid may not easily flow into the central blind part 29 of the mouthpiece body 12, thereby preventing rust. The problem was due to inadequate processing.

In the hydraulic hose connection cap 30 of the present invention, the oil pipe 1
4 is inserted into the through hole 28 of the base body 12 so as to be movable in the radial direction with an arbitrary loose fit. Furthermore, as shown in FIG.
The oil pipe 14 is connected to the mouthpiece body 12 by pressing the elastic plate 34 against the partition 26 through the
I support it. The elastic plate 34 can be made of a suitable metal or plastic, and preferably has slits formed at appropriate intervals around the hole 32 as shown.

As described above, the hydraulic hose connection base 3 of the present invention
0, since the oil pipe 14 is movably inserted in the radial direction with respect to the through hole 28 of the base body 12, when the metal pipe 20 is screwed, there is a gap between the center of the metal pipe 20 and the center of the oil pipe 14. Even if there is some misalignment in
Since the oil pipe 14 can be moved in the radial direction within the through hole 28 due to the self-centering action of the conical joint surfaces of the two, there is no need for particularly strict precision in processing and assembling the hydraulic hose connection mouthpiece 30. , the oil pipe 14 and the metal pipe 20 can be connected without oil leakage. In addition, since heating work such as brazing is not required, weakening of the oil pipe 14 is prevented, and even if the hydraulic hose fastening portion 18 is caulked, the oil pipe 14
4 will not be crushed. Furthermore, since the base body 12 and the oil pipe 14 can be assembled together after being separately plated to prevent rust, no incompletely plated portions will remain.
