号）とがある。 Hydraulic hose connection ferrules are used in the hydraulic hose connections of automobiles and various machines.
Broadly speaking, there are types used to join hydraulic hoses and metal pipes (for example,
No. 997) and those of the type used to join hydraulic hoses together (for example, Japanese Patent Laid-Open No. 18626
No.).

ことにもなつていた。 However, regardless of the type of hydraulic hose connection cap, in conventional ones, the cap body and the oil pipe inserted through the center of the cap body are completely fixed by brazing or the like, so they cannot be used interchangeably. In order to accurately center the metal pipes and hydraulic hoses that are to be joined together, or between the hydraulic hoses, extremely strict attention must be paid to the machining accuracy of the base body, the accuracy during brazing, etc. . This is because if the machining accuracy is low, it may cause cracks in the hydraulic hose or cause oil leakage.
Furthermore, the requirement for high processing accuracy has led to a decrease in product yield and, in turn, to an increase in manufacturing costs.

である。 The applicant has already filed a utility model registration application (filed on November 16, 1982) for a hydraulic hose connection cap that connects a hydraulic hose and a metal pipe and can eliminate the above drawbacks. However, the present application relates to a hydraulic hose connection fitting that connects two hydraulic hoses.

Become. Therefore, it is possible to connect the hydraulic hose without eccentricity, without requiring particularly strict machining accuracy unlike conventional hydraulic hose connection caps.
以下、本考案の油圧ホース接続口金について、
添付図面に基き説明する。 Below, regarding the hydraulic hose connection base of this invention,
The explanation will be based on the attached drawings.

ース１６同士を接続するものである。 FIG. 1 shows the cross-sectional structure of the hydraulic hose connection cap 10 of the present invention.
0 consists of a base body 12 and an oil pipe 14. This hydraulic hose connection cap 10 connects hoses 16 to each other as shown in FIG.
口金本体１２は、その両側に油圧ホース締結部
１８を備えており、両締結部１８の間には半径方
向内方に延びている仕切り部２０を備えている。
仕切り部２０には、両側の油圧ホース締結部１８
を互に連通している貫通孔２２が形成されてい

る。 The base body 12 is provided with hydraulic hose fastening parts 18 on both sides thereof, and is provided with a partition part 20 extending radially inward between the two fastening parts 18.
The partition part 20 has hydraulic hose fastening parts 18 on both sides.
A through hole 22 is formed which communicates with each other, and an oil pipe 14 is inserted through the through hole 22.
貫通孔２２の内径d1は油管１４の外径d2よりも
大きく形成されていて、油管１４が貫通孔２２で
半径方向に移動できるように挿通されている。d1

は金属又はプラスチツク等で作ることができる。 The oil pipe 14 is supported with respect to the base body 12 by an elastic plate 24 as shown in FIG. That is, the elastic plate 24 is formed with a hole 26 having a diameter d 3 somewhat smaller than the outer diameter d 2 of the oil pipe 14, and slits 28 are provided around the hole 26 at appropriate intervals. Therefore, the oil pipe 14 is supported by the mouthpiece body by passing the elastic plate 24 through the oil pipe 14 from the sides of both hydraulic hose fastening parts 18 and pressing it against the partition part 20 of the mouthpiece body 12. . elastic plate 24
can be made of metal or plastic.

なく、この部分に傷が付くことによる亀裂の発生
も防止できる。 Since the hydraulic hose connection cap 10 of the present invention is constructed as described above, when the hydraulic hose 16 is inserted into the oil pipe 14 as shown in FIG.
The oil pipe 14 can freely move in the radial direction to a position where the central axis of the hydraulic hose 16 is aligned with the central axis of the hydraulic hose 16.
Therefore, when the hydraulic hose 16 is fixed by caulking the part indicated by number 30 in FIG.
6 is caulked with a uniform force without being eccentric with respect to the base body 12 and the oil pipe 14, there is no danger that the inner peripheral wall surface of the through hole 32 of the hydraulic hose 16 will be deeply bitten by the outer peripheral corner 34 of the end face of the oil pipe 14. This also prevents cracks from occurring due to scratches in this area.

４′により深く食い込んで、この部分から亀裂が
生じる欠陥が生じた。 On the other hand, as shown in FIG. 4, in the conventional hydraulic hose connection cap 10', the cap body 12' and the oil pipe 14' are fixed by brazing.
If the machining accuracy when drilling the through hole 22' is low, the oil pipe 1
4' is eccentrically fixed to the base body 12'. Therefore, the inner circumferential wall surface of the through hole 32' of the hydraulic hose 16' is aligned with the outer circumferential corner portion 3 of the end surface of the oil pipe 14'.
A defect occurred that penetrated deeper into 4' and cracked from this part.

メツキ処理を施すことができる。 Further, according to the hydraulic hose connection cap 10 of the present invention, a uniform caulking pressure is applied to the outer peripheral surface of the oil pipe 14, so that oil leakage and collapse of the oil pipe 14 can be prevented. In addition, since no brazing is required, the cap body 1, which has been a problem in the past.
2 and the oil pipe 14 due to material change due to heat,
Can prevent strength loss. Furthermore, since the plating solution for rust prevention can sufficiently circulate through the gap between the through hole 22 and the oil pipe 14, complete plating can be performed.
