【考案の詳細な説明】 〔考案の属する技術分野〕 本考案は油圧シリンダ用継手に関する。[Detailed explanation of the idea] [Technical field to which the invention belongs] The present invention relates to a joint for a hydraulic cylinder.

継手を取付け継手と油圧シリンダのフランジとの
間は通常距離が短いためゴムホースの使用は不可
能であり鋼管を使用していた。 Rubber hoses are generally used for piping to moving hydraulic cylinders, and when the hydraulic pressure of the hydraulic cylinder is high, the rubber hoses become thick and quite hard, so they are connected to the hydraulic power source or switching valve with a large arc. . For this reason, when the rubber hose is directly connected to the hydraulic cylinder, this arc requires a large space in the axial direction of the hydraulic cylinder, resulting in wasted area. Therefore, the joint is mounted in the middle of the hydraulic cylinder, and since the distance between the joint and the flange of the hydraulic cylinder is usually short, it is impossible to use a rubber hose, so a steel pipe is used.

Here, an example of a conventional hydraulic cylinder joint is shown in the second example.
This will be explained with reference to the figure and FIG. A hydraulic cylinder 12 is fixed to the side surface of a movable body 11 that is moved left and right in the figure by a drive mechanism (not shown), and from a joint 13 installed in the middle of the hydraulic cylinder 12, steel pipes 14 and 15 connected thereto and a pipe joint 16 are connected. The piping is connected to the head end flange 17 and the rod end flange 18 via rubber hoses 21 and 22 from a switching valve 20 mounted on a base 19 to the joint 13. Note 12
A is the piston rod.
このような形式では油圧シリンダの作動時に鋼
管１４或いは１５のいづれか一側に高圧が作用し
例えば鋼管１４は両端が固定のため伸びによる剪
断力を受けて破損することがあつた。 In such a type, high pressure is applied to one side of the steel pipe 14 or 15 when the hydraulic cylinder is operated, and for example, since both ends of the steel pipe 14 are fixed, the steel pipe 14 may be damaged by shearing force due to elongation.

The present invention eliminates these drawbacks, and its purpose is to provide an elastic joint for a hydraulic cylinder in which the steel pipe connecting the hydraulic cylinder and the joint will not be damaged no matter how high the pressure is applied.

The elastic joint for a hydraulic cylinder of the present invention is installed in the middle of a hydraulic cylinder in order to connect a steel pipe to a head end flange and a rod end flange of the hydraulic cylinder, and is attached to the shaft of the hydraulic cylinder in order to divide the connecting portion of each steel pipe into two. It is characterized by having slits in the right angle direction to absorb the elongation of the steel pipe through elastic deformation.

The present invention will be explained in detail below with reference to FIG. 1, which shows an embodiment of the present invention. In the figure, a hydraulic cylinder 12, a piston rod 12A, steel pipes 14 and 15, a pipe joint 16,
Head side flange 17・Rod side flange 18・
Base 19, switching valve 20, rubber hoses 21 and 22
is the same as the conventional example shown in FIGS. 2 and 3, so a detailed explanation will be omitted and a different elastic joint 31 will be explained. The elastic joint 31 is constructed by providing a slit 34 parallel to both passages 32 and 33 in the middle of a passage 32 connecting the steel pipe 14 and the rubber hose 21 and a passage 33 connecting the steel pipe 15 and the rubber hose 22. More than half are divided into two. Therefore, when the hydraulic cylinder 12 is operated, high pressure is applied to either side of the steel pipe 14 or 15. For example, when the steel pipe 14 is extended, the elastic joint 31, which fixes the left end of the steel pipe 14, bends to the left due to the slit 34, which causes shearing force. I never receive it.

As explained above, the elastic joint for a hydraulic cylinder of the present invention has a slit that divides the head end flange and the rod end flange into two at the connecting portion of the steel pipe that connects the two. As a result, when the hydraulic cylinder is operated, the elastic joint bends in response to the extension force of the steel pipe, and the steel pipe easily extends in the axial direction, so no shearing force is generated. Therefore, there is no possibility of damage to the steel pipe, which has the advantage of extending the life of the steel pipe and increasing the reliability of the machine equipped with this hydraulic cylinder.
