[Means for solving problems]
In order to achieve the above object, in the invention according to claim 1 of the present invention, a receiving plate and a pressing plate are integrally formed via a curved portion, a support plate is erected on the receiving plate, and the receiving plate and the receiving plate are provided. A tube pressing means for sandwiching the tube is provided at a portion where the pressing plates face each other, and the pressing plate is supported by the support plate in a detachable manner. Further, as in the invention of claim 2, the support plate and the curved portion are each provided with a tube through hole into which the tube is loosely inserted, and the receiving plate and the pressing plate are mutually provided between the support plate and the curved portion. The tube pressing means may be provided at a portion facing the tube.

Further, in the clip of the present invention, as in the invention of claim 3, the entire clip is integrally molded with a rigid material such as a rigid resin material, and a thin portion is provided in the curved portion across the tube through hole of the curved portion. It is preferable that the thin-walled portion is provided with a habit of opening the push plate in the opening direction.

With this configuration, when the locking relationship of the push plate with respect to the support plate is released to release the pinching pressure of the tube, the restoring elasticity of the tube and the push plate applied to the thin portion of the curved portion of the clip are released. The opening direction opening and expanding habits act synergistically, and the push plate is instantly opened to the opening position without resistance and resumes the flow of fluid in the tube.

Further, since the clip of the present invention is used in a state of being attached to the tube, as in the invention of claim 4, the tube through hole and the curved portion of the support plate are in the state where the push plate is in the open position. It is preferable that the tube is loosely inserted into the tube through hole of the above, and the tube is elastically brought into contact with both the through holes and the tip of the protrusion on the receiving plate side so that the tube surface can be frictionally moved.

With this configuration, the mounting position with respect to the tube, that is, the pinching position of the tube can be set in advance, so that the action and effect of the invention according to claim 1 can be made more effective from the handling aspect.

The tube pinching by the clip of the present invention is performed by inserting the tube into the tube through hole of the support plate and the tube through hole of the curved portion and is performed between the two through holes, so that the tube is not misaligned. As the pressing means, it is possible to apply a holding protrusion shape similar to a clip having a well-known structure in which one place is pressed from above and below in opposition to each other. However, as in the invention of claim 5, the tube pressing means is received. It is preferably composed of two protrusions provided on the plate close to each other in the direction across the tube, and protrusions provided on the push plate corresponding to the two protrusions and with the tip facing between the two protrusions.

With this configuration, the pinching pressure of the tube is performed in such a manner that one protrusion is pushed from the opposite side between the two front and rear protrusions, and the tube is bent in a dogleg shape and sandwiched in a flat shape in a lateral view. It is pressed and the upper and lower inner surfaces of the tube are airtightly crimped.

Therefore, the pinching pressure is dispersed in the longitudinal direction of the tube and the inner surface of the tube of the pinching portion is joined by bending, as compared with the conventional presser foot type in which the pinching pressure is concentrated on one place from the top and bottom facing each other. Since the area is expanded, the pressure load applied to the tube itself can be reduced. Further, since the dogleg-shaped bending of the tube due to the pinching pressure of the tube occurs only in the portion inserted into the tube through hole of the support plate and the tube through hole of the curved portion, that is, inside the tube, the pinching portion of the tube The effect of bending does not affect the tube outside the clip, and the straightness of the tube before and after the clip is kept almost constant regardless of the pinching pressure and opening of the tube.

In order to lock the end of the push plate to the support plate and support the push plate in the closed position, as in the invention of claim 6, the end of the push plate corresponds to the support plate and the upper half of the support plate. A step for loosely inserting a support hole, providing a locking claw for engaging and disengaging with the support hole edge on the front surface of the upper half of the support plate, and restricting the closing position of the push plate at the base of the upper half of the support plate. It is preferable that the structure is provided with a portion.

With this configuration, when the end of the push plate is pressed in the closing direction, the upper half of the support plate enters the support hole from the middle of closing the push plate, and the support plate elastically bends backward and the locking claws. Passes through the support hole and the locking claw locks to the support hole edge on the push plate. Further, at this point, the push plate comes into contact with the steps on both sides of the support plate, and the push plate is supported at the closed position. In this way, since the end portion of the push plate is connected to the receiving plate via the support plate, the push plate does not laterally shift with respect to the receiving plate, and the closed position is stable.

Further, when using the clip of the present invention to press the end of the push plate in the closing direction to prevent the flow of the fluid in the tube, the end of the receiving plate and the end of the push plate are pinched with the fingertips of two fingers. When opening the push plate by releasing the locking relationship between the end of the push plate and the support plate and releasing the tube from the pinching pressure to allow the fluid to flow in the tube, the upper half of the support plate It is operated by pinching the end and the end of the push plate with the fingertips of two fingers. Therefore, as in the invention of claim 7, a knob portion is formed on each of the upper half portion of the support plate, the end portion of the push plate, and the end portion of the receiving plate, and the knob portion of the upper half portion of the support plate is the upper half portion of the support plate. It is preferable that the end portion of the push plate is bent in a forward-tilting shape, and the grip portion of the push plate end portion is configured such that the push plate end portion is inclined upward from the support hole to the push plate end.

With this configuration, in the operation of pressing the end of the push plate in the closing direction, the fingertips of two fingers are hung on the end of the push plate and the end of the receiving plate to perform a picking operation. Since the fingertip, for example, the fingertip of the index finger, is hung on the upper surface of the push plate end portion that is inclined diagonally upward beyond the push plate end, the operation becomes easier. Further, in the operation of releasing the locking relationship of the push plate with respect to the support plate, the fingertips of the two fingers are hung on the end of the upper half of the support plate and the end of the push plate to perform a picking operation. The fingertip of the finger, for example, the fingertip of the thumb is hung on the end of the push plate on the tube, and the fingertip of the other finger, for example, the fingertip of the index finger is hung on the end of the upper half of the support plate bent in a forward tilting shape. Therefore, it becomes easy to operate.

Further, in the state where the push plate is in the open position, the push plate end portion is separated above the end portion of the support plate upper half portion, but the end portion of the support plate upper half portion is supported by the push plate end portion. When the end of the push plate is pressed in the closing direction by facing the rotation locus of the hole, the outer surface of the end of the upper half of the support plate bent in a forward-tilting shape supports the upper half of the support plate. It functions as a guide surface to be inserted into the hole, and the upper half of the support plate can be reliably inserted into the support hole.
