Description

[Detailed description of the invention] The present invention configures a flow path for a liquid or gaseous fluid by connecting a hose to an opening of a container body or connecting the openings with a hose in a watertight or airtight manner. Related to connectors for

Conventionally, for example, several connectors were integrally protruded from the cooling part of a synthetic resin mold, and one end of a hose was inserted into the connector. When removed from the molding machine and placed on the ground, the protruding connector may get in the way or be damaged, which is inconvenient and disadvantageous.

The main purpose of the present invention is to provide a connector that can eliminate the above-mentioned inconveniences and drawbacks, but it also has the purpose of providing a connector that can be used to connect a hose to an opening of a container body other than the mold, or to connect a hose between the openings. It should also be understood that the purpose is to provide a coupling for use in coupling.

The present invention will be explained based on the illustrated embodiments as follows.

As shown in FIGS. 1 to 3, the connector 1 of the present invention mainly includes a connecting pipe 2, a cylindrical tightening member 3, an elastic sealing member 4, and a spring washer 5.
The connecting tube 2 has a collar portion 6 near the base end, a connecting portion 8 for the hose 7 on the outside thereof, a threaded portion 9 on the outer periphery of the center, and a groove 10 on the outer periphery of the distal end. Tightening member 3
has a cylindrical shape and has a threaded portion 11 therein, through which it is screwed into the threaded portion 9 of the connecting pipe 2.
The elastic sealing member 4 has a ring shape and is fitted around the outer periphery of the connecting tube 2 near its tip. The spring washer 5 is fitted onto the outer periphery of the connecting pipe 2 between the tightening member 3 and the sealing member 4. Furthermore, the inner and outer connecting pipes 2 of the sealing member 4
Annular clamping pieces 12 and 13 are fitted on the outer periphery of the connecting pipe 2, and a C-shaped stopper piece 14 is fitted on the groove 10 on the outer periphery of the tip of the connecting pipe 2.
are fitted.

As shown by the solid line in FIG. 4A, the spring washer 5 has a substantially V-shaped cross-section bent about the center line a, and when this state is viewed from the direction of the arrow, which is the facing direction, the outline shape is are formed to form concentric circles, but in an unbent flat state or bent at a large angle (larger than the angle shown by the solid line) around the center line a as shown by the chain line in Figure 4A. In this state, the outline shape is an ellipse when viewed from the facing direction, as shown by the chain line in FIG. 4B. Before the spring washer 5 is untightened by the fastening member 3, which will be described later, the spring washer 5 is provided so that its outline becomes concentric circles as shown by the solid line in FIG. 4B when viewed from the facing direction.

In the connector 1 having such a configuration,
As shown in FIG. 2, the tip of the connector 1 is inserted into the opening 15 of the fluid path of a container such as a cooling section of a synthetic resin mold, and the tightening member 3 is rotated forward to release the spring at the tip. When the washer 5 is pressed, the sealing member 4 is thereby clamped between the clamping pressure pieces 12 and 13 as shown in FIG. As the bending angle of the spring washer 5 becomes smaller, its outline becomes an ellipse as described in connection with FIG. Therefore, the connector 1 can be fixed in the opening 15 in a watertight and airtight manner. When the tightening member 3 is rotated backward to release the tightening, the sealing member 4 and the spring washer 5 return to their original states, and the connector 1
can be removed from the opening 15.

As is clear from the above, the maximum deformation diameter of the sealing member 4 and the spring washer 5 should be designed to a size that allows sufficient pressure to be applied to the inner wall of the opening 15 of the vessel in which the connector 1 is to be used. Needless to say.

Since the present invention is configured as described above, a hose is removably connected to the opening of the vessel to which liquid or gas is to be supplied, or between the openings, thereby configuring a flow path for the fluid. It is extremely useful in practical use as a connector for

Claims (1)

[Scope of utility model registration request] The cylindrical clamping member includes a connecting pipe having a hose connecting part at one end, a cylindrical clamping member, an elastic sealing member, and a spring washer bent into a substantially V-shaped cross section, and the cylindrical clamping member is attached to the central outer periphery of the connecting pipe. The attachment member is screwed together so as to be movable forward and backward in the axial direction, and the sealing member is fitted onto the outer periphery of the distal end of the connecting pipe so as not to come off from the distal end, and the connection between the tightening member and the sealing member is established. The spring washer is fitted onto the outer periphery of the tube, and the spring washer is formed so that when pressed by the tightening member, the bending angle becomes large and at least both opposing ends of the spring washer protrude in the radial direction. Connecting device.
