However, the conventional hose joint as described above has the following problems. That is, in order to screw and connect the receiving device and the wearing device,
The hose fitting must be rotated 4-5 times. This is too inconvenient to connect and disconnect the joints, which is inconvenient when it is necessary to frequently attach and detach.

The present invention solves the above problems and provides a hose joint for an intake / exhaust port of an intake / exhaust tank in which a hose joint provided in the intake / exhaust port of an intake / exhaust tank mounted on a suction wheel or the like can be quickly attached and detached. The purpose is to do.

[0005]

Means of the present invention taken to solve the above problems are as follows. A hose joint for an intake / exhaust port of an intake / exhaust tank mounted on a suction vehicle, the hose joint including a receiver attached to the inlet / outlet side and a fitting attached to the hose side. The tool is provided with a fixing means and has a seat plate having a liquid passage hole, a connecting pipe provided on the outer periphery of the liquid passage hole of the seat plate, and an engaging member provided so as to project on an inner wall portion of the connecting pipe. The mounting device is provided with a connecting means for connecting a hose, a fitting pipe that can be fitted into the connecting pipe of the receiving device with substantially no gap, and a wall part of the fitting pipe. And an engaging groove engageable with the engaging member of the connecting pipe and bent from the opening of the insertion pipe in a longitudinal direction to a circumferential direction at a substantially right angle. It is a hose joint for intake and exhaust of the intake and exhaust tank.

(Operation) When connecting the fitting of the hose joint and the fitting, the fitting pipe of the fitting is fitted into the connecting pipe of the fitting, and the engaging groove inlet provided in the fitting mouth of the fitting pipe. Is further pushed according to the engaging member of the connecting pipe, and the mounting tool is rotated in a desired direction so that the engaging member engages with the circumferential groove of the engaging groove. In this way, it is not necessary to rotate the wearing tool many times when connecting, and quick work is possible. Further, when removing the receiving tool and the wearing tool, the procedure may be generally reversed from the above procedure.

1, a connecting pipe 13 having a slightly larger diameter is provided, so that a hose 3 to be described later is provided at the inner base of the connecting pipe 13.
Is provided with a step portion 14 for abutting the tip end portion thereof. On the inner surface of the front edge portion of the connecting pipe 13, there is provided a tapered portion 15 having a widened front end side. The taper portion 15 is provided for facilitating the fitting of the fitting pipe 20 of the mounting tool 2 described later. A screw hole 16 is formed in the connecting pipe 13 by penetrating the wall portion.
Is provided. A wing screw 17, which is a tightening screw, is screwed into the screw hole 16. In addition, on the inner surface of the connecting pipe 13,
Engaging pin 18 which is an engaging member protruding in the diameter direction of the pipe
Are provided in two places facing each other.

Please refer to FIG. 4 and FIG. Reference numeral 2 is a wearing tool, which is not shown in FIG. The fitting 2 is a fitting tube 20.
It has. The outer diameter of the fitting pipe 20 is formed to be slightly smaller than the inner diameter of the connecting pipe 13. Handlebars 22 are provided at two locations on the outer peripheral surface of the fitting pipe 20 so as to project outward in the diametrical direction. Engagement grooves 21 corresponding to the engagement pins 18 are provided at two locations on the fitting-side tube mouth wall portion of the fitting tube 20.
