を行う。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. The present embodiment is a hose mounting device for a suction hose used in a vacuum cleaner, to which an accessory such as an extension pipe having a suction port can be mounted. 1 to 3, a flexible hose 1 having a helical protrusion 2 on its outer periphery is provided with four cylindrical protrusions 4, 5, 6, which engage with the protrusion 1 of the hose 1. 7 and a packing member 8
Packing fixing member 9 for fixing the
Is positioned on the outer periphery of the packing member 8, and the claw portion 10 provided integrally with the packing locking member 9 is connected to the locking holes 11 (a) and 11 (b) provided in the hose locking member 3 to connect the hose joint. 12, and the hose joint 12 is provided with two locking holes 13.
Is attached to the hose joint 12 by locking a tubular hose stopper 15 provided with the same. With these configurations, in this embodiment, when a pulling force is applied to the hose 1, the hose locking member 3 comes into contact with the hose stopper 15 attached to the hose joint 12. Since it acts as a locking portion between the hose 1 and the hose joint 12, it does not easily come off. Further, the connection between the hose 1 and the hose joint 12 is not fixed by bonding or screws, but is held rotatably by a combination of a tubular hose locking member 3 and a hose stopper 15. Therefore, even if a force in the direction in which the hose 1 is twisted is applied during use, according to the present embodiment, the hose 1 does not come off because the hose locking member 3 locked to the hose 1 rotates. Further, the hose locking member 3 is integrally formed with a cylindrical projection 16 fitted to the inner wall of the hose 1 and a wall 17 with which the end face of the hose 1 is in contact. The cylindrical projection 16 prevents the hose 1 from bending. When a tensile force is applied to the hose 1, the projection 2 has the projection 2 and the projections 4, 5, 6, 3 of the hose locking member 3. 7 does not come off. Further, by inserting the end surface of the hose 1 until it comes into contact with the wall 17, the mounting position of the hose 1 can be clarified, and the hose mounting failure during the assembly operation can be prevented. Further, since the packing member 8 is fixed between the hose locking member 3 and the packing locking member 9, it can be prevented from shifting in the front-rear direction and can always maintain a constant airtightness. In addition, since the portion in contact with the hose joint 12 is the contact portion 18 provided integrally with the packing member 8, the frictional force with the hose joint 12 can be reduced, the rotation is smooth, and the leak is reliably prevented. Here, the work of attaching the hose 1 and the hose locking member 3 will be described. The spiral of the projection 2 of the hose 1 and the projections 4, 5, 6, and 7 are provided at the same pitch on the hose locking member. The hose locking member 3 is screwed and mounted.

た構成となっている。Further, the hose 1 is formed continuously by extrusion and can be mounted in the same manner even if any part is cut. Therefore, even if the hose is slightly damaged, the hose 1 can be cut and arbitrarily mounted. It is possible. When removing the hose 1 and the hose locking member 3, the hose 1 and the hose locking member 3 can be easily removed by twisting the hose 1 in the opposite direction to the mounting. Further, the packing member 8 is integrally formed with a projection 19 so as to rotate simultaneously with the hose locking member 3, and the projection 19 is structured to be sandwiched between the grooves 20 formed in the packing locking member. It surely rotates in conjunction with the hose 1. FIG. 4 shows a state in which a vacuum cleaner is used, and a hose joint 1 is shown.
2, an extension pipe 20, a suction port 21, and a cleaner body 22 are connected.
