B The suction tube A mentioned above is a right circular tube formed in a double structure consisting of an outer tube 2 and an inner tube 1 that slides inside the outer tube 2. The outside of the tip of outer tube 2 is connected to outer tube 2 and T.
The connecting shaft 21 is formed into a letter shape, and the inner side is a hollow right circular tube with a step 12 formed due to the difference in inner diameter, and the inner tube 1 and outer tube 2 are fixed to the rear end. The rotary joint 22 is provided with a fastening portion 25 that is connected to the connecting shaft 21, and a rotary joint 22 in which outer tubes obtained by dividing the portion near the connecting shaft 21 into two are fitted together and slide around the circumference of the outer tube. The total length of the inner tube 1 is longer than the outer tube 2, and a step 12 is formed on the outside due to the difference in outer diameter.
When the inner tube 1 is drawn into the outer tube 2, the respective steps 12 abut each other to prevent the inner tube 1 from entering too much, and the inner tube 1 is stored at a predetermined position within the outer tube 2. Further, each outer diameter of the inner tube 1 is made somewhat smaller in diameter than each inner diameter of the outer tube 2, so that the inner tube 1 can slide inside the outer tube 2. (b) A split bearing portion 2B is formed on the back surface of the suction port body B to receive the connecting shaft 21 of the suction pipe body A. The upper bearing B4 supports the variable angle θ of the suction pipe body A.
An elongated hole or a groove-shaped opening that can be tilted within the range is opened to form the through-hole of the suction pipe body A.
Further, since the inner tube 1 extends within the range of the variable angle θ, an oval or rectangular opening B1 is provided on the suction surface side. (2) The scope of the utility model registration claim, in which the connecting shaft 21 of the outer tube 2 is spherical, the bearing surface of the bearing portion B2 of the suction port B is also a bearing that matches the spherical shape of the connecting shaft 21, and the rotary joint 22 is omitted. A suction pipe and a suction port for a suction vacuum cleaner according to item 1. (3) Attach the lid B6 to the suction surface side opening B1 of the suction port body B.
A suction pipe and a suction port for a suction vacuum cleaner according to claim 1 of the registered utility model claim. The brief description of the drawing has been amended as follows. Next to the 13th line on page 8 of the specification, it says, ``Figure 15 is an assembled side view (cross-sectional view) of the suction port body with a lid.
Figure 6 is a partial cross-sectional view of the ZZ^ portion of Figure 17 (detailed view of the lid). FIG. 17 is a partial bottom view of FIG. 15. 1st

Claims

[Claims for Utility Model Registration] (1) A suction pipe and suction port for a suction vacuum cleaner, characterized by comprising a suction pipe body A and a suction port body B that meet the following conditions. B In the above, the suction tube body A includes the outer tube 2 and the outer tube 2.
It is a right circular tube formed in a double structure consisting of an inner tube 1 that slides inside. The outer side of the tip of the outer tube 2 is a connecting shaft 21 formed in a T-shape with the outer tube 2.
Further, the inner side is a hollow right circular tube with a step 12 formed due to the difference in inner diameter, and the rear end is provided with a fastening part 25 for fixing the inner tube 1 and the outer tube 2, and furthermore, the part near the connecting shaft 21 is made of two. It consists of a rotary joint 22 that fits each divided outer tube and slides on its circumference. The total length of the inner tube 1 is longer than the outer tube 2, and a step 12 is formed on the outside due to the difference in outer diameter. It stops the passing,
The inner tube 1 is housed in a predetermined position within the outer tube 2. Further, each outer diameter of the inner tube 1 is made somewhat smaller in diameter than each inner diameter of the outer tube 2, so that the inner tube 1 can slide inside the outer tube 2. (b) A split bearing part B2 is formed on the back surface of the suction port body B to receive the connecting shaft 21 of the suction pipe body A. The upper bearing B4 has a variable angle of 0 for the suction pipe body A.
The through hole of the suction pipe body A is formed by hollowing out an ellipse that can be tilted within the range of . Further, since the inner tube 1 extends within the range of variable angle 0 on the suction surface side, an oval or rectangular opening B1 is provided. (2) The connecting shaft 21 of the outer tube 2 is made spherical, and the bearing surface of the bearing part B2 of the suction port B is also a bearing that matches the spherical shape of the connecting shaft 21, and the rotary joint 22 is omitted and a fitting joint using a tapered pipe is used. A suction pipe and a suction port for a suction vacuum cleaner according to claim 1 of the registered utility model claim.
