[0002]
[Prior art]
This kind of conventionally known pipe switching by arbitrarily switching the movable side piping ports with nut members provided at both ends of the U-shaped pipe to the fixed side piping ports with male threads provided at the fixing portion. In the manual line switching device of the type that performs the above, a tool such as a spanner is directly applied to the nut member, and this is turned off and tightened. For this reason, when installed in a narrow space, tools such as a spanner are difficult to turn, and the tool may be removed, the switching operation may take time, or other parts may be damaged. In order to avoid these disadvantages, it is often used to install with a large space, and it cannot be said that it is fully compatible with space saving and miniaturization. Met.

【Example】
In the embodiment shown in the figure, the movable side piping ports 4 and 5 are provided at both ends with respect to the fixed side piping ports 2 and 3 provided at the central point of the fixed plate 1 and the circular line centering on the central point. The present invention relates to a pipe switching device of a type in which pipes are switched by arbitrarily switching the U-shaped pipe 6 having the male screw 8 provided on the outer peripheral surface of the rim of the fixed side pipe ports 2 and 3. And the nut members 9 and 10 attached to the edges of the movable side piping ports 4 and 5 so as to be freely rotatable and unremovable. Are formed on the same surface to form large-diameter gears 11 and 12, and support shafts 13 and 14 are erected at positions near both ends of the outer curved surface of the U-shaped tube 6, and short at the tips of the support shafts 13 and 14. Square arm shafts 15 and 16 for arm attachment / detachment are provided, and separately from this, the large-diameter gears 11, 1 are provided at the lower end. The shaft rod 18 is provided with a small-diameter gear 19 that can be meshed with the shaft rod 18. The arm member 22 is supported so as to be unremovable and rotatable, and is provided with a connecting square hole 24 that can be fitted to the arm attaching / detaching angular shafts 15 and 16 at the distal end portion of the arm member 22. The small-diameter gear 19 engages with the large-diameter gears 11 and 12 when engaged with the gears 15 and 16, and the upper end of the shaft rod 18 projects above the arm member 22 so that the projecting portion is a hexagonal wrench or the like. The angle axis 25 is used for tooling.
[0006]
In the figure, reference numeral 27 denotes a proximity switch that reacts to the tip position of a rod 28 erected on the inner curved surface of the U-shaped tube 6, and 29 denotes an arm member in which the upper end portions 30 of the support shafts 13 and 14 are rotatably fitted. A bearing hole 31 for smoothing the rotational movement along one horizontal plane 22 indicates a seal.
[0007]
When the U-shaped tube 6 is replaced in the above embodiment, it is necessary to remove the nut members 9 and 10 from the male screw 8 or to connect them again. At this time, the support shaft corresponding to the one to be removed. The small-diameter gear 19 and the large-diameter gear are fitted by fitting the arm attaching / detaching angular shaft 15 provided at the upper end of the arm 13, the square hole 24 provided at the tip of the arm member 22, and the upper end portion 30 of the support shaft 13 and the bearing hole 29. 11 is engaged, and in this engaged state, a spanner (not shown) is hung on the tool hooking angular shaft 25 to rotate the shaft rod 18, that is, the small-diameter gear 19, and the large-diameter gear 11, that is, the nut member is rotated by the rotation of the small-diameter gear 19. When the nut member 9 is removed by turning 9, and the nut member 9 is screwed to a place where it can be turned manually, the small diameter gear 19 and the large diameter gear 11 are engaged with each other in the same manner as in the case of the above removal. On purpose, it is to use in usage, such as tightening the nut member 9 carried out in the reverse turning of the turning operation by the spanner in the meshed state.
[0009]
【The invention's effect】
Since the manual pipeline switching device according to the present invention is as described above, the nut member is attached and detached, that is, the movable side piping port is connected to the fixed side piping port by turning the outer end of the shaft rod of the small diameter gear with a tool such as a spanner. It can be removed or reconnected, and in the case of U-shaped pipe replacement work, it is not necessary to hang a tool such as a spanner directly on the nut member that is located in a narrow space, and it exists in an open space. The same work can be performed by putting a tool such as a spanner on the outer end of the shaft rod, and the above inconveniences in use and the insufficiency for space saving and miniaturization can be solved. .
