Then, the central member 40 is pressed into the upper member 30 from above and below and the lower member 50 formed at the bottom of the box body to constitute the bottom inner box 20. The consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs printed the frame 3 of the upper member 3 1 and the protruding piece 3 2 on the bottom surface was pressed into the cover of the central member 40 to become the cover of the outlet 43 and the frame of the lower member 5 was borrowed. The protruding piece 5 2 of the top surface 5 is pressed into the recessed portion 45 provided in the nozzle forming body 44 of the central member 40, and the lower member 50 becomes the bottom of the bottom inner box 20. [Example] Figure 6 shows the upper member 30 changed to a direction different from that shown in Figure 5. The paper size applies the Chinese National Standard (CNS) A4 specification (210X 297 mm) -5- 546470 A7 B7 5.

Below 0. FIG. 10 is a perspective view showing the central member 40 in the same direction as the upper member 30 shown in FIG. 6, FIG. 11 is a top view of FIG. 10 viewed from the D direction, and FIG. 12 is a view of FIG. 10. A bottom view viewed from the R direction, FIG. 13 is a cross-sectional view taken along the line A-A in FIG. 11, FIG. 14 is a cross-sectional view taken along the line 6-: 6 in FIG. 11, and FIG. 15 is a cross-sectional view taken in FIG. 12-10. 4 2 is an inflow nozzle, 4 3 is a discharge port, 4 4 is a formed body forming the inflow nozzle, 4 5 is a recess provided in the formed body, 4 6 is a pin insertion portion, 47 is a wall portion around the discharge port 43, 48 It is a recessed part provided in the wall part 47. The consumer cooperation of the Intellectual Property Bureau of the Ministry of Economic Affairs of the People's Republic of China Du printed the central member 4 0 shown in Figure 11 above the contact with the upper member 3 on the right side of Figure 8 ◦ Below, the protruding piece 3 2 of the upper member 3 0 was pressed into Figure 1 1 The recessed part 48 above the central member 40 is shown so that the upper member 30 and the central member 40 are combined with each other. FIG. 16 is a perspective view of the lower member 50, FIG. 17 is a top view thereof, and FIG. 18 is a cross-sectional view taken along B-B in FIG. 17, where 51 is a frame, 5 2 is a protruding piece, 5 3 is a latch, and 5 4 is a frame Individual display of 5 1 ribs. The upper part of the lower part 50 is opposite to the lower part of the central part 40 shown in FIG. 12. By pressing the protruding piece 5 2 into the recessed part 4 5 of the central part 40, the paper size applies the Chinese National Standard (CNS) A4 specification. (210X297 mm) -6- 546470 A7 B7 V. Description of the invention (4) Press the pin 5 3 into the pin insertion portion 46 of the central member 40, and connect the lower member 50 to the central member 40. (Please read the precautions on the back before filling this page.) The lower member 50 can be formed as the bottom of the bottom inner box 2 0. At the same time, the ribs 5 4 are implemented to promote the self-inflow nozzle 4 2 to enter the bottom inner box 2 0. The ground impinges on the impeller, causing the water to form a turbulent bottom flow resistance. The latch 5 3 adopts a method that can adjust the flow resistance at the bottom to determine the position when the lower member 50 is coupled to the central member 40. As shown in FIGS. 7 and 9, holes 4 9 are attached to the upper member 30. When the bottom inner box 20 is installed on the top inner box 3, it is snapped on the convex portion provided on the top inner box 3. Positioning both. This allows the watch to be assembled in exactly the same direction when assembling the watch. For the bottom flow resistance caused by the ribs 54 of the lower member 50, ribs are provided under the top inner box 3 to form the top flow resistance. In the above description, although the embodiment in which the bottom inner box is divided into three has been described, the present invention is not limited to this. The number of divisions or the position of the central member can be arbitrarily set, and any method such as welding or joining can be adopted in combination Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs [Effect of the invention] The double-box water meter of the present invention is structured as described above. Precisely processed with good accuracy, eliminating the unevenness of measurement accuracy. When manufacturing the divided components, a plurality of molds can be formed at a time, enabling extremely efficient manufacturing. And it can be decomposed. Therefore, the size of the paper g ^ paper is applicable to the Chinese National Standard (CNS) A4 specification (21〇 > < 297 mm) 546470 A7 _ B7_ V.
