In other words, the pointer of the water meter becomes cloudy, making it difficult to read the meter smoothly. B○ The upper case comes off more easily than the lower case. C: Because the lower case is fixed to the heat insulation pipe, it is not possible to lower the lower case, and it takes time to repair water leaks in the piping.

The above-ground water meter box of the present invention was developed to solve the above problems.

That is, the gist of the present invention is to provide a lower case, an upper case, two heat insulating tubes to be fitted into the lower opening of the lower case, a fixing plate for fitting and fixing the lower end of the heat insulating tubes, and the fixing plate. It consists of a stopper, a heat insulating material, and a convex lens, and a meter reading window and a water stop valve window are opened on the upper surface of the upper case, respectively, and one end of the water stopper window is connected to the upper case with a connecting cord. A fixed cap is fitted into the upper case, and locking protrusions are attached to the lower ends of both sides of the upper case, while a locking groove is formed at the upper edge of the lower case. A cylindrical opening for fitting and locking the above-mentioned heat insulating tube is provided on both sides of the bottom, and the upper edge of the opening is provided with a
An appropriate number of locking arms with open upper ends are formed,
A heat insulating material is loaded into the space between the upper case and the lower case, and the flat part of the convex lens is brought into close contact with the pointer window glass plate of the water meter disposed inside the case. After inserting the locking protrusion into the locking groove of the lower case, screw the fixing screw into the small hole of the locking protrusion, and engage the screw by abutting the tip of the screw against the sloped side wall of the locking groove of the lower case. Press the locking protrusion into contact with the outer wall of the locking groove, and furthermore, fit and fix the heat insulating pipe inserted into the lower case with a fixing plate, and tighten the fixing plate above the rising water pipe with the above stopper.

0 and 11 are fixed, metal arms 9 are passed through the pedestal 11 to be suspended and locked on both sides of the water meter 24, and the arms 9 are attached to the water meter 24.
By hanging on both sides of the water meter 24, the lower case 2 is held on the pipe to which the water meter 24 is attached. Further, numeral 34 in the figure is a cylindrical opening into which the heat-retaining tube 12 is inserted, and a locking portion 35 is provided at the upper end. The locking portion 35 is formed in the shape of a free piece (not shown) with a constant width, and the base is fixed. Therefore, when lowering the lower case 2 along the heat-retaining tube 12, the locking portion 35 is moved outward. If it is pushed open, the heat-retaining tube 12 can protrude upward. Therefore, if water leaks from the water stop valve 23, the above-mentioned arm 9
is removed from the water meter 24, the fixing screw 36 is removed from the locking protrusion 7, the upper case 1 is removed from the lower case 2 and the heat insulating material 14 is taken out, and the lower case 2 is easily lowered along the heat insulating pipe 12. Therefore, the 23 parts of the water stop valve can be easily repaired. Further, reference numeral 33 is a locking groove, the inner wall of which is tilted upward and outward, and after inserting the locking protrusion 7 of the upper case described above into the locking groove, the fixing screw 36 is inserted. While being screwed into the small hole of the locking protrusion 7, the tip of the fixing screw 36 is formed to abut against the slope of the locking groove to prevent the upper case 1 from moving upward.

Next, reference numerals 12 and 12 denote heat insulating pipes, the inside of which is filled with a heat insulating material 18, and water pipes 19, 19 are disposed upright in the center of the heat insulating material 18. In this embodiment, hard urethane was used as the heat insulating material 18, and a vinyl chloride pipe was used as the heat insulating tube.
Reference numeral 3 denotes a fixing plate, which has fitting parts 37, 37 formed on both sides to fit and fix the heat insulating tubes 12, 12, and the tips 38, 38 of the heat insulating tubes 12, 12 are fixed to the locking plate 3.
It is locked at 9.39. Next, 13,13
is a stopper which pushes up the fixing plate 3 along the water pipes 19, 19, firmly fixes the lower case 2 and the heat insulating pipes 12, 12, and then stops the water pipe 1.
Stoppers 13, 13 are fitted into the pipes 9, 19, and formed so as to be firmly pressed against the outer walls of the water pipes 19, 19.

In addition, the depth at which the heat-retaining pipes 12 are buried in the soil is indicated in the middle, in order to standardize the installation work.

As mentioned above, the above-ground water meter box of the present invention is easy to assemble, the upper and lower cases can be easily set, and it has a structure that prevents it from coming off. It can also be used for
