The number of the first sealing block 4 and the second sealing block 5 is several and arranged circumferentially, and a positioning mechanism 6 is arranged between the observation plate 3 and the sealing cover 2 for easy gluing.

[0020] The above scheme is adopted: by setting a water meter body 1, a sealing cover 2, an observation plate 3, a first sealing block 4, a second sealing block 5 and a positioning mechanism 6, when in use, first rotate the sealing cover 2 on the water meter body 1, and fix the sealing cover 2 on the water meter body 1 through a threaded connection. When the sealing cover 2 is rotated to the water meter body 1, the first sealing block 4 contacts the second sealing block 5. Since the first sealing block 4 and the second sealing block 5 are inclined, the sealing cover 2 is continued to be rotated so that the first sealing block 4 and the second sealing block 5 are squeezed against each other until the sealing cover 2 cannot be rotated. At this time, the sealing effect between the sealing cover 2 and the water meter body 1 is the best, and then the positioning mechanism 6 is used to position the observation plate 3 and the sealing cover 2, so that the glue can be better poured between the observation plate 3 and the sealing cover 2, the glue connection is more stable, and the sealing of the sealing cover 2 is increased.

[0021] refer to Figure 3 The positioning mechanism 6 includes a positioning groove 601 and a positioning block 602. The positioning groove 601 is arranged at the inner bottom of the sealing cover 2. The number of the positioning grooves 601 is several and they are arranged circumferentially. The positioning block 602 is arranged on the lower surface of the observation plate 3. The positioning block 602 is arranged corresponding to the positioning groove 601.

[0022] The above scheme is adopted: by setting the positioning groove 601 and the positioning block 602, when in use, the observation plate 3 is first positioned by the cooperation of the positioning groove 601 and the positioning block 602 to avoid the observation plate 3 from tilting and shifting in the sealing cover 2, and then glue is poured between the observation plate 3 and the sealing cover 2 to avoid instability of the observation plate 3 in the sealing cover 2 during glue pouring, thereby improving the sealing of the observation plate 3 and the sealing cover 2.

[0023] refer to Figure 1 , the side wall of the observation plate 3 is provided with glue pouring grooves 7 for facilitating glue pouring, and the glue pouring grooves 7 are multiple and arranged in a circle.

[0024] The above scheme is adopted: by setting the glue pouring groove 7, when the contact point between the observation plate 3 and the sealing cover 2 is glued, the glass glue can enter the glue pouring groove 7, increasing the contact area between the glass glue and the observation plate 3 and the sealing cover 2, so that the sealing effect between the observation plate 3 and the sealant is better.

[0025] refer to Figure 1 A sealing cover 8 is hinged on the upper surface of the sealing cover 2, a mounting groove 9 is provided on the upper surface of the sealing cover 2, a magnetic block 10 is provided inside the mounting groove 9, a magnetic sheet 11 is provided on the lower surface of the sealing cover 8, and the magnetic sheet 11 is provided corresponding to the magnetic block 10.

[0026] The above scheme is adopted: by setting the sealing cover 8, the installation groove 9, the magnetic block 10 and the magnetic sheet 11, when in use, the sealing cover 8 can first seal the sealing cover 2, and then the installation groove 9 can install the magnetic block 10, and the sealing cover 8 can be easily opened and closed by the coordinated use of the magnetic sheet 11 and the magnetic block 10.

[0027] refer to Figure 1 The upper surface of the sealing cover 8 is provided with a groove 12 for providing a fulcrum for the user to open the sealing cover 8 .

[0028] The above solution is adopted: by providing the groove 12 , when in use, the groove 12 can provide a fulcrum for the staff, making it convenient for the staff to open the sealing cover 8 .

[0029] refer to Figure 1 A vertical plate 13 for increasing friction is arranged on the side wall of the sealing cover 2, and the number of the vertical plates 13 is several and they are arranged in a circle.

[0030] The above solution is adopted: by providing the vertical plate 13, since the sealing cover 2 and the water meter body 1 are threadedly connected, the vertical plate 13 can increase the friction between the staff and the sealing cover 2, which can facilitate the staff to rotate the sealing cover 2.

[0031] The working principle of this utility model:

[0032] When in use, first rotate the sealing cover 2 on the water meter body 1, and fix the sealing cover 2 on the water meter body 1 through threaded connection. When the sealing cover 2 is rotated to the water meter body 1, the first sealing block 4 contacts the second sealing block 5. Since the first sealing block 4 and the second sealing block 5 are arranged obliquely, continue to rotate the sealing cover 2 to squeeze the first sealing block 4 and the second sealing block 5 against each other until the sealing cover 2 cannot be rotated. At this time, the sealing cover 2 and the water meter body 1 have the best sealing effect. Then, the observation plate 3 is positioned by the cooperation of the positioning groove 601 and the positioning block 602 to prevent the observation plate 3 from tilting in the sealing cover 2. The phenomenon of offset is then treated by glue pouring between the observation plate 3 and the sealing cover 2 to avoid instability of the observation plate 3 in the sealing cover 2 during glue pouring, thereby improving the sealing performance of the observation plate 3 and the sealing cover 2; when glue is poured at the contact point between the observation plate 3 and the sealing cover 2, the glass glue can enter the glue pouring groove 7, thereby increasing the contact area between the glass glue and the observation plate 3 and the sealing cover 2, thereby making the sealing effect between the observation plate 3 and the sealant better; then the sealing cover 8 can seal the sealing cover 2, and then the mounting groove 9 can install the magnetic block 10; through the coordinated use of the magnetic sheet 11 and the magnetic block 10, the sealing cover 8 can be easily opened and closed.
