[0030] This technical solution utilizes the setting of the sealing door 2 and the hinge 3. When in use, the box body 1 is moved to the specified position, and the installation position of the water meter box is determined. The box body 1 is tightened by expansion bolts to prevent it from loosening. The water meter and other components are further installed in the box body 1, and the sealing door 2 is rotated to close so that the sealing door 2 is tightly attached to the box body 1, and then locked.

[0031] Embodiment 2: The technical content disclosed in this embodiment is an improvement made on the basis of the above embodiment 1. When the existing water meter box is used for a long time, it is affected by external factors and the sliding groove is at risk of being blocked. It needs to be manually cleaned by the staff, which affects the user experience. The technical solution of this invention is as follows: Figure 1 and Figure 4-Figure 6As shown, a water meter box installation component is disclosed, wherein a side wall of a box body 1 is provided with a limiting groove 101, and a fixing block 4 is fixedly connected in the box body 1, a groove 401 is provided in the middle of the fixing block 4, and a fixing rod 5 is fixedly connected in the groove 401, a clamping block 6 is fixedly connected to the top of the fixing rod 5, and a movable block 7 is slidably connected to the outer side of the fixing rod 5, a lower pressing block 13 is provided on the sealing door 2, and the bottom end of the lower pressing block 13 penetrates and extends out of the sealing door 2, and a second limiting plate 14 is movably connected in the lower pressing block 13, two limiting grooves 101 are symmetrically provided with respect to the box body 1, and the opposite sides of the two limiting grooves 101 are aligned with the limiting mechanism, and the upper and lower ends of the movable block 7 are provided with There is an inclined surface, and the bottom end of the clamping block 6 is consistent with the upper end surface of the movable block 7, and the upper end of the clamping block 6 is provided with a slope at one end, the lower pressing block 13 is slidably connected to the sealing door 2, and a compression spring 1301 is connected between the lower pressing block 13 and the sealing door 2, and an elastic telescopic structure is formed between the lower pressing block 13 and the sealing door 2 through the compression spring 1301, the bottom end of the second limiting plate 14 is provided with an inclined surface, and the second limiting plates 14 are symmetrically arranged with two lower pressing blocks 13, and the ends of the two lower pressing blocks 13 close to the second limiting plate 14 are fixedly connected with auxiliary springs 1401, and the ends of the auxiliary springs 1401 away from the second limiting plate 14 are fixedly connected to the inner wall of the lower pressing block 13.

[0032] In this technical solution, Figure 1 As shown, by utilizing the setting of the block 6 and the second limit plate 14, the second limit plate 14 is moved downward synchronously under the drive of the lower pressure block 13, so that the second limit plate 14 squeezes the auxiliary spring 1401 to contract. When the second limit plate 14 moves below the block 6, the squeezing force of the auxiliary spring 1401 disappears, so that the auxiliary spring 1401 drives the second limit plate 14 to reset and move, so that the second limit plate 14 and the block 6 are against each other. The structure is simple, and quick installation is achieved, thereby improving installation efficiency.

[0033] Its use is as Figure 4-Figure 6 The technical solution shown is that, first, after the sealing door 2 is rotated to fit with the box body 1, the pressing block 13 will be aligned with the slot 401 in the middle of the fixing block 4, and then the pressing block 13 is manually pressed so that the pressing block 13 drives the second limiting plate 14 to slide into the slot 401 at the same time, and the pressing block 13 will squeeze the compression spring 1301 to contract, and the second limiting plate 14 will slide in line with the upper surface of the card block 6. At this time, continue to press the pressing block 13 so that the second limiting plate 14 slides to both sides to squeeze the auxiliary spring 1401 to contract. When the second limiting plate 14 moves to the bottom of the card block 6, stop pressing the pressing block 13. At this time, the second limiting plate 14 is reset under the elastic force of the auxiliary spring 1401, so that the second limiting plate 14 fits with the bottom end of the card block 6, limits the sealing door 2, and completes the installation.

[0034] Embodiment 3: The technical content disclosed in this embodiment is a further improvement based on the above-mentioned embodiment 1 and embodiment 2. Since the locking block will be driven by the spring to bounce off after the lock body is opened, its anti-theft effect is poor. In order to further solve this technical problem, the technical solution is as follows: Figure 2 , Figure 3 and Figure 7 As shown, a secondary fixing assembly of a water meter box is disclosed, wherein a rotating disk 8 is rotatably installed inside a sealed door 2, a guide groove 801 is provided in the middle of the rotating disk 8, and an arc groove 802 is provided on the rotating disk 8 outside the guide groove 801, and a limiting mechanism is slidably connected in the arc groove 802, a threaded rod 9 is movably connected in the guide groove 801, and a slider 10 is fixedly connected to the outside of the threaded rod 9, and the limiting mechanism includes a moving part 11 and a first limiting plate 12, the moving part 11 is slidably arranged in the arc groove 802, and the arc groove 802 is slidably connected to the rotating disk ... 02 and two movable members 11 are symmetrically arranged about the turntable 8, and the bottom ends of the two movable members 11 are fixedly connected with the first limit plates 12, the first limit plates 12 are slidably connected to the inner wall of the sealing door 2, and the ends of the two first limit plates 12 that are separated from each other penetrate and extend out of the sealing door 2, and the extended ends of the first limit plates 12 are aligned with the limit groove 101, the top end of the threaded rod 9 penetrates and extends out of the sealing door 2, and the threaded rod 9 is threadedly connected to the sealing door 2, and the slider 10 on the outside of the threaded rod 9 is slidably connected to the guide groove 801

[0035] In this technical solution, Figure 2 As shown, by utilizing the arrangement of the turntable 8 and the threaded rod 9, the threaded rod 9 drives the turntable 8 to rotate synchronously when rotating, and the turntable 8 drives the first limit plate 12 to move into the limit groove 101 when rotating to perform secondary limiting, and the threaded rod 9 limits the turntable 8 after being tightened, thereby reducing the risk of successful intrusion, enhancing security, and improving anti-theft performance.

[0036] Its use is as Figure 3 and Figure 7 According to the technical solution shown in the figure, after the preliminary installation is completed, the threaded rod 9 is rotated with the help of an external object so that the threaded rod 9 is threadedly engaged with the sealing door 2, thereby moving downward. Then, the threaded rod 9 drives the slider 10 to rotate synchronously, so that the slider 10 drives the turntable 8 to rotate while sliding downward along the guide groove 801. When the turntable 8 rotates, it drives the arc groove 802 to rotate, so that the moving member 11 slides in the arc groove 802. At the same time, the moving member 11 drives the first limiting plate 12 to slide and extend along the inner wall of the sealing door 2, so that the first limiting plate 12 enters the limiting groove 101, and the sealing door 2 is limited for the second time. In addition, the threaded rod 9 is threadedly connected to the sealing door 2, so that the turntable 8 is not easy to shake, thereby improving the stability of the connection.

[0037] When it is necessary to inspect and repair the components inside the box body 1, it is necessary to first rotate the threaded rod 9 so that the threaded rod 9 drives the turntable 8 to rotate in the opposite direction. At this time, the guide groove 801 cooperates with the moving part 11 to drive the first limit plate 12 away from the limit groove 101, thereby releasing the limit on the sealing door 2. Then, the lower pressing block 13 is pressed downward so that the lower pressing block 13 squeezes the compression spring 1301 and drives the second limit plate 14 to continue to move downward. At this time, the second limit plate 14 will fit with the upper surface of the movable block 7 and slide along the surface of the movable block 7. The second limit plate 14 slides to both sides to squeeze the auxiliary spring 1401 to contract. When the second limit plate 14 moves to below the movable block 7, the second limit plate 14 is reset. At this time, the lower pressing block 13 is pulled so that the lower pressing block 13 drives the second limit plate 14 to move up and down. The second limit plate 14 will drive the movable block 7 to slide along the surface of the fixed rod 5. After the movable block 7 is fitted with the bottom end of the card block 6, it stops moving. At this time, the second limit plate 14 will slide along the surfaces of the movable block 7 and the card block 6 in turn, and the sealing door 2 can be opened.
