Description

Technical Field

[0001] The utility model belongs to the technical field of water meter protection, and in particular relates to a protection structure of a modular water meter. Background Art

[0002] Modular water meters are water meters that are broken down into multiple independent modules for easy maintenance and replacement, as well as for adding and upgrading functions. This design makes maintenance more convenient and economical. Modular water meters usually include a water meter body, a metering module, a valve control module, a communication module, etc. These modules can be independently maintained, replaced, and upgraded.

[0003] In order to determine the user's water consumption so as to calculate and collect water charges, meter readers will regularly read the user's water meter. In order to protect the water meter screen and prevent dust from falling on the water meter screen and affecting the meter reader's reading, a protective cover is installed on the outside of the water meter. The protective cover is rotatably connected to the outside of the water meter through a pin shaft, and the protective cover will be flipped open when the meter reader reads the meter.

[0004] However, for the convenience of management, users' water meters are uniformly installed in water meter boxes. Usually, more water meters are installed in the water meter box, which will reduce the space for activities inside the water meter box. When meter readers read the water meters, they cannot open the protective cover, which affects the normal work of meter readers. Utility Model Content

[0005] In order to solve the technical problem that the protection cover cannot be opened, the utility model provides a protection structure of a modular water meter.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A protective structure for a modular water meter comprises a water meter body, a protective cover is installed on the upper surface of the water meter body, a first positioning block is connected to the outside of the protective cover, a shell is installed at a position on the outside of the water meter body corresponding to the first positioning block, the first positioning block is plugged into the shell, a positioning groove is opened in the middle of the first positioning block, an insert block is arranged at a position corresponding to the positioning groove inside the shell, one end of the insert block away from the first positioning block is connected to one end of a spring, the other end of the spring is connected to the inner wall of the shell, a connecting plate is fixedly connected to the middle of the lower surface of the insert block, a rotating plate is arranged below the side of the connecting plate away from the spring, a rotating rod is connected to the lower end of the rotating plate, the rotating rod passes through the shell and is connected to a knob arranged on the outside of the shell.

[0008] Preferably, a sealing ring is adhered to the lower surface of the protective cover, and a sealing groove is provided above the water meter body at a position corresponding to the sealing ring.

[0009] Preferably, three evenly arranged second positioning blocks are connected to the outside of the protective cover away from the first positioning block, and a positioning ear is connected to the outside of the water meter body corresponding to the second positioning block. The second positioning block is inserted into the positioning ear, and an elastic sheet is connected to the outside of the second positioning block.

[0010] Preferably, a first arcuate surface is provided at the lower end of the first positioning block, and a second arcuate surface is provided at a position above the housing corresponding to the first positioning block, and the first arcuate surface and the second arcuate surface are used in coordination.

[0011] Preferably, an inclined surface is provided above the insert block at a position corresponding to the positioning groove, and the inclined surface is used in conjunction with the first arc-shaped surface.

[0012] Preferably, a third arcuate surface is provided at the lower end of the second positioning block, and a fourth arcuate surface is provided at a position above the positioning ear corresponding to the third arcuate surface, and the third arcuate surface and the fourth arcuate surface are used in coordination.

[0013] Preferably, a movable groove is provided at a position of the shell corresponding to the plug-in block, and the plug-in block is slidably connected in the movable groove.

[0014] Beneficial effects of the utility model:

[0015] The meter reader rotates the knob clockwise to rotate the rotating rod and the rotating plate. The rotating plate rotates to contact the connecting plate and squeeze the connecting plate, so that the connecting plate moves to a position away from the first positioning block, thereby causing the insert block to slide into the movable groove. During the process of the insert block sliding into the movable groove, the insert block will be disengaged from the positioning groove, causing the first positioning block to lose its fixation, so that the meter reader can remove the protective cover from the water meter body for meter reading. The space required for removing the protective cover is small, so that the meter reader will not be affected in reading the meter in a compact water meter box.

[0016] After the meter reader finishes reading the water meter, the first positioning block on the protective cover is aligned with the shell and inserted, and the second positioning block and the elastic sheet on the protective cover are aligned with the positioning ear and inserted. During the process of inserting the first positioning block into the shell, it will contact the plug-in block and squeeze the plug-in block, so that the plug-in block slides into the movable groove. During the sliding process, the plug-in block will squeeze the spring, and the spring will shrink and store elastic force when squeezed. When the first positioning block is inserted into the position corresponding to the positioning groove and the plug-in block, the plug-in block will be reset under the action of the spring elastic force and inserted into the positioning groove, so that the first positioning block and the protective cover are fixed. After the second positioning block and the elastic sheet are inserted into the positioning ear, the elastic sheet will press against the inner wall of the positioning ear, thereby strengthening the fixation of the protective cover and preventing the protective cover from falling off.

[0030] See also Figure 1 - Figure 5 As shown, a modular water meter protection structure includes a water meter body 1, and a protective cover 2 is installed on the upper surface of the water meter body 1 to shield and protect the water meter display screen, so as to prevent the water meter display screen from being covered by dust and affecting the meter reading or being damaged;

[0031] A sealing ring 6 is adhered to the lower surface of the protective cover 2, and a sealing groove 61 is provided above the water meter body at a position corresponding to the sealing ring 6. The sealing ring 6 cooperates with the sealing groove 61 to seal between the protective cover 2 and the water meter body 1, preventing dust from entering the water meter body 1 and blocking the water meter display screen;

[0032] A first positioning block 21 is connected to the outer side of the protective cover 2, and three evenly arranged second positioning blocks 5 are connected to the outer side of the protective cover 2 away from the first positioning block 21. The first positioning block 21 and the second positioning block 5 are used to fix the protective cover 2;

[0033] A housing 22 is installed at a position on the outside of the water meter body 1 corresponding to the first positioning block 21, and the first positioning block 21 is plugged into the housing 22. A positioning ear 52 is connected to a position on the outside of the water meter body 1 corresponding to the second positioning block 5, and the second positioning block 5 is plugged into the positioning ear 52. The housing 22 is used to receive the first positioning block 21, and the positioning ear 52 is used to receive the second positioning block 5.

[0034] An elastic sheet 51 is connected to the outer side of the second positioning block 5, and the elastic sheet 51 is used to press against the inner wall of the positioning ear 52, so as to strengthen the fixation of the protective cover 2;

[0035] A first arcuate surface 3 is formed at the lower end of the first positioning block 21, and a second arcuate surface 31 is formed at a position above the housing 22 corresponding to the first positioning block 21. The first arcuate surface 3 and the second arcuate surface 31 cooperate with each other to enable the first positioning block 21 to be inserted into the housing 22 more quickly and accurately, thereby improving efficiency.

[0036] A third arc surface 53 is formed at the lower end of the second positioning block 5, and a fourth arc surface 54 is formed above the positioning ear 52 at a position corresponding to the third arc surface 53. The third arc surface 53 and the fourth arc surface 54 are used in conjunction with each other, so that when the second positioning block 5 is inserted into the positioning ear 52, the second positioning block 5 can be inserted into the positioning ear 52 more quickly and accurately, thereby improving efficiency.

[0037] A positioning groove 23 is provided in the middle of the first positioning block 21, and an insert block 24 is provided at a position corresponding to the positioning groove 23 inside the housing 22. The insert block 24 is inserted into the positioning groove 23 to fix the first positioning block 21 and the protective cover 2;

[0038] An inclined surface 4 is provided above the insert block 24 at a position corresponding to the positioning groove 23. The inclined surface 4 cooperates with the first arc surface 3. When the first positioning block 21 is inserted into the housing 22 and contacts the insert block 24, the first arc surface 3 cooperates with the inclined surface 4 to enable the first positioning block 21 to smoothly squeeze the insert block 24, thereby enabling the insert block 24 to slide into the movable groove 241.

[0039] The housing 22 is provided with a movable groove 241 at a position corresponding to the plug block 24. The plug block 24 is slidably connected in the movable groove 241. The movable groove 241 is used to limit the position of the plug block 24 to prevent the plug block 24 from shifting.

[0040] One end of the plug block 24 away from the first positioning block 21 is connected to one end of a spring 25, and the other end of the spring 25 is connected to the inner wall of the housing 22. The spring 25 is used to reset the plug block 24 and the rotating plate 27.

[0041] A connecting plate 26 is fixedly connected to the middle of the lower surface of the plug block 24. A rotating plate 27 is arranged below the side of the connecting plate 26 away from the spring 25. A rotating rod 271 is connected to the lower end of the rotating plate 27. The rotating rod 271 passes through the housing 22 and is connected to a knob 28 arranged on the outer side of the housing 22.

[0042] When in use, the meter reader rotates the knob 28 clockwise to rotate the rotating rod 271 and the rotating plate 27, and the rotating plate 27 rotates to contact the connecting plate 26 and squeeze the connecting plate 26, so that the connecting plate 26 moves to a position away from the first positioning block 21, so that the insert block 24 slides into the movable groove 241. During the process of the insert block 24 sliding into the movable groove 241, the insert block 24 will be separated from the positioning groove 23, so that the first positioning block 21 loses its fixation, so that the meter reader can remove the protective cover 2 from the water meter body 1 to read the meter. The space required for removing the protective cover 2 is small, so that the meter reader will not be affected in reading the meter in the compact water meter box.

[0043] After the meter reader finishes reading the water meter, the first positioning block 21 on the protective cover 2 is aligned with the shell 22 and inserted, and the second positioning block 5 and the elastic sheet 51 on the protective cover 2 are aligned with the positioning ear 52 and inserted. During the process of inserting the first positioning block 21 into the shell 22, it will contact the plug block 24 and squeeze the plug block 24, so that the plug block 24 slides into the movable groove 241. During the sliding process, the plug block 24 will squeeze the spring 25, and the spring 25 will shrink and store elastic force when squeezed. When the first positioning block 21 is inserted into the position corresponding to the positioning groove 23 and the plug block 24, the plug block 24 will reset under the action of the elastic force of the spring 25 and be inserted into the positioning groove 23, so that the first positioning block 21 and the protective cover 2 are fixed. After the second positioning block 5 and the elastic sheet 51 are inserted into the positioning ear 52, the elastic sheet 51 will press against the inner wall of the positioning ear 52, thereby strengthening the fixation of the protective cover 2 and preventing the protective cover 2 from falling off.
