[0001] The utility model belongs to the technical field of water meters, in particular to a water meter cover. Background Art

[0002] With the development of urbanization and people's increasing demands for a better quality of life, the construction and maintenance of water supply systems have become a crucial component of urban management. As a key device for measuring water consumption, the performance of water meters directly impacts the stability of the water supply system and the user experience. However, in practice, traditional water meter cover designs often have shortcomings. Especially in installation environments with limited space, ensuring convenient and quick access to meter inspection and maintenance becomes a pressing issue. Traditional water meter covers mostly use a flip-top design, secured to the meter by a hinge. Manual opening is required to view meter readings or perform maintenance. This design is adequate when space is ample. However, in cramped installation environments, such as basements, closets, or areas with dense pipes, the flip-top cover is often difficult to fully open due to limited space, causing significant inconvenience for users and maintenance personnel.

[0003] Existing water meter covers usually rely on locks or other fixing devices when closing, which not only increases the complexity of operation, but may also lead to the problem that the cover cannot be closed and tightened due to aging or damage of the lock. Especially in outdoor environments, wind and rain may cause the lock to rust, further increasing the difficulty of maintenance. Therefore, there are problems in the prior art such as it is difficult to open the water meter cover in a small space, the closing process is complicated, and the fixing device is easily damaged after long-term use. How to design a water meter cover that can be easily observed and maintained even when the installation space is limited, and simplify its closing process and improve its durability has become the focus of research for those skilled in the art. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the specific implementation manner of the present invention will be clearly and completely described below.

[0025] This application discloses a water meter cover 100, such as Figure 1 As shown, it includes a meter cover seat 11, a hinged portion 12, a fixed portion 13 and a sliding portion 14. A recessed meter cover seat 11 hole is provided on the outer side of the meter cover seat 11. The hinged portion 12 includes a first connecting member 121, a second connecting member 122 and a rotating shaft 123. A penetrating connecting hole is provided on the first connecting member 121. The rotating shaft 123 is provided in the connecting hole and is connected to the first connecting member 121. The rotating shaft 123 is connected to the second connecting member 122. The first connecting member 121 is connected to the meter cover seat 11. The design of the hinged portion 12 allows the meter cover to be easily opened and closed. Through the combination of the first connecting member 121, the second connecting member 122 and the rotating shaft 123, the meter cover can be flexibly rotated, which is convenient for inspection and maintenance of the water meter. The fixing portion 13 is connected to the second connecting member 122, and the fixing portion 13 is hinged to the cover base 11 through the hinge portion 12. A fixing track that is recessed inward is provided on one side of the fixing portion 13 away from the hinge portion 12, and inwardly recessed limiting grooves are provided on both sides of the fixing track. Figure 2 and Figure 3 As shown, a protruding limiting portion 131 is provided at one end of the limiting groove, and the limiting portion 131 is used to limit the moving range of the sliding protrusion 141 to prevent the sliding protrusion 141 from moving out of the fixed track. A clamping portion 132 is provided on one side of the fixing portion 13, and the clamping portion 132 is docked and fixed with the hole of the cover seat 11. The fixing portion 13 can be docked and fixed with the hole of the cover seat 11 through the provided clamping portion 132. Fixing the fixing portion 13 can prevent the sliding portion 14 from affecting the fixing portion 13 and prevent the fixing portion 13 from being unfolded through the hinge portion 12. Figure 4As shown, a downwardly protruding sliding protrusion 141 is provided under the sliding portion 14, and the sliding protrusion 141 is limited in the fixed track by a limiting groove. The matching design between the sliding portion 14 and the fixed portion 13, plus the effect of the limiting portion 131, prevents the sliding portion 14 from accidentally falling off, thereby enhancing the safety of the water meter cover 100. A sliding elastic portion 142 is provided on one side of the sliding portion 14, one end of the sliding elastic portion 142 is connected to one side of the hinged cover of the cover seat 11, and the other side of the sliding elastic portion 142 is connected to the sliding portion 14, and the sliding elastic portion 142 is used to reset the sliding portion 14. After the user pushes the sliding portion 14 to move on the fixed track to watch the water meter, he only needs to let go, and the sliding portion 14 returns to its original position through the reset of the sliding elastic portion 142. The sliding portion 14 moves in the fixed top track through the sliding protrusion 141 provided below, so that the sliding portion 14 slides on the fixed portion 13. When the water meter cover 100 has limited installation space and the reserved flip cover space is insufficient, the water meter can still be observed by sliding the cover open. Due to the design of the sliding portion 14, maintenance personnel can perform inspections and preliminary maintenance without completely disassembling the meter cover, reducing the trouble of disassembly and assembly.

[0026] As an implementation method, Figure 5 and Figure 6 As shown, a downwardly recessed fixing groove is provided on the side away from the sliding portion 14, and an elastic portion 133 and a fixing tooth 134 are provided inside the fixing groove. One end of the elastic portion 133 is connected to the fixing portion 13, and the other end of the elastic portion 133 is connected to the fixing tooth 134. Figure 7As shown, a protruding convex plate 143 is provided on one side of the sliding portion 14 close to the fixing portion 13, and a through hole is provided on the convex plate 143 for the fixing tooth 134 to pass through. At least two corresponding fixing blocks 1431 are provided on the side of the through hole, and a fixing hole is passed through the fixing block 1431. A press switch 1432 is provided above the through hole. The press switch 1432 includes press protrusions 1433 protruding outward on both sides for being placed in the fixing holes. When the sliding portion 14 slides to the through hole through which the fixing tooth 134 passes, the sliding portion 14 is fixed. At this time, the user does not need to push the sliding portion 14 all the time and can directly observe the water meter reading. After using the water meter, when the press switch 1432 is pressed downward, the press switch 1432 abuts against the fixing tooth 134 to disengage from the through hole, and the sliding portion 14 rebounds through the sliding elastic portion 142, thereby returning the sliding portion 14 to its original position. By inserting and engaging the fixed teeth 134 through the through-holes of the raised plate 143 on the sliding portion 14, the sliding portion 14 is securely locked in place, ensuring that the user does not need to continuously apply force to push the sliding portion 14 when observing the water meter reading. After use, the user simply presses the push switch 1432, and the fixed teeth 134 disengage from the through-holes. The sliding portion 14 automatically rebounds to its initial position via the sliding elastic portion 142, eliminating the need for manual reset and simplifying operation. To observe the water meter reading, the user simply pushes the sliding portion 14 into place, whereupon the fixed teeth 134 automatically lock. Once the reading is complete, the sliding portion 14 is reset by pressing the switch 1432, making the entire process simple and quick.

[0027] As an embodiment, the ratio of the length of the fixed portion 13 from the side away from the hinge portion 12 to the hinge portion 12 to the length of the sliding portion 14 from the side away from the hinge portion 12 to the hinge portion 12 is in the range of 1-2:3-4. Such a length ratio design makes the proportion between the fixed portion 13 and the sliding portion 14 reasonable, ensuring that the sliding portion 14 has sufficient length to cover the meter cover and that the fixed portion 13 can provide sufficient support and stability. The longer design of the sliding portion 14 makes it easier for the user to apply force when pushing the sliding portion 14, and the operation is more labor-saving. At the same time, the longer sliding portion 14 also helps to improve the field of view when observing the water meter reading. The fixed portion 13 is relatively short, but it is sufficient to support the weight of the sliding portion 14 and can provide a stable fixing effect to ensure that the sliding portion 14 does not move at will when not in use.

[0028] As an implementation method, Figure 8As shown, a rebound portion 124 is provided on the hinged portion 12, and a first connection slot is recessed downwardly on one side of the first connecting member 121 near the second connecting member 122. One end of the rebound portion 124 is disposed in the first connection slot and connected to the first connecting member 121, while the other end of the rebound portion 124 is connected to the second connecting member 122. The rebound portion 124 allows the water meter cover 100 to automatically open when in use. When the water meter cover 100 needs to be closed, the fixing portion 13 is hingedly provided on one side of the fixing portion 13, which is used to correspond to the hole of the cover base 11. The fixing portion 13 can be docked and fixed with the hole of the cover base 11 through the provided clamping portion 132, thereby fixing the fixing portion 13.

[0029] In one embodiment, the side of the fixing portion 13 proximal to the cover base 11 is made of a magnetic material, and the side of the cover base 11 proximal to the fixing portion 13 is also made of a magnetic material. This magnetic material allows the cover to automatically attach to the cover base 11 when closed, eliminating the need for additional latches or other securing devices and simplifying the closing process. This suction provides a certain closing force, ensuring that the cover is securely fixed to the cover base 11 when closed, preventing accidental opening due to external vibrations, wind, and other factors.

[0030] As an embodiment, a handle 144 is provided on one side of the upper portion of the sliding portion 14 away from the fixing portion 13. The design of the handle 144 allows the user to more easily grasp the sliding portion 14 and facilitates the sliding portion 14 to slide along the fixed track.

[0031] As an embodiment, the sliding portion 14 is provided with a through-hole, and the through-hole is provided with a transparent observation window 145. Through the transparent observation window 145, the water meter reading or other information to be monitored can be directly observed without fully opening the sliding portion 14, thereby improving the convenience of use.
