Description

Technical Field

[0001] This utility model relates to the field of water meter technology, specifically to a water meter with a flip-top structure. Background Technology

[0002] Existing water meters typically have a flip-top cover. Closing the flip-top provides some protection for the internal structure of the water meter and effectively prevents dust from entering the meter's viewing window. However, the direction of the actuating part on the existing flip-top cover is fixed. During installation, this actuating part may be close to a wall or pipeline, making the flip-top operation inconvenient. Furthermore, after the staff flips up the cover to complete the meter reading, they may inadvertently fail to close the cover properly. This leaves a gap between the flip-top and the top of the water meter. Over time, a lot of dust can accumulate on the water meter, making it difficult to read the meter on subsequent readings. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of the aforementioned technologies by proposing a water meter with a flip-top structure, thereby solving the problems described above.

[0004] This utility model provides a water meter with a flip-top structure, including a water meter body, a mounting ring, an annular sleeve, and a top cover. The annular sleeve is detachably connected to the water meter body and is used to fix the mounting ring. The top cover is rotatably mounted on the mounting ring and is provided with a toggle part. The mounting ring is provided with an elastic element, a fan-shaped smooth area, and a limiting area. The top cover is provided with a serrated part, and a gap is left between the serrated part and the smooth area. The elastic element is used to drive the serrated part to slide in the smooth area to drive the top cover to close. The limiting area is provided with a limiting mechanism, which is used to lock the serrated part to keep the top cover in the flip-top state.

[0005] Preferably, the water meter body is provided with an annular platform for the mounting ring to fit on, and the annular platform is provided with an abutting ring that abuts against the upper end of the mounting ring. The annular platform is threadedly connected to the water meter body and the mounting ring is pressed against the annular platform by the abutting ring.

[0006] Preferably, the outer periphery of the annular sleeve is provided with stripes to increase friction.

[0007] Preferably, the top cover is provided with a connecting post, and a rotating post and the serrated part are provided on both sides of the connecting post. An annular groove is provided on both sides of the mounting ring for the rotating post to be rotatably mounted. The rotating post extends out of the annular groove so that a gap is left between the serrated part and the smooth area.

[0008] Preferably, a connecting rod is provided on the rotary column, the connecting rod passes through the annular groove, and the elastic element acts on the connecting rod to drive the serrated part to slide in the smooth area to drive the top cover to close.

[0009] Preferably, the elastic element is a torsion spring, which is sleeved on the connecting rod, with one end of the torsion spring fixed to the mounting ring and the other end of the torsion spring connected to the connecting rod.

[0010] Preferably, the limiting mechanism includes an elastic strip and a plurality of limiting teeth. The elastic strip is disposed on the mounting ring and has an arc-shaped structure. The plurality of limiting teeth are arranged on the elastic strip, and the elastic strip is used to drive the plurality of limiting teeth to engage with the serrated portion.

[0011] Preferably, the mounting ring is provided with an annular wall, and the top cover is provided with a collar for covering the annular wall.

[0012] Preferably, a magnetic block is provided on the collar, the magnetic block is located below the actuating part, and an iron block is provided on the mounting ring to magnetically engage with the magnetic block.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] The position of the mounting ring can be adjusted by rotating it after removing the ring sleeve. Then, the mounting ring can be re-fixed by the ring sleeve, allowing the actuating part to rotate to a position that is convenient for manual operation, facilitating the flip-cover operation and ensuring the normal progress of meter reading. Through the cooperation of the limiting mechanism and the smoothing zone, when the top cover is manually opened, the serrated part moves along the smoothing zone to the limiting zone. The limiting mechanism can lock the serrated part to keep the top cover open. The tightening force of the limiting mechanism is greater than the elastic force of the elastic element. When the operator closes the top cover, the serrated part moves from the limiting zone to the smoothing zone, releasing the locking state of the limiting mechanism and driving the top cover to close automatically under the action of the elastic element. This can effectively avoid the problem of the top cover not closing properly and achieve a good dustproof effect. Attached Figure Description

Detailed Implementation

[0028] This section will describe in detail the specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0029] Example 1:

[0030] Reference Figures 1 to 11This utility model provides a water meter with a flip-top structure, including a water meter body 1, a mounting ring 2, an annular sleeve 3, and a top cover 4. The annular sleeve 3 is detachably connected to the water meter body 1 and is used to fix the mounting ring 2. The top cover 4 is rotatably mounted on the mounting ring 2 and is provided with a toggle part 41. The mounting ring 2 is provided with an elastic element 21, a fan-shaped smooth area 22, and a limiting area 23. The top cover 4 is provided with a serrated part 42, and a gap is left between the serrated part 42 and the smooth area 22. The elastic element 21 is used to drive the serrated part 42 to slide in the smooth area 22 to drive the top cover 4 to close. The limiting area 23 is provided with a limiting mechanism 5, which is used to clamp the serrated part 42 to keep the top cover 4 in the flip-top state.

[0031] By disassembling the annular sleeve 3, the position of the mounting ring 2 can be adjusted as needed. Then, by re-fixing the mounting ring 2 with the annular sleeve 3, the actuating part 41 can be rotated to a position that is convenient for manual operation, facilitating the flip-cover operation and the normal progress of meter reading. Through the cooperation of the limiting mechanism 5 and the smooth area 22, when the top cover 4 is manually opened, the serrated part 42 moves along the smooth area 22 to the limiting area 23. The limiting mechanism 5 can lock the serrated part 42 to keep the top cover 4 open. The tightening force of the limiting mechanism 5 is greater than the elastic force of the elastic element 21. When the staff closes the top cover 4, the serrated part 42 moves from the limiting area 23 to the smooth area 22, releasing the locking state of the limiting mechanism 5 and driving the top cover 4 to close automatically under the action of the elastic element 21. This can effectively avoid the problem of the top cover 4 not closing properly, achieve a good dustproof effect, and reduce the occurrence of difficulties in reading the meter next time due to dust accumulation. Among them, after the limiting mechanism 5 clamps the sawtooth part 42, the top cover 4 can still be flipped under manual force. During the flipping process of the top cover 4, the elastic force of the elastic element 21 is always less than the clamping force of the limiting mechanism 5 clamping the sawtooth part 42.

[0032] Specifically, the water meter body 1 is provided with an annular platform 11 for the installation ring 2 to be fitted, and the annular sleeve 3 is provided with an abutting ring 31 that abuts against the upper end of the installation ring 2. The annular sleeve 3 is threadedly connected to the water meter body 1 and the installation ring 2 is pressed onto the annular platform 11 by the abutting ring 31.

[0033] When the position of the actuating block needs to be adjusted, loosen the annular sleeve 3, then rotate the mounting ring 2 to adjust the position of the actuating block. After adjustment, press the top cover 4 with one hand to fix the mounting ring 2 and tighten the annular sleeve 3 to fix the mounting ring 2 on the annular platform 11. This achieves the adjustment of the position of the actuating block, which facilitates the rotation of the actuating part 41 to a position that is convenient for manual operation, provides convenience for flip-cover operation, and facilitates the normal operation of meter reading.

[0034] Specifically, the outer periphery of the annular sleeve 3 is provided with stripes 32 to increase friction.

[0035] By setting stripes 32 to increase friction, it is easy to rotate the annular sleeve 3 to adjust the position of the actuating block.

[0036] In other embodiments, the central angle of the smoothing area 22 can be designed to be 90°, the central angle of the limiting area 23 can be designed to be 90°, and the central angle of the serrated portion 42 can be designed to be 30°. When the top cover 4 is closed, the lower end of the serrated portion 42 is on the same horizontal plane as the lower end of the smoothing area 22. During the opening of the top cover 4, when the top cover 4 rotates 60°, the upper end of the serrated portion 42 rotates to the junction of the smoothing area 22 and the limiting area 23. As the top cover 4 continues to rotate, the serrated portion 42 gradually moves to the limiting area 23 and is locked by the limiting mechanism 5. When the top cover 4 is opened 90°, the serrated portion 42 is fully open.

[0037] Example 2:

[0038] Reference Figures 1 to 11 In conjunction with the technical solution of Embodiment 1, in this embodiment, the top cover 4 is provided with a connecting post 43, and both sides of the connecting post 43 are provided with a rotating post 44 and a serrated part 42. Both sides of the mounting ring 2 are provided with annular grooves 24 for the rotating post 44 to be rotated and installed. The rotating post 44 extends out of the annular groove 24 so that a gap is left between the serrated part 42 and the smooth area 22.

[0039] By rotating the rotary column 44 and the annular groove 24, the rotary column 44 extends out of the annular groove 24 to leave a gap between the serrated part 42 and the smooth area 22, that is, the serrated part 42 will not abut against the smooth area 22, which is conducive to the elastic element 21 driving the serrated part 42 to slide in the smooth area 22 so as to drive the top cover 4 to automatically close in place.

[0040] Specifically, a connecting rod 6 is provided on the rotary column 44. The connecting rod 6 passes through the annular groove 24. The elastic element 21 acts on the connecting rod 6 to drive the serrated part 42 to slide in the smooth area 22 to drive the top cover 4 to close.

[0041] When the top cover 4 is opened, the connecting rod 6 rotates with the top cover 4. At this time, the elastic element 21 undergoes elastic deformation, and the serrated part 42 slides through the smooth area 22 and is locked by the limiting mechanism 5 at the limiting area 23. The tightening force of the limiting mechanism 5 on the serrated part 42 is greater than the elastic force of the elastic element 21. At this time, the top cover 4 remains open. When the top cover 4 is closed, the serrated part 42 slides from the limiting area 23 to the smooth area 22, and the elastic element 21 releases its elastic force, which drives the top cover 4 to close automatically through the connecting rod 6, thus achieving a good dustproof effect.

[0042] Specifically, the elastic element 21 is a torsion spring, which is sleeved on the connecting rod 6. One end of the torsion spring is fixed on the mounting ring 2, and the other end of the torsion spring is connected to the connecting rod 6.

[0043] Example 3:

[0044] Reference Figures 1 to 11Combining the technical solutions of Embodiments 1 and 2, in this embodiment, the limiting mechanism 5 includes an elastic strip 51 and a plurality of limiting teeth 52. The elastic strip 51 is disposed on the mounting ring 2 and has an arc-shaped structure. The plurality of limiting teeth 52 are arrayed on the elastic strip 51, and the elastic strip 51 is used to drive the plurality of limiting teeth 52 to engage with the serrated portion 42. The two ends of the elastic strip 51 are connected to the mounting ring 2, and the inner and outer arcs of the elastic strip 51 are spaced apart from the mounting ring 2, allowing the elastic strip 51 to bend and return to its original position under its own elasticity.

[0045] When the serrated part 42 moves to the limiting area 23, several limiting teeth 52 engage with the serrated part 42 to lock the top cover 4. During the process of manually flipping the top cover 4, the serrated part 42 slides relative to the several limiting teeth 52. The serrated part 42 pushes away the limiting tooth 52 corresponding to the current position and moves to the next limiting tooth 52. The next limiting tooth 52 engages with the serrated part 42 under the elastic force of the elastic strip 51. That is, during the process of the serrated part 42 moving to the limiting area 23 and continuing to flip the top cover 4, several serrated parts 42 can lock the serrated part 42 at any time to keep the top cover 4 in the open state.

[0046] Specifically, the mounting ring 2 is provided with an annular wall 25, and the top cover 4 is provided with a collar 45 for covering the annular wall 25.

[0047] The structure of the collar 45 covering the annular wall 25 improves the sealing performance when the top cover 4 is closed.

[0048] Specifically, a magnetic block 7 is provided on the collar 45, the magnetic block 7 is located below the actuating part 41, and an iron block 8 is provided on the mounting ring 2 to magnetically engage with the magnetic block 7.

[0049] With the cooperation of the magnetic block 7 and the iron block 8, when the top cover 4 is automatically closed under the action of the elastic element 21, the magnetic block 7 can attract the iron block 8 to keep the top cover 4 in a closed state, making it difficult for the top cover 4 to be opened accidentally, thus further improving the dustproof effect.

[0050] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of this utility model without departing from the scope of the technical solution of this utility model shall fall within the protection scope of this technical solution.
