Description

Technical Field

[0001] The present application relates to the technical field of mechanical water meters, and in particular to a quick-install water meter. Background Art

[0002] A mechanical water meter is a meter used to measure water flow. It is mainly used in households, commercial and industrial places to measure water usage by monitoring the volume or flow rate of water flowing through, so as to charge for water, manage water resources and monitor water usage.

[0003] The main body of the mechanical water meter includes a meter head and a pot-shaped lower part of the water meter. A gear set and a data display are installed in the meter head, and a turbine and a sealing assembly are installed in the lower part of the water meter. The sealing assembly is used to ensure the overall sealing of the water meter to prevent water leakage and the influence of the external environment. When water flows through the water meter, the turbine is driven by the water flow to rotate, and the rotational motion is transmitted to the digital display in the meter head through the gear set, and the digital display screen shows the reading.

[0004] The meter head and the lower part of the water meter are fixed by installing a rotating hoop on both of them at the same time. The rotating hoop is connected to the outer ends of the meter head and the lower part of the water meter by threads. The rotating hoop itself is relatively large. In order to ensure the stability of the installation of the meter head and the lower part of the water meter, it is necessary to use a tool to tighten the rotating hoop when installing the rotating hoop, which is rather troublesome. In addition, the rotating hoop is usually made of metal (such as iron or steel), which may rust in a humid environment. Rust will make the metal surface rough and even corrode, affecting the rotation of the rotating hoop and making it inconvenient for subsequent disassembly. Combining the above two points, the existing rotating fixing structure still has room for improvement. Utility Model Content

The upper end of the extension 322 is provided with an embedding groove 323 for the horizontal plate 34 to be embedded, and the bottom of the embedding groove 323 is provided with an upper insertion hole 324 for the clamping member 33 to be inserted; the lower end of the protective shell 32 is provided with a clamping interface 325.

[0043] After the protective shell 32 covers the open ring 31, the clamping member 33 is inserted from top to bottom, so that the horizontal plate 34 is embedded in the embedding groove 323. At this time, the clamping member 33 is inserted into the upper insertion hole 324, the lower insertion hole 315 and the clamping interface 325 in sequence, and is clamped at the clamping interface 325. The upper end surface of the hook plate at the lower part of the clamping member 33 is pressed against the lower end surface of the extension part 322. The width of the clamping interface 325 is greater than or equal to the width of the lower end of the clamping member 33, that is, the clamping interface 325 is large enough for the lower part of the clamping member 33 to be inserted.

[0044] Reference Figure 2 , Figure 4 and Figure 5 , an observation gap 43 is provided at the upper end of the meter cover 4, and the observation gap 43 runs through the meter cover 4 from top to bottom, and a sliding cover 5 is covered at the observation gap 43.

Other pipes may be connected to the installation place of the water meter, which will affect the upward flipping of the meter cover 4. Therefore, on the basis of the provision of the flip cover, an additional sliding cover 5 that can rotate in the circumferential direction is provided to improve the convenience of viewing the numerical value and comprehensively deal with the dilemma of insufficient observation space when reading. In order to facilitate sliding, a sliding groove 52 is concavely provided on the left side of the upper end of the sliding cover 5.

[0045] A slot 45 is concavely formed on the left side of the upper end of the meter cover 4, and a block 53 is convexly formed on the left side of the lower end of the slide cover 5. When the block 53 is embedded in the slot 45, the slide cover 5 completely covers the indication.

[0046] The implementation principle of a quick-install water meter in an embodiment of the present application is as follows: the meter head 2 is placed at the upper end of the lower part 1 of the water meter, and the first matching piece 121 is inserted in cooperation with the second piece to align the two. The open ring 31 is sleeved from top to bottom, so that the open ring 31 simultaneously presses against the outer periphery of the shell 11 and the outer periphery of the meter head 2, and the open ring 31 shields the joint between the shell 11 and the meter head 2. Then, the protective shell 32 is sleeved from top to bottom, and the clamping piece 33 is inserted from top to bottom, so that the lower end of the clamping piece 33 is deformed to pass through the lower end of the clamping block 313 and the lower end of the protective shell 32. When the clamping piece 33 is no longer squeezed, the clamping piece 33 spontaneously restores its deformation and is finally clamped to the lower end of the protective shell 32. The horizontal plate 34 is embedded in the embedding groove 323. At this time, the water meter is installed as a whole.

[0047] When disassembly is required, it is only necessary to pinch the clamping parts 33 on both sides to disengage them from bottom to top, and then pull out the protective shell 32 and the open ring 31 in turn to proceed with subsequent disassembly.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
