Description

Technical Field

[0001] The present application relates to the technical field of water meters, and in particular to a dry single-flow meter with adjustable reading direction. Background Art

[0002] A water meter is an instrument that measures water flow, mostly the cumulative flow of water. It records the amount of water used by users within a certain period of time and is an important tool for water supply management and fee settlement. Water meters are divided into wet water meters and dry water meters. In dry water meters, the metering impeller is separated from the central gear of the counter, and the upper end of the metering impeller is coupled with the magnetic element at the lower end of the central gear by a magnetic element (magnetic ring or cylindrical magnet). When the water flow drives the metering impeller to rotate, the magnetic element at the upper end of the metering impeller and the magnetic element at the lower end of the central gear attract or repel each other, thereby driving the central gear to rotate synchronously, and the central gear drives the counter to record the amount of water flowing through the water meter.

[0003] The installation site of the water meter is often narrow and subject to many restrictions, and the orientation of the water meter is fixed, which leads to many inconveniences when reading the meter number on the counter, so further improvement is needed. Utility Model Content

[0004] In order to flexibly adjust the reading direction of the water meter and improve the convenience of reading, the present application provides a dry single-flow meter with adjustable reading direction.

[0005] The present application provides a dry single-flow meter with adjustable reading direction, which adopts the following technical solution:

[0006] A dry-type single-flow meter with adjustable reading direction comprises a water meter housing with a metering cavity, a metering support arranged on the water meter housing, a protective cover shell rotatably connected to the water meter housing about its own axis, and a copper-sealed counter coaxially fixedly connected to the protective cover shell, wherein the copper-sealed counter is coaxial with the metering support, the metering support is coaxially rotatably connected with a metering impeller built into the metering cavity, and the two sides of the water meter housing are respectively provided with a water inlet pipe opening and a water outlet pipe opening connected to the metering cavity.

[0007] By adopting the above technical solution, when the reading direction of the water meter needs to be adjusted, the protective cover shell is rotated to drive the copper-sealed counter to rotate and adjust around its own axis, thereby improving the convenience of reading.

[0008] Preferably, the upper portion of the water meter housing has an installation port connected to the metering chamber, the inner wall of the installation port has a sink groove for placing the metering support, the water meter housing is detachably connected to a mounting ring seat, the inner wall of the mounting ring seat is coaxially fixed with an anti-slip ring abutting the metering support, and the protective cover shell is coaxially rotatably connected to the mounting ring seat.

[0009] By adopting the above technical solution, after the metering support is placed in the sink through the installation opening, the installation ring seat is then assembled, and the anti-slip ring of the installation ring seat abuts against the metering support, effectively limiting the possibility of the metering support slipping out of the installation opening.

[0010] Preferably, an elastic ring pad is provided between the metering support and the anti-slip ring.

[0011] By adopting the above technical solution, an elastic ring pad is added between the metering support and the anti-slip ring, which effectively prevents the anti-slip ring and the metering support from rigid contact. Under the tightening force of the elastic ring pad, the metering support and the water meter housing are in a relatively fixed state.

[0012] Preferably, an outer peripheral wall of the water meter housing at the installation opening is provided with an external thread, and an inner peripheral wall of the installation ring seat has an internal thread threadedly connected to the external thread.

[0013] By adopting the above technical solution, the mounting ring seat is sleeved on the water meter housing by means of threads, thereby improving the convenience of disassembly and assembly of the mounting ring seat.

[0014] Preferably, the protective cover shell is sleeved on the upper part of the mounting ring seat, a rotating ring groove is coaxially arranged on the upper part of the mounting ring seat, and a rotating buckle embedded in the rotating ring groove is protruded from the inner peripheral wall of the protective cover shell.

[0015] By adopting the above technical solution, the rotational assembly of the protective cover shell and the mounting ring seat is achieved through the rotating ring groove and the rotating buckle.

[0016] Preferably, the lower coaxial rotating sleeve of the mounting ring seat is provided with an anti-theft ring sleeve, and the upper rotating sleeve of the anti-theft ring sleeve is arranged on the lower part of the protective cover shell.

[0017] By adopting the above technical solution, an anti-theft ring sleeve is added, which completely covers and shields the lower part of the mounting ring seat, and the protective cover shell completely covers and shields the upper part of the mounting ring seat, so that the mounting ring seat has a hidden structure, which effectively prevents the mounting ring seat from being disassembled and stolen.

[0018] Preferably, a mounting convex edge protrudes from the lower part of the mounting ring seat, a limiting convex ring abutting against the upper end face of the mounting convex edge is coaxially fixed to the inner circumferential wall of the anti-theft ring sleeve, and the lower end face of the protective cover shell abuts against the upper end face of the limiting convex ring.

[0019] By adopting the above technical scheme, when installing the anti-theft ring sleeve, the anti-theft ring sleeve is firstly sleeved on the mounting ring seat so that the limiting convex ring abuts against the upper end surface of the mounting convex edge, and then sleeved on the protective cover shell so that the rotating buckle is clamped in the rotating ring groove, and the lower end surface of the protective cover shell abuts against the upper end surface of the limiting convex ring, thereby realizing the relative rotation of the anti-theft ring sleeve, the mounting ring seat and the protective cover shell, and effectively preventing the anti-theft ring sleeve from falling off the mounting ring seat.

[0020] Preferably, a counter bushing is coaxially inserted in the protective cover shell, the lower end surface of the counter bushing abuts against the mounting ring seat, the counter bushing and the protective cover shell are circumferentially linked, the copper-sealed counter is coaxially inserted in the counter bushing, and the copper-sealed counter and the counter bushing are circumferentially linked.

[0021] By adopting the above technical solution, a counter bushing is added inside the protective cover to provide a mounting carrier for the copper-sealed counter, effectively reducing the direct contact between the copper-sealed counter and the mounting ring seat, and reducing the possibility of rotational wear of the copper-sealed counter. By rotating the protective cover, the counter bushing and the copper-sealed counter are driven to rotate together, thereby adjusting the direction of the reading on the copper-sealed counter.

[0022] Preferably, the upper inner peripheral wall of the protective cover shell has a first anti-rotation groove, and the upper protrusion of the counter bushing is fixed with a first anti-rotation block which is axially slidably inserted in the first anti-rotation groove.

[0023] By adopting the above technical solution, a first anti-rotation groove and a first anti-rotation block are added. When the counter bushing is slidably inserted into the inner cavity of the protective cover, the first anti-rotation block is slidably inserted into the first anti-rotation groove, thereby realizing the circumferential linkage setting of the counter bushing and the protective cover.

[0024] Preferably, the copper-sealed counter and the counter bushing are interference-fitted.

[0025] By adopting the above technical solution, the copper seal counter and the counter bushing are inserted into each other through interference fit, so that the relative fixation and circumferential linkage setting of the two are achieved.

[0026] In summary, the utility model has the following beneficial effects:

[0027] 1. When the reading direction of the water meter needs to be adjusted, just rotate the protective cover to drive the copper-sealed counter to rotate around its own axis to improve the convenience of reading;

[0028] 2. An elastic ring pad is added between the metering support and the anti-slip ring to effectively prevent the anti-slip ring and the metering support from having rigid contact. Under the tight force of the elastic ring pad, the metering support and the water meter housing are in a relatively fixed state;

[0029] 3. An anti-theft ring sleeve is added, which completely covers the lower part of the mounting ring seat, and the protective cover shell completely covers the upper part of the mounting ring seat, so that the mounting ring seat has a hidden structure, which effectively prevents the mounting ring seat from being disassembled and stolen.
