Description

Technical Field

[0001] The utility model discloses a water meter case, in particular to a portable water meter case. Background Art

[0002] A water meter is an instrument that measures water flow, mostly the cumulative flow of water. It is generally divided into two categories: volumetric water meters and velocity water meters. The former is more accurate than the latter, but has high requirements for water quality and is easily blocked when there are impurities in the water. The meter that records the amount of tap water is installed on the water pipe. When the user drains the water, the pointer or wheel on the meter rotates to indicate the amount of water passing through.

[0003] In the prior art, the water meter is assembled by a water meter case and an upper water meter cover. Water flows into the water meter case through an inlet, passes through the water meter by the water flow rate to achieve a metering effect, and is discharged along the outlet. At the same time, an isolation member in the water meter case is used to prevent water from flowing back along the water inlet. Secondly, the water meters in the prior art are not necessarily all used in places with good water quality, which will still cause some water meter cases to be blocked. Secondly, the water meter case in the prior art is generally formed by stretching both sides in half and then welding. After setting, if the water meter case is blocked, it is not easy to clean. Therefore, a new solution is proposed. Utility Model Content

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. In the description of the utility model, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, which are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] A convenient water meter housing, such as Figure 1-Figure 4 As shown, it includes a water meter housing 1, a fixing member 2 is threadedly connected to the bottom of the water meter housing 1, a pressing member 3 is slidably connected to the fixing member 2, a closing block 4 abutting against the fixing member 2 is arranged on one end of the pressing member 3 located in the water meter housing 1, a groove 5 for accommodating the closing block 4 to be embedded is arranged on the fixing member 2, a drain port 6 which is misaligned with the closing block 4 and accommodates the outflow of water and impurities is arranged in the pressing member 3, a scraping member 7 which is spaced apart from the closing block 4 is arranged on the inner side of the pressing member 3, and the scraping member 7 is higher than the closing block 4 and abuts against the fixing member 2. After using this device, it can be used for a long time in places with poor water quality and more impurities. If the inside is clogged with impurities and a large number of impurities are deposited at the bottom, the pressing piece 3 is pressed inwardly and the closing block 4 and the scraper 7 are moved upward at the same time. The closing block 4 is disengaged from the groove 5 and the scraper 7 is moved upward and disengaged from the groove and abuts against the bottom surface of the water meter housing 1. The pressing piece 3 is rotated so that the drain port 6 on the pressing piece 3 is connected to the groove 5. At the same time, the scraper 7 can scrape off the impurities adhered to the bottom of the water meter housing 1 when it rotates, and push it to the position close to the groove 5. The water flow is turned on to drive water and impurities to flow directly into the drain port 6 along the groove 5, thereby achieving the effect of cleaning.

[0020] The closing block 4 has magnetic force and is adsorbed with the groove 5. The fixing part 2 is provided with a magnetic block 8 at the scraper 7. The magnetic block 8 repels the magnetic force of the closing block 4. The pressing part 3 is provided with a protrusion 9 embedded in the fixing part 2. The fixing part 2 is provided with a limiting groove 10 for accommodating the protrusion 9 to be embedded. Secondly, under normal use, the closing block 4 and the groove 5 are adsorbed with magnetic force, and because of the restrictions of the protrusion 9 and the limiting groove 10, the effect of fixing the pressing part 3 is achieved. Therefore, when the water inlet is opened, the pressing part 3 can be prevented from being washed away by the water flow and moving up.

[0021] The bottom of the limiting groove 10 is connected to an arc groove 11 for accommodating the movement of the protrusion 9. The end of the arc groove 11 away from the limiting block is connected to a slot 12. The slot 12 is higher than the arc groove 11. When pressing, the pressing member 3 is pushed upward, so that the protrusion 9 moves up along the bottom of the limiting groove 10 and enters the arc groove 11. At the same time, when the protrusion 9 is rotated so as to be embedded in the arc groove 11, the closing block 4 is opposite to the magnetic block 8. Because the magnetic block 8 and the closing block 4 are magnetically repelled, they are pushed upward by the magnetic block 8, so that the closing block 4 and the pressing member 3 move up, and the protrusion 9 is embedded in the slot 12. In this state, the closing block 4 will not abut against the magnetic block 8, and the drain port 6 moves up, so that the water flow can better enter the drain port 6 and impurities can be better discharged. Secondly, after stretching and forming, the bottom is opened and the above-mentioned device is installed, so that it is convenient to clean the internal impurities, avoiding the need to disassemble the cover for cleaning as in the prior art.

[0022] The water meter housing 1 includes an upper part 14 and a lower part 15, and the upper part 14 and the lower part 15 are both formed as one piece by stretching, and the upper part 14 and the lower part 15 are welded. Compared with the half-stretching forming and welding in the prior art, this forming method takes less time and has a shorter weld length. At the same time, the welding technology content of the half-welded state is high and more troublesome, while the one-piece tubular ring welding of the present application is easier and more convenient, which saves costs and shortens the welding time. Moreover, the upper part 14 and the lower part 15 are stretched and formed, and the forming is faster and more convenient. At the same time, the middle isolation part is convenient for welding. Compared with the prior art that uses adhesives or pastes or other methods for adhesion, and heating forming, the above-mentioned setting facilitates welding and forming, saves processing time, and thus reduces costs. The water meter housing 1 is provided with support members 13 on both sides of the upper part 14, and the support members 13 are slidably connected to the upper part 14. At the same time, the support members 13 facilitate the fixing of the water meter housing 1 to the outside, and are slidably connected to ensure that the support members 13 can be moved at will. At the same time, according to different usage scenarios, the fixed position is different, so that the support member 13 can be moved to achieve a fixing effect.
