Description

Technical Field

[0001] This utility model relates to the field of water meter technology, specifically to a water meter cover that is easy to disassemble. Background Technology

[0002] The water meter cover is an important component of the water meter, mainly serving to protect the internal components of the water meter (especially the dial of the base meter), prevent external environmental influences, and facilitate reading and maintenance.

[0003] The cover of existing smart water meters with magnetoresistive sensors is typically hinged to the meter housing on one side, allowing it to rotate up and down for opening and closing. However, when the water meter and its cover are installed in a confined space or among multiple water meters arranged vertically, the vertical opening space of the cover is limited, preventing complete opening to observe the meter's data and hindering disassembly of the housing and cover. Furthermore, while smart water meter covers typically have a gap near the magnetoresistive sensor for easy opening, a large gap can prevent the cover from completely covering the meter's dial, leading to dust or water seepage and hindering accurate meter readings. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model provides a water meter cover that is easy to disassemble.

[0005] The technical solution of this utility model is as follows:

[0006] A water meter cover that is easy to disassemble is installed on the water meter housing. The housing has a magnetic resistance placement shell for placing a magnetic resistance element. The cover includes a cover body and two sets of sliding units symmetrically arranged on its two inner sides. The two sets of sliding units are located on both sides of the magnetic resistance placement shell.

[0007] The sliding unit includes a sliding bar. The upper surface of the watch case is provided with a sliding groove that is adapted to the sliding bar. The length of the sliding bar is shorter than the length of the sliding groove. The end of the sliding groove away from the magnetic resistance housing is open. The sliding bar slides along the length of the sliding groove. The sliding groove includes a sliding groove and a locking groove that are connected vertically. The lower part of the sliding bar is locked into the locking groove. The sliding bar can move along its height direction within the sliding groove.

[0008] The water meter is installed along the length of the water pipe it connects to. This allows for ample space for opening and disassembly along the length of the pipe. Therefore, a sliding strip is provided on the inner lower end of the meter casing. This strip slides into a groove in the casing, allowing the casing to move horizontally when opened or closed. This design makes efficient use of the space along the length of the water pipe, making it particularly suitable for situations where multiple water meters are installed vertically where vertical space is limited. Furthermore, the side of the meter cover closest to the magnetic resistance housing does not require a pre-existing gap, reducing the amount of dust or moisture entering the meter's dial surface and affecting the readings.

[0009] The specific structure of the sliding groove is as follows: the sliding groove is set as an inverted T-shaped groove, and the snap-fit ​​groove is opened on the bottom surface of the T-shaped groove. The snap-fit ​​groove is a V-shaped groove, and the width of the upper opening of the snap-fit ​​groove is smaller than the width of the bottom surface of the T-shaped groove. The lower part of the sliding bar can snap into the V-shaped groove after the watch cover is placed in the preset position on the watch case, so as to realize the installation and fixation of the watch cover on the watch case, and reduce the entry of dust or moisture into the surface of the dial inside the watch case through the edge of the watch cover.

[0010] The T-slot structure is as follows: the T-slot includes a vertically connected vertical slot and a horizontal slot. The lower part of the slide bar is symmetrically provided with baffles on both sides along its width direction. The baffles slide in the horizontal slot. The end of the baffle away from the slide bar extends to the side of the horizontal slot. The baffles can prevent the slide bar from leaving the slot when it moves in the vertical direction.

[0011] The baffle is installed such that the vertical distance from the bottom surface of the baffle to the lowest point of the sliding bar is the same as the height of the V-groove.

[0012] When checking the water meter dial, to prevent the sliding bar from dislodging from the sliding groove when moving along the length of the sliding groove, making it inconvenient to reinstall the meter cover, a stop component is detachably provided at the end of the sliding groove away from the magnetic resistance placement shell. The stop component is located in the transverse groove and includes a stop plate. An anti-dislodgement plate is provided at the end of the sliding bar near the magnetic resistance placement shell, located in the transverse groove. The anti-dislodgement plate is set correspondingly to the stop plate.

[0013] The structure of the aforementioned stop assembly is as follows: the stop assembly also includes a connector, and the stop plate is connected to the watch case through the connector.

[0014] The beneficial effects of this utility model are as follows:

[0015] The meter casing and cover are installed on the water meter, which is installed on the water pipe. For multi-user wells, multiple water meters are installed vertically, and the vertical operating space is small, while the space along the water pipe is larger. Therefore, the cover is connected to the casing through sliding units on both sides. The lower inner side of the casing has a sliding strip that can slide into the sliding groove opened in the casing. The cover can slide onto the casing along the direction of the adjacent water pipe, making it easy to open the casing and check the meter reading.

[0016] The cover is close to the side with the magnetic reluctance housing, so there is no need to leave a large gap between it and the magnetic reluctance housing. This reduces the phenomenon that dust or moisture can enter the dial surface of the water meter through the cover and affect the dial reading.

[0017] The lower part of the sliding bar can be engaged in the V-groove after the cover is placed in the preset position on the watch case, so as to fix the cover on the watch case and reduce dust or moisture from entering the dial surface inside the watch case through the edge of the cover.

[0018] When opening or removing the watch cover, in order to enable the baffle to move up and down a certain distance so that the lower part of the slide bar is disengaged from the V-groove, and the slide bar does not disengage from the slide groove in the up and down direction, the ratio of the height of the horizontal groove to the height of the baffle is set to 4-5. This allows the baffle on the slide bar to move up a certain height when the watch cover is opened, and then the watch cover can move outward along the length of the slide groove to open.

[0031] See Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a water meter cover that is easy to disassemble is installed on the water meter housing 1. The housing 1 has a magnetic resistance placement shell 11 for placing magnetic resistance components. The cover 2 includes a cover body and two sets of sliding units symmetrically arranged on its two inner sides. The side of the cover body near the magnetic resistance placement shell 11 is adapted to the outer surface of the magnetic resistance placement shell 11. One side of the cover body can be in close contact with the adjacent surface of the magnetic resistance placement shell 11. The two sets of sliding units are located on both sides of the magnetic resistance placement shell 11.

[0032] See Figure 7 , Figure 8 and Figure 9 As shown, the sliding unit includes a sliding bar 4. The upper surface of the case 1 is provided with a sliding groove 3 that is adapted to the sliding bar 4. The length of the sliding bar 4 is shorter than the length of the sliding groove 3. The end of the sliding groove 3 away from the magnetic resistance placement shell 11 is open. The sliding bar 4 slides along the length direction of the sliding groove 3. The sliding groove 3 includes a sliding groove 31 and a locking groove 32 that are connected vertically. The lower part of the sliding bar 4 is locked and connected to the locking groove 32. The sliding bar 4 can move along its height direction within the sliding groove 3.

[0033] The specific structure of the sliding groove 31 is as follows: the sliding groove 31 is set as an inverted T-shaped groove, the snap-fit ​​groove is opened on the bottom surface of the T-shaped groove, the snap-fit ​​groove is a V-shaped groove, the lower part of the sliding bar 4 is adapted to the V-shaped groove, the lower part of the sliding bar 4 is a V-shaped tip, the width of the upper opening of the snap-fit ​​groove is smaller than the width of the bottom surface of the T-shaped groove, and the lower part of the sliding bar 4 can snap into the V-shaped groove after the cover 2 is placed on the watch case 1 in a preset position, so as to realize the installation and fixation of the cover 2 on the watch case 1, and reduce dust or moisture from entering the surface of the dial inside the watch case 1 through the edge of the cover 2.

[0034] See Figure 2 , Figure 5 and Figure 6 As shown, the T-slot structure includes a vertically connected vertical slot 311 and a horizontal slot 312. Symmetrical baffles 5 are provided on both sides of the lower part of the sliding bar 4 along its width direction. The baffles 5 slide within the horizontal slot 312, with one end of the baffle 5 away from the sliding bar 4 extending towards the side of the horizontal slot 312. The baffles 5 prevent the sliding bar 4 from detaching from the slot 3 when moving vertically. The baffles 5 are installed such that the vertical distance from the bottom surface of the baffle 5 to the lowest point of the sliding bar 4 is the same as the height of the V-slot.

[0035] When opening or removing the watch cover 2, in order to enable the baffle 5 to move up and down a certain distance so that the lower part of the slide bar 4 is disengaged from the V-groove, and the slide bar 4 is not disengaged from the slide groove 3 in the up and down direction, when the watch cover 2 is opened, the baffle 5 on the slide bar 4 can move up a certain height in the transverse groove 312 so that the lower part of the slide bar 4 is disengaged from the V-groove, and the watch cover 2 can move outward along the length direction of the slide groove 3 to open.

[0036] The water meter in this embodiment is installed along the length of the water pipe to which it is connected. There is a large space for opening and disassembly along the length of the water pipe. For this purpose, a sliding strip 4 is provided on the inner side of the lower end of the meter housing 1. The sliding strip 4 can slide into the sliding groove 3 opened in the meter housing 1, so that the meter housing 1 can move horizontally when opening or closing. This can make reasonable use of the space along the length of the water pipe, which is especially suitable for multiple water meters installed vertically where the vertical space is small. In addition, the side of the meter cover 2 close to the magnetic resistance placement shell 11 does not need to leave a gap with the magnetic resistance placement shell 11, reducing the amount of dust or water vapor entering the dial surface of the water meter through the meter cover 2 and affecting the dial reading.

[0037] See Figure 2 and Figure 6 As shown, when checking the water meter dial, to prevent the sliding bar 4 from disengaging from the sliding groove 3 while moving along its length, thus avoiding inconvenience in reinstalling the meter cover 2 or reducing the number of times the meter cover 2 needs to be reinstalled on the meter housing 1, a stop assembly is detachably provided at the end of the sliding groove 3 away from the magnetic resistance placement housing 11. The stop assembly is located within the transverse groove 312 and includes a stop plate 6. An anti-disengagement plate 7 is provided at the end of the sliding bar 4 near the magnetic resistance placement housing 11, located within the transverse groove 312. The anti-disengagement plate 7 corresponds to the stop plate 6. The stop assembly also includes a connector 8, through which the stop plate 6 is connected to the meter housing 1.
