Description

Technical Field

[0001] This application relates to the technical field of gas meters, and particularly to a gas meter. Background Art

[0002] Currently, gas is very commonly used as a general energy source. It is indispensable for ordinary household cooking, heating domestic water, and even for industrial energy. A gas meter is a measuring tool for measuring the gas usage, and it also plays a role in regulating the gas pressure in the pipeline. Due to the differences in the gas pipeline layout and installation location depending on the area where the gas meter is used or the location of the house, traditional gas meters are designed with a left meter and a right meter to meet the installation conditions. Specifically, before installing a gas meter, the gas company first needs to confirm the position of the main pipeline, that is, the intake pipeline. If the intake pipeline is on the left, a gas meter with left intake and right outlet is selected, which is simply called the left meter; otherwise, the right meter is chosen.

[0003] However, for both the left meter and the right meter, the base meter and the controller are fixedly connected together. Therefore, usually two sets of housing molds are required to meet the needs of the left and right meters, so that the display screen can be in a position convenient for people to observe. Thus, the installation method of traditional gas meters that select the left meter or the right meter according to the position of the intake pipeline has a high production cost and is difficult to meet the requirement of multi-angle observation directions, making it inconvenient to read the readings.

Detailed Description of the Invention

In the accompanying drawings, the same or similar reference numerals represent the same or similar components or components with the same or similar functions from beginning to end. The described embodiments are some, but not all, of the embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain this application and should not be construed as a limitation of this application. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of this application. The following will explain the embodiments of this application in detail with reference to the accompanying drawings.

[0038] A gas meter is a measuring tool for measuring the gas consumption and also plays a role in regulating the gas pressure in the pipeline. Due to the different regions where the gas meter is used or the locations of the houses, the gas pipeline layouts and installation positions will also vary. Therefore, traditional gas meters are set with left meters and right meters to meet the installation conditions. Specifically, before installing the gas meter, the gas company first needs to confirm the position of the main pipeline, that is, the intake pipeline. If the intake pipeline is on the left, a gas meter with left intake and right outlet is to be selected and installed, which is simply called the left meter; otherwise, the right meter is selected.

[0039] However, whether it is a left meter or a right meter, the base meter and the controller are fixedly connected together. Therefore, usually two sets of housing molds need to be opened to meet the requirements of left and right meters, so that the display screen is in a position convenient for people to observe. Therefore, the installation method of the traditional gas meter that selects a left meter or a right meter according to the position of the intake pipeline has a high production cost and is difficult to meet the requirements of multi-angle observation directions, and it is not convenient to read the readings. To solve the above technical problems, this application provides a gas meter, including: a base meter and a controller, the base meter and the controller are rotatably connected. Furthermore, the functions of both the left meter and the right meter are simultaneously satisfied through the rotatable controller. By clamping the controller base between the upper cover of the base meter and the fixed plate, the multi-angle installation and observation direction requirements of the gas meter are realized, so that the display screen is always in a position convenient for people to observe, which is convenient for reading the readings and effectively reduces the production cost.

[0040] The following introduces the solution by way of some examples.

[0041] Example 1

[0042] Figure 1 As a structural example diagram of an exemplary gas meter, as Figure 1 shown, this gas meter includes: a base meter 1 and a controller 2;

[0043] A metering channel assembly 13 is installed inside the base meter 1; the base meter 1 is provided with a first joint 122 and a second joint 123 that are communicated with the inside of the base meter 1;

[0044] A control component is installed inside the controller 2. The control component is electrically connected to the metering channel assembly 13 and is used to control the metering channel assembly 13; the base meter 1 and the controller 2 are rotatably connected.

[0045] In this example, the gas meter includes a base meter 1 and a controller 2. Among them, the base meter 1 includes a base meter upper cover 11, a base meter base 12, and a metering channel assembly 13. The base meter base 12 includes a first joint 122 and a second joint 123. Exemplarily, the first joint 122 is an intake joint, and the second joint 123 is an outlet joint. The metering channel assembly 13 is used to measure the gas throughput and thus obtain the gas consumption. The metering channel assembly 13 can be an ultrasonic metering channel assembly or other gas metering tools, and this application does not limit this.

[0046] A control component is installed inside the controller 2. The control component includes a controller upper cover assembly 21, a controller base 22, a battery cover 23, a printed circuit board (PCB board) 24, and a battery assembly 25. The metering channel assembly 13 and the valve assembly 14 are signal-connected to the controller 2. The gas consumption is measured by the metering channel assembly 13 and the data is transmitted to the controller 2 to display the reading, which not only effectively improves the metering accuracy of the gas meter but also improves the anti-interference ability of the gas meter.

[0047] The base meter 1 and the controller 2 are rotatably connected through a rotating component, and the controller 2 can be rotated 180 degrees, thereby adjusting the display screen direction according to the intake direction so that the display screen is always in a position convenient for people to observe and convenient for reading.

[0048] As an example, as Figure 1 shown, the base meter 1 includes a base meter base 12 and a base meter upper cover 11. The base meter upper cover 11 is installed on the base meter base 12. The controller 2 includes a controller base 22 and a controller upper cover assembly 21. The controller upper cover assembly 21 is installed on the controller base 22. The base meter upper cover 11 and the controller base 22 are rotatably connected.

[0049] In this example, the base meter upper cover 11 is installed on the base meter base 12. Exemplarily, the base meter upper cover 11 is snapped onto the base meter base 12 to achieve a fixed connection between the base meter upper cover 11 and the base meter base 12. Alternatively, screw holes are provided on the base meter upper cover 11, and screw holes corresponding to the screw holes on the base meter upper cover 11 are provided on the base meter base 12. Screws are passed through the screw holes of the base meter upper cover 11 and the base meter base 12 to achieve a fixed connection between the base meter upper cover 11 and the base meter base 12. The controller upper cover assembly 21 is installed on the controller base 22. The fixed connection method between the controller upper cover assembly 21 and the controller base 22 can refer to the fixed connection method between the base meter upper cover 11 and the base meter base 12. It should be noted that the foregoing fixed connection method is not limited to this. The base meter upper cover 11 and the controller base 22 can be rotatably connected, and thus, through the rotatable controller 2, multi-angle installation and viewing direction requirements can be achieved, facilitating reading, and effectively reducing production costs.

[0050] As an example, as Figure 1 shown, a display screen 222 is installed on the controller base 22;

[0051] The controller upper cover assembly 21 is provided with a transparent liquid crystal display window 211, which is arranged at a position corresponding to the display screen 222.

[0052] In this example, a display screen is installed on the controller base 22, and the controller upper cover assembly 21 is provided with a transparent liquid crystal display window 211, which is arranged at a position corresponding to the display screen 222, facilitating reading. In addition, the controller 2 realizes real-time monitoring of the state of the battery assembly 25 through the printed circuit board 24, which can ensure the stability and safety of the performance of the battery assembly 25. Moreover, since the printed circuit board 24 has electromagnetic compatibility, interference from other devices can be reduced. Further, through the cooperation working mechanism of the printed circuit board 24 and the battery assembly 25, the normal operation of the display screen 222 can be effectively guaranteed, and the probability of failure of the display screen 222 can be reduced. In addition, the base meter 1 and the controller 2 can be rotatably connected. Compared with the fixed integrated connection method, the rotatable connection method allows the controller 2 to rotate 180 degrees, and thus the direction of the display screen can be adjusted according to the intake direction, so that the display screen is always in a position convenient for people to observe, facilitating reading.

[0053] As another example, Figure 2A is a structural example diagram of a cross-sectional view of a gas meter as an example. As Figure 2A shown, the gas meter further includes: a fixing plate 261; the controller base 22 is clamped between the base meter upper cover 11 and the fixing plate 261, and the fixing plate 261 is fixedly connected to the base meter upper cover 11.

[0054] In this example, the gas meter further includes: a fixing plate 261, which can be rectangular, square, circular or other shapes. The fixing plate 261 is fixedly connected to the upper cover 11 of the base meter. The controller base 22 is clamped between the upper cover 11 of the base meter and the fixing plate 261. The fixing connection method between the fixing plate 261 and the upper cover 11 of the base meter includes but is not limited to threaded connection, bonding, welding and other methods.

[0055] As an example, the upper cover 11 of the base meter is provided with an installation part; the controller base 22 is provided with a sleeve 221;

[0056] The installation part passes through the sleeve 221 and is connected to the fixing plate 261.

[0057] In this example, the upper cover 11 of the base meter is provided with an installation part, and the controller base 22 is provided with a sleeve 221. Exemplarily, the installation part is arranged at the center of the upper cover 11 of the base meter. In order for the installation part to pass through the sleeve 221, the sleeve 221 is arranged at the position corresponding to the installation part on the controller base 22. The installation part passes through the sleeve 221 and is connected to the fixing plate 261. Exemplarily, at least one threaded hole is provided on the installation part in contact with the fixing plate 261, and a threaded through hole is opened at the position of the fixing plate 261 corresponding to the threaded hole. Align the threaded hole and the threaded through hole, and the screw 263 passes through the threaded through hole and the threaded hole for fixed connection. The type of the screw 263 is not limited, and it can be a lifting ring screw, a set screw, a pan head screw, a cylinder head screw, etc.

[0058] As an example, the installation part is a hollow tube 111;

[0059] A threaded hole is provided on the end face of one end of the hollow tube 111, and a threaded through hole is opened at the position of the fixing plate 261 corresponding to the threaded hole;

[0060] The hollow tube 111 passes through the sleeve 221 and abuts against the fixing plate 261, and the screw passes through the threaded through hole and the threaded hole of the hollow tube to fixedly connect the fixing plate 261 and the upper cover 11 of the base meter.

[0061] In this example, the installation part is a hollow tube 111, such as a round tube, etc. One end of the hollow tube 111 passes through the sleeve 221 and abuts against the fixing plate 261. At least one threaded hole is provided at the port of one end of the hollow tube 111 in contact with the fixing plate 261, and a threaded through hole is opened at the position of the fixing plate 261 corresponding to the threaded hole. Align the threaded hole and the threaded through hole, and the screw 263 passes through the threaded through hole and the threaded hole for fixed connection. The type of the screw 263 is not limited, and it can be a lifting ring screw, a set screw, a pan head screw, a cylinder head screw, etc.

[0062] As yet another example, Figure 2B Partial enlarged structural example diagram of a cross-sectional view of an exemplary gas meter, as Figure 2BAs shown, an elastic member 262 is disposed between the sleeve 221 and the fixing plate 261 in a fitting manner.

[0063] In this example, the elastic member 262 is disposed between the sleeve 221 and the fixing plate 261 in a fitting manner to the radial opening of the sleeve 221. Since it has strong thermal stability, long service life, and is not easily aged, it can well play a role in anti-slip and buffering. Exemplarily, the elastic member 262 can be a silica gel pad, a nitrile rubber pad, a fluororubber pad, etc., and the shape of the elastic member 262 can be circular, annular, etc.

[0064] As an example, as Figure 2A shown, the gas meter further includes: a wire plug-in joint assembly 15;

[0065] The control component is electrically connected to the metering channel assembly 13 and the valve assembly 14 through the wire plug-in joint assembly;

[0066] The wire plug-in joint assembly includes: a socket 151 and a fixing nut 152. One end of the socket 151 passes through the through hole at the center of the base meter upper cover 11 and is fixed within the base meter 1 by the fixing nut 152.

[0067] In this example, the control component is signal-connected to the metering channel assembly 13 and the valve assembly 14 through the wire plug-in joint assembly to control the metering channel assembly 13 and the valve assembly 14. In actual application, when the air inlet is opened, the control component controls the valve assembly 14 to open the air outlet, and the metering channel assembly 13 measures the gas usage in real time, and transmits the relevant data of the gas usage to the control component to update the displayed reading in real time; when situations such as the user being in arrears occur, the control component controls the valve assembly 14 to close the air outlet, and the control component stops updating the displayed reading and maintains the last reading data.

[0068] One end of the socket 151 passes through the through hole at the center of the base meter upper cover 11 and is fixed within the base meter 1 by the fixing nut 152. The control component realizes signal connection with the metering channel assembly 13 and the valve assembly 14 through the socket 151.

[0069] As another example, Figure 3A and Figure 3B are respectively structural example diagrams of a gas meter of an example. As Figure 3A and Figure 3B shown, a base cavity 121 is formed within the base meter base 12; the base meter 1 further includes: a mounting plate 124; a valve assembly 14 is also installed within the base meter;

[0070] The mounting plate 124 is installed within the base meter base 12 to divide the base cavity 121 into a first chamber 1211 and a second chamber 1212; the mounting plate 124 is provided with air through holes, and the first chamber 1211 and the second chamber 1212 are communicated through the air through holes;

[0071] The metering channel assembly 13 is located in the first chamber 1211, and the valve assembly 14 is located in the second chamber 1212.

[0072] In this example, the valve assembly 14 is installed inside the base meter. Exemplarily, the first joint 122 is an air inlet joint, the second joint 123 is an air outlet joint, and the air outlet of the valve assembly 14 is installed at the second joint 123 to control the opening and closing of the second joint 123. The metering channel assembly 13 and the valve assembly 14 are signal-connected to the controller 2. The gas consumption is measured through the metering channel assembly 13 and the data is transmitted to the controller 2 for displaying the reading, which not only effectively improves the metering accuracy of the gas meter, but also improves the anti-interference ability of the gas meter.

[0073] The mounting plate 124 is limited and installed through the limiting groove of the base cavity 121, separating the base cavity 121 into a first chamber 1211 and a second chamber 1212. The first chamber 1211 and the second chamber 1212 are communicated through the air holes on the mounting plate 124. Exemplarily, the first joint 122 is an air inlet joint, the second joint 123 is an air outlet joint, the first chamber 1211 is an air inlet chamber, the second chamber 1212 is an air outlet chamber, the volume of the first chamber 1211 is larger than that of the second chamber 1212, and the mounting plate 124 is arranged close to the second chamber 1212. In addition, the mounting plate 124 can also be connected to the base meter 12 by welding, bonding, clamping and screwing.

[0074] In addition, the metering channel assembly 13 is fixed to the mounting plate 124 by a buckle. It should be noted that the installation method of the metering channel assembly 13 and the mounting plate 124 is not limited in this application.

[0075] The first chamber 1211 is an air inlet chamber, the second chamber 1212 is an air outlet chamber, the metering channel assembly 13 is located in the air inlet chamber, and the valve assembly 14 is located in the air outlet chamber. It can be seen that the first joint 122, the metering channel assembly 13, the valve assembly 14, other components inside the base meter 1 and the second joint 123 are arranged in a "one" character sequence. The whole base meter 1 is symmetric up and down and left and right, and can meet different installation angles.

[0076] As another example, Figure 4 is a structural example diagram of a gas meter as an example, as Figure 4 shown, the base meter 12 adopts a symmetric structure.

[0077] In this example, a first joint 122 and a second joint 123 communicating with the base cavity 121 are respectively arranged at both ends of the base meter 1. The controller 2 and the base meter 1 are rotatably connected. The base of the base meter 12 adopts a symmetrical structure, and the entire base meter 1 is symmetrical up and down and left and right. The controller 2 can be installed by rotating 180 degrees, enabling multi-angle installation, and the controller 2 can be rotated according to the intake direction to adjust the direction of the display screen 222, so that the display screen 222 is always in a position convenient for users to observe and convenient for reading.

[0078] For the gas meter provided in this embodiment, the base meter and the controller are rotatably connected. Among them, the base meter is provided with a first joint and a second joint communicating with the inside of the base meter; a control component is installed in the controller, and the control component is electrically connected to the metering channel assembly for controlling the metering channel assembly; the base meter and the controller are rotatably connected. That is to say, for the gas meter in this example, the base meter and the controller are rotatably connected, and thus the multi-angle installation and observation direction requirements of the gas meter can be realized through the rotatable controller, which is convenient for reading, and effectively reduces the production cost.
