Description

Technical Field

[0001] This utility model relates to the field of gas meter technology, specifically to a diaphragm gas meter. Background Technology

[0002] A gas meter is a device used to measure and record the amount of gas (such as natural gas, liquefied petroleum gas, etc.) used. Gas meters can accurately measure the amount of gas used by users, providing a basis for gas companies to charge, and also allowing users to clearly understand their gas usage, so as to make rational use of gas resources and save gas.

[0003] A diaphragm gas meter is a gas metering device widely used in homes and businesses. It measures gas volume flow by the reciprocating motion of a diaphragm. The diaphragm gas meter uses a flexible diaphragm metering chamber to measure gas volume flow. Under the action of pressure difference, gas enters the metering chamber alternately through the distribution valve, and after filling, it is discharged to the gas outlet. At the same time, it drives the flexible diaphragm in the metering chamber to reciprocate. The conversion mechanism converts this filling and discharging cycle into the corresponding gas volume flow, and then transmits it to the counter through the transmission mechanism to complete the gas accumulation metering function.

[0004] Existing diaphragm gas meters are installed solely through pipelines, which is not conducive to supporting the meter itself. Over time, the meter's own weight and the limited lifespan of its components can affect the lifespan of the connection between the meter and the pipeline, thus hindering its usability. Therefore, there is an urgent need to design a new type of diaphragm gas meter to address these issues. Utility Model Content

[0005] The purpose of this invention is to provide a diaphragm gas meter to address the aforementioned shortcomings of the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A diaphragm gas meter includes a diaphragm gas meter body. Fixed blocks are fixed at both ends of the middle portion of one side surface of the diaphragm gas meter body. A rotating block is rotatably mounted between the opposite surfaces of the fixed blocks. A connecting block is fixed to the side surface of the rotating block away from the diaphragm gas meter body. A movable block is fixed to the side surface of the connecting block away from the rotating block. A screw is threaded vertically into the middle portion of the movable block, the screw being vertical and penetrating the upper and lower surfaces of the middle portion of the movable block. A mounting plate is rotatably mounted on the lower end of the screw.

[0008] Preferably, a first rotating rod is fixed to the middle of both ends of the rotating block. The first rotating rod is horizontal and passes through both ends of the middle of the corresponding fixed block. The outer ring surface of the first rotating rod is rotatably connected to the middle of the corresponding fixed block through a bearing.

[0009] Preferably, a third rotating rod is fixed to the lower end surface of the screw, the third rotating rod passes through the upper and lower surfaces of the middle part of the mounting plate, and the outer ring surface of the third rotating rod is rotatably connected to the middle part of the mounting plate through a bearing.

[0010] Preferably, a fixing plate is rotatably mounted on the upper end of the screw, and a second rotating rod is fixed to the upper end of the screw. The second rotating rod passes through the upper and lower surfaces of the middle part of the fixing plate, and the outer ring surface of the second rotating rod is rotatably connected to the middle part of the fixing plate through a bearing.

[0011] Preferably, a limiting rod is fixed at the middle of both ends of the lower surface of the fixed plate, the limiting rod is in a vertical state, and the limiting rod passes through the upper and lower surfaces of the moving block at the corresponding positions.

[0012] Preferably, the movable block has a matching limiting hole corresponding to the limiting rod, and the lower end of the limiting rod is fixedly connected to the corresponding position on the upper surface of the mounting plate.

[0013] Preferably, a rotating disk is fixed to the upper surface of the second rotating rod, and a plurality of protrusions are fixed at intervals along the circumferential direction on the outer ring surface of the rotating disk.

[0014] Preferably, bolts are threaded into the four corners of the mounting plate in a vertical direction, and the bolts are all vertical and penetrate the upper and lower surfaces of the mounting plate at the corresponding positions.

[0015] In the above technical solution, the diaphragm gas meter provided by this utility model has the following beneficial effects:

[0016] (1) In this utility model, after the diaphragm gas meter body is installed with the external pipeline, it helps to support the diaphragm gas meter body itself. After long-term use of the diaphragm gas meter body, it can avoid the diaphragm gas meter body's own weight and usage time from affecting the service life of the connection between the diaphragm gas meter body and the pipeline, so as to facilitate the use of the diaphragm gas meter body.

[0017] (2) In this utility model, when the rotating disk rotates, it can drive the screw to rotate through the second rotating rod. When the screw rotates, it will drive the third rotating rod to rotate along the mounting plate. The second rotating rod and the third rotating rod can limit the screw, so as to make the screw rotate stably. When the screw rotates, it will cause the threaded moving block to move in the vertical direction.

[0018] (3) In this utility model, the protrusion can prevent slipping on the outer ring surface of the rotating disk, which facilitates the stable rotation of the rotating disk. When the moving block moves in the vertical direction, it will move in the vertical direction along the outside of the limiting rod through the limiting hole. The limiting rod can limit the moving block through the limiting hole, which facilitates the stable movement of the moving block. Attached Figure Description

[0026] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0027] like Figure 1-5As shown in the figure, the present invention provides a diaphragm gas meter, including a diaphragm gas meter body 1. Fixed blocks 2 are fixed at both ends of the middle part of one side surface of the diaphragm gas meter body 1. A rotating block 3 is rotatably installed between the opposite surfaces of the fixed blocks 2. A connecting block 7 is fixed on the side surface of the rotating block 3 away from the diaphragm gas meter body 1. A moving block 8 is fixed on the side surface of the connecting block 7 away from the rotating block 3. A screw 12 is threaded into the middle part of the moving block 8 in the vertical direction. The screw 12 is vertical and passes through the upper and lower surfaces of the middle part of the moving block 8. An mounting plate 9 is rotatably installed at the lower end of the screw 12.

[0028] In this embodiment, a rotating block 3 is mounted on the opposite surfaces of the fixed block 2 so that they can rotate together.

[0029] Specifically, a first rotating rod 4 is fixed to the middle of both ends of the rotating block 3. The first rotating rod 4 is in a horizontal state and passes through both ends of the middle of the corresponding fixed block 2. The outer ring surface of the first rotating rod 4 is rotatably connected to the middle of the corresponding fixed block 2 through bearings. The fixed block 2 can limit the first rotating rod 4.

[0030] In this embodiment, a screw rod 12 is threaded into the middle of the movable block 8 along the vertical direction.

[0031] Specifically, a third rotating rod 6 is fixed to the lower end surface of the screw 12. The third rotating rod 6 passes through the upper and lower surfaces of the middle part of the mounting plate 9. The outer ring surface of the third rotating rod 6 is rotatably connected to the middle part of the mounting plate 9 through a bearing. The mounting plate 9 can limit the movement of the third rotating rod 6.

[0032] Specifically, a fixing plate 10 is rotatably mounted on the upper end of the screw 12, and a second rotating rod 5 is fixed on the upper end of the screw 12. The second rotating rod 5 passes through the upper and lower surfaces of the middle part of the fixing plate 10. The outer ring surface of the second rotating rod 5 is rotatably connected to the middle part of the fixing plate 10 through a bearing. The fixing plate 10 helps to limit the movement of the second rotating rod 5.

[0033] Specifically, a limiting rod 11 is fixed at the middle of both ends of the lower surface of the fixed plate 10. The limiting rods 11 are all in a vertical state and pass through the upper and lower surfaces of the corresponding positions on the moving block 8. The limiting rods 11 can fix and limit the fixed plate 10.

[0034] Specifically, the movable block 8 has a matching limiting hole 16 corresponding to the limiting rod 11. The lower end of the limiting rod 11 is fixedly connected to the corresponding position on the upper surface of the mounting plate 9. The limiting rod 11 and the limiting hole 16 help to limit the movable block 8, making it easier to move the movable block 8 stably.

[0035] Specifically, a rotating disk 14 is fixed to the upper surface of the second rotating rod 5. Several protrusions 15 are fixed at intervals along the circumferential direction on the outer ring surface of the rotating disk 14. The protrusions 15 can prevent slippage on the outer ring surface of the rotating disk 14, making it easy to rotate the rotating disk 14 stably.

[0036] Specifically, bolts 13 are threaded into the four corners of the mounting plate 9 in a vertical direction. The bolts 13 are all vertical and pass through the upper and lower surfaces of the corresponding positions on the mounting plate 9. The bolts 13 can install and limit the mounting plate 9, which helps to ensure stable use of the mounting plate 9.

[0037] Working steps: 1. Align the lower surface of the mounting plate 9 with the external installation location, ensuring that the lower surface of the mounting plate 9 and the external installation location are in a matching and fitting state. Install the mounting plate 9 with the external installation location using bolts 13. Bolts 13 can fix and limit the mounting plate 9. The mounting plate 9 can support and limit the various components assembled on the mounting plate 9, which helps to stably use the various components assembled on the mounting plate 9, so as to facilitate the stable use of this diaphragm gas meter.

[0038] 2. When the installation height of the main body 1 of this diaphragm gas meter needs to be adjusted, the rotating disk 14 is rotated by the protrusion 15. The protrusion 15 can prevent slippage on the outer ring surface of the rotating disk 14, which facilitates the stable rotation of the rotating disk 14. When the rotating disk 14 rotates, it can drive the screw 12 to rotate through the second rotating rod 5. When the screw 12 rotates, it will drive the third rotating rod 6 to rotate along the mounting plate 9. The second rotating rod 5 and the third rotating rod 6 can limit the screw 12, which facilitates the stable rotation of the screw 12. When the screw 12 rotates, it will cause the threaded moving block 8 to move in the vertical direction. When the moving block 8 moves in the vertical direction, it will move in the vertical direction along the outside of the limiting rod 11 through the limiting hole 16. The limiting rod 11 can limit the moving block 8 through the limiting hole 16, which facilitates the stable movement of the moving block 8.

[0039] Third, when the movable block 8 moves vertically, it can drive the diaphragm gas meter body 1 to move vertically through the connecting block 7, rotating block 3, first rotating rod 4 and fixed block 2, so as to adjust the installation height of the diaphragm gas meter body 1. When it is necessary to adjust the installation angle of the diaphragm gas meter body 1, the diaphragm gas meter body 1 is rotated, so that the diaphragm gas meter body 1 drives the fixed block 2 to rotate along the first rotating rod 4, so as to rotate the part of the diaphragm gas meter body 1 used for installation with the external pipeline to correspond to the position of the external pipeline, so as to facilitate the installation between the diaphragm gas meter body 1 and the external pipeline. In use, the various components in this application can support the diaphragm gas meter body 1, so as to stably use the diaphragm gas meter body 1.
