Description

Technical Field

[0001] This utility model belongs to the field of gas meter technology, specifically relating to an intelligent gas meter that is easy to read. Background Technology

[0002] A gas meter is a measuring instrument used to measure the volume of gas and complete trade settlements. It measures the volume of gas flowing through the pipeline, accumulates the total consumption, and displays it. Some newer gas meters also have prepaid and intelligent control functions, such as IC card top-up and LCD screen display of remaining gas volume.

[0003] In existing smart gas meters, the display screen, as a key reading component, is often designed to be quite small due to the overall size of the meter. This results in small values ​​and symbols on the screen, making it inconvenient for users and meter readers to read the data. Common solutions to this problem involve relying on external tools, such as users using magnifying glasses or meter readers taking photos with their phones and then magnifying them. However, these methods have significant drawbacks. External magnifying glasses are easily lost and inconvenient to carry, and in oily environments like kitchens, the lens easily becomes greasy, affecting subsequent use. Using mobile phone photos for magnification is greatly affected by lighting conditions; in dim light, the image clarity is insufficient, making it difficult to accurately identify values. Furthermore, the operation process is cumbersome, increasing the working time and workload of meter readers. Utility Model Content

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0018] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0019] Example Reference Figure 1-6 This is an embodiment of the present invention, which provides an intelligent gas meter that is easy to read. The gas meter body 1, The surface of the gas meter body 1 is provided with a display screen 2, and a storage box 3 is provided above the display screen 2. The storage box 3 is provided with a magnification mechanism inside. The magnifying mechanism includes a support frame 4, which is slidably installed inside the storage box 3. An optical magnifying lens 5 is installed inside the support frame 4. A pull rod 8 is installed on the side of the gas meter body 1. Connecting components are installed at both ends of the support frame 4. The top of the pull rod 8 is connected to the support frame 4 through the connecting components.

[0020] In normal use, the amplification mechanism is housed in the storage box 3 above the display screen 2. The support frame 4 and the optical magnifying lens 5 are hidden inside the box, without affecting the normal appearance of the gas meter body 1 or the basic reading function of the display screen 2. This also prevents the lens from accumulating dust and getting worn due to exposure. When the user or meter reader needs to clearly read the small values ​​on the display screen 2, the pull rod 8 on the side of the gas meter body 1 can be operated. Through the connecting components at both ends of the support frame 4, the external force of the pull rod 8 is converted into the linear movement of the support frame 4. The support frame 4 slides down along the inner wall of the storage box 3 and gradually extends out of the storage box 3. After the support frame 4 descends to the preset position, the optical magnifying lens 5 inside it just covers the core display area of ​​the display screen 2. The value is magnified through the principle of optical refraction, making the reading information clearer and easier to identify.

[0021] In summary, this device does not require external magnifying glasses, mobile phone photography, or other auxiliary tools. It can be magnified and stored simply by pushing and pulling the lever 8. This solves the problems of traditional external reading tools being easily lost and cumbersome to operate. It is especially suitable for the needs of the elderly, visually impaired people, and other groups. When not in use, the magnification mechanism can be completely stored in the storage box 3, which can effectively isolate kitchen oil and dust from contaminating the optical magnifying lens 5, while avoiding damage to the optical magnifying lens 5 caused by collisions and extending the service life of the components.

[0022] Furthermore, the connecting component includes a slider 7, which is L-shaped and fixedly installed on the top of the end face of the storage box 3. Side grooves 6 are provided at both ends of the storage box 3, and the surface of the slider 7 moves through the side grooves 6. The top of the pull rod 8 is connected to the slider 7 through a pivot.

[0023] In use, since the top of the pull rod 8 is connected to the L-shaped slider 7 through a pivot, the traction force is converted into a horizontal or vertical force on the slider 7 through the pivot. The L-shaped slider 7 is fixed to the top of the end face of the support frame 4, and its surface moves through the side grooves 6 at both ends of the storage box 3. The side grooves 6 provide a fixed sliding path for the slider 7, restricting the slider 7 to move only along the length of the side grooves 6 to avoid deviation. When the slider 7 slides in the side grooves 6, it will simultaneously drive the support frame 4 fixed to it to move. Pulling the pull rod 8 upward, the slider 7 slides upward along the side grooves 6, and the support frame 4 retracts into the storage box 3. Pulling the pull rod 8 downward, the slider 7 slides downward along the side grooves 6, and the support frame 4 extends out of the storage box 3 with the optical magnifying lens 5, thus realizing the position adjustment of the magnifying lens.

[0024] Furthermore, a torsion spring is provided at the connection between the pull rod 8 and the slide bar 7, and the torsion spring is sleeved on the surface of the rotating shaft where the pull rod 8 and the slide bar 7 are connected.

[0025] During use, under the action of the torsion spring, through the elastic restoring force, the torsion spring applies a directional torque to the pull rod 8 with the pivot as the center, forcing the pull rod 8 to maintain its initial posture perpendicular to the surface of the gas instrument body 1.

[0026] Furthermore, a button 10 is provided on the side of the gas meter body 1. The button 10 is used to switch the display information on the surface of the display screen 2. A groove 11 is provided on the surface of the pull rod 8 near the button 10. The groove 11 is connected to the button 10.

[0027] In normal use, the lever 8 is perpendicular to the surface of the gas meter body 1, and the lever 8 is not in contact with the button 10, so the button 10 is not triggered. When the operator pulls the lever 8 forward, the inclined groove 11 on the surface of the lever 8 moves synchronously with the lever 8. The inclined surface of the inclined groove 11 contacts the top of the button 10, and through the guiding effect of the inclined surface, the linear pulling force of the lever 8 is converted into a vertical pressing force on the button 10. Thus, the button 10 completes the switching of the information displayed on the surface of the display screen 2. According to the meter reading requirements, when observing the display screen 2 through the optical magnifying lens 5, the display information of the display screen 2 can be switched simply by pulling the lever 8 forward.

[0028] Furthermore, the bottom ends of the two pull rods 8 are connected to a crossbar 9, and the surface of the crossbar 9 is provided with finger grooves.

[0029] When in use, holding the crossbar 9 with one hand can simultaneously drive the movement of the two pull rods 8. The crossbar 9 serves as the fulcrum for force application, which can evenly transmit the force of the hand to the two pull rods 8, avoiding slippage and jamming caused by uneven force on one side of the pull rod 8, ensuring that the amplification mechanism extends smoothly, reducing the probability of mechanical failure. The finger groove conforms to the natural contour of the fingers, which can increase the contact area and friction between the hand and the crossbar 9.

[0030] Furthermore, a platform 12 is provided on the surface of the gas meter body 1 and below the display screen 2, and the platform 12 is located directly below the support frame 4.

[0031] When in use, when the support frame 4 extends out of the storage box 3 with the optical magnifying lens 5, its bottom will fall precisely on the drag table 12. The drag table 12 limits the maximum extension distance of the support frame 4 through physical support, ensuring that the lens is always accurately aligned with the reading area of ​​the display screen 2, and avoiding the optical magnifying lens 5 from shifting due to excessive pulling of the lever 8, which would affect the clarity of the reading.

[0032] Furthermore, an iron sheet 13 is bolted to the top of the support frame 4, and a magnetic block is provided at the top inside the storage box 3, with the magnetic block corresponding to the iron sheet 13.

[0033] When in use, when the support frame 4 is retracted into the storage box 3, the iron sheet 13 and the magnet are precisely attracted to each other, and the support frame 4 is firmly fixed to the top of the storage box 3 by magnetic force, so as to prevent the instrument from slipping or making abnormal noise due to vibration, and to ensure stable storage.
