Description

Technical Field

[0001] This utility model belongs to the field of gas meter technology, specifically relating to a mounting bracket and a camera-based direct-reading gas meter reading device. Background Technology

[0002] A gas meter is a precision instrument used to measure gas consumption. Its core metering mechanism drives a dial or pointer through mechanical transmission, thus displaying the cumulative gas consumption. Traditional gas meter readings mainly rely on manual on-site meter reading, which suffers from low efficiency, high labor costs, susceptibility to reading errors, and inability to achieve real-time data monitoring. With the development of the Internet of Things and smart cities, remote automatic meter reading has become the mainstream trend in the field of gas metering.

[0003] To achieve automatic identification and remote transmission of gas meter readings, current technologies typically employ camera devices for automatic reading and transmission. The basic principle is as follows: a miniature camera is fixed near the gas meter dial. This camera periodically captures images of the display dial or pointer area, then automatically analyzes the reading information from the images using image processing algorithms, and finally uploads the data to the monitoring center via a communication module. Currently, the installation of camera devices mainly includes the following methods: 1. Binding fixation: Using flexible components such as cable ties or ropes to bind the camera device to the gas meter body or gas inlet / outlet pipes. While simple and easy to implement, the binding components are prone to loosening or breakage due to vibration or aging, causing the camera device to shift or fall off, resulting in a deviated shooting angle and inaccurate capture of the meter image, leading to reading recognition failure. 2. Threaded locking fixation: Threaded holes need to be specially drilled in the gas meter casing or outer cover, and the camera device is locked onto them using screws. While this method offers high connection strength, it requires drilling and modification of the gas meter itself. This is not only cumbersome and inefficient, but more seriously, it damages the original sealing and structural strength of the gas meter casing, potentially introducing safety hazards and affecting the validity of the meter's original metering certification. Adhesive fixing: This method uses double-sided tape or strong adhesives to attach the camera device to the gas meter's glass cover or body. Although this method is non-invasive, the reliability of the bond is greatly affected by environmental factors such as temperature, humidity, oil, and dust. Over time, the adhesive may fail, causing the camera device to loosen and fall off; furthermore, if the bonding position deviates, readjustment is extremely inconvenient, and residual adhesive residue affects the aesthetics. Therefore, existing installation methods for direct-reading gas meter cameras generally suffer from unreliable connections that are prone to loosening, cumbersome and inefficient installation procedures, invasive damage or risk of damage to the gas meter itself, and poor overall aesthetics.

[0033] To facilitate understanding of this utility model, the specific embodiments of this utility model will be described in more detail below with reference to the accompanying drawings.

[0034] Unless otherwise specified or defined, the terms "first," "second," etc., used in this document are for distinguishing names only and do not represent a specific number or order.

[0035] Unless otherwise stated or defined, the term “and / or” as used herein includes any and all combinations of one or more of the associated listed items.

[0036] It should be noted that in this article, "fixed to" or "connected to" can mean directly fixed to or connected to a component, or indirectly fixed to or connected to a component.

[0037] The present invention will be described below with reference to specific embodiments.

[0038] Example 1

[0039] This utility model embodiment provides a mounting bracket 10, such as Figures 1 to 3 As shown, the mounting bracket 10, used to assemble the camera device onto the gas meter 20, includes a frame 1, a first snap-fit ​​component 2, and a second snap-fit ​​component 3.

[0040] The frame 1 has a first end and a second end that are arranged opposite to each other. The frame 1 has a insertion groove 11 for inserting and frictionally engaging with a gas meter 20 at the position corresponding to the first end. The second end of the frame 1 forms an open structure 12 that communicates with the insertion groove 11. The first end of the frame 1 is provided with a first snap-fit ​​member 2 for snapping with the gas meter 20, and the second end of the frame 1 is provided with a second snap-fit ​​member 3 for snapping with a camera device.

[0041] Specifically, the mounting bracket 10 can fix the camera device to the gas meter 20. When it is necessary to fix the camera device to the gas meter 20, first align the insertion slot 11 of the bracket 1 with the gas meter 20, apply a pushing force to make the end of the gas meter 20 with the reading dial slide into and be accommodated in the insertion slot 11, and make the reading dial of the gas meter 20 face the open structure 12 at the second end of the bracket 1. By forming an interference fit or tight fit between the inner side wall of the insertion slot 11 and the outer side wall of the gas meter 20, sufficient friction force is generated to form a friction fit, effectively preventing loosening between the two. At the same time, the structure of the gas meter 20 being clamped by the first snap-fit ​​2 realizes the quick connection and fixation between the bracket 1 and the gas meter 20 without tools or fasteners. After the bracket 1 is fixed to the gas meter 20, fix the camera device to the second end of the bracket 1, and make the camera of the camera device face the open structure 12 of the bracket 1. Then, fix the camera device to the bracket 1 through the second snap-fit ​​3. When it is necessary to replace or maintain the camera device, simply remove it from the second clip 3 or remove the entire frame 1 from the gas meter 20. This operation will not cause damage or residue to the gas meter 20 itself, making it convenient for later maintenance.

[0042] In summary, this embodiment, through the installation bracket 10, wherein the bracket body 1 is provided with a plug-in slot 11, allows the bracket body 1 to be plugged into and frictionally fastened to the gas meter 20. That is, the bracket body 1 and the gas meter 20 form a tight connection through frictional engagement. Combined with the clamping engagement structure between the first snap-fit ​​member 2 and the gas meter 20, and the clamping engagement structure between the second snap-fit ​​member 3 and the camera device, the camera device can be directly fixed and accurately positioned on the gas meter 20. This allows the camera device to accurately capture the reading of the gas meter 20 and identify the reading. Furthermore, it eliminates the need for additional fasteners such as ropes, adhesives, and screws for fixation. It features convenient installation, easy disassembly, reliable connection, and no structural damage, while also improving aesthetics.

[0043] In some embodiments, the second latching member 3 includes a fixing plate 31 and at least one latching body 32. The fixing plate 31 is vertically disposed at the second end of the frame 1. The latching body 32 includes a first latching plate 321 and a second latching plate 322. The first end of the first latching plate 321 is connected to the frame 1 and extends outward along the plane of the second end of the frame 1. The second latching plate 322 is connected to the second end of the first latching plate 321 and extends towards the first end of the frame 1. Specifically, the first latching plate 321 and the second latching plate 322 cooperate to form an inverted L-shaped structure. It should be noted that the camera device has a housing, which has a corresponding insertion hole corresponding to the position of the fixing plate 31, and a latching block corresponding to the position of the latching body 32, which is adapted to the latching body 32 and is hook-shaped. When it is necessary to assemble the camera device onto the frame 1, first insert the socket of the camera device housing into the fixing plate 31 for initial fixation and positioning. Then, adjust the position of the camera device so that the camera of the camera device is aligned with the reading dial of the gas meter 20. Then, apply external force to the camera device and press the camera device so that the locking block on the housing is hooked and engaged with the second locking plate 322 for mechanical interlocking and fixation. This fixes the camera device and effectively prevents it from falling off due to gravity or vibration.

[0044] In some embodiments, the frame 1 includes an enclosure plate 13, which includes a first enclosure plate 131 and a second enclosure plate 132; both the first enclosure plate 131 and the second enclosure plate 132 are annular structures; the second enclosure plate 132 is mounted on top of the first enclosure plate 131, and the annular spaces within the first enclosure plate 131 and the second enclosure plate 132 are interconnected to form the insertion slot 11; the fixing plate 31 and the snap-fit ​​body 32 are both disposed on the second enclosure plate 132, and the top of the second enclosure plate 132 forms the open structure 12. It should be noted that since there are two main types of existing gas meters 20, the mounting bracket 10 of this utility model also has two variations. This embodiment refers to the structure of the first type of gas meter 20, such as... Figure 1 As shown, the first enclosure 131 and the second enclosure 132, through their cooperation, can adapt to the shape of the gas meter 20. The first enclosure 131 surrounds the lower outer peripheral wall of the gas meter 20, and the second enclosure 132 surrounds the upper outer peripheral wall of the gas meter 20. The shapes of the first enclosure 131 and the second enclosure 132 are set differently to adapt to the shape of the gas meter 20. Specifically, in this embodiment, the radial area of ​​the annular space of the second enclosure 132 is smaller than the radial area of ​​the annular space of the first enclosure 131, so that the inner wall of the insertion groove 11 forms a stepped groove structure. This allows the enclosure plate 13 to be tightly attached to the outer peripheral wall of the gas meter 20, thereby increasing the contact area between the two, further improving the friction between them, and improving the connection stability. It should be noted that both the first enclosure 131 and the second enclosure 132 are square enclosure structures, which are suitable for the structure of the square gas meter 20 and facilitate precise positioning.

[0045] In some embodiments, such as Figures 1 to 3 As shown, the second enclosure 132 has a through hole 1321 that connects to the insertion slot 11 on the side of the fixed plate 31 and the snap-fit ​​body 32. That is, the second enclosure 132 has a hollow structure around its perimeter. On the one hand, this makes the structure lighter and reduces the overall weight of the frame 1, avoiding potential structural stability problems caused by the excessive weight of the mounting bracket 10, and also facilitates heat dissipation. On the other hand, it makes it easier for the user to apply force when assembling the camera device onto the frame 1.

[0046] In some embodiments, the first latching member 2 includes a third latching plate 21 and a fourth latching plate 22; the third latching plate 21 is connected to the first enclosure plate 131 and extends outward along the radial direction of the first enclosure plate 131; the fourth latching plate 22 is connected to the third latching plate 21 and extends in a direction away from the second enclosure plate 132; and a protrusion 221 is provided at one end of the fourth latching plate 22 away from the third latching plate 21. Specifically, the third card plate 21 and the fourth card plate 22 cooperate to form an inverted L-shaped structure. It should be noted that since the gas meter 20 does not have a slot 202 structure, but a protruding ring 201 is provided on the gas meter 20 adjacent to the reading meter, this embodiment forms the inverted L-shaped first carding member 2 on the side of the first enclosure 131 away from the second enclosure 132. When the frame 1 is inserted into the gas meter 20, the fourth card plate 22 of the first carding member 2 elastically abuts against the side wall of the protruding ring 201, thereby providing frictional force to resist minor daily vibrations. This effectively ensures that the frame 1 will not loosen or shift under normal use conditions, ensuring the long-term accuracy of the camera's viewing angle. Furthermore, the setting of the protrusion 221 of the fourth card plate 22 can effectively limit the frame 1 from sliding upward or outward relative to the protruding ring 201, thus strengthening the fixation.

[0047] In some embodiments, one or more snap-fit ​​bodies 32 may be provided, depending on the actual fixing needs, and no particular limitation is made here. Specifically, in this embodiment, one snap-fit ​​body 32 is provided, which is located on the side of the second enclosure 132 adjacent to the fixing plate 31. The second enclosure 132 and the snap-fit ​​body 32 have a snap-fit ​​opening 1322 on the opposite side, and the second enclosure 132 has an inclined surface 1323 above the snap-fit ​​opening 1322. It should be noted that a hook is also provided on the side of the camera device housing opposite to the snap-fit ​​block. The snap-fit ​​body 32 is adapted to the snap-fit ​​block of the camera device housing, and the snap-fit ​​opening 1322 is equipped with the hook of the camera device housing. The inclined surface 1323 above the snap-fit ​​opening 1322 facilitates the snap-fit ​​hook of the camera device to engage with the snap-fit ​​opening 1322 for fixing.

[0048] This utility model embodiment also provides a camera-based direct-reading gas meter reading device, which includes a gas meter 20, a camera device, and a mounting bracket 10 as described above; the gas meter 20 is detachably connected to the mounting bracket 10, and when the gas meter 20 is connected to the mounting bracket 10, the insertion slot 11 is inserted into and frictionally engaged with the gas meter 20, and the first snap-fit ​​member 2 is snapped into the gas meter 20; the camera device is detachably connected to the mounting bracket 10, and when the camera device is connected to the mounting bracket 10, the second snap-fit ​​member 3 is snapped into the camera device. Understandably, this camera-based direct-reading gas meter reading device, through the installation bracket 10, which has a plug-in slot 11 on the bracket body 1, allows the bracket body 1 to be plugged into and frictionally fastened to the gas meter 20. That is, the bracket body 1 and the gas meter 20 form a tight connection through frictional engagement. Combined with the clamping engagement structure between the first snap-fit ​​part 2 and the gas meter 20, and the clamping engagement structure between the second snap-fit ​​part 3 and the camera device, the camera device can be directly fixed and accurately positioned on the gas meter 20. This allows the camera device to accurately capture the reading dial of the gas meter 20 for identification and reading, without the need for additional fasteners such as ropes, adhesives, or screws. It features convenient installation, easy disassembly, reliable connection, and no structural damage, while also improving aesthetics.

[0049] Example 2

[0050] The difference between the mounting bracket 10 in this embodiment and the embodiment 1 is that the specific structures of the frame 1 and the second snap-fit ​​member 3 are different. Otherwise, it is the same as in embodiment 1.

[0051] Specifically, such as Figures 4 to 5 As shown, the frame 1 includes an enclosure plate 13, multiple support columns 14, and multiple mounting plates 15. The enclosure plate 13 has a ring-shaped structure, and the mounting plates 15 are supported on the enclosure plate 13 by the support columns 14. The space between the enclosure plate 13, the support columns 14, and the mounting plates 15 forms the insertion groove 11. The mounting plates 15 are provided with the open structure 12. It should be noted that this embodiment is for the structure of the second type of gas meter 20, such as... Figure 4As shown, the structure of the enclosure plate 13, support columns 14, and mounting plate 15 can adapt to the shape of the gas meter 20. The enclosure plate 13 surrounds the outer peripheral wall below the gas meter 20. Four support columns 14 are provided, located around the top of the gas meter 20. The mounting plate 15 is a hollow annular plate structure, with the hollow area forming the open structure 12, which facilitates the camera device to read the value of the gas meter 20. Furthermore, the support columns 14 not only ensure a stable connection between the mounting plate 15 and the enclosure plate 13, but also make the structure lightweight, reducing the overall weight of the frame 1 and avoiding potential structural stability problems caused by excessive weight of the mounting bracket 10. They also facilitate heat dissipation and make it easier for the user to apply force when assembling the camera device onto the frame 1.

[0052] In some embodiments, such as Figure 5 As shown, the first latching member 2 includes a third latching plate 21 and a fourth latching plate 22. The third latching plate 21 is connected to the enclosing plate 13 and extends along the extension direction of the enclosing plate 13 towards the side away from the mounting plate 15. The fourth latching plate 22 is connected to the third latching plate 21 and extends towards the inner space of the enclosing plate 13. It should be noted that the enclosing plate 13 forms a clearance structure corresponding to the position of the first latching member 2, thereby facilitating the installation of the third latching plate 21 and the fourth latching plate 22 and their fixed engagement with the gas meter 20. Specifically, the third latching plate 21 and the fourth latching plate 22 cooperate to form an inwardly bent inverted L-shaped structure. It should be noted that since the gas meter 20 is provided with a slot 202 at its edge, after the gas meter 20 is inserted into the frame 1, the frame 1 can be fixedly connected by the first snap-fit ​​part 2 snapping into the slot 202 of the gas meter 20. The operation is simple and convenient.

[0053] In some embodiments, two first latching members 2 are provided, and the two first latching members 2 are arranged symmetrically with respect to the enclosure plate 13. The two first latching members 2 cooperate to make the frame 1 securely fixed to the gas meter 20 and facilitate disassembly. Of course, in other embodiments, the number of first latching members 2 is not limited to two; other numbers such as one, three, four, five, etc. are also possible, and the specific setting can be made according to actual needs. No special limitation is made here.

[0054] In some embodiments, two snap-fit ​​bodies 32 are provided, and the two snap-fit ​​bodies 32 are disposed on opposite sides of the second end of the frame 1. The two snap-fit ​​bodies 32 cooperate to fix the camera device, which can securely fix the camera device to the gas meter 20 as a whole, and facilitates disassembly.

[0055] The above embodiments are not an exhaustive list based on the present invention, and there may be other embodiments not listed. Any substitutions and improvements made without departing from the concept of the present invention are within the protection scope of the present invention.
