Description

Technical Field

[0001] This utility model belongs to the field of gas meters, specifically relating to a universal protective bracket for the LCD screen of the main control circuit board of a gas meter. Background Technology

[0002] In the production process of gas meters, the LCD screen is usually directly soldered onto the main control circuit board. However, this soldering method has the problem of difficulty in controlling the distance between the LCD screen and the main control circuit board, and during transportation, gas meters are easily bumped and damaged, causing the LCD screen to collide with the casing and be squeezed, resulting in the pins tilting. To solve these problems, LCD screen protective brackets are usually used to support the LCD screen. Most existing LCD screen protective brackets adopt a platform structure, with a large platform directly supporting the LCD screen. This structure means that different models of LCD screens require different models of brackets, which not only increases mold costs but also complicates material management and increases costs. At the same time, the large platform structure leads to a large amount of material waste, increasing costs. Utility Model Content

[0003] In view of the problems existing in the prior art, the purpose of this utility model is to provide a technical solution for a universal protective bracket for the LCD screen of the main control circuit board of a gas meter.

[0004] The aforementioned universal protective bracket for the LCD screen of a gas meter main control circuit board is characterized in that the bracket consists of four identical structural components. The upper part of each component is configured as a platform structure with enclosures on two adjacent sides. The four structural components are respectively located at the four corners of the LCD screen, with the inner side of the enclosures facing the LCD screen, for supporting and enclosing the LCD screen. The lower part of each component is provided with elastic barbed buckles, which engage with pre-drilled holes on the main control circuit board to install the structural components onto the main control circuit board.

[0005] The aforementioned universal protective bracket for the LCD screen of the main control circuit board of a gas meter is characterized in that the structural components are made of plastic.

[0006] The aforementioned universal protective bracket for the LCD screen of the main control circuit board of a gas meter is characterized in that the structural component is a hollow structure with a wall thickness of 1.5-1.8mm and a regular thickness.

[0007] The aforementioned universal protective bracket for the LCD screen of the main control circuit board of a gas meter is characterized in that the upper enclosure of the structural component is higher than the plane of the LCD screen, thereby limiting the peripheral movement of the LCD screen.

[0008] This utility model has the following beneficial effects:

[0009] 1. These four identical plastic structural parts can be used for positioning and support of LCD screens of different sizes, avoiding frequent mold opening due to differences in LCD screen size and significantly reducing costs;

[0010] 2. This bracket can be used for every type of LCD product, effectively reducing the types of materials, lowering material costs, and simplifying production and management processes;

[0011] 3. The LCD screen is supported and positioned using only four structural components, eliminating the need for materials in the middle of the existing large platform structure and significantly reducing costs;

[0012] 4. During transportation, it can effectively protect the LCD screen and prevent damage such as pin tilting caused by collisions, thus improving the reliability and stability of the product. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] This utility model provides a universal protective bracket for the LCD screen of the main control circuit board of a gas meter, aiming to solve the problems of difficult installation and positioning of the LCD screen, easy damage during transportation, and the increased cost due to the variety of brackets caused by different LCD screen sizes.

[0020] This utility model discloses a universal protective bracket for the LCD screen of the main control circuit board of a gas meter. It consists of four identical structural components 2, each made of plastic. The structural components 2 are hollow with a wall thickness of 1.5-1.8mm, ensuring consistent thickness and effectively reducing cooling deformation. The upper part of each structural component 2 is designed as a platform with baffles 4 on two adjacent sides to support the LCD screen 1. The four structural components 2 are positioned at the four corners of the LCD screen 1 to support and enclose it. The inner side of the baffles 4 of each structural component 2 faces the LCD screen 1, and the upper baffles 4 are slightly higher than the LCD screen plane, thus limiting the peripheral movement of the LCD screen. When the gas meter's plastic casing is impacted, the force is distributed to the structural components of the protective bracket, effectively avoiding direct impact on the LCD screen and protecting it. The lower part of each structural component 2 is equipped with an elastic hook buckle 5, which engages with pre-drilled holes 6 on the main control circuit board 3 to ensure stable and accurate installation.

[0021] Because the upper part of the structural component has a platform structure with barriers on two adjacent sides, and the platform structure has a certain area, if the LCD screen has different models and sizes, it can be installed as long as it can be supported on the platform. During use, it can achieve the functions of support and protection, thereby reducing the cost of opening different molds for different models of LCDs in the existing technology. At the same time, the four structural components are independent of each other, and there is no need for a large platform to support the LCD screen, which also greatly reduces the use of materials and lowers the material cost of the protective bracket.

[0022] Specific installation method:

[0023] 1. With the inner side of the enclosure 4 of the structural component 2 facing the direction of the LCD screen 1, press the elastic barb buckles 5 at the bottom of the four structural components into the four reserved holes 6 on the main control circuit board 3. When you hear a "click", it means that the elastic barb buckles 5 of the structural component have been installed in place.

[0024] 2. Gently shake the four structural components 2 to ensure there is no wobbling;

[0025] 3. Pass the pins of LCD screen 1 through the pin holes 7 of the main control circuit board 3, so that the LCD screen is placed flat on the four structural components;

[0026] 4. Turn the main control circuit board 3 upside down and solder the LCD screen pins on the back with a soldering iron to ensure a firm solder joint.
