Description

Technical Field

[0001] This utility model relates to the field of gas concealed box technology, specifically a gas concealed box for a water heater. Background Technology

[0002] In the field of gas pipeline installation engineering, to achieve aesthetic appeal and optimize space utilization, concealed gas pipeline installation has become one of the mainstream design methods for gas systems in residential and commercial buildings. Among these components, the concealed gas pipe box, as a core accessory, is primarily used to house and protect the valves at the ends of the concealed pipeline. This ensures that the valves, while fulfilling their gas on / off control functions, are protected from external damage or environmental corrosion due to exposure, and also facilitates future inspection and maintenance of the valves. In the actual installation process of gas pipe concealed boxes, it is necessary to first cut grooves in the wall according to the preset size of the concealed box, then embed the concealed box into the groove and fix it, and then install the valve and connect it to the gas pipe. However, there are significant technical pain points in the current construction process: due to the differences in the materials of different building walls (such as brick walls, concrete walls, lightweight partition walls, etc.), and the fact that on-site construction personnel usually rely on experience to judge the groove depth, there is a lack of standardized depth positioning and control methods, which easily leads to a mismatch between the wall groove depth and the height of the concealed box. When the groove depth is too deep, the embedded box will sink as a whole after being embedded in the wall. This will cause the reference surface for installing the valve inside the embedded box to be lower than the wall surface. This will cause the valve joint inside the embedded box to sink and shift towards the side closer to the wall. This sinking will cause the axis of the valve joint to deviate from the axis of the metal gas pipe to be connected, and the joint extension length will be insufficient, making it difficult to achieve precise connection between the metal gas pipe and the valve. Summary of the Invention

[0003] Based on this, the purpose of this utility model is to provide a gas-sealed box for water heaters to solve the technical problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a gas concealed box for a water heater, comprising a concealed box, an adjustable connecting plate, a two-way pipe, a flared pipe, a connecting piece, and a valve; Adjustable connecting plates are installed at all four corners of the concealed box. The adjustable connecting plates have long grooves for passing bolts through them. By adjusting the position of the adjustable connecting plates along the length of the long grooves, it can adapt to installation scenarios where the groove depth is greater than the thickness of the concealed box. The four sets of adjustable connecting plates are symmetrically distributed to form a balanced clamping and fixing force on the concealed box, so as to prevent the concealed box from sinking, shifting or shaking after installation. The bottom of the concealed box is equipped with a two-way pipe. The two-way pipe is connected to the concealed box by a mounting plate and screws to realize gas input and transmission. The two-way pipe includes a mounting plate, a gas input port and a first connecting port. The two-way pipe is connected to the concealed box by a mounting plate and screws. One end of the two-way pipe is provided with a gas inlet and the other end is provided with a first connection port. The gas inlet is connected to the gas pipeline pre-embedded in the wall. The flared pipe is inserted into the back of the concealed box and is used for the gas pipeline pre-embedded in the wall to pass through, so as to prevent the concrete filling the trench from entering the concealed box and affecting the two pipes. The inner diameter of the flared pipe is larger than the outer diameter of the gas pipeline, and the diameter of the flared pipe at the end closer to the concealed box is larger than the diameter at the end farther away from the concealed box, so as to facilitate the passage of the gas pipeline and enhance the sealing of the insertion with the concealed box. The buried box has a plug groove on one side that matches the flared pipe, so that the flared pipe can be stably inserted into the plug groove from the back of the buried box to achieve connection, thereby preventing the concrete filling the groove from entering the buried box and avoiding the concrete from affecting the assembly and use of the two pipes inside the buried box. The bottom of the concealed box is fixed with a connecting piece. The connecting piece has two sets of connecting holes. The connecting holes are matched with the mounting plate of the two-way pipe to achieve stable assembly of the two-way pipe. The connecting pieces are set in multiple sets and can be replaced and assembled at the bottom of the concealed box. The spacing between the two sets of connecting holes on the multiple sets of connecting pieces is different to adapt to the different installation position requirements of the two-way pipe and expand the applicability of the device. The valve is detachably connected to the two-way pipe, and the valve can be connected to the water heater through a metal gas pipe to control the supply of gas to the water heater. The valve includes a second connecting pipe port and a gas output pipe port. The valve has a second connecting pipe port that is threadedly connected to the first connecting pipe port at one end, and a gas output pipe port at the other end. The gas output pipe port is connected to the water heater through a metal gas pipe. It also includes a cover plate and a decorative cover. The cover plate is fitted to the open end of the buried box to protect the two-way pipes and valves inside the buried box. The decorative cover is fitted to the outside of the cover plate to optimize the appearance of the device and improve its aesthetic coordination with the wall.

[0005] In summary, the present invention has the following main advantages: 1. This utility model uses adjustable connecting plates with long grooves at the four corners of the concealed box. It eliminates the need for strict matching of groove depth and concealed box thickness. Even if the groove is too deep, stable installation can be achieved by adjusting the position of the connecting plate, avoiding secondary grooving or wall repair, reducing construction time and material waste, and reducing reliance on the experience of construction personnel, thus improving construction efficiency. The back of the concealed box is fitted with a flared pipe through a plug groove, which can isolate the concrete filling the groove when the gas pipeline is installed, preventing concrete from entering the box and affecting components such as the two-way pipe. The two-way pipe is fixed by a connecting piece with different hole spacing, which can adapt to different installation requirements and ensure the stability of its connection position with the valve, avoiding gas transmission failure due to component displacement. 2. The cover plate of this utility model can provide physical protection for the two-way pipe and valve inside the buried box, reducing the corrosion of dust and impurities. The decorative cover on the outside can optimize the appearance of the device, making it consistent with the style of the wall, taking into account both practicality and aesthetics. The valve and the two-way pipe are detachably connected, and the cover plate and decorative cover are easy to install and remove. When it is necessary to inspect or replace internal components in the future, there is no need to disassemble the fixed structure between the buried box and the wall, which greatly reduces the difficulty of maintenance and ensures the long-term stable operation of the gas system.

[0008] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0009] The embodiments of this utility model will be described below based on its overall structure.

[0010] Example 1 Figure 1-3As shown, the gas concealed box for the water heater in this embodiment includes a concealed box 1, an adjustable connecting plate 2, a two-way pipe 4, a flared pipe 6, a connecting piece 7, a valve 8, a cover plate 9, and a decorative cover 10. These components work together to achieve stable installation, gas transmission control, and protective decoration functions for the concealed box. The specific component relationships are as follows: The buried box 1 serves as the core housing carrier. It has four corners reserved for assembly positions to install adjustable connecting plates 2. One side has a plug groove 5 adapted to the flared tube 6. The bottom is fixed with a connecting piece 7 for positioning the two-way tube 4. The open end can be covered with a cover plate 9. The adjustable connecting plate 2 has a long groove 3 for bolts to pass through to connect the embedded box 1 to the wall; The two-way pipe 4 is connected to the bottom of the buried box 1 through its own mounting plate. One end is used to connect to the pre-buried gas pipeline, and the other end is connected to the valve 8. The flared pipe 6 is inserted into the insertion slot 5 of the buried box 1 for the gas pipeline to pass through; The decorative cover 10 is fitted to the outside of the cover plate 9 to improve the appearance coordination between the lifting device and the wall. Installation of concealed box 1 in relation to the wall: Based on the overall dimensions of the concealed box 1, a groove is cut at the preset position in the wall. If the groove depth is greater than the thickness of the concealed box 1, there is no need to make secondary adjustments to the groove. The four sets of adjustable connecting plates 2 are respectively bolted to the reserved positions at the four corners of the concealed box 1, and then the concealed box 1 is placed into the groove.

[0011] By adjusting the position of the adjustable connecting plate 2 along the length of the long groove 3, the adjustable connecting plate 2 is adapted to the wall connection points on both sides of the groove. Then, the bolts are passed through the long groove 3 to fix the adjustable connecting plate 2 and the buried box 1. The four sets of symmetrically distributed adjustable connecting plates 2 form a balanced clamping force to ensure that the buried box 1 is stably fixed in the groove, avoiding sinking, displacement or shaking.

[0012] Assembly of flared pipe 6 with gas pipeline: Insert the flared pipe 6 into the insertion slot 5 from the back of the concealed box 1, so that the flared pipe 6 and the concealed box 1 form a stable insertion structure. Then, pass one end of the gas pipe pre-embedded in the wall through the flared pipe 6 and extend it into the interior of the concealed box 1. Use the flared pipe 6 to isolate the concrete that will be filled into the slot later, so as to prevent the concrete from entering the interior of the concealed box 1 and affecting the assembly of subsequent components.

[0013] Assembly of the two-way pipe 4 and valve 8: According to the hole distribution of the mounting plate of the two-way pipe 4, select the corresponding hole spacing of the connecting piece 7 (if it is necessary to adapt to the two-way pipe 4 with different hole positions, the connecting piece 7 with different hole spacing can be directly replaced). Fix the mounting plate 401 of the two-way pipe 4 to the connecting piece 7 with screws so that the two-way pipe 4 is stably assembled in the bottom of the concealed box 1.

[0014] Connect the end of the two-way pipe 4 near the flared pipe 6 to the pre-buried gas pipeline to build the gas input channel; then detachably connect one end of the valve 8 to the end of the two-way pipe 4 away from the gas pipeline to complete the assembly of the on / off control structure for the gas transmission path.

[0015] Assembly of protective and decorative components: After the two-way pipe 4 and valve 8 inside the concealed box 1 are assembled, the cover plate 9 is fitted onto the open end of the concealed box 1 to provide physical protection for the internal components and prevent dust and impurities from entering. Finally, the decorative cover 10 is fastened onto the outside of the cover plate 9 to make the appearance of the device consistent with the wall and complete the overall assembly.

[0016] The working principle of this utility model is as follows: When in use, a groove is cut in the wall according to the size of the buried box 1, and the size of the groove is consistent with the size of the buried box 1. Meanwhile, the depth of the groove can be greater than the thickness of the concealed box 1. At this time, the concealed box 1 and the wall are connected by the adjustable connecting plates 2 at the four corners of the concealed box 1. Specifically, the adjustable connecting plates 2 are provided with long grooves 3 for passing bolts. By adjusting the distance of the adjustable connecting plates 2, even if the groove depth is greater than the thickness of the concealed box 1, the concealed box 1 can be stably connected to the walls on both sides of the groove by the four sets of adjustable connecting plates 2. In summary, the adjustable connecting plate 2, as a key connecting component between the concealed box 1 and the wall, plays a crucial role in breaking the strict limitation on the groove depth of traditional concealed box installation. When the groove depth exceeds the thickness of the concealed box 1 during construction, there is no need to readjust the groove depth (avoiding damage to the wall structure and delays in the construction period due to secondary construction). By adjusting the adjustable connecting plates 2 at the four corners of the concealed box 1, a precise fit and connection between the concealed box 1 and the wall can be achieved. This solves the industry pain point of "installation difficulties caused by mismatch between groove depth and concealed box thickness" from the structural design level. The long groove 3 on the adjustable connecting plate 2 provides adjustable installation space for the bolts. According to the actual depth of the groove and the relative position of the buried box 1, the construction personnel can flexibly adjust the connection distance between the adjustable connecting plate 2, the buried box 1, and the wall along the length of the long groove 3. This adjustment capability can not only compensate for the size difference caused by the excessive groove depth, but also fine adjust the horizontal and vertical position of the buried box 1 in the groove, ensuring that the buried box 1 remains horizontal and upright after final installation, avoiding the deviation of the subsequent valve joint and gas pipe connection due to position offset, and laying the foundation for the accuracy of valve installation. Four sets of adjustable connecting plates 2 are respectively set at the four corners of the buried box 1, forming a symmetrical and balanced force structure. When the groove depth is greater than the thickness of the buried box 1, the four sets of connecting plates can apply stable clamping and fixing force to the buried box 1 from the walls on both sides of the groove by inserting bolts in the long groove 3 and tightening them. This avoids problems such as "sinking", "shifting" or "shaking" of the buried box 1 due to the groove being too deep, and ensures that the buried box 1 always maintains a stable connection with the wall during long-term use, eliminating safety hazards such as valve joint displacement and gas pipeline deformation caused by the loosening of the buried box. A two-way pipe 4 is installed inside the concealed box 1. The two-way pipe 4 is installed to the bottom of the concealed box 1 with screws through the mounting plate 401. The gas input port 402 is connected to the gas pipeline pre-embedded in the wall for gas input. The gas pipeline passes through the flared pipe 6. Then, the first connecting pipe port 403 is threadedly connected to the second connecting pipe port 801 of the valve 8, and the gas output pipe port 802 of the valve 8 is connected to the water heater through a metal gas pipe, so that the gas can be delivered to the water heater for use. Furthermore, when the traditional flared pipe 6 and the buried box 1 are connected to each other, one end of the flared pipe 6 is often inserted into the inside of the buried box 1 from the open end of the buried box 1. With this connection method, when the buried box 1 is installed inside the trench, the inside of the trench will be filled with a certain amount of concrete. As a result, when the buried box 1 is installed inside the trench, the concrete will enter the inside of the buried box 1 to a certain extent, which will affect the two pipes 4. The flared pipe 6 of this application is inserted into the back of the buried box 1 and connected to it. In other words, the concrete filled in the back of the buried box 1 will not affect the interior of the buried box 1, thus avoiding the impact on the two-way pipe 4. A connecting piece 7 is fixed at the bottom of the concealed box 1. The two sets of connecting holes on the connecting piece 7 correspond to the two sets of connecting holes on the mounting plate 401, so that the two pipes 4 can be stably connected. By replacing the connecting piece 7, the spacing between the two sets of connecting holes on different connecting pieces 7 is different, thereby adapting to the installation position of different mounting plates 401, and the application range is relatively wide.
