Description

Technical Field

[0001] This utility model relates to the field of gas equipment technology, specifically a semi-open flip-top gas outlet box. Background Technology

[0002] Against the backdrop of accelerated global energy structure adjustment, natural gas, with its advantages of being clean, efficient, and relatively low-carbon, has become an important part of the energy transition in various countries. With the introduction of the "dual carbon" target, my country is also continuously promoting the optimization of its energy consumption structure. The proportion of natural gas in primary energy consumption is constantly increasing, and more and more households and industrial and commercial places are choosing to use gas as their main energy source for cooking, heating, power generation, etc. This has led to a rapid growth trend in both the scope and amount of gas used.

[0003] Currently, gas installation in the market is mainly divided into two types: exposed installation and concealed installation. In the exposed gas pipe method, some users directly expose the gas pipes and valves, relying only on some cabinets for concealment. Other users use exposed boxes that are directly fixed to the wall, which can only accommodate a few pipe joints, but are exposed overall, failing to meet the aesthetic requirements of home decoration. Therefore, the concealed gas installation method has emerged, embedding the concealed box into the wall groove, which can hide most of the pipes and valves. The common design is mostly a fixed panel with a reserved valve operation hole. This type of product balances aesthetics and basic protection functions to a certain extent and has become the mainstream choice for concealed installation.

[0004] However, while existing surface-mounted gas distribution boxes offer convenient maintenance, the exposed pipes and valves not only affect the aesthetics of the interior design but also make them susceptible to damage from the external environment. In traditional concealed boxes, some products completely enclose the valves and pipes inside the box to achieve concealment, requiring the entire box to be disassembled or the wall to be damaged during maintenance, which is cumbersome and costly. Others, while reserving space for valve operation, leave the valves and other components exposed, failing to achieve a perfect concealment effect. Exposed valves are also prone to dust accumulation or accidental activation, making it difficult to balance aesthetics, safety, and ease of maintenance. Therefore, a semi-open flip-top gas outlet box is proposed. Summary of the Invention

[0005] Therefore, the purpose of this utility model is to provide a semi-open flip-top gas outlet box to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a semi-open flip-top gas outlet box, comprising a box body, slots at both ends of the box body, and connecting blocks fixedly installed through the slots. A plug plate adapted to the slot is fixedly connected to one end of the connecting block near the box body, and the connecting block is inserted into the end of the box body from bottom to top through the plug plate for tool-free installation. A through hole is provided in the middle of the connecting block for passing a gas pipe through. A valve is provided inside the box body, and an adjusting rod is fixedly installed on one side of the valve for daily valve adjustment. A limit component is fixedly installed inside the box body for fixing the position of the gas pipe. A cover is detachably connected to the top of the box body, and a panel is fixedly installed at one end of the top of the cover, while a movable plate is rotatably installed at the other end.

[0007] By adopting the above technical solution, the movable plate can be flexibly rotated around the rotation axis, and the rotation angle can meet the maintenance needs. During daily use, closing the movable plate can cover the internal structure of the box to prevent dust from entering. When maintenance is required, it can be opened without disassembling the cover, thus balancing protection and maintenance convenience. The edges of all components of the installed wall outlet box are flush, ensuring that the equipment is flat and coordinated with the wall to match the home decoration style, while also taking into account the operation feel and reliability of use, thus comprehensively improving the overall performance of the gas wall outlet box.

[0008] Furthermore, the limiting component includes a fixing plate and a metal pressure plate, wherein the fixing plate is fixedly installed at the bottom of the box, and the metal pressure plate is fixedly installed inside the box and locked to the fixing plate.

[0009] By adopting the above technical solution, the fixing plate and the metal pressure plate form a double fixing structure with upper and lower clamping. Compared with a single fixing component, it can apply stable constraint force to the gas pipeline from different dimensions and avoid pipeline displacement due to uneven force.

[0010] Furthermore, a positioning shaft is rotatably mounted on the side of the panel near the movable plate, and the panel and the movable plate are connected to each other through the positioning shaft.

[0011] By adopting the above technical solution, the positioning pivot connection ensures that the movable plate is always associated with the panel. When opening the movable plate, there is no need to find the alignment position, and when closing it, it can be accurately aligned with the edge of the panel, improving the smoothness of operation.

[0012] Furthermore, a knob is fixedly installed at the top of the adjusting rod, and the top of the adjusting rod protrudes from the top of the panel.

[0013] By adopting the above technical solution, and through the cooperation of the adjustment rod and the knob, users can accurately adjust the gas without opening the cover in daily life.

[0014] Furthermore, the surface of the box is provided with multiple sets of raised strips, and the top of the box corresponds to the bottom of the cover.

[0015] By adopting the above technical solution, the corresponding convex strips and the bottom structure of the cover can form a mechanical engagement. When installing the cover, there is no need to repeatedly adjust the position of the cover. Simply align the groove at the bottom of the cover with the convex strip of the box to quickly complete the initial positioning, which greatly shortens the installation time. It is especially suitable for non-professionals and reduces the difficulty of alignment.

[0016] Furthermore, a support strip is fixedly connected to the bottom of the cover, and the support strip has a U-shaped design, with both sides of the support strip fitting against the inner wall of the box.

[0017] By adopting the above technical solution, the U-shaped design gives the support strip a natural elastic buffering performance. When the cover is inserted into the box, the U-shaped structure can deform slightly to adapt to the small dimensional errors of the inner wall of the box. After installation, it elastically resets to form a tight fit. Compared with straight support strips, it can better adapt to the differences in installation accuracy of the box after different wall grooves, and improve assembly adaptability.

[0018] In summary, the present invention has the following main advantages: This utility model utilizes a bottom-up interlocking design between the connecting block and the box body, employing bidirectional extrusion and pushing forces to offset splicing gaps and prevent loosening of the connecting block. Combined with an arc-shaped metal pressure plate for integrated locking of the pipes and valves, it disperses clamping forces to prevent box deformation and mitigates the risk of displacement caused by equipment vibration and external force contact, ensuring long-term stability of the pipe interfaces. In terms of ease of operation, tool-free assembly is achieved through the interlocking of the cover's protruding strips, the elastic fixing of the U-shaped support strips, and the pressing and snapping installation of the panel. The valves and movable plates can be directly controlled via knobs for inspection and maintenance, simplifying daily use and maintenance. Furthermore, the edges of all components of the installed wall-mounted box are flush, ensuring a smooth and harmonious fit with the wall surface to match home décor, while also considering ease of operation and reliability, comprehensively improving the overall performance of the gas wall-mounted box.

[0021] 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.

[0022] The embodiments of this utility model will be described below based on its overall structure.

[0023] Example 1: A semi-open flip-top gas outlet box, such as... Figure 1-8 As shown, the device includes a box body 1 with slots 12 at both ends. A connecting block 4 is fixedly installed through these slots 12. A fitting insert plate 41, compatible with the slot 12, is fixedly connected to the end of the connecting block 4 closest to the box body 1. The thickness of the insert plate 41 precisely matches the depth of the slot 12, preventing lateral misalignment of the connecting block 4 after installation and ensuring its proper position. There are no noticeable gaps after insertion. The connecting block 4 is inserted into the end of the box body 1 from bottom to top via the insert plate 41, allowing for tool-free installation. No screwdrivers, wrenches, or other tools are needed; installation can be completed by hand, significantly lowering the installation threshold and making it particularly suitable for non-professionals. A through hole is provided in the middle of the connecting block 4 for passing a gas pipe, providing auxiliary positioning and preventing pipe misalignment during installation. A rubber pad can be attached to the inner wall of the through hole to reduce friction and wear between the pipe and the connecting block 4 during pipe vibration, extending the pipe's lifespan. A valve 2 is installed inside the box body 1, and an adjusting rod 21 is fixedly installed on one side of the valve 2. The valve 2 is used for daily adjustment. The length of the adjusting rod 21 is adapted to the thickness of the box body 1 and the cover 3. The user can control the opening and closing of the valve 2 without touching the valve body, avoiding the inconvenience of directly reaching into the box body 1. A limit component is fixedly installed inside the box body 1 to fix the position of the gas pipeline. The limit component can fit tightly against the outer wall of the pipeline, which will not damage the pipeline and can limit the lateral and longitudinal displacement of the pipeline, offsetting the risk of pipeline loosening caused by equipment vibration or external force, and ensuring the airtightness of the pipeline interface. The top of the box body 1 is detachably connected to the cover 3. A panel 31 is fixedly installed on one end of the top of the cover 3, and a movable plate 33 is rotatably installed on the other end. The movable plate 33 can be flexibly flipped around the rotation axis. The flipping angle can meet the maintenance needs. When in daily use, closing the movable plate 33 can cover the internal structure of the box body 1, improve the overall aesthetics, and prevent dust from entering. When maintenance is required, it can be opened without disassembling the cover 3, which combines protection and maintenance convenience.

[0024] Please see Figure 1-8 The limiting component includes a fixing plate 13 and a metal pressure plate 14. The fixing plate 13 and the metal pressure plate 14 form a double fixing structure with upper and lower clamping. Compared with a single fixing component, it can apply stable constraint force to the gas pipeline from different dimensions, avoiding pipeline displacement due to uneven force. The fixing plate 13 is fixedly installed at the bottom of the box 1, and the metal pressure plate 14 is fixedly installed inside the box 1. The metal pressure plate 14 is designed with an arc-shaped structure. The inner side of the arc can closely fit the outer wall of the gas pipeline, increasing the contact area with the pipeline. This not only avoids excessive local pressure damaging the pipeline, but also improves clamping stability and prevents pipeline slippage. It is also locked to the fixing plate 13. The metal pressure plate 14 and the fixing plate 13 are locked by pins or screws, which enhances the versatility of the limiting component. At the same time, the detachable locking method makes it convenient to disassemble when replacing the pipeline or performing maintenance without damaging the structure of the box 1.

[0025] Please see Figure 1-8 A positioning shaft 32 is rotatably mounted on the side of panel 31 near the movable plate 33. The positioning shaft 32 enables the movable plate 33 to form a foldable linkage structure. Panel 31 and movable plate 33 are connected to each other through the positioning shaft 32. The positioning shaft 32 connection ensures that the movable plate 33 is always associated with panel 31. When the movable plate 33 is opened, there is no need to find the alignment position. When it is closed, it can also be accurately aligned with the edge of panel 31, improving the smoothness of operation.

[0026] Please see Figure 1-8 A knob 22 is fixedly installed at the top of the adjusting rod 21, and the top of the adjusting rod 21 protrudes from the top of the panel 31. Through the cooperation of the adjusting rod 21 and the knob 22, users can accurately adjust the gas without opening the cover in daily life.

[0027] Please see Figure 1-8 The surface of the box body 1 is provided with multiple sets of protrusions 11. The protrusions 11 are integrally molded with the box body 1, which increases the overall rigidity of the surface of the box body 1. The top of the box body 1 corresponds to the bottom of the cover 3. The corresponding protrusions 11 and the bottom structure of the cover 3 can form a mechanical engagement. When installing the cover 3, there is no need to repeatedly adjust the position of the cover 3. Just align the groove at the bottom of the cover 3 with the protrusions 11 of the box body 1 to quickly complete the initial positioning, which greatly shortens the installation time. It is especially suitable for non-professionals to operate and reduces the difficulty of alignment.

[0028] Please see Figure 1-8A support strip 15 is fixedly connected to the bottom of the cover 3. The support strip 15 and the cover 3 are connected and fixed to each other by bolts or pins. The support strip 15 can provide stable bottom support for the cover 3, preventing the cover 3 from sinking and deforming due to its own weight or external pressure. The support strip 15 has a U-shaped design, which gives the support strip 15 natural elastic cushioning performance. When the cover 3 is inserted into the box 1, the U-shaped structure can deform slightly to adapt to the small dimensional errors of the inner wall of the box 1. After installation, it elastically resets and forms a tight fit, which can better adapt to the differences in installation accuracy of the box 1 after different wall grooves, improve assembly adaptability. In addition, the two sides of the support strip 15 are attached to the inner wall of the box 1, and the two sides are attached to form a bidirectional clamping force to limit the left and right displacement of the cover 3.

[0029] The working principle of this utility model is as follows: Before installing the gas outlet box, the box body 1 needs to be assembled. Align the insert plate 41 of the connecting block 4 with the slot 12 opened at the end of the box body 1, and use a bottom-up assembly method until the bottom end of the connecting block 4 is flush with the bottom end of the box body 1. At this time, the insert plate 41 and the protruding structure on the side of the connecting block 4 will form a bidirectional extrusion force. The insert plate 41 fits tightly against the inner wall of the slot 12, and the protrusion abuts against the end of the box body 1. The mechanical stress offsets the splicing gap, thereby ensuring the stability of the installation. After the connecting blocks 4 at both ends are installed, the two fixing plates 1 are... 3. Insert the pre-set groove at the bottom of the box 1. Observe whether both ends of the fixing plate 13 are fully inserted through the through hole at the bottom of the box 1 to ensure that the fixing plate 13 is not offset. The wall is pre-cut with a groove that matches the size of the box 1. Insert the assembled box 1 into the groove. Connect the box 1 to the wall base through the fixing holes on both sides of the box 1 with bolts. During the bolt tightening process, the horizontal and vertical of the box 1 should be calibrated at the same time to ensure that the box 1 is flush with the wall and not tilted. The installation of the box 1 needs to leave a height that protrudes from the wall and matches the thickness of the cover 3 in order to install the cover 3. When installing the gas pipeline, place valve 2 in the center of the box 1. The gas pipeline passes through the through hole in the middle of the connecting block 4 at both ends of the box 1 and connects with the gas inlet and outlet of valve 2 respectively. After the connection is completed, use the arc-shaped metal pressure plate 14 to cover the pipes at both ends of valve 2 and the fixing plate 13 exposed at the bottom of the box 1. Lock the metal pressure plate 14 and fixing plate 13 by passing through the through hole with pins or screws. The clamping force of the metal pressure plate 14 can fix the position of the pipeline, offset the risk of loosening caused by equipment operation vibration or external force contact, and ensure the airtightness of the pipeline interface. Then install the adjusting rod 21 to the matching position on one side of valve 2. When installing the cover 3, first connect the top of the U-shaped support strip 15 to the bottom of the cover 3 using pins or screws. After that, vertically insert the cover 3, with the support strips 15 installed at both ends of the bottom, into the inner wall of the box 1. At this time, the adjusting rod 21 passes through the through hole in the middle of the cover 3. The bottom of the cover 3 corresponds to the shape of the protrusions 11 set on the inner and outer walls of the box 1. Initial fixation can be completed without tools. At the same time, the elasticity of the support strips 15 on both sides can generate an outward pushing force on the inner wall of the box 1, tightly fitting the inner wall of the box 1, eliminating the assembly gap between the cover 3 and the box 1, and preventing the cover 3 from shaking. To enhance stability, the panel 31 and the movable plate 33 are then connected to each other via the positioning shaft 32. The positioning function of the positioning shaft 32 can limit the relative displacement between the panel 31 and the movable plate 33. After assembly, the panel 31 is installed on the top surface of the cover 3 by pressing. Finally, the knob 22 is installed on the top of the adjusting rod 21. Users can rotate the knob 22 to drive the adjusting rod 21 to control the opening and closing of the valve 2. When maintenance is required, the movable plate 33 can be opened to directly access the valve 2 and the pipe interface without disassembling the cover 3 or the panel 31.
