Description

Technical Field

[0001] This utility model relates to the field of gas pressure regulating box technology, specifically a gas pressure regulating box that is easy to maintain. Background Technology

[0002] Gas pressure regulating boxes are an important component of gas transmission and distribution systems. They are widely used due to their advantages such as compact structure, small footprint, cost savings, and convenient installation and use. The basic configuration inside the box includes inlet and outlet valves, filters, pressure regulators, and corresponding measuring instruments. Auxiliary safety devices such as bellows compensators, overpressure relief valves, and overpressure shut-off valves can also be added. At the same time, depending on the usage and user requirements, they can be assembled into single-channel, dual-channel, or multi-channel gas pressure regulating boxes.

[0003] Application number CN202420520961.4 discloses a gas pressure regulating box that is easy to maintain. The box includes a pressure regulating box body, which is formed by a base plate, a back plate integrally formed with one end of the base plate, side plates hinged to both ends of the back plate, and a lid hinged to the top of the back plate. A pressure regulating device is installed on the top of the base plate. A pop-up assembly for opening the lid is provided between the back plate and the lid. The pop-up assembly includes two sets of gas springs and a torsion spring. A sleeve is provided at one end of the lid. A fixing rod penetrating the inside of the sleeve is provided at the top of the back plate. The fixing rod is connected to the sleeve via a torsion spring. One side of the back plate is connected to the bottom of the lid via two sets of gas springs. This invention uses two sets of gas springs and a torsion spring to pop up the lid. Combined with the two hinged side plates, it facilitates the enclosure and unfolding of the pressure regulating box body. Furthermore, this design allows for easy exposure of the pressure regulating device, enabling staff to observe it from all angles and greatly improving operational convenience.

[0004] However, after the gas pressure regulating box is overhauled, the gas pipeline needs to be re-laid out and reinstalled. At this time, the required space will change, and the box itself does not have a corresponding adjustment structure, so it cannot adapt well to the changes and has a problem of weak adaptability. Utility Model Content

[0005] The purpose of this invention is to provide a gas pressure regulating box that is easy to maintain, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a gas pressure regulating box that is easy to maintain, including a U-shaped plate and a telescopic rod connected between the two U-shaped plates for adjusting the distance between the two U-shaped plates, which is suitable for different space scenarios;

[0008] The outer walls of the two U-shaped plates are provided with mounting plates, and the U-shaped plates are mounted on the wall surface through the mounting plates;

[0009] Both of the U-shaped plates have through holes at their bottoms for the insertion of gas pipes;

[0010] L-shaped plates are respectively installed on the outer walls of the two U-shaped plates, and the two L-shaped plates respectively close the outer ports of the U-shaped plates;

[0011] The L-shaped plate is adjusted according to the gap of the U-shaped plate. Insert plates are respectively provided on the outer walls of the U-shaped plate and the L-shaped plate, and the insert plates are used to close the port gap after adjustment.

[0012] Furthermore, the telescopic rod includes a mounting rod, which is fixedly connected to the inner wall of one of the U-shaped plates. A movable rod is slidably connected to the mounting rod, and the output end of the movable rod is connected to another U-shaped plate. A spring is installed inside the mounting rod, and the end of the movable rod inside the mounting rod compresses the spring.

[0013] Furthermore, slots are provided on the outer walls of the two U-shaped plates.

[0014] Furthermore, a plug is fixedly connected to the outer wall of the mounting plate, and the mounting plate is inserted into the slot through the plug. Mounting holes are respectively opened at both ends of the mounting plate.

[0015] Furthermore, guide rails are provided on the outer walls of the two U-shaped plates, and the L-shaped plate is slidably connected to the guide rails.

[0016] Furthermore, limit holes are respectively opened on the top of the two L-shaped plates, and a limit block is connected between the two limit holes.

[0017] This utility model has the following beneficial effects:

[0018] (1) Compared with the prior art, this utility model, through the setting of telescopic rod and limiting block, requires that after the gas is repaired, if other components need to be installed, the original working space needs to be changed to adapt to the installation and use after the repair. When the working space inside the device needs to be changed, when the gap of the U-shaped plate changes due to the adjustment of the telescopic rod, the space changes. Insert plates are respectively set on the outer walls of the U-shaped plate and the L-shaped plate. The insert plates are used to close the gap of the adjusted port, thereby forming a new working space, thereby improving the applicability and scope of application. After adjustment, the limiting block is used to limit and fix it to maintain its stability.

[0019] (2) This utility model uses telescopic rods and limiting blocks to open the port by sliding adjustment of the U-shaped plate and L-shaped plate. At the same time, the insert plate is detachable, which improves the efficiency of installation and disassembly, thus making it convenient to open the box and inspect the gas.

[0020] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1 - Figure 7As shown, this utility model is a gas pressure regulating box that is easy to maintain, including a U-shaped plate 1, and a telescopic rod 5 connected between the two U-shaped plates 1 for adjusting the distance between the two U-shaped plates 1, which is suitable for different space scenarios;

[0033] The outer walls of the two U-shaped plates 1 are provided with mounting plates 3, and the U-shaped plates 1 are mounted on the wall through the mounting plates 3;

[0034] Both U-shaped plates 1 have through holes 102 at their bottom for gas pipes to pass through.

[0035] Two L-shaped plates 2 are respectively installed on the outer walls of the two U-shaped plates 1, and the two L-shaped plates 2 respectively close the outer ports of the U-shaped plates 1;

[0036] The L-shaped plate 2 is adjusted along with the gap adjustment of the U-shaped plate 1. Insert plates 4 are respectively provided on the outer walls of the U-shaped plate 1 and the L-shaped plate 2. The insert plates 4 are used to close the port gap after adjustment.

[0037] The purpose of the above setup is to provide a stable mounting base for the entire device by mounting the two U-shaped plates 1 on the wall via the mounting plate 3 on the outer wall. Since the two U-shaped plates 1 are connected by a telescopic rod 5, the distance between them can be adjusted by the telescopic function of the rod 5. This design allows the device to be adapted to different spatial scenarios and meet the usage requirements of various spatial layouts. The through hole 102 provides a dedicated channel for the gas pipeline, allowing it to pass smoothly through the device to reach the required location. The outer ports of the two U-shaped plates 1 are respectively sealed by L-shaped plates 2. When the gap between the U-shaped plates 1 changes due to the adjustment of the telescopic rod 5, the L-shaped plates 2 can be adjusted accordingly. The insert plate 4 installed on the L-shaped plate 2 always maintains its sealing effect on the outer ports of the U-shaped plates 1. When the positions of the U-shaped plates 1 and L-shaped plates 2 change due to various adjustments to adapt to different spatial scenarios, the insert plate 4 is used to seal the adjusted port gap, thereby ensuring the sealing performance of the entire device under different conditions.

[0038] The telescopic rod 5 includes a mounting rod 501, which is fixedly connected to the inner wall of one of the U-shaped plates 1. A movable rod 502 is slidably connected to the mounting rod 501. The output end of the movable rod 502 is connected to the other U-shaped plate 1. A spring 503 is installed inside the mounting rod 501. The end of the movable rod 502 inside the mounting rod 501 compresses the spring 503.

[0039] The purpose of the above configuration is that when the distance between the two U-shaped plates 1 needs to be adjusted, the movable rod 502 slides relative to the mounting rod 501, and the spring 503 plays a role in buffering and assisting in resetting. When an external force causes the movable rod 502 to extend or retract, the spring 503 will apply a corresponding force to the movable rod 502 according to its elastic characteristics, making the telescopic rod 5 more stable during the distance adjustment process, and to a certain extent, it can make the movable rod 502 tend to return to its initial position after the external force disappears.

[0040] Slots 103 are provided on the outer walls of the two U-shaped plates 1;

[0041] The purpose of the above arrangement is that the insert block 302 on the outer wall of the mounting plate 3 is inserted into the slot 103 on the outer wall of the U-shaped plate 1, and this insertion method realizes the initial connection between the mounting plate 3 and the U-shaped plate 1.

[0042] A plug 302 is fixedly connected to the outer wall of the mounting plate 3. The mounting plate 3 is inserted into the slot 103 through the plug 302. Mounting holes 301 are respectively opened at both ends of the mounting plate 3.

[0043] The purpose of the above-mentioned setup is that the mounting holes 301 at both ends of the mounting plate 3 can be used to further fix the mounting plate 3 and the entire device to the wall using bolts or other connecting parts, so that the entire device is securely installed.

[0044] Guide rails 101 are provided on the outer walls of the two U-shaped plates 1, and L-shaped plates 2 are slidably connected to the guide rails 101;

[0045] The purpose of the above arrangement is that the guide rail 101 provides guidance for the movement of the L-shaped plate 2, ensuring that the L-shaped plate 2 can slide accurately on the guide rail 101 as the gap of the U-shaped plate 1 is adjusted, thereby opening and closing the outer port of the U-shaped plate 1, which facilitates gas maintenance.

[0046] Limiting holes 201 are respectively opened on the top of the two L-shaped plates 2, and a limiting block 6 is connected between the two limiting holes 201;

[0047] The purpose of the above setting is that when the gap of the U-shaped plate 1 changes due to the adjustment of the telescopic rod 5, a matching limiting block 6 is selected based on the changed length, and the two L-shaped plates 2 are fixed by the cooperation of the limiting block 6 and the limiting hole 201.

[0048] Working principle: When the distance between the two U-shaped plates 1 needs to be adjusted, the movable rod 502 slides relative to the mounting rod 501, and the spring 503 plays a role in buffering and assisting in resetting. When an external force causes the movable rod 502 to extend or retract, the spring 503 will apply a corresponding force to the movable rod 502 according to its elastic characteristics, making the telescopic rod 5 more stable during the distance adjustment process, and to a certain extent, it can make the movable rod 502 tend to return to its initial position after the external force disappears.

[0049] The guide rail 101 provides guidance for the movement of the L-shaped plate 2, ensuring that the L-shaped plate 2 can slide accurately on the guide rail 101 as the gap of the U-shaped plate 1 is adjusted, thereby opening and closing the outer port of the U-shaped plate 1, which facilitates gas maintenance.

[0050] When the gap of the U-shaped plate 1 changes due to the adjustment of the telescopic rod 5, a matching limiting block 6 is selected based on the changed length, and the two L-shaped plates 2 are fixed by the cooperation of the limiting block 6 with the limiting hole 201.

[0051] The insert 302 on the outer wall of the mounting plate 3 is inserted into the slot 103 on the outer wall of the U-shaped plate 1. This insertion method realizes the initial connection between the mounting plate 3 and the U-shaped plate 1. The mounting holes 301 at both ends of the mounting plate 3 can be used to further fix the mounting plate 3 and the entire device to the wall by bolts and other connecting parts, so that the entire device is firmly installed.

[0052] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
