Description

Technical Field

[0001] This utility model belongs to the technical field of gas pressure regulating boxes, and in particular relates to a simple gas pressure regulating box monitoring device. Background Technology

[0002] A gas pressure regulating box is a device used to regulate gas pressure. It is usually placed in a dedicated box for easy installation and use. Its main function is to regulate the gas pressure and ensure that the gas supply system can provide a stable pressure according to the user's actual needs. Gas pressure regulating boxes can handle various types of gases, such as natural gas, city gas, liquefied petroleum gas, and mixed gases.

[0003] Gas monitoring devices are required during the use of gas pressure regulating boxes. These devices monitor the gas concentration in real time and promptly alert users when a gas leak occurs. To ensure their normal operation, regular maintenance is necessary. However, existing gas monitoring devices are usually fixed with bolts, making installation and disassembly quite troublesome and affecting maintenance efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a simple gas pressure regulating box monitoring device. By setting a trapezoidal block, specifically, when the gas detection device needs to be repaired, the protective shell is removed, and then the trapezoidal block is pressed so that the back of the trapezoidal block contacts the front of the latch. At this time, the two latches move in opposite directions simultaneously due to the pressure of the trapezoidal block. Then, the two limit rods slide on the left and right sides of the support frame, respectively. Then the latches disengage from the buckles, and the gas detection device can be lifted up to remove it. This allows for quick disassembly of the gas detection device and solves the problem that existing gas monitoring devices are usually fixed with bolts, which affects the maintenance efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a simple gas pressure regulating box monitoring device, comprising a pressure regulating box and a gas monitoring device. The gas monitoring device includes a gas sensor, which is fixedly connected to the inner wall of the pressure regulating box. A support frame two is fixedly connected to the side of the pressure regulating box near the gas monitoring device. Two latches are slidably connected inside the support frame two. The latches are J-shaped. Buckles are fixedly connected to the left and right sides of the gas monitoring device. The outer surface of the latches contacts the outer surface of the buckles. Limiting rods are fixedly connected to opposite sides of the two latches. The outer surfaces of the two limiting rods are slidably connected to the left and right sides of the support frame two, respectively. Springs two are sleeved on the outer surfaces of the limiting rods. A trapezoidal block is in contact with the front of the two latches. Two springs three are fixedly connected to the bottom of the trapezoidal block. By pressing the trapezoidal block, the gas detection device can be quickly disassembled, facilitating maintenance and improving maintenance efficiency.

[0007] Furthermore, the outer surface of the gas monitoring device is provided with a protective shell, and the bottom left and right sides of the protective shell are provided with sliding grooves. Two slide rails are fixedly connected to the side of the pressure regulating box near the protective shell. The outer surface of the slide rails is slidably connected to the inner wall of the sliding groove. The protective shell on the outer surface of the gas monitoring device effectively protects the gas monitoring device from the influence of the external environment, such as dust and water vapor, reduces the damage to the monitoring device caused by environmental factors, and improves its service life and monitoring accuracy.

[0008] Furthermore, the pressure regulating box is provided with a door on the front, and a sealing ring is fixedly connected to the side of the pressure regulating box near the door. A rain cover is provided on the top of the pressure regulating box. The door on the front of the pressure regulating box is equipped with a sealing ring. During daily use and maintenance, the door can effectively seal the internal space of the pressure regulating box to prevent external dust, moisture and other impurities from entering. At the same time, the sealing ring can further enhance the sealing effect.

[0009] Furthermore, the bottom of the rain cover is fixedly connected to two plug rods, and the top of the pressure regulating box has two insertion holes. The bottom of the plug rods passes through the insertion holes on the top of the pressure regulating box and extends into the interior. The plug rod design allows the rain cover to be securely installed on the pressure regulating box. When used outdoors, the rain cover can effectively block rainwater and prevent rainwater from entering the pressure regulating box and damaging the equipment, thus improving the protective effect of the pressure regulating box.

[0010] Furthermore, a support frame is fixedly connected to the inner wall of the pressure regulating box near the insertion rod. A slider is slidably connected inside the support frame. The slider is L-shaped. The support frame provides stable support and sliding trajectory for the slider, thereby improving the stability of the slider.

[0011] Furthermore, a fixing rod is fixedly connected to the side of the slider near the insertion rod. A groove is formed on the outer surface of the insertion rod. The outer surface of the fixing rod contacts the groove formed on the outer surface of the insertion rod. The groove design allows the fixing rod to be well fixed in contact with the insertion rod, thereby fixing the rain cover and improving the stability of the rain cover.

[0012] Furthermore, a spring is fixedly connected to the side of the slider away from the insertion rod, and the side of the spring away from the slider is fixedly connected to the inner wall of the pressure regulating box. A pull rod is fixedly connected to the bottom of the slider. The pull rod facilitates the user's installation or removal of the rain cover. The spring allows the fixed rod to make close contact with the insertion rod after the pull rod is released, further improving the stability of the rain cover.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model, by setting a trapezoidal block, allows for the following: When the gas detection device needs maintenance, the protective shell is removed, and then the trapezoidal block is pressed so that the back of the trapezoidal block contacts the front of the latch. At this time, the two latches move in opposite directions simultaneously due to the pressure of the trapezoidal block. Then, the two limiting rods slide on the left and right sides of the support frame, respectively, and the latches disengage. The gas detection device can then be lifted upwards to remove it. This allows for quick disassembly of the gas detection device, facilitating maintenance and improving maintenance efficiency.

[0015] 2. This utility model features a rain cover. Specifically, the rain cover is installed by first pulling the lever, which causes the slider to slide on the inner wall of the support frame. The insertion rod is then aligned with the insertion hole on the top of the pressure regulating box and inserted. After releasing the lever, the spring force causes the outer surface of the fixing rod to make tight contact with the groove on the outer surface of the insertion rod, thus fixing the rain cover. This prevents rainwater from entering the pressure regulating box and the gas detection device, causing internal parts to rust and be damaged, thereby improving the protective effect of the device.

[0016] 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

[0025] 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 scope of protection of the present utility model.

[0026] Please see Figures 1-5As shown, this utility model is a simple gas pressure regulating box monitoring device, including a pressure regulating box and a gas monitoring device. The gas monitoring device includes a gas sensor, which is fixedly connected to the inner wall of the pressure regulating box. A support frame two is fixedly connected to the side of the pressure regulating box near the gas monitoring device. Two latches are slidably connected inside the support frame two. The latches are J-shaped. Buckles are fixedly connected to the left and right sides of the gas monitoring device. The outer surfaces of the latches contact the outer surfaces of the buckles. Limit rods are fixedly connected to opposite sides of the two latches. The outer surfaces of the two limit rods are slidably connected to the left and right sides of the support frame two, respectively. Springs two are sleeved on the outer surfaces of the limit rods. A trapezoidal block is in contact with the front of the two latches. A bottom of the trapezoidal block is fixedly connected to... Two springs are provided. A protective shell is installed on the outer surface of the gas detection device. Slide grooves are provided on the left and right sides of the bottom of the protective shell. Two slide rails are fixedly connected to the side of the pressure regulating box near the protective shell. The outer surface of the slide rails slides in contact with the inner wall of the slide groove. A trapezoidal block 234 is provided. Specifically, when the gas detection device 2 needs maintenance, the protective shell 22 is removed, and then the trapezoidal block 234 is pressed, causing the back of the trapezoidal block 234 to contact the front of the latch 231. At this time, the two latches 231 move simultaneously in opposite directions due to the pressure of the trapezoidal block 234. The two limit rods 232 slide on the left and right sides of the support frame 23 respectively. Then, the latches 231 disengage from the buckle 236, and the gas detection device 2 is lifted upwards. This can be removed, allowing for quick disassembly of the gas detection device 2, facilitating maintenance and improving efficiency. The pressure regulating box has a door on the front, with a sealing ring fixedly connected to the side near the door. A rain cover is installed on the top of the pressure regulating box, with two rods fixedly connected to the bottom. Two insertion holes are opened on the top of the pressure regulating box, with the bottom of the rods passing through these holes and extending into the interior. A support frame is fixedly connected to the inner wall of the pressure regulating box near the rods, with a slider slidably connected inside the support frame. The slider is L-shaped, and a fixing rod is fixedly connected to the side of the slider near the rods. A groove is formed on the outer surface of the rods, and the outer surface of the fixing rod engages with the groove on the outer surface of the rods. A spring is fixedly connected to the side of the slider away from the insertion rod. The side of the spring away from the slider is fixedly connected to the inner wall of the pressure regulating box. A pull rod is fixedly connected to the bottom of the slider. By setting up a rain cover 12, specifically by installing the rain cover 12, first pull the pull rod 134 to make the slider 131 slide on the inner wall of the support frame 13. Align the insertion rod 121 with the insertion hole on the top of the pressure regulating box 1 and insert it. After releasing the pull rod 134, the elastic force of the spring 133 causes the outer surface of the fixing rod 132 to make close contact with the groove on the outer surface of the insertion rod 121, thus completing the fixation of the rain cover 12. This can prevent rainwater from entering the pressure regulating box 1 and the gas detection device 2, causing internal parts to rust and be damaged, and improving the protective effect of the device.

[0027] A specific application of this embodiment is as follows: During use, the MR007 gas sensor 21 can monitor the gas concentration inside the pressure regulating box 1 in real time. When the gas sensor 21 detects a gas leak, the GRTU-200 gas monitoring device 2 reports the real-time situation to the user via the internet and simultaneously issues a voice prompt. The user can then promptly close the gas valve 15 for maintenance to prevent gas leaks from causing accidents. When maintenance of the gas detection device 2 is required, lift the protective shell 22 upwards, allowing the slide groove 221 to slide on the outer surface of the slide rail 222 to remove the protective shell 22. Then press the trapezoidal block 234, causing the back of the trapezoidal block 234 to contact the front of the latch 231. At this time, the two latches 231 move simultaneously in opposite directions due to the pressure of the trapezoidal block 234. The two limit rods 232 then slide on the left and right sides of the support frame 23, respectively. The latches 231 then disengage from the buckle 236, and the gas detection device 2 can be removed by lifting it upwards. The same principle applies during installation. Press the trapezoidal block 231... 34. Install the gas detection device 2 inside the support frame 23. Then, due to the elastic force of springs 233 and 235, the latch 231 and trapezoidal block 234 are reset respectively, so that the latch 231 and the buckle 236 are in tight contact, thus completing the fixation of the gas detection device 2. This allows for quick installation and disassembly of the gas detection device 2 and facilitates its maintenance. When using the pressure regulating box 1 outdoors, a rain cover 12 needs to be installed. First, pull the lever 134 to make the slider 131... The inner wall of the support frame 13 slides, and the insertion rod 121 is aligned with the insertion hole on the top of the pressure regulating box 1 and inserted. After the pull rod 134 is released, the outer surface of the fixing rod 132 is in close contact with the groove on the outer surface of the insertion rod 121 due to the elastic force of the spring 133, thus completing the fixation of the rain cover 12. This can prevent rainwater from entering the pressure regulating box 1 and the gas detection device 2, causing internal parts to rust and be damaged. The sealing ring 111 set between the box door 11 and the sealing ring 111 further improves the protective effect of the pressure regulating box 1.
