Description

Technical Field

[0001] This utility model relates to the field of safety equipment, and in particular to a natural gas leak warning device. Background Technology

[0002] As a crucial safety device, the natural gas leak detector's core function is to monitor the concentration of natural gas in the air in real time and with high accuracy using a built-in gas sensor. Once the gas concentration is detected to exceed safe limits, the sampling circuit quickly converts this information into an electrical signal and transmits it to the control circuit. Upon recognizing this emergency signal, the control circuit immediately activates the alarm system, promptly alerting the homeowner to check their natural gas appliances, thereby effectively preventing safety accidents caused by natural gas leaks.

[0003] In existing technologies, some natural gas leak detectors are installed by directly fixing them to the wall, which makes it inconvenient to repair and replace them when they malfunction. At the same time, it is inconvenient to replace the wiring of existing natural gas leak detectors. Therefore, it is necessary to propose a natural gas leak detector to solve the above problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a natural gas leak warning device. Because the natural gas leak warning device is equipped with a loading box and a fixing box, after the natural gas leak warning device detector is installed inside the loading box, it achieves the effect of facilitating the removal, repair and replacement of the natural gas leak warning device detector when it malfunctions, thereby improving the problem of the inconvenience of disassembly and installation of existing natural gas leak warning device detectors.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A natural gas leak warning device includes:

[0007] The loading box contains a natural gas detection gauge, and there are fixing boxes on both sides of the outer wall;

[0008] A fixed box contains a fixed plate, on which a first rotating rod is movably connected. One end of the first rotating rod is connected to a control rod, and the other end of the control rod is connected to a second rotating rod. A control handle and a transmission rod are connected to the second rotating rod.

[0009] The transmission rod is connected to the clamping block via a hinged post; the inner bottom surface of the fixing box is also fixed with a fixing post for engaging the transmission rod.

[0010] In some embodiments, the clamping block is placed on a sliding plate, which is disposed on the bottom surface of the fixing box.

[0011] In some embodiments, a wiring assembly is also included, the wiring assembly comprising:

[0012] The connector is fixedly installed inside the natural gas detection meter;

[0013] An insulating partition, which is fixedly connected inside the connector, is used to achieve insulation isolation between the positive and negative wires inside the connector;

[0014] Multiple insulating positioning rods are fixedly connected to the inner wall of the connector, which is separated by insulating partitions;

[0015] A spring, one end of which is fitted onto an insulating positioning rod, and the other end is constrained by a rubber gasket;

[0016] A conductive metal is fixedly connected to the bottom of a rubber gasket to make contact with the copper core for electrical connection.

[0017] In some embodiments, an insulating fixing sleeve is provided inside the conductive metal to prevent the portion of the copper core that is not in contact with the conductive metal from being exposed.

[0018] In some embodiments, two hinged end plates are fixedly installed on the outer wall of the loading box; each of the two hinged end plates is fixedly connected to a mating plate; the two mating plates can be locked by a pin, thereby forming a enclosure for the natural gas sensor.

[0019] In some embodiments, the natural gas meter is equipped with indicator lights and alarm lights.

[0020] In some embodiments, the connector has a detachably connected wire inside, and the copper core may be the inner core of the wire.

[0021] In some embodiments, the control handle is fixedly connected to a cover plate, which is used to prevent dust from entering the housing.

[0022] In some embodiments, the connector is made of an insulating material, and the spring is an insulating spring.

[0023] This utility model has the following beneficial effects:

[0024] 1. The natural gas leak warning device of this utility model, due to the design of the fixing box, places the natural gas detector inside the loading box. By pulling the control handle, the clamping block is moved, and the clamping block clamps the natural gas detector to secure it, thus firmly fixing the natural gas detector inside the loading box. When disassembly is required, the control handle is pulled in the opposite direction, thereby realizing the quick disassembly and installation of the natural gas detector, which greatly improves work efficiency.

[0025] 2. This utility model's natural gas leak warning device, due to its wiring assembly design, allows for easy replacement of aging wires inside the natural gas detector. The aging wire can be pulled out, and the copper core of the new external wire can be inserted into the insulating retaining sleeve. A spring will press down on the conductive metal, ensuring better contact between the conductive metal and the copper core. By adding a wiring device, damaged external wires can be quickly replaced, greatly improving work efficiency. Attached Figure Description

[0033] 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.

[0034] See Figures 1-6 This utility model provides a natural gas leak warning device, comprising: a loading box 1, a fixing box 2, and a transmission rod 10. The loading box 1 contains a natural gas detector 15 for detecting natural gas leaks. Fixing boxes 2 are located on both sides of the outer wall of the loading box 1. A fixing plate 8 is fixed inside each fixing box 2, and a first rotating rod 4 is movably connected to the fixing plate 8. One end of the first rotating rod 4 is connected to a control rod 7, and the other end of the control rod 7 is connected to a second rotating rod 41. A control handle 3 and the transmission rod 10 are simultaneously connected to the second rotating rod 41. The transmission rod 10 is connected to a clamping block 11 via a hinged post 5. A fixing post 9 is also fixed to the inner bottom surface of the fixing box 2 for engaging the transmission rod 10. Specifically, the top of the fixing post 9 has a slot, magnet, or other engaging part, used to engage the transmission rod 10 in this state when the clamping block 11 clamps the natural gas detector 15, making the clamping block 11 clamp the natural gas detector 15 more securely.

[0035] In some embodiments, the clamping block 11 may be placed or otherwise positioned above the sliding plate 12, which is disposed on the bottom surface of the fixing box 2. The contact surface between the sliding plate 12 and the clamping block 11 is a smooth surface, specifically, it may be covered with a smooth coating or treated with a smooth surface. This arrangement can reduce the friction of the clamping block 11, making it easier to clamp the natural gas detector 15 by operating the clamping block 11 with the control handle 3.

[0036] In some embodiments, a wiring assembly is further included, comprising: a connector 18 and an insulating partition 24. The connector 18 is fixedly disposed inside the natural gas detector 15. The insulating partition is fixedly connected inside the connector 18 to achieve insulation isolation between the positive and negative wires inside the connector 18. A plurality of insulating positioning rods 22 are fixedly connected to the inner wall of the connector 18 separated by the insulating partition 24. One end of a spring 28 is sleeved on the insulating positioning rod 22, and the other end is constrained by a rubber gasket 25. A conductive metal 23 is fixedly connected to the rubber gasket 25 for contacting the copper core 26 to achieve electrical connection.

[0037] It should be noted that the other end of the spring 28 is constrained by the rubber gasket 25 as follows: the rubber gasket 25 can be a rubber ring, and the spring 28 is housed in the inner ring of the rubber ring, or the rubber ring and the spring 28 are integrally connected.

[0038] In some embodiments, the insulating positioning rod 22 is an insulating positioning rod made of an elastic material.

[0039] In some embodiments, an insulating retaining sleeve 27 is provided between the conductive metals 23 to prevent the portion of the copper core 26 not in contact with the conductive metals 23 from being exposed. Specifically, the copper core 26 may be the inner core of an electrical wire 19 used to supply power to the natural gas detector 15.

[0040] In some embodiments, two hinges 13 are fixedly provided on one end plate of the outer wall of the loading box 1; the other end plate of the two hinges 13 is fixedly connected to a hinge plate 21; the two hinge plates 21 can be locked by a pin 14, thereby forming a enclosure for the natural gas sensor 20.

[0041] In some embodiments, the natural gas meter 15 is equipped with indicator lights 16 and alarm lights 17 to enhance its functionality. Specifically, the natural gas meter 15 is connected to three indicator lights 16, which are designed to display three different states: normal, fault, and danger, in order to intuitively convey the current status of the natural gas system to the user.

[0042] In addition, the natural gas detector 15 is also equipped with an alarm light 17. When the natural gas concentration is detected to exceed the safety standard, a drive circuit built into the alarm light 17 (which can be regarded as a control unit closely related to the sensor) will be activated immediately, causing the alarm light 17 to emit an alarm signal in a preset manner (such as a specific flashing frequency, brightness change, etc.), thereby promptly reminding the homeowner to take necessary safety measures.

[0043] In some embodiments, see Figure 1 and Figure 5 The control handle 3 is fixedly connected to a cover plate 6, which is located inside the fixed box 2 to prevent dust from entering the fixed box 2 through the opening. This opening allows the control handle 3 to be moved.

[0044] In some embodiments, the connector 18 is made of an insulating material, and the spring 28 is a spring with insulating function.

[0045] In use, this utility model discloses a natural gas leak warning device. By pulling the control handle 3 diagonally backward, the control handle 3 drives the control rod 7 to rotate around the first rotating rod 4. This causes the control rod 7 to drive the second rotating rod 41, which in turn drives the transmission rod 10 to move diagonally backward. This causes the clamping blocks 11 to move backward, displacing the clamping blocks 11 on both sides of the loading box 1 to release the natural gas detector 15. Conversely, by operating the control handle 15 diagonally backward, the clamping blocks 11 on both sides of the loading box 1 can move towards the center of the loading box 1 to clamp the natural gas detector 15, thereby fixing the natural gas detector 15. When it is necessary to put the natural gas detector 15 with the natural gas sensor 20 into the loading box 1, the two hinge plates 21 are opened by the hinge 13. After the detector is put in, the hinge plates 21 are closed and the pin 14 is inserted to lock it in place.

[0046] When it is necessary to replace the aging wire of the natural gas detector 15, the aging wire can be pulled out, the copper core 26 of the new external wire 19 to be replaced can be stripped out, and the copper core 26 of the external wire 19 can be inserted into the interior of the insulating fixing sleeve 27. The spring 28 will press down the conductive metal 23 to make the conductive metal 23 and the copper core 26 more fully in contact. The connector 18 is equipped with an insulating partition 24 to isolate the neutral wire and the live wire.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
