When the detection end of the alarm device is blocked by fuel impurities, a large number of threaded components need to be disassembled and reassembled, which is time-consuming and labor-intensive and affects the maintenance efficiency of the alarm device.

[0005] Therefore, the burner air-fuel mixing abnormality alarm needs to be redesigned and modified. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide a burner air-fuel mixing abnormality alarm device that is easy to disassemble and assemble. It has the advantage of being easy to disassemble and assemble, and solves the problem that existing alarm devices mainly rely on flanges to connect to pipelines. When the detection end of the alarm device is blocked by fuel impurities, a large number of threaded components need to be disassembled and reassembled, which is time-consuming and laborious and affects the maintenance efficiency of the alarm device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a burner air-fuel mixing abnormality alarm device that is easy to disassemble and assemble, including a body; The back of the machine body is connected to a detection tube. Both ends of the detection tube are provided with connecting discs. The end of the connecting disc near the detection tube extends into the detection tube and is inserted into the detection tube. A transmission plate is provided on the back of the detection tube. Both ends of the left and right sides of the transmission plate are movably connected to cranks via pins. The end of the crank away from the transmission plate is movably connected to a connecting block via a pin. An extrusion frame is fixedly connected to the surface of the connecting block. The extrusion frame is located inside the connecting disc and contacts the surface of the connecting disc.

[0008] In a preferred embodiment of this invention, a screw is movably connected to the back of the detection tube via a bearing. The rear end of the screw passes through the transmission plate and extends to the back of the transmission plate. A rotating wheel is fixedly connected to the rear end of the screw. The transmission plate and the screw are threaded together.

[0009] As a preferred embodiment of this utility model, a support plate located in front of the rotating wheel is sleeved on the surface of the screw, and the top and bottom ends of the support plate extend to both sides of the transmission plate and are fixedly connected to the back of the detection tube.

[0010] In a preferred embodiment of this invention, a limiting plate is fixedly connected to the back of the detection tube, and guide rods are fixedly connected to both the left and right sides of the limiting plate. The extrusion frame is sleeved on the surface of the guide rods and slidably connected to the guide rods.

[0011] As a preferred embodiment of this invention, the top and bottom of the detection tube are fixedly connected with sealing rings, the inner surface of the sealing rings is in contact with the surface of the connecting disc, and the sealing rings are elastic.

[0012] As a preferred embodiment of this utility model, a plug sleeve is fixedly connected to the back of the connecting plate, and the plug sleeve is semi-circular in shape with a notch in the center.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model sets connecting plates at both ends of the detection tube and inserts them into the detection tube, and sets a linkage mechanism on the back consisting of a transmission plate, crank, connecting block and extrusion frame. This enables the extrusion frames on both sides to move synchronously by operating only a single transmission component, thereby quickly tightening or loosening the connecting plates. This achieves the effect of eliminating a large number of bolts of traditional flanges, simplifying disassembly and assembly operations, and improving maintenance efficiency.

[0014] 2. This utility model achieves precise control of the forward and backward movement of the transmission plate by setting a bearing-connected screw on the back of the detection tube and threading the screw to the transmission plate. At the same time, a rotating wheel is fixed at the rear end of the screw. This converts the rotational motion into linear motion, providing a stable and labor-saving transmission method, and making it easy for operators to apply and control the clamping force.

[0015] 3. This utility model achieves effective support for the screw by sleeved on the surface of the screw and fixedly connected to the back of the detection tube, and provides moving space for the transmission plate. This increases the stability of the screw during rotation, prevents it from deflecting or swaying, and achieves the effect of ensuring smooth transmission, improving the overall reliability and service life of the mechanism.

[0016] 4. This utility model achieves precise constraint on the movement direction of the extrusion frame by fixing a limiting plate on the back of the detection tube and fixing guide rods on both sides of the limiting plate, so that the extrusion frame slides on the guide rods. This ensures that the extrusion frame can only move in a straight line along the guide rods, preventing the extrusion frame from deflecting or getting stuck during the pressing or releasing process. This ensures smooth clamping action and accurate alignment, thereby guaranteeing the reliability of the seal.

[0017] 5. This utility model achieves an effective seal at the connection point by setting elastic sealing rings at the top and bottom of the detection tube and making the inner surface of the sealing rings contact the surface of the connecting plate. This is achieved by filling the gap with the elastic deformation of the sealing rings while the extrusion frame presses the connecting plate, thus preventing media leakage and ensuring the airtightness of the detection environment.

[0018] 6. This utility model achieves guidance and initial positioning of the connecting plate during initial docking by fixing a semi-circular plug sleeve with a notch in the center on the back of the connecting plate. At the same time, the notch design facilitates the accommodation of pipe fittings, making the installation alignment faster and more accurate, and further simplifying the initial installation steps.

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.

[0022] like Figures 1 to 4 As shown, the present invention provides a burner air-fuel mixing abnormality alarm device that is easy to disassemble and assemble, including a body 1; The back of the body 1 is connected to a detection tube 2. Both ends of the detection tube 2 are provided with connecting discs 3. The end of the connecting disc 3 near the detection tube 2 extends into the interior of the detection tube 2 and is inserted into the detection tube 2. A transmission plate 4 is provided on the back of the detection tube 2. Both ends of the left and right sides of the transmission plate 4 are movably connected to cranks 5 by pins. The end of the crank 5 away from the transmission plate 4 is movably connected to a connecting block 6 by pins. A pressing frame 7 is fixedly connected to the surface of the connecting block 6. The pressing frame 7 is located inside the connecting disc 3 and is in contact with the surface of the connecting disc 3.

[0023] refer to Figure 2 The back of the detection tube 2 is movably connected to a screw 8 via a bearing. The rear end of the screw 8 passes through the transmission plate 4 and extends to the back of the transmission plate 4. The rear end of the screw 8 is fixedly connected to a rotating wheel 9. The transmission plate 4 and the screw 8 are threaded together.

[0024] As a technical optimization of this utility model, by setting a bearing-connected screw 8 on the back of the detection tube 2 and threading the screw 8 to the transmission plate 4, and fixing a rotating wheel 9 at the rear end of the screw 8, the forward and backward movement of the transmission plate 4 can be precisely controlled by rotating the rotating wheel 9, converting the rotational motion into linear motion, thus achieving a stable and labor-saving transmission method, and making it convenient for operators to apply and control the clamping force.

[0025] refer to Figure 3 The screw 8 is fitted with a support plate 10 located in front of the rotating wheel 9. The top and bottom ends of the support plate 10 extend to both sides of the transmission plate 4 and are fixedly connected to the back of the detection tube 2.

[0026] As a technical optimization of this utility model, by sleeved on the surface of the screw 8 and fixedly connected to the back of the detection tube 2, and providing moving space for the transmission plate 4, the screw 8 is effectively supported, the stability of the screw 8 during rotation is increased, and its deflection or sway is prevented, thereby achieving the effect of ensuring smooth transmission, improving the overall reliability and service life of the mechanism.

[0027] refer to Figure 3The back of the detection tube 2 is fixedly connected to a limiting plate 11. Guide rods 12 are fixedly connected to the left and right sides of the limiting plate 11. The extrusion frame 7 is sleeved on the surface of the guide rods 12 and is slidably connected to the guide rods 12.

[0028] As a technical optimization of this utility model, by fixing a limiting plate 11 on the back of the detection tube 2 and fixing guide rods 12 on both sides of the limiting plate 11, the extrusion frame 7 slides on the guide rods 12, thereby achieving precise constraint on the movement direction of the extrusion frame 7, so that it can only move in a straight line along the guide rods 12, preventing the extrusion frame 7 from deflecting or getting stuck during the pressing or releasing process, thus ensuring smooth clamping action and accurate alignment, thereby ensuring the reliability of the seal.

[0029] refer to Figure 3 The top and bottom of the detection tube 2 are fixedly connected with sealing rings 13. The inner surface of the sealing ring 13 is in contact with the surface of the connecting plate 3. The sealing ring 13 is elastic.

[0030] As a technical optimization of this utility model, by setting elastic sealing rings 13 at the top and bottom of the detection tube 2 and making the inner surface of the sealing rings 13 contact the surface of the connecting plate 3, the elastic deformation of the sealing rings 13 fills the gap while the extrusion frame 7 presses the connecting plate 3, thus achieving an effective seal at the connection point, preventing media leakage, and ensuring the airtightness of the detection environment.

[0031] refer to Figure 1 A plug sleeve 14 is fixedly connected to the back of the connecting plate 3. The plug sleeve 14 is semi-circular in shape and has a notch in the center.

[0032] As a technical optimization of this utility model, by fixing a semi-circular plug sleeve 14 with a notch in the center on the back of the connecting plate 3, the connecting plate 3 is guided and initially positioned during the initial docking. At the same time, the notch design facilitates the accommodation of pipe fittings, thereby making the installation alignment faster and more accurate, and further simplifying the initial installation steps.

[0033] The working principle and usage process of this utility model are as follows: During installation, the connecting discs 3 at both ends of the detection tube 2 are first inserted into the external pipe interface for initial alignment. The semi-circular insertion sleeve 14 on the back of the connecting disc 3 helps with guidance. Then, the operator rotates the rotating wheel 9 clockwise, which drives the screw 8 to rotate. Since the screw 8 is connected to the transmission plate 4 by a thread, the rotational motion is converted into the linear movement of the transmission plate 4. The movement of the transmission plate 4 drives the cranks 5 on both sides to swing through the pin shaft. The connecting block 6 at the other end of the crank 5 pulls the extrusion frame 7 to slide inward along the guide rod 12, thereby pressing the surface of the connecting disc 3 tightly like a caliper to form a reliable airtight connection and complete the rapid installation. After the device is put into operation, the air-fuel mixture flowing through the detection tube 2 is monitored in real time by the sensor in the body 1. Once the mixing ratio or flow state is abnormal, the device will immediately trigger an alarm. When maintenance and cleaning are required, simply rotate the wheel 9 counterclockwise, move the transmission plate 4 backward, and use the crank 5 mechanism to expand the squeezing frame 7 outward, loosen the fastening of the connecting plate 3, and the entire detection tube 2 unit can be easily pulled out of the pipe, saving time and effort in the maintenance process.

[0034] In summary, this easy-to-disassemble burner air-fuel mixing abnormality alarm device, by setting connecting plates 3 at both ends of the detection tube 2 and inserting them into the detection tube 2, and setting a linkage mechanism on the back consisting of a transmission plate 4, a crank 5, a connecting block 6 and a pressing frame 7, achieves the effect of driving the pressing frames 7 on both sides to move synchronously by operating only a single transmission component, thereby quickly tightening or loosening the connecting plates 3. This achieves the effect of eliminating a large number of bolts of traditional flanges, simplifying disassembly and assembly operations, and improving maintenance efficiency.
