Description
Technical Field
[0001] This utility model relates to the field of fire detector technology, and in particular to a combined gas fire detector. Background Technology
[0002] The modular gas fire detector is a flexible and efficient fire early warning device. Its portable design allows it to adapt to various complex environments. It is equipped with multiple different types of suction nozzles, which can be flexibly replaced according to the detection scenario to sample different gases or environments. For example, when detecting combustible gas leaks in industrial workshops, a dedicated high-sensitivity suction nozzle can be used, while when detecting smoke in densely populated areas, a suction nozzle suitable for capturing tiny smoke particles can be used. These suction nozzles transmit the collected gas samples to the control console, where the built-in intelligent analysis system analyzes data such as gas composition and concentration in real time. Once an anomaly is detected, an alarm is immediately issued.
[0003] In existing technologies, the display screens of combined gas fire detectors present some inconveniences in terms of use. On the one hand, the screen cannot be stored inside the device, making it susceptible to damage from external impacts during transport or storage, increasing maintenance costs and uncertainty regarding the device's lifespan. On the other hand, the screen angle is not adjustable, limiting the user's operating experience from different perspectives. For example, when installed at a height or used in a confined space, users need to frequently adjust their posture to see the screen content clearly, reducing work efficiency. This fixed screen design cannot meet the usage needs of diverse scenarios. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a combined gas fire detector.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a combined gas fire detector, including a detection console, a display screen on the top of the detection console, multiple gas collecting nozzles on one side of the detection console, a component slot on the top of the detection console, a support plate one and a support plate two fixed to the inner wall of the component slot, a lead screw rotatably connected to one side of the support plate one and the support plate two, a sliding rod fixed to one side of the support plate one and the support plate two, a driving component threadedly connected to the surface of the lead screw, driving rods rotatably connected to both sides of the driving component, a driving block rotatably connected to one side of the two driving rods, two support blocks fixed to the inner wall of the component slot, the display screen rotatably connected to one side of the support block, the driving block fixed to the bottom of the gas collecting nozzle, and the lead screw driven to rotate by a driving device.
[0006] Preferably, the detection console has multiple air intake columns on one side, and each of the multiple air collecting nozzles has an air intake hole inside. The air intake columns are located on the inner wall of the air intake holes. Each of the multiple air collecting nozzles has a locking seat fixed on one side. The detection console has multiple locking slots on one side. The inner wall of each locking slot has a sliding groove. The inner wall of each locking slot has a first locking shaft and a second locking shaft. Both ends of the first locking shaft and the second locking shaft are fixed with sliders. The sliders slide on the inner wall of the sliding groove. Both ends of each slider are fixed with springs, and the other end of each spring is fixed to the inner wall of the sliding groove. In existing technologies, the gas collection nozzle of combined gas fire detectors suffers from inconvenient replacement. Because the connection between the gas collection nozzle and the detection control console is relatively fixed, replacement typically requires complex disassembly steps and specialized tools. This design is extremely inconvenient in practical use, especially in emergencies or when rapid nozzle replacement is needed to adapt to different detection environments. Frequent disassembly can also lead to loosening or damage of the connection points, affecting the detector's sealing and accuracy. Furthermore, the complexity of the replacement process increases maintenance costs and time, reduces the equipment's flexibility and practicality, and makes it difficult to meet the needs of diverse detection scenarios. To address these issues, this invention adopts a convenient gas collection nozzle replacement structure. When the gas collection nozzle needs to be replaced, pulling it causes the latch on one side of the nozzle to engage the first locking shaft under force. The first and second clamping shafts drive the sliders at both ends to slide along the inner wall of the slide groove. After disengaging from the limits of the first and second clamping shafts, the gas collecting nozzle can be disassembled. When the gas collecting nozzle needs to be installed, the air inlet is nested along the air inlet column, and the buckle seat on one side of the gas collecting nozzle is aligned with the middle of the first and second clamping shafts and pressed down, so that the first and second clamping shafts clamp and limit its fixation. This significantly improves the user experience of the combined gas fire detector. This improvement can reduce replacement time and can be completed without complicated tools, so as to quickly switch the gas collecting nozzle type in emergency situations or different detection environments. At the same time, it avoids the loosening or damage of the connection parts caused by frequent disassembly, ensures the sealing and accuracy of the detector, reduces maintenance costs, improves the flexibility and practicality of the equipment, and better adapts to the needs of diverse detection scenarios.
[0007] Preferably, the bottom of the detection console has a second sliding groove, and a sliding seat is slidably connected to the inner wall of the second sliding groove. Multiple casters are fixed to the bottom of the sliding seat, and a support seat is fixed to the inner wall of the second sliding groove. A threaded rod is rotatably connected to the top of the support seat, and the sliding seat is threadedly connected to the surface of the threaded rod. The threaded rod is driven to rotate by a motor, which is fixed to the inner wall of the second sliding groove. In the prior art, combined gas fire detectors often suffer from inconvenience in movement. Their design is mostly fixed installation; once installed in a specific location, moving or rearranging them requires a complex disassembly and reinstallation process, involving rewiring, adjusting sensor positions, etc. This fixed nature makes it difficult to flexibly adjust the device's position according to actual detection needs. For example, when temporary detection of different areas is required or when the spatial layout changes, it cannot respond quickly. Furthermore, frequent disassembly and reassembly can affect the stability and accuracy of the device, increasing maintenance costs and operational difficulty, and limiting its application flexibility in dynamic environments or temporary detection scenarios. To address these problems, this utility model adopts a convenient moving structure. After the motor is started, it drives the threaded rod to rotate. The sliding seat and the threaded rod are connected by a thread. The rotation of the threaded rod causes the sliding seat to move horizontally along the sliding groove. Multiple casters fixed at the bottom of the sliding seat provide support and reduce friction during movement, ensuring that the detection console can move smoothly on the ground. The support seat provides stable rotational support for the threaded rod, enabling the equipment to achieve rapid and flexible positioning and transfer without complicated disassembly and rewiring. This allows the detector to quickly adjust its position according to actual detection needs, responding promptly to both temporary detection and changes in spatial layout. At the same time, it avoids the impact of frequent disassembly and assembly on the stability and accuracy of the equipment, reduces maintenance costs and operational difficulty, and significantly improves the application flexibility and practicality of the equipment in dynamic environments and temporary detection scenarios.
[0008] Preferably, the driving device includes a fixed base fixed to the inner wall of the component slot. A transmission rod is rotatably connected to one side of the fixed base. A first bevel gear is fixed to one end of the transmission rod, and a second bevel gear meshes with the surface of the first bevel gear. The second bevel gear is fixed to one end of a lead screw. The transmission rod is driven to rotate by a second motor, which is fixed to the inner wall of the component slot. This achieves efficient power transmission and precise control, enabling the drive of components connected to the lead screw for position or angle adjustment. Its compact design and stable transmission performance ensure the flexibility and reliability of equipment operation, improving the overall performance and user experience of the combined gas fire detector.
[0009] Preferably, the engaging area of the latching seat has an arc surface, which is smooth. This significantly reduces the friction between the latching seat and the clamping shaft, making the installation and removal of the air collecting nozzle smoother. This design not only reduces wear on components caused by friction and extends the service life of the equipment, but also further improves the convenience of air collecting nozzle replacement, ensuring that there will be no jamming or damage during rapid replacement, thereby improving the efficiency and reliability of the equipment.
[0010] Preferably, the detection console has gripping slots on both sides, and the inner walls of the gripping slots have inclined grooves. This significantly improves the portability and ease of operation of the device. The gripping slots provide users with a stable grip position, facilitating the application of force when moving or adjusting the detection console, while the special design of the inclined grooves further enhances the fit and grip stability of the hand, effectively preventing the device from slipping, especially in wet or emergency situations. This structural optimization not only facilitates the handling and movement of the device but also improves the user's comfort and safety during actual operation, making the combined gas fire detector more flexible and efficient in use.
[0011] Preferably, the sliding seat is X-shaped, and its surface is smooth. This significantly improves the performance of the moving structure of the combined gas fire detector. The X-shaped structure enhances the stability and load-bearing capacity of the sliding seat, ensuring the stability of the detection control console during movement and reducing shaking. The smooth surface reduces the friction between the sliding seat and the second sliding groove, making the movement smoother, reducing wear and energy loss caused by friction, extending the service life of the equipment, and improving moving efficiency and flexibility.
[0012] Beneficial effects:
[0013] 1. In existing technologies, the display screens of combined gas fire detectors present several inconveniences. Firstly, the screen cannot be retracted into the main body, making it susceptible to damage from external impacts during transport or storage, increasing maintenance costs and uncertainty regarding lifespan. Secondly, the screen angle is not adjustable, limiting the user's experience from different viewing angles. For example, when installed at height or used in confined spaces, users need to frequently adjust their posture to see the screen clearly, reducing work efficiency. This fixed screen design cannot meet the needs of diverse scenarios. To address these issues, this invention adopts an adjustable screen angle structure, allowing the display screen to be retracted into the main body and possessing angle adjustment functionality. This effectively solves the problems in existing technologies. The retraction function protects the screen from external impact damage, reducing maintenance costs and extending lifespan; while the angle adjustment function adapts to different viewing angles and usage scenarios, improving user experience and work efficiency, meeting the needs of diverse scenarios, and significantly enhancing the practicality and reliability of the device.

This design is extremely inconvenient in practical use, especially in emergencies or when rapid replacement of the gas collection nozzle is needed to adapt to different detection environments. Frequent disassembly can also lead to loosening or damage of the connection points, affecting the detector's sealing and accuracy. Furthermore, the complexity of the replacement process increases maintenance costs and time, reduces the equipment's flexibility and practicality, and makes it difficult to meet the needs of diverse detection scenarios. To address these issues, this utility model adopts a convenient gas collection nozzle replacement structure, significantly improving the user experience of combined gas fire detectors. This improvement reduces replacement time, allows operation without complex tools, and enables rapid switching of the gas collection nozzle type in emergencies or different detection environments. Simultaneously, it avoids loosening or damage of the connection points caused by frequent disassembly, ensuring the detector's sealing and accuracy, reducing maintenance costs, improving the equipment's flexibility and practicality, and better adapting to the needs of diverse detection scenarios.
[0015] 3. In existing technologies, modular gas fire detectors typically suffer from inconvenience in relocation. Their designs are mostly fixed installations, and once installed in a specific location, moving or rearranging them requires complex disassembly and reinstallation processes, involving rewiring and adjusting sensor positions. This fixed nature makes it difficult to flexibly adjust the device's position according to actual detection needs. For example, when temporary detection of different areas is required or when the spatial layout changes, it cannot respond quickly. Furthermore, frequent disassembly and reassembly can affect the stability and accuracy of the device, increasing maintenance costs and operational difficulty, and limiting its application flexibility in dynamic environments or temporary detection scenarios. To address these issues, this utility model adopts a convenient mobile structure, enabling the device to achieve rapid and flexible positioning and relocation without complex disassembly, reassembly, and rewiring. This allows the detector to quickly adjust its position according to actual detection needs, responding promptly to both temporary detection and changes in spatial layout. Simultaneously, it avoids the impact of frequent disassembly and reassembly on the device's stability and accuracy, reduces maintenance costs and operational difficulty, and significantly improves the device's application flexibility and practicality in dynamic environments and temporary detection scenarios.

However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.
[0027] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific implementation examples:
[0029] Reference Figure 1-8A combined gas fire detector includes a detection console 1, a display screen 101 on the top of the detection console 1, multiple gas collecting nozzles 102 on one side of the detection console 1, and a component slot 103 on the top of the detection console 1. A support plate 104 and a support plate 105 are fixed to the inner wall of the component slot 103. A lead screw 106 is rotatably connected to one side of the support plate 104 and the support plate 105. A sliding rod 107 is fixed to one side of the support plate 104 and the support plate 105. A driving component 108 is threaded onto the surface of the lead screw 106. Driving rods 109 are rotatably connected to both sides of the driving component 108. Driving blocks 110 are rotatably connected to one side of the two driving rods 109. Two support blocks 111 are fixed to the inner wall of the component slot 103. The display screen 101 is rotatably connected to one side of the support block 111. The driving block 110 is fixed to the bottom of the gas collecting nozzle 102. The lead screw 106 is driven to rotate by a driving device. In existing technologies, the display screens of combined gas fire detectors present several inconveniences. Firstly, the screen cannot be retracted into the main unit, making it susceptible to damage from external impacts during transport or storage, increasing maintenance costs and uncertainty regarding its lifespan. Secondly, the screen angle is not adjustable, limiting the user's experience from different viewing angles. For example, when installed at height or used in confined spaces, users need to frequently adjust their posture to see the screen clearly, reducing work efficiency. This fixed screen design cannot meet the needs of diverse scenarios. To address the usage requirements and such issues, this utility model adopts a screen angle adjustable structure. When the drive device is started, the lead screw 106 begins to rotate under the support of the first support plate 104 and the second support plate 105. The drive component 108 on the lead screw 106 moves along the lead screw through a threaded connection. The drive rods 109 on both sides of the drive component 108 swing accordingly, thereby driving the drive block 110 to move along the sliding rod 107. The drive block 110 is connected to the rotation connection point of the display screen 101. Its movement will push the display screen 101 to rotate around the support block 111, thereby realizing the flexible adjustment of the display screen angle.
[0030] The detection control console 1 has multiple air intake columns 2 on one side, and multiple air collection nozzles 102 are all connected inside with air intake holes 201. The air intake columns 2 are located on the inner wall of the air intake holes 201. Each of the multiple air collection nozzles 102 has a locking seat 202 fixed on one side. The detection control console 1 has multiple locking grooves 203 on one side. The inner wall of the locking groove 203 has a sliding groove 204. The inner wall of the locking groove 203 has a first locking shaft 205 and a second locking shaft 206. Both ends of the first locking shaft 205 and the second locking shaft 206 are fixed with sliders 207. The sliders 207 slide on the inner wall of the sliding groove 204. Both ends of the sliders 207 are fixed with springs 208. The other end of the springs 208 is fixed to the inner wall of the sliding groove 204. In existing technologies, the gas collection nozzle of combined gas fire detectors suffers from inconvenient replacement. Because the connection between the gas collection nozzle and the detection control console is relatively fixed, replacement typically requires complex disassembly procedures and specialized tools. This design is extremely inconvenient in practical use, especially in emergencies or when rapid nozzle replacement is needed to adapt to different detection environments. Frequent disassembly can also lead to loosening or damage to the connection points, affecting the detector's sealing and accuracy. Furthermore, the complexity of the replacement process increases maintenance costs and time, reduces the equipment's flexibility and practicality, and makes it difficult to meet the needs of diverse detection scenarios. To address these issues, this utility model adopts a convenient gas collection nozzle... When the air collecting nozzle 102 needs to be replaced, pull the air collecting nozzle 102. Under the action of force, the latch seat 202 on one side of the air collecting nozzle 102 causes the first clamping shaft 205 and the second clamping shaft 206 to drive the sliders 207 at both ends to slide on the inner wall of the slide groove 204. After disengaging from the limit of the first clamping shaft 205 and the second clamping shaft 206, the air collecting nozzle 102 can be disassembled. When the air collecting nozzle 102 needs to be installed, nest the air inlet 201 along the air inlet column 2, align the latch seat 202 on one side of the air collecting nozzle 102 with the middle of the first clamping shaft 205 and the second clamping shaft 206 and press it down so that the first clamping shaft 205 and the second clamping shaft 206 lock and limit its fixation.
[0031] The bottom of the detection control console 1 is provided with a slide groove 2 3. A sliding seat 301 is slidably connected to the inner wall of the slide groove 2 3. Multiple universal wheels 302 are fixed at the bottom of the sliding seat 301. A support seat 303 is fixed to the inner wall of the slide groove 2 3. A threaded rod 304 is rotatably connected to the top of the support seat 303. The sliding seat 301 is threadedly connected to the surface of the threaded rod 304. The threaded rod 304 is driven to rotate by a motor 1 305. The motor 1 305 is fixed to the inner wall of the slide groove 2 3. In existing technologies, combined gas fire detectors often suffer from inconvenience in movement. Their designs are mostly fixed installations, and once installed in a specific location, moving or rearranging them requires complex disassembly and reinstallation processes, involving rewiring, adjusting sensor positions, and other operations. This fixed nature makes it difficult to flexibly adjust the device's position according to actual detection needs. For example, when temporary detection of different areas is required or when the spatial layout changes, it cannot respond quickly. Furthermore, frequent disassembly and reassembly can affect the stability and accuracy of the device, increasing maintenance costs and operational difficulty, and limiting its application flexibility in dynamic environments or temporary detection scenarios. To address these issues, this invention adopts a convenient movement structure. After the motor 305 starts, it drives the threaded rod 304 to rotate. Since the sliding seat 301 and the threaded rod 304 are connected by threads, the rotation of the threaded rod will cause the sliding seat to move horizontally along the sliding groove 3. Multiple universal wheels 302 fixed at the bottom of the sliding seat 301 provide support and reduce friction during movement, ensuring that the detection control console 1 can move smoothly on the ground. The support seat 303 provides stable rotational support for the threaded rod 304.
[0032] The drive device includes a fixed base 4, which is fixed to the inner wall of the component slot 103. A transmission rod 401 is rotatably connected to one side of the fixed base 4. A first bevel gear 402 is fixed to one end of the transmission rod 401, and a second bevel gear 403 meshes with the surface of the first bevel gear 402. The second bevel gear 403 is fixed to one end of the lead screw 106. The transmission rod 401 is driven to rotate by a second motor 404, which is fixed to the inner wall of the component slot 103. This achieves efficient power transmission and precise control, enabling the drive of components connected to the lead screw to perform position or angle adjustments. The compact design and stable transmission performance ensure the flexibility and reliability of equipment operation, improving the overall performance and user experience of the combined gas fire detector. The latch seat 202 has a smooth, arc-shaped surface 5 at the engagement point, which significantly reduces the friction between the latch seat and the clamping shaft, making the installation and removal of the gas collector nozzle smoother. This design not only reduces wear on components caused by friction, extending the equipment's service life, but also further improves the ease of replacing the gas collector nozzle, ensuring that there is no jamming or damage during rapid replacement, thus enhancing... The improved efficiency and reliability of the equipment are achieved by providing gripping grooves 6 on both sides of the detection control console 1, with inclined grooves on the inner walls of the gripping grooves 6. This significantly enhances the portability and ease of operation of the equipment. The gripping grooves provide users with a stable grip, facilitating the application of force when moving or adjusting the detection control console. The special design of the inclined grooves further enhances the fit and grip stability of the hand, effectively preventing the equipment from slipping, especially in wet or emergency situations. This structural optimization not only facilitates the handling and movement of the equipment but also improves the comfort and safety of users during actual operation, making the combined gas fire detector more flexible and efficient in use. The sliding seat 301 is X-shaped with a smooth surface, which significantly improves the performance of the moving structure of the combined gas fire detector. The X-shaped structure enhances the stability and load-bearing capacity of the sliding seat, ensuring the stability of the detection control console during movement and reducing shaking. The smooth surface reduces the friction between the sliding seat and the sliding groove 2, making the movement smoother, reducing wear and energy loss caused by friction, extending the service life of the equipment, and improving the moving efficiency and flexibility.
[0033] The working principle of this utility model is as follows: When the drive device is started, the lead screw 106 begins to rotate under the support of the first support plate 104 and the second support plate 105. The drive component 108 on the lead screw 106 moves along the lead screw through a threaded connection. The drive rods 109 on both sides of the drive component 108 swing accordingly, thereby driving the drive block 110 to move along the sliding rod 107. The drive block 110 is connected to the rotation connection point of the display screen 101. Its movement will push the display screen 101 to rotate around the support block 111, thereby realizing the flexible adjustment of the display screen angle. When it is necessary to replace the air collecting nozzle 102, the air collecting nozzle 102 is pulled, so that the latch seat 202 on one side of the air collecting nozzle 102, under the action of force, causes the first clamping shaft 205 and the second clamping shaft 206 to drive the sliders 207 at both ends to slide on the inner wall of the first slide groove 204, disengaging from the first clamping shaft 205. 5. After the second clamping shaft 206 is limited, the air collecting nozzle 102 can be disassembled. When the air collecting nozzle 102 needs to be installed, the air inlet 201 is nested along the air inlet column 2. The buckle seat 202 on one side of the air collecting nozzle 102 is aligned with the middle of the first clamping shaft 205 and the second clamping shaft 206 and pressed down so that the first clamping shaft 205 and the second clamping shaft 206 clamp and limit and fix it. After the motor 1 305 is started, it drives the threaded rod 304 to rotate. Since the sliding seat 301 and the threaded rod 304 are connected by threads, the rotation of the threaded rod will drive the sliding seat to move horizontally along the slide groove 2 3. The multiple universal wheels 302 fixed at the bottom of the sliding seat 301 provide support and reduce friction during the movement, ensuring that the detection control console 1 can move smoothly on the ground. The support seat 303 provides stable rotation support for the threaded rod 304.
