Description

Technical Field

[0001] This utility model relates to the field of controller technology, and in particular to a fire interface controller. Background Technology

[0002] As the core relay device of the fire alarm control system, the fire alarm interface controller plays a crucial role in connecting the fire alarm host with various fire alarm linkage devices. It must receive, convert, transmit, and control fire alarm signals to ensure accurate and coordinated response from all linkage devices during a fire, safeguarding personnel evacuation and property safety. With increasingly stringent building fire safety requirements, the application scenarios for fire alarm interface controllers are becoming increasingly widespread, covering various locations such as commercial complexes, high-rise buildings, industrial plants, and underground parking garages. These scenarios place higher demands on the controller's ease of installation, maintenance efficiency, and long-term operational stability. Especially during the equipment installation and commissioning phase and subsequent maintenance, the connection method between the controller and the installation carrier directly affects construction efficiency and operation and maintenance costs. Currently, most mainstream fire-fighting interface controllers on the market employ either direct screw fixing or a mechanical structure with cabinet rails and screws for auxiliary fixing during installation. The direct screw fixing structure requires pre-drilling mounting holes in the wall or equipment cabinet. After aligning the controller body with the mounting surface, 4-6 screws are passed sequentially through the mounting ears on the controller housing and the mounting holes in the wall or cabinet, and then tightened to secure the device. The cabinet rail and screw-assisted fixing structure requires first fixing a standard rail inside the cabinet with screws. Then, the rail slot on the bottom of the controller body is aligned with the rail and slid in. Finally, 2-3 screws are passed through the positioning holes on the side wall of the controller and the limiting holes on the rail to lock the device in place. From a technical perspective, existing structures rely on the mechanical compression of the screws. The interlocking friction between the screws and the threaded holes achieves relative fixation between the controller body and the mounting carrier, ensuring that the equipment will not shift due to vibration, external force, or other factors during long-term use, thus guaranteeing the stability of signal transmission and control functions.

[0003] However, the screw-fixing structure used in existing fire interface controllers has significant drawbacks in actual installation and subsequent maintenance: during installation, workers must hold the controller, align it with the preset holes, and simultaneously screw in the screws one by one with a screwdriver. If the installation location is at a height or in a confined space, this is extremely difficult for a single person, requiring multiple people to work together to align the holes and tighten the screws, resulting in low installation efficiency. Later, when disassembly is required for equipment maintenance, replacement, or relocation, the screws must be unscrewed one by one with a screwdriver. If the screws become rusted or stripped after long-term use, additional tools are needed to further extend the disassembly time, making maintenance work cumbersome and time-consuming. This seriously affects the maintenance response speed of the fire protection system and fails to meet the actual needs of rapid deployment and efficient maintenance of fire protection equipment. Therefore, a fire interface controller is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a fire interface controller, which aims to improve the problem that the installation and disassembly of the fire interface controller in the prior art requires tightening screws one by one, which is cumbersome and inefficient.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A fire-fighting interface controller includes a controller body, a door panel rotatably connected to the side wall of the controller body, a control panel disposed inside the door panel, electronic components disposed inside the controller body, an installation assembly disposed on the side wall of the controller body, and a heat dissipation assembly disposed inside the controller body. The mounting assembly includes a mounting bracket and a slider. The mounting bracket is disposed on the side wall of the controller body. The side wall of the slider is fixedly connected to the side wall of the controller body and slidably connected to the inside of the mounting bracket. A fixing shell is fixedly connected to the side wall of the mounting bracket. A fixing rod is slidably connected inside the fixing shell. A pull ring is rotatably connected to one end of the fixing rod. A fixing ring is fixedly connected to the side wall of the fixing rod. A spring is sleeved on the side wall of the fixing rod. One end of the spring is fixedly connected to the inside of the fixing shell, and the other end of the spring is fixedly connected to the side wall of the fixing ring.

[0006] As a further description of the above technical solution: The heat dissipation assembly includes a mounting panel and heat dissipation holes. The side wall of the mounting panel is fixedly connected to the inside of the controller body, the heat dissipation holes are opened inside the mounting panel, and the side wall of the electronic component is fixedly connected to the side wall of the mounting panel.

[0007] As a further description of the above technical solution: The side wall of the fixing rod is slidably connected inside the slider, and the side wall of the fixing ring is slidably connected inside the fixing shell.

[0008] As a further description of the above technical solution: The mounting bracket has a fixed column fixedly connected to its side wall, and a limit plate is rotatably connected to the side wall of the fixed column. The limit plate has a positioning rod on its side wall.

[0009] As a further description of the above technical solution: When the fixing rod is pulled out, the inner wall of the limiting plate fits against the side wall of the fixing rod, and the side wall of the positioning rod slides into the interior of the fixing rod.

[0010] As a further description of the above technical solution: The mounting panel is fixedly connected to a heat dissipation fin, and the controller body has an air outlet on the top, with the heat dissipation fin located below the air outlet.

[0011] As a further description of the above technical solution: The controller body has two air inlets at its bottom, which are symmetrically distributed on the left and right sides.

[0012] As a further description of the above technical solution: A filter is provided on the top of the controller body, and the filter is located outside the air outlet.

[0013] As a further description of the above technical solution: The controller body has two filters at its bottom, and the two filters are located outside the two air inlets respectively.

[0014] As a further description of the above technical solution: The controller body is equipped with a magnetic block 1 inside, and both the filter screen 1 and the filter screen 2 are equipped with magnetic blocks 2 inside. The magnetic block 1 and the magnetic block 2 attract each other.

[0015] This utility model has the following beneficial effects: 1. In this utility model, by pulling the pull ring, the fixed rod and the fixed ring are compressed and disengaged from the slider. Then, the limiting plate on the fixed column is rotated to make the positioning rod slide into the hole of the fixed rod and keep it in a retracted state. This achieves the effect of quick separation between the controller body and the mounting bracket, solving the problem that the installation and disassembly of the existing fire interface controller requires tightening screws one by one, which is cumbersome and inefficient. The above structure improves the convenience of controller installation and subsequent maintenance and adjustment, and disassembly and assembly can be completed without tools.

[0016] 2. In this utility model, heat is transferred to the mounting panel through electronic components, which drives the heat dissipation fins on the back of the mounting panel to diffuse heat and the heat dissipation holes to accelerate the flow of hot air. At the same time, the air inlet at the bottom of the controller body introduces cold air and the air outlet at the top discharges hot air, forming natural convection. In addition, filter screen one and filter screen two block dust, and the filter screens can be removed and installed without tools through magnetic blocks one and two. This achieves the dual effect of efficient heat dissipation and convenient filter maintenance, solving the problems of low heat dissipation efficiency and tool-required and cumbersome operation of existing fire interface controllers. The above structure improves the operational stability of the electronic components inside the controller and the efficiency of filter maintenance. Attached Figure Description

Detailed Implementation

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.

[0020] Reference Figures 1-5 This utility model provides an embodiment of a fire interface controller, including a controller body 1. A door panel 2 is rotatably connected to the side wall of the controller body 1. A control panel 3 is set inside the door panel 2. The control panel 3 adopts an embedded touch panel of model STM32F103, which is used to display the operating status of the electronic components inside the controller body 1, such as equipment operating parameters, fault alarm information, etc. It also supports manual input of control commands by the staff to start or stop the linkage equipment, set parameters, etc., which are common knowledge and will not be described in detail here. The controller body 1 is equipped with electronic components, including a communication module of model RS485 and a microcontroller chip of model ATMEGA128, to achieve the core effect of receiving, converting, transmitting and controlling fire signals. This will not be described in detail here. The side wall of the controller body 1 is equipped with an installation component for fixing the controller body 1 to the wall to achieve the effect of stable installation of equipment. The controller body 1 is equipped with a heat dissipation component for dissipating the heat generated by the operation of electronic components to ensure that the electronic components operate stably at a suitable temperature. The mounting assembly includes a mounting bracket 4 and a slider 5. The mounting bracket 4 is located on the side wall of the controller body 1. The side wall of the slider 5 is fixedly connected to the side wall of the controller body 1. The slider 5 works in conjunction with the mounting bracket 4 to achieve sliding positioning of the controller body 1. The side wall of the slider 5 is slidably connected inside the mounting bracket 4. The slider 5 moves in conjunction with the mounting bracket 4 to achieve the effect of quickly aligning the controller body 1 with the installation position. A fixing shell 6 is fixedly connected to the side wall of the mounting bracket 4. A fixing rod 7 is slidably connected inside the fixing shell 6. The fixing rod 7 is inserted into the slider 5 to lock the slider 5 to the mounting bracket 4. A pull ring 8 is rotatably connected to one end of the fixing rod 7. The pull ring 8 provides a force application point for the operator to easily pull the fixing rod. 7. Unlocking operation is performed to achieve convenient control of the movement of the fixed rod 7. The fixed rod 7 is fixedly connected to the side wall of the fixed rod 7 and a spring 9 is sleeved on the side wall of the fixed rod 7. The function of the spring 9 is to provide the fixed rod 7 with the return elastic force. When there is no external force pulling the pull ring 8, the elastic force of the spring 9 pushes the fixed ring 10 to drive the fixed rod 7 to move towards the slider 5, thereby achieving the effect of automatically locking the slider 5. One end of the spring 9 is fixedly connected to the inside of the fixed shell 6, and the other end of the spring 9 is fixedly connected to the side wall of the fixed ring 10. The side wall of the fixed rod 7 is slidably connected to the inside of the slider 5, and cooperates with the slider 5 to perform the insertion and removal movement, thereby achieving the effect of locking or unlocking the connection between the slider 5 and the mounting bracket 4. The side wall of the fixed ring 10 is slidably connected to the inside of the fixed shell 6. The mounting bracket 4 has a fixed column 11 fixedly connected to its side wall. The side wall of the fixed column 11 is rotatably connected to a limit plate 12. The limit plate is used to limit and fix the fixed rod 7 when it is pulled out. The side wall of the limit plate 12 is provided with a positioning rod. The positioning rod is inserted into the fixed rod 7 to fix the limit plate 12 and the fixed rod 7. When the fixed rod 7 is pulled out, the inner wall of the limit plate 12 fits against the side wall of the fixed rod 7, and the side wall of the positioning rod slides into the fixed rod 7 to cooperate with the fixed rod 7 to perform a locking movement. This achieves the effect of keeping the fixed rod 7 in the retracted state and preventing the spring 9 from pushing the fixed rod 7 to reset. This allows the operator to easily pull out the slider 5 to complete the disassembly of the controller body 1.

[0021] Reference Figure 2 and Figure 6The heat dissipation assembly includes a mounting panel 13 and heat dissipation holes 14. The sidewall of the mounting panel 13 is fixedly connected to the inside of the controller body 1. The mounting panel 13 serves to support electronic components and transfer the heat generated by them. The heat dissipation holes 14 are circular through holes with a diameter of 3mm, arranged in a matrix, which are used to accelerate the flow of hot air on the surface of electronic components, thereby assisting in heat dissipation and improving the heat dissipation efficiency of the mounting panel 13. The sidewall of the electronic component is fixedly connected to the sidewall of the mounting panel 13, working together with the mounting panel 13 to conduct heat, achieving the effect of quickly transferring the heat generated by the operation of the electronic component to the mounting panel 13. The back of the mounting panel 13 is fixedly connected to... The controller body 1 is equipped with heat dissipation fins 15, which are made of 6063 aluminum alloy and are connected to the mounting panel 13 using an integrated molding process. The purpose of these fins is to increase the heat dissipation area and accelerate the diffusion of heat from the mounting panel 13 to the surrounding air, thereby enhancing heat dissipation. The top of the controller body 1 has an air outlet 17, which is an elongated hole used to expel hot air from inside the controller body 1, guiding the hot airflow and ensuring unobstructed heat dissipation. The heat dissipation fins 15 are located below the air outlet 17, working in conjunction with the air outlet 17 to guide the hot airflow, allowing the hot air around the heat dissipation fins 15 to be quickly expelled through the air outlet 17. The bottom of the controller body 1 has two... There is one air inlet 16, which is a long, narrow hole symmetrically distributed on the left and right sides. It is used to introduce external cold air to supplement the cold air and create convection. The top of the controller body 1 is equipped with a filter screen 18, which is made of ABS plastic frame and nylon mesh with a mesh count of 100. The function of the filter screen 18 is to filter dust in the air entering the air outlet 17, preventing dust from entering the controller body 1 and adhering to the surface of the heat sink fins 15. The filter screen 18 is located outside the air outlet 17 and works with the air outlet 17 to filter dust, achieving the effect of blocking dust intrusion without affecting the exhaust of hot air. The bottom of the controller body 1 is equipped with two filters 20. The filters 0 are located outside the two air inlets 16, respectively, and work with the air inlets 16 to filter dust, achieving the effect of filtering dust from the cold air entering the air inlets 16. The second filter 20 is made of nylon mesh with a mesh count of 100 mesh, which further filters fine dust in the air, achieving a double dustproof effect. The controller body 1 has a magnetic block 19 inside, and both the first filter 18 and the second filter 20 have a magnetic block 21 inside. The magnetic block 19 and the magnetic block 21 attract each other. Both the magnetic block 19 and the magnetic block 21 are made of neodymium iron boron strong magnets, which are used to fix and remove the filters, achieving the effect of quickly removing the filters for cleaning or replacement without tools, simplifying the maintenance process.

[0022] Working principle: When installing the equipment, first fix the mounting bracket 4 to the wall, align the slider 5 on the side wall of the controller body 1 with the slide groove of the mounting bracket 4, slide along the slide groove to make the body 1 fit against the mounting bracket 4, at this time the positioning hole of the slider 5 is aligned with the hole of the fixing shell 6 on the side wall of the mounting bracket 4. At this time, the spring 9 inside the fixed shell 6 is in a naturally extended state, pushing the fixed ring 10 and the fixed rod 7 fixed thereto to slide towards the slider 5. One end of the fixed rod 7 slides into the slider 5, locking the slider 5 and the mounting bracket 4, thus fixing the controller body 1. When the controller needs to be disassembled or adjusted, pull the pull ring 8 at the end of the fixing rod 7. The fixing rod 7 drives the fixing ring 10 to compress the spring 9 and disengage from the slider 5. At this time, rotate the limiting plate 12 on the side wall fixing column 11 of the mounting bracket 4 so that the inner wall of the limiting plate 12 fits against the side wall of the fixing rod 7, and the positioning rod on the limiting plate 12 slides into the corresponding hole of the fixing rod 7, keeping the fixing rod 7 in the retracted state. Then the slider 5 can be pulled out along the slide groove to separate the controller body 1 from the mounting bracket 4. When the equipment is running, staff can set parameters and issue manual commands through the control panel 3 inside the door panel 2, such as manually starting the smoke exhaust fan and resetting fault signals. At the same time, the control panel 3 can display the equipment status information transmitted by the electronic components in real time. The internal electronic components convert the received external signals, such as switch signals and analog signals, into standardized control signals and transmit them to the fire linkage equipment, such as sprinkler pumps and fire door controllers, to drive the linkage equipment to perform corresponding actions, such as starting the sprinkler and closing the fire door. The action status signal of the linkage equipment is transmitted back to the electronic components inside the controller body 1, and after processing, it is displayed through the control panel 3 or uploaded to the fire control panel to form a closed-loop control. Electronic components are fixed to the side wall of mounting panel 13, and the heat generated during operation is directly transferred to mounting panel 13. The heat dissipation fins 15 on the back of mounting panel 13 increase the heat dissipation area and quickly diffuse the heat of mounting panel 13 to the surrounding air. At the same time, the heat dissipation holes 14 inside mounting panel 13 can accelerate the flow of hot air on the surface of electronic components to the heat dissipation fins 15 area, supplementing the conduction path. Two symmetrical air inlets 16 at the bottom of controller body 1 introduce external cold air. When the cold air flows through the heat dissipation fins 15, it absorbs heat and becomes hot air. The hot air flows upward due to its lower density and is discharged through the air outlet 17 at the top of body 1, forming a natural convection circulation of "bottom in and top out", which continuously removes internal heat. The filter 18 outside the air outlet 17 and the filter 20 outside the air inlet 16 can prevent dust in the air from entering the interior of body 1, avoiding dust from adhering to the heat dissipation fins 15 or the surface of electronic components and affecting heat dissipation. Filter 18 is fixed to the internal magnetic block 19 inside the controller body 1 via internal filter 20. During maintenance, simply pull filter 18 outward to detach filter 20 from magnetic block 19, allowing the filter to be removed for cleaning or replacement. After cleaning, align filter 20 with magnetic block 19 and reset it via magnetic attraction. Filter 20 on the air inlet side is fixed to magnetic block 21, which is also attracted to the outer shell of the body 1. During disassembly, pull filter 20 outward to detach it from magnetic block 21, clean it, and then reattach it. No tools are required, greatly simplifying the maintenance process.
