Description

Technical Field

[0001] This utility model relates to the field of smoke detector technology, and in particular to a smoke detector that is easy to install and disassemble. Background Technology

[0002] Smoke detectors, also known as smoke-sensing alarms, are key front-end devices in fire alarm systems. They primarily use built-in sensors to monitor the smoke concentration in the environment in real time, playing a vital role in modern building fire safety systems. Before installing a smoke detector, a compatible mounting bracket is usually bolted to it, and then the smoke detector is installed on the bracket. The installation location is often in a high position such as the ceiling.

[0003] Regarding the aforementioned and existing related technologies, the inventor believes that the following drawbacks often exist: the installation of traditional smoke detectors often requires operators to use disassembly and assembly tools to tighten several screws onto the mounting base to secure it. When routine operations such as maintenance, repair, or battery replacement are required, especially when operating at heights, not only are specialized tools needed, but construction personnel are also required to carry heavy disassembly and assembly equipment to climb to high places to work. The operation process is extremely cumbersome and consumes a lot of time and manpower. Therefore, to address the above problems, an easy-to-disassemble smoke detector is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where the installation of traditional smoke detectors often requires operators to use disassembly and assembly tools to tighten several screws onto the mounting base for fixation. When routine operations such as maintenance, repair, or battery replacement are needed, especially when operating at heights, not only are specialized tools required, but workers are also required to carry heavy disassembly and assembly equipment to climb to high places for operation. This process is extremely cumbersome and consumes a lot of time and manpower. Therefore, this invention proposes a smoke detector that is easy to disassemble and assemble.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a smoke detector that is easy to assemble and disassemble, comprising a mounting base, wherein the surface of the mounting base is provided with a plurality of mounting holes, a circular ring frame is fixedly connected to the surface of the mounting base, a smoke detector body is slidably connected to the inner wall of the circular ring frame, two grooves are provided on the inner wall of the circular ring frame, a fixing block is fixedly connected to the lower end of the smoke detector body, a mounting groove is provided on one side of the fixing block, two threaded rods are rotatably connected inside the circular ring frame, the threaded rods pass through the grooves, the arc surface of the threaded rods is threadedly connected to the mounting block, the mounting block is slidably connected to the inner wall of the groove, the size of the mounting block is adapted to the size of the mounting groove, and a circular shaft is fixedly connected to the ends of the two threaded rods that are far apart from each other.

[0006] The aforementioned components achieve the following effect: They facilitate easy assembly and disassembly of the smoke detector body. During installation, the smoke detector body is slid along the inner wall of the ring frame. Then, the threaded rod is rotated, causing the mounting block, threaded onto the rod, to slide within the groove. Utilizing the dimensional fit between the mounting block and the mounting groove, the mounting block slides into the groove, securely connecting the smoke detector body to the ring frame, completing the installation. When disassembly is required, the threaded rod is rotated in the opposite direction, causing the mounting block to slide out of the groove, allowing for easy removal of the smoke detector body. This avoids the complex installation and disassembly methods of traditional smoke detectors, greatly improving the convenience of installation and disassembly. It also facilitates rapid maintenance, repair, and replacement of the smoke detector body in the future, effectively saving manpower and time costs.

[0007] Preferably, the inner wall of the groove has two square slots, and the inner walls of the two square slots are slidably connected to a sliding plate, one side of which is fixedly connected to the mounting block.

[0008] The effect achieved by the above components is as follows: by guiding and limiting the sliding plate through the square groove, it can ensure that the mounting block slides smoothly in the groove in a predetermined direction under the drive of the threaded rod, avoiding the mounting block from shaking or shifting, thereby more accurately matching the mounting groove and improving the stability and reliability of the smoke detector body during installation and disassembly.

[0009] Preferably, the circular surface of the circular shaft is provided with a plurality of anti-slip grooves, and the plurality of anti-slip grooves are evenly distributed on the circular surface of the circular shaft.

[0010] The effect achieved by the above components is as follows: the anti-slip groove increases the friction of the circular arc surface of the shaft, making it less likely for the operator's fingers to slip when rotating the shaft to drive the threaded rod. This allows for easier, more stable, and more precise force application to rotate the shaft, thereby smoothly moving the mounting block and completing the installation and disassembly of the smoke detector body.

[0011] Preferably, the bottom surface of the groove is provided with a placement slot, the size of which is adapted to the size of the fixing block.

[0012] The effect achieved by the above components is that when installing the smoke detector body, the fixing block can fall precisely into the placement groove, providing positioning and support for the installation of the smoke detector body, and making it more stable after installation.

[0013] Preferably, a plurality of ball bearings are mounted on the lower surface of the mounting block, and the ball bearings are slidably connected to the bottom surface of the groove.

[0014] The effect achieved by the above components is that the ball bearings can significantly reduce the friction when the mounting block slides in the groove, making the movement of the mounting block smoother.

[0015] Preferably, the circular arc surface of the ring frame is provided with a plurality of ventilation holes, and the plurality of ventilation holes are evenly distributed on the circular arc surface of the ring frame.

[0016] The effects achieved by the above components are as follows: the vents allow the smoke detector to be more sensitive to smoke and respond more promptly, enabling the smoke detector to fully diffuse the detection area, thus improving the accuracy and timeliness of fire warnings. At the same time, the components generate heat during operation, and the vents facilitate heat dissipation, preventing excessive temperature from affecting performance and ensuring that the alarm can detect smoke normally.

[0017] In summary, the beneficial effects of this utility model are as follows:

[0018] This invention facilitates easy assembly and disassembly of the smoke detector body. During installation, the smoke detector body is slid along the inner wall of the ring frame. Then, the threaded rod is rotated, causing the mounting block, threaded onto the rod, to slide within the groove. Utilizing the dimensional fit between the mounting block and the mounting groove, the mounting block slides into the groove, securely connecting the smoke detector body to the ring frame, completing the installation. When disassembly is required, the threaded rod is rotated in the opposite direction, allowing the mounting block to slide out of the groove, making it easy to remove the smoke detector body. This design avoids the complex assembly and disassembly methods of traditional smoke detectors, greatly improving the convenience of installation and disassembly. It also facilitates rapid maintenance, repair, and replacement of the smoke detector body in the future, effectively saving manpower and time costs. Attached Figure Description

[0024] Reference Figures 1-4As shown, this utility model provides a technical solution: a smoke detector that is easy to assemble and disassemble, including a mounting base 1. The surface of the mounting base 1 has several mounting holes. A circular ring frame 2 is fixedly connected to the surface of the mounting base 1. A smoke detector body 3 is slidably connected to the inner wall of the circular ring frame 2. Two grooves 4 are formed in the inner wall of the circular ring frame 2. A fixing block 5 is fixedly connected to the lower end of the smoke detector body 3. A mounting groove 6 is formed on one side of the fixing block 5. Two threaded rods 7 are rotatably connected inside the circular ring frame 2. The threaded rods 7 pass through the grooves 4. A mounting block 9 is threadedly connected to the arc surface of the threaded rod 7. The mounting block 9 is slidably connected to the inner wall of the groove 4. The size of the mounting block 9 is... The mounting slot 6 is sized to fit the smoke detector, and the ends of the two threaded rods 7 that are far apart from each other are fixedly connected to a round shaft 8, which facilitates the operator's disassembly and assembly of the smoke detector body 3. During installation, the smoke detector body 3 is slid along the inner wall of the ring frame 2, and then the threaded rod 7 is rotated to make the mounting block 9, which is threaded onto the threaded rod 7, slide in the groove 4. Taking advantage of the size fit between the mounting block 9 and the mounting slot 6, the mounting block 9 slides into the mounting slot 6, which can securely connect the smoke detector body 3 and the ring frame 2, thus completing the installation. When disassembly is required, the threaded rod 7 is rotated in the opposite direction to make the mounting block 9 slide out of the mounting slot 6, and the smoke detector body 3 can be easily removed.This design avoids the complex installation and disassembly methods of traditional smoke detectors, greatly improving the convenience of installation and disassembly. It facilitates quick maintenance, repair, and replacement of the smoke detector body 3, effectively saving manpower and time costs. Two square grooves 10 are formed on the inner wall of the groove 4, with a sliding plate 11 slidably connected to the inner wall of each groove 10. One side of the sliding plate 11 is fixedly connected to the mounting block 9. The square grooves 10 guide and limit the sliding plate 11, ensuring that the mounting block 9 slides smoothly in the groove 4 in a predetermined direction under the drive of the threaded rod 7, preventing the mounting block 9 from shaking or shifting. This allows for more precise matching with the mounting groove 6, improving the stability and reliability of the smoke detector body 3 during installation and disassembly. Several anti-slip grooves 12 are evenly distributed on the arc surface of the round shaft 8, increasing the friction of the arc surface. When the operator rotates the round shaft 8 to drive the threaded rod 7, their fingers are less likely to slip, allowing for easier and more stable operation. The circular shaft 8 is precisely rotated, thus smoothly moving the mounting block 9 and completing the installation and removal of the smoke detector body 3. The bottom surface of the groove 4 has a placement groove 13, the size of which matches the size of the fixing block 5. When installing the smoke detector body 3, the fixing block 5 can accurately fall into the placement groove 13, providing positioning and support for the installation of the smoke detector body 3 and making it more stable after installation. Several ball bearings 14 are installed on the lower surface of the mounting block 9. The ball bearings 14 are slidably connected to the bottom surface of the groove 4. The ball bearings 14 can significantly reduce the friction when the mounting block 9 slides in the groove 4, making the movement of the mounting block 9 smoother. The vent hole 15 allows the smoke detector body 3 to perceive smoke more sensitively and respond more promptly, enabling the smoke detector body 3 to fully diffuse the detection area, improving the accuracy and timeliness of fire warning. At the same time, the components generate heat during operation, and the vent hole 15 facilitates heat dissipation, avoiding excessive temperature from affecting performance and ensuring that the alarm can normally sense smoke.

[0025] Working principle: When installing the smoke detector body 3, the mounting base 1 is first fixed to the target position through the mounting holes on its surface. The smoke detector body 3 slides down the inner wall of the ring frame 2, and the fixing block 5 at its lower end falls into the placement groove 13 on the bottom surface of the groove 4, completing the initial positioning. Then, the operator rotates the round shaft 8 fixedly connected to the threaded rod 7. The anti-slip groove 12 on the round shaft 8 increases the friction to facilitate the application of force. The rotation of the threaded rod 7 drives the mounting block 9 threadedly connected to it. The mounting block 9 cooperates with the square groove 10 on the inner wall of the groove 4 through the sliding plate 11, moving along the predetermined direction. Smooth sliding is achieved by utilizing the size fit between the mounting block 9 and the mounting groove 6 on the fixing block 5, allowing the mounting block 9 to slide into the mounting groove 6, thus securing the smoke detector body 3 to the circular frame 2 and completing the installation. During this process, the ball bearings 14 on the lower surface of the mounting block 9 reduce friction with the groove 4, making the movement of the mounting block 9 smoother. For disassembly, the operator rotates the circular shaft 8 in the opposite direction, causing the threaded rod 7 to reverse, allowing the mounting block 9 to exit from the mounting groove 6 along the square groove 10 under the drive of the threaded rod 7. Then, the smoke detector body 3 can be easily lifted, allowing the fixing block 5 to disengage from the placement groove 13, completing the disassembly. In daily operation, the evenly distributed ventilation holes 15 on the arc surface of the circular frame 2 promote air circulation, allowing smoke to quickly diffuse into the smoke detector body 3, improving the alarm's sensitivity to smoke and enabling timely and accurate alarm activation. At the same time, the ventilation holes 15 help dissipate the heat generated by the operation of electronic components inside the alarm, preventing excessive temperature from affecting the alarm's performance.
