Description

Technical Field

[0001] The utility model relates to the technical field of security equipment, in particular to a smoke detector for building security which is easy to install. Background Art

[0002] Smoke detectors mainly prevent fires by monitoring the concentration of smoke. They are connected to the ceiling or wall of a building through bolts. They are mainly used in fire protection systems and play an important role in the construction of security systems.

[0003] Prior art, such as the Chinese patent publication number CN218069031U, discloses a smoke detector for building security that is easy to install, comprising a mounting base, a smoke detector body mounted on the upper end of the mounting base, and a central axis rod disposed between the mounting base and the smoke detector body. The smoke detector for building security adopts a combined structure of the mounting base and the smoke detector body, which allows maintenance of the internal electronic components without removing it from the mounting wall. It is also more convenient for maintenance to extend the service life of the equipment. The mounting base and the smoke detector body are fixed together by a locking bolt that automatically inserts horizontally into the hole and groove structure on the mounting base and the smoke detector, avoiding the use of bolts for connection, making installation very convenient. However, the utility model is installed and disassembled by bending a rubber rod during use. After repeated use, the rubber rod is easily damaged, resulting in the equipment being unable to be used normally, and the durability is insufficient.

[0004] In order to solve the problem that smoke detectors are difficult to install, most existing smoke detectors are integral structures and are fixed to the wall with multiple bolts. When they need to be repaired or replaced, the entire device often needs to be removed. During the disassembly and installation process, the bolts need to be frequently tightened and loosened, which is quite troublesome. A few non-integrated structures have problems with loose fixation or insufficient durability, so improvements are needed. Utility Model Content

[0005] The purpose of the utility model is to solve the disadvantage of the smoke detectors in the prior art that they are inconvenient to install, and to provide a smoke detector for building security that is easy to install.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a smoke detector for building security that is easy to install, comprising a base, a mounting hole, a smoke detector body, an exchange port and a loading and unloading device, the mounting hole being opened on the surface of the base, the smoke detector body being arranged on the surface of the base through the loading and unloading device, the exchange port being opened on the surface of the smoke detector body, the loading and unloading device being arranged on the surface of the base, the loading and unloading device comprising a connecting platform, the connecting platform being fixedly connected to the surface of the base, the surface of the connecting platform being fixedly connected to a center column, the other end of the center column being fixedly connected to the mounting platform, the surface of the center column being rotatably connected to a turntable, the surface of the turntable being opened with a threaded groove, the surface of the threaded groove being slidably connected with a slider, the surface of the mounting platform being opened with a slide groove, the slider being slidably connected to the surface of the slide groove, the surface of the slider being fixedly connected with a hook, the surface of the smoke detector body being opened with a mounting groove, the surface of the mounting groove being opened with a clamping groove, the clamping hook being slidably connected to the surface of the mounting groove, and the clamping connection being provided with the surface of the clamping groove.

[0007] Furthermore, the end of the slider away from the hook is fixedly connected to a limiting block, the surface of the thread groove is provided with a limiting groove, the limiting block is slidably connected to the surface of the limiting groove, and the limiting groove is spiral and slightly wider than the thread groove.

[0008] Furthermore, a spring is fixedly connected to the surface of the slide groove, the other end of the spring is fixedly connected to the surface of the slider, and a plurality of groups of anti-slip pads are fixedly connected to the surface of the turntable.

[0009] Furthermore, the number of the slider, the sliding groove, the hook, the installation groove, the locking groove, the limit block and the spring are all four groups and are distributed in a circularly symmetrical manner.

[0010] Furthermore, a cleaning device is provided on the surface of the smoke detector body, and the cleaning device includes a rotating shaft, which passes through and is rotatably connected to the inner wall of the smoke detector body. A rotating plate is fixedly connected to the surface of the rotating shaft, and the number of the rotating plates is two groups and is symmetrically arranged.

[0011] Furthermore, a plurality of cleaning blocks are fixedly connected to the surface of the rotating plate, the cleaning blocks are slidably connected to the surface of the exchange port, the surface of the cleaning block is fixedly connected to a cleaning plate, and the cleaning plate is slidably connected to the inner wall of the smoke detector body.

[0012] Furthermore, one end of the rotating shaft away from the smoke detector body is fixedly connected to a rotating disk, and the surface of the rotating disk is provided with anti-slip grooves.

[0013] Compared with the prior art, the advantages and positive effects of the present invention are:

[0014] The four sets of hooks are moved synchronously by rotating the turntable so that the four sets of mounting slots on the smoke detector body are aligned with the four sets of hooks, so that the hooks are inserted into the mounting slots. Then, the turntable is released, and the spring rebounds, so that the four sets of sliders slide along the slide slots toward the center column, thereby causing the four sets of hooks to be locked into the four sets of slots, thereby achieving the installation of the smoke detector body. When the smoke detector body needs to be removed for maintenance or replacement, the turntable only needs to be rotated again so that the hooks are disengaged from the slots and the smoke detector body can be removed downward. By providing the loading and unloading device, the smoke detector body can be conveniently installed and removed, avoiding the cumbersome installation and disassembly process caused by using bolts to fix the entire device during maintenance or replacement, thereby effectively improving the convenience of the device.

[0015] 2. In the present invention, by providing a cleaning device, when the smoke detector body has been used for a long time, the exchange port may be blocked by dust or foreign matter. The turntable can be rotated left and right to make the rotating shaft drive the rotating plate to rotate, thereby making the cleaning block rotate to clean the exchange port. At the same time, the cleaning plate rotates to clean the bottom of the inner wall of the smoke detector body, so that dust and foreign matter fall from the exchange port. By providing a cleaning device, the exchange port and the bottom of the inner wall can be cleaned without disassembling the smoke detector body, thereby preventing dust and foreign matter from blocking the exchange port and causing equipment failure, thereby effectively improving the durability of the equipment.

[0023] See also Figure 1-5 The utility model provides a technical solution: a smoke detector for building security that is easy to install, including a base 1, a mounting hole 2, a smoke detector body 3, an exchange port 4 and a loading and unloading device 5. The mounting hole 2 is opened on the surface of the base 1, the smoke detector body 3 is set on the surface of the base 1 through the loading and unloading device 5, the exchange port 4 is opened on the surface of the smoke detector body 3, and the loading and unloading device 5 is set on the surface of the base 1.

[0024] The specific settings and functions of the loading and unloading device 5 and the cleaning device 6 will be described in detail below.

[0025] In this embodiment: the loading and unloading device 5 includes a connecting platform 501, which is fixedly connected to the surface of the base 1, and a center column 502 is fixedly connected to the surface of the connecting platform 501, and the other end of the center column 502 is fixedly connected to the mounting platform 503, and the surface of the center column 502 is rotatably connected to the turntable 504, and the surface of the turntable 504 is provided with a threaded groove 505, and the surface of the threaded groove 505 is slidably connected to the slider 506, and the surface of the mounting platform 503 is provided with a slide groove 507, and the slider 506 is slidably connected to the surface of the slide groove 507, and the surface of the slider 506 is fixedly connected to the hook 508, and the surface of the smoke detector body 3 is provided with a mounting groove 509, and the surface of the mounting groove 509 is provided with a clamping groove 510, and the hook 508 is slidably connected to the surface of the mounting groove 509, and the hook 508 is clamped and connected to the surface of the clamping groove 510.

[0026] The effect achieved by the above components is as follows: the base 1 is fixed to the wall by bolts and the mounting holes 2. When the smoke detector body 3 needs to be installed, the turntable 504 is first rotated to rotate it along the center column 502. Under the action of the threaded groove 505, the slider 506 slides along the slide groove 507 in the direction away from the center column 502, driving the hook 508 to move synchronously, and then the mounting groove 509 on the smoke detector body 3 is aligned with the hook 508, so that the hook 508 is inserted into the mounting groove 509, and then the slider 506 slides along the slide groove 507 in the direction close to the center column 502, so that the hook 508 is stuck in the slot 510, thereby realizing the installation of the smoke detector body 3. When the smoke detector body 3 needs to be removed for maintenance or replacement, it is only necessary to rotate the turntable 504 again to disengage the hook 508 from the slot 510 and then the smoke detector body 3 can be removed downward.

[0027] Specifically, the end of the slider 506 away from the hook 508 is fixedly connected to the limiting block 512, and a limiting groove 511 is provided on the surface of the thread groove 505. The limiting block 512 is slidably connected to the surface of the limiting groove 511. The limiting groove 511 is spiral and its width is slightly larger than the thread groove 505.

[0028] The effect achieved by the above components is that the limiting groove 511 and the limiting block 512 are provided to prevent the slider 506 from being separated from the turntable 504 without affecting the sliding of the slider 506 .

[0029] Specifically, a spring 513 is fixedly connected to the surface of the slide groove 507 , and the other end of the spring 513 is fixedly connected to the surface of the slider 506 . A plurality of groups of anti-slip pads 514 are fixedly connected to the surface of the turntable 504 .

[0030] The effects achieved by the above components are as follows: the spring 513 is provided so that a certain force needs to be applied when rotating the turntable 504 to avoid accidental touch causing the hook 508 to disengage from the slot 510 and causing the smoke detector body 3 to fall. At the same time, the rebound effect of the spring 513 can be utilized to make the hook 508 slide into the slot 510 more easily and get stuck more stably. The anti-slip pad 514 is provided to facilitate the rotation of the turntable 504.

[0031] Specifically, the number of the slider 506 , the sliding groove 507 , the hook 508 , the installation groove 509 , the locking groove 510 , the limit block 512 and the spring 513 are all four groups and are distributed in a circularly symmetrical manner.

[0032] The effects achieved by the above components are as follows: the four sets of hooks 508 and slots 510 are provided to fix the smoke detector body 3 more stably.

[0033] Specifically, a cleaning device 6 is provided on the surface of the smoke detector body 3. The cleaning device 6 includes a rotating shaft 61. The rotating shaft 61 passes through and is rotatably connected to the inner wall of the smoke detector body 3. A rotating plate 62 is fixedly connected to the surface of the rotating shaft 61. The number of the rotating plates 62 is two groups and they are symmetrically arranged.

[0034] The effect achieved by the above components is that when the rotating shaft 61 rotates, the rotating plate 62 is driven to rotate. Two sets of rotating plates 62 are provided to match the exchange ports 4 on both sides.

[0035] Specifically, the surface of the rotating plate 62 is fixedly connected to multiple groups of cleaning blocks 63, the cleaning blocks 63 are slidably connected to the surface of the exchange port 4, and the surface of the cleaning blocks 63 is fixedly connected to a cleaning plate 64, which is slidably connected to the inner wall of the smoke detector body 3.

[0036] The effect achieved by the above components is: when the rotating plate 62 rotates, the cleaning block 63 slides along the exchange port 4 to clean the dust and foreign matter in the exchange port 4, and at the same time the cleaning plate 64 slides along the bottom of the inner wall of the smoke detector body 3 to clean it, avoiding dust and foreign matter from clogging and causing equipment failure, and the rotating plate 62 and the cleaning plate 64 can cooperate to play a limiting role to prevent the rotating shaft 61 from separating from the smoke detector body 3.

[0037] Specifically, one end of the rotating shaft 61 away from the smoke detector body 3 is fixedly connected to a rotating disk 65 , and an anti-slip groove 66 is provided on the surface of the rotating disk 65 .

[0038] The effects achieved by the above components are as follows: the turntable 65 and the anti-slip grooves 66 are provided to facilitate the rotation of the rotating shaft 61 and avoid slipping during rotation.

[0039] When the smoke detector body 3 needs to be installed, the turntable 504 is first rotated to rotate it along the center column 502. Under the action of the threaded groove 505, the slider 506 slides along the slide groove 507 in the direction away from the center column 502. At the same time, the spring 513 is compressed, driving the four sets of hooks 508 to move synchronously. Then, the four sets of mounting grooves 509 on the smoke detector body 3 are aligned with the four sets of hooks 508, so that the hooks 508 are inserted into the mounting grooves 509. Then, the turntable 504 is released. Under the rebound action of the spring 513, the four sets of sliders 506 slide along the slide groove 507 in the direction close to the center column 502, and then the four sets of hooks 508 are locked in the four sets of slots 510, thereby realizing the installation of the smoke detector body 3. When the smoke detector body 3 needs to be removed for maintenance or replacement, it is only necessary to rotate the turntable 504 again so that the hooks 508 can be disengaged from the card slot 510 to remove the smoke detector body 3 downward. By setting up the loading and unloading device 5, the smoke detector body 3 can be easily installed and disassembled, avoiding the use of bolts to fix the entire device, which leads to cumbersome installation and disassembly processes during maintenance or replacement, thereby effectively improving the convenience of the device. In addition, by setting up the cleaning device 6, when the smoke detector body 3 has been used for a long time, the exchange port 4 may be blocked by dust or foreign matter. The turntable 65 can be rotated left and right to make the rotating shaft 61 drive the rotating plate 62 to rotate, thereby making the cleaning block 63 rotate to clean the exchange port 4, and at the same time, the cleaning plate 64 rotates to clean the bottom of the inner wall of the smoke detector body 3, so that dust and foreign matter fall from the exchange port 4. By setting up the cleaning device 6, the exchange port 4 and the bottom of the inner wall can be cleaned without disassembling the smoke detector body 3, thereby avoiding dust and foreign matter blocking the exchange port 4 and causing equipment failure, thereby effectively improving the durability of the equipment.
