Description

Technical Field

[0001] This utility model relates to the field of smoke detector technology, and in particular to a magnetically mounted smoke detector. Background Technology

[0002] A smoke detector is a safety device used to detect smoke and signs of fire. It is typically installed in residential, commercial, and industrial locations to improve fire safety. Its main function is to detect smoke promptly and issue an alarm.

[0003] In existing technology, smoke detectors typically use batteries to maintain normal operation. Operators need to periodically check the detector's status and replace the batteries, requiring them to remove the detector from the wall. This is usually done by drilling holes in the wall and fixing the detector base to the wall with screws. Removing the detector requires turning the screws, which repeatedly rotates the screw holes, causing wear and tear on both the screws and the holes. This results in the screws not being able to fit tightly in the holes, leading to an unstable detector. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art where repeated rotation of the screw along the screw hole causes wear on the screw and the screw hole, and the screw cannot be tightly engaged in the screw hole, resulting in an unstable fixation of the smoke detector. Therefore, this invention proposes a magnetically mounted smoke detector.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a magnetically mounted smoke detector, comprising a smoke detector body and a fixing box, wherein a fixing component is provided inside the fixing box, the fixing component includes a first magnetic block, a second magnetic block is fixedly connected to the inner wall of the fixing box, a first fixing block is rotatably connected to the inner wall of the fixing box at its center, a third magnetic block is fixedly connected to one outer surface of the first fixing block, and a fourth magnetic block is fixedly connected to the other outer surface of the first fixing block.

[0006] Preferably, the first magnetic block is fixedly connected to the inner wall of the fixed box, and the outer surfaces of the third magnetic block and the fourth magnetic block are rotatably connected to the inner wall of the fixed box.

[0007] Preferably, a rotating shaft is fixedly connected to the outer surface of the first fixing block, and a fixing rod is fixedly connected to one end of the rotating shaft.

[0008] Preferably, a second fixing block is fixedly connected to the outer surface of the fixing box, and a spring is provided on the inner wall of the second fixing block.

[0009] Preferably, one end of the spring is fixedly connected to the inner wall of the second fixed block, and the other end of the spring is fixedly connected to a movable block.

[0010] Preferably, a plurality of evenly arranged first grooves are formed on one outer surface of the smoke detector body, a protective net is fixedly fitted on the outer surface of the smoke detector body, and a second groove is formed on the other outer surface of the smoke detector body.

[0011] Preferably, a third fixing block is provided on the inner wall of the second groove, a base plate is fixedly connected to one side of the outer surface of the fixing box, a plurality of evenly arranged nuts are threadedly connected to the inner wall of the base plate, and two stops are fixedly connected to the outer surface of the fixing box.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the device is equipped with a fixing component. The first and third magnetic blocks have the same magnetism, and the second and fourth magnetic blocks have the same magnetism. The four magnetic blocks will form a complete magnetic circuit. At the same time, the fixing box and the third fixing block are iron products.

[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Example 1: As Figures 1-9As shown, this utility model provides a magnetically mounted smoke detector, including a smoke detector body 1 and a fixing box 2. The fixing box 2 has a fixing component 3 inside, which includes a first magnetic block 301. A second magnetic block 302 is fixedly connected to the inner wall of the fixing box 2. A first fixing block 303 is rotatably connected to the inner wall of the fixing box 2 at its center. A third magnetic block 304 is fixedly connected to one outer surface of the first fixing block 303, and a fourth magnetic block 305 is fixedly connected to the other outer surface of the first fixing block 303. The first magnetic block 301 is fixedly connected to the inner wall of the fixing box 2, and the outer surfaces of the third magnetic block 304 and the fourth magnetic block 305 are... The surface of the first fixing block 303 is rotatably connected to the inner wall of the fixing box 2. A rotating shaft 4 is fixedly connected to the outer surface of the first fixing block 303. A fixing rod 5 is fixedly connected to one end of the rotating shaft 4. A second fixing block 6 is fixedly connected to the outer surface of the fixing box 2. A spring 7 is provided on the inner wall of the second fixing block 6. One end of the spring 7 is fixedly connected to the inner wall of the second fixing block 6. A moving block 8 is fixedly connected to the other end of the spring 7. A third fixing block 12 is provided on the inner wall of the second groove 11. A bottom plate 13 is fixedly connected to one side of the outer surface of the fixing box 2. A plurality of evenly arranged nuts 14 are threadedly connected to the inner wall of the bottom plate 13. Two stops 15 are fixedly connected to the outer surface of the fixing box 2.

[0028] The overall effect of Embodiment 1 is as follows: During the use of a magnetically installed smoke detector, the operator first needs to fix the base plate 13 to the wall. First, drill holes in the wall at the location where the smoke detector body 1 will be installed. Then, fix the fixing box 2 and the base plate 13 to the wall. The operator needs to first turn multiple nuts 14 into multiple screw holes until the outer surface of the nuts 14 is completely flush with the inner wall of the screw hole. Then, the operator attaches the bottom of the smoke detector body 1 to the outer surface of the fixing box 2. At this time, the outer surface of the third fixing block 12 is flush with the outer surface of the fixing box 2. Both the third fixing block 12 and the fixing box 2 are made of iron. At this time, the fourth magnetic block 305 is located on one side of the first magnetic block 301, and the third magnetic block 304 is located... On one side of the second magnetic block 302, the first magnetic block 301, the second magnetic block 302, the third magnetic block 304, and the fourth magnetic block 305 are all made of high-performance rare-earth permanent magnet material. This material can maintain permanent magnetism after magnetization and provides a strong magnetic field. This is a known technology and will not be explained in detail. The fourth magnetic block 305 has opposite magnetism to the first magnetic block 301, and their magnetism cancels each other out. The third magnetic block 304 has opposite magnetism to the second magnetic block 302, and their magnetism cancels each other out. Therefore, no magnetic attraction is generated at this time. At this time, the outer surface of the fixing rod 5 is in contact with the outer surface of one of the stops 15. Then, the operator rotates the fixing rod 5, which drives the rotating shaft 4 to rotate. The rotating shaft 4 drives the first fixing block 303 to rotate. Fixed block 303 will drive the third magnetic block 304 and the fourth magnetic block 305 to rotate. Then, when the outer surface of fixed rod 5 contacts movable block 8 after passing the rotating block, the operator needs to move movable block 8 and press it. Movable block 8 will compress spring 7, and the outer surface of movable block 8 will slide along the inner wall of the second fixed block 6 until the outer surface of fixed rod 5 no longer contacts movable block 8 when it continues to rotate, until the outer surface of fixed rod 5 contacts the outer surface of another stop block 15. At this point, the operator stops pressing movable block 8, and the elastic force of spring 7 will drive movable block 8 to move. At this time, fixed rod 5 is located between the outer surface of movable block 8 and one of the stop blocks 15, and at the same time, the third magnetic block 304 and the fourth magnetic block 305 are flipped. At this time, the third magnetic block 304 is located on one side of the first magnetic block 301, and the fourth magnetic block 305 is located on one side of the second magnetic block 302. The first magnetic block 301 and the third magnetic block 304 have the same magnetism, and the second magnetic block 302 and the fourth magnetic block 305 have the same magnetism. The first magnetic block 301, the second magnetic block 302, the third magnetic block 304 and the fourth magnetic block 305 will form a complete magnetic circuit, which will generate magnetic attraction through the outer surface of the fixing box 2, thereby firmly attracting the third fixing block 12 to the outer surface of the fixing box 2, thus firmly installing the smoke detector body 1 and the fixing box 2. This solves the problem that repeated rotation of the screw along the screw hole will cause wear on the screw and screw hole, and the screw cannot be tightly connected in the screw hole, resulting in the smoke detector not being firmly fixed.

[0029] Example 2: As Figures 1-9 As shown, a plurality of evenly arranged first grooves 9 are provided on one outer surface of the smoke detector body 1, a protective net 10 is fixedly fitted on the outer surface of the smoke detector body 1, and a second groove 11 is provided on the other outer surface of the smoke detector body 1.

[0030] The effect achieved by the entire embodiment 2 is that, during the use of a magnetically installed smoke detector, after the outer surface of the smoke detector body 1 is fixed to the outer surface of the fixing box 2, when the smoke detector body 1 is working normally, by setting a protective net 10 on the outer surface of the smoke detector body 1, small insects can be effectively prevented from entering the interior of the smoke detector body 1 from the interior of the first groove 9, thereby triggering the sensing device inside the smoke detector body 1. The small insects are intercepted on the outer surface of the protective net 10, thus ensuring the reliability of the smoke detector body 1.

[0031] Working Principle: In the operation of a magnetically mounted smoke detector, the operator first needs to fix the base plate 13 to the wall using nuts 14. Then, the bottom of the smoke detector body 1 is attached to the outer surface of the mounting box 2. The operator rotates the fixing rod 5, which drives the rotating shaft 4 to rotate. The rotating shaft 4 then drives the first fixing block 303 to rotate, which in turn drives the third magnetic block 304 and the fourth magnetic block 305 to rotate until the third magnetic block 304 is located to one side of the first magnetic block 301 and the fourth magnetic block 305 is located to one side of the second magnetic block 302. At this point, the first magnetic block 301, the second magnetic block 302, the third magnetic block 304, and the fourth magnetic block 305 will form a... A complete magnetic circuit generates magnetic attraction through the outer surface of the fixing box 2, thereby firmly attaching the third fixing block 12 to the outer surface of the fixing box 2. When the smoke detector body 1 is working normally, the protective net 10 on the outer surface of the smoke detector body 1 can effectively prevent small insects from entering the interior of the smoke detector body 1 from the interior of the first groove 9. This device, by setting the fixing component 3, generates a strong magnetic force on the surface of the fixing box 2 when the magnetic fields of the four magnetic blocks interact with the third fixing block 12 through the fixing box 2, thereby firmly attaching the third fixing block 12 to the outer surface of the fixing box 2, thus firmly fixing the smoke detector body 1.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
