[0018] The following will be combined with the Figure 1-Figure 5The present invention is described in detail, and the technical solutions in the embodiments of the present invention are clearly explained. Although the embodiments described are complete, it is obvious that the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] It should be noted that when a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a central component. When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may also be a central component. When a component is considered to be "set on" another component, it may be directly set on the other component or there may also be a central component. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] See also Figures 1 to 5 The utility model is an Internet of Things alarm device, including a smoke alarm body 1, which is detachably connected to a top cover 2. The left and right ends of the top cover 2 are fixedly connected with connecting ears 3. When installing the Internet of Things alarm device, the top cover 2 is pre-fixed on an external wall through the connecting ears 3 on the left and right ends. The smoke alarm body 1 can detect the surrounding smoke. When smoke is detected, it automatically goes online to alarm, reminding the user that there is a possibility of fire danger, so that the user can deal with it in time or escape from the scene.

[0022] It is worth noting that the technical features such as the smoke alarm body 1 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control method and spatial layout method of these technical features can be selected according to conventional methods in the field, and this technical solution will not be further elaborated.

[0023] Specifically, the inner wall of the top cover 2 is embedded with multiple groups of cavities 21, and the inner wall of the cavity 21 is provided with a rubber layer; the top of the smoke alarm body 1 is recessed inward to form a groove 4, and a disc 8 is slidably connected in the groove 4. A handle 5 is rotatably connected to the inner wall of the smoke alarm body 1, and the other end of the handle 5 is fixedly connected to the worm in the worm gear 6, and the worm gear 6 is rotatably connected to the groove 4. The worm in the worm gear 6 is fixedly connected to the bottom of the screw 7, and the side of the screw 7 is threadedly connected to the inner thread of the threaded sleeve 71, and the top of the threaded sleeve 71 is connected to the disc 8. The bottom is fixedly connected, the left and right ends of the groove 4 are respectively fixedly connected to the bottom of the telescopic rod, and the movable end of the top of the telescopic rod is fixedly connected to the disc 8. The side wall of the disc 8 forms a slope 9 of a <-shaped structure. The disc 8 is symmetrically fixed together by two sets of frustums so that the side wall of the disc 8 has a curvature to facilitate the squeezing of the squeezing rod 11. The inner wall of the smoke alarm body 1 is fixedly connected to one end of the spring 10, and the other end of the spring 10 is fixedly connected to the squeezing rod 11. The squeezing rod 11 passes through the spring 10 and is slidably connected to the inner side wall of the upper end of the smoke alarm body 1.

[0024] Specifically, the size of the cavity 21 matches that of the extrusion rod 11 , and the number of the extrusion rod 11 and the number of the cavity 21 are the same, and the diameter of the disk 8 matches that of the groove 4 .

[0025] Specifically, when the smoke alarm body 1 needs to be installed, the upper area of ​​the smoke alarm body 1 is inserted into the top cover 2, and then the handle 5 is twisted to drive the worm gear 6 to rotate. The worm gear 6 drives the screw 7 to rotate and push the threaded sleeve 71 and the disc 8 to move upward, so that the outermost edge of the slope 9 on the disc 8 simultaneously applies force to push the extrusion rods 11 outward. The extrusion rods 11 and the tension spring 10 move outward, so that multiple groups of extrusion rods 11 are simultaneously inserted into the cavity 21 in the top cover 2, thereby increasing the contact area and friction between the smoke alarm body 1 and the top cover 2, achieving a stable installation, and completing the fixation of the smoke alarm body 1 and the top cover 2;

[0026] When the smoke alarm body 1 and the top cover 2 are disassembled, the handle 5 is twisted in the opposite direction to move the disc 8 downward. After the squeezing effect of the slope 9 on the disc 8 on the squeezing rod 11 disappears, the spring 10 drives the squeezing rod 11 inward, and the squeezing rod 11 is disconnected from the cavity 21, thereby simplifying the disassembly process and allowing the smoke alarm body 1 to be easily removed from the top cover 2.

[0027] The above shows and describes the basic principles, main features and advantages of the present invention, and the standard parts used in the present invention can be purchased from the market, and special-shaped parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0028] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
