The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and enable those of ordinary skill in the art to understand the present invention and thus design various embodiments with various modifications suitable for specific purposes.

[0018] Embodiment: Please refer to Figure 1 - Figure 4 , the present invention provides a technical solution: a detachable combined electrical fire detector, including: a fixed plate 1; a connecting device 2, the outer wall of the connecting device 2 is fixedly connected to the outer wall of the fixed plate 1; a detector body 3, the outer wall of the detector body 3 is slidably connected to the outer wall of the connecting device 2; the connecting device 2 includes a connection box 21, ventilation holes 22 are opened at both ends of the connection box 21, a fixing device 23 is fixedly connected to the inner wall of the connection box 21, a partition board 24 is slidably connected to the outer wall of the fixing device 23 through a chute 25, and the chute 25 is opened on the outer wall of the partition board 24, and the outer wall of the partition board 24 is fixedly connected to the inner wall of the connection box 21.

[0019] The fixing device 23 includes a double-headed reduction motor 231, the output end of the double-headed reduction motor 231 is fixedly connected to a driving screw 232, an adjusting block 233 is threadedly connected to the outer wall of the driving screw 232, a positioning rod 234 is slidably connected to the inner wall of the adjusting block 233, a connecting shaft 235 is fixedly connected to the outer wall of the adjusting block 233, a connecting rod 236 is rotatably connected to the outer wall of the connecting shaft 235, a sliding column 237 is rotatably connected to the end of the connecting rod 236 away from the connecting shaft 235, a limiting shell 238 is slidably connected to the outer wall of the sliding column 237, a positioning cylinder 239 is arranged outside the limiting shell 238, the outer wall of the limiting shell 238 is fixedly connected to the outer wall of the connection box 21, both ends of the positioning rod 234 are fixedly connected to the outer wall of the connection box 21, the outer wall of the double-headed reduction motor 231 is fixedly connected to the outer wall of the fixed plate 1, the outer wall of the positioning cylinder 239 is fixedly connected to the inner wall of the connection box 21, and the inner wall of the positioning cylinder 239 is rotatably connected to the outer wall of the driving screw 232.

[0020] The detector body 3 includes a detector housing 31. An extension block 32 is fixedly connected to the outer wall of the detector housing 31. A connection hole 33 is formed in the wall of the extension block 32. The outer wall of the extension block 32 is slidably connected to the outer wall of the sliding column 237 through the connection hole 33. The outer wall of the detector housing 31 is slidably connected to the outer wall of the connection box 21. The ventilation holes 22 at both ends of the connection box 21 in the connection device 2 play a role in ventilation and heat dissipation. The detector body 3 is placed into the connection box 21 until one end of the detector housing 31 close to the extension block 32 fits against the partition board 24. At this time, the extension block 32 extends into the inner area of the connection box 21 from the upper and lower ends of the partition board 24. Start the double-headed reduction motor 231 in the fixing device 23 to drive the driving screw 232 to rotate. Since the rotation directions of the double-headed reduction motors 231 are the same, the thread rotation directions of the driving screws 232 on both sides are opposite. Thus, while the adjusting blocks 233 slide on the positioning rods 234, they can approach or move away from each other. While the positioning cylinder 239 enables the driving screw 232 to rotate stably, the adjusting block 233 drives the sliding column 237 to slide in the groove of the limit housing 238 through the connecting shaft 235 and the connecting rod 236. And the connecting shaft 235 stably moves on the sliding groove 25 under the drive of the adjusting block 233. When controlling the adjusting blocks 233 to move away from each other, the connecting rod 236 can be pushed through the connecting shaft 235. When it is necessary to install the detector body 3, the sliding column 237 is inserted into the connection hole 33 of the extension block 32 to realize the fixed connection between the detector body 3 and the connection device 2.

[0021] Working principle:

[0022] In use, in this easily detachable combined electrical fire detector, the fixing plate 1 is used for the overall fixation and support. The ventilation holes 22 at both ends of the connection box 21 in the connection device 2 play a role in ventilation and heat dissipation. The detector body 3 is placed into the connection box 21 until one end of the detector housing 31 close to the extension block 32 fits against the partition plate 24. At this time, the extension block 32 extends into the internal area of the connection box 21 from the upper and lower ends of the partition plate 24. Start the double-headed reduction motor 231 in the fixing device 23 to drive the driving screw 232 to rotate. Since the rotation directions of the double-headed reduction motor 231 are the same, the thread rotation directions of the driving screws 232 on both sides are opposite. As a result, while the adjusting blocks 233 slide on the positioning rods 234, they can approach or move away from each other. While the positioning cylinder 239 enables the driving screw 232 to rotate stably, the adjusting block 233 drives the sliding column 237 to slide in the groove of the limit housing 238 through the connecting shaft 235 and the connecting rod 236. And the connecting shaft 235 moves stably on the sliding groove 25 under the drive of the adjusting block 233. When controlling the adjusting blocks 233 to move away from each other, the connecting rod 236 can be pushed through the connecting shaft 235. When the detector body 3 needs to be installed, the sliding column 237 is inserted into the connection hole 33 of the extension block 32 to realize the fixed connection between the detector body 3 and the connection device 2. The partition plate 24 plays a role in blocking and protection. During disassembly, the double-headed reduction motor 231 rotates in the reverse direction to make the sliding column 237 disengage from the connection hole 33, and then the detector body 3 can be removed from the connection device 2.

[0023] By separating the connection mechanism of the combined electrical fire detector and the detector body 3 through a partition plate, it can effectively protect the detector body 3 from possible interference and collision generated during the operation of the connection mechanism, ensure that the precise detection function of the detector body 3 is not affected, improve the accuracy and stability of detection. The separation design helps to isolate the heat and possible electromagnetic interference generated by the connection mechanism, reduce the damage to the electronic components of the detector body 3, and extend the service life of the detector. Moreover, separating the two can more clearly distinguish the functions and maintenance requirements of different parts, facilitate maintenance personnel to carry out targeted repairs and maintenance, reduce the time and difficulty of troubleshooting. At the same time, the separated area can, to a certain extent, enhance the overall structural strength of the detector, improve its anti-impact and anti-seismic performance, make it work more reliably in a complex environment, prevent dust and impurities inside the detector body 3 from entering the connection mechanism, and keep the connection smooth and stable.

[0024] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art without special description and limitation.
