Description

Technical Field

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

[0002] Smoke detectors, also known as smoke sensors, prevent fires by monitoring the concentration of smoke. Smoke detectors use ion smoke sensors inside. Ion smoke sensors are technologically advanced, stable and reliable sensors that are widely used in various fire alarm systems. Their performance is far superior to gas-sensitive resistor fire alarms. Wireless smoke detectors need to be easy to install when in use.

[0003] The Chinese utility model patent with application number 202223372514.9 discloses a wireless smoke detector that is easy to install. The above technical solution sets a rotating knob, a threaded column, a fixing ring and a connecting ring to be connected with the base, and sets a fixing shaft and a fixing plate. When the end of the fixing shaft away from the fixing plate passes through the rotating knob, the threaded column, the fixing ring and the connecting ring and extends to the top surface of the fixing seat, and when one side of the limit ring fits with the top surface of the rotating knob, it means that the fixing shaft has moved to the appropriate position. The worker can put his hand between the rotating knob and the fixing plate and start to rotate the rotating knob. When the rotating knob is rotated, the limit block in the threaded column is tightened inward to fix the extending fixing shaft. This fixing method does not require additional tools to assist during installation, which is conducive to saving installation time.

[0004] However, in actual use, the above technical solution needs to continuously rotate the rotary knob during use, thereby increasing the installation process, and the installation method is relatively cumbersome and inconvenient.

[0005] Therefore, a wireless smoke detector which is easy to install is proposed. Utility Model Content

When the wireless smoke detector body 1 is installed, the fixed trapezoidal block 502 and the movable trapezoidal block 503 can be directly inserted into the interior of the installation sleeve 3, and then the fixed trapezoidal block 502 can push the plug-in trapezoidal blocks 404 on both sides inward into the interior of the installation groove 302. Then, when the fixed trapezoidal block 502 moves to be staggered with the plug-in trapezoidal block 404, under the action of the spring 403, the plug-in trapezoidal block 404 can return to its original position, and at this time, the plug-in trapezoidal block 404 can be fixed The trapezoidal block The bottom of 502 acts as a barrier. When the wireless smoke detector body 1 is loosened, under the action of gravity, the fixed trapezoidal block 502 can be clamped on the top of the two plug-in trapezoidal blocks 404, so that the wireless smoke detector body 1 can be installed. When it needs to be disassembled, the wireless smoke detector body 1 is pushed upward continuously, and the movable trapezoidal block 503 can squeeze the plug-in trapezoidal blocks 404 on both sides into the inside of the installation groove 302. After that, the movable trapezoidal block 503 is staggered from the plug-in trapezoidal block 404, and under the action of the spring 403, the plug-in trapezoidal block 4 04 can be restored to its original position, and finally the connecting plate 601 can contact with the bottom surface of the installation sleeve 3, and then the wireless smoke detector body 1 is pulled downward. At this time, under the action of the plug-in trapezoidal block 404, the movable trapezoidal block 503 can slide upward, so that its top surface contacts with the bottom surface of the fixed trapezoidal block 502. In the process of its downward movement, the movable trapezoidal block 503 will squeeze the plug-in trapezoidal block 404, so that the fixed trapezoidal block 502 can be taken out from the inside of the plug-in slot 301, thereby completing the disassembly of the wireless smoke detector body 1.

[0027] like Figure 2 As shown, a plug-in slot 301 is formed at the bottom end of the installation sleeve 3 , and two installation slots 302 are respectively arranged on both sides of the plug-in slot 301 .
