Composite alarm for indoor gas leakage and CO induction detection

Abstract

The utility model discloses a composite alarm for indoor gas leakage and CO induction detection, which relates to the technical field of composite alarms and comprises a bottom plate placing plate, a protective shell, an upper fixing structure, a dustproof structure and a side fixing structure. A composite alarm is placed at a protruding position on a bottom plate placing plate, then a protective shell is taken to be matched with a connecting groove, then a U-shaped connecting rod is rotated, the rotation of the U-shaped connecting rod drives a first telescopic rod to rotate, the rotation of the first telescopic rod drives a fixed circular plate to rotate, and the fixed circular plate is fixed. When the lower end of a fixed circular plate directly faces the upper end of a protective shell, a sliding block slides, sliding of the sliding block drives a U-shaped connecting rod to slide, then the fixed circular plate is driven to slide, and finally a first telescopic rod stretches out and draws back, so that the lower end of the fixed circular plate is tightly attached to the upper end of the protective shell, and through the operation, the protective shell is fixed to a bottom plate containing plate easily; therefore, the composite alarm is fixed on the bottom plate placing plate and is prevented from falling off during installation.

[0002] A composite alarm is a safety device that integrates multiple alarm functions, usually including sound and light alarms, vibration alarms, smoke alarms and other functions, which can help people promptly detect and deal with various safety risks. However, when the composite alarm is exposed to the outside for a long time, it is easy to be contaminated with dust and oil smoke, which affects the effect of the detection alarm. In addition, if the composite alarm is not fixed sufficiently during installation, it may easily fall off. Therefore, technicians in this field provide a composite alarm for indoor gas leaks and CO sensing detection to solve the problems raised in the above background technology. Utility Model Content

[0008] Place the composite alarm at the protruding position on the bottom plate placement plate, then take the protective shell to make it fit into the connecting groove, and then rotate the U-shaped connecting rod. The rotation of the U-shaped connecting rod drives the rotation of the first telescopic rod, and then drives the rotation of the fixed circular plate. When the lower end of the fixed circular plate is facing the upper end of the protective shell, slide the slider. The sliding of the slider drives the sliding of the U-shaped connecting rod, and then drives the sliding of the fixed circular plate. Finally, extend and retract the first telescopic rod to make the lower end of the fixed circular plate close to the upper end of the protective shell. This operation is conducive to fixing the protective shell on the bottom plate placement plate, thereby fixing the composite alarm on the bottom plate placement plate.

[0009] Rotate the circular shaft, and the rotation of the circular shaft drives the rotation of the second telescopic rod, which in turn drives the rotation of the fixed connecting plate and the fixed soft plate, and then extend and retract the second telescopic rod, and the extension and retraction of the second telescopic rod drives the extension and retraction of the fixed connecting plate and the fixed soft plate. This operation is beneficial to further strengthen the fixing effect of the protective shell and the composite alarm on the basis of the fixation of the upper fixed structure.

[0010] When the device has been used for too long and dust and oil smoke affect the detection alarm, pull the pull plate. The pulling of the pull plate drives the separation of the buckle and the buckle groove, thereby driving the pulling of the air plate. The pulling of the air plate drives the pulling of the connecting rod, thereby driving the pulling of the filter plate. This operation is conducive to removing dust and oil smoke without dismantling the entire device, thereby ensuring its working efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
