A retractable security smoke detector

Abstract

The invention discloses a scalable security smoke detector. An outer connector is sleeved and fixed in an upper-end hole provided with a step hole in the top surface of a room; the middle part of the top plate of the outer connector is provided with a wire through hole; the wire through hole and a connection hole at the top end of the step hole are aligned vertically; the inner side wall of the upper part of the outer connector is provided with an inner thread section; a driving motor connection plate is screwed in the inner thread section; the driving motor connection plate is in the outer connector; a driving motor is fixed on the top surface of the driving motor connection plate; the output shaft of the driving motor downwardly passes through the driving motor connection plate; the output shaft of the driving motor is hinged on the driving motor connection plate via a bearing; and an adjusting screw rod is screwed in an adjusting screw hole in the middle part of the bottom surface of the output shaft of the driving motor. The scalable security smoke detector can extend out automatically in the case of use for detection and block outer dust or oil smoke through a door body in the case of not use, and thus, the detection hole of a smoke sensor is not blocked easily, and the cleaning times are reduced.

Description

Technical field: [0001] The invention relates to the technical field of security equipment, in particular to a retractable security smoke detector. Background technique: [0002] Existing smoke sensors are installed bare on the top of the room of the house. When not in use, oil fume, dust, etc. will block the detection hole of the smoke sensor, thereby affecting the detection effect and need to be cleaned in real time. However, due to its general On the top surface (ie the ceiling) of the room, this makes its cleaning quite troublesome and increases labor intensity. Invention content: [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a retractable security smoke detector, which can automatically extend and detect when in use, and block external dust or oily smoke through the door when not in use, thereby making the smoke The detection hole of the sensor is not easy to block, which reduces cleaning times and improves...
