Description

Technical Field

[0001] The utility model relates to a mounting component of a fire detector, in particular to an anti-lost base of the fire detector. Background Art

[0002] Detectors are a crucial component of automatic fire alarm systems, used to monitor the environment for fires and issue timely alerts. As core components, detectors are typically attached to the lower end of a base using a swivel mount. The base is then directly connected to a pre-set panel on the wall. If a detector is lost, the base attached to it will not provide an alarm, making it easy to lose. Utility Model Content

[0003] In order to solve the above technical problems, the purpose of the present utility model is to provide a fire detector anti-loss base, by arranging a pair of upper elastic contact pieces and lower elastic contact pieces spaced apart from each other on the base body. When the detector is on the base body, the detector squeezes the upper elastic contact piece and the lower elastic contact piece to form a passage. When the detector is removed, the upper elastic contact piece and the lower elastic contact piece can be reset and separated to trigger an alarm.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A fire detector anti-loss base includes a base body connected to the detector, wherein a first terminal and a second terminal are provided on the base body, the first terminal and the second terminal are arranged relative to each other, an upper elastic contact piece extending above the second terminal is provided on the first terminal, and a lower elastic contact piece extending above the first terminal is provided on the second terminal, the extended end portion of the upper elastic contact piece and the extended end portion of the lower elastic contact piece are relative to each other with upper and lower intervals, the extended end portion of the upper elastic contact piece is squeezed by the detector and contacts the extended end portion of the lower elastic contact piece to form a passage, and when the detector is removed, the extended end portion of the upper elastic contact piece and the extended end portion of the lower elastic contact piece are reset and separated to form a short circuit.

[0006] Furthermore, the extended end portion of the lower elastic contact piece has a lower bending portion bent downward, and the extended end portion of the upper elastic contact piece has an upper bending portion extending downward, and the upper bending portion and the lower bending portion contact to form a passage.

[0007] Furthermore, the first terminal includes a first metal sheet, and the opposite ends of the first metal sheet are provided with a first flange sheet inserted into the base body. The upper elastic contact sheet is a V-shaped structure, and the lower end of the upper elastic contact sheet is connected to the side of the first metal sheet, and the vertical projection of the upper elastic contact sheet is parallel to the first metal sheet.

[0008] Furthermore, the second terminal includes a second metal sheet, and the opposite ends of the second metal sheet are provided with second flange sheets inserted into the base body, and the side of the second metal sheet is provided with a third flange sheet inserted into the base body. The lower elastic contact sheet is a straight-line structure, and the lower end of the lower elastic contact sheet is connected to the side of the second metal sheet, and the vertical projection of the lower elastic contact sheet is perpendicular to the second metal sheet.

[0009] Furthermore, a first screw hole is provided on the first metal sheet, and a connecting screw is connected to the first screw hole.

[0010] Furthermore, a second screw hole is provided on the second metal sheet, and a connecting screw is connected to the second screw hole.

[0011] Furthermore, a slot is provided on the base body, the lower portion of the upper elastic contact piece is embedded in the slot, and the upper portion of the upper elastic contact piece extends out of the slot.

[0012] Furthermore, the upper elastic contact piece and the lower elastic contact piece are elastic metal sheets.

[0013] Due to the adoption of the above technical solution, the utility model has the following advantages and effects:

[0014] The utility model provides a fire detector anti-loss base, which is equipped with a pair of upper elastic contact pieces and lower elastic contact pieces with upper and lower ends spaced apart on the base body. When the detector is snapped onto the base body, the detector squeezes the upper elastic contact piece and the lower elastic contact piece into contact to form a pathway to ensure normal connection. When the detector is removed, the upper elastic contact piece and the lower elastic contact piece separate to form a circuit break, thereby generating an alarm and avoiding the problem of no alarm after the detector is removed.
