Abstract
Claims
1. A device for breaking doors and windows for fire fighting and rescue, comprising two sets of cross-hinged grips (1), characterized in that: An arc-shaped cutting piece (2) is fixedly extended from the front end of the handle (1). The cutting piece (2) is connected to the handle (1) by a bend. A set of the handles (1) is also provided with a fixing ring (3) with anti-slip texture on its surface. A cover (4) extends from one side of the fixing ring (3). A retractable breaker hammer (5) is telescopically installed inside the cover (4). The breaker hammer (5) breaks the stress of the door and window by telescopically extending and resetting.
2. The device according to claim 1, characterized in that: The breaker (5) includes a sliding shaft (51) that slides on one side of the cover (4). A breaker rod (52) extends from the middle of the sliding shaft (51) along the central axis of the cover (4) toward the other side of the cover (4) and extends out of the cover (4). The end of the breaker rod (52) is a cone. A limiting plate (521) is provided on the circumferential surface of the breaker rod (52). The limiting plate (521) is slidably connected to the other side of the cover (4).
3. The device according to claim 2, characterized in that: The cover (4) has a positioning plate (41) in the middle. The sliding shaft (51) is located on one side of the positioning plate (41) and the crushing rod (52) slides on the positioning plate (41). A reset spring (53) is provided between the positioning plate (41) and the limiting plate (521). The reset spring (53) covers the crushing rod (52).
4. The device according to claim 2, characterized in that: The top of the cutting component (2) is provided with a spike (21), which is conical and symmetrically arranged in two sets. The spike (21) is used to break doors and windows, and the spike (21) is opposite in direction to the end of the breaking rod (52).
5. The device according to claim 3 or 4, characterized in that: The inner wall of the cover (4) is provided with slider one (42) and slider two (43), and slider one (42) and slider two (43) are separated by positioning plate (41). Positioning plate (41) is slidably connected to slider two (43), and sliding shaft (51) is slidably adapted to slider one (42).
6. The device according to any of claims 2-4, characterized in that: A pull ring (511) is also fixedly extended from the other side of the sliding shaft (51).
7. The device according to claim 1, characterized in that: The inner wall of the cutting component (2) is also provided with an arc-shaped blade (22) and there are two sets of them. The two sets of blades (22) cut the steel bars when they are brought close by the handle (1).
