Technical Field

[0001] The utility model relates to the field of firefighting and rescue, in particular to a portable high-temperature resistant firefighting and rescue window breaking device. Background Art

[0002] In order to avoid untimely rescue in the event of a fire, many communities and fire brigades are equipped with high-temperature resistant fire rescue window-breaking devices to quickly break the windows for rescue.

[0003] Nowadays, many residential windows are equipped with protective windows. The cutting knife of the high-temperature fire rescue window breaking device will quickly cut the protective windows and then break the glass windows, making it easier for rescuers to enter the room for rescue.

[0004] However, when using today's high-temperature resistant fire rescue window breaking devices, some windows are on higher floors, and rescue workers are at high altitudes when cutting. The squeezing force between the cutting knife and the protective window is limited, resulting in a slower cutting speed. Utility Model Content

[0006] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a portable high-temperature resistant fire-fighting and rescue window-breaking device, comprising a main body, a mounting block fixed at the top of one side of the main body, and a slide groove arranged inside the mounting block, a slide column slidably connected inside the slide groove, a cutting bin fixed at the bottom of the slide column, and a first rack plate fixed on one side of the slide column, a first slot cooperating with the first rack plate arranged at the top of one side of the main body, and a second slot arranged at the bottom end of one side of the main body, a second rack plate slidably connected inside the second slot, a gear rotatably connected inside the main body, and a fixing frame fixed to the end of the second rack plate.

[0007] As a further solution of the utility model: the end of the fixing frame is rotatably connected to a rotating shaft, and a limiting rod is fixed to the end of the rotating shaft, and one end of the two groups of limiting rods is located on one side of the rotating shaft and a fixing rod is fixed thereto.

[0008] As a further solution of the utility model: the first rack plate and the gear are meshed with each other, and the second rack plate and the gear are meshed with each other.

[0009] As a further solution of the utility model: sliding grooves are arranged on both sides of the sliding groove, sliding blocks cooperating with the sliding grooves are arranged on both sides of the sliding column, and the sliding groove is connected to the first slot.

[0010] As a further solution of the utility model: a rotating motor is installed at the middle position of the bottom of the cutting chamber, and the output end of the rotating motor is fixedly connected to a cutting knife that penetrates into the interior of the cutting chamber.

[0011] As a further solution of the utility model: a handle is fixed on one side of the top of the main body, and a lithium battery pack is installed on one side inside the main body.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. By squeezing the fixed frame, the limit rod rotates inward. At this time, a steel bar of the protective window enters the interior of the fixed frame. At this time, the sliding rod is pushed, and the sliding rod drives the cutting chamber close to the steel bar. At the same time, under the action of the mutual engagement of the gear, the first rack plate and the second rack plate, the first rack plate and the second rack plate move relative to each other, and the second rack plate drives the fixed frame to move inward, thereby making the contact force between the cutting knife and the steel bar greater, avoiding the cutting knife itself from shaking when the rescue personnel are at a high place, affecting the rescue safety, and at the same time increasing the cutting speed and increasing the rescue time.
