DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0019] Embodiment 1:

[0020] Please refer to Figure 1-6, the present utility model provides a technical solution: a door-breaking device for fire fighting, including a door-breaking machine housing 100. A power slot 104 is provided inside the door-breaking machine housing 100. A fixed plate 108 is fixedly connected inside the power slot 104. A motor 109 is fixedly connected to the left end face of the fixed plate 108. A fixed sleeve 112 is fixedly connected to the right end face of the fixed plate 108. The fixed sleeve 112 is rotatably connected to a motor shaft 113. The motor 109 is power-connected to the motor shaft 113. The motor 109 can drive the motor shaft 113 to rotate. A sliding rod 116 is slidably connected to the left and right sides of the motor shaft 113. A rotating block 105 is fixedly connected to the right end face of the sliding rod 116. Three connecting plates 114 distributed in a circumferential array are fixedly connected to the side face of the motor shaft 113. The connecting plates 114 are fixedly connected to a hydraulic pump 117. The hydraulic pump 117 is power-connected to the rotating block 105. The hydraulic pump 117 can drive the rotating block 105 to move. A cutting blade 106 is fixedly connected to the right end face of the rotating block 105. By the high-speed rotation of the cutting blade 106, small holes can be drilled in the household door, so that hands can be stretched in, and then the door can be opened from the inside to extinguish the fire.

[0021] The rotating block 105 is provided with four through holes 115, and the circular block cut from the door can be pushed out through the rotating block 105;

[0022] The door-breaking machine housing 100 is fixedly connected with a side plate 110. A storage battery 111 located inside the power slot 104 is fixedly connected to the right end face of the side plate 110. The storage battery 111 supplies power to the motor 109;

[0023] A handle 101 is fixedly connected to the side face of the door-breaking machine housing 100. The handle 101 is provided with two control buttons 107. The operation of the motor 109 and the hydraulic pump 117 is controlled through the control buttons 107;

[0024] Four fixing rods 102 distributed in a circumferential array are fixedly connected to the side face of the door-breaking machine housing 100. Anti-slip plates 103 with their right end faces flush with the right end face of the door-breaking machine housing 100 are fixedly connected to the fixing rods 102. The anti-slip plates 103 prevent slipping when the rotating block 105 and the cutting blade 106 rotate at high speed.

[0025] Working principle:

[0026] When the firefighters cannot open the household door during fire fighting, by lifting the handle 101 with the hand, the door-breaking machine housing 100 and the anti-slip plate 103 are pressed against one side of the door lock, and the control button 107 is pressed to start the motor 109;

[0027] The motor 109 drives the motor shaft 113 to rotate, and the motor shaft 113 drives the sliding rod 116 and the rotating block 105 to rotate at high speed, and cooperates with the hydraulic pump 117 to push the rotating block 105 and the cutting blade 106 to move, so that the cutting blade 106 cuts the entrance door while rotating at high speed, drilling a small hole on one side of the door lock. After the firefighter reaches into the inside of the door, he can open the entrance door and put out the fire, avoiding accidents caused by hitting the door and being more efficient.

[0028] The battery 111 supplies power to the motor 109 , and the anti-slide plate 103 abuts against the entrance door to prevent the cutting blade 106 from sliding during operation.

[0029] It will be apparent to those skilled in the art that various modifications and variations may be made to the disclosed embodiments. Other embodiments will be readily apparent to those skilled in the art from consideration of the specification and practice of the disclosed system. It is intended that the specification and examples be considered exemplary only, with the true scope of protection being determined by the appended claims and their equivalents.
