Description

Technical Field

[0001] This utility model relates to the field of fire rescue technology, and in particular to a fire rescue demolition tool. Background Technology

[0002] In modern firefighting, breaching is an important rescue method. Traditional breaching mainly involves breaking down doors. The main method of breaking down doors is by force, and the main tools are axes and crowbars. Axes require a lot of force to break down doors, while crowbars mainly use the lever principle, so they have the advantages of saving effort and improving operational precision.

[0003] Although firefighters wear gloves during the demolition process, the surface of the crowbar is relatively smooth, and the crowbar needs to be pulled with great force when in use. Therefore, when firefighters use the crowbar, their hands can easily separate from the crowbar. When prying open a door, the distance between the hands and the point of force is also very important. The appropriate point of force can make the force evenly distributed, thereby preventing the crowbar from bending during the demolition process, and also saving effort and improving demolition efficiency.

[0004] In response to the above situation, we propose a fire rescue demolition tool. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fire rescue demolition tool.

Next, the user rotates the limiting screw 17 to move the limiting tooth block 16, separating it from the gear 15, allowing the rotating rod 14 to rotate. The user then holds the handle 19 and rotates it, causing the rotating rod 14 to rotate, winding the connecting rope 20 around its surface, thus allowing the connecting rope 20 to be stored. When the bottom of the protective sleeve 21 rests against the outer surface of the positioning frame 22, the user rotates the movable screw 24... The screw 24 drives the movable plate 23 to move, and the movable plate 23 clamps the connecting rope 20 with the positioning frame 22. Finally, the user rotates the limiting screw 17 to drive the limiting tooth block 16 to move. The limiting tooth block 16 meshes with the gear 15, so that the position of the rotating rod 14 is fixed, thereby achieving the purpose of limiting the position of the protective sleeve 21. Then, the user rotates the fixing screw 11 to drive the fixing tooth block 10 to move, so that the fixing tooth block 10 separates from the tooth plate 6, allowing the movable sleeve 7 to move. Then, the user moves the position of the movable sleeve 7 so that the movable sleeve 7 is located at a suitable force point. Then, the user rotates the fixing screw 11 to drive the fixing tooth block 10, so that the fixing tooth block 10 meshes with the tooth plate 6, thereby achieving the purpose of fixing the position of the movable sleeve 7.

[0025] During the demolition, the user holds the outer surface of the movable sleeve 7 with both hands, selects the appropriate demolition structure according to the actual demolition situation, inserts the tip of the demolition mechanism into the gap of the demolition object, and at the same time spreads the feet apart and uses force to open the gap to achieve the purpose of demolition.

[0026] When storing, the user rotates the fixing screw 11 to move the fixing tooth block 10, so that the moving sleeve 7 can move on the surface of the fixed pry bar 1. Then, the moving sleeve 7 is moved so that the top of the moving ring 12 fits against the bottom of the flat pry bar 3. Then, the user rotates the movable screw 24 and the limiting screw 17 so that the user can pull the connecting rope 20 and put the protective sleeve 21 on the outer surface of the pointed pry bar 4. Then, the user holds the handle 19 and rotates it so that the connecting rope 20 is in a taut state. Then, the user rotates the movable screw 24 and the limiting screw 17 to fix the position of the connecting rope 20, thereby further protecting the tip of the pointed pry bar 4.
