Description

Technical Field

[0001] The utility model belongs to the technical field of electric welding equipment, and more specifically relates to a portable electric welding door-breaking device. Background Art

[0002] When criminals conduct illegal activities indoors (such as drug use, gambling, etc.), they will lock the room door in advance. When law enforcement officers conduct a surprise arrest, they need to break open the door first. Currently, the common method is to quickly destroy the door lock with a door-breaking hammer and a crowbar. However, the door locks of some anti-theft doors are very strong, making it difficult for the door-breaking hammer and the crowbar to remove the door lock in a short time. And the excessive door-breaking time will allow criminals to have time to destroy illegal tools (drugs, drug paraphernalia, gambling tools, etc.), resulting in insufficient evidence of the crime against criminals and affecting the sanction strength against criminals.

[0003] Therefore, the existing door-breaking methods and tools have low efficiency for law enforcement door-breaking. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a portable electric welding door-breaking device to improve the door-breaking efficiency of law enforcement officers.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A portable electric welding door-breaking device includes a backpack and an electric welding main body. The electric welding main body is located inside the backpack. A secondary bag is provided on the backpack, and an electric welding gun and electric welding rods are contained in the secondary bag. The electric welding gun can be connected to the internal electric welding main body from the side of the backpack, and the electric welding main body is detachably connected to the backpack.

[0006] Further, the electric welding main body includes a housing. A rechargeable battery, a circuit control board, a voltage regulator, and a leakage protector are provided inside the housing. A main power switch, an electric welding switch, a voltage display, and two connectors are provided on the housing. The main power switch, the electric welding switch, and the voltage display are all located on one side of the housing, and this side is the top surface of the housing when the electric welding main body is placed inside the backpack. The two connectors are located on both sides of the top surface. Through holes corresponding to the connectors are provided on both sides of the backpack for the connectors to extend out.

[0007] Further, a fixing ring is provided on the through hole, and a rubber ring is provided on the fixing ring.

[0008] Further, at least one first fixing strap and two second fixing straps are provided inside the backpack. The first fixing strap is arranged along the thickness direction of the backpack, and the second fixing straps are arranged along the width direction of the backpack. One end of the first fixing strap is fixedly connected to the inner wall of the backpack, and the other end is detachably connected to the inner wall of the backpack. One ends of the two second fixing straps are respectively fixedly connected to the inner wall of the backpack, and the other ends are telescopically connected to each other. The connection is connected to the electric welding gun.

[0009] Further, the other end of the first fixing band is connected to the inner wall of the backpack through a magic tape or a buckle, and the two second fixing bands can be connected through a magic tape or a buckle.

[0010] Further, a charging device for the welding main body is also installed in the secondary bag, a charging head is arranged on the top surface of the housing, and the charging head is connected to a rechargeable battery.

[0011] Further, a cooling fan is arranged on the side surface of the backpack.

[0012] Further, the whole body of the backpack is made of stab-proof fabric.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: Law enforcement officers can place the backpack with the welding main body behind them, and then hold the welding gun to quickly destroy the bolts used for fixing the door lock, so as to quickly open the door for law enforcement actions, which is faster than a crowbar and a battering ram, and improves the door-breaking efficiency.
