[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Figures 1-3 As shown, this portable oxy-acetylene welding and cutting device mainly consists of a tank housing 1, an oxygen cylinder 2, an acetylene cylinder 3, a pressure-resistant hose, and a cutting torch 5.

[0026] Figure 1 and Figure 2 As shown, the tank storage box 1 is the main supporting structure of the entire device. It is equipped with oxygen cylinder storage slots 11 and acetylene cylinder storage slots 12, which are spaced apart to prevent collisions between oxygen cylinders 2 and acetylene cylinders 3, ensuring safe operation. A handle 13 is installed at the top of the tank storage box 1 for easy carrying. A shoulder strap 14 is provided on the rear side of the tank storage box 1, allowing firefighters to choose between carrying by hand or on their back, improving portability.

[0027] Oxygen cylinder 2 is placed in oxygen cylinder placement slot 11, and acetylene cylinder 3 is placed in acetylene cylinder placement slot 12. The slots are used to position and fix oxygen cylinder 2 and acetylene cylinder 3 to prevent them from shaking during transport.

[0028] The pressure-resistant hose is used to connect the oxygen cylinder 2 and the acetylene cylinder 3, and to deliver the gas to the cutting torch 5. A pressure-resistant hose storage assembly 6 is provided on the front side of the tank storage box 1. This assembly includes a winding boss 61 and baffles 62. The winding boss 61 is located on the front side of the tank storage box 1, and the baffles 62 are located on the front side of the winding boss 61, extending radially outwards from the winding boss 61, and are spaced apart along the circumference of the winding boss 61. After use, the pressure-resistant hose is wound around the winding boss 61, and the baffles 62 act as retainers to prevent the hose from scattering, facilitating storage and future use.

[0029] The winding boss 61 is provided with a tool placement slot 63, which contains multiple tool fixing slots 631. These slots are used to hold tools related to oxy-acetylene welding and cutting, such as wrenches and screwdrivers, and to secure the tools in place, preventing them from shaking or colliding during transport. A cover plate is provided on the tool placement slot 63 to prevent tools from falling out and to protect them from external environmental influences.

[0030] Figure 2 and Figure 3 As shown, torch fixing components 7 are provided on the left and right sides of the tank storage box 1 for fixing the torch 5. The torch fixing component 7 includes a first fixing block 71 and a second fixing block 72, which are arranged vertically at intervals. The first fixing block 71 is provided with a first snap-fit ​​groove 711 for snapping the pipe part of the torch 5, and the second fixing block 72 is provided with a second snap-fit ​​groove 721 for snapping the handle part of the torch 5. This snap-fit ​​method can securely fix the torch 5 to the tank storage box 1 for easy carrying.

[0031] Working principle:

[0032] When in use, firefighters choose to carry the portable oxy-acetylene welding and cutting device to the work site by hand (handle 13) or on their back (sling 14), depending on the actual situation. Upon arrival, remove the torch 5 from the torch holder 7, remove the pressure hose from the retractor 61, and open the cover of the tool storage slot 63 to retrieve the necessary tools. Remove the oxygen cylinder 2 and acetylene cylinder 3 from the oxygen cylinder storage slot 11 and acetylene cylinder storage slot 12 respectively. Use tools to open the valves of the oxygen cylinder 2 and acetylene cylinder 3, connect the pressure hose to the oxygen cylinder 2 and acetylene cylinder 3, and then connect the torch 5 to the pressure hose. Open the valves of the oxygen cylinder 2 and acetylene cylinder 3 to allow the oxygen and acetylene gases to mix and be delivered to the torch 5 through the pressure hose. The mixture burns at the torch 5, generating a high-temperature flame for metal cutting. After the operation is completed, return all components to their original positions in reverse order for future use.

[0033] Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model are within the protection scope of this utility model.
