Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishers, and more specifically, to a vehicle-mounted fire extinguisher. Background Art

[0002] A fire extinguisher is a portable fire-fighting tool. Chemicals are placed in the fire extinguisher to put out fires. Fire extinguishers are one of the common firefighting equipment and are stored in public places or places where fires may occur. Different types of fire extinguishers are filled with different ingredients and are designed for different causes of fire. Car fire extinguishers are specially used for car fire extinguishing.

[0003] After searching, the utility model patent with announcement number CN219539303U discloses a vehicle-mounted fire extinguisher, including a tank body and a handle and a nozzle arranged at one end of the tank body; the vehicle-mounted fire extinguisher also includes a plurality of brackets for fixing the tank body, the tank body is placed on the brackets, and a window breaker is also provided on the brackets. In addition, when an accident occurs, the vehicle windows can also be broken by the window breaker; after the vehicle-mounted fire extinguisher of this structure is placed on the vehicle, it contacts the vehicle body through a plurality of brackets and will not roll back and forth in the vehicle. In addition, when an accident occurs, the vehicle windows can also be broken by the window breaker; compared with the fire extinguisher of the existing structure, it has the advantages of more complete functions, higher safety, and more convenient and easy fixing and carrying.

[0004] However, the above patent still has the following shortcomings: although the bracket can support the fire extinguisher tank, the vehicle will be subjected to centrifugal force when the vehicle turns. When the centrifugal force is too large, the fire extinguisher will slip, which will also affect the placement stability of the fire extinguisher. For this reason, we propose a vehicle-mounted fire extinguisher. Utility Model Content

[0014] (1) In the utility model, a supporting square seat is used to support the fire extinguisher bottle body so that the fire extinguisher bottle body can be placed on the hard bottom surface of the trunk. The pulling block is pulled to drive the pulling seat to rotate, so that the bottom surface of the operating groove changes from contacting with the arc surface to contacting with the supporting surface. When the pulling seat rotates, the pulling column is pulled, and the pulling column is used to drive the piston plate to move upward, so that the bottom of the adsorption groove cavity generates negative pressure to absorb the hard surface, thereby achieving stable placement of the fire extinguisher bottle body and the window breaking mechanism, and preventing the fire extinguisher bottle body from slipping.
