[0003] The aforementioned comparative documents and existing technologies have the following technical problems: Existing respirator wearable devices are mostly used for emergency treatment of breathing difficulties or in the event of a fire. However, due to the urgency, they often result in poor fixation and low wearing efficiency when wearing the respirator because they are not properly secured. Furthermore, they are only suitable for the assembly and use of respirators and cannot provide other services in emergency situations. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rapid wearing and fixing device for respirators.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a respirator quick-wearing and fixing device, including a back support, a placement frame on the back of the back support, an air cylinder inside the placement frame, a mask placement area on the top of the back support, storage boxes on both sides of the placement frame, a snap-fit ​​strap on one side of the back support, a connecting strap on the other side of the back support, a detector on the front of the back support, and a stabilizing rod at the bottom of the back support.

[0006] Preferably, the back support is made of hard plastic, and the front of the back support is provided with a skin-friendly cotton pad. The back support and the placement rack are connected by screws.

[0007] Preferably, one side of the placement rack is provided with an adjustment block, the adjustment block has an adjustment groove inside, and the adjustment groove has a retaining strip inside.

[0008] Preferably, the mask placement area includes a groove, with sliding clamps on both sides of the groove, and a slider at the bottom of each sliding clamp. The slider is the same size as the groove, and the top of each sliding clamp is arc-shaped.

[0009] Preferably, the back support and the storage box are connected by welding, and the storage box has a drawer inside.

[0010] Preferably, the snap-fit ​​strap includes a first telescopic opening, the port of the first telescopic opening is provided with a first elastic strap, the other side of the first elastic strap is provided with a limiting block, the other side of the limiting block is provided with a snap-fit ​​connector, and the snap-fit ​​connector is made of a magnet.

[0011] Preferably, the connecting strap includes a second telescopic opening, the port of the second telescopic opening is provided with a second elastic strap, the other side of the second elastic strap is provided with a snap-fit ​​block, the snap-fit ​​block is provided with a snap-fit ​​groove inside, and the snap-fit ​​groove is provided with a magnetic suction module inside.

[0012] Preferably, the stabilizing rod includes a fixed base, the bottom of the fixed base is provided with a telescopic rod, and the bottom of the telescopic rod is provided with a standing base.

[0013] Beneficial effects

[0014] In this utility model, a placement rack is adopted. Through the adjustment block on the placement rack, the supports on both sides of the adjustment block can be extended through the adjustment groove. The placement rack can be adjusted according to different types of gas cylinders. The supports on both sides are connected by the locking strip in the adjustment groove. For gas cylinders with smaller diameters, the excess support needs to be extended to the outside of the adjustment block. The internal locking strip is toothed. The principle is that it can be loosened by applying force left and right, and locked by applying force up and down. Therefore, it can be locked by feeling the force of the gas cylinder.

[0015] This invention incorporates a storage box, which can be used to store first-aid medications or water and towels needed for fires, for emergency treatment.

[0016] This invention employs snap-fit ​​straps and connecting straps. The elastic straps of the snap-fit ​​straps and connecting straps are as flexible as those of a vehicle seat belt, allowing for free extension and retraction. They can also be mechanically and electromagnetically connected via snap-fit ​​connectors and snap-fit ​​blocks. Furthermore, electromagnetic attraction allows for faster positioning and quick donning, while the double-layer connection ensures its fixation.

[0017] In this invention, a stabilizing rod is used. The stabilizing rod can be extended when auxiliary support is needed. Since the weight of the gas cylinder and storage box is heavy to carry, the telescopic rod can be extended for auxiliary support. Attached Figure Description
