Description

Technical Field

[0001] The utility model belongs to the technical field of air respirators, in particular to an air respirator bracket. Background Art

[0002] An air respirator is a self-contained open air respirator. It is widely used in firefighting, chemical industry, shipping, petroleum, smelting, warehouse, laboratory, mining and other departments. It is used by firefighters or emergency rescue personnel to safely and effectively extinguish fires, carry out emergency rescue and rescue work in various environments such as thick smoke, toxic gas, steam or hypoxia. Since the long-tube air respirator is equipped with a body, the body needs to be carried when in use, which makes the user inconvenient to move. Therefore, in order to facilitate the movement of the body, an air respirator bracket is needed.

[0003] Through research and analysis, it was found that the bottom of the body of the existing long-tube air respirator is provided with a placement base for supporting the body. Therefore, when the long-tube air respirator needs to be moved, the user needs to manually lift it up and move it, so it has the disadvantage of being inconvenient to move. If it is placed on a cart for movement, although its flexibility can be improved, it is difficult to brake the cart, which may easily cause the device to be too flexible. In addition, when the long-tube air respirator is placed on the cart, it is easy to cause the long-tube air respirator to fall due to the lack of fixing components. In addition, the air supply hose connected to the long-tube air respirator is relatively long, and its body is not provided with a corresponding storage component. If the hose is disassembled after use, this increases the time for preparation before use. Utility Model Content

A hook 4 is provided on one side, and the pull ring A303 extends to the outside of the other side of the bracket 1, and the connecting rope is guided by the guide wheel, and the pull ring A303 and the hook 4 are hung. The staff uses the brake caster 101 to move the bracket 1 to an appropriate position, and then locks the brake caster 101 and releases the hook between the pull ring A303 and the hook 4, so that the force-storing spring pops out the movable column 302 to make it move in the movable cavity 103, so that the friction-increasing pad 301 of the fixed base 3 contacts the ground, and the bracket 1 is further braked by increasing the friction.

[0023] Reference Figure 1 , 2 In this embodiment, the storage mechanism includes a winding column 7, a support rod 701, and a magnetic layer 8, wherein a winding column 7 is arranged on the other side of the top of the bracket 1, and support rods 701 are arranged on both sides of the winding column 7, and the number of support rods 701 is several and arranged in a longitudinal direction, and the surface of the winding column 7 and the surface of the gas hose 202 are both provided with a magnetic layer 8 in contact with each other, and the magnetic pole of the magnetic layer 8 on the surface of the gas hose 202 is opposite to the magnetic pole of the magnetic layer 8 on the surface of the winding column 7.

[0026] Reference Figure 1-3 In this embodiment, the air respirator 2 is electrically connected to an external power source.

[0027] Working principle: First, the staff pulls the pull rings B502 on both sides of the installation slot seat 5 to return the clamping block 501 to its original position, and then fits the base 201 of the air respirator 2 with the corresponding installation slot seat 5, and then releases the pull ring B502 to make the clamping block 501 fit with the corresponding clamping slot 6 under the action of the torsion spring, thereby completing the installation and fixation of the air respirator 2, and then, the staff uses the brake caster 101 to move the bracket 1 to an appropriate position, and then locks the brake caster 101 and releases the connection between the pull ring A303 and the hook 4, so that the stored force spring pops out the movable column 302 to make it move in the movable cavity 103, so that the friction pad 301 of the fixed base 3 The air hose 202 is in contact with the ground, and the bracket 1 is further braked by increasing the friction force.
