[0018] The utility model is further described below in conjunction with the accompanying drawings.

[0019] As attached Figures 1 to 5 An emergency escape jacket that can be quickly put on and taken off using magnetic force is shown. Figure 1 and 2 The protective clothing 1 includes a first placket 4 and a second placket 5. A plurality of a magnetic buckles 2 are arranged in an array along the length direction on the first placket 4, and a plurality of b magnetic buckles 3 are arranged in an array along the length direction on the second placket 5; the plurality of a magnetic buckles 2 correspond to the plurality of b magnetic buckles 3 one by one; the a magnetic buckles 2 and the b magnetic buckles 3 are both strip-type structures, a permanent magnet 6 is arranged at both ends of the a magnetic buckle 2, and b permanent magnet 7 is arranged at both ends of the b magnetic buckle 3; when the a magnetic buckle 2 and the b magnetic buckle 3 are magnetically attracted to each other, the two a permanent magnets 6 and the two b permanent magnets 7 are magnetically attracted to each other; in order to avoid excessive weight and accuracy of magnetic attraction, the a magnetic buckle 2 and the b magnetic buckle 3, except for the a permanent magnet 6 and the b permanent magnet 7, are made of lightweight non-magnetic materials such as nylon, hollow aluminum, etc.

[0020] There is a separation inhibition structure on the combination of a magnetic buckle 2 and b magnetic buckle 3, so that when the mutually magnetically attracted a magnetic buckle 2 and b magnetic buckle 3 have a tendency to separate, the separation inhibition structure inhibits the separation of a magnetic buckle 2 and b magnetic buckle 3, and generates a negative pressure adsorption force between a magnetic buckle 2 and b magnetic buckle 3 to inhibit separation. The specific structure is as follows:

[0021] like Figure 3 , 4 5. The separation inhibition structure includes a first notch 10 and a second notch 11 on b magnetic buckle 3, and a first convex plug 8 and a second convex plug 9 on a magnetic buckle 2, the first convex plug 8 and the second convex plug 9 are both made of elastic silicone or rubber; the first convex plug 8 and the second convex plug 9 are respectively inserted into the first notch 10 and the second notch 11, and the first convex plug 8 and the second convex plug 9 are in a slight interference fit relationship with the first notch 10 and the second notch 11; in order to make the first convex plug 8 and the second convex plug 9 more smoothly inserted into the first notch 10 and the second notch 11, the outer end contours of the first notch 10 and the second notch 11 are both provided with conical chamfers 13.

[0022] b A negative pressure cavity 15 is arranged inside the magnetic buckle 3, and the negative pressure cavity 15 connects the inner end of the first recess 10 with the inner end of the second recess 11; b A one-way conducting hole 12 which is internally connected to the negative pressure cavity 15 is arranged on one side of the magnetic buckle 3, and a one-way valve is arranged in the one-way conducting hole 12, which is a common duckbill one-way valve. The one-way valve only allows the gas in the negative pressure cavity 15 to be discharged through the one-way conducting hole 12, and the external air cannot enter the negative pressure cavity 15 through the one-way conducting hole 12.

[0023] Working principle of enhanced adsorption force of a magnetic buckle 2 and b magnetic buckle 3:

[0024] When the user performs the buckling action, when the corresponding a magnetic buckle 2 and b magnetic buckle 3 approach each other, a magnetic buckle 2 and b magnetic buckle 3 automatically approach each other under the mutual attraction of a permanent magnet 6 and b permanent magnet 7, so that a magnetic buckle 2 and b magnetic buckle 3 spontaneously approach each other under the action of magnetic attraction and form a whole, so that the first convex plug 8 and the second convex plug 9 are gradually sealed and inserted into the first recess 10 and the second recess 11. In the process of the first convex plug 8 and the second convex plug 9 being gradually sealed and inserted into the first recess 10 and the second recess 11, the first convex plug 8 and the second convex plug 9 squeeze the air in the negative pressure cavity 15, so that part of the air in the squeezed negative pressure cavity 15 is discharged to the outside through the unidirectional guide hole 12, so that the pressure in the negative pressure cavity 15 is kept basically consistent with the atmospheric pressure; when under the action of external force, a magnetic buckle 2 and b magnetic buckle When there is a tendency to separate from each other, the first convex plug 8 and the second convex plug 9 are gradually pulled outward from the first recess 10 and the second recess 11. During the process of the first convex plug 8 and the second convex plug 9 being gradually pulled outward from the first recess 10 and the second recess 11, the volume of the negative pressure cavity 15 increases, and due to the one-way valve in the one-way guide hole 12, the external air cannot enter the negative pressure cavity 15, so that negative pressure is generated in the negative pressure cavity 15, and the negative pressure forms a gradually increasing resistance to the action of the first convex plug 8 and the second convex plug 9 being gradually pulled outward from the first recess 10 and the second recess 11, thereby suppressing the tendency of the a magnetic buckle 2 and the b magnetic buckle 3 to separate from each other, thereby ensuring the stability of the a magnetic buckle 2 and the b magnetic buckle 3, and solving the problem that the simple magnetic structure is easy to separate and fall off; when separation is required, it can be forced to separate by external force.

[0025] The above are only preferred implementations of the present utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present utility model.
