Description

A kind of lifesaving bracelet
Technical field:
The present invention relates to lifesaving protection technology field, more specifically to a kind of lifesaving bracelet.
Background technique:
Lifesaving bracelet can be when swimmer encounters emergency event, by opening the switch of bracelet, so that the gas in bladder tank It pours in the life saving air bag bag originally folded, the expansion of life saving air bag bag is floated on the water surface so that people floats on water Face and be not easy to sink under water, and warning effect is played to surrounding, however, in existing lifesaving bracelet, bladder tank is usually The outside of the entire main casing in lifesaving bracelet is either partially in main casing, so that it is in lifesaving bracelet main casing External part is easy collision and damaged or leakage, so that it is unable to satisfy the requirement of inflation when in use, meanwhile, it is existing Lifesaving bracelet main casing generally comprises upper housing and lower case, and lower case is fixed on watchband, and upper housing is buckled in lower case, Unlatching need manpower it is dynamic upper housing is deviate from from lower case open again, the power for needing power to use is larger, in some Special Rings In border, when human body power is not all right, just it fail to open, the effect of timely lifesaving cannot be achieved.
Summary of the invention:
The purpose of the present invention is overcoming the deficiencies of the prior art and provide a kind of lifesaving bracelet, its bladder tank is in main casing, The right end of bladder tank is in right connector sleeve, and is covered by cap, so that it is not easy to collide with extraneous, guarantees air bag Tank will not be damaged or be revealed, very convenient, meanwhile, only needing to overturn switchboard can be realized inflation, due to switching plate bulk It is small, and be by rotating opening, so that it is not necessarily to may be reversed with large force, very convenient, quickly, effect is good for unlatching.
The solution to the technical problem of the present invention is as follows:
A kind of lifesaving bracelet, including main casing, the main casing includes procapsid and back casing, after the side of procapsid is hinged on On the same side of shell, procapsid lid is closed on back casing;
