Problems solved by technology
[0002] Existing lifejackets are large in size, which affects movement after wearing them, and the use of traditional lifejackets is narrow. After wearing a lifejacket, they can only float on the water surface, unable to complete free diving and quickly surface when danger occurs. There is also no way to tell when you need to provide buoyancy

Embodiment Construction
[0015] see figure 1 , figure 2 , a lifesaving harness, comprising a horizontally arranged ring belt 1, an arc-shaped strap 2a / ab is provided on the left and right sides of the ring belt 1, and each arc-shaped strap 2 is connected to the ring belt 1 at both ends. A battery 3, a pressure sensor 4, a switch 5 and a pull switch 6 are provided on the belt 1, and an electric trigger airbag 7a / 7b is provided on each arc-shaped strap 2a / 2b;
[0016] The pull-type switch 6 includes a housing 61, and the housing 61 is provided with two insulating rods 62 arranged in parallel. The two ends of the two insulating rods 62 are respectively provided with electrical contacts. The electrical contacts are respectively contact A and contact B, and the electrical contacts at the two ends of the other insulating rod 62 are respectively contact C and contact D, and the positions of contact A and contact C are opposite, and contact B and contact C are opposite to each other. The contact point D is...

A lifesaving strap comprises an annular belt; strap bodies are arranged on the left side and the right side of the annular belt, and the two ends of each strap body are connected to the annular belt in a bridging mode; a battery, a pressure sensor, a switch and a pull type on-off device are arranged on the annular belt, and an air bag is arranged on each strap body. The pull-type on-off device comprises a shell, two insulating rods are arranged in the shell, and two ends of one insulating rod are provided with a contact A and a contact B; the other insulating rod is provided with a contact C and a contact D, the contact A and the contact C directly face each other, the contact B and the contact D directly face each other, a spring is arranged between the two insulating rods, pull ropes are arranged on the two insulating rods, the pull ends of the pull ropes extend towards the other insulating rod, and extend out of the shell to form a pull ring; the contacts A, B, C and D respectively lead out a lead, the leads are arranged along the contours of the girdle and the strap, the lead of the contact A is connected with the corresponding air bag in series and then combined with the lead of the contact B, the lead of the contact D is connected with the air bag on the strap in series and then combined with the lead of the contact C, and the two combined leads are connected with the battery, the pressure sensor and the switch in series to form a closed loop.
Description
technical field [0001] The invention relates to a lifesaving harness. Background technique [0002] Existing lifejackets are large in size, which affects movement after wearing them, and the use of traditional lifejackets is narrow. After wearing a lifejacket, they can only float on the water surface, unable to complete free diving and quickly surface when danger occurs. There is also no way to tell when buoyancy needs to be provided. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a lifesaving harness, which is small in size and does not affect normal activities when worn, and can freely control when to provide buoyancy to protect the user's safety. [0004] In order to solve the above-mentioned technical problems, the present invention provides a lifesaving strap, which includes a horizontally arranged ring belt, and an arc-shaped strap is provided on the left and right sides of the ring belt, and the two ends...
