Description

Technical Field

[0001] The invention relates to the technical field of lifesaving equipment, in particular to a helium anti-drowning belt. Background Art

[0002] There are many kinds of water sports, including the common swimming, surfing, speedboat, motorboat, fishing, rafting, water park, wild swimming in rivers, etc., which are not only interesting but also good for fitness, so they are deeply loved by people. Although each swimming place has certain safety measures, there are still a large number of drowning incidents every year, especially for rivers, lakes and seas with weak supervision. For example, if swimming enthusiasts feel unwell during swimming, such as cramps, etc., accidents occur during surfing, speedboat riding, motorboat riding, etc., which may lead to drowning of waders. Traditional life buoys have defects such as inconvenient storage and carrying, and unsightly appearance.

[0003] In view of the above problems, the prior art (publication number CN205707239U) discloses an anti-drowning lifesaving belt, comprising a lifesaving gas generating device, a belt body, a lower flange, an upper flange, a connecting seam, a protective cover, a safety buckle, a safety buckle mother body, a safety buckle child body, a safety buckle jack, a safety buckle plug, a folding airbag, an electronic ignition detonating device, a start button, a gunpowder tube, gunpowder, sodium azide and ammonium nitrate, an air jet, and a filter. The present invention provides an anti-drowning lifesaving belt. By opening the protective cover and pressing the start button, the electronic ignition detonating device rapidly decomposes the gunpowder inside the detonating gas generating device and the sodium azide and ammonium nitrate outside the gunpowder to generate a large amount of gas, which fills the folding airbag. The folding airbag is ejected from the connecting seam of the upper and lower flanges outside the belt body under the action of the internal gas pressure to form a lifebuoy. Since the folding airbag is arranged inside the belt body, the belt body can be relatively small in size and can be easily worn on the body, so as to play a role in emergency situations.

[0004] However, during use, the life-saving belt cannot be adjusted in size according to different users because the size of the belt is fixed, thereby reducing the adaptability of the life-saving belt during use. Summary of the invention

[0005] Purpose of the invention: The main technical problem solved by the present invention is to provide a helium anti-drowning belt, which can solve the problem that the size of the life-saving belt cannot be adjusted according to different users due to the fixed size of the belt.

[0007] Furthermore, the connecting device includes a connecting block, a connecting groove is symmetrically opened on the left side of the middle part of the upper and lower parts of the connecting block, a spring is fixed to the bottom of the connecting groove, a connecting column is fixed to the end of the spring away from the bottom of the connecting groove, a connecting hole is opened on the right side of the middle part of the upper and lower parts of the connecting frame, the connecting block is inserted into the right side of the interior of the connecting frame, and the connecting column is inserted into the interior of the connecting hole.

[0008] Furthermore, the adjustment device includes an adjusting belt, the left end of the adjusting belt is fixed to the middle of the right end of the belt body, the right side of the lower inner wall of the connecting frame is rotatably connected with an adjusting shaft, the left sides of the upper and lower inner walls of the connecting frame are jointly rotatably connected with a driven shaft, the outer walls of the adjusting shaft and the driven shaft are jointly penetrated by a transmission belt, the right side of the rear surface of the adjusting belt is fixed to the left side of the front surface of the transmission belt, an adjusting handle is fixed to the top of the adjusting shaft, and a nut is screwed on the upper part of the outer wall of the adjusting shaft.

[0009] Furthermore, the helium tank is provided with a button.

[0010] Furthermore, the outer wall of the connecting block is fitted with the inner wall of the connecting frame.

[0011] Furthermore, a thread matching the nut is formed on an upper portion of an outer wall of the adjusting shaft.

[0012] Beneficial effects: Compared with traditional lifebuoys, this belt is more convenient to store and carry, and also more beautiful. The connection device can be used to quickly put on the belt. Press the connection column and insert the connection block into the right side of the connection frame. When the connection column and the connection hole are relative, under the elastic force of the spring, the connection column is inserted into the inside of the connection hole to complete the wearing of the belt. When the belt needs to be taken off, press the connection column to separate the connection block and the connection frame to take off the belt. The adjustment device can be used to adjust the size of the belt according to the user. When adjusting the size of the belt, first loosen the nut, and then according to the needs of the user, turn the adjustment shaft clockwise or counterclockwise through the adjustment handle to drive the transmission belt to rotate through the driven shaft, thereby lengthening or shortening the adjustment belt to adjust the size of the belt. After the adjustment is completed, tighten the nut so that the bottom of the nut is pressed against the top of the connection frame to fix the adjustment shaft. BRIEF DESCRIPTION OF THE DRAWINGS
