Description

Technical Field

[0001] The utility model relates to the technical field of inflatable sports backpacks, in particular to an emergency life-saving inflatable sports backpack. Background Art

[0002] The emergency life-saving inflatable sports backpack is a kind of equipment that provides rescue and life-saving functions in emergency situations. The emergency life-saving inflatable sports backpack drives the inflation device. In order to facilitate inflation, an automatic inflation structure is usually installed. The automatic inflation structure is generally composed of a gas storage cylinder, a one-way valve and a pull rope. The gas storage cylinder provides high-pressure gas. When the pull rope is pulled down, the one-way valve can be used to control the flow direction of the gas to achieve a rapid inflation function. This design ensures that in an emergency, buoyancy support can be quickly provided to the user for emergency life-saving. However, when in use, the pull rope is easy to accidentally touch and open the one-way valve, which has certain shortcomings. For this reason, we propose an emergency life-saving inflatable sports backpack. Utility Model Content

[0021] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0022] Some embodiments of the utility model are described below in conjunction with the accompanying drawings to provide an emergency life-saving inflatable sports backpack.

[0023] Embodiment 1:

[0024] Reference Figure 1-5 , which is the first embodiment of the utility model, provides an emergency life-saving inflatable sports backpack, including a backpack body 100, an automatic inflation device 200 and an anti-pull component 300.

[0025] Specifically, the backpack main body 100 includes a bag body 101, a right storage pocket 102 arranged on the right side of the bag body 101, and a Velcro hook surface 106 arranged at the front end of the bag body 101. The backpack main body 100 also includes a left storage pocket 103 arranged on the left side of the bag body 101, a zipper strip 104 sewn on the bag body 101, a zipper head 105 engaged with the zipper strip 104, and a shoulder strap 107 arranged on the bag body 101. When in use, the right storage pocket 102 can be used to place the automatic inflation device 200, the Velcro hook surface 106 is used to fix the automatic inflation device 200, and the cooperation of the zipper head 105 and the zipper strip 104 can close or open the bag body 101 for carrying.

[0026] Specifically, the automatic inflation device 200 includes an air bag 201 arranged at the front end of the bag body 101, a Velcro surface 202 arranged at the rear side of the air bag 201 and bonded to the Velcro hook surface 106, an air pipe 203 arranged at the right side of the air bag 201, and a one-way valve 204 arranged at the rear side of the air pipe 203 and in the right storage bag 102. The air pipe 203 is a hose. The automatic inflation device 200 also includes a gas storage bottle 205 threadedly connected to the top of the one-way valve 204 and a pull rope 206 arranged on the one-way valve 204. When in use, the pull rope 206 can be directly pulled to pull the air bag 201. When disassembling, the airbag 201 can be directly pulled until the Velcro fur surface 202 of the airbag 201 is completely separated from the Velcro hook surface 106 of the backpack body 100. After separation, the one-way valve 204 can be taken out from the right storage pocket 102, and the automatic inflation device 200 and the backpack body 100 can be completely separated, thereby achieving a quick-disassembly effect, so as to repair and replace the automatic inflation device 200.

[0027] It should be noted that the outer surface of the airbag 201 is provided with a plurality of protrusions. When in use, the plurality of protrusions can increase the space inside the airbag 201 for easier use.

[0028] Specifically, the anti-pull component 300 includes a fixed tube 301 arranged on the rear side of the one-way valve 204, an annular groove 302 opened on the outside of the fixed tube 301, a rubber ring 303 inserted in the annular groove 302, a rubber strip 304 arranged at the bottom of the rubber ring 303 and a rubber cover 305 arranged on the rubber strip 304. When in use, the pull rope 206 can be placed in the fixed tube 301 of the anti-pull component 300. Since the rubber strip 304 has a certain elasticity, the movable rubber cover 305 can be aligned with the pipe mouth of the fixed tube 301 and inserted. After the insertion, the pull rope 206 can be sealed. On the one hand, it is prevented from opening the one-way valve 204 due to accidental touch of the pull rope 206, and on the other hand, it is convenient to store the pull rope 206 for use.

[0029] Embodiment 2:

[0030] Reference Figure 1 , which is the second embodiment of the utility model, is different from the first embodiment in that it also includes a fixing rope 400, which is arranged on the left side of the bag body 101 and is wrapped around the outside of the shoulder strap 107. When in use, the fixing rope 400 is fixed to the bag body 101, and the bag body 101 can be restrained by the fixing rope 400. One end of the fixing rope 400 can be fixed on the shore, and then the drowning person in the water can be rescued through the floating backpack body 100, which increases the safety of the rescuer.

[0031] The working principle and use process of the utility model are as follows: when in use, the user can place the drawstring 206 in the fixed tube 301 of the anti-pull component 300. Since the rubber strip 304 has a certain elasticity, the movable rubber cover 305 can be aligned with the tube mouth of the fixed tube 301 and inserted. After the insertion, the drawstring 206 can be sealed, which can prevent the drawstring 206 from opening the one-way valve 204 due to accidental touch, and can facilitate the storage of the drawstring 206 for use. When disassembling, the airbag 201 of the automatic inflation device 200 can be directly pulled until the Velcro fur surface 202 of the airbag 201 is completely removed. By detaching the Velcro hook surface 106 from the backpack body 100, the one-way valve 204 can be taken out from the right storage pocket 102, and the automatic inflating device 200 and the backpack body 100 can be completely separated to achieve a quick-release effect, so as to repair and replace the automatic inflating device 200. When inflating, the rubber cover 305 of the anti-pull component 300 can be opened, and then the pull rope 206 can be directly pulled to open the one-way valve 204. At this time, the high-pressure gas in the gas cylinder 205 will enter the airbag 201 through the air pipe 203, which can be automatically inflated. After inflation, it can provide buoyancy support for rescue.

[0032] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
