[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1: Please refer to Figures 1-4 This utility model provides a technical solution: an inflatable waist support belt, comprising: a belt body 1, which serves as the main body of the entire waist support belt; Velcro 2 is fixedly installed on both sides of the belt body 1, which facilitates the wearing of the entire waist support belt; an elastic storage rope 3 is provided on one side of the Velcro 2, which facilitates the storage of the entire waist support belt; an airbag assembly 4 is provided in the middle of the belt body 1, which includes a main airbag 5 and a connecting airbag 6, both of which are arranged in a linear array and are arranged perpendicularly to each other; a flexible carbon fiber heating plate 7 is provided between the main airbag 5 and the connecting airbag 6, which is electrically connected to an external controller; an air tube 8 is fixedly connected to one end of the belt body 1 and the side of the main airbag 5, which facilitates the inflation of the airbag; and a removable air cap is provided on the air tube 8, which facilitates the sealing of the air tube 8.

[0024] Connect the air tube 8 to an external miniature air pump to inflate the airbag assembly 4. Under the connection of the connecting airbag 6, both the main airbag 5 and the connecting airbag 6 are inflated with gas. After inflation, the waist is effectively supported. The main airbag 5 provides primary support, while the connecting airbag 6 provides auxiliary support while connecting the gas. The vertical connection structure forms a multi-directional force transmission path, which provides longitudinal support through the main airbag 5 and laterally disperses the pressure peak through the connecting airbags 6, avoiding muscle compression ischemia caused by pressure in one direction. In addition, when the body bends over, the vertical layout of the main airbag 5 and the connecting airbag 6 can automatically adjust the contact area according to the curvature of the lumbar spine. The dynamic balance of air pressure between the airbags achieves continuous fit during waist bending, reducing the risk of the brace shifting. The belt body 1 can be quickly put on by the adhesion between the two Velcro straps 2, improving the convenience of use. In addition, the elastic storage rope 3 can be used to store the belt body 1 when not in use, making it convenient for the next use.

[0025] Example 2: Based on Example 1, one of the Velcro 2 has a bristle side 9 on one side, and the other Velcro 2 has a soft side 10 on one side. Through the adhesion of the soft side 10 and the bristle side 9, the belt 1 can be quickly worn around the waist. One end of the elastic storage cord 3 is fixedly connected to the belt 1, and a silicone strip 11 is provided on one side of the elastic storage cord 3. The silicone strip 11 is fixedly connected to the belt 1 on one side and is positioned at the edge of the belt 1. The silicone strip 11 allows the belt 1 to be attached to the waist. When fitted around the waist, it improves overall comfort. A groove 12 is provided on one side of the silicone strip 11, and a hook 13 is provided on the other side of the silicone strip 11. The groove 12 is fixedly connected to the belt body 1, and the hook 13 is fixedly connected to the belt body 1 through an elastic band 14. The groove 12 and the hook 13 are hooked together. After the belt body 1 is initially fixed by the Velcro 2, the hook 13 can be hooked onto the groove 12 by pulling the elastic band 14, thereby further improving the stability of the belt body 1 and preventing it from falling off during use.

[0026] Example 3: Based on Example 2, the main airbag 5 and the connecting airbag 6 are both fitted and fixedly installed inside the belt body 1. The surface of the belt body 1 is provided with ventilation holes 15. The ventilation holes 15 can increase the comfort of the entire waist support belt. The ventilation holes 15 are symmetrically arranged about the center plane of the belt body 1. Both ends of the connecting airbag 6 are connected to one side of the main airbag 5. The other side of the main airbag 5 is fixedly connected to the air nozzle base 16. A rubber plug 17 is inserted into one side of the air nozzle base 16 and is interference-fitted with the air nozzle base 16. The rubber plug 17 can be inserted and removed from the air nozzle base 16. The rubber plug 17 is fixedly connected to the outer wall of the air nozzle base 16 through a rubber band 18. One side of the flexible carbon fiber heating plate 7 is fixedly installed inside the belt body 1. The flexible carbon fiber heating plate 7 is electrically connected to the external control device. The other side of the flexible carbon fiber heating plate 7 is fixedly connected to a flexible heat-conducting plate 19.

[0027] The flexible carbon fiber heating pad 7 is heated by sending instructions through an external controller. The heat is evenly conducted and diffused through the flexible heat-conducting pad 19, thereby avoiding local overheating and providing heat therapy to improve blood circulation, reduce lumbar spine pressure, and relieve lumbar muscle strain. In addition, several ventilation holes 15 are provided for ventilation, further improving the user's comfort. After the lumbar support belt is used up, the rubber plug 17 on the air nozzle base 16 of each main airbag 5 can be pulled out to quickly expel the gas from the main airbag 5 and the connecting airbag 6, which facilitates subsequent storage and use.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
