The invention relates to the technical field of wearable intelligent devices, and in particular discloses an application method of an intelligent caring waist belt. The intelligent caring waist belt comprises a waist belt body, a shell, an air bag, an air cylinder and a controller, wherein the waist belt body is arranged at the upper end of the outer surface of the shell in a penetrating manner, the controller is arranged on the shell, the upper end of the air bag is connected with the shell, buckles are arranged on the two sides of the lower part of the air bag, an air inlet is arranged at the upper end of the air bag, and the air cylinder is inserted in the air inlet. The application method comprises the following steps of fixing the waist belt body to the waist of a wearer; folding theair bag to the position, near the waist, of the wearer in a manner of winding from bottom to top; buckling the buckles on the two sides around the wearer; and enabling a controller to control the aircylinder to be opened for carrying out air inflation on the air bag, so that the air bag is downwards unfolded. For the application method of the intelligent caring waist belt provided by the invention, the air bag in the waist belt is unfolded downwards after being inflated for surrounding the lower part of the wearer, and thus the protecting effect on the wearer is improved.

The invention discloses a telescopic-arm blocking crossing rack, and belongs to the technical field of power line engineering. The telescopic-arm blocking crossing rack comprises rack bodies and blocking devices, wherein the rack bodies are arranged at two sides of a crossed object, the blocking devices are connected to the rack bodies, each rack body comprises a vertical post, a rotation support seat, a mast and rack body fixing pull lines, the vertical posts are arranged at the two sides of the crossed object and are fixed by the rack body fixing pull lines, the rotation support seat is connected between the mast and the vertical post, each blocking device comprises a telescopic arm, a balancing arm and a blocking rod system, the telescopic arm and the balancing arm are respectively and symmetrically arranged at two sides of the rotation support seat, a blocking rod system is attached onto the telescopic arm, and the blocking devices at the two sides of the crossed object are abutted in the air by the telescopic arms. By the telescopic-arm blocking crossing rack, rapid blocking can be achieved in the air, the blocking power-failure running time is short, a bearing framework crossed by blocking is of a rigid structure and is high in stability, the crossed object can be protected very well, meanwhile, broken line impact can be borne, the crossed object is protected within the rigid framework, and the safety guarantee during circuit crossing is improved.

The invention provides an airbag device for protecting knees and legs, which comprises a module frame. An air bag and a decoration cover for air charging system are arranged in the module frame, and a decoration cover is arranged on the module frame. The invention is characterized in that the two secondary air chambers are symmetrically arranged at two sides of the lower part of the air bag, anda notch is provided in the middle area of the lower part of the air bag; the two secondary air chambers are respectively folded into a main air chamber at the upper part of the air bag; an isolation strip is respectively arranged between the secondary air chambers and the main air chamber. When the air charge is performed, the main air chamber arranged at the upper part of the air bag is first fully charged to ensure the protection for the knees. Then, the main air chamber is continuously charged to extend the secondary air chamber so as to prevent the legs from directly contacting with the lower part of a dashboard, thereby reducing the harm to the legs, simultaneously increasing the contact area between the legs and the knees, and protecting the legs and the knees more effectively. As the broken notch is provided in the middle area of the lower part of the air bag, the airbag is kept away from the decoration cover when being extended, thus ensuring that the air bag is extended in the required direction.
