Further, an air cushion 8 is embedded in the leg binding ring 1-1, the air cushion 8 is connected with the lower end of an air pipe 9, and the upper end of the air pipe 9 is connected with an air supply mechanism 11. The contact area between the air cushion 8 and the legs is effectively increased in the structure, and the comfort degree of the legs during binding can be effectively improved when the air cushion 8 is full of air. The embodiment of the air supply mechanism provided by the invention comprises the following steps: as shown in fig. 5, 6 and 7, the air supply mechanism is arranged in the back buckle 6, the air supply mechanism 11 comprises a box body 11-1, and the box body 11-1 is formed by assembling a box cover 11-1-2 and a box body 11-1-1; an extruder 11-2 is installed in the box body 11-1-1, the extruder 11-2 comprises a main board 11-2-1, an extrusion rod 11-2-3 is arranged at the bottom of the main board 11-2-1, vertical elastic pieces 11-2-2 are arranged on two sides of the extrusion rod 11-2-3, a pull belt 11-2-4 is fixed at the top of the main board 11-2-1, and the pull belt 11-2-4 protrudes out of the box body 11-1; a slotted hole for the drawstring to penetrate through is formed in the box cover 11-1-2, a circular through hole is formed beside the slotted hole, a downward extending extrusion pipe 11-1-3 is installed in the circular through hole, an air bag 11-1-4 is arranged in the extrusion pipe 11-1-3, and the air bag 11-1-4 is vertically opposite to the extrusion rod 11-2-3; the opening of the air bag 11-1-4 is connected with the extrusion tube 11-1-3. The elastic member 11-2-2 may be a spring.

The upper end of the drawstring 11-2-4 is provided with a through hole for connecting the lifting rope 7. As shown in fig. 8, one end of the lifting rope 7 of the present invention is fixedly connected with a U-shaped ring 13, the other end is fixedly connected with a connecting member 14, and the top end of the connecting member 14 is fixedly connected with a square ring 15. The square ring 15 is connected with a bolt piece, and the U-shaped ring 13 is connected with a bolt sleeve.

The body of the trachea 9 of the present invention preferably extends between the shoulder 3, waist 2 and leg straps 1. The trachea of the structure is of an invisible structure, so that the trachea is prevented from being wound around a human body, and meanwhile, the trachea in the safety belt is not easy to damage.

The U-shaped ring 13 of the lifting rope 7 is connected with the drawstring 11-2-4, the square ring 15 is connected with a fixed pile, and the fixed pile is a building fixed structure. The lifting rope 7 is tensioned to pull the pull belt 11-2-4 and the main board 11-2-1 to move upwards, the extrusion rod 11-2-3 extrudes the air bag 11-1-4, so that air in the air bag 11-1-4 is pressed into the air cushion 8 through the air pipe 9, the air cushion 8 is expanded, the phenomenon that the thigh is tightened by the leg binding ring 1-1 when the lifting rope 7 is tensioned is avoided, and the phenomenon that the forward movement of a worker is influenced by the tightening of the legs is avoided.

The invention is further described in the following by combining the operation process of the above scheme:

firstly, the leg strap 1-1 of the safety belt of the invention is sleeved on the leg, and the fastener 4 is opened to lead the waistband 2 and the oxter strap 5 to be tied on the body.

The width of the shoulder strap 3 can be adjusted according to the needs of the user, and if the shoulder is wide or the body is fat, the width increasing strap can be pulled out of the width increasing strap 10 and fixed. For a worker with a small size, the widening band 10 can be hidden in the shoulder belt interlayer 3-1.

After the shoulder straps 3 are adjusted in width, the lifting ropes 7 are installed.

In the prior art safety belt, when the lifting rope 7 is tightened, the leg strap 1 tightens the thigh of the worker, so that the worker is uncomfortable in working. When the lifting rope 7 tensions the safety belt, the invention inflates the leg belt, and the air cushion 8 swells to achieve the effect of thickening or widening the leg binding ring 1-1, thereby protecting the legs of workers.

Preferably, the air bag 11-1-4 is provided with a one-way valve I, and the air pipe 9 is provided with a one-way valve II. In the multiple extrusion process of the air bag, the air space is repeatedly filled into the air bag through the one-way valve, and the space in the air bag only can flow to the air pipe. The structure is suitable for the condition that the capacity of the air bag is small, and enough air in the air pipe 9 and the air cushion 8 can be filled through multiple operations.
