DETAILED DESCRIPTION

[0021] See also Figure 1-6 The utility model provides the following technical solutions: a safety belt, including a shoulder strap 1, an airbag 3, a shoulder strap 4, a leg strap 5, a fixing head 6 and a self-inflating device 8, and also including a hook 2, a trigger mechanism 7 and an inflating mechanism 9. The inflating mechanism 9, two shoulder straps 4 and two leg straps 5 are installed on the shoulder strap 1. A connecting belt 11 is installed on the shoulder strap 1. A hook 2 is installed at one end of the connecting belt 11. The trigger mechanism 7 is installed on the connecting belt 11. The self-inflating device 8 connected to the trigger mechanism 7 is installed on the shoulder strap 1. The airbag 3 is installed on the neck of the shoulder strap 1 and the shoulder strap 4. The self-inflating device 8 is connected to the airbag 3.

[0022] The trigger mechanism 7 includes an installation bin 71, a pull strap 72, a pull block 73, a fixed block 74 and a spring 75. The installation bin 71 is installed on the connecting belt 11. The fixed block 74 is installed on the inner wall groove of the installation bin 71 through the spring 75. The pull block 73 is slidably installed inside the installation bin 71. A groove matching the fixed block 74 is provided on the side wall of the pull block 73. The pull block 73 is connected to the self-inflating device 8. The pull strap 72 passes through the installation bin 71 and is installed on the pull block 73. Both ends of the pull strap 72 are installed on the connecting belt 11.

[0023] The length of the connecting belt 11 is adjustable, the shoulder strap 1 is used to fix the device on the upper body of the user, the leg strap 5 is used to fix the device on the leg of the user, and the shoulder strap 4 is used to install the airbag 3. When the device is in use, there is no air inside the airbag 3, and the volume of the airbag 3 is small, which reduces the impact of the airbag 3 on the user's movements and ensures the comfort of the user when working. The installation position of the airbag 3 ensures that the shape of the airbag 3 after inflation is U-shaped. After the airbag 3 is inflated, the inflated airbag 3 clamps the user's neck to prevent the airbag 3 from separating from the user, causing the working effect of the device to be affected. The installation method of the airbag 3 is not limited, as long as it is ensured that the expansion of the airbag 3 will not be hindered by the shoulder strap 1 and the shoulder strap 4. The self-inflating device 8 is connected to the airbag 3, and the airbag 3 can be inflated by the self-inflating device 8 to achieve the expansion of the airbag 3. Inflation of the airbag 3 increases the expansion speed of the airbag 3 and ensures the working effect of the device. The trigger mechanism 7 is connected to the self-inflating device 8. When the user falls, the trigger mechanism 7 triggers the self-inflating device 8, so that the airbag 3 automatically inflates during the user's falling process, ensuring the working effect of the airbag 3. The automatically triggered self-inflating device 8 also improves the safety of the device. The device can be hung near the user's working position through the hook 2 to prevent the user from accidentally falling. The connecting belt 11 is in a stress-free state after the hook 2 is hung on the working position, preventing the user from triggering the trigger mechanism 7 during normal work, causing the airbag 3 to accidentally expand, and the user's normal work is hindered. When the self-inflating device 8 is accidentally damaged, the user can manually inflate the airbag 3 through the inflation mechanism 9 to ensure the working effect of the device.

[0024] The mounting bin 71 is used to mount the pull block 73. The shape of the pull block 73 matches the shape inside the mounting bin 71, which ensures the stability of the pull block 73 during movement. When the user falls, the connecting strap 11 is pulled. At the same time, the connecting strap 11 is pulled and the pull strap 72 installed on the connecting strap 11 is pulled. The moving pull strap 72 will move with the pull block 73, and the moving pull block 73 will activate the self-inflating device 8. The position of the pull strap 72 passing through the mounting bin 71 is away from the position where the pull block 73 is fixed, which ensures the working effect of the trigger mechanism 7. The pull block 73 is moved with the straightened pull strap 72 to prevent the pull block 73 from being subjected to excessive force during the user's falling process, resulting in failure of the connection between the pull strap 72 and the pull block 73, which affects the working effect of the device. The straight drawstring 72 moves with the drawstring block 73, which also reduces the force applied to the self-inflating device 8 during the user's falling process, thereby extending the service life of the self-inflating device 8. The drawstring block 73 is fixed by the cooperation of the fixing block 74 and the spring 75, thereby ensuring the fixing effect of the fixing block 74. The side wall of the fixing block 74 facing the drawstring 72 and the position where the drawstring block 73 is connected to the self-inflating device 8 is in the shape of an inclined surface, thereby ensuring that the drawstring block 73 can push the fixing block 74 as long as it is subjected to a sufficiently large force, thereby ensuring the working effect of the device and making it convenient for the user to pull the drawstring block 73 back to its original position through the connecting rope between the drawstring block 73 and the self-inflating device 8, thereby facilitating the next use of the device. The spring 75 ensures that the fixing block 74 can quickly return to its original position after being pushed again, thereby ensuring the working effect of the fixing block 74.

[0025] Specifically, the distance between the positions where the drawstring 72 is fixed to the connecting belt 11 is greater than the length of the drawstring 72 .

[0026] The position in which the pull strap 72 is installed on the connecting strap 11 ensures that when the connecting strap 11 is straightened, the pull block 73 can move to the extreme position, thereby ensuring the working effect of the trigger mechanism 7. The pull strap 72 has a certain elasticity. When the connecting strap 11 is straightened, the pull strap 72 undergoes elastic deformation, thereby preventing the pull strap 72 from hindering the straightening of the connecting strap 11 and preventing the pull strap 72 from breaking due to excessive force when the connecting strap 11 is straightened, thereby extending the service life of the pull strap 72.

[0027] Specifically, fixing blocks 74 are symmetrically mounted on the inner wall of the mounting chamber 71 .

[0028] By providing two fixing blocks 74 , the fixing effect of the fixing blocks 74 is improved, and the stability of the pulling block 73 when the connecting belt 11 is not straightened is ensured.

[0029] Specifically, the hook 2 includes a hook body 21, a block 22, a fixing pin 23 and a movable groove 24. The hook body 21 is installed on the connecting belt 11. The movable groove 24 is provided on the side wall of the hook body 21. One end of the block 22 is rotatably installed on the movable groove 24. The other end of the block 22 is provided with a protrusion. The fixing pin 23 penetrates the protrusion of the block 22 and the hook body 21 and is then installed on the hook body 21.

[0030] Through the cooperation between the hook body 21 and the stopper 22, the position to be fixed can be sealed inside the hook body 21, and the stopper 22 is fixed by the fixing pin 23. The fixing pin 23 cooperates with the stopper 22 and the hook body 21, thereby fixing the device. The movable groove 24 is used to receive the stopper 22. The shape of the movable groove 24 should ensure that the rotation of the stopper 22 will not be hindered. When the hook 2 is rusted due to long-term exposure to a humid external environment, the fixing method of the stopper 22 can reduce the impact on the working effect of the hook 2 and extend the service life of the hook 2.

[0031] Specifically, the inflation mechanism 9 includes a fixing belt 91 , an inflatable airbag 92 and a mounting belt 93 . The mounting belt 93 is installed on the shoulder strap 1 , the inflatable airbag 92 connected to the airbag 3 is installed on the mounting belt 93 , and two fixing belts 91 are installed on the mounting belt 93 .

[0032] The mounting strap 93 is used to install the fixing strap 91 and the inflatable airbag 92. The airbag 3 can be inflated by pressing the inflatable airbag 92. When the self-inflating device 8 is damaged and cannot be used, the user can inflate the airbag 3 through the inflatable airbag 92 to ensure the working effect of the device. The inflatable airbag 92 and the mounting strap 93 can be fixed by the fixing strap 91, so that the inflatable airbag 92 and the mounting strap 93 fit the user's arm, thereby preventing the inflatable airbag 92 and the mounting strap 93 from moving during the user's work, causing obstruction to the user's work.

[0033] Specifically, the fixing belt 91 is installed at the upper arm and the lower arm of the user, and the inflatable airbag 92 is installed inside the installation belt 93 .

[0034] The installation position of the fixing belt 91 ensures the fixing effect of the fixing belt 91. The installation position of the fixing belt 91 is not at the joint of the user's arm to avoid affecting the user's movements. The mounting belt 93 can protect the inflatable airbag 92 installed inside the mounting belt 93 to avoid the inflatable airbag 92 from being damaged during the user's work, which will affect the working effect of the inflatable airbag 92.

[0035] Specifically, straps are installed on the shoulder straps 4 , and a fixing head 6 is installed on the strap of one of the shoulder straps 4 .

[0036] The airbag 3 can be fixed by the cooperation of the strap installed on the shoulder strap 4 and the fixing head 6, which improves the stability of the device and ensures the working effect of the airbag 3.

[0037] The working principle and use process of the utility model are as follows: the user puts on the shoulder strap 1 and the leg strap 5, fixes the airbag 3 through the cooperation of the strap of the shoulder strap 4 and the fixing head 6, fixes the inflatable airbag 92 and the installation belt 93 on the user's arm through the fixing belt 91, pulls out the fixing pin 23, rotates the stopper 22, installs the hook body 21 to the position to be fixed, rotates the stopper 22 back to its original position, and fixes the stopper 21 through the cooperation of the fixing pin 23, the stopper 22 and the hook body 21. 22 is fixed on the hook body 21. When the user falls, the connecting belt 11 is straightened. As the connecting belt 11 moves, the drawstring 72 is straightened. The straightened drawstring 72 pulls the pull block 73. The pull block 73 pushes the fixed block 74 and then starts to move. The moving pull block 73 starts the self-inflating device 8. The self-inflating device 8 inflates the airbag 3, and the airbag 3 starts to expand. When the self-inflating device 8 is damaged, the user can inflate the airbag 3 by pressing the inflatable airbag 92.
