DETAILED DESCRIPTION

[0027] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.

[0028] See also Figure 1-4 The present invention provides a technical solution: a safety belt for high-altitude power work, comprising: a mounting block 1, and a connecting ring 2 arranged on the left side of the mounting block 1, a belt body 3 is connected to the left side of the connecting ring 2, and a cushion strip 4 is arranged on the inner side of the belt body 3, and also includes:

[0029] A winding rod 5 is installed inside the mounting block 1, and a connecting rod 6 is provided on the upper side of the winding rod 5, a limiting groove 7 is provided on the surface of the connecting rod 6, a first connecting block 8 is provided at the lower end of the winding rod 5, a limiting assembly 9 is provided at the upper right end of the mounting block 1, and a supporting frame 10 is provided at the lower end of the mounting block 1, a connecting plate 13 is provided at the lower end of the supporting frame 10, and a connecting frame 14 is provided at the lower end of the connecting plate 13, a limiting rod 15 is provided on the left side of the connecting frame 14, and a protective belt 16 is provided at the lower end of the connecting frame 14 to form a complete safety belt.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, the limit assembly 9 includes a hand-held rod 901 installed at the upper right end of the mounting block 1, and a limit block 902 is provided on the left side of the hand-held rod 901, and a guide rod 903 is provided on the outside of the limit block 902, and a first damper 904 is provided in the middle of the hand-held rod 901. In a specific example, the damper can adopt a spring structure. The limit block 902 is relatively engaged with the connecting rod 6, and the limit block 902 and the guide rod 903 are relatively slidingly arranged. The connecting rod 6 and the mounting block 1 are relatively rotatable, and the limit groove 7 is provided at equal angles on the surface of the connecting rod 6. The connecting ring 2 and the mounting block 1 are relatively rotatable, and the longitudinal section of the connecting ring 2 is a "D"-shaped structure. By pulling the hand-held rod 901 to the right, the hand-held rod 901 drives the limit block 902 to move to the right along the guide rod 903 to squeeze the first damper 904. At this time, the limit Block 902 relaxes the limit on the connecting rod 6 and rotates the connecting rod 6 at the same time, so that the connecting rod 6 drives the winding rod 5 to rotate along the first connecting block 8 inside the mounting block 1. At this time, the waist belt body 3 and the cushion strip 4 wrapped around the outside of the winding rod 5 are wound up. After the winding is completed, the hand-held rod 901 is relaxed to make the first damper 904 rebound and push the limit block 902 to move to the left along the guide rod 903 and engage with the connecting rod 6, thereby completing the adjustment of the length of the waist belt body 3.

[0031] like Figure 1 and Figure 4As shown, the connecting frame 14 is relatively engaged with the connecting plate 13, and the limiting rod 15 is relatively threadedly connected to the connecting frame 14 and the connecting plate 13. A second connecting block 11 is arranged inside the support frame 10, and a second damper 12 is arranged outside the second connecting block 11. The second connecting block 11 is relatively slidably arranged with the support frame 10, and the longitudinal section of the second connecting block 11 is a "T"-shaped structure. When the user falls, the connecting frame 14 is pulled and fixed by the protective belt 16, so that the connecting frame 14 drives the second connecting block 11 is displaced downward inside the support frame 10, and at this time, the second connecting block 11 squeezes the second damper 12, so that the second damper 12 is compressed and rebounds to push the second connecting block 11 to reset, thereby completing the fall buffering work of the device; at the same time, when the protective belt 16 is damaged and needs to be replaced, the limit rod 15 is rotated to make the limit rod 15 relax the limit on the connecting frame 14, and the connecting frame 14 is taken out to the downward side at this time, thereby completing the convenient disassembly work of the connecting frame 14 and the protective belt 16, thereby improving the disassembly and assembly efficiency of the device.

[0032] Working principle: When using the power aerial work safety belt, first, by placing the device on the waist and abdomen of the user, pull the hand-held rod 901 to the right at the same time, so that the hand-held rod 901 drives the limit block 902 to move to the right along the guide rod 903 to squeeze the first damper 904. At this time, the limit block 902 relaxes the limit on the connecting rod 6, and rotates the connecting rod 6 at the same time, so that the connecting rod 6 drives the winding rod 5 to rotate along the first connecting block 8 inside the mounting block 1. At this time, the belt wrapped around the outside of the winding rod 5 The main body 3 and the cushion strip 4 are rolled up to fit the belt main body 3 and the cushion strip 4 on the waist and abdomen of the user, which is convenient for fixing the device on the waist of different users and improving the installation efficiency of the device. After the rolling is completed, the hand-held rod 901 is pulled loosely, so that the first damper 904 rebounds and pushes the limit block 902 to move to the left along the guide rod 903 and engage with the connecting rod 6, and the connecting rod 6 is fixed on the upper side of the installation block 1, so that the rolling rod 5 is not easy to rotate inside the installation block 1, thereby improving the installation stability of the device;

[0033] Then, when the user falls, the connecting frame 14 is pulled and fixed by the protective belt 16, so that the connecting frame 14 drives the second connecting block 11 to move downward inside the support frame 10. At this time, the second connecting block 11 squeezes the second damper 12, so that the second damper 12 is compressed and rebounds to push the second connecting block 11 to reset, thereby completing the fall buffering work of the device; at the same time, when the protective belt 16 is damaged and needs to be replaced, the limiting rod 15 is rotated to make the limiting rod 15 relax the limit on the connecting frame 14, and the connecting frame 14 is taken out to the lower side at this time, thereby completing the convenient disassembly work of the connecting frame 14 and the protective belt 16, and improving the disassembly and assembly efficiency of the device. The above is the use principle of the safety belt for high-altitude power operations.

[0034] The implementation of the embodiments of the present invention has the following beneficial effects:

[0035] The present invention provides a safety belt for high-altitude power operations. The length of the belt can be easily adjusted during use. The length of the belt can be adjusted according to the waist circumference of different users, thereby improving the use efficiency of the device. The belt has a certain buffering and protection capability, and is not likely to cause injury to the user when the user is pulled for protection. The use safety of the device is improved, and the device has a better safety protection effect.

[0036] Specifically, in the embodiment of the present invention, the connecting rod cooperates with the first connecting block to drive the reeling rod to rotate inside the mounting block, so that the reeling rod reels the belt body and the cushion strip wound on the outside thereof, so that the device can adjust the length of the belt body and the cushion strip according to the waist circumference of different users;

[0037] The first damper cooperates with the first damper to push the limit block to move to the left, and the limit block is engaged with the connecting rod to fix the connecting rod on the upper side of the mounting block to prevent the connecting rod from rotating on the upper side of the mounting block after the device completes the adjustment of the belt body and the cushion strip.

[0038] The second connecting block cooperates with the second damper to buffer the pulling force of the connecting frame and the protective belt, so that the user is not easily pulled and damaged by the protective belt when falling, thereby improving the safety of the device;

[0039] The limit rod cooperates with the connecting plate to loosen the limit of the connecting frame. When the protective belt is damaged and needs to be replaced, the operator can easily remove the protective belt, thereby improving the disassembly and assembly efficiency of the device.

[0040] The above disclosure is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
