[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Refer to Figure 1 - Figure 3 In an embodiment provided by the present utility model: An inspection sling for tower maintenance includes a housing 1. An adjusting mechanism is provided on the inner wall of the housing 1. The adjusting mechanism includes a cylinder 9. The outer wall of the cylinder 9 penetrates and is fixedly connected to the inner wall of the housing 1, providing a fixed support effect for the cylinder 9 through the inner wall of the housing 1. The outer wall of the cylinder 9 is rotatably connected to a rotating housing 7, enabling the rotating housing 7 to rotate along the outer wall of the cylinder 9. The inner wall of the rotating housing 7 is elastically connected to the outer wall of the cylinder 9 through a volute spring 8, enabling the rotating housing 7 to always rotate in the counterclockwise direction without being affected by external forces. The outer wall of the rotating housing 7 is fixedly connected to a waist belt 6, enabling the rotating housing 7 to drive the waist belt 6 to move together when rotating. The outer wall of the waist belt 6 is rotatably and slidably connected to the inner wall of the housing 1, enabling the waist belt 6 to rotate along the inner wall of the housing 1.

[0031] Refer to Figure 1 - Figure 3, the outer wall of the rotating shell 7 is rotatably connected to the inner wall of the shell 1, enabling the rotating shell 7 to rotate along the inner wall of the shell 1. The inner wall of the shell 1 is elastically connected to a traction column 12 through a spring 13, causing the traction column 12 to always move downward without being affected by external forces. The bottom end of the traction column 12 is fixedly connected to a wedge block 14, enabling the traction column 12 to drive the wedge block 14 to move together when moving vertically. A card slot 15 is provided at the top end of the rotating shell 7, enabling the wedge block 14 to be engaged with the top end of the rotating shell 7. The outer wall of the wedge block 14 is engaged with the inner wall of the card slot 15, causing the rotating shell 7 to be fixed due to the engagement of the wedge block 14 and the card slot 15.

[0032] Refer to Figure 3 , the outer wall of the traction column 12 is slidably connected to the inner wall of the shell 1, enabling the traction column 12 to move vertically along the inner wall of the shell 1. The outer wall of the wedge block 14 is slidably connected to the inner wall of the shell 1, enabling the wedge block 14 to move vertically along the inner wall of the shell 1.

[0033] Refer to Figure 3 , a protective cover 10 is hinged to the top end of the shell 1, enabling the protective cover 10 to unfold along the top end of the shell 1 and being able to block the top end of the traction column 12, achieving the effect of preventing accidental touch. A bolt 11 penetrates and is threadedly connected to the inner wall of the protective cover 10, enabling the bolt 11 to move vertically along the inner wall of the protective cover 10 by rotation. The bottom end of the bolt 11 is threadedly connected to the top end of the shell 1, causing the protective cover 10 to be fixed to the top end of the shell 1 through the threaded connection of the bottom end of the bolt 11 and the top end of the shell 1.

[0034] Refer to Figure 2 , one end of the scroll spring 8 is fixedly connected to the outer wall of the column body 9, and the other end of the scroll spring 8 is fixedly connected to the inner wall of the rotating shell 7. When the fixation of the rotating shell 7 is released, the rotating shell 7 will drive the belt 6 to rotate counterclockwise due to the elastic force of the scroll spring 8, causing the belt 6 to wind around the outer wall of the rotating shell 7.

[0035] Refer to Figure 3 , one end of the spring 13 is fixedly connected to the inner wall of the shell 1, and the other end of the spring 13 is fixedly connected to the outer wall of the traction column 12. When the traction column 12 stops being pulled, the traction column 12 can move downward due to the elastic force of the spring 13.

[0036] Refer to Figure 1 - Figure 3 , multiple groups of card slots 15 are provided, enabling the rotating shell 7 to be fixed in more positions by the wedge block 14. A shoulder strap 2 is fixedly connected to the outer wall of the shell 1, providing a fixed support for the shoulder strap 2 through the outer wall of the shell 1. An adjustment block 3 is fixedly connected to the outer wall of the shoulder strap 2, enabling the shoulder strap 2 to be adjusted in length through the adjustment block 3.

[0037] Reference Figure 1 As shown in Figure 1 , one end of a set of belts 6 is fixedly connected to a buckle 5, providing a fixing effect for the buckle 5 through one end of the set of belts 6. One end of another set of belts 6 is fixedly connected to a socket 4, providing a fixing effect for the socket 4 through the other end of the other set of belts 6. The other end of the other set of belts 6 is fixedly connected to the outer wall of the housing 1, providing a fixing effect for the other set of belts 6 through the outer wall of the housing 1. The outer wall of the buckle 5 is engaged with the inner wall of the socket 4, enabling the two sets of belts 6 to be fixedly connected through the buckle 5 and the socket 4, thus fixing the device on the staff member.

[0038] Working principle: When using the device, first attach the device to the back of the staff member. Then, first wrap the two shoulder straps 2 around the upper body of the staff member. Then, unscrew the bolt 11 to release the fixation on the protective cover 10. Then, pull up the protective cover 10 so that the protective cover 10 no longer blocks the traction post 12. Then, pull up the traction post 12 to release the fixation on the rotating shell 7. Then, pull out the belt 6 on the right side outward so that the buckle 5 at one end of the belt 6 is inserted into the socket 4 at one end of the other set of belts 6, fixing the two sets of belts 6 together. Then, release the traction post 12, and it will move downward due to the elastic force of the spring 13 and be engaged with the card slot 15, fixing the rotating shell 7 at the designated position. Then, cover the protective cover 10 on the top of the traction post 12, and then fix the protective cover 10 on the top of the housing 1 through the bolt 11.

[0039] When it is necessary to release the fixation of the belt 6, first release the insertion of the buckle 5 and the socket 4. Then, by the above operation, open the protective cover 10. Then, pull up the traction post 12 to release the fixation on the rotating shell 7. Then, the rotating shell 7 will rotate clockwise due to the elastic force of the scroll spring 8, driving the belt 6 to retract into the housing 1. Then, release the traction post 12, making the traction post 12 move downward to fix the rotating shell 7. Then, by the above operation, fix the protective cover 10.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
