[0017] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present invention by illustrating examples of the present invention.

[0018] like Figure 1-2 As shown, the utility model provides a technical solution for the anti-loosening structure of the locking shaft and the bracket shaft of the pneumatic cradle: comprising a cradle 11, a pull handle 12 is arranged on the main structure of the cradle 11, and a locking shaft 21 is assembled inside the pull handle 12. The function of the locking shaft 21 is to lock the pull handle 12 when necessary to ensure the stability and safety of the cradle 11 under various working conditions. The design of the locking shaft 21 matches the internal structure of the pull handle 12, which is easy to operate and control.

[0019] The tail portion of the cradle 11 is provided with a clamp assembly 3, which is mainly used to fix and support the cradle 11 to ensure its stability during use. A support shaft 22 is provided between the clamp assembly 3 and the cradle 11, and the end surfaces of the support shaft 22 and the locking shaft 21 are both provided with a cone 23.

[0020] On the corresponding outer walls of the cradle 11 and the handle 12, there is a through tapered hole 13. The cone 23 cooperates with the tapered hole 13 so that the cradle 11 can be limited when subjected to torque. This design improves the stability of the entire device.

[0021] In order to prevent the cradle 11 from loosening when subjected to torque, anti-loosening components are respectively provided at both ends of the support shaft 22 and the locking shaft 21. These anti-loosening components include a positioning seat 41, which is arranged in an L shape, and a plurality of positioning seats 41 are evenly distributed along the outer periphery of the shaft. The positioning seat 41 is connected to the outer wall of the shaft and is fixed to the locking shaft 21 and the support shaft 22 by screws 43.

[0022] In addition, the outer wall of the positioning seat 41 is connected to the anti-loosening spring 42. The anti-loosening spring 42 is located on the bracket shaft 22 and the locking shaft 21, and its end face is against the outer wall of the pull handle 12 and the cradle 11. Through the elastic action of the anti-loosening spring 42, the tapered hole 13 and the tapered groove 23 can be matched to further prevent the bracket shaft 22 and the locking shaft 21 from loosening.

[0023] In summary, the synergy between the handle 12, locking shaft 21, clamping hoop assembly 3, bracket shaft 22, cone 23, cone hole 13, anti-loosening assembly and anti-loosening spring 42, etc., this design has broad prospects and promotion value.

[0024] In this embodiment, the anti-loosening spring 42 provides elastic extrusion, and the cooperation between the cone 23 and the cone hole 13 can always keep the locking shaft 21 and the bracket shaft 22 tightened and limited to prevent loosening, without affecting the flexible rotation of the shaft body, reducing the investment in accessories, reducing losses, reducing workers' maintenance time and increasing production.
