[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a high-pressure equalizing ball with adaptive curved surface adjustment, including a mounting bracket 1 and an adjustment component 3. The top of the adjustment component 3 is fixedly connected to the bottom of the mounting bracket 1, and the bottom of the adjustment component 3 is fixedly connected to the top of the mounting component 2. The adjustment component 3 includes a spherical shell 31. The top of the spherical shell 31 is fixedly connected to a sliding ring 34 via a connecting rope 33, and the bottom of the connecting rope 33 is fixedly connected to the outer wall of the sliding ring 34. A limiting post 32 is slidably connected to the inner wall of the sliding ring 34. A tension spring 35 is fixedly connected to the bottom of the sliding ring 34. The top of the connecting rope 33 is fixedly connected to the outer wall of the top of the spherical shell 31, and the top of the limiting post 32 is fixedly connected to the bottom of the mounting bracket 1. When the external curved surface changes and causes the spherical shell 31 to deviate from its initial position, the tension of the tension spring 35 will cause the sliding ring 34 to move on the limiting post 32, thereby adjusting the position and angle of the spherical shell 31 so that it can conform to the curved surface of the equipment.

[0024] Mounting assembly 2 includes a main frame 21. The top of the main frame 21 is fixedly connected to a threaded post 25 via a limiting ring 24, and the inner wall of the limiting ring 24 is fixedly connected to the outer wall of the threaded post 25. The outer wall of the threaded post 25 is threadedly connected to a sub-frame 22 via a threaded shell 26, and the outer wall of the threaded shell 26 is fixedly connected to the bottom of the sub-frame 22. The inner wall of the threaded shell 26 is threadedly connected to the outer wall of the threaded post 25, and the outer wall of the limiting ring 24 is fixedly connected to the outer wall of the top of the main frame 21.

[0025] Both the main frame 21 and the sub-frame 22 are fixedly connected to the outer walls of the main frame 21 and the sub-frame 22. The fixed blocks 23 are arranged in a circular array along the central axis of the main frame 21. Both the main frame 21 and the sub-frame 22 are fixedly connected to the outer walls of the main frame 21 and the sub-frame 22. The top of the threaded column 25 is fixedly connected to the bottom of the limiting column 32. The top of the limiting ring 24 is fixedly connected to the bottom of the tension spring 35. When it is necessary to install the equipment, the threaded shell 26 can be moved on the threaded column 25 by rotating the sub-frame 22, which facilitates the installation between the main frame 21 and the sub-frame 22.

[0026] The high-pressure equalization ball is mainly composed of a mounting bracket 1, an adjustment component 3, and a mounting component 2. The top of the adjustment component 3 is connected to the bottom of the mounting bracket 1, and the bottom is fixed to the top of the mounting component 2, serving as a connection and adjustment function. The mounting bracket 1 is responsible for the installation and fixation of the equalization ball to external equipment. The ball shell 31 in the adjustment component 3 is the core carrier of the equalization function. The mounting component 2, through the cooperation of components such as the main frame 21 and the sub-frame 22, realizes the installation and adaptation of the equalization ball to different equipment.

[0027] The adjustment component 3 is the key part to realize the adaptive curved surface adjustment of the equalizing ball. Its core components include a ball shell 31, a limiting post 32, a sliding ring 34, a connecting rope 33, and a tension spring 35. The ball shell 31 is connected to the sliding ring 34 through the connecting rope 33. The sliding ring 34 is sleeved on the limiting post 32 and can slide along the limiting post 32. When the equalizing ball is installed on an external device, if there is a curved surface change on the device surface, the ball shell 31 is subjected to an external force. At this time, the ball shell 31 will drive the connecting rope 33 and the sliding ring 34 to slide relative to each other on the limiting post 32.

[0028] One end of the tension spring 35 is connected to the sliding ring 34, and the other end is connected to the limiting ring 24 in the mounting assembly 2. During the sliding process of the ball shell 31, the tension spring 35 will generate an elastic tension force, which is balanced with the external force on the ball shell 31. When the external curvature changes and the ball shell 31 deviates from its initial position, the tension of the tension spring 35 will cause the sliding ring 34 to move on the limiting post 32, thereby adjusting the position and angle of the ball shell 31 so that it can fit the curved surface of the equipment. Through the synergistic effect of the connecting rope 33, the sliding ring 34 and the tension spring 35, the ball shell 31 can adaptively adjust within a certain range to adapt to different curved surface shapes, ensuring that the distance between the pressure equalizing ball and the surface of the equipment is uniform and achieving a good pressure equalization effect.

[0029] The mounting assembly 2 mainly consists of a main frame 21, a secondary frame 22, a limiting ring 24, a threaded post 25, and a threaded shell 26. Its function is to enable the rapid installation of the equalizing ball. The main frame 21 is connected to external equipment through a fixing block 23. The fixing block 23 is arranged in a ring array along the central axis of the main frame 21, which can provide a stable mounting point and ensure that the equalizing ball will not easily shake after installation.

[0030] The threaded post 25 is fixed to the top of the main frame 21. The sub-frame 22 is threadedly connected to the threaded post 25 through the threaded shell 26. When it is necessary to install the equipment, the sub-frame 22 can be rotated to move the threaded shell 26 on the threaded post 25, thereby facilitating the installation between the main frame 21 and the sub-frame 22.

[0031] The adjusting component 3 and the mounting component 2 do not operate independently, but cooperate with each other to ensure the performance of the equalizing ball. The top of the limiting post 32 of the adjusting component 3 is connected to the mounting bracket 1, and the bottom is connected to the threaded post 25 of the mounting component 2, forming a stable connection frame. This connection method ensures that the adjusting component 3 will not affect the fixed stability of the mounting component 2 when it is making adaptive adjustments; at the same time, the adjustment of the mounting component 2 will not interfere with the adaptive action of the adjusting component 3 on the curved surface.
