[0013] 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.

[0014] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] Reference Figure 1-2 This utility model provides a spherical support with anti-detachment function, including a lower support plate 1, a base basin 2 fixedly connected to the lower support plate 1, an arc groove 3 on the top surface of the base basin 2, an upper support plate 4 above the lower support plate 1, a flat liner 5 fixedly connected to the bottom surface of the upper support plate 4, a spherical crown steel liner 6 below the liner 5, and the spherical crown steel liner 6 slidingly adapted to the arc groove 3; two side vertical plates 7 fixedly connected to the lower support plate 1, the side vertical plates 7 being located on both sides of the base basin 2, and two intermediate vertical plates 8 fixedly connected to the bottom surface of the upper support plate 4, the intermediate vertical plates 8 being located between the side vertical plates 7 and the base basin 2; a first anti-detachment component is installed between the intermediate vertical plates 8 and the base basin 2; a second anti-detachment component is installed between the intermediate vertical plates 8 and the side vertical plates 7. By fixing the side vertical plate 7 on the lower support plate 1 and fixing the middle vertical plate 8 on the upper support plate 4, and by installing the first anti-detachment component between the middle vertical plate 8 and the bottom basin 2, and installing the second anti-detachment component between the middle vertical plate 8 and the side vertical plate 7, external vibrations can be absorbed when vibration occurs, and the movement stroke of the upper support plate 4 can be limited so that it will not detach.

[0016] Further optimizing the design, the first anti-detachment component includes two first connecting plates 9 rotatably connected to the side vertical plate 7 and two second connecting plates 10 rotatably connected to the side wall of the base 2. The first connecting plates 9 and 10 are arranged in a one-to-one correspondence, and are rotatably connected via a rotating shaft. A rotating seat 11 is rotatably connected to the rotating shaft. A limiting cylinder 12 is fixedly connected to one rotating seat 11, and a limiting post 13 is fixedly connected to the other rotating seat 11. The limiting post 13 slides within the limiting cylinder 12. A compression spring 14 is fixedly connected between the two rotating seats 11. During movement, the upper support plate 4 compresses or stretches the compression spring 14 via the first connecting plates 9 and 10, using the compression spring 14 to absorb kinetic energy and reduce the movement of the upper support plate 4.

[0017] A further optimized design includes a fixed cylinder 15 fixedly connected to the rotating seat 11, which is fixedly connected to the limiting post 13. The limiting post 13 is located inside the fixed cylinder 15. Rubber pads 16 are fixedly connected to the side walls of the base 2 and the middle vertical plate 8, respectively, with the rubber pads 16 corresponding to the fixed cylinder 15. By aligning the rubber pads 16 with the fixed cylinder 15, when the compression spring 14 is compressed to its limit position, the rubber pads 16 abut against the fixed cylinder 15, thereby limiting the maximum movement distance of the upper support plate 4 and preventing it from slipping out.

[0018] Further optimizing the design, the second anti-detachment component includes several buffer rings 17 located between the middle vertical plate 8 and the side vertical plates 7. The buffer rings 17 are fixedly connected to the middle vertical plate 8 and are in contact with the side vertical plates 7. The buffer rings 17 are elastic steel rings. The elastic buffer rings 17 absorb kinetic energy and buffer the upper support plate 4 when it shifts, thereby reducing the movement of the upper support plate 4. Simultaneously, because the buffer rings 17 have a compression limit, they can limit the maximum movement distance of the upper support plate 4, thus preventing detachment.

[0019] To further optimize the design, a flat wear-resistant plate 18 is installed between the flat liner 5 and the spherical crown steel liner 6. The flat wear-resistant plate 18 is fixedly connected to the spherical crown steel liner 6, and the bottom surface of the flat liner 5 slides in contact with the top surface of the flat wear-resistant plate 18. A spherical wear-resistant plate 19 is installed between the spherical crown steel liner 6 and the top surface of the base 2. The spherical wear-resistant plate 19 is fixedly connected to the bottom wall of the arc-shaped groove 3, and the spherical crown steel liner 6 slides in contact with the spherical wear-resistant plate 19. The flat wear-resistant plate 18 and the spherical wear-resistant plate 19 reduce friction at the contact points, reduce wear, and increase service life.

[0020] The design is further optimized by fixing an upper mounting column 20 to the top surface of the upper support plate 4, and fixing a lower mounting column 21 to the bottom support plate 1. This facilitates the installation of the upper support plate 4 and the lower support plate 1.

[0021] The working process of this utility model is as follows: When the upper support plate 4 is displaced under the action of external force, it will squeeze or pull the first connecting plate 9 and the second connecting plate 10, thereby pulling or compressing the compression spring 14, which absorbs kinetic energy. At the same time, the buffer ring 17 between the middle vertical plate 8 and the side vertical plate 7 provides buffering, reducing the movement range of the upper support plate 4. Since the buffer ring 17 has a compression limit and the angle between the first connecting plate 9 and the second connecting plate 10 has a limit, the upper support plate 4 will not detach.

Therefore, they should not be construed as limitations on this utility model.

[0023] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
