Description

[0002] A spherical hinge structure usually consists of two main parts, a part with a protruding spherical projection and a part with a corresponding depression. This design enables the spherical hinge to achieve omnidirectional rotational movement while providing good support and connection functions. A spherical hinge structure is a mechanical connection device that allows free rotation in multiple axes and is widely used in applications that require high flexibility and stability.

[0003] In the prior art, the working principle of some spherical hinge structures is based on the relative movement of spherical mating, which allows two objects to move freely in multiple axes and angles. Its main purpose is to provide a reliable mechanical connection in applications that require high flexibility and stability. However, in the specific use process, the design of the spherical hinge structure makes it perform well under specific conditions, but if it cannot adapt to different load conditions, its application range will be limited. For example, in some applications that require frequent changes in the load direction or magnitude, the spherical hinge structure may not provide sufficient flexibility and stability. Therefore, in response to the above problems, a spherical hinge structure is proposed. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Referring to Figures 1 to 3 , a spherical hinge structure includes a base 1. The base 1 serves as the basic part of the entire spherical hinge structure and is usually made of high-strength steel or cast iron to ensure sufficient stability and load-bearing capacity. Fixed components for providing support force are fixedly connected to both the left and right outer sides of the base 1. Fixed components for providing support force are fixedly connected to both the left and right outer sides of the base 1 to enhance the stability and load-bearing capacity of the base 1. The design of these fixed components takes into account the structural firmness and installation convenience. The fixed component includes a support base 2. The outer part of the support base 2 is in contact with the ground to provide stable support for the entire structure. The bottom of the support base 2 may be designed with anti-slip textures or gaskets to increase friction and prevent sliding. The outer part of the support base 2 is in contact with the ground. The outer part of the support base 2 is fixedly connected to both the left and right outer sides of the base 1. Shells 3 are fixedly connected to both the left and right tops of the base 1. The shells 3 are usually made of metal materials to protect the internal mechanical components from the external environment. A column 4 is slidably connected to the top of the shell 3. The column 4 can slide up and down within the shell 3 to adapt to different height requirements. The design of the column 4 takes into account the smoothness of movement and the compactness of the structure;

[0025] At the top of the column 4, there is a ball head 5 fixedly connected. The design of the ball head 5 allows for multi-directional rotation within a certain range, increasing the flexibility of the structure. The ball head 5 is usually made of wear-resistant materials to reduce wear and extend its service life. Inside the ball head 5, there is a fixing pin 1 6 fixedly connected, which is used to firmly connect the ball head 5 to other components. The design of the fixing pin 1 6 takes into account the reliability of the connection and ease of installation. Outside the fixing pin 1 6, there is an elastic retaining ring 7 fixedly connected, which is used to provide additional buffering and protection to prevent the fixing pin 1 6 from loosening during use. The material selection of the elastic retaining ring 7 considers its elasticity and durability. Outside the ball head 5, there is a pressure ring 8 fixedly connected, which is used to further fix the position of the ball head 5 and prevent it from falling off during movement. The design of the pressure ring 8 takes into account the fastening effect and operational convenience. The outside of the ball head 5 is rotatably connected to the top beam 10. The top beam 10 can rotate in multiple directions driven by the ball head 5 to adapt to different load conditions. The design of the top beam 10 takes into account the balance between strength and flexibility. Inside the top beam 10, there is a flexible filler 9, which is usually made of rubber or similar materials and is used to absorb shocks and vibrations to protect the structure from damage. The selection of the flexible filler 9 considers its shock-absorbing effect and durability;

[0026] Referring to Figures 3 to 4 , the top beam 10 is usually made of high-strength steel or alloy materials to ensure that it can withstand large loads and stresses. Inside it, there are multiple fixing pins 2 11 fixedly connected, which are usually made of hardened steel to ensure sufficient strength and durability. The design of these fixing pins takes into account the requirements of easy installation and maintenance. They are used to enhance the structural stability and load-bearing capacity of the top beam 10. Inside the top beam 10, there are multiple fixing pins 2 11 fixedly connected. On the left and right sides of the bottom of the top beam 10, there are hydraulic cylinders 12 fixedly connected. The hydraulic cylinders 12 are used to provide power or control the movement of the top beam 10. The design of the hydraulic cylinders 12 takes into account their response speed, force output, and durability. The outside of the ball head 5 is slidably connected inside the housing 3. This design allows the ball head 5 to move freely within a certain range while maintaining the integrity of the structure;

[0027] The material selection of the ball head 5 takes into account the requirements of wear resistance and friction reduction. The outer part of the top beam 10 is rotatably connected to the outside of the ball head 5. This rotational connection design enables the top beam 10 to freely rotate in multiple directions, increasing the flexibility of the structure. The rotational connection part usually includes bearings and seals to ensure smooth movement and prevent dust from entering. The outside of the retaining ring 8 is fixedly connected to the inside of the top beam 10, which is used to further fix the position of the ball head 5 and prevent it from falling off during movement. The design of the retaining ring 8 takes into account the fastening effect and operational convenience. The outside of the circlip 7 is arranged inside the top beam 10, which is used to provide additional buffering and protection to prevent the fixing pin one 6 from loosening during use. The material selection of the circlip 7 takes into account its elasticity, durability, and fit with the inside of the top beam 10.

[0028] Working principle: First of all, the base 1, as the basic part of the spherical hinge structure, is usually made of high-strength steel or cast iron to ensure sufficient stability and load-bearing capacity. The fixing components enhance the stability and load-bearing capacity of the base 1 and are usually made of metal materials to protect the internal mechanical components from the external environment. The column 4 can slide up and down inside the housing 3 to meet different height requirements. The design of the ball head 5 allows for multi-directional rotation within a certain range, increasing the flexibility of the structure. The ball head 5 is usually made of wear-resistant materials to reduce wear and extend its service life. It is used to firmly connect the ball head 5 to other components.

[0029] The top beam 10 can rotate in multiple directions driven by the ball head 5 to adapt to different load conditions. The design of the top beam 10 takes into account the balance between strength and flexibility. The inside of the top beam 10 is provided with a flexible filler 9, usually made of rubber or similar materials, which is used to absorb shocks and vibrations and protect the structure from damage. The hydraulic cylinder 12 is used to provide power or control the movement of the top beam 10. The design of the hydraulic cylinder 12 takes into account its response speed, force output, and durability.

[0030] In this structure, components such as the base 1, support seat 2, housing 3, column 4, ball head 5, fixing pin one 6, circlip 7, retaining ring 8, top beam 10, and hydraulic cylinder 12 work together to form a stable, flexible, and durable spherical hinge structure that can freely rotate in multiple directions to adapt to different load conditions, while absorbing shocks and vibrations to protect the structure from damage.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model.
