Description

Technical Field

[0001] This utility model relates to the field of springs, and in particular to a spring with a connecting component. Background Technology

[0002] A spring is a mechanical part that utilizes the elasticity of a material, allowing it to deform under external force and return to its original shape after the force is removed. It is typically made of materials such as alloy steel and comes in various shapes, including helical, plate, and rod. Springs possess excellent elasticity and are easily deformable, making them widely used in various mechanical devices for shock absorption, vibration damping, mechanism control, energy storage, and force measurement. A spring with a connecting assembly is a special design that uses this assembly to connect and secure the spring to other components, ensuring a tight connection and preventing loosening or detachment under load. During use, springs are subjected to reciprocating loads, leading to frequent deformation, stress relaxation, and constitutive distortion. This alters the microstructure and properties of the material, resulting in metal fatigue. Metal fatigue significantly degrades the performance of a spring, manifesting as reduced stiffness, decreased damping characteristics, changes in operating frequency, and even the potential for internal fatigue cracks. These changes not only reduce the spring's lifespan but also affect the stability and safety of the mechanical system, increasing system errors and potentially causing malfunctions and hazards. Utility Model Content

[0003] The main objective of this invention is to provide a spring with a connecting component, which can effectively solve the problems in the prior art.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A spring with connecting components includes a spring body. Two mounting connection structures are symmetrically fixedly installed at the upper and lower ends of the spring body. A protective hose is fixedly installed on the two mounting connection structures and inside the spring body. The protective hose consists of a protective connecting tube and a protective corrugated tube. There are two protective connecting tubes, which are respectively fixedly installed at the upper and lower ends of the protective corrugated tube. A connecting protective component is fixedly installed on the two mounting connection structures and inside the protective hose. The connecting protective component consists of a protective spring, a mounting connecting plate, and an elastic connecting strip. Several protective springs, mounting connecting plates, and elastic connecting strips are provided. The mounting connecting plates are respectively fixedly installed at both ends of the protective spring, and the elastic connecting strip is fixedly installed at one end of the mounting connecting plate.

[0006] Preferably, the mounting connection structure consists of a connecting base plate, a connecting base tube, and a threaded connecting post, wherein the connecting base tube and the threaded connecting post are respectively fixedly installed at both ends of the connecting base plate.

[0007] Preferably, the connecting base plate on the mounting connection structure is fixedly connected to the spring body, and the connecting base tube is inserted into the spring body.

[0008] Preferably, the protective hose is coaxial with the spring body and the mounting connection structure.

[0009] Preferably, the two protective connecting pipes on the protective hose are fixedly connected to the two connecting base plates on the two mounting connection structures, and the protective connecting pipes are located inside the connecting base pipe.

[0010] Preferably, the elastic connecting strip in the middle of the connecting protective member is fixedly connected to two adjacent mounting connecting plates, and the two elastic connecting strips at the edges are fixedly connected to one mounting connecting plate and also fixedly connected to two connecting base plates on the two mounting connecting structures respectively.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] By installing connecting protective components on the two mounting connection structures, the stress and impact experienced by the spring body during operation can be absorbed and dispersed. This stress dispersion effect reduces the stress concentration inside the spring body, minimizing microstructural damage caused by long-term stress concentration. Simultaneously, the connecting protective components also provide a certain buffering effect, reducing friction and wear on the spring body during deformation, thereby extending the service life of the spring body and mitigating metal fatigue. Furthermore, by installing protective hoses, the connecting protective components are protected, reducing the probability of damage and ensuring their service life and effectiveness.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a spring with connecting components includes a spring body 1. Two mounting connection structures 2 are symmetrically fixedly installed at the upper and lower ends of the spring body 1. A protective hose 3 is fixedly installed on the two mounting connection structures 2 and inside the spring body 1. The protective hose 3 consists of a protective connecting pipe 8 and a protective bellows 9. There are two protective connecting pipes 8, which are respectively fixedly installed at the upper and lower ends of the protective bellows 9. A connecting protection component 4 is fixedly installed on the two mounting connection structures 2 and inside the protective hose 3. The connecting protection component 4 consists of a protective spring 10, a mounting connection plate 11, and an elastic connecting band 12. Several protective springs 10, mounting connection plates 11, and elastic connecting bands 12 are provided. The mounting connection plates 11 are respectively fixedly installed at both ends of the protective springs 10, and the elastic connecting bands 12 are fixedly installed at one end of the mounting connection plates 11. During use, when other components apply force to the spring body 1 through the mounting connection structures 2, the spring body 1 will undergo elastic deformation. During this process, the protective springs 10 and elastic connecting bands 12 on the connecting protection component 4 will also undergo elastic deformation.

[0020] Finally, by setting connecting protective components 4 on the two mounting connection structures 2, the stress and impact experienced by the spring body 1 during operation can be absorbed and dispersed. This stress dispersion effect reduces the stress concentration inside the spring body 1, reducing microstructural damage caused by long-term stress concentration. At the same time, the connecting protective components 4 can also provide a certain buffering effect, reducing friction and wear of the spring body 1 during deformation, thereby extending the service life of the spring body 1 and slowing down the occurrence of metal fatigue. By setting protective hoses 3, the protective hoses 3 can protect the connecting protective components 4, thereby reducing the probability of damage to the connecting protective components 4, and thus ensuring the service life and performance of the connecting protective components 4.

[0021] Furthermore, the mounting connection structure 2 consists of a connecting base plate 5, a connecting base tube 6, and a threaded connecting post 7. The connecting base tube 6 and the threaded connecting post 7 are respectively fixedly installed at both ends of the connecting base plate 5. The connecting base plate 5 on the mounting connection structure 2 is fixedly connected to the spring body 1. The connecting base tube 6 is inserted into the spring body 1. During installation, the threaded connecting post 7 on the mounting connection structure 2 can be threadedly connected to other components, thereby installing the spring body 1 in the required position.

[0022] Furthermore, the protective hose 3 is coaxial with the spring body 1 and the mounting connection structure 2. The two protective connecting tubes 8 on the protective hose 3 are fixedly connected to the two connecting base plates 5 on the two mounting connection structures 2, and the protective connecting tubes 8 are located inside the connecting base tube 6. When other components apply force to the spring body 1 through the mounting connection structure 2, and the spring body 1 undergoes elastic deformation, the protective bellows 9 on the protective hose 3 will fold and contract or extend. That is, when other components drive the two mounting connection structures 2 to move closer to each other, the spring body 1 will be compressed and the protective bellows 9 will fold and contract. When other components drive the two mounting connection structures 2 to move away from each other, the spring body 1 will be stretched and the protective bellows 9 will extend.

[0023] Furthermore, the elastic connecting strip 12 in the middle of the connecting protective component 4 is fixedly connected to two adjacent mounting connecting plates 11. The two elastic connecting strips 12 at the edge are fixedly connected to one mounting connecting plate 11 and also fixedly connected to two connecting base plates 5 on the two mounting connecting structures 2 respectively. When other components drive the two mounting connecting structures 2 away from each other, the spring body 1 will be stretched, and the protective spring 10 and elastic connecting strip 12 on the connecting protective component 4 will also be stretched accordingly.
