Abstract
Description
Technical Field
[0001] This invention relates to the field of spring replacement technology, and in particular to a spring structure that can be easily replaced. Background Technology
[0002] In mechanical structures, springs, as key elastic elements, are widely used in various equipment, and their installation areas are often under continuous pressure. Traditional spring structures lack a mechanism to transfer the stress point during disassembly and assembly to the outer periphery of the spring body. In traditional replacement methods, operators must apply force directly to the center of the spring or use external tools to pry it open to release the pressure and complete the disassembly and installation. This operating mode has significant drawbacks: because the stress point is concentrated in the middle of the spring, the operation requires a large external force, which can easily lead to permanent deformation or structural damage to the spring; at the same time, in confined spaces or complex assembly environments, operators often lack sufficient operating space, further increasing the difficulty and time cost of replacement. Furthermore, existing structures lack an effective stress distribution mechanism, making spring replacement time-consuming and labor-intensive, unable to quickly adapt to the replacement needs of springs of different strengths, thus limiting equipment maintenance efficiency and flexibility. Summary of the Invention

[0010] Preferably, a first baffle is provided on one side of the fixed seat, a shaft is provided on the first baffle, and a second baffle is sleeved on the shaft. The first baffle and the second baffle are symmetrically positioned.

[0021] The purpose of this invention is to provide a spring structure that can be easily replaced, thereby solving the problems existing in the prior art. It allows for a wider range of operations during replacement, improving the convenience and efficiency of replacement.
[0022] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0023] Reference Figures 1 to 4As shown, a replaceable spring structure 10 includes a main body 1; a pressing device 2, which is placed on and connected to the main body 1; and a spring 3, which is sleeved on the main body 1. Through the coordinated design of the main body 1, the pressing device 2, and the spring 3, the traditional method of directly manipulating the middle area of the spring during replacement is changed. The pressing device 2 is used to transfer the force point to the outer area of the main body 1. As the force-bearing structure for disassembling and assembling the spring structure, the pressing device 2 allows for a wider range of operation when replacing the spring structure. At the same time, the fit between the spring 3 and the main body 1 simplifies the disassembly process. This design solves the problem of difficult traditional spring replacement, especially in applications requiring frequent replacement of springs of different strengths, providing greater operational convenience.
[0024] In this embodiment, the main body 1 includes a fixing base 11 and a fixing rod 12. The fixing base 11 is sleeved on the fixing rod 12. One end of the fixing rod 12 passes through the fixing base 11 and is placed outside the fixing base 11, and the other end of the fixing rod 12 passes through the fixing base 11 and is placed outside the fixing base 11. The fixing rod 12 extends laterally along the spring 3, and the pressing device 2 is connected to the fixing rod 12. Through the above technical solution, the structural design of the main body 1 significantly simplifies the replacement process of the spring 3. Users only need to press both ends of the fixing rod 12 to easily complete the operation without interfering with the spring 3 itself, thereby effectively reducing the difficulty of operation and the risk of component damage.
[0025] In this embodiment, the main body 1 also includes a first limiting member 13 and a second limiting member 14, which are respectively placed on both sides of the fixed base 11; both the first limiting member 13 and the second limiting member 14 are sleeved on the fixed rod 12. The first limiting member 13 and the second limiting member 14 are used to connect with the mounting structure. The design of the first limiting member 13 and the second limiting member 14 being respectively placed on both sides of the fixed base 11 forms a bidirectional clamping mechanism. By sleeved on the fixed rod 12, the displacement range of the fixed base 11 along the axial direction of the fixed rod 12 can be effectively limited, and the assembly process can be simplified. When the spring 3 needs to be replaced, this structural design ensures the positional stability of the fixed base 11 and avoids repeated adjustment operations caused by the sliding of the fixed base 11. At the same time, this solution, combined with the cylindrical guiding characteristics of the fixed rod 12, ensures that the fixed base 11 and the fixed rod 12 will not have relative displacement, so that the entire structure can be quickly disassembled and installed while ensuring stability, thereby significantly improving the convenience of replacing the spring 3.
[0026] In this embodiment, the main body 1 further includes a first retaining ring 15 and a second retaining ring 16, both of which are sleeved on the fixing rod 12. The first retaining ring 15 is placed on the side of the first limiting member 13 away from the second limiting member 14 and limits the first limiting member 13 (restricting the first limiting member 13 from moving away from the second limiting member 14). The second retaining ring 16 is placed on the side of the second limiting member 14 away from the first limiting member 13 and limits the second limiting member 14 (restricting the second limiting member 14 from moving away from the first limiting member 13). The first retaining ring 15 and the second retaining ring 16 are respectively disposed on the outside of the first limiting member 13 and the second limiting member 14. The first retaining ring 15 and the first limiting member 13, and the second retaining ring 16 and the second limiting member 14 are in close contact, thereby effectively preventing the limiting members from sliding along the axial direction of the fixing rod 12. Because the retaining ring is fixed in position and not easily deformed, the axial positions of the two limiting components on the fixing rod 12 will not change during replacement. Consequently, the axial position of the fixing seat 11 on the fixing rod 12 will not change. The spring 3 connected to the fixing seat 11 ensures that the spring 3 maintains an accurate installation position throughout the replacement process. Operators do not need to repeatedly adjust the position of the limiting components, significantly improving replacement efficiency. Furthermore, this design complements the structure of the pressing device 2, together achieving a wider force range and easier replacement.
[0027] In this embodiment, both the first retaining ring 15 and the second retaining ring 16 are fixedly connected to the fixing rod 12.
[0028] In this embodiment, the pressing device 2 includes a first pressing member 21 and a second pressing member 22, both of which are connected to a fixing rod 12. One end of the fixing rod 12 passes through the fixing seat 11, the first limiting member 13, and the first retaining ring 15 and is connected to the first pressing member 21. The other end of the fixing rod 12 passes through the fixing seat 11, the second limiting member 14, and the second retaining ring 16 and is connected to the second pressing member 22. The first pressing member 21 and the second pressing member 22 are symmetrically designed, realizing the function of applying force simultaneously on both sides of the top of the pressure area. The fixing rod 12 passes through the fixing seat 11, the first limiting member 13, and the first retaining ring 15 and is connected to the first pressing member 21. This multi-layer nested structure utilizes the limiting effect of the first retaining ring 15 on the first limiting member 13 to ensure that the force can be stably applied to the limiting structure when pressing the first pressing member 21, preventing the component from shifting. The other end of the fixing rod 12 passes through the fixing base 11, the second limiting member 14, and the second retaining ring 16, and then connects to the second pressing member 22, forming a symmetrical force system to ensure uniform force on both sides. Users can easily compress or release the spring 3 by simultaneously operating the pressing members on both sides without the need for additional tools, significantly improving the ease of replacement.
[0029] In this embodiment, the first pressing member 21 and the second pressing member 22 are detachably fixedly connected to both ends of the fixing rod 12. Preferably, both the first pressing member 21 and the second pressing member 22 are threadedly connected to the fixing rod 12. The main body 1 is used to connect to the first mounting member 71 of the mounting structure 7. The first pressing member 21 and the second pressing member 22 are both located outside the first mounting member 71 to transfer the force point to the peripheral area of the main body 1.
[0030] In this embodiment, a first baffle 4 is provided on one side of the fixed base 11, a shaft 5 is provided on the first baffle 4, and a second baffle 6 is sleeved on the shaft 5. The first baffle 4 and the second baffle 6 are symmetrically positioned. One end of the shaft 5 is connected to the first baffle 4, and the other end of the shaft 5 passes through the second baffle 6 and is placed outside the second baffle 6. By providing a first baffle 4 on one side of the fixed base 11, the fixed base 11 serves as an extension base of the main structure, providing a stable external support point and avoiding direct force application to the compression area of the spring 3. The shaft 5 acts as a guide core, preventing the spring 3 from shifting or twisting during compression or tension. The cooperation between the second baffle 6 and the shaft 5 achieves a sliding limit function, ensuring that both ends of the spring 3 are reliably constrained while allowing the second baffle 6 to move along the shaft 5 during replacement without having to pry the spring 3. The symmetrical design of the first baffle 4 and the second baffle 6 is based on the principle of symmetrical force distribution, ensuring that the pressure is evenly distributed at both ends of the spring 3 and eliminating the risk of tilting caused by unilateral force. The fixed connection between one end of the shaft 5 and the first baffle 4 strengthens the overall rigidity, while the other end passes through the second baffle 6 and extends to the outside. The first pressing member 21 and the second pressing member 22 make it easy for the user to directly grasp or operate, thereby distributing the force points to the periphery and simplifying the disassembly and installation steps.
[0031] It should be noted that the symmetrical positions of the first baffle 4 and the second baffle 6 mean that when the spring structure is installed in the working position, the cross sections of the first baffle 4 and the second baffle 6 are symmetrical about the shaft 5.
[0032] In this embodiment, the fixed base 11 is fixedly connected to the first baffle 4, the first baffle 4 is fixedly connected to one end of the shaft 5, and the fixed rod 12 is perpendicular to the shaft 5.
[0033] In this embodiment, spring 3 is sleeved on shaft 5 and positioned between first baffle 4 and second baffle 6; one end of spring 3 abuts against first baffle 4, and the other end of spring 3 abuts against second baffle 6. It should be noted that when the spring structure is installed in the working position, the other end of spring 3 abuts against second baffle 6.
[0034] In this embodiment, a mounting structure 7 is also included, on which a first mounting member 71 and a second mounting member 72 are provided; a spring structure 10 is placed between the first mounting member 71 and the second mounting member 72.
[0035] In this embodiment, the first mounting member 71 is provided with a first latch 711 and a second latch 712 corresponding to each other; the first limiting member 13 is provided with a first engaging portion 131, which engages within the first latch 711; the second limiting member 14 is provided with a second engaging portion 141, which engages within the second latch 712. By providing the first latch 711 and the second latch 712 corresponding to each other on the first mounting member 71, precise alignment between the latches and the limiting members is ensured, providing a precise positioning interface for the spring structure 10 and avoiding the risk of misalignment during installation. The cooperation between the first engaging portion 131 and the first latch 711 on the first limiting member 13, and the cooperation between the second engaging portion 141 and the second latch 712 on the second limiting member 14, together constitute a stable connection system between the spring structure 10 and the mounting structure 7. The spring structure 10 can be evenly clamped between the first mounting member 71 and the second mounting member 72. The rigid support characteristics of the first mounting member 71 and the second mounting member 72 constrain the spring structure 10 in a fixed position, ensuring that the force applied by the user through the pressing device can be directly transmitted to the spring.
[0036] In this embodiment, the second mounting member 72 is provided with a first through hole 721, and the second baffle 6 is provided with a first protrusion 61. The second baffle 6 abuts against the second mounting member 72, and the first protrusion 61 is placed inside the first through hole 721. A first through cavity 62 is provided inside the first protrusion 61. One end of the shaft 5 passes through the second baffle 6 and the first through cavity 62 and is placed outside the second mounting member 72. Through the tight fit design between the second mounting member 72 and the second baffle 6, the problem of loose installation connection is effectively solved. The first through hole 721 serves as a positioning reference, allowing the first protrusion 61 to be accurately inserted, avoiding the risk of misalignment during installation. The fit between the first protrusion 61 and the first through hole 721 forms a mechanical snap-fit structure, which automatically locks under pressure to prevent lateral displacement. After passing through the second baffle 6 and the first through cavity 62, the shaft 5 extends to the outside of the second mounting member 72, which not only ensures the functional integrity of the shaft 5 but also guarantees the stability of the baffle during movement, avoiding operational difficulties caused by loosening when replacing the spring 3. The design of the second baffle 6 directly abutting against the second mounting part 72 increases the tightness of the contact surface and reduces the gaps caused by vibration or pressure during operation, thereby improving the stability and reliability of the overall structure. In this embodiment, the second mounting component 72 can also be a pressure sensor, which transmits the pressure value of the spring 3 to the terminal, and the user can adjust the force of the spring 3 according to the spring pressure value of the terminal.
[0037] In this embodiment, the mounting structure 7 includes a mounting body, a first mounting member 71, and a second mounting member 72. Both the first mounting member 71 and the second mounting member 72 are rotatably connected to the mounting body. Both the first limiting member 13 and the second limiting member 14 are movably connected to the fixing rod 12, and the first limiting member 13 and the second limiting member 14 can rotate relative to the fixing rod 12. When disassembling the spring structure, when the first pressing member 21 and the second pressing member 22 are pressed, the force is transmitted to the first baffle 4 through the first limiting member 13 and the second limiting member 14, the fixing rod 12, and the fixing seat 11, and then to the spring 3 through the first baffle 4. The spring 3 is compressed, and the first limiting member 13 and the second limiting member 14 are disengaged from the first mounting member 71. The first pressing member 21 and the second pressing member 22 are pressed continuously, and the second mounting member 72 is rotated outward until the spring structure can be removed from the first through hole 721. When external pressure is applied, the first baffle 4 acts as a fixed end to provide positioning, so that the force can be evenly distributed and transmitted through the main structure; while the second baffle 6 is linked with the pressing device and becomes the direct point of force application during operation, thereby realizing the controllable release of the tension of the spring 3.
[0038] In this embodiment, the mounting structure 7 is a pedal, such as an accelerator pedal, a brake pedal, and a clutch pedal.

The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
