Description

Technical Field

[0001] This application relates to the field of metal product protective treatment technology, and in particular to a corrosion-resistant spring structure. Background Technology

[0002] With industrial development, mechanical equipment is being used more and more widely. Especially in extreme environments, improving the service life of parts has become a key focus of the industry, and springs are an important component of mechanical equipment. However, springs are highly susceptible to corrosion in environments with high humidity or abundant chemicals, which can lead to the failure of the entire mechanical system.

[0003] Springs are used to store and release energy in mechanical equipment, control the position of objects, and facilitate the normal operation of machinery. However, existing springs are protected by a protective shell to prevent corrosion from harmful substances such as moisture and salt spray. While the protective shell is protected, it is not restricted. When the spring is compressed or stretched by external forces, the protective shell deforms and moves with the spring, making it easy for the protective shell to move or fall off. This can affect the protective effect on the spring, as well as its service life and stability. Utility Model Content

[0004] The purpose of this application is to address the problem that existing springs, in order to prevent corrosion from harmful substances such as moisture and salt spray, use protective shells to protect the springs and block harmful substances. However, these protective shells are not restricted, and when the spring is compressed or stretched by external forces, the protective shell deforms and moves with the spring, making it easy for the protective shell to move and fall off, thus affecting the protective effect on the spring, its service life, and its stability. This application provides a corrosion-resistant spring structure.

[0005] To achieve the above objectives, this application specifically adopts the following technical solution:

[0006] A corrosion-resistant spring structure includes a spring body with hooks fixed at both ends. A protective shell is fitted onto both the spring body and the hooks. A corrosion-resistant layer is fixed onto the spring body, and a wear-resistant layer is fixed onto the corrosion-resistant layer. The corrosion-resistant layer and the wear-resistant layer are located between the protective shell and the spring body. A limiting mechanism is provided between the spring body and the protective shell.

[0007] By adopting the above technical solution and using a limiting mechanism, the limiting force between the protective shell and the spring is strengthened, reducing the movement and detachment of the protective shell, reducing the impact on the protective effect of the spring, and reducing the impact on the service life and stability of the spring.

[0008] Furthermore, the limiting mechanism includes a limiting sleeve disposed at one end of the hook, the diameter of the limiting sleeve being larger than the diameter of the protective shell, a spring sheet disposed on the protective shell, the spring sheet being circular and distributed in an array, the limiting sleeve being threadedly connected to the spring sheet, the spring sheet being trapezoidal, a rotating column being fixed inside the limiting sleeve, the rotating column being slidably disposed with the end of the hook, and a limiting component being disposed between the protective shell and the limiting sleeve.

[0009] By adopting the above technical solution, the movement of the spring sheet is restricted, causing the spring sheet to bend inward under force, so that multiple spring sheets come into contact with the protective shell, thereby strengthening the restriction force and reducing the movement and detachment of the protective shell.

[0010] Furthermore, the limiting component includes a fixing ring fixed to the protective shell, the fixing ring being fixedly connected to a spring sheet, a limiting block being fixed to one end of the hook, the limiting block extending into the protective shell, and a sealing element being provided between the fixing ring and the limiting sleeve.

[0011] By adopting the above technical solution, the limiting block increases the friction between the protective shell and the spring body, thereby strengthening the restriction between the protective shell and the spring body.

[0012] Furthermore, the sealing element includes a first fixing ring fixed to one end of the limiting sleeve, a second fixing ring fixed to one side of the fixing ring, and a limiting groove adapted to the first fixing ring on the second fixing ring.

[0013] By adopting the above technical solution, the limiting sleeve drives the first fixing ring into the limiting groove, so that the first fixing ring and the second fixing ring fit together, thereby increasing the seal and the protective effect.

[0014] Furthermore, both the first fixing ring and the second fixing ring are elastic rubber rings.

[0015] By adopting the above technical solution, and using both the first and second fixing rings as elastic rubber rings, the sealing effect between the protective shell and the spring body is improved, thereby increasing the protection effect on the spring body.

[0016] Furthermore, the limiting block is an inclined trapezoid, and the protective shell is a polytetrafluoroethylene layer.

[0017] By adopting the above technical solution, the limiting block is an inclined trapezoid, which increases the restriction of the spring body on the protective shell, reducing movement and detachment. The protective shell is a polytetrafluoroethylene layer, which increases the protection effect on the spring body and reduces corrosion.

[0018] Furthermore, the corrosion-resistant layer is a nickel-plated layer.

[0019] By adopting the above technical solution, the corrosion resistance of the spring is increased by using a nickel-plated layer as the corrosion-resistant layer.

[0020] Furthermore, the wear-resistant layer is a chromium-plated layer.

[0021] By adopting the above technical solution, the wear resistance of the spring is increased by using a chromium-plated wear layer.

[0022] In summary, this application includes at least one of the following beneficial effects:

[0023] 1. When using the spring, the operator uses a tool to twist the limiting sleeve, causing it to rotate and move on the spring plate. This causes the spring plate to bend inward under pressure. During movement, the limiting sleeve pulls the fixing ring one into the limiting groove, making the fixing ring one and fixing ring two fit together. This increases the sealing effect between the protective shell and the spring body, enhancing the protection of the spring body. Multiple spring plates contact the protective shell, strengthening the limiting force and reducing the movement and detachment of the protective shell. When the spring is compressed and stretched, the limiting block increases the friction between the protective shell and the spring body, strengthening the restriction between them. This causes the limiting sleeve to contact the end of the hook, increasing the limiting force. Through the limiting mechanism, the limiting force between the protective shell and the spring is strengthened, reducing the movement and detachment of the protective shell, minimizing the impact on the spring's protective effect, service life, and stability.

[0024] 2. When the spring is in use, the inclined trapezoidal restraint block increases the restriction of the spring body on the protective shell, reducing movement and detachment. The polytetrafluoroethylene layer of the protective shell increases the protection of the spring body. The nickel-plated corrosion-resistant layer increases the spring's corrosion resistance. The chromium-plated wear-resistant layer increases the spring's wear resistance, which helps to improve the spring's service life and stability. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0032] This application discloses a corrosion-resistant spring structure.

[0033] Reference Figures 1-3 A corrosion-resistant spring structure includes a spring body 1, hooks 5 fixed at both ends of the spring body 1, a protective shell 2 fitted on both the spring body 1 and the hooks 5, a corrosion-resistant layer 3 fixed on the spring body 1, a wear-resistant layer 4 fixed on the corrosion-resistant layer 3, the corrosion-resistant layer 3 and the wear-resistant layer 4 being located between the protective shell 2 and the spring body 1, and a limiting mechanism being provided between the spring body 1 and the protective shell 2.

[0034] When using the spring, the staff can easily install the spring into the appropriate position using the hooks 5 at both ends of the spring body 1. During use, the protective shell 2 protects the spring body 1, preventing the corrosion of harmful substances. The limiting mechanism strengthens the limiting force between the protective shell 2 and the spring, reducing the movement and detachment of the protective shell 2, reducing the impact on the protective effect of the spring, and reducing the impact on the service life and stability of the spring.

[0035] Reference Figures 2-4 The limiting mechanism includes a limiting sleeve 8 at one end of the hook 5, the diameter of which is larger than the diameter of the protective shell 2. A spring plate 10, circular in shape and arranged in an array, is mounted on the protective shell 2. The limiting sleeve 8 is threadedly connected to the spring plate 10, which is trapezoidal. A rotating column 7 is fixed inside the limiting sleeve 8 and slidably mounted to the end of the hook 5. A limiting component is provided between the protective shell 2 and the limiting sleeve 8. The limiting component includes a fixing ring 9 fixed to the protective shell 2, which is fixedly connected to the spring plate 10. A limiting block 6 is fixed to one end of the hook 5, extending into the protective shell 2. A sealing element is provided between the fixing ring 9 and the limiting sleeve 8. The sealing element includes a first fixing ring 11 fixed to one end of the limiting sleeve 8, and a second fixing ring 12 fixed to one side of the fixing ring 9. The second fixing ring 12 has a limiting groove adapted to the first fixing ring 11. Both the first fixing ring 11 and the second fixing ring 12 are elastic rubber rings.

[0036] When using the spring, the operator uses a tool to twist the limiting sleeve 8, causing it to rotate and move on the spring plate 10. This causes the spring plate 10 to bend inward under pressure. During this movement, the limiting sleeve 8 pulls the fixing ring 11 into the limiting groove, allowing the fixing ring 11 and fixing ring 12 to fit together, increasing the seal. Since both fixing ring 11 and fixing ring 12 are elastic rubber rings, they enhance the sealing effect between the protective shell 2 and the spring body 1, increasing the protection of the spring body 1. This also causes multiple spring plates 10 to contact the protective shell 2, strengthening the seal. The limiting force reduces the movement and detachment of the protective shell 2. When the spring is compressed and stretched, the limiting block 6 increases the friction between the protective shell 2 and the spring body 1, strengthens the restriction between the protective shell 2 and the spring body 1, and makes the limiting sleeve 8 abut against the end of the hook 5, increasing the limiting force. The fixed ring 9, spring plate 10 and limiting sleeve 8 reduce the movement and detachment of the protective shell 2. Through the limiting mechanism, the limiting force between the protective shell 2 and the spring is strengthened, reducing the movement and detachment of the protective shell 2, reducing the impact on the protective effect of the spring, and reducing the impact on the service life and stability of the spring.

[0037] Reference Figure 2 and Figure 3 The limiting block 6 is an inclined trapezoid, and the protective shell 2 is a polytetrafluoroethylene layer. The corrosion-resistant layer 3 is a nickel-plated layer. The wear-resistant layer 4 is a chromium-plated layer.

[0038] When the spring is in use, the inclined trapezoidal shape of the limiting block 6 increases the restriction of the spring body 1 on the protective shell 2, reducing movement and detachment. The polytetrafluoroethylene layer of the protective shell 2 increases the protection effect on the spring body 1. The nickel-plated layer of the corrosion-resistant layer 3 increases the corrosion resistance of the spring. The chromium-plated layer of the wear-resistant layer 4 increases the wear resistance of the spring, which helps to improve the service life and stability of the spring.

[0039] The implementation principle of the corrosion-resistant spring structure in this embodiment is as follows: when the spring is in use, the staff can easily install the spring into a suitable position through the hooks 5 at both ends of the spring body 1. When in use, the spring body 1 is protected by the protective shell 2.

[0040] When the spring is in use, the operator uses a tool to twist the limiting sleeve 8, causing the limiting sleeve 8 to rotate and move on the spring plate 10. This causes the spring plate 10 to bend inward under pressure. During the movement, the limiting sleeve 8 drives the fixing ring 11 into the limiting groove, so that the fixing ring 11 and the fixing ring 2 12 fit together, increasing the seal. Since both the fixing ring 11 and the fixing ring 2 12 are elastic rubber rings, it is easy to increase the sealing effect between the protective shell 2 and the spring body 1, and increase the protection effect of the spring body 1. This causes multiple spring plates 10 to abut against the protective shell 2, strengthening the limiting force and reducing the movement and detachment of the protective shell 2. When the spring is compressed and stretched, the limiting block 6 increases the friction between the protective shell 2 and the spring body 1, strengthening the restriction between the protective shell 2 and the spring body 1. This causes the limiting sleeve 8 to abut against the end of the hook 5, increasing the limiting force.

[0041] When the spring is in use, the limiting block 6 is an inclined trapezoid, which increases the restriction of the spring body 1 on the protective shell 2, reducing movement and detachment. The protective shell 2 is a polytetrafluoroethylene layer, which increases the protection effect on the spring body 1. The corrosion-resistant layer 3 is a nickel-plated layer, which increases the corrosion resistance of the spring. The wear-resistant layer 4 is a chromium-plated layer, which increases the wear resistance of the spring.
