Description

Technical Field

[0001] This utility model relates to the field of spring technology, specifically a high-temperature resistant rectangular spring. Background Technology

[0002] A rectangular spring is an elastic element made of steel wire with a non-circular cross section (usually rectangular). Compared with traditional circular cross section springs, its design achieves high load-bearing capacity, low height, and high space utilization through geometric optimization. Currently, most high-temperature resistant rectangular springs use nickel-based alloys such as Inconel 718 and Hastelloy X or 310S stainless steel as the base material, and add elements such as tungsten and molybdenum to improve high-temperature strength.

[0003] Existing high-temperature resistant springs, such as the high-toughness high-temperature resistant spring disclosed in publication number CN217682975U, have the advantages of preventing the main body from tilting and guiding the main body. However, after installation, it is inconvenient to insulate and dissipate heat at the upper and lower ends and the inner and outer contact parts, which makes its high-temperature resistance performance poor. Therefore, we propose a high-temperature resistant rectangular spring. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A high-temperature resistant rectangular spring includes: a spring body and a heat insulation and heat dissipation assembly; the heat insulation and heat dissipation assembly includes an upper heat insulation seat and a lower heat insulation seat movably installed at the upper and lower ends of the spring body, an upper heat insulation inner cylinder fixedly installed at the lower part of the upper heat insulation seat, a lower heat insulation inner cylinder fixedly installed at the upper part of the lower heat insulation seat, and an upper heat dissipation plate and a lower heat dissipation plate fixedly installed on both sides of the upper heat insulation seat and both sides of the lower heat insulation seat, respectively.

[0007] Preferably, heat dissipation fins are also fixedly arranged at the outer ends of both the upper and lower heat dissipation plates.

[0008] Preferably, the bottom of the upper insulated inner cylinder is also provided with a plurality of upper restraint strips.

[0009] Preferably, the top of the lower heat-insulating inner cylinder is also provided with a plurality of lower restraining strips, and each of the lower restraining strips is provided with a groove in the middle, and the groove matches the upper restraining strip.

[0010] Preferably, both the upper and lower heat insulation seats are provided with recesses, and the upper and lower ends of the spring body are movably installed in the recesses.

[0011] Preferably, both the upper and lower heat sinks have an inner bevel at one end.

[0012] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0013] 1. In this utility model, the upper and lower heat insulation seats installed at the upper and lower ends of the spring body, together with the upper and lower heat insulation inner cylinders installed at their inner ends inside the spring body, can prevent the spring body from directly contacting the upper and lower end components and the inner components after installation, thereby preventing the heat from the upper and lower end components and the inner components from being conducted to the spring body after installation. At the same time, the upper and lower heat dissipation plates installed at the outer ends of the upper and lower heat insulation seats, as well as the heat dissipation fins arranged on the outer sides of the upper and lower heat dissipation plates, can also uniformly transfer and dissipate heat in the spring body from the upper and lower ends. Thus, by using the heat insulation and heat dissipation structure of the spring body during use, the high temperature resistance of this rectangular spring can be enhanced.

[0014] 2. In this utility model, the upper binding strip, which is installed at the bottom of the upper heat insulation inner cylinder and inserted into the lower binding strip at the top of the lower heat insulation inner cylinder, can bind the position between the upper and lower heat insulation seats at the upper and lower ends of the spring body, thereby ensuring the uniform arrangement of the upper heat dissipation plate and the lower heat dissipation plate on the outer side of the upper and lower heat insulation seats, ensuring uniform heat dissipation and avoiding collisions between them.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0023] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a high-temperature resistant rectangular spring.

[0024] Example 1:

[0025] Combination Figure 1-4 As shown, this utility model provides a high-temperature resistant rectangular spring, comprising: a spring body 100 and a heat insulation and heat dissipation assembly 200; the heat insulation and heat dissipation assembly 200 includes an upper heat insulation seat 201 and a lower heat insulation seat 202 movably mounted on the upper and lower ends of the spring body 100, an upper heat insulation inner cylinder 203 fixedly mounted on the lower part of the upper heat insulation seat 201, a lower heat insulation inner cylinder 204 fixedly mounted on the upper part of the lower heat insulation seat 202, and an upper heat dissipation plate 205 and a lower heat dissipation plate 206 fixedly mounted on both sides of the upper heat insulation seat 201 and both sides of the lower heat insulation seat 202, respectively; the outer ends of the upper heat dissipation plate 205 and the lower heat dissipation plate 206 are further... Heat dissipation fins 207 are arranged and fixedly installed. Multiple sets of upper binding strips 208 are also arranged and fixedly installed at the bottom of the upper heat insulation inner cylinder 203. Multiple sets of lower binding strips 209 are also arranged and fixedly installed at the top of the lower heat insulation inner cylinder 204. The lower binding strips 209 are all provided with slots 210 in the middle, and the slots 210 match the upper binding strips 208. The upper heat insulation seat 201 and the lower heat insulation seat 202 are also provided with recesses 211, and the upper and lower ends of the spring body 100 are movably installed in the recesses 211. The upper heat dissipation plate 205 and the lower heat dissipation plate 206 are also provided with an inner bevel 212 at one end.

[0026] Specifically, a rectangular spring is an elastic element made of steel wire with a non-circular cross-section (usually rectangular). Currently, most high-temperature resistant rectangular springs use Inconel 718 and Hastelloy. Using nickel-based alloys such as X or 310S stainless steel as the base material, the high-temperature resistance of the body is improved by adding elements such as tungsten and molybdenum. The upper heat insulation seat 201 and lower heat insulation seat 202 installed at the upper and lower ends of the spring body 100, together with the upper heat insulation inner cylinder 203 and lower heat insulation inner cylinder 204 installed inside the spring body 100, can prevent the spring body 100 from directly contacting the upper and lower end components and the inner components after installation, thereby preventing the heat from the upper and lower end components and the inner components from being conducted to the spring body 100 after installation. At the same time, the upper heat dissipation plate 205 and lower heat dissipation plate 206 installed at the outer ends of the upper heat insulation seat 201 and lower heat insulation seat 202, as well as the heat dissipation fins 207 arranged on the outer side of the upper heat dissipation plate 205 and lower heat dissipation plate 206, can also uniformly transfer and dissipate heat in the spring body 100 from the upper and lower ends. Thus, by using the heat insulation and heat dissipation structure of the spring body 100 during use, the high-temperature resistance of this rectangular spring is enhanced. The upper heat insulation inner cylinder 203 is arranged at the bottom. The upper binding strip 208, inserted into the lower binding strip 209 at the top of the lower heat insulation inner cylinder 204, can bind the position between the upper heat insulation seat 201 and the lower heat insulation seat 202 at the upper and lower ends of the spring body 100. This ensures the uniform arrangement of the upper heat dissipation plate 205 and the lower heat dissipation plate 206 on the outer sides of the upper heat insulation seat 201 and the lower heat insulation seat 202, ensuring uniform heat dissipation and preventing collisions. Simultaneously, the upper heat insulation seat 201 and the lower heat insulation seat 202 at the upper and lower ends of the spring body 100 facilitate convenient installation. In case of damage, it can be easily disassembled for repair or replacement. The notch 211 in the lower restraint strip 209 is mainly used for matching and installing the upper restraint strip 208. The notches 211 in the upper heat insulation seat 201 and the lower heat insulation seat 202 are mainly used for installing the upper and lower ends of the spring body 100. The inner bevel 212 at one end of the upper heat dissipation plate 205 and the lower heat dissipation plate 206 is mainly used to prevent the upper heat dissipation plate 205 and the lower heat dissipation plate 206 from being squeezed and deformed during the extension and retraction of the spring body 100.

[0027] Working principle and usage process of this utility model:

[0028] When the spring body 100 is in use, the upper heat insulation seat 201 and lower heat insulation seat 202 installed at its upper and lower ends can prevent the spring body 100 from directly contacting the upper and lower end components during use. The upper heat insulation inner cylinder 203 and lower heat insulation inner cylinder 204 sleeved on the upper heat insulation seat 201 and lower heat insulation seat 202 and extending to the inner end of the spring body 100 can also prevent the inner side of the spring body 100 from directly contacting the middle component. Thus, through the heat insulation of the upper and lower ends and the inner end of the spring body 100, the heat conduction of the spring body 100 by external components during use is prevented. The heat generated inside the spring body 100 during use can also be evenly transferred to the outside through the upper heat dissipation plate 205 and lower heat dissipation plate 206 on the upper and lower sides of its outer end, as well as the heat dissipation fins 207 arranged on the outer side of the upper heat dissipation plate 205 and lower heat dissipation plate 206, thereby improving the heat dissipation effect of the spring body 100 during use.

[0029] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
