Technical Field

[0001] The utility model belongs to the technical field of fasteners, and particularly relates to a mushroom fastener for high-temperature environments. Background Technique

[0002] The clamping parts of existing fasteners are usually made of plastic materials. However, due to the insufficient hardness and heat resistance of plastic materials, they are prone to fracture or deformation in high and low temperature environments, with a short service life and unable to meet the working requirements, which limits their application scope in large-scale industrial applications.

[0003] The above information disclosed in the background technique part is only used to enhance the understanding of the background technique of the technology described in this article. Therefore, the background technique may contain certain information that is not prior art known to those skilled in the art in this country. Summary of the Utility Model

[0005] The technical solution adopted by the utility model is as follows:

[0006] A mushroom fastener for high-temperature environments is composed of a male fastener and a female fastener that cooperate with each other. The structures of the male fastener and the female fastener are the same, and both include a base and a mushroom fastener surface provided on the base.

The mushroom fastener surface includes a plurality of clamping parts fixed on the base, and the clamping parts are made of TC4 titanium alloy structural parts.

[0007] A high-temperature resistant anti-corrosion coating is further provided on the surface of the clamping part.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Apparently, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Usually, the components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the detailed description of the embodiments of the present application provided in the drawings below is not intended to limit the scope of the present application that is required to be protected, but only represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0023] Embodiment 1

[0024] This embodiment provides a mushroom buckle for high-temperature environments. Refer to Figures 1 - 3 :

[0025] This mushroom buckle is composed of a male buckle 1 and a female buckle 2 that cooperate with each other. The structures of the two are the same and both include the following main parts:

[0026] Base 3: The base 3 is integrally machined from TC4 titanium alloy, which has excellent mechanical strength and corrosion resistance, ensuring structural stability in harsh environments.

[0027] Mushroom buckle surface 4: The mushroom buckle surface 4 is fixed on the base 3 and is designed as a plurality of evenly distributed raised parts to facilitate the engagement between the male buckle 1 and the female buckle 2, realizing the connection or disassembly of the male and female buckles 2. This design not only increases the contact area but also improves the connection stability.

[0028] In a specific embodiment, the mushroom buckle surface 4 includes a number of clamping parts 5 fixed on the base 3. The clamping parts 5 are made of TC4 titanium alloy structural parts and are integrally machined using wire cutting technology. The TC4 titanium alloy material itself has a certain degree of softness and toughness, and is resistant to high temperature and corrosion, with a melting point as high as 1600 °C, capable of working stably for a long time in high-temperature environments, avoiding the defect of plastic materials deforming due to thermal expansion.

[0029] It should be understood that since the metal buckle in the present utility model uses TC4 titanium alloy material to make the clamping parts 5, it can play a greater role in high and low temperature, acid-base and corrosive environments, with simple operation, good reliability and stability. At the same time, its hardness and heat resistance are better than those of plastic buckles, and it can meet the working requirements under special environmental conditions.

[0030] As a preferred embodiment, a high-temperature resistant anti-corrosion coating is also provided on the surface of the clamping part 5. Further, the high-temperature and corrosion-resistant performance of the clamping part 5 can be improved.

[0031] Furthermore, the anti-corrosion coating is one of a ceramic coating, a polymer coating, a metal coating, and a silicate coating.

[0032] The ceramic coating has the characteristics of high temperature resistance, corrosion resistance, and high hardness, and is commonly used in fields such as aerospace and automotive. Preferably, an alumina (Al 2 O 3 ) coating or a silicon nitride (Si 3 N 4 ) coating is used.

[0033] The polymer coating is selected from polyimide (PI) coating or polyetheretherketone (PEEK) coating, wherein the polyimide coating can withstand high temperatures up to 260°C, and the polyetheretherketone coating can withstand high temperatures up to 300°C.

[0034] The metal coating is aluminum coating or nickel coating. Both have good high temperature resistance and oxidation resistance. The nickel coating is high temperature resistant (up to 700°C).

[0035] The silicate coating can withstand high temperatures up to 1200°C and also has good corrosion resistance.

[0036] Example 2

[0037] Further embodiments of the clamping member 5 are provided, see Figure 4 The clamping member 5 includes a column 501 and a mushroom head 502. One end of the column 501 is fixed to the base 3, and the mushroom head 502 is fixed to the other end of the column 501. The column 501 is an elastically deformable structure. The base 3, the column 501 and the mushroom head 502 are an integrally formed structure. When the upper and lower mushroom buckles are buckled by external force, they can be easily inserted into each other and form a firm buckling state in the vertical, left and right directions; when unlocked, the buckling state can be released by tearing the edges in all directions for multiple uses.

[0038] As a preferred embodiment, a rounded structure 503 is provided at the edge of the mushroom head 502 to prevent the formation of a sharp angle structure at the edge, so that the mushroom head 502 has a smooth and round structure and is safer.

[0039] As a preferred embodiment, if the angle between the column 501 and the plane of the base 3 is less than 90 degrees, the locking structure is not easy to tear apart, and the angle between the column 501 and the plane of the base 3 is greater than or equal to 90 degrees. When the angle is greater than 90 degrees, the column 501 is a conical column. The conical structure can prevent the column 501 from collapsing, which is equivalent to strengthening the root, making its bonding structure more stable. At the same time, the top occupies less space, freeing up space for the mushroom head 502 structure to lock together. When the angle is 90 degrees, the column 501 is a prism, which is easy to manufacture and easy to tear apart when the two buckles are torn apart.

[0040] As described above, the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
