Description

Technical Field

[0001] The utility model relates to the technical field of medal anti-oxidation, in particular to an anti-oxidation metal medal. Background Art

[0002] Metal medals, as eternal symbols of honor and commemoration, their preservation methods are directly related to the inheritance and preservation of their value. However, in the daily storage process, people often ignore the correct preservation method. Metal medals are exposed to the air for a long time, especially in a humid environment, and they are easy to react chemically with oxygen and moisture in the air, which in turn causes oxidation. This oxidation reaction will not only cause rust on the surface of the medal and make the color dull, but in severe cases it may even affect the overall structure of the medal, causing it to suffer irreversible damage. Such damage not only greatly reduces the beauty of the medal, but is also likely to weaken the historical and cultural value behind it.

[0003] Some medals are designed with a pedestal. These pedestals have a good decorative effect when displaying the medals and can also provide a certain degree of protection for the medals when stored. When the pedestal is closed, it can reduce the entry of outside air and moisture into the pedestal, thereby reducing the risk of oxidation of the medals. However, although some pedestals on the market can isolate some moisture and air from the outside, there may still be a certain amount of air and moisture inside the pedestal. These residual air and moisture may still cause oxidation of the medals over a long period of time.

[0004] Chinese patent document CN217161246U discloses a copper medal that is convenient to hang, including a medal body, the inner layer of the medal body is made of copper, the outer side of the inner layer of the medal body is wrapped with an insulating layer, and the outer side of the insulating layer is wrapped with a protective film; however, there are still the following defects in the implementation process:

[0005] Although the medals in the above-mentioned documents can play an anti-oxidation role through the protective film, preventing the medal body from developing verdigris in humid air and affecting the appearance of the medal body, during long-term storage, the protective film may fail due to factors such as aging, wear or chemical reaction, thereby affecting its protective effect and then causing the medal to oxidize. Utility Model Content

[0006] The purpose of the utility model is to provide an anti-oxidation metal medal to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0008] The anti-oxidation metal medal comprises a base assembly; an outer block is placed on the upper part of the base assembly, an inner block is fixedly connected to the inner cavity of the outer block, a protective cover is symmetrically rotatably connected to the upper end of the base assembly, a slide rail is symmetrically fixedly connected to the upper part of the inner cavity of the protective cover, a placement box assembly is slidably connected to the inner cavities of two slide rails on the same side, and a desiccant is placed in the inner cavity of the placement box assembly.

[0009] A further improvement of the technical solution of the utility model is that: a support block is symmetrically fixedly connected to the upper end of the base component, a placement groove is opened in the middle of the upper end of the base component, and a water outlet hole is symmetrically opened in the inner cavity of the placement groove.

[0010] The above technical solution is adopted. In this solution, a support block is fixedly connected to the upper end of the base assembly, so that the support block can be used to support the outer block. A placement groove is provided, so that the placement groove can be used to limit the outer block, which is convenient for displaying and storing medals. When the medals are stored, both sides of the medals can be repeatedly in contact with the air, reducing the accumulation of moisture on the surface of the medal, which may cause the medal to oxidize.

[0011] The further improvement of the technical solution of the utility model is that the end surface of the inner block is inclined, the middle part of the end surface of the inner block is convex, and the edges of the end surface of the inner block are all rounded.

[0012] By adopting the above technical solution, the end face of the inner block is set at an angle, so that the liquid accumulated on the surface of the inner block, such as sweat from the hands, can quickly flow from the surface of the inner block toward the outer block, thereby reducing the time the liquid stays on the surface of the inner block.

[0013] The further improvement of the technical solution of the utility model is that the end faces of the outer block are all rounded, two water outlet holes are symmetrically opened at the lower part of the outer block, and the inner cavity of the second water outlet hole on the same side is communicated with the inner cavity of the first water outlet hole.

[0014] The above technical solution is adopted, in which a water outlet hole 2 is opened at the lower part of the outer block, and then the inner cavity of the water outlet hole 2 is communicated with the inner cavity of the water outlet hole 1, so that the liquid flowing to the outer block can be quickly discharged through the cooperation of the water outlet hole 2 and the water outlet hole 1, thereby reducing the residence time of the liquid on the medal and reducing the risk of oxidation.

[0015] A further improvement of the technical solution of the utility model is that a drainage groove is symmetrically provided on one side of the outer block close to the inner block.

[0016] The above technical solution is adopted, in which a drainage groove is opened on the side of the outer block close to the inner block, so that the liquid accumulated on the surface of the inner block and the outer block can quickly flow toward the inner cavity of the drainage groove, thereby reducing the residence time of the liquid on the surface of the inner block and the outer block, and keeping the surface of the inner block and the outer block dry, thereby reducing the risk of oxidation.

[0017] A further improvement of the technical solution of the utility model is that both the inner block surface and the outer block surface are coated with an anti-oxidation coating.

[0018] The above technical solution is adopted, in which a coating made of aluminum oxide material is applied on the surface of the inner block and the surface of the outer block, thereby effectively isolating the air and moisture, preventing the medal from coming into contact with oxygen and undergoing an oxidation reaction, and the coating can still maintain good anti-oxidation properties in harsh environments such as high temperature and high humidity, ensuring that the medal will not develop oxidation spots or discoloration during long-term use.

[0019] A further improvement of the technical solution of the utility model is that the placement box assembly includes a shell, the upper end of the shell is symmetrically fixedly connected with a slider, the slider on the same side is slidably connected to the inner cavity of the slide rail, and the middle part of the lower end of the shell is provided with a plurality of air inlet holes that penetrate the lower end of the shell and extend to the inner cavity of the shell.

[0020] The above technical solution is adopted, in which a slider is fixedly connected to the upper end of the shell, so that the position of the slider can be limited by the slide rail, and a plurality of air inlet holes are opened to facilitate moisture in the inner cavity of the protective cover to enter the inner cavity of the shell through the inner cavity of the air inlet holes, and then the moisture is absorbed by the desiccant in the inner cavity of the shell, so that the moisture content in the inner cavity of the protective cover can be reduced, and then when the medal is stored for a long time, the medal can be prevented from contacting with moisture, which may cause oxidation of the medal.

[0021] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0022] 1. The utility model provides an anti-oxidation metal medal, which can support and connect the outer block through the base assembly, so that the surfaces of the inner block and the outer block can be fully in contact with the air, thereby preventing a large amount of moisture from accumulating on the surfaces of the inner block and the outer block; the base assembly is rotatably connected to the protective cover, so that when the medal is displayed, it can be decorated with the protective cover; when the medal is stored, the medal can be protected by the protective cover to prevent the outside air and moisture from contacting the medal; a placement box assembly is slidably connected to the inner cavity of the protective cover, so that the placement box assembly can be separated from the protective cover, and then the desiccant in the inner cavity of the placement box assembly can be replaced easily; a desiccant is placed in the inner cavity of the placement box assembly, so that the desiccant can be used to absorb moisture and water in the inner cavity of the protective cover, thereby reducing the moisture in the inner cavity of the protective cover from contacting the medal, thereby reducing or even preventing the medal from oxidizing.

DETAILED DESCRIPTION

[0035] The present invention is further described in detail below in conjunction with the embodiments:

[0036] Example 1

[0037] like Figure 1-9As shown, the utility model provides an anti-oxidation metal medal, including a base assembly 1; an outer block 3 is placed on the upper part of the base assembly 1, and an inner block 2 is fixedly connected to the inner cavity of the outer block 3; a protective cover 4 is symmetrically rotatably connected to the upper end of the base assembly 1, and a slide rail 41 is symmetrically fixedly connected to the upper part of the inner cavity of the protective cover 4, and a placement box assembly 5 is slidably connected to the inner cavity of the two slide rails 41 on the same side, and a desiccant is placed in the inner cavity of the placement box assembly 5.

[0038] In the present embodiment, the base assembly 1 is provided so that the medal can be supported and connected when it is displayed, and the protective cover 4 can serve as a decoration for the medal when it is displayed, and can protect and isolate the medal when it is stored, thereby reducing the entry of external air and moisture into the inner cavity of the protective cover 4 and then reacting with the medal to cause oxidation of the medal. The placement box assembly 5 is slidably connected to the protective cover 4, thereby facilitating the replacement of the desiccant in the inner cavity of the placement box assembly 5, and the desiccant in the inner cavity of the placement box assembly 5 can absorb the moisture in the inner cavity of the protective cover 4, thereby preventing the inner cavity of the protective cover 4 from containing a large amount of moisture, which causes the moisture in the moisture to react with the medal and then cause oxidation of the medal.

[0039] Example 2

[0040] like Figure 5-8 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, a support block 11 is symmetrically fixedly connected to the upper end of the base assembly 1, a placement groove 12 is opened in the middle of the upper end of the base assembly 1, and a water outlet hole 13 is symmetrically opened in the inner cavity of the placement groove 12, the end face of the inner block 2 is inclined, the middle part of the end face of the inner block 2 is convex, the edges of the end face of the inner block 2 are all rounded, the end faces of the outer block 3 are all rounded, and water outlet holes 31 are symmetrically opened in the lower part of the outer block 3, and the inner cavity of the water outlet hole 2 31 on the same side is connected with the inner cavity of the water outlet hole 13, and a drainage groove 6 is symmetrically opened on the side of the outer block 3 close to the inner block 2, and the surfaces of the inner block 2 and the outer block 3 are coated with an anti-oxidation coating.

[0041] In this embodiment, when the medal is to be displayed, some visitors may pick up the medal and watch it at a close distance. Since human hands are prone to sweating, when visitors pick up the medal to watch it, sweat will be left on the surface of the medal. Then, after the visitors reset the medal, some liquid will remain on the medal. Although the surface of the medal is coated with a coating made of aluminum oxide material, which can effectively isolate air and moisture and prevent the medal from contacting with oxygen to cause oxidation reaction, a large amount of liquid remains on the surface of the medal, which will cause some corrosion to the surface of the medal. Therefore, a drainage groove 6 is provided in a layer of the outer block 3 close to the inner block 2, so that the residual liquid will flow from the surface of the inner block 2 and the surface of the outer block 3 toward the direction of the drainage groove 6, and then the liquid flowing into the inner cavity of the drainage groove 6 will flow into the inner cavity of the second water outlet hole 31. Since the inner cavity of the second water outlet hole 31 is connected with the inner cavity of the first water outlet hole 13, the liquid flowing into the inner cavity of the second water outlet hole 31 will be discharged from the inner cavity of the first water outlet hole 13, thereby reducing the time that the residual liquid stays on the surface of the medal.

[0042] Example 3

[0043] like Figure 2 , Figure 3 , Figure 4 , Fig. 9 As shown, based on Example 2, the utility model provides a technical solution: preferably, the placement box assembly 5 includes a shell 51, and a slider 52 is symmetrically fixedly connected to the upper end of the shell 51, and the slider 52 on the same side is slidably connected to the inner cavity of the slide rail 41, and a plurality of air inlet holes 53 are opened in the middle of the lower end of the shell 51 and extend through the lower end of the shell 51 to the inner cavity of the shell 51.

[0044] In this embodiment, when the medal needs to be stored for a long time, the two protective covers 4 are closed by rotating the protective cover 4, so that the outside air and moisture entering the inner cavity of the protective cover 4 can be reduced. Then, since a desiccant is placed in the inner cavity of the shell 51, the air and moisture in the inner cavity of the protective cover 4 will flow into the inner cavity of the shell 51 through the plurality of air inlet holes 53. Then, the desiccant in the inner cavity of the shell 51 can absorb the moisture in the inner cavity of the protective cover 4, thereby reducing the moisture content of the air in the inner cavity of the protective cover 4, thereby reducing A large amount of water vapor accumulates on the surface of the medal, which then causes oxidation and rusting of the medal. The desiccant is used to absorb the moisture in the inner cavity of the protective cover 4, so that the inner cavity of the protective cover 4 can be kept dry, thereby improving the anti-oxidation ability of the medal. When the desiccant in the inner cavity of the placement box assembly 5 absorbs a certain amount of moisture and needs to be replaced, the protective cover 4 can be flipped open, and then the placement box assembly 5 can be slid apart from the protective cover 4, and then the desiccant in the inner cavity of the outer shell 51 can be replaced, and then the protective cover 4 and the placement box assembly 5 can be flipped and reset.

[0045] The following is a detailed description of the working principle of the anti-oxidation metal medal.

[0046] like Figure 1-9 As shown, when the medal is to be displayed, some visitors may pick up the medal and watch it at a close distance. Since human hands are prone to sweating, when visitors pick up the medal to watch it, sweat will be left on the surface of the medal. Then, after the visitors reset the medal, some liquid will remain on the medal. Although the surface of the medal is coated with a coating made of aluminum oxide material, which can effectively isolate air and moisture and prevent the medal from contacting with oxygen and causing oxidation reaction, a large amount of liquid remains on the surface of the medal, which will cause a little corrosion to the surface of the medal. Therefore, a drainage groove 6 is provided in a layer of the outer block 3 close to the inner block 2, so that the residual liquid will flow from the surface of the inner block 2 and the surface of the outer block 3 toward the direction of the drainage groove 6, and then the liquid flowing into the inner cavity of the drainage groove 6 will flow into the inner cavity of the second water outlet hole 31. Since the inner cavity of the second water outlet hole 31 is connected with the inner cavity of the first water outlet hole 13, the liquid flowing into the inner cavity of the second water outlet hole 31 will be discharged from the inner cavity of the first water outlet hole 13, thereby reducing the time that the residual liquid stays on the surface of the medal;

[0047] When the medal needs to be stored for a long time, the two protective covers 4 are closed by rotating the protective cover 4, so as to reduce the external air and moisture entering the inner cavity of the protective cover 4. Then, since a desiccant is placed in the inner cavity of the shell 51, the air and moisture in the inner cavity of the protective cover 4 will flow into the inner cavity of the shell 51 through a plurality of air inlet holes 53. Then, the desiccant in the inner cavity of the shell 51 can be used to absorb the moisture in the inner cavity of the protective cover 4, so as to reduce the moisture content of the air in the inner cavity of the protective cover 4, thereby reducing the accumulation of a large amount of water vapor on the surface of the medal, and then causing oxidation and rusting of the medal. The desiccant is used to absorb the moisture in the inner cavity of the protective cover 4, so as to keep the inner cavity of the protective cover 4 dry and improve the anti-oxidation ability of the medal. When the desiccant in the inner cavity of the placement box assembly 5 absorbs a certain amount of moisture and needs to be replaced, the protective cover 4 can be flipped open, and then the placement box assembly 5 is slid and separated from the protective cover 4, and then the desiccant in the inner cavity of the shell 51 is replaced, and then the protective cover 4 and the placement box assembly 5 are flipped and reset.

[0048] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
