Description

Technical Field

[0001] This utility model relates to the field of magnesium-aluminum alloy bayonet technology, and in particular to magnesium-aluminum alloy bayonet based on basic subsurface oxidation technology. Background Technology

[0002] In cosmetic packaging, the bottle cap structure needs to balance sealing, ease of operation, and corrosion resistance. Traditional caps are mostly made of plastic or ordinary metal. However, in long-term use, cosmetic ingredients (such as acids, alkalis, and alcohols) can easily corrode the cap metal. Therefore, caps made of magnesium-aluminum alloy are now available on the market.

[0003] However, this buckle shares the same problem as traditional buckles: the cover must be completely removed before the pump head can be pressed, and the cover is easily lost. To solve this problem, this invention proposes a magnesium-aluminum alloy buckle based on basic subsurface oxidation technology. This technology forms a dense oxide film, significantly improving resistance to corrosion from cosmetic ingredients. The buckle mechanism allows the cover to be pressed without removal, avoiding the risk of loss. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where the card cover is easily lost, and to propose a magnesium-aluminum alloy card based on basic subsurface oxidation technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A magnesium-aluminum alloy bayonet based on basic subsurface oxidation technology includes a fixing ring and a cover. The cover includes a cap and a ring. The ring is located on the outer wall of the fixing ring. An inner groove is formed on the inner wall of the ring. An inner sliding ring is slidably arranged inside the inner groove, and the inner sliding ring is fixedly arranged at the bottom of the cap.

[0007] A snap-fit ​​mechanism is used to engage a snap ring and a fixed ring. The snap-fit ​​mechanism is disposed inside the snap ring and includes at least one slider. The outer wall of the snap ring has at least one side sliding groove. The slider is slidably disposed inside the side sliding groove. An insert plate is fixedly disposed on one side of the slider. The outer wall of the fixed ring has at least one snap groove. One end of the insert plate slides through the snap ring and engages with the snap groove.

[0008] In one possible design, limit grooves are provided on both sides of the slider, and limit plates are fixedly provided on the inner walls of both sides of the side sliding groove. The two limit plates are located inside the two limit grooves respectively, and the same compression spring is fixedly provided between the inner wall of one side of the limit groove and the limit plate on the same side.

[0009] In one possible design, the bottom of the insert plate is set as a slope.

[0010] In one possible design, the buckling mechanism further includes a rotating bar, the outer wall of the retaining ring has a connecting groove, and the bottom end of the connecting groove is connected to the top of the side sliding groove. The rotating bar is located inside the connecting groove, and the bottom end of the rotating bar is rotatably mounted on the top of the slider. The outer wall of the retaining cap has a notch, and the top end of the rotating bar is located inside the notch.

[0011] In one possible design, the outer wall of the cap has a through hole.

[0012] In one possible design, the top of the outer wall of the cap is fixedly provided with an extension edge, and the extension edge is located above the through hole.

[0013] In this application, during actual use, the retaining ring is first fastened to the outer wall of the fixing ring. At this time, the inclined surface of the insert plate will touch the top of the fixing ring, causing the insert plate and the slider to move. When the insert plate is located on one side of the slot, the slider will be reset by the force of the compression spring, thereby driving the insert plate to reset, so that the insert plate passes through the retaining ring and is locked into the inside of the slot, thereby realizing the connection and installation between the cover and the fixing ring.

[0014] When it is necessary to release the limiting position between the cap and the ring in the cover, simply rotate the rotating bar so that one end of the rotating bar is disengaged from the inside of the notch. At this time, the cap will lose its limiting constraint and can be pressed down. When it is necessary to release the engagement between the cover and the fixing ring, the rotating bar can also be rotated out and the slider can be moved by pulling the rotating bar to release the buckle between the fixing ring and the cover.

[0015] In this utility model, the magnesium-aluminum alloy bayonet based on basic subsurface oxidation technology, through a buckle mechanism, can simultaneously engage and connect the card cover and the fixing ring, while also limiting the card cap and the card ring in the card cover, so that the card cover can be released from the limit and pressed for use when needed.

[0016] In this utility model, the magnesium-aluminum alloy bayonet based on basic subsurface oxidation technology, through the card cover, can be used as a protective cover to protect the interior and prevent accidental contact, and can also be extended and retracted when needed for coordinated use.

[0017] In this invention, during use, it can not only achieve normal protective effect to avoid accidental touch, but also limit the extension and retraction of the card cover itself, so that during normal use, the corresponding operation can be performed without removing the card cover, thereby avoiding the problem of the card cover being easily lost.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] Reference Figure 1 The bayonet includes a fixing ring 3 and a cover structure. Both the fixing ring 3 and the cover are made of magnesium-aluminum alloy and are surface treated with alkaline subsurface oxidation technology to form a dense and uniform oxide film, which effectively improves the corrosion resistance of the bayonet and extends its service life.

[0027] Reference Figure 2 The fixing ring 3 serves as the basic support for the bayonet, and the cover consists of a cap 1 and a ring 2. The ring 2 is fitted onto the outer wall of the fixing ring 3, and its inner wall has an inner sliding groove 7. The inner sliding ring 6 is fixed to the bottom of the cap 1 and slidably disposed in the inner sliding groove 7, realizing the relative sliding between the cap 1 and the ring 2.

[0028] Reference Figure 3-4A locking mechanism is located inside the retaining ring 2 to achieve engagement between the retaining ring 2 and the fixed ring 3. Specifically, the outer wall of the retaining ring 2 has at least one side sliding groove 14, and the slider 11 is slidably disposed within the side sliding groove 14. An insert plate 13 is fixed to one side of the slider 11, and one end of the insert plate 13 slides through the retaining ring 2 and engages with a groove 10 formed on the outer wall of the fixed ring 3. When the retaining ring 2 is fitted onto the fixed ring 3, the insert plate 13 is inserted into the groove 10 under the action of the slider 11, thus achieving engagement.

[0029] For the reset of slider 11, limit grooves 12 are provided on both sides of slider 11, and limit plates 16 are fixed to the inner walls of both sides of side sliding groove 14. The limit plates 16 are located in the limit grooves 12 to prevent slider 11 from falling off. A compression spring 15 is fixed between the limit grooves 12 and the limit plates 16 (the wire diameter of the compression spring 15 is 0.1-0.5mm, the outer diameter is 2-5mm, the free length range is 5-15mm, and it can provide an elastic reset force of 0.5-3N), which provides a reset force for slider 11 and ensures that the insert plate 13 remains inserted into the slot 10 when no external force is applied.

[0030] The locking mechanism also includes a rotating bar 9. The outer wall of the retaining ring 2 has a connecting groove 17, the bottom end of which connects to the top of the side sliding groove 14. The rotating bar 9 is located within the connecting groove 17, with its bottom end rotatably positioned on top of the slider 11. The outer wall of the retaining cap 1 has a notch 8, and the top end of the rotating bar 9 is located within the notch 8. By rotating the rotating bar 9, one end disengages from the notch 8, thus releasing the movement restriction between the retaining cap 1 and the retaining ring 2, allowing the retaining cap 1 to be pressed downwards. The end of the rotating bar 9 can be configured as a straight bar, L-shaped, or curved bend for easy finger operation.

[0031] This application can be used in the field of magnesium-aluminum alloy bayonet mounts, or in other fields applicable to this application.

[0032] Example 2

[0033] refer to Figure 5 An improvement based on Example 1: A magnesium-aluminum alloy bayonet based on basic subsurface oxidation technology is applied to the field of magnesium-aluminum alloy bayonet. The fixing ring 3 is fixed on the top of the bottle body, and the cap is installed outside the fixing ring 3. The pump head of the bottle body is located inside the cap. The outer wall of the cap 1 has a through hole 4. The liquid outlet end of the pump head extends to the outside through the through hole 4. The top of the outer wall of the cap 1 is fixed with an extension edge 5, which is located above the through hole 4 to prevent accidental pressure on the pump head.

[0034] Specifically, for the use and installation of the cover, first fasten the retaining ring 2 onto the outer wall of the fixing ring 3. At this time, the inclined surface of the insert plate 13 will touch the top of the fixing ring 3, causing the insert plate 13 and the slider 11 to move. When the insert plate 13 is located on one side of the slot 10, the slider 11 will be reset by the force of the compression spring 15, thereby driving the insert plate 13 to reset, so that the insert plate 13 passes through the retaining ring 2 and is locked into the inside of the slot 10, thereby realizing the connection and installation between the cover and the fixing ring 3.

[0035] When it is necessary to press the pump head, simply rotate the rotating bar 9 so that one end of the rotating bar 9 is disengaged from the inside of the notch 8. At this time, the cap 1 will lose its limiting constraint, and can be pressed down for use. This way, it can be used without removing the cap, thus avoiding the problem of the cap being easily lost.

[0036] When it is necessary to release the latch between the cover and the retaining ring 3, the rotating bar 9 can be rotated out, and the slider 11 can be moved by pulling the rotating bar 9, thereby releasing the latch between the retaining ring 3 and the cover.

[0037] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
