Description

Technical Field

[0001] The utility model relates to the technical field of snap fasteners, in particular to a bayonet. Background Art

[0002] With the continuous improvement of living standards, people's demand for cosmetics is also increasing. At the same time, there are also various cosmetic packaging bottles. When traveling, people generally carry a cosmetic dispensing bottle to carry liquid cosmetics. A bayonet for sealing is provided on the dispensing bottle. At the same time, in order to ensure the aesthetics of the bayonet, the bayonet is generally made of magnesium alloy material.

[0003] In the prior art, a bayonet is generally provided with a lid for sealing. When in use, the user needs to first remove the lid to make the inside of the bayonet unobstructed, so that the liquid in the cosmetic bottle can be poured out of the bottle smoothly. Since the lid is in the external environment for a long time, under the action of external force, the lid will rotate, thus loosening the connection between the lid and the bayonet. The liquid in the cosmetic bottle may leak, causing economic losses and being inconvenient to use. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the defect that in the prior art, since the lid is in the external environment for a long time, under the action of external force, the lid will rotate, thus loosening the connection between the lid and the bayonet, and the liquid in the cosmetic bottle may leak, and a bayonet is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A bayonet, comprising a cosmetic bottle body, and a threaded bayonet tube is fixed at the top end of the cosmetic bottle body;

[0007] A lid, the lid comprises a sub-lid and a main lid, the sub-lid is threadedly connected to the surface of the threaded bayonet tube, the main lid is sleeved on the surface of the sub-lid, and a set of intermittent connection components are arranged between the sub-lid and the main lid, and the intermittent connection components are used to adjust the connection relationship between the sub-lid and the main lid;

[0008] And a positioning component used in cooperation with the intermittent connection component, the positioning component is arranged between the sub-lid and the main lid for positioning the main lid;

[0009] A sealing seat, the sealing seat is fixed on the surface of the threaded bayonet tube, a first extrusion sealing pad and a second extrusion sealing pad are arranged in the sealing seat, and the first extrusion sealing pad and the second extrusion sealing pad are respectively matched with the bottom ends of the main lid and the sub-lid for sealing.

[0010] In a possible design, the connecting component includes a first groove formed on the surface of the secondary cover. A plurality of fixed extrusion rods are fixed in the first groove, and the plurality of fixed extrusion rods are evenly distributed in the first groove. A plurality of clamping gaps are formed between the plurality of fixed extrusion rods. At least two movable extrusion rods are fixed to the inner wall of the main cover, and the two movable extrusion rods are respectively clamped with two corresponding clamping gaps. Semi-circular extrusion blocks are fixed to the ends of the two movable extrusion rods and the plurality of fixed extrusion rods that are close to each other.

[0011] In a possible design, the positioning component includes a second groove formed at the top end of the secondary cover. A turntable is rotatably arranged in the second groove, and a strong tension spring is fixed to the side end of the turntable. The side end of the strong tension spring is fixed inside the main cover.

[0012] In a possible design, two arc-shaped grooves are formed at the top end of the main cover, and the two arc-shaped grooves are used to facilitate the finger to contact and press against the top end of the secondary cover.

[0013] In a possible design, an anti-slip sleeve ring is fixed to the surface of the main cover.

[0014] In a possible design, the threaded bayonet tube, the secondary cover and the main cover are all made of aluminum-magnesium alloy.

[0015] In this application, during use, insert a finger into the arc-shaped groove to press against the top end of the secondary cover, and hold the anti-slip sleeve ring with the other fingers. The fingers holding the anti-slip sleeve ring pull the anti-slip sleeve ring and the main cover upward. The upward movement of the main cover drives the two movable extrusion rods to rise. The two movable extrusion rods rise into the corresponding clamping gaps, and the plurality of fixed extrusion rods limit the movement of the two movable extrusion rods. At this time, rotate the main cover. The main cover drives the secondary cover to rotate through the clamping of the movable extrusion rods and the plurality of fixed extrusion rods, so that the secondary cover can be threadedly connected to the surface of the threaded bayonet tube. After releasing the hand, the strong tension spring pulls the main cover back to its original position, so that the two movable extrusion rods are disengaged from the clamping gaps. At this time, rotate the main cover, and the two movable extrusion rods will rotate in the lower half of the first groove and will not drive the secondary cover to rotate. Therefore, external bumps will not affect the connection between the secondary cover and the threaded bayonet tube, ensuring the stability of the seal.

[0016] In the present utility model, for the bayonet, through the intermittent connection component, the effect of synchronously connecting the secondary cover and the main cover when needed and canceling the synchronous connection between the secondary cover and the main cover when not needed can be achieved;

[0017] In the present utility model, for the bayonet, through the positioning component, the effect of keeping the secondary cover and the main cover not synchronously connected without external interference can be achieved;

[0018] In the present utility model, in this technical solution, the originally single lid is divided into two parts, namely a secondary lid and a main lid. The secondary lid is responsible for the connection between the original lid and the threaded bayonet tube. The main lid is sleeved on the surface of the secondary lid. Driven by the positioning component, the synchronous connection relationship between the secondary lid and the main lid is released. When the main lid rotates, it cannot drive the secondary lid to rotate synchronously. Therefore, when the main lid on the outside is interfered by an external force and rotates, it will not affect the connection relationship between the secondary lid and the threaded bayonet tube, making the connection between the secondary lid and the threaded bayonet tube more stable and preventing liquid leakage. At the same time, the intermittent connection component can be used to drive the secondary lid and the main lid to be synchronously connected. When the main lid is rotated, the secondary lid is driven to rotate synchronously, and the threaded bayonet tube can be normally opened or sealed, which is convenient for use.
