Description

Technical Field

[0001] The utility model relates to the field of drinking water containers, in particular to a locking structure of a drinking water container switch. Background Art

[0002] Now as people pay more attention to the expression of personal style, water cups, as people's daily necessities, have also appeared in more styles and shapes. In particular, various customized convex patterns designed on the cup lids have been sought after by more and more young people.

[0003] Traditional cup lids seal by screwing them onto the cup body so that the cup lid blocks the cup mouth. However, cup lids with protruding patterns cannot be completely screwed onto the cup mouth. As a result, water cups with blocks in the threaded grooves of the cup lids are available on the market. The blocks are used to lock the cup body to achieve the effect of sealing the cup mouth. However, the blocks are generally made of plastic, which makes the blocks themselves not strong enough and can be easily squeezed and deformed. Users may easily turn the cup body too hard during use, causing it to over-twist. This makes it inconvenient to use. Utility Model Content

[0004] In order to solve the above problems, the utility model proposes a locking structure for a drinking water container switch, which solves the problem that the stopper of a traditional water cup cover is not firm enough and is not convenient to use.

[0005] The technical solution adopted by the utility model is: a locking structure of a drinking water container switch, comprising a cover body and a cup body, the cover body and the cup body are threadedly connected, a first threaded portion is arranged on the side wall of the cup body, a first threaded head is arranged on the first threaded portion, a second threaded portion is arranged on the side wall of the cover body, the second threaded portion comprises a threaded protrusion and a threaded groove, a limiting column for abutting the first threaded head is arranged in the threaded groove, and the material hardness of the limiting column is greater than the material hardness of the second threaded portion.

[0006] By means of the above technical scheme, after aligning the bottom end of the second threaded portion of the cup cover with the first threaded head of the first threaded portion of the cup body, the cup cover is rotated so that the second threaded portion is screwed into the first threaded portion until the first threaded head abuts against the limiting post, and the limiting post locks the cup body. The user stops rotating the cup cover, and the cup cover blocks the opening of the cup body, so that the user can open or close the water cup very conveniently. The material hardness of the limiting post is greater than that of the second threaded portion, so that when the limiting post is squeezed by the first threaded head, the deformation of the limiting post is extremely slight, thereby avoiding the problem of over-tightening the limit post due to excessive deformation of the limit post when the user tightens the cup cover. The user only needs to tighten the cup cover on the cup body until the first threaded head abuts against the limiting post to assemble the water cup in place, which is very convenient to use.

[0007] Furthermore, the limiting column is made of plastic material, metal material or alloy material.

[0008] Through the above technical solution, as long as the material hardness of the limit column is greater than the material hardness of the second threaded portion, the factory can use plastic material to make the limit column to reduce production costs; and the limit column made of metal or alloy material not only has a material hardness greater than the material hardness of the second threaded portion, but also has better durability, which greatly increases the service life of the water cup.

[0009] Furthermore, a second thread head and a thread bottom are provided on the thread protrusion, and the limiting column is provided on the second thread head; or, the limiting column is provided between the second thread head and the thread bottom, and in the screwing direction of the second thread portion, the limiting column is closer to the second thread head than to the thread bottom.

[0010] Through the above technical solution, when tightening the cup lid, the user needs to screw most of the second threaded portion into the first threaded portion on the cup body to avoid insufficient airtightness of the cup due to too little part of the cup lid being screwed into the cup body. This makes the threaded connection between the cup lid and the cup body very stable, ensuring the sealing of the cup lid to the opening of the cup body.

[0011] Furthermore, a mounting groove is provided on the thread groove, the limiting column is inserted into the mounting groove, and the second threaded portion is made of plastic material.

[0012] Through the above technical solution, the limiting column is inserted into the installation groove, which makes it very convenient to install the limiting column on the cover body. The limiting column made of metal or alloy makes the limiting column as a whole very strong, and the second threaded part made of plastic is convenient for mass production in the factory.

[0013] Furthermore, a limiting protrusion is provided on the threaded groove, the limiting column, the mounting groove and the limiting protrusion are arranged in sequence along the screwing direction of the cup body, and the limiting protrusion is provided with a receiving groove for mounting the limiting column.

[0014] Through the above technical solution, the limiting column is installed in the accommodating groove of the limiting protrusion so that the limiting column can disperse the pressure to the limiting protrusion when being squeezed, so that the overall structure of the cup cover is more stable.
