[0028] Figure 4 It is a schematic structural diagram of the cooperation between the outer cover and the elastic ring in the present utility model; Figure 5 It is a schematic structural diagram of the water cup cover in the present utility model. Please refer to Figures 1 to 5As shown, a water cup cover is shown, including an inner plug 1, and an outer cover 3 arranged at the upper end of the cover body 2, and also including an assembly shaft 4 and an elastic ring 5. The lower end of the outer cover 3 is provided with an assembly shaft 4, and the assembly shaft 4 is provided with an elastic ring 5. The cover body 2 is provided with a drinking port 14, and the outer cover 3 is provided with a cutout 15 corresponding to the drinking port 14. The cover body 2 is provided with an assembly hole 6, and the outer diameter of the elastic ring 5 is larger than the inner diameter of the assembly hole 6. The elastic ring 5 is inserted through the assembly hole 6 by elastic deformation and then abuts against the lower end of the assembly hole 6. The elastic ring 5 and the assembly hole 6 are in interference fit. The elastic ring 5 is rotatably arranged in the assembly hole 6, and the lower end of the outer cover 3 is provided with a first clamping point 7, and the cover body 2 is provided with a second clamping point 8 that cooperates with the first clamping point 7. In this embodiment, refer to Figure 1 As shown, a first sealing ring 16 is provided at the outer edge of the lower end of the inner plug 1 for cooperation with the cup body, wherein an outer cover 3 is provided at the upper end of the cover body 2. The assembly hole 6 is provided in the middle of the cover body 2, and an assembly shaft 4 is provided in the middle of the lower end of the outer cover 3. The assembly shaft 4 and the outer cover 3 can be connected in one piece, and the elastic ring 5 is provided on the assembly shaft 4 for cooperation with the assembly hole 6 to realize the installation between the outer cover 3 and the cover body 2, and the outer cover 3 can rotate relative to the cover body 2. By pressing down the outer cover 3, the elastic ring 5 on the assembly shaft 4 can be squeezed to produce elastic deformation, so as to penetrate and insert into the lower end of the assembly hole 6, so as to realize the installation between the assembly shaft 4 and the assembly hole 6.
[0029] The first clamping point 7 and the second clamping point 8 cooperate with each other. At the moment when the outer cover 3 is opened or closed, the first clamping point 7 on the outer cover 3 will cross over the second clamping point 8 on the cover body 2, and the outer cover 3 will be lifted upward. During the lifting process, the outer cover 3 is subjected to the downward rebound tension applied by the elastic ring 5, so an operation buckle feeling will be generated after passing over the clamping point, thereby locking the open and closed position of the outer cover 3. At least one first clamping point 7 is provided at the lower end of the outer cover 3, and at least one second clamping point 8 cooperating with the first clamping point 7 is provided at the upper end of the cover body 2. The specific number of the first clamping point 7 and the second clamping point 8 can be selected according to needs. See Figure 2 and Figure 3 As shown, in this embodiment, two first clamping points 7 and two second clamping points 8 can be provided, the two first clamping points 7 are symmetrically arranged on both sides of the assembly axis 4, and the two second clamping points 8 are symmetrically arranged on both sides of the assembly hole 6.
[0030] Further, as a preferred embodiment, it also includes a positioning step 9, two positioning steps 9 are provided on the assembly shaft 4, and the elastic ring 5 is provided between the two positioning steps 9. Figure 1 As shown, two positioning steps 9 are arranged at the upper and lower ends of the assembly shaft 4 to limit the position of the elastic ring 5 and prevent the elastic ring 5 from moving up and down or separating from the assembly shaft 4. By setting the two positioning steps 9, the elastic ring 5 will not separate from the assembly shaft 4 when the assembly shaft 4 rotates.
[0031] Furthermore, as a preferred embodiment, a first limiting rib 10 is provided at the lower end of the outer cover 3, and a second limiting rib 11 that cooperates with the first limiting rib 10 is provided at the upper end of the cover body 2. Among them, the first limiting rib 10 is located on one side of the assembly shaft 4. The second limiting rib 11 is provided at one end of the assembly hole 6. The first limiting rib 10 and the second limiting rib 11 cooperate with each other to limit the rotation range of the outer cover 3 and determine the opening and closing positions of the outer cover 3. When the outer cover 3 is rotated, the outer cover 3 will drive the first limiting rib 10 to hit the second limiting rib 11, indicating that the outer cover 3 has reached the open or closed position at this time.
[0032] Furthermore, as a preferred embodiment, elastic protrusions 12 are provided on the outer edges of both sides or the middle outer edge of the elastic ring 5. In this embodiment, when the elastic protrusions 12 are installed on the outer edges of both sides of the elastic ring 5, when the elastic ring 5 is squeezed into the assembly hole 6, the elastic protrusions 12 at the lower end of the elastic ring 5 will abut against the lower outer wall of the assembly hole 6, and the elastic protrusions 12 at the upper end of the elastic ring 5 will abut against the upper outer wall of the assembly hole 6, thereby realizing the installation between the elastic ring 5 and the assembly hole 6. When the elastic protrusions 12 are installed on the middle outer edge of the elastic ring 5, when the elastic ring 5 is squeezed and installed in the assembly hole 6, the elastic protrusions 12 in the middle of the elastic ring 5 are located on the lower side of the assembly hole 6 and abut against the lower outer wall of the assembly hole 6, realizing the installation between the elastic ring 5 and the assembly hole 6.
[0033] Among them, the elastic protrusion 12 can be in the shape of a tongue piece or an arc or other shapes, as long as it can abut against the lower outer wall of the assembly hole 6.
[0034] In this embodiment, by utilizing the elastic characteristics of the elastic ring 5 itself, the disassembly of the outer cover 3 and the cover body 2 is also very simple. From the inside of the cover body 2, hold the assembly shaft 4 and push it outwards, and the elastic ring 5 can be separated from the assembly hole 6 due to the elastic deformation caused by extrusion, completing the disassembly of the outer cover 3.
[0035] Furthermore, as a preferred embodiment, an operation rib position 13 is further included, and the operation rib position 13 is provided at the upper end of the outer cover 3. The operation rib position 13 is integrally connected to the middle of the upper end of the outer cover 3. By rotating the operation rib position 13, the outer cover 3 is driven to rotate on the upper end of the cover body 2. When the outer cover 3 is driven to rotate through the operation rib position 13, until the cutout 15 on the outer cover 3 is directly opposite to the drinking port 14 on the cover body 2, it indicates that the outer cover 3 is in the open state at this time, facilitating drinking. When it is necessary to close the outer cover 3, the outer cover 3 in the open state can be rotated 180° or other angles, as long as there is no overlapping area between the cutout 15 and the drinking port 14, the outer cover 3 can be closed.
[0036] The water cup lid in this embodiment can be applied to a water cup. For example, a shown water cup includes a cup body 17, and the water cup lid is detachably arranged on the cup body 17.
[0037] Please refer to Figures 6 to 7 As shown, the water cup lid in this embodiment may be provided with an inner plug 1 or may not be provided with the inner plug 1, which is specifically selected according to needs. When the inner plug 1 is provided, the inner plug 1 is arranged at the lower end of the lid body 2. Specifically, refer to Figure 1 As shown, a first sealing ring 16 is arranged on the outer wall of the lower end of the inner plug 1 to achieve sealing with the cup body 17. Threads are arranged on the outer peripheral wall of the inner plug 1, and the inner plug 1 and the cup body 17 can be matched through the threads to achieve detachable connection.
[0038] When the inner plug 1 is not provided, a second sealing ring 18 can be directly arranged on the outer wall of the lid body 2, and the lid body 2 can be directly clamped on the cup body 17 through the second sealing ring 18.
[0039] The above are only the preferred embodiments of the present utility model, and thus do not limit the implementation manners and protection scope of the present utility model. For those skilled in the art, it should be realized that all the equivalent replacements and obvious changes made by using the description and illustrations of the present utility model should be included in the protection scope of the present utility model.
