[0019] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0020] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the module or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0022] See Figure 1-6This utility model provides a cup lid structure, including an upper cup lid 1 and a lower cup lid 2. The upper cup lid 1 and the lower cup lid 2 are rotatably connected on one side. The upper cup lid 1 has two first ear seats 11 arranged at intervals on one side, and the lower cup lid 2 has two second ear seats 21 arranged at intervals corresponding to the two first ear seats 11 on one side. A first torsion spring 3 is provided between the interior of one first ear seat 11 and the interior of the adjacent second ear seat 21. The first torsion spring 3 is configured to reset after the upper cup lid 1 rotates relative to the lower cup lid 2. An elastic pin 4 is provided between the interior of the other first ear seat 11 and the interior of the adjacent second ear seat 21. The other first ear seat 11 has a first locking hole 111 for the elastic pin 4 to be inserted to achieve rotational guidance.

[0023] Therefore, by placing the first torsion spring 3 between the inside of the first ear seat 11 and the inside of the second ear seat 21, and placing the elastic pin 4 between the inside of the other first ear seat 11 and the other second ear seat 21, not only can the upper cup lid 1 rotate relative to the lower cup lid 2, but the connection structure between the upper cup lid 1 and the lower cup lid 2 can also be hidden, thereby ensuring the integrity of the cup lid's appearance and improving the overall aesthetics of the product.

[0024] A first shaft is provided between the interior of a first ear seat 11 and the interior of a nearby second ear seat 21, and a first torsion spring 3 is sleeved on the first shaft. A second shaft is provided between the interior of another first ear seat 11 and the interior of another nearby second ear seat 21, and an elastic ejector pin 4 is disposed on the second shaft. Specifically, the elastic ejector pin 4 includes a spring 41 and an ejector pin 42. A mounting groove is provided on the second shaft, and the spring 41 is disposed in the mounting groove. One end of the spring 41 abuts against the inner wall of the mounting groove, and the other end abuts against the ejector pin 42. Thus, under the elastic force of the spring 41, it can drive the ejector pin 42 to extend out of the second ear seat 21 and insert into the first locking hole 111 of the first ear seat 11, thereby realizing the rotational connection between the upper cup lid 1 and the lower cup lid 2.

[0025] In this embodiment, the two first ear seats 11 are located on the outer sides of the two second ear seats 21 respectively.

[0026] See also Figure 2 as well as Figure 5 It also includes a handle 6, on which a third ear seat 61 protrudes and is fitted between two second ear seats 21; in addition, it includes a rotating shaft 5 passing through the two second ear seats 21, with a through hole 611 in the third ear seat 61, through which the rotating shaft 5 passes to rotate the handle 6 onto the cup lid. One end of the rotating shaft 5 extends into the interior of one second ear seat 21 to form the aforementioned first shaft, and the other end of the rotating shaft 5 extends into the interior of the other second ear seat 21 to form the aforementioned second shaft.

[0027] Of course, it should be noted that in other embodiments, when the cup lid does not have a handle 6, the two first ear seats 11 can be embedded between the two second ear seats 21, and the first shaft and the second shaft can be set separately. This can also achieve the goal of the upper cup lid 1 being rotatably connected to the lower cup lid 2 while concealing the connection structure. Therefore, this is not a limitation. Furthermore, a second locking hole 112 is provided inside the first ear seat 11 for the first shaft body to be inserted to achieve rotational guidance. This arrangement makes the rotation of the two first ear seats 11 relative to the two second ear seats 21 more stable and smooth.

[0028] In addition, the interior of the first ear seat 11 is provided with a groove 113 surrounding the outer periphery of the second card hole 112, and the first torsion spring 3 can be partially inserted into the groove 113 to achieve contact with the first ear seat 11.

[0029] See also Figure 1-2 as well as Figure 6 The upper cup lid 1 and the lower cup lid 2 are engaged on the other side by a snap-fit ​​structure. Specifically, the upper cup lid 1 has a first retaining seat 12 on the other side, and the lower cup lid 2 has a second retaining seat 22 on the other side. The snap-fit ​​structure includes a retaining groove 121 disposed in the first retaining seat 12 and a spring snap 7 rotatably disposed in the second retaining seat 22. The spring snap 7 and the retaining groove 121 are detachably engaged to achieve the engagement between the upper cup lid 1 and the lower cup lid 2.

[0030] In this embodiment, a pin is inserted into the second card holder 22, and the spring clip 7 is rotatably mounted on the pin; it also includes a second torsion spring (not shown in the figure) sleeved on the pin and abutting against the spring clip 7, the second torsion spring being configured to reset after driving the spring clip 7 to rotate.

[0031] Therefore, when it is necessary to fasten the upper lid 1 and the lower lid 2 together, first press the snap 7 to overcome the torque of the second torsion spring and rotate it. When the upper lid 1 is placed on the lower lid 2, release the snap 7. The snap 7 can be reset under the torque of the second torsion spring and fastened into the slot 121, thereby achieving the snap-fit ​​fixation between the upper lid 1 and the lower lid 2. Similarly, when it is necessary to unlock, simply press the snap 7 to disengage it from the slot 121. At this time, under the torque of the first torsion spring 3, the upper lid 1 can spring open and reset.

[0032] The assembly process of the cup lid structure of this utility model is as follows: First, insert the third lug 61 on the handle 6 between the two second lugs 21 on the lower lid 2. Then, pass the rotating shaft 5 through one second lug 21, the third lug 61, and the other second lug 21 in sequence. Next, place the first torsion spring 3 inside one of the second lugs 21 and fit it onto the rotating shaft 5. Then, align the first lug 11 on the upper lid 1 with the second lug 21 on the lower lid 2 and assemble the first torsion spring 3 between them. During the assembly process, the rotating shaft 5 can be moved away from the first torsion spring 3 until the first torsion spring 3 is installed. After assembly, move the rotating shaft 5 closer to the first torsion spring 3 and insert its end into the second locking hole 112. Then, place the spring 41 into the mounting groove at the other end of the rotating shaft 5 and insert the ejector pin 42 into the mounting groove to compress the spring 41. Finally, align the other first ear seat 11 on the upper cup lid 1 with the other second ear seat 21 on the lower cup lid 2 until the first locking hole 111 is aligned with the ejector pin 42. The ejector pin 42 will pop out under the elastic force of the spring 41 and insert into the first locking hole 111, thus completing the assembly of the cup lid structure.

[0033] In addition, this utility model also provides a water cup, including a cup body and a cup lid structure covering the cup body.

[0034] In summary, the cup lid structure and water cup provided by this utility model, by placing the first torsion spring 3 between the inside of a first ear seat 11 and the inside of a second ear seat 21, and placing the elastic pin 4 between the inside of another first ear seat 11 and the inside of another second ear seat 21, the connection structure between the upper cup lid 1 and the lower cup lid 2 is hidden, thereby ensuring the integrity of the cup lid's appearance and improving the overall aesthetics of the product.
