[0030] In order to make the technical scheme of the utility model more clear, the following will combine the drawings of the utility model Figs. 1 to 5 , and a detailed description will be made of the utility model. It should be understood that the specific embodiments described in the specification are only for the purpose of explaining the utility model, and are not intended to limit the protection scope of the utility model.

[0031] Generally, the cup mouth of the cup body 1 has a straight section 11 and a shoulder 12, and because the inner diameter of the straight section 11 is smaller than the shoulder, the cup mouth has a cup mouth step 13 between the straight section 11 and the shoulder 12. Embodiment 1

[0032] The utility model relates to a quick-opening cup cover for sealing the mouth part of a cup body 1, comprising a cover body 2, a pull rod 3 and a flexible ring 4. The cover body 2 has a through hole, the pull rod 3 can move up and down in the through hole, and the flexible ring 4 is made of flexible material and has an annular structure. The lower end of the pull rod 3 is provided with a base 31, and the flexible ring 4 is sleeved on the pull rod 3 and placed between the base 31 and the bottom wall of the cover body 2. When the pull rod 3 is pulled up, the flexible ring 4 is squeezed and deformed to expand radially outward. After the pull rod 3 is pushed down to reset, the flexible ring 4 returns to its original shape.

[0033] Specifically, the cover body 2 has a lower end that is shaped and sized to match the shape and size of the straight section 11 of the cup mouth and can be inserted into or pulled out of the mouth part of the cup body 1. The upper end of the cover body 2 is provided with a clamping table 221 that abuts against and limits the position of the end part of the cup mouth. That is, the outer diameter of the lower end of the cover body 2 is smaller than the straight section 11 of the cup mouth, and the outer diameter of the upper end is larger than the straight section 11 of the cup mouth.

[0034] Specifically, the pull rod 3 is provided with a pull rod column 32 and a handle 33 in sequence above the base 31.

[0035] The base 31 is shaped and sized to match the shape and size of the straight section 11 of the cup mouth and can be inserted into or pulled out of the mouth part of the cup body 1. That is, the outer diameter of the base 31 is smaller than the straight section 11 of the cup mouth.

[0036] The handle 33 passes out of the through hole upward. The shape and size of the handle 33 match the shape and size of the upper end of the through hole. The handle 33 is provided to facilitate the user to pull out the pull rod 3 or to carry the water cup by the handle 33.

[0037] The pull rod post 32 is provided with a limiting buckle 321 on the side wall, the inner wall of the movable hole of the cover body 2 is correspondingly provided with a stop portion 222, the limiting buckle 321 is limited downward by the stop portion 222, and the top of the pull rod post 32 is limited upward by the top wall of the cover body 2. Therefore, the pull rod 3 cannot fall out of the cover body 2, and is limited to move up and down in the movable hole of the cover body 2. When the limiting buckle 321 is limited by the stop portion 222, a ring groove is formed between the bottom wall of the cover body 2 and the base 31, and the flexible ring 4 is clamped in the ring groove.

[0038] Specifically, the flexible ring 4 is made of a flexible material, such as silica gel, rubber, thermoplastic elastomer TPE, and thermoplastic polyurethane TPU. At present, silica gel is commonly used in the industry. As an optimization, in order to make the deformation of the flexible ring 4 expand radially outward to a greater extent, the flexible ring 4 adopts a hollow ring structure (such as a ring-shaped air bag). In the original state, the shape of the flexible ring 4 matches the cup mouth straight section 11, and the outer diameter is smaller than the inner diameter of the cup mouth straight section 11. After being squeezed and deformed, the outer diameter of the flexible ring 4 is greater than the inner diameter of the cup mouth straight section 11. As for the shape of the cross section of the flexible ring 4, it can be circular, oval, square, or semi-enclosed C-shaped (with the opening direction facing inward). In summary, the flexible ring 4 of the utility model has the functions of limiting and sealing.

[0039] When the pull rod 2 is pulled upward by force, the flexible ring 4 is squeezed by the base 31 and the bottom wall of the cover body 2, and expands radially outward after being squeezed into a flat shape, increasing the diameter. The outer edge of the expanded flexible ring 4 restricts the cup cover from being pulled out, and at the same time, forms a seal with the cup mouth, completing the sealing of the cup cover on the cup mouth, and achieving a sealed state. When drinking or filling water, the pull rod 2 only needs to be pushed downward, and the flexible ring 4 returns to its original state without being squeezed, and the sealing of the cup cover on the cup mouth is released, so that the cup cover can be taken out from the cup mouth, achieving a released state. Through the above structure, the cup cover can be quickly opened and closed, which is faster than screwing threads. Moreover, since the deformed flexible ring 4 is limited by the cup mouth step 13, the cup cover is difficult to be pulled out, and can withstand greater pressure compared to threads. Embodiment 2

[0040] Based on embodiment 1, the cup cover is provided with a lock assembly 5 to maintain the sealing state of the cup cover on the cup mouth.

[0041] Specifically, the lock assembly 5 includes two pairs of symmetrical lock hooks 51 and elastic members 52.

[0042] The lock hooks 51 are symmetrically arranged in the movable slots on both sides of the cover body 2.

[0043] The cover body 2 comprises an outer cover 21 and an inner cover 22, the inner cover 22 is arranged inside the outer cover 21; the inner cover 22 is provided with an active hole penetrating from top to bottom, and the upper end of the active hole is arranged on the top wall of the outer cover 21; a clamping post 221 is arranged on the outer side of the side wall of the inner cover 22; lock holes 211 are symmetrically arranged on the two sides of the side wall of the outer cover 21, and through grooves 223 are correspondingly arranged on the two sides of the side wall of the inner cover 22; the active through groove comprises the lock holes 211 and the through grooves 223.

[0044] The pull rod post 32 is provided with a clamping hook 322 radially inward on the upper end of the side wall.

[0045] Specifically, one end of the lock hook 51 is a pressing part 511, and the other end is a downward hook 512; the hook 512 extends into the active hole and can be matched with the clamping hook 322 to limit the downward movement of the pull rod 3, so that the bottom wall of the base 31 and the inner cover 22 continuously maintains the extrusion deformation of the flexible ring 4, and is in a locked state.

[0046] Further, the elastic member 52 is arranged between the pressing part 511 and the side wall of the inner cover 22, and provides a radial outward force for the hook 512 to maintain the locked state; by pressing the pressing part 511, the lock hook 51 moves radially inward, the elastic member 52 is compressed, the hook 512 is released from the clamping of the clamping hook 322, and the pull rod 3 can be pushed downward to restore the flexible ring 4 to its original state.

[0047] Further, the elastic member 52 is a spring, and the side of the pressing part 511 facing the hook 512 is further provided with a sleeve rod 513 for sleeving the elastic member 52, so as to avoid the problems of falling, mispositioning or displacement of the elastic member 52 during use.

[0048] Further, at least one of the end portions of the hook 512 and the clamping hook 322 is provided with a matching inclined surface; as a preferred, the end portions of the hook 512 and the clamping hook 322 are both provided with a matching inclined surface, in the released state, the clamping hook 322 is located below the hook 512, and the matching inclined surfaces of the hook 512 and the clamping hook 322 correspond to each other in the axial direction; when the pull rod 3 is pulled upward, the lock hook 51 can be driven to move inward against the elastic force of the elastic member 52 through the guiding action of the inclined surface, until the pull rod 3 is pulled to the right position, the clamping hook 322 is pulled above the hook 512, and the lock hook 51 moves radially outward under the action of the elastic member 52 to reset and keep the clamping of the hook 512, that is, in the locked state.
