[0025] The embodiments of this utility model are described in detail below. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments.

[0026] See Figures 1 to 8 This embodiment discloses a water cup, including a cup body and a cup lid, the cup lid being a convenient-to-open cup lid. The cup lid includes a connecting body 1 and a flip cover 2 rotatably connected to the connecting body 1. The connecting body 1 of the cup lid is detachably connected to the mouth of the cup body through a threaded connection. The connecting body 1 can be composed of a connecting body outer shell 3 and an inner plug 4 that engage with each other. The flip cover 2 includes a fixing part and a pressing part that is slidably installed with the fixing part. The pressing part is elastically reset forward by the elastic element 5. The bottom of the pressing part is provided with an upper engaging part 6. The flip cover 2 is provided with a latch 7. The lever 8 at the top of the latch 7 extends upward from the slide groove 9 opened at the top of the flip cover 2. The lever 8 can slide back and forth in the slide groove 9. The two different positions of the lever 8 in the slide groove 9 are defined as the locked position and the unlocked position, respectively. When the lever 8 is in the locked position of the slide groove 9, the pressing part is locked by the latch 7, and the upper engaging part 6 engages with the lower engaging part 10 of the connecting body 1. When the lever 8 is in the unlocked position of the slide groove 9, the pressing part is unlocked. Pressing the pressing part backward disengages the upper engaging part 6 from the lower engaging part 10 of the connecting body 1.

[0027] In this embodiment, the latch 7 includes a latch base plate 11, and a lever 8 is disposed on the top of the latch base plate 11. As the lever 8 slides back and forth in the slide groove 9, it drives the latch base plate 11 to slide back and forth in the sliding chamber 12 inside the flip cover 2. The front side of the latch base plate 11 is fitted against the front wall of the sliding chamber 12, and the rear side of the latch base plate 11 is provided with a column foot 13. The rear wall of the sliding chamber 12 is provided with a locking section 14 and an unlocking section 15. The unlocking section 15 is a rearward recessed avoidance groove. When the lever 8 is in the locked position of the slide groove 9, the column foot 13 of the latch 7 corresponds to the locking section 14 on the rear wall of the sliding chamber 12. At this time, the locking section 14 on the rear wall of the sliding chamber 12 blocks the rear end of the column foot 13. When the lever 8 is in the unlocked position of the slide groove 9, the column foot 13 of the latch 7 corresponds to the avoidance groove of the unlocking section 15 on the rear wall of the sliding chamber 12, and the pressing part can press backward.

[0028] In this embodiment, the fixing part of the flip cover 2 is the inner cover 16, and the pressing part is the outer cover 17 covering the inner cover 16. The outer cover 17 is slidably mounted on the inner cover 16 through the mounting groove 18 at the bottom and can slide back and forth relative to the inner cover 16. The front end of the inner cover 16 is elastically abutted against the outer cover 17 through the elastic element 5. The left and right sides of the inner cover 16 are respectively provided with sliding guide posts 19, and the left and right sides of the mounting groove 18 of the outer cover 17 are respectively provided with arc-shaped guide grooves 20. The two sliding guide posts 19 are slidably engaged with the two arc-shaped guide grooves 20 respectively. The elastic element 5 includes two springs. The two springs are respectively provided on the protrusions at the front ends of the two sliding guide posts 19. The front ends of the two springs elastically press against the outer cover 17 and the rear ends elastically press against the two sliding guide posts 19. The inner cover 16 has a downwardly extending mounting section 21 at its rear end. The mounting section 21 of the inner cover 16 and the rear end of the outer cover 17 are hinged to the connecting body 1 by the same pin 22. The mounting section 21 of the inner cover 16 has a first hinge hole 23 that mates with the pin 22. The rear end of the outer cover 17 has a second hinge hole 24 that mates with the pin 22. The first hinge hole 23 is a round hole, and the second hinge hole 24 is designed as an oblong hole, so that the outer cover 17 and the inner cover 16 can slide relative to each other. At the same time, the oblong hole mates with the pin 22, which can limit the sliding stroke of the outer cover 17 relative to the inner cover 16.

[0029] The sliding chamber 12 is located between the top surface of the inner cover 16 and the top wall of the mounting groove 18 of the outer cover 17. The top wall of the mounting groove 18 of the outer cover 17 is provided with a front limiting protrusion 25 in front of the corresponding locking base plate 11, and the top surface of the inner cover 16 is provided with a rear limiting protrusion 26 in the rear of the corresponding locking base plate 11. The top surface of the inner cover 16, the top wall of the mounting groove 18 of the outer cover 17, the front limiting protrusion 25, and the rear limiting protrusion 26 together form the sliding chamber 12.

[0030] The front side of the latch base plate 11 is provided with a positioning claw 27, and the rear side of the front limiting protrusion 25 of the outer cover 17 is provided with a positioning groove 28. The positioning groove 28 is provided with two positioning sections 29, which respectively engage with the positioning claw 27 when the lever 8 of the latch 7 is in the locked position and the unlocked position, so as to realize the positioning of the latch 7 in the locked and unlocked states, so as to prevent the latch 7 from moving at will. Only when sufficient external force is applied can the latch 7 be pushed to move left and right.

[0031] A flexible pressing plug 30 is embedded on the front side of the outer cover 17, serving as the pressing part of the outer cover 17. The bottom of the inner cover 16 is provided with a sealing plug for sealing the drinking port on the connector 1. The drinking port on the connector 1 has a dual drinking port structure, including a sippy port 31 and a direct drinking port 32 arranged side by side. The bottom of the sealing plug is provided with two sealing plug bodies 33, which are used to seal the two drinking ports respectively.

[0032] When the lever 8 of the latch 7 is in the locked position of the slide groove 9, the column foot 13 of the latch 7 corresponds to the locking section 14 on the rear wall of the sliding chamber 12. At this time, the locking section 14 on the rear wall of the sliding chamber 12 blocks the rear end of the column foot 13, so that the outer cover 17 cannot be pressed backward, thereby locking the outer cover 17 in the closed state and effectively preventing the flip cover 2 from being opened due to accidental contact.

[0033] When it is necessary to open the flip cover 2, first move the lever 8 of the latch 7 to the unlock position. The lever 8 moves the latch base plate 11 together, causing the column foot 13 on the rear side of the latch base plate 11 to be misaligned with the locking section 14 on the rear wall of the sliding chamber 12, and to correspond with the clearance groove of the unlocking section 15 on the rear wall of the sliding chamber 12. At this time, since there is no obstruction, the latch base plate 11 and the outer cover 17 can move backward. Then press the outer cover 17 backward, the spring is compressed, and the outer cover 17 moves backward relative to the inner cover 16. The upper engaging part 6 of the outer cover 17 disengages from the lower engaging part 10 of the connecting body 1, and the flip cover 2 can be opened. Release the outer cover 17, and under the action of the two springs, the outer cover 17 automatically returns to its original position. When closing the flip cover 2 again, move the lever 8 of the latch 7 in the opposite direction to the locking position to lock the closed flip cover 2. Locking and unlocking the latch 7 only requires pushing the lever 8 of the latch 7 laterally, which is convenient and quick to operate.

[0034] In this embodiment, the flip cover 2 is designed as a split structure, consisting of an inner cover 16 and an outer cover 17 that slide relative to each other. A sliding chamber 12 is formed between the inner cover 16 and the outer cover 17 for the locking base plate 11 to slide. The inner and outer covers 17 are hinged together on the connecting body 1 by the same pin 22. At the same time, the second hinge hole 24 at the rear end of the outer cover 17 that cooperates with the pin 22 is designed as an oblong hole, which not only ensures that the outer cover 17 and the inner cover 16 can slide relative to each other, but also limits the sliding stroke of the outer cover 17 relative to the inner cover 16. The structure is ingeniously designed and the layout is compact.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
