Detailed Implementation

[0016] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0017] like Figure 1-7 As shown, a flip-top cup lid with a locking mechanism includes a lid base 1, a connecting base 2, and a flip cover 3. The lid base 1 includes a threaded connecting base connected to the cup body. A first mounting base 101 and a second mounting base 102 are provided on the end face of the threaded connecting base away from the cup body. The first mounting base 101 is provided with a water outlet 103 and a vent hole 104. The second mounting base 102 is provided with a connecting groove 105. Sliding columns 106 are symmetrically arranged on the outer wall of the first mounting base 101 near the second mounting base 102, and gears 4 are movably sleeved on the sliding columns 106. A push rod 5 is meshed between the two gears 4, and one end of the push rod 5 movably passes through the connecting groove 105, while the other end forms a gap with the outer wall of the first mounting base 101. A locking ring 6 is fitted on the outer side of the mounting base 101, and the locking ring 6 is elastically connected to the second mounting base 102, meshing with two gears 4, and slidingly connected to two sliding columns 106 and the positioning groove 107 on the first mounting base 101. A rotating wheel 7 is rotatably connected in the connecting groove 105, and a first locking structure is provided between the rotating wheel 7 and the connecting groove 105. The connecting base 2 passes through the first mounting base 101 and the second mounting base 102 and is connected to the cup lid base 1, and covers the rotating wheel 7 so that one end of the rotating wheel 7 is exposed outside the connecting base 2. The flip cover 3 is elastically rotatably connected to the connecting base 2, and a second locking structure is provided between the flip cover 3 and the locking ring 6.

[0018] When the cover needs to be opened, first rotate the rotating wheel 7 to unlock the rotating wheel 1 from the connecting groove 105. At this time, the rotating wheel 7 can move inward along the connecting groove 105. Pushing the rotating wheel 7 inward will cause the push rod 5 to move inward at the same time. The movement of the push rod 5 will cause the two gears 4 to rotate. The rotation of the gears 4 will cause the locking ring 6 to move elastically towards the second mounting base 102, thereby disengaging the flip cover 3 from the locking ring 6, thus completing the opening operation of the flip cover 3. Releasing the rotating wheel 7 will cause the locking ring 6 to spring back into place, and drive the push rod 5 and the rotating wheel 7 to return to their positions together. When the cover needs to be closed, simply press down on the flip cover 3 to connect it with the locking ring 6, and finally rotate the rotating wheel 7 in the opposite direction to lock it.

[0019] The cup lid of this utility model, through the arrangement of the rotating wheel 7, the push rod 5, and the locking ring 6, and adopting a gear-type working structure, allows the rotating wheel 7 to be locked with the connecting groove 105 by rotating the rotating wheel 7, thus preventing the rotating wheel 7 from being pushed inward and avoiding accidental opening of the flip cover 3 by external force touching the rotating wheel 7, ensuring the locking stability between the flip cover 3 and the locking ring 6. It also allows the rotating wheel 7 to be unlocked from the connecting groove 105, and then stably drive the push rod 5 and the locking ring 6 to move in sequence, realizing the unlocking of the flip cover 3 and the locking ring 6. The operation is convenient, and the gear-type working process is more stable and precise, improving the stability and safety of the cup lid.

[0020] Preferably, the sliding column 106 is provided with a first connecting column 108, and the gear 4 is movably sleeved on the first connecting column 108. The push rod 5 includes an integrally formed connecting block 501 and a slider 502. The connecting block 501 has tooth grooves 503 on both sides that mesh with the two gears 4. The slider 502 passes through the notch of the connecting groove 105 and moves back and forth along the connecting groove 105. A push block 504 is also provided on the connecting block 501. A limiting boss 505 is provided at the end of the push block 504 near the rotating wheel 7. The above design has a simple structure, which makes the connection between the push rod 5 and the gear 4 more compact and the cooperation more stable. The design of the push block 504 makes the contact between the push rod 5 and the rotating wheel 7 more stable, ensuring the stability of their operation.

[0021] Preferably, the first locking structure includes a first locking groove 109 and a first locking block 703. The first locking groove 109 is disposed in the connecting groove 105. The rotating wheel component 7 includes a rotating rod 701 and a rotating wheel 702 disposed on the rotating rod 701. The rotating rod 701 is sleeved in the connecting groove 105, and the first locking block 703 protrudes from the outer wall of the rotating rod 701. The outer wall of the slider 502 is also provided with a first limiting groove 506 for mounting the first locking block 703, and the outer wall of the rotating wheel 702 is provided with two second limiting grooves 704 for mounting the limiting bosses 505.

[0022] In the above design, the first locking groove 109 can specifically be a concave pointed groove on the inner wall of one side of the connecting groove 105, and the first locking block 703 can be a protruding block on the outer wall of the rotating rod 701 that can be turned into the pointed groove and locked. As long as the two can be fitted together, the locking and unlocking operations between the rotating wheel 7 and the connecting groove 105 can be realized. The design of the first limiting groove 506 on the slider 502 allows the first locking block 703 to be locked in the first limiting groove 506 when the rotating wheel 7 is in the unlocked state, realizing the positioning connection between the rotating wheel 7 and the push rod 5, which can improve the synchronous movement stability between the two. When the rotating wheel 7 is locked... When the push rod 5 is fixed in the connecting groove 105, the limiting boss 505 on the push rod 5 is locked in one of the second limiting grooves 704, which can improve the stability of the locked state. When the rotating wheel 7 rotates and unlocks from the connecting groove 105, the limiting boss 505 is locked in the other second limiting groove 704, which can make the synchronous movement between the rotating wheel 7 and the push rod 5 more stable. The two second limiting grooves 704 are connected by an arc-shaped transition surface. This requires a certain amount of force to rotate the rotating wheel 7, avoiding easy activation by accidental forces, and makes the rotation process of the rotating wheel 7 smoother and more stable.

[0023] Preferably, the outer wall of the aforementioned rotating wheel 702 is also provided with a groove 705. The above design facilitates the operation of the rotating wheel 7 through the groove 705, and also makes it easy to visually identify a state of the rotating wheel 7, that is, a state of use of the cup lid.

[0024] Preferably, the locking ring 6 includes a ring body with a connector. The connector has a latch for engaging the second mounting base 102, and the latch has a second connecting post 601.

The connector has symmetrically arranged sliding holes 602 for passing through the first connecting post 108, sliding grooves 603 for corresponding connection of the sliding post 106, and toothed connecting blocks 604 for engaging the gear 4. The toothed connecting blocks 604 correspond to the connecting blocks 501 on the push rod 5. This design facilitates the assembly of the locking ring 6 with the various accessories, improves the overall compactness of the cup lid structure, and enhances the stability of their synchronous movement. The gear 4 is located above the sliding holes 602 and engages with the toothed connecting blocks 604.

[0025] Preferably, the second locking structure includes a second locking groove 606 and a second locking block 301. A positioning block 605 protrudes from the inner wall of the ring facing the connector, and the second locking groove 606 is disposed on the positioning block 605. The positioning block 605 moves along the positioning groove 107, and the second locking block 301 is disposed on the inner side of the flip cover 3. In the above design, the shapes of the second locking groove 606 and the second locking block 301 are designed to match, ensuring that the locking block 301 can be engaged and fixed in the locking groove.

[0026] Preferably, the connecting seat 2 is provided with a protective platform 201 for covering the rotating wheel 7, and a positioning notch 202 for the positioning block 605 and the second locking block 301 to pass through.
