Detailed implementation mode

[0032] The following are specific embodiments of the present invention and, in combination with the accompanying drawings, further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0033] As Figures 1-9 As shown, a cup cover includes: a cover base 100, the cover base 100 is provided with a drinking opening 110, the peripheral wall part of the cover base 100 includes an inner peripheral wall 120 and an outer peripheral wall 130, the inner peripheral wall 120 is located inside the outer peripheral wall 130 and the two are concentrically arranged, and an annular mounting cavity 140 is formed between the inner peripheral wall 120 and the outer peripheral wall 130; a flip cover 200, the flip cover 200 is hinged to the cover base 100, the stroke position of the flip cover 200 includes a closed position, and when the flip cover 200 is in the closed position, it seals the drinking opening 110; an inner rotating ring 300, the inner rotating ring 300 is rotatably installed in the annular mounting cavity 140, the inner rotating ring 300 has a lock 310, and the stroke position of the inner rotating ring 300 includes a locked position and an unlocked position; when the inner rotating ring 300 is in the locked position, the lock 310 can lock the flip cover 200 to limit the opening of the flip cover 200; when the inner rotating ring 300 is in the unlocked position, the lock 310 is separated from the flip cover 200 and the flip cover 200 is allowed to be opened; an outer rotating ring 400, the outer rotating ring 400 is rotatably sleeved on the outer peripheral surface of the outer peripheral wall 130, the outer rotating ring 400 is connected to the inner rotating ring 300, when the outer rotating ring 400 rotates, it drives the inner rotating ring 300 to rotate, and the stroke position of the inner rotating ring 300 is determined by the stroke position of the outer rotating ring 400.

[0034] The cover base 100 is the basic part of the cup cover. The feature of the cover base 100 is the design of a double-layer peripheral wall. An annular installation cavity 140 is formed between the two walls. The flip cover 200 is hinged to the cover base 100. The main function of the flip cover 200 is to cover the cover base 100 and seal the drinking port 110 to prevent the liquid in the cup from leaking out of the drinking port 110. The inner rotating ring 300 is located in the annular installation cavity 140 and can rotate freely. A lock catch 310 is provided on the inner rotating ring 300. When the inner rotating ring 300 is in the locked position, the lock catch 310 can lock the flip cover 200 to prevent it from opening; when the inner rotating ring 300 is in the unlocked position, the lock catch 310 is separated from the flip cover 200, and the flip cover 200 can be freely opened. The outer rotating ring 400 is sleeved outside the outer peripheral wall 130 and can also rotate freely. The outer rotating ring 400 is connected to the inner rotating ring 300, so the inner rotating ring 300 can be driven to rotate by twisting the outer rotating ring 400, thereby adjusting the stroke position of the inner rotating ring 300.

[0035] The working principle of this cup cover is as follows: The user rotates the outer rotating ring 400 to a certain specific position, causing the inner rotating ring 300 to rotate to the locked position. At this time, when the flip cover 200 is rotated to the closed position, the flip cover 200 will be locked by the lock catch 310, restricting the opening of the flip cover 200. Since the outer rotating ring 400 is not easily rotated by external impacts or vibrations, it is ensured that the flip cover 200 is not easily opened due to accidental triggering; when the flip cover 200 needs to be opened, the user rotates the outer rotating ring 400 in the opposite direction, causing the inner rotating ring 300 to rotate to the unlocked position. The lock catch 310 on the inner rotating ring 300 is separated from the flip cover 200, releasing the lock on the flip cover 200, and the flip cover 200 opens to expose the drinking port 110.

[0036] Through the linkage mechanism of the inner and outer rotating rings 400, the problem of accidental opening of the flip cover 200 caused by accidental touching of a button is effectively avoided. The user only needs to rotate the outer rotating ring 400 to complete the locking and unlocking operations without an additional button, simplifying the operation steps. Compared with the traditional button design, the rotary design reduces mechanical wear and extends the service life of the product. Moreover, the design of the outer rotating ring 400 can be integrated with the overall style of the cup cover, making there be no button design on the appearance of the cup cover.

[0037] As Figures 1-4 shown, on the basis of the above-mentioned embodiment, a first clearance groove 131 is provided on the outer peripheral wall 130, and a connecting buckle 410 is provided on the inner peripheral surface of the outer rotating ring 400. The connecting buckle 410 passes through the first clearance groove 131 and is connected to the inner rotating ring 300 so that the inner rotating ring 300 and the outer rotating ring 400 move synchronously.

[0038] The connecting buckle 410 is designed to transfer the torsional movement of the outer rotating ring 400 to the inner rotating ring 300, so that when the outer rotating ring 400 rotates, it can drive the inner rotating ring 300 to rotate; the first clearance groove 131 is designed to ensure that the connecting buckle 410 can pass through the outer peripheral wall 130 and be connected to the inner rotating ring 300, ensuring that the rotation of the outer rotating ring 400 can directly drive the inner rotating ring 300 to rotate synchronously. The first clearance groove 131 extends along the circumferential direction of the outer peripheral wall 130, and the dimension of the first clearance groove 131 in the circumferential direction is equal to the rotation stroke of the outer rotating ring 400. When the outer rotating ring 400 rotates within the stroke range, the connecting buckle 410 moves within the first clearance groove 131 and there is no interference between the two.

[0039] Preferably, the end shape of the connecting buckle 410 is usually convex or hook-shaped. After the connecting buckle 410 passes through the first clearance groove 131, it is connected to the corresponding structure (such as a groove or a hole) on the inner rotating ring 300 to ensure that the rotation of the outer rotating ring 400 can directly drive the inner rotating ring 300 to rotate synchronously.

[0040] The inner peripheral surface of the outer rotating ring 400 has a plurality of connecting buckles 410, and a plurality of first clearance grooves 131 are provided on the outer peripheral wall 130. The number of the first clearance grooves 131 is equal to that of the connecting buckles 410 and they are arranged in one-to-one correspondence.

[0041] On the basis of the above embodiment, the outer rotating ring 400 is provided as a split structure and includes two semi-ring members 430. The ends of the two semi-ring members 430 are butted, and both of the two semi-ring members 430 are provided with connecting buckles 410. Both of the two semi-ring members 430 are connected to the inner rotating ring 300 through the connecting buckles 410.

[0042] Since the outer rotating ring 400 is composed of two semi-ring members 430, the split design enables each semi-ring member 430 to be installed independently and be butted into a complete ring structure after assembly. This design greatly simplifies the installation process. Especially when the outer rotating ring 400 needs to be sleeved on the already assembled cup lid, the split design can avoid complex assembly steps. If it is a complete ring structure, it cannot be sleeved on the outer peripheral wall 130.

[0043] On the basis of the above embodiment, both ends of the two semi-ring members 430 each have a half connecting buckle 410, and the half connecting buckles 410 on the two semi-ring members 430 are joined together and connected to the inner rotating ring 300.

[0044] In the actual structure, each half-ring member 430 has not only a complete connecting buckle 410, but also half a connecting buckle 410. The two half-ring members 430 can form a connecting buckle 410 after being docked. After the ends of the two half-ring members 430 are docked, the half connecting buckles 410 are spliced together to form a complete connecting buckle 410. After this spliced connecting buckle 410 is inserted into the inner rotating ring 300, the ends of the two half-ring members 430 can be constrained together, ensuring that the overall structure of the outer rotating ring 400 is stable and will not loosen or dislocate during use.

[0045] like Figures 1-9 As shown, on the basis of the above embodiment, it also includes a dial button 500, which can be slidably installed in the annular mounting cavity 140, the dial button 500 has a protrusion 510, and the outer peripheral wall 130 is provided with a second air avoidance groove 132, the protrusion 510 passes through the second air avoidance groove 132 and the dial button 500 is locked with the outer peripheral wall 130 in the circumferential direction, the outer rotating ring 400 is provided with a locking groove 420, and the stroke position of the dial button 500 includes a safety position and a free position. When the inner rotating ring 300 is in the locked position, the locking groove 420 is partially connected to the second air avoidance groove 132 and the dial button 500 is allowed to move from the free position to the safety position. When the dial button 500 is in the safety position, the protrusion 510 is embedded in the locking groove 420 and limits the rotation of the outer rotating ring 400 to limit the inner rotating ring 300 to the locked position. When the dial button 500 is in the free position, the protrusion 510 is separated from the locking groove 420 so that the outer rotating ring 400 is allowed to rotate.

[0046] The protrusion 510 on the dial button 500 passes through the second escape groove 132 on the outer peripheral wall 130, ensuring that the dial button 500 is locked to the outer peripheral wall 130 in the circumferential direction. The dial button 500 has only the freedom to move up and down, that is, the protrusion 510 can switch back and forth between the upper and lower parts of the second escape groove 132. When the dial button 500 is in the free position, the protrusion 510 is located in the upper part of the second escape groove 132. When the dial button 500 is in the safe position, the protrusion 510 is located in the lower part of the second escape groove 132. The locking groove 420 is used to provide an insertion point when the inner swivel 300 is locked, so that the protrusion 510 of the dial button 500 can be inserted into it, thereby limiting the rotation of the outer swivel 400. When the inner swivel 300 is not in the locked position, the locking groove 420 and the second escape groove 132 are offset. Only when the inner swivel 300 is in the locked position, the locking groove 420 and the second escape groove 132 are aligned and connected.

[0047] In the example, when the inner rotating ring 300 is in the locked position, the position of the outer rotating ring 400 is such that the locking groove 420 communicates with the lower part of the second clearance groove 132. This means that the protruding part 510 can slide into the lower part of the second clearance groove 132 and be embedded in the locking groove 420. At this time, the protruding part 510 catches the outer rotating ring 400 and restricts its rotation to lock the inner rotating ring 300 in the locked position; when the dial 500 is in the free position, the outer rotating ring 400 can rotate freely after losing the restraint of the protruding part 510. When the inner rotating ring 300 is not in the locked position, the upper edge surface of the outer rotating ring 400 abuts against the protruding part 510, thereby restricting the dial 500 in the free position, that is, the dial 500 cannot be toggled downward.

[0048] Through the design of the dial 500 and the locking groove 420, a dual locking mechanism is provided, that is, the outer rotating ring 400 can be locked through the dial 500, so that the inner rotating ring 300 can be locked when in the locked position, further increasing the safety of the cup lid and preventing the flip cover 200 from accidentally opening. During actual operation, the user only needs to slide the dial 500 to lock and unlock the outer rotating ring 400.

[0049] On the basis of the above embodiments, two parallel gear positions grooves 320 are provided on the outer peripheral surface of the inner rotating ring 300. The back surface of the dial 500 is attached to the outer peripheral surface of the inner rotating ring 300. A gear position block 520 is provided on the back surface of the dial 500. When the dial 500 is in the safety position, the gear position block 520 is located in one gear position groove 320, and when the dial 500 is in the free position, the gear position block 520 is located in the other gear position groove 320.

[0050] The main function of the two gear position grooves 320 is to ensure that the dial 500 can be stably fixed in the corresponding position at different stroke positions (safety position and free position). When the dial 500 slides to the safety position, the gear position block 520 on the back surface of the dial 500 will be embedded in one gear position groove 320 to ensure that the dial 500 will not accidentally slide back to the free position. This can effectively prevent the accidental rotation of the outer rotating ring 400, thereby maintaining the locked state of the inner rotating ring 300. When the dial 500 slides to the free position, the gear position block 520 on the back surface of the dial 500 will be embedded in the other gear position groove 320 to ensure that the dial 500 will not accidentally slide back to the safety position. This allows the outer rotating ring 400 to rotate freely, thereby unlocking the inner rotating ring 300. When the outer rotating ring 400 drives the inner rotating ring 300 to twist, the gear position groove 320 and the gear position block 520 can move relative to each other to avoid stroke interference.

[0051] Such as Figures 1-5As shown, based on the above-described embodiment, an opening groove 160 communicating with the annular mounting cavity 140 is formed at the top of the cover base 100, and a buckle base 210 is provided on the flip cover 200. When the flip cover 200 is in the closed position, the buckle base 210 is inserted into the annular mounting cavity 140 through the opening groove 160 and buckled with the locking buckle 310. The opening groove 160 ensures that when the flip cover 200 is closed, the buckle base 210 can be smoothly inserted into the annular mounting cavity 140 so as to be buckled with the locking buckle 310.

[0052] As Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 As shown, based on the above-described embodiment, a fixing bracket 150 located in the annular mounting cavity 140 is provided on the cover base 100, and an elastic member is installed between the inner rotating ring 300 and the fixing bracket 150. The elastic member applies an elastic force to the inner rotating ring 300 to make it rotate towards the locking position.

[0053] The elastic member applies an elastic force to the inner rotating ring 300 to make it rotate towards the locking position. After the inner rotating ring 300 is twisted to the locking position through the outer rotating ring 400, the flip cover 200 can be directly covered. The buckle base 210 on the flip cover 200 is inserted into the annular mounting cavity 140 through the opening groove 160 and pushes the locking buckle 310. At this time, the inner rotating ring 300 will retreat to allow the buckle base 210 to be inserted into the set position. When the buckle base 210 is in place, the elastic force applied by the elastic member to the inner rotating ring 300 causes the inner rotating ring 300 to return to the locking position again. At this time, the locking buckle 310 on the inner rotating ring 300 buckles the buckle base 210. Through the above design, when the flip cover 200 rotates to the closed position, the locking buckle 310 and the buckle base 210 can be automatically buckled together to lock the flip cover 200.

[0054] As Figures 1-9 As shown, based on the above-described embodiment, a cup includes a cup lid, and further includes a cup body 600. The cover base 100 of the cup lid is connected to the cup body 600. In an actual structure, internal threads are formed on the inner peripheral surface of the inner peripheral wall 120, external threads are provided at the edge of the cup body 600, and the edge of the cup body 600 is connected to the inner peripheral wall 120 so that the two are connected.
