[0038] like Figures 1-5As shown in the first embodiment of this utility model, a locking cup lid is provided, including a lid body 100, a lid body 300, and a handle ring 200. The lid body 100 can be connected to the cup body, and a first drinking spout 101 is provided on the lid body 100. The rear side of the first upper cover 300 is rotatably connected to the rear side of the lid body 100, and the front side is locked to the front side of the lid body 100 through a locking structure. The first upper cover 300 can rotate between a first position blocking the first drinking spout 101 and a second position opening the first drinking spout 101. A first fastening member 303 is provided on the outer side wall of the first upper cover 300. The two rear ends of the handle ring 200 are rotatably connected to the lid body 100 and the rear side of the first upper cover 300, respectively, and can rotate between a locked position relative to the lid body 100 and an unlocked position relative to the lid body 100. A second fastening member 230 is provided on the inner side wall of the handle ring 200, corresponding to the first fastening member 303. The locking cup lid of this embodiment can, when the first upper cover 300 is in the first position and the handle 200 is in the locked position, engage with the second fastening member 230 on the inner side wall of the handle 200 and the first fastening member 303 on the outer side wall of the first upper cover 300 to prevent the first upper cover 300 from rotating to the second position where the first drinking spout 101 is open. This prevents the first drinking spout 101 from being accidentally opened due to collisions with external objects, thus improving safety during carrying. Simultaneously, the handle 200 can function as a handle for carrying the locking cup lid or the cup as a whole when in the unlocked position, and as a safety lock to prevent the first upper cover 300 from being opened when in the locked position, offering multiple uses and high practicality. In other embodiments, the two rear ends of the handle 200 can be rotatably connected only to the rear side of the lid body 100, or only rotatably connected to the rear side of the first upper cover 300, both allowing rotation relative to the lid body 100.

[0039] like Figure 2As shown, in some specific embodiments, the first fastening member 303 has a first fastening surface arranged on its upper side, and the second fastening member 230 has a second fastening surface arranged on its lower side. When the first upper cover 300 is in the first position and the handle ring 200 is in the locked position, the second fastening surface blocks the upper side of the first fastening surface to prevent the first upper cover 300 from rotating to the second position. In this embodiment, the first fastening member 303 and the second fastening member 230 are respectively configured as elongated structures, and the first fastening surface and the second fastening surface are respectively configured as strip-shaped surfaces. When the second fastening surface blocks the upper side of the first fastening surface, the first fastening surface and the second fastening surface make surface-to-surface contact, which increases the contact area between the first fastening surface and the second fastening surface, improves the stability of the mutual fastening of the first fastening member 303 and the second fastening member 230, and can more stably and effectively prevent the first upper cover 300 from rotating to the second position. Of course, in other embodiments, the first fastening member 303 or the second fastening member 230 can also be configured as a protrusion structure, so that when the second fastening surface blocks the upper side of the first fastening surface, the first fastening surface and the second fastening surface make point-to-surface contact, which can also prevent the first upper cover 300 from rotating to the second position.

[0040] like Figure 3 As shown, in some specific embodiments, the cover body 100 includes a cover base 110, a mounting base 120 and a rotating base 130 protruding from the upper side of the cover base 110. When the handle ring 200 is in the locked position, it is arranged around the outer periphery of the mounting base 120. When the first upper cover 300 is in the first position, it abuts against the upper side of the mounting base 120, resulting in a compact structure. The rotating base 130 is arranged at the rear of the mounting base 120. The rotating base 130 is rotatably connected to the rear of the first upper cover 300 and the two rear ends of the handle ring 200 via a rotating shaft 800. This allows the first upper cover 300 to rotate relative to the rotating base 130 and the handle ring 200 via the rotating shaft 800, and the handle ring 200 to rotate relative to the rotating base 130 and the first upper cover 300 via the rotating shaft 800. Furthermore, the rotating base 130, the first upper cover 300, and the handle ring 200 share the same rotating shaft 800, resulting in a simple structure and convenient assembly. Furthermore, the rotating shaft 800 and the mounting base 120 are located on the same horizontal plane, ensuring that the handle 200 can be horizontally arranged around the outer periphery of the mounting base 120 when it is in the locked position, reducing the space occupied by the handle 200 and facilitating storage and carrying. Of course, in other embodiments, a rotating shaft can also be provided between the first upper cover 300 and the rotating base 130, between the handle 200 and the rotating base 130, or between the handle 200 and the first upper cover 300, to achieve a rotatable connection between the rotating base 130, the first upper cover 300, and the handle 200.

[0041] like Figure 3As shown, in some specific embodiments, the first upper cover 300 includes a first side cover plate 310, a first top cover plate 320 connected to the top of the first side cover plate 310, and connectors 330 respectively arranged on both sides of the rotating base 130. The two rear ends of the handle ring 200 are respectively arranged on the side of the two connectors 330 away from the rotating base 130. When the first upper cover 300 is in the first position, the lower edge of the first side cover plate 310 abuts against the upper side of the mounting base 120. The first fastening member 303 is arranged along the lower edge of the outer side wall of the first side cover plate 310 in front of the connector 330. When the first upper cover 300 is in the first position and the handle ring 200 is in the locked position, the second fastening surface blocks the first fastening surface to prevent the first upper cover 300 from rotating backward relative to the cover body 100 to the second position via the rotating shaft 800. In this embodiment, the height of the first top cover plate 320 relative to the cover body 100 gradually decreases from front to back. The connector 330 is connected to both the first side cover plate 310 and the first top cover plate 320, resulting in better connection stability. In other embodiments, the connector 330 may be connected to only one of the first side cover plate 310 and the first top cover plate 320. The two connectors 330 each have a first rotation channel 331 corresponding to the rotation shaft 800. The two rear ends of the handle ring 200 each have a second rotation channel 260 corresponding to the rotation shaft 800. A third rotation channel 131 is provided through the rotating base 130. The third rotation channel 131, the first rotation channels 331, and the second rotation channels 260 are arranged on the same straight line. The rotation shaft 800 passes sequentially through the third rotation channel 131, the first rotation channels 331, and the second rotation channels 260, so that the cover body 100, the first top cover 300, and the handle ring 200 are rotatably connected to each other.

[0042] In some specific embodiments, the rotating shaft 800 includes a rotating shaft rod 820 and a limiting rod 830. One end of the rotating shaft rod 820 has a first end head 821 protruding radially, and the other end has a connecting channel 822 recessed axially. One end of the limiting rod 830 has a second end head 831 protruding radially, and the other end is inserted into the connecting channel 822 to cooperate with the rotating shaft rod 820. This cooperation connection can be a threaded connection, a snap-fit ​​connection, or a riveting connection, or other methods. The outer diameter of the first end head 821 and the second end head 831 is larger than the outer diameter of the second rotating channel 260, so that the two rear ends of the handle ring 200 are respectively limited to the inner sides of the first end head 821 and the second end head 831. The handle 200 has recessed grooves 270 formed on its outer side at both ends to accommodate the first end head 821 and the second end head 831, so that the first end head 821 and the second end head 831 are flush or nearly flush with the outer surface of the handle 200. The structure is compact, which further reduces the space occupied by the overall structure of the locking cup lid, making it convenient to store and carry. In addition, the first end head 821 and the second end head 831 are stored in the recessed grooves 270, which can also prevent fingers from being pinched.

[0043] like Figure 2 As shown, in some specific embodiments, the first side cover 310 includes a first side cover body 311 and first side cover extensions 312 extending downward from the lower edges of both sides of the first side cover body 311. The two first side cover extensions 312 are respectively connected to the front of the two connectors 330. The outer walls of both sides of the mounting base 120 are respectively recessed from their top to the bottom to accommodate the corresponding first side cover extensions 312. Two first fasteners 303 are provided. The two first fasteners 303 protrude from the outer walls of the two first side cover extensions 312 toward the outside of the mounting base 120, so that the structure of the first top cover 300 and the cover body 100 is compact. The connection strength between the connectors 330 and the first side cover body 311 is strengthened by the first side cover extensions 312, making the structure of the first top cover 300 more robust and durable.

[0044] In some specific embodiments, there are two second fastening members 230 corresponding to the first fastening member 303. The inner walls on both sides of the handle ring 200 are respectively provided with guide grooves 240 from the bottom upwards. The two second fastening members 230 are respectively formed by the upper side walls of the two guide grooves 240. When the handle ring 200 and the first upper cover 300 rotate relative to each other, the first fastening member 303 can move along the guide groove 240 to fasten or separate from the second fastening member 230. In this embodiment, the two second fastening members 230 are respectively formed by the upper sidewalls of the two guide grooves 240. Compared with the guide grooves 240 protruding from the inner sidewall of the handle ring 200, when the first fastening member 303 and the second fastening member 230 are fastened together, the first fastening member 303 can be stored in the guide groove 240. This reduces the gap width between the handle ring 200 and the outer peripheral sidewall of the mounting base 120, making the structure of the handle ring 200 and the mounting base 120 more compact when the handle ring 200 is in the locked position. This reduces the overall width of the locking cup lid structure, making it easier to store and carry.

[0045] In some specific embodiments, the outer diameter of the mounting base 120 is smaller than the outer diameter of the cover base 110, so that a storage area for storing the handle ring 200 is formed between the outer side of the mounting base 120 and the upper side of the cover base 110. A third fastening member 122 protrudes from the outer side wall of the mounting base 120, and a fourth fastening member 250 protrudes from the inner side wall of the handle ring 200. The handle ring 200 abuts against the lower side of the third fastening member 122 through the fourth fastening member 250, and the lower edge of the handle ring 200 abuts against the upper side of the cover base 110 to lock in the locked position. When the operator applies a certain force upward to the handle ring 200, the fourth fastening member 250 can be moved past the third fastening member 122 and rotated to the unlocked position.

[0046] like Figure 4As shown, in some specific embodiments, the locking structure is configured as a button 500. The button 500 includes a button connecting portion 510, a button trigger portion 520 connected to the button connecting portion 510, and a first locking portion 530 connected to the button connecting portion 510. The button connecting portion 510 is movably connected to the front side of the cover body 100 in the front direction. The front side of the first upper cover 300 is provided with a second locking portion 302 corresponding to the first locking portion 530. The button 500 can move between a latched position where the first locking portion 530 and the second locking portion 302 are engaged and a latched position where the first locking portion 530 and the second locking portion 302 are disengaged. The first upper cover 300 is held in a first position by the engagement of the first locking portion 530 and the second locking portion 302. When button 500 is in the unlocked position, the first locking part 530 and the second locking part 302 separate, allowing the first upper cover 300 to be in the second position. A first reset member 540 is provided between the button connecting part 510 and the cover body 100 to maintain button 500 in the latched position. The first reset member 540 is a structure such as a compression spring or elastic silicone that provides elastic force. After the pressure on button 500 is released, the button 500 automatically resets to the latched position under the elastic force of the first reset member 540, facilitating the next press of button 500. A second reset member 810 is provided between the rear side of the first top cover 300 and the rear side of the cover body 100 to keep the first top cover 300 in the second position. The second reset member 810 is a structure that can provide elastic force, such as a torsion spring or rubber band. After the squeeze button 500 moves from the latch position to the unlock position, the first top cover 300 can be automatically opened to the second position under the elastic force of the second reset member 810, so as to facilitate quick opening of the first drinking spout 101 for drinking.

[0047] like Figure 3 , Figure 4As shown, in some specific embodiments, a button groove 124 is recessed on the front side of the mounting base 120, and the rear part of the button 500 is arranged in the button groove 124 to reduce the gap width between the inner sidewall of the front part of the handle ring 200 and the front sidewall of the mounting base 120, making the structure of the handle ring 200 and the cover body 100 more compact and convenient for storage and carrying. The first locking part 530 includes a first connecting block 531 protruding longitudinally from the upper side of the button connecting part 510 and a first locking block 532 protruding from the front side of the first connecting block 531. The second locking part 302 is configured as a groove structure recessed from the inner sidewall of the front sidewall of the first upper cover 300, and the front side of the first upper cover 300 and the front side of the cover body 100 are locked together by the first locking block 532 extending into the second locking part 302. Guide blocks 511 are protruding on both sides of the button connection part 510. Guide grooves 1241 are opened on both sides of the button groove 124 along the pressing direction of the button 500. When the button 500 is pressed, the guide blocks 511 are inserted into the guide grooves 1241 and slide along the guide grooves 1241 to guide the button, thereby improving the stability of the button 500.

[0048] like Figure 4 As shown, in some specific embodiments, a limiting structure 140 is assembled at the bottom of the button slot 124. The limiting structure 140 includes a limiting body 141, a second connecting block 142 protruding longitudinally from the upper side of the limiting body 141, and limiting blocks 143 protruding from both sides of the second connecting block 142. The bottom wall of the button slot 124 has an assembly channel 1242 for the second connecting block 142 to pass through. The limiting structure 140 and the button slot 124 are assembled by fastening the bottom wall of the button slot 124 between the lower side of the limiting block 143 and the upper side of the limiting body 141, which facilitates production assembly. The bottom of the button connection part 510 is recessed and a limiting groove 512 is arranged along the pressing direction of the button 500. The limiting block 143 is arranged in the limiting groove 512 to prevent the button 500 from disengaging from the cover body 100. When the button 500 slides along the guide groove 1241, the limiting block 143 moves in the limiting groove 512 to ensure that the button 500 can move backward from the latch position to the unlock position.

[0049] like Figure 1As shown, in some specific embodiments, a constraint channel 210 is provided through the front end of the handle 200 in the front-back direction. When the handle 200 is in the locked position, the constraint channel 210 is arranged correspondingly to the button 500, so as to prevent the button 500 from being squeezed from outside the constraint channel 210 to move backward from the latched position to the unlocked position, but not to prevent the button 500 from being squeezed through the constraint channel 210 to move backward from the latched position to the unlocked position. In this embodiment, by providing a constraint channel 210 extending through the front end of the handle 200 in the front-back direction, when the handle 200 is in the locked position, it can prevent objects larger than the constraint channel 210 from pressing the button 500 from the latched position to the unlocked position. This, in addition to preventing the first upper cover 300 from rotating to the second position where the first drinking spout 101 is opened, is further prevented from accidentally opening the first upper cover 300 due to collision with objects larger than the constraint channel 210. This provides dual protection and further enhances safety during carrying. It also allows operators to use their fingers or other parts of their body narrower than the restraint channel 210 to squeeze the button 500 from the latched position to the unlocked position. Operators can insert their fingers into the restraint channel 210 and reliably lift the handle 200 from the locked position to the unlocked position. Even if the button 500 is squeezed from the latched position to the unlocked position while the operator's fingers are inside the restraint channel 210, the second fastener 230 and the first fastener 303 can engage to prevent the first top cover 300 from rotating to the second position, thus preventing accidental activation of the button 500.

[0050] In some specific embodiments, the constraint channel 210 allows the operator's fingertips to pass through when the handle 200 is in the locked position. The constraint channel 210 has a width of 10mm to 25mm and a depth of 1mm to 10mm, which can prevent common foreign objects from squeezing the button 500, reducing the risk of accidental squeezing of the button 500, while ensuring that the operator's fingertips can pass through the constraint channel 210. In this embodiment, the width of the constraint channel 210 can be set to 15mm~20mm, especially 16mm, 17mm, 18mm or 19mm, which is more suitable for the width of people's fingertips. This can better ensure the comfort of the operator when the fingertips can pass through the constraint channel 210 while blocking some common foreign objects from squeezing the button 500. The depth of the constraint channel 210 is 2mm~6mm, especially 3mm, 4mm or 5mm, which is more suitable for the depth of people's fingertips and can better prevent the sharp corners of some foreign objects from passing through the constraint channel 210 and squeezing the button 500 from the latched position to the unlocked position.

[0051] like Figure 1 As shown, in some specific embodiments, the peripheral sidewall of the constraint channel 210 is configured as a semi-closed structure with a lower opening. When the handle 200 is in the locked position and the button 500 is in the latched position, the button trigger part 520 is arranged inside the constraint channel 210. The button trigger part 520 can extend into or out of the constraint channel 210 from the lower opening, so that the handle 200 can rotate between the locked position and the unlocked position when the button 500 is in the latched position, avoiding interference from the button 500 to the rotation of the handle 200. That is, when the first cover 300 is in the first position, the operator can operate the handle 200 to rotate between the locked position and the unlocked position, so that the handle 200 can be rotated from the locked position to the unlocked position first, and then the button 500 can be opened by the fingers or other parts, so that the first cover 300 can be rotated from the first position of blocking the first drinking mouth 101 to the second position of opening the first drinking mouth 101, so as to open the first drinking mouth 101 for drinking. Meanwhile, when the handle ring 200 is in the locked position and the button 500 is in the latched position, the squeezing motion of the external object on the button trigger part 520 is interfered with by the constraint channel 210 and the handle ring 200 around the constraint channel 210, and cannot move backward a long distance through the constraint channel 210 to move the button 500 from the latched position to the unlocked position. This further prevents the button 500 from accidentally opening the first top cover 300 due to collision with some external objects that are wider than the constraint channel 210.

[0052] like Figure 2As shown, in some specific embodiments, the button trigger portion 520 has a front side and a peripheral side connecting the front side of its front side and the front side of the button connection portion 510. The peripheral sidewall of the constraint channel 210 is configured to match the shape of the peripheral side of the button trigger portion 520. When the handle ring 200 is in the locked position and the button 500 is in the latched position, the front side of the button trigger portion 520 is flush with the front side of the handle ring 200, and the peripheral side of the button trigger portion 520 abuts against or is spaced from the peripheral sidewall of the constraint channel 210, thereby reducing the gap between the peripheral side of the button trigger portion 520 and the peripheral sidewall of the constraint channel 210, avoiding the accumulation of impurities, and making the structure of the button trigger portion 520 and the handle ring 200 more compatible, and the outer surface of the locking cup lid is flatter and more beautiful. The constraint channel 210 is configured as a 1 / n circular channel, and the button trigger part 520 is configured as a 1 / n circular structure that matches the constraint channel 210. This better adapts to the shape of the operator's fingertips and does not interfere with the rotation of the handle ring 200 between the locked and unlocked positions. In this embodiment, n=2, that is, the constraint channel 210 is configured as a semi-circular channel, and the button trigger part 520 is configured as a semi-circular structure, which has a larger contact surface with the operator's fingertips. This results in higher comfort when the fingertips squeeze the button trigger part 520. In other embodiments, n>2 can also be configured to enhance the stability of the handle ring 200 structure.

[0053] like Figure 3As shown, in some specific embodiments, a second upper cover 400 and a second drinking spout 301 are also included. A water passage 102 is provided on the cover body 100. The second drinking spout 301 is disposed on the drinking spout of the first upper cover 300 and can communicate with the water passage 102. The second upper cover 400 is configured to selectively cover the second drinking spout 301. The second upper cover 400 can move between a third position where the second drinking spout 301 is covered and a fourth position where the second drinking spout 301 is uncovered. That is, when the second upper cover 400 is in the third position, the second drinking spout 301 is closed, and drinking cannot be done through the second drinking spout 301. When the second upper cover 400 is in the fourth position, the second drinking spout 301 is open, and drinking can be done through the second drinking spout 301. When the handle 200 is in the locked position, the button 500 is in the latched position, and the second upper cover 400 is in the third position, the handle 200 is positioned below the second upper cover 400 to allow the second upper cover 400 to move between the third and fourth positions. This allows the operator to move the second upper cover 400 from the third to the fourth position when the first upper cover 300 is in the first position and the handle 200 is in the locked position, facilitating quick opening of the second drinking spout 301 for drinking. Furthermore, while drinking through the second drinking spout 301, the handle 200 also helps prevent accidental activation of the button 500, thus improving safety during use. In this embodiment, two drinking spouts are provided, allowing the operator to choose between the first drinking spout 101 and the second drinking spout 301 for drinking, offering greater versatility.

[0054] In some specific embodiments, a drinking spout 600 protrudes from the upper side of the cover body 100 around the first drinking opening 101, and the drinking spout 600 is integrally formed with the mounting base 120. A water passage 102 is arranged on the rear side of the drinking spout 600. The drinking spout on the first upper cover 300 is set as a sippy spout 700, which is rotatably connected to the first upper cover 300. The second drinking opening 301 is provided through the sippy spout 700, and the water passage 102 is connected to a straw for extending into the cup body, allowing the operator to drink the beverage in the cup body through the sippy spout 700. The spout 700 has a retracted state relative to the first top cover 300 and an unfolded state relative to the first top cover 300. When the first top cover 300 is in the first position and the spout 700 is in the retracted state, the spout 700 blocks the water passage 102, preventing the beverage in the cup from flowing out from the water passage 102 or the second drinking spout 301. When the first top cover 300 is in the first position and the spout 700 is in the unfolded position, the second drinking spout 301 is connected to the water passage 102, allowing the beverage in the cup to flow into the operator's mouth through the straw, water passage 102, and second drinking spout 301. In other embodiments, the spout 700 can also be configured as a soft straw structure or a direct drinking spout structure, and can be fixed relative to the first top cover 300, allowing drinking through the second drinking spout 301.

[0055] In some specific embodiments, the mounting base 120 has a recessed platform 123 along its upper edge. When the first upper cover 300 is in the first position, the bottom of the first upper cover 300 is positioned within the recessed platform 123 to limit its movement, thereby improving the stability of the first upper cover 300 in the first position. Furthermore, the outer surface of the first upper cover 300 is flush with or substantially flush with the side surface of the mounting base 120 to avoid interference with the rotation of the handle 200. This ensures that the handle 200 can rotate outside the first upper cover 300 while maximizing the width of the first upper cover 300, thus providing ample space for the drinking spout 600 and the sipping nozzle 700.

[0056] In some specific embodiments, the top of the first upper cover 300 is recessed with a storage groove 350 for accommodating the spout 700. The spout 700 includes a rotating part 710 and a spout portion 720 connected to the rotating part 710. The rotating part 710 is rotatably connected within the storage groove 350, and the second upper cover 400 is rotatably connected to the outside of the spout portion 720. The second upper cover 400 includes a second side cover plate 410 that can cover the outside of the second drinking spout 301, and a second top cover plate 420 that can cover the upper side of the spout portion 720, for dust prevention and protection of the spout portion 720. When in the stored state, the spout 700 can be accommodated within the storage groove 350, reducing the space occupied by the first upper cover 300, making the overall structure of the locking cup lid compact, occupying little space, and convenient for storage and carrying. The outer side of the second side cover 410 is recessed to form a lever groove 411 for the operator to open the second upper cover 400. The operator can rotate the second upper cover 400 relative to the nozzle 720 through the lever groove 411, thereby further rotating the nozzle 700 relative to the first upper cover 300 to the unfolded state. In this embodiment, when the nozzle 700 is housed in the storage groove 350, the outer surfaces of the nozzle 700 and the second upper cover 400 are flush or substantially flush with the outer surface of the first upper cover 300, thereby minimizing the space occupied by the overall structure of the locking cup lid. In other embodiments, the nozzle 700 may also be configured to protrude from the surface of the first upper cover 300 when in the stored state. In other embodiments, the second upper cover 400 may also be rotatably connected to the first upper cover 300.

[0057] In some specific embodiments, a pressure relief channel 103 is also provided through the cover body 100. The pressure relief channel 103 is arranged between the drinking spout 600 and the water passage 102. When the first upper cover 300 is in the first position and the spout 700 is in the retracted state, the spout 700 blocks the water passage 102 and the pressure relief channel 103. When the first upper cover 300 is in the first position and the spout 700 is in the unfolded state, the spout 700 opens the pressure relief channel 103 and the first drinking spout 101 is connected to the water passage 102. In this embodiment, the pressure relief channel 103 is open during both direct drinking and sipping. The pressure relief channel 103 allows the gas inside the cup to circulate with the outside gas to balance the internal and external air pressure, improving the smoothness of direct drinking and sipping, making it convenient and easy to drink. When the first top cover 300 is in the first position and the spout 700 is in the storage state, the first top cover 300 covers the first drinking mouth 101, and the spout 700 blocks the water passage 102 and the pressure relief channel 103 to prevent water leakage, making it convenient to carry around.

[0058] In some specific embodiments, the rotating part 710 includes a wheel 711 and a sealing body 712 arranged on the front side of the wheel 711. The first upper cover 300 is provided with an opening 360, which communicates with the storage groove 350. When the first upper cover 300 is in the first position and the mouthpiece 700 is in the stored state, the rotating part 710 extends through the lower side of the opening 360 so that the wheel 711 presses against and blocks the water passage 102, and the sealing body 712 presses against and blocks the pressure relief passage 103. When the first upper cover 300 is in the first position and the mouthpiece 700 is in the unfolded state, the sealing bodies 712 are arranged at intervals above the opening 360 to form an airflow channel communicating with the outside between the opening 360 and the pressure relief passage 103, so that the air inside the cup can circulate with the outside air to balance the internal and external air pressure when drinking.

[0059] In some specific embodiments, a flexible sealing element for sealing the first drinking spout 101 is installed at the bottom of the first upper cover 300. When the first upper cover 300 is in the first position, the first drinking spout 101 is squeezed and deformed to seal the first drinking spout 101, resulting in good sealing performance. The cover body 100 also includes a flexible connector 150 installed on the upper side of the cover base 110. The water passage 102 and the pressure relief passage 103 are disposed through the flexible connector 150 and the cover base 110. The wheel 711 seals the water passage 102 by squeezing and deforming the flexible connector 150, and the sealing body 712 seals the pressure relief passage 103 by squeezing and deforming the flexible connector 150, resulting in good sealing performance.

[0060] like Figure 5 As shown, in some specific embodiments, the first top cover 300 is configured with a triangular cross-section. The three sides of the triangle are the first side A, the second side B, and the base C. The lengths of the first side A and the second side B are respectively less than the length of the base C, and the length of the first side A is less than the length of the second side B. The first side A is arranged on the front side of the first top cover 300, the second side B is arranged on the upper side of the first top cover 300, and the drinking spout 600 is arranged close to the first side A. When the first top cover 300 is in the first position and the spout 700 is in the retracted state, the spout 700 is arranged along the length direction of the second side B, and the spout part 720 is arranged on the upper side of the drinking spout 600, the rotating part 710 is arranged on the rear side of the drinking spout 600, the second top cover plate 420 is arranged along the length direction of the second side B, and the second side cover plate 410 is arranged along the length direction of the first side A. In this embodiment, the arrangement of the spout 700 makes full use of the empty space next to the drinking spout 600, resulting in a compact overall structure. This further reduces the space occupied by the locking cup lid structure, making it more convenient to store and carry. When the handle 200 is in the unlocked position, a lifting space is formed between the inner side of the handle 200 and the second side B, providing a larger gripping area for easy and comfortable carrying.

[0061] In some specific embodiments, the inner wall of the mounting base 120 is provided with a threaded structure for connection with the cup body, facilitating disassembly and cleaning. In other embodiments, the threaded structure may also be provided on the inner wall of the cover base 110, or on the outer wall of the mounting base 120 or the cover base 110, both of which allow for detachable connection with the cup body.

[0062] like Figure 6 As shown, as a second embodiment of this utility model, a locking cup lid is also provided. The main difference between the second embodiment and the first embodiment is that the peripheral wall of the constraint channel 210 is set as a fully enclosed structure, that is, the peripheral wall of the constraint channel 210 has no opening, thereby ensuring the stability of the overall structure of the handle ring 200. When the handle ring 200 is in the locked position and the button 500 is in the latched position, the entire structure of the button 500 is arranged on the rear side of the constraint channel 210, so that the handle ring 200 can rotate between the locked position and the unlocked position when the button 500 is in the latched position, avoiding interference from the button 500 to the rotation of the handle ring 200. That is, when the first cover 300 is in the first position, the operator can first rotate the handle ring 200 from the locked position to the unlocked position, and then use a finger or other part to open the button 500, so that the first cover 300 can rotate from the first position of blocking the first drinking spout 101 to the second position of opening the first drinking spout 101, so as to open the first drinking spout 101 for drinking.

[0063] In some specific embodiments, the button trigger portion 520 protrudes from the front side of the button connection portion 510. When the handle ring 200 is in the locked position and the button 500 is in the latched position, the distance between the front side of the button trigger portion 520 and the rear side of the constraint channel 210 is less than the distance between the front side of the button connection portion 510 and the rear side of the constraint channel 210. This shortens the depth to which the operator's fingertip can be inserted into the constraint channel 210 when it passes through the constraint channel 210, thus preventing the finger from being excessively inserted into the constraint channel 210 and getting stuck inside.

[0064] In some specific embodiments, the constraint channel 210 is configured as an elliptical channel, which better adapts to the shape of the operator's fingertips, further improving the comfort of the operator's fingertips when passing through the constraint channel 210. It also provides greater protection against foreign objects passing through the constraint channel 210 and pressing the button 500 from the latched position to the unlocked position. The button trigger portion 520 is configured as an elliptical structure that matches the constraint channel 210, improving the comfort of the operator's fingertips when pressing the button trigger portion 520. Of course, in other embodiments, the constraint channel 210 can also be configured as a circular channel, square channel, triangular channel, heart-shaped channel, flower-shaped channel, or other shapes, and the button trigger portion 520 can also be configured as a shape that matches or does not match the constraint channel 210.

[0065] like Figure 7 As shown, as a third embodiment of the present invention, a locking cup lid is also provided. The main difference between the third embodiment and the second embodiment is that the front side of the button trigger part 520 is recessed relative to the front side of the button connecting part 510. When the handle ring 200 is in the locked position and the button 500 is in the latched position, the distance between the front side of the button trigger part 520 and the rear side of the constraint channel 210 is less than the distance between the front side of the button connecting part 510 and the rear side of the constraint channel 210. Compared to the first embodiment, the second embodiment increases the distance between the front side of the button trigger portion 520 and the rear side of the constraint channel 210. This allows the outer side of the handle ring 200, the constraint channel 210, and the area between the front side of the button trigger portion 520 and the rear side of the constraint channel 210 to collectively form an anti-accidental contact protection area to prevent foreign objects from accidentally squeezing the button 500 from the latched position to the unlocked position. This further prevents the slender, sharp corners of some foreign objects from passing through the constraint channel 210 and squeezing the button 500 from the latched position to the unlocked position, thus providing a wider range of protection against foreign objects passing through the constraint channel 210 and squeezing the button 500 from the latched position to the unlocked position, further improving the safety of carrying a cup with the locking lid. Furthermore, in this embodiment, the front side of the button trigger portion 520 is designed with a concave arc surface structure, which is more compatible with the shape of the operator's fingertips, improving comfort when squeezing the button trigger portion 520 with the fingertips. In other embodiments, the front side of the button trigger portion 520 and the front side of the button connection portion 510 may also be flush. When the handle ring 200 is in the locked position and the button 500 is in the latched position, the distance between the front side of the button trigger portion 520 and the rear side of the constraint channel 210 is equal to the distance between the front side of the button connection portion 510 and the rear side of the constraint channel 210, which can also improve the safety of carrying a cup with the locking cup lid.

[0066] like Figure 8As shown, as a fourth embodiment of this utility model, a locking cup lid is also provided. The main difference between the fourth embodiment and the second embodiment is that an elastic structure 220 is installed inside the constraint channel 210. When the handle 200 is in the locked position and the button 500 is in the latched position, the entire structure of the button 500 is arranged on the rear side of the constraint channel 210, allowing the handle 200 to rotate between the locked and unlocked positions when the button 500 is in the latched position. Furthermore, the elastic structure 220 prevents foreign objects from entering the constraint channel 210, thus squeezing the button 500 from the latched position to the unlocked position, further improving safety during carrying. The elastic structure 220 is made of an elastic material capable of a certain degree of deformation, improving the comfort of the operator when inserting their fingers into the constraint channel 210 to stably lift the handle 200 upwards.

[0067] In other embodiments, the button 500 has a first region located behind the constraint channel 210 of the handle 200 in the locked position, and a second region located under the cover of the handle 200 in the locked position. In the locked position, the handle 200 prevents operation of the second region of the button, thereby preventing external objects from accidentally opening the first drinking spout 101 and improving safety during carrying. The first region, located inside or behind the constraint channel 210, further prevents external objects larger than the constraint channel 210 from pressing against the first region from outside the constraint channel 210, causing the button 500 to move rearward from the latched position to the unlocked position when the handle 200 is in the locked position. This prevents the button 500 from accidentally opening the first drinking spout 101 due to collision with external objects larger than the constraint channel, further improving safety during carrying.

[0068] like Figure 9 As shown, as the fifth embodiment of this utility model, a locking cup lid is also provided. The main difference between the fifth embodiment and the first embodiment is that the constraint channel 210 is eliminated, so that when the handle 200 is in the locked position, it can be engaged with the first fastening member 303 on the outer side wall of the first cover 300 through the second fastening member 230 on the inner side wall of the handle 200, so as to prevent the first cover 300 from rotating to the second position of opening the first drinking spout 101. Furthermore, the front wall of the handle 200 blocks the front side of the button 500 to prevent the button 500 from being accidentally opened by the collision of external objects, thereby achieving double protection and further improving the safety during carrying.

[0069] like Figure 10As shown, in the sixth embodiment of this utility model, a cup is also provided, including a cup body 900 with a receiving cavity and a locking lid as in the first embodiment connected to the cup body 900. Because the cup in this embodiment is equipped with the locking lid provided by this utility model, it can also prevent the button 500 from being accidentally opened by external impact. In other embodiments, the locking lid can also be the locking lid provided in the second, third, fourth, fifth, and sixth embodiments, all of which can prevent the button 500 from being accidentally opened by external impact.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.

[0071] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
