[0031] As Figure 1 and Figure 2 shown, the present invention discloses a lock piece cup cover 100. The cup cover 100 includes a bottom cover 10, an upper cover 20 and a locking mechanism 30. A water port 11 is provided on the bottom cover 10. The upper cover 20 is rotatably connected to the bottom cover 10, and the water port 11 on the bottom cover 10 can be opened or sealed by the upper cover 20. When the upper cover 20 seals the water port 11 on the bottom cover 10, the upper cover 20 can be locked by the locking mechanism 30 to prevent the upper cover 20 from rotating relative to the bottom cover 10.

[0032] As Figure 2 and Figure 3 shown, the upper cover 20 is provided with a first sealing groove 21. When the upper cover 20 seals the water port 11 of the bottom cover 10, the water port 11 extends into the first sealing groove 21 and abuts against the first sealing gasket 23 in the first sealing groove 21 to achieve the sealing of the water port 11.

[0033] The first sealing gasket 23 is made of silica gel material.

[0034] The upper cover 20 includes a connecting portion 22. One end of the connecting portion 22 is connected to the first sealing groove 21, and the other end of the connecting portion 22 is rotatably connected to the bottom cover 10 through a rotating shaft. A handle 40 is also rotatably connected to the rotating shaft, and a handle ring is provided on the handle 40.

[0035] The locking mechanism 30 is connected to the connecting portion 22. When locking the cover, the locking mechanism 30 is connected to the upper cover 20 as a whole, and the bottom cover 10 prevents the upper cover 20 from rotating in the opening direction through the locking mechanism 30, thereby realizing the locking of the upper cover 20.

[0036] As Figure 4 and Figure 5As shown in the figure, specifically, the locking mechanism 30 includes a locking piece 31 and a positioning component 32. The connecting portion 22 is provided with a connecting groove 24. The locking piece 31 is located in the connecting groove 24 and is rotatably connected to the connecting groove 24 through a pin shaft. The bottom cover 10 is provided with a locking groove 12. When the upper cover 20 and the bottom cover 10 are in the locked state, the locking piece 31 rotates a certain angle relative to the upper cover 20, so that one end of the upper cover 20 extends into the locking groove 12, and the top surface of the locking groove 12 prevents the locking piece 31 from continuing to rotate. At this time, the positioning component 32 positions the locking piece 31, so that the locking piece 31 and the upper cover 20 are connected as a whole. At this time, the bottom cover 10 prevents the upper cover 20 from rotating in the opening direction through one end of the locking piece 31 extending into the locking groove 12, thereby locking the upper cover 20, so that the upper cover 20 seals the water inlet 11 on the bottom cover 10. And the upper surface of the locking piece 31 abuts against the top surface of the locking groove 12, so that the top end of the water inlet 11 abuts tightly against the first sealing ring 23, thereby making the connection between the upper cover 20 and the bottom cover 10 tight.

[0037] Specifically, one end of the locking piece 31 is a clamping plate 311. When the upper cover 20 and the bottom cover 10 are in the locked state, the locking piece 31 extends into the locking groove 12 through the clamping plate 311, and the bottom cover 20 stops the clamping plate 311 through the locking groove 12 to prevent the upper cover 20 from rotating in the opening direction.

[0038] A receiving groove 312 is provided at one end of the locking piece 31 away from the clamping plate 311. The positioning component 32 is connected to the locking piece 31 through the receiving groove 312. When the locking piece 31 rotates to a preset position relative to the upper cover 20, the positioning component 32 can connect the locking piece 31 and the upper cover 20 as a whole.

[0039] Specifically, the positioning component 32 includes a positioning member 33, an unlocking member 34, and an elastic member 35. The positioning member 33 is located in the receiving groove 312. A positioning groove 25 is provided on the side wall of the connecting groove 24. One end of the positioning member 33 is connected to the elastic member 35. Under the action of the elastic member 35, the end of the positioning member 33 away from the elastic member 35 passes through the side wall of the receiving groove 312 and extends into the positioning groove 25, and is connected with the positioning groove 25 in a matching manner, connecting the locking piece 31 and the upper cover 20 into a whole, and preventing the locking piece 31 from rotating relative to the upper cover 20. The unlocking member 34 is slidably connected to the locking piece 31. One end of the unlocking member 34 extends into the receiving groove 312 and contacts the positioning member 33. The unlocking member 34 can drive the positioning member 33 to move in the direction of pre-tightening the elastic member 35. At this time, the end of the positioning member 33 away from the elastic member 35 can be separated from the positioning groove 25, and the locking piece 31 can rotate relative to the upper cover 20.

[0040] Continue to refer to Figure 6 , further, a positioning protrusion 331 is provided at the end of the positioning member 33 away from the elastic member 35. The receiving groove 312 is provided with a through hole 313. The positioning protrusion 331 extends out of the receiving groove 312 through the through hole 313 and extends into the positioning groove 25, and is connected with the positioning groove 25 in a matching manner. The through hole 313 only allows the positioning protrusion 331 to pass through.

[0041] A first inclined surface 332 is provided on the positioning member 33, and a second inclined surface 341 that fits with the first inclined surface 332 is provided on the unlocking member 34. When an external force is applied to the unlocking member 34 to make the unlocking member 34 move in the direction of extending into the receiving groove 312, the unlocking member 34 drives the positioning member 33 to move inward through the first inclined surface 332 and the second inclined surface 341, pre-tightening the elastic member 35, so that the positioning protrusion 331 is separated from the positioning groove 25, the locking piece 31 can rotate relative to the upper cover 20, and the upper cover 20 can rotate relative to the bottom cover 10 in the opening direction to open the water port 11 on the bottom cover 10. When the locking piece 31 moves to a preset position relative to the upper cover 20, the external force is no longer applied to the unlocking member 34. At this time, the elastic member 35 drives the positioning member 33 to move, the positioning protrusion 331 passes through the through hole 313 and extends into the positioning groove 25, connecting the locking piece 31 and the upper cover 20 into a whole, and at the same time, the positioning member 33 drives the unlocking member 34 to reset through the first inclined surface 332 and the second inclined surface 341.

[0042] In one embodiment, the number of the positioning members 33 is one. One end of the elastic member 35 abuts against the side wall of the receiving groove 312, and the other end abuts against the positioning member 33. The elastic member 35 applies an elastic force to the positioning member 33, so that the positioning protrusion 331 passes through the through hole 313 and cooperates with the positioning groove 312. At the same time, the unlocking member 34 is driven to reset through the first inclined surface 332 and the second inclined surface 341. When unlocking is required, an external force is applied to the unlocking member 34, so that the unlocking member 34 moves into the receiving groove 312. At this time, the unlocking member 34 drives the positioning member 33 to translate in the reverse direction through the second inclined surface 341 and the first inclined surface 332, so that the positioning protrusion 331 disengages from the positioning groove 25. At this time, the lock piece 31 can rotate relative to the upper cover 20.

[0043] In another embodiment, the number of the positioning members 33 is two. The two positioning members 33 are symmetrically distributed in the receiving groove 312, and the elastic member 35 is located between the two positioning members 33 and connects the two positioning members 33 at the same time. The unlocking member 34 is provided with two second inclined surfaces 341, and the two second inclined surfaces 341 are respectively attached to the first inclined surfaces 332 on the two positioning members 33. The through holes 313 are respectively arranged on the opposite side walls of the receiving groove 312, corresponding to the positioning protrusions 331 on the two positioning members 33 respectively. The positioning grooves 25 are respectively arranged on the opposite side walls of the connecting groove 24, cooperating with the positioning protrusions 331 on the two positioning members 33 respectively. When the lock piece 31 rotates relative to the upper cover 20 to a preset position, the elastic member 35 drives the two positioning members 33 to translate towards both sides. The positioning protrusions 331 on the two positioning members 33 respectively pass through the corresponding through holes 313 and extend into the corresponding positioning grooves 25, connecting the lock piece 31 and the upper cover 20 into a whole. When unlocking is required, an external force is applied to the unlocking member 34. At this time, the unlocking member 34 extends into the receiving groove 312. The unlocking member 34 drives the two positioning members 33 to translate in the reverse direction through the cooperation of the second inclined surfaces 341 and the first inclined surfaces 332 on the two positioning members 33 respectively, so that the two positioning protrusions 331 respectively disengage from the corresponding positioning grooves 25. At this time, the lock piece 31 can rotate relative to the upper cover 20.

[0044] Further, the unlocking member 34 is provided with a guiding shaft 342, and the lock piece 31 is provided with a guiding groove 314 cooperating with the guiding shaft 342. The unlocking member 34 slides along the guiding groove 314 through the guiding shaft 342, and the guiding groove 314 prevents the end of the unlocking member 34 extending into the receiving groove 312 from disengaging from the receiving groove 312 through the guiding shaft 342.

[0045] In the present application, the elastic member 35 is a return spring. The return spring can drive the positioning member 33 to move, so that the positioning protrusion 331 passes through the through hole 313 and cooperates with the positioning groove 25; the unlocking member 34 drives the positioning member 33 to translate in the opposite direction, so that the positioning protrusion 331 disengages from the positioning groove 25, and at this time, the positioning member 33 compresses and pre-tightens the return spring.

[0046] Further, clamping protrusions 315 are respectively arranged on both sides of the lock piece 31, and the clamping protrusions 315 abut against the side walls of the connecting groove 24. The two opposite side edges of the connecting groove 24 clamp the lock piece 31 through the clamping protrusions 315, increasing the damping when the lock piece 31 rotates relative to the upper cover 20, and preventing the lock piece 31 from rotating relative to the upper cover 20 when no external force is applied to the lock piece 31.

[0047] Further, the locking mechanism 30 is located in the connecting groove 24, and the connecting groove 24 is located between the rotating shaft and the sealing groove 21, so that the locking mechanism 30 is not located at the outer side wall of the cup lid, which can avoid unlocking the upper cover 20 due to accidental touch and increase the safety.

[0048] The present application also discloses a water cup, which includes a cup body and the above-mentioned cup lid 100, and the cup lid 100 seals the opening at the top of the cup body.

[0049] As Figure 3 shown, specifically, the bottom cover 10 is connected to the cup body, and the water port 11 on the bottom cover 10 is communicated with the inside of the cup body. A fixing groove 13 is provided on the bottom cover 10, and the water port 11 is communicated with the fixing groove 13. The top end of the cup body extends into the fixing groove 13 and is threadedly connected to the fixing groove 13, and the top end of the cup body abuts against the second sealing ring 14 in the fixing groove 13 to realize the sealed connection between the cup body and the bottom cover 10.

[0050] The second sealing ring 14 is made of silica gel material.

[0051] Without departing from the broad spirit and scope of the present invention, the present invention can be set into various embodiments and deformations. The above embodiments are used to illustrate the invention, but do not limit the scope of the present invention.
