Detailed Implementation
[0030] To make the technical means, creative features, objectives and effects of this utility model easy to understand, the following describes the cup lid and cup of this utility model in detail with reference to the embodiments and accompanying drawings.
[0031] <Example 1>
[0032] This embodiment proposes a cup lid 10, including a lid body 1, a top cover 2, a switch button 3, and a locking assembly. The lid body 1 has a water outlet 11. The top cover 2 is rotatably connected to the lid body 1 via a torsion spring 92 and has a closed state that always covers the water outlet 11, and an open state that can rotate relative to the lid body 1 to expose the water outlet 11. The switch button 3 is movably disposed on the lid body 1, and pressing the switch button 3 changes the top cover 2 from the closed state to the open state. The locking assembly is installed on the lid body 1 and can cooperate with the switch button 3 to switch the top cover 2 between the closed and open states. When the locking assembly is locked, the switch button 3 cannot be pressed, thus keeping the top cover 2 in the closed state. When the locking assembly is unlocked, pressing the switch button 3 allows the top cover 2 to rotate under the action of the torsion spring 92, thereby changing it to the open state.
[0033] Among them, the end of the top cover 2 near the switch button 3 protrudes towards the side of the switch button 3 (e.g., Figure 2 The inner side of the top cover 2 (as shown) has a first retaining edge 21, and the switch button 3 has a locking part 31, which faces the top cover 2 (e.g., Figure 2 The locking part 31 shown has a second fastening edge 32 on its outer side that mates with the first fastening edge 21, such as... Figure 2 As shown, when the second fastening edge 32 is fastened to the first fastening edge 21, the top cover 2 is in the closed state. The locking assembly has a locking member 4 and a locking trigger member 5. The locking member 4 is movably disposed between the cover body 1 and the locking part 31; the locking trigger member 5 is rotatably disposed on the cover body 1 to drive the locking member 4 to move; when the locking member 4 moves to a point where it overlaps with the projection of the locking part 31 in the moving direction of the switch button 3, that is, the locking member 4 will abut against one side of the locking part 31. At this time, the locking part 31 is blocked, so the switch button 3 cannot be pressed to open the top cover 2, and the top cover 2 can be in the closed state.
[0034] The moving direction of the locking member 4 is perpendicular to the moving direction of the switch button 3. In this embodiment, the moving direction of the locking member 4 is vertical, and the moving direction of the switch button 3 is horizontal. That is, rotating the locking trigger member 5 can drive the locking member 4 to move up and down. When the locking member 4 moves up to a point where it overlaps with the projection of the locking part 31 in the horizontal direction (e.g., ...), the locking member 4 moves up to a point where it overlaps with the projection of the locking part 31 in the horizontal direction. Figure 2 and Figure 3 (As shown in the diagram), the locking element 4 is located in the space between the locking part 31 and the locking trigger 5, forming a locked state. At this time, the switch button 3 cannot move inward, and the top cover 2 cannot be rotated open, always covering the water outlet, thus remaining in the closed state; when the locking element 4 moves down to a point where its projection in the horizontal direction does not overlap with that of the locking part 31, the locking element 4 moves out of the space between the locking part 31 and the locking trigger 5 (as shown in the diagram). Figure 4 As shown), the rear side of the locking part 31 is unobstructed, forming an unlocked state. At this time, the switch button 3 can be pressed and moved inward. When the second latch 32 leaves the first latch 21, the top cover 2 can be rotated upward and opened under the action of the torsion spring 92, thus forming an open state.
[0035] like Figures 5-7 As shown, the locking member 4 is arc-shaped and positioned outside the water outlet 11, with a guide groove 41. The locking trigger member 5 has a guide pin 51 that can extend into the guide groove 41. The guide groove 41 has a locking end 411 and an unlocking end 412, and the locking end 411 and the unlocking end 412 have a height difference in the moving direction of the locking member 4. In this embodiment, as... Figure 5As shown, the locking member 4 is provided with a pair of guide grooves 41, which can make the locking member 4 bear force more evenly and facilitate its up and down movement; the guide groove 41 is an inclined arc groove, and the height of the unlocking end 412 in the vertical direction is higher than that of the unlocking end 412 in the vertical direction. When the guide pin 51 rotates to the locking end 411, the locking member 4 moves to the area where the projection of the locking part 31 in the moving direction of the switch button 3 overlaps with the area where the projection of the locking part 31 in the moving direction of the switch button 3 overlaps with the area where the projection of the locking part 31 in the moving direction of the switch button 3 does not overlap with the area where the locking part 31 in the moving direction of the switch button 3 overlaps with the area where the locking part 4 ...
[0036] like Figure 2 As shown, the water outlet 11 includes a water outlet 111 and a water outlet step 112. The cover 1 has a lower cover 14 and an upper cover 15. The lower cover 14 has a water outlet 111, and a mounting opening 141 for mounting a switch button 3 is provided near the water outlet 111. The upper cover 15 can be installed above the lower cover 14 via a snap-fit structure and has a water outlet step 112 corresponding to the water outlet 111. Figure 8 As shown, the lower cover 14 of the cover body 1 has an arc-shaped locking groove 12 on the outer periphery of the water outlet 111 of the water outlet 11 for accommodating the locking member 4. The locking groove 12 is connected to the mounting port 141, which is located in the middle of the locking groove 12. Figures 5-10 As shown, the locking trigger 5 has a mating part 52 and a lever part 53. The mating part 52 is annular, and the water outlet step 112 is also annular. The mating part 52 is fitted around the outer periphery of the water outlet step 112. The mating part 52 has a locking block 521 that can extend into the locking groove 12. The locking block 521 is provided with a guide pin 51. The inner end of the lever part 53 is connected to the mating part 52, and the outer end extends outward and protrudes from the cover 1 and / or the top cover 2. By moving the lever part 53, the mating part 52 is rotated, and the guide pin 51 rotates in the guide groove 41, causing the locking member 4 to move. The mating part 52 also has a limiting groove 522 on the side facing the water outlet step 112. A limiting strip 113 on the outer periphery of the water outlet step 112 mates with the limiting groove 522. The limiting groove 522 and the limiting strip 113 cooperate with each other to restrict the rotation of the locking trigger 5.
[0037] like Figure 1 As shown, in this embodiment, the lever portion 53 is located on the opposite side of the switch button 3. The upper cover 15 of the cover body 1 has a recessed area in the middle to form a region for mounting the top cover 2. The lever portion 53 extends outward and protrudes from the top cover 2, and is placed in the recessed area in the middle, so that the user can apply force to the lever portion 53 to cause the locking trigger 5 to rotate. Mounting positions for mounting torsion springs 92 are also formed on both sides of the recessed area in the middle of the upper cover 15.
[0038] like Figure 8 As shown, a limiting block 13 is formed on the side of the cover 1 facing the switch button 3, as... Figure 5 As shown, the locking element 4 has a limiting groove 42 that mates with the limiting block 13. Figure 9 As shown, the limiting block 13 is inserted in the limiting groove 42 to limit the two sides of the locking member 4, so as to prevent the locking member 4 from rotating, and so that the locking member 4 can only move up and down under the drive of the locking trigger member 5.
[0039] A drinking spout 6 is installed at the water outlet step 112. A sealing ring 71 is provided between the drinking spout 6 and the water outlet step 112. A soft rubber plug 8 is provided on the inside of the top cover 2 to seal the drinking spout 6. A return spring 91 is provided between the switch button 3 and the mounting port 141. The drinking spout 6 can be a straw spout used with a straw or a dual-purpose spout.
[0040] The cup lid in this embodiment is equipped with a locking component, which includes a locking element and a locking trigger. The locking element moves when the locking trigger rotates. The switch button has a locking part that cooperates with the locking element. When the locking element moves to an overlap with the projection of the locking part in the direction of movement of the switch button, the switch button cannot move due to the obstruction of the locking element, thus preventing the lid from being opened and keeping it in a closed state to prevent the lid from being opened arbitrarily. Furthermore, the locking structure in this embodiment uses the rotation of the locking trigger to move the locking element, which is simple to operate and has a good locking effect. It is less likely to be accidentally activated, thus enhancing security.
