Description

Technical Field

[0001] This utility model relates to a water cup lid, and more particularly to a water cup lid opening and closing locking structure. Background Technology

[0002] Water cups are containers we use to drink water in our daily lives. Common types include direct-drinking cups and straw cups. Chinese utility model patent CN217771981U discloses a drinking cup that is easy to clean. This cup offers both direct-drinking and straw-drinking options. The patented cap is threadedly connected to a flip-top and covers the spout. This threaded opening and closing mechanism is inconvenient to use.

[0003] Currently, the most common method for opening and closing the lid is through a button latch. In this type of structure, the button is typically a metal pin mounted on the lid. Pressing the button causes it to rotate around the metal pin, thus unlocking or locking the lid.

Detailed Implementation

[0021] The present invention will now be described in further detail with reference to the accompanying drawings.

[0022] like Figures 1 to 8 As shown, this utility model provides a water cup lid opening and closing locking structure, including a bottom cover 1, a connecting cover 2, and a flip cover 3. The inner surface of the outer side wall of the bottom cover 1 is provided with an internal thread 11 for connecting with the cup body. The top front side of the bottom cover 1 is provided with a mounting groove 12. The bottom of the mounting groove 12 is provided with a guide strip 121 along the front-back direction. A slide 4 that can slide back and forth along the guide strip 121 is installed in the mounting groove 12. A compression spring is provided between the rear side of the slide 4 and the rear side wall of the mounting groove 12. A locking hole 41 is opened on the top surface of the slide 4. A hook 42 is provided in the locking hole 41. A vertical locking strip 43 is provided on the front side wall of the slide 4. A sliding button 5 is provided on the front side of the slide 4. The inner side of the sliding button 5 is provided with two vertical positioning grooves 51 on the left and right sides that engage with the vertical locking strip 43 for positioning. A clearance groove 52 is provided on the lower rear side of the sliding button 5. When the sliding button 5 slides left and right, it engages with the vertical locking strip 43 through one of the vertical positioning grooves 51. When one of the vertical positioning grooves 51 is engaged, the clearance groove 52 is located outside the guide strip 121, allowing the sliding button 5 to be pressed backward into the mounting groove 12. The connecting cover 2 is inserted into the upper part of the bottom cover 1 from top to bottom and limits the sliding button 5 and the sliding base 4 inside. The top surface of the connecting cover 2 has an insertion hole 21 at the position of the locking hole 41. The front side of the connecting cover 2 has a strip hole 22 for the sliding button 5 to extend and push left and right. The flip cover 3 is hinged to the rear side of the connecting cover 2. A perforated locking plate 31 is provided on the front side of the bottom of the flip cover 3. When the flip cover 3 is closed downward, the perforated locking plate 31 passes through the insertion hole 21 and is inserted into the locking hole 41 and locked by the hook 42.

[0023] In the above scheme, the rear center area of ​​the connecting cover 2 and the bottom cover 1 is provided with a through mounting hole, and a silicone suction nozzle 6 is installed in the mounting hole. The front center area of ​​the top of the connecting cover 2 is provided with a horizontal retaining strip 23, and the front center area of ​​the bottom of the flip cover 3 is provided with a horizontal retaining plate 32. When the flip cover 3 is closed on the connecting cover 2, the silicone suction nozzle 6 is squeezed and laid down between the horizontal retaining plate 32 and the horizontal retaining strip 23 and fixed.

[0024] Specifically, the top surface of the bottom cover 1 extends upward to form a protrusion 13, and a through vent 131 is provided inside the protrusion 13. The connecting cover 2 is provided with a through mounting hole on its top surface corresponding to the position of the protrusion 13. Specifically, the vent 131 can be located in the middle of the horizontal retaining strip 23. When the flip cover 3 is closed, the silicone suction nozzle 6 can squeeze and cover the vent 131. When the flip cover 3 is opened, the silicone suction nozzle 6 returns to its upright position, and the vent 131 opens to balance the internal and external air pressure.

[0025] Specifically, the rear side of the connecting cover 2 is provided with two first hinge seats 24 on the left and right, and the rear side of the flip cover 3 is provided with two second hinge seats 33 on the left and right. The second hinge seats 33 are located inside the first hinge seats 24, and a handle 7 is provided between the two second hinge seats 33. A pin is inserted through the first hinge seats 24, the second hinge seats 33, and the handle 7 to maintain a rotatable connection, and a torsion spring is provided on the pin.

[0026] In addition, a sealing ring is provided on the top inner side of the bottom cover 1. After the bottom cover 1 and the cup body are threaded together, the top surface of the cup body is squeezed to press the sealing ring to achieve a seal at that location.

[0027] Furthermore, the outer side of the bottom cover 1 is provided with a vertical positioning groove 14 and a horizontal locking strip 15, and the inner side of the connecting cover 2 is provided with a vertical positioning rib and a horizontal positioning groove. When the connecting cover 2 is inserted into the bottom cover 1 from top to bottom, it is guided by the vertical positioning groove 14 and the positioning rib. After the connecting cover 2 is inserted into place, it is positioned by the horizontal locking strip 15 and the positioning groove.

[0028] In this invention, the slider 5 can move left and right; when it is moved to the left, it is in the unlocked state, such as... Figure 5 and Figure 6 As shown, the clearance groove 52 is located outside the guide strip 121, allowing the slide button 5 to be pressed backward into the mounting groove 12. The slide button 5 can be pushed backward, causing the slide block 4 to move backward against the force of the compression spring. The hole on the perforated plate 31 of the flip cover 3 disengages from the hook 42, and the flip cover 3 springs open upward under the action of the torsion spring. Simultaneously, the vent 131 maintains a balance with the internal and external air pressure. When the slide button 5 is moved to the right, it is in a locked state, as shown... Figure 7 and Figure 8As shown, at this time, the clearance groove 52 on the slider 5 is misaligned with the guide bar 121, and the rear side of the slider 5 directly contacts the guide bar 121. The slider 5 cannot be moved backward, and the perforated plate 31 on the flip cover 3 is stuck by the hook 42, so the flip cover 3 cannot be flipped up and opened.

[0029] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the utility model. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
