DETAILED DESCRIPTION
[0030] Specific embodiments of the present application are described in conjunction with the accompanying drawings and the following description to teach those skilled in the art how to make and use the best mode of the present application. In order to teach the principles of the application, some conventional aspects have been simplified or omitted. Those skilled in the art should understand that variations from these embodiments fall within the scope of the present application. Those skilled in the art should understand that the following features can be combined in various ways to form multiple variations of the present application. Terms such as "upper", "lower", "left", "right", "middle" and "one" cited in this application are only for the convenience of description and are not intended to limit the scope of the implementation of the present invention. Changes or adjustments to their relative relationships should also be regarded as the scope of the implementation of the present invention without substantial changes in the technical content. Therefore, the present application is not limited to the specific embodiments described below, but is only limited by the claims and their equivalents.
[0031] Example 1
[0032] like Figures 1 to 8 As shown, this embodiment relates to a snap-on self-locking cup cover, which includes a lower cover 1, an upper cover 2, a flip cover 3 and a self-locking device. The upper cover 2 is connected to the lower cover 1, the flip cover 3 is hinged to the upper cover 2, and the self-locking device is installed in the upper cover 2. The self-locking device includes a locking member 4 and a connecting sleeve 5. The locking member 4 is connected to the connecting sleeve 5 to control the downward pressing of the connecting sleeve 5. The connecting sleeve 5 is snapped with the lower end of the flip cover 3. When the connecting sleeve 5 is pressed down, the connecting sleeve 5 is disconnected from the lower end of the flip cover 3, and the flip cover 3 opens.
[0033] Specifically, in the embodiment of the present application, the connecting sleeve 5 includes a pressing portion 51 connected to the lock member 4, a snap portion 52 snapped to the flip cover 3, and a horizontal connecting frame 53 for connecting the pressing portion 51 and the snap portion 52. The pressing portion 51 is located in the pressing groove 21 of the upper cover 2, and the horizontal connecting frame 53 and the snap portion 52 are arranged in the upper cover 2. By pressing the pressing portion 51, the connecting sleeve 5 moves, and finally the snap portion 52 on the connecting sleeve 5 is disconnected from the flip cover 3.
[0034] A slide groove 511 and a through groove 512 are provided on the pressing portion 51, and a slider 41 and a card foot 42 are provided on the lock member 4. The lock member 4 is connected to the slide groove 511 by sliding up and down through the slider 41, and the card foot 42 passes through the through groove 512 and enters the upper cover 2. The end of the card foot 42 adopts a triangular structure of elastic material, which clamps the slide groove 511 by the triangular structure to prevent the lock member 4 from separating from the pressing portion 51. There is also a sensing protrusion 43 on the lock member 4, and a protrusion 513 for switching the lock is correspondingly provided on the pressing portion 51. When the sensing protrusion 43 slides over the protrusion 513, it indicates that the lock member 4 enters the self-locking position from the unlocking position or enters the unlocking position from the self-locking position.
[0035] In addition, the top surface of the lower cover 1 is provided with a limit 11 for limiting the card foot 42. When the lock member 4 slides down, that is, when the lock member 4 is in the self-locking position, the end of the card foot 42 is against the limit 11. Due to the limitation of the limit 11, the lock member 4 and the pressing portion 51 cannot be pressed down. When the lock member 4 slides upward, that is, when the lock member 4 is in the unlocking position, the end of the card foot 42 is higher than the upper limit position of the limit 11. The limit 11 cannot form a limiting effect on the card foot 42, and the lock member 4 and the pressing portion 51 can be pressed down.
[0036] A first buckle 521 is provided on the top of the buckle portion 52 , and a second buckle 31 is provided on the flip cover 3 . The second buckle 31 passes through the top surface of the upper cover 2 and is engaged with the first buckle 521 .
[0037] In the embodiment of the present application, the top surface of the lower cover 1 is provided with four limiting supports 12, and the horizontal connecting frame 53 is positioned on the limiting supports 12. The top of the horizontal connecting frame 53 is provided with a first limiting step 531, and the bottom surface of the upper cover 2 is provided with a second limiting step 22 that cooperates with the first limiting step 531. The limiting supports 12, the first limiting step 531, and the second limiting step 22 limit the horizontal connecting frame 53 in the vertical, horizontal, and left and right directions, preventing the horizontal connecting frame 53 from shifting during use and providing a more stable structure.
[0038] Furthermore, for ease of use, a return spring 54 is mounted on the inner side of the pressing portion 51. The other end of the return spring 54 abuts against a stop plate 23 connected to the bottom of the top cover 2. The lower end of the stop plate 23 is restrained by two stoppers 13 on the top surface of the lower cover 1. When pressed, the return spring 54 is compressed. After the pressing is completed, the lock member 4 and the connecting buckle 5 return to their original position under the force of the return spring 54.
[0039] In an embodiment of the present application, the flip cover 3 is connected to the top of the upper cover 2 through a hinge shaft 6. A groove for accommodating the flip cover 3 is also provided on the top of the upper cover 2. A torsion spring 7 is installed on the hinge shaft 6. After unlocking, the flip cover 3 can be quickly popped open under the action of the torsion spring 7. In addition, a silicone member 8 for sealing the water outlet and the exhaust port is provided at the bottom of the flip cover 3.
[0040] In an embodiment of the present application, the top surface of the lower cover 1 is provided with an installation limit groove 14, and the inner side of the upper cover 2 is provided with an installation limit rib 24 that cooperates with the installation limit groove 14. The upper cover 2 and the lower cover 1 are connected by the installation limit rib 24 and the installation limit groove 14.
[0041] Example 2
[0042] like Figure 9 As shown, this embodiment discloses a water cup, which includes the snap-on self-locking cup cover and the cup body 9 in Example 1. The cup body 9 is connected to the lower cover 1 through threads.
[0043] Since those skilled in the art can easily think of it, any modifications, equivalent substitutions, improvements, etc. made within the concept and principle of the application should be included in the scope of the claims of this application.
