[0001] This utility model relates to a self-locking cup lid and a cup, belonging to the field of cup technology. Background Technology

[0002] The self-locking thermos lid is an innovative design aimed at improving the safety, sealing, and convenience of thermoses. Traditional thermos lids typically have a button and a latch; the latch locks the lid in place, and pressing the button releases the latch and lid. The self-locking lid, however, incorporates a locking mechanism that locks the button in place, preventing accidental presses and leakage. Traditional self-locking mechanisms usually require a separate locking device (such as a slider, knob, or external locking mechanism), increasing the number of parts and assembly complexity. Separating the locking mechanism from the button requires individual operation of both, making it cumbersome and inconvenient for one-handed use. Utility Model Content

By directly pushing and pulling the locking component on the button, integrated operation is achieved, allowing users to easily and intuitively control the locking and unlocking states, thus improving the user experience.

[0017] 2. Integrating the locking component into the button saves space, making the cup lid design more compact and aesthetically pleasing, and contributing to weight reduction and miniaturization.

[0018] 3. The locking component is directly integrated with the button, and the locking force and button force are concentrated, which reduces the instability problems that may be caused by the relative movement between independent components and improves the reliability of locking.

[0019] 4. The button and locking components are integrated into a single design, allowing for easy switching of the locking state with a simple push up or down motion. This is intuitive and clear, significantly reducing the risk of accidental operation.

[0020] 5. This design is more suitable for one-handed operation or quick switching, and performs particularly well in scenarios where convenience is required, such as sports and driving. Attached Figure Description

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] like Figure 1 As shown, this utility model provides a cup, including a cup body 1 and a self-locking cup lid 2. The self-locking cup lid 2 integrates a locking member 3 onto a button 4. By pushing the locking member 3 upwards, it moves upwards relative to the button 4, allowing the limiting pin on the locking member 3 to be inserted into the limiting hole on the mounting base, thus preventing the button 4 from being pressed down and locking the button 4. When it is necessary to open the cup lid, the locking member 3 is pushed downwards, causing the limiting pin to disengage from the limiting hole, and the button 4 can then be pressed.

[0029] Specifically, such as Figure 2-6 As shown, the self-locking cup lid 2 includes a connecting part 21 for connecting to the cup body 1 and an upper cover part 22 hinged to the connecting part 21. The connecting part 21 is cylindrical and is threaded to the upper part of the cup body 1.
