Description

Technical Field

[0001] This utility model specifically relates to a plastic flip-top button structure. Background Technology

[0002] As a widely used type of cup lid in daily life, the structural design of pop-up cup lids directly affects their ease of use and reliability. Currently, most pop-up cup lids on the market adopt a front-opening structure, where the opening button is located at the lid opening point. The overall structure typically consists of a base and a flip lid: one end of the base and one end of the flip lid are rotatably connected by a spring and a pivot, while the other end of the base and the other end of the flip lid are fixed together by a button's locking mechanism and a locking key. When it is necessary to open the lid, pressing or pushing the button unlocks the locking mechanism, and the flip lid automatically pops open under the spring's elasticity, completing the opening action.

[0003] However, this traditional front pop-out lid structure has obvious limitations. The lid opening button does not have a self-locking function. Since the lid opening button is directly connected to the lid opening point, it is easy to accidentally open the lid due to accidental button press during carrying, causing liquid leakage. Utility Model Content

[0004] In view of the defects of the existing technology, the technical problem to be solved by this utility model is to propose a plastic flip-top button structure.

[0005] A plastic flip-top button structure includes a button body, one end of which has a protruding limiting portion, and the other end of which has a connecting portion at its center. A connecting cover is movably fitted onto the connecting portion. A limiting block is rotatably provided around the connecting cover. The distance between the center of the connecting cover and the outer side of the limiting block is less than or equal to the radius of the button body. A transmission component is provided between the connecting portion and the connecting cover, which can drive the limiting block to rotate and protrude outward from the periphery of the button body as the connecting cover moves. A recess is provided on the periphery of the connecting cover corresponding to the limiting block. The upper end of the limiting block can rotatably abut against the recess to limit the rotation angle of the limiting block.

[0006] In one embodiment, the transmission component includes an external thread disposed on the periphery of the connecting portion, the connecting cover is threadedly connected to the external thread, the button body is provided with a conical surface at one end coplanar with the connecting portion, and the limiting block can abut against the conical surface as the connecting cover moves along the external thread.

[0007] In one embodiment, the button body has a protrusion at one end that is coplanar with the limiting portion, which can be positioned and engaged with the spring.

[0008] In one embodiment, a torsion spring is provided at the rotatable connection between the limiting block and the connecting cover, so that the limiting block is kept in a retracted state that is tightly attached to the side wall of the connecting cover.

[0009] In one embodiment, the outer periphery of the connecting cover is provided with anti-slip texture.

[0010] In one embodiment, two or more limiting portions are evenly distributed along the circumference of the button body.

[0011] In one embodiment, the connecting part and the button body are integrally injection molded.

[0012] In summary, the advantages of this utility model over the prior art are:

[0013] This invention adds a connecting cover and a rotatable, outward-folding limiting block to one end of the button body. In the initial state, the button body is housed in the mounting hole of the outer bottom cover or flip cover. The limiting part of the button body cooperates with the guide groove of the bottom cover or flip cover, allowing the button body to make a linear pressing displacement relative to the outer mounting hole. The connecting cover and the limiting block can be housed within the area of ​​the outer contour of the button body, without causing interference when the button body is pressed. When the button body needs to be locked, the user screws on the connecting cover. The limiting block moves with the connecting cover and is driven to bulge outward through the transmission component. As a result, the limiting block bulges outward beyond the area of ​​the outer mounting hole, thus preventing the button from being pressed to drive the opening action (i.e., the limiting block cannot pass through the outer mounting hole with the displacement of the button body), achieving self-locking of the button.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0019] like Figures 1 to 4The present invention preferably provides a plastic flip button structure, including a button body 1. One end of the button body 1 has a limiting part 2 protruding outward, and the other end of the button body 1 has a connecting part 3 at its center. A connecting cover 4 is movably sleeved on the connecting part 3. A limiting block 5 is provided around the connecting cover 4 and rotates circumferentially. The distance between the center of the connecting cover 4 and the outer side of the limiting block 5 is less than or equal to the radius of the button body 1. A transmission member 6 is provided between the connecting part 3 and the connecting cover 4, which can drive the limiting block 5 to rotate and protrude outward from the circumference of the button body 1 with the movement of the connecting cover 4. A recess 9 is recessed on the circumference of the connecting cover 4 corresponding to the limiting block 5. The upper end of the limiting block 5 can rotate and abut against the recess 9 to limit the rotation angle of the limiting block 5.

[0020] Specifically, a connecting cover and a rotatable, outward-folding limiting block are added to one end of the button body, such as... Figure 4 As shown, in its initial state, the button body is housed within the mounting hole of the external bottom cover or flip cover. The limiting part of the button body engages with the guide groove of the bottom cover or flip cover, allowing the button body to perform a linear pressing displacement relative to the external mounting hole. The connecting cover and the limiting block are housed within the area of ​​the button body's outer contour, preventing interference with the button body's pressing action. Figure 3 As shown, when the button body needs to be locked, the user can select and tighten the connecting cover. The limiting block moves with the displacement of the connecting cover and is driven to bulge outward through the transmission component. As a result, the limiting block bulges outward beyond the area of ​​the external mounting hole, thus preventing the button from being pressed to drive the opening action (i.e., the limiting block cannot pass through the external mounting hole with the displacement of the button body), thereby achieving the self-locking of the button.

[0021] Furthermore, the transmission component 6 includes an external thread disposed on the periphery of the connecting portion 3, the connecting cover 4 is threadedly connected to the external thread, and the button body 1 has a conical surface 7 at one end coplanar with the connecting portion 3. The limiting block 5 can abut against the conical surface 7 as the connecting cover 4 moves along the external thread. Specifically, the external thread of the connecting portion engages with the internal thread of the connecting cover. When the connecting cover is screwed on, the connecting cover moves axially along the connecting portion. The conical surface at the end of the button body contacts the limiting block as the connecting cover moves, pushing the limiting block to rotate outward around the rotational axis, thus protruding beyond the range of the mounting hole.

[0022] Furthermore, the button body 1 has a protrusion 8 at one end coplanar with the limiting part 2, which can engage with the spring for positioning. Specifically, the protrusion on the button body can engage with the external spring for positioning and installation. After the button body is pressed, the spring force applies a restoring force through the protrusion, returning it to its initial position and ensuring the accuracy of the next press. The protrusion is cylindrical and integrally injection molded with one end of the button body's limiting part, with a diameter slightly smaller than the inner diameter of the spring. The height is set according to the spring compression to ensure stable spring mounting and not affect button pressing and reset.

[0023] Furthermore, a torsion spring (not shown in the figure) is provided at the rotatable connection between the limiting block 5 and the connecting cover 4. The torsion spring keeps the limiting block 5 in a retracted state, tightly pressed against the side wall of the connecting cover 4. The torsion spring at the rotatable connection between the limiting block and the connecting cover always keeps the limiting block in a retracted state, tightly pressed against the side wall of the connecting cover. When the thrust of the transmission component is greater than the spring force of the torsion spring, the limiting block rotates outward; when the thrust disappears, the torsion spring resets it, facilitating unlocking and retraction.

[0024] Furthermore, the outer periphery of the connecting cover 4 is provided with anti-slip texture. The anti-slip texture on the outer periphery of the connecting cover increases the friction of the hand, making it easier for the user to twist and turn, and preventing slippage.

[0025] Furthermore, two or more limiting parts 2 are evenly distributed along the circumference of the button body 1. The two or more limiting parts are evenly distributed along the circumference of the button body and cooperate with the external guide groove at multiple points to ensure the stability of the button body when linearly pressed, prevent deviation, and make the pressing more precise.

[0026] Furthermore, the connecting part 3 and the button body 1 are integrally injection molded. The integral injection molding of the connecting part and the button body eliminates connection gaps, improving structural strength and stability, preventing wobbling during pressing due to assembly gaps, and ensuring precise movement of the transmission components and limit blocks.
