Technical Field

[0001] This utility model belongs to the field of water cup technology, and in particular relates to a rotating quick-opening cup lid. Background Technology

[0002] Existing cup lids mostly use a threaded structure, which results in cumbersome opening and closing operations. This is especially problematic for cup lids that require frequent and quick opening (such as sports water bottles), leading to a poor user experience. Therefore, it is necessary to provide a rotary quick-opening cup lid that achieves reliable locking and unlocking through a simple rotation, thereby improving efficiency. Summary of the Invention

The outer lid coaxially covers the outside of the inner lid, and the outer and inner lids are rotatably connected. The side wall of the inner lid has a through hole. The lid also includes a locking mechanism movably disposed within the through hole. Rotating the outer lid can drive the locking mechanism to pass through or retract from the through hole. When the locking mechanism passes through the through hole, it is in a locked state. When the locking mechanism retracts into the through hole, it is in an unlocked state.

[0006] Preferably, the through holes are configured as at least two circumferentially evenly distributed on the side wall of the inner cover; the locking mechanism is a sphere correspondingly disposed in the through hole; the through hole consists of a movable section and a limiting section from the outside to the inside; the inner diameters of the movable section and the limiting section are d2 and d1 respectively, the distance between the spheres is D, and d2 > D > d1; when the outer cover is rotated, the sphere is in the unlocked state when it retracts into the through hole; when the sphere partially protrudes from the through hole, it is in the locked state.

[0007] Preferably, the inner cover has a wall thickness of T, and D > T; the inner sidewall of the outer cover has a driving groove and a clearance groove corresponding to the sphere; the depths of the driving groove and the clearance groove are L1 and L2, respectively, and L2+T≥D>L1+T; when the outer cover is rotated, the sphere can retract into the through hole when the clearance groove corresponds to the sphere, and is in the unlocked state; when the driving groove corresponds to the sphere, the sphere is squeezed by the driving groove so that it partially protrudes from the through hole, and is in the locked state.

[0008] Preferably, the driving groove and the avoidance groove are connected by a slide groove, which is a driving ramp with gradually increasing depth from the driving groove to the avoidance groove.

[0009] Preferably, the inner cover has a wall thickness of T, where T > D; the inner sidewall of the outer cover has at least a driving protrusion and a fixing protrusion corresponding to the sphere; the heights of the driving protrusion and the fixing protrusion are H1 and H2, respectively, where H1+D > T ≥ H2+D; when the outer cover is rotated, the sphere can retract into the through hole when the fixing protrusion corresponds to the sphere, and is in an unlocked state; when the driving protrusion corresponds to the sphere, the sphere is squeezed by the driving protrusion so that it partially protrudes out of the through hole, and is in a locked state.

[0010] Preferably, the driving protrusion and the fixed protrusion are connected by a convex strip; the through holes of the inner cover are all connected by annular grooves; the convex strip moves within the annular grooves; the convex strip is a driving ramp whose height gradually increases from the fixed protrusion to the driving protrusion.

[0011] Preferably, the outer wall of the inner lid has at least one limiting groove; the inner wall of the outer lid has a corresponding limiting block, and the limiting groove and the limiting block cooperate to limit the rotation stroke of the outer lid; when the limiting block abuts against the two ends of the limiting groove respectively, the cup lid is in a locked state or an unlocked state.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1.

Stable structure: The through hole is equipped with a limiting section and a moving section, and the diameter of the sphere is between the inner diameters of the two sections, ensuring smooth movement and reliable limiting of the locking mechanism; 3. High durability: The drive groove / protrusion and the avoidance groove / fixing protrusion on the inner side of the outer cover are smoothly transitioned by the ramp to reduce wear; the limiting groove and the limiting block cooperate to limit the rotation stroke and avoid excessive rotation; 4. Wide applicability: Multiple sets of through holes and circumferentially distributed spheres enhance the stability of the lid and are suitable for all types of water cups; 5. Low cost: The main components are only the outer cover, inner cover and ball, and the quick-opening function can be achieved with fewer parts. Attached Figure Description

[0019] To make the technical solution of this utility model clearer, the following description is in conjunction with the appendix. Figures 1 to 6 This specification provides a detailed description of the present invention. It should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the scope of protection of the present invention.

[0020] A rotary quick-opening cup lid includes at least an outer lid 1 and an inner lid 2; both the outer lid 1 and the inner lid 2 are cap-like structures with openings at the bottom, the outer lid 1 coaxially covers the outside of the inner lid 2, and the outer lid 1 and the inner lid 2 are rotatably connected; it also includes a locking mechanism movably disposed in a through hole 21 on the side wall of the inner lid 2, rotating the outer lid 1 can drive the locking mechanism to partially pass through or retract from the through hole 21; when the locking mechanism passes through the through hole 21, the locking mechanism can cooperate with the locking groove of the cup mouth to lock the cup lid; when the locking mechanism retracts into the through hole 21, the cup lid can be removed from the cup mouth.

[0021] In one embodiment, the through holes 21 are configured as at least two circumferentially evenly distributed on the sidewall of the inner cover 2; the locking mechanism is a sphere 3 (the sphere 3 can be made of stainless steel, copper, titanium, or other metal materials) correspondingly disposed within the through holes 21; such as Figure 5 As shown, the through hole 21 consists of a movable section 211 and a limiting section 212 from the outside to the inside. The diameter d2 of the movable section 211 is greater than the diameter d1 of the limiting section 212. The diameter of the sphere 3 is D, and d2 > D > d1. This allows the sphere 3 to partially pass through the through hole 21, but it is restricted between the outer cover 1 and the limiting section 212.

[0022] In one embodiment, the inner cover 2 has a wall thickness of T, and D > T; the inner sidewall of the outer cover 1 is provided with a driving groove 11 and a clearance groove 12 corresponding to the sphere 3; the depths of the driving groove 11 and the clearance groove 12 are L1 and L2, respectively, and L2 + T ≥ D > L1 + T; when the outer cover 1 is rotated so that the clearance groove 12 corresponds to the sphere 3, the sphere 3 can retract into the through hole 21 (part of the sphere 3 is hidden in the clearance groove 12), and is in an unlocked state; when the driving groove 11 corresponds to the sphere 3, the sphere 3 is squeezed by the driving groove 11 so that part of it passes through the through hole 21 (the part of the sphere 3 that passes through the through hole 21 can cooperate with the locking groove of the cup mouth to lock), and is in a locked state.

[0023] Specifically, the drive groove 11 and the avoidance groove 12 are connected by a slide groove. The slide groove is a drive ramp whose depth gradually increases from the drive groove 11 to the avoidance groove 12. During the rotation of the outer cover 1, the drive ramp gradually squeezes the sphere 3 to move radially inward.

[0024] In one embodiment, T > D; the inner sidewall of the outer cover 1 is provided with a driving protrusion and a fixing protrusion corresponding to the sphere 3; the heights of the driving protrusion and the fixing protrusion are H1 and H2 respectively, and H1+D>T≥H2+D; when the outer cover 1 is rotated so that the fixing protrusion corresponds to the sphere 3, the sphere 3 can retract into the through hole 21 and be in the unlocked state; when the driving protrusion corresponds to the sphere 3, the sphere 3 is squeezed by the driving protrusion so that it partially protrudes out of the through hole 21 (the part of the sphere 3 that protrudes out of the through hole 21 can cooperate with the locking groove of the cup mouth to lock), and is in the locked state.

[0025] Specifically, the driving protrusion and the fixed protrusion are connected by a convex strip, and the through holes 21 of the inner cover 2 are all connected by annular grooves. The convex strip moves within the annular grooves. The convex strip is a driving ramp whose height gradually increases from the fixed protrusion to the driving protrusion. During the rotation of the outer cover 1, the driving ramp gradually squeezes the sphere 3 to move radially inward.

[0026] In one embodiment, the outer wall of the inner cover 2 is provided with at least one limiting groove 22, and the inner wall of the outer cover 1 is provided with a corresponding limiting block 13. The limiting groove 22 and the limiting block 15 cooperate to limit the rotation stroke of the outer cover 1. When the limiting block 13 abuts against the two ends of the limiting groove 22 respectively, the cup lid is in a locked state or an unlocked state.

[0027] Specifically, a sealing ring 4 is provided below the inner lid 2 to seal the water by contacting the mouth of the cup.

[0028] Specifically, the rotation structure of the outer cover 1 and the inner cover 2 can be achieved through bearings, or as shown in the attached diagram. Figure 2 Alternatively, the screw shown in Figure 3 can be used, or a snap-on rotating shaft can be used (i.e., a rotating shaft is set on the outer cover 1 or the inner cover 2, the end of the rotating shaft is an elastic snap, and the inner cover 2 or the outer cover 1 is provided with a corresponding rotating hole. After the rotating shaft is inserted into the rotating hole, it is snapped and limited to prevent it from falling off). This rotating structure has been widely used in many fields, and will not be described in detail here.

[0029] Specifically, four through holes 21 and four spheres 3 are set to make the lid fit more securely and stably on the mouth of the cup.

[0030] The above description is merely a specific example of this utility model and does not constitute any limitation on this utility model. Obviously, those skilled in the art, after understanding the content and principle of this utility model, may make various modifications and changes in form and details without departing from the principle and structure of this utility model. However, these modifications and changes based on the concept of this utility model are still within the protection scope of the claims of this utility model.
