Description

Technical Field

[0001] The utility model relates to a liquid container, in particular to a cover body capable of being unlocked by rotation and a water cup thereof. Background Art

[0002] The cover body mainly used for sports water bottles is generally provided with a convenient flip cover structure. In order to prevent the flip cover from being opened accidentally and to ensure carrying safety, a locking structure is generally provided for the flip cover.

[0003] The flip cover locking structure in the prior art generally adopts the form of pressing to unlock. For example, the Chinese patent announcement with announcement number CN219206174U discloses an automatic locking and unlocking structure for a flip-cover type cup cover, and its technical points are: the structure forms a slide limit and yield area on the surface opposite to the hinge on the flip cover cup body; a latch is positioned on the outer peripheral side of the limit member, and a second hook is formed on the latch to cooperate with the first hook provided at the bottom of the upper cover; a guide through hole is opened on the latch, and a slide that can elastically reciprocate axially in the guide through hole is movably penetrated in the circumferential limit direction of the guide through hole, and the slide protrusion on the slide is accommodated in the slide limit and yield area after passing through the guide through hole and moves in the slide limit and yield area to realize the engagement and unlocking of the first hook and the second hook.

[0004] The above technical solution has a common problem of the spring-loaded lid unlocking structure, that is, the component that is responsible for restricting the flip cover and the component that utilizes the deformation of the elastic member or its own deformation to realize opening and closing are the same component. Then there is a contradiction: if the restricting force on the flip cover is large, the force required for the opening and closing operation will inevitably increase; if the restricting force on the cup lid is small, the risk of accidental opening of the flip cover increases; therefore, it is necessary to propose a new solution to solve this problem.

[0008] The utility model is further configured as follows: the safety lock plate is provided with a lever, the lock ring is provided with a vertical through groove and a horizontal through groove which are clearance-matched with the lever; the horizontal through groove has a locking end and an unlocking end, and the vertical through groove is connected to the locking end of the horizontal through groove.

[0009] The utility model is further configured as follows: the flip cover is assembled to form a cover shell for the safety lock piece to lift and slide.

[0010] The utility model is further configured as follows: the safety lock plate is provided with two elastic arms, the elastic arms are provided with an upper clamping recess and a lower clamping recess, the inner wall of the shell is provided with a clamping protrusion that cooperates with the upper clamping recess and the lower clamping recess; when the clamping protrusion is embedded in the upper clamping recess, the lever is at the bottom end of the vertical through groove, and when the clamping protrusion is embedded in the lower clamping recess, the lever is in the horizontal through groove.

[0011] The utility model is further configured as follows: a stabilizing block which is fitted to the inner wall of the casing is arranged at the bottom end of the safety lock piece.

[0012] The utility model is further configured as follows: the lock ring is provided with a force-applying push plate for driving the lock ring to rotate.

[0013] The utility model is further configured as follows: the flip cover is rotatably connected with a lifting ring.

[0014] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a water cup with a rotating unlocking cover, which is more convenient and practical when used on the water cup.

[0015] The above technical purpose of the utility model is achieved through the following technical scheme: a water cup with a cover body that can be unlocked by rotation, comprising a cup body, wherein the opening end of the cup body is detachably connected to the cover body by a thread.

[0016] By adopting the above technical solution, when cleaning or injecting liquid, the cover body can be removed by screwing, and the flip cover can be directly flipped up when drinking. When used in a water cup, it is more convenient and practical.

[0017] To sum up, the utility model has the following beneficial effects: the safety lock plate and the lock ring respectively assume the two functions of locking and limiting, thereby ensuring the limiting force on the flip cover while effectively avoiding the increase of the force required for the opening and closing operation; the use of the lever in conjunction with the vertical through groove and the horizontal through groove not only realizes the locking and unlocking of the lock ring, but also has the technical effect of limiting the rotation angle range of the lock ring, providing convenience for the inward-turned hook to align with the notch; the safety lock plate realizes the limitation of two gears, namely the locking gear and the unlocking gear, through the upper clamping recess and the lower clamping recess in conjunction with the clamping protrusion, which provides convenience for the lever to align with the horizontal through groove under the premise of preventing the safety lock plate from sliding abnormally.

When the inverted hook 5 is aligned with the notch 7, the inverted hook 5 is outside the vertical projection of the hooked ring plate 6.

[0026] When the closure is in the closed state, the flip cover 2 is covered on the rotary cover 1, and the angle at which the locking ring 3 is located is that each inward-turning hook 5 is offset from the notch 7 and is hooked on the hooked ring plate 6, and the rotational activity of the locking ring 3 is limited by the safety locking piece 4, so that the flip cover 2 is restricted by the cooperation of the inward-turning hook 5 and the hooked ring plate 6, which has a larger restriction connection amount than the prior art, effectively ensuring the restriction force on the flip cover 2 and thus preventing it from being opened abnormally; when it needs to be opened, the safety locking piece 4 is adjusted to disengage it from the restriction on the rotational activity of the locking ring 3, and the locking ring 3 is rotated until each inward-turning hook 5 is aligned with the corresponding notch 7. At this time, the inward-turning hook 5 is disengaged from the vertical projection of the hooked ring plate 6, so that the flipping activity of the flip cover 2 is not restricted, and the flip cover 2 can be directly flipped up; in summary, the present application uses the safety locking piece 4 and the locking ring 3 to respectively assume the two functions of locking and restricting, thereby ensuring the restriction force on the flip cover 2 while effectively avoiding the increase in the force required for the opening and closing operation.

[0027] The safety lock plate 4 locks and unlocks the lock ring 3 in the following manner: Figure 1 , Figure 2 , Figure 3 As shown, the safety lock plate 4 is integrally formed or ultrasonically welded with the lever 8, and the lock ring 3 is integrally formed with a vertical through groove 9 and a horizontal through groove 10 that are clearance-matched with the lever 8; the horizontal through groove 10 has a locking end 11 and an unlocking end 111, and the vertical through groove 9 is connected to the locking end 11 of the horizontal through groove 10; when the lock ring 3 needs to be locked, the lock ring 3 is rotated until the lever 8 is at the locking end 11 of the horizontal through groove, and force is applied to the lever 8 to slide the safety lock plate 4 downward until the lever 8 is at the bottom end of the vertical through groove 9, thereby limiting the rotational activity of the lock ring 3 through the abutment and cooperation between the lever 8 and the groove wall of the vertical through groove 9, that is, locking the lock ring 3; when the lock ring 3 needs to be unlocked 3, force is applied to the lever 8 to slide the safety lock plate 4 upward until the lever is disengaged from the vertical through slot 9, and the lock ring 3 can be rotated normally; it should be noted that, it is only necessary to limit the length of the horizontal through slot 10 to limit the rotation angle range of the lock ring 3, that is, when the lever 8 is at the unlocking end 111 of the horizontal through slot 10, the inward hook 5 is aligned with the notch 7, which effectively improves the user's convenience; in summary, the present application utilizes the lever 8 in conjunction with the vertical through slot 9 and the horizontal through slot 10, which not only realizes the locking and unlocking of the lock ring 3, but also has the technical effect of limiting the rotation angle range of the lock ring 3, and provides convenience for the inward hook 5 to align with the notch 7.

[0028] The safety lock piece 4 is slidably connected to the flip cover 2 in the following manner: Figure 3 , Figure 4 As shown, the flip cover 2 is assembled with a cover 12 for the safety lock plate 4 to slide up and down.
