[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] See also Figures 1 to 9 As shown, in the embodiment of the utility model, a cup cover for preventing misuse includes a base 1, which is cylindrical. The base 1 is sealed and mounted on the cup body 5 by threaded connection or bayonet fastening. A drinking hole 11 is also provided on the base 1. The drinking hole 11 includes a mounting hole 111 provided on the base 1, and a hose 112 for sucking water from the inside of the cup body 5 is coaxially and sealedly installed in the mounting hole 111. A pressure relief hole 12 is also provided on the base 1.

[0035] A torsion spring seat is installed at the edge of the base 1, and the hinge axis of the torsion spring seat is arranged perpendicular to the axis of the base 1. A concave flip cover 2 is hingedly arranged on the torsion spring seat, and a pressing plate 21 is arranged in a concave cavity formed by the flip cover 2. A downward positioning piece is installed at the cantilever end of the flip cover 2, and a lock hole 22 is opened on the positioning piece.

[0036] A cylindrical positioning sleeve 3 is installed on the base 1, and a pressing plate 31 is hinged in the sleeve cavity of the positioning sleeve 3 through a rocker hinge shaft 33. The axis of the rocker hinge shaft 33 and the axis of the positioning sleeve 3 are perpendicular to each other. The pressing plate 31 is divided into two by the rocker hinge shaft 33, and the upper end of the pressing plate 31 constitutes an upturned end 312, and the lower end of the pressing plate 31 constitutes a pressing end 311. A locking tongue 3121 is installed on the inner side of the upturned end 312, and the upper end surface of the locking tongue 3121 is an inclined surface 39. A return spring as an elastic member 34 is also compressed and arranged between the pressing end 311 and the side wall of the base 1. A avoidance hole 32 is also opened at the tail end of the positioning sleeve 3.

[0037] When in use, the flip cover 2 is pressed downward, and the flip cover 2 rotates downward around the axis, and the straw is pressed against the upper end surface of the base 1 under the action of the pressing plate 21. The pressing plate 21 presses the straw against the pressure relief hole 12, and while closing the pressure relief hole 12, the straw is deformed and sealed. The positioning piece passes through the avoidance hole 32 and contacts the inclined surface 39 of the lock tongue 3121. Under the action of continuous downward pressure, the lock tongue 3121 retreats. After the positioning piece passes over the lock tongue 3121, the lock tongue 3121 is reset under the action of the reset spring and inserted into the lock hole 22 to lock the flip cover 2, so that the flip cover 2 is in a closed state.

[0038] See also Figures 3 to 5 As shown, the sleeve opening of the positioning sleeve 3 is folded outward to form a circular ring-shaped folded edge 35, and a rotary cover is rotatably installed at the sleeve opening of the positioning sleeve 3. The rotary cover includes a U-shaped card 4, the inner side of the U-shaped card 4 is recessed inward to form a U-shaped groove 41, and the folded edge 35 is coaxially rotatably slidably arranged in the U-shaped groove 41, so that the U-shaped card 4 rotates around the axis of the positioning sleeve 3.

[0039] The inner sides of both ends of the U-shaped card 4 are mounted to abut against protrusions 42 on the outer surface of the positioning sleeve 3, and the two protrusions 42 cooperate with each other to form a rotating shaft for the U-shaped card 4 to swing on the positioning sleeve 3. Two upper positioning anchor points 36 and two lower positioning anchor points 37 are symmetrically arranged on the outer surface of the positioning sleeve 3 with the axial symmetry plane of the positioning sleeve 3.

[0040] like Fig.10 and Fig.11 As shown, another variant structure of the U-shaped card 4 is a complete round cover. Two protrusions 42 are provided at corresponding positions on the inner side of the round cover, and a U-shaped groove with a U-shaped cross section is provided on the inner wall of the round cover, so that the round cover can be rotatably installed on the positioning sleeve 3. At the same time, the sealing end of the round cover forms a limit plate 43. By rotating the round cover, the same function as the U-shaped card 4 can be achieved.

[0041] like Figure 7 As shown, when the limit plate 43 abuts against the upturned end 312 of the pressing plate 31, the two lower positioning anchor points 37 abut against the corresponding protrusions 42 on the U-shaped card 4 in an offset manner up and down; at the two lower abutment points formed, the direction of the force exerted by the protrusions 42 on the lower positioning anchor points 37 is along the circumference of the positioning sleeve 3, and the directions of the forces of the two lower abutment points are opposite to each other.

[0042] like Figure 8 As shown, when the limit plate 43 abuts against the pressing end 311 of the pressing plate 31, the two lower positioning anchor points 37 abut against the corresponding protrusions 42 on the U-shaped card 4 in an offset manner up and down; at the two upper abutment points formed, the direction of the force generated by the protrusions 42 on the upper positioning anchor points 36 is along the circumference of the positioning sleeve 3, and the directions of the forces of the two upper abutment points are opposite to each other.

[0043] A semicircular limiting plate 43 is installed on the outer side of the U-shaped card 4. The limiting plate 43 rotates to the upturned end 312 of the pressing plate 31 and contacts the outer side of the upturned end 312; the limiting plate 43 rotates to the pressing end 311 of the pressing plate 31 and contacts the outer side of the pressing end 311, and can press the pressing end 311 downward to make the upturned end 312 tilt up.

[0044] The outer end surface of the folded edge 35 is a wedge surface inclined from the upturned end 312 of the pressing plate 31 to the pressing end 311 of the pressing plate 31; the wedge surface includes a vertical plane 38 located on the upper side of the axis of the rocker hinge shaft 33, and a lower inclined surface 39 located on the lower side of the axis and gradually inclined toward the base 1, and the outer side surface of the pressing plate 31 in the normal state and the inner side surface of the limit plate 43 in the normal state are both coplanar with the vertical plane 38.

[0045] When in use, first rotate the U-shaped card 4 to the uppermost end. At this time, the outer side of the pressing plate 31 is in a vertical state, and the outer side of the pressing plate 31 and the inner side of the limiting plate 43 are pressed against each other. When the pressing end 311 is pressed downward, the upward end 312 will not be lifted, and the flip cover 2 is also in a closed state. At this time, the inner side of the limiting plate 43 is also in contact with the vertical surface 38, and the U-shaped card 4 will not move along the axial direction of the positioning sleeve 3. Figure 7 As shown, the central angle between the two protrusions 42 is greater than 180 degrees, so that the positioning sleeve 3 can be covered without slipping; the two protrusions 42 are respectively abutted against the two lower positioning anchor points 37, so that the U-shaped card 4 will not rotate or shake.

[0046] When the flip cover 2 needs to be opened to drink water, the U-shaped card 4 is rotated 180 degrees, and the U-shaped card 4 is rotated to the bottom. The inner side surface of the limit plate 43 and the outer side surface of the pressing end 311 are separated from each other, and the inner side surface of the limit plate 43 and the outer side surface of the pressing end 311 are in contact with each other. There is a certain distance between the inclined surfaces 39 on the upper and lower sides of the positioning sleeve 3 and the inner side surface of the limit plate 43, so that the limit plate 43 can be pressed inward. Figure 8 As shown, at this time, the two protrusions 42 and the two upper positioning anchor points 36 abut against each other, thereby limiting the rotation of the U-shaped card 4 around the axis of the positioning sleeve 3. Then, the outer side of the limit plate 43 is pressed, and the U-shaped card 4 uses the protrusion 42 as an axis to drive the pressing end 311 of the pressing plate 31 to rotate inward around the axis, and the upward end 312 of the pressing plate 31 is tilted at the same time, and the lock tongue 3121 and the lock hole 22 are separated from each other. The flip cover 2 is flipped up under the reaction force of the torsion spring seat and the hose 112. At this time, the hose 112 is tilted, and the pressure relief hole 12 is opened, and water can be drunk. After drinking water, press down to lock the flip cover 2, and reset the U-shaped card 4 in the opposite direction.

[0047] During drinking, the U-shaped card 4 can rotate to a certain angle as long as it can be opened. The upper positioning anchor point 36 and the lower positioning anchor point 37 may not be provided on the outer surface of the positioning sleeve 3, and the rotation angle of the U-shaped card 4 may be limited simply by friction braking. That is, the position of the U-shaped card 4 when pressing the pressing end 311 of the pressing plate 31 can be locked.

[0048] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
