[0035] In order to make the technical scheme of the utility model more clear, the following will combine the drawings of the utility model to make a detailed description. Figures 1 to 9 The specific embodiments described in the specification are only for the purpose of explaining the utility model, and are not intended to limit the protection scope of the utility model.

[0036] The utility model is a kind of flip cup cover with lock catch button, including cover main body 1, upper cover 2, button 3 and lock catch 4;Wherein the top of cover main body 1 is equipped with up and down through drinking water mouth 11, the rear end of upper cover 2 is hinged to the rear end of cover main body 1 for opening and closing drinking water mouth 11, button 3 is radially inside and outside movable and arranged in the assembly cavity 12 of the front end of cover main body 1 for buckling upper cover 2, lock catch 4 is up and down sliding and arranged on the outside of button 3 for locking or unlocking the inside and outside movement of button 3;Lock catch 4 slides down, in unlocking state, lock catch 4 releases the locking of button 3, press button 3, i.e. upper cover 2 pops open and opens drinking water mouth 11 and is in open state;Button 3 buckling upper cover 2 closes drinking water mouth 11, in closing state;At this time, lock catch 4 slides up again, button 3 is locked and limited to press inwards and move, in closing and locking state.

[0037] Specifically, the rear end of the cover body 1 is provided with a hinge lug 14, and the rear end of the upper cover 2 is correspondingly provided with a connecting portion 21, and a pin shaft 7 is arranged through the hinge holes of the hinge lug 14 and the connecting portion 21, so that the upper cover 2 is hinged to the cover body 1; and a torsion spring 8 is further sleeved on the pin shaft 7 and arranged between the connecting portion 21 and the cover body 1, so as to provide elastic force for opening of the upper cover 2; when the button 3 is pressed, the upper cover 2 is opened by the elastic force of the torsion spring 8.

[0038] Specifically, the lower surface of the upper cover 2 is further provided with a sealing element 6 corresponding to the drinking water opening 11, so as to facilitate sealing of the drinking water opening 11 in the closed state.

[0039] Specifically, the two side walls of the assembly cavity 12 are symmetrically provided with movable grooves 121, the inner wall extends radially outward, and the blocking edges 122 and the first spring columns 123 are sequentially arranged from bottom to top, and the avoiding grooves 124 are arranged between the bottom wall and the blocking edges 122; the two sides of the button 3 are symmetrically provided with limiting buckles 31, which are limited to move in the movable grooves 121, so that the button 3 cannot be separated from the assembly cavity 12; the button spring 5 is further arranged between the button 3 and the inner wall of the assembly cavity 12, so as to provide elastic restoring force for the button 3, and the second spring column 32 is further arranged on one side of the button 3, and the two ends of the button spring 5 are sleeved on the first spring column 123 and the second spring column 32 respectively, so as to avoid the problems of separation, skew and the like of the button spring 5 in the use process, which causes the button 3 to be stuck.

[0040] Specifically, the upper end of the button 3 is further provided with a radial outward hook 33, and the hook 33 and the main body of the button 3 form a hook groove 34; the upper cover 2 is correspondingly provided with a radial inward reverse hook 22; the reverse hook 22 falls into the hook groove 34 and is buckled with the hook 33; when the button 3 is pressed, the button 3 moves inward, the hook 33 is separated from the reverse hook 22, the reverse hook 22 is separated from the hook groove 34, and the upper cover 2 can be opened by the action of the torsion spring 8.

[0041] Further, the upper end of the hook 33 and the lower end of the reverse hook 22 are both guide inclined surfaces; at this time, when the upper cover 2 needs to be closed again, only the upper cover 2 needs to be pressed downward, the guide inclined surfaces of the reverse hook 22 and the hook 33 drive the button 3 to move inward, so that the upper cover 2 can continue to move downward, until the reverse hook 22 falls into the hook groove 34, the button 3 is reset under the action of the button spring 5, the hook 33 is buckled with the reverse hook 22, and the upper cover 2 can be closed to seal the drinking water opening 11.

[0042] Specifically, in one embodiment, two long holes 35 are symmetrically arranged on the body of the button 3; the lock catch 4 comprises a sliding piece 41 and a sliding member 42; the sliding member 42 is arranged correspondingly to the long hole 35 and comprises a sliding rod 421 and an anti-pulling-off 422, and the anti-pulling-off 422 is a protrusion on one end of the sliding rod 421; the anti-pulling-off 422 and the sliding piece 41 are respectively arranged on the two sides of the button 3, the sliding rod 421 passes through the long hole 35, and the other end is fixedly connected with the sliding piece 41; through the above arrangement, the lock catch 4 can slide up and down on the button 3.

[0043] Further, the left and right sides of the button 3 are also symmetrically provided with guide grooves 36, and the sliding piece 41 of the lock catch 4 is correspondingly provided with guide blocks 43 on both sides, which are slidingly arranged in the guide grooves 36; through the above arrangement, the sliding stability of the lock catch 4 can be further ensured, and phenomena such as skewing and jamming do not occur.

[0044] Further, one side wall of the long hole 35 is sequentially provided with a first positioning recess 351 and a second positioning recess 352 from top to bottom; the side wall of the sliding rod 421 is provided with a positioning protrusion 423; when the lock catch 4 slides up and down, the positioning protrusion 423 falls into the first positioning recess 351 and the second positioning recess 352, respectively in the locked state and the unlocked state; through the above arrangement, the concave-convex cooperation can provide the sliding-in-place prompt and the state maintenance of the lock catch 4.

[0045] In another embodiment, the two side walls of the body of the button 3 are symmetrically provided with slide grooves 38; the lock catch 4 comprises a sliding piece 41 and a sliding member 42; the sliding member 42 is arranged correspondingly to the slide groove 38 and comprises slide buckles 45 symmetrically arranged on the left and right sides of the sliding piece 41, which are arranged in the slide groove 38 in a manner of limiting up and down sliding.

[0046] Further, the bottom wall of the slide groove 38 is provided with a positioning protrusion 423, and the side wall of the slide buckle 45 is sequentially provided with a first positioning recess 351 and a second positioning recess 352 from top to bottom; when the lock catch 4 slides up and down, the positioning protrusion 423 falls into the first positioning recess 351 and the second positioning recess 352, respectively in the locked state and the unlocked state.

[0047] Specifically, the sliding piece 41 of the lock catch 4 is outwardly protruded at the lower end to form a stopper 44; in the locked state, the stopper 44 corresponds to the stop edge 122 of the assembly cavity 12, and under the blockage of the stop edge 122, the button 3 will be limited from being pressed inward; in the unlocked state, the stopper 44 is staggered with the stop edge 122 and corresponds to the avoidance groove 124, and when the button 3 moves inward, the stopper 44 of the lock catch 4 is inserted into the avoidance groove 124.

[0048] Specifically, the upper side of the stop portion 44 is further provided with a clamping point 46, and the lower end of the button 3 is correspondingly provided with a concave point 37. In the locked state, the clamping point 46 falls into the concave point 37. This structure has a directional effect, which can further ensure that the lock catch 4 and the button 3 do not move relative to each other, and ensure the relative position between the lock catch 4 and the button 3.

[0049] It should be further explained that when the upper cover 2 is buckled with the button 3 and is in the closed state, the lock catch 4 is slid upward and is in the locked state. The upper end edge of the sliding sheet 41 is also corresponded with the upper cover 2, that is, the upper end edge of the sliding sheet 41 is blocked by the upper cover 2, and the inward movement thereof is limited. This design can further ensure that the upper cover 2 keeps the drinking water opening 11 closed, and avoids accidental opening in the locked state.
