         [0028]      FIG. 1  and  FIG. 2  show a stereoscopic schematic diagram of one embodiment of a cup cover according to the utility model and an exploded schematic diagram thereof on the same direction, wherein the cup cover includes a cover body  100  and a rotating member  200  arranged on the cover body. In the embodiment, the bottom of the cover body  100  is provided with an opening, the rotating member  200  is arranged above the cover body  100 . To be specific, a step surface  103  exists between the top part  101  and the bottom part  102  of the cover body  100 , and the diameter of the top part  101  is less than that of the bottom part; moreover, the rotating member  200  is preferably a cylindrical structure with an opening below, and sleeved on the top part  101  of the cover body  100 , thus forming an entirety seemingly. 
         [0029]    The rotating member  200  may be of other shapes, such as a plate like structure or lumpy structure; and the rotating member  200  may also be connected with the cover body  100  using other manners. 
         [0030]    The rotating member  200  is provided with a clamping hook  201 . Preferably, the clamping hook  201  is arranged at the inner surface of the top plate of the rotating member, and protrudes out vertically towards the down side. Correspondingly, the top plate of the cover body  100  is provided with a structure for the clamping hook  201  to traverse. In the embodiment, the above-mentioned structure is a limiting slot  104 , and the limiting slot  104  may allow the clamping hook  201  to traverse the top plate of the cover body  100  and stretch into the inner chamber of the cover body  100 . 
         [0031]    The rotating member  200  and the clamping hook  201  may integrally rotate relative to the cover body  100 . Meanwhile, due to the limiting effect of the limiting slot  104  on the clamping hook  201 , the clamping hook  201  can only move between one end (the first position) and the other end (second position) of the limiting slot  104 . 
         [0032]    In order to ensure that the rotating member  200  not only can rotate relative to the cover body  100  but also can be not separated from the cover body, the inside surface of the rotating member  200  is provided with a turn of bulge  202 , the outside surface of the top part  101  of the cover body  100  is provided with a turn of recess  105 ; when the rotating member  200  is sleeved on the cover body  100 , the bulge  202  is buckled in the recess  105 . 
         [0033]    A horizontal connecting arm  106  protrudes out from the side wall of the cover body  100 , the tail end of the connecting arm  106  is provided with a hinging seat  107 , and the cup cover  100  is provided with a locking bore  108  with respect to the other side of the connecting arm  106 . 
         [0034]    Furthermore, the inside of the cover body  100  is further provided with a sealing gasket  300  for sealing the bubbler. 
         [0035]      FIG. 3  shows a cross-sectional view of the cup cover according to the utility model, wherein the cross section is a vertical plane that passes through the axle center of the cover body  100  and also passes through the center of the clamping hook  201 . It can be known from the figure that the rotating member  200  is sleeved on the cover body  100 , and the two are connected through the bulge and the recess. Two clamping hooks  201  are preferred, which are distributed symmetrically by taking the center of the rotating member  200  as the axis, and meanwhile, two limiting slots are also arranged on the cover body  100  correspondingly. 
         [0036]    The sealing gasket  300  is then buckled on the inner surface of the top plate of the cover body  100  through a buckling position. 
         [0037]      FIG. 4  shows a top view of one embodiment of the cover body  100  according to the utility model, wherein two limiting slots  104  are arranged along the motion route of the clamping hook  201 , i.e., the limiting slots are distributed in a circular arc. One end of the limiting slot  104  is provided with a bulge  1041 , and the bulge is configured to vertically insert or pull out the clamping hook  201 . 
         [0038]      FIG. 5  shows a stereoscopic schematic diagram of one embodiment of a cup according to the utility model, wherein the cup includes a cup body  400  and the cup cover above. In the figure, the cup cover is under an open state and the rotating member is hidden, and only a part of the cup body  400  is shown. The top of the cup body  400  is provided with a bubbler  401 , an edge  402  protrudes out from the periphery of the bubbler  401 , and the cup cover is articulated on the cup body  400  through a hinging seat  107 , so that the cup cover can rotate relative to the cup body  400  to cover or uncover the bubbler  401 . 
         [0039]      FIG. 6  shows a cross-sectional view of the cup according to the utility model when the cup cover is unlocked, wherein the cross section is a horizontal plane parallel to the top surface of the cup body  400 , and meanwhile, the cross section passes through the top side of the bubbler  401  and shows the clamping hook  201  in a cross-sectional manner, wherein the sealing gasket is hidden in the figure. It can be known from the figure that when the cup cover is just covered on the cup body, the clamping hook  201  is located at one end (i.e., the first position) of the limiting slot; at this moment, the clamping hook  201  is located outside the edge  402 , i.e., not contacted with the edge  402 , so that the clamping hook  201  may stretch into the lower side of the edge  402 . 
         [0040]      FIG. 7  shows a cross-sectional view of the cup according to the utility model when the cup cover is locked, wherein the position of the cross section is unchanged. It can be known from the figure that the clamping hook  201  moves to the other end (i.e., the second position) of the limiting slot through rotating; at this moment, the clamping hook  201  is located below the edge  402  yet, so that the locking between the cup cover and the cup body is implemented; meanwhile, the sealing gasket which is not shown is tightly pressed on the bubbler  401  to seal the cup. 
         [0041]    In order to realize the foregoing objects, the edge  402  in the embodiment is distributed along a rectangle. That is to say, the cross section of the bubbler is a rectangle. In this manner, when the clamping hook  201  is located at the first position, the clamping hook is just located at the two ends of the long side of the rectangle. Because the width of the rectangle is less than the diameter of the motion track of the clamping hook  201 , the clamping hook  201  and the edge  402  are mutually separated; however, when the clamping hook  201  is located at the second position, the clamping hook is just distributed along the diagonal line of the rectangle; at this moment, the distance between the edges  402  is greater than the diameter of the minimum motion track of the clamping hook  201  yet; therefore, the clamping hook  201  can be limited. 
         [0042]    Of course, the distribution of the edge  402  is not limited to the above embodiment; for example, the edge  402  may be only distributed at the two ends of the long side of the rectangle; and the edge  402  may even be replaced by an independent buckling position. 
         [0043]    In order to lock the cup cover more preferably, referring to  FIG. 5 , the position of the cup body  400  corresponding to the locking bore is provided with a locking plate  403 ; when the cup cover covers the bubbler  401 , the locking bore is just aligned with the locking plate  403 , and the locking plate  403  can be inserted into the locking bore through moving along the horizontal direction. 
         [0044]    The above is specific explanations to the preferred embodiments of the utility model, but the utility model is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without departing from the spirit of the utility model, and these equivalent modifications or substitutions shall all fall within the scope defined by the claims of the present application.
