[0018] The technical solution of the utility model is further described in detail below in conjunction with specific implementation methods.

[0019] like Figures 1 to 4As shown, in the embodiment of the utility model, a self-locking cup cover is used for sealing and installing on the cup body, comprising a cover body 1, a threaded portion rotatably installed with the cup body is provided at the bottom of the cover body 1, a group of protruding baffles 2 are respectively provided on both sides of the upper end surface of the cover body 1, a drinking port 102, a pipe insertion port 101 and a negative pressure port 103 are provided on the end surface of the upper end surface of the cover body 1 located between the two groups of protruding baffles 2, a sealing plug is fixedly plugged in the pipe insertion port 101, a sealing plate 3 is rotatably installed on the cover body 1, two groups of sealing protrusions are installed on the bottom end surface of the sealing plate 3, the two groups of sealing protrusions are respectively used to seal the drinking port 102 and the negative pressure port 103, a locking plate 4 is slidably installed on the side of the sealing plate 3 away from the sealing protrusion, the locking plate 4 is elastically connected to the sealing plate 3, locking protrusions are respectively provided on both sides of the locking plate 4, and locking grooves 201 for locking the locking protrusions to limit the position are provided at the near ends of the two groups of protruding baffles 2;

[0020] When the sealing plate 3 is rotated and buckled on the cover body 1, the locking protrusion slides into the locking groove 201 to lock the sealing plate 3. Specifically, in the utility model, a limiting protrusion is provided in the locking groove 201. When the locking protrusion slides into the locking groove 201, the limiting protrusion can limit the sliding of the locking protrusion. When unlocking, the locking plate 4 is moved by human sliding. At this time, the limiting protrusion cannot limit the sliding of the locking protrusion from the locking groove 201, and the sealing plate 3 can be turned over by human power to open;

[0021] At the same time, the height of the protruding baffle plate 2 is higher than the height of the locking plate 4 in the sealed state, thereby providing force protection for the locking plate 4 to prevent it from sliding due to force from external objects.

[0022] like Figure 1 and Figure 2 As shown, in the embodiment of the utility model, the protruding baffle plate 2 is a hollow structure, which reduces the mass of the protruding baffle plate and makes the cover body 1 lighter.

[0023] like Figure 1 and Figure 2 As shown, in the embodiment of the utility model, a group of connecting columns are respectively provided on both sides of the sealing plate 3, and the near ends of the two groups of protruding baffles 2 are provided with mounting holes for rotatable connection of the connecting columns, and the sealing plate 3 rotates around the connecting columns.

[0024] like Figure 1As shown, in the embodiment of the utility model, the end of the locking plate 4 is provided with a force strip for a person to pull and apply force, and a cavity is provided between the locking plate 4 and the sealing plate 3, and a coil spring 5 is installed in the cavity. The two ends of the coil spring 5 are respectively fixedly connected to the locking plate 4 and the sealing plate 3. When the locking plate 4 is pulled and displaced and slid by a person, the coil spring 5 contracts and resets after the human force is released. Of course, the coil spring 5 can also be replaced by other elastic parts, such as connecting spring leaves, etc.

[0025] like Figure 1 As shown, in the embodiment of the utility model, a buckle plate 301 for a person to buckle is provided at the end of the sealing plate 3.

[0026] In summary, the utility model provides a locking plate 4 at the upper end of the sealing plate 3 on the cover body 1, and elastically and slidingly connects the locking plate 4 to the sealing plate 3. When the sealing plate 3 is rotated and buckled on the cover body 1, the locking protrusion slides into the locking groove 201 to lock the sealing plate 3. At the same time, the protruding baffles on both sides of the cover body 1 protect the locking plate 4 in the sealed state, thereby solving the problem that the thermos cup cover in the prior art usually does not have a locking structure for locking the pressing part, resulting in the pressing part being often accidentally pressed to open the cup cover.

[0027] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
