A sealing rubber pad for abutting against the upper end surface of the cup body is provided on the upper end surface of the concave annular groove.

[0008] Preferably, a chute is opened on the fixing plate. Limiting grooves are opened on both sides inside the chute. The upper end of the sliding support plate is inside the chute and is provided with limiting blocks slidably connected with the limiting grooves. The threaded rod is threadedly engaged with the fixing plate and is rotatably connected to the outside of the sliding support plate. A rotating handle is provided at the outer end of the threaded rod.

[0009] Preferably, the inner side of the anti-slip clamping plate is an arc surface structure adapted to the outer circle of the cup body, and a rubber anti-slip pad is arranged on the inner side of the anti-slip clamping plate.

[0010] Preferably, a groove is formed on the upper end surface of the cover body, an annular groove is formed on the inner wall of the groove, a support rod is rotatably connected in the annular groove, and a hanging ring is connected by the two support rods.

[0011] Preferably, a drinking port is arranged on the upper end surface of the cover body, the drinking port is sealed by a sealing cover, and the sealing cover is connected to the cover body by a connecting rope.

[0012] Preferably, a plurality of anti-slip protrusions are arranged on the outer side surface of the cover body and the outer side surface of the sealing cover.

[0013] The utility model has at least the following beneficial effects:

[0014] 1. During use, the external thread structure arranged on the lower end surface of the cover body is adapted to the internal thread structure inside the cup body for connection, realizing the initial rotational connection between the cover body and the cup body. Then, by rotating the threaded rod, the sliding support plate is driven to slide inward in the chute until the anti-slip clamping plate contacts and locks with the outer side of the cup body, thus realizing the further locking of the cover body and the cup body and preventing the situation of falling off.

Detailed implementation manners

[0022] The following will cooperate with the drawings and embodiments to elaborate on the implementation manners of the present application, so as to fully understand how the present application uses technical means to solve technical problems and achieve the realization process of technical effects and implement accordingly.

[0023] As Figures 1-5 shown, the plastic coffee cup lid that is not easily loosened provided in this embodiment includes a cover body 1. Below the outer side surface of the cover body 1, there is an external thread structure 2 for threaded screwing connection with the cup body. Below the outer side surface of the cover body 1, there is a concave annular groove 7. The external thread structure 2 is on the surface of the concave annular groove 7. On the upper end surface of the concave annular groove 7, there is a sealing rubber pad 8 for abutting against the upper end surface of the cup body. The sealing rubber pad 8 is used to improve the sealing effect after the cover body 1 and the cup body are sealed;

[0024] Furthermore, as Figure 1 shown, on the upper end surface of the cover body 1, there is a groove 13. Inside the inner wall of the groove 13, there is an annular groove 14. In the annular groove 14, there is a support rod 15 rotatably connected. Through two support rods 15, there is a hanging ring 16 connected. The setting of the annular groove 14 enables the rotation and angle adjustment of the hanging ring 16, so that the hanging ring 16 can adapt to hanging at different positions. At the same time, the setting of the groove 13 can fold and hide the hanging ring 16;

[0025] Even further, as Figure 1 shown, on the upper end surface of the cover body 1, there is a drinking port 17 for drinking water. The drinking port 17 is sealed by a sealing cover 18 to prevent water leakage. The sealing cover 18 is connected to the cover body 1 through a connecting rope 19 to prevent the sealing cover 18 from being lost;

[0026] On both sides of the upper end surface of the cover body 1, there is a locking mechanism. The locking mechanism includes a fixing plate 3 provided on the upper end surface of the cover body 1, a sliding support plate 4 slidably connected inside the fixing plate 3, an anti-slip clamping plate 5 provided below the inside of the sliding support plate 4, and a threaded rod 6 for pushing the sliding support plate 4;

[0027] Among them, a chute 9 is provided on the fixed plate 3, and limiting grooves 10 are provided on both sides inside the chute 9. The upper end of the sliding support plate 4 is located inside the chute 9 and is provided with limiting blocks slidably connected to the limiting grooves 10. The setting of the limiting blocks slidably connected to the limiting grooves 10 can prevent the sliding support plate 4 from falling off during sliding. The threaded rod 6 is threadedly connected to the fixed plate 3 and rotatably connected to the outside of the sliding support plate 4. A rotating handle 12 is provided at the outer end of the threaded rod 6. The rotating handle 12 facilitates the rotation of the threaded rod 6. Among them, after the locking mechanism needs to be locked with the cup body, by rotating the threaded rod 6, the sliding support plate 4 is driven to slide inward in the chute 9 until the anti-slip clamping plate 5 contacts and locks with the outside of the cup body, so as to further lock the cover body 1 and the cup body and prevent falling off;

[0028] Further, as Figure 5 shown, the inner side surface of the anti-slip clamping plate 5 is an arc surface structure adapted to the outer circle of the cup body. The arc surface structure can ensure that the anti-slip clamping plate 5 can better wrap and clamp the periphery of the cup body. A rubber anti-slip pad is provided on the inner side surface of the anti-slip clamping plate 5. The setting of the rubber anti-slip pad can further improve the anti-slip effect when the clamping plate 5 clamps;

[0029] Furthermore, as Figure 1 shown, a plurality of anti-slip protrusions 20 are provided on the outer side surface of the cover body 1 and the outer side surface of the sealing cover 18. The setting of the anti-slip protrusions 20 facilitates the rotation of the sealing cover 18 and the cover body 1 and plays an anti-slip effect.

[0030] As used in the specification and claims, certain terms are used to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in names as a way to distinguish components, but use the difference in functions of components as a criterion for distinction. As mentioned throughout the specification and claims, "comprising" is an open-ended term and should be interpreted as "including but not limited to". "Substantially" means within an acceptable error range. Those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0031] It should be noted that the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a commodity or system including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such commodity or system. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of another identical element in the commodity or system including the element.

[0032] The above description shows and describes several preferred embodiments of the present utility model. However, as previously mentioned, it should be understood that the present utility model is not limited to the forms disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications, and environments, and can be changed within the scope of the inventive concept described herein through the above teachings or the techniques or knowledge in the relevant field. Any changes and variations made by those skilled in the art without departing from the spirit and scope of the present utility model shall fall within the protection scope of the appended claims of the present utility model.
