DETAILED DESCRIPTION

[0023] 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.

[0024] See also Figure 1-4A disposable environmentally friendly and degradable cup cover that is easy to use, comprising a cup cover body 1, a straw through hole 2, a drinking through hole 3 and a self-locking device, wherein the straw through hole 2 is provided at the middle of the top of the cup cover body 1, and the drinking through hole 3 is provided at one end of the top wall of the cup cover body 1. The self-locking device comprises a moving groove 4, a positioning block 5, a guide block 6, a guide groove 7, a spring 8 and a pull block 9, an annular groove 10 is provided at the bottom wall of the cup cover body 1, and the moving groove 4 that passes through the annular groove 10 is provided at one end of the cup cover body 1, and the positioning block is slidably installed in the moving groove 4 5, the lower part of one end of the positioning block 5 close to the annular groove 10 is designed as an inclined surface, the front and rear ends of the movable groove 4 are provided with the guide groove 7, the guide block 6 is slidably installed in the guide groove 7, the side walls corresponding to the two groups of guide blocks 6 are respectively fixedly connected with the front and rear side walls of the positioning block 5, the end of the guide block 6 close to the annular groove 10 is installed with the spring 8, the end of the spring 8 away from the guide block 6 is fixedly connected with the side wall of one end of the guide groove 7 close to the annular groove 10, the positioning block 5 is away from the annular groove 10 The pull block 9 is fixedly installed at one end. In this embodiment, when the cup cover body 1 needs to be installed on the cup body during use, the cup cover body 1 is first gently pressed onto the cup body so that the annular groove 10 at the bottom end of the cup cover body 1 is aligned with and in contact with the edge of the cup body. During the pressing process, as the cup cover body 1 gradually approaches the cup body, the inclined surface design of the positioning block 5 (installed in the movable groove 4) will first contact the edge of the cup body. Due to the effect of the inclined surface, the positioning block 5 will be subjected to a force sliding toward the inside of the movable groove 4. As the positioning block 5 slides, the guide block 6 fixedly connected thereto will also slide in the guide groove 7. When the cup cover body 1 needs to be unlocked, it is necessary to gently pull the pull block 9 so that the pull block 9 drives the positioning block 5 away from the edge of the cup body to complete the unlocking of the cup body.

[0025] During actual use, the movement of the slider is further guided. In this embodiment, a guide rod 11 is fixedly installed in the guide groove 7, and the guide block 6 is slidably installed on the guide rod 11. The guide rod 11 provides a clear path and direction for the movement of the slider, so that the slider can remain relatively stable during the movement and is not easy to deviate from the predetermined trajectory.

[0026] In actual use, it is further convenient to seal the drinking through hole 3. In this embodiment, a cup plug 12 is installed on the drinking through hole 3, and a limiting plate 13 is installed on the top of the cup plug 12. A connecting rib 14 is installed on the top of the limiting plate 13. The other end of the connecting rib 14 is connected to the top wall of the cup cover body 1. The design of the cup plug 12 enables the user to easily open and close the drinking through hole 3 to achieve rapid sealing and opening. When drinking is not needed, the cup plug 12 only needs to be pushed into the drinking through hole 3 to achieve a sealing effect to prevent liquid leakage or dust from entering. When drinking is needed, the cup plug 12 only needs to be gently pulled out. The combination of the limiting plate 13 and the connecting rib 14 enables the cup plug 12 to be more stably positioned when inserted into the drinking through hole 3, and is not easy to loosen or fall off.

[0027] In actual use, in order to further prevent the straw from entering the straw through hole 2 and causing the liquid therein to overflow, in this embodiment, a sealing ring 15 is installed on the inner side wall of the straw through hole 2, and a sealing paper 16 is installed in the sealing ring 15. When the straw is inserted into the straw through hole 2, the straw punctures the sealing paper 16 and can fit tightly against the side wall of the sealing ring 15, effectively preventing the liquid from overflowing from the gap between the straw and the straw through hole 2. Such enhanced sealing can ensure that the drink will not leak due to the loose fit between the straw and the through hole during carrying or use.

[0028] In actual use, the sealing performance of the cup cover body 1 is further improved. In this embodiment, a sealing gasket 17 is installed in the annular groove 10. The sealing gasket 17, as a component specially used for sealing, can fill the tiny gap between the cup cover body 1 and the cup, thereby effectively preventing liquid or gas from leaking through these gaps. This design enables the cup cover to form a tighter seal after installation, thereby improving the overall sealing effect.

[0029] In actual use, the stability of the installation of the cup cover body 1 is further ensured. In this embodiment, two groups of self-locking devices are provided and are respectively installed on the left and right ends of the cup cover body 1. The two groups of self-locking devices are respectively located on the left and right ends of the cup cover body 1, forming a double locking mechanism. This design can significantly increase the connection strength between the cup cover body 1 and the cup body, making the cup cover body 1 less likely to fall off or loosen when subjected to external force. This double insurance improves the overall stability of the cup cover body 1 and ensures the sealing and safety of the drink.

[0030] In actual use, in order to further prevent liquid from spilling, in this embodiment, a retaining ring 18 is installed at the top edge of the cup cover body 1, and the retaining ring 18 can block the accidentally spilled liquid and prevent it from spilling to the surroundings.

[0031] Preferably, in this embodiment, the cup lid body 1 is made of degradable material, which can be gradually decomposed into harmless substances such as carbon dioxide, water and other biomass by the action of microorganisms in the natural environment, thereby reducing pollution and damage to the environment. This helps to solve the problem of white pollution caused by traditional plastic cup lids that are difficult to degrade and remain in the environment for a long time.

[0032] In order to explain in detail the possible application scenarios, technical principles, specific schemes that can be implemented, and the purposes and effects that can be achieved, the following is a detailed description of the specific embodiments listed in conjunction with the accompanying drawings. The embodiments described herein are only used to more clearly illustrate the technical solutions of the present application, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present application.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
