Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0021] The following is in conjunction with the appendix Figure 1-4This application will be described in further detail.

[0022] This application discloses a leak-proof PET ultra-transparent milk tea cup lid, referring to... Figure 1 and Figure 2 , Figure 3 The cup includes a PET ultra-transparent milk tea cup body 1; a fixing ring 2 is rotatably connected to the top of the PET ultra-transparent milk tea cup body 1, a cup lid shell 3 is fixedly connected to the top of the fixing ring 2, a straw groove 4 is opened at the rear end of the top of the cup lid shell 3, a cup spout 5 is fixedly connected to the front end of the top of the cup lid shell 3, a cup stopper 6 is movably connected to the top of the cup spout 5, a handle 7 is fixedly connected to the front end of the top of the cup stopper 6, a pressing device 8 is fixedly connected to the middle part of the top of the cup lid shell 3, and a storage device 9 is movably connected to the bottom of the other side of the PET ultra-transparent milk tea cup body 1, and a sugar packet 10 is set inside the storage device 9; the pressing device 8 can provide a certain pressure to ensure a tight fit between the cup stopper 6 and the cup spout 5, prevent liquid leakage caused by external pressure or shaking, further strengthen the sealing effect, and prevent liquid from overflowing from the joint between the cup stopper 6 and the cup spout 5.

[0023] Reference Figure 4 The pressing device 8 is provided with a base 801, and a rotating shaft 802 is rotatably connected to the top of the base 801. The rotation of the rotating shaft 802 on the base 801 facilitates the rotation of the pull rod 804 on the fixed plate 803 around the rotating shaft 802. The rotation of the rotating shaft 802 facilitates the rotation of the pressing block 807.

[0024] Reference Figure 4 A fixed plate 803 is fixedly connected to the top of the rotating shaft 802, and a pull rod 804 is movably connected through the fixed plate 803; the pull rod 804 can be moved up and down to facilitate the movement of the lower pressure block 807.

[0025] Reference Figure 4 A fixed plate 805 is fixedly connected to the top of the pull rod 804, and a pull ring 806 is fixedly connected to the top of the fixed plate 805; by pulling the pull ring 806, the fixed plate 805 can be moved upward.

[0026] Reference Figure 4 A pressing block 807 is fixedly connected to the bottom of the pull rod 804, and a spring 808 is provided between the pressing block 807 and the fixing plate 803; the elasticity of the spring 808 facilitates the pressing block 807 to press down and fix the cup stopper 6.

[0027] Reference Figure 2 The storage device 9 is equipped with a drawer 901, and a handle 902 is fixedly connected to the other side of the drawer 901; by pulling the handle 902, the drawer 901 can be opened or closed.

[0028] Working principle: Pulling the pull ring 806 facilitates the upward movement of the fixed plate 805. The movement of the fixed plate 805 facilitates the upward movement of the pull rod 804. The movement of the pull rod 804 facilitates the upward movement of the lower pressure block 807. The rotation of the rotating shaft 802 on the base 801 facilitates the rotation of the pull rod 804 on the fixed plate 803 around the rotating shaft 802. The rotation of the rotating shaft 802 facilitates the rotation of the lower pressure block 807. When the cup stopper 6 is rotated to the top, the pull ring 806 is released. The elasticity of the spring 808 facilitates the lower pressure block 807 to provide a certain pressure to the cup stopper 6, ensuring a tight fit between the cup stopper 6 and the cup spout 5, preventing liquid leakage caused by external pressure or shaking, further strengthening the sealing effect, and preventing liquid from overflowing from the joint between the cup stopper 6 and the cup spout 5.
