[0003] In an existing four-leaf clover pattern folding cup lid structure, when workers use most of the cup lids, the folding cover plate is simply inserted into the cover plate, which affects the installation stability between the cover plate and the folding cover plate. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a four-leaf clover pattern folding cup lid structure.

[0005] This utility model is achieved by the following technical solution: a four-leaf clover pattern folding cup lid structure, including a four-leaf clover pattern folding cup lid, the front of the four-leaf clover pattern folding cup lid is provided with a positioning slot, and the top of the four-leaf clover pattern folding cup lid is fixedly connected with a four-leaf clover pattern frame. The clover-patterned folding cup lid is internally fixedly connected to a secondary positioning sleeve, and internally fixedly connected to a primary positioning sleeve. A folding connecting plate is fixedly connected to the rear end of the clover-patterned folding cup lid, and a clover-patterned cover is fixedly connected to the rear end of the folding connecting plate. A positioning frame is fixedly connected to the top of the clover-patterned cover, a primary positioning pin is fixedly connected to the top of the clover-patterned cover, a secondary positioning pin is fixedly connected to the top of the clover-patterned cover, and a folding cover plate is fixedly connected to the rear end of the clover-patterned cover.

[0006] With the above technical solution, after the folding cover is inserted into the positioning slot, its edge fits tightly with the top of the cup lid, forming a triple leak-proof barrier, which is especially suitable for scenarios where liquid beverages are contained.

[0007] As a further improvement to the above solution, the number of the secondary positioning sleeves is set to two, and the two secondary positioning sleeves are symmetrically distributed on the left and right sides with the four-leaf clover pattern folding cup lid as the center.

[0008] Through the above technical solution, the positioning sleeves are symmetrically distributed on the left and right sides with the four-leaf clover pattern folding cup lid as the center, and with the same symmetrically arranged secondary positioning pins, a balanced support is formed.

[0009] As a further improvement to the above solution, the positioning frame is inserted into the inside of the four-leaf clover pattern frame, and the surface of the positioning frame is in contact with the surface of the four-leaf clover pattern folding cup lid.

[0010] Through the above technical solution, the folding connecting plate serves as the central hub, connecting the front cup lid and the rear four-leaf clover patterned lid into one unit, dispersing the pressure to the entire structure. This not only improves the resistance to deformation but also ensures that the stress is evenly distributed across all connection nodes, extending the service life.

[0011] As a further improvement to the above solution, the secondary positioning pin is inserted into the interior of the secondary positioning sleeve, the primary positioning pin is inserted into the interior of the primary positioning sleeve, and the primary positioning pin is inserted into the interior of the four-leaf clover pattern folding cup lid.

[0012] Through the above technical solution, the positioning frame is inserted into the inside of the four-leaf clover pattern frame and contacts the surface of the cup lid, forming an annular sealing surface to prevent liquid from overflowing. The design of the main positioning pin penetrating the cup lid body, combined with the inner wall of the main positioning sleeve, further enhances the sealing effect.

[0013] As a further improvement to the above solution, the secondary positioning pin is inserted into the inside of the four-leaf clover pattern folding cup lid, the folding cover plate is inserted into the inside of the positioning slot, and the folding cover plate is inserted into the top of the four-leaf clover pattern folding cup lid.

[0014] As a further improvement to the above solution, the four-leaf clover patterned cover is located at the rear end of the four-leaf clover patterned folding cup cover, and the number of the secondary positioning pins is set to two, with the two secondary positioning pins symmetrically distributed on the left and right sides with the four-leaf clover patterned cover as the center.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention features a first-level precision fit between the main positioning sleeve and the main positioning pin inside the clover-patterned folding cup lid, and a second-level auxiliary positioning between the secondary positioning sleeve and the secondary positioning pin. The two work together to ensure the positional accuracy of the cup lid in both folded and unfolded states. By setting a positioning slot and the insertion design of the folding cover plate, displacement is restricted through physical interlocking, preventing loosening due to vibration. The dual positioning mechanism makes the opening and closing process of the cup lid smooth and securely locked, effectively preventing liquid spillage and increasing the sealing performance after the overall equipment is installed.

[0016] This invention uses a stepped arrangement of the main and auxiliary positioning pins on the top of the four-leaf clover patterned lid to guide the user to complete the folding action in sequence. By setting the hinge structure of the folding connecting plate in conjunction with the guiding effect of the positioning frame, the opening and closing process of the lid has a damping feel, so that it will not be difficult to open due to excessive resistance, thus improving the convenience of one-handed operation.
