[0002] As people's demand for outdoor life continues to increase, their dependence on storage boxes is also increasing. Storage boxes are usually composed of an upper cover and a lower box body that snap together to form a storage chamber. Therefore, when opening the storage chamber, users usually need to manually flip the upper cover to open the storage box and take out items.

[0003] When a user uses a storage box, the cover of existing storage boxes on the market is connected to the lower box body by a flip opening and closing mechanism. The existing flip opening and closing mechanism is generally equipped with a damper to limit the flip mechanism's operation. However, after long-term use of the upper cover, the damping effect inside the flip opening and closing mechanism will deteriorate. As a result, the user needs to manually support the upper cover when opening the storage box to prevent the flip opening and closing mechanism from moving under the upper cover's own weight, which poses a safety hazard. Therefore, it is necessary to propose a flip opening and closing mechanism with a limiter component to solve the above problem. Utility Model Content

[0028] This utility works as follows:

[0029] Refer to the instruction manual Figure 1-4 , hold the pull ring 301 and press the movable block 302, so that the movable block 302 drives the fixed plate 304 to squeeze the return spring 305 through the connecting column 303, and the fixed plate 304 squeezes the return spring 305 to shrink and move, releasing the squeeze on the sliding plate 306, so that the sliding plate 306 releases the squeeze on the contraction spring 307, and the contraction spring 307 pushes the sliding plate 306 to move, and the movement of the sliding plate 306 drives the fixed column 308 to move, so that the fixed column 308 shrinks from the inside of the support column 203 back to the inside of the flip cover 201, releasing the position fixation of the support column 203, and then pull the pull ring 301, so that the pull ring 301 drives the flip cover 201 to be fixed in the box body 1 through the connecting shaft 202. The top flips open, and at the same time, the support column 203 slides on both sides of the flip cover 201, and the torsion spring 205 that squeezes the outer wall of the rotating shaft 204 rotates, causing the bottom end of the support column 203 to rotate and extend to support the flip cover 201 in the open state. Then, the squeezing of the movable block 302 is released, so that the return spring 305 pushes the fixed plate 304 to reset. The fixed plate 304 resets and squeezes the sliding plate 306, so that the sliding plate 306 squeezes the contraction spring 307 to shrink and move.
