Description

Technical Field

[0001] The present invention relates to the technical field of folding boxes, in particular to a novel folding trolley box. Background Art

[0002] Storage boxes are relatively common in daily life and are mostly used for storing things. Some storage boxes have a pull rod structure, which is convenient for carrying items during daily travel. In addition, in order to facilitate the storage of storage boxes when they are not in use, many storage boxes also adopt a folding design, forming a foldable pull rod box design. For example, the sliding flip cover structure and folding storage box with application number 202020648352.9, the folding scheme of its design is that the left and right side panels are respectively foldable folding panels that intersect in the middle. In the folded state, the folding panels on the left and right sides fold inward, which can effectively reduce the volume. However, this structural scheme needs to be fixed by a locking structure after the folding panel is unfolded, so that the folding panel cannot bend inward again to ensure the stability of the box structure. The lock used in this technical solution is a slider structure slidably set on the plate body. Every time the folding panel needs to be locked or unlocked, it is necessary to slide the lock again, which makes the unfolding or folding operation of the folding box not smooth enough and the operation is relatively anti-locking. Summary of the Invention

[0003] The foldable luggage case is constructed of a plurality of components and has a plurality of side panels, each of which is adapted to be folded and mounted on a plurality of opposite sides of the luggage case. The foldable luggage case is constructed of a plurality of components and is mounted on a plurality of opposite sides of the luggage case. The foldable luggage case is constructed of a plurality of components and is mounted on a plurality of opposite sides of the luggage case. The locking block is mounted on a front surface of the locking block, and the locking block is mounted on a front surface of the locking block, and the front surface of the locking block is rotated and engaged with the first torsion spring, and the second torsion spring is rotated and engaged with the second torsion spring, and the locking block assembly is located in the groove of the inner surface of the first side plate, and the toggle block assembly is higher than the groove of the inner surface of the first side plate. When the bottom plate is folded or unfolded, the toggle block assembly is pushed, and the toggle block assembly drives the locking block assembly to rotate, so that the locking block can be directly pulled out of the insertion slot to unlock or plug in the lock.

[0004] As a preferred solution of the present invention, the front of the locking block is fixedly connected to the limiting boss on the side of the toggle block, and the protruding part on the side of the locking block is a plug connector, which is plugged into the plug slot to achieve the purpose of connecting the first side panel and the second side panel into one and making them unable to be folded. The top of the locking block is fixedly connected to a snap plate, which cooperates with the snap boss.

[0005] As a preferred embodiment of the present invention, the upper end of the toggle block is fixedly connected to a limit plate, the lower portion of the toggle block is adjacent to the limit boss on one side as a first pressing surface, and the other side opposite to the first pressing surface is a second pressing surface. When the bottom plate is flipped up from the bottom, it presses against the second pressing surface, and the toggle block presses against the limit boss, synchronously driving the locking block to rotate, so that the plug connector is pulled out of the plug slot. The snap plate and the snap boss snap together, so that the locking block snaps and stops on the snap boss, achieving separation of the locking block from the second side plate, thereby allowing the first side plate and the second side plate to fold. When the bottom plate is unfolded from the folded state, it presses against the first pressing surface, driving the locking block to rotate, so that the plug connector is inserted into the plug slot, and the first side plate and the second side plate are locked and connected. The rotation of the toggle block can smoothly lower the bottom plate without blocking the bottom plate, and the toggle block is reset under the action of the second torsion spring, so that the bottom plate can press against the second pressing surface when it is folded next time.

[0006] The beneficial effects of the present invention are as follows: the present invention optimizes and improves the locking connection structure of the foldable side panel. Through the cooperation of the locking block assembly and the toggle block assembly, the toggle block assembly is pushed during the folding and unfolding of the bottom plate, and the locking block assembly is driven in linkage, thereby realizing the plug-in fixation and disengagement and unlocking of the second side panel by the locking block; the entire locking connection structure is exquisitely designed, and the linkage design realizes the rapid unfolding or folding of the foldable box without the need for separate locking or unlocking operations. It is easy to use and effectively improves the product experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The locking block assembly 7 is rotatably mounted on the inner side of the first side plate 3 near the second side plate 4. The locking block assembly 7 includes a first rotating shaft 701 fixedly connected to the inner side of the first side plate 3. A locking block 703 is rotatably mounted on the first rotating shaft 701 through a first torsion spring 702. The locking block 703 can maintain a locked state under the action of the first torsion spring 702. The front side of the locking block 703 is fixedly connected to a limited position boss 7031 on the side of the toggle block 803. The protruding part on the side of the locking block 703 is a plug connector 7032, which is correspondingly plugged into the plug slot 401 to achieve The purpose of connecting the first side panel 3 and the second side panel 4 into one body and making it unable to fold is that the top of the locking block 703 is fixedly connected to the snap plate 7033, and the front of the locking block 703 is rotated and fitted with a toggle block assembly 8, and the toggle block assembly 8 includes a second rotating shaft 801 fixedly connected to the locking block 703, and a toggle block 803 is rotated and fitted on the second rotating shaft 801 through a second torsion spring 802. Under the action of the second torsion spring 802, the toggle block 803 can automatically return to its original position after being rotated by an external force, and the upper end of the toggle block 803 is fixedly connected to the limiting plate 8031, and the lower end of the toggle block 803 The side surface close to the limiting boss 7031 is a first pressing surface 8032, and the other side surface opposite to the first pressing surface 8032 is a second pressing surface 8033.
