When not in use, the shelf can be folded up to save storage space. However, its structure is too complicated and the folding operation process is also cumbersome, which affects the use effect of the folding shelf. It is necessary to improve it. Summary of the Invention

[0004] The purpose of this utility model is to address the above-mentioned problems by providing a new type of folding storage rack that is simple in structure and easy to store.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A novel folding storage rack without assembly includes an outer frame, within which a tray frame is disposed. A movable frame is disposed between the outer frame and the tray frame, and the movable frame is engaged with the tray frame. The tray frame has symmetrically arranged mounting shafts on both sides, which are connected to pins on the inner wall of the outer frame. The movable frame is disposed between the outer frame and the tray frame and can slide longitudinally relative to the tray frame. The side wall of the movable frame has elongated sliding holes to avoid the mounting shafts. Movable engaging components are symmetrically arranged on the inner walls of both sides of the movable frame. Corresponding fixed engaging components are symmetrically arranged on both sides of the tray frame. The fixed engaging components are engaged with the movable engaging components, and the engagement between the fixed engaging components and the movable engaging components can be released by the longitudinal sliding motion of the movable frame.

[0006] Furthermore, both the outer frame and the movable frame are inverted U-shaped, with the movable frame fitted inside the outer frame and able to slide longitudinally relative to the outer frame.

[0007] Furthermore, the movable locking component is located below the sliding elongated hole, and the fixed locking component is located at the bottom end of the tray frame. The movable locking component has a locking groove above it for engaging with the fixed locking component. When the bottom end of the movable frame is flush with the bottom end of the outer frame, the fixed locking component is embedded in the locking groove. When the bottom end of the movable frame protrudes from the bottom end of the outer frame, the fixed locking component disengages from the locking groove.

[0008] Furthermore, the fixed locking component has a rectangular block structure, and the movable locking component has a U-shaped configuration with an opening at the top.

[0009] Furthermore, there are several pallet frames, and these pallet frames are arranged at equal intervals along the longitudinal direction; both sides of the several pallet frames are connected to the outer frame pins through mounting shafts, and the bottom ends of both sides of the several pallet frames are provided with fixing fasteners; the movable frame is provided with several sliding elongated holes corresponding to the mounting shafts and several movable fasteners corresponding to the fixing fasteners.

[0010] Furthermore, the bottom end of the lowest pallet frame is provided with a support boss; when the lowest pallet frame is in a horizontal state, the bottom end face of the support boss is flush with the bottom end face of the outer frame.

[0011] Furthermore, the tray frame is arranged in a circular shape, and a storage tray is placed on the upper end of the tray frame.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are: When using this invention, simply rotate the tray frame to a horizontal position, then hold the outer frame and the top of the movable frame with one hand, causing the movable frame to slide upwards. After the movable frame moves upwards, the movable latch on the movable frame engages with the fixed latch on the tray frame, and the tray frame stops rotating. At the same time, the bottom of the movable frame remains flush with the bottom of the outer frame, and placing both directly on the ground completes the unfolding operation of the entire shelf. When the shelf needs to be folded, simply lift the outer frame upwards, and the movable frame will slide downwards relative to the outer frame, disengaging the movable latch from the fixed latch. Then, rotate the tray frame to a vertical position to complete the folding operation of the entire shelf. This shelf has a simple structure, and its unfolding and folding process is more concise, facilitating quick unfolding and folding operations and further improving the usability of the folding shelf.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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, any modifications, equivalent substitutions, improvements, etc., made by those skilled in the art to all other embodiments obtained without creative effort should be included within the protection scope of the present utility model.

[0016] like Figures 1 to 4 As shown, this embodiment discloses a novel folding storage rack that does not require assembly, including an outer frame 1, a tray rack 3 disposed inside the outer frame 1, and a movable frame 2 disposed between the outer frame 1 and the tray rack 3, the movable frame 2 being engaged with the tray rack 3. There are two tray frames 3, which are arranged sequentially along the longitudinal direction; the tray frames 3 are arranged in a circular shape, and a storage tray 4 is placed on the upper end of the tray frame 3; the two sides of the tray frame 3 are symmetrically arranged with mounting shafts 301, which are connected to the inner wall pins of the outer frame 1 through the mounting shafts 301.

[0017] The structure of the pallet frame and the outer frame connected by pins means that the supporting force is on the mounting shaft and the outer frame, and the movable frame does not need to bear the force, so that the weight placed on the pallet frame will not affect the fixation effect of the movable frame; at the same time, the movable frame and the outer frame fit together inside and out, making the outer frame structure more robust.

[0018] The bottom of the tray frame 3 is provided with a support boss 303; when the bottom of the tray frame 3 is in a horizontal state, the bottom end face of the support boss 303 is flush with the bottom end face of the outer frame 1, so that the entire shelf can be placed stably on the ground.

[0019] The outer frame 1 and the movable frame 2 are both inverted U-shaped. The movable frame 2 is located between the outer frame 1 and the pallet frame 3 and can slide longitudinally relative to the pallet frame 3 and the outer frame 1. The side wall of the movable frame 2 is provided with a sliding elongated hole 201 for avoiding the mounting shaft 301. Movable locking parts 202 are symmetrically arranged on the inner walls of both sides of the movable frame 2. The movable locking parts 202 are located below the sliding elongated hole 201 and are U-shaped with an open top so that their tops form locking grooves. The bottom ends of both sides of the pallet frame 3 are symmetrically provided with fixed locking parts 302 corresponding to the movable locking parts 202. The fixed locking parts 302 are rectangular blocks. The fixed locking parts 302 are engaged with the movable locking parts 202 and the engagement between the fixed locking parts 302 and the movable locking parts 202 can be released by the longitudinal sliding action of the movable frame 2.

[0020] When the bottom end of the movable frame 2 is flush with the bottom end of the outer frame 1, the fixed locking piece 302 is inserted into the locking groove at the top of the movable locking piece 202, and the pallet frame 3 cannot rotate; when the bottom end of the movable frame 2 protrudes from the bottom end of the outer frame 1, the fixed locking piece 302 disengages from the locking groove at the top of the movable locking piece 202, and the pallet frame 3 can rotate and fold.

[0021] This technical solution differs from traditional shelves that require three or more legs for mutual support on the ground. This solution only requires placing the two legs of the outer frame on the ground, with the support boss of the bottom tray providing additional support to achieve stable placement. Its unfolded state is as sturdy as traditional welding, offering excellent stability. Furthermore, this design allows for a narrower outer frame. When folded, the tray can rotate and overlap with the outer frame, minimizing the storage space occupied and enabling flat storage for greater convenience.

[0022] When using this invention, simply rotate the tray frame to a horizontal position, then hold the outer frame and the top of the movable frame with one hand, causing the movable frame to slide upwards. After the movable frame moves upwards, the movable latch on the movable frame engages with the fixed latch on the tray frame, and the tray frame stops rotating. At the same time, the bottom of the movable frame remains flush with the bottom of the outer frame, and placing both directly on the ground completes the unfolding operation of the entire shelf. When the shelf needs to be folded, simply lift the outer frame upwards, and the movable frame will slide downwards relative to the outer frame, disengaging the movable latch from the fixed latch. Then, rotate the tray frame to a vertical position to complete the folding operation of the entire shelf. This shelf has a simple structure, and its unfolding and folding process is more concise, facilitating quick unfolding and folding operations and further improving the usability of the folding shelf.
