Description

Technical Field

[0001] This invention relates to the technical field of the outer frame structure of ton barrels and ton bags, and more particularly to a foldable support frame structure. Background Technology

[0002] In the transportation of powders, liquids, and granular materials, ton drums and ton bags are common transport and storage packaging containers. However, the outer frame of traditional ton drums and ton bags is a single structure, which makes storage and transportation extremely inconvenient after the contents of the ton drum or ton bag are used up, resulting in increased storage and transportation costs. To solve the above problems, this invention proposes a foldable support frame structure. Summary of the Invention

[0003] To address the aforementioned problems, this invention proposes a foldable support frame structure, aiming to solve the issues of large space occupation and high transportation costs associated with traditional ton barrel and ton bag frames.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A foldable support frame structure, serving as the outer frame for a ton container or ton bag, includes a base. Three edges of the base top, arranged in a clockwise or counter-clockwise direction, have progressively increasing height blocks. The edges of the base top without these blocks, and each block, are hinged to a side panel that can be flipped towards the top end face of the base. The tops of all side panels are at the same horizontal height. Adjacent top sections of two adjacent side panels are detachably fitted with locking buckles to form the outer frame. When the side panel is folded towards the top end face of the base, it falls within the base's coverage area.

[0005] Preferably, the locking buckle includes a right-angle base, and the right-angle base has a limiting groove at the top edge of the corresponding side plate, and the limiting groove is detachably locked onto the top of the side plate.

[0006] Preferably, the right-angle base is also provided with a threaded hole that passes through the limiting groove.

[0007] Preferably, a reinforcing plate is fixed between the two inner corners of the right-angle base.

[0008] Preferably, each side of the outer frame is provided with multiple spaced limiting mechanisms, each limiting mechanism including a limiting plate, which is mounted on the side of the base via a rotating shaft.

[0009] Preferably, the limiting mechanism further includes a hook pin, which is screwed onto the side plate, and the limiting plate is provided with a hook that can be attached to the hook pin, and the hook pin has an anti-detachment protrusion.

[0010] Preferably, one of the side plates has a discharge port.

[0011] Compared with the prior art, the present invention has the following beneficial effects: The outer frame structure disclosed in this invention is simple and can be quickly folded after use to reduce space occupation, thereby facilitating transportation and storage and reducing transportation and storage costs. At the same time, it has high compressive strength when unfolded. Attached Figure Description

[0014] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0015] Example 1 This embodiment discloses a foldable support frame structure, which serves as the outer frame of a ton container or ton bag. After the contents of the ton container or ton bag are used up, the outer frame can be quickly folded to reduce space occupation, thereby facilitating transportation and storage and indirectly reducing transportation and storage costs.

[0016] The above-mentioned foldable support frame structure is as follows Figure 1-2As shown, the device includes a base 1. Three of the top edges of the base 1, arranged in a clockwise or counter-clockwise direction, have increasing height blocks 2. The edges of the base 1 without increasing blocks 2 are also present. Each increasing block 2 has a side plate 4 that can be flipped towards the top end face of the base 1 via a hinge 3. The height of the side plates 4 is adjusted using the increasing blocks 2 to ensure they can be flipped towards the top end face of the base 1, and the tops of multiple side plates 4 are all at the same horizontal height. Adjacent tops of two adjacent side plates 4 are detachably equipped with locking buckles 5 to form an outer frame for placing ton containers or ton bags. When the contents of the ton containers or ton bags are used up, the locking buckles 5 are removed from the outer frame. At this time, the multiple side plates 4, in decreasing order of length, are flipped towards the top end face of the base 1 to fold the outer frame, thereby reducing the space occupied by the outer frame and facilitating transportation and storage. Preferably, when the side panel 4 is folded along the direction close to the top end face of the base 1, the side panel 4 is within the coverage area of ​​the base 1, which indirectly limits the length of the side panel 4 and avoids the situation where the side panels 4 interfere with each other when the outer frame is folded due to the excessive length of the side panel 4.

[0017] As a preferred embodiment of the above embodiments, the locking buckle 5 has the following structure: Figure 2 As shown, the frame includes a right-angle base 51, with a limiting groove 52 formed on the top edge of the corresponding side plate 4. The limiting groove 52 is detachably engaged with the top of the side plate 4. Specifically, when all the side plates 4 of the outer frame are in a vertical position, a right angle is formed between two adjacent side plates 4, and the limiting groove 52 on the right-angle base 51 is engaged with the top angle region of the two adjacent side plates 4, thereby locking the position of each side plate 4.

[0018] As a preferred embodiment of the above, the right-angle base 51 is also provided with a screw hole that passes through the limiting groove 52. After the limiting groove 52 is engaged on the top of the side plate 4, a screw that matches the screw hole is passed through the screw hole and screwed into the side plate 4, thereby making the connection between the right-angle base 51 and the side plate 4 stable.

[0019] As a preferred embodiment of the above, a reinforcing plate 53 is fixed between the two inner corner sides of the right-angle base 51, which makes the structural angle of the right-angle base 51 higher, improves the load-bearing capacity of the two right-angle sides of the right-angle base 51, and reduces the risk of deformation of the two right-angle sides under stress.

[0020] As a preferred embodiment of the above, each side of the outer frame is provided with a plurality of spaced-apart limiting mechanisms 6. Each limiting mechanism 6 includes a limiting plate 61, which is mounted to the side of the base 1 via a rotating shaft 62. Specifically, when the limiting plate 61 is rotated and abuts against the side plate 4, it blocks the movement trajectory of the bottom of the outer side wall when the side plate 4 is flipped, preventing the side plate 4 from flipping towards the top end face of the base 1, thus making the structure of the formed outer frame more stable. When the outer frame needs to be folded, simply rotate the limiting plate 61 away from the side plate 4.

[0021] As a preferred embodiment of the above, the limiting mechanism 6 further includes a hook pin 63, which is screwed onto the side plate 4. The limiting plate 61 is provided with a hook 64 that can be hooked onto the hook pin 63. The hook pin 63 has an anti-detachment protrusion. After the limiting plate 61 abuts against the side plate 4, the hook 64 on the limiting plate 61 abuts against the hook pin 63 and is located between the anti-detachment protrusion and the side plate 4. In this embodiment, the hook 64 and the hook pin 63 cooperate with each other to prevent the limiting plate 61 from rotating away from the side plate 4 during transportation or storage, and the anti-detachment protrusion is used to prevent the hook 64 from detaching from the hook pin 63 during transportation or storage.

[0022] As a preferred embodiment of the above, one of the side plates 4 is provided with a discharge port.

[0023] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and modifications according to the present invention, but these corresponding changes and modifications should all fall within the protection scope of the appended claims.
