Abstract
Description
[Technical Field]
[0001] The present application relates to the field of folding structures, and more particularly to folding structures and storage shelves to which the folding structures are applied. [Background technology]
[0002] Folding structures are widely used in daily life, and their core concept is to reduce the volume of an item when it is not in use through a folding structure through an intricate geometric structure design, thereby facilitating storage of the item. Folding structures can be applied to structures such as folding bookshelves, folding storage shelves, and folding stairs.
[0003] A conventional folding structure generally includes a folding bar, which includes two folding sections, which are hingedly connected to each other, and both ends of the folding bar are rotatably connected to both sides of the object to be folded. When it is necessary to fold both sides of the object to be folded toward each other, the two folding sections rotate toward each other, thereby allowing the both sides of the object to move toward each other, thereby achieving the folding of both sides of the object to be folded.
[0004] Compared to the above-mentioned related art, the conventional folding structure has poor stability in the unfolded or folded state, and when subjected to an external force, it is easy to switch from the unfolded state to the folded state or from the folded state to the unfolded state. Summary of the Invention [Problem to be solved by the invention]
[0005] In order to improve the stability of the folding structure, the present application provides a folding structure and a storage shelf that applies the folding structure. [Means for solving the problem]
[0006] The folding structure and the storage shelf using the folding structure according to the present application adopt the following technical solutions.
[0007] A folding structure, comprising a horizontal folding bar and at least two inclined folding bars, the horizontal folding bar including two horizontal folding sections, the two horizontal folding sections being hingedly connected to each other to form a horizontal folding bar, and both ends of the horizontal folding bar being rotatably connected to both sides of an object to be folded, respectively; One end of each of the inclined folding bars is rotatably connected to the horizontal folding bar, the other end of each of the inclined folding bars is rotatably connected to both sides of the folding object, each of the inclined folding bars is symmetrically distributed along the hinge connection point of the horizontal folding bar, each of the inclined folding bars includes two inclined folding sections, and the two inclined folding sections are hingedly connected to each other to form an inclined folding bar.
[0008] By adopting the above technical solution, when folding the folding structure, the horizontal folding bar is folded by rotating the two horizontal folding sections of the horizontal folding bar toward each other, and the two oblique folding sections of each oblique folding bar are rotated toward each other to complete the folding of each oblique folding bar itself. Furthermore, by rotating each oblique folding bar further toward the horizontal folding section, the folding between the horizontal folding bar and each oblique folding bar is achieved. When the folding structure is unfolded, each oblique folding bar forms a triangular structure with the horizontal folding bar, and each oblique folding bar is stacked along the hinge connection point of the horizontal folding bar, which improves the stability of the folding structure when unfolded and solves the problem of conventional folding structures having poor stability in the unfolded or folded state and being unable to easily switch from the unfolded state to the folded state or from the folded state to the unfolded state when subjected to external force.
[0009] Optionally, the rotation points at which each of the angled folding bars connect to the horizontal folding bar all coincide with hinge connection points of the horizontal folding bar.
[0010] Optionally, the folding direction of each of the diagonal folding bars is the same as the folding direction of the horizontal folding bar.
[0011] Optionally, a horizontal limit groove is opened in one of the horizontal folding sections, and a horizontal limit block is fixedly provided in the other inclined folding section, and when the two horizontal folding sections are hinged to each other, the horizontal limit block penetrates and slidably fits into the horizontal limit groove.
[0012] Optionally, a tilt limit groove is opened in one of the tilt folding sections, and a tilt limit block is fixedly provided in the other of the tilt folding sections, and when the two tilt folding sections are hinged to each other, the tilt limit block penetrates and slidably fits into the tilt limit groove.
[0013] A storage shelf comprising two support frames and a folding structure arranged between the two support frames, the folding structure being arranged between the two support frames, with both ends of the horizontal folding bar being rotatably connected to the two support frames respectively, and one end of each of the inclined folding bars being rotatably connected to the two support frames respectively.
[0014] Optionally, at least one storage plate is further provided between the two support frames, and both ends of each storage plate are removably connected to the two support frames, respectively.
[0015] Optionally, at least one storage cabinet is further provided between the two support frames, and a sliding rod is fixedly connected to both sides of each storage cabinet, and a plurality of sliding guide rails are fixedly provided on each of the two support frames, and when each storage cabinet is provided between the two support frames, each sliding rod passes through and is slidably fitted into each of the sliding guide rails. [Effects of the Invention]
[0016] As described above, the present application has at least one of the following beneficial technical effects.
[0017] When the folding structure is folded, the horizontal folding bar is folded by rotating the two horizontal folding sections of the horizontal folding bar toward each other, and the two oblique folding sections of each oblique folding bar are rotated toward each other to complete the folding of each oblique folding bar itself. Furthermore, by rotating each oblique folding bar further toward its horizontal folding section, the folding between the horizontal folding bar and each oblique folding bar is achieved. When the folding structure is unfolded, each oblique folding bar forms a triangular structure with the horizontal folding bar, and each oblique folding bar is stacked along the hinge connection point of the horizontal folding bar. This improves the stability of the folding structure when unfolded, and solves the problem of conventional folding structures having poor stability in the unfolded or folded state and being unable to easily switch from the unfolded state to the folded state or from the folded state to the unfolded state when subjected to external force.

[0019] The present invention will be described in more detail below with reference to FIGS.
[0020] The embodiment of the present application discloses a folding structure and a storage shelf to which the folding structure is applied. Referring to Fig. 1, the folding structure includes a horizontal folding bar 1 and two inclined folding bars 2.
[0021] 1 to 4, the horizontal folding bar 1 includes two horizontal folding sections 11, one end of which is hinged to each other to form the horizontal folding bar 1. In the embodiment of the present application, the position where the two horizontal folding sections 11 are hinged to each other is the hinge connection point of the horizontal folding bar 1. A horizontal limit groove 111 is formed through one of the horizontal folding sections 11, and the groove body of the horizontal limit groove 111 is semicircular. A horizontal limit block is fixedly provided on the other horizontal folding section 11, and the two horizontal folding sections 11 are hinged to each other. In this case, the horizontal limit block penetrates and slidably fits into the horizontal limit groove 111, so that when the horizontal folding bar 1 is unfolded, the maximum unfolding angle of the horizontal folding bar 1 is 180°, and the minimum unfolding angle of the horizontal folding bar 1 is 0°. The unfolding angle of the horizontal folding bar 1 is the angle between the two horizontal folding sections 11. In the embodiment of the present application, the foldable direction of the horizontal folding bar 1 is the folding direction of the horizontal folding bar 1. When the folding structure is installed and used, both ends of the horizontal folding bar 1 are rotatably connected to both sides of the object to be folded.
[0022] Referring to Figures 1 to 4, one end of each of the two inclined folding bars 2 is rotatably connected to the horizontal folding bar 1, and the other ends of the two inclined folding bars 2 are rotatably connected to both sides of the object to be folded, respectively. The two inclined folding bars 2 are symmetrically distributed along the hinge connection point of the horizontal folding bar 1, and in the embodiments of the present application, the rotation points at which each inclined folding bar 2 is connected to the horizontal folding bar 1 all coincide with the hinge connection point of the horizontal folding bar 1, thereby further improving the stability of the folding structure when unfolded.
[0023] 1 to 4, each of the two oblique folding bars 2 includes two oblique folding sections 21, which are hinged to each other to form the oblique folding bar 2. In the embodiment of the present application, the position where the two oblique folding sections 21 are hinged to each other is the hinge connection point of the oblique folding bar 2. One of the oblique folding sections 21 has an oblique limit groove formed therethrough, and the groove body of the oblique limit groove is semicircular. The other oblique folding section 21 has an oblique limit block fixed thereto. When the two oblique folding sections 21 are hinged to each other, the oblique limit block penetrates the oblique limit groove and slidably fits into it. Therefore, when the oblique folding bar 2 is unfolded, the maximum unfolding angle of the oblique folding bar 2 is 180°. , the minimum unfolding angle of the inclined folding bar 2 is 0°, and the unfolding angle of the inclined folding bar 2 is the included angle between the two inclined folding sections 21. In the embodiment of the present application, the foldable direction of the inclined folding bar 2 is the folding direction of the inclined folding bar 2, and the folding direction of each inclined folding bar 2 is the same as the folding direction of the horizontal folding bar 1, i.e., folding up simultaneously or folding down simultaneously. When the folding structure is installed and used, the two distant ends of the two inclined folding bars 2 are respectively rotatably connected to both sides of the folding object. When the folding structure is fully unfolded, any of the inclined folding bars 2, the horizontal folding bar 1 and one side of the folding object form a triangle, which may be a right-angled triangle, an obtuse-angled triangle, or an acute-angled triangle.
[0024] The implementation principle of the folding structure according to the embodiment of the present application: when folding the folding structure, the horizontal folding bar 1 is folded by rotating the two horizontal folding sections 11 of the horizontal folding bar 1 in a direction to approach each other, and the two inclined folding sections 21 of each inclined folding bar 2 are rotated in a direction to approach each other, respectively, to complete the folding of each inclined folding bar 2 itself, and by rotating each inclined folding bar 2 in a direction to approach the horizontal folding section 11, the horizontal folding bar 1 and each inclined folding section 21 are connected. When the folding structure is unfolded, each inclined folding bar 2 forms a triangular structure with the horizontal folding bar 1, and each inclined folding bar 2 is stacked along the hinge connection point of the horizontal folding bar 1, which improves the stability of the folding structure when unfolded and improves the problem of conventional folding structures having poor stability in the unfolded or folded state and being unable to easily switch from the unfolded state to the folded state or vice versa when subjected to external force.
[0025] 5 to 9, the storage shelf includes two support frames 20 and a folding structure 10 disposed between the two support frames 20, with both ends of a horizontal folding bar 1 rotatably connected to the two support frames 20, one end of each inclined folding bar 2 rotatably connected to the two support frames 20, two storage plates 201 disposed between the two support frames 20, both ends of each storage plate 201 removably connected to the two support frames 20, and two storage cabinets 202 disposed between the two support frames 20, with each storage cabinet A sliding rod 2021 is fixedly connected to both sides of the net 202, and a plurality of sliding guide rails 2022 are fixedly mounted on each of the two support frames 20. When each storage cabinet 202 is mounted between the two support frames 20, each sliding rod 2021 passes through and slidably fits into each sliding guide rail 2022, and each sliding rod 2021 can be detached from the connection between each sliding guide rail 2022. Universal wheels 203 are fixedly connected to the bottom of the two support frames 20, making it easy to move the storage cabinet.
