[0047] In order to make the technical problems, technical solutions and beneficial effects to be solved by the utility model clearer, the utility model is further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

In addition, it should be noted that this specification describes many features. Although certain features can be combined together to illustrate possible system designs, these features can also be used in other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0048] The principle and structure of the present utility model are described in detail below with reference to the accompanying drawings and embodiments.

[0049] Example 1

[0050] In the prior art, in order to enable a multi-layer storage rack to be used firmly, generally, a "C"-shaped protective frame is additionally added to the vertical rod between adjacent two-layer storage wire frames to increase the firmness and stability of the multi-layer storage rack. However, the existing protective frame is not foldable, resulting in a large packaging volume of the protective frame, inconvenient transportation, and relatively high transportation costs.

[0051] Therefore, in order to solve the above problems, referring to the attached Figure 1 , the present utility model proposes a foldable protective frame, which includes a fixed rod 1 and movable rods 2 respectively arranged at both ends of the fixed rod 1. One end of each movable rod 2 and on the side facing the other movable rod 2 is provided with a first rotating member 21; on the other side of one end of each movable rod 2 and away from the first rotating member 21 is provided with a first limiting member 22.

[0052] Corresponding to the first rotating member 21, a second rotating member 11 is hinged to each end of the fixed rod 1, and corresponding to the first limiting member 22, a second limiting member 12 is detachably connected to each end of the fixed rod 1.

[0053] Wherein, when the first limiting member 22 and the second limiting member 12 are disassembled, the protective frame can be in a folded state; when the first limiting member 22 and the second limiting member 12 are installed, the protective frame can be in an open state.

[0054] In this way, when it is necessary to package and transport the protective frame, the first limiting member 22 of each movable rod 2 can be disassembled from the second limiting member 12 of the fixed rod 1, and then each first rotating member 21 of each movable rod 2 can be rotated relative to the second rotating member 11 of the fixed rod 1 so that each movable rod 2 is closely attached to the fixed rod 1 to complete folding, reducing the volume of the protective frame, and further reducing the packaging volume of the protective frame, facilitating transportation, and reducing transportation costs.

[0055] Among them, for a clear understanding of the hinge between the first rotating member 21 and the second rotating member 11, referring to the attached Figure 1 , this embodiment proposes a hinge structure between the first rotating member 21 and the second rotating member 11, specifically:

[0056] One end of each movable rod 2 and on the upper part of the side facing the other movable rod 2 is provided with a first rotating member 21; corresponding to the first rotating member 21, a second rotating member 11 is provided at the lower part of each end of the fixed rod 1.

[0057] The first rotating member 21 is vertically provided with a first rotating through hole 211 and a rotating shaft 212 penetrating itself, and the second rotating member 11 is vertically provided with a second rotating through hole 111 penetrating itself; the movable rod 2 is also provided with a rotating shaft 212 corresponding to the first rotating through hole 211 and the second rotating through hole 111.

[0058] The first rotating member 21 and the second rotating member 11 are placed overlapping each other, and the center lines of the first rotating through hole 211 and the second rotating through hole 111 are both on the same vertical line.

[0059] When the rotating shaft 212 is matched and inserted into the first rotating through hole 211 and the second rotating through hole 111 , the first rotating through hole 211 and the second rotating through hole 111 can rotate relative to each other around the rotating shaft 212 to form a hinge.

[0060] It should be noted that the rotating shaft 212 in this embodiment is preferably a latch, so that when packaging the protective frame, the rotating shaft 212 can even be removed from the first rotating through hole 211 and the second rotating through hole 111 to separate the movable rod 2 and the fixed rod 1, thereby reducing the volume of the protective frame and further reducing the packaging volume of the protective frame for easy transportation and reducing transportation costs.

[0061] The first rotating through hole 211 and the second rotating through hole 111 are both cylindrical in shape and have the same size. Thus, when the first stopper 22 and the second stopper 12 are in the disassembled state, the movable rod 2 can rotate relative to the fixed rod 1 to complete the opening or folding.

[0062] In order to clearly understand the detachable connection between the first stopper 22 and the second stopper 12, refer to the attached Figure 1 , this embodiment proposes a detachable connection structure between the first limiting member 22 and the second limiting member 12, specifically:

[0063] A first limiting member 22 is provided at one end of each movable rod 2 and at the upper portion of the other side away from the first rotating member 21 ; a second limiting member 12 is provided at the lower portion of each end of the fixed rod 1 corresponding to the first limiting member 22 .

[0064] The first limiting member 22 includes a first limiting through hole 221 and a latch 222 vertically passing through the first limiting member 22, and the second limiting member 12 includes a second limiting through hole 121 vertically passing through the second limiting member 12.

[0065] The first limiting member 22 and the second limiting member 12 are placed overlappingly, and the center lines of the first limiting through hole 221 and the second limiting through hole 121 are both on the same vertical line.

[0066] When the latch 222 is matched and detachably inserted into the first limiting through hole 221 and the second limiting through hole 121 , the fixed rod 1 and the movable rod 2 are connected.

[0067] It should be noted that when the latch 222 is matched and detachably inserted into the first limiting through hole 221 and the second limiting through hole 121 , the first limiting through hole 221 and the second limiting through hole 121 cannot rotate relative to each other around the latch 222 .

[0068] The first limiting through hole 221 and the second limiting through hole 121 are both cylindrical in shape, and the first limiting through hole 221 and the second limiting through hole 121 are of the same size. In this way, when the protective frame needs to be in a fully opened state, refer to the attached Figure 2 , the first rotating member 21 of each movable rod 2 is rotated relative to the second rotating member 11 of the fixed rod 1 to fully open the protective frame. At this time, the first limiting member 22 and the second limiting member 12 are overlapped and placed up and down, and then the latch 222 is inserted into the first limiting through hole 221 and the second limiting through hole 121 in sequence to fix the fixed rod 1 and the movable rod 2 to prevent the movable rod 2 from swinging relative to the fixed rod 1.

[0069] When the protective frame needs to be in a fully folded state, refer to the attached Figure 3 , first pull out the latch 222 from the first limiting through hole 221 and the second limiting through hole 121, and then rotate the first rotating member 21 of each movable rod 2 relative to the second rotating member 11 of the fixed rod 1 to completely fold the protective frame.

[0070] To ensure the firmness and stability of the protection frame, the maximum opening angle of the movable rod 2 relative to the fixed rod 1 is 90°.

[0071] Among them, refer to the attached Figure 2 Both ends of the fixing rod 1 are provided with a first mounting through hole 13 , and the first mounting through hole 13 is correspondingly provided with a second rotating member 11 and a second limiting member 12 .

[0072] A second mounting through hole 23 is formed at one end of each movable rod 2 away from the first rotating member 21 .

[0073] In this way, when the protective frame is in a fully open state, the fixed rod 1 and the movable rod 2 can be enclosed to form a rectangle or a square. At this time, the first mounting hole 13 and the second mounting hole 23 will be respectively located at the four corners of the protective frame. At this time, the support rod of the storage rack will respectively pass through the first mounting hole 13 and the second mounting hole 23 to stably install the protective frame on the storage rack.

[0074] The material of the fixed rod 1 and the movable rod 2 is any one of carbon steel, plastic, stainless steel and aluminum alloy. Of course, the material of the fixed rod 1 and the movable rod 2 can also be other rigid and light suitable materials, which are not limited here.

[0075] In this embodiment, the material of the fixed rod 1 and the movable rod 2 is preferably carbon steel.

[0076] It should be noted that the structures of the fixed rod 1 and the movable rod 2 in this embodiment are preferably hollow structures. In this way, while ensuring the rigidity and strength of the fixed rod 1 and the movable rod 2 themselves, the weight of the fixed rod 1 and the movable rod 2 themselves can be reduced, making them lighter and more in line with people's needs, and can further reduce transportation costs (because the larger the volume and heavier the weight of the object, the higher the transportation cost).

[0077] Example 2

[0078] See attached Figure 4 The utility model proposes another foldable protective frame, including a fixed rod 1 and movable rods 2 respectively arranged at both ends of the fixed rod 1, and a first rotating member 21 is provided at one end of each movable rod 2 and on a side facing the other movable rod 2; a first limiting member 22 is provided at one end of each movable rod 2 and on the other side away from the first rotating member 21.

[0079] Each end of the fixing rod 1 is hingedly connected to the second rotating member 11 corresponding to the first rotating member 21 , and each end of the fixing rod 1 is detachably connected to the second limiting member 12 corresponding to the first limiting member 22 .

[0080] When the first limiting member 22 and the second limiting member 12 are disassembled, the protection frame can be in a folded state; when the first limiting member 22 and the second limiting member 12 are installed, the protection frame can be in an open state.

[0081] In this way, when the protective frame needs to be packaged and transported, the first limit piece 22 of each movable rod 2 can be removed relative to the second limit piece 12 of the fixed rod 1, and then the first rotating piece 21 of each movable rod 2 can be rotated relative to the second rotating piece 11 of the fixed rod 1, so that each movable rod 2 can be pressed against the fixed rod 1 to complete the folding, thereby reducing the volume of the protective frame, and then reducing the packaging volume of the protective frame, so as to facilitate transportation and reduce transportation costs.

[0082] In order to clearly understand the hinge between the first rotating member 21 and the second rotating member 11, refer to the attached Figure 4 This embodiment proposes a hinge structure between the first rotating member 21 and the second rotating member 11, specifically:

[0083] A first rotating member 21 is provided at one end of each movable rod 2 and at the upper portion of a side facing the other movable rod 2 ; a second rotating member 11 is matched and provided at the lower portion of each end of the fixed rod 1 corresponding to the first rotating member 21 .

[0084] The first rotating member 21 is vertically provided with a first rotating through hole 211 and a rotating shaft 212 penetrating the first rotating through hole 211 and the second rotating through hole 111 penetrating the second rotating through hole 111 ; the movable rod 2 is also matched with a rotating shaft 212 corresponding to the first rotating through hole 211 and the second rotating through hole 111 .

[0085] The first rotating member 21 and the second rotating member 11 are placed overlapping each other, and the center lines of the first rotating through hole 211 and the second rotating through hole 111 are both on the same vertical line.

[0086] When the rotating shaft 212 is matched and inserted into the first rotating through hole 211 and the second rotating through hole 111 , the first rotating through hole 211 and the second rotating through hole 111 can rotate relative to each other around the rotating shaft 212 to form a hinge.

[0087] It should be noted that the rotating shaft 212 in this embodiment is preferably a latch, so that when packaging the protective frame, the rotating shaft 212 can even be removed from the first rotating through hole 211 and the second rotating through hole 111 to separate the movable rod 2 and the fixed rod 1, thereby reducing the volume of the protective frame and further reducing the packaging volume of the protective frame for easy transportation and reducing transportation costs.

[0088] The first rotating through hole 211 and the second rotating through hole 111 are both cylindrical in shape and have the same size. Thus, when the first stopper 22 and the second stopper 12 are in the disassembled state, the movable rod 2 can rotate relative to the fixed rod 1 to complete the opening or folding.

[0089] In order to clearly understand the detachable connection between the first stopper 22 and the second stopper 12, refer to the attached Figure 4 This embodiment proposes another detachable connection structure between the first limiting member 22 and the second limiting member 12, specifically:

[0090] A first limiting member 22 is provided at one end of each movable rod 2 and in the middle of the other side away from the first rotating member 21 ; a second limiting member 12 is provided in the middle of each end of the fixed rod 1 corresponding to the first limiting member 22 .

[0091] The first limiting member 22 includes a first limiting sliding groove 223 and a sliding member 224 matched and embedded in the first limiting sliding groove 223 . The second limiting member 12 includes a second limiting sliding groove 122 ; and the sliding member 224 can match and slide into the second limiting sliding groove 122 .

[0092] When the sliding member 224 slides from the first limiting sliding groove 223 into the second limiting sliding groove 122 , the fixed rod 1 and the movable rod 2 are connected.

[0093] In this way, when the protective frame needs to be in a fully open state, refer to the attached Figure 5, the first rotating member 21 of each movable rod 2 is rotated relative to the second rotating member 11 of the fixed rod 1 to fully open the protective frame. At this time, the first limiting member 22 and the second limiting member 12 are overlapped and placed up and down, and then the sliding member 224 is slid from the first limiting slot 223 into the second limiting slot 122 to connect the fixed rod 1 and the movable rod 2 to prevent the movable rod 2 from swinging relative to the fixed rod 1.

[0094] When the protective frame needs to be in a fully folded state, the sliding member 224 is first slid back from the second limiting sliding groove 122 to the first limiting sliding groove 223. Figure 6 Then, the first rotating member 21 of each movable rod 2 is rotated relative to the second rotating member 11 of the fixed rod 1 to completely fold the protection frame.

[0095] It should be noted that, refer to the attached Figure 4 The shape of the sliding member 224 is preferably a rectangular parallelepiped, and in order to facilitate the user to control the sliding member 224 to slide in the first limiting slide groove 223 and the second limiting slide groove 122, the first limiting slide groove 223 and the second limiting slide groove are provided with an opening on the side facing the other movable rod 2, and the sliding member 224 has a handle 2241 extending outwardly from the side facing the opening, and the handle 2241 is located in the opening, so that the user can pinch or hold the handle 2241 with his hand to control the sliding member 224 to slide in the first limiting slide groove 223 and the second limiting slide groove 122.

[0096] In order to ensure that the sliding member 224 does not fall from the first limiting slot 223 when sliding from the second limiting slot 122 back to the first limiting slot 223, refer to the attached Figure 4 A baffle 2231 is provided on one side of the first limiting sliding groove 223 along the sliding direction in which the sliding member 224 slides out of the second limiting sliding groove 122 .

[0097] In order to reduce the volume of the protection frame and further reduce the packaging volume of the protection frame for easy transportation and to reduce transportation costs, the length of the second limiting sliding groove 122 does not exceed the width of the movable rod 2 .

[0098] To ensure the firmness and stability of the protection frame, the maximum opening angle of the movable rod 2 relative to the fixed rod 1 is 90°.

[0099] Among them, refer to the attached Figure 5 Both ends of the fixing rod 1 are provided with a first mounting through hole 13 , and the first mounting through hole 13 is correspondingly provided with a second rotating member 11 and a second limiting member 12 .

[0100] A second mounting through hole 23 is formed at one end of each movable rod 2 away from the first rotating member 21 .

[0101] In this way, when the protective frame is in a fully open state, the fixed rod 1 and the movable rod 2 can be enclosed to form a rectangle or a square. At this time, the first mounting hole 13 and the second mounting hole 23 will be respectively located at the four corners of the protective frame. At this time, the support rod of the storage rack will respectively pass through the first mounting hole 13 and the second mounting hole 23 to stably install the protective frame on the storage rack.

[0102] The material of the fixed rod 1 and the movable rod 2 is any one of carbon steel, plastic, stainless steel and aluminum alloy. Of course, the material of the fixed rod 1 and the movable rod 2 can also be other rigid and light suitable materials, which are not limited here.

[0103] In this embodiment, the material of the fixed rod 1 and the movable rod 2 is preferably carbon steel.

[0104] It should be noted that the structures of the fixed rod 1 and the movable rod 2 in this embodiment are preferably hollow structures. In this way, while ensuring the rigidity and strength of the fixed rod 1 and the movable rod 2 themselves, the weight of the fixed rod 1 and the movable rod 2 themselves can be reduced, making them lighter and more in line with people's needs, and can further reduce transportation costs (because the larger the volume and heavier the weight of the object, the higher the transportation cost).

[0106] The utility model also provides a storage rack, which includes the foldable protection frame mentioned above.

[0107] Among them, the storage rack in this embodiment is preferably a multi-layer storage rack, which is composed of multiple storage racks and support rods arranged at the four corners of the storage racks, and the foldable protection frame in this embodiment is placed on the vertical rods between two adjacent layers of storage racks, or on the vertical rods on the top layer of storage racks, so as to increase the firmness and stability of the multi-layer storage rack.
