[0039] Example 1

[0040] See also Figure 1 Figure 2 , the present application provides a grid system 100. Among them, Figure 1 This is an axonometric view of the grid system 100 in Example 1 provided in this application; Figure 2 for Figure 1 Enlarged schematic diagram at A.

[0041] The grid system 100 includes a support assembly 10, a grid assembly 20, and a connector 30. The support assembly 10 includes a bracket 11. The grid assembly 20 is overlapped on the bracket 11. The connector 30 is rotatably connected to the bracket 11. As the connector 30 rotates, the connector 30 can press and fix the grid assembly 20 to the bracket 11, or the connector 30 can be detached from the grid assembly 20. It can be understood that by rotating the connector 30, the grid assembly 20 can be press and fixed to the bracket 11, or the grid assembly 20 can be detached from the grid assembly 20, thereby allowing the grid assembly 20 to be removed from the bracket assembly. Compared to related structures that use screws to connect the grid assembly 20 to the bracket 11, the grid system 100 provided in this application uses connectors 30 to connect the grid assembly 20 and the support assembly 10, which can improve assembly and disassembly efficiency.

[0042] See also Figure 2 as well as Figures 5 to 9 ,in, Figure 5 This is a schematic diagram of the connecting body 31 in the locked state in the first embodiment provided by the present application; Figure 6 for Figure 5 sectional view ofFigure 7 This is a schematic diagram of the connecting body 31 in the unlocked state in the first embodiment provided by this application; Figure 8 for Figure 7 sectional view of Figure 9 This is an axonometric view of the connecting body 31 in the first embodiment provided in this application.

[0043] The connector 30 includes a connecting body 31 and a locking portion 32 connected to the connecting body 31. The connecting body 31 has a rotating shaft 311 at one end and a cantilever 312 at the other end. The rotating shaft 311 is rotatably connected to the bracket 11, and the cantilever 312 is used to press and fix the grid assembly 20. The bracket 11 has a mating portion 111 corresponding to the locking portion 32. When the locking portion 32 is engaged with the mating portion 111, the connecting body 31 is in a locked state. When the locking portion 32 is disengaged from the mating portion 111, the connecting body 31 is in an unlocked state. It should be noted that "the connecting body 31 is in a locked state" means that the connecting body 31 cannot move relative to the bracket 11. By providing the locking portion 32, the connecting body 31 can be prevented from accidentally detaching from the grid assembly 20, thereby improving the reliability of the connecting body 30 in connecting the grid assembly 20 to the support assembly 10.

[0044] Specifically, the connecting body 31 is approximately L-shaped, with one end of the L-shaped connecting body 31 forming a cantilever 312 and the other end being provided with a rotating shaft 311. The bracket 11 has a receiving cavity 119. The connecting body 31 is located within the receiving cavity and is rotatably connected to the cavity walls on both sides of the receiving cavity 119 via the rotating shaft 311. The cantilever 312 can extend out of the receiving cavity 119 and cooperate with the end surface of the bracket 11 to clamp the grid assembly 20.

[0045] The mating portion 111 is configured as a through-slot 112 defined in the bracket 11. The locking portion 32 is movably connected to the connecting body 31. The bracket 11 further defines a first sliding slot 113, which communicates with the through-slot 112. The locking portion 32 can be disengaged from the through-slot 112 and enter the first sliding slot 113 by moving relative to the connecting body 31, or can be engaged with the through-slot 112 from the first sliding slot 113. In other words, when the locking portion 32 is located within the through-slot 112, the connecting body 31 is locked. By moving the locking portion 32 relative to the connecting body 31, the locking portion 32 can be disengaged from the through-slot 112 and enter the first sliding slot 113, thereby unlocking the connecting body 31.

[0046] Furthermore, the first sliding groove 113 is an arc-shaped groove extending along the rotation axis 311 , and the first sliding groove 113 is used for the locking portion 32 to rotate around the rotation axis 311 following the connecting member 30 in the unlocked state.

[0047] The connector 30 further includes a connecting rod 33, and the locking portion 32 is provided at one end of the connecting rod 33 and movably connected to the connecting body 31 via the connecting rod 33. The connecting rod 33 is used to movably connect the locking portion 32 to the connecting body 31.

[0048] A shifting block 331 is further provided on the end of the connecting rod 33 away from the locking portion 32. The shifting block 331 abuts against the end of the connecting body 31. When using the connector 30, the user pulls the shifting block 331 upward, causing the locking portion 32 to move upward along the through slot 112 until it disengages the through slot 112 and enters the first chute 113. Furthermore, when the locking portion 32 moves along the first chute 113 to the point where it connects with the through slot 112, the connecting rod 33 falls under its own weight, causing the locking portion 32 to reengage the through slot 112. Optionally, the connecting rod 33, the shifting block 331, and the locking portion 32 are integrally formed.

[0049] Please refer again Figure 1 The number of brackets 11 and the number of connectors 30 are both multiple and equal. The brackets 11 are spaced apart, and each connector 30 is rotatably connected to a corresponding bracket 11. In this way, each bracket 11 and the connector 30 provided on this bracket 11 form a mounting position, which not only improves the firmness of the connection between the grid assembly 20 and the support assembly 10, but also enables the grid assembly 20 to be freely adjusted between multiple mounting positions.

[0050] The grid assembly 20 includes a first grid 21 and a second grid 22. At least portions of the first grid 21 and the second grid 22 overlap along their lengths to form an overlapping region 23. Connectors 30 can be used to crimp and secure the overlapping region 23 to the bracket 11. In other words, the connectors 30 can also be used to connect the first grid 21 and the second grid 22.

[0051] Specifically, the first grid 21 and the second grid 22 are configured in multiple numbers, with the width of the first grid 21 being greater than that of the second grid 22. The multiple second grids 22 are arranged along their lengths, with each first grid 21 being nested at both ends with two adjacent second grids 22 to form an overlapping region 23. This allows users to adjust the length of the grid assembly 20 according to their needs.

[0052] Among them, the first grid 21 and the second grid 22 are configured to include a first support rod 241 and a second support rod 242 arranged in parallel, and a plurality of cross rods 25 are provided between the first support rod 241 and the second support rod 242. The two ends of each cross rod 25 are respectively connected to the first support rod 241 and the second support rod 242, and the plurality of cross rods 25 are arranged at intervals along the length direction of the first support rod 241.

[0053] See also Figure 2 and Figure 5Each bracket 11 is provided with two limiting grooves 11a arranged side by side, one limiting groove 11a is used to place the first support rod 241 of the first grid 21, and the other limiting groove 11a is used to place the first support rod 241 of the second grid 22. The cantilever 312 can crimp the first support rod 241 of the first grid 21 and / or the first support rod 241 of the second grid 22 to the bracket 11.

[0054] See also Figure 3 and Figure 5 The second support rod 242 is provided with a slot 243 , and one end of each bracket 11 away from the connector 30 is provided with a plug-in portion 13 , which can be differentially placed in the slot 243 to support the second support rod 242 .

[0055] See also Figure 4 The grid system 100 further includes a hook assembly 40, which is detachably mounted on the bracket 11. By providing the hook assembly 40, the storage function of the bracket 11 is expanded.

[0056] Further, if Figure 5 As shown, the connecting member 30 and the hook assembly 40 are respectively located at two opposite ends of the bracket 11.

[0057] See also Figure 5 、 Figure 6 and Figure 10 The hook assembly 40 includes a hook body 41 and an elastic connecting member 42 detachably connected to the hook body 41. The hook body 41 is provided with a hook 411, and the elastic connecting member 42 is provided with an elastic clamping portion 421. The bracket 11 is provided with a hanging hole 117 corresponding to the hook 411 and a through hole 118 corresponding to the elastic clamping portion 421; the hook 411 is hung on the bracket 11 through the hanging hole 117, and the elastic clamping portion 421 is clamped in the through hole 118, and the elastic clamping portion 421 can be deformed and disengaged from the through hole 118, so that the hook 411 can be disassembled and disengaged from the hanging hole 117.

[0058] It is understood that when the elastic latch 421 is engaged in the through hole 118, the elastic action of the elastic latch 421 allows the hook 411 to remain attached to the bracket 11, i.e., the hook assembly 40 is locked and connected to the bracket 11. When the elastic latch 421 deforms and disengages the through hole 118, the hook assembly 40 can adjust its angle to release the hook 411 from the hanging hole 117. In other words, the elastic latch 421 is used to lock or unlock the hook assembly 40.

[0059] Furthermore, the elastic engaging portion 421 includes a main body 421a and an elastic arm 421b connected to each other. One end of the elastic arm 421b is connected to the main body 421a, and the other end is suspended. When the elastic engaging portion 421 is engaged in the through hole 118, the elastic arm 421b is moved toward the main body 421a, causing the elastic arm 421b to elastically deform, reducing the width of the elastic engaging portion 421, thereby allowing it to be disengaged from the through hole 118.

[0060] The hook assembly 40 further includes a support member 43, which is disposed at one end of the hook body 41 away from the elastic connector 42 and has a groove 431 for placing items. The support member 43 expands the storage function of the hook assembly 40. For example, the groove 431 can be used to place the hanging rod 50.

[0061] Please continue reading Figure 1 The support assembly 10 further includes a plurality of vertical beams 12, the number of which is the same as the number of brackets 11. The vertical beams 12 are arranged at intervals, and a bracket 11 is detachably mounted on each vertical beam 12. Furthermore, the brackets 11 are triangular in structure, with the width of the brackets 11 closer to the vertical beams 12 being greater than the width of the brackets 11 farther from the vertical beams 12.

[0062] Furthermore, each vertical beam 12 is provided with a plurality of mounting positions 121 for mounting the bracket 11, and the plurality of mounting positions 121 are spaced apart along the height direction of the vertical beam 12. Each bracket 11 can be switched between the plurality of mounting positions 121 on the corresponding vertical beam 12 to adjust the installation height of the bracket 11.

[0063] Example 2

[0064] See also Figure 11 and Figure 12 ,in, Figure 11 This is a schematic diagram of the assembly of the bracket 11 and the connector 30 in the second embodiment provided in this application; Figure 12 for Figure 11 Side view of the middle connector 30.

[0065] This grid system 100 is similar to the grid system 100 of the first embodiment, and includes a support assembly 10, a grid assembly 20, and a connector 30. The connector 30 includes a connecting body 31 and a locking portion 32 connected to the connecting body 31. The connecting body 31 is provided with a rotating shaft 311 at one end and a cantilever 312 at the other end. The rotating shaft 311 is rotatably connected to the bracket 11. The cantilever 312 is used to press and fix the grid assembly 20. The bracket 11 is provided with a matching portion 111 corresponding to the locking portion 32. When the locking portion 32 is engaged with the matching portion 111, the connecting body 31 is in a locked state. When the locking portion 32 is disengaged from the matching portion 111, the connecting body 31 is in an unlocked state. The difference between this embodiment and the first embodiment is that the structures and matching forms of the connecting body 31, the locking portion 32, and the matching portion 111 are different. In this embodiment, the locking portion 32 is fixedly connected to the connecting body 31 , and the locking portion 32 can be elastically deformed in response to an external force to engage with the matching portion 111 or be disengaged from the matching portion 111 .

[0066] Specifically, the locking portion 32 is configured as an elastic latch 321 with a notch 322 defined therein. The bracket 11 has a second slot 114 corresponding to the elastic latch 321. The locking portion 32 is configured as a protrusion 115 defined on the second slot 114. The elastic latch 321 slides and engages within the second slot 114. In response to the compression of the protrusion 115, it deforms, allowing it to pass through the notch 322 and engage with or disengage from the protrusion 115. When the notch 322 engages with the protrusion 115, the elastic latch 321 cannot move further along the second slot 114, effectively locking the connecting body 31. When the notch 322 disengages from the protrusion 115, the connecting body 31 is unlocked. Thus, as the elastic latch 321 moves along the second slot 114, the connecting body 31 can be locked and unlocked, simplifying operation. The elastic latch 321 and the connecting body 31 are integrally configured.

[0067] Example 3

[0068] See also Figures 13 to 15 ,in, Figure 13 Schematic diagram of the assembly of the bracket 11 and the connector 30 in the third embodiment provided in this application Figure 1 ; Figure 14 Schematic diagram of the assembly of the bracket 11 and the connector 30 in the third embodiment provided in this application Figure 2 ; Figure 15 This is a schematic structural diagram of the connector 30 in the third embodiment provided in this application.

[0069] The net rack system 100 is similar to the net rack system 100 of embodiment one, comprising the support assembly 10, the net rack assembly 20 and the connecting piece 30, and the connecting piece 30 comprises the connecting body 31 and the locking portion 32 connected to the connecting body 31, one end of the connecting body 31 is provided with the rotating shaft 311, the other end is provided with the cantilever 312, the rotating shaft 311 is rotationally connected to the support 11, the cantilever 312 is used for crimping and fixing the net rack assembly 20, and the support 11 is provided with the matching portion 111 corresponding to the locking portion 32. When the locking portion 32 is clamped and matched with the matching portion 111, the connecting body 31 is in the locked state, and when the locking portion 32 is separated from the matching portion 111, the connecting body 31 is in the unlocked state. The difference between the embodiment and embodiment one is that the structure and matching form of the connecting body 31, the locking portion 32 and the matching portion 111 are different. In the embodiment, the matching portion 111 is configured as the clamping hole 116 opened on the support 11, the locking portion 32 is fixedly connected to the connecting body 31, the surface of the locking portion 32 is provided with the guide inclined surface 323, and the locking portion 32 can be clamped into or separated from the clamping hole 116 along the guide inclined surface 323. In this way, as the elastic clamping tongue 321 moves along the second sliding groove 114, the guide inclined surface 323 can guide the locking portion 32 to be clamped into or separated from the clamping hole 116, so as to realize the locking and unlocking of the connecting body 31, and the operation is simple.

[0070] Specifically, the surface of the locking portion 32 is provided with two guide inclined surfaces 323, and the two guide inclined surfaces 323 are both inclinedly arranged relative to the clamping hole 116, one of the two guide inclined surfaces 323 is used for guiding the locking portion 32 to be clamped into the clamping hole 116, and the other guide inclined surface 323 is used for guiding the locking portion 32 to be separated from the clamping hole 116.

[0071] In order to avoid that the locking portion 32 is completely separated from the support 11 after being separated from the clamping hole 116. Optionally, as shown in Figure 13 , the support 11 is provided with the limiting hole 11b, and when the locking portion 32 is clamped into the limiting hole 11b, the cantilever 312 remains separated from the net rack assembly 20. Or, as shown in Figure 14 , the other side of the connecting body 31 opposite to the locking portion 32 is also provided with the sliding block 34, the support 11 is provided with the second sliding groove 114 corresponding to the sliding block 34, and the second sliding groove 114 extends in a circular arc shape and around the rotating shaft 311. The movement track of the connecting body 31 is defined through the cooperation of the sliding block 34 and the second sliding groove 114, so that the connecting body 31 can rotate around the rotating shaft 311 more stably.

[0072] The technical features of the above-described embodiments can be combined arbitrarily, and in order to make the description simple, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope recorded in the present specification.

[0073] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of patent protection for the present application shall be determined by the appended claims.
