[0044] Reference Figure 1 As shown, this application embodiment provides a quick-release double-layer slot fastening assembly, including:

[0045] The bracket 1 has an inner cavity 11, and the bracket 1 also has a first side 12 and a second side 13;

[0046] The cover 2 is inserted through the first side 12. The end side of the cover 2 extends to form a protrusion 21. The protrusion 21 forms a first slot 22 on the outer wall of the bracket 1. The first slot 22 is used to install the first plate 4.

[0047] A handle portion 3 is inserted through the middle of the bracket 1. The handle portion 3 has a first end 31 and a second end 32. The first end 31 of the handle portion 3 passes through the inner cavity 11 of the bracket 1. The second end 32 of the handle portion 3 forms a second slot 33 with the outer wall of the bracket 1. The second slot 33 is used to install the second plate 5.

[0048] The second side 13 extends in a direction away from the first side 12 to form a connecting part 14. The connecting part 14 passes through the substrate 6 and is used to connect the substrate 6 and the support 1.

[0049] The cover 2 moves relative to the bracket 1 to install and unload the first plate 4, and the handle 3 moves relative to the bracket 1 to install and unload the second plate 5.

[0050] according to Figure 1 Those skilled in the art can connect the first plate 4, the second plate 5, and the base plate 6 by setting a connection structure between the bracket 1, the cover 2, and the handle 3.

[0051] Specifically, a first slot 22 is formed between the cover 2 and the bracket 1, so that the first plate 4 can be inserted into the first slot 22 to complete the installation of the first plate 4; a second slot 33 is formed between the handle 3 and the bracket 1, so that the second plate 5 can be inserted into the second slot 33 to complete the installation of the second plate 5.

[0052] Furthermore, those skilled in the art can configure the cover 2 and the bracket 1 to slide relative to each other, thereby unloading the first plate 4 by sliding the cover 2. Correspondingly, those skilled in the art can configure the handle 3 to also move relative to the bracket 1, thereby unloading the second plate 5.

[0053] according to Figure 2 Those skilled in the art can configure the cover 2 to pass through the inner cavity 11 of the bracket 1, with the end side of the cover 2 extending to form a protrusion 21, and the protrusion 21 forming a first groove 22 on the outer wall of the bracket 1. The handle 3 has a first end 31 and a second end 32, with the first end 31 passing through the inner cavity 11 of the bracket 1, and the second end 32 of the handle 3 forming a second groove 33 on the outer wall of the bracket 1.

[0054] With the above structure, a first slot 22 can be formed between the cover 2 and the bracket 1, and a second slot 33 can be formed between the handle 3 and the bracket 1, thereby enabling the installation of the first plate 4 and the second plate 5.

[0055] For the connection of the substrate 6, the second side 13 extends in a direction away from the first side 12 to form a connecting part 14. The connecting part 14 passes into the substrate 6, thereby completing the connection between the substrate 6 and the support 1.

[0056] In the above embodiments, those skilled in the art can configure the cover 2 to slide relative to the bracket 1, thereby enabling the installation and unloading of the first plate 4. Preferably, the cover 2 has a positioning rod located in the inner cavity 11, and a first elastic member 23 is connected to the outer wall of the positioning rod. The two ends of the first elastic member 23 respectively abut against the inner wall of the inner cavity 11 and the wall surface of the cover 2.

[0057] With the above structure, those skilled in the art can use the first elastic member 23 to compress the cover 2 in its natural state, allowing the cover 2 to contact the bracket 1 when compressed. In this contacting state, a first slot 22 is formed between the cover 2 and the bracket 1. If it is necessary to unload the first plate 4, the cover 2 can be compressed away from the location of the first plate 4, causing the cover 2 to press against the first elastic member 23. Moving the cover 2 away from the location of the first plate 4 opens the first slot 22, allowing the first plate 4 to be unloaded. After the unloading action is completed, the cover 2 can be pushed back to its original position by the resetting action of the first elastic member 23.

[0058] It is understood that in the above embodiments, the first elastic member 23 is connected to the outer wall of the positioning rod, so as to protect the relative position of the first elastic member 23 and make the process of moving and resetting the cover 2 more stable.

[0059] In the arrangement of the handle portion 3, preferably, a second elastic member 34 is sleeved on the middle position of the handle portion 3, the second elastic member 34 is located in the inner cavity 11, and the two ends of the second elastic member 34 abut against the inner wall of the inner cavity 11 and the handle portion 3, respectively.

[0060] With the above structure, those skilled in the art can arrange the two ends of the second elastic member 34 to abut against the inner wall of the inner cavity 11 and the handle portion 3, so that the handle portion 3 can abut against the bracket 1 in its natural state. The abutment between the handle portion 3 and the bracket 1 forms a second slot 33, which allows the second plate 5 to be installed. If it is necessary to unload the second plate 5, the handle portion 3 can be pressed away from the location of the second plate 5, thereby pressing the second elastic member 34. The cover portion 2 moves away from the location of the second plate 5, which opens the second slot 33, thereby allowing the second plate 5 to be unloaded. After the unloading action is completed, the handle portion 3 can be pushed back to its original position by the reset action of the second elastic member 34.

[0061] In summary, those skilled in the art have designed the first elastic element 23 and the second elastic element 34 so that the cover 2 and the handle 3 can be reset after movement, making the use of the quick-release double-layer slot fastening assembly more convenient.

[0062] To facilitate the connection of the substrate 6, preferably, the second side 13 of the bracket 1 also has a positioning post 15, which is inserted into the substrate 6 and used to position the bracket 1 and the substrate 6 for installation.

[0063] With the above structure, a positioning post 15 is provided on the second side 13, and the positioning post 15 extends toward the substrate 6. During the installation of the substrate 6, the positioning post 15 and the connecting part 14 are simultaneously inserted into the substrate 6.

[0064] It is understood that those skilled in the art would set the positioning post 15 and the connecting part 14 to have at least unequal outer diameters, so as to position the substrate 6 for mounting.

[0065] In the above embodiment, the mounting process of the substrate 6 is completed by the connection part 14 passing through the substrate 6. Preferably, the end of the connection part 14 away from the bracket 1 is separated to form two connection ends 141, and the sidewalls of the two connection ends 141 that are far apart are inclined surfaces.

[0066] With the above structure, the two connecting ends 141 are simultaneously inserted into the substrate 6, and the two connecting ends 141 abut against the inner wall of the substrate 6, thereby enabling the substrate 6 to be installed.

[0067] More preferably, a connection hole 61 is provided on the substrate 6. The connection hole 61 is used to cooperate with the connection part 14. The maximum inner diameter of the connection hole 61 is less than the maximum distance between the sidewalls of the two connection ends 141 that are far apart.

[0068] That is, both connecting ends 141 are simultaneously inserted into the connecting hole 61, and the maximum inner diameter of the connecting hole 61 is less than the maximum distance between the far sidewalls of the two connecting ends 141. This arrangement allows the two connecting ends 141 to be squeezed closer together during insertion. After being squeezed, the two connecting ends 141 can abut against the inner wall of the connecting hole 61.

[0069] In one embodiment, the sidewalls of the two connecting ends 141 that are far apart are sloped and have stepped portions, so that the edge of the connecting hole 61 abuts against the stepped portions, thereby completing the fixation of the substrate 6 after installation. It is understood that setting the sidewalls of the two connecting ends 141 that are far apart as sloped can make the process of inserting the two connecting ends 141 more stable.

[0070] In the further configuration of the substrate 6, preferably, a positioning hole 62 is provided on the substrate 6, which is used to cooperate with the positioning post 15. The cooperation between the positioning hole 62 and the positioning post 15 facilitates the positioning of the substrate 6 during installation.

[0071] In one optional implementation, preferably, the plane containing the first plate 4 is parallel to the plane containing the second plate 5. That is, in this embodiment, the two parallel first plates 4 and second plates 5 can be fixed by the first slot 22 and the second slot 33.

[0072] Preferably, a first abutting part 16 is provided between the positioning post 15 and the connecting part 14. The first abutting part 16 protrudes from the second side 13 and abuts against the substrate 6.

[0073] With the above structure, the first abutting part 16 can come into contact with the substrate 6 during the mounting process. During the contact, the first abutting part 16 can be squeezed and moved, thus giving it a tendency to return to its original position. This tendency of the first abutting part 16 to return to its original position allows the substrate 6 to be held firmly, thereby making the structure of the substrate 6 more stable after mounting.

[0074] In the further configuration of the handle portion 3, preferably, two second abutting portions 35 are symmetrically provided on the second end portion 32 of the handle portion 3, the two second abutting portions 35 are located in the inner cavity, and the two second abutting portions 35 respectively abut against two opposite side walls in the inner cavity 11.

[0075] With the above structure, the two abutting parts 35 on the handle part 3 can make the handle part 3 abut against the inner wall of the inner cavity 11 in the installed structure, thereby fixing the relative position of the handle part 3.

[0076] Although different specific embodiments are mentioned in this application, this application is not limited to the situations described in industry standards or embodiments. Slightly modified implementations based on certain industry standards or custom methods or embodiments can also achieve the same, equivalent, or similar, or predictable, implementation effects as the above embodiments. Embodiments applying these modified or modified data acquisition, processing, output, and judgment methods still fall within the scope of optional implementations of this application.
