The support foot portion includes a support foot, the support arm portion includes a support arm, and the locking device includes a locking part, which includes a first locking part and a first locking mating part. The first locking part is located on the support arm, and the first locking mating part is located on the support foot. The first locking part and the first locking mating part are connected to lock the support arm to the support foot. The first locking part is a second hook, and the first locking mating part is a first locking opening, with the second hook hooked onto the first locking opening. Alternatively, the first locking mating part is a second hook, the first locking part is a first locking opening, and the second hook hooked onto the first locking opening.

[0004] The beneficial effects of this utility model are as follows: This utility model provides a frame comprising: a support arm portion; a support foot portion for supporting the support arm portion; and a locking device for detachably locking the support arm portion to the support foot portion.

[0031] Reference Figure 1-24 A shelf, comprising:

[0032] Support arm part 1;

[0033] Support leg part 2, which is used to support support arm part 1;

[0034] Locking device 3 is used to detachably lock the support arm part 1 to the support foot part 2.

[0035] With the above structure, including: a support arm portion 1; a support foot portion 2, which supports the support arm portion 1; and a locking device 3, which detachably locks the support arm portion 1 to the support foot portion 2, the support arm portion 1 and the support foot portion 2 can be locked together through the locking device 31, making the installation and disassembly of the support arm portion 1 and the support foot portion 2 simpler and faster. Furthermore, during the installation and disassembly of the support foot portion 2 and the support arm portion 1, it is only necessary to release the locking device from the support foot portion and the support arm portion, without damaging the support foot portion 2 and the support arm portion 1. This allows the frame to be repeatedly installed and disassembled to meet the user's needs in different scenarios. For example, it facilitates the user to disassemble the frame before moving it, and also facilitates the user to reinstall the frame after moving it.

[0036] In this embodiment, the support leg portion 2 has multiple support legs 21, the support arm portion 1 includes multiple support arms 11, and the locking device 3 includes multiple locking portions 31. The support legs 21 and the support arms 11 are detachably connected through the locking portions 31, so that the multiple support legs 21 and the multiple support arms 11 are interconnected and combined into a whole. Through the above structure, the support legs 21 and the support arms 11 are detachably connected through the locking portions 31, so that the multiple support legs 21 and the multiple support arms 11 are interconnected and combined into a whole. This makes it convenient for users to assemble and disassemble the frame, improving the efficiency of frame assembly and disassembly.

[0037] In this embodiment, the support foot portion 2 includes a support foot 21, the support arm portion 1 includes a support arm 11, and the locking device 3 includes a locking portion 31. The locking portion 31 includes a first locking part 311 and a first locking engagement part 312. The first locking part 311 is disposed on the support arm 11, and the first locking engagement part 312 is disposed on the support foot 21. The first locking part 311 and the first locking engagement part 312 are connected to lock the support arm 11 to the support foot 21. Wherein, the first locking part 311 is a first elastic wall 3111, the first locking mating part 312 is a first locking opening 3121, the first elastic wall 3111 is connected to the first locking opening 3121, and the first elastic wall 3111 is pressed and locked against the inner wall of the first locking opening 3121; or, the first locking mating part 312 is a first elastic wall 3111, the first locking part 311 is a first locking opening 3121, the first elastic wall 3111 is connected to the first locking opening 3121, and the first elastic wall 3111 is pressed and locked against the inner wall of the first locking opening 3121. Specifically, the first elastic wall 3111 includes a protruding first sidewall 3112 and a second sidewall 3113, the first sidewall 3112 and the second sidewall 3113 are connected, the first sidewall 3112 and the second sidewall 3113 are set at an obtuse angle, an acute angle or a right angle, and there is a first elastic gap 3114 between the first sidewall 3112 and the second sidewall 3113; or, the first elastic wall (3111) includes a protruding first sidewall (3112) and a second sidewall (3113), the first sidewall (3112) and the second sidewall (3113) are connected, and the first sidewall and the second sidewall are in contact with each other. With the above structure, when the first elastic wall 3111 is inserted into the first locking port 3121, the first elastic wall 3111 is squeezed within the range of the first elastic gap 3114. The elastic restoring force generated when the first elastic wall 3111 is squeezed pushes the first elastic wall 3111 to squeeze and lock the inner wall of the first locking port 3121, so as to squeeze and lock the support foot 21 to the support arm 11, thus completing the installation between the support foot 21 and the support arm 11 simply and quickly. Furthermore, when it is necessary to detach the support leg 21 from the support arm 11, it is only necessary to apply an external force greater than the elastic restoring force generated when the first elastic wall 3111 is compressed to push the first elastic wall 3111 out of the first locking hole 3121, so that the first elastic wall 3111 and the first locking hole 3121 are separated from each other, and the support arm 11 can be detached from the support leg 21. In the process of detaching the support arm 11 from the support leg 21, the structure of the support arm 11, the support leg 21, the first elastic wall 3111 and the first locking hole 3121 will not be damaged. This facilitates the reinstallation of the support arm 11 and the support leg 21, and the frame remains stable after the reinstallation.

[0038] In this embodiment, the locking portion 31 further includes a second locking portion 313 and a second locking engagement portion 314. The second locking portion 313 is disposed on the support arm 11, and the second locking engagement portion 314 is disposed on the support foot 21. The second locking portion 313 and the second locking engagement portion 314 are connected to lock the support arm 11 to the support foot 21. The locking portion 31 also includes a first connecting sidewall 315, through which the first locking portion 311 and the second locking portion 313 are connected.

[0039] Reference Figure 1-12The second locking part 313 is the first hook 3131, and the second locking mating part 314 is the second locking opening 3141. The first hook 3131 is hung on the second locking opening 3141. When the first elastic wall 3111 is connected to the first locking opening 3121, and the first elastic wall 3111 is pressed and locked against the inner wall of the first locking opening 3121, the first connecting side wall 315 pulls the first hook 3131 towards the first elastic wall 3111, so that the first connecting side wall 315 presses the first hook 3131 against the inner wall of the second locking opening 3141; or The second locking engagement part 314 is the first hook 3131, and the second locking part 313 is the second locking opening 3141. The first hook 3131 is hung on the second locking opening 3141. When the first elastic wall 3111 is connected to the first locking opening 3121 and the first elastic wall 3111 is pressed and locked against the inner wall of the first locking opening 3121, the first connecting side wall 315 pulls the first hook 3131 towards the first elastic wall 3111 so that the first connecting side wall 315 presses the first hook 3131 against the inner wall of the second locking opening 3141. With the above structure, when the first elastic wall 3111 is inserted into the first locking port 3121, the first elastic wall 3111 is compressed within the range of the first elastic gap 3114. The elastic restoring force generated when the first elastic wall 3111 is compressed pushes the first elastic wall 3111 to press and lock against the inner wall of the first locking port 3121, so as to press and lock the support foot 21 to the support arm 11, forming the first-level locking between the support foot 21 and the support arm 11; the first hook 3131 is hung on the second locking port 3141, when the first elastic wall When the first elastic wall 3111 is connected to the first locking port 3121, and the first elastic wall 3111 is pressed and locked against the inner wall of the first locking port 3121, the first connecting side wall 315 pulls the first hook 3131 towards the first elastic wall 3111, so that the first connecting side wall 315 presses the first hook 3131 against the inner wall of the second locking port 3141, forming a second-level locking between the support leg 21 and the support arm 11. The double locking design makes the connection between the support arm 11 and the support leg 21 more stable, making the frame less prone to loosening and ensuring high safety. Furthermore, the locking between the first elastic wall 3111 and the first locking port 3121 can prevent the support arm 11 and the support foot 21 from shifting vertically. At the same time, the first elastic wall 3111 is pressed and locked against the inner wall of the first locking port 3121, which can prevent the first elastic wall 3111 from disengaging from the first locking port 3121 and prevent the support arm 11 and the support foot 21 from shifting horizontally. The connection between the first hook 3131 and the second locking port 3141 can further prevent the support arm 11 and the support foot 21 from shifting horizontally, thereby strengthening the connection between the support arm and the support foot 21.

[0040] Reference Figure 19-24The locking portion 31 further includes a second locking portion 313 and a second locking mating portion 314. The second locking portion 313 is disposed on the support arm 11, and the second locking mating portion 314 is disposed on the support foot 21. The second locking portion 313 and the second locking mating portion 314 are connected to lock the support arm 11 to the support foot 21. The locking portion 31 also includes a first connecting sidewall 315, through which the first locking portion 311 and the second locking portion 313 are connected. Specifically, the first locking portion 311 is a second hook 301, and the first locking mating portion 312 is a first locking opening 3121, with the second hook 301 hooked onto the first locking opening 3121; or, the first locking mating portion 312 is a second hook 301, the first locking portion 311 is a first locking opening 3121, with the second hook 301 hooked onto the first locking opening 3121. Specifically, the second locking part 313 is the first hook 3131, and the second locking mating part 314 is the second locking opening 3141. The first hook 3131 is hooked onto the second locking opening 3141. When the second hook 301 is hooked onto the first locking opening 3121 and the first hook 3131 is hooked onto the second locking opening 3141, the first connecting sidewall pulls the first hook and the second hook together, so that the first hook 3131 is pressed against the inner wall of the second locking opening 3141 and the second hook 301 is pressed against the inner wall of the first locking opening 3121. Alternatively, the second locking engagement part 314 can be a first hook 3131, and the second locking part 313 can be a second locking opening 3141. The first hook 3131 is hooked into the second locking opening 3141. When the second hook 301 is hooked into the first locking opening 3121 and the first hook 3131 is hooked into the second locking opening 3141, the first connecting sidewall pulls the first hook and the second hook together, so that the first hook 3131 is pressed against the inner wall of the second locking opening 3141, and the second hook 301 is pressed against the inner wall of the first locking opening 3121. The first hook, the second hook, or the first connecting sidewall is elastic. With the above structure, the distance between the first hook and the second hook is less than the distance between the first locking opening and the second locking opening, so that the first hook connects to the second locking opening. When the second hook connects to the first locking opening, the first hook and the second hook are elastically pulled together. Specifically, the first hook extends toward the second hook, and the second hook extends toward the first hook.

[0041] Reference Figure 13-18The second locking part 313 is a second elastic wall 3132, the second locking mating part 314 is a second locking opening 3141, the second elastic wall 3132 is connected to the second locking opening 3141, and the second elastic wall 3132 is pressed and locked against the inner wall of the second locking opening 3141; or, the second locking mating part 314 is a second elastic wall 3132, the second locking part 313 is a second locking opening 3141, the second elastic wall 3132 is connected to the second locking opening 3141, and the second elastic wall 3132 is pressed and locked against the inner wall of the second locking opening 3141. The second elastic wall 3132 includes a protruding third sidewall 3133 and a fourth sidewall 3134. The third sidewall 3133 and the fourth sidewall 3134 are connected and are arranged at an obtuse angle, an acute angle or a right angle. A second elastic gap 3135 exists between the third sidewall 3133 and the fourth sidewall 3134. Alternatively, the second elastic wall 3132 includes a protruding third sidewall 3133 and a fourth sidewall 3134. The third sidewall 3133 and the fourth sidewall 3134 are connected and are in contact with each other. With the above structure, when the first elastic wall 3111 is inserted into the first locking port 3121, the first elastic wall 3111 is compressed within the range of the first elastic gap 3114. The elastic restoring force generated when the first elastic wall 3111 is compressed pushes the first elastic wall 3111 to press and lock against the inner wall of the first locking port 3121, so as to press and lock the support foot 21 to the support arm 11, forming the first-stage locking between the support foot 21 and the support arm 11; the second elastic wall 3132 is inserted into the second locking port. When the locking opening 3141 is tightened, the second elastic wall 3132 is compressed within the range of the second elastic gap 3135. The elastic restoring force generated when the second elastic wall 3132 is compressed pushes the second elastic wall 3132 to press and lock against the inner wall of the second locking opening 3141, so as to press and lock the support foot 21 to the support arm 11, forming a second-level locking between the support foot 21 and the support arm 11. The double locking design makes the connection between the support arm 11 and the support foot 21 more stable, making the frame less prone to loosening and ensuring high safety.

[0042] In this embodiment, the locking part 31 further includes a first connecting sidewall 315. The first connecting sidewall 315 is an elastic first connecting sidewall 315. The first locking part 311 and the second locking part 313 are connected through the first connecting sidewall 315. The first connecting sidewall 315 includes a first connecting wall 3151 and a second connecting wall 3152. The first connecting wall 3151 is connected to the first locking part 311, and the second connecting wall 3152 is connected to the second locking part 313. The first connecting wall 3151 and the second connecting wall 3152 are set at an obtuse angle, an acute angle, or a right angle, and a third elastic gap 3153 exists between the first connecting wall 3151 and the second connecting wall 3152. With the above structure, since a third elastic gap 3153 is provided between the first connecting wall 3151 and the second connecting wall 3152, the first connecting wall 3151 and the second connecting wall 3152 can approach or move away from each other within the range of the third elastic gap 3153, so that the first connecting side wall 315 can be compressed or stretched. When the first locking part 311 is connected to the first locking mating part, the first connecting side wall is stretched. The elastic restoring force generated when the first connecting side wall is stretched can pull the first locking part 311 and the second locking part 313 together, so that the first elastic wall 3111 is further squeezed and locked to the inner wall of the first locking port 3121, and the second elastic wall 3132 or the first hook 3131 is further squeezed and locked to the inner wall of the second locking port 3141.

[0043] In this embodiment, the support arm 11 has a first connecting portion 111, a first extension portion 112, and a support portion 113. Both ends of the first extension portion 112 are connected to the first connecting portion 111, and a first locking portion 311 is provided on the first connecting portion 111. The support portion 113 supports the shelf 4 and extends from the first extension portion 112 and / or the first connecting portion 111.

Specifically, the first connecting portion 111, the first extension portion 112, and the support portion 113 are integrally formed and connected. With the above structure, the support arm 11 has higher overall strength because the first connecting part 111, the first extension part 112, and the support part 113 are integrally formed and connected. Furthermore, the support part 113 supports the shelf 4, facilitating the installation of the shelf 4 and allowing users to place items on it. The support part 113 is located between the top and bottom of the first extension part 112 and / or between the top and bottom of the first connecting part 111, forming a receiving groove 6 for placing the shelf 4 between the support part 113 and the first extension part 112 and / or the first connecting part 111.

[0044] In this embodiment, the support foot 21 includes a first support sidewall 211 and a second support sidewall 212. The first support sidewall 211 and the second support sidewall 212 are connected, and the first support sidewall 211 and the second support sidewall 212 are set at an obtuse angle, a right angle, or an acute angle. Both the first support sidewall 211 and the second support sidewall 212 are provided with a first locking engagement part 312. With the above structure, both the first support sidewall 211 and the second support sidewall 212 are provided with a first locking engagement part 312 that is connected to the first locking part 311 of the support arm 11, so that both the first support sidewall 211 and the second support sidewall 212 can be connected to the support arm 11. Since the first support sidewall 211 and the second support sidewall 212 are set at an obtuse angle, a right angle, or an acute angle, the support arm 11 connected to the first support sidewall 211 and the support arm connected to the second support sidewall 212 extend in different directions, so that multiple support arms 11 and multiple support feet 21 are interconnected to form a frame.
