Description

Technical Field

[0001] This utility model mainly relates to the field of metal wardrobe production technology, specifically to a positioning structure for assembling metal wardrobe support legs. Background Technology

[0002] In the assembly of a metal wardrobe, the installation of the support legs is a crucial step in ensuring the stability of the cabinet. Typically, the bottom frame of a metal wardrobe is constructed from metal components such as side panels and a bottom plate, welded or bolted together. The support legs need to be installed at the four corners of the bottom of the cabinet. The specific process is as follows: First, mark the positioning points of the support legs in the pre-designed installation area on the bottom of the cabinet. Then, pass the uprights of the support legs through the pre-drilled holes in the bottom of the cabinet, ensuring the mounting plate of the support leg fits against the bottom surface of the cabinet. Next, secure the mounting plate to the cabinet using bolts. Finally, install the bottom plate of the support leg to complete the assembly of the load-bearing structure.

[0003] During the installation of the support legs, the positioning accuracy directly affects the stability of the cabinet. However, traditional methods rely on manual measurement and alignment, resulting in low installation efficiency.

[0004] On the one hand, the lack of a dedicated positioning structure makes it difficult to ensure the fit between the mounting plate of the support leg and the bottom of the cabinet, which can easily lead to tilting or displacement, resulting in uneven stress on the cabinet, shaking, or even tipping over. Installers need to keep their hands on the positioning throughout the process. On the other hand, existing positioning aids usually use a single specification of mounting holes, which cannot be compatible with support leg mounting plates of different shapes such as round and rectangular, and are also difficult to adapt to the size differences of support legs of different brands or models, resulting in poor versatility.

[0005] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0032] See attached document Figure 1-5 A positioning structure for assembling metal wardrobe support legs includes a support leg 1 and a positioning structure body. The positioning structure body includes a snap-fit ​​block 2 and a limiting block 3. The snap-fit ​​block 2 is provided with multiple elastic buckles 4. The snap-fit ​​block 2 has a through hole 201. The multiple elastic buckles 4 are all embedded in the through hole 201. Multiple sets of mounting holes 202 are provided around the through hole 201. The limiting block 3 is embedded in one side of the snap-fit ​​block 2 and slidably connected to it. The limiting block 3 includes a top pressure plate 301, a first limiting side plate 302, and a second limiting side plate 303. The lower end of the top pressure plate 301 is provided with a first slider 304 and a second slider 305 corresponding to the first limiting side plate 302 and the second limiting side plate 303.

[0033] This positioning structure mainly consists of support feet 1, snap-fit ​​blocks 2, and limit blocks 3. The three components work together mechanically to achieve rapid positioning and secure connection. Support feet 1 are the load-bearing components at the bottom of the metal wardrobe. Through the coordinated action of snap-fit ​​blocks 2 and limit blocks 3, they are precisely positioned and fixed at the four corners of the bottom of the wardrobe.

[0034] Support leg 1 is the basic load-bearing component of the metal wardrobe, including uprights, mounting plates, and a base plate. It is a vertical column structure made of steel pipe or aluminum alloy profile. Its outer diameter is adapted to the inner diameter of the through hole 201 of the snap-fit ​​block 2, and it can pass through the through hole 201 to achieve initial positioning. The mounting plate is a horizontal plate fixed to the top of the upright. It has a flat surface and holes corresponding to the mounting holes 202 of the snap-fit ​​block 2, which are used to fix it to the bottom of the wardrobe body with bolts. The base plate is located at the bottom of the upright and is detachably connected to the upright through a threaded structure. The base plate is removed first during initial positioning. Anti-slip rubber pads can be installed on the bottom surface of the base plate to enhance the stability of the support.

[0035] The snap-fit ​​block 2 is the core component of the positioning structure. It is rectangular in shape and its structural design takes into account both connection strength and adaptability. It includes a through hole 201, a mounting hole 202, a limiting slide 203, and a telescopic spring 204. The through hole 201 on the snap-fit ​​block 2 is located in the center of the snap-fit ​​block 2. It is a vertical through hole with an inner diameter slightly larger than the outer diameter of the support leg 1 column. It is used to accommodate the support leg 1 column and realize the initial positioning of the support leg 1.

[0036] At least three sets of mounting holes 202 are provided around the through hole 201. Each set contains 2-4 bolt holes in a rectangular arrangement, which correspond completely to the holes on the mounting plate of the support leg 1. The diameter of the mounting holes 202 is larger than the diameter of the holes on the mounting plate, and is used to fix the support leg 1 to the bottom of the wardrobe body with bolts.

[0037] The limiting slide 203 is provided on the two diagonal sides of the snap-fit ​​block 2. It is a groove structure extending along the diagonal direction and is used to cooperate with the slider of the limiting block 3 to realize the sliding guidance of the limiting block 3.

[0038] The telescopic spring 204 is installed inside the limiting slide 203. One end is fixed to the bottom of the slide, and the other end is connected to the slider of the limiting block 3, providing an inward elastic pulling force so that the limiting block 3 remains in a contracted state when no external force is applied.

[0039] The limiting block 3 is a sliding limiting adjustment mechanism, which is set in pairs at the diagonal of the snap-fit ​​block 2 to adapt to the right-angle edge of the wardrobe body and provide lateral limiting. It includes the top pressure plate 301, the limiting side plate 1 302 and the limiting side plate 2 303, which are integrally formed in an "L" shape.

[0040] The inner sides of the first limiting side plate 302 and the second limiting side plate 303 are respectively provided with the first slider 304 and the second slider 305, which are arranged diagonally and are respectively inserted into the limiting slides 203 on both sides of the snap-fit ​​block 2, and connected to the first telescopic spring 204, so that the limiting block 3 can slide along the diagonal direction.

[0041] The top pressure plate 301 has a dual limiting end face design, including a right-angle limiting end face 3011 and an arc-shaped limiting end face 3012: the right-angle limiting end face 3011 is two planar structures forming a right angle, used to match the edge of the rectangular mounting plate, and the radius of the arc-shaped limiting end face 3012 is an arc surface with the same outer diameter as the circular mounting plate, used to match the edge of the circular mounting plate. The two end faces are smoothly connected by transition fillets, so that the limiting block 3 can be compatible with support foot mounting plates of different shapes.

[0042] The inner surfaces of the limiting side plate 1 302 and the limiting side plate 2 303 are perpendicular to each other, forming a right angle. This angle matches the reserved spacing of the mounting hole 202 and the spacing between the right-angle edge of the metal wardrobe and the reserved hole at the bottom, thus achieving lateral positioning.

[0043] The elastic buckle 4 structure is placed inside the snap-fit ​​block 2 and extends out of the through hole 201. The telescopic spring 401 exerts a lateral pulling force on the snap-fit ​​block 402, squeezing the side wall of the support foot 1 column inserted into the through hole 201, thereby achieving horizontal positioning of the column. The elastic structure has a certain clamping range and can be used for columns of different diameters.

[0044] The location logic is as follows:

[0045] When the mounting plate of the support foot 1 passes through the snap-fit ​​block 2 and is pressed downward, the edge of the mounting plate pushes the limiting block 3 to slide outward along the limiting slide 203, compressing the telescopic spring 204. The elastic reaction force of the telescopic spring 204 makes the limiting block 3 press tightly against the right-angle edge of the wardrobe body. At the same time, the right-angle limiting end face 3011 or arc-shaped limiting end face 3012 on the side of the top pressure plate 301 fits tightly against the side of the mounting plate, forming an elastic clamping force to ensure the stability of the positioning of the support foot 1 during installation.

[0046] The mounting holes 202 of the snap-fit ​​block 2 are provided with multiple sets of holes with different spacings to adapt to standard specification support feet, widened specification support feet, or asymmetrical hole positions to adapt to specially designed support feet. By selecting different mounting holes, this positioning structure can adapt to support feet of various specifications. In another embodiment, the multiple sets of mounting holes 202 are replaced with oblong holes. The length of the oblong holes covers multiple hole positions with different spacings, which can realize more convenient hole positioning action.

[0047] The location process is as follows:

[0048] Place the snap-fit ​​block 2 at the bottom corner of the wardrobe cabinet, so that the right angle of the limiting block 3 is aligned with the right angle of the outer side of the cabinet.

[0049] The support leg 1 is passed through the through hole 201 of the snap-fit ​​block 2, and the mounting plate pushes the limit block 3 to slide outward and compress the telescopic spring 204.

[0050] The elastic reaction force of the telescopic spring 204 causes the limiting block 3 to clamp tightly against the edge of the cabinet, while the holes of the mounting plate and the mounting holes 202 of the snap-fit ​​block 2 are automatically aligned.

[0051] By passing bolts through the mounting holes 202 of the snap-fit ​​block 2 and the mounting plate of the support leg 1, the support leg 1 is securely connected to the bottom of the cabinet.

[0052] Disassemble the positioning structure (clamping block 2 and limiting block 3), and tighten the base plate of the support leg 1 to the column through threads to complete the installation.

[0053] In summary, the system utilizes elastic limit blocks to automatically align with the right-angled edges of the cabinet for rapid and precise positioning without the need for measurement. Through dual limit end faces and multiple sets of mounting holes, it adapts to rectangular or circular mounting plates and support feet of different specifications, achieving multi-specification compatibility. The positioning structure can be reused in the assembly of multiple wardrobes, offering a wide range of applications and reducing production costs.

[0054] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
