Description

Technical Field

[0001] The utility model belongs to the field of furniture structures, in particular to a supporting leg structure for a rectangular table. Background Art

[0002] Kit-style furniture tables are typically assembled from supporting legs, horizontal beams, vertical beams, and a tabletop. Their modular construction makes them easier to transport, significantly reducing storage requirements while also allowing users to assemble and disassemble them according to their needs. This flexibility and practicality have made them popular in the market and an indispensable part of modern home decor. However, existing kit-style furniture tables often have exposed joints, which detracts from their appearance and reduces the aesthetic appeal of the original design. Furthermore, some joints are weak, compromising their functionality. Utility Model Content

[0003] The top of the supporting leg is a notch structure, and the end connecting seat is fixedly installed in the notch structure. The end connecting seat comprises a U-shaped base and two U-shaped grooves, wherein one end of the U-shaped groove is welded and fixedly installed to the bottom of the U-shaped base and opens downward, and the other end of the U-shaped groove is welded and fixedly installed to the top of the U-shaped base and opens upward. One end of the U-shaped groove is flush with the side surface of the U-shaped base, and the other end of the U-shaped groove extends outside the U-shaped base. Both U-shaped grooves are provided with corresponding upper and lower coaxial through-holes. The U-shaped groove located at the bottom is fixedly installed with nuts at the through-holes. The two U-shaped grooves are inserted into the vertical beam and respectively fit with the inner upper surface and inner lower surface of the vertical beam. The upper surface of the vertical beam is provided with a fixing hole coaxial with the through-hole, and the vertical beam is fixedly installed to the supporting leg by bolts passing through the fixing holes and the through-holes at the same time and being threadedly connected with the nuts.

[0004] Among them, the support leg structure for a rectangular table also includes an extended support structure, the extended support structure includes two support legs, a crossbeam is fixedly installed between the two support legs, the top of the support leg is a slot structure, and a middle connecting seat is fixedly installed in the slot structure. The middle connecting seat includes a U-shaped base and two U-shaped grooves with the same structure as the end connecting seat. Both ends of the U-shaped groove of the middle connecting seat extend outside the U-shaped base, and the other structures of the middle connecting seat are the same as those of the end connecting seat.

[0005] A supporting platform is fixedly installed on the top of the U-shaped base, and the supporting platform is fixedly installed on the U-shaped base by bolts passing through two U-shaped grooves and cooperating with nuts.

[0006] Wherein, the U-shaped base is fixedly installed with a connecting groove on the other side relative to the supporting platform, and one end of the connecting beam is fixedly installed on the connecting groove by bolts.

[0007] The utility model has the beneficial effects:

[0008] 1. Fix the nut into the U-shaped groove of the end connector and combine it with the top-down bolt installation method to hide the nut in the vertical beam. Then use the table to cover the bolt from above to achieve a fully hidden assembly connection and enhance the overall appearance of the structure.

[0009] 2. The two U-shaped grooves respectively cooperate with the upper and lower inner surface gaps of the vertical beam to form support for the inside of the vertical beam, which can not only improve the structural strength of the connection, but also prevent the connection from swinging, thereby improving the overall assembly effect.

One end of the U-shaped groove 8 is flush with the side of the U-shaped base 7, and the other end of the U-shaped groove 8 extends outside the U-shaped base 7. The two U-shaped grooves 8 are provided with four corresponding upper and lower coaxial through-holes 9. The U-shaped groove 8 located at the bottom is fixed with nuts at the through-holes 9. The two U-shaped grooves 8 are inserted into the vertical beam 3 and are respectively fitted with the inner upper surface and the inner lower surface of the vertical beam 3. The upper surface of the vertical beam 3 is provided with two fixing holes 10 coaxial with the through-hole 9. The vertical beam 3 is fixed to the support leg 4 by two bolts passing through the corresponding fixing holes 10 and through-hole 9 at the same time and being threadedly connected with the nuts. The extension support structure 2 includes two support legs 4, a crossbeam 5 is fixedly installed between the two support legs 4, the top of the support legs 4 is a notch structure, and a middle connecting seat 11 is fixedly installed in the notch structure.
