Description

Technical Field

[0001] The utility model belongs to the field of office furniture, and in particular relates to a novel table frame connection structure. Background Art

[0002] Metal table frames are widely used in our daily lives. Common products such as dining tables used in homes and restaurants, as well as negotiation and conference tables used in offices, often use metal as the frame material. Currently, most metal table frames on the market are either monolithic structures consisting of two sets of left and right legs and two crossbeams, or split structures consisting of four legs and a crossbeam. Monolithic structures offer greater strength and structural stability, but they are bulky and have high shipping costs. Split structures consist of two parts, a crossbeam and legs, connected by screws. This results in a smaller overall packaging volume and lower shipping costs, but ensuring the stability of the connection between the legs and the frame is difficult to achieve. Furthermore, the frames are often connected using gas welding, arc welding, or CO2 gas shielded welding, leaving weld scars exposed. The resulting cosmetic defects require manual processing, increasing product costs and easily causing defects. Utility Model Content

[0003] In order to make up for the deficiencies of the prior art, the present invention aims to provide a novel table frame connection structure, which connects the tabletop frame and table legs through connecting parts, thereby hiding welding marks while ensuring assembly strength.

[0004] The technical problem solved by the present invention can be achieved through the following technical solutions:

[0005] The novel table frame connection structure described includes a desktop frame and table legs. The desktop frame is formed by enclosing a number of beams end to end. The ends of two adjacent beams cooperate with connecting parts to assemble with the table legs. The connecting parts include an integrally arranged fixing plate, a connecting plate and a plug-in plate. The fixing plate, the connecting plate and the plug-in plate are arranged on the same center line. The fixing plate and the plug-in plate are parallel to each other and arranged perpendicular to the connecting plate. One side of the connecting plate is connected to the fixing plate and the other side is connected to the plug-in plate. The two ends of the plug-in plate are plugged into the positioning grooves provided on the beams. The fixing plate is fastened to the ends of the beams and the table legs by fastening bolts.

[0006] Furthermore, the connecting plate is an isosceles trapezoidal structure, with its short side wall connected to the fixed plate and the long side wall connected to the plug-in plate. The long side walls of the connecting plate extend from both ends of the plug-in plate to form plug-ins, which are plugged into the corresponding positioning grooves provided on the two beams.

[0007] Furthermore, the width of the fixing plate is narrower than the short side wall of the connecting plate, and a fastening hole is provided in the middle of the fixing plate.

[0008] Furthermore, the table legs are cylindrical tubes, and the ends of the beams are arranged as arc-shaped openings, and the table legs fit into the arc-shaped openings; and the two adjacent ends of the beams are cooperatively provided with assembly holes, the positions of the assembly holes correspond to the fastening holes on the fixing plate, and the fastening bolts are fixed to the table legs after passing through the fastening holes and the assembly holes in sequence.

[0009] Furthermore, an arc lining is provided in the table leg, the arc lining is fitted with the inner wall of the cylindrical tube, a nut is welded on the arc lining, and screw holes are provided in the arc lining and the cylindrical tube at positions corresponding to the nut.

[0010] Furthermore, a table top is provided on the table top frame, and the connecting plate is fixed to the table top with fasteners.

[0011] Furthermore, an upper opening groove is provided in the middle of the plug board.

[0012] Compared with the prior art, the utility model has the following advantages:

[0023] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the present invention is further described below with reference to the accompanying drawings.

[0024] like Figures 1-4 As shown, a new table frame connection structure includes a desktop frame 1 and table legs 2. The desktop frame 1 is formed by enclosing a plurality of beams 11 end to end. The ends of two adjacent beams 11 cooperate with connectors 3 to assemble with the table legs 2. The connector 3 includes an integral fixed plate 31, a connecting plate 32 and a plug-in plate 33. The fixed plate 31, the connecting plate 32 and the plug-in plate 33 are arranged on the same center line. The fixed plate 31 and the plug-in plate 33 are parallel to each other and perpendicular to the connecting plate 32. One side of the connecting plate 32 is connected to the fixed plate 31 and the other side is connected to the plug-in plate 33. The two ends of the plug-in plate 33 are plugged into the positioning grooves 111 provided on the beam 11. The fixed plate 31 is fastened to the ends of the beam 11 and the table legs 2 by fastening bolts.

[0025] It can be understood that positioning grooves 111 are opened at both ends of the beam 11 to cooperate with the plug-in plate 33 for positioning before welding, and then the inner side of the splicing is fully welded, which can eliminate the need for welding fixtures to improve welding efficiency and reduce production costs. Secondly, the plug-in connection method is adopted, and the overall structure is more solid, preventing problems such as false welding and cold welding during the welding process. Finally, the welding method on the inside of the connecting part can also hide the welding marks on the overall appearance to ensure the beauty of the product.

[0026] The connector of this application is made of 4mm thick sheet metal stamping, which ensures its overall high strength and firm and stable structure. Figure 5 As can be seen, the connecting plate 32 is an isosceles trapezoidal structure, with its short sidewalls connected to the fixed plate 31 and its long sidewalls connected to the plug-in plate 33. The plug-in plate 33 extends beyond the long sidewalls of the connecting plate 32 at both ends, forming inserts 331 that plug into the corresponding positioning slots 111 provided on the two crossbeams 11. A tabletop is provided on the desktop frame 1, and the connecting plate 32 is secured to the tabletop with fasteners. The fixed plate 31 is narrower than its short sidewalls, and a fastening hole 311 is provided in its center.

[0027] like Figure 5 As shown, the table leg 2 is a cylindrical tube, and the end of the crossbeam 11 is set as an arc-shaped opening, which fits the table leg 2; and the ends of the two adjacent crossbeams 11 are matched with assembly holes 112 (assembly holes 112 are evenly distributed on the ends of the two crossbeams 11, that is, the ends of the two crossbeams 11 are combined to form the hole). The position of the assembly hole 112 corresponds to the fastening hole 311 on the fixing plate 31. The fastening bolts pass through the fastening hole 311 and the assembly hole 112 in sequence and are fixed to the table leg 2. In order to facilitate the assembly of the fixing plate 31 and the end of the crossbeam, an upper opening groove 332 is set in the middle of the plug-in plate 33 (that is, the position corresponding to the fastening hole 311). Figure 6 As shown, in order to ensure the stability of the overall connection and the strength of the table leg connection, an arc lining 4 is provided in the table leg 2, and the arc lining 4 is fitted with the inner wall of the cylindrical tube. A nut 41 is welded on the arc lining 4, and screw holes are provided in the arc lining 4 and the cylindrical tube at positions corresponding to the nut 41.

[0028] It can be understood that the two end faces of the beam 11 are laser cut into an R38mm arc shape (i.e., an arc-shaped opening), and the radius is equal to that of the table leg 2. When the beam 11 is spliced with the table leg 2, the fastening bolts are passed through the fastening holes 311 on the fixing plate 31 and are fastened together with the nuts 41 on the inner arc lining 4 of the table leg 2. The arc-shaped opening at the end of the beam 11 can completely match the outer contour of the table leg, which has the effect of tightening and preventing the screws from loosening, making the overall structural strength more stable and the appearance beautiful.

[0029] The table frame of the present application can be disassembled into a bulk mode of desktop frame 1 and table legs 2. When packaging, the desktop frame 1 is connected to the connector 3 before leaving the factory, and the table legs 2 are placed in the desktop frame. The packaging is simple and the cost is low. When assembling, it is only necessary to take out the table legs and assemble them with the desktop frame and connector by fastening bolts. The installation is simple. Through the above overall design, the product has the characteristics of simplicity and practicality, efficient installation, low cost, good stability, and good appearance. In addition, the table frame connection structure of the present application is suitable for rock slabs, multi-layer boards, fireproof boards and other boards, and has strong versatility.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
