[0030] Schematic table leg and table frame quick assembly structure, reference Figures 1 to 7 According to a preferred embodiment of the present invention, a quick-install structure for table legs and table frames is provided. Figure 1 and Figure 2 As shown, the table comprises a table frame 10 , a side wing panel 20 and a table leg 30 .

[0031] Specifically, if Figure 3 As shown, the table frame 10 includes two tube bodies 101 and two connecting pieces 102 for connecting the two tube bodies 101. The two connecting pieces 102 are respectively located at the two ends of the two tube bodies 101, and the two ends of each connecting piece 102 are respectively connected to the two tube bodies 101. In the embodiment of the present application, the tube body 101 is a rectangular tube, and one connecting piece 102 located at one end of the table frame 10 close to the side wing plate 20 is located at the end of the table frame 10, and the other connecting piece 102 located at the end of the table frame 10 away from the side wing plate 20 is located at the top of the two table frames 10.

[0032] In addition, in order to facilitate the side wing plate 20 to be quickly connected to the tube body 101 in an inserting manner from top to bottom, as shown in FIG. Figure 3 and Figure 4 As shown, each of the tube bodies 101 has an insertion cavity 1011. More specifically, each of the tube bodies 101 has an insertion cavity 1011 at the top of one end close to the side wing plate 20, and the insertion cavity 1011 is a concave cavity with an opening at the top; in addition, the side wing plate 20 is arranged vertically to the table frame 10, and the side wing plate 20 has two insertion ends 201, and the insertion ends 201 correspond one-to-one to the insertion cavities 1011, and each of the insertion ends 201 is inserted into the corresponding insertion cavity 1011.

[0033] In addition, in order to realize the quick connection of the table legs 30 with the table frame 10 and the side wing panels 20 at the same time, Figure 3 and Figure 4 As shown, the two tube bodies 101 have a first L-shaped groove 1012 on one side facing each other, and the first L-shaped groove 1012 is connected to the insertion cavity 1011; in addition, each of the insertion ends 201 has a second L-shaped groove 2011, and the projections of the first L-shaped groove 1012 and the second L-shaped groove 2011 in the width direction of the table frame 10 coincide with each other; in addition, as shown Figure 5 As shown, one end of the table leg 30 has a box body 301, and two shaft bodies 3011 are provided on both sides of the box body 301. The box body 301 is placed in the two tube bodies 101, and each of the shaft bodies 3011 extends into the corresponding first L-shaped groove 1012 and the second L-shaped groove 2011.

[0034] It should be noted that, after each of the shaft bodies 3011 extends into the corresponding first L-shaped groove 1012 and the second L-shaped groove 2011, it abuts against the bottom of the first L-shaped groove 1012 and the second L-shaped groove 2011 at the same time, and the side wing plate 20 is blocked by the shaft body 3011 and cannot move upward and escape from the top opening of the insertion cavity 1011, and the horizontal movement of the side wing plate 20 and the table frame 10 is also restricted by the insertion end 201 into the insertion cavity. The box body 301 is restricted by the two tube bodies 101 on both sides, and one end of the box body 301 is restricted by the bottom of the first L-shaped groove 1012 and the second L-shaped groove 2011 due to the shaft body 3011. When the shaft body 3011 does not move toward the notch direction of the first L-shaped groove 1012 and the second L-shaped groove 2011, the table leg 30, the table frame 10 and the side wing panel 20 are quickly connected.

[0035] Furthermore, in order to prevent the shaft 3011 from moving toward the notch direction of the first L-shaped groove 1012 and the second L-shaped groove 2011, Figure 6 As shown, the table leg and table frame quick assembly structure further includes an insert 40 , both sides of which respectively abut against the box body 301 and the connecting piece 102 at one end of the table frame 10 close to the side wing plate 20 .

[0036] It should be noted that, by arranging the insert 40 between the box body 301 and the connecting piece 102, the shaft 3011 is always in contact with the bottom of the first L-shaped groove 1012 and the second L-shaped groove 2011, thereby achieving restrictions in all directions of the table legs 30, the table frame 10 and the side panels 20. It is obvious that in the above installation process, the installer only needs to first insert the insertion end 201 of the side wing panel 20 into the insertion cavity 1011 on the table frame 10, and then make the shaft 3011 on the table leg 30 extend into the corresponding first L-shaped groove 1012 and the second L-shaped groove 2011, and then insert the insert 40 to complete the installation of the table leg 30, the table frame 10 and the side wing panel 20. Compared with the prior art that only eight screws need to be screwed in to connect the table leg 30 and the table frame 10, the embodiment of the present application has the advantage of being able to quickly connect the table legs, table frame and side wing panels without screwing screws.

[0037] Furthermore, to prevent the insert 40 from falling out from between the box body 301 and the connecting piece 102 , when both sides of the insert 40 abut against the table legs 30 and the table frame 10 respectively, the insert 40 is engaged with the tube body 101 .

[0038] Furthermore, in order to realize the snap connection between the insert 40 and the tube body 101, as shown in FIG. Figure 6 As shown, both ends of the insert 40 have a hook portion 401, and each of the hook portions 401 has an inclined surface 4011. Figure 1 and Figure 2 As shown, each of the tube bodies 101 has a through slot 1013 at one end close to the side wing plate 20 , and the through slot 1013 corresponds to the hook portion 401 one by one. The through slot 1013 is connected to the first L-shaped slot 1012 , and the insert 40 is made of plastic.

[0039] It should be noted that when the insert 40 is inserted between the box body 301 and the connecting piece 102, the hook portion 401 extends into the corresponding through groove 1013, and the inclined surface 4011 on the hook portion 401 contacts the groove edge of the through groove 1013. At this time, the hook portion 401 is subjected to force and bends outward at a predetermined angle to facilitate the hook portion 401 to pass through the through groove 1013, and the end face of the hook portion 401 facing away from the inclined surface 4011 abuts against the tube body 101 to prevent the insert 40 from falling out of the through groove 1013.

[0040] Furthermore, in the embodiments of the present application, Figure 4 As shown, the side wing plate 20 is in the shape of a long strip, and one side of the side wing plate 20 is bent 90° to form a bent portion 202, and the two insertion ends 201 are fixedly connected to the side wing plate 20, and the fixed connection method includes but is not limited to welding, and the insertion end 201 is located on the side of the side wing plate 20 having the bent portion 202.

[0041] It should be noted that the distance between the insertion end 201 and the bending portion 202 is equal to the thickness of the connecting piece 102 located at the end of the tube body 101 close to the side wing plate 20. When the insertion end 201 is inserted into the insertion cavity 1011, the connecting piece 102 located at the end of the tube body 101 close to the side wing plate 20 is placed between the insertion end 201 and the bending portion 202.

[0042] Furthermore, in order to facilitate the connection between the side wing panels 20 and the table frame 10 and the external table top, as shown in FIG. Figure 3 and Figure 4 As shown, both ends of the side wing plate 20 and the connecting piece 102 away from the side wing plate 20 each have a connecting hole 203. In the embodiment of the present application, the line connecting the centers of the three connecting holes 203 forms a triangle.

[0043] Furthermore, in order to make the table frame 10, the side panels 20 and the table legs 30 more securely connected, as shown in FIG. Figure 7 As shown, the first L-shaped groove 1012 and the second L-shaped groove 2011 each include a vertical section 10121 , an upward inclined section 10122 and an arc transition section 10123 , and the arc transition section 10123 is located between the vertical section 10121 and the upward inclined section 10122 .

[0044] It should be noted that the shaft 3011 extends from the vertical section 10121. When the installer has not yet inserted the insert 40, the shaft 3011 slightly extends into the inclined upward section 10122 along the arc transition section 10123. When the installer inserts the insert 40, the box body 301 moves away from the side wing plate 20, and makes the bottom of the first L-shaped groove 1012 and the second L-shaped groove 2011 gradually approach the shaft 3011. It can also be understood that the shaft 3011 gradually approaches the bottom of the first L-shaped groove 1012 and the second L-shaped groove 2011 along the inclined upward section 10122, that is, the inclined upward section 10122 is away from one end of the arc transition section 10123. In this process, since the box body 301 has a slight upward movement in the height direction, the box body 301 is further pressed against the side wing plate 20.

[0045] In summary, the table leg and table frame quick assembly structure based on the embodiment of the present application is explained, which provides the table leg and table frame quick assembly structure with advantages such as quick connection of the table legs, table frame and side panels without screwing.

[0046] It is worth mentioning that in the embodiments of the present application, the structure of the table leg and table frame quick assembly is simple, does not involve complex manufacturing processes and expensive materials, and is highly economical. At the same time, for manufacturers, the table leg and table frame quick assembly structure provided by the present application is easy to produce and has low cost, which is more conducive to controlling production costs and further promoting product promotion and use.
