As shown in fig. 1 to 3, an embodiment of the present application provides a lower frame structure for a table body, including: the device comprises a cross beam 1 and a connecting joint 6 arranged at the end part of the cross beam 1; wherein the content of the first and second substances,

the end part of the beam 1 is provided with a connecting groove 3, and the upper part and the lower part of the connecting groove 3 are both provided with connecting parts 2;

one side of the connecting joint 6 close to the cross beam 1 is provided with a connecting surface 7, the connecting surface 7 is provided with a convex butt joint part 4, and the butt joint part 4 is inserted in the connecting groove 3; the one side that connector 6 pressed close to connecting portion 2 is seted up the first connecting hole 5 that corresponds with connecting portion 2, and first connecting hole 5 passes through connecting screw fixed connection with connecting portion 2.

In this embodiment, the lower frame structure mainly includes the connection joints 6 and the cross beams 1, and the number of the connection joints 6 and the number of the cross beams 1 can be determined according to the use requirement. For example, when a rectangular lower frame structure is required, at least four connecting joints 6 need to be arranged, four corresponding connecting joints 1 need to be arranged, and two ends of each beam 1 are fixedly connected with the corresponding connecting joints 6, so that a frame-shaped lower frame structure is formed. For being connected of crossbeam 1 and attach fitting 6, a spread groove 3 has been seted up at the tip of crossbeam 1 to one side that is close to crossbeam 1 with attach fitting 6 sets up to be connected face 7, and all is provided with the butt joint portion 4 that corresponds with spread groove 3 on crossbeam 1 on each is connected face 7. When the connecting device is installed, the butt joint part 4 of the connecting joint 6 is inserted into the connecting groove 3 of the cross beam 1, the connecting surface 7 of the connecting joint 6 is also attached to the end surface of the cross beam 1, and the connecting joint 6 and the cross beam 1 can be assembled at the moment. The connecting groove 3 is also provided with the connecting part 2, and the connecting joint 6 is also provided with a connecting hole corresponding to the connecting part 2. After the connecting joint 6 and the cross beam 1 are assembled, connecting screws can be screwed into the connecting holes and the connecting parts 2, so that the connecting joint 6 is stably fixed at the end part of the cross beam 1. In order to further improve the connection strength of the connection joint 6 and the beam 1, the connection part 2 is arranged at the upper part and the lower part of the connection groove 3, so that the upper part and the lower part of the connection joint 6 can be stably supported, and the stability of the whole structure is improved.

This embodiment only need unscrew the connecting screw from crossbeam 1 and attach fitting 6 when dismantling, then take off attach fitting 6 from crossbeam 1 can, the dismouting is more convenient. And because the butt joint part 4 of the connecting joint 6 is inserted in the connecting groove 3, the cross beam 1 has a stress point on the connecting joint 6, and the bearing capacity of the frame body structure can be improved.

As shown in fig. 1 to 3, the butt joint portion 4 includes a first band 43, a second band 41, and a third band 42;

the connecting groove 3 comprises a first groove body 31, a second groove body 33 and a third groove body 32, and a first insertion strip 43, a second insertion strip 41 and a third insertion strip 42 are respectively embedded in the first groove body 31, the second groove body 33 and the third groove body 32.

Specifically, in order to further improve the bearing capacity of the connecting joint 6 on the cross beam 1, the abutting portion 4 is composed of three insertion strips, namely a first insertion strip 43, a second insertion strip 41 and a third insertion strip 42, and the connecting groove 3 is provided with a first groove 31, a second groove 33 and a third groove 32 correspondingly. Furthermore, the first fillet 43, the second fillet 41 and the third fillet 42 are respectively positioned in three different directions, so that the force application in three directions of the cross beam 1 can be borne, and the bearing capacity is improved.

For the accuracy that improves attach fitting 6 and crossbeam 1 butt joint position, connecting portion 2 sets up to three, and three connecting portion 2 are triangular distribution. The first, second and

third grooves

31, 33, 32 are separated by three connecting portions 2. The connecting part 2 can be matched with a connecting screw to realize the fixed connection of the connecting joint 6 and the cross beam 1, and can also play a role in guiding and limiting the butt joint of the first insertion strip 43, the second insertion strip 41 and the third insertion strip 42 in the connecting groove 3, and can also avoid the transverse movement of the connecting joint 6.

As shown in fig. 1 to 3, the first band 43 is provided in a flat plate shape at an upper portion of the connection surface 7, the second band 41 is provided in an L shape at one of corner portions of the connection surface 7, the third band 42 is provided at the other corner portion of the connection surface 7, the third band 42 includes a vertical portion and an arc portion, and the arc portion is provided at a lower end of the vertical portion;

the lower end of the cross beam 1 is set to be an arc-shaped surface, and the edge profiles of the first groove body 31, the second groove body 33 and the third groove body 32 are respectively matched with the shapes of the first insertion strip 43, the second insertion strip 41 and the third insertion strip 42, so that the attaching degree of the connecting joint 6 and the cross beam 1 is improved, the structure is more compact, and the bearing capacity is also improved.

As shown in fig. 1 to 3, the connecting surfaces 7 of the connecting joint 6 are disposed on two adjacent surfaces, and a cross beam 1 is fixedly disposed on each connecting surface 7, that is, the cross beams 1 are perpendicular to the two cross beams 1 of the connecting joint 6.

As shown in fig. 1 to 3, the upper end of the connection joint 6 is open, the first connection hole 5 is communicated with the upper end region of the connection joint 6, and the lower end of the connection joint 6 is opened with the second connection hole 8, thereby facilitating the fixing of the connection joint 6 on a lower support, such as a pillar. The outer contour of the connecting surface 7 is the same as that of the end of the cross beam 1, so that the surface of the frame body structure is smoother.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
