In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.

The specific embodiment of the utility model is as follows:

example (b): as shown in fig. 1-6, the present invention provides a table and chair support connection assembly, which is an integral part of an integrated table and chair, and will be described in detail below. The integrated table and chair comprises a table board 1 and a seat 2, and the table board 1 and the seat 2 are connected through the table and chair supporting and connecting assembly.

As shown in fig. 1, the table and chair support connection assembly includes a connection member 3, a table support rod 11, a seat connection rod 12 and a connection rod 23. Wherein, the desk support rod 11 is vertically disposed on the bottom end surface of the desk 1, and the seat connecting rod 12 is connected with the bottom of the seat 2 and extends along the horizontal direction. Be provided with first connector 6 and second connector 7 on the connecting piece 3, first connector 6 extends and can dismantle with table bracing piece 11 along vertical direction and be connected, and second connector 7 extends and can be connected with seat connecting rod 12 along the horizontal direction.

Specifically, as shown in fig. 3 and 4, the connecting member 3 in the present embodiment includes a base 4 and a connecting seat 5, wherein the base 4 is an arc tube bent at the middle portion thereof, and the ends at the two ends of the arc tube respectively form the first connecting head 6 and the second connecting head 7. The first connector 6 is provided with a first slot 8 for inserting a desk support rod 11, and the second connector 7 is provided with a second slot 9 for inserting a seat connecting rod 12. And the sliding insertion of the desk support rod 11 and the seat connecting rod 12 is facilitated. Referring to fig. 6, the inner walls of the first slot 8 and the second slot 9 are provided with a plurality of protruding strips 10. When the desk board support bar 11 is inserted into the first slot 8, the outer wall of the desk board support bar 11 abuts against the raised strip 10 on the inner wall of the first slot 8. When the seat connecting rod 12 is inserted into the second slot 9, the outer wall of the seat connecting rod 12 abuts against the convex strip 10 on the inner wall of the second slot 9. Through sand grip 10, reduce the area of contact on the outer wall of table bracing piece 11 and the 8 inner walls of first slot, also reduce the area of contact on the outer wall of seat connecting rod 12 and the 9 inner walls of second slot to frictional force has been reduced, thereby be convenient for the slip grafting of table bracing piece 11 and seat connecting rod 12.

Meanwhile, as shown in fig. 6, the groove walls of the first slot 8 and the second slot 9 are provided with avoidance grooves 24 at the groove openings, and the desk support rod 11 and the seat connecting rod 12 are provided with riveting nuts. When the table board supporting rod 11 is inserted into the first slot 8, the riveting nut on the table board supporting rod 11 is positioned in the avoiding slot 24 in the first slot 8, and the first connecting head 6 is connected with the riveting nut on the table board supporting rod 11 through a screw.

Similarly, when the seat connecting rod 12 is inserted into the second slot 9, the rivet nut on the seat connecting rod 12 is located in the avoiding slot 24 in the second slot 9, and the second connector 7 is connected with the rivet nut on the seat connecting rod 12 through a screw. When the connection and the matching are carried out, the desk plate supporting rod 11 is further fixed through the screw, the desk plate supporting rod 11 is prevented from sliding out of the first slot 8, and the seat connecting rod 12 is also prevented from sliding out of the second slot 9. The connection of the table board support rod 11, the bottom plate connecting rod and the connecting piece 3 is more stable, and the stability of the structure is improved. If directly open the screw hole on table bracing piece 11, bottom plate connecting rod 12, the problem that table bracing piece 11, bottom plate connecting rod 12 pole wall are too thin appears unavoidably, and long-time back, when the screw hole is worn and torn, can directly change the riveting nut and need not change table bracing piece 11, bottom plate connecting rod 12.

In this scheme, base 4 and connecting seat 5 can be dismantled and be connected, as shown in fig. 5, is provided with first recess 13 on base 4, is provided with second recess 14 on connecting seat 5. When the base 4 is connected with the connecting seat 5, the first groove 13 and the second groove 14 are matched to form a through hole 15. The connecting rod 23 passes through the through hole 15, and both ends of the connecting rod 23 are provided with supporting wheels 22. The supporting wheels 22 are arranged at the two ends of the connecting rod 23, so that the supporting area of the bottom is increased, and the movement of the equipment is facilitated.

Meanwhile, the base 4 is provided with a positioning slot 16, and the connecting rod 23 is provided with a positioning plate 17. During assembly, the connecting base 5 is first removed. The positioning plate 17 is then placed in the positioning slot 16, and the rod wall of the connecting rod 23 is attached to the inner wall of the first groove 13. The positioning plate 17 is connected with the bottom of the positioning groove 16 through a screw. Finally, the connecting seat 5 is covered and fixed in an involutory way. So that the connecting rod 23 does not move along the length direction thereof relative to the base 4, resulting in the shift of the center of gravity of the whole.

And further, when the positioning plate 17 is placed in the positioning groove 16, the supporting wheels 22 at the left and right ends of the connecting rod 23 are equally spaced from the side walls of the adjacent bases 4. Because the positioning groove 16 is arranged on the base 4, the positioning plate 17 is arranged in the positioning groove 16 and then fixed, the distance between the left side and the right side of the connecting rod 23 and the base 4 does not need to be measured during manual installation, and the positioning can be completed as long as the positioning plate 17 is arranged in the positioning groove 16. And when the base 4 is connected with the connecting seat 5, the connecting seat 5 covers the end surface of one side of the arc-shaped pipe, which protrudes outwards.

In addition, referring to fig. 5 and 6, in the present embodiment, two side walls of the connecting member 3, through which the through hole 15 passes, are provided with the foot pedal 18. Specifically, bosses 19 are arranged on two side walls of the connecting piece 3, which are penetrated with the through holes 15. And the bottom of the foot board 18 is provided with a supporting block 20, and the supporting block 20 is provided with a mounting groove 21. When the boss 19 is inserted into the mounting groove 21, the support block 20 is connected to the boss 19 by a screw. The bottom of the pedal 18 is supported by the matching of the supporting block 20 of the pedal 18 and the boss 19 on the connecting piece 3, so that the bottom of the pedal 18 is prevented from being hung in the air and being easily broken. And the supporting block 20 is connected with the boss 19 through a screw, so that the pedal plate 18 is prevented from being separated from the boss 19, and the structure is more stable. And the bottom end surface of the foot rest 18 is also abutted against the connecting rod 23. The connecting rod 23 is used for supporting the pedal 18, so that the pedal has two purposes, and the bottom of the pedal 18 is supported.

The present invention and its embodiments have been described above schematically, without limitation, and what is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if the person skilled in the art receives the teaching, without departing from the spirit of the utility model, the person skilled in the art shall not inventively design the similar structural modes and embodiments to the technical solution, but shall fall within the scope of the utility model.
