folding support frame for table

Abstract

The invention relates to a foldable support frame for a table, which includes: an upper plate frame, an end face connecting part and a foot part; wherein, the upper end of the foot part is formed along the length direction with a guide groove that can be inserted into a movable clamp, and the movable clamp and the folding Compression springs are connected between the leaf pins; the body of the end face connection part is formed with a through part, the upper end of the leg part is inserted into the through part and rotatably combined by the hinge pin, a connecting groove is formed on the top of the body, and a curved guide part is formed on the side of the body ; When the leg part is rotated to expand the leg part, the movable clip will be guided by the curved guide part, and move backward under the elastic force of the compression spring to combine with the connecting groove. The folding structure of the leg part of the present invention is relatively simple and easy to manufacture. When the leg part is unfolded, even if an external force acts on the leg part, the movable clip will not break away from the connecting groove, so it can be used stably.

Description

technical field [0001] The invention relates to a foldable support frame for a table, in particular to a foldable support frame for a table with foldable structural legs supported under the upper board of the table. Background technique [0002] In general, in schools, colleges, and corporate meeting rooms, churches, and other places for public use, for the convenience of storage, a combination table or a folding table is mostly used. [0003] The above combined table or foldable table has table legs supporting the upper plate, and the legs are foldably installed on the supporting frame for fixing the upper plate. [0004] The above-mentioned folding table or combined table must be able to fold the legs and store them inside the support frame, and ensure that the folded legs will not be exposed to the outside after folding, so that they can be stacked and stored stably. [0005] As an example of the above-mentioned folding desk, the present applicant previously applied for ...

AI Technical Summary

Problems solved by technology

[0007] But, above-mentioned utility model, leg part 20 is fixed by folding part 40, and folding part 40 is made of fixing part 41 that fixes leg part 20 and the holding part 42 that grasps by hand, and one side of fixing part 41 is fixed with upper plate supporting part 10, The other side is fixed to the leg member 20 so that one side of the fixing member 41 can be folded, and the outer surface is formed with a fixing hole 41a passing through the fixing piece 2 and fixing it and an elastic spring 41b that ensures that the fixing member 41 will not fold , therefore, its structure is complex and its manufacturing cost is high

[0008] On the other hand, one side of the fixing part 41 of the above-mentioned utility model has a foldable structure, if a little external force is applied, the fixing part 41 will be folded, therefore, the leg part 20 is very easy to fold and cannot be used safely.

[0009] In addition, when used for a long time, the leg parts 20 will shake due to looseness, reducing the stability
