Joint connecting piece of push-and-pull folding table

Abstract

The invention relates to a joint connecting piece of a push-and-pull folding table. The joint connecting piece of the push-and-pull folding table comprises a long joint body, a first rotary block anda second rotary block. A first rotary plate is arranged on the first rotary block. A second rotary plate is arranged on the second rotary block. The first rotary plate and the second rotary plate arerotationally arranged at the two ends of the joint body in the opposite directions respectively. According to the joint connecting piece of the push-and-pull folding table, because a first synchronouslinkage connecting rod and a second synchronous linkage connecting rod are arranged between the first rotary block and the second rotary block, and the first synchronous linkage connecting rod, a sliding pivot, the second synchronous linkage connecting rod are in transmission connection with the first rotary block and the second rotary block, the first rotary block and the second rotary block ofthe joint connecting piece synchronously rotate in the opposite directions, two folding table plates are fixedly connected with the first rotary block and the second rotary block respectively, and finally, when a user folds or unfolds the two folding table plates, the two folding table plates can be folded synchronously, folding actions are smooth, and the actions of pushing in are coherent, the two folding table plates are balanced in folding speed, and the folding speed of the folding table plates is two times that of folding table plates in the prior art.

Description

technical field [0001] The invention relates to the technical field of folding tables, in particular to a joint connecting piece of a push-pull folding table. Background technique [0002] The existing push-pull folding table includes a first support tube, a second support tube, a joint, a first folding table board and a second folding table board, and the first folding table board and the second folding table board are respectively arranged on the first On the support tube and the second support tube, the outer end of the first support tube and the inner end of the second support tube are rotatably connected through a joint, and the joint includes a joint body, a first rotating block and a second rotating block, The first rotating block and the second rotating block are respectively rotatably arranged at both ends of the joint body, and the first rotating block and the second rotating block are respectively slidably arranged in the outer end of the first support tube and th...

Problems solved by technology

Therefore, when the user folds the table board, since there is no linkage connecting part between the first rotating block and the second rotating block, the first and second rotating blocks cannot rotate synchronously, causing the user to turn over and fold the folding table. The folding action of the first folding table and the second folding table is not smooth and coherent, and it is easy to get stuck, and the movement is fast and slow
