Problems solved by technology

[0002] A folding table in the prior art usually uses support hinges to support the leg tubes, and realizes the positioning connection between the leg tubes and the desktop board. This support hinge structure often produces shear points during use, and there is a safety hazard Hidden dangers; there are also some complex four-bar linkages to achieve positioning and connection, but this mechanism is often realized by using two desktop boards folded in half. This structure often causes a depression in the middle of the desktop, which not only affects the appearance, but also Use; there are still some using sliding mechanism or clamping mechanism to realize the positioning support of the foot tube, but the structure is often more complicated, the operation is more cumbersome, and the manufacturing cost is higher

Abstract

The invention discloses a folding picnic table. A table top plate is fixedly arranged on a framework which is formed by table frame pipes and cross beam pipes; a long foot pipe and the table frame pipes are hinged; positioning pieces are fixedly connected to the tale frame pipes; a short foot pipe and the positioning pieces are hinged; the table frame pipe, the long foot pipe and an obliquely supporting pipe and the table frame pipe, the short foot pipe and the obliquely supporting pipe are formed into two symmetrically arranged triangular mechanisms to support the table top plate to achieve unfolding and folding of the folding picnic table. The folding picnic table has the advantages of being simple in structure, convenient to operate and suitable for utilization in indoor, courtyard, camping and the like occasions.

Description

technical field [0001] The present invention relates to a table, in particular to a folding picnic table. Background technique [0002] A folding table in the prior art usually uses support hinges to support the leg tubes, and realizes the positioning connection between the leg tubes and the desktop board. This support hinge structure often produces shear points during use, and there is a safety hazard Hidden dangers; there are also some complex four-bar linkages to achieve positioning and connection, but this mechanism is often realized by using two desktop boards folded in half. This structure often causes a depression in the middle of the desktop, which not only affects the appearance, but also use; there are also some that use a sliding mechanism or a snap-in mechanism to realize the positioning support of the foot tube, but this structure is often more complicated, the operation is more cumbersome, and the manufacturing cost is higher. Contents of the invention [0...
