Portable folding chair

Abstract

The invention discloses a portable folding chair. The portable folding chair comprises a seat, a pillar and chair legs. When the portable folding seat is in a folded state, seat side plates are folded to form a cylindrical form, and are fixed by a locking mechanism, and the pillar and the chair legs are contracted in the first segment of the pillar, so the pillar and the chair legs are integrally stored in the back groove of the seat. When the portable folding chair is in use, the seat side plates are expanded, so the area of a force bearing surface is increased; the upper portion of the top joint of the pillar is fixed in a threaded groove in the back side of the seat through a thread, and the lower portion of the top joint of the pillar is connected with the first segment of the pillar; every segment of the pillar is stretched and rotated to adjust the height of the portable folding chair, and every segment of the pillar is provided with a rotary fixing structure; and the bottom joint of the pillar is connected with the chair legs, and the back side of every chair leg is provided with a reinforcement. The telescoping structure design of every segment of the pillar allows the height of the seat to be freely adjusted; the reinforcements at the back sides of the chair legs increase the working strength of the seat; and the portable folding chair adopting folding combination of all parts has the advantages of full saving of the occupied space in the carrying process, simplicity in installation, and high applicability.

Description

technical field [0001] The invention relates to a portable folding chair. [0002] technical background [0003] During outdoor activities and queuing, it is often impossible to rest due to vacant seats. Ordinary folding chairs are not easy to carry due to factors such as size and complex structure. At this time, a portable folding chair that is light in weight and occupies a small space can play an important role. Most common folding chairs have complex skeleton structures and complicated installation steps, which cause inconvenience in use, and folding chairs are too complicated, easily deformed and damaged after repeated assembly and disassembly, and their service life is sharply reduced. In addition, folding chairs with a simple structure are generally larger in size and heavier in weight, and tend to occupy a larger space, which is inconvenient to carry. Therefore, it is of great significance to design a portable folding chair with sufficient folding and simple structur...
