Detailed Description

In order to make the utility model realize that technical means, creation characteristics, achievement purpose and effect are clearer and easily understand, it is right to combine below the figure and the detailed implementation mode the utility model discloses do further explanation:

referring to fig. 1, for the utility model discloses a portable arm-chair, including base 1, arrange in base 1 top and end-to-end articulated backup plate 2, bedplate 3, front strut 4, at least two middle extension board 5 and back support 6 in order. The front support plate 4, the middle support plate 5 and the rear support plate 6 are arranged at the bottom of the seat plate 3 in a zigzag shape, and the bottom of the seat plate 3 is provided with a positioning groove 31 (refer to fig. 4) embedded with an upper end hinge 51 of the middle support plate 5. The backup plate 2 is detachably connected to the rear support plate 6 through a locking piece 7, so that the backup plate 2 is perpendicular to the seat plate 3 and limits the rotation of the rear support plate 6.

Referring to fig. 2, the base 1 is provided with a positioning stud 11 screwed to the lower end hinge 52 of the intermediate bracket 5. During installation, the base 1 can be installed below the middle support plate 5 by simply screwing the positioning stud 11, so that abrasion of the hinge 52 at the lower end of the middle support plate 5 is reduced.

Referring to fig. 3, the locking member 7 includes a support plate 71 disposed on the backup plate 2, a T-shaped groove 72 formed in a plate surface of the support plate 71, and a flexible T-shaped strip 73 disposed on the rear support plate 6, an end surface of the T-shaped strip 73 is provided with a deformation groove 74 and guide surfaces 75 disposed at both ends of the receiving groove 21, and the receiving groove 21 penetrates through the T-shaped strip 73 in the length direction. The plate surface of the pallet 71 is provided with a holding groove 76. The T-shaped strip 73 is engaged with the T-shaped groove 72 along the guide surface 75 and is slidably disengaged along the opening of the T-shaped groove 72. The T-shaped strip 73 and the supporting plate 71 with the T-shaped groove 72 form a detachable structure, so that the rear supporting plate 6 and the supporting plate 71 can be conveniently detached.

Referring to fig. 4, when the chair needs to be folded, the free end of the back board 2 can be overturned and overlapped on the seat board 3, the end of the front board 4 can be overturned and overlapped on the bottom surface of the seat board 3, and the two ends of the middle board 5 can be overturned and overlapped between the front board 4 and the rear board 6. When overlapped, the plate surfaces of the backup plate 2, the seat plate 3, the front support plate 4, the middle support plates 5 and the rear support plate 6 are parallel to each other, and the outer end surfaces are flush.
