Description
The technical field is as follows:
the utility model relates to a seat technical field, in particular to iron seat structure.
Background art:
the folding chair is a chair with portable and stackable functions, is convenient to move and saves space, has the defects of relatively complex structure, complex operation, poor structural stability, poor safety performance and the like of the existing folding chair, and has large volume, thicker thickness and inconvenient moving and storage after being folded.
The utility model has the following contents:
the utility model provides an iron seat structure has solved poor stability among the prior art, folding back bulky problem.
The technical solution of the utility model is as follows: the utility model provides an iron seat structure, is including preceding leg frame and back leg frame, it has the seat board to articulate on preceding leg frame and the back leg frame, preceding leg frame is the type of falling, back leg frame is vertical I shape, department and back leg frame correspond between the both sides upper end all articulated connecting plate group that is connected with in the middle of the preceding leg frame both sides, back leg frame upper end cover is equipped with support sleeve, support sleeve is including the pipe box of plug bush on the back leg frame, the shaping of corresponding preceding leg frame one side in the pipe box upper end has the ascending recess of slope, the shaping of preceding leg frame one side has convex card before the pipe box is kept away from.
Preferably, the seat plate is hinged below the connecting plate group.
Preferably, the bottom parts of the front leg frame and the rear leg frame are inserted with anti-slip sleeves.
Preferably, two sides of the lower end of the front leg frame are fixedly connected with supporting cross rods. The support cross rod improves the structural strength of the front leg frame.
Preferably, the upper end of the front leg frame is formed with an arc section with an opening facing to a side far away from the rear leg frame, and the upper end of the front leg frame is fixed with a backrest, and the backrest is concave to a side close to the rear leg frame. The arc segment and back design improves seat comfort.
Preferably, the opening of the arc-shaped card is forwards far away from one side of the front leg frame, the inner diameter of the arc-shaped card is consistent with the outer diameters of two sides of the front leg frame, the arc-shaped card is elastic, and a limiting convex strip is formed on the inner side of the opening end of the arc-shaped card. When a plurality of seats are folded and arranged, the front leg of the other seat can be erected and embedded in the circular arc-shaped clamping sheet of the supporting sleeve, so that the occupied space is small, and the seats are convenient to arrange, move and store.
The beneficial effects of the utility model reside in that: the utility model discloses a seat simple structure, preceding, back leg frame are opened the back, and preceding leg frame leans on in the recess on the support sleeve, easy operation, and structural stability is strong, and preceding, back leg frame are folding, can set up the preceding leg of another seat in support sleeve's convex card, and occupation space is little, conveniently arranges and moves and deposit.
Description of the drawings:
fig. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic structural view after the utility model is folded;
fig. 3 is a schematic structural diagram of the middle support sleeve 4 of the present invention.
