The specific embodiment
Below in conjunction with accompanying drawing, the present invention is illustrated: with reference to accompanying drawing 1 and accompanying drawing 2, a kind of convenient chair of adjusting backrest height, be comprised of seat 1, left front leg 21, RAT 22, left back leg 23, right rear leg 24 and backrest 3.Seat 1 is horizontally disposed.Left front leg 21, RAT 22, left back leg 23 and right rear leg 24 are fixed on respectively the place, four angles of seat 1, and all are positioned at seat 1 below, play a supportive role.Backrest 3 is positioned at the back edge top of seat 1.Backrest 3 is equal to or slightly greater than 90 ° with the angle of seat board 1.
A kind of convenient chair of adjusting backrest height of the present invention is to adjust like this backrest height:
Left branching rod 32 has lateral penetration hole, three of upper, middle and lower from top to bottom, the right pole 33 of identical height and position, three lateral penetration holes is arranged also from top to bottom, and these six lateral penetration hole sizes are identical.The upper horizontal through hole of left branching rod 32 is same high and coaxial with the upper horizontal through hole of right pole 33, the middle lateral penetration hole of left branching rod 32 is with the middle lateral penetration hole of right pole 33 with high and coaxial, and the lower horizontal through hole of left branching rod 32 is same high and coaxial with the lower horizontal through hole of right pole 33.
at first portable plate 31 is enclosed within on left branching rod 32 and right pole 33 from top to bottom, be that left branching rod 32 and right pole 33 are inserted into respectively left vertical tube 313 and right vertical tube 314, and make lower transverse tubule 312 endoporus coaxial with the lower horizontal through hole of left branching rod 32 and right pole 33, then backstay 34 is inserted from left to right the lateral penetration hole of left vertical tube 313, the lower horizontal through hole of left branching rod 32, lower transverse tubule 312 endoporus, the lateral penetration hole of right vertical tube 314 and the lower horizontal through hole of right pole 33, portable plate 31 was fixed and was in extreme lower position this moment, be that backrest 3 is in extreme lower position, this moment, the total height of this chair was the shortest state.
in order to promote the backrest height of this chair, total height at above-mentioned this chair is on the basis of the shortest state, backstay 34 is pulled out fully, portable plate 31 is improved and makes lower transverse tubule 312 endoporus coaxial with the middle lateral penetration hole of left branching rod 32 and right pole 33, then backstay 34 is inserted from left to right the lateral penetration hole of left vertical tube 313, the middle lateral penetration hole of left branching rod 32, lower transverse tubule 312 endoporus, the middle lateral penetration hole of the lateral penetration hole of right vertical tube 314 and right pole 33, this moment portable plate 31 height and position that mediates, it is backrest 3 height and position that mediates, this moment, the total height of this chair was intermediateness.
The backrest height of this chair can also be toward raising, backstay 34 is pulled out fully, continuation up improves portable plate 31, make lower transverse tubule 312 endoporus coaxial with the upper horizontal through hole of left branching rod 32 and right pole 33, then backstay 34 is inserted from left to right the lateral penetration hole of left vertical tube 313, upper horizontal through hole, lower transverse tubule 312 endoporus, the lateral penetration hole of right vertical tube 314 and the upper horizontal through hole of right pole 33 of left branching rod 32, this moment, portable plate 31 was in extreme higher position, be that backrest 3 is in extreme higher position, this moment, the total height of this chair was high state.
If the backrest height of this chair will be adjusted to low level from a high position, be on the basis of high state as the total height at above-mentioned this chair, after backstay 34 is pulled out fully, portable plate 31 is dropped to the gear that needs, then with backstay 34 positioning instants, can realize that backrest height is adjusted to low level from a high position.
