The specific embodiment
See also shown in the accompanying drawing 2,3, connecting structure improvement between the seat portion of office chair, back of the body bar, mainly be meant the seat portion 1 of office chair, the connecting structure of 2 on bar of the back of the body, wherein: seat portion 1, can be and mould goods, its rear side has a perforating 11, and sidewall has one locking part within the perforating 11, as can burying a nut 12 underground, and the lateral wall of perforating 11 is established a horizontal perforation 13; Back of the body bar 2 can be and moulds goods, and its section peripheral shape is the poroid of corresponding perforating 11, makes it correspondence wear perforating 11, and back of the body bar 2 is provided with long straight hole 21 in the bottom appropriate location, and wears long straight hole 21 right positions, back in perforating 11 places.
See also shown in the accompanying drawing 4, make back of the body bar 2 penetrate the perforating 11 of seat portion 1 during assembling earlier, and after borrowing a bolt 3 ecto-entads to pass horizontal perforation 13, long straight hole 21 in regular turn, and the lock spiral shell can be assembled in lock-combining part (nut 12) and finishes, and borrow bolt 3 to screw, add perforating 11,2 on bar of the back of the body wear the tight system of group can be firm, when adjusting the height of back of the body bar 2 in addition, then earlier by unscrewing bolt 3, after making back of the body bar 2 accent move to suitable height, screw bolt 3 location again, that is transfer and move the height that back of the body bar 2 can be adjusted in the position of loose bolt 3 in long straight hole 21, very easy.
Because seat portion 1,2 assemblings of back of the body bar are only got final product by bolt 3 lock spiral shells by wearing the group back, and
Also be easy to transfer the height that moves back of the body bar 2, thus must aforementioned metal system commonly used base, therefore, not only can omit the cost of this metal system base and pay, and it assembles and become very easy, so can promote its product competitiveness greatly.
In addition, the top of back of the body bar 2 can have a horizontal axostylus axostyle 22, and the rear of backboard 4 then correspondence has buckle ear 41, if buckle ear 41 1 tools, it is a strip, if two tools above (as shown in Figure 2) then are the corresponding two side ends that is divided into horizontal axostylus axostyle 22, horizontal axostylus axostyle 22 are buckled in the buckle ear 41 can finish assembling, also very easy, without screw, and backboard 4 can supply switching (as shown in Figure 4), can transfer with occupant's health and move.Carry on the back the outside, top of bar 2 again and can establish leader 23 again.
