Abstract
The utility model discloses a kind of chair frame, to comprise being symmetricly set on below seat surface on two side positions with the support play fixed supporting role, described support is for having forward and backward pole (1) and being connected in the inverted U support body of the connecting rod (3) between described forward and backward pole top, wherein, described forward and backward pole is also connected with pull bar (2) between middle section position.Compared to existing technology, the utility model is by arranging pull bar, make the stressed mutual transmission of forward and backward pole, so forward and backward rod receiver is average, that can reduce single pole to a great extent bears pressure, thus greatly can increase overall firmness, Stability Analysis of Structures is reliable, safe and practical.
Description
Technical field
The utility model relates to field of furniture, particularly relates to a kind of chair frame.
Background technology
Chair frame major part of the prior art is inverted U, in order on two side positions being arranged on below seat surface of symmetry to play the effect of fixed support, and arm-rest frame is normally fixed together with the top structure of the chair back and chair frame, with regard to stability, before and after such chair frame, stressed property is poor, insecure, especially people sits and it to like leaning against usually on the chair back and to tilt two chair pin above, now, rocks before and after rear two chair pin land, chair frame just easily gets loose and falls apart, very dangerous.
Summary of the invention
In view of this, technical problem to be solved in the utility model is: provide the chair frame that a kind of Stability Analysis of Structures is reliable, safe and practical.
In order to achieve the above object, the utility model adopts following technical scheme to realize:
A kind of chair frame, to comprise being symmetricly set on below seat surface on two side positions with the support play fixed supporting role, described support is the inverted U support body having forward and backward pole and be connected in the connecting rod between described forward and backward pole top, and wherein, described forward and backward pole is also connected with pull bar between middle section position.
As shown from the above technical solution, the beneficial effects of the utility model are:
Compared to existing technology, the utility model is by arranging pull bar, make the stressed mutual transmission of forward and backward pole, so forward and backward rod receiver is average, that can reduce single pole to a great extent bears pressure, thus greatly can increase overall firmness, Stability Analysis of Structures is reliable, safe and practical.
