Description
Technical field
The present invention relates to the dining chair that a kind of children use.
Background technology
Dining chair of the prior art, a kind of dining chair, comprise first support, second support that rotates and be connected with first support, be arranged at the locking mechanism between first support and second support, when locking mechanism was in the release duty, described first support, second support can rotate mutually, when locking mechanism is in the locking duty, the position relative fixed between described first support, second support.But two supports of prior art are plastic materials what be rotationally connected the joint employing, so mechanical strength is poor, do not improve intensity potential safety hazard is then arranged, be to strengthen two supports by thickening to improve intensity at present at the volume of the joint that is rotationally connected, then cause whole connection arthritic volume to increase, relatively heavier.
Summary of the invention
The object of the invention provides a kind of dining chair, makes the arthritic volume that is rotationally connected of dining chair little, the intensity height.
For achieving the above object, the technical solution used in the present invention is: a kind of dining chair, comprise the dining chair frame, be arranged at the seat on the described dining chair frame, described dining chair frame comprises first support and second support that the upper end rotates and connects, described first support comprises first rack body, be fixedly connected on first metal arm of the upper end of described first rack body, described second support comprises second rack body, be fixedly connected on second metal arm of the upper end of described second rack body, the upper end of described first metal arm, the upper end of second metal arm is by the rotating shaft connection that rotates.
Described first metal arm is positioned at the inboard of described second metal arm, the upper end of described first metal arm extends to form the first conflict sheet laterally, described first support has relative two duties of opening and drawing in relatively with second support, when described first support and second support were in relative open duty, the upper end of the described first conflict sheet and second metal arm offseted above described rotating shaft; When described first support was in the duty of relative gathering with second support, the upper end of the described first conflict sheet and second metal arm was separated.
The upper end of described second metal arm extends to form the second conflict sheet to the inside, and when described first support and second support were in relative open state, the described second conflict sheet and the first conflict sheet offseted; When described first support was in the state of relative gathering with second support, the described first conflict sheet and the second conflict sheet were separated.
The described first conflict sheet extends outwardly into the outside of second metal arm from the upper end of first metal arm, the lateral surface that is pasting described second metal arm after the bending again extends to form first barrier sheet; The described second conflict sheet extends inward into the inboard of first metal arm from the upper end of second metal arm, the medial surface place of pasting described first metal arm after the bending again extends to form second barrier sheet, make described first barrier sheet retaining in the outside of second metal arm, described second barrier sheet retaining is in the inboard of first metal arm.
Has groove on described second barrier sheet to side depression, has also reinforcement on described first metal arm towards this side projection, when first support and second support are in relative open duty, described reinforcement is inserted in the described groove, when described first support was in the duty of relative gathering with second support, described reinforcement broke away from groove.
Be provided with locking mechanism between described first support and second support, described locking mechanism comprises first locked groove, second locked groove that are arranged on described first support, is arranged at the lock dog on described second support, when described locking mechanism was in the lock state, described lock dog was inserted in described first locked groove or second locked groove; When described locking mechanism was in released state, described lock dog broke away from first locked groove and second locked groove.
Described locking mechanism also comprises and the described lock dog all-in-one-piece unlock button that is fixedly connected, and is provided with between described unlock button and described second support to be used to elastic component that unlock button is resetted.
Because the technique scheme utilization, the present invention compared with prior art has following advantage: because the present invention has adopted described first metal arm, second metal arm, thus improved dining chair in the intensity that connects joint, and reduced to connect the volume in joint.
