In the figure: the sofa frame comprises a sofa frame 1, a bottom frame 11, a top frame 12, a frame 13, supporting columns 14, fixed corner connectors 15, supporting groups 16, vertical supports 161, flat supports 162, support rods 2, support columns 21, a groove frame 3, a backrest frame 4, a fixed cross rod 40, a first clamping head 41, a second clamping head 42 and a third clamping head 43.
Detailed Description
The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
According to the description of fig. 1-4:
a sofa frame with freely adjustable backrest comprises:
the sofa frame 1 comprises an underframe 11, a top frame 12, a frame 13, supporting columns 14, fixed corner connectors 15 and supporting groups 16, wherein the top frame 12 is arranged at the top end of the underframe 11, the frame 13 is arranged in the top frame 12, the supporting columns 14 are respectively arranged between the connecting surfaces of the underframe 11 and the top frame 12, the fixed corner connectors 15 are respectively arranged at four top corners inside the underframe 11, and the supporting groups 16 are respectively arranged inside the underframe 11 and comprise vertical supports 161 and horizontal supports 162 arranged from outside to inside;
the support rods 2 are respectively arranged in the frame 13 and comprise support columns 21 respectively arranged at two ends of the frame;
the groove frames 3 are respectively arranged at the rear part, the left part and the right part of the bottom end of the top frame 12;
the backrest frame 4 is arranged at the top end of the sofa frame 1 and comprises a fixed cross rod 40, a first clamping head 41, a second clamping head 42 and a third clamping head 43 which are arranged from top to bottom.
Because the distance between frame 13 and roof-rack 12 is less than the longest diameter of chuck 41, chuck 41 material is rubber or silica gel, chuck 41 presents the round platform shape, so when back frame 4 inlay card when sofa frame 1 and recess frame 3 top, can prevent that back frame 4 from removing too much downwards, cause to move back frame 4 and sofa frame 1 and recess frame 3 and cause the collision wearing and tearing to because the dop 41 that adopts rubber or silica gel material, can avoid the hole groove between back frame 4 and sofa frame 1 and cradling piece 2 to cause contact wear, influence the utility model discloses a quality to can prevent to move back frame 4 and the hole groove condition of shaking appears to the outside between sofa frame 1 and cradling piece 2.
Because fixed angle sign indicating number 15 presents triangle-shaped to the rigidity of 1 four apex angles of sofa frame has been increased, the utility model discloses overall structure's fastness has been strengthened.
Because the inner width of groove frame 3 equals the diameter of dop two 42, dop two 42 are cylindrical, dop two 42 materials are rubber or silica gel, the inner width of groove frame 3 is greater than the longest diameter of dop three 43, so make back frame 4 bottom dop three 43 can inlay card in groove frame 3, and through dop two 42, can prevent back frame 4 inlay card behind sofa frame 1 and groove frame 3, the condition of outwards shaking appears, also through the inlay card of dop one 41, dop two 42 and dop three 43, make back frame 4 whole can be with regard to user's user demand, shift the inlay card position of back frame 4 fast, and after the inlay card, firm in connection.
Because the cradling piece 2 presents the Y font, so through cradling piece 2, greatly increased the utility model discloses horizontal rigidity has guaranteed the utility model discloses the fastness of structure.
And because erect the establishment of support 161 and flat support 162, greatly increased the utility model discloses horizontal rigidity has guaranteed the utility model discloses the fastness of structure.
And because support column 14, greatly increased the utility model discloses fore-and-aft rigidity has guaranteed the utility model discloses the fastness of structure.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments.
