Description
Technical field
This utility model relates to back connecting device technical field, the connecting device of especially a kind of back.
Background technology
Chair in the market is divided into following three kinds, and one is that its backrest is directly anchored in connecting rod, and connecting rod and chassis are fixing to be connected, when consumer's use its backrest cannot fitted with body curve, be not human oriented design, gradually by market.Another kind is to arrange bindiny mechanism between connecting rod and backrest, by mechanical type connected mode, connects such as rotating shaft etc., and this mode more fitted with body curve uses comfortable, but relatively costly, and human body is top goes later adjustment automatically not soft, and price is also high.Also having a kind of device being to fix in connecting rod an installation position, then backrest is directly inserted in the connected mode in device, this connected mode is safe and reliable not.So how to make a kind of simple, firm, safety, comfortable and cheap back attachment structure easy to adjust, the problem that inventor to solve just.
Utility model content
This utility model solves the problem that traditional mechanical formula backrest connected mode cost is high, comfort level is low, it is provided that a kind of can according to the automatically soft adjustment backrest form of body curve, the connecting device of simple and cheap back easy for installation.
The connecting device of a kind of back, including fixing the connecting rod being connected with Chair underpan；Described connecting rod is fixed with the fixing seat no less than；Described fixing seat is provided with the first location structure, and fixing seat is provided with the first position, hole of the fitting that is fixedly connected, and fixing seat is fixedly connected fitting by threaded screw and nut assembly；One end of described fixing connector is fixing with back to be connected, and the other end is provided with the second location structure and the second position, hole connected for screw thread or securing member.
Further, described fixing connector be metal derby with gum elastic in conjunction with goods.
Further, described fixing connector is at 2 with backrest link and threadeds, outer likeness in form arch；One end that fixing connector is connected with fixing seat is embedded with metal derby, and metal derby is provided with the second location structure and the second position, hole connected for screw thread or securing member.
Compared with prior art, this utility model has the advantages that connector configuration design becomes " bow " shape structure to be connected with backrest, and " bow " shape structure can adjust the elasticity of connector, so as to namely excessively not soft, only in firm, can according to actually required elastic adjustment；During installation, the metal derby of connector is loaded in the location structure of fixing seat, use screw thread or securing member connected mode to connect, simple and convenient, safe and reliable；This utility model simple in construction is firm, safe and reliable, with low cost, easy for installation, change backrest is also convenient for fast, and human feeling in use is splendid, has good economic worth.
