Description
Technical field
The utility model relates to a kind of bindiny mechanism, particularly relates to a kind of bindiny mechanism for seat backrest adjustment attitude.
Background technology
Current consumer and manufacturer are proposed new requirement for the function of seat backrest, common fixed backrest in use and transport in compared with the thing to sit on of adjustable backrest attitude, all embodied obvious inferior position, therefore the thing to sit on market acceptance of backrest regulating posture is higher.That in the market the thing to sit on of existing adjustable backrest attitude, the bindiny mechanism of its adjustment attitude is divided into two kinds substantially, one is that simple loose-leaf connects, undertaken spacing by the parts of banking pin and so on, the connecting-piece structure of this class formation is simple, but, due to the inherent shortcoming of loose-leaf itself, cause its service life short, structural strength is not high, and has the turnover defect such as not in place.Another kind of structure as publication number for: the technology type disclosed in CN204169384U patent seemingly, is be connected by movable axis between backrest with thing to sit on body, by connecting rod spring, or it is spacing that the parts such as the sliding tenon of chute carry out connection, this type of mechanism structure is complicated, and install difficulty, reliability is also not high.So how to make a kind of simple and convenient reliably for the bindiny mechanism of seat backrest adjustment attitude, just inventor's problem that will solve.
Summary of the invention
The utility model solve in prior art for seat backrest adjustment attitude bindiny mechanism or structural strength is not good, service life is short, or install complicated, the defect of poor reliability, provide a kind of can the installation of simple and fast, simultaneously long service life, the bindiny mechanism for seat backrest adjustment attitude simple and reliable for structure.
Its concrete technical scheme is: a kind of bindiny mechanism for seat backrest adjustment attitude, comprise the connector be fixedly connected with backrest, described connector is provided with two axis holes, on described axis hole, movable axis is connected to connecting rod A and connecting rod B, described connecting rod A and connecting rod B one end are coupling by axis hole and connector activity, the other end is coupling by another axis hole and fixed bar activity, and described fixed bar is fixedly connected with thing to sit on body.The utility model make use of the principle of four bar structures, and its two limits fix thing to sit on body and backrest respectively, utilizes the rotation of connecting rod to adjust backrest attitude, and its structure is simple and firm.
As preferably, the ratio of the spacing between the centre bore of two axis holes that described fixed bar and connecting rod A and connecting rod B activity are coupling and the spacing between connecting rod A two axis hole centre bore is 1:0.96 ~ 1.16.
As preferably, the ratio of the spacing between the centre bore of two axis holes that described fixed bar and connecting rod A and connecting rod B activity are coupling and the spacing between connecting rod B two axis hole centre bore is 1:0.72 ~ 0.92.
As preferably, the ratio of the spacing between the centre bore of two axis holes that described fixed bar and connecting rod A and connecting rod B activity are coupling and the spacing between connector two axis hole centre bore is 1:0.48 ~ 0.68.The angle change that the utility model utilizes the four bar structure length of sides not wait and produces when its deformation adjusts the angle of backrest and vertical plane, compares Axile connection structure, the lower and sound construction of its cost.
As preferably, described connecting rod B is arc, and its position, arc top and connecting rod A one end form position limiting structure.Described connecting rod B3 is arc, and movement locus when making connecting rod A2 one end position, arc top offsets with it shortens, and the radian of connecting rod B3 plays position-limiting action, and the simple shape changing connecting rod B3 can be avoided arranging the parts such as banking pin, simplifies technique.
The utility model utilizes Length discrepancy four bar structural principle to achieve the adjustment back and forth of the vertical attitude of backrest and horizontal attitude, its structure is simply firm, easy for installation, the transformation for existing product can realize without the need to changing basic structure, has good economic worth.

Detailed description of the invention
Embodiment 1
Below in conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, the utility model embodiment 1 is described in further detail:
A kind of bindiny mechanism for seat backrest adjustment attitude, comprise the connector 1 be fixedly connected with backrest 5, described connector 1 is provided with two axis holes, on described axis hole, movable axis is connected to connecting rod A2 and connecting rod B3, described connecting rod A2 and connecting rod B3 one end are coupling by axis hole and connector 1 activity, the other end is coupling by another axis hole and fixed bar 4 activity, and described fixed bar 4 is fixedly connected with thing to sit on body 6.Described thing to sit on body 6 is sofa, and when described backrest 5 state is vertical state, backrest 5 uses as backrest; When described backrest 5 is level, described backrest 5 back side can be used as tea table or desktop uses.Described in the present embodiment, between fixed bar 4, connecting rod A2, connecting rod B3 and connector 1 upper shaft hole centre bore, the ratio of spacing is: 15:16:12:9, when connecting rod B3 one end props up connecting rod A2, described connector 1 uses as tea table for level for horizontal direction and backrest 5, when connecting rod A2 one end props up connecting rod B3, described connector 1 is vertical direction and backrest 5 is vertical state.Described connecting rod B3 is arc, and movement locus when connecting rod A2 one end is offseted with it shortens, and the radian of connecting rod B3 plays position-limiting action.
