Utility model content
The purpose of this utility model, is in order to solve the problem in background technology, and a kind of hinge for divan is provided.
Above-mentioned technical purpose of the present utility model is achieved by the following technical programs:
For a hinge for divan, comprising: fixed bar, the first rocking bar, the second rocking bar, swing arm, head rod and the second connecting rod; Described fixed bar is in order to fixed position; The two ends of fixed bar are hinged with the bottom of the first rocking bar and the second rocking bar respectively; The middle part of the first rocking bar and the second rocking bar is hinged with respectively two of swing arm; The top of the first rocking bar and the second rocking bar is hinged with respectively head rod and the second connecting rod; Hinged between head rod and the second connecting rod. Fixed bar, the first rocking bar, the second rocking bar, swing arm form a four-bar linkage, and fixed bar fixedly makes the first rocking bar, the second rocking bar in certain angle, to swing, thereby makes to form different angles between head rod and the second connecting rod. Head rod and the second connecting rod are set on the first rocking bar and the second rocking bar has increased the switching performance of hinge and sofa bedstead.
As preferably, one end bending of described fixed bar extends to form a tabs; On described tabs, be fixedly connected with elastic component, described elastic component one end is fixed on described tabs, and the other end is fixed in described the first rocking bar or the second rocking bar on far away that of tabs described in distance. The variation that elastic component provides pulling force to contribute to hinge in the time that hinge is movable, and in the time that duty is arrived in hinge activity, also can provide coupling mechanism force.
As preferably, described swing arm is an arc lamellar body, makes hinge in the time of activity, and head rod and the second connecting rod can not bump against with swing arm.
As preferably, described head rod and the second connecting rod are the sheet sheet metal component of " L " shape, have strengthened the switching performance of hinge and sofa bedstead.
As preferably, the excursion of the angle between described head rod and the second connecting rod is 90 °～180 °, thereby has ensured the turnover angle of divan.
As preferably, on described swing arm, be provided with the groove for strengthening, in order to increase the intensity of swing arm.
As preferably, on described the first rocking bar or the second rocking bar, be provided with the brace for fixing elastic component.
As preferably, on described tabs, be provided with the locating hole for fixing elastic component, when use, being only fixedly connected with of elastic component just can need to be realized to through locating hole in one end of elastic component.
In sum, the beneficial effects of the utility model:
1. a kind of hinge arrangement for divan described in the utility model is simple, and switching performance is good.
2. a kind of hinge for divan self described in the utility model is light and structural strength is high.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is a kind of structural representation that uses state of the utility model.
Detailed description of the invention
Following specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; those skilled in the art are reading after this description and can make to the present embodiment the amendment that there is no creative contribution as required, but as long as within the scope of claim of the present utility model, are all subject to the protection of Patent Law.
The utility model is elaborated with embodiment below in conjunction with accompanying drawing.
Embodiment 1:
Shown in Fig. 1, Fig. 2, a kind of hinge for divan, comprising: fixed bar 1, the first rocking bar 2, the second rocking bar 3, swing arm 4, head rod 5 and the second connecting rod 6; Fixed bar 1 is in order to fixed position; The two ends of fixed bar 1 are hinged with the bottom of the first rocking bar 2 and the second rocking bar 3 respectively; The middle part of the first rocking bar 2 and the second rocking bar 3 is hinged with respectively two of swing arm 4; The top of the first rocking bar 2 and the second rocking bar 3 is hinged with respectively head rod 5 and the second connecting rod 6; Hinged between head rod 5 and the second connecting rod 6. Fixed bar 1, the first rocking bar 2, the second rocking bar 3, swing arm 4 form a four-bar linkage, fixed bar 1 fixedly makes the first rocking bar 2, the second rocking bar 3 in certain angle, to swing, thereby makes to form different angles between head rod 5 and the second connecting rod 6. Head rod 5 and the second connecting rod 6 are set on the first rocking bar 2 and the second rocking bar 3 has increased the switching performance of hinge and sofa bedstead.
One end bending of fixed bar 1 extends to form a tabs 11; On tabs 11, be fixedly connected with elastic component 7, elastic component 7 one end are fixed on tabs 11, and the other end is fixed on far away that of distance tabs 11 in the first rocking bar 2 or the second rocking bar 3. The variation that elastic component 7 provides pulling force to contribute to hinge in the time that hinge is movable, and in the time that duty is arrived in hinge activity, also can provide coupling mechanism force.
