fig. 2 is an assembly schematic diagram of the limiting hinge mechanism with rebound provided by the embodiment.
Detailed Description
The limiting hinge mechanism with rebound of the utility model is further explained with reference to fig. 1 to 2.
The utility model provides a spacing the hinge mechanism that area kick-backed, characterized by: comprises a first connection 1, a second connection plate 2, a rotating shaft 4, a torsion spring 5 and a limit pin 3. First connecting plate 1, torsional spring 5 and second connecting plate 2 suit in proper order is in pivot 4, first connecting plate 1 and second connecting plate 2 can be in pivot 4 circumferential direction, the both ends of torsional spring 5 are fixed in respectively on first connecting plate 1 and second connecting plate 2. The first connecting plate 1 is provided with a limiting groove 122, the end part of the limiting pin 3 is fixed on the second connecting plate 2, and the rod body part of the limiting pin 3 is positioned in the limiting groove 122 to limit the relative rotation range of the first connecting plate 1 and the second connecting plate 2.
Specifically, the first connecting plate 1 and the second connecting plate 2 each include a first connecting portion 11 of an elongated structure and a second connecting portion 12 of a circular structure. The first connecting portion 11 has a connecting hole 22, and the connecting hole 22 is used for connecting a cushion or a backrest frame of a sofa. The center of the second connecting portion 12 is provided with a central hinge hole 121 for the rotating shaft 4 to pass through, the limiting groove 122 is located at the edge of the second connecting portion 12 of the first connecting plate 1, the limiting pin 3 is located on the second connecting portion of the second connecting plate 2, that is, the end of the limiting pin 3 is inserted into the insertion hole 21 of the second connecting portion 12 of the second connecting plate 2.
The first connecting plate 1 and the second connecting plate 2 are both provided with positioning holes 123 for the end 41 of the torsion spring 5 to pass through.
The limiting hinge mechanism with resilience further comprises two overlapped base plates 6, wherein the base plates 6 are located between the first connecting plate 1 and the second connecting plate 2 to separate the first connecting plate 1 from the second connecting plate 2, so that the first connecting plate 1 and the second connecting plate 2 can rotate relatively.
