Abstract
A hinge opening and closing mechanism at least consists of a first hinged arm and a second hinged arm that are mutually hinged, wherein an elastic element is connected between the first hinged arm and the second hinged arm and two ends of the elastic element are respectively hinged with the first and the second hinged arm. With the elastic element hinged between the two hinged arms, when hinge joints at two ends of the elastic element are on the same straight line with the hinge joints of the two hinged arms, the elastic element is under compressed or stretched state and the elastic force of the elastic element is directed at the hinge joints of the two hinged arms so that the two hinged arms are stressed equally and in the state of relative rest; when the second hinged arm is swayed, the hinge joint between the elastic element and the second hinged arm deflects by taking the hinge joints of the two hinged arms as the center, and meanwhile, the elastic element releases the compressed or stretched force so that the second hinged arm automatically deflects until the force compressing or stretching the elastic element is completely released or the second hinged arm is swayed to an extremely limited position, thus finally realizing the opening or closing of a door body connected with the second hinged arm. The hinge opening and closing mechanism is simple and reasonable in structure, convenient for opening or closing, low in manufacturing cost and wide in application range.

Between the first articulated joint 7 and the second articulated joint 4, also slide and be provided with connecting rod 6, be set in compression spring 5.The first articulated joint 7 and the second articulated joint 4 all take the shape of the letter U, and both sides are coaxially arranged with hinge hole 7.2, and bell and spigot joint 7.1 and 4.1 are extended in bottom.The bell and spigot joint 7.1,4.1 of connecting rod 6 one ends and the first articulated joint 7 is slidably connected, and the other end is fixedly connected with the bell and spigot joint of the second articulated joint; The corresponding bell and spigot joint of interlinking lever end bottom surface annular is provided with limited step 6.1, sees Fig. 5.
Referring to Fig. 6, its operating principle is: suppose that in Fig. 1, the first pivoted arm 1 is to fix, due to, the first pin joint A and the 3rd pin joint C are all on the first pivoted arm, so two fixing some G and some O (corresponding to the first pin joint A and the 3rd pin joint C of Fig. 1) have occurred in Fig. 6; Because the second pin joint B is arranged on the second pivoted arm 3, namely the second pin joint B equates all the time with the 3rd pin joint C distance, and rotate centered by the 3rd pin joint C, one take the some E (in figure, broken circle is the circumference of its motion) that an O moves in a circle as the center of circle so occurred in Fig. 6, point E is L2 to some O distance, point E can change with the distance of some G, is equivalent to tension rail, and minimum length is L1 (namely being in compressive state).When an E moves between an O and some G, and 3 when same straight line, some G and nearest (being that in tension rail, compression spring is in compressive state) of putting between E, and the direction of compression spring power F is pointed to an O all the time, is in equilibrium state.When up swinging some E, make it not on the straight line between a G and some O, the compression spring that is in compressive state starts power is discharged, thereby produce two power F1 ' and F2 ' that point to respectively some O and some E circular motion tangential direction, point G becomes L1 ' (being greater than L1) to the distance of some E, in conjunction with Fig. 4, realized that namely the second pivoted arm 3 is toward the first pivoted arm direction deflection, until the compressed power of compression spring discharges fully; When toward lower swing point E, make it not on the straight line between a G and some O, the compression spring that is in compressive state starts power is discharged, thereby produce two power F1 that point to respectively some O and some E circular motion tangential direction " and F2 ", point G becomes L1 to the distance of some E " (being greater than L1); in conjunction with Fig. 3, realized that namely the second pivoted arm 3 is toward extrinsic deflection, until the compressed power of compression spring discharges fully.
Referring to Fig. 7-Figure 11, the first pivoted arm 1 outer end and the second pivoted arm 3 are hinged, and the first articulated joint 7 of middle part and tension rail 2 and the middle part of the 3rd pivoted arm 9 are hinged, inner hinged with fixed arm 10; The second pivoted arm other end and sliding seat 11 are hinged, hinged with inboard and second articulated joint 4 of the first pivoted arm hinged place; The 3rd pivoted arm rear end is hinged with fixed arm by the 4th pivoted arm 14, and front end and sliding seat are hinged; Fixed arm and holder 8 join; First, second, third, fourth pivoted arm all is channel steel shape.Holder 8 is arranged on furniture cabinet 12, and sliding seat 11 is arranged on furniture door body 13.Fig. 9 is the view of furniture door body hinge while being in open mode, and Figure 10 is the view of furniture door body hinge while being in closed condition, and Figure 11 is the view of furniture door body hinge while being in semi-open state.
The second embodiment
Elastic component is stayed mast, between comprising, is connected with the first articulated joint and second articulated joint of tension spring, and two articulated joints are hinged with the first pivoted arm, the second pivoted arm respectively.Wherein, the point hinged with the first pivoted arm is the first pin joint, and the point hinged with the second pivoted arm is the second pin joint, and the hinged point of the first pivoted arm and the second pivoted arm is the 3rd pin joint, and the second pin joint is positioned at the 3rd pin joint outside, all not shown in figure.Other does not state part with the first embodiment.
Referring to Figure 12, its operating principle is: suppose that the first pivoted arm is to fix, due to, the first pin joint and the 3rd pin joint are all on the first pivoted arm, so two fixing some G ' and some O ' have occurred in Figure 12; Because the second pin joint is arranged on the second pivoted arm, namely the second pin joint equates all the time with the 3rd pin joint distance, and rotate centered by the 3rd pin joint, one take the some E ' (in figure, broken circle is the circumference of its motion) that an O ' moves in a circle as the center of circle so occurred in Figure 12, point E ' is L2 to some O ' distance, point E ' can change with the distance of some G ', is equivalent to stayed mast, and maximum length is L3 (namely being in extended state).When an E ' moves between an O ' and some G ', and 3 when same straight line, the distance maximum (being that in stayed mast, tension spring is in extended state) between some G ' and some E ', and the direction of tension spring power T is pointed to an O ' all the time, is in equilibrium state.When up swinging some E ', make it not on the straight line between a G ' and some O ', the tension spring that is in extended state starts power is discharged, thereby produce two power T1 ' and T2 ' that point to respectively some O ' and some E ' circular motion tangential direction, point G ' becomes L3 ' (being less than L3) to the distance of some E ', namely realize the arm deflection be connected with O ', until the power that tension spring is stretched discharges fully; When toward lower swing point E ', make it not on the straight line between a G ' and some O ', the tension spring that is in extended state starts power is discharged, thereby produce two power T1 that point to respectively some O ' and some E ' circular motion tangential direction " and T2 ", point G ' becomes L3 to the distance of some E ' " (being less than L1); namely realize the arm deflection be connected with O ', until the power that tension spring is stretched discharges fully.
