The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Referring to Fig. 1-Fig. 6, this furniture hinge comprises the holder 2 that joins with wallboard 10, the sliding seat 8 of joining with door-plate 20; Linking arm 1 is arranged on the holder 2, and linking arm 1 joins with bindiny mechanism 14 through front rod 3, back link 4, outer rocker arm 5 and inner rocker arm 6, and front rod 3 one ends and linking arm 1 are hinged; One end of the other end and back link 4 is hinged, and the middle part of back link 4 is hinged through rotating shaft 9 and outer rocker arm 5, and the other end of back link 4 and bindiny mechanism 14 are hinged; Inner rocker arm 6 one ends and outer rocker arm 5 are hinged, and inner rocker arm 6 other ends and bindiny mechanism 14 are hinged, and outer rocker arm 5 is hinged on the linking arm 1; And corresponding linking arm 1 is offered one and is dodged mouth, bindiny mechanism's 14 dismantled and assembled being fixed on the sliding seat 8, and its back link 4 is provided with to block dodges mouth or/and stretch into the guard shield 11 in the outer rocker arm 5; Hinge is opened, and guard shield 11 blocks dodges mouth, as shown in Figure 2; Hinge is closed, and guard shield 11 stretches into outer rocker arm 5, and is as shown in Figure 1.When guard shield 11 did not influence hinge work, it was inner and cause the damage of hinge to prevent effectively that external object from stretching into hinge, and prevented to jam a finger and wait unexpected generation.
