The utility model content
The purpose of this utility model is to overcome the shortcoming that said structure exists, and provide a kind of close angle can arbitrarily angled pause at 15 degree and after greater than 15 degree, smooth more nature during the switch chamber door, close chamber door after the hinge device of closing the door automatically of better tightness.
The utility model is realized with the following methods: comprise main body, and be provided with pull bar in the main body, be connected with first spring between main body and the pull bar, second spring is arranged in the pull bar, second spring, one end connects rolling wheel support, one hook is articulated in pull bar by the 5th rivet, hook one end is buckled on the bearing, rolling wheel support is provided with roller, its described pull bar is provided with arc opening, and the axostylus axostyle of rolling wheel support is inserted in arc opening, is connected to second rivet on the described rolling wheel support sidewall, pull bar inside wall relative set locating piece, second rivet is sliding along the locating piece upper surface.
Described locating piece is oblique setting, and second rivet is oblique at locating piece and slides.
Be respectively arranged with circular arc, arc chimb and arc recess in the described hook, circular arc, arc chimb and arc recess link to each other.
Described pull bar is provided with spring support, and spring support one end peaks at pull bar, and the other end of spring support is connected on the rolling wheel support.
Described arc opening one in keep to the side to be concave shaped.
Described hook is provided with the hook stator.
The beneficial effects of the utility model are: 1, utilize the arc position of hook to contact decision with roller and close corner dimension, adapt to the client greatly at closing time angle requirement, have bigger flexibility; 2, utilize the rivet on pull bar locating piece and the rolling wheel support sidewall to play the support cushioning effect, thereby make chamber door in switching process, compare the smooth more nature of similar in the past product, and the better tightness of chamber door after closing.
