Detailed Description

The present invention is described in further detail below with reference to the attached drawing figures.

As shown in fig. 1 to 5, the high sealing and high bearing dustproof hinge comprises a bottom plate 1 for being mounted on a window frame, a short rod 2 and a long rod 3 which are hinged with the bottom plate 1, a support arm 4 which is hinged with the short rod 2 and the long rod 3, and the short rod 2 is provided with an adjusting piece 5 for adjusting the tightness between the short rod 2 and the bottom plate 1. Preferably, the adjusting element 5 is an adjusting screw. The adjusting piece 5 is rotated, so that the connection tightness between the short rod 2 and the bottom plate 1 can be adjusted, and the smooth degree of the rotation of the short rod 2 can be adjusted. The utility model has simple structure, the adjusting piece 5 is arranged on the short rod 2, the hinge tightness of the adjusting piece can be easily adjusted, and the bottom plate 1 is only provided with a screw hole and has no sliding groove opening, so that the rotating smoothness of the short rod 2 can not be influenced by excessive dust accumulation even if the use time is long or the windy and sandy area is large.

In a preferred embodiment of the utility model, a boss 6 is arranged on the bottom plate 1, one end of the long rod 3 connected with the support arm 4 is provided with a bending part 31 matched with the boss 6, and the bending part 31 is hinged with the support arm 4. When the hinge is closed, the bending part 31 of the long rod 3 is arranged on the boss 6, so that the hinged end of the long rod 3 and the support arm 4 is supported, and the window sash is prevented from sagging. Preferably, a convex part 11 is arranged between the bottom plate 1 and the long rod 3 to strengthen the supporting force of the other end of the long rod 3 and further prevent the window sash from drooping; the bottom of the bending part 31 can be provided with a guide cambered surface 311, so that the bending part 31 can prevent the boss 6 from being damaged when the long rod 3 is closed. More preferably, the boss 6 has a limiting portion 61 matched with the side edge of the short rod 2, so as to prevent the window sash from being damaged by being opened excessively due to the fact that the short rod 2 is rotated excessively when being opened.

Further preferably, a connecting plate 7 is arranged between the short rod 2 and the bottom plate 1, the boss 6 is arranged on the connecting plate 7, and the boss 6 and the connecting plate 7 are preferably integrally formed to avoid abrasion to the bottom plate 1. Of course, the connecting plate 7 can also directly cover the boss 6 and part of the base plate 1, so that the base plate 1 and the boss can be protected from abrasion.

In another preferred embodiment of the utility model, the short bar 2 forms an obtuse angle with the proximal end of the base plate 1 when the hinge is fully opened. Namely: after the short rod 2 and the bottom plate 1 are completely opened, the hinge point of the short rod 2 and the support arm 4 is arranged between the hinge point of the short rod 2 and the bottom plate 1 and the hinge point of the long rod 3 and the bottom plate 1, the included angle between the short rod 2 and the support arm 4 is also an obtuse angle, and the hinge point of the short rod 2 and the bottom plate 1 is shortest from the window sash mounting end of the bottom plate 1. Thus, the length of the short rod 2 can be further shortened, and the bearing of the bracket arm 4 is increased.
