Please refer to fig. 1 to 8. An embodiment of the utility model provides a hinge for door and window, it includes bottom plate 1, mount pad 2, bearing arm 3, first support arm 4 and second support arm 5, the bottom plate 1 the mount pad 2 bearing arm 3 with first support arm 4 constitutes four-bar linkage, 5 auxiliary stay of second support arm increase bearing capacity, strengthen overall structure's atress. Specifically, when door and window opened a wide angle, if bearing arm 3 with mount pad 2 is located same straight line, bottom plate 1 the mount pad 2 bearing arm 3 with first support arm 4 forms the triangle-shaped space, second support arm 5 will the triangle-shaped space falls into two similar little triangle-shaped spaces, has increased the support between the structure, plays stable in structure, improves the beneficial effect of bearing.
The bottom plate 1 is connected with a frame 9, and the mounting seat 2 is connected with a fan 10. The frame material end of the bearing arm 3 is hinged to the base plate 1, and the fan material end of the bearing arm 3 is hinged to the mounting base 2. The frame material end of the first supporting arm 4 is hinged to the base plate 1, and the fan material end of the first supporting arm 4 is hinged to the mounting seat 2. One end of the second supporting arm 5 is hinged to the middle section of the bearing arm 3, and the other end of the second supporting arm 5 is hinged to the middle section of the first supporting arm 4.
Specifically, the fan material end of the first support arm 4 is provided with a first groove 41, and the hinged end of the second support arm 5 and the bearing arm 3 is provided with a recessed port 51 matched with the fan material end of the first support arm 4 and a second groove 52 matched with the first groove 41. In particular, the indentation 51 is a semicircular notch. When door and window closes, first support arm 4 with second support arm 5 is folding, first recess 41 keeps away the space with second recess 52 each other, and when folding, first support arm 4 with the width of second support arm 5 with the width phase-match of bottom plate 1, first recess 41 with second recess 52 festival has reduced overall structure's volume.
Specifically, a sliding notch 53 is formed in one end, hinged to the first support arm 4, of the second support arm 5, and the second support end passes through the sliding notch 53 through a rivet to be hinged to the first support arm 4. The extending direction of the sliding groove opening 53 is matched with the moving track orientations of the first supporting arm 4 and the second supporting arm 5, and the sliding groove opening has a certain degree of freedom in the process of moving the hinge for doors and windows, so that the sliding groove opening moves more smoothly.
The middle section of the bearing arm 3 is provided with a connecting hole 31, and one end of the second supporting arm 5 is hinged to the bearing arm 3 through a rivet and the connecting hole 31.
The top of bottom plate 1 is provided with spacing post 11, spacing post 11 is located the bearing arm 3 with between the first supporting arm 4, spacing post 11 restriction the bearing arm 3 is past 4 frame material ends of first supporting arm rotate. The height of the limiting column 11 is matched with that of the bearing arm 3. Spacing post 11 effective restriction the opening angle of bearing arm 3 prevents that door and window from opening the back and blowing door and window because of the typhoon and cause the too big situation that causes door and window damage of opening angle.
Preferably, the hinge for doors and windows further comprises a bearing gasket 7, the bearing gasket 7 is arranged at the top end of the bottom plate 1, and the bearing arm 3 penetrates through the bearing gasket 7 through a rivet and is hinged to the bottom plate 1. The bearing gasket 7 is made of high-density brass or plastic, and prevents the bearing arm 3 and the base plate 1 from generating noise due to friction on the same material plane, so that the silencing effect is achieved.
Preferably, the hinge for doors and windows further comprises a mounting gasket 8, the mounting gasket 8 is arranged at the bottom end of the mounting seat 2, and the first support arm 4 penetrates through the rivet to be arranged on the mounting gasket 8 and is hinged to the mounting seat 2. The mounting pad 8 is provided with a top corner 81, the bottom plate 1 is provided with a positioning piece 12 matched with the top corner 81, and the positioning piece 12 surrounds the outer edge of the top corner 81. The insertion part 12 is inserted into the frame material 9 during installation, so that the stability of the bottom plate 1 is increased.
The mounting base 2 is provided with a limiting piece 21, a limiting pressing piece 22 and a limiting screw 23, the limiting pressing piece 22 is arranged on the inner side of the limiting piece 21, and the limiting screw 23 is arranged on the outer side of the limiting piece 21. The limiting piece 21, the limiting pressing piece 22 and the limiting screw 23 are used for installing the installation base 2 and the fan material 10.
Compared with the prior art, the utility model discloses a stability of hinge is guaranteed to a plurality of articulated connecting rods, wholly is not provided with spout and slider isotructure, is difficult to long-pending dust, uses the resistance increase, blocks the scheduling problem that does not easily appear yet for a period. In addition, the second supporting arm is arranged, so that the overall stability is increased, and the bearing capacity is improved.
