detailed description

As shown in Figure 1 and Figure 2, a invisible hinge with good stability described in the utility model includes a fixed seat 1, a connecting seat 2, a main connecting rod 3, a long connecting rod 4, a short connecting rod 5, a sliding Shaft 6, adjustment block 7, adjustment screw 8, several rivets 9, rubber washer 10, hinge shaft 20, positioning screw 30, wherein the fixing base 1 includes a vertical fixing part 11 and a horizontal fixing part 12 arranged in an "L", the A number of countersunk holes 13 and limiting protrusions 14 are respectively made on the vertical fixing part 11 and the horizontal fixing part 12, and a chute hole 121 is made on the horizontal fixing part 12; When it is on the window frame, a limit groove matching the limit protrusion 14 will be made on the window frame, thereby effectively limiting the position of the fixing seat 1; the countersunk hole 13 is used for the threading of the fixing screw. , to fix the fixing seat 1 on the window frame. The connecting seat 2 includes a vertical connecting portion 21 and a horizontal connecting portion 22 arranged in an “L” shape. The vertical connecting portion 21 is formed with an embedded groove 211 and a reinforcing connecting portion 212 . One end of the reinforcing connecting portion 212 An embedding hole 40 is made, and the other end of the reinforcing connection part 212 is made with a screw hole 50 communicating with the embedding hole 40, and the end of the horizontal connecting part 22 is made with a clamping head 221. A waist-shaped hole 222 is also made on the horizontal connecting portion 22 ; wherein, the setting of the waist-shaped hole 222 can facilitate the adjustment of the position of the connecting seat 2 . The long connecting rod 4 is made with a high connecting end 41 and a low connecting end 42; the long connecting rod 4 is made into a structure with high and low ends, in order to leave enough storage space for each connecting rod after being folded together . The end of the adjusting block 7 is formed with a locking groove 71 and a mounting groove 72 , and the locking groove 71 and the mounting groove 72 are connected.

As shown in Figures 1 and 2, one end of the hinge shaft 20 is embedded in the embedding hole 40, and the set screw 30 is locked in the screw hole 50 so that the end of the set screw 30 is aligned with the end of the hinge shaft 20. In contact, one end of the main connecting rod 3 is hinged on the horizontal fixing part 12 through a rivet 9, one end of the short connecting rod 5 is hinged on the horizontal connecting part 22 through a rivet 9, and the other end of the short connecting rod 5 The other end of the main connecting rod 3 is hinged by a rivet 9, the high connecting end 41 of the long connecting rod 4 is hinged on the other end of the hinge shaft 20, and the sliding shaft 6 is slidably arranged in the chute hole 121, so The low connection end 42 of the long connecting rod 4 is hinged on the sliding shaft 6, and the rubber washer 10 is arranged at the hinge joint between the low connection end 42 and the sliding shaft 6 and isolates the low connection end 42 from the horizontal fixing part 12. The middle part of the long connecting rod 4 is hinged with the middle part of the main connecting rod 3 through a rivet 9, and the adjusting block 7 is fixed on the clamping head 221 of the horizontal connecting part 22 through the clamping groove 71, and the nut of the adjusting screw 8 The threaded end of the adjustment screw 8 is locked on the clamping head 221 in the clamping groove 71 . Wherein, a rubber sleeve 60 is set on one end of the hinge shaft 20 embedded in the embedding hole 40 to increase the friction between the hinge shaft 20 and the embedding hole 40 and prevent the hinge shaft 20 from getting loose. From the above description and in conjunction with FIG. 2 , it can be seen that when the set screw 30 is tightened with a wrench, the set screw 30 can move against the hinge shaft 20 , so that the long connecting rod 4 hinged with the hinge shaft 20 will move. Certainly, when the long connecting rod 4 moves, the force will act on the connecting seat 2, so that the connecting seat 2 is far away from the long connecting rod 4, thereby meeting the requirement of adjusting the vertical tightness of the window. The invisible hinge with high stability described in the utility model adopts the above-mentioned technical scheme, and the invisible hinge with good stability is designed with a very scientific and reasonable structure, low processing difficulty, and low design cost. The invisible hinge with good stability described in the utility model has only one chute hole 121 in its components, and other movable parts are connected together by hinged mode respectively. In this way, after the invisible hinge with good stability is applied to the window, the operation of the window will be made more stable without jamming, which is beneficial to prolong the service life of the window.
