The middle part of mounting panel is equipped with the second bar hole along its length direction, the other end of first extension board passes through the rivet and slides and rotate in the second bar hole.
The outer end of mounting panel is equipped with the regulation seat, it is connected with the regulating block to adjust the seat, regulating block, regulation seat pass through adjusting screw and connect, adjusting screw sets up along the length direction of mounting panel.
The utility model adopts the four-bar mechanism consisting of the frame fixing plate, the first support plate, the second support plate and the mounting plate to realize the inward opening state of the window sash, and has the advantages of simple integral structure, convenient installation and simple and convenient operation.
Drawings
FIG. 1 is a schematic perspective view of the 90-degree concealed inward-opening inward-falling hinge of the present invention in a folded state;
fig. 2 is a schematic view of the 90-degree concealed inward-opening inward-falling hinge shown in fig. 1.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, the 90-degree hidden inward-opening inward-falling hinge comprises a frame fixing plate 1, a first support plate 2, a second support plate 3 and a sash fixing plate 4 which are sequentially stacked, wherein the first support plate 2 and the second support plate 3 are arranged in a crossed manner, the crossed positions of the first support plate 2 and the second support plate 3 are connected in a rotating manner, and the rotating connections are preferably hinged.
One end of the first support plate 2 is connected with the frame fixing plate 1 in a sliding mode along the length direction of the frame fixing plate 1, the fan fixing plate 4 comprises a mounting plate 41 and a mounting block 42 which are vertically crossed, the other end of the first support plate 2 is connected with the mounting plate 41 in a sliding mode along the length direction of the mounting plate 41, one end of the second support plate 3 is connected with the frame fixing plate 1 in a rotating mode, and the other end of the second support plate 3 is connected with the crossed position of the mounting plate 41 and the mounting block 42 in a rotating mode. One end of the frame fixing plate 1 is provided with a first strip-shaped hole 5 along the length direction of the frame fixing plate, and one end of the first support plate 2 slides and rotates in the first strip-shaped hole 5 through a rivet. The middle part of the mounting plate 41 is provided with a second bar-shaped hole 6 along the length direction thereof, and the other end of the first support plate 2 slides and rotates in the second bar-shaped hole 6 through a rivet. The outer end of mounting panel 41 is equipped with adjusts seat 7, adjusts seat 7 and is connected with regulating block 8, and regulating block 8, regulation seat 7 pass through adjusting screw 9 and connect, and adjusting screw 9 sets up along mounting panel 41's length direction. The adjusting seat 7, the fan fixing plate 4 and the window sash are driven to move through the screw transmission of the adjusting screw 9, so that the window sash is adjusted in the left-right direction. The mounting block 42 fits into a slot in the sash to engage the profile.
The 90-degree hidden inward-opening inward-reversing hinge is used as a lower hinge of an inward-opening inward-reversing window and is arranged at the bottom of a window sash and the bottom of a window frame. And pulling the window sash, and alternately expanding the first support plate 2 and the second support plate 3 until the window sash fixing plate 4 and the frame fixing plate 1 form an angle of 90 degrees. The inward opening state of the window sash is realized by a four-bar linkage mechanism consisting of the frame fixing plate 1, the first support plate 2, the second support plate 3 and the sash fixing plate 4. When the window sash is in the inward falling state, the frame fixing plate 1, the first support plate 2, the second support plate 3 and the sash fixing plate 4 are in the folded state, and the inward falling state is realized by the upper hinge. The whole structure is simple, the installation is convenient, and the operation is simple and convenient.
What has been described above are merely some embodiments of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the utility model.
