Detailed Description
The invention is further explained below with reference to the drawings:
the C groove in the scheme refers to an installation groove on each side edge of the window sash, and edges on two sides of the C groove are used for clamping and fixing; wherein "vertical," "horizontal," "upper surface," "bottom edge," "side edge," and the like are used for directional references and are used merely for relative positions in a structure to facilitate the description.
Referring to fig. 1 and 2, a hinge structure for doors and windows includes a hinge plate 1, and a fixing clip 2 for fixing a window sash; the fixing clamp plate 2 is of an L shape and comprises a vertical side mounting plate 21 and a transverse bottom mounting plate 22, the upper surface of the bottom mounting plate 22 is provided with a first limiting convex block 221 for clamping a C groove at the bottom of a window sash, the side mounting plate 21 and the hinge plate 1 form a clamping structure for clamping the C groove at the side of the window sash, and the hinge plate 1 corresponds to one surface of the side mounting plate 21 is provided with a second limiting convex block 111 for clamping the C groove at the side of the window sash. The fixed splint 2 is preferably a metal strip which is bent and formed after being punched; the clamping structure is characterized in that the side mounting plate 21 is inserted into a C groove of the window sash, the side mounting plate 21 corresponding to the hinge plate 1 is arranged outside the C groove of the window sash, and the side mounting plate 21 and the hinge plate 1 are locked through screws 100 to clamp edges on two sides of the C groove. The first limit protrusion 221 and the second limit protrusion 111 are usually formed integrally with the fixing splint 2 by stamping or cutting, but may be welded or combined by a plurality of rivets, but the reliability is slightly poor and the cost is higher; the first limit bump 221 and the second limit bump 111 are clamped in the C groove for limiting, which means that two sides of each bump are abutted against two sides of the C groove, so that the bumps and the C groove can be prevented from swinging laterally; the preferred structure of each bump is a square bump along the length direction of the C groove, and two side edges of the bump are abutted with the inner side of the groove edge of the C groove.
The bottom edge C groove and the side edge C groove of the window sash are limited through the first limiting convex block 221 and the second limiting convex block 111 respectively, so that the force causing relative swing between the window sash and the hinge can be dispersed, the stress of a single joint point is reduced, and the stress point of the hinge is mainly distributed on the first limiting convex block 221 and the second limiting convex block 111 which cannot swing, so that compared with a structure that the stress point is on the screw 100, the structure is not easy to loosen even in long-term use and is safer and more reliable; in addition, when the hinge structure is installed, a locking screw 100 or an adjusting clamping plate is not needed between the window sash and the fixing clamping plate 2, and only the clamping structure is locked, so that the structure and the installation are simplified.
In a preferred embodiment, friction surfaces 211 abutting against the inner edges of the sash side C-grooves are provided on both side edges of the side mounting plate 21. Through setting up friction surface 211 can not only strengthen the frictional force between side-mounting board 21 and the casement prevents the relative oscillation, but also can prevent between casement and the side-mounting piece vertical slip and the casement that leads to not smooth with the window frame cooperation. Further, the friction surface 211 is a plurality of parallel ribs protruding from the surface of the side mounting plate 21. The convex ribs are transversely arranged, and the convex ribs can form friction with enough strength after being meshed with the C-shaped groove.
In a preferred embodiment, the first limiting protrusion 221 further has a locking screw passing through it. The locking screw is used for tightly propping up the bottom surface of the C-shaped groove of the window sash, so that the friction force between the bottom mounting plate 22 and the window sash can be enhanced, and the relative swinging can be prevented.
In a preferred embodiment, the first limit protrusion 221 is integrally formed by stamping the bottom mounting plate 22 upward. The integrated into one piece, not only sound construction, processing is simple moreover.
A preferable implementation structure further comprises a window frame fixing plate 3, wherein one end of the window frame fixing plate 3 is hinged to a short cantilever 4 and a long cantilever 5 on the window frame fixing plate 3 respectively, the hinge plate 1 is vertically hinged to the other end of the short cantilever 4, and the other end of the long cantilever 5 is hinged to the bottom mounting plate 22. The hinge structure only comprises a window frame fixing plate 3, two groups of cantilevers and a fixing clamping plate 2, and compared with the traditional multi-connecting-rod hinge, the hinge structure is more simplified in structure, and the hinge cost is greatly reduced.
In a preferred implementation structure, the hinge plate 1 includes a clamping plate portion 11 corresponding to the side mounting plate 21, and a hinge portion 12 having a vertical shaft hole, a fixing shaft 13 is vertically fixed on the short cantilever 4, the fixing shaft 13 is inserted into the shaft hole of the hinge portion 12, and an adjusting screw 14 capable of finely adjusting the height of the hinge plate 1 is further engaged with the top end of the shaft hole through a screw thread. The bottom butt of adjusting screw 14 and the top of fixed axle 13, through rotating adjusting screw 14, with 14 screw-thread fit's of adjusting screw hinge plate 1 can adjust the height, can accomplish the back again and adjust hinge and casement installation, compare with current hinge need carry out the regulation repeatedly of a plurality of points in the installation, installation easy operation, and casement and window frame cooperation are more smooth and easy.
The above description is not intended to limit the technical scope of the present invention, and any modifications, equivalent changes and modifications made to the above embodiments according to the technical spirit of the present invention are all within the scope of the technical solution of the present invention.
