Description

Technical Field

[0001] The utility model relates to the technical field of door and window hinges, in particular to a door and window positioning hinge capable of three-dimensional adjustment. Background Art

[0002] Casement windows are simple in structure, flexible to open and easy to clean, and have good sealing performance when closed. They are widely used window sashes in civil buildings. For different usage scenarios, there is a demand for opening and closing angles of 90° and 180° in the current use process, but most of the existing casement window hinges cannot adjust the opening and closing angles and can only open and close to a certain fixed angle. In addition, since the existing casement windows cannot adjust their air tightness, there are deviations in their up and down, left and right, and front and back positions, which can easily cause doors and windows to sag and break after long-term use. To this end, we propose a three-dimensionally adjustable door and window positioning hinge. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0024] Combined with Figure 1 and attached Figure 2 As shown, a three-dimensionally adjustable door and window positioning hinge includes a window seat connector 10 for installing a window seat, and a window sash connector 20 for connecting with a window sash. A first hinge group 30 and a second hinge group 40 are hingedly arranged between the window seat connector 10 and the window sash connector 20.

[0025] The first hinge group 30 includes a first hinge piece 31 and a second hinge piece 32. One end of the first hinge piece 31 is hinged to the window seat connector 10, the other end of the first hinge piece 31 is hinged to one end of the second hinge piece 32, and the other end of the second hinge piece 32 is hinged to the window sash connector 20.

[0026] The second hinge group 40 includes a third hinge plate 41 and a fourth hinge plate 42. One end of the third hinge plate 41 is hinged to the window seat connector 10, the other end of the third hinge plate 41 is hinged to one end of the fourth hinge plate 42, and the other end of the fourth hinge plate 42 is hinged to the window sash connector 20.

[0027] Combined with Figure 1 and attached Figure 2 As shown, the window sash connector 20 is hingedly arranged at the first hinge shaft 301 of the first hinge group 30, and the window sash connector 20 is provided with a first adjusting member 51 along the Z-axis direction. The first adjusting member 51 is threadedly connected to the window sash connector 20, and a rotating spacer 302 is provided between the lower end of the first adjusting member 51 and the first hinge shaft 301; the first adjusting member 51 is specifically used for adjusting the position of the window sash in the Z-axis direction. When the first adjusting member 51 is screwed, the bottom of the first adjusting member 51 is in rotational contact with the rotating spacer 302, thereby driving the window sash connector 20 to move slightly upward or downward, thereby realizing the adjustment of the position of the window sash along the Z-axis direction.

[0028] Combined with Figure 1 and attached Figure 2As shown, the window sash connector 20 is provided with a second adjusting member 52 along the X-axis direction, the second adjusting member 52 is threadedly connected to the window sash connector 20, and the end of the second adjusting member 52 is in conflict with the window sash. The second adjusting member 52 is specifically used for adjusting the position of the window sash in the X-axis direction. When the second adjusting member 52 is screwed, the second adjusting member 52 drives the window sash connector 20 to move slightly to the left or right relative to the window sash, thereby adjusting the position of the window sash along the X-axis direction.

[0029] Combined with Figure 1 and attached Figure 2 As shown, a third adjusting member 53 is hingedly provided between the first hinge group 30 and the second hinge group 40, and the third adjusting member 53 is an eccentric adjusting screw. The third adjusting member 53 is specifically used for adjusting the position of the window sash in the Y-axis direction. When the third adjusting member 53 is screwed, the third adjusting member 53 adjusts the relative position between the second hinge piece 32 and the third hinge piece 41, so that the window sash connecting member 20 moves slightly forward or backward relative to the window sash, thereby adjusting the position of the window sash along the Y-axis direction.

[0030] Combined with Figure 1 To Attachment Figure 4 As shown, the first hinged piece 31 is provided with a limit screw 311 for limiting the opening angle of the window sash, and the window seat connector 10 is provided with a first protrusion 11 that matches the limit screw 311. The window seat connector 10 is provided with a second protrusion 12 for limiting the first hinged piece 31.

[0031] As attached Figure 3 As shown, when the limit screw 311 is screwed downward, the limit screw 311 is restricted by the first protrusion 11 of the window seat connector 10 when the window sash is opened. At this time, the window sash can only be opened 90°, that is, the opening angle between the window seat connector 10 and the window sash connector 20 is 90°.

[0032] As attached Figure 4 As shown, when the limit screw 311 is screwed upward, the limit screw 311 will not be restricted by the first protrusion 11 of the window seat connector 10 when the window sash is opened. At this time, the window sash can only be opened 180°, that is, the opening angle between the window seat connector 10 and the window sash connector 20 is 180°. When the window sash is opened to 180°, the first hinged piece 31 is restricted by the second protrusion 12, ensuring that the maximum opening angle of the window sash is 180°.

[0033] Combined with Figure 1 and attached Figure 5 As shown, the window seat connector 10 is provided with a fastening bolt 13 for strengthening the connection with the window seat, and a locking piece 14 is connected below the fastening bolt 13. The locking piece 14 is specifically engaged with the profile at the window seat, and by tightening the fastening bolt 13, the locking piece 14 can be driven to clamp the profile at the window seat, thereby strengthening the connection with the window seat.

[0034] Combined with Figure 1 , Attachment Figure 5 and attached Figure 6 As shown, a positioning member 15 is provided at the end of the window seat connector 10, and the positioning member is provided with a first locking screw 16 and an inclined second locking screw 17. The first locking screw 16 and the second locking screw 17 are both locked at the window seat to prevent the window seat connector 10 from sliding along the window seat.

[0035] When the utility model is applied to a window sash, it is specifically installed on the lower side of the window sash, and the upper side of the window sash needs to be combined with an attached Figure 7 The secondary hinge shown in the figure is used to cooperate to ensure the stable opening and closing of the entire window sash.
