[0022] The present invention will be further described in detail below with reference to specific embodiments.

[0023] like Figure 1-4 As shown, a connection device for a door and window hinge and a door and window sash includes a sash connecting seat 1 for connecting the door and window sash and a connecting member 2 for connecting the hinge 100. The sash connecting seat 1 has a receiving cavity 11 with an opening opposite to the hinge 100. The connecting member 2 has a plug-in part 21 that can extend into the receiving cavity 11. The plug-in part 21 has a lock hole 211. A locking member 3 is transversely inserted through the sash connecting seat 1, extending into the lock hole 211 and abutting against the inner wall of the sash connecting seat 1. The locking member 3 does not penetrate the sash connecting seat 1 and does not abut against the door and window sash profile, avoiding damage to the profile due to prolonged contact. At the same time, there is no need to worry about excessive force damaging the profile when tightening the locking member 3, which facilitates the disassembly and assembly of the door and window sash and also makes it easy to replace and maintain the connection device.

[0024] In this invention, the sash connecting seat 1 includes a insertion groove 12 that matches the door / window sash profile. The outer wall of the sash connecting seat 1 has a through hole 13 communicating with the receiving cavity 11. A locking member 3 passes through the through hole 13 and the locking hole 211 of the insertion part 21 to lock the sash connecting seat 1 and the connecting member 2. The locking member 3 and the insertion part 21 of the connecting member 2 are connected in a non-axial butt joint manner, improving the connection stability and preventing loosening over time. Preferably, the axis of the locking hole 211 is perpendicular to the insertion direction of the insertion part 21, meaning the locking member 3 is connected perpendicular to the insertion part 21, making the connection between the sash connecting seat 1 and the connecting member 2 more stable. The locking member 3 is preferably a screw, facilitating quick and easy assembly and disassembly of the door / window sash.

[0025] Furthermore, the insertion groove 12 divides the sash connector 1 into an inner seat 14 and an outer seat 15, with the outer seat 15 being thicker and wider than the inner seat 14. The insertion groove 12 is mortised and tenoned with the I-beam groove of the door and window sash profile. The inner seat 14 is inserted into the profile groove of the door and window sash, forming the inner side of the sash connector 1, while the outer seat 15 forms the outer side of the sash connector 1. The locking member 3 passes through the outer seat 15 and extends into the receiving cavity 11 to lock the insertion part 21 of the connector 2. The outer seat 15 is relatively thicker, resulting in better connection strength. The outer surface of the outer seat 15 is curved, and the cap end of the locking member 3 is embedded in the sash connector 1 or flush with the outer surface of the sash connector 1, which makes the connected device more aesthetically pleasing and simple after installation.

[0026] Preferably, the connector 2 includes a connecting plate 22 for connecting the hinge support arm 101, and a plug-in part 21 is provided at one end of the connecting plate 22 and integrally formed with the connecting plate 22 for easy plugging.

[0027] In a preferred embodiment of this utility model, the connector 2 further includes a limiting plate 23 disposed between the connecting plate 22 and the hinge support arm 101. The two sides of the limiting plate 23 align with the inner sides of the opening of the door / window sash profile, and the limiting plate 23 gradually widens from its free end toward the sash connecting seat 1. During the process of the connecting plate 22 being inserted into the profile groove, the limiting plate 23 gradually locks into the two side walls of the profile groove opening, preventing the hinge from wobbling between the door / window sash and the door / window sash.

[0028] Furthermore, the connecting plate 22 is inserted into the profile groove of the door and window sash profile, and the connecting plate 22 is provided with a protrusion 221 to increase the thickness of the side portion of the connecting plate 22 extending into the profile groove. When the connecting plate 22 is inserted into the profile groove, the protrusion 221 abuts against the inner wall of the profile groove to prevent the hinge from loosening up and down within the door and window sash profile. Preferably, at least one protrusion 221 is symmetrically provided on both sides of the connecting plate 22 for a tighter engagement.
