The elastic member can hinder the buffer component from sliding to the bottom of the mounting groove. The side of the second hinge plate close to the mounting groove is provided with an abutting portion, which can abut against the buffer component.
[0006] As an improvement of the above technical solution, the elastic member is arranged in the interior of the mounting groove, one end of the elastic member abuts against or is connected to the bottom of the mounting groove, and the other end abuts against or is connected to the end of the buffer component.
[0007] As an improvement of the above technical solution, the buffer component comprises a buffer member and a guide column.
[0008] The buffer member is provided with an elastic member mounting groove with an opening facing the mounting groove, and the elastic member mounting groove is provided with the guide column connected thereto in a sliding manner, and the end of the guide column abuts against the mounting groove. The elastic member is arranged in the elastic member mounting groove, one end of the elastic member abuts against or is connected to the bottom of the elastic member mounting groove, and the other end abuts against or is connected to the end of the guide column.
[0009] As an improvement of the above technical solution, one end of the buffer component facing the second hinge plate is provided with an abutting groove, and the bottom surface of the abutting groove is an inclined surface inclined toward the second hinge plate.
[0010] As the improvement of the above technical scheme, the back surface of the first hinge plate and the second hinge plate is provided with a supporting block.
[0011] As the improvement of the above technical scheme, the elastic member is a compression spring.
[0012] As the improvement of the above technical scheme, the front surface of the second hinge plate is further provided with an avoiding groove corresponding to the position of the mounting groove.
[0013] Correspondingly, the utility model also provides a door and window which comprises the buffer hinge.
[0014] The utility model has the advantages of the following:
[0015] The buffer device is arranged on the first hinge plate and the second hinge plate to buffer the impact generated when the door and window are closed. Specifically, the mounting groove on the first hinge plate is provided with an elastic member and a buffer component connected through sliding, the elastic member can hinder the buffer component from sliding to the bottom of the mounting groove, and the second hinge plate is provided with an abutting portion. During the unfolding of the first hinge plate and the second hinge plate, the abutting portion contacts the buffer component, and the impact force generated when the door and window are closed is buffered under the action of the elastic member, thereby prolonging the service life of the hinge and reducing the noise when the door is closed.
