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

[0023] like Figure 1-5As shown, the anti-sinking hardware accessories for doors and windows include a lock seat 1 installed on a frame profile, an axially extending locking platform 11 is provided at the end of the lock seat 1, a guide seat 2 is provided on the locking platform 11, which is installed on the sash profile and partially covers the locking platform 11, the guide seat 2 is provided with a guide slide 21 along the transmission direction, and the guide seat 2 is provided with a roller 3 that can move along the guide slide 21, and the roller 3 sinks or rises during the movement of the guide slide 21 to achieve abutment or separation of the locking platform 11. Preferably, the roller 3 is connected to the transmission member 4 of the handle transmission mechanism, and in the process of rotating the handle, the roller 3 is driven to move and abut or separate from the locking platform 11, so that the door and window sash can be smoothly opened and closed.

[0024] Furthermore, the travel of the guide groove 21 includes a locking section 211 at one end close to the locking platform 11 and an unlocking section 212 at the other end far from the locking platform 11. The roller 3 sinks in the locking section 211, and the peripheral surface of the roller abuts against the locking platform 11 to bear the weight of the closed door and window sash. The roller rises in the unlocking section 212, and the peripheral surface of the roller separates from the locking platform 11, so that the door and window sash can be quickly opened.

[0025] In a preferred embodiment of the present invention, the guide groove 21 is a Z-shaped groove, the locking section 211 and the unlocking section 212 are axial straight grooves of different heights, and a transition inclined groove 213 is provided between the locking section 211 and the unlocking section 212, which is conducive to the smooth movement of the roller 3 in the guide groove 21.

[0026] In a preferred embodiment of the present invention, the unlocking section 212 is an axial straight groove, and the locking section 211 is an oblique groove or an arc groove, and the axial straight groove extends downwardly toward the lock seat 1 to form an oblique groove or an arc groove to form a locking section.

[0027] Furthermore, in order to enhance the tensile strength of the roller 3 when it moves, the roller 3 is connected to the transmission member 4 of the handle transmission mechanism through the connecting member 5, and the connecting member 5 is slidably sleeved on the guide seat 2 to drive the roller 3 to move in the guide slide groove 21. Preferably, a roller seat 51 is provided at the free end of the connecting member 5, and the roller 3 is slidably and lifted on the roller seat 51. Specifically, the roller seat 51 is provided with an inclined groove 511 to cooperate with the roller 3 to move up and down in the guide slide groove 21, and the end of the guide seat 2 near the lock seat 1 is provided with a fixed shaft 22 connected to the fan profile. The fixed shaft 22 is located between the roller seat 51 and the lock seat 1 to prevent the roller seat 51 from excessive movement and causing impact damage.

[0028] Preferably, guide grooves 21 are symmetrically provided on both sides of the guide seat 2, and the roller 3 is provided with a connecting shaft 31. The connecting shaft 31 is movably connected to the roller seat 51 and passes through the guide grooves 21, so that the roller drive 3 moves along the guide grooves 21 on both sides, thereby ensuring the movement stability of the roller 3 and avoiding movement obstruction caused by misalignment.

[0029] Preferably, locking platforms 11 are provided at both ends of the lock seat 1, which is beneficial to symmetrical applicability during installation.

[0030] The transmission member 4 is connected to a locking point 6 that cooperates with the lock seat 1 to lock or unlock. When the present invention is applied to an inward-opening and inward-tilting window sash, the lock seat 1 is preferably axially provided with a rib 12 to prevent the locking point 6 from escaping from above its sliding groove, and the rib 12 extends radially inward from the top of the side wall.

[0031] The preferred guide seat 2 of the present invention is fixedly connected to the fixing part of the corner turner 6 of the door and window sash. When the door and window sash needs to be closed, the handle is rotated, and the transmission member 4 moves away from the lock seat 1, thereby pulling the roller 3 to move to the locking section 211 of the guide slot 21. Figure 3 As shown, the roller 3 and the locking platform 11 abut against the load-bearing door and window sashes to support the closing of the door and window; when the door and window sashes are opened, the handle is rotated, and the transmission member 4 moves toward the direction close to the lock seat 1, thereby pushing the roller 3 to move to the unlocking section 212 of the guide groove 21, as shown in FIG. Figure 4 As shown, in the first half of the unlocking section 212, the roller 3 is separated from the locking platform 11, and the locking point 6 moves to the opening of the lock seat 1, so that the door and window sash can be opened sideways, and the roller 3 continues to move to the end in the unlocking section 212, as shown in FIG. Figure 5 As shown, the locking point 6 moves to the other end of the lock seat 1 to keep the lock seat and the locking point locked, and the roller 3 and the locking platform 11 remain separated, so that the door and window sash can be tilted inwards to open.
