[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0032] like Figure 1-7 As shown, a single-frame double-leaf sliding window comprises:
[0033] Rotating a roller 3 disposed on the window sash 1;
[0034] A track 2 for the roller 3 to roll on;
[0035] Width limiting components, including
[0036] A movable seat 6 slidably mounted on the track 2;
[0037] A stopper 5 disposed on the movable seat 6 to block the roller 3;
[0038] The limiting member 5 includes a rotatably arranged pawl 51, and a rotating clamp 52 is fixedly arranged on the pawl 51;
[0039] The track 2 is provided with a special-shaped limit rail 4 which can form a single-row sliding fit with the pawl 51 .
[0040] Specifically, a windproof strip is embedded on the side of the window sash 1, and a drainage hole is provided on the track 2. A torsion spring is provided on the rotating shaft of the ratchet 51 to keep the ratchet 51 at a fixed angle.
[0041] Furthermore, users can Figure 2In the window opening direction shown, the movable seat 6 slides along the special-shaped limit rail 4 until it stops at a predetermined width. The movable seat 6 drives the pawl 51 and the rotating clamp 52 to move on the special-shaped limit rail 4, and the pawl 51 is made to slide unidirectionally along the window opening direction through the torsion spring, and is fixed as the movable seat 6 stops. At this time, the pawl 51 blocks the rotating axis of the roller 3, thereby blocking the window sash 1 and controlling the window opening width.
[0042] In the above technology, through the one-way sliding cooperation between the pawl 51 and the special-shaped limit rail 4, the position of the movable seat 6 can be slid and adjusted according to the user's needs, and locked when stopped, and the window opening width is limited by the obstruction between the pawl 51 and the rotating shaft of the roller 3.
[0043] As an embodiment further provided by the present invention, the special-shaped limiting rails 4 are arranged on both sides of the track 2, and are provided with limiting grooves 43 arranged equidistantly, and the limiting grooves 43 are used to clamp the rotating clamp 52 to limit the limiting member 5.
[0044] Specifically, since the torsion spring is disposed on the rotation axis of the pawl 51, the rotating clamp 52 always maintains a clockwise rotation trend. Figure 2 The movable seat 6 is slidable in the window opening direction as shown. During the unidirectional sliding of the pawl 51 along the special-shaped limiting rail 4, the rotating clamp 52 and the limiting groove 43 maintain intermittent clamping cooperation. When the movable seat 6 stops, the rotating clamp 52 and the limiting groove 43 are clamped, so that the position of the limiting member 5 is fixed.
[0045] As another embodiment further provided by the present invention, the inner wall of the limiting groove 43 on one side along the window opening direction of the window sash 1 is a guide slope 41 , and the inner wall on the other side opposite thereto is a retention slope 42 .
[0046] Specifically, when the moving seat 6 slides along the window opening direction, it drives the limiter 5 to move on the special-shaped limiter rail 4. The rotating clamp 52 is always kept in a clockwise rotation trend by the elastic force of the torsion spring. At this time, the rotating clamp 52 first slides with the guide slope 41, turns slightly counterclockwise along the guide slope 41 and makes the torsion spring accumulate force. After the rotating clamp 52 is separated from the guide slope 41, the torsion spring potential energy is released, and the rotating clamp 52 rotates clockwise to the retention slope 42. When the rotating shaft of the roller 3 abuts against the pawl 51, the pawl 51 is forced to rotate counterclockwise, so that the rotating clamp 52 abuts against the retention slope 42, and the limiter 5 is fixed at this time.
[0047] As another embodiment further provided by the present invention, a blocking portion 44 is provided on the first end of the special-shaped limit rail 4 and is arranged at a termination position along the window opening direction of the window sash 1 . The blocking portion 44 is in sliding cooperation with the rotating clamp 52 .
[0048] Specifically, both sides of the blocking portion 44 are equipped with blocks for blocking the moving seat 6. When the limiting member 5 reaches the blocking portion 44, the side surface of the blocking portion 44 guides the rotating clamp 52 to make the rotating clamp 52 rotate 90 degrees counterclockwise, thereby driving the pawl 51 fixedly arranged with the rotating clamp 52 to rotate counterclockwise to the position as shown in FIG. Figure 4 In the state shown, the pawl 51 does not block the roller 3.
[0049] As another embodiment further provided by the present invention, the side wall of the ring 53 is in sliding connection with the clamping member 7 rotatably arranged on the movable seat 6 .
[0050] Specifically, the special-shaped limit rail 4 is as follows Figure 6 The initial position shown is provided with an arc-shaped blocking portion. During the unidirectional sliding of the pawl 51 along the special-shaped limiting rail 4, the rotating clamp 52 maintains intermittent clamping cooperation with the limiting groove 43, so that the circular ring 53 fixedly arranged on the rotating shaft of the pawl 51 rotates. At this time, the rotation amplitude of the circular ring 53 does not exceed 80 degrees, so that the clamp 7 always slides along the side wall of the circular ring 53. When the moving seat 6 drives the limiting member 5 to move to the blocking portion 44, the rotating clamp 52 is caused to rotate 90 degrees counterclockwise by the guiding effect of the blocking portion 44. At this time, the clamp 7 is clamped with the clamping groove 54 opened on the side wall of the circular ring 53, so that the circular ring 53 no longer rotates, so that the pawl 51 and the rotating clamp 52 are maintained as shown in the figure. Figure 4 In the state shown in FIG. 1 , the sliding movable seat 6 will not change the angle of the limit member 5. When the movable seat 6 slides in the opposite direction of the window opening direction to the special-shaped limit rail 4 as shown in FIG. Figure 6 In the initial position shown, the rotating clamp 52 slides with the inner wall of the arc-shaped blocking portion, so that the clamp 7 escapes from the clamping groove 54. After losing the restriction of the clamp 7, the ring 53 rotates clockwise under the elastic force of the torsion spring, driving the pawl 51 and the rotating clamp 52 to rotate clockwise, and the rotating clamp 52 falls into the limiting groove 43 again.
[0051] As another embodiment further provided by the present invention, the movable seat 6 is provided with a blocking member 61 which is pushed by a paddle 62 to maintain intermittent plug-in cooperation with a plurality of speed limiting grooves 21 provided on the special-shaped limiting rail 4 .
[0052] Specifically, during the sliding of the movable seat 6, the blocking member 61 is pushed by the paddle 62, causing the blocking member 61 to enter the speed limiting groove 21. Due to the large sliding force, the speed limiting groove 21 generates a reverse force on the blocking member 61, causing the blocking member 61 to be squeezed out again. This process slows down the movement speed of the movable seat 6, preventing the movable seat 6 from sliding too fast and causing the rotating clamp 52 to contact the guide slope 41 too quickly, resulting in an excessive rotation amplitude of the rotating clamp 52.
[0053] As another embodiment further provided by the present invention, a ratchet 31 is fixedly provided on the rolling shaft of the roller 3, and the ratchet 31 and the pawl 51 form a snap fit.
[0054] Specifically, after the user slides the movable seat 6 to the predetermined position, the position of the limit member 5 is fixed. At this time, pushing and pulling the window sash 1 drives the roller 3 to rotate, thereby driving the ratchet 31 to rotate. When the roller 3 reaches the movable seat 6, the ratchet 31 engages with the pawl 51, so that the window sash 1 can no longer slide in the window opening direction, thereby playing a role in limiting the width.
[0055] Working principle: The user Figure 2 In the window opening direction shown, the movable seat 6 is slid along the special-shaped limit rail 4 until it stops at a predetermined width. The movable seat 6 drives the pawl 51 and the rotating clamp 52 to move on the special-shaped limit rail 4. Since the torsion spring is arranged on the rotating shaft of the pawl 51, the rotating clamp 52 always maintains a clockwise rotation trend. Figure 2 The sliding seat 6 in the window opening direction is shown. During the unidirectional sliding of the pawl 51 along the special-shaped limit rail 4, the rotating clamp 52 maintains intermittent clamping cooperation with the limiting groove 43. At this time, the rotating clamp 52 first slides with the guide slope 41, flips slightly counterclockwise along the guide slope 41 and allows the torsion spring to accumulate force. After the rotating clamp 52 is separated from the guide slope 41, the torsion spring potential energy is released, and the rotating clamp 52 rotates clockwise to the retention slope 42. At this time, the rotation amplitude of the ring 53 does not exceed 80 degrees, so that the clamp 7 always slides along the side wall of the ring 53. When the moving seat 6 stops, the rotating clamp 52 is clamped with the limiting groove 43, so that the position of the limit member 5 is fixed. At this time, when the window sash 1 is pushed and pulled, the roller 3 is driven to rotate, thereby driving the ratchet 31 to rotate. When the roller 3 reaches the moving seat 6, the ratchet 31 is engaged with the pawl 51, so that the window sash 1 can no longer slide in the window opening direction, thereby playing a role in limiting the width. When the width limitation needs to be released, the unidirectional sliding moving seat 6 is moved to the blocking portion 44, and the side surface of the blocking portion 44 guides the rotating clamp 52 to make the rotating clamp 52 rotate 90 degrees counterclockwise, thereby driving the pawl 51 fixed with the rotating clamp 52 to rotate counterclockwise to as far as Figure 4 In the state shown in FIG. 1 , the pawl 51 does not block the roller 3. At the same time, the clamping member 7 is clamped with the clamping groove 54 on the side wall of the ring 53, so that the ring 53 does not rotate, thereby keeping the pawl 51 and the rotating clamping member 52 in the state shown in FIG. Figure 4 In the state shown in FIG. 1 , the sliding movable seat 6 will not change the angle of the limiting member 5, and the movable seat 6 can be restored to the state shown in FIG. Figure 6 In the initial position shown, the rotating clamp 52 slides with the inner wall of the arc-shaped blocking portion, so that the clamp 7 escapes from the clamping groove 54. After losing the restriction of the clamp 7, the ring 53 rotates clockwise under the elastic force of the torsion spring, driving the pawl 51 and the rotating clamp 52 to rotate clockwise, and the rotating clamp 52 falls into the limiting groove 43 again.
[0056] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
