FIG. 1 is a schematic diagram of a supporting rocker arm mechanism 100 according to an embodiment of the present invention; fig. 2 is an exploded view of the supporting rocker arm mechanism 100 shown in fig. 1. As shown in fig. 1 and 2, a supporting rocker arm mechanism 100 according to an embodiment of the present invention includes a first link 130, a base 110, and a positioning rod 120; the base 110 is used for connecting with the bottom of the window sash, and the first connecting rod 130 is used for connecting with the window frame; the base 110 is configured with a first sliding chute 111, and the first connecting rod 130 is slidably connected to a groove wall of the first sliding chute 111 through a positioning rod 120; a second sliding groove is formed on the base 110, the second sliding groove comprises an entering channel 1121, a clamping channel 1122 and an exiting channel 1123, the entering channel, the clamping channel 1122 and the exiting channel 1123 form a closed loop, and the depth of the depressions of the three in the transition region increases progressively along the first direction; when the second end of the positioning rod 120 moves to the end of the entry channel 1121, the first link 130 deflects inward by a predetermined angle relative to the base 110, so that the second end of the positioning rod 120 moves to the fastening channel 1122 along the first direction; when the second end moves to the latching channel 1122, the first link 130 deflects outward by a predetermined angle relative to the base 110, so that the second end of the positioning rod 120 moves to the head end of the exit channel 1123 along the first direction.

As shown in fig. 2, a first direction is indicated by an arrow in the second sliding chute, the first direction is approximately counterclockwise, and the recessed depths of the entering channel 1121, the blocking channel 1122 and the exiting channel 1123 in the transition region are sequentially increased along the counterclockwise direction, so that the three channels form a step in the transition region. When the window sash is in a locked state, the position of the positioning rod 120 is an initial position (i.e., the leftmost end of the second sliding groove).

As shown in fig. 4, to illustrate the opening of the supporting rocker arm, during the process of opening the window from locking, the first link 130 is deflected outward (i.e., the angle between the two is gradually increased) relative to the base 110, so that the end of the first link 130 connected to the base 110 moves to the right. Since the first end of the positioning rod 120 (i.e., the left end of the positioning rod 120) is connected to the first link 130 through the first connection member 171, the first link 130 moves to drive the positioning rod 120 to move rightward, and since a step is formed between the entrance channel 1121 and the exit channel 1123 to limit the positioning rod 120 from moving reversely from the entrance channel 1121 to the exit channel 1123, the positioning rod 120 can only move counterclockwise in the entrance channel 1121, i.e., the second end of the positioning rod 120 (i.e., the right end of the positioning rod 120) slides from the initial position to the end of the entrance channel 1121. At this time, when the window sash is pulled to reduce the opening amplitude of the window sash, so that the first connecting rod 130 deflects inward by a preset angle relative to the base 110, the positioning rod 120 is blocked from moving clockwise in the entering channel 1121 due to the step arranged at the position of the entering channel 1121 close to the end of the entering channel itself; since the recess depth of the locking channel 1122 relative to the end of the entering channel 1121 is increased, the right end of the positioning rod 120 moves from the end of the entering channel 1121 to the locking channel 1122. Under the condition that no external force pushes the window sash outwards, under the action of gravity of the window sash, the positioning rod 120 is pressed on the clamping channel 1122 and cannot slide easily, so that the window sash is positioned to the current opening angle and cannot be closed accidentally, as shown in fig. 5, the schematic diagram of the positioning process of the support rocker arm mechanism is shown. The predetermined angle is a deflection angle of the positioning rod 120 sliding from the end of the access channel 1121 to the first link 130 corresponding to the latching channel 1122.

Fig. 6 is a schematic view of the supporting rocker arm mechanism 100 shown in fig. 5 during an unlocking process. As shown in fig. 6, when the positioning state needs to be released, the window sash is pushed to increase the opening range, the first link 130 deflects outward by a predetermined angle relative to the base 110, and drives the positioning rod 120 to move upward and rightward, and since the recess depths of the entry channel 1121 and the latching channel 1122 in the transition region are sequentially increased, the positioning rod 120 is blocked from moving from the latching channel 1122 to the entry channel 1121, so that it moves to the head end of the exit channel 1123 with the increased recess depth. In this state, the window sash is pushed to make the first connecting rod 130 deflect inwards relative to the base 110, and the left end of the positioning rod 120 is driven to move leftwards; since the head end of the exit channel 1123 and the clipping channel 1122 form a step, the movement of the positioning rod 120 from the exit channel 1123 to the clipping channel 1122 is limited, and the positioning rod 120 can only move in the exit channel 1123, so that the positioning rod 120 moves from the head end of the exit channel 1123 to the tail end of the exit channel 1123 and moves to the initial position, and the locking of the window sash is further achieved, as shown in the schematic diagram of fig. 7, in which the supporting rocker arm mechanism 100 is in the closing process. Through the sliding fit of the positioning rod 120 and the second sliding groove, the transition area is provided with a step to limit the moving direction of the positioning rod 120, so that the positioning rod can only move along a preset track to position the window sash to the clamping position. Under the condition that the window sash is not pushed outwards, the positioning rod 120 cannot move, so that the firmness of clamping the window sash by the supporting rocker arm mechanism 100 is improved, and the use reliability of the window sash is further improved.

By arranging the entry channel 1121 and the exit channel 1123 on both sides of the core-shaped block 112, the window sash is opened from locking, and opened to closing, the movement strokes of the positioning rod 120 are opposite, the movement distances are consistent, and the positioning rod 120 can return to the initial position through the exit channel 1123, so that the window sash can be switched between the open state and the locked state. The clamping channel 1122 is connected to the concave point position of the heart-shaped block 112, a groove is formed in the concave point position of the heart-shaped block 112, and the clamping channel is formed through the groove, so that when the positioning rod 120 moves to the current position, the groove limits the movement of the positioning rod 120, and then the positioning is performed to the current opening angle, and the positioning effect is guaranteed. In other embodiments, the base is configured with a triangular block, the entering channel, the clamping channel and the exiting channel are arranged around the circumference of the triangular block, the clamping channel is connected to one side opposite to the vertex of the triangular block, and the position of the clamping channel is aligned with the vertex of the triangular block along the length direction of the base.

In one embodiment, the recessed depth of the access channel 1121 is gradually decreased from the head end to the tail end, that is, when the access channel 1121 of fig. 2 is placed to the viewing angle of fig. 3, the bottom wall of the access channel 1121 extends obliquely upward from the head end to the tail end. By arranging the recessed depth of the entering channel 1121 in the counterclockwise direction to decrease progressively, the difference of the recessed depth between the tail end of the exiting channel 1123 and the head end of the entering channel 1121 is made up, and when the second chute extends to the exiting channel 1123, the recessed depth of the tail end of the exiting channel 1123 is smaller than the head end of the entering channel 1121, so that the positioning rod 120 is ensured to move along the preset track. Further, in the counterclockwise direction, the recessed depth of the exit channel 1123 may also be set to decrease in sequence, and at this time, the inclination of the entry channel 1121 may decrease correspondingly.

Fig. 3 is a schematic view of the positioning rod 120 shown in fig. 2. In an alternative embodiment, as shown in fig. 3, a side of the positioning rod 120 facing the base 110 is configured with a latch shaft 121, and the positioning rod 120 moves between the entering channel 1121, the latch channel 1122 and the exiting channel 1123 through the cooperation of the latch shaft 121 and the second sliding slot, so as to realize the process from locking to opening of the window sash and the process from opening to locking.
