DETAILED DESCRIPTION

[0019] A specific implementation of the present utility model is described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present utility model is not limited by the specific implementation mode.

[0020] Embodiment 1:

[0021] like Figure 1-4 As shown, a handle opening and closing mechanism for a window sash comprises a handle 1 arranged on one side of the window sash 6 and a rotating transmission assembly, which is specifically arranged at the left-right symmetrical center of the window sash 6. The rotating transmission assembly comprises reciprocating transmission assemblies on both sides and a rotating connecting rod 21. The reciprocating transmission assemblies on both sides comprise upper and lower transmission connecting members 22, and the upper and lower locking points of the window sash 6 are driven to open and close through the two transmission connecting members 22.

[0022] Specifically, the reciprocating transmission assembly is an eccentric connecting rod assembly, which includes an eccentric wheel 23, which is connected to the rotating connecting rod 21 and driven to rotate. The two ends of the rotating connecting rod 21 are respectively provided with a sleeve assembly 31, and the sleeve assembly 31 is arranged on a fixed block 32. The fixed block 32 is fixed on the window sash 6. The eccentric wheel 23 has two eccentric connecting ends, which are respectively hingedly connected to two transmission connecting members 22. The transmission connecting member 22 is a transmission connecting arm, which is connected to the pull rod 5, and the locking point is driven to move through the pull rod 5.

[0023] In some embodiments, the handle 1 is rotatably connected to the handle base 4 and is fixed to the window sash 6 through the handle base 4 .

[0024] In some embodiments, the handle 1 is a U-shaped handle, and a rotating connecting rod 21 is connected to the U-shaped handle. There can also be two handles 1, which respectively drive the reciprocating transmission components on both sides. In this embodiment, one handle 1 is set, which has better synchronization and is convenient for operation.

[0025] In some embodiments, the handle base 4 is provided with an embedded groove 41 that matches the handle 1. The handle 1 is rotated and embedded in the embedded groove 41. When the handle 1 is idle, the handle 1 can be embedded in the embedded groove 41, which is more beautiful and will not cause any obstruction to the surroundings.

[0026] In some embodiments, a horizontal stopper 44 is provided on the handle seat 4, and the horizontal stopper 44 stops the handle 1 horizontally, that is, when the handle 1 is rotated upward, it can only be rotated to a horizontal position, which is convenient for horizontal pushing and pulling of the handle 1, so that the force on the window sash 6 is relatively balanced. The rotating connecting rod 21 is a square rod, and a rotating hole 42 is provided on the handle seat 4. The square rod extends outward from the rotating hole 42, and a U-shaped stopper slot 43 is provided on the handle seat 4. Both sides of the U-shaped handle are provided with sliding holes 11. The square rod reciprocates along the sliding holes 11, and the inner side end of the U-shaped handle is pushed into or out of the U-shaped stopper slot 43 through reciprocating sliding;

[0027] When the handle 1 is in the embedded groove 41, the locking point of the window sash 6 is in a locked state, and the handle 1 is turned upward to a horizontal position (rotated 90 degrees). At this time, the locking point of the window sash 6 is in an open and closed state. At this time, the handle 1 can be pulled to pull the window sash 6 to the opening side to open it. The window sash 6 is opened in a translational sliding manner, and ventilation is provided through the gaps around it. After opening the window sash 6, the handle 1 can be returned to its original position; when the window sash 6 needs to be closed, the handle 1 is turned upward to a horizontal position, and the handle 1 is pushed inward to drive the window sash 6 to return to its original position. Since the handle 1 is in a horizontal position, the horizontal push can make the force on the window sash 6 more balanced, and the movement of the window sash 6 is smoother. In addition, due to the cooperation between the inner side of the handle seat 4 and the U-shaped limit slot 43, the contact area is larger, which makes the force more balanced and also reduces the force on the rotating connecting rod 21 during the pushing process.

[0028] The above disclosures are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
