[0002] Patent document CN220319361U discloses a split-type window crank and a replaceable housing. The split-type window crank disclosed in this utility model includes: a transmission assembly; a lifting arm connected to the transmission assembly, the transmission assembly driving the lifting arm to move; and a protective assembly disposed on the transmission assembly for protecting the transmission assembly. The replaceable housing disclosed in this utility model is disposed on the aforementioned split-type window crank. This utility model can improve the assembly accuracy of the window crank, facilitate disassembly, reduce maintenance costs, and the replaceable housing allows for further changes in various colors and surface treatments of the housing, making it more economical to suit different colored doors and windows, and protecting the window crank from damage, thus extending its service life. In this patent, the handle is irregularly shaped, and the housing has a groove for placing the handle. The handle is either left or right, which limits its versatility, makes it difficult to manufacture, and results in a relatively heavy weight. Summary of the Invention

[0007] The handle is hinged to the other end of the rocker arm. Folding the rocker arm allows the handle to be placed into the triangular groove.

[0008] Furthermore, the handle is a cuboid.

[0009] Furthermore, the outer casing is coated with a layer of anti-rust paint.

[0010] Furthermore, the rocker arm is coated with a layer of anti-rust paint.

[0011] Furthermore, the handle is coated with a layer of anti-rust paint.

[0012] Furthermore, the rocker arm can rotate at an angle of 0~135° around the hinge point with the rotating seat.

[0013] Furthermore, the bottom of the triangular groove slopes inward.

[0014] The window crank according to the present invention has a lightweight crank arm that is simple to manufacture and low in cost; it is versatile and can be used on both left and right sides; and it has a long service life.

[0015] It should be understood that both the foregoing general description and the following detailed description are exemplary and intended to provide further illustration of the claimed technology. Attached Figure Description

[0021] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0022] First, combine Figures 1-5 The window crank according to an embodiment of the present invention is used for opening and closing windows and has a wide range of applications.

[0023] like Figures 1-5 As shown, the window crank of this utility model embodiment includes a transmission assembly, which includes a worm gear, a worm, and a crank shaft; it also includes:

[0024] The outer casing 1 has a first hinge hole 11 at one end and a triangular groove 12 at the other end.

[0025] Rotary seat 2 is connected to the crank shaft. Rotating the rotary seat 2 can drive the crank shaft to rotate. One end of the crank shaft connected to the rotary seat 2 is located in the first hinge hole 11.

[0026] The rocker arm 3 is hinged to the rotating seat 2 at one end. The rocker arm 3 is a cuboid and has a cavity 31. The rotating seat 2 is placed inside the cavity 31. The cavity 31 reduces the weight of the rocker arm 3 and allows the rotating seat 2 to be stored inside the cavity 31, which greatly improves the aesthetics of the product.

[0027] The handle 4 is hinged to the other end of the rocker arm 3 and can rotate relative to the rocker arm 3; folding the rocker arm 3 allows the handle 4 to be placed into the triangular groove 12, which is used to limit the position of the handle 4 and the rocker arm 3.

[0028] Furthermore, such as Figures 1-3 As shown, in this embodiment, the handle 4 is a cuboid, which has strong versatility.

[0029] Furthermore, in this embodiment, the outer casing 1 is coated with a layer of anti-rust paint to prevent rusting, thereby improving the product's service life.

[0030] Furthermore, in this embodiment, the rocker arm 3 is coated with a layer of anti-rust paint to prevent rusting and thus improve the product's service life.

[0031] Furthermore, in this embodiment, the handle 4 is coated with a layer of anti-rust paint to prevent rusting and thus improve the product's service life.

[0032] Furthermore, such as Figures 1-3 As shown, in this embodiment, the rocker arm 3 can rotate around the hinge point with the rotating seat 2 at an angle of 0~135°. In the initial state, the rocker arm 3 is parallel to the outer shell 1, and the handle 4 is placed in the triangular groove 12. When it is necessary to shake the rocker arm 3 to drive the crank shaft, it is easier to shake the rocker arm 3 by opening it 135° relative to the outer shell 1.

[0033] Furthermore, such as Figure 1 As shown, in this embodiment, the bottom of the triangular groove 12 is inclined inward to prevent the handle 4 from disengaging from the triangular groove 12.

[0034] Above, refer to Figures 1-5 The present invention describes a window cranker according to an embodiment of the present invention. The crank arm 3 is lightweight, simple to manufacture, and low in cost; it is versatile and can be used on both left and right sides; and it has a long service life.
