[0023] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] Embodiment 1

[0025] As Figure 1 , Figure 2 , Figure 3 shown, in this example, the window opener includes a fixed seat 2, a housing 1, and a screw telescopic assembly 5 and a bevel gear transmission mechanism 6 installed in the cavity of the housing 1. The end of the housing 1 is hinged to the fixed seat 2 to dock the fixed seat 2 with a window sill or other fixed rods, fixed brackets, etc.

[0026] In this example, the configuration of the fixed seat is improved. As Figure 3 shown, the fixed seat 2 includes a connected upper part 21 and a lower part 22. The upper part 21 and the lower part 22 are integrally injection molded. The angle ( Figure 3 shown as a) between the upper part 21 and the lower part 22 is between 0 - 180°. The overall fixed seat is basically in an L-shaped configuration. The end of the housing 1 is hinged to the lower part 21. The value of the angle a can be, for example, 140°, 150°, 60°, 30°, etc. The preferred value range is: 20 - 160°. For the number of fixed seats, if a single fixed seat is hinged at the end of the housing, preferably as Figure 1 , Figure 2 shown, two fixed seats 2 are relatively hinged at the end of the housing 1 to improve stability.

[0027] For convenient docking and installation, in this example, a mounting hole 24 is formed at the end of the upper part 21. The mounting hole 24 is, for example, a rectangular hole to facilitate plug-in installation with a rectangular rod. To facilitate adaptation to rectangular rods of different sizes, in this example, the upper part 21 is in a ring shape. The threaded fastener 23 is, for example, a bolt, and a threaded hole is formed on the ring wall. The bolt is screwed into the threaded hole on one side of the ring wall and connected to the threaded hole on the opposite side of the ring wall. The bolt and one side of the ring cavity enclose the mounting hole 24. The distance between the two ring walls can be adjusted by the bolt to change the size of the mounting hole, thereby adapting to rectangular rods of different sizes.

[0028] For the convenience of docking with the housing, in this example, a round hole, namely the hinge hole 25, is formed at the end of the lower part 22. Specifically, as shown in the figure, the housing 1 includes a cylinder 10 and a connecting seat 11. The connecting seat 11 is fixed at the head end of the cylinder 10. A convex column 111 is integrally formed at the opposite side of the head end of the connecting seat 11. The lower part 22 is directly sleeved on the convex column 111 through the hinge hole 25, and the housing 1 can rotate relative to the lower part.

[0029] As shown in Figure 1 , Figure 2 , Figure 4 the figure, in this example, a bevel gear transmission mechanism 6 is installed in the cavity of the connecting seat 11. The bevel gear transmission mechanism 6 consists of two meshing bevel gears 61. The two bevel gears are rotatably installed in the cavity of the connecting seat, such as rotatably connected through bearings, etc. One bevel gear 61 is connected to the screw telescopic assembly, and the other bevel gear is connected to an external driving mechanism, etc. The driving mechanism can be of various types such as manual type, electric type, etc.

[0030] For the convenience of docking the bevel gear transmission mechanism with the external driving mechanism and the same type of window opener, in this example, a connecting rod 4 is added. The connecting rod 4 is in the shape of a long rod and its two end parts are multi-faceted prismatic, such as hexagonal. The end part of the connecting rod 4 extends out from the convex column 111 (forming an outward convex structure). The other bevel gear 61 in the bevel gear transmission mechanism 6 is concentrically fixed on the connecting rod 4. When in use, if this window opener is installed at four adjacent windows in parallel, the connecting rods between the adjacent window openers are connected by a connecting rod, and the connecting rod of the window opener at the side is docked with the driving mechanism, then multiple groups of window openers can be synchronously driven by a single driving mechanism.

[0031] In this example, a screw telescopic assembly 5 is installed in the cavity of the cylinder 10 of the housing 1. The bevel gear transmission mechanism 6 is connected to the screw telescopic assembly 5. The rotation of the bevel gear synchronously drives the screw telescopic assembly to expand and contract. The structure of the screw telescopic assembly adopts a common structure: for example, it includes a matching screw barrel 52 and a screw 51. The screw barrel 52 is sleeved on the screw 51 and is in threaded engagement. One bevel gear 61 in the bevel gear transmission mechanism 6 is fixed to the end of the screw 51. The screw 51 is rotatably connected in the cavity of the cylinder 10 through bearings, etc. When the screw 51 rotates, the screw barrel 52 moves along the axial direction of the cylinder under guidance. For example, a guide block 53 is sleeved on the screw barrel 51, and the guide block 53 cooperates with the inner wall of the cavity of the cylinder 10 to guide the movement of the screw barrel. The end of the screw barrel 52 is fixed to the connecting piece 3 outside the housing 1. A through hole, namely the connecting hole, is formed at the end of the connecting piece 3 to be hinged to the mounting seat on the window glass, etc.

[0032] In this example, for the convenience of docking the connecting seat with the housing, the connecting seat adopts an upper and lower seat body configuration. The upper and lower seat bodies are fixed and clamped at the end of the cylinder by screws, bolts, etc. The upper and lower seat body configuration facilitates the installation of the internal bevel gear and the docking with the cylinder.

[0033] The above are only the preferred embodiments of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. Any technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements should also be regarded as within the protection scope of the present utility model.
