[0005] In order to solve the above problems, the technical solution of the utility model is: a positioning device for an electric window opener, comprising a base, a protective shell detachably installed on the top of the base, a fixing groove is opened at the center of the top surface of the base, a central shaft is rotatably installed inside the fixing groove, a worm gear is installed on the outside of the central shaft, a supporting plate is fixedly connected to the top, positioning frames are detachably installed on the top of both ends of the supporting plate, a worm gear meshing with the worm gear is rotatably installed on one side of the central shaft inside the fixing groove, and a knob is installed on one end of the worm gear.

[0006] Furthermore, four positioning columns are fixedly connected to the top of the base, and a threaded hole for installing screws is opened in the middle of the positioning columns. The four positioning columns are respectively located at the four corners inside the protective shell, and through holes corresponding to the positions of the threaded holes are opened at the four corners of the top surface of the protective shell.

[0007] Furthermore, mounting holes are provided at the four corners of the base, an operation port is provided on the top surface of the protective shell, and heat dissipation holes are provided on the side surfaces.

[0008] Furthermore, fixing plates are installed at both ends of the supporting plate on the top of the base, the thickness of the fixing plates is the same as the thickness of the supporting plate, and a gap is provided between the fixing plates and the supporting plate.

[0009] Furthermore, the positioning frame is an inverted U-shaped frame and is mounted on the supporting plate by bolts.

[0010] Furthermore, a groove is formed on the front end surface of the base, and the knob is located inside the groove.

[0011] The advantages of the utility model compared with the existing technology are: the electric window opener of the utility model is installed on the supporting plate through the positioning frame, the base is installed on the frame of the window, the worm is rotated by the knob, and the worm drives the central axis and the supporting plate to rotate through the worm gear, so that the installation angle of the electric window opener can be fine-tuned without adjusting the base, avoiding leaving extra holes on the frame of the window, and at the same time, the installation angle of the electric window opener can be adjusted by turning the knob, which is simple and convenient.

[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0018] like Figures 1 to 3 As shown, a positioning device for an electric window opener comprises a base 1, a protective shell 2 is detachably mounted on the top of the base 1, four positioning posts 9 are fixedly connected to the top of the base 1, threaded holes for mounting screws are provided in the middle of the positioning posts 9, the four positioning posts 9 are respectively located at the four corners inside the protective shell 2, through holes corresponding to the positions of the threaded holes are provided at the four corners of the top surface of the protective shell 2, mounting holes are provided at the four corners of the base 1, an operating port is provided on the top surface of the protective shell 2, and heat dissipation holes are provided on the side.

[0019] The protective shell 2 can be mounted on the positioning column 9 by screws to achieve the connection between the base 1 and the protective shell 2 .

[0020] like Figure 2 , Figure 3 and Figure 4As shown, a fixing groove is provided at the center of the top surface of the base 1, and a central axis 3 is rotatably installed inside the fixing groove, a worm gear 4 is installed on the outside of the central axis 3, and a supporting plate 5 is fixedly connected to the top. A fixing plate 10 is installed at both ends of the supporting plate 5 on the top of the base 1. The thickness of the fixing plate 10 is the same as that of the supporting plate 5, and a gap is provided between the fixing plate 10 and the supporting plate 5. A positioning frame 6 is detachably installed on the top of both ends of the supporting plate 5. The positioning frame 6 is an inverted U-shaped frame and is installed on the supporting plate 5 by bolts.
