Moreover, the top end of the rotating shaft 43 passes through the pulley seat 41, the inner side of the housing 12 is provided with a limiting groove 122, and the rotating shaft 43 is longitudinally slidably disposed in the limiting groove 122.

Two extension plates 16 are fixedly arranged on two sides of the housing 12, two lifting micro switches 5 are fixedly arranged on the extension plates 16 on the two sides and are positioned on two sides of the winding wheel 22, and when the lifting micro switches 5 are triggered, the motor assembly 8 stops acting to limit the transverse displacement of the winding wheel 22 so as to control the lifting height of the pull rope 9; the two sides of the extension plate 16 are transversely provided with waist-shaped holes 161, the extension plate 16 is suitable for being fixed on the base 1 by fasteners passing through the waist-shaped holes 161, and the fixing position of the extension plate 16 on the base 1 can be transversely adjusted by the waist-shaped holes 161. A plurality of wire clamps 123 are arranged on the housing 12, and the wire clamps 123 are arranged from the lifting microswitch 5 to the control box 7.

The control box 7 comprises a bottom box 71, a circuit board 72 and a shielding cover 73, wherein the bottom box 71 is fixedly arranged on the base 1, the circuit board 72 is fixedly arranged in the bottom box 71, the shielding cover 73 covers the circuit board 72, and the shielding cover 73 has an electromagnetic shielding function. The control box 7 is electrically connected with the motor assembly 8 and is suitable for controlling the motor assembly 8 to act. The circuit board 72 is provided with a reed switch 62, and the permanent magnet 61 and the reed switch 62 form a magnetic control switch 6. When the pull rope 9 is stressed to penetrate through the pulley assembly 4, the pulley assembly 4 slides away from the control box 7; when the pull rope 9 loses force, the pressure spring 10 pushes the pulley component 4 to approach the control box 7, the permanent magnet 61 touches the reed switch 62, the magnetic control switch 6 is triggered, and the motor assembly 8 stops acting. The base 1 is provided with a notch 17, the notch 17 is located below the control box 7, the profile of the notch 17 is the same as that of the speed reduction cover 84, namely, a plate cut by the notch 17 is processed to form the speed reduction cover 84, and the manufacturing cost is further reduced.

It should be noted that the specific structure and operation principle of the magnetic switch 6 are well known to those skilled in the art, and therefore are not specifically described in the present embodiment, but this does not prevent the magnetic switch from being an implicit technical feature of the present application.

As shown in fig. 12 to 14, the motor assembly 8 of the present embodiment is fixedly disposed on the base 1, and includes a motor body 8a and a reduction box 8b, the motor body 8a includes a motor housing 81 and a motor cover 82, the reduction box 8b includes a reduction housing 83 and a reduction cover 84, a mounting leg 833 extends from the reduction housing 83, and the mounting leg 833 is adapted to pass through a fastener to fix the motor assembly on the base 1.

Specifically, the motor cover 82 and the reduction housing 83 are integrally formed; the motor body 8a is provided with a motor shaft 85, the motor shaft 85 passes through the motor cover 82 and enters the speed reduction housing 83, a worm section 861 extends out of the front end of the motor shaft 85, a worm wheel 862 is rotatably arranged in the speed reduction housing 83, a first gear 863 is concentrically fixed on the worm wheel 862, a second gear 864 is also rotatably arranged in the speed reduction housing 83, and the output shaft 87 is concentrically fixed on the second gear 864; the worm section 861 meshes with the worm gear 862, and the first gear 863 meshes with the second gear 864. Wherein the worm section 861, the worm wheel 862, the first gear 863 and the second gear 864 constitute the speed reduction assembly 86, implementing the speed reduction function. In this embodiment, the mounting plate 88 is integrally formed on the reduction cover 84.

It should be noted that the fastener of the present embodiment is a general-purpose component such as a fastening bolt, a self-tapping screw, and the like, and therefore, is not completely shown in the drawings, but this does not prevent the fastener from becoming an implicit technical feature of the present application.

The foregoing has described the general principles, essential features, and advantages of the application. It will be understood by those skilled in the art that the present application is not limited to the embodiments described above, which are merely illustrative of the principles of the application, but that various changes and modifications may be made without departing from the spirit and scope of the application, and these changes and modifications are intended to be within the scope of the application as claimed.
