[0022] The driving wheel structure includes a cover plate 4, a core shaft 5, a spring 6, a top block 7, a flange sleeve 9, a sliding sleeve 10, a sprocket 11 and a bearing 12; wherein the main structure of the driving wheel structure is the flange sleeve 9, the flange sleeve 9 is welded by a sleeve 91, a rear plate 92, a connecting sleeve 93 and a front plate 94, the part of the shaft 3 not connected to the support 2 is installed in the sleeve 91 through the bearing 12, and the flange sleeve 9 can rotate with the shaft 3 as the axis through the bearing 12;

[0023] In this embodiment, a front plate 94 and a rear plate 92 are welded on the outer peripheral side wall of the sleeve 91, wherein the front plate 94 is welded on the outer peripheral side wall of the second end portion of the sleeve 91 away from the lower surface of the base 1, and the rear plate 92 is welded on the outer peripheral side wall of the sleeve 91 close to the lower surface of the base 1, and the rear plate 92 is at a certain distance from the lower surface of the base 1, and a connecting sleeve 93 is welded between the rear plate 92 and the front plate 94, and the number of the connecting sleeves 93 is four, two of which are provided with sliding sleeves 10 inside, and the outer peripheral wall of the sliding sleeve 10 is in contact with the inner peripheral wall of the connecting sleeve 93, and the sliding sleeve 10 can ensure smooth extension and retraction of the top block 7 and the spring 6; the two sliding sleeves 10 are provided with a top block 7, and the top block 7 is a nail shape composed of a first part and a second part, which is wide at the top and narrow at the bottom; the rear plate 92 is located between the two connecting sleeves provided with the sliding sleeves 10 A cover plate 4 is provided above 93, and a spring 6 is provided between the top block 7 and the cover plate 4. The spring 6 is fixed in position by a core shaft 5, and the core shaft 5 is provided with a thread, which is connected to the cover plate 4 by a threaded connection; a through hole is opened at the position corresponding to the top block 7 provided on the front plate 94, and the second part of the top block 7 can pass through the through hole on the front plate 94 and be inserted into the positioning hole of the guide car 8, and when the second part of the top block 7 can pass through the through hole on the front plate 94, the first part of the top block 7 located in the sliding sleeve 10 can be stuck on the front plate 94 to prevent the top block 7 from falling off; a sprocket 11 is provided on the outer side of the two cover plates 4 on the rear plate 92, and the sprocket 11 is connected to the motor through a chain, and the sprocket 11 is driven to rotate by the rotation of the motor, and then the cloth roll is driven to rotate through the top block 7 inserted in the positioning hole on the guide car 8, and the cover plate 4 and the sprocket 11 do not interfere with each other.

[0025] In this embodiment, a groove is downwardly provided at the first end of the first part of the top block 7 that contacts the spring 6, and the spring 6 can be placed in the groove. The depth of the groove at the first end of the first part of the top block 7 is greater than or equal to the length of the core shaft 5. When the bottom of the top block 7 receives pressure to make the top block 7 slide upward, the core shaft 5 can be inserted into the groove, which will not affect the top block 7 from completely moving into the sliding sleeve 10, thereby preventing the top block 7 from being completely separated from the positioning hole of the guide opening 8.

[0026] The specific working process and working principle are as follows:

[0027] When the utility model is in use, the guide car 8 is moved to the bottom of the driving wheel structure. When the protruding part of the top block 7 is not aligned with the hole on the guide car 8, the top block 7 is squeezed, and the spring 6 is compressed. Then the driving wheel structure rotates to adjust the position, so that the top block 7 is aligned with the positioning hole on the guide car 8. At this time, the top block 7 is pushed out by the spring 6, and the second part of the top block 7 is inserted into the positioning hole on the guide car 8, so that the driving wheel structure is fixedly connected to the guide car 8. Then, the sprocket 11 is rotated by the rotation of the motor, and then the driving wheel structure rotates, and the guide car roll cloth roll is driven to rotate through the top block 7. The structure is compact and simple, and the difficulty of processing and assembly is low. The split structure reduces the amount of raw materials used, the amount of frames is reduced, and the cost is greatly reduced.

[0028] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present technical content. As long as these changes do not deviate from the concept of the present invention, they all fall within the scope of protection of this patent.
