[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-6 The utility model provides a technical solution: a nano steel ball wheel for a curtain track, comprising a track wheel 1, a connecting groove 2 being provided at one end of the track wheel 1, a steel sheet 3 being embedded at one end of the connecting groove 2, a connecting hole 4 being provided on one side of the surface of the steel sheet 3, a first fixing groove 5 being provided on both sides of the inner ring of the steel sheet 3, a first spring 6 being welded at one end of the inner side of the first fixing groove 5, a splint 7 being welded at one end of the first spring 6, a protrusion 8 being provided on one side surface of the splint 7, a fixing hole 9 being provided on one end surface of the track wheel 1, a fixing bolt 10 being connected at one end of the fixing hole 9, spherical grooves 11 being provided on both side surfaces of the track wheel 1, a second fixing groove 12 being provided at one end of the spherical groove 11, a second spring 13 being welded at one end of the inner side of the second fixing groove 12, an extrusion block 14 being welded at one end of the second spring 13, a steel ball 15 being embedded at one end of the spherical groove 11, and a limiting hole 16 being provided on one side surface of the steel ball 15.

[0020] Furthermore, the steel sheet 3 is embedded in the inner side of one end of the track wheel 1, and the opening position of the steel sheet 3 corresponds to the through-hole position of the track wheel 1. Through the setting of the steel sheet 3, the steel sheet 3 is embedded in the connecting groove 2 and fixed, and then combined with the track wheel 1. First, the structure of the steel sheet 3 is stronger, and it will not increase the weight of the track wheel 1 much. At the same time, the steel sheet 3 can be used as the main force point after the curtain is hung, which can protect the plastic track wheel 1 and increase the service life of the track wheel 1.

[0021] Furthermore, one end of the fixing hole 9 is a threaded structure, the fixing bolt 10 is threadedly connected to the fixing hole 9, and one end of the fixing bolt 10 passes through the connecting hole 4. Through the setting of the fixing hole 9, the position of the fixing hole 9 just corresponds to the position of the connecting hole 4. When the fixing bolt 10 and the fixing hole 9 are locked, the steel sheet 3 will be fixed.

[0022] Furthermore, the splint 7 is an arc structure, and the protrusions 8 are distributed at equal intervals on the surface of the splint 7. Through the arrangement of the splint 7, when the curtain is hooked on one end of the track wheel 1 during use, the splint 7 can be contracted by the first spring 6 to tighten and reinforce the hook of the curtain to prevent it from falling off.

[0023] Furthermore, the steel ball 15 is connected to the extrusion block 14 through the limiting hole 16, and the steel ball 15 and the spherical groove 11 form a rotating structure. Through the setting of the steel ball 15, the steel ball 15 is smoother to use and rolls more smoothly. At the same time, the steel ball 15 is more wear-resistant.

[0024] Working principle: first, insert the steel sheet 3 from one end of the connecting groove 2, and make the positions of the connecting hole 4 and the fixing hole 9 correspond to each other. Then, rotate and screw the fixing bolt 10 at one end of the fixing hole 9 so that one end of the fixing bolt 10 can pass through the connecting hole 4 until the fixing hole 9 position at the other end. After the fixing bolt 10 is locked, fix the steel sheet 3, and then press the steel ball 15 into one end of the spherical groove 11. Then rotate the steel ball 15 so that the extrusion block 14 can be pushed by the second spring 13 to embed into the limiting hole 16 on the surface of the steel ball 15. Then install the track wheel 1 to one end of the curtain track, and then buckle the curtain to the opening of the track wheel 1 through the hook. At the same time, the splints 7 on both sides of the inner ring of the steel sheet 3 are tightened under the action of the first spring 6, and the hook connected to the curtain is tightened. Under the action of the protrusion 8, the friction force is increased, and finally the curtain is pulled. The track wheel 1 moves back and forth under the rolling of the steel ball 15.

[0025] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
