Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of clothes drying rack, in particular to a movable base of clothes drying rack. BACKGROUND

[0002] The existing folding clothes drying rack has a movable type or a fixed type. The fixed type clothes drying rack is generally supported by a plurality of rods or a two X-shaped base to make the clothes drying rack stand stably. However, when the clothes drying rack is stored and transported, the labor intensity is large and the use is inconvenient. The movable type clothes drying rack is generally provided with universal wheels at the bottom to make the clothes drying rack move conveniently. However, the cost of the universal wheels is high and the production cost of the clothes drying rack is additionally increased. Therefore, the movable base of the clothes drying rack is designed to switch the clothes drying rack between the fixed state and the movable state by adjusting different use states. SUMMARY

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work are within the protection scope of the present application.

[0029] Please refer to Figure 7 and 8The present invention provides a technical solution: a movable base of a clothes drying rack, comprising a support base connected to the bottom of the clothes drying rack, the support base comprising a ball sleeve 1 and a ball mounting seat 2, one end of the ball mounting seat 2 is plugged with the ball sleeve 1, and a large ball embedding groove 21 is provided on the surface of the ball mounting seat 2, the large ball embedding groove 21 is semicircular, and a large ball 3 is arranged in the large ball embedding groove 21, the large ball 3 is restricted in the large ball embedding groove 21 by the ball mounting seat 2, and a ball outlet 12 is provided on the top surface of the ball sleeve 1, and a part of the large ball 3 is exposed through the ball outlet 12. When the clothes drying rack is supported by the support base, the rolling of the large ball 3 can move the support base, further moving the position of the clothes drying rack. At the same time, the support base has a simple structure and low production cost.

[0030] In one embodiment, when there are many clothes hanging on the clothes drying rack and they are heavy, the pressure between the large ball 3 and the large ball groove 21 will increase, further increasing the friction between the large ball 3 and the large ball groove 21, making it difficult for the large ball 3 to rotate and causing jamming. Therefore, in this embodiment, small ball grooves 22 with central symmetrical distribution are opened on the inner surface of the large ball groove 21, and small balls 4 are arranged in the small ball grooves 22. The small balls 4 are tangent to the large balls 3. The contact between the small balls 4 and the large balls 3 is used to change the surface contact into point contact, thereby reducing the contact surface between the large ball groove 21 and the large balls 3, further reducing the friction, and making the large balls 3 roll more smoothly.

[0031] like Figures 1 to 5 As shown, in one embodiment, a thread 14 is formed on the outer surface of the ball sleeve 1, and a lifting cover 5 is connected to the outer surface of the ball sleeve 1 through the thread 14. The height of the lifting cover 5 can be adjusted by rotating the lifting cover 5. When the bottom surface of the lifting cover 5 is lower than the large ball 3, the lifting cover 5 supports the clothes drying rack, and the clothes drying rack cannot move. When the bottom surface of the lifting cover 5 is higher than the large ball 3, the large ball 3 supports the clothes drying rack, and the rolling of the large ball 3 can drive the clothes drying rack to move.

[0032] like Figure 6 As shown, the lifting cover 5 includes a screw sleeve 51 and an outer cover 52. A threaded groove is formed on the inner wall of the screw sleeve 51. The outer cover 52 is formed at the upper end of the screw sleeve 51. The outer cover 52 is conical. The conical outer cover 52 increases the contact area between the outer cover 52 and the ground, further enhancing the stability of the clothes drying rack.

[0033] A reinforcing rib 53 is formed between the outer cover 52 and the screw sleeve 51 . The reinforcing rib 53 enhances the rigidity of the lifting cover 5 and prevents the lifting cover 5 from being deformed or damaged under pressure.

[0034] like Figure 9As shown, in one embodiment, a pin hole 64 is opened on the surface of the ball sleeve 1 and the ball mounting seat 2, and the outer side of the support seat is rotatably connected to the base 6 through a pin. By rotating the base 6, the angle between the base 6 and the support seat can be adjusted. When the base 6 supports the clothes drying rack, the support seat and the base 6 are vertically distributed, and the clothes drying rack cannot move. When the support seat supports the clothes drying rack, the support seat and the base 6 are tilted, and the base 6 is in a vacant state. The rolling of the large ball 3 is used to drive the clothes drying rack to move.

[0035] like Figure 9 and 10 As shown, a guide groove 63 is provided on the inner wall of the bottom of the base 6. One end of the guide groove 63 is a round head formed in the center of the base 6. The guide groove 63 is formed from the edge of the base 6 to the center. The large ball 3 swings along the guide groove 63, so that the support seat can only rotate to one side, further adjusting the angle between the base 6 and the support seat.

[0036] like Figure 10 As shown, the base 6 includes a base 61 and a splint 62. The splint 62 is formed on the upper surface of the base 61. A pin hole 64 is also provided on the splint 62. The support seat is located in the splint 62. The splint 62 limits the two sides of the support seat, and the pin allows the support seat to swing between the splints 62.

[0037] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
