Other technical contents, features and effects of the present invention will be clarified in the detailed description of the preferred embodiments below with reference to the drawings.

The potter's wheel structure according to the present invention can be applied to an upper potter's wheel, a middle potter's wheel, or a lower potter's wheel, and since they differ only in position, the potter's wheel structure according to the present invention can of course be applied to an upper potter's wheel, a middle potter's wheel, or a lower potter's wheel. It is not limited to.

Please refer to FIGS. 1 and 2.
FIG. 1 is an exploded perspective view showing the overall structure of a potter's wheel structure according to an embodiment of the present invention. FIG. 2 is an exploded side view showing the overall structure of a potter's wheel structure according to an embodiment of the present invention. As shown in FIGS. 1 and 2, a potter's wheel structure according to an embodiment of the present invention is composed of at least a potter's wheel main body 1 and a protective cover 2.

The potter's wheel main body 1 is formed into an annular shape, and a center rod 3 is fitted in the annular center in the axial direction. The potter's wheel main body 1 has a convex ring 11, a plurality of vertical grooves 12, a circumferential groove 13, and an engagement seat 14.
The convex ring 11 protrudes from the outer periphery of the potter's wheel body 1. Each vertical groove 12 is formed on the convex ring 11, is parallel to the axial direction of the potter's wheel body 1, and is evenly arranged in the circumferential direction of the potter's wheel body 1. A circumferential groove 13 is also formed on the convex ring 11. The circumferential groove 13 has the same circumferential direction as the potter's wheel main body 1, and communicates with each vertical groove 12, respectively. The depth of each longitudinal groove 12 is deeper than the circumferential groove 13.

The engagement seat 14 is formed on the convex ring 11 and located between the two longitudinal grooves 12 . The engagement seat 14 has two engagement pieces (snaps) 141 , a housing space 142 , and a stopper groove 143 . The engagement piece 141 and the accommodation space 142 are located above the circumferential groove 13 , and the stopper groove 143 is located below the circumferential groove 13 . The two engaging pieces 141 are provided symmetrically with respect to each other.
The accommodation space 142 is located between the two engagement pieces 141 , the accommodation space 142 communicates with the circumferential groove 13 , and an engagement groove 144 is formed on the inner surfaces of the two engagement pieces 141 that face each other. Each is formed. The stopper groove 143 of this embodiment is formed on the convex ring 11 and is provided adjacent to the circumferential groove 13 . The convex ring 11 has a stopper portion 111. The stopper portion 111 is locked between the stopper groove 143 and the circumferential groove 13.

The protective cover 2 has two engaging blocks 21 and a position regulating block 22. The two engaging blocks 21 are provided on both sides of the protective cover 2, respectively. The thickness of the protective cover 2 is greater than the thickness of each engaging block 21, and the cross section of the two engaging blocks 21 of the protective cover 2 is formed into a trapezoidal shape. The position regulating block 22 is formed at one end of the protective cover 2 . The position regulating block 22 is formed perpendicularly to the protective cover 2. The position regulating block 22 and the protective cover 2 are formed in an L-shape.

Please refer to FIGS. 3 and 4.
FIG. 3 is a partial plan view showing an umbrella rib and a wire coupled to a potter's wheel structure according to an embodiment of the present invention. FIG. 4 is a partial perspective view showing an umbrella rib and a wire coupled to a potter's wheel structure according to an embodiment of the present invention.
As shown in FIGS. 3 and 4, in the potter's wheel structure according to an embodiment of the present invention, a middle rod 3 is fitted into a potter's wheel main body 1, and an umbrella rib 4 is installed in each vertical groove 12, respectively. The wire 5 is installed in the circumferential groove 13 . Specifically, a perforation is formed at the end of the umbrella rib 4. The end of the umbrella rib 4 is inserted into the longitudinal groove 12. Since the wire 5 is wound within the circumferential groove 13 and each longitudinal groove 12 is in communication with the circumferential groove 13, the wire 5 is inserted into each longitudinal groove 12 and the umbrella in each longitudinal groove 12 is inserted. It is inserted through the perforation at the end of the bone 4, and this configuration connects the ends of the umbrella bones in each longitudinal groove 12. Both ends of the wire 5 are twisted and accommodated in the accommodation space 142.
See FIG. 5. FIG. 5 is a side view of a folding umbrella in which the potter's wheel structure according to an embodiment of the present invention is applied. A plastic nail 41 is provided in the umbrella rib 4 of this embodiment. Plastic nails 41 fix the structure of the umbrella rib 4. The plastic nails 41 are less likely to rust than conventional stainless steel nails, and produce less metal friction noise when opening the umbrella.

Please refer to FIGS. 3 and 4.
As shown in FIGS. 3 and 4, the protective cover 2 is attached to the engagement seat 14 to cover the accommodation space 142. When actually assembling, the protective cover 2 is made to correspond to the accommodation space 142, the position regulating block 22 is made to correspond to the stopper groove 143, and the protection cover 2 is pushed into the accommodation space 142.
In the pushing process, when the two engaging pieces 141 are pushed outward and opened, the two engaging blocks 21 are pushed inside the two engaging pieces 141 and are respectively engaged in the two engaging grooves 144. Thereafter, the two engaging pieces 141 move inward due to the elastic recovery force of the material (for example, plastic material) and naturally return to their original positions, and accordingly, the position regulating block 22 is also inserted into the stopper groove 143. . Since the engagement block 21 and the position regulating block 22 restrain the position of the protective cover 2, the protective cover 2 is prevented from coming off. The engagement block 21 installed in the engagement groove 144 prevents the protective cover 2 from moving in the radial and circumferential directions of the potter's wheel body 1. The position regulating block 22 installed in the stopper groove 143 prevents the protective cover 2 from moving in the axial direction of the potter's wheel body 1.

In addition, in order to easily push the protective cover 2 between the two engaging pieces 141, a root portion 145 is provided at a position where the engaging piece 141 and the potter's wheel main body 1 come into contact with each other. In fact, the root portion 145 may be tapered. Since the wall thickness at the position where the root portion 145 and the potter's wheel body 1 abut each other is the thinnest, the displacement and swing width when the engagement piece 141 is pushed is large.

See FIG. 5.
FIG. 5 is a side view of a folding umbrella in which the potter's wheel structure according to an embodiment of the present invention is applied. As shown in FIG. 5, the potter's wheel structure according to one embodiment of the present invention is applied to the upper and lower wheels of an automatically opening/closing folding umbrella, but other embodiments can be applied to various types of umbrellas such as printed umbrellas, folding umbrellas, long umbrellas, etc. The present invention may be applied to other types of umbrellas, and is not limited to this embodiment.

Please refer to FIGS. 6 and 7.
As shown in FIGS. 6 and 7, a handle 6 is attached to the bottom end of the middle rod 3. The handle 6 of this embodiment is extendable and retractable, and the length is adjusted by extending and contracting the handle 6 by obtaining an extendable function due to the sleeve-type structure. When the handle 6 is long, it can be grasped, and when it is short, it can be stored.

As those skilled in the art will understand, although the preferred embodiments of the invention have been disclosed above, they are not intended to limit the invention in any way. Various changes and modifications can be made without departing from the spirit and scope of the present invention. Therefore, the scope of the utility model registration claims of the present invention should be broadly interpreted to include such changes and modifications.
