Abstract

Regarding the structure for storage shelves, a connecting structure for storage shelves is provided. [Solution] This is a structure for joining a first storage shelf S1 and a second storage shelf S2. A positioning screw hole 30 is provided at the lateral end of the horizontal tube 20 of the first storage shelf, and the second storage shelf is provided with a horizontal fitting groove 40 and a support column through hole 50 at the corresponding height. When joining them, the first threaded portion 61 of a single bidirectional screw 60 with a reverse thread is screwed into the first storage shelf, and the second threaded portion 62 is inserted through the support column and into a limiting frame 70 fitted into the horizontal fitting groove. A rotation control wheel 80 is provided inside the limiting frame. The central screw hole 81 is screwed into the bidirectional screw. As a result, the user can quickly join, position, and fasten the two storage shelves by simply toggling the circumferential surface of the rotation control wheel exposed from the opening of the frame, thereby driving the bidirectional screw and generating displacement.

[Modes for carrying out the invention]

[0010] The embodiments of this invention will be described below with reference to the drawings.

[0011] Figures 1 to 6 show preferred embodiments of the storage shelf coupling structure according to the present invention, but these embodiments are merely illustrative, and of course, the utility model registration application is not limited to these structures.

[0012] The storage shelf coupling structure according to the present invention is for positioning and coupling adjacent first storage shelf S1 and second storage shelf S2. The first storage shelf S1 and the second storage shelf S2 each comprise a plurality of support columns 10 and a plurality of horizontal tubes 20 that are at the same height, lined up in a row, and facing each other. The storage shelf coupling structure according to the present invention comprises a positioning screw hole 30 formed at the lateral end of the horizontal tube 20 of the first storage shelf S1, a horizontal fitting groove 40 formed in the horizontal tube 20 of the second storage shelf S2 adjacent to the first storage shelf S1, a tube through hole 50 formed in the support column 10 of the second storage shelf S2, which is at the same height and in a matching relationship with the horizontal fitting groove 40, and a first threaded portion 61 and a second threaded portion 62 whose helical directions are opposite to each other, the first threaded portion 61 being a bidirectional screw 60 that screws into the positioning screw hole 30, and may be made of resin material, which is fitted into the horizontal fitting groove 40 and positioned, and has a storage space 71, and storage space At least one opening 72 is formed in the space 71, and perforations 73 are formed on both sides of the storage space 71, with each perforation 73 corresponding to the support column 10, and a limiting frame 70 into which the second threaded portion 62 of a bidirectional screw 60 can be inserted into the storage space 71, and a rotation control wheel 80 which can be rotated by the user by applying force within the storage space 71 of the limiting frame 70, and which has a central screw hole 81 and a circumferential surface 82, the central screw hole 81 corresponding to the perforation 73 of the limiting frame 70 so that the second threaded portion 62 of the bidirectional screw 60 is screwed into the central screw hole 81, and the circumferential surface 82 is exposed corresponding to the opening 72. The rotation control wheel 80 may or may not protrude from the opening 72. As shown in Figure 10, the user can achieve the purpose of connecting the storage shelves by using the clockwise and counterclockwise rotation of the rotation control wheel 80 to tighten or loosen the bidirectional rotation of the bidirectional screw 60.

[0013] Refer to Figures 6 and 10. In this embodiment, the restricting frame 70 has a second opening 74 formed on the opposite side of the opening 72. That is, the restricting frame 70 may have only one opening or it may have bidirectional openings.

[0014] Refer to FIGS. 4 to 6. In the present embodiment, on the peripheral surfaces of the opening 72 and the second opening 74, a convex frame edge 75 for being positioned by fitting into the horizontal fitting groove 40 is further formed. In the present embodiment, it mainly shows that the restriction frame 70 is positioned in the horizontal fitting groove 40.

[0015] Also, on the peripheral surface 82 of the rotation control ring 80, as shown in FIG. 10, an anti-slip portion 83 is further formed (for example, partially or entirely). The shape of the anti-slip portion 83 (for example, the shape of the wrinkles of the anti-slip portion 83) is any of a tooth shape, a cross shape, a dot-like protrusion, a wave shape, or the cross-sectional shape of the peripheral surface 82 is set to any of the contour shapes of a plurality of protrusions (for example, a large number of neatly arranged protrusions), a plum blossom shape, and a polygon arranged at intervals in the circumferential direction. Thereby, the peripheral surface 82 of the rotation control ring 80 provides excellent frictional force during operation. As a result, the user can easily operate the rotation control ring 80, and there are advantages such as a pleasant rotation operation and easy handling.

[0016] Refer to FIG. 12. In the present embodiment, a retaining edge portion 76 is further formed in the accommodation space 71 of the restriction frame 70. Thereby, it is possible to prevent the rotation control ring 80 from being stopped and easily escaping from the accommodation space 71. Regarding the present embodiment, it should be particularly noted that after the rotation control ring 80 is placed in the accommodation space 71 of the restriction frame 70 and the central screw hole 81 is screwed with the second thread portion 62 of the bidirectional screw 60, the rotation control ring 80 has no possibility of escaping from the accommodation space 71. Therefore, here, it refers to the case where the second thread portion 62 of the bidirectional screw 60 is not screwed with the central screw hole 81. That is, in the state where the rotation control ring 80 is only placed in the accommodation space 71, the rotation control ring 80 can roll, so there is a possibility of escaping from the accommodation space 71.

[0017] As described above, when performing the joining operation using the storage shelf joining structure according to the present invention, first, as shown in Figure 6, the user screws the second threaded portion 62 of the bidirectional screw 60 into the central screw hole 81 provided in the rotation control wheel 80 of the second storage shelf S2, causing the first threaded portion 61 to protrude from one side of the support column 10 of the second storage shelf S2. Next, as shown by arrow L1, the user brings the lateral tube 20 of the first storage shelf S1 to be joined closer together. The first threaded portion 61 is screwed into the positioning screw hole 30 provided in the lateral tube 20 of the first storage shelf S1. At this time, as shown in Figures 7 and 8, the user rotates the rotation control wheel 80 as shown by arrow L2, which rotates the bidirectional screw 60, tightening and joining the first storage shelf S1 and the second storage shelf S2 together. When the first storage shelf S1 is not connected to the second storage shelf S2, it is locked and secured by a bolt 63 instead of a bidirectional screw 60, as shown in Figure 9.

[0018] Refer to Figure 11. With the storage shelf coupling structure according to the present invention, the first storage shelf S1 and the second storage shelf S2, which are positioned and coupled together, can be tightened and coupled even if they are of different heights.

[0019] Furthermore, in some applications, the combined storage shelf structure according to the present invention may be such that the first storage shelf S1 of the extended combination is simply a towel rack derived from one or two horizontal tubes 20. Obviously, this form should also be a variation that can be easily understood from the present invention, so it will not be described in any further detail. [Explanation of Symbols]
