Description

Technical Field

[0001] The utility model relates to the technical field of daily necessities, in particular to a rotating opening and closing structure and a storage rack. Background Art

[0002] In daily life, towel racks or clothes drying racks are generally used to hang towels or clothes. In today's social life, people's living space is limited. Towel racks or clothes drying racks are often fixed to the wall and cannot be moved according to usage needs. When not in use, they take up a lot of space, causing waste of space and inconvenience for people's activities.

[0003] Early wall-mounted storage racks installed in bathroom spaces usually include two fixing bases that can be mounted on the wall, and a hanging rod connected between the fixing bases, and towels can be hung through the hanging rod.

[0004] The above-mentioned hanging rod is fixed in design and cannot be moved or rotated. In addition, it is parallel to the wall, and the space between it and the wall is narrow, making it difficult to add a hanging rod, resulting in a limited amount of towel hanging. Usually, the amount of towel hanging can only be increased by lengthening the hanging rod, but the long hanging rod cannot be applied to narrow walls and has poor aesthetics.

[0005] Domestic announcement number CN2200398Y "Mobile towel hanger" utility model patent discloses a towel hanger that can be installed on the wall, which is provided with two hanging rods, which can be rotated horizontally to adjust the angle position of the hanging rods after the screws are loosened, and the hanging rods are locked by tightening the screws. Although the hanging rods of the patent case can be rotated to a suitable angle to facilitate users to hang towels and increase the amount of towels hung in a smaller space, each rotation adjustment of the hanging rod must be achieved through the tightening and loosening of the screws, so the operation is not very convenient, and the hanging rod can only be adjusted within a range of 90 degrees, and the space state of use will still be limited.

[0006] A Chinese patent with authorization announcement number CN202173348U discloses a wall-mounted rotating towel rack, comprising a base that can be installed on a wall and at least a cantilever with a longitudinal rod portion; two hanging rods respectively having a hanging rod portion and a sleeve portion; two elastic bushings that can be respectively embedded in each sleeve portion, on which an elastic deformation portion with a convex rib structure on the outer wall is formed, which can produce elastic contraction deformation when the convex rib structure is squeezed inward by each sleeve portion; two shaft rods, which can limit the axial penetration of each elastic bushing together with the hanging rod thereon at the upper and lower ends of the longitudinal rod portion of the base, and can be tightened by the elastic deformation portion, so that the hanging rod can be rotated and adjusted relative to the elastic bushing under appropriate damping; two annular washers respectively installed near the outer end of the shaft rod can respectively radially and axially resist the elastic bushing, thereby preventing the hanging rod from swinging up and down and axially shaking. The above towel rack has too few hanging rods, a complex structure, many parts, and a high support cost, which makes it inconvenient to repair in the future. In addition, the wall-fixed structure makes the towel rack unable to be moved, which limits its use.

[0007] In view of this, the present invention aims at solving the problems of fewer hanging rods, single function, complex structure, inconvenient maintenance, etc. in existing storage racks such as towel racks or clothes drying racks, and actively studies, improves and tests to develop the present invention.

[0057] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.

[0058] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0059] like Figures 1 to 16 As shown, the utility model discloses a rotating opening and closing structure 10, which includes a support 1 and a plurality of fan blades 2, the support 1 having an upper mounting seat 11 and a lower mounting seat 12, the plurality of fan blades 2 are respectively installed at the front end of the support 1 through detachable intervals of a rotating shaft 3, the rotating shaft 3 is rotatably installed on the support 1, the top end of the rotating shaft 3 is connected to the upper mounting seat 11, the bottom end of the rotating shaft 3 is connected to the lower mounting seat 12, one end of the plurality of fan blades 2 is connected to the rotating shaft 3 and is located between the upper mounting seat 11 and the lower mounting seat 12.

[0060] The plurality of blades 2 of the rotary opening and closing structure of the utility model are rotatably mounted on the support 1 through the rotating shaft 3. When the blades 2 are needed, the blades 2 can be unfolded relative to the support 1 to increase the distance between the blades 2, which is convenient for drying or hanging towels or clothes. The blades 2 can be disassembled from the support 1 for easy cleaning, maintenance or use. The top surface and bottom surface of one end of the blade 2 connected to the rotating shaft 3 are respectively limited by the upper mounting seat 11 and the lower mounting seat 12, which enhances the stability of the blades 2 after installation, and can limit the blades 2 to prevent the blades 2 from easily detaching from the support 1.

[0061] like Figure 1 and Figure 2As shown, it is the first embodiment of the rotary opening and closing structure 10 of the utility model. In this embodiment, a plurality of first axial holes 13 are arranged at equal intervals on the support 1, and a plurality of openings 14 are arranged at the front ends of the upper mounting seat 11 and the lower mounting seat 12 of the support 1 to communicate with the first axial holes 13, and the width of the opening 14 is smaller than the inner diameter of the first axial hole 13. A first connector 21 with the rotating shaft 3 is fixedly arranged at one end of the fan blade 2, one end of the first connector 21 fixes the fan blade 2, and the other end fixes the rotating shaft 3, the height of the first connector 21 is less than or equal to the spacing between the upper mounting seat 11 and the lower mounting seat 12, the width of the first connector 21 is slightly larger than the width of the opening 14, the outer diameter of the rotating shaft 3 corresponds to the inner diameter of the first axial hole 13, and the two ends of the rotating shaft 3 protrude from the top and bottom of the first connector 21. During installation, align the rotating shaft 3 on the fan blade 2 with the opening 14 on the support 1. Since the opening 14 and the opening 14 have a certain elasticity, the opening 14 will be stretched open when the rotating shaft 3 is inserted into the opening 14, so that the rotating shaft 3 can be inserted into the first shaft hole 13, and the fan blade 2 can be rotatably installed on the support 1. The first connecting head 21 of the fan blade 2 is stuck under the opening 14 between the upper mounting seat 11 and the lower mounting seat 12. Since the width of the first connecting head 21 is greater than the width of the opening 14, after the installation is completed, the first connecting head 21 can be limited by the upper mounting seat 11 and the lower mounting seat 12 on both sides of the opening 14 to prevent the fan blade 2 from detaching from the support after installation.

[0062] In order to further prevent the rotating shaft 3 from sliding downward under the action of gravity after installation, the rotating shaft 3 and the support 1 are further provided with a limiting mechanism, for example, the bottom end of the first shaft hole 13 can be directly set on the lower mounting seat 12, and after the rotating shaft 3 is installed, its bottom directly abuts against the lower mounting seat 12. In this embodiment, the rotating shaft 3 is provided with a limiting block 31 protruding from the rotating shaft 3, and one side of the first shaft hole 13 of the support 1 is provided with a groove 15 for the limiting block 31 to move. The limiting block 31 on the rotating shaft 3 is installed in the groove 15 of the support 1, which can not only prevent the rotating shaft 3 from sliding downward, but also limit the rotation angle of the rotating shaft 3 through the size of the groove 15.

[0063] In this embodiment, the support 1 is a rectangular structure with chamfered corners on all sides. The front ends of the upper mounting seat 11 and the lower mounting seat 12 are respectively provided with a first axial hole 13, and the rear ends of the upper mounting seat 11 and the lower mounting seat 12 have a connecting seat, which is integrally formed with the upper mounting seat 11 and the lower mounting seat 12.

[0064] In this embodiment, the fan blade 2 is a hollow rectangular structure with an opening at the bottom, and a plurality of cross bars can be arranged at intervals at the bottom opening of the fan blade 2, and the cross bars can be used to install hooks.
