[0026] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0028] The present invention provides a rotating mechanism, please refer to Figures 1 to 5 , including: a first operating part 1; a second operating part 2; a rotating component 3, the rotating component 3 is arranged between the first operating part 1 and the second operating part 2, and the rotating component 3 is respectively connected to the first operating part 1 and the second operating part 2 so that the first operating part 1 rotates relative to the second operating part 2; the rotating component 3 is movably arranged in a direction close to or away from the first operating part 1, and a contact end surface abutting against the first operating part 1 is provided on the rotating component 3, so that the first operating part 1 is located in a predetermined position when the first operating part 1 and the abutting end surface abut against each other.

[0029] The present invention provides a rotating mechanism comprising a first operating portion 1, a second operating portion 2, and a rotating member 3. The rotating member 3 is disposed between the first operating portion 1 and the second operating portion 2 and is connected to the first operating portion 1 and the second operating portion 2, respectively, so as to rotate the first operating portion 1 relative to the second operating portion 2. The rotating member 3 is movable toward or away from the first operating portion 1. The rotating member 3 is provided with an abutting end surface that abuts the first operating portion 1, so that when the first operating portion 1 and the abutting end surface abut each other, the first operating portion 1 is positioned in a predetermined position. This arrangement has a simple structure. The abutting end surface abuts the first operating portion 1 to abut against each other, so that the first operating portion 1 is positioned in a predetermined position. During the rotation of the first operating portion 1, an operator only needs to overcome the abutting force. When the first operating portion 1 is rotated to the desired position, the operator does not apply any force to the first operating portion 1. The first operating portion 1 is fixed by the abutting force with the abutting end surface. The operation is simple and convenient. When the rotating mechanism is applied to a shelf, the shelf can be folded, thereby improving the shelf's utilization efficiency.

[0030] In a specific implementation, the first operating part 1 has a first position and a second position, the abutting end face has a first abutting end face and a second abutting end face, the first abutting end face and the second abutting end face are spaced apart along the circumferential direction of the rotating part 3, and the first abutting end face and the second abutting end face are staggered in the radial direction of the rotating part 3, that is, the first abutting end face and the second abutting end face are not on the same circumferential surface. When the first operating part 1 abuts against the first abutting end face, the first operating part 1 is in the first position; when the first operating part 1 abuts against the second abutting end face, the first operating part 1 is in the second position.

[0031] Specifically, to ensure that the abutting end surface and the first operating portion 1 always maintain abutting force, the rotating mechanism further includes an elastic member 4, the first end of which is connected to the rotating member 3, and the second end of which is connected to the second operating portion 2, so that the elastic force of the elastic member 4 is used to push the rotating member 3 toward the first operating portion 1. In this way, when rotating the first operating portion 1, only the elastic force of the elastic member 4 needs to be overcome, making the operation convenient.

[0032] In order to avoid the rotating part 3 and make the first operating part 1 cooperate with multiple abutting end faces respectively, an avoidance space 10 is provided on the first operating part 1, and at least part of the rotating part 3 extends into the avoidance space 10; the rotating mechanism also includes: a sliding block 5, which is provided on the first operating part 1, and at least part of the sliding block 5 abuts against the abutting end faces.

[0033] In the embodiment provided by the present invention, a guide portion 30 is provided on the circumferential surface of the rotating component 3, and the abutting end surface is provided on the guide portion 30. In this arrangement, during the rotation of the first operating component 1, the first operating component 1 is guided by the cooperation between the sliding block 5 and the guide portion 30. The guide portion 30 is provided on the circumferential surface of the rotating component 3, so that the rotating component 3 can cooperate with the sliding block 5 and be limited within the avoidance space 10 of the first operating component 1, thereby saving installation space.

[0034] In the specific implementation process, the guide portion 30 includes: a first step structure 31, the first step end surface of the first step structure 31 is a first abutting end surface; a limiting structure 32, which is spaced apart from the first step structure 31 along the circumferential direction of the rotating component 3, and the limiting structure 32 has a second abutting end surface, and the sliding block 5 is movably arranged between the first abutting end surface and the second abutting end surface; along the radial direction of the rotating component 3, the first abutting end surface and the second abutting end surface are staggered. It should be noted here that the staggered arrangement of the first abutting end surface and the second abutting end surface means that the first abutting end surface and the second abutting end surface are not on the same circumferential surface, so that the first operating portion 1 has a first position abutting against the first abutting end surface and a second position abutting against the second abutting end surface.

[0035] In order to make the sliding block 5 slide smoothly to the second abutting end surface, the limiting structure 32 includes: a blocking block 320, which has a guide end surface 321, which is inclined relative to the first step end surface; a second step structure 322, which has a second step end surface, which is the second abutting end surface, and at least a part of the second step structure 322 is opposite to the blocking block 320. After the sliding block 5 passes the guide end surface 321, it slides to the second step end surface. Figure 4 As shown, when the sliding block 5 rotates from the first abutting end surface to the guide end surface 321, it first contacts the guide end surface 321, and under the elastic force of the elastic component 4, pushes the rotating component 3 to move toward the direction close to the first operating part 1, thereby causing the sliding block 5 to slide to the second abutting end surface. At this time, the first operating part 1 is in the second position.

[0036] In the embodiment provided by the present invention, the rotating component 3 further includes a rotating channel 33, which is arranged in sequence with the guide portion 30 along the axis of the rotating component 3. The two ends of the rotating channel 33 are respectively connected to the guide portion 30 to form a sliding channel for the sliding block 5. The sliding block 5 abuts the first abutting end surface after passing through the rotating channel 33 from the second abutting end surface. The rotating channel 33 is provided with a first sliding surface, and the guide portion 30 is provided with a second sliding surface. The first step structure 31 is located between the first and second sliding surfaces. This arrangement enables the reciprocating rotation of the first operating portion 1, and the rotating channel 33 enables the first operating portion 1 to move from the second position to the first position. Specifically, the rotary channel 33 has a transition channel and an arc channel that are interconnected. The transition channel is located on the side of the second step structure 322. When the first operating part 1 is in the second position, the first operating part 1 continues to be rotated, and the sliding block 5 is disengaged from the second abutting end face. The rotating part 3 continues to move toward the direction close to the first operating part 1 under the action of the elastic part 4, so that the sliding block 5 slides from the transition channel into the arc channel. The first operating part 1 is continued to be rotated to make the sliding block 5 slide to the first position, that is, the sliding block 5 is in contact with the first abutting end face.

[0037] In a specific implementation, the rotary channel 33 has a first side surface angled relative to the first sliding surface, the guide portion 30 has a second side surface angled relative to the second sliding surface, and a third step structure 6 is provided between the first and second side surfaces. The third step structure 6 has a third step end surface, which is coplanar with the first step end surface. This allows the first and third step end surfaces to cooperate with the sliding block 5, thereby improving the stability of the sliding block 5.

[0038] Specifically, the second operating portion 2 is provided with a mounting groove 20, in which at least a portion of the rotating component 3 is mounted. The second operating portion 2 further includes a limiting post 21, at least a portion of which is inserted into the rotating component 3 to connect the rotating component 3 to the second operating portion 2. A limiting groove 34 is provided on the rotating component 3, in which at least a portion of the limiting post 21 is inserted. There are multiple limiting posts 21 and multiple limiting grooves 34, and the multiple limiting grooves 34 are spaced apart along the circumferential direction of the rotating component 3. The multiple limiting grooves 34 are provided in a one-to-one correspondence with the multiple limiting posts 21. The rotating component 3 is annular, and the limiting grooves 34 are provided on the inner circumferential surface.

[0039] Specifically, the rotating component 3 has a connecting end surface connected to the elastic component 4 , and a fourth step structure is provided between the connecting end surface and the circumferential end surface of the rotating component 3 to limit the elastic component 4 .

[0040] like Figure 6 and Figure 7As shown, the present invention also provides a storage rack, comprising: a main frame 100; a movable frame 200; and a rotating mechanism 300 of the above embodiment, wherein the first operating portion 1 of the rotating mechanism 300 is connected to the movable frame 200, and the second operating portion 2 of the rotating mechanism 300 is connected to the main frame 100, so that the movable frame 200 is rotatably arranged relative to the main frame 100.

[0041] The rotating mechanism provided by the present invention is installed on the storage rack. The first operating part 1 of the rotating mechanism 300 is connected to the movable frame 200 of the storage rack, and the second operating part 2 is connected to the longitudinal beam of the main frame 100. This can realize a 90-degree rotation of the movable frame 200, transforming the horizontal structure of the storage rack into a basket-type structure, which can accommodate more objects and improve the utilization rate of the storage rack.

[0042] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0043] The present invention provides a rotating mechanism comprising a first operating portion 1, a second operating portion 2, and a rotating member 3. The rotating member 3 is disposed between the first operating portion 1 and the second operating portion 2 and is connected to the first operating portion 1 and the second operating portion 2, respectively, so as to rotate the first operating portion 1 relative to the second operating portion 2. The rotating member 3 is movable toward or away from the first operating portion 1. The rotating member 3 is provided with an abutting end surface that abuts the first operating portion 1, so that when the first operating portion 1 and the abutting end surface abut each other, the first operating portion 1 is positioned in a predetermined position. This arrangement has a simple structure. The abutting end surface abuts the first operating portion 1 to abut against each other, so that the first operating portion 1 is positioned in a predetermined position. During the rotation of the first operating portion 1, an operator only needs to overcome the abutting force. When the first operating portion 1 is rotated to the desired position, the operator does not apply any force to the first operating portion 1. The first operating portion 1 is fixed by the abutting force with the abutting end surface. The operation is simple and convenient. When the rotating mechanism is applied to a shelf, the shelf can be folded, thereby improving the shelf's utilization efficiency.
