[0002] Towel racks and similar storage racks consist of two supports holding one or more horizontal bars. They are typically mounted on bathroom walls for storing clothes, hanging towels, or bath towels. Currently, existing towel racks are generally divided into fixed and movable types.

[0003] Because the movable towel rack is designed to fold up, it can be folded upwards against the wall to save bathroom space. When fully folded downwards, the top surface of the towel rack is perpendicular to the wall. Therefore, the towel rack can only be used in two states: folded up and unfolded, which results in its relatively limited functionality. Utility Model Content

[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "upper surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this utility model.

[0028] Please see Figure 1-10 This utility model provides an embodiment of a shelf support, including a base 1, a connector 2 rotatably mounted on the base 1, and a ratchet 3, wherein the ratchet 3 is further provided with ratchet teeth 9; the connector 2 includes a rotating part 20, and the rotating part 20 is further provided with a first tooth groove 23 and a second tooth groove 24; the ratchet teeth 9 engage with the first tooth groove 23 to enable the connector 2 to complete a first locking state on the base 1; the outer wall surface of the ratchet teeth 9 abuts against the side of the first tooth groove 23 facing the second tooth groove 24 to enable the connector 2 to complete a second locking state on the base 1; the ratchet teeth 9 engage with the second tooth groove 24 to enable the connector 2 to complete a third locking state on the base 1; when the ratchet teeth 9 separate from the second tooth groove 24, the opposing surfaces of the connector 2 and the base 1 tend to be parallel, completing the storage state.

[0029] In summary, since the connector 2 can rotate on the base 1 to complete the first locking state, the second locking state, the third locking state, and the storage state, the towel rack with this support has multiple usage states, thus enriching the usage states of the towel rack.

[0030] Furthermore, since the unlocking element 4 is rotatably mounted inside the rotating part 20, the rotation of the connecting member 2 on the base 1 causes the unlocking element 4 to cause the ratchet 9 to separate from the outer wall surface of the rotating part 20. Therefore, the rotation of the connecting member 2 inside the base 1 can drive the unlocking element 4 to push the ratchet 9 of the ratchet 3 to separate from the rotating part 20, thereby disengaging the ratchet 3 from the locked state of the rotating part 20.

[0031] Furthermore, since the unlocking component 4 includes a pin portion 40, a protrusion 44 is provided on the radial surface of the pin portion 40, and a first contact surface 42 and a second contact surface 43 are formed between the protrusion 44 and the pin portion 40, and a third contact surface 41 is provided on the side of the pin portion 40 away from the protrusion 44, the unlocking component 4 can move in conjunction with or not move in conjunction with the connecting component 2 as needed, so that the unlocking component 4 can complete the unlocking task more easily.

[0032] Meanwhile, since the inner wall of the rotating part 20 is provided with a first pushing part 21, and the rotating part 20 is also provided with a second pushing part 25, the two pushing parts can cooperate to allow the unlocking member 4 to push the ratchet 3 to release the lock on the rotating part 20.

[0033] The specific working principle of this device is as follows; firstly, as Figure 2 As shown, rotate the connector 2 clockwise until the outer wall of the connector 2 is flush with the inner wall of the base 1. At this time, the ratchet 9 of the ratchet 3 is engaged in the first tooth groove 23, and the unlocking part 4 is in a free state, thus completing the construction of the first locking state.

[0034] Secondly, such as Figure 3 As shown, when the connector 2 is rotated counterclockwise, the ratchet 9 separates from the first tooth groove 23 until the outer side of the ratchet 9 passes over the first tooth groove 23. At this time, the support is in the second locking state. When clockwise rotation occurs, the inner side of the first tooth groove 23 abuts against the inner side of the ratchet 9, preventing the connector 2 from rotating clockwise. Therefore, the second locking state is established and the rotation is not counterclockwise, and the second locking state is maintained permanently.

[0035] Secondly, such as Figure 5As shown, in the second locking state, continue to rotate the connector 2 counterclockwise until the ratchet 9 of the ratchet 3 connects with the second tooth groove 24. At this time, the first pushing part 21 inside the connector 2 contacts the first contact surface 42, and the second contact surface 43 contacts the ratchet 3, thus completing the construction of the third locking state. The third locking state is kept constant by utilizing the mutual cooperation between the ratchet 9 and the second tooth groove 24.

[0036] When storage is required, continue rotating connector 2 counterclockwise from the third locking state. This counterclockwise rotation of connector 2 triggers the unlocking component 4, causing the protrusion 44 to push the ratchet 3 away from the second toothed groove 24, allowing connector 2 to enter the storage state. Figure 6 As shown.

[0037] When unfolded again, the connector 2 is rotated clockwise. After the second pushing part 25 inside the connector 2 contacts the third contact surface 41, the connector 2 is rotated clockwise again. At this time, the protrusion 44 on the unlocking part 4 pushes the ratchet 3 to completely disengage from the rotating part 20, so that the connector 2 can rotate clockwise smoothly. When the first tooth groove 23 engages with the ratchet tooth 9 of the ratchet 3 again, the first locking state is reconstructed.

[0038] Based on the above solution, since the base 1 is also equipped with a torsion spring 8, the torsion spring 8 causes one side of the ratchet 3 to always be in contact with the rotating part 20. Therefore, when the protrusion 44 is no longer in contact with the ratchet 3, the torsion spring 8 can cause the ratchet 3 to quickly contact the outer wall surface of the rotating part 20, or the first tooth groove 23 or the second tooth groove 24, and emit a "clicking" sound to remind the user that the device has changed from one state to another.

[0039] To facilitate the installation of towel bars or bath towel bars, a connecting part 22 is also provided on the circumferential surface of the rotating part 20. Furthermore, the connecting part 22 is also provided with a connecting hole 26. Based on this, after the towel rack or bath towel rack rod is connected to the connecting part 22, a fastener, such as a bolt, is used to pass through the rod and connect to the connecting hole 26, thereby improving the stability and reliability of the connection between the rod and the connecting part 22.

[0040] To facilitate the installation of the connector 2 and the ratchet 3 and to ensure that the ratchet 3 completes the locking task, the center of the rotating part 20 is rotatably connected to the base 1 through a first shaft pin 5, and the ratchet 3 is rotatably connected to the base 1 through a second shaft pin 6.

[0041] Furthermore, one end of the first shaft pin 5 and the second shaft pin 6 passes through the base 1 and is adapted to be connected to the provided pin 10.

[0042] Based on this, the two pins allow the ratchet 3 and the connector 2 to rotate reliably within the base 1. At the same time, by inserting the pin 10 into the corresponding hole on the pin, the pin and the base 1 can be fixed relative to each other. Conversely, the pin 10 can be removed to facilitate the removal of the connector 2 and the ratchet 3. The rotating part 20 consists of two parts, and the unlocking part 4 rotates between the two parts.

[0043] In addition, since the base 1 is provided with a mounting seat 7 on its inner bottom surface, bolts and other fasteners can be used to pass through the mounting seat 7 and connect to the wall to fix the support to the wall. At the same time, a pad can be installed between the base 1 and the wall.

[0044] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
