[0002] The existing suction cups used in daily life are generally round and concave in the middle. They mainly include a fixed suction cup body, and then a hook is drawn out from the suction cup body, and some parts that cooperate with the hook (such as the handle on a plastic bag, the hook on a hanger, etc.) are hung through the hook. Then, the suction cup body is caused to be adsorbed on the support surface by rotating the knob or turning the paddle. For example, the prior art with the announcement number CN204784112U uses a knob to complete the adsorption of the suction cup software on the support surface; the prior art with the announcement number CN221469735U uses a paddle to cause the suction cup software to be adsorbed on the support surface. The problem with this method is that the knob and the paddle both protrude from the shell, making the knob and the paddle easily hooked by objects, causing the paddle or the knob to loosen, and then causing the entire suction cup to fall off from the contact surface.

[0017] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limitations on the present invention. In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation on the present invention.

[0018] See also Figure 1-5 , an embodiment provided by the present utility model: specifically as Figure 1 、 Figure 2 Figure 3 and Figure 4 As shown, a suction cup comprises a shell 1, a suction cup body 3 installed on one side of the shell 1, and a locking member 2 installed on the other side of the shell 1; the locking member 2 is inserted into a slot 11 provided on the shell 1 through a hook 25 provided; the shell 1 is also provided with a plug hole 13; wherein, the plug hole 13 is connected to the slot 11, and the suction cup body 3 is also provided with a pin 4 that enters the slot 11 through the plug hole 13; after one side of the suction cup body 3 contacts the contact surface, the hook 25 is inserted into the slot 11 and connected to the pin 4, and as the hook 25 continues to move, the hook 25 causes the suction cup body 3 to be adsorbed on the contact surface.

[0019] To sum up, the suction cup can be adsorbed on or separated from the contact surface by sliding the locking member 2 on the shell 1, so the suction cup is simple and convenient to use. After the locking member 2 completes the locking action, it can be attached to the shell 1, which makes the position of the locking member 2 stable and reliable; secondly, the outer wall surface of the locking member 2 does not protrude from the shell 1, so it can effectively prevent the locking member 2 from being touched and causing the suction cup to fall off from the contact surface.

[0020] Furthermore, the hook body 25 has a flat surface 22 on the side that contacts the inner wall of the slot 11, and a sloped surface 23 is provided below the flat surface 22. Since the sloped surface 23 and the flat surface 22 are provided on the hook body 25, the connection between the sloped surface 23 and the flat surface 22 can serve as a fulcrum for the hook body 25. By pressing the hook body 25, one end of the hook body 25 can pry the latch 4, causing the suction cup body 3 to deform.

[0021] In addition to the above solution, the hook body 25 is further provided with a cylindrical pin 21, which is adapted to connect with the pin hole 10 provided on the housing 1. Therefore, when the cylindrical pin 21 is inserted into the pin hole 10, the stability of the connection between the locking member 2 and the housing 1 can be effectively improved. In particular, when the hook body 25 is pried, the pin hole 10 can guide the movement of the cylindrical pin 21, thereby ensuring that the locking member 2 reliably causes the suction cup body 3 to deform.

[0022] Furthermore, since one end of the hook body 25 is also provided with a driving portion 20, the driving portion 20 can be used to prompt the hook body 25 to be inserted into the slot 11, and the driving portion 20 can also expand the contact area with the user's hand, so as to quickly prompt the hook body 25 to hook the pin 4. In addition, since the other end of the hook body 25 is also provided with a protrusion 24, the protrusion 24 can be used to press against the outer wall surface inside the slot hole 11, and the flat surface 22 can press against the inner wall surface inside the slot hole 11, so that the position of the locking member 2 after installation is more stable and reliable.

[0023] In particular, the arrangement of the driving portion 20 further facilitates the user to press the driving portion 20 to tilt the hook 25 upward, thereby causing the suction cup body 3 to deform.

[0024] Furthermore, since the driving portion 20 is provided with a groove 26 on a side away from the housing 1 , it is convenient for the user's thumb to contact the groove 26 , so that the user's thumb can detent the locking member 2 .

[0025] Based on the above scheme, if Figure 5 As shown, since the housing 1 is connected to the support frame 5, and the support frame 5 is adapted to be connected to the connection groove 12 provided on the housing 1 via the connection plate 6, it is possible to conveniently place items such as crossbars on the support frame 5. Specifically, two housings 1 are connected to a wall, and then crossbars or other shelves for hanging or placing items are connected to the support frame 5 to form a storage rack. Since the housing 1 can reliably contact the wall and will not easily fall off during the contact process, the storage rack can reliably carry items.

[0026] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
