Description

Technical Field

[0001] This utility model relates to the field of hardware products technology, specifically a suction cup. Background Technology

[0002] Based on the patented product launched by our company, and the prior art of its publication number CN221810959U, since the shell and the suction cup soft body are connected, the position between the shell and the suction cup soft body is relatively stationary. It relies entirely on the sliding part to slide and drive the suction cup soft body to deform, that is, to use the sliding part to make the suction cup soft body adhere to the contact surface or separate from the contact surface. Although this method can also complete the suction cup adsorption and separation actions, the sliding part is small, and a lot of force is required when holding it during the snapping process, which can easily cause discomfort to the user. In addition, during the snapping process, the entire suction cup may fall off the hand with the slightest carelessness, which can easily lead to the suction cup being broken. Utility Model Content

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.

[0021] Please see Figure 1-6 The present invention provides an embodiment of a suction cup, comprising a suction cup body 1 and a housing 2 covering the outside of the suction cup body 1; the suction cup body 1 is further provided with a connecting part 10, and the connecting part 10 is further provided with a sliding block 11; the housing 2 is further provided with a driving part 23, by which the housing 2 slides outside the suction cup body 1, so that the sliding block 11 slides on the driving part 23, thereby causing the suction cup body 1 to adhere to the contact surface or separate from the contact surface.

[0022] In summary, because the housing 2 can slide relative to the suction cup 1 during use, the suction cup can be made to adhere to or separate from the contact surface during the sliding process, thus solving the problem of discomfort caused by pushing with a finger. At the same time, by holding the housing 2 and moving it, the entire suction cup can be controlled by the user, whether it is adhering to or separating from the contact surface, completely eliminating the problem of the suction cup being broken due to falling.

[0023] Furthermore, since the driving part 23 is also provided with a first stop part 21 and a second stop part 22, wherein the second stop part 22 is higher than the first stop part 21, when the sliding block 11 slides from the first stop part 21 to the second stop part 22, since the second stop part 22 is higher than the first stop part 21, when the sliding block 11 slides to the second stop part 22, it can stretch the suction cup soft body 1 to promote the suction cup soft body 1 to adhere to the contact surface; conversely, it drives the release of the suction cup soft body 1 so that the suction cup soft body 1 can separate from the contact surface.

[0024] In addition, since the first stop 21 smoothly transitions to the second stop 22 through the inclined surface 24, the sliding block 11 can slide smoothly between the two stops. At the same time, when the sliding block 11 contacts the first stop 21, it can prevent the suction cup soft body 1 from separating from the housing 2. When the sliding block 11 contacts the second stop 22, it can lock the relative position between the housing 2 and the suction cup soft body 1.

[0025] Based on the above solution, since the suction cup soft body 1 is adsorbed to the contact surface, the side of the shell 2 facing the contact surface is attached to the contact surface. Therefore, the shell 2 can be used to cover the outside of the suction cup soft body 1, which can reduce the amount of dust entering the suction cup soft body 1.

[0026] Based on the above solution, a pressure cap 3 is also included, which is installed on the outer side of the housing 2. By pressing the pressure cap 3, the suction cup soft body 1 makes contact with the contact surface before the housing 2. Therefore, after the suction cup soft body 1 makes initial contact with the contact surface, pressing the pressure cap 3 presses the suction cup soft body 1 onto the contact surface, thereby achieving initial positioning of the suction cup and providing reliable support for the smooth sliding of the housing 2.

[0027] Specifically, the inner wall surface of the pressure cover 3 is provided with a protrusion 30. After the pressure cover 3 is pressed, the protrusion 30 abuts against the connecting part 10 to cause the suction cup soft body 1 to contact the contact surface. Therefore, the protrusion 30 can be used to enhance the pressure effect of the pressure cover 3 on the suction cup soft body 1.

[0028] Meanwhile, since the protrusion 30 is configured in an inverted T shape, the contact area between the protrusion 30 and the end face of the sliding block 11 can be increased, so that the protrusion 30 and the sliding block 11 have a longer contact stroke during the sliding process of the housing 2, thereby ensuring that the suction cup soft body 1 can reliably contact the contact surface during the sliding process of the housing 2.

[0029] To facilitate the installation of the pressure cap 3 and ensure reliable linkage between the pressure cap 3 and the housing 2, the pressure cap 3 is connected to the insertion hole 20 on the housing 2 via a pin 31. Furthermore, the pressure cap 3 and the housing 2 are separate structures, which facilitates the assembly of the suction cup soft body 1 and the housing 2, as well as the processing of the drive unit 23.

[0030] 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.
