Description

Suction device

technical field

The utility model relates to a sucker device, in particular to an innovative structure capable of controlling the elastic state during adsorption.

Background technique

If general objects are to be fixed on the surface of vertical objects (such as walls, wooden wallboards), gecko nails or adhesive stickers can usually be used to assist it, but the disadvantage is that it is not easy to change the position, and it is easy to cause holes in the wall after use Or sticky stickers that have not been cleaned, which is very unsightly. Therefore, for some items with smooth surfaces, such as tiles or glass surfaces, suction cups are usually used to hold them on the surface, so that items such as soap boxes, storage racks, etc. can be fixed on the smooth surface by the suction cups. However, the fixing power of simply using the suction cup to absorb is inevitably insufficient, and the long-term use of the suction cup is prone to elastic fatigue and loss of suction, resulting in frequent shedding.

At present, the mounts of electronic products connected inside and outside the car (such as mobile phones or personal digital assistants) are usually clamped by clips to the outlet of the air conditioner or the position of the car cigarette lighter, but the actual use may vary depending on the model. Not every car has an ideal position when using the fixed seat, so that the user can clearly see the screen information of the electronic product. Therefore, if the glass on the car can be utilized and a connecting rod structure with a suction cup can be used, another option for the user can be provided to adjust it to a position most suitable for the user to watch.
