Abstract
Description
Technical Field
[0001] This utility model relates to the field of hand-pump suction cup technology, and in particular to a hand-pump suction cup bracket. Background Technology
[0002] Hand-pumped suction cups utilize atmospheric pressure to create negative pressure on the object being suctioned, achieving a vacuum suction effect. Specifically, when the hand-pumped suction cup is perpendicularly attached to the surface of the object, repeated pumping with the handle draws air out of the sealed cup, creating a vacuum suction effect. During this repeated suction process, the hand-pumped suction cup generates a certain negative pressure, increasing the pressure difference between the suction cup head and the object, thus generating suction and holding the object in place. It is widely used in industrial production, shipbuilding, automotive maintenance, and household cleaning. It is suitable for suction of various materials and surface shapes, such as glass, ceramic tiles, and marble.
[0003] In existing hand-pump suction cups, the hand pump and the bracket are usually separate structures. After the bracket is pressed onto the hand pump, it is fixed to the suction cup with screws. Then, the suction cup is attached to the suction surface by pressing the air hammer on the hand pump. This assembly method of separating the suction cup and the bracket will cause most of the hand pump to be exposed outside the bracket, which will greatly increase the probability of damage to the hand pump. This will cause the suction cup bracket to fall off and damage the items on the bracket. Therefore, this application provides a hand pump suction cup bracket to meet the needs. Utility Model Content
