Description

Vacuum suction seat

The present invention relates to a "vacuum holder in an evacuated state", and more particularly to an adsorption seat structure which can be vacuumed after adsorption.

According to the adsorption seat, the adsorption seat has the function of being adsorbed on the flat surface and fixed, and the adsorption process is convenient and fast, and does not need to perform the action of drilling or nailing into the nail, so that it is deeply loved by consumers for daily life. Widely used in the bathroom, kitchen, car, glass or wall, can be found with the adsorption seat to fix the structure, and the conventional adsorption seat (90), as shown in the eighth figure, it contains: a suction cup (91), a fixing member (92), a spring (93) and a control handle (94), wherein a suction rod (911) protrudes from a center surface of one side of the suction cup (91), and the fixing member (92) is A cover body is provided with a through hole (921) at the center, and the outer side is provided for various kinds of objects or positioning structures, and the control handle (94) has an eccentric portion (941) at the pivot joint, and the spring (93) is sleeved when combined. On the pull rod (911) of the suction cup (91), the suction cup (91) is pierced by the through hole (921) of the fixing member (92) with the pull rod (911), so that the suction cup (91) can be fixed (92). The cover handle (94) is further pivoted to the pull rod (911) of the suction cup (91) through the fixing member (92), whereby when the suction cup (91) is attached to the flat surface The control handle (94) can be pulled, the control handle (94) can be pressed against the fixing member (92) with the eccentric portion (941), and the suction cup (91) can be pulled up to allow the suction cup (91) to pass through the The deformation of the pull-up produces suction to smoothly adsorb on the flat surface.

However, the conventional structure as described above still has the following problems in practical applications: when the suction cup (91) is attached to the flat surface, it still leaves between the suction cup (91) and the flat surface. a small amount of air, and the suction cup (91) is simply pulled up, and the air is not completely extracted or discharged, and the air still remains between the suction cup (91) and the flat surface after the suction cup (91) is adsorbed. The problem is that it is impossible to achieve a fully vacuum adsorption seat structure, and there will be a phenomenon that insufficient suction force may cause the adsorption seat (90) to suck up and then fall easily.

Therefore, the present inventors have invented the present invention in view of the fact that the idea of creation and creation has been designed with many years of experience, and has been explored and tested by various parties, and has been repeatedly modified and improved.

Conventional suction cups are simply pulled up, and the air is not completely extracted or discharged, and air remains between the suction cup and the flat surface. This is a technical problem to be solved.
