TWM554137U - Suction pad - Google Patents

Abstract

A suction pad, include an elastic suction pad, a ventilate, a check valve, a controller, a force point, a stent. when the suction pad adsorption surface, suction cup air discharge, resulting in suction, when the pull control rod the air into the suction cup, suction pad off.

Description

Suction cup

The present invention relates to a suction cup device; in particular, a suction cup suction and discharge device which utilizes the control of the air in and out of the suction cup to generate the suction force of the suction cup.

The sucker device of the prior art mostly increases the suction force of the suction cup by outward traction, or absorbs by the negative pressure in the suction cup, and releases the suction force mode to pull the edge of the suction cup or pull in a strong reverse direction to make the air enter. And let the suction cup fall off.

This creation is based on the relationship between the elastic suction cup and the atmospheric pressure. It can be directly sucked and sucked by the manual suction cup, which includes a vent, an air cushion, a control rod, a bracket, and then the bracket adjusts the air in and out, causing the air pressure difference between the inside and the outside of the suction cup. To achieve the effect of sucking and sucking.

Figure 1 is an exploded view of the suction cup according to the present creation.

Figure 2 is a perspective view of the suction cup according to the creation.

In the first embodiment of the present invention, the suction device of the present invention comprises a suction cup 10, a venting opening 25, a stop air cushion 40, a control rod 50, a force applying point 55, and a bracket 52. When the suction cup 10 is to be sucked. When the surface is bonded, the bracket 52 or the force applying point 55 is biased toward the surface to be bonded, and the air in the suction cup 10 is discharged by the air vent 25, and when the force application point 55 is released, the air cushion 40 closes the air vent 25 to form a suction cup. 10 is closed, forming a closed space with the bonding surface to generate suction; when the user pulls the bracket 52 backward, the air stopping cushion 40 moves at the same time, and the outside air enters the suction cup 10 from the venting opening 25, and the suction force of the suction cup 10 disappears and falls off. Further, in the present embodiment, a spring 60 may be added to adjust the suction and discharge force of the suction cup 10.

This creation can provide users with the ability to easily change the suction cup position with one hand without the need for other equipment.
