Abstract

This invention relates to a method for a suction pad which can be cnanged using different air pressure.

Description

 Suction cup  

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

The suction device of the prior art, for the adsorption and release mode, does not pay special attention to the suction of the suction cup except for the vacuum suction suction cup. If the suction cup position is desired to be changed at will, only the vacuum suction cup plus the equipment can be completed at present, in the known technology. There is no single device to complete.

Therefore, it is necessary to develop a simple method for the suction cup to be developed under the control of suction and release.

The invention relates to a device capable of directly sucking and dropping a manual suction cup with a relationship between an elastic suction cup and atmospheric pressure, which comprises a vent, an air cushion, a control rod, a vent hole added at the center of the elastic suction cup, and then a control rod and an air cushion. To adjust the air in and out, causing the air pressure difference between the inside and outside of the suction cup to achieve the suction and discharge effect of the suction cup.

In the first embodiment of the present invention, the suction cup device of the present invention comprises a suction cup 10, a venting opening 25, a stop air cushion 40, a control rod 50, and a force applying point 55, in order to make the embodiment easier to understand. In the embodiment of the invention, the vent 25 is subdivided into an air inlet 20 and an air outlet 30. When the suction cup 10 is to adsorb the bonding surface 90, the force applying point 55 is applied to the surface to be bonded 90, and the air in the suction cup 10 is discharged from the air discharge port 30. When the force application point 55 is released, the air stop 40 is closed. The air port 30 forms a suction cup 10 to close, and forms a closed space with the bonding surface to generate suction; when the user pulls the control rod 50 backward, the air stop 40 moves at the same time, and the outside air enters the suction cup 10 from the air inlet 20, the suction cup 10 The adsorption force disappears and falls off. Further, in the present embodiment, a spring 60 or a gear 65 may be added to adjust the suction and discharge force of the suction cup 10 by the strength of the spring 60 or the gear 65.

The second embodiment: the suction cup device of the present invention comprises a suction cup 10. In this example, an air inlet 20, a stop air cushion 40, a control rod 50, and a force application point 55 are all located on the same shaft. When the suction cup 10 is to be attracted to the bonding surface 90, the force applying point 55 is applied to the surface to be bonded 90, and the air cushion 40 is fixed to the control rod 50, and at the same time, the air vent 25 is sealed, and the air is sucked by the suction cup 10. And the sealing surface 90 is exhausted around, the suction cup 10 and the bonding surface 90 form a closed space to generate suction; when the user pulls the control rod 50 backward, the air stopping cushion 40 is simultaneously moved open, and the outside air enters the suction cup 10 from the air inlet 20 Inside, the lever 50 is pulled to pull the outward force of the suction cup 10, and the suction force of the suction cup 10 disappears and falls off.

In the above figures 1 and 2, the control rod 50 and the air cushion 40 can also be hidden in the force application point 55. As shown in FIG. 3, the control rod 50 and the air stop cushion 40 are separately driven by the force application point 55 to control the suction cup 10. The suction and discharge action, when the force applying point 55 applies a force to the bonding surface, and presses on the suction cup upper support frame 58, the driving lever 50 and the air stopping cushion 40 are activated, and the air is surrounded by the air vent 25 or the bonding surface 90. Discharge, and when the force application point 55 is pulled up, the tray 57 attached to the control rod 50 is driven to interlock the control rod 50 and the air stop pad 40, so that the outside air enters the suction cup 10 via the air inlet 20, and the suction cup 10 is generated. The internal and external pressures are the same and the adsorption force is lost. In addition, in this embodiment, a spring 60 or a gear 65 may be added to adjust the suction and discharge force of the suction cup 10 and determine the gas discharge in the suction cup 10 by the strength of the spring 60 or the gear 65. Exit location.

The invention can provide the user to easily change the position of the suction cup with one hand without any other equipment.
