Abstract

The invention is a variable suction cup device. The user holds the ventilation cover and continuously pushes down and pulls up together with the shaft and the piston. At this time, a vacuum is formed between the piston, the suction cup with a hole and the plane, and the vacuum The device and the plane can be fixed; the device can adjust the suction force by itself. The more the piston moves, the stronger the suction, the less the piston moves, the less the suction. The suction can be adjusted by the plane material, and it can be adjusted from zero suction.

Description

可變吸盤 variable suction cup

本發明係有關於一種吸盤，特別是有關於一種可自行調節吸力之吸盤。 The present invention relates to a sucker, in particular to a sucker with self-adjustable suction.

目前吸盤都是只有一種吸力，都是無法變化吸力之吸盤，並且如平面材質較於脆弱時，吸盤吸附後平面材質可能導致損壞。大多數吸盤只要使用經過一定時間損壞機率會增加，因每次吸附時都需按壓吸盤使空氣擠出，可能造成摩擦使吸盤部分破洞並造成無法形成真空。 At present, the suction cups have only one kind of suction force, which cannot be changed, and if the plane material is relatively fragile, the plane material may be damaged after the suction cup absorbs it. As long as most suction cups are used for a certain period of time, the probability of damage will increase, because each time the suction cup needs to be pressed to squeeze out the air, it may cause friction to make holes in the suction cup and make it impossible to form a vacuum.

有鑑於上述習知之問題，本發明的目的在於提供可自行調整吸力之吸盤。 In view of the above known problems, the purpose of the present invention is to provide a suction cup that can adjust the suction force by itself.

本發明的吸盤其可包括一活塞、一軸心、一有洞吸盤、一通風蓋。活塞連結於軸心。軸心具有一軸心孔，軸心孔內具有一閥芯、一閥芯桿、一彈簧片、一彈簧、一橡膠片，其中軸心連結於活塞和吸盤孔和通風蓋。有洞吸盤具有一吸盤孔，其中吸盤孔連結於軸心。通風蓋具有一通風孔，其中通風蓋連結於軸心。 The sucker of the present invention may include a piston, an axle, a sucker with holes, and a ventilation cover. The piston is connected to the shaft. The shaft center has an shaft center hole, and a valve core, a valve core rod, a spring leaf, a spring, and a rubber sheet are arranged in the shaft center hole, wherein the shaft center is connected to the piston, the sucker hole and the ventilation cover. The sucker with a hole has a sucker hole, wherein the sucker hole is connected to the shaft. The ventilation cover has a ventilation hole, wherein the ventilation cover is connected to the shaft.

活塞用於擠壓空氣使空氣從有洞吸盤排出至軸心孔。軸心用於連接活塞和吸盤孔和通風蓋，使裝置固定。軸心孔用於排出擠壓進孔內 之空氣，也用於排入空氣。上拉下壓用於使活塞擠壓空氣。有洞吸盤用於達成內部形成真空所需的空間。吸盤孔用於可與軸心固定。平面用於使裝置形成真空並使裝置固定，也用於使裝置進行分離。通風蓋可讓使用者較於方便握住裝置。通風孔用於可讓空氣吸入軸心孔，也用於讓空氣擠出軸心孔。閥芯用於使活塞擠壓時使空氣擠壓進軸心孔，也用於使空氣吸入進有洞吸盤。空氣擠出用於使有洞吸盤內部形成真空。空氣吸入用於使有洞吸盤內部消除真空。閥芯桿用於使閥芯上拉並使空氣吸入進有洞吸盤。上拉用於使空氣吸入進有洞吸盤。彈簧片用於固定閥芯左右，並使閥芯可上下移動，且可彈回原況，使空氣無法吸入進有洞吸盤。彈簧可使閥芯彈回原況。橡膠片使用本身橡膠之摩擦力讓閥芯和彈簧片固定。 The piston is used to squeeze the air to discharge the air from the holed suction cup to the shaft hole. The shaft is used to connect the piston with the suction cup hole and the vent cover to keep the unit fixed. Axle hole for discharge extrusion into the hole The air is also used to exhaust the air. Pulling up and pressing down is used to make the piston squeeze air. Suction cups with holes are used to achieve the space needed to create a vacuum inside. The suction cup hole is used to fix with the shaft. The planes are used to vacuum and hold the device, and also to allow separation of the device. The ventilation cover allows the user to hold the device more conveniently. Vent holes are used to allow air to be drawn into the axle hole and also to allow air to be forced out of the axle hole. The spool is used to squeeze air into the shaft hole when the piston is squeezed, and is also used to suck the air into the suction cup with holes. Air extrusion is used to create a vacuum inside the perforated suction cup. Air suction is used to remove the vacuum inside the perforated suction cup. The spool stem is used to pull the spool up and draw air into the holed suction cup. Pull-ups are used to draw air into the holed suction cups. The spring sheet is used to fix the valve core left and right, and the valve core can move up and down, and can bounce back to the original state, so that the air cannot be sucked into the sucker with holes. A spring allows the spool to spring back to its original state. The rubber sheet uses the friction of its own rubber to fix the valve core and the spring sheet.

軸心上拉下壓時，其中活塞、有洞吸盤、平面，透過空氣擠出形成真空區，與平面達成固定。閥芯桿上拉時，其中活塞、有洞吸盤、平面，透過空氣吸入消除真空區，可重平面拔起。 When the axis is pulled up and down, the piston, sucker with holes, and the plane are extruded through the air to form a vacuum area, and are fixed with the plane. When the spool rod is pulled up, the piston, sucker with holes, and the plane can be pulled up through the air suction to eliminate the vacuum area.

本發明之功效在於：可藉由調節吸力並避免平面損壞。可藉由不擠壓有洞吸盤，並延長吸盤壽命。可藉由軸心和活塞進行連續往下壓和往上拉而達成比一般吸盤還強之吸力。可藉由更換可變吸盤之零件而達成減省成本。可藉由不同消費者而指定可變吸盤上之握把位置，而客製化，並無固定之握把擺放方式。 The effect of the present invention is that the plane damage can be avoided by adjusting the suction force. By not squeezing the suction cup with holes, the life of the suction cup can be extended. It can achieve a stronger suction than ordinary suction cups by continuously pressing down and pulling up the shaft and piston. Cost savings can be achieved by replacing parts of the variable suction cup. The position of the grip on the variable suction cup can be specified by different consumers, and it can be customized, and there is no fixed way to place the grip.
