Description
本創作係為一種吸盤，尤指一種真空吸盤。This creation is a suction cup, especially a vacuum suction cup.
目前比較常見的真空吸盤，都是為了在瓷磚、玻璃等平坦表面上懸掛毛巾、浴巾等物品所設置的掛設件。一般的吸盤掛設件係由掛件和吸盤組成，所述掛件可以用於掛毛巾、浴巾和衛生紙等物品，而吸盤可吸附於平坦的表面上，如玻璃、瓷磚等。At present, the most common vacuum suction cups are hanging parts for hanging towels, bath towels and the like on flat surfaces such as tiles and glass. A typical suction cup hanging member is composed of a hanging member and a suction cup which can be used for hanging towels, bath towels and toilet paper, and the suction cup can be attached to a flat surface such as glass, ceramic tile or the like.
真空吸盤的吸附片在接觸到光滑或平坦的吸附面時，其吸附片與吸附面之間沒有空氣，而吸附片中心朝向安裝表面的反方向拉伸，使吸附片與吸附面之間產生真空負壓，使得真空吸盤牢牢地吸附在吸附面上，而拉伸動作是透過吸附片配合其它附件完成。When the adsorption sheet of the vacuum chuck contacts the smooth or flat adsorption surface, there is no air between the adsorption sheet and the adsorption surface, and the center of the adsorption sheet is stretched in the opposite direction of the mounting surface, so that a vacuum is generated between the adsorption sheet and the adsorption surface. The negative pressure makes the vacuum suction cup firmly adhere to the adsorption surface, and the stretching action is completed by the adsorption sheet and other accessories.
一般而言，將真空吸盤的吸附片與安裝表面之間形成真空負壓的方法有很多種，如：以拉力將吸附片拉成真空固定、以推力將吸附片推成真空固定、或以壓空氣壓所形成的真空固定，但是一般為了保持所述真空吸盤的吸附狀態，需要搭配單獨設計的附件來增加吸力。Generally, there are various methods for forming a vacuum negative pressure between the adsorption sheet of the vacuum chuck and the mounting surface, such as: pulling the adsorption sheet into a vacuum by pulling force, pushing the adsorption sheet into a vacuum by thrust, or pressing The vacuum created by the air pressure is fixed, but generally in order to maintain the adsorption state of the vacuum chuck, it is necessary to use a separately designed accessory to increase the suction force.
例如以推方式形成真空的真空吸盤為例，推方式真空吸盤的吸附片和吸附面之間存在較難以吸附固定的問題，而且吸附面和吸附片之間的吸附力也不夠，容易脫落，無法較長時間吸附真空吸盤，使得脫落後要反復吸附，導致使用上的不便。For example, a vacuum chuck that forms a vacuum by pushing is taken as an example. There is a problem that it is difficult to adsorb and fix between the adsorption sheet of the vacuum chuck and the adsorption surface, and the adsorption force between the adsorption surface and the adsorption sheet is not enough, and it is easy to fall off. The vacuum chuck is adsorbed for a long time, so that it is repeatedly adsorbed after falling off, resulting in inconvenience in use.
如中國專利CN101793280A所揭示的一種真空吸附器，該真空吸附器係由蓋子，高度調整附件和吸附片組成，所述蓋子可順時針方向旋轉，所述蓋子使其內側固定片沿所述高度調整附件的高度調整斜面滑動，上述蓋子也隨著斜面逐步提升，當所述蓋子內側固定片到達高度調整附件的凹槽內後，吸附片也提升到一定高度。吸附片的外周緣緊貼在吸附面上，藉此隨著吸附片之中央部位的提升，使得吸附片和吸附面間成為真空狀態，藉此固定吸附在吸附面上。A vacuum adsorber, as disclosed in Chinese Patent No. CN101793280A, consisting of a cover, a height adjustment attachment and an adsorption sheet, the cover being rotatable in a clockwise direction, the cover adjusting the inner fixing piece along the height The height adjustment of the attachment slides, and the cover is gradually raised with the inclined surface. When the inner fixing piece of the cover reaches the groove of the height adjustment attachment, the adsorption piece is also raised to a certain height. The outer peripheral edge of the adsorption sheet is in close contact with the adsorption surface, whereby the adsorption portion and the adsorption surface are brought into a vacuum state as the central portion of the adsorption sheet is lifted, thereby being fixedly adsorbed on the adsorption surface.
如上所述，由於蓋子的旋轉，蓋子內側固定片沿著高度調整附件的高度調整斜面滑動，蓋子順著斜面逐步提升，也就是蓋子與高度調整附件之間推出一定距離，使得蓋子與高度調整附件之間有了間隙，從而使高度調整附件與吸附片緊貼，因蓋子內中心鉤子鉤住吸附片的中心柱子，從而隨著蓋子的提升，吸附片的中心柱子也隨著提升，吸附片與吸附面之間產生真空吸力。而這種真空吸盤，蓋子與高度調整附件有一定間隙，使其受外力影響較大，如果向外拉動蓋子，蓋子與高度調整附件之間的單邊會增大間隙，感覺不牢固，不美觀，而且還會產生高度調整附件之斜面上的凹槽與蓋子的內側固定片脫離的情形，使得高度調整附件無法壓緊吸附片的邊緣造成漏氣而使吸盤脫落。As described above, due to the rotation of the cover, the inner fixing piece of the cover slides along the height adjustment of the height adjusting attachment, and the cover is gradually raised along the inclined surface, that is, a certain distance is pushed between the cover and the height adjusting attachment, so that the cover and the height adjusting attachment are attached. There is a gap between them, so that the height adjustment attachment is in close contact with the adsorption piece, because the central hook in the cover hooks the central column of the adsorption piece, so that as the cover is lifted, the central column of the adsorption piece is also lifted, and the adsorption piece and the adsorption piece are Vacuum suction is generated between the adsorption faces. The vacuum suction cup has a certain gap between the cover and the height adjustment attachment, so that it is greatly affected by the external force. If the cover is pulled outward, the single side between the cover and the height adjustment attachment will increase the gap, and the feeling is not firm and unattractive. Moreover, the groove on the inclined surface of the height adjustment attachment is separated from the inner fixing piece of the cover, so that the height adjustment attachment cannot press the edge of the adsorption piece to cause air leakage and the suction cup is detached.
而且上述的推力真空吸盤必須在吸附片一次性裝配完成後才能進行測試，如測試時發現為不合格產品後，再拆卸就容易造成產品的損壞，造成浪費。Moreover, the above-mentioned thrust vacuum suction cup must be tested after the one-time assembly of the adsorption sheet is completed. If the product is found to be unqualified after the test, the disassembly may easily cause damage to the product and cause waste.

The bottom end of the peripheral wall 102 is located above the edge of the adsorption sheet 30. The inner side of the top surface 101 is further provided with a fixing piece 12 extending vertically downward and uniformly distributed along a circumference, and the fixing piece 12 corresponds to the recessed hole 13 in the height adjusting member 16, and is engaged with In the recessed hole 13, the recessed hole 13 is further sleeved on the outer side of the fixing piece 12 and moves up and down along the fixing piece 12 along with the rotation of the cover 10. With the rotation of the cover 10, the cover drives the height adjusting member 16 to rotate at the same time, and at the same time, the connecting piece 11 of the height adjusting member 16 is moved along the height adjusting inclined surface 22 of the pressure seat 20 from the bottom end of the inclined surface to the highest end until The connecting piece 11 is moved to the limiting recess 18 between the highest end of the height adjusting inclined surface 22 and the height limiting column 15 on the pressure seat 20, and the connecting piece 11 is engaged with the limiting recess 18, and at this time, due to the action of the height limiting column 15 The cover 10 cannot be rotated, and the height adjusting member 16 is moved to the highest position at this time, and the curved elastic piece 23 connected to the connecting piece 11 is also pressed downward to the maximum elastic force due to the pressing of the inner side surface of the cover 10 to form a positioning. The central portion of the adsorption sheet 30 is lifted off the adsorption surface with the height adjustment member 16 as the height adjustment member 16 is lifted, and the periphery of the adsorption sheet 30 is pressed against the pressure seat 20 by the pressure seat 20. On the surface, the center of the adsorption sheet 30 is separated from the adsorption surface and a vacuum negative pressure is generated between the adsorption surface and the adsorption surface, and suction is generated to adsorb the vacuum chuck to the adsorption surface.
當需要將該真空吸盤從吸附面上拆卸下來時，只要逆方向轉動蓋子10，使得連接片11從高度調整斜面22之最高端側的限位凹部18中脫離，隨著高度調整附件16的弧形彈片23彈力作用，連接片11可沿高度調整斜面22從最高端運動至最低端，直到回到初始狀態，高度調整件16回復到原位，此時吸附片30的中心部分也回復至原位與吸附面相貼合，此時真空負壓解除，真空吸盤可與吸附面分離取下。When it is necessary to detach the vacuum chuck from the adsorption surface, as long as the cover 10 is rotated in the reverse direction, the connecting piece 11 is detached from the limiting recess 18 of the highest end side of the height adjusting inclined surface 22, and the arc of the attachment 16 is adjusted with the height. The elastic piece 23 is elastically actuated, and the connecting piece 11 can be moved from the highest end to the lowest end along the height adjusting inclined surface 22 until returning to the initial state, and the height adjusting member 16 returns to the original position, at which time the central portion of the adsorption piece 30 is also restored to the original state. The position is adhered to the adsorption surface, and at this time, the vacuum negative pressure is released, and the vacuum suction cup can be separated from the adsorption surface.
因為吸附片30中間的鉤子32勾住高度調整件16中間之圓孔161的邊緣，故其會隨著高度調整件16升高，並可能造成鉤子32與圓孔161邊緣的鉤環35之間的脫離，即高度調整件16與鉤子32可能造成拉脫，因此在鉤子32與其內側的中心柱39之間設置一止脫環25，該止脫環25從鉤子32的內側向外頂住鉤子32，使鉤子32與高度調整件16中心的圓孔161邊緣緊密配合，並且該止脫環25具有三個突部251卡合於鉤子32之間，使鉤子32相對於高度調整件16不會左右轉動，即使在運動時也不會相互脫離。Since the hook 32 in the middle of the suction sheet 30 hooks the edge of the circular hole 161 in the middle of the height adjusting member 16, it rises with the height adjusting member 16, and may cause the hook 32 and the hook ring 35 at the edge of the circular hole 161 to be formed. The detachment, that is, the height adjusting member 16 and the hook 32 may cause a pull-off, so that a stop ring 25 is provided between the hook 32 and the inner center post 39 thereof, and the retaining ring 25 bears the hook outward from the inner side of the hook 32. 32, the hook 32 is tightly fitted to the edge of the circular hole 161 at the center of the height adjusting member 16, and the retaining ring 25 has three projections 251 engaged between the hooks 32 so that the hook 32 does not oppose the height adjusting member 16 Rotate left and right and do not disengage from each other even when exercising.
綜上所述，本創作之真空吸盤其不但結構緊密，而且易於裝配和安裝，不易損壞，亦能夠長時間保持吸附片與吸附面之間的真空狀態，使真空吸盤即使長時間黏附在吸附面上也不會出現漏氣情形而造成吸盤的脫落，有效保持吸力的持久性。In summary, the vacuum chuck of the present invention is not only compact in structure, but also easy to assemble and install, is not easy to damage, and can maintain the vacuum state between the adsorption sheet and the adsorption surface for a long time, so that the vacuum suction cup adheres to the adsorption surface even for a long time. There is also no air leakage on the upper side, causing the suction cup to fall off, effectively maintaining the durability of the suction.
