Description

a suction cup with good adsorption effect

Technical field

The present invention relates to a suction cup, and more particularly to a suction cup having a good adsorption effect.

Background technique

Because of its convenient use, the suction cup can be widely used only by pressing on a base surface such as a wall and without drilling a wall. The current suction cups are generally covered with an elastic colloid on the skeleton, and the suction cup cover is then covered on the elastic colloid. When the suction cup is used, the pressing member cooperates with the connecting rod to apply pressure to the suction cup cover, thereby pressing the elastic colloid onto the adsorption surface. For a flat skeleton suction cup, when the suction cup cover applies pressure to the elastic colloid, the middle portion of the elastic colloid is pulled up with the skeleton to form a vacuum chamber; and for the arch skeleton suction cup, when the suction cup cover applies pressure to the elastic colloid, The middle part of the elastic colloid is pressed down with the skeleton, so that the original arched skeleton will be flattened, so the elastic colloid is uniformly adsorbed onto the adsorption surface. Therefore, whether it is a flat skeleton suction cup or an arched skeleton suction cup, the skeleton functions to support the elastic colloid and transmit pressure, but the elastic deformation ability of the conventional skeleton is poor, and in the process of vacuuming or pressing the suction cup, the skeleton is The outer portion of the connecting rod is hard to be elastically deformed, which makes the suction cup vacuum or pressed. If the pressing member and the connecting rod are combined to generate a large pulling force for vacuuming, the skeleton is easily broken; if forced Pressing the arched skeleton is also easy to break the skeleton, so it is easy to lose the function of the suction cup; in addition, the length of the open groove from the outer edge to the center of the conventional skeleton generally reaches half the radius of the elastic colloid or even More than half, so the length of the arm between adjacent open slots is longer Long, when the suction cup is pulled vacuum or pressed, the arm between the open slots on the skeleton is easily broken in the elastic colloid, so that the suction cup loses the function of adsorption; further, because the length of the arm between the open slots is longer Long, so the elasticity of the entire skeleton is poor, which is not conducive to the elastic recovery of the skeleton. Moreover, the rigidity of the outer side of the skeleton is poor. When the suction cup cover applies pressure to the elastic colloid, the arms on the outer side of the skeleton are easily deformed, which is not conducive to the elastic colloid. Support, which in turn affects the suction capacity of the suction cup.

Therefore, the present invention has been made based on the above deficiencies.

The suction cup with good adsorption effect as described above is characterized in that: the through hole is three turns, the number of through holes in the innermost ring is 12, and the number of through holes in the middle one is 18, most The number of through holes in the outer ring is 24.

Compared with the prior art, the present invention has the following advantages:

1. The suction cup of the invention has a good adsorption effect and has a skeleton on the outer side of the connecting rod. A closed region that extends to the outer edge of the skeleton with a through hole in the closed region. Since the through hole is provided in the closed region, the elastic deformation ability of the skeleton becomes stronger, the deformation is more likely to occur than the conventional skeleton, and the elastic recovery is also easy. Therefore, the suction cup can ensure that the skeleton does not pull when vacuuming or pressing. Broken or broken, the flat skeleton suction cup is easier to vacuum, and the vacuum chamber generated by the skeleton to drive the pressure plate body is large enough, the vacuum is high enough, and the suction capacity of the suction cup is greatly enhanced, and the arched skeleton suction cup can make The arched skeleton has sufficient deformation to make the elastic colloidal shape flatter. Therefore, whether it is the flat skeleton used for vacuuming the suction cup or the arched skeleton used for pressing the suction cup, as long as the above-mentioned through holes are provided, the deformation ability is improved, and the suction capacity of the suction cup is enhanced. Moreover, the arranged through holes increase the contact area of the skeleton when combined with the platen body, so that the two are more closely connected, so that the skeleton can better support the platen body and better complete the suction cup cover. The pressure transmission to the pressure plate body makes the adsorption capacity of the suction cup stronger and the adsorption is more durable.

2. Another skeleton of the suction cup of the present invention has a closed area on the skeleton and on the outer side of the connecting rod, and the radius of the closed area is at least 1/2 of the radius of the skeleton, and is disposed in the closed area. There is a through hole, and a plurality of open slots are formed in the closed area and extending from the outer edge of the skeleton toward the center thereof. Since the closed area is provided with a through hole, and the closed area is provided with an open groove, the elastic deformation ability of the skeleton becomes stronger, deformation is more likely to occur than the conventional skeleton, and elastic recovery is also easy, and therefore, the suction cup is pulled or vacuumed. When pressed, it can ensure that the skeleton will not be broken or broken, and the flat skeleton suction cup can be vacuumed more easily, and the vacuum chamber generated by the skeleton to drive the pressure plate body is large enough, the vacuum degree is high enough, and the suction of the suction cup is greatly enhanced. The ability, while the arched skeleton suction cup can make the arched skeleton deform enough to make the elastic colloid shape more flat. Moreover, the arrangement of through holes and settings The opening groove increases the contact area of the skeleton when combined with the platen body, so that the two are connected more closely. Therefore, the skeleton can better support the pressure plate body, and the suction cup cover is better completed. The pressure transmission of the body makes the suction capacity of the suction cup stronger and the adsorption is more durable.

3. The length of the open slot of the present invention is less than 1/2 of the radius of the platen body. Therefore, the length of the arm between adjacent open slots is short, which can prevent the arm from being pulled off when the suction cup pulls the vacuum, and the length of the suction cup is extended. Service life. Since the shorter opening groove realizes the shorter length of the arm between the adjacent open slots, the skeleton has good elastic deformation ability when pulling vacuum or pressing, and the shorter arm enhances the rigidity of the outer side of the skeleton. The pressure plate body is well supported, and the suction cup cover can transmit pressure better when pressure is applied.

detailed description

The present invention is further described below in conjunction with the accompanying drawings:

As shown in FIG. 1 to FIG. 8, a suction cup with good adsorption effect comprises an elastic platen body 1 and a connecting rod 3 disposed on the back of the frame 2, and has a closed on the frame 2 and outside the connecting rod 3. In the region 4, the radius of the closed region 4 is at least 1/2 of the radius of the skeleton 2, and the through hole 5 is arranged in the closed region 4, and the through hole 5 is circumferentially arrayed on the closed region 4, A plurality of open slots 6 are defined in the closed region 4 and extending from the outer edge of the skeleton 2 toward the center thereof. Since the radius of the closed region 4 is larger than 1/2 of the radius of the skeleton 2, and the through hole 5 is densely disposed in the closed region 4, and the open groove 4 is provided in the closed region 4, the elastic deformation ability of the skeleton 2 becomes stronger, which is more conventional. The skeleton is more susceptible to deformation and is also elastically resilience. Therefore, the suction cup can ensure that the skeleton 2 does not break or break when pulling vacuum or pressing, and the flat skeleton suction cup is easier to evacuate, and the skeleton 2 can be driven. The vacuum chamber generated by the deformation of the disk body 1 is large enough, the vacuum degree is sufficiently high, and the adsorption capacity of the suction cup is greatly enhanced, and the arched skeleton suction cup can make the arch skeleton sufficiently Deformation makes the elastic gel shape more flat. Moreover, the arranged through hole 5 and the plurality of open slots 6 provided increase the contact area of the frame 2 when combined with the platen body 1, thereby making the two connections closer together, so that the frame 2 can be better realized. The support of the platen body 1 better completes the pressure transmission of the suction cup cover 7 to the platen body 1, so that the suction capacity of the suction cup is stronger and the adsorption is more durable.

The length of the open groove 6 is less than 1/2 of the radius of the platen body 1. Therefore, the length of the arm 62 formed between the adjacent opening grooves 6 is short, and it is possible to prevent the arm 62 from being pulled or broken when the suction cup is pulled or pressed, thereby prolonging the service life of the suction cup. Since the shorter length of the opening groove 6 enables the length of the arm 62 between the adjacent opening grooves 6 to be short, the skeleton 2 has a good elastic deformation ability when pulling vacuum or pressing, and the shorter arm 62 makes the skeleton 2 The rigidity of the outer side is enhanced, and the pressure plate body 1 can be well supported, and the pressure can be better transmitted when the suction cup cover 7 applies pressure.

The number of the open slots 6 is at least three. The number of the open slots 6 on the bobbin 2 is preferably set to at least three, because when the number of the open slots 6 is less than three, the width of the arms 62 between the adjacent open slots 6 is wide, and thus The elastic deformation ability of the outer side of the skeleton 2 is deteriorated, and the requirement for elastic deformation of the skeleton 2 when the vacuum is drawn by the suction cup cannot be satisfied.

The through hole 5 is a circular hole (as shown in FIG. 4). Of course, the through hole 5 may also be a combination of a circular hole and a strip hole (as shown in FIG. 8) or only a strip hole.

The through holes 5 are arranged on the bobbin 2 in a plurality of turns, and each of the through holes 5 is circumferentially arranged on the bobbin 2.

The number of through holes 5 per turn is 4 to 8 more than the number of one through holes 5 on the inner side adjacent thereto. If the number of through holes in the outer ring is more than 8 more than the number of through holes in the inner ring adjacent thereto, the through holes 5 of the adjacent inner and outer rings are too dense, affecting the mechanical strength of the skeleton 2, and pulling the vacuum Or when pressing, the skeleton 2 may be broken from the outer ring through hole to the inner ring through hole, and the elastic deformation of the skeleton 2 when the outer ring through hole is more than the number of the inner ring through holes smaller than four The ability is not optimal. As shown in FIG. 4, the through hole 5 is three turns, the number of the through holes 5 of the innermost ring is 12, and the number of the through holes 5 in the middle one is 18, and the through hole of the outermost ring The number of 5 is 24, which optimizes the elastic deformation ability of the skeleton 2 while also ensuring the mechanical strength of the skeleton 2, enabling it to better support the platen body 1 and better transmit pressure.

An upwardly convex rib 8 is disposed on the frame 2 and on both sides of the opening groove 6. The longitudinal direction of the rib 8 extends in the radial direction of the frame 2, and the rib 8 extends to The outer edge of the skeleton 2 or the outer end of the skeleton 2, where the male rib 8 extends to the outer end of the skeleton 2 means that the outer side of the rib 8 is close to the outer side of the skeleton 2, but away from the outer side of the skeleton 2 There is a distance of about 2 mm to 10 mm, that is, a vacancy 20 is formed between the outer side of the skeleton 2 and the outer side of the rib 8, and there are no raised ribs on the vacancy 20. Since the ribs 8 are arranged radially along the skeleton 2, the injection molding liquid flowing from the middle to the outside of the skeleton 2 during the injection molding process is more fluid, and can be quickly filled into the radial rib cavity. Further, the production efficiency of the suction cup is higher, and the ribs 8 provided on the back of the skeleton 2 are radial, the corresponding area of the suction cup cover 7 and the ribs 8 in space is larger, and the pressing member 9 is opposite to the suction cup cover 7. The pressure will be transmitted to the platen body 1, so that the suction capacity of the suction cup is stronger and the adsorption is more durable.

Another suction cup embodiment with good adsorption effect is as follows:

As shown in FIG. 9, another suction cup having good adsorption effect comprises a skeleton 2 and a connecting rod 3 disposed on the back of the skeleton 2, and has a closed region 4 on the skeleton 2 and outside the connecting rod 3, The closed area 4 extends to the outer edge of the skeleton 2, and a through hole 5 is formed in the closed area 4, and the through hole 5 is a circular hole. The skeleton 2 is a flat skeleton. Since the closed region 4 extends to the outer edge of the skeleton 2, and the through hole is densely formed in the closed region 4, the elastic deformation ability of the skeleton 2 becomes stronger, deformation is more likely to occur than the conventional skeleton, and elastic recovery is also easy. When the suction cup is used, the suction cup can ensure that the skeleton does not break, the vacuum is easier, and the vacuum chamber generated by the skeleton 2 driving the pressure plate body 1 is large enough, the vacuum is high enough, and the suction of the suction cup is greatly enhanced. ability. Moreover, the densely arranged through holes 5 increase the contact area of the frame 2 when combined with the platen body 1, so that the two are more closely connected, and therefore, the frame 2 can better support the platen body 1, The pressure transmission of the suction cup cover 7 to the pressure plate body 1 is better accomplished, so that the adsorption capacity of the suction cup is stronger and the adsorption is more durable.

Another suction cup embodiment 2 with good adsorption effect:

As shown in FIG. 10, the difference between the embodiment 2 and the first embodiment is that the skeleton 2 is an arched skeleton for pressing the suction cup, and the through hole 5 is a strip hole. Since the closed region 4 extends to the outer edge of the skeleton 2, and the through hole is densely formed in the closed region 4, the elastic deformation ability of the skeleton 2 becomes stronger, deformation is more likely to occur than the conventional skeleton, and elastic recovery is also easy. The suction cup can ensure that the skeleton does not break when pressed, and the arch skeleton has sufficient deformation to make the elastic colloid shape flatter. Moreover, dense The through hole 5 arranged by the hemp increases the contact area of the skeleton 2 when combined with the platen body 1, so that the two are connected more closely, and therefore, the frame 2 can better support the platen body 1, and The pressure transmission of the suction cup cover 7 to the pressure plate body 1 is completed well, so that the suction capacity of the suction cup is stronger and the adsorption is more durable.
