In this solution, the contact pressure transmitting member is integral with the suction base, and the contact pressure transmitting member is consistent with the material of the suction base, and is soft elastic. The material is pressed directly onto the soft contact pressure transmitting member during use. Due to the large deformation of the contact pressure transmitting member during the pressing process, the pressure of the pressing member to adsorb the suction base on the fixed surface will be Greatly discounted, so the suction of the suction cup is still not strong enough, there is still room for improvement.

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

detailed description

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

Example 1:

As shown in FIG. 1 to FIG. 7 , a suction cup with strong adsorption force comprises an elastic platen body 1 , a skeleton 2 is arranged in the platen body 1 , and a connecting rod 3 is arranged on the back of the frame 2 . The back of the skeleton 2 is further provided with a plurality of protrusions and exposed on the upper surface of the platen body 1, and the connecting rod 3 is sleeved with a suction cup cover 5 directly pressed against the convex ribs 4, The back side of the suction cup cover 5 is provided with a pressing member 6 which is pressed against the back of the suction cup and connected to the connecting rod 3. In the suction cup field, the platen body 1 is generally made of TPE rubber material, the rib 4 and the frame 2 are generally made of polyphenylene ether material, and the hardness of the rib 4 and the frame 2 is higher than that of the platen body 1. In the process of using the suction cup, the top of the pressing member 6 cooperates with the connecting rod 3 to press the suction cup cover 5 downward, the convex rib 4 is hard, and the hardness thereof is larger than the hardness of the pressing plate body 1, so when the suction cup cover 5 When directly pressed against the rib 4, the rib 4 is less deformed, so that the pressure of the suction cup cover 5 is transmitted to the platen body 1 with maximum capacity, so that the platen body 1 is tightly adsorbed on the adsorption surface such as a wall. Strong adsorption capacity, and long-lasting adsorption will not loosen.

The upper surface of the rib 4 is higher than the upper surface of the platen body 1, so that the pressure of the suction cup cover 5 is all applied to the rib 4, and the rigid contact between the two can transmit the pressure to the platen body. On the 1st, the platen body 1 is adsorbed on the adsorption surface such as a wall, and the adsorption is more durable.

The distance H between the upper surface of the rib 4 and the upper surface of the platen body 1 is less than or equal to 0.8 mm. When H is greater than 0.8 mm, since the rib 4 is higher than the upper surface of the platen body 1, when the suction cup cover 5 applies pressure to the rib 4, the rib 4 is easily bent and deformed to the side, which is disadvantageous to the pressure to the pressure plate. The direct transfer on the body 1 is such that the distance between the rib 4 and the upper surface of the platen body 1 is preferably set to 0.8 mm or less.

The ribs 4 extend in the radial direction of the skeleton 2, so that the injection molding liquid flowing from the middle to the outside of the skeleton 2 during the injection molding process of the skeleton 2 is more fluid, and can be quickly filled into the radial convex. In the rib cavity, the production efficiency of the suction cup is further increased, and the rib 4 provided on the back of the skeleton 2 is radial, the contact area of the suction cup cover 5 with the rib 4 is larger, and the pressure of the suction cup cover 5 is all It is transmitted to the platen body 1, so that the suction capacity of the suction cup is stronger and the adsorption is more durable.

At least one sealing ring 7 is provided on the surface of the platen body 1 that is in contact with the adsorption surface. When the suction cup is adsorbed on the adsorption surface of the wall or the like, the sealing ring 7 is provided to more effectively prevent the outside air from entering the vacuum chamber formed when the suction cup is used, thereby improving the vacuum degree, making the suction force of the suction cup stronger and the adsorption more durable. When the number of the seal rings 7 is plural, the seal rings 7 are arranged on the platen body 1 in a concentric manner one by one.

When the suction cup is sucked, the positional relationship between the rib 4 and the seal ring 7 is that the rib 4 is pressed against the seal ring 7, so that the seal ring 7 is subjected to a large pressure because the rib 4 is hard, and the seal is more secure. The tightness between the ring 7 and the adsorption surface ensures that the vacuum chamber formed by the drawing vacuum does not leak.

A plurality of open slots 8 are defined from the outer edge of the frame 2 toward the center thereof, and are disposed on the frame 2 and located between the slot bottom 81 of the open slot 8 and the connecting rod 3 for improving The through hole 9 of the skeleton 2 is elastically deformable, and the through hole 9 is a circular hole, and the through hole 9 may also be a strip hole. Therefore, when the suction cup is used for drawing vacuum, the elastic deformation ability of the portion of the skeleton 2 which is located outside the connecting rod 3 becomes stronger, and the deformation is more likely to occur than the conventional skeleton, and it is also easy to elastically recover. Therefore, when the suction cup is used for pulling vacuum It can ensure that the skeleton 2 is not broken, which makes vacuuming easier, and the vacuum chamber generated by the skeleton 2 driving the pressure plate body 1 is sufficiently large, and the vacuum degree is sufficiently high, which greatly enhances the adsorption capacity of the suction cup. Moreover, the densely arranged through holes 9 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 5 to the pressure plate body 1 is better completed, so that the adsorption capacity of the suction cup is stronger and the adsorption is more durable.

The length of the opening groove 8 is less than 1/2 of the radius of the platen body 1, so that the length of the arm 82 formed between the adjacent opening grooves 8 is short, and the arm 82 can be prevented from being pulled off when the suction cup draws a vacuum. To extend the life of the suction cup. Since the length of the arm 82 between the adjacent opening grooves 8 is short due to the short opening groove 8, the skeleton 2 has a good elastic deformation ability when the vacuum is drawn, and the shorter arm 82 makes the outer side of the skeleton 2 The rigidity is enhanced, and the pressure plate body 1 can be well supported, and the pressure can be better transmitted when the suction cup cover 5 applies pressure. The connecting rod 3 is a screw, and the pressing member 6 is a nut. When the nut is engaged with the screw, the middle portion of the skeleton 2 is pulled up, and the outer side of the skeleton 2 is subjected to the pressure of the suction cup cover 5, so the suction cup cover 5 The platen body 1 is pressed against a suction surface such as a wall by the skeleton 2, and a central portion of the platen body 1 forms a vacuum chamber.

Example 2:

As shown in FIG. 8 to FIG. 10, the difference between Embodiment 2 and Embodiment 1 is that: The rib 4 extends to the outer end of the frame 2, and the rib 4 has a rounded transition. The pressing member 6 is engaged with the connecting rod 3, and the pressing member 5 cooperates with the connecting rod 3 when the suction cup is used. The platen body 1 is pressed onto the adsorption surface. Since the ribs 4 extend all the way to the outer end of the frame 2, the suction cup cover 5 can maintain sufficient rigid contact with the ribs 4, and the suction cup cover 5 does not directly contact the pressure plate body. In the case of the soft colloid of 1, the suction cup cover 5 can transmit all the pressure to the platen body 1, and the platen body 1 is more strongly adsorbed on the adsorption surface such as the wall, and the adsorption is more durable.
