Description

Technical Field

[0001] The utility model relates to the technical field of suction cups, in particular to a magnetic vacuum suction cup device with high load-bearing capacity. Background Art

[0002] Vacuum suction cups, also known as vacuum slings, are one of the actuators of vacuum equipment. Generally speaking, using vacuum suction cups to grab products is the cheapest way. Vacuum suction cups are of various types. Rubber suction cups can be operated at high temperatures, silicone rubber suction cups are very suitable for grabbing products with rough surfaces, and polyurethane suction cups are very durable. In addition, in actual production, if the suction cup is required to be oil-resistant, you can consider using polyurethane, nitrile rubber or vinyl-containing polymers to make the suction cup.

[0003] When grabbing smooth products, magnetic suction cups are often used for grabbing. The existing magnetic suction cups mainly achieve the adsorption effect through magnets. The magnets are generally a group, and the suction force can bear a few kilograms. The grabbing force of this suction cup is low and cannot cope with a variety of usage scenarios, resulting in certain inconveniences in use. Based on this, we propose a high-load-bearing magnetic vacuum suction cup device. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: the structure forms a vacuum through the magnetic attraction of the permanent magnet and the inner structure, and installs a pulling structure or a vacuum pipe through the metal ring and the threaded groove on the inner side of the middle inner dividing plate. When pulling, the metal ring drives the upper body of the fixed cylinder and drives the top of the suction cup shell to deform, so that the reinforced ribs and hollow ribs on the inner side of the inner dividing plate produce flexible deformation, and then the convex points and the smooth surface retract under air pressure to cooperate with the internal deformation to form a vacuum structure to lift the grasped object, while the support column and the reinforcement column on the outer side of the inner dividing plate form an outer supporting structure, and cooperate with the magnetic attraction of the permanent magnet to increase the bearing capacity of the outer side, and the outer edge of the soft chassis is also provided with a sealed outer edge vacuum Empty structure, the whole structure can make full and maximum use of magnetic force, and cooperate with the overall vacuum structure to make the adsorption bearing capacity of the whole suction cup reach about 30 kg. It has a wide range of application scenarios. Metal surfaces such as cars and ships that need to adsorb external equipment have high bearing capacity without drilling holes, and the internal structure increases the bearing capacity and structural strength, so that the weighing effect is good and the lifting efficiency is high. Through the permanent magnet and hole slots, the N and S poles of the permanent magnet are cross-arranged to stabilize the magnetic attraction, facilitate auxiliary magnetic grabbing, and increase the stability of the structure.

[0012] By setting the hollow ribs and guide holes, after the suction cup shell is lifted by the fixing tube and the metal ring, the guide holes and the hollow ribs cause the structure on the inner side of the inner dividing plate to deform so that the airflow can be discharged. The bottom of the soft chassis is vacuumed by the deformation and retraction of the convex points to increase the adsorption force. This setting increases the force strength and allows the structure to cope with the operation scenarios of lifting and vacuuming, thereby increasing the overall adaptability and adapting to different operation equipment.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-Figure 4The utility model provides a technical solution: a high-load-bearing magnetic vacuum suction cup device, comprising a suction cup shell 1, an inner partition plate 12 is fixedly installed inside the suction cup shell 1, a plurality of support columns 9 are fixedly installed on the opposite sides of the inner partition plate 12 and the suction cup shell 1, a magnet installation groove 16 is opened inside the support column 9, a hole groove 17 is opened inside the support column 9, a permanent magnet 11 is fixedly installed inside the magnet installation groove 16, a plurality of reinforcement columns 10 are fixedly installed outside the support column 9, and a soft bottom plate 5 is fixedly installed on the bottom of the suction cup shell 1 and the inner partition plate 12 A sealing outer edge 8 is fixedly installed on the outer side of the bottom of the soft chassis 5, two protrusions 6 are fixedly installed on the bottom of the soft chassis 5, two fixed tubes 2 are fixedly installed inside the suction cup shell 1, metal rings 3 are fixedly installed inside the tops of the two fixed tubes 2, and a threaded groove 4 is opened on the inner side of the metal ring 3, two support tubes 13 are fixedly installed on the inner side of the inner dividing plate 12, a plurality of hollow ribs 15 are fixedly installed inside the inner dividing plate 12, a reinforcing rib 14 is fixedly installed on the inner side of the inner dividing plate 12, and a plurality of guide holes 18 are opened on the inner sides of the two fixed tubes 2.

[0020] The working principle of the above technical solution is as follows: through the magnetic attraction of the permanent magnet 11 and the vacuum formed by the inner structure, and the lifting structure or vacuum pipe is installed through the metal ring 3 and the threaded groove 4 on the inner side of the middle inner dividing plate 12. When lifting, the metal ring 3 drives the upper body of the fixed cylinder 2 and drives the top of the suction cup shell 1 to deform, so that the reinforcement rib plate 14 and the hollow rib plate 15 on the inner side of the inner dividing plate 12 produce flexible deformation, and then the convex point 6 and the smooth surface retract under air pressure to cooperate with the internal deformation, forming a vacuum structure to lift the grasped object, while the outer side of the inner dividing plate 12 The support column 9 and the reinforcement column 10 form an outer supporting structure, and cooperate with the magnetic attraction of the permanent magnet 11 to increase the bearing capacity of the outside. The outer edge of the soft chassis 5 is also provided with a sealed outer edge 8 vacuum structure. The whole structure can fully and maximize the use of the magnetic force. At the same time, with the overall vacuum structure, the adsorption bearing capacity of the whole suction cup reaches about 30 kilograms. The application scenarios are relatively wide. The metal surface of automobiles, ships, etc. that need to adsorb external equipment has a high bearing capacity without drilling holes, and the internal structure increases the bearing capacity and structural strength, so that the weighing effect is good and the lifting efficiency is high.

[0021] In another embodiment, Figure 1-Figure 4 As shown, the support column 9 is evenly and symmetrically distributed inside the suction cup shell 1 in a rectangular linear shape, and the reinforcement column 10 includes a reinforcement horizontal column and a reinforcement vertical column, and the reinforcement horizontal column and the reinforcement vertical column are evenly distributed on the opposite sides of the suction cup shell 1 and the inner dividing plate 12, and the end of the reinforcement column 10 away from the support column 9 is fixedly installed on the inner side of the inner dividing plate 12 and the suction cup shell 1 respectively.

[0022] The arrangement of the reinforcement column 10 and the support column 9 can increase the structural strength and the torque required for deformation on the opposite sides of the inner dividing plate 12 and the suction cup shell 1, so that the torque is greater than the torque required for the inner deformation of the inner dividing plate 12, making it easier for the inner side of the structure to deform during lifting to form a vacuum extraction effect, while increasing the overall force strength and indirectly increasing the load force for lifting.

[0023] In another embodiment, Figure 3 and Figure 4 As shown, the outer side of the hollow rib plate 15 is fixedly mounted on the opposite sides of the fixed tube 2, the inner dividing disk 12, the support tube 13 and the reinforcing rib plate 14, and a plurality of holes are opened on the inner side of the hollow rib plate 15. The reinforcing rib plate 14 is fixedly mounted on the inner side of the inner dividing disk 12.

[0024] The hollow rib plate 15 can increase the stress on the inner structure of the inner dividing plate 12 while connecting the air, reduce the possibility of dislocation and deformation, and increase the stress on the overall structure inside the inner dividing plate 12, so that the inner side can be deformed while maximizing the stress and load, making the internal structure stable and having good use effect.

[0025] In another embodiment, Figure 3 and Figure 4 As shown, the permanent magnets 11 are evenly distributed on the inner side of the suction cup shell 1 in a linear array with N poles and S poles staggered, and the hole grooves 17 are connected to the magnet installation grooves 16.

[0026] By setting the permanent magnet 11 and the hole groove 17, the cross arrangement of the N and S poles of the permanent magnet 11 makes the magnetic attraction stable, facilitates the auxiliary magnetic grasping, and increases the stability of the structure. The setting of the hole groove 17 can form a vacuum cavity inside the permanent magnet 11 through glue when installing, and contain a certain amount of glue to ensure the stable installation of the permanent magnet 11.

[0027] In another embodiment, Figure 1-Figure 4 As shown, the two fixed tubes 2 pass through the hollow rib plate 15 and the suction cup shell 1 and extend to the top of the suction cup shell 1. The top of the protrusion 6 is fixedly fitted with the bottom of the fixed tube 2. The two fixed tubes 2 and the supporting tube 13 are symmetrically and evenly distributed on the inner side of the inner dividing plate 12 in a rectangular shape.

[0028] By setting the hollow ribs 15 and the guide holes 18, after the suction cup shell 1 is lifted by the fixing tube 2 and the metal ring 3, the guide holes 18 and the hollow ribs 15 cause the structure on the inner side of the inner dividing plate 12 to deform so that the airflow can be discharged, and the bottom of the soft chassis 5 is vacuumed by the deformation and retraction of the protrusions 6 to increase the adsorption force. This setting increases the force strength and allows the structure to cope with the operation scenarios of lifting and exhausting air, thereby increasing the overall adaptability and adapting to different operation equipment.

[0029] In another embodiment, Figure 1-Figure 4 As shown, the suction cup shell 1, the fixing tube 2, the supporting column 9, the reinforcing column 10, the inner dividing plate 12, the supporting tube 13, the reinforcing rib plate 14 and the hollow rib plate 15 are all made of hard polymer materials, the reinforcing column 10 is made of hard polymer materials, and the soft chassis 5 and the protrusion 6 are made of thinner soft polymer materials.

[0030] The material of the soft chassis 5 and the protrusion 6 is convenient for being recessed when deformed on the inner side of the inner dividing plate 12, so as to form a vacuum chamber and increase the stability of extraction. The provision of the reinforcement column 10 increases the force strength of the outer side, so that the outer side is structural support with magnetic attraction, and the inner side is vacuum extraction, which increases the force under structural stability. The polymer material described in the scheme is a polymer material produced by blending different proportions according to different usage requirements, such as silicone and rubber, as well as soft and hard polymer materials, and compound polymer materials whose elasticity, toughness and oil resistance cannot be met by a single material.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
