Description

Technical Field

[0001] This utility model relates to the field of vacuum suction cup technology, specifically a vacuum suction cup with strong adsorption force. Background Technology

[0002] A strong suction vacuum cup is a device that uses the principle of vacuum to generate a strong suction force. It creates a local vacuum environment by expelling the air between the suction cup and the object's contact surface, allowing atmospheric pressure to press the suction cup tightly against the object's surface, thus achieving a firm adhesion. It is commonly used for handling, fixing, or lifting smooth and flat objects such as glass, tiles, and metal plates. It features simple operation, no damage, and strong load-bearing capacity, and is widely used in industries such as manufacturing, construction, and logistics.

[0003] Authorization announcement number CN221894112U discloses a vacuum suction cup for preventing workpiece adhesion deformation. The technical solution is as follows: "It includes a suction cup cover and a housing. An air pipe is fixedly connected to the upper surface of the housing, and a suction cup cover is fixedly connected to the lower surface of the housing. A sealing ring is fixedly snapped onto the lower surface of the suction cup cover, and several fixing nuts are uniformly welded to the upper surface of the suction cup cover." The beneficial effect is that by evacuating the air from inside the suction cup cover through the air pipe, the inside of the suction cup cover is in a negative pressure state. The workpiece is adhered and fixed by the suction cup cover, and the area where the workpiece is adhered is supported by several rubber blocks and fixing screws, thus preventing workpiece deformation.

[0004] The above technical solution has the following drawbacks. First, there are multiple fixing screws, and each rubber block needs to be adjusted by rotating its corresponding fixing screw, which makes the adjustment of the rubber blocks more troublesome. Moreover, since the fixing screws do not rotate synchronously, there will be slight differences in the height of the rubber blocks, which makes it impossible for the workpiece to fully adhere to all the rubber blocks, thus affecting the adsorption of the workpiece. Therefore, a vacuum suction cup with strong adsorption force is proposed to solve the problems mentioned above. Utility Model Content

It solves the problem that when adjusting the rubber block with the existing vacuum suction cup, it is necessary to rotate the corresponding fixing screw, which not only makes the adjustment of the rubber block more troublesome, but also causes certain differences in the height of the rubber block fitting.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A vacuum suction cup with strong adsorption force includes an upper suction cup cover, a lower suction cup cover, and a rubber support base. The outer walls of the upper and lower suction cup covers are provided with an adjustment structure for the height of the rubber support base.

[0008] The adjustment structure includes a mounting plate fixedly installed on the outer peripheral wall of the upper suction cup cover. An adjusting threaded rod is threadedly connected to the inside of the mounting plate. An adjusting seat is threadedly connected to the outer peripheral wall of the adjusting threaded rod.

[0009] Furthermore, the stretching assembly includes two fixed rods fixedly installed on the inner peripheral wall of the upper suction cup cover, a fixed seat fixedly installed between the two fixed rods, a tension spring fixedly installed at the bottom of the fixed seat, and a column fixedly installed at the bottom end of the tension spring.

[0010] Furthermore, a friction sleeve is fixedly installed at the bottom of the fixed base, the tension spring is slidably connected to the inner peripheral wall of the friction sleeve, and the column is slidably connected to the inner peripheral wall of the friction sleeve.

[0011] Furthermore, the connecting rod is fixedly installed at the bottom end of the column, and the connecting rod is located between the upper suction cup cover and the lower suction cup cover.

[0012] Furthermore, both the mounting plate and the adjusting seat have threaded holes inside, and the adjusting threaded rod is threadedly connected inside the two threaded holes.

[0013] Furthermore, there are five rubber support seats, which are fixedly installed at the bottom of five support rods and are arranged in a ring inside the lower suction cup cover.

[0014] Furthermore, a rubber ring is fixedly installed at the bottom of the lower suction cup cover, and a negative pressure suction pipe is fixedly installed at the top of the upper suction cup cover.

[0015] Furthermore, two connecting plates, which are arc-shaped, are fixedly installed between the upper suction cup cover and the lower suction cup cover.

[0016] Furthermore, the sealing rings are slidably connected to the outer peripheral walls of the upper and lower suction cup covers, and the sealing rings are slidably connected to the two connecting plates.

[0018] Compared with the prior art, this utility model provides a vacuum suction cup with strong adsorption force, which has the following characteristics:

[0019] Beneficial effects:

[0020] 1. This strong suction vacuum suction cup moves the sealing ring downwards by adjusting the threaded rod, adjusting seat, mounting rod, and mounting seat. The push rod and pressure plate drive the connecting rod and circular mounting plate to move downwards synchronously, so that the five rubber support seats move downwards to the same height. This allows the workpiece to fit against the bottom of the five rubber support seats. Moreover, the effect of adjusting the five rubber support seats can be achieved by simply rotating the adjusting threaded rod, which improves the convenience of use.

[0021] 2. This strong suction vacuum suction cup uses the action of a fixed base, a tension spring, and a column to limit the installation of the connecting rod, allowing the connecting rod to move vertically and horizontally. In addition, the tension spring will pull the five rubber support bases upward. When the rubber support bases are not in use, they will move into the interior of the lower suction cup cover.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1 to 3 The strong suction vacuum suction cup in this embodiment includes an upper suction cup cover 1, a lower suction cup cover 2, and a rubber support base 21. The outer walls of the upper suction cup cover 1 and the lower suction cup cover 2 are provided with an adjustment structure for the height of the rubber support base 21.

[0028] A rubber ring 3 is fixedly installed at the bottom of the lower suction cup cover 2, and a negative pressure suction pipe 25 is fixedly installed at the top of the upper suction cup cover 1. Two connecting plates 12 are fixedly installed between the upper suction cup cover 1 and the lower suction cup cover 2. The connecting plates 12 are arc-shaped.

[0029] In this embodiment, the adjustment structure includes a mounting plate 4 fixedly installed on the outer peripheral wall of the upper suction cup cover 1. An adjustment threaded rod 5 is threadedly connected inside the mounting plate 4. Threaded holes are opened inside both the mounting plate 4 and the adjustment seat 6. The adjustment threaded rod 5 is threadedly connected inside the two threaded holes.

[0030] In this embodiment, the outer peripheral wall of the adjusting threaded rod 5 is threadedly connected to an adjusting seat 6. Side plates 7 are fixedly installed on both the front and rear sides of the adjusting seat 6. An mounting rod 8 is fixedly installed on the right side of the side plate 7. An mounting seat 9 is fixedly installed on the side of the mounting rod 8 away from the side plate 7. An mounting ring 10 is fixedly installed on the right side of the mounting seat 9. A sealing ring 11 is fixedly installed on the inner peripheral wall of the mounting ring 10. The sealing ring 11 is slidably connected to the outer peripheral walls of the upper suction cup cover 1 and the lower suction cup cover 2. The sealing ring 11 is slidably connected to the two connecting plates 12.

[0031] It should be noted that the sealing ring 11 seals the gap between the upper suction cup cover 1 and the lower suction cup cover 2, preventing gas leakage.

[0032] In this embodiment, two push rods 22 are fixedly installed on the inner peripheral wall of the sealing ring 11. A pressure plate 23 is movably installed on the outer wall of the push rod 22. A positioning groove is opened inside the pressure plate 23. The push rod 22 is slidably connected inside the positioning groove. The size of the push rod 22 is adapted to the positioning groove. A connecting rod 17 is fixedly installed on one side of the two pressure plates 23. A circular mounting plate 18 is fixedly installed at the bottom of the connecting rod 17. Four side rods 19 are fixedly installed on the outer peripheral wall of the circular mounting plate 18. Support rods 20 are fixedly installed at the bottom of both the side rods 19 and the bottom of the circular mounting plate 18. There are five rubber support seats 21. The five rubber support seats 21 are respectively fixedly installed at the bottom of the five support rods 20. The five rubber support seats 21 are distributed in a ring inside the lower suction cup cover 2.

[0033] It should be noted that the push rod 22 drives the pressure plate 23 to descend synchronously, thereby driving the five rubber support seats 21 to descend synchronously and be at the same horizontal height.

[0034] In this embodiment, the interior of the upper suction cup cover 1 is provided with a stretching assembly for stretching the rubber support seat 21. The stretching assembly includes two fixed rods 13 fixedly installed on the inner peripheral wall of the upper suction cup cover 1. A fixed seat 14 is fixedly installed between the two fixed rods 13. A tension spring 15 is fixedly installed at the bottom of the fixed seat 14. A column 16 is fixedly installed at the bottom end of the tension spring 15.

[0035] It should be noted that when the rubber support 21 is not in use, the tension spring 15 and the column 16 will pull the rubber support 21 upward, causing the rubber support 21 to move into the interior of the lower suction cup cover 2, thereby improving the protective effect on the rubber support 21.

[0036] In this embodiment, a friction sleeve 24 is fixedly installed at the bottom of the fixed base 14, a tension spring 15 is slidably connected to the inner peripheral wall of the friction sleeve 24, a column 16 is slidably connected to the inner peripheral wall of the friction sleeve 24, and a connecting rod 17 is fixedly installed at the bottom end of the column 16. The connecting rod 17 is located between the upper suction cup cover 1 and the lower suction cup cover 2.

[0037] It should be noted that the friction sleeve 24 improves the stability of the tension spring 15.

[0038] It should be noted that the five rubber support seats 21 are evenly distributed in a ring, which improves the uniformity of the force points when adsorbing the workpiece, thereby preventing damage to the workpiece.

[0039] It should be noted that the negative pressure suction pipe 25 is connected to an external negative pressure air pump.

[0040] The working principle of the above embodiments is as follows:

[0041] When it is necessary to adsorb the workpiece, rotating the adjusting screw 5 will cause the adjusting seat 6 to move downward. At this time, the side plate 7, the mounting rod 8 and the mounting seat 9 will simultaneously drive the mounting ring 10 and the sealing ring 11 to move downward. At the same time, the push rod 22 will move downward in sync with the sealing ring 11. When the push rod 22 slides into the inside of the pressure plate 23, the push rod 22 will press the pressure plate 23 downward. At this time, the rubber support seat 21 will also move downward. When the bottom of the rubber support seat 21 is at the same height as the bottom of the rubber ring 3, the workpiece can be placed at the bottom of the lower suction cup cover 2. The workpiece will be adsorbed by the negative pressure gas of the negative pressure suction pipe 25.

[0042] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
