Description

Technical Field

[0001] The present invention relates to the technical field of passive vacuum suction cups, and in particular to an adjustable vacuum suction cup device. Background Art

[0002] In fields such as industrial automation, logistics handling, and construction, various lifting and fixing equipment are often needed to move or support heavy objects. Traditional lifting methods usually rely on mechanical methods such as hooks and wire ropes. Although these methods are simple and effective, they have limitations in certain specific situations. For example, when operating on objects with fragile or smooth surfaces (such as lifting large glass curtain walls and hanging precision instruments and equipment), the objects may be damaged due to excessive or uneven contact force. In addition, in some applications that require rapid loading and unloading or frequent position adjustments, traditional methods are not flexible and efficient enough. To solve the above problems, vacuum suction cup technology has emerged and has been widely used. Vacuum suction cups use the suction force generated by atmospheric pressure differences to lift objects, with advantages such as no damage to the lifting surface and simple operation. However, most existing vacuum suction cup devices have fixed structures, making it difficult to adjust the suction force according to actual needs or adapt to objects of different shapes and weights. When releasing the object, external force is often required to break the vacuum state, which is inconvenient to operate and inefficient. Summary of the Invention

[0015] a second air channel, one end of which is connected to the other end of the first air channel, and an inner wall of the second air channel is provided with an internal thread;

[0016] One end of the third air channel is connected to the other end of the second air channel, and the other end of the third air channel passes through the connecting column.

[0017] In some embodiments, the inner diameter of the third air channel is larger than the inner diameter of the second air channel.

[0018] In some embodiments, the sealing block comprises:

[0019] The rod body has an external thread on the right side thereof that matches the internal thread of the second air channel;

[0020] A plurality of sealing plugs are provided, and the plurality of sealing plugs are located on the left side of the rod body, the sealing plugs are sleeved on the side wall of the rod body, the sealing plugs are fixedly connected to the rod body, and the outer diameter of the sealing plugs matches the inner diameter of the third airway;

[0021] The rotating head is located at the left end of the rod body and is fixedly connected to the left end of the rod body.

[0022] In some embodiments, the suspension assembly comprises:

[0023] A rotating shaft is located inside the mounting hole, the rotating shaft matches the mounting hole, and the mounting end of the rotating shaft is fixedly connected to the inner wall of the mounting hole;

[0024] A connecting rod is located at the bottom of the rotating shaft, and the top of the connecting rod is fixedly connected to the rotating end of the rotating shaft;

Installation and maintenance are quick and easy, and it can be quickly assembled or disassembled according to actual needs. The rectangular cross-section of the connecting column improves the device's stability and bending resistance, while the graded design of the airway ensures more uniform airflow distribution.

Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. Throughout this application, unless otherwise specified, "plurality" means two or more.

[0041] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0042] See Figure 1-5 As shown, an adjustable vacuum suction cup device according to an embodiment of the present application includes:

[0043] A support plate 1, with fixing holes 2 and mounting holes 3 provided on its top;

[0044] A fixing assembly is provided on the top of the support plate 1, and the top of the fixing assembly is threadedly connected to the fixing hole 2;

[0045] The top of the suspension component is fixedly connected to the inner wall of the mounting hole 3.

[0046] In some specific embodiments, a plurality of fixing holes 2 are provided, each of the fixing holes 2 passes through the support plate 1 , and an inner wall of the fixing hole 2 is provided with an internal thread.

[0047] In some specific embodiments, the mounting hole 3 coincides with the transverse axis of the support plate 1 .

[0048] In some specific embodiments, the fixing assembly includes:

[0049] The connecting column 4 has a rectangular axial cross section and an air passage is provided inside the connecting column 4;

[0050] A suction cup 5 is located at one end of the connecting column 4. The connecting end of the suction cup 5 is fixedly connected to one end of the connecting column 4. One end of the airway is connected to the suction cup 5. The other end of the airway is threaded and sealed with a sealing block 6.

[0051] One end of the connector 7 is fixedly connected to the other end of the connecting column 4 , and an external thread matching the internal thread of the fixing hole 2 is provided around the side wall of the connector 7 , and the connector 7 is threadedly connected to the fixing hole 2 .

[0052] It should be understood that the suction cup 5 is used to be adsorbed onto the target wall panel, wherein the connector 7 can be threadedly connected to different fixing holes 2 to adapt to different environments.

[0053] Multiple fixing holes 2 run through the support plate 1, allowing the connector 7 to be threaded into fixing holes 2 at different locations, allowing for flexible adjustment of the height and angle of the suction cup 5 assembly to accommodate different lifting requirements. By selecting fixing holes 2 at different locations, the center of gravity of the object being lifted can be balanced, improving the stability of the lifting process. The design of multiple fixing holes 2 makes the device suitable for a variety of working environments and meets the lifting requirements in different scenarios. The mounting holes 3 coincide with the transverse axis of the support plate 1, ensuring that the suspension components (such as the rotating shaft 14) are symmetrically positioned on the support plate, ensuring uniform force during lifting and avoiding tilting or shaking caused by eccentricity. The symmetrical design enhances the load-bearing capacity of the support plate 1 and ensures the overall stability of the device when lifting heavy objects. The position of the mounting holes 3 coincides with the axis of the support plate 1, simplifying the installation process of the suspension components and facilitating subsequent maintenance and replacement. The rectangular cross-section structure increases the bending strength of the connecting column 4, making it less likely to deform during lifting and ensuring the stability of the airway. The rectangular cross-section design makes the layout of the airway within the connecting column 4 more compact, improving the overall space utilization of the device.

[0054] The suction cup 5 is fixedly connected to one end of the connecting column 4 to ensure that the suction cup 5 will not fall off or shift during the lifting process, thereby ensuring the stability of the adsorption force. One end of the airway is connected to the suction cup 5, which is convenient for adjusting the vacuum degree inside the suction cup 5 through the airway to achieve flexible control of the adsorption force. The sealing block 6 is sealed and connected to the airway through a thread, which is convenient for disassembly and replacement, and is convenient for maintenance and cleaning. By rotating the sealing block 6, the on and off of the airway can be easily adjusted to achieve the automatic disengagement function of the suction cup 5 without the need for external force to destroy the vacuum state. The external thread on the side wall of the connector 7 matches the internal thread of the fixing hole 2 to achieve quick threaded connection, simplifying the installation process of the device. The connector 7 can be threadedly connected to the fixing holes 2 in different positions to meet the requirements of different lifting heights and angles, thereby improving the flexibility of the device.

[0055] Each component of the fixed assembly (connecting column 4, suction cup 5, sealing block 6, connector 7) adopts a modular design, which is easy to assemble, disassemble and maintain. Through threaded connection and rotating sealing block 6, the operation of the device is simpler and more efficient, reducing labor intensity.

[0056] In some embodiments, the airway comprises:

[0057] a first air passage 8, one end of which is in communication with the suction cup 5;

[0058] a second air channel 9, one end of which is connected to the other end of the first air channel 8, and an inner wall of the second air channel 9 is provided with an internal thread;

[0059] One end of the third air channel 10 is connected to the other end of the second air channel 9 , and the other end of the third air channel 10 passes through the connecting column 4 .

[0060] In some specific embodiments, the inner diameter of the third air channel 10 is greater than the inner diameter of the second air channel 9 .

[0061] In some specific embodiments, the sealing block 6 includes:

[0062] The rod body 11 has an external thread on its right side that matches the internal thread of the second air channel 9;

[0063] A plurality of sealing plugs 12 are provided, and the plurality of sealing plugs 12 are located on the left side of the rod body 11. The sealing plugs 12 are sleeved on the side wall of the rod body 11 and are fixedly connected to the rod body 11. The outer diameter of the sealing plugs 12 matches the inner diameter of the third airway 10;

[0064] The rotating head 13 is located at the left end of the rod body 11 , and the rotating head 13 is fixedly connected to the left end of the rod body 11 .

[0065] It should be understood that when the suction cup 5 is in the adsorption state, the sealing block 6 is sealed and threadedly connected to the third air channel 10 and the second air channel 9. When adsorption is not required, the entire rod body is rotated by rotating the head 13 to disengage the sealing block 6 from the third air channel 10 and the second air channel 9, allowing the gas to enter the suction cup 5, thereby achieving automatic disengagement without applying external force.

[0066] One end of the first air channel 8 is directly connected to the suction cup 5 and is the channel for gas to enter and exit the suction cup. Its interior is a smooth airflow channel, ensuring that the gas can flow smoothly from the suction cup into the airway system. As the starting point of the airway system, the first air channel 8 ensures that the gas inside the suction cup 5 can quickly enter the subsequent airway, providing a basis for adsorption or detachment. Through the guidance of the first air channel 8, the gas can be evenly distributed, avoiding unstable adsorption force caused by uneven airflow.

[0067] One end of the second air channel 9 is connected to the first air channel 8, and the other end is connected to the third air channel 10. The inner wall is provided with an internal thread for threaded connection with the rod body 11 of the sealing block 6. The inner diameter of the second air channel 9 is relatively small, which facilitates sealing by threading. The internal thread design enables the second air channel 9 to fit tightly with the rod body 11 of the sealing block 6 to form a reliable seal to prevent gas leakage. The threaded connection allows the sealing block 6 to be easily disassembled or installed, which is convenient for maintenance and adjustment. The inner diameter of the second air channel 9 is relatively small, which can limit the gas flow and facilitate precise control of the adsorption force.

[0068] One end of the third air channel 10 is connected to the second air channel 9, and the other end passes through the connecting column 4, directly communicating with the external environment. Its inner diameter is larger than that of the second air channel 9, facilitating rapid gas flow. This larger inner diameter allows gas to quickly exit or enter the suction cup 5, enabling rapid switching between suction and detachment.

[0069] The right side of the rod body 11 is provided with an external thread that matches the internal thread of the second air passage 9 and is used to seal the air passage. The interior of the rod body 11 is a hollow structure, which facilitates the passage of gas. The combination of the external and internal threads ensures a tight connection between the rod body 11 and the second air passage 9, forming a reliable seal and preventing gas leakage. The threaded design of the rod body 11 allows the sealing block 6 to be easily removed or installed by rotation, which is convenient to operate. The design of the rod body 11 is simple and sturdy, and can withstand a certain amount of torque to ensure the stability of the seal.

[0070] Multiple sealing plugs 12 are sleeved on the side wall of the rod body 11 and are located on the left side of the rod body 11. The outer diameter of the sealing plugs 12 matches the inner diameter of the third air channel 10 and is used to seal the third air channel 10. The sealing plugs 12 are fixedly connected to the rod body 11 and are usually made of rubber or elastic material to ensure a good sealing effect. The design of multiple sealing plugs 12 enhances the sealing effect, and even if some of the sealing plugs are worn, the sealing of the air channel can still be maintained. The outer diameter of the sealing plugs 12 matches the inner diameter of the third air channel 10, ensuring the tightness of the seal and preventing gas leakage. The rotating head 13 is located at the left end of the rod body 11 and is usually hexagonal or circular in design, which is easy to rotate manually. The rotating head 13 is fixedly connected to the rod body 11, and by rotating the rotating head 13, the entire sealing block 6 can be driven to rotate. The design of the rotating head 13 makes operation more convenient, and the sealing block 6 can be easily rotated without the aid of tools, reducing labor intensity. By rotating the rotating head 13, the suction cup can be quickly attached or detached, which is simple and efficient to operate.

[0071] The rod 11 of the sealing block 6 is connected to the second air channel 9 through a thread, and the sealing plug 12 is in close contact with the third air channel 10, blocking the gas from entering the suction cup 5. A vacuum is formed inside the suction cup 5, generating an adsorption force, and the lifted object is firmly adsorbed.

[0072] In some specific embodiments, the suspension assembly includes:

[0073] The rotating shaft 14 is located inside the mounting hole 3, and the rotating shaft 14 matches the mounting hole 3, and the mounting end of the rotating shaft 14 is fixedly connected to the inner wall of the mounting hole 3;

[0074] A connecting rod 15 is located at the bottom of the rotating shaft 14, and the top of the connecting rod 15 is fixedly connected to the rotating end of the rotating shaft 14;

[0075] The suspension ring 16 is located at the bottom of the connecting rod 15 , and the top of the suspension ring 16 is fixedly connected to the bottom of the connecting rod 15 .

[0076] In some specific embodiments, a plurality of suspension holes 17 are provided on the suspension ring 16 .

[0077] In some specific embodiments, the axial cross-section of the suspension hole 17 is a rectangular structure.

[0078] It should be understood that the hanging hole 17 and the hanging ring 16 are used to hang different objects, and the hanging ring 16 is rotatable.

[0079] Rotating shaft 14 is located within mounting hole 3, matching the mounting hole 3. Its mounting end is fixedly connected to the inner wall of mounting hole 3. The rotating end of rotating shaft 14 is fixedly connected to the top of connecting rod 15, allowing connecting rod 15 to rotate about the axis of rotating shaft 14. The design of rotating shaft 14 allows connecting rod 15 to rotate freely, adapting to the swing or tilt of the object during lifting, and avoiding stress concentration or damage caused by a rigid connection. The fixed connection between rotating shaft 14 and mounting hole 3 ensures the stability of the suspension assembly, preventing displacement or dislodging during lifting.

[0080] The connecting rod 15 is located at the bottom of the rotating shaft 14, with its top fixedly connected to the rotating end of the rotating shaft 14, and its bottom fixedly connected to the top of the suspension ring 16. The connecting rod 15 usually adopts a rigid structure (such as a cylindrical or rectangular cross-section) to transfer the weight and torque of the hoisted object. The rigid structure of the connecting rod 15 can efficiently transfer the weight of the hoisted object to the rotating shaft 14 and the support plate 1, avoiding energy loss due to deformation. The design of the connecting rod 15 (such as a rectangular cross-section) enhances its bending resistance and prevents bending or breaking due to lateral force during the lifting process.

[0081] The suspension ring 16 is located at the bottom of the connecting rod 15, and its top is fixedly connected to the bottom of the connecting rod 15. The suspension ring 16 usually adopts a ring design and is used to connect with the hoisted object. A plurality of suspension holes 17 are provided on the suspension ring 16 for passing a sling or a hook. The design of the multiple suspension holes 17 allows the sling or the hook to be passed from different directions, realizing multi-point connection and improving the stability and safety of the lifting. The rectangular cross-section design of the suspension hole 17 enables the sling or the hook to be firmly fixed to the suspension ring 16, avoiding loose connection due to sliding or rotation. The multiple suspension holes 17 can evenly distribute the weight of the hoisted object to all directions of the suspension ring 16, avoiding damage caused by excessive force on a single point.
