Description

Technical Field

[0001] This application relates to the field of vacuum lifting equipment technology, and more specifically, to a vacuum lifting equipment. Background Technology

[0002] Vacuum lifters are generally made of flexible materials that possess both rigidity and flexibility, such as silicone rubber, PVC, polyurethane, nitrile rubber, or vinyl-containing polymers. Most vacuum lifters have a hollow cone-shaped structure, with the wall facing the object being lifted being concave upwards in the center. To use them, the vacuum lifter is placed against the object's surface, and the center of the lifter is pressed against the surface to expel air from the cone. Releasing the pressure creates negative pressure within the cone as the lifter resets, allowing it to adhere to the object's surface. Alternatively, the lifter can be placed against the object's surface and the air in the cavity between the lifter and the object's surface can be removed, creating negative pressure within the lifter and thus ensuring a tight grip on the object's surface.

[0003] Traditional vacuum lifters typically achieve the vacuum effect manually or electrically. Electric vacuum lifters are complex in structure, expensive, and have high maintenance costs. Manual vacuum lifters, while cheaper, often offer a poor user experience, requiring users to control the vacuum structure for extended periods, or accidentally touching the vacuum structure during use can lead to loss of adsorption.

[0004] Therefore, this application proposes a vacuum lifting device to solve the aforementioned problems. Utility Model Content

[0005] To address the aforementioned problems, this application provides a vacuum lifting device.

[0006] The vacuum lifting device provided in this application adopts the following technical solution:

[0007] A vacuum lifting device includes: a housing with an open-bottom cavity; a vacuum handle slidably mounted vertically on the housing, and a gripping handle covering the vacuum handle; the vacuum handle being located above the housing, with a suction cup connected to its bottom, the suction cup being located at the bottom of the housing, and the bottom diameter of the suction cup being larger than the diameter of the housing; a locking element being located at the top of the suction cup within the cavity, and a hook being extending through the top of the housing to engage with the locking element; the locking element including a groove and a slot, and the hook head of the hook matching the slot.

[0008] Furthermore, the slide groove and the slot are connected and combined to form an inverted "7" shape, and the hook head is slidably disposed in the slide groove in a non-vacuum state.

[0009] The above technical solution facilitates smoother operation of the hook in the slide groove when the vacuum handle is pulled up or pressed down, making the cooperation between the various components of the entire vacuum lifting device more precise and smooth during use.

[0010] Furthermore, the card pieces are arranged symmetrically, and the card slots on adjacent card pieces face opposite directions.

[0011] Through the above technical solution, in the actual use of vacuum lifting equipment, especially when lifting heavy objects or in a complex motion state, this combination of double clamps and reverse clamping slots can play a key role in double insurance.

[0012] When subjected to gravity or unexpected bumps or shaking, even if the hook in one direction bears a large external force, the other hook can still be firmly locked in the slot because the slot is facing the opposite direction. This effectively avoids adsorption failure or lifting accidents caused by the hook falling off, providing reliable stability and safety for the entire lifting operation process and greatly reducing potential risks.

[0013] Furthermore, the top of the suction cup is provided with a cross-shaped reinforcing member, the vacuum handle is fixedly connected to the center point of the reinforcing member, and the clip is provided at the longitudinal or vertical end of the reinforcing member.

[0014] Through the above technical solution, the cross-shaped structure greatly enhances the overall structural strength of the suction cup, making it less prone to deformation or damage when subjected to greater suction force and external pressure, significantly extending the service life of the suction cup and reducing the maintenance cost of frequent component replacement due to suction cup damage.

[0015] This reinforcement provides an ideal fixed connection point for the vacuum handle, ensuring a stable and reliable connection between the vacuum handle and the suction cup, and making the force transmission more uniform and efficient.

[0016] The clamps are located at the longitudinal or vertical ends of the reinforcing members, making full use of the structural characteristics of the reinforcing members. This makes the spatial layout of each component more reasonable and compact, further optimizing the force transmission path and enhancing the integrity and coherence of the entire vacuum lifting device structure. This results in a more balanced distribution of force during lifting, effectively improving the stability and accuracy of lifting.

[0017] Furthermore, the hook is located outside the range of the vacuum handle.

[0018] With the aforementioned technical solutions, in actual operation, users frequently interact with the vacuum handle. If the latch is located within the operating area of ​​the vacuum handle, it is easy to accidentally activate it, thereby disrupting the precise engagement between the latch and the locking mechanism, leading to failure of the vacuum lifting device's adsorption function or potential safety hazards. The current design effectively avoids this problem, ensuring the reliability and stability of the engagement structure during lifting. Users do not need to worry about accidents caused by misoperation, allowing them to focus more intently and efficiently complete lifting tasks, greatly improving the safety and convenience of using the vacuum lifting device.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] The rational layout and design of key components such as clamps and reinforcing parts not only optimizes the force transmission path, but also ensures that the force can be evenly and stably distributed throughout the structure during hoisting, reducing the phenomenon of local stress concentration, effectively avoiding component damage or deformation caused by uneven structural stress, and greatly improving the structural strength and durability of vacuum lifting equipment.

[0021] The dual-clamp mechanism, the reasonable arrangement of the hook positions, and the suction cup reinforcement all effectively reduce the risk of safety accidents caused by various unexpected factors during hoisting. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1 -3 provides further detailed description of this application.

[0030] This application discloses a vacuum lifting device, including:

[0031] Housing 1, housing 1 has an open structure with a cavity at the bottom;

[0032] A vacuum handle 2 is vertically slidably mounted on the housing 1, and a grip handle 3 covering the vacuum handle 2 is mounted on the housing 1.

[0033] The vacuum handle 2 is located above the housing 1. The bottom of the vacuum handle 2 is connected to a suction cup 4, which is located at the bottom of the housing 1. The bottom diameter of the suction cup 4 is larger than the diameter of the housing 1.

[0034] The top of the suction cup 4 is provided with a locking piece 5 inside the cavity, and the top of the housing 1 is provided with a hook 6 that engages with the locking piece 5.

[0035] The clip 5 includes a slide 7 and a slot 8, and the hook head 9 of the hook 6 matches the slot 8.

[0036] See Figure 1 , Figure 2 and Figure 3 The slide groove 7 and the slot 8 are connected and the two are combined into an inverted "7" shape. In the non-vacuum state, the hook head 9 is slidably set in the slide groove 7; this makes it easier for the hook head 9 to cooperate more smoothly in the slide groove 7 when the vacuum handle 2 is pulled up or pressed down, so that the cooperation between the various parts of the entire vacuum lifting device is more precise and smooth when in use.

[0037] See Figure 1 , Figure 2 and Figure 3 The clamps 5 are symmetrically arranged, and the slots 8 on adjacent clamps 5 face opposite directions. In the actual use of vacuum lifting equipment, especially when lifting heavy objects or in a complex motion state, this combination of double clamps 5 and reverse slots 8 can play a key role in double protection.

[0038] When subjected to gravity or due to unexpected bumps or shaking, even if the hook 9 in one direction is subjected to a large external force, the other hook 9 can still be firmly engaged in the slot 8 because the slot 8 is facing the opposite direction. This effectively avoids adsorption failure or lifting accidents caused by the hook 9 falling off, providing reliable stability and safety for the entire lifting operation process and greatly reducing potential risks.

[0039] See Figure 1 , Figure 2 and Figure 3 The suction cup 4 is provided with a cross-shaped reinforcing member 10 at the top. The vacuum handle 2 is fixedly connected to the center point of the reinforcing member 10. The clamp 5 is provided at the longitudinal or vertical end of the reinforcing member 10. The cross-shaped structure greatly enhances the overall structural strength of the suction cup 4, making it less prone to deformation or damage when subjected to large suction force and external pressure. This significantly extends the service life of the suction cup 4 and reduces the maintenance cost of frequently replacing parts due to damage to the suction cup 4.

[0040] The reinforcing member 10 provides an ideal fixed connection point for the vacuum handle 2, ensuring a stable and reliable connection between the vacuum handle 2 and the suction cup 4, and making the force transmission more uniform and efficient.

[0041] The clamp 5 is set at the longitudinal or vertical end of the reinforcing member 10, making full use of the structural characteristics of the reinforcing member 10, making the spatial layout of each component more reasonable and compact, further optimizing the force transmission path, enhancing the integrity and coherence of the entire vacuum lifting device structure, making the force distribution more balanced during the lifting process, and effectively improving the stability and accuracy of the lifting.

[0042] See Figure 1 , Figure 2 and Figure 3The hook 6 is located outside the range of the vacuum handle 2. In actual operation, users frequently interact with the vacuum handle 2. If the hook 6 is located within the operating area of ​​the vacuum handle 2, it is easy to accidentally touch it, thereby disrupting the precise engagement between the hook 6 and the locking piece 5, causing the vacuum lifting device's adsorption function to fail or creating safety hazards. The current design effectively avoids this problem, ensuring the reliability and stability of the engagement structure during lifting. Users do not need to worry about accidents caused by misoperation, and can complete lifting tasks more focused and efficiently, greatly improving the safety and convenience of using the vacuum lifting device.

[0043] The implementation principle of a vacuum lifting device according to an embodiment of this application is as follows:

[0044] Before use, place the suction cup 4 against the surface of the object to be absorbed, ensuring that the two are tightly fitted together to form a relatively enclosed space.

[0045] Then, the palm is pressed against the handle 3, and the fingers hook onto the vacuum handle 2 and pull upwards to create a vacuum between the suction cup 4 and the surface of the object to be absorbed. As the air is gradually squeezed out or extracted, the air pressure inside the cavity drops rapidly, creating a negative pressure environment. Under the strong action of the external atmospheric pressure, the suction cup 4 adheres tightly to the surface of the object, thus achieving the initial grasping of the object.

[0046] After the adsorption operation is completed, as negative pressure is formed inside the suction cup 4, the vacuum handle 2 moves upward under the action of force, and the hook head 9 of the hook 6 slides into the slot 8, realizing the locking and ensuring that the tight adsorption state between the suction cup 4 and the surface of the adsorbed object is maintained stably.

[0047] When it is necessary to release the adsorption, the user moves the locking piece 5 in the opposite direction to disengage the hook 6 from the locking piece 5 and break the locking state, so that the vacuum handle 2 can slide on the housing 1, and thus the vacuum lifter can be easily removed from the surface of the adsorbed object.

[0048] Throughout the process, the handle 3 allows the user to hold and operate the vacuum lifting device stably. All components work closely together to complete the lifting task, demonstrating the ingenuity of the mechanical structure design and making full use of the powerful effect of air pressure, thus achieving efficient and safe vacuum lifting function.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
