Description

Technical Field

[0001] This application relates to the field of gripping tools, and in particular, to a portable gripping device. Background Technology

[0002] The information provided in this section is for the purpose of generally presenting the background of this application. To the extent described in this section, the work of the currently named inventors and aspects of the description that may not constitute prior art at the time of filing are neither explicitly nor implicitly considered to be prior art of this application.

[0003] Vacuum suction cups can grasp various items for convenient movement and transport. Existing vacuum suction cup lifting devices come in many forms. For example, Chinese Patent Publication No. CN111943013A discloses a wireless vacuum suction cup lifting device, which includes a lifting device shell, a lifting suction cup, a vacuuming device, and a power supply. The vacuuming device is used to evacuate air from inside the lifting suction cup. Its key feature is that the lifting device shell has an installation port, and the power supply includes a battery box containing a rechargeable battery. The battery box is snapped into the installation port, and the battery inside the battery box is electrically connected to the vacuuming device. Because the battery box and the lifting device shell are detachable, traditional shutdown charging operations are eliminated, improving efficiency.

[0004] However, the existing vacuum suction cup devices have a relatively complex structure. Because they need to drive multiple suction cups, the overall size and weight are relatively large, which is not conducive to users holding them with one hand to grasp items such as plates, glass, and cups, while using the other hand to perform fine operations such as cleaning, rinsing, and polishing. Therefore, they are not portable enough. Utility Model Content

[0005] In view of at least one of the above technical problems, this application provides a portable gripping device that can be connected to a suction cup assembly on the outside of the mounting base by setting a vacuum mechanism inside the mounting base, and a handle is set on the side wall of the mounting base for easy one-handed gripping by the user. The overall structure is more streamlined, portable and easy to use.

[0006] According to one aspect of this application, a portable gripping device is provided, including a mounting base, a handle, and a suction cup assembly:

[0007] The suction cup assembly is connected to the front end of the mounting base. The mounting base is equipped with a vacuum mechanism, which is connected to the suction cup assembly. The vacuum mechanism is used to extract the air from the inner cavity of the suction cup assembly to form a negative pressure when the suction cup assembly comes into contact with the object to be grasped, so that the suction cup assembly can stick to the object to be grasped.

[0008] The handle is connected to the side wall of the mounting base. The handle contains a power module that is connected to the vacuum mechanism. The side wall of the handle is equipped with a control switch for controlling the vacuum mechanism.

[0009] In some embodiments of this application, the inner cavity of the handle is provided with a battery compartment for installing a power module, and the side wall of the handle is provided with a battery compartment cover for covering the battery compartment. The portable gripping device also includes a sealing sleeve for being fitted onto the handle and for covering and sealing the battery compartment.

[0010] In some embodiments of this application, the portable gripping device further includes a connecting tube, a motor, a motor switch, and a first sealed bearing. The connecting tube is the main shaft of the motor, the motor is disposed in the mounting base, the first end of the connecting tube is connected to the vacuum mechanism through the first sealed bearing, the second end of the connecting tube is detachably connected to the suction cup connector, and the motor switch is disposed on the handle and is used to control the start and stop of the motor.

[0011] In some embodiments of this application, a limiting hole is provided on the outer wall of the sealing sleeve, which is used to avoid the control switch.

[0012] In some embodiments of this application, the suction cup assembly includes a suction cup body and a suction cup connector, the suction cup connector being disposed on the suction cup body. The portable gripping device also includes a connecting tube, the first end of which is connected to a vacuum mechanism, and the second end of which is detachably connected to the suction cup connector.

[0013] In some embodiments of this application, the connecting pipe is a telescopic pipe structure.

[0014] In some embodiments of this application, the suction cup assembly further includes a suction cup base plate, which is detachably connected to the suction cup body. The suction cup base plate and the suction cup body enclose a negative pressure inner cavity, and an air extraction hole is provided on the suction cup base plate.

[0015] In some embodiments of this application, the outer wall of the suction cup base plate is provided with multiple anti-slip protrusions at intervals, and the anti-slip protrusions are arranged to avoid the air extraction holes.

[0016] In some embodiments of this application, a lifting member is provided at the edge of the suction cup body, which is used to lift the suction cup body so that the suction cup assembly is detached from the object to be grasped.

[0017] In some embodiments of this application, a heat dissipation cavity is provided inside the rear end of the mounting base, and heat dissipation fins are provided on the inner wall of the mounting base.

[0018] This application has the following beneficial effects:

[0019] This portable gripping device incorporates a vacuum mechanism within the mounting base. A suction cup assembly is positioned at the front of the mounting base and connected to the vacuum mechanism. The vacuum mechanism creates a vacuum within the suction cup assembly, allowing the suction cup to grip the object. A handle is located on the side wall of the mounting base, and the battery is housed in a battery compartment within the handle. The control switch for the vacuum mechanism is also located on the side wall of the handle, enabling the user to hold the handle with one hand and easily activate the vacuum mechanism by pressing the control switch. Since the suction cup assembly and handle are perpendicular, and the vacuum mechanism is located inside the mounting base, the main weight is concentrated at the mounting base, resulting in improved comfort for one-handed use. This facilitates moving and transporting the object after gripping, or using the other hand for finer operations such as cleaning, rinsing, and polishing, effectively enhancing ease of use.

[0027] The embodiments of this application are described in detail below with reference to the accompanying drawings; however, this application may be implemented in a variety of different ways as defined and covered below.

[0028] Figure 1 This is a schematic diagram of the overall structure of a preferred embodiment of this application; Figure 2 This is a schematic diagram of the suction cup base plate according to a preferred embodiment of this application; Figure 3 This is a schematic diagram of the installation of the suction cup assembly according to a preferred embodiment of this application; Figure 4 This is a schematic diagram of the installation of the motor according to a preferred embodiment of this application.

[0029] A portable gripping device includes a mounting base 1, a handle 2, and a suction cup assembly 3.

[0030] The suction cup assembly 3 is connected to the front end of the mounting base 1. The mounting base 1 is provided with a vacuum mechanism 6, which is connected to the suction cup assembly 3. The vacuum mechanism 6 is used to extract the air in the cavity of the suction cup assembly 3 to form a negative pressure when the suction cup assembly 3 comes into contact with the object to be grasped, so that the suction cup assembly 3 can suck up the object to be grasped.

[0031] The handle 2 is connected to the side wall of the mounting base 1. The handle 2 is equipped with a power module that is connected to the vacuum mechanism 6. The side wall of the handle 2 is equipped with a control switch 5 for controlling the vacuum mechanism 6.

[0032] Here, "vacuuming mechanism 6" refers to a mechanism connected to the suction cup assembly 3 to achieve vacuuming. In some embodiments, the vacuuming mechanism 6 is a vacuum pump or an air pump. Using existing, mature vacuuming devices helps reduce the overall manufacturing cost of the gripping device and facilitates subsequent maintenance and replacement. In some embodiments, the vacuuming mechanism 6 can be connected to the power strip via a power cord without requiring battery power.

[0033] Here, "mounting seat 1" refers to the mechanism that limits the installation of the vacuum pumping mechanism 6. In some embodiments, the mounting seat 1 is a cylindrical structure with an installation cavity inside, which is used to limit the installation of the vacuum pumping mechanism 6.

[0034] This portable gripping device incorporates a vacuum mechanism 6 within the mounting base 1. A suction cup assembly 3 is positioned at the front end of the mounting base 1 and connected to the vacuum mechanism 6. The vacuum mechanism 6 creates a vacuum within the suction cup assembly 3, allowing it to grip the object. A handle 2 is located on the side wall of the mounting base 1, and the battery is housed in a battery compartment within the handle 2. The control switch 5 for the vacuum mechanism 6 is also located on the side wall of the handle 2, enabling the user to hold the handle 2 with one hand and easily activate the vacuum mechanism 6 by pressing the control switch 5. This allows the user to grip the object using the suction cup assembly 3. Because the suction cup assembly 3 and handle 2 are perpendicular, and the vacuum mechanism 6 is located inside the mounting base 1, the main weight is concentrated at the mounting base 1, improving the user's comfort when holding the device with one hand. This facilitates moving and transporting the object after gripping, or using the other hand for cleaning, rinsing, polishing, or other finer operations, effectively enhancing usability.

[0035] Preferably, please refer to Figure 2 , 3 As shown, the inner cavity of the handle 2 is provided with a battery compartment for installing the power module, and the side wall of the handle 2 is provided with a battery compartment cover 21 for covering the battery compartment. The portable gripping device also includes a sealing sleeve 7, which is used to cover the handle 2 and seal the battery compartment.

[0036] Understandably, covering the battery compartment with the battery compartment cover 21 protects the battery inside. To further enhance the sealing and protection of the battery compartment, a sealing sleeve 7 is fitted onto the handle 2 to cover and seal the battery compartment, providing effective sealing protection and waterproofing and dustproofing, which helps to broaden the application scenarios of the gripping device.

[0037] Optionally, the sealing sleeve 7 is made of elastic rubber material, which gives the sealing sleeve 7 a deformable function, allowing it to fit more securely against the outer wall of the handle 2, and making it easier to directly remove and peel the sealing sleeve 7 from the handle 2, thus facilitating the installation and removal of the sealing sleeve 7.

[0038] Specifically, the sealing sleeve 7 is a sleeve structure with an open top. The sealing sleeve 7 can be easily inserted into the handle 2 for installation through the opening at the top of the sealing sleeve 7. When removing the sealing sleeve 7, it can be directly peeled off, achieving efficient disassembly and assembly, which helps to improve the efficiency of battery replacement.

[0039] Preferably, please refer to Figure 1 and 2 As shown, the outer wall of the sealing sleeve 7 is provided with a plurality of limiting grooves 71 spaced apart. The limiting grooves 71 are used to limit the user's fingers holding the handle 2.

[0040] It is understandable that by limiting the user's fingers when the user holds the handle 2 with one hand through the limiting groove 71, the friction between the user and the sealing sleeve 7 can be increased, the anti-slip effect can be improved, and the user can hold the handle 2 more stably.

[0041] Preferably, the outer wall of the sealing sleeve 7 is provided with a limiting hole, which is used to avoid the control switch 5.

[0042] Understandably, to avoid interference between the sealing sleeve 7 and the control switch 5 on the side wall of the handle 2, a limiting hole is provided on the sealing sleeve 7 to allow the control switch 5 to pass through, so that the user can easily press the control switch 5 when holding the handle 2 with one hand. At the same time, the control switch 5 passing through the limiting hole can also achieve a stronger limiting effect on the sealing sleeve 7 by locking the control switch 5 into the limiting hole, so as to ensure that the sealing sleeve 7 can be continuously fitted on the handle 2 during long-term use and reduce the phenomenon that the sealing sleeve 7 is prone to displacement.

[0043] In some embodiments, please refer to Figure 4 As shown, the portable gripping device also includes a connecting pipe 4, a motor 8, a motor switch, and a first sealed bearing 9. The connecting pipe 4 is the main shaft of the motor 8, which is located in the mounting base 1. The first end of the connecting pipe 4 is connected to the vacuum mechanism 6 through the first sealed bearing 9, and the second end of the connecting pipe 4 is detachably connected to the suction cup connector 34. The motor switch is located on the handle 2 and is used to control the start and stop of the motor 8.

[0044] It is understood that in this preferred embodiment, the motor 8 drives the connecting pipe 4 to rotate (the connecting pipe 4 is the main shaft of the motor 8, which can be understood as a pipe-shaped connecting pipe 4 formed by a hollow channel inside the main shaft of the motor 8). The connecting pipe 4 can then drive the suction cup assembly 3 to rotate, so that the suction cup assembly 3 can pick up the item while driving the item to rotate, making the gripping device more functional and improving its practicality. For example, by using the suction cup assembly 3 to pick up rags and other items and rotate them, it is convenient to perform operations such as car washing or window cleaning, effectively improving cleaning power and efficiency. The connecting pipe 4 is connected to the vacuuming mechanism 6 through the first sealed bearing 9, which can ensure the stable implementation of the vacuuming operation.

[0045] The connecting pipe 4 is preferably connected to the pre-set opening at the front end of the mounting base 1 through a second sealing bearing, which can improve the sealing effect inside the mounting base 1, reduce the entry of sewage impurities into the mounting base 1, and help improve the stability of the operation of each component.

[0046] In other embodiments, please refer to Figure 1 , 2As shown in Figure 3, the suction cup assembly 3 includes a suction cup body 31 and a suction cup connector 34. The suction cup connector 34 is disposed on the suction cup body 31. The portable gripping device also includes a connecting tube 4. The first end of the connecting tube 4 is connected to the vacuum mechanism 6, and the second end of the connecting tube 4 is detachably connected to the suction cup connector 34.

[0047] It is understandable that the suction cup body 31 has a funnel-shaped cover structure, and a suction cup connector 34 is provided on the suction cup body 31. The suction cup connector 34 has a suction channel inside. The suction cup connector 34 and the connecting tube 4 are detachable, which facilitates the assembly and disassembly of the entire suction cup assembly 3.

[0048] Optionally, the suction cup connector 34 is a tubular structure. The inner wall of the suction cup connector 34 is provided with internal threads, and the outer wall of the second end of the connecting tube 4 is provided with external threads. The suction cup connector 34 and the second end of the connecting tube 4 are connected by threads, which makes it easy to disassemble and assemble the suction cup assembly 3 through the suction cup connector 34, and facilitates the subsequent maintenance, replacement and cleaning of the suction cup assembly 3.

[0049] Preferably, the connecting pipe 4 is a telescopic pipe structure.

[0050] It is understandable that by setting the connecting tube 4 as a telescopic tube structure, the position of the suction cup assembly 3 can be changed by extending or shortening the connecting tube 4, so that when the user holds the handle 2, the suction cup assembly 3 can be more easily inserted into different positions to grab different items, making it more convenient for the user to use and adapting to different grabbing needs.

[0051] Optionally, the connecting tube 4 includes an inner tube and an outer tube. The outer wall of the first end of the inner tube is provided with an external thread, and the inner wall of the first end of the outer tube is provided with an internal thread. The first end of the inner tube and the first end of the outer tube are connected by threads. The overall length of the connecting tube 4 can be adjusted by turning the inner tube or the outer tube without affecting the overall sealing effect of the connecting tube 4. This allows for adjustment of the installation position of the suction cup assembly 3 to adapt to more usage scenarios.

[0052] Preferably, please refer to Figure 2 , 3 As shown, the suction cup assembly 3 also includes a suction cup base plate 32, which is detachably connected to the suction cup body 31. The suction cup base plate 32 and the suction cup body 31 enclose a negative pressure cavity, and an air extraction hole 321 is provided on the suction cup base plate 32.

[0053] Understandably, by having the suction cup base plate 32 abut and adhere to the object to be grasped, the deformation of the suction cup body 31 can be reduced while the contact area between the suction cup base plate 32 and the object surface is increased, ensuring a precise fit between the suction cup base plate 32 and the object surface, effectively improving the stability of the suction cup assembly 3 in grasping the object. Furthermore, the suction cup base plate 32 is detachable, allowing the suction cup assembly 3 to adapt to the grasping needs of different objects, effectively improving the overall adaptability of the grasping device.

[0054] Optionally, the suction cup base plate 32 is made of a flexible material so that it can deform and easily adhere to the surface of an irregular object. This improves the adhesion between the suction cup base plate 32 and the object, ensuring that after the vacuum mechanism 6 evacuates the negative pressure cavity, the suction cup base plate 32 can adhere tightly to the object to be grasped, achieving a stable suction force and ensuring a firm grip on the object.

[0055] Optionally, a mounting retaining ring is provided on the outer wall of the suction cup base plate 32. The suction cup base plate 32 is fitted onto the bottom end of the suction cup body 31 through the mounting retaining ring. The mounting retaining ring and the suction cup body 31 are connected by bolts to facilitate the disassembly of the suction cup base plate 32. At the same time, a sealing ring is provided between the mounting retaining ring and the suction cup body 31 to improve the sealing effect between the mating surfaces of the mounting retaining ring and the suction cup body 31.

[0056] Preferably, please refer to Figure 2 As shown, the outer wall of the suction cup base plate 32 is provided with multiple anti-slip protrusions 322 at intervals, and the anti-slip protrusions 322 are arranged to avoid the air extraction hole 321.

[0057] Understandably, the anti-slip protrusions 322 are arranged to avoid the air extraction hole 321 to prevent affecting the vacuuming operation of the vacuuming mechanism 6 on the negative pressure inner cavity. The multiple anti-slip protrusions 322 spaced apart on the outer wall of the suction cup base plate 32 can effectively increase the friction between the suction cup base plate 32 and the surface of the object to be grasped. Combined with the suction cup base plate 32 made of flexible material, it can make the suction cup base plate 32 fit more tightly to the surface of the object and reduce the phenomenon that the suction cup base plate 32 is prone to slipping. Especially for objects with relatively smooth surfaces such as ceramic plates and glass, it can effectively improve the stability of the suction cup assembly 3 in grasping the object.

[0058] Optionally, the anti-slip protrusions 322 are made of rubber. Multiple sets of anti-slip protrusions 322 are arranged in a ring array. Since there is a gap between each set of anti-slip protrusions 322, when the suction cup base plate 32 comes into contact with the object surface and the vacuum mechanism 6 evacuates the negative pressure cavity, the suction cup base plate 32 deforms and fits more tightly against the object surface. At this time, each set of anti-slip protrusions 322 is squeezed, causing the anti-slip protrusions 322 to deform. The friction between the suction cup base plate 32 and the object surface can be increased by the anti-slip protrusions 322, thereby improving the overall stability of the suction cup assembly 3 in grasping the object. It is especially suitable for grasping objects with relatively smooth surfaces such as glass or ceramic discs.

[0059] Preferably, please refer to Figure 1 , 2 As shown in Figure 3, a lifting member 33 is provided at the edge of the suction cup body 31. The lifting member 33 is used to lift the suction cup body 31 so that the suction cup assembly 3 can be separated from the object to be grasped.

[0060] It is understandable that by setting a lifting member 33 on the bottom outer wall of the suction cup body 31, when it is necessary to quickly peel the suction cup body 31 from the surface of the object after the gripping is completed, a part of the suction cup body 31 can be lifted by pulling the lifting member 33, so that the pressure in the negative pressure cavity inside the suction cup body 31 can be quickly balanced internally and externally, and the suction cup assembly 3 can be separated from the surface of the object more easily.

[0061] Optionally, the lifting element 33 has a ring or hook structure, which allows the user to easily pull the lifting element 33 manually.

[0062] Optionally, multiple lifting elements 33 are provided, and the multiple lifting elements 33 are arranged in a circular array on the outer wall of the suction cup body 31, so that the user can easily lift different parts of the suction cup body 31 through the lifting elements 33 in sequence, so that the suction cup body 31 can be smoothly detached from the surface of the object.

[0063] Preferably, please refer to Figure 3 As shown, a heat dissipation cavity 11 is provided inside the rear end of the mounting base 1, and heat dissipation fins are provided on the inner wall of the mounting base 1.

[0064] It is understandable that by setting a heat dissipation cavity 11 at the rear end of the mounting base 1, and by setting heat dissipation fins on the inner wall of the mounting base 1, the heat dissipation effect of the mounting base 1 can be effectively guaranteed, which is conducive to the rapid dissipation of heat in the mounting base 1, ensuring that the vacuum mechanism 6 in the mounting base 1 can operate stably, and is conducive to the long-term stable use of the gripping device.

[0065] Optionally, the rear side wall of the mounting base 1 is provided with heat dissipation holes, which can quickly dissipate the heat from the heat dissipation cavity 11 to avoid overheating in the mounting base 1 and ensure the stability of the vacuum mechanism 6 in the mounting base 1.
