Description

Technical Field

[0001] This disclosure relates to the technical field of handheld suction cup devices for screen production, and in particular to a sealing structure and a handheld suction cup device for screen production. Background Technology

[0002] During the production or transportation of screens, manual handling and installation are required. This is especially true when moving larger screens, which is very troublesome. Operators need to pick up the screen from the side and avoid leaving fingerprints or other marks on it. This makes the screen handling operation time-consuming and laborious, greatly reducing the production efficiency of screens.

[0003] To address the aforementioned issues, some manufacturers have conducted further research and development. For example, existing patent CN209493065U discloses a handheld glass suction cup for glass production. This patent discloses a suction cup body with an annular adjustment groove on the inner bottom. A matching telescopic ring is located within the groove. The telescopic ring's extension and retraction, combined with a first one-way exhaust valve, allows air to escape from the suction cup body. Combined with the sealing effect of a rubber ring, this enables the suction cup body to effectively adhere to the glass. The suction cup body also features a first exhaust hole and a second exhaust hole, sealed with corresponding rubber plugs. These are connected to the rubber plugs via an adjustment rod. When suction is not needed, simply pulling the adjustment rod towards one side of the handle frame breaks the seal, thus eliminating the suction capacity and allowing the suction cup body to detach from the glass. This convenient and quick process significantly reduces the difficulty of glass handling and improves glass production efficiency.

[0004] However, during the process of the operator using the suction cup to adsorb the screen, the residual air inside the suction cup body will put pressure on the rubber stopper, which makes the rubber stopper prone to loosening or even falling off the air inlet under continuous air pressure. As a result, the rubber stopper cannot seal the air inlet, and thus the suction cup body cannot form an effective air pressure difference with the outside, which makes the suction cup unable to adsorb the screen normally. This not only greatly reduces the stability of the suction cup, but also greatly reduces the production efficiency of the screen. Utility Model Content

[0005] The purpose of this disclosure is to overcome the shortcomings of the prior art and provide a sealing structure and a handheld suction cup device for screen production that not only has better stability in use but also improves the production efficiency of screens.

[0006] The purpose of this disclosure is achieved through the following technical solution:

[0007] A sealing structure is used to be installed on the top of the suction cup body of a handheld suction cup device for screen production, the sealing structure including a frame and an elastic sealing component;

[0008] The frame is used to fix the top of the suction cup body. The elastic sealing component is disposed in the frame. The sealing end of the elastic sealing component is used to be opposite to the air inlet of the suction cup body. The sealing end of the elastic sealing component is used to seal the air inlet. The elastic end of the elastic sealing component is elastically connected to the frame so that the sealing end of the elastic sealing component is used to elastically press against the top of the suction cup body.

[0009] In one embodiment, the elastic sealing assembly includes a seal and an elastic element. The sealing end of the elastic sealing assembly is disposed on the seal, and the elastic end of the elastic sealing assembly is disposed on the elastic element. The first end of the seal is used to seal the air inlet, and the two ends of the elastic element are closed and elastically connected to the second end of the seal and the frame.

[0010] In one embodiment, the sealing structure further includes a lever assembly disposed within the frame. The lever assembly includes a pressing portion, a pivot portion, and an lifting portion that are fixed in sequence. The pivot portion is rotatably connected to the inner wall of the frame. The second end of the seal has an abutment flange, and the lifting portion abuts against and is supported on the bottom of the abutment flange.

[0011] In one embodiment, the frame has a communicating mounting cavity and a guide limiting groove. The first end of the seal is disposed in the guide limiting groove, and the second end of the seal is disposed in the mounting cavity. The bottom of the guide limiting groove has a connection port for communicating with the air inlet. The first end of the seal is disposed opposite to the connection port. When the first end of the seal seals the connection port, the first end of the seal seals and abuts against the bottom wall of the guide limiting groove.

[0012] In one embodiment, the elastic element is disposed within the mounting cavity, the inner wall of the mounting cavity forms a limiting groove, the first end of the elastic element is disposed within the limiting groove and elastically abuts against the bottom wall of the limiting groove, and the second end of the elastic element is sleeved on the second end of the sealing element and elastically abuts against the top of the abutting flange.

[0013] In one embodiment, the sealing structure further includes a pressing member, and the frame body also forms a clearance hole. The first end of the pressing member passes through the clearance hole and is disposed in the mounting cavity. The first end of the pressing member is disposed opposite to the lower pressing part and abuts against the top end of the lower pressing part. The second end of the pressing member protrudes from the outside of the frame body.

[0014] In one embodiment, the inner wall of the frame is further provided with a connecting rod, the pivot portion is provided with a connecting hole, the connecting rod passes through the connecting hole, and the connecting rod is slidably connected to the wall of the connecting hole.

[0015] In one embodiment, the first end of the seal is provided with an elastic sealing portion, which is disposed opposite to the connection port. When the seal is sealed to the connection port, the elastic sealing portion presses against the bottom wall of the guide limiting groove.

[0016] In one embodiment, the inner wall of the frame is further provided with a buffer member, which is disposed opposite to the bottom end of the pressing part.

[0017] A handheld suction cup device for screen production includes a suction cup body and a sealing structure as described in any of the above embodiments, wherein the sealing end of the elastic sealing component is disposed opposite to the air inlet of the suction cup body.

[0018] Compared with the prior art, this disclosure includes, but is not limited to, the following advantages:

[0019] 1. In the aforementioned sealing structure, the sealing end of the elastic sealing component is positioned opposite to the air inlet of the suction cup body. The sealing end of the elastic sealing component seals the air inlet, and its elastic end is elastically connected to the frame. This allows the sealing end of the elastic sealing component to elastically press against the top of the suction cup body. When the operator presses the suction end of the suction cup body against the screen, the residual gas inside the suction cup body continuously exerts a thrust away from the suction cup body on the sealing end of the elastic sealing component. The elastic end of the elastic sealing component, through its own elasticity, can press and limit the sealing end of the elastic sealing component to the top of the suction cup body, preventing the sealing end of the elastic sealing component from loosening due to the large thrust. This ensures that the sealing end of the elastic sealing component can reliably seal the air inlet, thereby creating an effective air pressure difference between the inside of the suction cup body and the outside, which greatly improves the stability of the suction cup device.

[0020] 2. When the screen is moved to the preset position, the operator only needs to apply a pushing force to the sealing end of the elastic sealing component in the direction away from the suction cup body. The sealing end of the elastic sealing component can then move away from the suction cup body through its own elastic deformation capability, so that the air inlet is open, allowing outside air to enter the suction cup body, thereby allowing the suction cup body to detach from the screen. When the operator stops applying the pushing force to the sealing end of the elastic sealing component, the sealing end of the elastic sealing component can be squeezed and limited to the top of the suction cup body through its own elastic performance, so that the sealing end of the elastic sealing component can reliably seal the air inlet, allowing the operator to squeeze the suction cup device to adhere to the screen again. Compared with the suction cups in the above-mentioned related technologies that require manual sealing of the air inlet with rubber plugs, the sealing end of the elastic sealing component of this disclosure can automatically seal the air inlet through its own elastic performance, thereby greatly improving the ease of use of the suction cup device and thus greatly improving the production efficiency of the screen.

[0030] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0031] like Figures 1 to 5As shown, a sealing structure 100 of one embodiment is used to be installed on the top of the suction cup body 200 of the handheld suction cup device 10 for screen production. The sealing structure 100 includes a frame 110 and an elastic sealing component 120. The frame 110 is fixed to the top of the suction cup body 200. The elastic sealing component 120 is disposed inside the frame 110. The sealing end of the elastic sealing component 120 is arranged opposite to the air inlet 210 of the suction cup body 200 and is used to seal the air inlet 210. The elastic end of the elastic sealing component 120 is elastically connected to the frame 110 so that the sealing end of the elastic sealing component 120 is elastically pressed against the top of the suction cup body 200 when the operator... During the process of squeezing and adsorbing the screen by the suction cup body 200, the residual gas inside the suction cup body 200 will continuously exert a pushing force away from the suction cup body 200 on the sealing end of the elastic sealing component 120. The elastic end of the elastic sealing component 120 can squeeze and limit the sealing end of the elastic sealing component 120 to the top of the suction cup body 200 through its own elastic properties, so as to prevent the sealing end of the elastic sealing component 120 from loosening due to the large pushing force. This allows the sealing end of the elastic sealing component 120 to reliably seal the air inlet 210, thereby creating an effective air pressure difference between the inside of the suction cup body 200 and the outside, which greatly improves the stability of the suction cup device 10.

[0032] When the screen is moved to the preset position, the operator only needs to apply a pushing force to the sealing end of the elastic sealing component 120 in a direction away from the suction cup body 200. The sealing end of the elastic sealing component 120 can then move away from the suction cup body 200 through its own elastic deformation capability, so that the air inlet 210 is in the open state, allowing outside air to enter the suction cup body 200, thereby allowing the suction cup body 200 to detach from the screen. When the operator stops applying the pushing force to the sealing end of the elastic sealing component 120, the sealing end of the elastic sealing component 120 can then move away from the suction cup body 200 through its elastic deformation capability. The elastic end of the sealing component 120 is compressed to the top of the suction cup body 200 by its own elasticity, so that the sealing end of the elastic sealing component 120 can reliably seal the air inlet 210. This allows the operator to press the suction cup device 10 to adhere to the screen again. Compared with the suction cups in the above-mentioned related technologies that require manual sealing of the air inlet 210 with a rubber plug, the sealing end of the elastic sealing component 120 of this disclosure can automatically seal the air inlet 210 by its own elasticity, thereby greatly improving the ease of use of the suction cup device 10 and thus greatly improving the production efficiency of the screen.

[0033] In this embodiment, when the screen needs to be moved, the suction end of the suction cup body 200 is pressed against the screen, and the residual gas inside the suction cup body 200 will be discharged through the gap between the suction cup body 200 and the screen. At the same time, the residual gas will also exert a pushing force on the sealing end of the elastic sealing component 120. The elastic end of the elastic sealing component 120 can squeeze and limit the sealing end of the elastic sealing component 120 to the top of the suction cup body 200 through its own elastic properties, so that the sealing end of the elastic sealing component 120 can reliably seal the air inlet 210, so that an effective air pressure difference can be formed between the inside of the suction cup body 200 and the outside, thereby enabling the suction end of the suction cup body 200 to reliably adsorb the screen.

[0034] When the screen is moved to the preset position, the operator only needs to apply a pushing force to the sealing end of the elastic sealing component 120 in a direction away from the suction cup body 200. The sealing end of the elastic sealing component 120 can then move away from the suction cup body 200 through its own elastic deformation capability, so that the air inlet 210 is in an open state, allowing outside air to enter the suction cup body 200, thereby allowing the suction cup body 200 to detach from the screen. When the operator stops applying the pushing force to the sealing end of the elastic sealing component 120, the sealing end of the elastic sealing component 120 can be squeezed and limited to the top of the suction cup body 200 through its own elastic performance, so that the sealing end of the elastic sealing component 120 can reliably seal the air inlet 210, allowing the operator to squeeze the suction cup device 10 to adhere to the screen again.

[0035] The aforementioned sealing structure 100, because the sealing end of the elastic sealing component 120 is arranged opposite to the air inlet 210 of the suction cup body 200, the sealing end of the elastic sealing component 120 is used to seal the air inlet 210, and the elastic end of the elastic sealing component 120 is elastically connected to the frame 110, so that the sealing end of the elastic sealing component 120 is used to elastically press against the top of the suction cup body 200. When the operator squeezes the suction cup body 200 to adsorb the screen, the residual gas inside the suction cup body 200 will continuously flow into the sealing end of the elastic sealing component 120. A thrust is applied to the end of the suction cup 200 away from the suction cup body 200. The elastic end of the elastic sealing component 120 can squeeze and limit the sealing end of the elastic sealing component 120 to the top of the suction cup body 200 through its own elastic properties, so as to prevent the sealing end of the elastic sealing component 120 from loosening due to the large thrust. This allows the sealing end of the elastic sealing component 120 to reliably seal the air inlet 210, thereby enabling an effective air pressure difference between the inside of the suction cup body 200 and the outside, which greatly improves the stability of the suction cup device 10.

[0036] When the screen is moved to the preset position, the operator only needs to apply a pushing force to the sealing end of the elastic sealing component 120 in a direction away from the suction cup body 200. The sealing end of the elastic sealing component 120 can then move away from the suction cup body 200 through its own elastic deformation capability, so that the air inlet 210 is in the open state, allowing outside air to enter the suction cup body 200, thereby allowing the suction cup body 200 to detach from the screen. When the operator stops applying the pushing force to the sealing end of the elastic sealing component 120, the sealing end of the elastic sealing component 120 can then move away from the suction cup body 200 through its elastic deformation capability. The elastic end of the sealing component 120 is compressed to the top of the suction cup body 200 by its own elasticity, so that the sealing end of the elastic sealing component 120 can reliably seal the air inlet 210. This allows the operator to press the suction cup device 10 to adhere to the screen again. Compared with the suction cups in the above-mentioned related technologies that require manual sealing of the air inlet 210 with a rubber plug, the sealing end of the elastic sealing component 120 of this disclosure can automatically seal the air inlet 210 by its own elasticity, thereby greatly improving the ease of use of the suction cup device 10 and thus greatly improving the production efficiency of the screen.

[0037] like Figure 1 As shown in the figure, the adsorption principle and structure of the suction cup body 200 in this embodiment are existing technologies and will not be described in detail here.

[0038] like Figures 1 to 4 As shown, in one embodiment, the elastic sealing assembly 120 includes a sealing element 121 and an elastic element 122. The sealing end of the elastic sealing assembly 120 is disposed on the sealing element 121, and the elastic end of the elastic sealing assembly 120 is disposed on the elastic element 122. The first end of the sealing element 121 is used to seal the air inlet 210. The two ends of the elastic element 122 are closed and elastically connected to the second end of the sealing element 121 and the frame 110, so that the elastic element 122 can squeeze and limit the sealing element 121 to the top of the suction cup body 200 through its own elastic properties, avoiding the phenomenon that the first end of the sealing element 121 will loosen due to the large thrust, so that the first end of the sealing element 121 can reliably seal the air inlet 210, thereby greatly improving the stability of the suction cup device 10.

[0039] like Figures 1 to 4 As shown, in this embodiment, the elastic element 122 is a spring or elastic silicone to give the elastic element 122 better elastic properties.

[0040] like Figures 1 to 4As shown, in one embodiment, the sealing structure 100 further includes a lever assembly 130, which is disposed within the frame 110. The lever assembly 130 includes a pressing portion 131, a pivot portion 132, and an lifting portion 133, which are fixed in sequence. The pivot portion 132 is rotatably connected to the inner wall of the frame 110. The second end of the sealing member 121 forms an abutting flange 1212. The lifting portion 133 abuts against and is supported on the bottom of the abutting flange 1212. When the operator moves the screen to a preset position, the operator only needs to press the pressing portion 131, and the pressing portion 131 can rotate relative to the frame 110 through the pivot portion 132, so that the pressing portion 131 can drive the lifting portion 133 relative to the frame 110 through the pivot portion 132. Rotating the 10-axis causes the lifting part 133 to push the sealing member 121 away from the suction cup body 200, thereby causing the suction cup body 200 to detach from the screen due to the entry of external air into the suction cup body 200. When the pressing part 131 is stopped, the elastic member 122 can push the sealing member 121 towards the air inlet 210 through its own elastic properties, so that the first end of the sealing member 121 can be squeezed and limited to the top of the suction cup body 200, so that the first end of the sealing member 121 can seal the air inlet 210, thereby allowing the operator to squeeze the suction end of the suction cup body 200 onto the screen again, thus greatly improving the ease of use of the suction cup device 10.

[0041] like Figures 1 to 4 As shown, in this embodiment, the pressing part 131, the pivot part 132 and the lifting part 133 are integrally formed to improve the structural compactness of the lever assembly 130.

[0042] like Figures 1 to 4 As shown, in one embodiment, the frame 110 has a communicating mounting cavity 111 and a guide limiting groove 112. A first end of the seal 121 is disposed within the guide limiting groove 112, and a second end of the seal 121 is disposed within the mounting cavity 111. The bottom of the guide limiting groove 112 has a connection port 1121 for communicating with the air inlet 210. The first end of the seal 121 is positioned opposite to the connection port 1121, allowing the seal 121 to move along the guiding direction of the guide limiting groove 112 in a direction away from or near the connection port 1121. At the same time, the guide limiting groove 112 can also limit the sealing end of the elastic sealing component 120, so that the first end of the sealing member 121 is squeezed and limited at the connection port 1121 of the suction cup body 200; when the first end of the sealing member 121 seals the connection port 1121, the first end of the sealing member 121 is sealed and abutted against the bottom wall of the guide limiting groove 112, so as to prevent external gas from entering the interior of the suction cup body 200 through the gap between the bottom wall of the guide limiting groove 112 and the first end of the sealing member 121, thereby greatly improving the stability of the suction cup device 10.

[0043] like Figures 1 to 4 As shown, in one embodiment, the elastic member 122 is disposed in the mounting cavity 111, and the inner wall of the mounting cavity 111 forms a limiting groove 1111. The first end of the elastic member 122 is disposed in the limiting groove 1111 and elastically abuts against the bottom wall of the limiting groove 1111, so that the first end of the elastic member 122 can be reliably limited in the limiting groove 1111, preventing the elastic member 122 from sliding relative to the frame 110 when subjected to pressure. The second end of the elastic member 122 is sleeved on the second end of the sealing member 121 and elastically abuts against the top of the abutting flange 1212, so that the second end of the elastic member 122 can be reliably limited in the second end of the sealing member 121, preventing the elastic member 122 from sliding relative to the second end of the sealing member 121 when subjected to pressure, further improving the stability of the suction cup device 10.

[0044] like Figures 1 to 4 As shown, in one embodiment, the sealing structure 100 further includes a pressing member 140, and the frame 110 also has a clearance hole. The first end of the pressing member 140 passes through the clearance hole and is disposed in the mounting cavity 111. The first end of the pressing member 140 is disposed opposite to the pressing part 131 and abuts against the top end of the pressing part 131. The second end of the pressing member 140 protrudes from the outside of the frame 110. When the operator moves the screen to the preset position, the operator only needs to press the pressing member 140, which can push the pressing part 131 to rotate relative to the frame 110, so that the pressing part 131 can drive the lifting part 133 to rotate relative to the frame 110 through the pivot part 132, so that the lifting part 133... 3. The sealing member 121 can be pushed to move away from the suction cup body 200, so that the suction cup body 200 is detached from the screen due to the entry of external gas into the suction cup body 200. When the pressing member 140 is stopped, the elastic member 122 can push the sealing member 121 to move closer to the air inlet 210 through its own elastic properties, so that the first end of the sealing member 121 can be squeezed and limited to the top of the suction cup body 200, so that the first end of the sealing member 121 can seal the air inlet 210, so that the operator can squeeze the suction end of the suction cup body 200 to the screen again, thereby greatly improving the ease of use of the suction cup device 10.

[0045] like Figures 1 to 4 As shown, in one embodiment, a connecting rod 113 is formed on the inner wall of the frame 110, and a connecting hole 1321 is formed on the pivot portion 132. The connecting rod 113 passes through the connecting hole 1321 and is slidably connected to the hole wall of the connecting hole 1321 so that the pivot portion 132 can rotate relative to the frame 110, so that the pressing portion 131 and the lifting portion 133 can rotate relative to the frame 110 through the pivot portion 132.

[0046] like Figures 1 to 4 As shown, in one embodiment, the first end of the seal 121 is provided with an elastic sealing portion 1211. The elastic sealing portion 1211 is disposed opposite to the connection port 1121. When the seal 121 seals the connection port 1121, the elastic sealing portion 1211 is press-fitted against the bottom wall of the guide limiting groove 112. This allows the elastic sealing portion 1211 to press and limit the first end of the seal 121 against the bottom wall of the guide limiting groove 112 when the elastic member 122 presses and limits the first end of the seal 121 against the bottom wall of the guide limiting groove 112. This ensures that the elastic sealing portion 1211 fits tightly against the bottom wall of the guide limiting groove 112, further preventing external air from entering the suction cup body 200 through the gap between the elastic sealing portion 1211 and the bottom wall of the guide limiting groove 112. Consequently, the suction end of the suction cup body 200 can be firmly attached to the screen, greatly improving the stability of the suction cup device 10.

[0047] like Figures 1 to 4 As shown, in one embodiment, the inner wall of the frame 110 is also provided with a buffer 114. The buffer 114 is disposed opposite to the bottom end of the pressing part 131 so that when the operator presses the top of the pressing part 131, the buffer 114 can buffer the pressing part 131, avoiding damage or even destruction of the pressing part 131 due to direct rigid collision with the inner wall of the frame 110, thereby greatly reducing the maintenance cost of the suction cup device 10.

[0048] like Figures 1 to 4 As shown, in this embodiment, the buffer 114 is a buffer cotton, a silicone buffer, or a rubber buffer, so that the buffer 114 has a better buffering capacity.

[0049] This disclosure also provides a handheld suction cup device 10 for screen production, including a suction cup body 200 and a sealing structure 100 as described in any of the above embodiments, wherein the sealing end of the elastic sealing component 120 is disposed opposite to the air inlet 210 of the suction cup body 200.

[0050] Compared with the prior art, this disclosure includes, but is not limited to, the following advantages:

[0051] 1. In the aforementioned suction cup device 10, the sealing end of the elastic sealing component 120 is positioned opposite to the air inlet 210 of the suction cup body 200, and the sealing end of the elastic sealing component 120 is used to seal the air inlet 210. The elastic end of the elastic sealing component 120 is elastically connected to the frame 110, so that the sealing end of the elastic sealing component 120 is used to elastically press against the top of the suction cup body 200. When the operator squeezes the suction cup body 200 to adsorb the screen, the residual gas inside the suction cup body 200 will continuously flow into the sealing end of the elastic sealing component 120. A thrust is applied to the end of the suction cup 200 away from the suction cup body 200. The elastic end of the elastic sealing component 120 can squeeze and limit the sealing end of the elastic sealing component 120 to the top of the suction cup body 200 through its own elastic properties, so as to prevent the sealing end of the elastic sealing component 120 from loosening due to the large thrust. This allows the sealing end of the elastic sealing component 120 to reliably seal the air inlet 210, thereby enabling an effective air pressure difference between the inside of the suction cup body 200 and the outside, which greatly improves the stability of the suction cup device 10.

[0052] 2. When the screen is moved to the preset position, the operator only needs to apply a pushing force to the sealing end of the elastic sealing component 120 in a direction away from the suction cup body 200. The sealing end of the elastic sealing component 120 can then move away from the suction cup body 200 through its own elastic deformation capability, so that the air inlet 210 is in the open state, allowing outside air to enter the suction cup body 200, thereby allowing the suction cup body 200 to detach from the screen. When the operator stops applying the pushing force to the sealing end of the elastic sealing component 120, the sealing end of the elastic sealing component 120 can then move away from the suction cup body 200 through its own elastic deformation capability, so that the air inlet 210 is in the open state, allowing outside air to enter the suction cup body 200, thereby allowing the suction cup body 200 to detach from the screen. The elastic end of the elastic sealing component 120 is compressed to the top of the suction cup body 200 by its own elasticity, so that the sealing end of the elastic sealing component 120 can reliably seal the air inlet 210. This allows the operator to press the suction cup device 10 to adhere to the screen again. Compared with the suction cups in the above-mentioned related technologies that require manual sealing of the air inlet 210 with a rubber plug, the sealing end of the elastic sealing component 120 of this disclosure can automatically seal the air inlet 210 by its own elasticity, thereby greatly improving the ease of use of the suction cup device 10 and thus greatly improving the production efficiency of the screen.
