Magnetic stands mostly use suction cups to fix them to the plane of the support. However, the existing suction cups are not strong enough and are not convenient to fix and remove. Utility Model Content

[0003] This application aims to provide a suction cup assembly that is simple in structure, easy to install, and reduces manufacturing costs.

[0004] This application is achieved through the following technical solution.

[0005] The technical solution of this application is to provide a suction cup assembly, including a suction cup and a fixing member. The first concave surface of the suction cup is provided with a groove, and a raised pressing part is provided in the middle of the groove. Multiple through first holes and one through second hole are provided around the pressing part in the groove. The second surface of the suction cup is provided with a boss corresponding to the groove.

[0006] The fastener is fitted into the groove, and the fastener is provided with a plurality of screw posts, which are inserted into the first through hole; the fastener is also provided with an exhaust port, which is inserted into the second through hole; the fastener is also provided with an avoidance hole for avoiding the pressing part.

[0007] The technical advantages of this solution are that the suction cup is installed using a fixing component, which has screw posts for fixing with screws, eliminating the need for glue. This makes installation and disassembly convenient. The fixing component and the suction cup can seal the first and second through holes on the suction cup. The fixing component has an exhaust port for connecting an air extraction device. This suction cup assembly has a simple structure, is easy to install, and reduces manufacturing costs.

[0008] In one embodiment of this technical solution, at least one raised strip is provided at the bottom edge of the groove to surround the through hole, and the raised strip has a closed structure with its ends connected. The contact between the raised strip and the fixing member increases the sealing performance and prevents air leakage between the first through hole and the second through hole.

[0009] In one embodiment of this technical solution, an annular groove is further formed within the groove surrounding the pressing portion, and the fixing member is provided with an annular protrusion that mates with the annular groove. Thus, the engagement of the annular groove and the annular protrusion increases the stability of the suction cup fixation.

[0010] Another technical solution of this application is to provide an electric suction cup device, comprising:

[0012] As described above, in the suction cup assembly, the boss of the suction cup mates with the base, and the screw post of the fixing member is connected to the base by screws to clamp the suction cup and seal the first through hole and the second through hole; an air extraction assembly is provided in the cavity, and the air extraction assembly is connected to the exhaust port and is used to evacuate the suction cup.

[0013] A switch assembly is disposed in the cavity, the switch assembly abutting against the pressing part, and the switch assembly is used to activate the operation of the air extraction assembly.

[0014] Thus, the operation of the suction component is started by using a switch assembly. The center of the suction cup is in contact with the switch assembly through a pressing part. When the suction cup is pressed on the plane, the pressing part is squeezed and triggers the switch assembly to start the suction operation. The suction component can be set to automatically stop after a certain suction time. The suction cup is easy to fix and operate.

[0015] In one embodiment of this technical solution, the air extraction assembly includes an air extraction cylinder and a motor. The air extraction cylinder is provided with an air extraction port, which is connected to the exhaust port through a pipe.

The vent button abuts against the vent valve, and the vent valve is configured to be normally closed and open when the vent button is pressed.

[0017] In one embodiment of this technical solution, the switching assembly includes a micro switch, a push rod, and a spring. One end of the push rod abuts against the pressing part, and the other end abuts against the spring. The push rod is provided with a trigger part.

[0018] When the pressing part is squeezed to move the top rod, the trigger part will abut against and trigger the micro switch, which is used to control the start of the air extraction component.

[0019] Another technical solution of this application is to provide a magnetic holder, comprising:

[0020] The electric suction cup device as described above;

[0021] A folding arm is hinged at one end to the base;

[0022] A magnetic base is hinged to the other end of the folding arm. The magnetic base has a bearing plane for supporting objects. The magnetic base has a magnet assembly inside, which is used to magnetically attract and confine the object on the bearing plane.

[0023] In one embodiment of this technical solution, the magnetic base is provided with a receiving cavity for accommodating the folding arm.

[0024] In one embodiment of this technical solution, the magnetic base includes a main shell, a connecting plate, and a decorative cover plate. The connecting plate and the decorative cover plate are both connected to the main shell and form an inner cavity for accommodating the magnet assembly. The folding arm is connected to the connecting plate.

[0025] In one embodiment of this technical solution, the base is provided with a rotatable turntable, the folding arm is hinged to the turntable, and a rotation positioning structure for rotation positioning is provided between the turntable and the base.

[0026] In one embodiment of this technical solution, the rotary positioning structure includes a plurality of positioning recesses on the turntable and a positioning component on the base.

[0043] The technical solutions of some embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0045] Example 1

[0046] like Figures 1 to 8 As shown in the figure, this embodiment is an electric suction cup device 10, which is used to adhere to a flat surface. The electric suction cup device 10 includes a base 11, a suction cup assembly 13, an air extraction assembly 14, and a switch assembly 15. The base 11 has a cavity 101, and other components, such as a bracket, can also be connected to the base 11.

[0047] In this embodiment, the suction cup assembly 13 includes a suction cup 132 and a fixing member 131. The first concave surface of the suction cup 132 is provided with a groove 1322, and a protruding pressing part 1321 is provided in the middle of the groove. Multiple through holes 1323 and one through hole 1324 are provided around the pressing part in the groove 1322. The second surface of the suction cup 132 is provided with a boss 1325 corresponding to the groove 1322.

[0048] The fastener 131 is fitted into the groove 1322. The fastener 131 is provided with a plurality of screw posts 1311, which are inserted into the first through hole 1323. The fastener 131 is also provided with an exhaust port 1312, which is inserted into the second through hole 1324. The fastener 131 is also provided with an avoidance hole 1313 for avoiding the pressing part.

[0049] Thus, the fixing member 131 passes through the suction cup 132 via the screw post 1311 and is connected to the bottom cover 12 by screws, clamping the suction cup 132 between the fixing member 131 and the bottom cover 12, while sealing the first through hole and the second through hole on the suction cup 132. The fixing member 131 serves to fix the suction cup 132.

[0050] Furthermore, two raised strips 1326 are provided on the bottom edge of the groove 1322 to surround the through hole. The raised strips 1326 form a closed structure with their ends connected. The contact between the raised strips 1326 and the fixing member 131 increases the sealing performance and prevents air leakage between the first and second through holes. An annular groove 1327 is also formed in the groove to surround the pressing part. The fixing member is provided with an annular protrusion 1314 that matches the annular groove. The cooperation between the annular groove 1327 and the annular protrusion 1314 increases the stability of the suction cup 132.

[0051] For example, the pressing part 1321 is cylindrical or frustum-shaped. The height of the pressing part 1321 is lower than the edge of the suction cup 132. The pressing part 1321 passes through the clearance hole 1313. When the pressing part 1321 is pressed, it will be displaced. The base 11 includes a bottom cover 12. The boss of the suction cup 132 cooperates with the outer bottom surface of the bottom cover 12. The four edges of the suction cup 132 are suspended and there is a certain distance between them and the bottom cover 12. The suction cup 132 is made of soft plastic material, such as silicone or rubber. The fixing member 131 is made of hard material. The suction cup 132 is disc-shaped.

[0052] In this embodiment, the vacuum assembly 14 is installed inside the cavity 101 of the base 11. The vacuum assembly 14 is connected to the exhaust port 1312 and is used to evacuate the suction cup 132. The vacuum assembly 14 includes a vacuum cylinder 141 and a motor 142. The vacuum cylinder 141 is provided with a vacuum port 1411, which is connected to the exhaust port 1312 through a pipe. The vacuum cylinder 141 adopts a piston structure, and its structure and working principle are existing technologies. The motor 142 is used to drive the vacuum cylinder 141 to perform vacuuming operations.

[0053] When it is necessary to release the vacuum in suction cup 132, it is necessary to connect the inside of suction cup 132 with the outside. For this purpose, a vent valve 1412 connected to the vent port 1411 is provided on the vent cylinder 141. For ease of operation, a vent button 1413 is provided on the base 11. The vent button 1413 is in contact with the vent valve 1412. The vent valve 1412 is configured to be normally closed and opens when the vent button 1413 is pressed, so that outside air enters the vent cylinder from the vent valve 1412 and then enters the connected suction cup 132.

[0054] It should be noted that the air extraction assembly 14 also includes a circuit board 143 and a battery 144 for controlling the motor 142. The circuit board 143 and the battery 144 are both located inside the cavity 101. A charging interface is provided on the circuit board 143. The battery 144 is electrically connected to the circuit board 143. The circuit board 143 is electrically connected to the motor 142. The battery 144 provides power to the motor 142.

[0055] In this embodiment, the switch assembly 15 is used to activate the operation of the suction assembly 14. The switch assembly 15 includes a micro switch 151, a push rod 152, and a spring 153. The micro switch 151, push rod 152, and spring 153 are all disposed inside the cavity 101. The micro switch 151 is fixed inside the bottom cover 12 and is electrically connected to the circuit board 143. One end of the push rod 152 passes through the bottom cover 12 and abuts against the upper end of the pressing part 1321. The other end of the push rod 152 is connected to the spring 153. When the spring 153 is compressed and pressed against the base 11 and the push rod 152, the spring 153 is used to reset the push rod 152. The side wall of the push rod 152 is provided with a trigger part 1521, which is a protrusion of the push rod 152. When the pressing part 1321 pushes the push rod 152 to move, the trigger part 1521 will press against and trigger the micro switch 151. The micro switch 151 is used to open so that the circuit board 143 controls the start motor 142 to perform air extraction.

[0056] It should be noted that when the suction cup 132 is pressed on the flat surface, the pressing part 1321 will be squeezed and trigger the micro switch 151. After the micro switch 151 is triggered, the motor 142 will start running, so that the vacuum cylinder 141 performs a vacuum operation, so that the suction cup 132 can be adsorbed on the flat surface. The vacuuming time is preset on the circuit board 143, such as 2 seconds. After the vacuuming time ends, the circuit board 143 automatically disconnects the power supply to the motor 142, so that the motor 142 stops.

[0061] An annular groove 112 coaxial with the rotating shaft 111 is formed on the base 11, and a convex ring 172 coaxial with the shaft hole 171 is formed on the turntable 17. The convex ring 172 cooperates with the annular groove 112 to increase the rotational stability of the turntable 17. The rotational positioning structure includes multiple positioning recesses 173 on the turntable 17 and a positioning component 18 on the base 11. The positioning recesses 173 are located on the convex ring 172, and the positioning component 18 cooperates with the positioning recesses 173 to realize the rotational positioning of the turntable 17.
