At the same time, the collision between the suction cup and the iron part when the suction cup adsorbs the iron part cannot be well alleviated by the existing magnetic suction cup. This collision may cause damage to the suction cup itself or its surrounding parts, thereby reducing the service life of the suction cup and may cause accidental damage or production line shutdown.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Specifically, when the angle of the mounting seat 21 needs to be adjusted, the rotating shaft 20 and the turntable 19 are driven to rotate by rotating the mounting seat 21. The rotation of the turntable 19 drives the block 22 to slide on the inclined inner wall surface of the limit ring 18, and the sliding resistance of the block 22 is increased by the inclined surface. During the sliding process, the block 22 continuously pushes the top plate 25, and the top plate 25 compresses the third spring 24 through the connecting ring buckle 23, thereby stabilizing the rotation of the mounting seat 21. This makes it more stable and reliable to adjust the angle of the mounting seat 21. In this way, the angle of the suction cup mounting piece can be easily adjusted, which facilitates the overall installation of the suction cup and improves the convenience of installation. At the same time, the installation efficiency and convenience of the suction cup are improved, while its scope of application is expanded to meet the different needs of users.

[0026] Reference Figure 1 and Figure 2 The upper surface of the suction cup body 1 is fixedly connected with a fixing plate 2, and the outer wall of the fixing plate 2 is fixedly connected with a push rod 3; the top of the outer wall of the push rod 3 is fixedly connected with a push plate 4, and the outer wall of the push plate 4 is fixedly connected with a sealing plug 5; the outer wall of the push plate 4 is slidably connected with a sleeve 6, and the outer wall of the sleeve 6 is fixedly connected to a limiting plate 13; a first spring 7 is arranged inside the sleeve 6, one end of the first spring 7 is fixedly connected to the inside of the sleeve 6, and the other end of the first spring 7 is fixedly connected to the upper surface of the push plate 4; the outer walls of the push rod 3 and the sleeve 6 are both sleeved with a second spring 8, one end of the second spring 8 is fixedly connected to the outer wall of the fixing plate 2, and the other end of the second spring 8 is fixedly connected to the outer wall of the limiting plate 13; the upper surface of the suction cup body 1 is fixedly connected with a support plate 9, and the upper surface of the support plate 9 is fixedly connected with a plurality of fixed seats 10, and the lower surface of the support platform 14 is fixedly connected with a fixed ball 12, and the interior of the fixed ball 12 is fixedly connected with a plurality of chains 11, and the outer wall of the chain 11 is fixedly connected to the interior of the fixed seat 10;

[0027] Specifically, when it is necessary to reduce the force exerted by the collision on the suction cup body 1, when the suction cup body 1 is adsorbed and collided with the iron piece, the suction cup body 1 will push the push rod 3 to slide inside the sleeve 6, and at the same time compress the first spring 7, which plays a preliminary force buffering role. The fixed plate 2 and the limit plate 13 will directly compress the second spring 8 to further alleviate the force. This reduces the impact of the collision on the suction cup body 1. When the suction cup body 1 is pulled back, the push plate 4 is sealed by the sealing plug 5 to the inside of the sleeve 6, so that the air pressure inside the sleeve 6 can reduce the pull-back range of the push plate 4, thereby reducing the activity of the suction cup body 1 pulling back. In addition, the support platform 14 further strengthens the connection between the suction cup body 1 and the support platform 14 through the connection between the chain 11 and the fixed seat 10, ensuring the stability and safety of the suction cup body 1 when a collision occurs. This not only improves the safety of the suction cup and extends its service life, but also effectively protects the adsorbed workpiece or iron piece. Thereby, the effect of reducing the force of the collision on the suction cup body 1 and its surrounding parts is achieved, the safety and reliability of the suction cup are guaranteed, and its service life is extended.

[0028] Working principle: when the angle of the mounting seat 21 needs to be adjusted, the mounting seat 21 is rotated to drive the rotating shaft 20 and the rotating disk 19 to rotate, thereby driving the block 22 to slide on the inner wall surface of the limiting ring 18. Since the inner wall of the limiting ring 18 is set as an inclined surface, the sliding resistance of the block 22 can be increased, and then the block 22 will continuously push the top plate 25 during the sliding process, so that the top plate 25 can be compressed by the connecting ring buckle 23 to the third spring 24, thereby making the rotation of the mounting seat 21 more stable, thereby achieving the effect of adjusting the angle of the suction cup mounting part, facilitating the overall installation of the suction cup, improving the convenience of the suction cup, and expanding the application range of the suction cup. When it is necessary to reduce the force brought to the suction cup body 1 by the collision, the suction cup body 1 is adsorbed and collides with the iron piece. The disc body 1 will push the push rod 3 to slide inside the sleeve 6, and at the same time compress the first spring 7, thereby preliminarily buffering the force, while the fixed plate 2 and the limit plate 13 will directly compress the second spring 8, so that the two second springs 8 can further alleviate the force. At the same time, when the suction cup body 1 is pulled back, the push plate 4 is sealed to the inside of the sleeve 6 by the sealing plug 5, so that the air pressure inside the sleeve 6 can reduce the pull-back range of the push plate 4, and then reduce the pull-back activity of the suction cup body 1. The support platform 14 is connected to the fixed seat 10 through the chain 11, so that the connection between the suction cup body 1 and the support platform 14 can be made stronger, thereby achieving the effect of reducing the collision force generated by the iron parts during adsorption, improving the safety of the suction cup, and extending the service life of the suction cup.
