[0002] The suction lifter is a fast, safe and convenient automated equipment. It is classified as a lift abroad. It uses the principle of vacuum adsorption and uses a vacuum pump or vacuum blower as a vacuum source to generate a vacuum at the suction cup end, thereby firmly sucking up various workpieces and moving the workpieces to the designated location through a rotatable robotic arm or crane.

[0003] When using a suction lifter, it is usually necessary to carry goods of different sizes, weights and materials. At this time, the suction cup needs to be replaced according to the size, weight and material of the goods. However, some existing suction lifters are complicated to operate and not convenient enough when replacing the suction cup. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a quick-change structure of a suction cup of a one-handed vacuum tube suction lifter.

[0009] Through the above technical solution, the sealing gasket can ensure the sealing of the connection when the air hole is connected to the vacuum tube, thereby ensuring the stability of the suction cup when adsorbing the goods.

[0010] As a further improvement of the above solution, four first fixing bolts are provided, and the four first fixing bolts are symmetrically arranged around the center of the fixing seat. Two second fixing bolts are provided, and the two second fixing bolts are symmetrically arranged around the center of the fixing seat.

[0014] As a further improvement of the above solution, four limiting bolts are provided, and the positions of the limiting bolts correspond to the positions of the fixing grooves.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The utility model rotates the handle counterclockwise, and because the left end of the threaded tube is arc-shaped, it will move outward during the rotation of the handle, thereby driving the limit rod to move outward, so that the limit rod is retracted into the threaded tube. The limit tube can prevent the limit rod from shaking up and down during the movement. At this time, the limit rod will not block the limit bolt. The suction cup is then rotated, and the suction cup drives the limit bolt to rotate. The suction cup is then pulled downward, and the suction cup is disengaged from the fixing ring. At the same time, the suction cup drives the limit bolt to move downward, so that the limit bolt is disengaged from the fixing groove, thereby completing the removal of the suction cup. Similarly, a new suction cup can be installed on the fixing seat, so that the suction cup is more convenient to replace.

[0017] When the utility model is used, it can be connected to the vacuum tube through the air hole, and the sealing gasket in the sealing groove on the fixed seat can ensure the sealing during the connection process. At the same time, the suction cup is clamped with the fixing ring to further ensure the sealing of the device, thereby preventing the goods from being separated from the suction cup due to air leakage when transporting the goods.
