[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 in use, a suction lifter usually needs to carry goods of different sizes, weights and materials, so the suction lifter needs to replace different suction cups according to the size, weight and material of the goods. However, some existing suction lifters are difficult to operate and waste time when replacing the suction cups. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a two-handed vacuum tube suction lifting machine with a suction cup that can be quickly replaced.

[0006] Through the above technical solution, the knob is rotated, the knob drives the threaded rod to rotate, and the rotation of the threaded rod causes the threaded rod to move along the threaded barrel, thereby changing the length of the threaded rod in the threaded barrel.

[0007] As a further improvement of the above scheme, the air hole is located at the central axis of the mounting plate, the air hole passes through the bottom wall of the mounting plate and extends to the bottom of the mounting plate, the length of the threaded rod is greater than the length of the threaded tube, and two baffles are provided, and the two baffles are symmetrically arranged around the center of the mounting plate.

[0009] Through the above technical solution, the sealing groove is in contact with the mounting plate and the fixing plate, so that the sealing performance of the device can be ensured.

[0010] As a further improvement of the above solution, bolts are threadedly connected on the fixing plate, the fixing plate is fixedly connected to the mounting plate by bolts, a docking plate is provided at the bottom of the fixing plate, and the top of the docking plate is in contact with the bottom of the fixing plate.

[0011] Through the above technical solution, the limiting plate can be fixed between the mounting plate and the fixing plate by bolts to prevent the limiting plate from moving.

A circular groove is opened on the docking plate, and the diameter of the circular groove is larger than the diameter of the fixing plate.

[0013] Through the above technical solution, the connecting rod is driven to rotate by the rotating rod, and the connecting rod drives the installation rod to rotate, thereby driving the gear to rotate around the rotating rod.

[0014] As a further improvement of the above scheme, a fixing hole is opened on the docking plate, an air inlet pipe is fixedly connected to the inside of the docking plate, both ends of the air inlet pipe pass through the side wall of the docking plate and extend, the air inlet pipe is located inside the air hole, and a suction cup is fixedly connected to the outer wall of the air inlet pipe.

[0015] Through the above technical solution, the docking plate can be quickly fixed on the mounting plate through the fixing holes, thereby facilitating the disassembly of the docking plate.

[0016] As a further improvement of the above solution, two fixing holes are provided, and the two fixing holes are symmetrically arranged around the center of the docking plate, and the diameter of the air inlet pipe is smaller than the diameter of the air hole.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model rotates the knob clockwise to drive the threaded rod to rotate. The rotation of the threaded rod causes the threaded rod to move upward along the threaded tube, so that the bottom end of the threaded rod is separated from the fixing hole on the docking plate. The docking plate is then rotated in the direction without the baffle plate to make the docking plate and the mounting plate vertical. The docking plate is then pulled downward, and the docking plate drives the air inlet pipe downward, so that the air inlet pipe is separated from the air hole, and the suction cup can be removed. Conversely, the installation of the suction cup can be completed, which can greatly save the time required for replacing the suction cup.

[0019] The utility model fixes the sealing gasket in the sealing groove and fixes the limiting plate between the fixing plate and the mounting plate by bolts, so that the top of the sealing gasket can be in close contact with the bottom of the mounting plate, which can effectively ensure the sealing of the device and prevent the device from leaking during use and causing the goods to separate from the suction cup.
