Gripper structure

Abstract

The invention discloses a gripper structure. The gripper structure comprises a body, a valve pipe, a clamping jaw and a vertical pipe, the valve pipe is arranged in the body, and the vertical pipe is pivoted to the clamping jaw which is pivoted to the bottom of the body. When the vertical pipe moves up and down, the clamping jaw is contracted inwards or expanded outwards, upper and lower ends of the valve pipe are wound by an upper coil section and a lower coil section respectively, the tail end of the upper coil section is connected with a starting end of the lower coil section, and a starting end of the upper coil section and the tail end of the lower coil section are connected with an external power source. The gripper structure further comprises a magnetic element which is arranged in the valve pipe in a vertically movable manner, and the magnetic element is connected with the vertical pipe. A magnetic pole at the top end of the magnetic element is opposite to that above the electrified upper coil section, a magnetic pole at the bottom end of the magnetic element is opposite to that above the electrified lower coil section, and the length of the magnetic element corresponds to a distance between the upper coil section and the lower coil section.

Description

technical field [0001] The invention relates to the field of game equipment, in particular to a claw structure. Background technique [0002] The object-grabbing game machine (or called a claw machine, a vending machine, etc.) is a kind of game machine that is widely loved by the public. [0003] The grasping claw of existing object grabbing game machine, such as figure 1 As shown, it includes a cylindrical body 10, a valve tube 11 is arranged inside the body 10, and a coil 12 is wound around the valve tube 11 to form a solenoid valve after being energized; the bottom of the body 10 is pivoted with a clip Claw 13, and this clamping claw 13 is pivotally connected with a valve rod 14, and this valve rod 14 is the metal bar member (such as: iron rod) that can be attracted by magnetic force, and this valve rod 14 extends in the valve tube 11; After the coil 12 of the valve tube 11 is energized, a magnetic force is generated, and the valve stem 4 is attracted by the magnetic fo...

AI Technical Summary

Problems solved by technology

[0004] Because the above-mentioned gripper must wind a large amount of coils outside the valve pipe 11, the valve stem 14 of the gripper can be moved under the action of the magnetic field generated after the coil is energized, and then a large number of winding coils not only waste resources, but also increase the manufacturing cost. It is not possible to replace the claws of different sizes, which is also very inconvenient in use
