Description

Technical Field

[0001] This invention relates to the technical field of gift machines, and in particular to a gripper force adjustment structure for gift machines. Prior Technology

[0002] A claw machine (or game machine) is a machine containing multiple plush toys or prizes. Users control the movement of the claws using joysticks and buttons to grab the desired item. These claws are usually driven by electromagnets. According to the design in Chinese Patent No. I760767, the electromagnets control the opening and closing of the claws to achieve the purpose of grabbing.

[0003] However, using electromagnets to drive the grippers has certain limitations, as the clamping force is insufficient to handle dolls or gifts of varying weights and sizes, thus restricting their practical use due to environmental limitations. Therefore, existing gripper structures urgently need improvement to enhance their applicability and efficiency. Summary of the Invention

[0004] In view of the problems and deficiencies of the prior art, one of the objectives of the present invention is to provide a force adjustment structure for the gripper of a gift machine through structural innovation, so as to overcome the deficiencies of the prior art.

[0005] To achieve the above objectives, this invention proposes a gripper force adjustment structure for a gift machine, comprising a housing, a motor, a lifting mechanism, a connecting mechanism, multiple tension adjustment mechanisms, and a gripper mechanism. The lifting mechanism is connected in series with the motor and operates synchronously. One end of the connecting mechanism is connected in series with the lifting mechanism, and the other end extends to the outer periphery of the housing to provide a preset elastic tension. Each tension adjustment mechanism is connected in series with the connecting mechanism to selectively adjust the tension. The gripper mechanism is pivotally connected to the connecting mechanism and the housing. Through the above components, a preset tension is provided to cause the gripper mechanism to retract and expand. Simple Explanation of the Diagram

[0019] The aforementioned suspension frame 20 is housed within the cylindrical body 11 in conjunction with the housing 10, and includes a first plate 21 and a second plate 22 arranged symmetrically, and a plurality of suspension rods 23 connecting the first and second plates 21 and 22.

[0020] The first plate 21 is stacked on the top surface of the cylindrical body 11 and is disposed between the top cover 12 and the cylindrical body 11.

[0021] The motor 30 is mounted on the second plate 22, and the motor output shaft 31 of the motor 30 extends through the second plate 22.

[0022] The aforementioned lifting mechanism 40 is connected to the suspension frame 20 and connected in series with the motor 30, and includes a lifting screw 41, a lifting nut 42, a plurality of guide columns 43, and a lifting ring 45.

[0023] The lifting screw 41 is connected in series with the motor output shaft 31 and moves in tandem with it. In practice, the lifting screw 41 is selected from high-lead screws.

[0024] The lifting nut 42 is screwed onto the outer periphery of the lifting screw 41.

[0025] Each guide post 43 is connected at one end to the bottom cover 13 and at the other end to the suspension bracket 20.

[0026] The lifting ring 45 is assembled at the bottom of the lifting nut 42 and moves together with it. The lifting ring 45 further has a ring shaft hole 451, a plurality of ring holes 452, and a plurality of screw holes 453, which are formed by penetrating the top and bottom of the lifting ring 45 respectively, wherein the ring shaft hole 451 provides a mounting for the lifting nut 42.

[0027] The aforementioned annular holes 452 are formed by the top and bottom of the lifting ring 45 and are arranged along the contour of the lifting ring 45 at a preset interval, so that each guide post 43 can be moved and matched to extend through.

[0028] The aforementioned screw holes 453 are formed by the top and bottom of the lifting ring 45 and are arranged along the contour of the lifting ring 45 at a preset interval.

[0029] The aforementioned connecting mechanism 50 extends through the housing 10 (bottom cover 13) at one end and is connected in series with the lifting mechanism 40, including a plurality of connecting pipes 51 and a lifting plate 52.

[0030] Each connecting tube 51 has a tube wing 511 at one end and a movable through-hole 13 at the other end that matches the bottom cover through-hole 131. Each connecting tube 51 has a hollow tubular pre-defined outline.

[0031] The lifting plate 52 has a plurality of plate through holes 521, which are formed by the top and bottom of the lifting plate 52, providing for the connection pipes 51 to be inserted and assembled and move together with it.

[0032] The aforementioned tension adjustment mechanism 60 is matched with each connecting pipe 51. Each tension adjustment mechanism 60 includes a flexible hose spring 61, a screw post 62, and an adjusting screw post 63.

[0033] Each of the hose springs 61 extends into the matching connecting tube 51.

[0034] Each of the threaded posts 62 is threaded through the threaded holes 453 of the lifting ring 45 and then tightly threaded to one end of the matching flexible hose spring 61.

[0035] Each adjusting stud 63 is tightly screwed to one end of each matching flexible hose spring 61, thereby pressing against one end of each matching connecting pipe 51.

[0036] In practice, the adjusting stud 63 has a rod body 631 and a rod head 632 respectively located at both ends of the adjusting stud 63; wherein, the rod body 631 extends through one end of the connecting tube 51 and is tightly screwed to one end of the flexible hose spring 61. The rod head 632 abuts against the cross-section of one end of the connecting tube 51.

[0037] The aforementioned gripper mechanism 70 is connected to and moves in tandem with the lifting plate 52, and includes a three-pronged component 71, a plurality of grippers 72, and a plurality of gripper pivot arms 73.

[0038] The three-pronged component 71 has a preset outline and is assembled at the bottom of the lifting plate 52.

[0039] Each of the grippers 72 has one end pivotally connected to the three-pronged member 71, and the other end is a free end.

[0040] Each gripper pivot arm 73 is pivotally connected at one end to the housing 10 (cylinder body 11) and at the other end to the gripper 72 at a preset position.

[0041] Therefore, the above is an introduction to the components and assembly method of the gift machine gripper force adjustment structure of a preferred embodiment of the present invention. The operating characteristics of the embodiment of the present invention will be introduced below.

[0042] The tension of the adjusting screw 63 can be adjusted by changing the stretch of the hose spring 61 through the screw 62 or the adjusting screw 63. This design not only improves the flexibility of the gripper 72, but also better accommodates dolls or gifts of different weights and sizes, increasing the success rate of grasping.

[0043] In addition, when the gripper mechanism 70 is used for large-volume gifts, the grippers 72 can exert stronger gripping force through the stretching and adjustment effect of each hose spring 61.

[0044] The above description is merely a preferred embodiment of the present invention and is intended to clarify the features of the present invention. It is not intended to limit the scope of the embodiments of the present invention. Equivalent variations made by those skilled in the art based on the present invention, as well as changes well known to those skilled in the art, should still fall within the scope of the present invention.
