Description

Technical Field

[0001] The utility model relates to the technical field of toys, in particular to a toy doll grabbing mechanism. Background Art

[0002] Currently, some miniature claw machine games suitable for children to play at home have begun to be launched on the market. For example, the utility model patent application "CN218357308U" entitled "A Toy Claw Machine" discloses a toy claw machine comprising a main body, a connecting rod disposed within the main body and movably connected to the main body, a rotating bracket disposed within the rotating bracket, an adjustment motor disposed within the rotating bracket, a worm disposed at the output end of the adjustment motor, a contact gear disposed within the rotating bracket, the contact gear movably connected to the rotating bracket, and a threaded connection between the contact gear and the worm, a winding turntable and a transfer gear disposed within the rotating bracket, each movably connected to the rotating bracket, the winding turntable and the transfer gear intermeshing with each other, and the transfer gear intermeshing with the contact gear, the adjustment motor drives the worm to rotate, and then, through the layered engagement between the contact gear, the winding turntable, and the transfer gear, a rope connected to the clamping claw is wound around or loosened on the winding turntable, thereby achieving the raising and lowering of the clamping claw. Since the gripper is suspended by a rope, slight shaking is inevitable when the rotating bracket rotates or the gripper is raised or lowered, and the clamping force is small, which to a certain extent affects the accuracy and success rate of gripping the doll, resulting in poor doll grabbing effect. Utility Model Content

[0003] In view of the above-mentioned shortcomings, the purpose of the present invention is to provide a toy doll grabbing mechanism with reasonable structural design and good doll grabbing effect.

[0024] The rotating pillar 2 is provided with a vertical slide groove, and the outer drive bar 5 and the inner resistance bar 6 pass through the vertical slide groove, and the outer drive bar 5 can drive the inner resistance bar 6 to move up and down when it moves up and down. The damping device 4 is arranged on the rotating pillar 2 and presses on the inner resistance bar 6. Preferably, an inner slide groove 51 is provided along the long side of the outer drive bar 5, and the lower end of the inner slide groove 51 is narrowed and provided with a step 52. The inner resistance bar 6 is movably located in the inner slide groove 51 and is provided with a locking position 61 that matches the step 52. Preferably, the inner resistance bar 6 is provided with a damping bar 62 that extends out of the inner slide groove 51 to facilitate cooperation with the damping device 4. The damping device 4 includes a pressing piece 41 and a damping spring 42. The pressing piece 41 presses on one end of the damping spring 42, and the other end of the damping spring 42 presses on the damping bar 62, which can provide a stable damping effect.

[0025] The gripper 1 is arranged at the lower end of the inner resistance bar 6, and the lower end of the outer drive bar 5 is connected to the gripper 1, and drives the gripper 1 to open and close accordingly when performing a lifting movement. Specifically, the gripper 1 includes a left connecting frame 11, a right connecting frame 12, a left claw hand 13 and a right claw hand 14. The upper ends of the left claw hand 13 and the right claw hand 14 are hinged to the lower end of the outer drive bar 5, and the upper ends of the left connecting frame 11 and the right connecting frame 12 are hinged to the lower end of the inner resistance bar 6, and the lower ends are correspondingly hinged to the upper positions of the left claw hand 13 and the right claw hand 14.

[0026] The lifting drive device 3 is mounted on the rotating support 2 and is capable of driving the outer drive bar 5 to move up and down. Specifically, the lifting drive device 3 comprises a motor 31, an input gear 32, a gear set 33, and an output gear 34. The input gear 32 is mounted on the drive shaft of the motor 31 and drives the output gear 34 to rotate via the gear set 33. The outer drive bar 5 is provided with teeth 53 that mate with the output gear 34. The motor 31 drives the outer drive bar 5 up and down via the gear set 33, resulting in high transmission efficiency.

[0027] See also Figure 6The toy claw mechanism of the present invention also includes a rotary drive device 7 that can drive the rotating pillar 2 to rotate. The rotary drive device 7 can make the rotating pillar 2 rotate freely, thereby expanding the operating range of the gripper 1. Specifically, the rotary drive device 7 includes a rotary gear disc 71, a transmission shaft 72, a rotary drive tooth 73, a crown gear 74, a rotary linkage tooth 75 and a rotary power member 76. The rotary gear disc 71 is arranged at the lower end of the rotating pillar 2, and the rotary drive tooth 73 is arranged on the power shaft of the rotary power member 76. The crown gear 74 is arranged at one end of the transmission shaft 72 and meshes with the rotary drive tooth 73. The rotary linkage tooth 75 is arranged at the other end of the transmission shaft 72 and meshes with the rotary gear disc 71, thereby achieving smooth rotation of the rotating pillar 2. In this embodiment, the rotary power member 76 is preferably a manual crank. In other embodiments, the rotary power member 76 can also be an electric rotary motor to meet the needs of different users.

[0028] During play, the user can crank the hand crank to rotate the pivot 2, moving the gripper 1 to a position above the object to be gripped. Pressing the lowering button causes the lifting drive 3 to lower the outer drive bar 5. At this point, the damping device 4 presses against the inner resistance bar 6, temporarily immobilizing it. The outer drive bar 5 continues to descend, pushing the left and right grippers 13 and 14 toward each other. When the left and right grippers 13 and 14 open to a predetermined degree, the inner resistance bar 6, driven by the left and right coupling frames 11 and 12, simultaneously lowers to the desired position.

[0029] Pressing the raise button causes the lift drive 3 to raise and lower the outer drive bar 5. At this point, the damping device 4 presses against the inner resistance bar 6, temporarily immobilizing it. The outer drive bar 5 continues to rise, pushing the left and right grippers 13 and 14 toward each other to clamp the object. As the left and right grippers 13 and 14 grip the object, the step 52 and the latch 61 engage, synchronously raising the inner resistance bar 6 to the desired height. The manual crank is then operated to rotate the rotating support 2, moving the gripper 1 to a position above the drop port for delivery. This completes the catching process, a simple and convenient operation.

Therefore, the present invention is not limited to the specific embodiments described above. Any obvious improvements, substitutions, or modifications made by those skilled in the art based on the present invention fall within the scope of protection of the present invention. Furthermore, while certain specific terms are used in this specification, these terms are for convenience only and do not constitute any limitation to the present invention. Other toys using the same or similar structures are also within the scope of protection of the present invention.
