[0048] This utility model proposes a clamp for a toy grabbing machine.

[0049] In this embodiment of the utility model, please refer to Figures 1 to 5 The gripper of the toy grabber includes a limiting sleeve 10, an adjusting component 20, and a clamping component 30.

[0050] The adjustment component 20 includes a first pivot plate 21 and at least two connecting rods 22 spaced apart along the outer periphery of the first pivot plate 21; the first pivot plate 21 has a first adjustment hole 211 and a fixing hole 212 that both pass through the first pivot plate 21 in the vertical direction, and the first adjustment hole 211 and the fixing hole 212 allow the bead chain to move up and down.

[0051] A clamping assembly 30 is movably connected to the adjusting assembly 20. The clamping assembly 30 includes a second pivot plate 31 located below the first pivot plate 21 and at least two clamping rods 32 spaced apart along the outer periphery of the second pivot plate 31. A second adjusting hole 311 is provided in the middle of the second pivot plate 31, extending through the second pivot plate 31 in a vertical direction, allowing the bead chain to move up and down. One end of the connecting rod 22 is movably connected to the first pivot plate 21, and the other end is movably connected to the clamping rod 32. One end of the clamping rod 32 is movably connected to the second pivot plate 31, and the ends of adjacent clamping rods 32 approach or separate to open or close the clamp.

[0052] The pivot structure includes a fixed rod 431 and a deformable part connected to each other, the fixed rod 431 and the deformable part being arranged axially; the fixed rod 431 and the deformable part passing through the connecting rod 22 and the first pivot plate 21, the deformable part being at the upper limit of the axial direction of the fixed rod 431 with respect to the connecting rod 22 or the first pivot plate 21; and / or, the fixed rod 431 and the deformable part passing through the connecting rod 22 and the clamping rod 32, the deformable part being at the upper limit of the axial direction of the fixed rod 431 with respect to the connecting rod 22 or the clamping rod 32; and / or, the fixed rod 431 and the deformable part passing through the clamping rod 32 and the second pivot plate 31, the deformable part being at the upper limit of the axial direction of the fixed rod 431 with respect to the clamping rod 32 or the second pivot plate 31.

[0053] In this embodiment, the gripper 100 of the grasping toy machine refers to the part of the grasping toy machine that can simulate the opening or closing of a hand to grasp dolls or toys.

[0054] The adjustment component 20 refers to the component in the gripper 100 of the grasping toy machine that can drive other parts to move to complete the opening or closing action. The adjustment component 20 includes a first pivot plate 21 and at least two connecting rods 22 spaced apart along the outer periphery of the first pivot plate 21; there can be two, three, four, etc., connecting rods 22. One end of the connecting rod 22 is movably connected to the first pivot plate 21, and the other end is movably connected to the connecting section. The gripper 100 of the grasping toy machine adjusts the height difference between the first pivot plate 21 and the second pivot plate 31, causing the connecting rods 22 to move relative to the first pivot plate 21 and the second pivot plate 31. Since the connecting rods 22 are movably connected to the clamping rods 32, the connecting rods 22 drive the clamping rods 32 to move, thereby causing the multiple clamping rods 32 to separate or move closer to each other to complete the simulated opening or closing action of a hand.

[0055] The clamping assembly 30 refers to the component in the clamp 100 of the grasping toy machine that directly performs the opening or closing action. The clamping assembly 30 includes a second pivot plate 31 located below the first pivot plate 21 and at least two clamping rods 32 spaced apart along the outer periphery of the second pivot plate 31. The number of clamping rods 32 corresponds to the number of connecting rods 22, and the number of clamping rods 32 can be two, three, four, etc.

[0056] The pivot structure is a key component for enabling the opening and closing of multiple clamping rods 32. The pivot structure includes a fixed rod 431 and a deformable portion that are interconnected, with the fixed rod 431 and the deformable portion arranged axially along the fixed rod 431. The fixed rod 431 serves as the main support of the pivot structure, providing fixation and connection. The deformable portion deforms when passing through the connecting rod 22 / first pivot plate 21 / second pivot plate 31 / clamping rod 32, allowing it to pass smoothly, and then returns to its original shape, reaching the upper limit of the fixed rod 431 along its axial direction. The specific shape of the deformable portion is not limited here.

[0057] Compared to pivotal structures that require fasteners such as nuts and bolts, the pivotal structure in this embodiment eliminates the need for cumbersome tightening operations during assembly. Simply insert the fixing rod 431 into the connecting rod 22 / first pivot plate 21 / second pivot plate 31 / clamping rod 32, and the deformable part will automatically engage with it. In contrast, pivotal structures using nuts and bolts require tools for disassembly and assembly, making the process more cumbersome, and the difficulty of disassembly may be increased due to rust or damage to the nuts and bolts.

[0058] Compared to a hook-type pivot structure, the pivot structure in this embodiment allows for more precise pivoting movements. A hook-type pivot structure may experience wobbling during pivoting due to a large gap between the hook and the pivot rod, affecting pivoting accuracy. In this embodiment, the insertion of the fixed rod 431 and the limiting position of the elastic buckle 432 ensure a stable relative position between the fixed rod 431 and the connecting rod 22 / first pivot plate 21 / second pivot plate 31 / clamping rod 32. This allows the pivoting movement to proceed along the designed path, reducing unnecessary deviations, improving pivoting accuracy, and consequently, increasing the accuracy and success rate of object grasping.

[0059] This invention utilizes the deformable feature of the deformable part to allow the installation of the pivot structure to be completed without the aid of external tools. Simultaneously, the insertion of the fixing rod 431 ensures stable relative positions between the fixing rod 431 and the connecting rod 22 / first pivot plate 21 / second pivot plate 31 / clamping rod 32, improving pivoting accuracy and thus enhancing the accuracy and success rate of the gripper in the toy-grabbing machine.

[0060] Furthermore, the pivot structure also includes two oppositely arranged lugs 41 and a pivot piece 42 sandwiched between the two lugs 41; both the lugs 41 and the pivot piece 42 are provided with through holes; the deformable part includes at least two elastic buckles 432 provided at one end of the fixing rod 431, and the plurality of elastic buckles 432 are arranged circumferentially along the axial direction of the fixing rod 431; the fixing rod 431 is inserted into the through hole, and the elastic buckles 432 are engaged with the lugs 41 in the axial direction of the fixing rod 431; one of the connecting rod 22 and the first pivot plate 21 is provided with two oppositely arranged lugs 41, and the other is provided with a pivot piece 42; and / or, one of the connecting rod 22 and the clamping rod 32 is provided with two oppositely arranged lugs 41, and the other is provided with a pivot piece 42; and / or, one of the clamping rod 32 and the second pivot plate 31 is provided with two oppositely arranged lugs 41, and the other is provided with a pivot piece 42.

[0061] In this embodiment, the elastic buckle 432 undergoes elastic deformation when passing through the through hole, allowing it to pass smoothly through the through hole. After passing through, it returns to its elastic deformation and engages with the lug 41. At this time, the fixing rod 431 is inserted into the through hole. In this way, the installation of the pivot structure can be completed without the aid of external tools.

[0062] In one embodiment, the fixing rod 431 has a cavity. During injection molding, the plastic material shrinks during cooling, a phenomenon known as shrinkage. Shrinkage can lead to dimensional deviations, surface depressions, and insufficient strength in the molded parts. The cavity design of the fixing rod 431 effectively alleviates the shrinkage problem, allowing the fixing rod 431 to maintain a smooth outer surface, thus enabling it to rotate flexibly within the through-hole and improving pivoting accuracy. Simultaneously, the cavity design significantly reduces the weight of the fixing rod 431. In the pivoting structure, the lighter fixing rod 431 reduces motion inertia, making the entire pivoting structure more flexible and responsive during movement. This flexibility helps improve the motion accuracy of the pivoting structure, especially in devices like the grippers of grasping toys that require rapid adjustments and frequent movements.

[0063] In one embodiment, the end of the retaining rod 431 furthest from the resilient latch 432 extends axially beyond the surface of the lug 41. When the end of the retaining rod 431 extends beyond the surface of the lug 41, it provides the user with a wider gripping space. This design allows the user to more easily grip the retaining rod 431 with their fingers without being hindered by the lug 41. The extended portion allows the user to apply force more easily during operation, enabling more precise control of force and direction, whether rotating, pulling, or pushing.

[0064] In one embodiment, the gripper of the grasping toy machine further includes a limiting sleeve 10, which has an opening 11 at one end in its axial direction and an end wall 12 at the other end; the end wall 12 is provided with a first channel 125, and the side wall of the limiting sleeve 10 is provided with a second channel 13 communicating with the first channel 125; the inner wall of the first channel 125 is provided with a detachment stop 122 protruding in the middle of its extending direction to prevent the bead chain from coming out of the limiting sleeve 10;

[0065] A limiting sleeve 10 is provided below the fixing hole 212. The diameter of the fixing hole 212 is larger than the maximum width of the first channel 125, and the limiting sleeve 10 is engaged with the first pivot plate 21; and / or,

[0066] Below the second adjustment hole 311, there is another limiting sleeve 10. The diameter of the second adjustment hole 311 is larger than the maximum width of the first channel 125. The limiting sleeve 10 is engaged with the second pivot plate 31.

[0067] The limiting sleeve 10 is used to restrict the position of the bead chain to improve the gripping success rate of the clamp. In some embodiments, the limiting sleeve 10 is only provided below the fixing hole 212 or the second adjusting hole 311; in other embodiments, the limiting sleeve 10 is provided below both the fixing hole 212 and the second adjusting hole 311. The opening 11, the second channel 13, and the first channel 125 in the limiting sleeve 10 provide an installation path for the bead chain. The bead chain includes a plurality of beads and a chain cord that strings the beads together. The end wall 12 is used to abut against a bead at one end of the bead chain, preventing the bead from coming off the limiting sleeve 10. The anti-detachment member 122 can prevent the bead chain from coming off the limiting sleeve 10 along the first channel 125 after installation. The anti-detachment member 122 can be one or more, and the specific number and shape are not limited here.

[0068] During installation, first, place the bead in the opening 11 at one end of the limiting sleeve 10, and align the chain between adjacent beads with the second channel 13. Next, move the chain along the second channel 13 until the bead abuts against the end wall 12. Then, move the bead along the first channel 125 until the chain passes through the anti-detachment member 122. Immediately afterward, place the limiting sleeve 10 below the fixing hole 212 or the second adjusting hole 311. In this way, the hole wall of the fixing hole 212 or the second adjusting hole 311 will block the first channel 125, so that the bead chain will not come out of the first channel 125 even if it is shaken violently. The engagement between the limiting sleeve 10 and the first pivot plate 21 or the second pivot plate 31 keeps the hole wall of the fixing hole 212 or the second adjusting hole 311 blocking the first channel 125 during use, so that the bead chain cannot come out of the limiting sleeve 10 for a long time.

[0069] To ensure the bead chain can pass smoothly through the fixing hole 212 or the second adjustment hole 311 during installation, current claw machine clawing machines typically have sufficiently large diameters in these holes. This means the bead chain has a relatively wide range of motion. However, when the gripper tends to tilt or tilts, the offset of the bead chain passing through the fixing hole 212 or the second adjustment hole 311 can cause or exacerbate the tilt, resulting in a low success rate for the gripper. Furthermore, claw machine clawing machines frequently experience bead chains tangling in the fixing hole 212 and the first adjustment hole 211 during use. To address this, players often operate the controller to violently shake the gripper, attempting to untangle the tangled chains. However, violent shaking may cause the bead chain to disengage from the first pivot plate 21 or the second pivot plate 31.

[0070] This embodiment addresses the problem of excessively large diameters in the fixing hole 212 or the second adjustment hole 311, which can lead to easy tilting of the clamp and low success rate in grasping objects. The diameter of the fixing hole 212 or the second adjustment hole 311 is larger than the maximum width of the first channel 125; that is, the maximum width of the first channel 125 is smaller than the diameter of the fixing hole 212 or the second adjustment hole 311. When the bead chain is installed in the limiting sleeve 10, the swing amplitude of the bead chain is limited by the width of the first channel 125. This restricts the swing range of the bead chain, making the clamp less prone to imbalance and thus improving the success rate of grasping objects. Compared to reducing the diameter of the fixing hole 212 or the second adjustment hole 311 to limit the swing range of the bead chain, this embodiment makes installation more convenient and efficient. Specifically, one end of the bead chain is connected to the drive device, and the other end first passes through the fixing hole 212 or the second adjustment hole 311, and then is installed on the limiting sleeve 10; next, the limiting sleeve 10 is engaged with the first pivot plate 21 or the second pivot plate 31. In comparison, reducing the diameter of the fixing hole 212 or the second adjustment hole 311 significantly increases the difficulty of the bead chain passing through the fixing hole 212 or the second adjustment hole 311, resulting in a significant decrease in assembly efficiency.

[0071] In addition, the present invention uses the end wall 12 and the limiting sleeve 10 to engage with the first pivot plate 21 or the second pivot plate 31 to keep the relative position of one end of the bead chain with the first pivot plate 21 or the second pivot plate 31 stable, so as to prevent the bead chain from detaching from the first pivot plate 21 or the second pivot plate 31 when subjected to external force impact.

[0072] Further, please refer to Figure 2 , Figure 4 , Figure 7 as well as Figure 8The anti-detachment component 122 includes two opposing limiting protrusions 1221, which are spaced apart to form a slit 123; the inner wall surfaces of the limiting protrusions 1221 and the first channel 125 enclose a mounting hole 121 adapted to the bead chain; the width of the slit 123 is smaller than the diameter of the mounting hole 121 and the slit 123 connects the mounting hole 121 and the second channel 13.

[0073] In this embodiment, the inner wall of the limiting protrusion 1221 and the first channel 125 surrounds to form an installation hole 121 that is adapted to the bead chain, so that after the bead chain is installed, the bead at one end of the bead chain abuts against the inner surface of the end wall 12, preventing the bead chain from coming off the limiting sleeve 10 upwards; at the same time, it allows the chain to swing in the installation hole 121.

[0074] The slit 123 connects the mounting hole 121 and the second channel 13, providing an installation path for the bead chain from the second channel 13 to the mounting hole 121. The width of the slit 123 is smaller than the diameter of the mounting hole 121, allowing the bead chain to move within the mounting hole 121 under normal circumstances, but making it difficult for it to detach from the slit 123. This effectively prevents the bead chain from accidentally detaching from the limiting sleeve 10, further enhancing the stability and reliability of the bead chain within the limiting sleeve 10. This allows for more precise control of the movement of the bead chain, enabling more accurate gripping of the object and improving the success rate of object grasping.

[0075] In one embodiment, please refer to Figure 4 and Figure 8 The inner surface of the end wall 12 is provided with a recess 124, and the first channel 125 is provided in the recess 124.

[0076] Compared to the case where the inner surface of the end wall 12 is flat, in this embodiment, the inner surface of the end wall 12 is provided with a recess 124 to effectively buffer the impact force generated when the bead chain moves, reducing frictional loss between the bead chain and the inner surface of the end wall 12. At the same time, the shape and size of the recess 124 can play a certain positioning role for the beads, making the position of the bead chain in the first channel 125 more stable, reducing the offset of the bead chain in the length direction of the first channel 125, and thus avoiding excessive offset of the grasping toy machine, which would lead to a decrease in the success rate of grasping objects.

[0077] In one embodiment, please refer to Figure 7 and Figure 8 The outer side wall of the limiting sleeve 10 is provided with a first engaging part 14, and the first pivot plate 21 and / or the second pivot plate 31 are provided with a second engaging part that is adapted to the engaging part; one of the first engaging part 14 and the second engaging part is a protrusion and the other is a groove.

[0078] In this embodiment, the first engaging part 14 and the second engaging part enable a stable connection between the limiting sleeve 10 and the first pivot plate 21 or the second pivot plate 31, which improves the stability of the entire clamp, reduces the risk of clamp performance degradation or failure due to loose parts or weak connections, and ensures the reliability of the toy grabber during long-term use.

The second stop protrusion 321 is arranged relative to the first stop protrusion 221 near the central axis of the second pivot plate 31. The second stop protrusion 321 is located on the movement path of the first stop protrusion 221, so that the first stop protrusion 221 can rotate to abut against the second stop protrusion 321.

[0082] In this embodiment, the rotatable connection between the connecting rod 22 and the clamping rod 32 allows the clamping rod 32 to rotate relative to the connecting rod 22, which is the basis for realizing the opening and closing action of the clamp. Through the cooperation of the first stop protrusion 221 and the second stop protrusion 321, the relative rotation angle between the connecting rod 22 and the clamping rod 32 can be precisely controlled, thereby precisely controlling the opening and closing degree of the clamp. When the toy grasping machine is working, when the first stop protrusion 221 abuts against the second stop protrusion 321, the limit position of the clamp opening and closing is reached, avoiding structural damage or ineffective object grasping caused by excessive opening and closing, and improving the operating accuracy and reliability of the clamp.

[0083] In one embodiment, the ends of the gripping rods 32 are provided with teeth protruding towards the central axis of the second pivot plate 31. Thus, when adjacent gripping rods 32 approach each other, the teeth on the multiple gripping rods 32 can engage with each other to form a tighter gripping structure, which helps to firmly grasp the object. For objects with smooth surfaces or irregular shapes, the teeth can provide additional friction and gripping force, preventing the object from slipping during gripping, thereby reducing gripping failures and improving the success rate of gripping.

[0084] In one embodiment, please refer to Figure 1 and Figure 2 The grasping toy machine includes a tray 50 detachably mounted to the end of the gripping rod 32; the tray 50 includes a first gripping surface 52 disposed toward the central axis of the second pivot plate 31 and a first lifting surface 51 disposed opposite to the first gripping surface 52; the first lifting surface 51 is in contact with the plane of the gripping rod 32 near the central axis of the second pivot plate 31; the tray 50 also includes a barrier 53 surrounding and connected to the edge of the gripping surface.

[0085] In this embodiment, the tray 50 is detachably mounted on the end of the clamping rod 32, providing the possibility of functional expansion for the gripper of the grasping toy machine. When different types of objects need to be grasped, different trays 50 can be replaced according to actual needs, improving the adaptability and flexibility of the grasping toy machine. For example, for larger, thinner, or specially shaped objects, by replacing the appropriate tray 50, the grasping task can be completed better, and the success rate of grasping can be improved.

[0086] The first clamping surface 52 can directly contact the object. By adjusting its shape and material, it can better adapt to different object surfaces and provide a better gripping effect. The first lifting surface 51 is attached to the plane of the clamping rod 32 near the central axis of the second pivot plate 31. It provides a base for the installation and support of the pallet 50, ensuring that the pallet 50 can be stably connected to the clamping rod 32 during use.

[0087] The barrier 53 is connected around the edge of the clamping surface to prevent objects from slipping off the side. When gripping small or easily rolling objects, the barrier 53 can confine the object within the area of ​​the pallet 50, preventing the object from rolling off the side during the gripping process, thus further enhancing the gripping function of the pallet 50.

[0088] In one embodiment, please refer to Figure 2 The grasping toy machine includes a tray 50 detachably mounted on the end of the gripping rod 32; the tray 50 includes a first clamping surface 52 disposed toward the central axis of the second pivot plate 31 and a first lifting surface 51 disposed opposite to the first clamping surface 52; the first lifting surface 51 is in contact with the plane of the gripping rod 32 near the central axis of the second pivot plate 31; the first lifting surface 51 is provided with a limiting buckle 511 and an assembly groove 512; the limiting buckle 511 and the assembly groove 512 are distributed along the extension direction of the gripping rod 32; the rod body of the gripping rod 32 is engaged with the limiting buckle 511, and the end of the gripping rod 32 is inserted into the assembly groove 512.

[0089] In this embodiment, the limiting buckle 511 and the assembly groove 512 are distributed along the extension direction of the clamping rod 32, so that the pallet 50 can be evenly stressed in the extension direction of the clamping rod 32, avoiding the pallet 50 from loosening or falling off due to stress during the gripping process, thus ensuring the safety and reliability of the gripping operation. At the same time, the assembly groove 512 allows the end of the clamping rod 32 to be inserted, which not only further ensures the correct installation position of the pallet 50, but also makes the connection between the pallet 50 and the clamping rod 32 tighter and more secure, preventing the pallet 50 from falling off the clamping rod 32 when under heavy load. Furthermore, the peripheral wall of the assembly groove 512 can also prevent the end of the pallet 50 from tilting due to uneven stress.

[0090] In one embodiment, please refer to Figure 1 and Figure 2 The grabbing toy machine includes a tray 50 detachably mounted to the end of the gripping rod 32, the end of the tray 50 having a first tooth 54 protruding toward the central axis of the second pivot plate 31.

[0091] In this embodiment, when adjacent gripping rods 32 approach each other, the support plates 50 on the gripping rods 32 also approach each other. The first teeth 54 on the support plates 50 can cooperate to form a tighter gripping structure, which helps to firmly grasp the object. For some objects with smooth surfaces or irregular shapes, the first teeth 54 can provide additional friction and gripping force to prevent the object from slipping during the gripping process, thereby reducing the occurrence of gripping failures and improving the success rate of gripping.

[0092] In one embodiment, please refer to Figure 1The clamping rod 32 has a through hole 323 in its middle section, and the diameter of the through hole 323 extends along the extension direction of the clamping rod 32. In this way, during transportation, nylon cable ties, ropes, etc. can be passed through the through holes 323 on each clamping rod 32 to bring the clamping rods 32 closer together and fix them, thereby preventing the clamping rods 32 from being damaged by collision due to bumps.
