Abstract
Description
Technical Field
[0001] This utility model relates to the field of game machine technology, and in particular to a mechanical hook hand device. Background Technology
[0002] Typically, after a coin is inserted into a prize machine, a robotic arm moves and grabs a prize. One type of prize machine features a mechanical hook. When the hook moves close to the prize, the motor's output connects to the hook, causing it to rotate and pass through the prize's opening, thus hooking the prize. However, if the angle between the hook and the prize's opening is not aligned, or if the prize is heavy, the motor continues to rotate, causing the hook to slam into the prize and transmitting the impact to the motor. This can easily damage the motor and hinders cost savings. Utility Model Content

[0005] As an example of this application, the hook assembly further includes a first rotating wheel and a second rotating wheel that are rotatably connected to the fixed frame, respectively. The first axis coincides with the rotation center of the first rotating wheel, and the second axis coincides with the rotation center of the second rotating wheel. The driving mechanism is used to drive the first rotating wheel to rotate. The end of the first connecting rod away from the linkage mechanism is fixedly connected to the first rotating wheel. The hook is fixedly connected to the second rotating wheel, and the end of the second connecting rod away from the linkage mechanism is fixedly connected to the second rotating wheel.
[0006] As an example of this application, the linkage mechanism is provided with a movable hole, the elastic element is located in the movable hole, the first connecting rod passes through the movable hole, and the two ends of the elastic element abut against the inner wall of the movable hole and the first connecting rod, respectively.
[0007] As an example of this application, the linkage mechanism includes a first plate and a second plate that are detachably connected. The first plate has a first hole, and the second plate has a second hole. The first hole and the second hole communicate with each other to form the movable hole.
[0008] As an example of this application, the inner wall of the first hole is provided with a first blocking portion extending toward the elastic member, the first blocking portion being located on the side of the first plate away from the second plate, and the inner wall of the second hole is provided with a second blocking portion extending toward the elastic member, the second blocking portion being located on the side of the second plate away from the first plate, the first blocking portion and the second blocking portion being used to prevent the elastic member from disengaging from the movable hole.
[0009] As an example of this application, the linkage mechanism has a mounting hole at the end away from the first connecting rod, and the second connecting rod passes through the mounting hole and is rotatably connected to the linkage mechanism.
[0010] As an example of this application, the moving unit includes a horizontal moving component and a vertical moving component. The mounting frame has a first guide rail. The horizontal moving component is slidably connected to the first guide rail. The vertical moving component is connected to the horizontal moving component. The fixed frame is connected to the vertical moving component. The vertical moving component is used to drive the fixed frame to move in the up-down direction.
[0011] As an example of this application, it also includes the first transmission mechanism, the horizontal moving component includes a first frame and a roller, the roller is rotatably connected to the first frame, the roller is located in the first guide rail and the roller is capable of moving along the first guide rail, and the first transmission mechanism is used to drive the horizontal moving component to move.
[0012] As an example of this application, the first transmission mechanism includes a first conveyor belt and first transmission teeth that mesh with the first conveyor belt and drive it to rotate.

[0014] The mechanical hook device described in this utility model has at least the following beneficial effects: Since the fixed frame of the hooking component is connected to the moving unit, the moving unit drives the hooking component to move closer to the gift. When the hooking component moves to a preset position, the drive mechanism drives the first connecting rod to rotate around the first axis. Since one end of the elastic element is connected to the inside of the linkage mechanism, and the other end is connected to the first connecting rod, under the elastic action of the elastic element, the first connecting rod rotates, driving the linkage mechanism to move, which in turn drives the second connecting rod to rotate around the second axis, causing the hook to rotate around the second axis and hook the gift. If the angle between the hook and the gift is incorrect during the hook's rotation, causing the hook to collide with the gift and the gift to obstruct the hook's rotation, the drive mechanism continues to drive the first connecting rod to rotate. The first connecting rod compresses the elastic element, causing the compressed elastic element to absorb the impact, preventing the hook from colliding with the gift and transmitting the instantaneous impact to the drive mechanism. This also reduces the risk of damage to the drive mechanism due to the output end failing to move, thus saving maintenance costs. Attached Figure Description

[0046] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.
[0047] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides a mechanical hook device, including a mounting frame 100, a moving unit, and a hooking assembly 400. The moving unit is movable relative to the mounting frame 100. The hooking assembly 400 includes a fixed frame 410, a hook 420, a first connecting rod 430, a drive mechanism 450, and a linkage mechanism 500. The fixed frame 410 is connected to the moving unit, enabling the moving unit to drive the hooking assembly 400 to move, thereby allowing the hook 420 of the hooking assembly 400 to move closer to a gift 900. The drive mechanism 450 is connected to the first connecting rod 430, and the drive mechanism 450 drives the first connecting rod 430 to rotate around a first axis 401. The hook 420 is rotatably connected to the fixed frame 410, enabling the hook 420 to rotate around a second axis 402, thereby allowing the hook 420 to hook the gift 900. The first axis 401 and the second axis 402 are parallel. The hook 420 is provided with a second connecting rod 460 offset from the second axis 402, and the second connecting rod 460 can rotate around the second axis 402. A linkage mechanism 500 is disposed between the first connecting rod 430 and the second connecting rod 460, so that the first connecting rod 430 can drive the second connecting rod 460 to rotate via the linkage mechanism 500, thereby driving the hook 420 to rotate. The linkage mechanism is rotatably connected to the second connecting rod 460. An elastic element 440 is provided within the linkage mechanism 500. One end of the elastic element 440 away from the second connecting rod 460 abuts against the first connecting rod 430, and the other end of the elastic element 440 is connected to the interior of the linkage mechanism 500, allowing the first connecting rod 430 to compress the elastic element 440.
[0048] It is understood that the embodiments of this utility model provide a mechanical hook device for application in gift machines.
[0049] Reference Figure 9 and Figure 10In some embodiments of this utility model, when the moving unit drives the hook assembly 400 to move to a preset position, the driving mechanism 450 drives the first connecting rod 430 to rotate around the first axis 401. Since the two ends of the elastic member 440 abut against the inside of the first connecting rod 430 and the linkage mechanism 500 respectively, under the elastic force of the elastic member 440, the rotating first connecting rod 430 drives the linkage mechanism 500 to move, drives the second connecting rod 460 to rotate around the second axis 402, and then drives the hook 420 to rotate around the second axis 402 and hook the gift 900. If the angle between the hook 420 and the gift 900 is incorrect during rotation, causing the hook 420 to collide with the gift 900 and generate a momentary impact, and the gift 900 obstructs the rotation of the hook 420, the second connecting rod 460 will stop rotating. Since the second connecting rod 460 is rotatably connected to the linkage mechanism 500, the drive mechanism 450 keeps driving the first connecting rod 430 to rotate, causing the linkage mechanism 500 to swing around the second connecting rod 460. The rotating first connecting rod 430 compresses the elastic element 440 to absorb the impact, preventing the hook 420 from colliding with the gift 900 and transmitting the momentary impact to the drive mechanism 450, thus reducing the risk of damage to the drive mechanism 450 due to the momentary impact. Simultaneously, because the drive mechanism 450 can keep driving the first connecting rod 430 to rotate, the risk of damage to the drive mechanism 450 due to the output end of the drive mechanism 450 being unable to move is reduced, thus saving maintenance costs.
[0050] It is understood that the drive mechanism 450 can be a motor and a mechanical component connected to the motor output, or it can be other drive devices and mechanical components connected to them, enabling the drive mechanism 450 to drive the first connecting rod 430 to rotate. The specific structure and implementation of the drive mechanism 450 can be selected according to the actual application, and this application does not limit it.
[0051] It is understood that the elastic element 440 can be a spring, or a bellows, rubber elastic element 440, etc., and can be selected according to the actual application. This application does not limit it here.
[0052] Reference Figure 4 and Figure 5In some embodiments of this utility model, the hook assembly 400 further includes a first rotating wheel 470 and a second rotating wheel 480. The first rotating wheel 470 is rotatably connected to the fixed frame 410, and the first axis 401 coincides with the rotation center of the first rotating wheel 470. The end of the first connecting rod 430 away from the linkage mechanism 500 is fixedly connected to the first rotating wheel 470, and the first connecting rod 430 is offset from the first axis 401. The driving mechanism 450 is used to drive the first rotating wheel 470 to rotate, so that the first rotating wheel 470 drives the first connecting rod 430 to rotate around the first axis 401. The second rotating wheel 480 is rotatably connected to the fixed frame 410, and the second axis 402 coincides with the rotation center of the second rotating wheel 480. The end of the second connecting rod 460 away from the linkage mechanism 500 is fixedly connected to the second rotating wheel 480, and the second connecting rod 460 is offset from the second axis 402, so that the movement of the linkage mechanism 500 can drive the second connecting rod 460 to rotate around the second axis 402, thereby causing the second rotating wheel 480 to rotate. The hook 420 is fixedly connected to the second rotating wheel 480, so that the rotating second rotating wheel 480 can drive the hook 420 to rotate and hook the gift 900.
[0053] Reference Figure 3 and Figure 4 In some embodiments of this utility model, the linkage mechanism 500 is provided with a movable hole 501, an elastic element 440 is located inside the movable hole 501, and a first connecting rod 430 passes through the movable hole 501. The two ends of the elastic element 440 abut against the inner wall of the movable hole 501 and the first connecting rod 430, respectively, so that the first connecting rod 430 can compress the elastic element 440. When the first connecting rod 430 compresses the elastic element 440, the first connecting rod 430 moves along the extending direction of the movable hole 501. When the driving mechanism 450 drives the first connecting rod 430 to rotate around the first axis 401, since the two ends of the elastic element 440 abut against the first connecting rod 430 and the inner wall of the movable hole 501, under the elastic force of the elastic element 440, the first connecting rod 430 can drive the linkage mechanism 500 to move, thereby enabling the rotating first connecting rod 430 to drive the second connecting rod 460 to rotate, and driving the hook 420 to rotate and hook the gift 900.
[0054] Reference Figure 6In some embodiments of this utility model, the first connecting rod 430 includes a first extension section 431 and a first insertion section 432 connected in sequence. One end of the first extension section 431 is fixedly connected to the first rotating wheel 470, and the other end of the first extension section 431 is connected to the first insertion section 432. The first insertion section 432 passes through the movable hole 501 and abuts against the elastic member 440 so that the first insertion section 432 can compress the elastic member 440. The inner diameter of the first extension section 431 is larger than the inner diameter of the first insertion section 432. The end face of the first extension section 431 contacts the linkage mechanism 500. The end of the first insertion section 432 away from the first extension section 431 is detachably connected to the first card 433. The first card 433 contacts the linkage mechanism 500, so that the first insertion section 432 is inserted into the movable hole 501. The linkage mechanism 500 is located between the first card 433 and the first extension section 431, so that the first card 433 and the first extension section 431 prevent the first insertion section 432 from disengaging from the movable hole 501, ensuring the connection between the first connecting rod 430 and the connecting mechanism, thereby ensuring the reliability of the mechanical hook device proposed in this application.
[0055] Reference Figure 6 In some embodiments of this utility model, a first nylon sleeve 434 is provided on the outer peripheral wall of the first insertion segment 432. The outer peripheral wall of the first nylon sleeve 434 abuts against the elastic member 440, which reduces the risk of friction damage between the first insertion segment 432 and the elastic member 440, reduces the risk of friction damage between the first insertion segment 432 and the inner wall of the movable hole 501 of the linkage mechanism 500, and improves the service life of the first connecting rod 430.
[0056] Reference Figure 6 and Figure 7 In some embodiments of this utility model, the linkage mechanism 500 includes a first plate 510 and a second plate 520 that are detachably connected. The first plate 510 is provided with a first hole 511, and the second plate 520 is provided with a second hole 521. The first hole 511 and the second hole 521 communicate with each other to form a movable hole 501, and the elastic member 440 is located in the movable hole 501.
[0057] Reference Figure 8 In some embodiments of this utility model, the inner wall of the first hole 511 is provided with a first blocking portion 512 extending toward the elastic member 440, and the first blocking portion 512 is located on the side of the first plate 510 away from the second plate 520. The inner wall of the second hole 521 is provided with a second blocking portion 522 extending toward the elastic member 440, and the second blocking portion 522 is located on the side of the second plate 520 away from the first plate 510. The first blocking portion 512 and the second blocking portion 522 are used to prevent the elastic member 440 from disengaging from the movable hole 501, ensuring that the elastic member 440 is located in the movable hole 501, thereby ensuring that both ends of the elastic member 440 abut against the inner wall of the movable hole 501 and the first connecting rod 430.
[0058] It is understood that in some embodiments of this utility model, since the first plate 510 and the second plate 520 are detachably connected, when installing the elastic member 440, the elastic member 440 is placed between the first hole 511 of the first plate 510 and the second hole 521 of the second plate 520. Since the first plate 510 is provided with a first blocking part 512 and the second plate 520 is provided with a second blocking part 522, the elastic member 440 is held in the first hole 511 and the second hole 521. The first plate 510 is connected to the second plate 520, so that the elastic member 440 is installed on the linkage mechanism 500, and the elastic member 440 can be installed and removed from the linkage mechanism 500 independently, which facilitates the installation and removal efficiency of the elastic member 440.
[0059] Reference Figure 6 and Figure 7 In some embodiments of this utility model, the linkage mechanism 500 further includes a connecting plate 530. The connecting plate 530 has a first connecting hole 513 on a first plate body 510 and a second connecting hole 523 on a second plate body 520. The connecting plate 530 also includes a connecting tube 540, which is inserted into the first connecting hole 513 and the second connecting hole 523. A screw is inserted into the connecting tube 540, and the screw is threadedly connected to the inner wall of the connecting tube 540 to fix the first plate body 510, the second plate body 520, and the connecting rod, thereby achieving a detachable connection between the first plate body 510 and the second plate body 520.
[0060] It is understood that in some embodiments of this utility model, the first plate 510 and the second plate 520 are made of nylon. Nylon has a smooth surface and a low coefficient of friction, reducing frictional wear between the elastic element 440 and the first plate 510 and the second plate 520, and also reducing frictional wear between the first connecting rod and the first plate 510 and the second plate 520. A connecting tube 540 is inserted into the first connecting hole 513 and the second connecting hole 523, and the inner wall of the connecting tube 540 is threaded to connect with a screw, thus fixing the first plate 510, the second plate 520, and the connecting rod. This avoids the problem of difficulty in fixing the first plate 510 and the second plate 520 due to their nylon material, facilitating the fixing of the first plate 510 and the second plate 520, and reducing assembly difficulty.
[0061] Reference Figure 3 and Figure 4In some embodiments of this utility model, the end of the linkage mechanism 500 away from the first connecting rod 430 is provided with a mounting hole 502. The second connecting rod 460 passes through the mounting hole 502 and is rotatably connected to the linkage mechanism 500, so that the movement of the linkage mechanism 500 can drive the second connecting rod 460 to rotate around the second axis 402. Since the second connecting rod 460 is rotatably connected to the linkage mechanism 500, when the gift 900 obstructs the rotation of the hook 420 and the second connecting rod 460, the linkage mechanism 500 can swing around the second connecting rod 460.
[0062] Reference Figure 7 In some embodiments of this utility model, the first plate 510 and the second plate 520 are respectively provided with mounting holes 502, and the mounting holes 502 of the first plate 510 and the mounting holes 502 of the second plate 520 are connected, and the second connecting rod 460 is inserted into the mounting holes 502 of the first plate 510 and the mounting holes 502 of the second plate 520.
[0063] Reference Figure 5 In some embodiments of this utility model, the second connecting rod 460 includes a second extension section 461 and a second insertion section 462 connected in sequence. One end of the second extension section 461 is fixedly connected to the second rotating wheel 480, and the other end of the second extension section 461 is connected to the second insertion section 462. The second insertion section 462 is inserted into the mounting hole 502 and rotatably connected to the linkage mechanism 500. The inner diameter of the second extension 461 is larger than the inner diameter of the mounting hole 502, so that the end face of the second extension 461 contacts the linkage mechanism 500. The end of the second insertion section 462 away from the second extension 461 is detachably connected to the second card 463. The second card 463 contacts the linkage mechanism 500. The linkage mechanism 500 is located between the second extension 461 and the second card 463, so that the second extension 461 and the second card 463 are used to prevent the second insertion section 462 from disengaging from the mounting hole 502, ensuring the connection between the second connecting rod 460 and the linkage mechanism 500, ensuring that the linkage mechanism 500 can drive the rotation of the second connecting rod 460, thereby ensuring the reliability of the mechanical hook device proposed in this application.
[0064] Reference Figure 5 In some embodiments of this utility model, a second nylon sleeve 464 is sleeved on the outer peripheral wall of the second plug segment 462, and the outer peripheral wall of the second nylon sleeve 464 is inserted into the mounting hole 502, which reduces the risk of friction damage between the second plug segment 462 and the inner wall of the mounting hole 502, and improves the service life of the second connecting rod 460 and the linkage mechanism 500.
[0065] Reference Figure 2 and Figure 11In some embodiments of this utility model, the moving unit includes a horizontal moving component 200 and a vertical moving component 300. The mounting bracket 100 has a first guide rail 101. The horizontal moving component 200 is slidably connected to the first guide rail 101, allowing the horizontal moving component 200 to move along the extension direction of the first guide rail 101. The vertical moving component 300 is connected to the horizontal moving component 200, and the fixing bracket 410 is connected to the vertical moving component 300, allowing the horizontal moving component 200 to drive the vertical moving component 300 to move, thereby driving the hook component 400 to move along the extension direction of the first guide rail 101, and thus causing the hook 420 to move closer to the gift 900 in the extension direction of the first guide rail 101. Since the vertical moving component 300 is used to drive the fixing bracket 410 to move in the vertical direction, the vertical moving component 300 can drive the hook 420 of the hook component 400 to move in the vertical direction, thereby causing the hook 420 to move closer to the gift 900 in the vertical direction.
[0066] Reference Figure 2 and Figure 12 In some embodiments of this utility model, the horizontal moving component 200 includes a first frame 210 and a roller 220. The roller 220 is rotatably connected to the first frame 210 and is located within the first guide rail 101, so that the first frame 210 is suspended from the first guide rail 101, and the roller 220 can move along the first guide rail 101. Because the roller 220 can move along the first guide rail 101, the horizontal moving component 200 can be slidably connected to the first guide rail 101. The movement of the roller 220 along the first guide rail 101 reduces the friction between the horizontal moving component 200 and the first guide rail 101. The mechanical hook device proposed in this application also includes a first transmission mechanism 600, which is used to drive the horizontal moving component 200 to move.
[0067] Reference Figure 12 and Figure 13In some embodiments of this utility model, the first transmission mechanism 600 includes a first conveyor belt 610 and first transmission teeth 620 meshing with the first conveyor belt 610. The first transmission teeth 620 are used to drive the first conveyor belt 610 to rotate. Two sets of first transmission teeth 620 are located at both ends of the first tooth chain, and the first transmission teeth 620 are rotatably connected to the mounting frame 100. The first conveyor belt 610 is arranged along the extension direction of the first guide rail 101. Since the two sets of first transmission teeth 620 are rotatably connected to the mounting frame 100, the rotating first transmission teeth 620 can drive the first conveyor belt 610 to rotate. The horizontal moving assembly 200 also includes a first moving part 230, which is fixedly connected to the first frame 210. The first moving part 230 has a first tooth 231 meshing with the first conveyor belt 610, so that the rotating first conveyor belt 610 can drive the movement of the first moving part 230, thereby driving the first frame 210 to move, realizing that the first transmission mechanism 600 drives the horizontal moving assembly 200 to move. Because of the meshing of the first tooth 231 of the first conveyor belt 610 and the first moving part 230, the risk of slippage and wear of the horizontal moving component 200 relative to the first conveyor belt 610 is reduced, the risk of loss of movement steps of the horizontal moving component 200 is reduced, and the risk of position control error is improved, thereby improving the stability of data acquisition.
[0068] It is understood that in some embodiments of this utility model, the first conveyor belt 610 may be a synchronous belt or toothed belt with a toothed structure, and the first transmission tooth 620 is a wheel tooth meshing with the first conveyor belt 610. The first conveyor belt 610 and the first transmission tooth 620 are meshed through tooth grooves so that the rotating first transmission tooth 620 can drive the rotation of the first conveyor belt 610. The first conveyor belt 610 may also be a transmission chain, and the first transmission tooth 620 is a sprocket. The first conveyor belt 610 and the first transmission tooth 620 are meshed through chain links so that the rotating first transmission tooth 620 can drive the rotation of the first conveyor belt 610. The specific type of the first conveyor belt 610 in this application can be selected according to actual application, and this application does not limit it.
[0069] Reference Figure 13 In some embodiments of this utility model, the first moving part 230 is provided with a first connecting groove 232, and a first tooth 231 is located on the inner wall of the first connecting groove 232. The first conveyor belt 610 passes through the first connecting groove 232 and engages with the first tooth 231. By having the first conveyor belt 610 pass through the first connecting groove 232 and engage with the first tooth 231, the risk of the first tooth 231 disengaging from the first conveyor belt 610 is reduced, and the connection reliability between the first conveyor belt 610 and the first moving part 230 is improved.
[0070] Reference Figure 13In some embodiments of this utility model, the mechanical hook device proposed in this application further includes a tension wheel 630, which engages with the first conveyor belt 610. The tension wheel 630 is used to adjust the tension of the first conveyor belt 610, ensuring the engagement of the first tooth 231 and the first conveyor belt 610, and reducing the risk of slippage between the first tooth 231 and the first conveyor belt 610.
[0071] Reference Figure 2 and Figure 14 In some embodiments of this utility model, the vertical moving component 300 further includes a second frame 310, a second moving part 320, and a second transmission mechanism 700. The second frame 310 is fixedly connected to the first frame 210, enabling the first frame 210 to drive the second frame 310 to move along the extension direction of the second guide rail 311. The second frame 310 has a second guide rail 311 extending in the vertical direction, and the second moving part 320 is slidably connected to the second guide rail 311, enabling the second moving part 320 to move relative to the second guide rail 311. The second transmission mechanism 700 is used to drive the second moving part 320 to move. The fixed frame 410 is connected to the second moving part 320, enabling the second moving part 320 to drive the hook component 400 to move in the vertical direction, thereby allowing the hook 420 to approach the gift 900 in the vertical direction.
[0072] Reference Figure 15 and Figure 16 In some embodiments of this utility model, the second transmission mechanism 700 includes a second conveyor belt 710 and second transmission teeth 730 meshing with the second conveyor belt 710. The second conveyor belt 710 extends vertically, and two sets of second transmission teeth 730 are located at both ends of the second conveyor belt 710. The second transmission teeth 730 are rotatably connected to the second frame 310, so that the rotating second transmission teeth 730 can drive the second conveyor belt 710 to rotate. The second moving part 320 has a second tooth 322. Since the second tooth 322 meshes with the second conveyor belt 710, the rotating second conveyor belt 710 can drive the second moving part 320 to move, thereby driving the hook assembly 400 to move vertically. By meshing the second tooth 322 of the second conveyor belt 710 and the second moving part 320, the risk of the second moving part 320 slipping and wearing relative to the second conveyor belt 710 is reduced, as is the risk of the second moving part 320 slipping relative to the second conveyor belt 710 and being unable to lift the gift 900. This reduces the risk of lost movement steps in the second moving part 320, thereby reducing position control errors and improving data acquisition stability.
[0073] It is understood that in some embodiments of this utility model, the second conveyor belt 710 can be a synchronous belt or toothed belt with a toothed structure, and the second transmission tooth 730 is a wheel tooth meshing with the second conveyor belt 710. The second conveyor belt 710 and the second transmission tooth 730 are meshed through tooth grooves so that the rotating second transmission tooth 730 can drive the rotation of the second conveyor belt 710. The second conveyor belt 710 can also be a transmission chain, and the second transmission tooth 730 is a sprocket. The second conveyor belt 710 and the second transmission tooth 730 are meshed through chain links so that the rotating second transmission tooth 730 can drive the rotation of the second conveyor belt 710. The specific type of the second conveyor belt 710 in this application can be selected according to actual application, and this application does not limit it.
[0074] Reference Figure 16 In some embodiments of this utility model, the second moving part 320 is provided with a second connecting groove 323, and the second tooth 322 is located on the inner wall of the second connecting groove 323. The second conveyor belt 710 passes through the second connecting groove 323 and engages with the second tooth 322. Since the second conveyor belt 710 passes through the second connecting groove 323, the risk of the second tooth 322 disengaging from the second conveyor belt 710 is reduced, and the connection reliability of the second moving part 320 and the second conveyor belt 710 is improved.
[0075] Reference Figure 2 , Figure 15 and Figure 17 In some embodiments of this utility model, the second transmission mechanism 700 is further provided with a counterweight assembly 720. The counterweight assembly 720 has a third tooth 721, which meshes with the second conveyor belt 710, so that the rotating second conveyor belt 710 can drive the counterweight assembly 720 to move in the up-down direction. The counterweight assembly 720 and the second moving part 320 are located on both sides of the second conveyor belt 710, and the movement trajectories of the counterweight assembly 720 and the second moving part 320 are opposite. When the second moving part 320 moves from top to bottom, the counterweight assembly 720 moves from bottom to top. By having the counterweight assembly 720 and the second moving part 320 located on both sides of the second conveyor belt 710, the force balance of the rotating second conveyor belt 710 is improved, so that the torque required to drive the second conveyor belt 710 to rotate is smaller, thereby reducing the driving energy consumption of the rotating second conveyor belt 710. At the same time, the weight of the gift 900 that the hook 420 can hook is increased, improving the reliability of the mechanical hook hand device.
[0076] Reference Figure 17In some embodiments of this utility model, the counterweight assembly 720 has a third connecting groove 722, and a third tooth 721 is located on the inner wall of the third connecting groove 722. The second conveyor belt 710 passes through the third connecting groove 722 and engages with the third tooth 721. Since the second conveyor belt 710 passes through the third connecting groove 722, the risk of the third tooth 721 disengaging from the second conveyor belt 710 is reduced, and the connection reliability of the counterweight assembly 720 and the second conveyor belt 710 is improved.
[0077] Reference Figure 14 In some embodiments of this utility model, the second frame 310 has a third guide rail 312 extending in the vertical direction, and the counterweight assembly 720 is slidably connected to the third guide rail 312. The rotating second conveyor belt 710 drives the counterweight assembly 720 to move along the third guide rail 312, thereby improving the stability of the counterweight assembly 720 moving in the vertical direction.
[0078] Reference Figure 2 and Figure 14 In some embodiments of this utility model, the mechanical hook device proposed in this application further includes a third frame 800, which extends vertically. A second moving part 320 and a fixed frame 410 are connected to both ends of the third frame 800. The second moving part 320 drives the third frame 800 to move, thereby driving the fixed frame 410 to move vertically. The third frame 800 is fitted onto the outer peripheral wall of the second frame 310. The hooking component 400 is located below the vertical moving component 300 to prevent the vertical moving component 300 from obstructing the rotation of the hook 420 to hook the gift 900.
[0079] Understandably, one set of the two sets of first transmission teeth 620 is connected to a motor or other driving component to drive the first transmission teeth 620 to rotate, thereby driving the first conveyor belt 610 to rotate. Similarly, one set of the two sets of second transmission teeth 730 is connected to a motor or other driving component to drive the second transmission teeth 730 to rotate, thereby driving the second conveyor belt 710 to rotate.
[0080] It is understood that the motor can be used to drive the first transmission gear 620 and the second transmission gear 730 to rotate, or other driving components can be used. The choice can be made according to the actual application, and this application does not limit it here.
[0081] Based on the aforementioned mechanical hook device, this application also proposes a gift machine, including the aforementioned mechanical hook device and a cabinet. The cabinet has space for grabbing a gift 900, and a mounting bracket 100 is fixedly connected inside the cabinet. The cabinet is provided with a gift outlet for retrieving the gift 900. At least one gift 900 is placed inside the cabinet, and the mechanical hook device is controlled so that the hook 420 grabs the gift 900.
[0082] Reference Figure 1In some embodiments of this utility model, when the mechanical hook hand device and gift machine proposed in this application are in use: when the horizontal moving component 200 and the vertical moving component 300 are in their initial positions, the gift outlet for personnel to retrieve the gift 900 is located below the hooking component 400, and the hook 420 is arranged horizontally. After the personnel control the horizontal moving component 200 and the vertical moving component 300 to move to the designated position, the personnel press the designated button, so that the control signal is transmitted to a mechanical hook hand device, and drives the drive mechanism 450 to start. The drive mechanism 450 drives the first rotating wheel 470 to rotate, drives the linkage mechanism 500 and the second rotating wheel 480 to rotate, and then drives the hook 420 to rotate toward the gift 900 and hook the gift 900. The hook 420 is arranged vertically. If hook 420 catches gift 900, vertical moving component 300 and horizontal moving component 200 move hook 420 and gift 900 to their initial positions. Drive mechanism 450 drives first rotating wheel 470 to rotate, which in turn drives linkage mechanism 500 and second rotating wheel 480 to rotate, thereby causing hook 420 to rotate to a horizontal position. This allows gift 900 to slide off hook 420 and fall into the gift exit, where personnel can retrieve gift 900. If hook 420 does not catch gift 900, vertical moving component 300 and horizontal moving component 200 move hook 420 and gift 900 to their initial positions. Drive mechanism 450 drives first rotating wheel 470 to rotate, which in turn drives linkage mechanism 500 and second rotating wheel 480 to rotate, thereby causing hook 420 to rotate to a horizontal position.
[0083] Reference Figure 1 and Figure 9 Understandable Figure 1 The 420-inch center hook is horizontally arranged. Figure 9 The 420-inch central hook is arranged vertically.
[0084] In summary, this application proposes a mechanical hook device, including a mounting frame 100, a moving unit, and a hooking assembly 400. When the moving unit moves the hooking assembly 400 to a preset position, the drive mechanism 450 drives the first connecting rod 430 to move around the first axis 401. Since the two ends of the elastic member 440 abut against the inside of the first connecting rod 430 and the linkage mechanism 500 respectively, under the elastic force of the elastic member 440, the rotating first connecting rod 430 drives the linkage mechanism 500 to move, causing the second connecting rod 460 to rotate around the second axis 402, thereby causing the hook 420 to rotate around the second axis 402 and move towards the gift 900. If the angle between the hook 420 and the gift 900 is incorrect when the hook 420 rotates, causing the hook 420 to collide with the gift 900 and generate a momentary impact, and the gift 900 obstructs the rotation of the hook 420, the second connecting rod 460 will stop rotating. The drive mechanism 450 will continue to drive the first connecting rod 430 to rotate, causing the linkage mechanism 500 to swing around the second connecting rod 460. The rotating first connecting rod 430 compresses the elastic element 440 to absorb the impact, preventing the hook 420 from colliding with the gift 900 and transmitting the momentary impact to the drive mechanism 450. This reduces the risk of damage to the drive mechanism 450 caused by the momentary impact and saves maintenance costs.
