DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] This specific embodiment is a mini claw crane, and its structural schematic diagram is as Figures 1 - 4As shown in the figure, it includes a claw machine body 1. Inside the claw machine body 1, a placement plate 2 is fixedly connected to the inner wall. A number of movable openings 17 are opened at the top of the placement plate 2. A rectangular block 18 is slidably connected to the inner wall of the movable opening 17. The top of the rectangular block 18 extends above the placement plate 2 and is fixedly connected to a push plate 19. A mounting shaft 3 is fixedly connected to the bottom of the placement plate 2. An upper gear 4 is assembled on the side wall of the mounting shaft 3 through a bearing. An upper circular plate 5 is assembled on the side wall of the mounting shaft 3 through a bearing. The top of the upper circular plate 5 is fixedly connected to the bottom of the upper gear 4. At the positions near the left and right sides of the bottom of the upper circular plate 5, upper transmission rods 15 are respectively movably connected. The tops of the two upper transmission rods 15 are movably connected to the bottoms of the rectangular blocks 18 on the left and right sides through a rotating shaft. A lower gear 9 is movably connected to the side wall of the mounting shaft 3 through a bearing. At the position near the bottom of the side wall of the mounting shaft 3, a lower circular plate 10 is movably connected through a bearing. The top of the lower circular plate 10 is fixedly connected to the bottom of the lower gear 9. At the positions near the front and back sides of the bottom of the lower circular plate 10, lower transmission rods 16 are respectively movably connected. The tops of the two lower transmission rods 16 are respectively movably connected to the bottoms of the rectangular blocks 18 on the front and back sides through a rotating shaft. A transmission mechanism is arranged below the placement plate 2. The transmission mechanism is movably connected to the upper gear 4 and the lower gear 9.

[0023] The claw machine body 1 in this technical solution is a common mini claw machine on the market and belongs to common knowledge, so it will not be described in detail in this technical solution.

[0024] As Figures 2 - 4 shown in the figure, the transmission mechanism includes an upper rack 6. The upper rack 6 is located on the right side of the upper gear 4. The upper rack 6 meshes with the upper gear 4. The front end of the upper rack 6 is fixedly connected to an upper pull rod 7. The upper pull rod 7 is arranged in an L shape. The front end of the upper pull rod 7 penetrates through the claw machine body 1 and is movably connected to the claw machine body 1. A lower rack 11 is arranged on the left side of the lower gear 9. The lower rack 11 meshes with the lower gear 9. The front end of the lower rack 11 is fixedly connected to a lower pull rod 12. The lower pull rod 12 is arranged in an L shape. The front end of the lower pull rod 12 penetrates through the claw machine body 1 and is movably connected to the claw machine body 1.

[0025] The upper circular plate 5 and the lower circular plate 10 can be driven to rotate through the upper pull rod 7 and the lower pull rod 12, and the rotation will pull the upper transmission rod 15 and the lower transmission rod 16 to move towards the center, enabling the push plate 19 to push the prizes towards the middle. Among them, the upper pull rod 7 and the lower pull rod 12 are made of steel, which is a relatively hard material, so that the upper pull rod 7 and the lower pull rod 12 will not deform during use.

[0026] Among them, a baffle 14 is fixedly connected to the position near the rear side of the bottom of the placement plate 2. Pull springs 13 are respectively fixedly connected to the rear ends of the upper rack 6 and the lower rack 11. The rear ends of the pull springs 13 are fixedly connected to the baffle 14. Through the pull springs 13, the upper rack 6 and the lower rack 11 stretched forward can be pulled back to the initial position, which can improve the convenience and safety of use.

[0027] In addition, the front ends of the upper pull rod 7 and the lower pull rod 12 respectively extend to the front side of the claw machine body 1 and are fixedly connected with pull rings 8. The cross-sections of the upper pull rod 7 and the lower pull rod 12 are both rectangular. By means of the upper pull rod 7 and the lower pull rod 12 with rectangular cross-sections, the upper pull rod 7 and the lower pull rod 12 will not rotate or swing left and right during use, so that the upper rack 6 and the lower rack 11 remain engaged with the upper gear 4 and the lower gear 9.

[0028] Among them, the top of the push plate 19 is tapered. Cover plates 20 are respectively fixedly connected to the sides of the push plate 19 close to the bottom and opposite to the center of the placement plate 2. The tapered push plate 19 can prevent the push plate 19 from clamping other objects when returning to the initial position, avoiding jamming. Moreover, the cover plates 20 can prevent smaller prizes from falling into or getting stuck in the movable opening 17, effectively improving the stability of use.

[0029] In addition, a plurality of rectangular blocks 18 are arranged in an annular array. Sliders are fixedly connected to the side walls of the rectangular blocks 18, and sliding grooves matching the sliders are formed in the inner wall of the movable opening 17. The rectangular blocks 18 arranged in an annular array make the rectangular blocks 18 located at the center of the edge of the placement plate 2, making it more stable to use.

[0030] Working principle: When this technical solution is in use, first place the claw crane body 1 in a suitable place. Next, after putting in the prizes, it can be used normally. When a customer is using it, if the grabbed prize falls to the edge of the placement board 2 and the mechanical claw cannot grab it again, the prize can be pushed towards the center of the placement board 2. If the prize is at the front or rear side above the placement board 2, the pull ring 8 can be pulled forward to stretch the lower tension spring 13 below, causing the lower rack 11 to drive the lower circular plate 10 to rotate, so that the lower circular plate 10 pulls the rectangular blocks 18 and the push plates 19 on both the front and rear sides to move towards the middle through the lower transmission rod 16. In this way, the push plates 19 on both the front and rear sides can push the prizes at the edge towards the middle, so that the mechanical claw can grab the prizes that the customer likes again. After the pushing is completed, release the pull ring 8, and simultaneously the lower tension spring 13 pulls the lower rack 11 and the lower pull rod 12 to move backward, causing the lower circular plate 10 to rotate back to the initial position. When the prize that the customer likes falls to the left and right edge positions at the top of the placement board 2, the pull ring 8 can be pulled to move the upper pull rod 7 and the upper rack 6 forward to stretch the upper tension spring 13 above, causing the upper circular plate 5 to rotate and then pull the rectangular blocks 18 and the push plates 19 on both the front and rear sides to move towards the center of the placement board 2. In this way, the prizes at the left and right edge positions on both the front and rear sides can be moved towards the middle, so that the mechanical claw can grab the prizes. After the pushing is completed, release the pull ring 8, and simultaneously the upper tension spring 13 above pulls the upper rack 6 and the upper pull rod 7 to move backward, causing the upper circular plate 5 to rotate to the initial position. Simultaneously, the push plates 19 on both the left and right sides will also return to the initial position. The above operations can effectively improve the convenience of using the claw crane body 1.

[0031] All technical features in this embodiment can be freely combined according to actual needs.

[0032] The above embodiment is a preferred implementation solution of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious replacement without departing from the concept of this technical solution is within the protection scope of the present utility model.
