Description

Technical Field

[0001] The utility model relates to the technical field of game machine devices, in particular to an opening and closing structure of a fish head game machine. Background Art

[0002] A fish head game machine is a game device that imitates the opening and closing of a fish head. When the fish head opens, game coins are put into it. A circular induction sheet inside the fish head senses the game coins and transmits signals to a control device to obtain corresponding scores. In the design process of the movement of the fish head component structure in a fish head game machine, there are many structural problems that are difficult to achieve. With the increasing demand for product functions and the stricter control of enterprise costs, the requirements for the simplicity, stability, and efficiency of the transmission and movement of component structures are getting higher and higher.

[0003] In the traditional movement mode of component structures, often a motor drives a component. If different components need to achieve different movement effects at the same time, usually multiple different electronic signals need to be given or different transmission modes need to be designed for each component. However, this will undoubtedly increase the material cost of the enterprise and reduce the production efficiency of the enterprise.

[0004] To effectively solve these problems, this solution designs a new structure, providing a new idea for the development of the transmission and movement structure mode. Content of the Utility Model

[0008] To solve the above technical problems, the technical solution of the utility model is as follows: an opening and closing structure of a fish head game machine, including an installation panel and a plurality of fish head components detachably and fixedly arranged on the side of the installation panel. On the other side of the installation panel, a power component for driving the opening and closing of the fish head components is fixedly arranged. The fish head component includes a fish head 3D printing part, a fish tongue 3D printing part, and a circular induction sheet. The fish head 3D printing part is hinged to the fish tongue 3D printing part through a hinge, and a double torsion spring is arranged at the hinge. The circular induction sheet is fixedly arranged at the upper end of the fish tongue 3D printing part. A rotating frame is fixedly arranged at the rear side of the fish head 3D printing part, and a bearing is fixedly sleeved inside the rotating frame through a round shaft. The power component includes two motor seats fixedly arranged on the rear side of the installation panel. A rotating shaft is rotatably arranged between the motor seats.

[0018] 3. It realizes a novel transmission method in which the eccentric block drives the fulcrum of the lever structure and then drives the lever structure to move, successfully solving the structural problem of the regular movement of the components.

[0028] The following further details the present utility model with reference to the drawings.

[0029] Combined with the attached Figure 1 To the attached Figure 5, An opening and closing structure of a fish head game machine, including an installation panel 9 and a plurality of fish head components detachably and fixedly arranged on the side of the installation panel 9. A power component for driving the opening and closing of the fish head components is fixedly arranged on the other side of the installation panel 9. The fish head component includes a fish head 3D printing part 1, a fish tongue 3D printing part 2 and a circular induction sheet 7. The fish head 3D printing part 1 is hinged to the fish tongue 3D printing part 2 through a hinge 6, and a double torsion spring 5 is arranged at the hinge. The circular induction sheet 7 is fixedly arranged at the upper end of the fish tongue 3D printing part 2. A rotating frame 4 is fixedly arranged at the rear side of the fish head 3D printing part 1. A bearing 8 is fixedly sleeved inside the rotating frame 4 through a circular shaft. Through holes for the rotating frame 4 to pass through are arranged at corresponding positions on the installation panel 9 for each fish head component.

[0030] The power component includes two motor seats 11 fixedly arranged on the rear side of the installation panel 9. A rotating shaft 12 is rotatably arranged between the motor seats 11. A motor 10 for driving the rotation of the rotating shaft 12 is fixedly arranged outside one of the motor seats 11. Eccentric blocks 15 are fixedly arranged on the rotating shaft 12 through fixing codes 16 corresponding to each fish head component. The fixing angles of the plurality of eccentric blocks 15 on the rotating shaft 12 are different. The eccentric blocks 15 are in rolling contact connection with the bearings 8.

[0031] An induction sheet 13 is fixedly arranged on the rotating shaft 12. An induction light eye 14 is fixedly arranged at a position corresponding to the induction sheet 13 on the rear side of the installation panel 9. When the induction sheet 13 passes through the induction light eye 14, it blocks the light. The induction light eye 14 realizes electrical control by detecting the reaction signal of the blocked light. The induction light eye 14 is usually connected to an external controller to control the operation of the device.

[0032] A base 3 is fixedly arranged at the rear end of the fish tongue 3D printing part 2. The base 3 is fixedly connected to the installation panel 9 through bolts.

[0033] The specific working process of the present utility model is as follows: Before the present utility model is used, an external power supply is first connected. When the motor 10 starts to operate, it drives the rotating shaft 12 to rotate. The eccentric block 15 is tightly fixed to the rotating shaft 12. When the rotating shaft 12 rotates, the eccentric block 15 also rotates. The bearing 8 is in contact with the eccentric block 15. When the eccentric block 15 rotates, the bearing 8 moves along the edge of the eccentric block 15. Due to the shape design of the eccentric block 15 (as shown in the attached figure), the bearing 8 can move repeatedly along a specific trajectory. Figure 5 shown), the bearing 8 can move repeatedly along a specific trajectory.

[0034] The 3D printed fish head 1, the rotating frame 4 and the bearing 8 are fixed together. The 3D printed fish tongue 2 and the base 3 are also fixed together. The two are connected by a hinge 6, and a double torsion spring 5 is installed on the hinge 6. The double torsion spring 5 enables the entire fish head assembly to make an opening and closing movement of "opening the mouth" or "closing the mouth". At this time, this structure forms a "lever structure". The 3D printed fish head 1, the rotating frame 4 and the bearing 8 are connected, forming a "lever", and the position of the bearing 8 is an end point of the lever structure. If an external force acts on the end point, the lever structure will rotate.

[0035] When no force is applied to the bearing 8, the fish head structure will be in the "closed mouth" state. When the eccentric block 15 starts to rotate as the motor 10 operates, the eccentric block 15 will drive the bearing 8 to move. At this time, the entire fish head structure will slowly change from the "closed mouth" state to the "open mouth" state, and then slowly change from the "open mouth" state to the "closed mouth" state. The time for the rotating shaft 12 to rotate one week exactly enables the entire fish head structure to complete the action of "opening and closing the mouth".

[0036] The induction piece 13 is fixed on the rotating shaft 12. When the rotating shaft 12 rotates one circle, the induction piece 13 will be detected by the induction optical eye 14. Refer to the appendix Figure 4 , the circular induction piece 7 is fixed inside the 3D printed fish tongue 2. There is a hole in the middle of the 3D printed fish tongue 2. When the fish head assembly is in the "open mouth" state, if a gold coin (game coin) falls into the hole in the middle of the 3D printed fish tongue 2, it will be detected by the circular induction piece 7 and the signal will be transmitted to the external controller for scoring.

[0037] Refer to the appendix Figure 2 , appendix Figure 3 , multiple eccentric blocks 15 are fixed at different angles. When the rotating shaft 12 drives multiple eccentric blocks 15 to move together, the bearings 8 of the three fish head assemblies will be in different positions, which also causes the starting times of the multiple fish head assemblies to make the "open mouth" movement to be inconsistent, and the overall opening and closing rhythm to be different, thereby increasing the diversity and interest of the movement of the fish head structure.

[0038] The above describes the present utility model and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. All in all, if those of ordinary skill in the art are inspired by it and without departing from the creative purpose of the present utility model, without creative design, structures and embodiments similar to this technical solution should all fall within the protection scope of the present utility model.
