DETAILED DESCRIPTION

[0020] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings showing embodiments of the present invention.

[0021] See Figure 1-3 The utility model provides a rotatable gift hook mechanism, including a hanging rod 1, one end of the hanging rod 1 is provided with a rotation drive mechanism 3, the other end of the hanging rod 1 is provided with a bending portion 2, the function of the bending portion 2 is to hook the hanging rope 9 of the gift 7 to prevent the gift 7 from falling easily, and the rotation drive mechanism 3 is provided with a detection device 4 for detecting the initial position and rotation angle of the bending portion 2.

[0022] Furthermore, the detection device 4 includes a code disk 401, a first sensor 402 and a second sensor 403. The first sensor 402 and the second sensor 403 can use a through-type photoelectric sensor. The code disk 401 is provided with a circumferentially evenly distributed grating 404. The first sensor 402 is used in conjunction with the grating 404. The first sensor 402 calculates the rotation angle of the hanging rod 1 by checking the number of gratings passing through the detection area; the code disk 401 is provided with a through hole 405, and the through hole 405 is used in conjunction with the second sensor 403. When applied to push-rod gift amusement equipment, the bending portion 2 can be set to face vertically upward, and the through hole 405 is in the detection area of ​​the second sensor 403, which is defined as the initial state at this time.

[0023] Furthermore, the rotation drive mechanism 3 includes a motor 301 and a reducer 302. The motor 301 is connected to the reducer 302. The output end of the reducer 302 is connected to one end of the hanging rod 1 through a connecting shaft 303. When the motor 301 drives the reducer 302 to rotate, it will drive the hanging rod 1 to rotate, thereby rotating the bending part 2.

[0024] Furthermore, the code disc 401 is disposed on the connecting shaft 203 , and a center line of the code disc 401 coincides with a center line of the connecting shaft 203 .

[0025] Specifically, when the bending portion 2 is vertically upward, the through hole 405 on the code disk 401 is within the detection area of ​​the second sensor 402. At this time, the bending portion 2 is defined to be in an initial state. When the motor 301 and the reducer 302 drive the hanging rod 1 to rotate, the code disk 401 rotates accordingly, and the through hole 405 leaves the detection area of ​​the second sensor 403, that is, the second sensor 403 is triggered, and the trigger signal is fed back to the control system of the amusement device; during the rotation of the code disk 401, the light grating 404 passes through the detection area of ​​the first sensor 402, and the first sensor 402 feeds back the detection signal to the control system of the amusement device. The control system can convert the number of light grids passing through the first sensor 402 into the rotation angle of the hanging rod 1.

[0026] Furthermore, the gift hook mechanism includes a mounting shell 5, the motor 201 and the reducer 202 are installed in the mounting shell 5, and a mounting plate 6 is also provided in the mounting shell 5. The mounting plate 6 is provided at one end close to the reducer 201, and the two ends of the mounting plate 6 are fixedly mounted on the inner walls on both sides of the mounting shell 5.

[0027] Furthermore, a circular hole 10 is provided on the mounting plate 6 , and the output end of the reducer 201 is connected to a connecting shaft 203 , and the connecting shaft 203 passes through the circular hole 10 and is connected to one end of the hanging rod 1 .

[0028] Furthermore, the code disk 401 is arranged in the area where the connecting shaft 203 is located between the mounting plate 6 and the hanging rod 1 , and the first sensor 402 and the second sensor 403 are both mounted on the mounting plate 6 .

[0029] Working Principle: The gift hook mechanism of the present invention is installed in an amusement device for hanging gifts. By controlling the rotation of the hanging rod 1, the direction of the bent portion 2 is controlled. Due to the different directions of the bent portion 2, the difficulty of the gift falling when the push rod of the amusement device pushes the gift also varies, thereby achieving the difficulty of players obtaining the gifts in the amusement device, as follows:

[0030] like Figure 4 As shown, the gift 7 is hung on the hanging rod 1. At this time, the bending portion 2 of the hanging rod 1 is facing vertically upward, and the through hole 405 on the code disk 401 is within the detection area of ​​the second sensor 402. This is the initial state of the bending portion 2. When the gift 7 is subjected to a push or pull in the direction of the arrow 8, the hanging rope 9 cannot slide over the end of the bending portion 2. Therefore, no matter where the player operates the push rod of the amusement equipment to hit the gift 7, the gift 7 will never fall off the hook.

[0031] like Figure 5 As shown, after the control system of the amusement equipment controls the hanging rod 1 to rotate 90°, the bent portion 2 of the hanging rod 1 is facing horizontally. At this time, when the gift is subjected to a push or pull in the direction of the arrow 8, if the push rod hits the appropriate position of the gift 7, the hanging rope 9 can slide over the end of the bent portion 2, and the gift 7 can fall from the hook.

[0032] like Figure 6 As shown, after the control system of the amusement equipment controls the hanging rod 1 to rotate 180°, the bent portion 2 of the hanging rod 1 is facing vertically downward. At this time, when the gift 7 is pushed or pulled in the direction of the arrow 8, the hanging rope can easily slide over the end of the bent portion 2, and the gift 7 can easily fall off the hook.

[0033] The amusement equipment using the hook mechanism of this design can control the rotation of the hanging rod 1 to make the hook point in different directions, that is, during the switching process from vertical upward to vertical downward, the difficulty of the gift 7 falling is gradually switched from difficult to easy.

[0034] It should be noted that the technical solution of the present invention omits the specific structural description of the mechanical and electrical connections between the hook mechanism and the amusement equipment. This content belongs to the prior art. For those skilled in the art, although the description of the above part is omitted, the technical solution of the present invention is still a complete and feasible technical solution.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
