Description

Technical Field

[0001] The utility model relates to the technical field of amusement equipment, in particular to a connecting rod pushing device. Background Art

[0002] In an amusement device that scores points by pushing objects on a game table, the specific gameplay is that the player presses a control button to control a push rod to push objects on the game table off the game table to score points. Since the push rod needs to return to its original position after each push, the amusement device requires a push rod device that can be pushed repeatedly.

[0003] like Figure 1 As shown, most of the existing push rod devices are composed of a rocker. When started, the push rod is pushed forward along the trajectory and then returns to the initial position according to the original trajectory. However, since some game tables are provided with transmission tracks, the game tables are continuously replenished by conveying items through the transmission tracks. Therefore, in addition to pushing items forward when started, the push rod will often touch items during the return process along the original trajectory, resulting in the situation of pushing items backward. This not only affects the number and distribution of items on the game table, but also the push rod is easy to push the items to the wall when the device is pushed backward, causing damage to the push rod device and the items.

[0014] Beneficial effects of the utility model:

[0015] (1) The connecting rod pushing device of the utility model adopts a pushing method with a circular motion trajectory. The crank is driven by the driving device to rotate counterclockwise to drive the push rods on the upper connecting rod and the lower connecting rod to move. Under the constraint of the auxiliary rocker, the lower connecting rod makes the push rod have a stable motion trajectory, thereby driving the push shovel to move along a clockwise circular trajectory.

[0016] (2) The dozer blade of the utility model adopts a movable connection structural design. The dozer blade can move up and down along the dozer blade bracket. When the dozer blade is stuck by an object during the downward movement, the dozer blade can move upward along the dozer blade bracket to prevent the dozer blade from getting stuck. After that, when the dozer blade does not contact the obstructing object, the dozer blade will slide to the initial position along the dozer blade bracket under the action of gravity, thereby effectively avoiding the dozer blade from getting stuck during the downward movement, and having strong anti-interference ability.

[0030] Specifically, when the drop opening of the game table 100 is located at the left end, the push shovel assembly 7 will move in a circular trajectory in the clockwise direction; when the drop opening of the game table 100 is located at the right end, the push shovel assembly 7 will move in a circular trajectory in the counterclockwise direction; more specifically, the push shovel assembly 7 first descends to the surface of the game table 100, and pushes the objects on the game table 100 to make them fall, and then the push shovel assembly 7 climbs upward for a distance and then moves backward to return to the starting point, thereby avoiding the objects on the game table and preventing the push shovel assembly 7 from colliding with the objects when moving backward.

[0031] Specifically, the mounting frame 1 of the present embodiment includes a top cover plate 11, which can be installed above the game table 100 to provide sufficient space for the device to prevent obstacles from appearing on the movement trajectory of each part.

[0034] Specifically, the push rod 6 of this embodiment includes a first connecting portion 61, which is movably connected to the upper connecting rod 5 and the lower connecting rod 4 respectively through the second movable shaft 52, and the lower end of the first connecting portion 61 is connected to the second connecting portion 62, and the connection between the second connecting portion 62 and the first connecting portion 61 is an obtuse-angle structure, and the lower end of the second connecting portion 62 is connected to the third connecting portion 63, and the connection between the third connecting portion 63 and the second connecting portion 62 is an obtuse-angle structure, so that the third connecting portion 63 is in a downward tilted state, and the obtuse angles of the two obtuse-angle structures are in opposite directions, so that the push rod 6 is in a Z-shaped structure as a whole, and the push shovel assembly 7 is installed at the lower end of the third connecting portion 63. At this time, the push shovel assembly 7 is in a downward tilted state, so that the push shovel assembly 7 can push objects.

[0035] Preferably, the first connection portion 61 , the second connection portion 62 and the third connection portion 63 of this embodiment are an integrally formed structure.

[0036] The overall working principle of the utility model:

[0038] The drop opening of the game table 100 of this embodiment is located at the left end. When the player presses the game button connected to the external controller, the external controller controls the driving device 2 to start moving. The driving device 2 drives the crank 3 to rotate counterclockwise. At the same time, the crank 3 drives the lower connecting rod 4 to move. Under the constraint of the auxiliary rocker 8, the lower connecting rod 4 makes the push rod 6 have a stable movement trajectory, thereby driving the push shovel 72 to move along a clockwise circular trajectory. The push shovel 72 first descends to the game table 100, and then steadily pushes the object forward. After pushing forward, it first climbs a distance and then moves backward to the starting point, effectively avoiding the problem of damage to the object caused by the push shovel 72 pushing the object backward and the collision between the push shovel 72 and the object;

[0039] At the same time, the push rod 6 will drive the upper connecting rod 5 to move back and forth along the arc trajectory during the movement. An induction switch 9 is set at the starting point of the movement trajectory of the upper connecting rod 5. The induction switch 9 is connected to the external controller. When the shovel 72 returns to the starting point, the upper connecting rod 5 will touch the induction switch 9 driven by the push rod 6. The induction switch 9 will send a signal to the external controller, and the external controller will control the driving device 2 to stop working, thereby completing a round of play.
