Abstract
Description
Technical Field
[0001] The utility model relates to a pusher component and a rotorcraft structure with the pusher component. Background Art
[0002] During the sorting process of the rotorcraft mahjong machine, a motor is usually required to push the mahjong tiles into a circular track through a pushing head and a pushing base. The traditional pushing head is fixedly connected to the pushing base and cannot rotate. Among them, the pushing head, driven by the motor, first places the mahjong tiles coming out of the object outlet on the receiving seat. At this time, the mahjong tiles are facing the pushing head, that is, the pushing surface of the pushing head is parallel to the contacted surface of the mahjong tiles, but when entering the circular track, the angle changes. During the pushing process, only one side of the pushing surface of the pushing head contacts the contacted surface of the mahjong tiles. At this time, the entering mahjong tiles collide with the existing mahjong tiles, which makes a lot of noise. In addition, long-term collision will cause damage. Therefore, this type of structure for the rotorcraft structure needs to be improved.

[0034] refer to Figures 1 to 8 As shown, the utility model discloses a pushing component. According to one embodiment, the pushing component includes a pushing head 1 and a pushing base 2 placed under the pushing head 1. A first through hole 111 for setting a bearing 112 is opened on the pushing head 1, and a second through hole 211 is provided on the pushing base 2. A screw 3 passes through the middle hole of the bearing 112, and the lower part of the screw 3 is screwed with the second through hole 211. The upper part of the screw 3 is outer-circuited with the bearing 112, and the nut of the screw 3 is located on the upper part of the bearing 112 to prevent the bearing 112 from running out. In this way, the pushing head 1 can rotate on the pushing base 2, and then a driving member is connected to the pushing base 2. The driving member drives the pushing head 1 to push the object into a desired position.
[0035] Furthermore, the driving member is a motor.
[0036] Furthermore, the pushed object is a mahjong tile, which is generally a commonly used rectangular parallelepiped.
[0037] In a further embodiment, the pusher head 1 has a bottom plate 11 with a first through hole 111, the pusher base 2 has a top plate 21 with a second through hole 211, the bottom plate 11 has a horizontal bottom surface 113, the top plate 21 has a horizontal top surface 212, and the horizontal bottom surface 113 can rotate on the horizontal top surface 212 through the bearing 112. For regular objects, such as the bottom surface of the object and the surface pushed and contacted by the pusher head 1 are horizontal and vertical planes, the bottom plate 11 is set to the horizontal bottom surface 113, and the top plate 21 is set to the horizontal top surface 212. Such horizontal pushing is more conducive to pushing the object into the desired position.
[0038] refer to Figure 3 to Figure 4 As shown, in a specific embodiment, the pusher head 1 is provided with a limiting movable portion, and a limiting member is fixedly provided on the top plate 21, and the limiting member limits the rotation angle of the pusher head 1 in the limiting movable portion.
[0039] In a specific embodiment, the limiting movable part includes a limiting movable hole 15 with an arc set on the bottom plate 11, and the limiting member is a pin 214 fixed on the top plate 21 and passing through the limiting movable hole 15, so that the rotation angle of the pusher head 1 is limited.
[0040] Furthermore, the pin 214 is located in the middle of the limiting movable hole 15 , and the pusher head 1 can rotate around the pin 214 in the limiting movable hole 15 in the clockwise direction and the counterclockwise direction.
[0041] Furthermore, a torsion spring 215 is wound around the pin 214, so that the pusher head 1 can return to its original position after rotating in clockwise and counterclockwise directions.
[0042] Furthermore, the rotation angle between the pin 214 and the right end of the limiting movable hole 15 is γ1, and the rotation angle between the pin 214 and the left end of the limiting movable hole 15 is γ2, and the angles γ1 and γ2 are both 0-30°.
[0043] Furthermore, the angles γ1 and γ2 are both 25°, and the driving member drives the pushing head 1 to push the object into the desired position. When the desired position is a circular orbit, for example, when the pushing head 1 rotates counterclockwise, that is, γ1, the rotation angle is 25°, allowing it to enter the circular orbit more smoothly.
[0044] refer to Figures 5 to 8 As shown, in a specific embodiment, the position-limiting movable part includes a position-limiting movable cavity 12, the position-limiting movable cavity 12 has an opening 121, and position-limiting stoppers 1211 are respectively provided on both sides of the opening 121;
[0045] The limiting member is a limiting pin 213, which includes a limiting column 2131 longitudinally fixed on the top plate 21 and a limiting rod 2132 vertically fixed on the limiting column 2131. The pusher head 1 rotates so that the limiting stoppers 1211 on both sides touch the limiting rod 2132 to be limited.
[0046] The limiting rod 2132 is located between the limiting blocks 1211 on both sides. The limiting blocks 1211 on both sides respectively form an angle α and an angle β with the limiting rod 2132 . The angles of the angle α and the angle β are both 0-30°.
[0047] The angles α and β are the same, both 25°. The driving member drives the pusher head 1 to push the object into the desired position. When the desired position is a circular track, for example, when the pusher head 1 rotates counterclockwise, that is, angle α, the rotation angle is 25°, so that it enters the circular track more smoothly.
[0048] refer to Figure 1 , 3 As shown in FIG. 5 , in a specific embodiment, the pusher base 2 includes an L-shaped connecting plate 22 vertically connected to the top plate 21 , so that the driving member drives the pusher head 1 to rotate horizontally.
[0049] refer to Figure 1 , 2As shown in Figures 3 and 5, in a specific embodiment, the pusher head 1 includes a left vertical plate 13 and a right vertical plate 14, the left vertical plate 13 has a left pushing surface 131, the right vertical plate 14 has a right pushing surface 141, the left pushing surface 131 and the right pushing surface 141 are in the same plane and parallel to the horizontal bottom surface 113. The driving member is such as a motor, and the motor drives the pusher head 1 to push objects such as mahjong tiles. When the required position is a circular track, the left pushing surface 131 and the right pushing surface 141 of the pusher head 1 are parallel to the surface of the mahjong tiles, so that the surfaces overlap, thereby improving the pushing effect.
[0050] refer to Fig. 9 , 10 As shown, the utility model also discloses a rotorcraft structure having the above pusher assembly, wherein the pushed object is a mahjong tile, and the pusher head 1 is pushed into the circular track 42 by a driving member such as a motor;
[0051] In a specific embodiment, a machine base 4 is provided, on which an object outlet 41 and a circular track 42 with an open end are provided, and an object receiving seat 43 and an object pushing head 1 are provided at the open end of the circular track 42 near the object outlet 41, and an object pushing base 2 is provided under the object pushing head 1, and the object pushing base 2 is connected to a driving member, and a toggle head 44 is provided on one side of the object pushing head 1 to make it rotate, and the object pushing head 1 pushes the object on the object receiving seat 43 into the circular track 42 through the driving member;
[0052] Taking mahjong tiles as an example, the conventional pusher head 1 is fixedly connected to the pusher base 2 and cannot rotate;
[0053] The pusher head 1 of the utility model can rotate, and a toggle head 44 for rotating the pusher head 1 is provided on the machine base 4 located on one side of the pusher head 1. When the pusher head 1 is driven by the motor, the toggle head 44 toggles the pusher head 1, and the pusher head 1 rotates and contacts the mahjong tiles on the receiving seat 43. The mahjong tiles also rotate, and the rotation angle matches the entrance of the circular track 42. During this process, the mahjong tiles and the pusher head 1 are always facing each other, that is, the pushing surface of the pusher head 1 is always parallel to the contacted surface of the mahjong tiles. In this case, the collision sound of the entering mahjong tiles and the existing mahjong tiles is very light, and the noise is very small, which reduces the probability of mahjong tiles being damaged by long-term collision.
