The hook structure is rotatably connected with the body, the rocker arm structure is rotatably connected with the body, the driving structure is connected with the body and the rocker arm structure, and the driving structure is configured to drive the rocker arm structure to rotate relative to the body. The hook structure comprises a hook holding portion and a limited portion, the hook holding portion is located on one side of a rotating shaft of the hook structure, the limited portion is located on the other side of the rotating shaft of the hook structure, a blocking end is arranged on the rocker arm structure, and the driving structure is configured to drive the blocking end to rotate to abut against the limited portion or to be far away from the limited portion.
Fig. 1-2 schematically illustrate a block diagram of a cargo throwing device according to an embodiment of the present disclosure.
As shown in fig. 1 and 2, the cargo throwing device 10 according to the embodiment of the present disclosure includes at least a body 100, a hook structure 200, a swing arm structure 300, and a driving structure 400.
The hook structure 200 is rotatably coupled with the body 100 according to the embodiment of the present disclosure. The rocker arm structure 300 is rotatably connected to the body 100, the driving structure 400 is connected to the body 100 and the rocker arm structure 300, and the driving structure 400 is disposed to drive the rocker arm structure 300 to rotate relative to the body 100.
In one instance, the rocker arm structure 300 is configured to cooperate with the hook structure 200 to prevent rotation of the hook structure 200 relative to the body 100.
For example, the hook structure 200 may be used to carry cargo, and the rocker structure 300 may be in contact with the hook structure 200, for example, to block the hook structure 200 from rotating relatively with the body 100, so as to prevent the cargo on the hook structure 200 from falling off. That is, when the cargo throwing is not required, the swing arm structure 300 and the hook structure 200 form a mechanical locking state to prevent the hook structure 200 from rotating with respect to the body 100, so as to prevent the cargo on the hook structure 200 from falling off.
In another case, the swing arm structure 300 is rotated relative to the body 100 by the driving structure 400, so that the hook structure 200 is rotated relative to the body 100 by the weight of the cargo to disengage the cargo from the hook structure 200.
For example, when a cargo is required to be thrown, the driving structure 400 drives the swing arm structure 300 to rotate relative to the body 100, so that the swing arm structure 300 is no longer in contact with the hook structure 200, and the hook structure 200 is not blocked by the swing arm structure 300. After the hook structure 200 is no longer in contact with the rocker arm structure 300, the hook structure 200 can rotate relative to the body 100 under the action of gravity of the cargo, so that the cargo on the hook structure 200 falls off from the hook structure 200, and cargo throwing is completed.
Fig. 3 schematically illustrates a mounted cargo schematic according to an embodiment of the disclosure.
FIG. 4 schematically illustrates a block diagram of the interaction of a hook structure and a rocker arm structure according to an embodiment of the disclosure.
As shown in fig. 3 and 4, the hook structure 200 includes a hooking portion 210 located at one side of a rotation axis (a first rotation axis 240) of the hook structure 200 and a restricted portion 220 located at the other side, a blocking end 310 is provided on the rocker arm structure 300, and the driving structure 400 is configured to drive the blocking end 310 to rotate against the restricted portion 220 or to be away from the restricted portion 220.
The rocker arm structure 300 and the hook structure 200 cooperating to prevent rotation of the hook structure 200 relative to the body 100 includes: the drive structure 400 is configured to drive the blocking end 310 to rotate against the restricted portion 220 to prevent the hook structure 200 from rotating relative to the body 100.
The driving structure 400 drives the swing arm structure 300 to rotate relative to the body 100, so that the hook structure 200 rotates relative to the body 100 under the gravity of the cargo comprises: the driving structure 400 drives the blocking end 310 away from the restricted portion 220 so that the hook structure 200 rotates relative to the body 100 under the weight of the cargo.
In addition, the driving structure 400 only needs to drive the rocker arm structure 300 to rotate relative to the body 100 so that the rocker arm structure 300 is not in contact with the hook structure 200, and the driving force of the driving structure 400 is far less than the gravity of the goods, so that the driving requirement on the driving structure 400 is reduced, and the driving cost is reduced.
In the disclosed embodiment, the cargo is restricted from being disengaged from the hook structure by the mechanical dead lock condition formed by the rocker arm structure and the hook structure. When the goods are thrown, the driving structure drives the rocker arm structure to move so as to relieve the mechanical locking state of the rocker arm structure and the hook structure, and the hook structure rotates under the action of gravity of the goods to finish the goods throwing. Therefore, the cargo throwing device can make the cargo throwing process more convenient and faster.
Fig. 5 schematically shows a body structure view of a cargo throwing device according to an embodiment of the present disclosure.
As shown in fig. 5, the body 100 includes, for example, a front side plate 100a and a rear side plate 100 b. Wherein the hook structure 200 and the swing arm structure 300 are rotatably connected to the front side plate 100a and the rear side plate 100b, for example. That is, the coupling portion of the hooking structure 200 to the body 100 is between the front and rear side plates 100a and 100b, and the coupling portion of the swing arm structure 300 to the body 100 is between the front and rear side plates 100a and 100 b.
As shown in fig. 3, the cargo 20 is, for example, mounted on the hook structure 200. When the driving structure 400 drives the rocker arm structure 300 to rotate counterclockwise, the rocker arm structure 300 is disengaged from the hook structure 200. Without the blocking of the swing arm structure 300, the hook structure 200 is rotated counterclockwise, so that the cargo 20 loaded on the hook structure 200 is separated from the hook structure 200.
The stop structure 500 of the cargo device 10 is described below in conjunction with fig. 3 and 6.
FIG. 6 schematically illustrates a block diagram of a stop structure according to an embodiment of the disclosure.
As shown in fig. 6, the cargo jettisoning device 10 further includes a stop structure 500.
According to the embodiment of the present disclosure, the stopping structure 500 includes a first end and a second end, the first end of the stopping structure 500 is rotatably connected with the body 100, and the second end of the stopping structure 500 is mutually matched with the hooking structure 200. For example, the second end of stop structure 500 includes a recess in which the tail of hook structure 200 is located when the second end of stop structure 500 is interfitted with hook structure 200 (see FIG. 2).
As shown in fig. 3, when the cargo 20 needs to be hung on the hook structure 200, the stopping structure 500 may be pushed open, so that the stopping structure 500 rotates counterclockwise relative to the body 100 under the action of external force, so that the second end of the stopping structure 500 is far away from the hook structure 200.
For example, stop 500 may be rotated counterclockwise under an external force to move away from hook structure 200 in direction a such that stop 500 is at a second end away from the rear of hook structure 200 to facilitate the hanging of cargo 20 on hook structure 200. Wherein the goods 20 may comprise a ring by which the goods may be hung on the hook structure 200.
After the cargo is hung on the hook structure 200, the stopper structure 500 is rotated clockwise relative to the body 100 after the external force is withdrawn, so that the second end of the stopper structure 500 is close to the hook structure 200, for example, so that the second end of the stopper structure 500 is close to the tail of the hook structure 200, i.e., the tail of the hook structure 200 is located in the groove of the second end of the stopper structure 500.
The hook structure 200 and the swing arm structure 300 of the cargo throwing device 10 will be described below with reference to fig. 3 and 4.
As shown in fig. 3, the hook structure 200 includes a restricted portion 220 and the rocker arm structure 300 includes a blocking end 310. Wherein the blocking end 310 is configured to contact the restricted portion 220 to restrict the hook structure 200 from rotating counterclockwise relative to the body 100.
Wherein, when the driving structure 400 drives the rocker arm structure 300 to rotate counterclockwise relative to the body 100, the blocking end 310 is disengaged from the limited portion 220, so that the hook structure 200 rotates counterclockwise relative to the body 100 under the gravity of the cargo to disengage the cargo from the hook structure 200.
As shown in FIG. 3, the rocker arm structure 300 further includes a connecting end portion 320 and a connecting middle portion 330.
Wherein the connecting end portion 320 is connected to the driving structure 400, for example, and the connecting middle portion 330 is connected to the body 100, for example. For example, the connecting middle portion 330 is rotatably connected with the body 100.
Wherein the distance H from the blocking end 310 to the connecting middle portion 3301Less than the distance H from the connecting end portion 320 to the connecting middle portion 3302。
Under the driving of the driving structure 400, the blocking end 310 is separated from the restricted portion 220 only by overcoming the contact friction force with the restricted portion 220, which is much smaller than the gravity of the cargo 20, thereby achieving a first-level labor saving effect. The blocking end 310 and the restricted portion 220 may be made of a material with a relatively small friction coefficient, such as a steel material, and the friction coefficient of the steel material may be 0.2.
The disclosed embodiment sets the distance H1Less than distance H2So that the rocker arm structure 300 forms a labor-saving lever, i.e. a secondary labor-saving effect.
