The first position of the holding claw 300 is that the compressor body 100 is not connected with the dustbin, and the second position of the holding claw 300 is that the hook portion 310 of the holding claw 300 is embedded into the groove of the dustbin to connect the compressor body 100 with the dustbin. In the process of switching the holding claw 300 from the first position to the second position, since the crank arm 220 and the first rocker 210 are both hinged to the mounting plate 200, the holding claw 300 is in a compound motion, the motion track of the hook portion 310 is an arc, and a part of the motion track moves up and down, so that the hook portion 310 can conveniently catch the garbage bin with a declined angle.
The holding claw 300 is limited by the crank arm 220 and the first rocker 210 and is driven by the thrust oil cylinder 400, so that the structure is simple and easy to realize, and the fault is not easy to occur; the embracing claw 300 can embrace and lock only by using one thrust oil cylinder 400, so that the cost is effectively reduced; the first rocker 210 and the crank arm 220 are hinged to the mounting plate 200, so that the holding claw 300 has a certain up-and-down moving space in the process of locking or unlocking the holding claw 300 with the dustbin, the holding claw 300 can be smoothly buckled into a groove of the dustbin and locks the dustbin when the dustbin is placed at an inclined angle, the requirement on the processing precision of equipment is not high, and the production and maintenance are facilitated.
In some embodiments of the present invention, the crank arm 220 comprises a short arm 221 and a long arm 222, wherein the end of the short arm 221 intersects with the end of the long arm 222, and the intersection point is hinged with the mounting plate 200; the long arm 222 is hinged with the holding claw 300, and the short arm 221 is connected with the telescopic end of the thrust cylinder 400.
In some embodiments of the present invention, the angle between the long arm 222 and the short arm 221 is less than 180 degrees. Specifically, as shown in fig. 1 and fig. 2, in the present embodiment, an included angle between the short rod and the long rod of the crank arm 220 is close to 90 degrees, and the most suitable included angle can be determined according to actual requirements or parameters such as the size and the interval of the mounting plate 200.
In some embodiments of the present invention, the end of the long arm 222 away from the short arm 221 is hinged to the holding claw 300, and the end of the short arm 221 away from the long arm 222 is connected to the telescopic end of the thrust cylinder 400.
In some embodiments of the present invention, the thrust cylinder 400 includes a connecting rod 230, and the telescopic end of the thrust cylinder 400 is connected with the short arm 221 through the connecting rod 230; two ends of the connecting rod 230 are respectively hinged with the short arm 221 and the telescopic end of the thrust cylinder 400. The end of the long arm 222 away from the short arm 221 is provided with a hinge hole for connecting with the clasping claw 300 through a hole pin, and the end of the short arm 221 away from the long arm 222 is also provided with a hinge hole and hinged with one end of the connecting rod 230.
In some embodiments of the present invention, the mounting plate 200 is further hinged with a second rocker 240, one end of the second rocker 240 is hinged with the mounting plate 200, and the other end is hinged with the hinged part of the connecting rod 230 and the thrust cylinder 400; the second rocking bar 240 is used for limiting the movement path of the telescopic end of the thrust cylinder 400. Specifically, the fact that the end of the second rocker 240, which is far away from the mounting plate 200, is hinged to the hinged position of the connecting rod 230 and the thrust cylinder 400 means that the two are connected through the same pin; the telescopic end of the thrust cylinder 400 is hinged to the end of the second rocker 240 far away from the mounting plate 200, so that the telescopic end of the thrust cylinder 400 is limited to perform circular motion only around the hinged position of the second rocker 240 and the mounting plate 200.
In some embodiments of the present invention, the second rocker 240 is mounted above the first rocker 210. As shown in fig. 1 and 2, the connecting rod 230 is not connected to the mounting plate 200, only the second rocking lever 240, the first rocking lever 210 and the crank arm 220 are hinged to the mounting plate 200, and it should be noted that the interval between the hinge point of the second rocking lever 240 and the mounting plate 200 and the hinge point of the first rocking lever 210 and the mounting plate 200 must be greater than the lengths of the second rocking lever 240 and the first rocking lever 210 in order to avoid obstructing the movement of the second rocking lever 240 and the first rocking lever 210. Likewise, the hinge point of the crank arm 220 to the mounting plate 200 and the hinge point of the second rocker 240 to the mounting plate 200 must be greater than the length of the long arm 222 and the length of the second rocker 240; the hinge point of the crank arm 220 to the mounting plate 200 and the hinge point of the first rocker 210 to the mounting plate 200 must also be greater than the length of the long arm 222 and the length of the second rocker 240. The clasping claw 300 is disposed between the first rocker 210 and the crank arm 220.
Further, as shown in fig. 2, at this time, when the holding claw 300 is located at the second position, the telescopic end of the thrust cylinder 400 is completely retracted, that is, the telescopic end of the thrust cylinder 400 cannot be retracted to the stroke end, and cannot be further retracted; the end of the connecting rod 230 far from the short arm 221 is higher than the hinged end of the short arm 221, at this time, if the trash bin is subjected to a vertically downward pulling force, that is, under the condition that the holding claw 300 is subjected to a vertical force, the holding claw 300 drives the long arm 222 of the connecting lever 220 to rotate around the hinged position of the long arm and the mounting plate 200, so as to drive the short arm 221 to synchronously rotate, but because the end of the connecting rod 230 far from the short arm 221 is higher than the hinged end of the short arm 221, the short arm 221 further pushes the end of the connecting rod 230 far from the short arm 221 to move upwards in the rotating process, but because the telescopic end of the thrust cylinder 400 is completely retracted at this time, the end of the connecting rod 230 far from the short arm 221 cannot continue to move upwards, so as to form a self-lock on the holding claw 300, so that the hook portion 310 of the holding claw 300 can firmly lock the trash bin, and cannot be unhooked from the trash bin even if the trash bin is pulled by an external force.
