Referring to fig. 2 to 4, fig. 2 is a schematic structural diagram of a lifting device in a lifting state according to an embodiment of the present invention; FIG. 3 is a schematic structural diagram of a lifting device in a retracted state according to an embodiment of the present invention; FIG. 4 is an exploded view of the lifting device disclosed in the preferred embodiment of the present invention.
The present disclosure provides a lifting device, which includes a first support 1, a second support 2, a lifting assembly 3, a rotating shaft 4 and a driving member 5.
The first support 1 is arranged opposite to the second support 2; the rotating shaft 4 is rotatably arranged on the first supporting part 1; the driving piece 5 is connected with the rotating shaft 4 to drive the rotating shaft 4 to rotate; in a specific implementation, the driving member 5 may be a rotary power mechanism, such as a motor, or a reciprocating power mechanism, such as a hydraulic cylinder, an air cylinder, or the like.
The lifting assembly 3 comprises a support rod 31 and a drive rod 32, wherein the support rod 31 is hinged with the drive rod 32; alternatively, the middle portion of the support rod 31 is hinged to the middle portion of the driving rod 32, and further, the specific hinge point of the support rod 31 to the driving rod 32 is determined by the size between the first support 1 and the second support 2. For example, when the area of the first support 1 is smaller than that of the second support 2, in order to prevent the support rod 31 from being detached from the second support 2, a stopper may be provided on the second support 2, or the distance between the hinge point and the second support 2 may be smaller than the distance between the hinge point and the first support 2.
One end of the support rod 31 is hinged with the second support member 2, and the other end is connected with the first support member 1 in a sliding manner;
One end of the driving rod 32 is fixedly connected to the rotating shaft 4, and the other end of the driving rod 32 is slidably connected to the second support member 2, so that the driving rod 32 applies a force to the second support member 2 in a direction away from the first support member 1 during rotation, thereby lifting the second support member 2. Specifically, the driving rod 32 may be fixedly connected with the rotating shaft 4, and may also be in a key connection manner, a spline connection manner, or the like. Alternatively, the center line of the driving lever 32 is perpendicular to the center line of the rotation shaft 4.
When the lifting device is used specifically, referring to fig. 2 and fig. 3, when the lifting device needs to be lifted, the driving part 5 drives the rotating shaft 4 to rotate, the driving rod 32 is driven by the rotating shaft 4 to rotate around the central line of the rotating shaft 4, and the rotating shaft 4 is controlled to rotate along the direction capable of increasing the distance between the first supporting part 1 and the second supporting part 2. For example, when the center line of the rotating shaft 4 is parallel to the first support 1 and the center line of the driving lever 32 is perpendicular to the center line of the rotating shaft 4, the rotating direction of the rotating shaft 4 is from a state parallel to the first support 1 to a state perpendicular to the first support 1. When the foldable box is folded, the driving member 5 drives the rotating shaft 4 to rotate in the opposite direction, that is, the rotating shaft 4 rotates in a direction capable of reducing the distance between the first support member 1 and the second support member 2, for example, when the center line of the rotating shaft 4 is parallel to the first support member 1 and the center line of the driving rod 32 is perpendicular to the center line of the rotating shaft 4, the rotating direction of the rotating shaft 4 rotates from a state perpendicular to the first support member 1 to a state parallel to the first support member 1. Since the driving rod 32 is driven to rotate by the rotation of the rotating shaft 4, the driving member 5, whether it is a motor, a hydraulic cylinder or an air cylinder, will not increase the dimension in the direction perpendicular to the first supporting member 1 by a large margin, because: when the driving member 5 is a motor, the driving rod 32 is driven to rotate by a transmission member, and the size of the driving member in the direction perpendicular to the first supporting member 1 is only the size of the motor; when the driving member 5 is a hydraulic cylinder or an air cylinder, the hydraulic cylinder or the air cylinder is inclined, and the size of the hydraulic cylinder or the air cylinder in the direction perpendicular to the first supporting member 1 is far smaller than the size of the length of the air cylinder body, so that the space occupied by the lifting device in the direction perpendicular to the first supporting member 1 can be greatly reduced.
