[0032] like Figure 1 As shown, the bracket preferably includes an L-shaped frame, which is composed of a flat plate 1 and a vertical plate 2 fixedly connected at right angles. A right-angled plate 3 is fixedly connected between the flat plate 1 and the vertical plate 2. The flat plate 1, the vertical plate 2 and the right-angled plate 3 form a reciprocating drive space. The bracket realizes the installation and arrangement of various components, forming a compact integrated layout and effectively utilizing the assembly space.

[0033] like Figure 3 As shown, preferably, the lifting block 6 is a right-angled trapezoid, the inclined waist of the right-angled trapezoid forms an inclined lifting surface, the upper base of the right-angled trapezoid forms a top plane connected to the inclined lifting surface, and the vertical waist of the right-angled trapezoid forms a connecting surface. The right-angled trapezoid forms a sliding connection with the plate 1 through the lower base.

[0034] like Figure 1 and 2 As shown, preferably, a reciprocating drive 4 is mounted on the plate 1 via a support. The reciprocating drive 4 is arranged outside the reciprocating drive space along the X-axis. The telescopic rod of the reciprocating drive 4 is fixedly connected to the connection surface of the lifting block 6 via the connecting plate 5.

The telescopic rod of the reciprocating drive 4 is perpendicular to the connecting plate 5, which is perpendicular to the lifting block 6. The lifting block 6 is parallel to the reciprocating drive 4.

[0035] Preferably, the reciprocating drive 4 is any one of a pneumatic cylinder, a hydraulic cylinder, and an electric push rod.

[0036] like Figure 1 As shown, preferably, the guide slide assembly includes a guide rail 7 fixed to the inner wall of the riser 2, and the guide rail 7 is arranged along the X direction. A slider 8 is fixed to a side wall of the lifting block 6, and the slider 8 engages with the guide rail 7 to form a guide slide connection. When the reciprocating drive 4 drives the lifting block 6 to reciprocate, the lifting block 6 slides along the guide rail 7 via the slider 8, thereby achieving guidance and stability of the translation.

[0037] Preferably, a guide hole is provided in the horizontal panel of the right-angle plate 3.

[0042] How this compact lifting device works:

[0043] 1. Lifting operation:

[0044] Start the reciprocating drive 4 to retract the telescopic rod, and synchronously drive the lifting block 6 to approach the roller 11, so that the roller 11 gradually rolls from the flat plate 1 to the inclined lifting surface of the lifting block 6, and gradually raises the height of the guide column 9 and the platform 10 through the inclined lifting surface until the roller 11 rolls to the top plane of the lifting block 6, and the platform 10 lifts the product to the highest position.

[0045] 2. Descending operation:

[0046] Start the reciprocating drive 4 to extend the telescopic rod, and synchronously drive the lifting block 6 to gradually separate from the roller 11, so that the roller 11 rolls from the top plane of the lifting block 6 to the inclined lifting surface, and gradually lowers the height of the guide column 9 and the platform 10 through the inclined lifting surface until the roller 11 rolls onto the flat plate 1, and the platform 10 carries the product to the lowest position.
