[0023] See also Figure 3As shown, symmetrically arranged slide grooves are provided on both sides of the top of the base 1, and the bottom of the movable seat 305 is slidably connected to the inside of the slide grooves. The slide grooves and the movable seat 305 are both arranged in an inverted T shape.

[0025] The pushing mechanism 4 also includes a transmission rod B405. A moving groove is provided inside the placing table 306. The transmission rod B405 is rotatably connected inside the moving groove. One end of the transmission rod B405 that passes through the outer side of the moving groove is fixedly sleeved with a bevel gear C406. One end of the screw rod 302 is fixedly sleeved with a bevel gear D407. The bevel gear A403 meshes with the bevel gear D407. The outer wall of the transmission rod A402 is threadedly connected with a push plate 408. When the goods are raised, the screw rod 302 rotates and the synchronous belt The movable bevel gear D407 rotates, so that the bevel gear D407 drives the transmission rod A402 to rotate.

[0026] See also Figure 6 As shown, multiple groups of telescopic rods 508 are fixedly installed between the vertical plate 506 and the support plate 507, and springs A509 are sleeved on the outer sides of the multiple groups of telescopic rods 508. During the folding process, the round rods 511 on each L-shaped rod 510 no longer abut against the stop block 512. At this time, the support plate 507 is reset under the elastic force of the spring A509.
[0027] See also Figure 6 As shown, a support pad is provided at the bottom of the support plate 507, and an anti-slip protrusion is provided at the bottom of the support pad.

The other ends of the two springs B607 are fixedly connected to the inner wall of the straight cylinder 604. The circular plate 606 presses the spring B607 downward, causing the spring B607 to generate an opposite elastic force. The spring B607 has a buffering effect.
[0030] See also Figure 7 As shown, a mounting groove is provided inside the stopper 512, and a spring C608 is fixedly installed inside the mounting groove. The bottom end of the spring C608 is fixedly connected to the top end of the slide plate 601, and the elastic potential energy of the spring C608 facilitates the reset of the slide plate 601, so that the slide plate 601 drives the suction cup 605 to reset synchronously, thereby facilitating the movement of the device.
[0031] See also Figures 1 to 3 As shown, limiting grooves are provided on both sides of the upper surface of the placement table 306, and a plurality of balls are embedded and installed inside the limiting grooves. The balls reduce the friction between the goods and the placement table 306, making the unloading process smoother.
[0032] Working principle: When in use, the device is moved to a designated position, and the motor B502 is started. The motor B502 drives the pinion 503 at its output end to rotate, so that the pinion 503 drives the two racks 504 to move in opposite directions, and the racks 504 drive the two moving plates 505 to move under force, and the two moving plates 505 move away from each other on the mounting plate 501. In the process of the two moving plates 505 moving away from each other, the round rods 511 on the two L-shaped rods 510 are respectively against the inclined surfaces of the stopper 512, and the two moving plates 505 move away from each other. The interaction between the round rod 511 and the stopper 512 drives the L-shaped rod 510 and the support plate 507 to move downward. During the downward movement of the support plate 507, the support plate 507 is guided by the telescopic rod 508 and the spring A509 to move downward and to counteract the supporting ground. The counteracting effect between the support plate 507 and the supporting ground can increase the contact area between the support plate 507 and the ground during the lifting of the goods, thereby ensuring the stability of the lifting platform during the continuous lifting operation and improving the safety of the cargo lifting platform during operation. When the L-shaped rod 510 moves downward, the round rod 511 moves downward with the slide plate 601, and then the slide plate 601 drives the connecting plate 602 to move downward synchronously, the connecting plate 602 drives the sliding rod 603 to move downward, the sliding rod 603 drives the straight tube 604 to move downward, and the straight tube 604 drives the suction cup 605 to move downward, so that the suction cup 605 is adsorbed on the ground, thereby ensuring the stability during the loading and unloading process and avoiding the displacement of the entire device; The goods are placed on the placement table 306, and then the motor A301 is started. The motor A301 drives the screw rod 302 to rotate, and the screw rod 302 drives the two sliding blocks 303 to move toward each other, so that the sliding blocks 303 synchronously drive the moving seat 305 to move through the connecting rod 304, so that the moving seat 305 drives the angle of the support frame 307 to change. Due to the rotation connection of the two support frames 307, the two angle-changing support frames 307 drive the placement table 306 to rise, and then the lifting of the goods can be quickly realized. While the goods are rising, the screw rod 302 drives the two sliding blocks 303 to move toward each other, so that the sliding blocks 303 drive the moving seat 305 to move synchronously through the connecting rod 304, so that the moving seat 305 drives the angle of the support frame 307 to change. When the rod 302 rotates, the bevel gear D407 is driven to rotate synchronously, so that the bevel gear D407 drives the transmission rod A402 to rotate. When the bevel gear B404 is engaged with the bevel gear C406, the transmission rod B405 is driven to rotate through the bevel gear C406, so that the transmission rod B405 drives the push plate 408 to move, thereby using the push plate 408 to push the goods on the placement table 306 to move, so that the goods on the placement table 306 can be quickly loaded and unloaded, thereby reducing the intensity of manual labor and improving the work efficiency of loading and unloading.
[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
