[0033] Example 1

[0034] Reference Figures 1-5 A lifting platform for cargo is provided, including a main component 100; it includes a cargo platform 101, which is arranged in a double layer. The four opposite corners of the cargo platform 101 are solid structures, thereby fixing the double-layered cargo platform 101 into one piece. The sides and bottom of the cargo platform 101 are formed into cavities. A support rod 102 is provided inside the cargo platform 101 and is fixedly installed on the inner bottom of the cargo platform 101.

[0035] Specifically, a prefabricated plate 103 is fixedly installed on the top of the support rod 102. A magnetic groove 104 is provided on the top of the prefabricated plate 103. A ball bearing 105 is magnetically attracted to the inner side of the magnetic groove 104. The magnetic groove 104 plays a role in limiting and fixing the ball bearing 105, preventing the ball bearing 105 from shifting due to shaking during transportation of the cargo platform 101.

[0036] The ball bearing 105 protrudes from the horizontal surface of the cargo platform 101. When the cargo slides, it will come into contact with the ball bearing 105, thereby causing the ball bearing 105 to roll. The inner side of the prefabricated tray 103 is conical. Through the conical design, the inner side of the prefabricated tray 103 forms a slope. When the cargo loses contact with the ball bearing 105, under the influence of gravity, the ball bearing 105 will roll along the inner side of the prefabricated tray 103 to the magnetic groove 104 and be fixed.

[0037] Furthermore, a rotating cylinder 106 is rotatably connected to the inner side of the prefabricated tray 103. The number of rotating cylinders 106 is set to multiple, and the multiple rotating cylinders 106 are arranged in a circular array about the vertical center line of the prefabricated tray 103. Through the arrangement of the rotating cylinders 106, when the ball bearing 105 rolls to the surface of the rotating cylinder 106, the friction will cause the rotating cylinder 106 to rotate. Through the arrangement of multiple rotating cylinders 106, when the goods slide, they will drive the ball bearing 105 to contact the rotating cylinder 106 in the same direction, thereby realizing the all-round perception of the sliding signs of the goods.

[0038] Operation process: When the goods slide, they push the ball 105 to move. When the goods continue to slide, the friction will cause the ball 105 to roll. The ball 105 is in close contact with the rotating drum 106, and the friction will drive the rotating drum 106 to rotate. When the goods lose contact with the ball 105, the ball 105 will roll along the inner side of the prefabricated plate 103 to the magnetic groove 104 to be attracted and fixed.

[0039] Example 2

[0040] Reference Figures 3-5 This embodiment differs from the first embodiment in that: a connecting rope 107 is wound around the outside of the rotating drum 106. When the rotating drum 106 rotates due to friction from the ball bearings 105, it will wind up the connecting rope 107. One end of the connecting rope 107 is fixedly connected to an arc-shaped box 108. When the rotating drum 106 winds up the connecting rope 107, it will pull the arc-shaped box 108 to slide. A first spring 109 is provided on the inner side of the arc-shaped box 108. A baffle 110 is fixedly connected to the top of the first spring 109. The baffle 110 and the arc-shaped box 108 are slidably connected.

[0041] The inner side of the cargo platform 101 is provided with an arc-shaped groove 111. The cross-sectional area of ​​the bottom end of the arc-shaped groove 111 is larger than the cross-sectional area of ​​the bottom end of the baffle 110. When the arc-shaped box 108 slides to the arc-shaped groove 111, the baffle 110 is pushed into the arc-shaped groove 111 by the rebound of the first spring 109, and then protrudes out of the surface of the cargo platform 101 to intercept the cargo and prevent the cargo from continuing to slide.

[0042] Specifically, a movable base 112 is fixedly installed at the bottom of the arc-shaped box 108. The movable base 112 is slidably connected to the inner bottom of the cargo platform 101. The movable base 112 supports and limits the arc-shaped box 108, allowing it to slide back and forth. A second spring 113 is fixedly connected to one end of the movable base 112, and the other end of the second spring 113 is fixedly installed at the inner bottom of the cargo platform 101. With the second spring 113, the movable base 112 is initially tightened, causing the baffle 110 to fit against the inner top of the cargo platform 101. When the arc-shaped box 108 slides and the baffle 110 inserts into the arc-shaped groove 111, if the arc-shaped box 108 needs to be reset, the baffle 110 is pressed back into the arc-shaped box 108. After the limit is lost, the movable base 112 is reset by the rebound of the second spring 113.

[0043] The rest of the structure is the same as in Example 1.

[0044] Operation process: When the rotating drum 106 rotates due to friction from the ball bearings 105, it will retract the connecting rope 107. The connecting rope 107 will pull the arc-shaped box 108 to slide. When the arc-shaped box 108 slides to the arc-shaped groove 111, the first spring 109 will rebound and drive the baffle 110 to insert into the arc-shaped groove 111. Then, it will protrude from the surface of the cargo platform 101 to intercept the cargo and prevent it from continuing to slide. By pressing the baffle 110, it will retract into the arc-shaped box 108. After losing its limit, the second spring 113 will rebound and pull the movable base 112 to reset.

[0045] Example 3

[0046] Reference Figures 6-8This embodiment differs from the previous embodiments in that: the protective component 200 includes a toothed rotating cylinder 201 and a trigger plate 202 disposed on the toothed rotating cylinder 201. Both ends of the toothed rotating cylinder 201 are fixedly mounted with bevel gears 203. Multiple toothed rotating cylinders 201 are configured to mesh with each other via the bevel gears 203. Multiple movable bases 112 are also configured, with a toothed rod 114 fixedly mounted on the outer side of the movable base 112 near the edge of the loading platform 101. The toothed rotating cylinder 201 meshes with the toothed rod 114. By providing the toothed rod 114 on the movable base 112 near the edge of the loading platform 101, when the goods slide to the edge of the loading platform 101, the movable base 112... 12 During the sliding process, the toothed rod 114 slides, and the toothed rod 114 drives the toothed rotating cylinder 201 to rotate. The inner side of the toothed rotating cylinder 201 is rotatably connected to the circular tube frame 204. The circular tube frame 204 is fixedly installed at the inner bottom of the cargo platform 101. The circular tube frame 204 is square, and support tubes are welded to the outer sides of the four opposite corners. The support tubes are fixedly installed to the cargo platform 101, so that the circular tube frame 204 is suspended in the middle of the inner bottom cavity of the cargo platform 101, thus providing space for the toothed rotating cylinder 201 to rotate. The circular tube frame 204 plays a supporting and limiting role for the toothed rotating cylinder 201. When one toothed rotating cylinder 201 rotates, it will drive multiple toothed rotating cylinders 201 to rotate through the bevel gear 203.

[0047] Specifically, a positioning post 205 is slidably connected to the inner side of the cargo platform 101. A locking rod 206 is engaged with the inner side of the positioning post 205. A lever 207 is hinged to one end of the locking rod 206. The locking rod 206 is through-type with the cargo platform 101. The lever 207 is hinged to the inner side of the cargo platform 101. A third spring 208 is fixedly connected to one side of the lever 207. One end of the third spring 208 is fixedly installed on the inner side of the cargo platform 101. The lever 207 and the trigger plate 202 are arranged in a one-to-one correspondence. In a corresponding configuration, when the rack 114 drives the toothed drum 201 to rotate, the trigger plate 202 will contact the paddle 207. The bottom end of the paddle 207 is arc-shaped and inclined. Due to the arc and inclined configuration, the trigger plate 202 will first contact the tail end of the paddle 207. While pressing the tail end of the paddle 207, the front end of the paddle 207 will be raised, thereby driving the locking rod 206 to retract. The paddle 207 is raised so that the locking rod 206 loses its engagement with the positioning post 205, thus disengaging.

[0048] Furthermore, the cargo platform 101 is provided with a wave spring plate 209 on its inner side, and a positioning post 205 is set above the wave spring plate 209. A prefabricated frame 210 is fixedly installed on the outer side of the positioning post 205, and a protective net 211 is provided on the inner side of the prefabricated frame 210. When the positioning post 205 is disengaged from the locking rod 206, it rebounds through the wave spring plate 209, thereby pushing the positioning post 205 to rise, so that the protective net 211 extends out to form protection and prevent the goods from falling.

[0049] The rest of the structure is the same as in Example 2.

[0050] Operation process: When the goods slide to the edge of the loading platform 101, the movable base 112 drives the toothed rod 114 to slide during the sliding process. The toothed rod 114 drives the toothed rotating cylinder 201 to rotate. When one toothed rotating cylinder 201 rotates, it will drive multiple toothed rotating cylinders 201 to rotate through the bevel gear 203. When the trigger plate 202 contacts the tail end of the paddle 207, the front end of the paddle 207 will be lifted. The lifting of the paddle 207 will cause the locking rod 206 to lose its engagement with the positioning post 205 and thus disengage. After losing its restraint, the wave spring plate 209 will rebound, thereby pushing the positioning post 205 to rise, causing multiple protective nets 211 to extend and form a fence to prevent the goods from falling.
