Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The present invention will be further described below with reference to the embodiments.

[0030] In some embodiments, please refer to the appendix to the instruction manual. Figures 1-5 A quick-locking mechanism for a loading platform includes a movable seat 1, a lift 2, and a loading platform 21. The lift 2 is fixedly installed on the top of the movable seat 1, and the loading platform 21 is fixedly installed on one side of the lift 2. A connecting locking mechanism 3 is provided on one side of the loading platform 21 for quickly connecting the loading platform 21 to the vehicle body. The connecting locking mechanism 3 includes a connecting plate 31 slidably installed on one side of the loading platform 21. A locking component 32 for connecting the connecting plate 31 to the vehicle body is provided on one side of the connecting plate 31. A positioning component 33 is provided between the connecting plate 31 and the loading platform 21.

[0031] In this embodiment of the utility model, the loading platform 21 can be quickly connected to the carriage via the connecting plate 31 during use. After connection, the side of the connecting plate 31 that contacts the carriage can be quickly locked by the locking component 32, thereby avoiding shaking or displacement during loading and unloading of goods, improving the connection stability and safety between the loading platform 21 and the carriage. When the connecting plate 31 is not applicable, it can be quickly fixed inside the loading platform 21 by the positioning component 33 to prevent the loading platform 21 from sliding when it moves.

[0032] The loading platform 21 serves as the working surface of the lifting loading platform and is mainly used for the transfer of goods between different heights. The locking component 32 can mechanically lock the connecting plate 31 and the carriage after connection to prevent the platform from shaking or the connection from becoming loose. The positioning component 33 is used to limit the connecting plate 31 inside the loading platform 21 when it is not in use to prevent it from sliding when the platform is moving or not in operation. The above two components have simple structures, are easy to operate, and do not interfere with the normal lifting, transfer or loading functions of the loading platform 21.

[0033] In some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, the locking assembly 32 includes a movable plate 321 rotatably mounted on one side of the connecting plate 31, and an adapter plate 322 rotatably mounted on the other side of the movable plate 321. The adapter plate 322 is T-shaped, and two abutting rods 325 are slidably mounted inside the adapter plate 322. The ends of the two abutting rods 325 that are far apart extend out of the adapter plate 322. A bidirectional screw 326 is rotatably mounted on one side of the adapter plate 322. The surfaces of the two abutting rods 325 are located on one side of the bidirectional screw 326, and the bidirectional screw 326 is threadedly connected to the two abutting rods 325.

[0034] In this embodiment of the utility model, when in use, the connecting plate 31 is first slid out of the loading platform 21, and the connection direction and angle are adjusted by rotating the movable plate 321. Then, the T-shaped adapter plate 322 is inserted into the carriage. When the adapter plate 322 is in contact with the inner wall of the carriage and is flat, the bidirectional screw 326 is rotated so that the two clamping rods 325 slide along the inside of the adapter plate 322 and press against both sides of the inner wall of the carriage, thereby achieving a firm connection, preventing the loading platform 21 from shaking or shifting with the carriage, and improving the stability and safety of the connection.

[0035] A cover plate 323 is provided on the outer side of the adapter plate 322, and the surface of the cover plate 323 is beveled.

[0036] In this embodiment of the utility model, the cover plate 323 covers the outside of the adapter plate 322 and the bidirectional screw 326, which not only serves as a shield to prevent the goods from directly contacting the bidirectional screw 326, but also its inclined surface can provide a transition guide ramp for the goods, making the transition of the goods from the carriage to the loading platform more stable.

[0037] A magnetic block 327 is fixedly installed at the bottom of the cover plate 323, and the magnetic block 327 is magnetically connected to the adapter plate 322.

[0038] In this embodiment of the utility model, the cover plate 323 is quickly connected to the surface of the adapter plate 322 via the magnetic block 327. When the bidirectional screw 326 needs to be adjusted, the cover plate 323 can be quickly removed for adjustment.

[0039] Connecting blocks 324 are fixedly installed on both sides of the movable plate 321, and the connecting blocks 324 are connected to the loading platform 21 through the positioning component 33.

[0040] In this embodiment of the utility model, when the connecting plate 31 is retracted into the loading platform 21, the movable plate 321 rotates and retracts synchronously, and the two connecting plates 31 are quickly positioned with the handle of the loading platform 21 through the positioning component 33.

[0041] In some embodiments, such as Figure 2 , Figure 5 and Figure 6 As shown, the positioning component 33 includes a limiting plate 331 hinged to the surface of the loading platform 21, and a limiting groove 332 is formed on the surface of the connecting plate 31. One side of the limiting plate 331 is slidably connected to the limiting groove 332.

[0042] In this embodiment of the utility model, when the connecting plate 31 is inserted into the loading table 21, the limiting plate 331 can be rotated to allow the limiting plate 331 to fall down and slide into the limiting groove 332 on the surface of the connecting plate 31 to lock the connecting plate 31.

[0043] The limiting plate 331 is set in an L-shape, and one side of the limiting plate 331 extends into the limiting groove 332.

[0044] In this embodiment of the utility model, when the L-shaped limiting plate 331 falls, it can just fix the connecting plate 31 of the loading table 21. If it does not fit the limiting groove 332, it means that the connecting plate 31 has not been fully loaded into the loading table 21.

[0045] A retaining ring 333 is rotatably mounted on one side of the connecting block 324, and an opening 334 is provided on the surface of the retaining ring 333.

[0046] In this embodiment of the utility model, the loading platform 21 is surrounded by support rods. When the connecting plate 31 is retracted, the movable plate 321 can be rotated to bring the two connecting blocks 324 of the movable plate 321 close to the support rods. The corresponding support rods pass through the opening 334 and enter the inside of the retaining ring 333. Then, the retaining ring 333 is rotated to move the opening 334 into the inside of the connecting block 324, thus completing the connection very conveniently.

[0047] In this embodiment of the utility model, during use, the connecting plate 31 is first slid out of the loading platform 21, and the connection direction and angle are adjusted by rotating the movable plate 321. Then, the T-shaped adapter plate 322 is inserted into the carriage. After the adapter plate 322 is in contact with the inner wall of the carriage and is flat, the double-acting screw 326 is rotated, causing the two clamping rods 325 to slide along the inside of the adapter plate 322 and press against both sides of the inner wall of the carriage, thereby achieving a firm connection and preventing shaking or displacement between the loading platform 21 and the carriage. The cover plate 323 covers the outside of the adapter plate 322 and the double-acting screw 326, which not only serves as a shield to prevent the goods from directly contacting the double-acting screw 326, but also provides a transition guide ramp for the goods with its inclined surface. The cover plate 323 is magnetically connected to the outside of the carriage. Block 327 can be quickly connected to the surface of adapter plate 322. When the bidirectional screw 326 needs to be adjusted, the cover plate 323 can be quickly removed for adjustment. When the connecting plate 31 is retracted into the loading platform 21, the limiting plate 331 can be rotated to allow the limiting plate 331 to fall down and slide into the limiting groove 332 on the surface of the connecting plate 31 to lock the connecting plate 31. The loading platform 21 is surrounded by support rods. When the connecting plate 31 is retracted, the movable plate 321 can be rotated to bring the two connecting blocks 324 of the movable plate 321 close to the support rods. The corresponding support rods pass through the opening 334 and enter the inside of the retaining ring 333. Then, the retaining ring 333 is rotated to move the opening 334 into the inside of the connecting block 324, thus completing the connection very conveniently.
