[0022] The utility model provides the following description with reference to the accompanying drawings to help fully understand the various embodiments of the utility model as defined by the claims and their equivalents. The description includes various specific details to help understanding, but these details should be regarded as exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the utility model.

[0023] In the description of the present invention, descriptions of orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0024] It will be understood that when one element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.

[0025] The embodiment of the utility model provides a lifting mechanism capable of positioning a tray, such as Figure 1-3 As shown, it includes a cargo platform 200 and a pallet 700. The cargo 10 is used to be placed on the pallet 700, and the pallet 700 is used to be placed on the top surface of the cargo platform 200, so as to drive the cargo 10 to move as the cargo platform 200 rises and falls. The top surface of the cargo platform 200 is provided with a plurality of positioning posts 210 extending upward, and the bottom surface of the pallet 700 is provided with a plurality of positioning holes 710 adapted to the positioning posts 210. Specifically, the position, number and size of the positioning holes 710 can correspond to the position, number and size of the positioning posts 210, respectively, so that each positioning post 210 has a positioning hole 710 adapted thereto. When the pallet 700 is placed on the top surface of the cargo platform 200, the positioning posts 210 are inserted into the positioning holes 710 adapted thereto, and the pallet 700 is positioned by the cooperation of the positioning posts 210 and the positioning holes 710, so that the pallet 700 can be placed in the correct position on the cargo platform 200 every time, which is convenient for the subsequent handling of the pallet 700.

[0026] In some embodiments, the positioning hole 710 includes an introduction portion 711 and a positioning portion 712, the positioning portion 712 is located above the introduction portion 711, and the positioning portion 712 is connected to the introduction portion 711. In the direction of downward extension, the aperture of the introduction portion 711 gradually increases. The larger aperture of the introduction portion 711 makes it easier for the positioning column 210 to be inserted into the introduction portion 711. At the same time, the introduction portion 711 will play a certain guiding role for the positioning column 210. When the positioning column 210 is not aligned with the positioning portion 712, under the action of the gravity of the tray 700, the positioning column 210 will slide on the inner wall of the introduction portion 711, thereby guiding the positioning column 210 to be finally inserted into the positioning portion 712. This structure reduces the difficulty of aligning the positioning column 210 with the positioning hole 710, making it easier for the positioning column 210 to be inserted into the positioning hole 710.

[0027] In some embodiments, a placement groove 220 is further provided on the top surface of the cargo platform 200, and a positioning protrusion 720 adapted to the placement groove 220 is provided on the bottom of the pallet 700. When the pallet 700 is placed on the top surface of the cargo platform 200, the positioning protrusion 720 is embedded in the placement groove 220, so as to further position the pallet 700 through the cooperation between the positioning protrusion 720 and the placement groove 220, thereby further ensuring that the pallet 700 can be placed in the correct position on the cargo platform 200.

[0028] Furthermore, the placement groove 220 penetrates the cargo platform 200 in the front-to-back direction, and the two side walls of the placement groove 220 will move from the left and right limiting positioning protrusions 720 to position the pallet 700 in the left and right directions. At the same time, when a four-way truck or a forklift places the pallet 700 on the cargo platform 200, the placement groove 220 can avoid the fork arms of the four-way truck and the forklift, so that the pallet 700 can be smoothly placed on the cargo platform 200.

[0029] Furthermore, the cargo platform 200 includes two support blocks 230 located on the top thereof, the two support blocks 230 both extend in the front-rear direction, a placement slot 220 is formed between the two support blocks 230, and both sides of the pallet 700 are placed on the top surfaces of the two support blocks 230, so that the pallet 700 is supported by the two support blocks 230. Positioning posts 210 are provided on the top surfaces of the two support blocks 230, and the positioning posts 210 on the top surfaces of the two support blocks 230 can be used to position the pallet 700.

[0030] In some embodiments, the support block 230 can slide in the front-to-back direction, and a locking member is provided on the support block 230. When the two support blocks 230 slide in the rear direction synchronously, the placement position of the tray 700 in the front-to-back direction can be adjusted. After the position is adjusted, the locking member is used to lock and fix the support block 230 so that the support block 230 cannot slide in the front-to-back direction, and is thus fixed in the adjusted position. When the position of the support block 230 needs to be adjusted, the locking member releases the locking of the support block 230.

[0031] Furthermore, the cargo platform 200 includes two guide rails 240 located at the top thereof, both extending in the front-rear direction, and the two support blocks 230 are respectively slidably matched with the two guide rails 240, so that the support blocks 230 can slide in the front-rear direction. The surface of the support block 230 is provided with a threaded hole penetrating therethrough, and the locking member is a bolt threadedly connected to the threaded hole. By screwing the bolt, the length of the bolt extending into the threaded hole changes. When the bolt abuts against the guide rail 240, a large friction force is generated between the bolt and the guide rail 240, so that the bolt can lock and fix the support block 230 on the guide rail 240. When the bolt is separated from the guide rail 240, the bolt no longer locks and fixes the support block 230.

[0032] In some embodiments, a positioning member 750 is provided at the bottom of the pallet 700, and a sensor 250 for detecting the positioning member 750 is provided at the top of the cargo platform 200. The sensor 250 will detect the positioning member 750 only when the pallet 700 is placed at the correct position on the cargo platform 200. If the position where the pallet 700 is placed on the cargo platform 200 deviates greatly from the correct position, the sensor 250 will not detect the positioning member 750. Thus, the sensor 250 can be used to determine whether the position where the pallet 700 is placed on the cargo platform 200 is correct. The sensor 250 may be a photoelectric sensor, and the positioning member 750 may be a corresponding reflective plate.

[0033] The terms and words used in the above description and claims are not limited to the literal meanings, but are only used by the applicant to enable a clear and consistent understanding of the utility model. Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the utility model is provided only for illustration, and not for limiting the utility model as defined by the attached claims and their equivalents.
