These features and advantages of the present utility model will be disclosed in detail in the following specific embodiments and accompanying drawings.

【Description of drawings】

Below in conjunction with accompanying drawing, the utility model is further described:

Fig. 1 is the structural representation of the utility model.

【detailed description】

The technical solutions of the embodiments of the present invention are explained and described below in conjunction with the accompanying drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention, not all of them. Based on the examples in the implementation manners, other examples obtained by those skilled in the art without making creative efforts all belong to the protection scope of the present utility model.

Referring to Fig. 1 , there is shown a lifting mechanism of a cargo loading machine, the cargo loading machine includes a frame and a material rack 3, the frame includes a base 1 and a guide frame 2 arranged on the base 1, and the bottom of the base 1 is provided with a ten thousand Direction wheel 11, universal wheel 11 can roll towards multiple directions, can push the frame to walk and transport the goods on the material rack 3 . The lifting mechanism is used to drive the material rack 3 up and down. After the lifting mechanism drives the material rack 3 down, it is convenient to place the goods on the material rack 3. After the lifting mechanism drives the material rack 3 to rise, it is convenient to place the goods on the shelf. The user does not need to go back and forth Squat up and stand up back and forth, reduce labor intensity and improve work efficiency. Specifically, the lifting mechanism includes a screw 41 extending in the height direction and a drive motor 42 for driving the screw 41 to rotate. The center of the rack 3 is provided with a threaded hole 311 matched with the screw 41. There is a guide rod 21, and the material rack 3 is provided with a through hole 312 connected with the guide rod 21, and several guide rods 21 are arranged circumferentially around the screw rod 41. The driving motor 42 drives the screw mandrel 41 to rotate, so that the material rack 3 moves along the axial direction of the guide rod 21 to realize the lifting of the material rack 3; Accurately control the lifting position of the rack 3 to adapt to various racks.

And the lifting mechanism also includes an upper proximity switch 43 and a lower proximity switch 45, the upper proximity switch 43 and the lower proximity switch 45 are connected to the drive motor 42, the upper proximity switch 43 is located at the top of the guide frame 2, and the lower proximity switch 45 is positioned at the lower end of the guide frame 2. The frame 3 is provided with a trigger body 44 for triggering the upper proximity switch 43 and the lower proximity switch 45 . After the trigger body 44 triggers the upper proximity switch 43 or the lower proximity switch 45, the driving motor 42 stops rotating. The lower proximity switch 45 limits the lowest position of the material rack 3, adapts to the working habits of the human body, and does not need to lower one's waist when placing goods; the upper proximity switch 43 limits the highest position of the material rack 3, so as to avoid the driving motor 42 constantly rotating and make the material rack 3 It is stuck with guide frame 2. Preferably, the upper proximity switch 43 and the lower proximity switch 45 are Hall sensors, and the trigger body 44 is a magnet.

And a guide sleeve is installed in the through hole 312, the guide sleeve includes an inner sleeve, an outer sleeve and an elastic body arranged between the inner sleeve and the outer sleeve, the outer sleeve is connected with the assembly hole, the inner sleeve is connected with the guide rod 21, and Balls are arranged on the inner circular surface. When the driving motor 42 is started, the elastic guide sleeve cushions the collision between the material rack 3 and the guide rod 21, reducing the noise and vibration during operation.

In addition, the lifting mechanism can also include an upper support frame connected with the material rack and located above the material rack and a lower support frame connected with the material rack and located below the material rack. The upper support frame and the lower support frame are provided with support sleeves that are threaded with the screw rod . Due to the long length of the screw rod, when the screw rod rotates, the middle part of the screw rod will bend and shake, which will reduce the fluency of lifting and lowering. Therefore, the supporting sleeves of the upper support frame and the lower support frame provide auxiliary support to the screw rod, so as to improve the working performance of the lifting mechanism.

Through the above embodiments, the purpose of the utility model has been fully and effectively achieved. Those familiar with this technology should understand that the utility model includes but is not limited to the contents described in the accompanying drawings and the above specific embodiments. Any modifications that do not deviate from the functional and structural principles of the present utility model shall be included in the scope of the claims.
