In addition, the hinge point at the high end of the link mechanism is fixedly connected with the top of the cavity 121 through the hinge seat 4, and the hinge point at the low end is fixedly connected with the lifting wheel 3 through the hinge seat 4.

Specifically, one connecting rod 21 close to the hinge point of the low end is provided with a fixing block 22 welded in the horizontal direction, the bottom supporting box 12 is horizontally provided with a positioning pin 123 penetrating into the cavity 121 in a movable manner, and one end of the fixing block 22 far away from the connecting rod 21 is provided with a positioning hole 221 for inserting and matching the positioning pin 123. Meanwhile, the holding block 122 is fixedly welded on the end face, away from the cavity 121, of the positioning pin 123, so that the contact area held by a worker is increased, and the positioning pin 123 is convenient to move. When the lifting wheel 3 extends out of the cavity 121, the positioning pin 123 is inserted into the positioning hole 221; when the lifting wheel 3 needs to be retracted, the positioning pin 123 is pulled out of the positioning hole 221, and the lifting wheel 3 is retracted into the cavity 121. A locking assembly is disposed between the positioning pin 123 and the positioning hole 221, so as to limit the positioning pin 123 from being separated from the positioning hole 221.

Referring to fig. 3, specifically, the locking assembly includes a protrusion 51 welded on the wall of the positioning hole 221, a groove 52 disposed at one end of the positioning pin 123 inserted into the positioning hole 221 along the length direction of the positioning pin 123 for inserting the protrusion 51, and an arc-shaped groove 53 communicated with the groove 52 and disposed along the circumferential direction of the sidewall of the positioning pin 123. The protruding block 51 is disposed in a cylindrical shape, when the positioning pin 123 is inserted into the positioning hole 221, the protruding block 51 is inserted into the groove 52, and when the positioning pin 123 slides to a position where the arc-shaped groove 53 is communicated with the groove 52, the positioning pin 123 is rotated, and the protruding block 51 is rotated and clamped in the arc-shaped groove 53, so that the positioning pin 123 is limited to be separated from the positioning hole 221.

The implementation principle of the embodiment is as follows: when the carton needs to be carried, a worker can stretch the handle into the carrying hole 7 and lift the carton, and the lifting wheel 3 stretches out of the cavity 121 through the link mechanism; the positioning pin 123 is inserted into the positioning hole 221, so that the projection 51 is inserted into the groove 52, when the projection 51 slides to the position where the arc-shaped groove 53 is communicated with the groove 52, the positioning pin 123 is rotated, the projection 51 is clamped and matched with the arc-shaped groove 53, the positioning pin 123 is further limited to be separated from the positioning hole 221, the lifting wheel 3 is kept in a stretching state, a worker pulls the pull rod 61, and the carton can move along with the rolling of the lifting wheel 3.

When the cartons need to be stacked and stored, the positioning pin 123 is rotated in the opposite direction and pulled out of the positioning hole 221, the lifting wheel 3 is retracted into the cavity 121 through the link mechanism, and the bottom surface of the carton is kept flat. The worker takes the pull rod 61 into the receiving groove 62 so that the side walls of the cartons are kept flat, and then the worker carries the cartons up through the carrying holes 7 and stacks them for storage.

Example two:

referring to fig. 4, the difference between the present embodiment and the first embodiment is: the locking assembly is different from the locking assembly, and specifically, the locking assembly includes magnets 54 fixedly mounted on the wall of the positioning hole 221 and engaged with each other when the positioning pin 123 is inserted into one end of the positioning hole 221, in this embodiment, the magnets 54 may preferably be magnets. When the positioning pin 123 is inserted into the positioning hole 221, the positioning pin 123 is restricted from being removed from the positioning hole 221 by the attraction between the magnets 54.

Example three:

referring to fig. 5, the present embodiment is different from the first embodiment in that: the locking assembly is different from the prior art, and specifically, the locking assembly includes a limiting block 55 welded to an end portion of the positioning pin 123 close to the positioning hole 221 and a pressure spring 56 sleeved on the positioning pin 123, and the pressure spring 56 is fixedly connected between the limiting block 55 and a side wall of the supporting bottom box 12. When the pressure spring 56 is in a natural state, the positioning pin 123 is inserted into the positioning hole 221, and the positioning pin 123 is further restricted from being separated from the positioning hole 221. When the limiting block 55 is pressed towards the side wall of the supporting bottom box 12, the pressure spring 56 is in a compressed state, and the positioning pin 123 is pulled out of the positioning hole 221.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
