Description

Technical Field

[0001] The utility model relates to the technical field of packaging boxes, in particular to a packaging box with adjustable height. Background Art

[0002] Packing boxes are used to transport or store items. There are many types of packing boxes on the market, among which wooden packing boxes are the most widely used. They are popular in the market because of their simple production, convenient installation, low cost, and good assembly properties.

[0003] However, in actual operation, when a packing box carries a lot of goods, when the goods and the packing box are transported to the destination, it is difficult for a forklift or other means of transportation to transport the packing box and the goods to the destination. At this time, manual labor is required to move the packing box and the goods, which takes a lot of effort to move the packing box, or even makes it impossible to move the packing box; or when the packing box needs to be transferred over a short distance, the packing box is too heavy, and it will cost too much to call a forklift to transfer the packing box. At present, there are methods that add pulleys to the bottom of the packing box to facilitate transportation, but although it is convenient for transportation, it is not easy to fix.

[0004] For example, a packaging box disclosed in Chinese patent CN204161776U has universal wheels slidably connected to the four legs of the box body, which can realize the easy movement of the packaging box without consuming too much manpower and material resources; an air bag is arranged between the steel ball rack and the bottom wall of the box body, and the function of the air bag is to extend or retract the universal wheel into the cavity of the leg, so that when the packaging box needs to be moved, the universal wheel can be extended, and when the universal wheel is not needed, the universal wheel can be retracted into the cavity, so that the four legs can fix the packaging box. The function of packing is that an annular protrusion is provided at the end of the foot column, and the steel ball rack and the annular protrusion form abutment to prevent the universal wheel from sliding out of the foot column; an air bag charging and discharging hole is provided on the foot column, and the air nozzle is arranged at the air bag charging and discharging hole to facilitate the inflation and deflation of the air bag; a buffer pad is also fixedly connected to the foot column, which can reduce the impact force of the foot column on the ground when the air bag is deflated, and effectively protect the entire box body; a reinforcing plate is also fixedly connected between the foot column and the box body to increase the stability between the foot column and the box body and improve the service life of the packaging box.

[0005] However, the height of the packaging box cannot be adjusted, which reduces the practicality of the packaging box.

[0006] For this reason, we urgently need to provide a packing box that can adjust the height. Utility Model Content

The connecting piece 307 is movably connected to the outer surface of the fixing rod 304, and the insertion rod 308 is fixedly installed on the end of the connecting piece 307 away from the fixing rod 304. A positioning hole is provided on the lower end surface of the connecting block 301, and evenly distributed card holes are provided on the outer surface of the support rod 302. The insertion rod 308 passes through the positioning hole and the card holes at different positions, so as to facilitate the fixation of the support rod 302, and then facilitate the fixation of the height of the packaging box 1. Embodiment 2

[0029] On the basis of Example 1: a buffer device is arranged at the bottom of the interior of the packaging box 1, and the buffer device includes a damping rod 401, a buffer spring 402 and a support plate 403. The damping rod 401 is fixedly installed around the bottom of the interior of the packaging box 1, the buffer spring 402 is installed on the outside of the damping rod 401, and the support plate 403 is fixedly installed on the top of the damping rod 401.

[0030] A pushing device is provided on the top of the support plate 403, and the pushing device includes a guide rod 501, an electric push rod 502 and a placement plate 503.
