Description

Telescopic device and box with multi-directional telescopic function

The present invention is a "telescopic device and a box with multi-directional telescopic function", and relates to a technical field that allows the volume of the box to be increased or decreased as needed.

In recent years, in line with the evolution of Internet technology and online shopping, coupled with the epidemic situation, online shopping provides consumers with a quick shopping method without going out. Nowadays, many people choose to pick up the goods at the supermarket and pay at the same time when shopping online. Most of the goods from manufacturers will be sent to the central warehouse of supermarkets first, and then transferred to various stores using the logistics system. In the early days of logistics, cartons were used for transportation. After a single delivery, the cartons were no longer used and were handed over to resource recycling companies for recycling. However, due to the significant increase in the cost of raw materials in recent years, and the recycling of many materials, the improved method is to use Reusable rigid logistics boxes for transportation. Most of the existing logistics boxes are made of fixed volume. In actual use, if the total volume of the goods in the store is larger than the volume of a single box, there will be troubles that it cannot be loaded. Although enlarging the logistics box can solve this problem, if the box is too large and the goods inside are not fully loaded, the wasted storage space will still make the transportation of the logistics vehicle difficult. Benefits are reduced.

Obviously, the existing fixed-volume box structure used in logistics is still not ideal and perfect, and there is a need for improvement.

In view of this, the inventor specially researched and created this case, hoping that through the proposal of this case, the shortcomings of the existing fixed volume logistics box can be improved, and the function of the logistics box can be more perfect and ideal to meet actual needs.

In order to improve the above-mentioned conventional fixed-volume logistics boxes, which have shortcomings that are not conducive to proper adjustment of the optimal volume, the main purpose of the present invention is to provide a "telescopic device and a box with multi-directional telescopic function", which can be used for logistics or storage. The object box can be reused to reduce costs and losses; the telescopic device has multi-stage extension adjustment and positioning functions, and when the one-way extension reaches the end, the return design of the structure can be used to release the one-way restriction and return to the starting point of shortening condition. When the telescopic device is applied to a logistics box, the volume of the box can be changed arbitrarily, so that the volume of the box can be adjusted at any time according to the quantity or size of the goods to meet actual logistics loading requirements.

The secondary purpose of the present invention is to provide a "telescopic device and a box with multi-directional telescopic function". Since the box can change its volume arbitrarily, when the total volume of the goods to be accommodated is much smaller than the box volume, the box The volume can be reduced, saving the space occupied by transport vehicles, and maximizing the transportation efficiency of logistics vehicles.

Another object of the present invention is to provide a "telescopic device and a box with multi-directional telescopic function". When changing the volume of the box, the box can be stretched, enlarged or collapsed directly with both hands without using tools. Just zoom out, saving time and effort, and the operation is very simple and fast.

In order to achieve the above purpose, the specific method in this case is to use multiple "telescopic devices" to meet the purpose of changing the volume of the box.
