Abstract

Traditional carts cannot hold items of different sizes and shapes when transporting items. This invention provides a cart with retractable pegs on the surface, which can conveniently form a fence around the perimeter when placing items to achieve the function of fixing items.

Description

Retractable trolley structure for fixed items

This creation relates to the technical field of a cart, specifically a cart whose surface is covered with retractable pegs. When items are to be transported, the contact pegs can be pressed, and the pegs outside the area that is not pressed form a columnar fence to secure the items. function, and can be easily placed, taken out and transported.

The trolley is a device widely used in logistics, storage and transportation. However, the fixation of items on traditional carts has always been an important issue during transportation. In order to transport items of different shapes and sizes, telescopic fixing ropes are usually used to fix the items on the cart. However, if the shape of the items is non-flat, more ropes will be required to be fixed in a complicated binding method to prevent the items from rolling, or more ropes must be added. Flat boxes hold and then secure the boxes, thus increasing the difficulty and cost of transportation. In order to solve the transportation demand limitations of transportation and adapt to the shape of different items. Therefore, a new cart design is needed to improve the flexibility and convenience of operation and to facilitate the fixation of items on the cart.

In view of this, the author of this article has made detailed design and careful evaluation of the above-mentioned problems, and finally achieved a truly functional creation.

The purpose of this creation is to provide an innovative cart design with cloth on the surface of the cart. Fully retractable pegs allow for easy placement and fixation of items when operating the cart, while also enabling safe movement of the retractable cart structure.

This creation includes the following main structures and functions. The cart body includes a load-bearing plate, at least one hole panel, a plurality of pegs, a plurality of springs and a bottom plate. One end of the plurality of pegs is connected to a telescopic spring and is fixed to the bottom plate. , and penetrates the load-bearing plate and the hole panel. When no object is placed, due to the action of the spring, multiple retractable pegs protrude from the load plate of the cart. When items are placed, the weight of the items can compress these pegs and then compress the springs, causing the springs to drop close to the position of the load-bearing plate. The uncompressed pegs remain in their original positions, thus forming a barrier to secure the items and ensuring that the items are not damaged during transportation. Shake or slip.

This creation is suitable for various carts that transport, store and deliver different items, such as warehouses, factories, logistics centers, etc. Compared with traditional carts, the present invention has the following advantages: the retractable pegs provide an area for placing and taking out items that can be adjusted according to the shape of the items, and can achieve the function of fixing items without adding ropes or packing, ensuring the safety of items during transportation. Stability. In addition, the device is reusable and environmentally friendly.

Figure 2 is a schematic diagram of this creation operation.

Please refer to Figure 1. This invention is a retractable trolley structure for fixing items, including a trolley body (1), a load-bearing plate (2), a hole panel (3), and a plurality of pegs (4 ), multiple springs (5), and a bottom plate (6).

The embodiment includes that the main structure of the cart body (1) includes a load-bearing plate (2) that can bear To carry items, there is a parallel hole panel (3) below the load-bearing plate (2). There are multiple holes on the load-bearing plate (2) and the hole panel (3). The upper and lower holes are parallel to each other, and there is a peg on the parallel hole. (4), the bolt (4) is connected to the spring (5) below, and the spring (5) is connected to the bottom plate (6). When there is no load, the bolt (4) protrudes from the load-bearing plate (2) due to the action of the spring. When moving items with a cart, place the items on the load-bearing plate (2) because its weight will compress the corresponding pegs (4). The pegs (4) press the springs (5) downwards without touching the items. The pegs (4) remain in a protruding position and therefore form a barrier to prevent the item from shaking, shifting and falling during transport.
