Description

Technical Field

[0001] The utility model relates to the technical field of carts, in particular to a multi-layer cart which is convenient to draw and pull. Background Art

[0002] Multi-layer carts are a common storage and transportation tool for short-time, short-distance and large-capacity transportation. They are widely used in various occasions such as commerce, industry and home. They are convenient and practical. In recent years, in order to facilitate users to store and retrieve items on the storage container of the cart and reduce the space occupied by the cart, many businesses have improved the traditional multi-layer carts.

[0003] Some of the existing multi-layer carts have storage containers movably arranged in the storage space of each layer, and some have storage containers arranged to be rotatable to enter and exit the storage space. However, the above-mentioned multi-layer carts have the following problems: in order to facilitate the user to reach out and pull the storage basket / dispensing tray out of the storage space inside the cart, a certain hand accommodation space must be left on the top of each layer of the storage basket / dispensing tray to facilitate the user to reach out and pull the storage basket / dispensing tray to rotate, but this will increase the size of the cart and take up more space. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a multi-layer cart that is easy to pull out, including a storage container with a special structure, which reduces the volume of the frame, saves space and facilitates users to quickly pull out the storage container. The structure is simple and convenient, and the operating experience is good.

[0005] A multi-layer cart that is easy to pull out, characterized in that: it includes a main frame and a plurality of storage containers; the main frame forms a storage space inside, and the storage space includes a plurality of storage units arranged layer by layer up and down; each layer of the main frame is provided with at least one pull-out outlet for the storage container to enter and exit; the storage container is arranged in the storage unit; the storage container includes a first end and a second end distributed in a horizontal direction, and the top of the first end is lower than the top of the second end to form a notch.

[0006] The user can pass his hand through the gap of the storage container, grasp the first end of the storage container, and quickly pull the storage container out of the storage unit to access items or perform cleaning, disassembly, washing, replacement, etc. There is no need to leave additional gaps between layers to accommodate finger pulling, so that the storage containers on each layer are arranged more compactly, further reducing the size of the cart, reducing the occupied space, having a simple and convenient structure, and providing a good user operating experience.

[0007] Furthermore, the main frame includes a base and uprights, the uprights include a first upright and a second upright, the first upright and the second upright are respectively vertically fixed at two opposite end positions on the base, and the storage space is located above the base.

[0008] Furthermore, the vertical poles also include a third vertical pole, which is vertically fixed to the upper end of the base; the first vertical pole, the second vertical pole and the third vertical pole are distributed in a triangular shape. The triangularly distributed vertical poles and the base form a semi-enclosed structure. The cart can only pull out the storage container from the side where the third vertical pole is not provided, and is more suitable for use in places where objects are taken from one side or placed against a wall on one side. In addition, the third vertical pole helps to prevent the storage container from protruding or falling from the side other than the exit, thereby avoiding taking up more space or contaminating the contents in the storage container.

[0009] Furthermore, the main frame includes a plurality of middle plates, and the middle plates are arranged in the storage space to divide the storage space into a plurality of the storage units.

[0010] Furthermore, the second end of each storage container is hinged to the first vertical pole or the second vertical pole. The user can put his hand through the notch of the storage container hinged to the first vertical pole, grasp the first end of the storage container, and pull the storage container to rotate around the second end to make the storage container rotate around the first vertical pole or the second vertical pole to leave the storage unit; similarly, the user can pull the storage container hinged to the second vertical pole in the same way to rotate and swing around the second vertical pole to leave the storage unit, and then take items into or put items into the storage container or clean the storage container. On the one hand, the user can easily pull the storage container to turn to both sides to take out and put items; on the other hand, the user can intuitively judge that the first end of the storage container with a notch should be grasped to rotate around the second end without a notch by observing the position of the notch, without having to first determine which vertical pole the storage containers of each layer are hinged to and then determine the rotation direction of the storage container, which is simple and convenient.

[0011] Furthermore, the second ends of the storage containers located at adjacent layers are staggeredly connected to one of the first and second vertical poles, which is beneficial to the balance of the cart when the storage container is rotated out to take out items; and due to the notch on the storage container, the user can easily identify which end to pull the storage container to rotate and pull it out, which is convenient for operation.

[0012] Furthermore, the adjacent middle plate below each storage container is fixed to the same first vertical pole or the second vertical pole hinged to the storage container.

[0013] Furthermore, the storage container is placed on the middle plate.

[0014] Furthermore, the main frame further comprises a top plate, which is fixed to the top of the first upright pole and can be used to place items.

[0015] Furthermore, the multi-layer trolley based on convenient pulling and pulling also includes a plurality of universal wheels, and the universal wheels are fixedly connected to the bottom of the base, so as to be conveniently used for material transportation or storage between multiple occasions.

[0016] In order to better understand and implement the present invention, the present invention is described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS
