Multi-point supporting and limiting drawer trolley

Abstract

This application discloses a drawer trolley with multi-point support and limiting, comprising: a trolley body, slide rails, and multiple shelves. Each shelf includes a base frame and multiple positioning blocks. The positioning blocks are spaced apart on the base frame along the length of the trolley body, and each positioning block has several limiting notches arranged along the width of the trolley body. When a panel is placed, it can be simultaneously limited in the corresponding limiting notches of different positioning blocks. The simultaneous support and limiting of the end and middle of the panel is achieved through the cooperation of the positioning blocks arranged in the length direction and the limiting notches extending in the width direction. When a long panel is placed, the end and middle of the panel can be simultaneously limited in the corresponding notches of different positioning blocks, achieving simultaneous support and limiting in both length and width directions, preventing bending and deformation, and ensuring flat and intact storage. Furthermore, multiple slide rails are vertically distributed on both sides of the trolley body, and the slide rails on both sides of the shelves are fixed to the base frame by locking devices and slide in cooperation with the slide rails, allowing the shelf position to be flexibly adjusted according to the height of the long panel.

Description

Technical Field

[0001] This utility model particularly relates to a drawer trolley with multi-point support and limiting. Background Technology

[0002] In industrial production and various construction scenarios, the storage and transportation of sheet metal is a crucial link. However, traditional sheet metal storage devices have many limitations and cannot meet the needs of modern, efficient production and management.

[0003] Most common panel storage devices on the market currently employ a two-end support structure, with the core principle being to limit the panel's position using simple slots or baffles. While this design appears simple and practical, it has significant drawbacks. First, for longer panels, the lack of effective support in the middle, relying solely on the support at both ends, makes them prone to bending and deformation under their own weight. This not only affects the panel's appearance but may also lead to a decrease in dimensional accuracy, creating a chain reaction of negative effects on subsequent processing and assembly, increasing scrap rates and production costs. Second, existing devices have a relatively singular limiting direction, typically only constraining the panel in one direction, failing to effectively limit both longitudinal and lateral displacement simultaneously. During transportation, bumps and swaying of the trolley or even minor unevenness in the storage area can cause the panel to shift and collide, resulting in surface scratches, edge damage, and other issues, severely impacting the panel's quality and usability. In addition, fixed devices are more complicated to install and maintain. Since the connections between their components are often non-removable, if a part is damaged or needs to be replaced, the entire device may need to be extensively repaired or replaced, which undoubtedly increases maintenance costs and repair time. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a drawer trolley with multi-point support and limiting.

[0005] To solve the aforementioned technical problems, this utility model adopts the following technical solution:

[0006] A drawer trolley with multi-point support and limiting, comprising:

[0007] The trolley body has multiple vertically distributed grooves on both sides;

[0008] Multiple shelves are slidably mounted on corresponding slide grooves. Each shelf includes a base frame and multiple positioning blocks. The positioning blocks are spaced apart on the base frame along the length direction of the trolley body. Each positioning block has several limiting notches arranged along the width direction of the trolley body.

[0009] When the plate is placed, it can be simultaneously confined in the corresponding limiting notches of different positioning blocks. The positioning blocks arranged in the length direction and the limiting notches extending in the width direction cooperate to achieve synchronous support and confinement of the end and middle of the plate.

[0010] Preferably, the shelf is provided with slide rails on both sides that slide in conjunction with the slide grooves, and the shelf is connected and fixed to the slide rails by locking members.

[0011] Preferably, the bottom frame includes two parallel fixed frames that extend along the length of the trolley body. The two fixed frames are fixedly connected by at least one connecting rod. The outer side of the fixed frame is provided with the slide rail that slides with the slide groove of the trolley body, and the inner side is provided with the positioning blocks arranged at intervals along the length direction.

[0012] Preferably, the slide rail includes a fixed plate and a guide portion formed by bending the edge of the fixed plate towards the slide groove. When the slide rail is engaged with the slide groove, the guide portion maintains sliding contact with the inner wall of the slide groove.

[0013] Preferably, the locking element is a bolt.

[0014] Preferably, both ends of the connecting rod are integrally formed with the fixing frame.

[0015] The beneficial effects of this utility model are:

[0016] Traditional fixed storage devices suffer from problems such as lack of support in the middle, leading to bending and deformation, and a single limiting direction, making them prone to displacement and collision when storing long plates. This utility model drawer trolley solves these drawbacks through ingenious design. Its shelf base frame has multiple positioning blocks spaced along its length, each with a limiting notch arranged along the width of the trolley body. When a long plate is placed, its ends and middle are simultaneously confined within the corresponding notches of different positioning blocks, achieving synchronous support and limiting in both length and width directions. This provides stable support for the middle of the plate, preventing bending and deformation, and ensuring flat and intact storage. Furthermore, multiple vertically distributed sliding grooves are located on both sides of the trolley body. The sliding rails on both sides of the shelf are fixed to the base frame by locking devices and slide in cooperation with the sliding grooves, allowing for flexible adjustment of the shelf position according to the height of the long plate.

[0033] Furthermore, the locking element 5 is a bolt.

[0034] Furthermore, both ends of the connecting rod 23 are integrally formed with the fixing frame 22.
