Technical Field

[0001] This utility model relates to the field of trolley technology, specifically to a foldable three-sided trolley that is easy to use. Background Technology

[0002] A trolley is a piece of equipment used to move and handle goods within a warehouse or logistics center. Trolleys are typically equipped with dividers to separate them into at least two holding spaces so that different types of goods can be placed separately.

[0003] The existing three-sided trolleys on the market use two side panels to support the weight of the products stacked at the bottom. This can cause the outer frame of the side panels to deform easily. In addition, when folding existing products, the folding position is often determined by folding one side panel and fixing the other side. This results in relatively large space occupation, poor stability, and inconvenience for assembly. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an easy-to-use foldable three-sided trolley to solve the problems mentioned in the background section. Existing three-sided trolleys on the market use two side panels to support the weight of products stacked at the bottom, which can easily lead to deformation of the outer frame tubes of the side panels. Moreover, when folding existing products, the folding position is often determined by folding one side panel and fixing the other side, which results in relatively large space occupation, poor stability, and inconvenience in assembly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a user-friendly foldable three-sided trolley, comprising a base frame, characterized in that: an angle iron is fixedly welded inside the base frame; a base plate is provided on the base frame; a lock is provided at the bottom of the base plate; a first guardrail is provided at the rear end of the base frame; caster plates are fixedly installed on both sides of the bottom of the first guardrail; connecting grooves are fixedly installed on the inner end surfaces of the caster plates; a first swivel wheel is fixedly installed at the bottom of the caster plate; a brake plate is provided inside each of the first swivel wheels; two connecting plates are fixedly installed at the bottom of the first guardrail; and second swivel wheels are fixedly installed on both sides of the bottom of the base frame; a brake plate is provided inside each of the second swivel wheels.

[0006] By adopting the above technical solution, the second guardrail is folded inward towards the first guardrail through the hinge between the second guardrail and the first guardrail, thereby reducing the space occupied by the product when stacked. Then, two rear caster plates are added to the left and right sides of the bottom of the first guardrail. These caster plates can be connected to the base frame during assembly while the first caster is installed, thereby realizing the connection between the first guardrail and the base frame and facilitating product assembly. Then, connecting grooves are provided on the left and right sides of the caster plates, so that the bottom rods of the second guardrail can be inserted into them to limit their position and maintain stability.

[0007] Preferably, a second protective railing is provided on both sides of the base plate, and a plug is provided at the bottom rear end of each of the second protective railings, and the plug is inserted into the connecting groove.

[0008] By adopting the above technical solution, the caster plate has connecting grooves on the left and right sides, which can effectively allow the bottom poles of the second guardrail to be inserted into them to limit their position and maintain stability.

[0009] Preferably, three horizontal strips arranged in a linear array are fixedly installed on both the first and second guardrails. A fixing block is provided at the bottom of the second guardrail near the front end, and a fixing hole is provided in each fixing block. A hinge is provided between the first and second guardrails.

[0010] By adopting the above technical solution, both the first and second guardrails are composed of round tubes with mesh panels added in the middle, and horizontal strips are added in the middle of the mesh panels, thereby increasing the stability of the first and second guardrails.

[0012] By adopting the above technical solution, the load-bearing capacity of the base plate can be improved by the cooperation between the rectangular tube set at the bottom of the base plate and the first reinforcing plate, thereby improving the strength of the base plate. Then, the connection plate set at the bottom of the first guardrail and the connection seat plate at the rear end of the base plate can be connected to improve the stability of the base plate.

[0013] Preferably, a support plate is provided between the second guardrails, and two second reinforcing plates are fixedly installed at the bottom of the support plate, and hooks are fixedly installed at both ends of the support plate.

[0014] By adopting the above technical solution, the hooks at both ends of the support plate are placed on the horizontal strip inside the second guardrail, thereby restricting and supporting the hooks. This makes the support plate more stable and less prone to falling off. Furthermore, the second reinforcing plate at the bottom of the support plate significantly improves its load-bearing capacity.

[0015] Preferably, a rotating seat is slidably installed on the second guardrail, and a connecting rod is rotatably installed inside the rotating seat. The connecting rod is L-shaped, and a positioning block is fixedly installed on the second guardrail. The positioning block has a notch.

[0016] Using the above technical solution, the second guardrail is equipped with a connecting rod, which is L-shaped. Therefore, workers can rotate the rod so that the bent part of the connecting rod is inserted into the notch on the positioning block, thereby restricting the goods and preventing them from falling.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

This easy-to-use foldable three-sided trolley uses hinges between the second and first guardrails to fold the second guardrail inwards towards the first guardrail, thereby reducing the space occupied when the product is stacked. Two rear caster plates are added to the left and right sides of the bottom of the first guardrail. These caster plates can be connected to the base frame during assembly while the first caster is installed, thus connecting the first guardrail to the base frame and facilitating product assembly. Connecting grooves are provided on the left and right sides of the caster plates, which can effectively insert the bottom rods of the second guardrail into them for positioning and stability.

[0019] 2. This easy-to-use foldable three-sided trolley improves the load-bearing capacity and strength of the base plate through the cooperation between the rectangular tube at the bottom of the base plate and the first reinforcing plate. The connection between the connecting plate at the bottom of the first guardrail and the connecting seat plate at the rear of the base plate further enhances stability. When a support plate is needed to separate transported items, the hooks at both ends of the support plate are placed on the horizontal strip inside the second guardrail. This horizontal strip restricts and supports the hooks, ensuring stability and preventing them from falling off. The second reinforcing plate at the bottom of the support plate further enhances its load-bearing capacity. Attached Figure Description
