Description

Technical Field

[0001] This utility model belongs to the field of flatbed truck technology, specifically relating to a caster mounting structure for a flatbed truck and the flatbed truck itself. Background Technology

[0002] Currently, casters on flatbed trucks are typically fixed to the bottom of the platform using welding or bolting. While welding ensures high structural strength and stability between the casters and the platform, it also makes repairs difficult when the casters are damaged or require maintenance or replacement. The welded structure is not easily disassembled, and may even necessitate replacing the entire platform, significantly reducing the maintainability and lifespan of the equipment.

[0003] On the other hand, for ease of assembly and disassembly, some flatbed trailers use bolts to secure the casters to the underside of the platform. However, this type of structure typically requires four sets of bolts for each caster, totaling sixteen sets for a standard flatbed trailer with four casters. These bolts penetrate the upper surface of the platform and run through it, resulting in a large number of exposed metal bolt heads on the front of the platform. This not only affects the overall neatness and aesthetics but also makes the bolts prone to corrosion in humid or corrosive environments. Once the bolts rust, subsequent disassembly and replacement become extremely difficult, thus diminishing the ease of maintenance that this structure was originally intended to offer. Utility Model Content

[0004] In view of the various shortcomings of the existing technology, a caster mounting structure for a flatbed truck and a flatbed truck are proposed to solve the deficiencies of the existing technology in terms of structural stability, maintainability and appearance design.

[0005] To achieve the above objectives, this utility model provides the following technical solution: In a first aspect, this utility model provides a caster mounting structure for a flatbed truck, including a mounting base and a connecting member. The mounting base is rotatably connected to the caster. The flatbed truck has a mounting groove that engages with the mounting base. The connecting member has a limiting block protruding from its body. The connecting member passes through the flatbed truck and the mounting base in sequence, and the limiting block abuts against the mounting base.

[0006] The technical solution is further configured such that a limiting plate is provided on a set of opposite groove walls of the mounting groove, the limiting plate being parallel to and spaced apart from the vehicle plate to form a space for accommodating the mounting seat.

[0007] The technical solution is further configured such that a slot is provided on another set of opposite walls of the mounting groove.

[0008] The technical solution is further configured such that the limiting plate is provided with a limiting hole that matches the shape of the connecting body.

[0009] The technical solution is further configured such that the top surface of the vehicle panel is recessed to form a recessed portion, the recessed portion is correspondingly provided with the mounting groove, and the bottom surface of the recessed portion is provided with a first mounting hole through which the connecting body and the limiting block pass.

[0010] The technical solution is further configured such that the top of the connector is flush with the bottom surface of the recess.

[0011] The technical solution is further configured such that the mounting base is provided with a second mounting hole that is adapted to the shape of the connector body.

[0012] Secondly, this utility model provides a flatbed vehicle, including a platform, on which the aforementioned caster mounting structure is provided.

[0013] The technical solution is further configured such that the edge of the vehicle panel is provided with interlocking concave and convex components to enable splicing of multiple vehicle panels.

[0014] The beneficial effects of this utility model are: 1. By setting up mounting bases and mounting slots, the mounting bases and casters can be inserted into the mounting slots and then fixed by connecting parts. The structure is stable and easy to disassemble and maintain. It completely eliminates bolt connections and fundamentally eliminates the problem of difficult disassembly caused by bolt corrosion. It is especially suitable for humid or corrosive environments.

[0015] 2. The connector is located on the bottom of the recess, which greatly improves the aesthetics of the vehicle body. At the same time, the connector will not come into contact with the transported object during transportation, thus avoiding interference. Attached Figure Description
