Description

Technical Field

[0001] This utility model relates to the field of logistics equipment technology, and more specifically to a quick-assembly roller and its carrier. Background Technology

[0002] In the fields of logistics warehousing and cargo transfer, wheeled vehicles are widely used due to their ease of movement. Traditional vehicles typically have wheels fixed to the base using bolts or welding, which presents the following significant drawbacks: (1) Low installation efficiency: Roller installation requires multiple people to work together to use tools to tighten bolts, and the installation of a single set of rollers takes a lot of time; frequent disassembly and assembly can easily damage the bolt threads, leading to increased maintenance costs.

[0003] (2) Poor load expandability: The number of rollers at the corners of the base is fixed, and it is impossible to dynamically increase the support points according to the weight of the goods. When transporting heavy goods, it is often necessary to replace the entire base or customize special equipment, which is not flexible enough.

[0004] (3) High maintenance costs: When a single roller is damaged, the entire bottom structure of the base needs to be disassembled, and even the welding points need to be cut, making the repair process complicated; if bolts are used for connection, disassembly is difficult after corrosion, often leading to premature scrapping of the base.

[0005] Therefore, there is an urgent need for an integrated solution that combines quick installation, adjustable load, and easy maintenance of rollers and base. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a quick-installation roller and its carrier, which greatly improves installation efficiency and has the advantages of lightweight structure, high compatibility, expandable load capacity, and significantly reduced maintenance costs.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A quick-release roller includes a connecting part, a mounting bracket, and a roller. The connecting part is provided with a socket, and a snap-fit ​​mechanism is provided on one side of the socket. The mounting bracket is rotatably connected to the connecting part. The roller is mounted on the bottom of the connecting part. The snap-fit ​​mechanism includes a resilient pin assembly, which is mounted on the side of the connecting part and can extend into the socket.

[0008] Furthermore, the resilient pin assembly includes a fixed base, a pin rod, and a spring. The fixed base is installed on the side of the connecting part and has a communicating receiving hole and a through hole. The receiving hole communicates with the insertion hole. The pin rod includes an insertion rod and a control rod. The insertion rod is located in the receiving hole and can extend into the insertion hole. One end of the control rod passes through the through hole and extends into the receiving hole to connect with the insertion rod. The spring is located in the receiving hole and is fitted onto the control rod. One end of the spring abuts against the insertion rod, and the other end abuts against the fixed base. A control plate is provided on the outside of the fixed base on the control rod.

[0009] Furthermore, a mounting bracket is provided between the roller and the connecting part, and a braking mechanism is provided on the mounting bracket. The braking mechanism includes a brake frame, which is hinged to the mounting bracket. A snap-fit ​​structure is provided on the mounting bracket. One side of the brake frame can contact and engage with the snap-fit ​​structure, and the other side is provided with a friction structure, which can contact the roller to limit the roller's rolling.

[0010] Furthermore, the connecting part is a first connecting square tube, which is arranged vertically and connected to the mounting bracket. An insertion hole is formed inside the first connecting square tube, and the elastic pin assembly is disposed on the side of the first connecting square tube.

[0011] Furthermore, the connecting part includes a connecting base, on which a second connecting square tube is provided, and an insertion hole is formed inside the second connecting square tube. The elastic pin assembly is provided on the side of the second connecting square tube, and a plurality of mounting brackets and rollers mounted on the mounting brackets are connected to the bottom of the connecting base.

[0012] A carrier including quick-release rollers includes a carrier body and a plurality of quick-release rollers. The top of the carrier body has a plurality of support holes, and support legs are provided at the corners of the carrier body. The sides of the support legs are provided with insertion holes. The plurality of quick-release rollers are respectively provided at the corners of the carrier body, and the support legs at the corners of the carrier body extend into the insertion holes of the quick-release roller connecting parts, and the elastic pin assembly can extend into the insertion holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This utility model solves the problems of cumbersome disassembly and assembly and poor expandability of traditional vehicle rollers through modular quick-assembly design.

[0014] 1. Revolutionary improvement in installation efficiency: The flexible pin assembly enables the rollers to lock with the base support legs with a simple plug, greatly shortening the installation time and eliminating the need for tools or bolts.

[0015] 2. Lightweight structure and high compatibility: The standardized design of the connecting square tube is compatible with various base support leg sizes, and the hollow structure of the square tube reduces the overall weight while ensuring strength.

[0016] 3. Significantly reduced maintenance costs: Any damaged roller can be replaced independently, avoiding the need for complete scrapping; vulnerable parts such as pins and springs adopt an open structure, reducing replacement costs.

[0017] 4. Adjustable load: Various types of connecting parts can be used to reasonably select the number of rollers to adapt to different cargo loads. Attached Figure Description

[0023] Preferably, the elastic pin assembly includes a fixing base 6, a pin rod, and a spring 11. The fixing base 6 is installed on the side of the connecting part 2. The fixing base 6 is provided with a connecting receiving hole 12 and a through hole 13. The receiving hole 12 is connected to the insertion hole 7. The pin rod includes an insertion rod 9 and a control rod 8. The insertion rod 9 is located in the receiving hole 12 and can extend into the insertion hole 7. One end of the control rod 8 passes through the through hole 13 and extends into the receiving hole 12 and is connected to the insertion rod 9. The spring 11 is located in the receiving hole 12 and is fitted onto the control rod 8. One end of the spring abuts against the insertion rod 9, and the other end abuts against the fixing base 6. A control piece 10 is provided on the outside of the fixing base 6 for the control rod 8. Specifically, the insertion rod 9 of the pin rod automatically extends into the insertion hole 7 under the preload of the spring 11. The spring 11 can be compressed by pulling the control rod 8 outward through the control plate 10 to unlock it. This allows the insertion rod 9 to cooperate with the insertion hole of the support leg to form a mechanical interlock. Disassembly and assembly can be completed simply by pulling the control plate 10, without tools. It has the advantages of quick one-handed operation, self-locking anti-disengagement, and compact structure.

Specifically, when the brake bracket 5 is pressed down around the hinge point, the friction structure 15 (such as a rubber pad) presses against the surface of the roller 4. At the same time, after pressing down, the other end of the brake bracket 5 contacts and engages with the snap-fit ​​structure 14 to lock and fix the position of the brake bracket 5.

[0025] Preferably, the mounting frame 3 is provided with a rotating structure, one end of which is connected to the mounting frame 3 and the other end is connected to the connecting part 2, so that the roller 4 can rotate in all directions.
