Description

Technical Field

[0001] This utility model relates to the field of rehabilitation assistive device technology, specifically a foldable anti-tilt wheel bracket. Background Technology

[0002] Electric wheelchairs are upgraded versions of traditional manual wheelchairs by adding high-performance power drive devices, intelligent control devices, batteries, and other components. They are a new generation of intelligent wheelchairs that can be driven by a human-operated intelligent controller to perform multiple functions such as forward movement, backward movement, turning, standing, and lying down. They are high-tech products that combine modern precision mechanics, intelligent numerical control, and engineering mechanics.

[0003] Existing mobility scooters on the market lack anti-roll wheel brackets, which may cause the wheelchair to tip over during movement, posing a certain safety hazard. Even those wheelchairs with anti-roll wheel brackets generally have fixed anti-roll wheel brackets that cannot be folded, which takes up considerable space during packing and transportation, causing many inconveniences. Therefore, those skilled in the art have provided a foldable anti-roll wheel bracket to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a foldable anti-tilt wheel bracket to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A foldable anti-tilt wheel bracket includes a fixing screw, a first fixing plate, a connecting screw, a fixing frame, a second fixing plate, an anti-tilt wheel body, a round tube, mounting screws, and two connecting frames. The fixing frame is connected to the two connecting frames by mounting screws. The first fixing plate and the second fixing plate are mounted with a round tube by the fixing screw. Quick-release pins are installed on the side of the two connecting frames that are close to each other and the side of the first fixing plate and the second fixing plate that are close to each other.

[0007] As a further embodiment of this utility model: the outer surface of the fixing screw is threaded with two positioning nuts, and the outer surface of one of the connecting screws is threaded with a connecting nut.

[0008] As a further improvement of this utility model: the upper surface of the fixing frame is provided with an adjustment hole and the upper surface of the fixing frame is provided with an installation hole.

[0009] As a further improvement of this utility model: an anti-tilt wheel body is connected to the outer surface of the circular tube, and the anti-tilt wheel body is made of rubber.

[0010] As a further improvement of this utility model: the outer surface of the mounting screw is threaded with a mounting nut, and the outer surface of the fixing bracket is coated with an anti-corrosion coating.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This foldable anti-tilt wheel bracket allows for folding operation, significantly reducing its space occupation during idle or transportation periods. This facilitates storage, transport, and handling, improving space utilization and ease of handling, while reducing storage and transportation costs. The rubber anti-tilt wheel body reduces friction wear on the contact surface during use, extending component lifespan. It also provides cushioning, reduces operating noise, and enhances the user experience. Through positioning, connecting, and installing related components, it allows for precise adjustment and stable fixation in multiple positions, adapting to different installation needs and usage environments, thus enhancing the bracket's versatility and adaptability.

[0018] Please see Figures 1-4In this embodiment of the utility model, a foldable anti-tilt wheel bracket includes a fixing screw 1, a first fixing plate 2, a connecting screw 4, a fixing frame 5, a second fixing plate 6, an anti-tilt wheel body 7, a round tube 8, mounting screws 10, and two connecting frames 15. The fixing frame 5 is connected to the two connecting frames 15 by the mounting screws 10. The first fixing plate 2 and the second fixing plate 6 are mounted with the round tube 8 by the fixing screw 1. Quick-release pins 3 are installed on the side of the two connecting frames 15 that are close to each other and the side of the first fixing plate 2 and the second fixing plate 6 that are close to each other. The overall structural design is scientific and reasonable, and has significant practical value and advantages in use. Through the coordinated cooperation of multiple components, it achieves a stable support function, which can effectively improve the anti-tilt performance during equipment use, greatly reduce the risk of equipment tilting and tipping, and provide reliable protection for the safe operation of equipment. It is especially suitable for use scenarios with high stability requirements.

[0019] The outer surface of the fixing screw 1 is threaded with two positioning nuts 9, and the outer surface of one of the connecting screws 4 is threaded with a connecting nut 13. The upper surface of the fixing frame 5 is provided with an adjustment hole 11 and an installation hole 12. This not only makes it convenient for people to assemble the device with the wheelchair, but also makes it convenient for people to fine-tune the installation position of the device.

[0020] The outer surface of the round tube 8 is connected to the anti-roll wheel body 7, which is made of rubber. The outer surface of the mounting screw 10 is threaded with the mounting nut 14. The outer surface of the fixing frame 5 is connected with an anti-corrosion coating, which not only allows people to disassemble and replace the anti-roll wheel body 7, but also prevents the fixing frame 5 from corroding after long-term use.

[0021] The working principle of this utility model is as follows: First, people can initially position the bracket through the mounting holes 12 on the fixing frame 5, and then use the mounting screws 10 to pass through the fixing frame 5 and the two connecting frames 15, and tighten the mounting nuts 14 to complete the fixation of the two.

[0022] Then, the first fixing plate 2, the second fixing plate 6 and the round tube 8 are assembled using the fixing screw 1, and the two positioning nuts 9 are rotated to complete the installation of the anti-tilt wheel body 7.

[0023] When folding is required, pull out the quick-release pin 3, and the two connecting brackets 15 can rotate around the mounting screw 10, which will drive the first fixing plate 2, the second fixing plate 6, the round tube 8, and the anti-tilt wheel body 7 to fold, reducing the space occupied; after folding, insert the quick-release pin 3 to fix it. The anti-corrosion coating on the outer surface of the fixing bracket 5 can prevent the fixing bracket 5 from rusting after long-term use.
