Description

Technical Field

[0001] This utility model relates to the field of wheelchair technology, specifically to a wheelchair front end connecting device. Background Technology

[0002] Existing wheelchair front connector devices are divided into two types: side connections and center connections. The side connection structure has requirements for the wheelchair connection point. It can only be clamped onto the front footrest tube, and the footrest tube must be an unobstructed area. In addition, the footrest tube must be a non-foldable mechanism, which limits the clamping position. At the same time, when the user gets on and off the wheelchair, the legs are restricted by the clamping position on both sides, making it extremely inconvenient. Furthermore, it cannot be used by some patients with outward-spreading legs, making it extremely inconvenient for the user.

[0003] Existing intermediate connection structures are mainly fixed to the bottom of the frame, which is extremely inconvenient during connection, adjustment, and installation. Furthermore, most intermediate structures are not adjustable, and their installation position can only be fixed to the bottom of the wheelchair. Some are also professionally customized, but these are expensive and only available for specific vehicle models. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wheelchair front-end intermediate connection device, comprising a clamping device, a height adjustment device, and an angle adjustment device. These three components constitute the intermediate connection structure between the wheelchair and the front end. The clamping device is equipped with clamping plates, which can be fixed by adjusting the opening size according to the different pipe diameters of different wheelchair models. The clamping device is also equipped with a clamping telescopic rod, which can adjust the spacing between the clamping plates on both sides according to the different widths of different wheelchair models, and is welded to the clamping plates. The clamping device is fixed to both sides of the height adjustment device by clamps, and can be rotated for installation. The height adjustment device is equipped with a height adjustment plate, which can be adjusted up and down according to different clamping positions to ensure the device's height above the ground. The height adjustment plate is equipped with a telescopic fixing component, which can clamp and fix the telescopic inner rod through a telescopic rod clamp. The device's tilt angle can be adjusted according to different installation positions.

[0007] Furthermore, the telescopic inner rod is sleeved onto the telescopic outer rod and connected by screws.

[0008] Furthermore, the angle adjustment device is located at the front end of the height adjustment device.

[0009] Furthermore, the angle adjustment device is equipped with a hook, which adjusts the swing angle of the hook through an angle adjuster.

[0010] This utility model provides a wheelchair front end connecting device. It has the following beneficial effects:

[0011] This wheelchair front-end connector features a telescopic clamping structure and a double-efficiency clamping handle, making it compatible with various wheelchair models. Its external operation ensures convenient use and wide adaptability. The height adjustment mechanism accommodates different wheelchair clamping positions, ensuring the device remains at the correct ground clearance for the front-end connection. External adjustment offers a wide range of settings for user convenience. The telescopic adjustment accommodates users of different body types and features a quick-release function, allowing for independent wheelchair use. Angle adjustment is achieved via a wrench on the outside, eliminating the need for disassembly. The overall structure is simple, offering multi-directional and multi-angle adjustments to perfectly fit various wheelchairs while providing convenient and unobstructed operation.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figure 1-3As shown, this utility model embodiment provides a wheelchair front-end intermediate connection device, including a clamping device 1, a height adjustment device 2, and an angle adjustment device 3; the three constitute the intermediate connection structure between the wheelchair and the front end. The clamping device 1 is provided with clamping plates 11, which can be fixed by adjusting the opening size according to the different pipe diameters of different vehicle models; the clamping device 1 is provided with a clamping telescopic rod 12, which can adjust the spacing between the clamping plates 11 on both sides according to the different widths of different vehicle models, and is welded to the clamping plates 11; the clamping device 1 is fixed to both sides of the height adjustment device 2 by clamps 13, and the clamping device 1 can be rotated 180° for installation; The height adjustment device 2 is equipped with a height adjustment plate 10, which can be adjusted up and down according to the height of different clamping positions to ensure the height of the device off the ground; the height adjustment plate 10 is equipped with a telescopic fixing member 8, which can clamp and fix the telescopic inner rod 7 through the telescopic rod clamp 9; at the same time, the telescopic outer rod 6 is sleeved on the outside of the telescopic inner rod 7 and connected by screws, and the length of the overall device can be adjusted through the mounting holes on the telescopic inner rod 7; the front end of the height adjustment device 2 is equipped with an angle adjustment device 3, which can adjust the tilt angle of the device according to different installation positions; the angle adjustment device is equipped with a hook 4, and the swing angle of the hook 4 can be adjusted by an angle adjuster 5.

[0018] The clamping device 1 is equipped with a clamping plate 11 and a clamping telescopic rod 12.
