Abstract
Description
Technical Field
[0001] This utility model relates to the field of wheelchairs, and in particular to a push handle structure and a wheelchair. Background Technology
[0002] With the development of modern society, wheelchairs have greatly facilitated the daily lives of the elderly and disabled. Wheelchairs not only provide mobility for people with limb disabilities and limited mobility, but more importantly, they facilitate family members' movement and care for patients, enabling patients to exercise and participate in social activities. Currently, wheelchairs are equipped with handles on the backrest for easy pushing by caregivers. To facilitate transportation to retail outlets after production, folding wheelchairs have become common in the market. However, most wheelchair handles on the market are fixed to the wheelchair and protrude from the outside. Therefore, when a large number of wheelchairs are produced and need to be transported to retail outlets by truck, the non-removable handles occupy a significant amount of space, reducing the number of wheelchairs transported at a time and greatly increasing transportation costs. Furthermore, the fixed height of existing wheelchair handles makes it difficult to accommodate people of different heights, resulting in a poor user experience.
[0003] Therefore, in view of the shortcomings of existing technology, it is necessary to design a push handle structure and wheelchair to solve the above problems. Utility Model Content
[0004] To overcome the shortcomings of the prior art, the present invention aims to provide a push handle structure and a wheelchair.
[0005] To achieve the above and other related objectives, the technical solution provided by this utility model is: a push handle structure, including a fixed tube, a movable tube, a guide joint, a clamping block, a pad, and a screw. The guide joint is fixedly inserted into the top end of the fixed tube. The guide joint has a guide hole. The movable tube is guided by the guide hole and can be movably inserted into the fixed tube. The guide joint has a mounting groove communicating with the wall of the guide hole. The clamping block is disposed in the mounting groove and is located near the movable tube. The pad is disposed in the mounting groove and is located away from the movable tube. The outer wall of the guide joint has a screw hole communicating with the mounting groove. The screw is screwed into the screw hole and its inner end abuts against the pad.
[0006] A preferred technical solution is that the top of the active tube is provided with a folding handle.
[0007] A preferred technical solution is that the outer wall of the fixing tube is provided with a through hole, which is correspondingly provided with the screw hole and allows the screw to pass through.
[0008] The preferred technical solution is as follows: the side of the clamping block near the movable tube is configured as an arc-shaped structure that fits against the wall of the movable tube; the movable tube adopts a circular tube structure.
[0009] The preferred technical solution is that the fixing tube adopts a flat tube structure.
[0010] A preferred technical solution is that the pad has a positioning groove on the side near the screw, and the end of the screw abuts in the positioning groove.
[0011] A wheelchair comprising the push handle structure described in any of the preceding claims.
[0012] Due to the application of the above technical solution, the beneficial effects of this utility model are as follows:
[0013] This utility model proposes a push handle structure and wheelchair. By setting an installation groove in the guide joint, a clamping block is placed in the installation groove and positioned close to the movable tube, and a pad is placed in the installation groove and positioned away from the movable tube. A screw hole communicating with the installation groove is set on the outer wall of the guide joint. A screw is screwed into the screw hole and its inner end abuts against the pad. By turning the screw, the clamping block can be controlled to press or move away from the movable tube, thereby achieving stepless adjustment of the height of the movable tube to suit people of different heights. In addition, the foldable push handle structure makes it easier to store the wheelchair and is suitable for widespread use. Attached Figure Description
