Description

Technical Field

[0001] The utility model belongs to the technical field of wheelchairs, and in particular relates to a standing wheelchair. Background Art

[0002] A wheelchair is a chair with wheels that can help replace walking. It is an important means of transportation for the injured, sick, and disabled to recover at home, be transported around, see a doctor, and go out for activities. Wheelchairs not only meet the needs of people with physical disabilities and mobility impairments, but more importantly, they facilitate family members to move and take care of patients, and enable patients to exercise and participate in social activities with the help of wheelchairs.

[0003] Since the existing wheelchairs have a fixed body and frame, when the user needs to stand, the user still needs help from others to leave the wheelchair. For some patients who only have difficulty in walking but still have the ability to stand, the complex structure of the wheelchair becomes an obstacle to standing up from the wheelchair. Secondly, the height of the handle on the wheelchair is fixed, and the patient can maintain body balance through the handle. However, due to the different heights of patients, the handle of the specified height is only suitable for some people, which reduces the practicality of the device. Therefore, we provide a standing wheelchair. Utility Model Content

[0004] The purpose of the utility model is to provide a standing wheelchair to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a standing wheelchair, comprising a base plate and a backrest, a box body is fixedly connected to the left side of the top of the base plate, a No. 1 movable shaft is fixedly connected to the right side of the top of the front surface and the back of the box body, a seat plate is hinged on the inner side of the No. 1 movable shaft, a No. 2 movable shaft is fixedly connected to the bottom of the front surface and the back of the backrest, the other end of the seat plate is hinged to the inner side of the No. 2 movable shaft, a No. 4 movable shaft is fixedly connected to the bottom of the seat plate, a motor is fixedly installed on the left side of the inner cavity of the box body, a threaded rod is fixedly connected to the output end of the motor, a threaded sleeve is threadedly connected to the surface of the threaded rod, a No. 3 movable shaft is fixedly connected to the top of the threaded sleeve, the No. 3 movable shaft and the No. 4 movable shaft are hinged by a connecting rod, a shell is fixedly connected to the right side of the top of the base plate, an electric telescopic rod is fixedly connected to the bottom of the inner cavity of the shell body, a movable plate is fixedly connected to the top of the electric telescopic rod, a rectangular rod is fixedly connected to the top of the movable plate, and handles are fixedly connected to both sides of the rectangular rod and located outside the shell.

[0006] When the patient needs to stand, the electric telescopic rod is started, and the movable plate is driven to move upward by the electric telescopic rod, and the rectangular rod is driven to move upward by the movable plate, and the handle is driven to move upward by the rectangular rod, so as to achieve the purpose of adjusting the height of the handle, so that it can be suitable for patients of different heights, thereby improving the applicability of the device. Secondly, the motor is started, and the threaded rod is driven to rotate by the motor. Because the external thread on the surface of the threaded rod is matched with the internal thread on the inner wall of the threaded sleeve, when the threaded rod rotates forward or reversely, the threaded sleeve can be driven to move left or right. When the threaded rod rotates forward, the threaded sleeve is driven to move right by the threaded rod, and the No. 3 movable shaft is driven to move right by the threaded sleeve. When the No. 3 movable shaft is moving, thrust is generated, and it is used in conjunction with the connecting rod and the No. 4 movable shaft, so that one end of the seat plate rotates on the inner side of the No. 1 movable shaft until the seat plate is in a vertical state and the movement stops, so that the wheelchair can realize the function of standing. Similarly, when the seat plate needs to be reset, the reverse operation is sufficient. The device does not require the help of external personnel, is simple to operate, and is easy to use.

[0007] As a preferred embodiment of a standing wheelchair, a slideway is fixedly connected to the right side of the inner cavity of the box body, a slider is fixedly connected to the bottom of the threaded sleeve, and the bottom of the slider is slidably connected to the inner wall of the slideway.

[0008] By adopting the above solution, the slide block is limited by setting the slideway, and the threaded sleeve is assisted to move, thereby preventing the threaded sleeve from rotating.
