Technical Field

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

[0002] A wheelchair is a chair with wheels that can help replace walking. It is divided into electric and manual wheelchairs. The structure of a wheelchair is mainly composed of a foldable frame, front and rear wheels, left and right knee pads and foot pedals, left and right detachable armrests, etc. It is an important means of transportation for the injured, sick, and disabled to recover at home, for turnover transportation, for medical treatment, and for going out. The wheelchair not only meets the needs of the physically disabled and people with limited mobility, but more importantly, it is convenient for family members to move and take care of the patients, so that the patients can use the wheelchair to exercise and participate in social activities.

[0003] Most existing wheelchairs can only provide mobility services for people with limited mobility, but are not able to rock back and forth. The disadvantage of a rocking chair is that it is difficult for a person to move while sitting in it, so it is difficult to switch between wheelchairs and rocking chairs, which reduces the recreational use of the wheelchair. To this end, we provide a rocking wheelchair to solve the above problems. Utility Model Content

[0004] In order to solve the problems raised in the above background technology, the utility model provides a rocking wheelchair.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rocking wheelchair, comprising a seat body, and also comprising armrest brackets arranged on both sides of the seat body, a fixed shaft and a plurality of support columns are fixedly connected between the two armrest brackets, a mounting shaft is fixedly connected to the middle part of the fixed shaft, the seat body is detachably connected to the mounting shaft, and the seat body is supported on the support columns, the armrests of the two armrest brackets are both arranged in an arc shape, front wheels are installed on the two foot pedal sides of the seat body, both ends of the fixed shaft are rotatably connected to rear wheels, and the rotating shaft of the rear wheel is rotatably connected to the middle part of the armrest bracket.

[0006] In the above technical solution, preferably, both ends of the fixed shaft are provided with brake mechanisms for stopping the rear wheels.

[0007] In the above technical solution, preferably, the brake mechanism includes a brake disc fixedly connected to the rear wheel rotating shaft, and the brake disc is sleeved on the surface of the fixed shaft, the surface of the brake disc is sleeved with a brake sleeve, the side of the brake sleeve is hinged to the surface of the fixed shaft, and the other end of the brake sleeve is fixedly connected to a steel wire rope, one end of the steel wire rope passes through the bottom of the seat body seat plate and is connected to the front end of the seat body foot pedal.

[0008] In the above technical solution, preferably, a handle is installed at one end of the two armrest brackets.

[0009] In the above technical solution, preferably, a plurality of reinforcing columns are fixedly connected to each of the handrail brackets.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] 1. The utility model can convert the wheelchair into a rocking chair by coordinating the armrest brackets, the fixed shaft, the mounting shaft, the seat body, the front wheels, the rear wheels and the support columns. When the wheelchair needs to be converted into a rocking chair, the seat body is first removed from the mounting shaft, and then the two armrest brackets are laid down so that the armrests of the two armrest brackets contact the bottom surface, and the two rear wheels are propped up to prevent further movement. Then, the seat body is placed on the support column between the two armrest brackets, so that the wheelchair can be converted into a rocking chair, and a person can sit on the seat body and rock it, thereby improving the leisure function of the device.

[0012] 2. The utility model is provided with a brake mechanism. When a person uses the device to move normally, if braking is required, the person only needs to step down on the foot pedal on the seat body, thereby pulling the wire rope and driving the brake sleeve to rotate around the hinge shaft on the fixed shaft, so that the brake sleeve contacts the brake disc and brakes it, thereby braking the rear wheel, and the operation is more convenient.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figures 1 to 4 As shown, the utility model provides a rocking wheelchair, including a seat body 1, and also includes armrest brackets 7 arranged on both sides of the seat body 1, a fixed shaft 2 and a plurality of support columns 10 are fixedly connected between the two armrest brackets 7, a mounting shaft 4 is fixedly connected to the middle of the fixed shaft 2, the seat body 1 is detachably connected to the mounting shaft 4, the mounting method of the mounting shaft 4 is an existing mature technology, which is not described in detail here, and the seat body 1 is supported on the support column 10, providing support stability for the seat body 1, and the armrests of the two armrest brackets 7 are both set to arc shape, when the two armrest brackets 7 When the armrests of the seat body 1 are laid down on the bottom surface, the armrests of the armrest brackets 7 are higher than the rear wheels 6. Therefore, the rear wheels 6 will not touch the bottom surface at this time and will naturally not move. Then the seat body 1 is placed on the support column 10 between the two armrest brackets 7, so that the wheelchair can be converted into a rocking chair. People can sit on the seat body 1 and rock it, which improves the leisure function of the device. Front wheels 5 are installed on the sides of the two footrests of the seat body 1, and the two ends of the fixed shaft 2 are rotatably connected to the rear wheels 6, and the rotating shaft of the rear wheel 6 is rotatably connected to the middle of the armrest bracket 7.

[0020] like Figure 1 , Figure 2 As shown, both ends of the fixed shaft 2 are provided with brake mechanisms for stopping the rear wheels 6, so that personnel can brake in normal use.

[0021] like Figure 1 , Figure 2 As shown, the brake mechanism includes a brake disc 93 fixedly connected to the rotating shaft of the rear wheel 6, and the brake disc 93 is sleeved on the surface of the fixed shaft 2. The surface of the brake disc 93 is sleeved with a brake sleeve 92. The brake sleeve 92 is U-shaped, so that the inner wall of the brake sleeve 92 is sleeved on the surface of the brake disc 93, and the inner wall of the brake sleeve 92 does not contact the brake disc 93. The side of the brake sleeve 92 is hinged to the surface of the fixed shaft 2, so that the brake sleeve 92 can rotate around the hinge on the fixed shaft 2, so that the inner wall of the brake sleeve 92 can contact the brake disc 93 to brake it. To stop the vehicle, the other end of the brake sleeve 92 is fixedly connected with a steel wire rope 91, one end of the steel wire rope 91 passes through the bottom of the seat board of the seat body 1 and is connected to the front end of the foot pedal of the seat body 1. Through the setting of the above structure, when the personnel use the device normally to move, if they need to stop the vehicle, they only need to step down on the foot pedal on the seat body 1, thereby pulling the steel wire rope 91 and driving the brake sleeve 92 to rotate around the hinge axis on the fixed axis 2, so that the brake sleeve 92 contacts the brake disc 93 and brakes it, thereby braking the rear wheel 6, and the operation is more convenient.

[0022] like Figures 1 to 4 As shown, a handle 8 is installed at one end of each of the two armrest brackets 7. The handle 8 is provided to facilitate family members or care workers to push the device by holding the handle 8.
