Detailed Description

Referring to fig. 1-5, this embodiment discloses a wheelchair, including wheelchair body 1, one side symmetry of wheelchair body 1 is provided with leg rest 4, the bottom of leg rest 4 is provided with running-board 5, be provided with adjusting device 2 between wheelchair body 1 and the leg rest 4, set up telescoping device 3 between leg rest 4 and the running-board 5, adjusting device 2 includes two connecting blocks 21, one side of connecting block 21 and one side fixed connection of wheelchair body 1, fixedly connected with round bar 22 between two connecting blocks 21, the surface symmetry rotation of round bar 22 is connected with ring piece 23, the surface of ring piece 23 and the top fixed connection of leg rest 4, arc hole 24 has been seted up to one side of connecting block 21, one side fixedly connected with threaded rod 25 of leg rest 4, the inner wall size of arc hole 24 and the surface size looks adaptation of threaded rod 25, the surface rotation of threaded rod 25 is connected with turning block 26. After a patient sits on the wheelchair body 1, the two leg frames 4 can be manually rotated respectively according to the injured bending condition of the legs of the patient, the ring block 23 is driven to rotate to a corresponding angle on the round rod 22, the leg frame 4 can be rotated to drive the threaded rod 25 to rotate to a corresponding angle in the arc-shaped hole 24 on the connecting block 21, the rotating block 26 is manually held to rotate the rotating block, the leg frames 4 which are rotated to a corresponding height can be fixedly limited on the connecting block 21 after the rotating block 26 is rotated to a corresponding position on the threaded rod 25, and therefore the leg frames 4 support the legs of the patient at different heights, and leg muscles of the patient can not be in the same state for a long time, so that the recovery of the patient is facilitated.

Referring to fig. 2 and 3, this embodiment discloses that a plurality of anti-slip strips 27 are fixedly connected to two sides of the rotating block 26, and the anti-slip strips 27 are arranged equidistantly. When the two sides of the rotating block 26 are manually held, the anti-slip strips 27 can increase friction force on the two sides, so that the hands are more firmly held and are not easy to slip. The bottom of the rotating block 26 is fixedly connected with a first anti-skid block 28, and the size of the inner wall of the arc-shaped hole 24 is matched with the size of the outer surface of the first anti-skid block 28. The first anti-slip block 28 can increase the friction force at the bottom of the rotating block 26, so that the bottom of the rotating block 26 can be clung to one side of the connecting block 21 after the rotating block 26 rotates to the corresponding position on the threaded rod 25, and the first anti-slip block 28 is clamped into the arc-shaped hole 24, so that the rotating block 26 is limited.

Referring to fig. 2 and 3, this embodiment discloses that a stopper 29 is fixedly connected to the top of the threaded rod 25, and the outer surface of the stopper 29 is larger than the inner wall of the rotating block 26. After the rotation block 26 rotates to the corresponding position on the threaded rod 25, the limiting block 29 can limit and fix the rotation block, so that the rotation block cannot continue to rotate in a threaded manner and rotate out of the threaded rod 25.

Referring to fig. 4 and 5, this embodiment discloses that the telescoping device 3 includes rectangular bar 31 and fixture block 35, a plurality of first round hole 32 has been seted up to one side of rectangular bar 31, rectangular groove 33 has been seted up to the bottom of rectangular bar 31 and the top fixed connection of running-board 5, rectangular groove 33 has been seted up to the bottom of leg rest 4, the inner wall of rectangular groove 33 and the surface interactive connection of rectangular bar 31, one side of leg rest 4 is seted up and is linked together with second round hole 34, the inner wall of second round hole 34 and the inner wall of rectangular groove 33 are linked together, the inner wall size and the shape of first round hole 32 and second round hole 34 all with the surface size and the shape looks adaptation of fixture block 35. According to the height and leg length of a patient, after the patient sits on the wheelchair body 1, the foot pedal 5 can be manually pulled to drive the rectangular rod 31 to slide outwards in the rectangular groove 33 on the leg frame 4, so that the rectangular rod 31 is manually clamped into the first round hole 32 and the second round hole 34 after the rectangular rod slides to the corresponding position, the rectangular rod 31 can be fixedly limited on the leg frame 4 after being stretched, and the leg length of the patient can be adjusted to the corresponding length, so that the leg of the patient is in the most comfortable posture.

Referring to fig. 4 and 5, this embodiment discloses that the outer surface of the clamping block 35 is fixedly connected with a second anti-slip block 36, and the sizes and shapes of the inner walls of the first round hole 32 and the second round hole 34 are matched with those of the outer surface of the second anti-slip block 36. The second anti-slip block 36 can increase the friction force on the surface of the clamping block 35, so that the clamping block 35 is not easy to slip after being clamped in the first round hole 32 and the second round hole 34. The top of the clamping block 35 is fixedly connected with a connecting rope 37, and one end of the connecting rope 37 is fixedly connected with one side of the leg frame 4. The connecting rope 37 can fix and limit the clamping block 35 on one side of the leg frame 4, so that the clamping block 35 is not easy to lose.

The working principle is as follows: after a patient sits on the wheelchair body 1, the two leg frames 4 can be manually rotated respectively according to the injured bending condition of the legs of the patient, the ring block 23 is driven to rotate to a corresponding angle on the round rod 22, the leg frame 4 can be rotated to drive the threaded rod 25 to rotate to a corresponding angle in the arc-shaped hole 24 on the connecting block 21, the rotating block 26 and the anti-slip strip 27 are manually held to rotate the same, so that the bottom and the first anti-slip block 28 of the patient are respectively abutted against the connecting block 21 and the arc-shaped hole 24 after the rotating block 25 rotates to a corresponding position, and the leg frames 4 rotated to a corresponding height can be fixedly limited on the connecting block 21, so that the leg frames 4 support the legs of the patient at different heights, and the leg muscles of the patient can not be in the same state for a long time, thereby being beneficial to the recovery of the patient.

According to the height and leg length of a patient, after the patient sits on the wheelchair body 1, the foot pedal 5 can be manually pulled to drive the rectangular rod 31 to slide outwards in the rectangular groove 33 on the leg frame 4, so that the rectangular rod slides to the corresponding position, and then the clamping block 35 and the second anti-skid block 36 are manually clamped into the first round hole 32 and the second round hole 34, so that the rectangular rod 31 can be fixedly limited on the leg frame 4 after being stretched, and the leg length of the patient can be adjusted to the corresponding length, so that the leg of the patient is in the most comfortable posture.
