DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1-6 As shown, a portable orthopedic nursing crutch includes a bracket 1, a leg 2, an armpit support 3 and a handle 4. The bottom end of the bracket 1 is connected to a support column 5, which supports the components to be carried. A slide groove 6 is provided at the bottom end of the support column 5, and a first slide 7 is provided on the inner side of the support column 5. The inner wall of the slide groove 6 is in sliding contact with one end of the leg 2. A second slide 8 is provided on the inner side of the leg 2. The support column 5 has space for accommodating the leg 2 through the slide groove 6. The leg 2 provides space for a locking bolt 10 through the second slide 8. The second slide 8 is a special shape, similar to an L shape in appearance. The second slide 8 is used to reserve space for the support leg 2 when it is flipped, and the length of the portable orthopedic nursing crutch is shortened by flipping the support leg 2. A threaded block 9 is connected to one side of the support column 5, and the inner wall of the threaded block 9 is threadedly connected to a locking bolt 10. The outer surface of the locking bolt 10 contacts the inner wall of the first slide 7 and the second slide 8. By rotating the locking bolt 10, the support column 5 is contracted to compress the space of the slide groove 6. When the slide groove 6 is compressed, the support leg 2 is squeezed, thereby improving the stability of the support leg 2. The threaded block 9 is used to move the locking bolt 10 during rotation, thereby squeezing the support leg 2.

[0025] The inner wall of the support leg 2 is in sliding contact with an extension leg 11, and the bottom end of the extension leg 11 is connected to a non-slip rubber pad 13. The support length of the portable orthopedic nursing crutch can be adjusted by extending the leg 11 to adapt to patients of different heights.

[0026] A positioning mechanism 12 is provided on the outside of the support leg 2. After the length of the extension leg 11 is adjusted, the positioning mechanism 12 is used to limit the movement of the extension leg 11. The positioning mechanism 12 includes a first screw rod 1201. The outer surface of the first screw rod 1201 is threadedly connected to the inner side of the support leg 2. One end of the first screw rod 1201 located inside the support leg 2 is rotatably connected to a clamping block 1202. By rotating the first screw rod 1201, power is provided for the movement of the clamping block 1202, pushing the clamping block 1202 to move its position. A clamping plate 1203 is connected to the outer surface of the extension leg 11. The outer surface of the clamping plate 1203 is in sliding contact with the inner wall of the support leg 2. One side of the clamping plate 1203 is in contact with one side of the clamping block 1202. After the clamping block 1202 moves its position, it is in tight contact with the clamping plate 1203, thereby limiting the movement of the extension leg 11 and making the extension leg 11 stable.

[0027] A positioning groove 14 is provided on the inner side of the support column 5, and a positioning block 15 is connected to the outer surface of the support leg 2. The outer surface of the positioning block 15 contacts the inner wall of the positioning groove 14, and the positioning block 15 is wrapped by the positioning groove 14 to improve the stability of the support leg 2.

[0028] The top of the bracket 1 is connected to the lower surface of the armpit support 3. A ventilation groove 16 is provided on the inner side of the armpit support 3 to improve the patient's comfort when using the armpit support 3 and to facilitate heat dissipation to the patient's armpit through the ventilation groove 16.

[0029] Two adjustment slots 17 are provided on the inner side of the bracket 1, and the two adjustment slots 17 are symmetrical. Two card slots 18 are provided on the inner side of the bracket 1, and the two card slots 18 are symmetrical with the two adjustment slots 17. The inner walls of the two card slots 18 are in contact with an adjustment block 19, and the card slot 18 forms a block for the adjustment block 19 to improve the stability of the adjustment block 19. The second screw rod 20 has space to move its position through the adjustment slot 17. The inner wall of one of the adjustment blocks 19 is in contact with a second screw rod 20, and the other end of the second screw rod 20 is threadedly connected to the inner side of the other adjustment block 19. The outer surface of the second screw rod 20 is in contact with the inner wall of the handle 4, and the handle 4 is convenient for the patient to take off the crutch. The second screw rod 20 provides support for the handle 4. When adjusting the height of the handle 4, the two adjustment blocks 19 are disengaged from the card slot 18 by rotating the second screw rod 20, and then the handle 4 is dragged to the appropriate position, and the second screw rod 20 is rotated to move the two adjustment blocks 19 into the inside of the card slot 18.

[0030] It should be noted that in actual use of the device, the locking bolt 10 is first rotated to create a gap between the slide groove 6 and the leg 2, and then the leg 2 is pulled downward to disengage the positioning block 15 from the positioning groove 14. The leg 2 is flipped over to fold the leg 2 and the bracket 1 together, and the locking bolt 10 is rotated in the opposite direction to shrink the slide groove 6, thereby forming a clamping effect on the leg 2, so that the folded portable orthopedic care crutch has stability and will not unfold after folding.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
