Technical Field

[0001] The invention relates to the technical field of crutch, in particular to a portable nursing crutch. Background Art

[0002] Nursing crutch is a medical crutch, which is an important medical rehabilitation aid. It is mainly used to assist patients with lower limb fractures and mobility impairment to walk. In the field of medical assistive devices, crutches, as an important tool to assist walking, play an irreplaceable role for patients with mobility impairment. Medical crutches include hand crutches, elbow crutches, axillary crutches and four-legged crutches. Among them, axillary crutches are suitable for people with severe lower limb disabilities.

[0003] The existing nursing crutches are mainly composed of an armpit support, a handle, a support rod (or bracket), a non-slip foot pad and other parts. When in use, part of the patient's weight is transferred to the upper limbs through the crutches and fixing belts (such as the armpit support and the handle), thereby reducing the weight on the lower limbs and assisting the patient in walking.

[0004] Currently, there are also axillary crutches on the market that can adjust the height and handle position to fit patients of different heights, and can be folded and carried, but at this time, the axillary crutches have the following defects:

[0005] An axillary crutches includes two crutches. Currently, the two crutches cannot be folded and connected together, but are still in a separate state. Therefore, it is easy for a single crutch to be missed or lost during carrying. Moreover, the functions of the axillary crutches on the market are relatively single, mainly limited to assisting walking. In actual use, it is relatively difficult for patients to walk with the axillary crutches. Therefore, there is a need for the crutches to have the function of temporary rest.

[0006] Therefore, it is necessary to design a multifunctional portable nursing crutch to solve the above problems. Summary of the invention

[0007] The present invention provides a portable nursing crutch, which solves the above-mentioned technical problems.

The limiting spring 52 fixed on the top of the fixed plate 53 is inserted into the leg tube 6. The limiting sleeve 51 movably sleeved on the leg tube 6 is fixedly connected to the limiting spring 52. The limiting sleeve 51 is funnel-shaped, and the limiting sleeve 51 can cover the lower part of the two folding structures for limiting.

[0035] Specifically, when the leg tube 6 needs to be folded, the limiting sleeve 51 is grasped and applied downward force to squeeze and contract the limiting spring 52 to store force, and the limiting sleeve 51 is separated from the two folding structures. The user grasps the leg tube 6 and can flip it upward to combine with the crutch body 1, release the limiting sleeve 51, and the limiting spring 52 rebounds to drive the limiting sleeve 51 back to its original position.

[0036] In this embodiment, the grip structure 4 includes a handle 42, the outside of the handle 42 is covered with a silicone sleeve 41, a pin 44 is fixed to one side of the handle 42, and an adjusting bolt 43 is threadedly connected to the other side of the handle 42. A limiting groove 45 is provided in the middle of the silicone sleeve 41 and the handle 42, and a flip cover 46 is flexibly connected to the edge of the limiting groove 45. A buckle groove 46 is provided on one edge of the flip cover 46. The handle 42 is arranged inside the crutch body 1, and the connecting pin 44 of the handle 42 is inserted into one of the adjustment holes 11, and the adjusting bolt 43 passes through another parallel adjustment hole 11 and is threadedly connected to the handle 42 for limiting, and the foot pad 62 cooperates with the limiting groove 45 for plugging and limiting.

[0038] Embodiment 2, on the basis of embodiment 1, the connecting belt structure 3 includes a connecting tube 31 fixed at the bottom of the armpit support 2, a connecting groove 311 is opened at the bottom of the connecting tube 31, a connecting shaft 32 is rotatably connected inside the connecting tube 31, and vortex springs 33 are arranged on the edges on both sides of the inside of the connecting tube 31 and are inserted into the connecting shaft 32, one end of the vortex spring 33 is fixed to the connecting shaft 32, and the other end of the outside is fixed to the inner wall of the connecting tube 31, a supporting cloth 34 is wound around the outside of the connecting shaft 32, one end of the supporting cloth 34 passes through the connecting groove 311 and is fixed with a blocking plate 35, and two elastic telescopic structures 36 are symmetrically installed on both side ends of the blocking plate 35.

[0039] Specifically, after the two medical crutches are folded, the blocking plate 35 of the first medical crutch is grabbed and pulled out, driving the supporting cloth 34 to rotate and unwind the connecting shaft 32, and the spiral spring 33 contracts to accumulate force, pressing and contracting the two elastic telescopic structures 36, so that the blocking plate 35 can be inserted into the through-slot 21 of the second medical crutch, and then the finger is inserted into the through-slot 21 to push the blocking plate 35 through the through-slot 21, and the two elastic telescopic structures 36 rebound and extend out, limiting the blocking plate 35 passing through the through-slot 21, and at the same time, the spiral spring 33 rebounds and drives the connecting shaft 32 to rewind the supporting cloth 34, and the two folded medical crutches are connected together. This folding method is not only convenient to carry, but also less likely to cause a single medical crutch to be lost.

[0040] Among them, the elastic telescopic structure 36 includes a telescopic groove 361 opened at the side end of the blocking plate 35, a telescopic spring 362 is fixed inside the telescopic groove 361, and a telescopic block 363 is inserted into the opening of the telescopic groove 361 and fixedly connected with the telescopic spring 362. The two telescopic blocks 363 are forced to shrink into the telescopic groove 361 to squeeze the telescopic spring 362, so that the blocking plate 35 can be inserted into the through groove 21, and then a finger is inserted into the through groove 21 to push the blocking plate 35 through the through groove 21. The telescopic spring 362 rebounds and drives the telescopic block 363 to extend, thereby limiting the blocking plate 35 passing through the through groove 21.

[0041] Embodiment 3, on the basis of embodiment 1, the folding structure includes a folding rod 13 and a rotating groove 12 opened at the bottom tube end of the crutch body 1, a rotating block 131 is fixed on the top of the folding rod 13, the rotating block 131 is inserted into the rotating groove 12 through the rotating shaft through the thread, the length of the blocking plate 35 is less than the length of the through groove 21, and the sum of the blocking plate 35 and the two elastic telescopic structures 36 is greater than the length of the through groove 21.

[0042] Specifically, since the leg tube 6 is folded, the elastic limiting structure 5 is separated from the folding structure, so the folding rod 13 can be turned ninety degrees in the rotating groove 12 through the rotating block 131, and can be used as a supporting foot when it contacts the ground, so that it remains stable and is not easy to tip over.

[0043] Working principle:

[0044] When using two medical crutches, according to the patient's height, the foot pad 62 of the first medical crutch is grasped and rotated, driving the threaded rod 61 to rotate and extend out of the internal thread groove of the foot tube 6, thereby adjusting the height of the medical crutch so that the armpit support 2 on the crutch body 1 can contact the patient's armpit, and then according to the patient's arm length, the hand grip structure 4 is installed on a suitable set of adjustment holes 11, the adjustment bolt 43 is rotated to separate from the grip 42, the grip 42 is grasped to insert the pin 44 into one of the adjustment holes 11, and then the adjustment bolt 43 is passed through the adjustment hole 11 parallel to it, and the adjustment bolt 43 is inserted into the adjustment hole 11 parallel to it. The handle 42 is threadedly connected to achieve limited installation. The second medical crutch is operated in the same way. The patient grasps the two medical crutch handles 42 and brings the crutch body 1 under the armpit. The foot pad 62 on the leg tube 6 contacts the ground. The two medical crutches are supported back and forth with the arms to assist the patient in moving. During the use of the medical crutch, the armpit support 2 is made of TPR material and is relatively comfortable in contact with the armpit. A through groove 21 is opened in the middle of the armpit support 2. During the force application process of the armpit support 2, the through groove 21 is squeezed and deformed, which has a certain buffering effect and further improves comfort.

[0045] When carrying two medical crutches folded together, Figure 7As shown, the hand grip structure 4 of the first medical crutch is adjusted to the middle position of the multiple groups of adjustment holes 11 for installation, and then the buckle groove 461 is grasped to open the flip cover 46 to reveal the limit groove 45. Next, the limit sleeve 51 is grasped and applied downward to squeeze and contract the limit spring 52 to store force, and the limit sleeve 51 is separated from the two folding structures. The user grasps the foot tube 6 to flip it upward to combine with the crutch body 1, and the foot pad 62 is embedded in the limit groove 45 to clamp the limit. The second medical crutch is operated in the same way. Finally, the blocking plate 35 of the first medical crutch is grasped and pulled out, driving the supporting cloth 34 to rotate and unwind the connecting shaft 32, and the spiral spring 33 contracts to store force. The force is applied to press and contract the two elastic telescopic structures 36. The two telescopic blocks 363 are contracted into the telescopic grooves 361 by the force to squeeze the telescopic springs 362, so that the blocking plate 35 can be inserted into the through groove 21 of the second medical crutch. Then, the finger is inserted into the through groove 21 to push the blocking plate 35 through the through groove 21. The telescopic spring 362 rebounds and drives the telescopic block 363 to extend, limiting the blocking plate 35 passing through the through groove 21. At the same time, the spiral spring 33 rebounds and drives the connecting shaft 32 to reel up the supporting cloth 34. The two folding medical crutches are connected together. This folding method is not only convenient to carry, but also not easy to cause the loss of a single medical crutch.

[0046] When two medical crutches are used as a temporary resting stool, Figure 8As shown, the hand grip structure 4 of the first medical crutch is adjusted to the lowest position of the multiple groups of adjustment holes 11 for installation, and then the buckle groove 461 is grasped to open the flip cover 46 to expose the limit groove 45, and then the limit sleeve 51 is grasped and grasped downward to squeeze and contract the limit spring 52 to store force, and the limit sleeve 51 is separated from the two folding structures, so that the leg tube 6 can be freely flipped, and the elastic limit structure 5 of the second medical crutch is operated in the same way, so that the corresponding leg tube 6 can be flipped upward, and the foot pad 62 is grasped and rotated, driving the threaded rod 61 to rotate and extend the foot. The inner thread groove of the tube 6, during the upward flipping of the leg tube 6, the foot pad 62 can be embedded in the limiting groove 45 of the first medical crutch hand grip structure 4 for limiting position, and then the leg tube 6 of the first medical crutch is flipped upward to expose part of it to the threaded rod 61, which can be inserted between the two tubes at the bottom of the crutch body 1 of the second medical crutch, and the foot pad 62 is rotated to drive the threaded rod 61 to contract, so that the foot pad 62 contacts the bottom of the second medical crutch for limiting position, and then the blocking plate 35 is grabbed and pulled out, driving the supporting cloth 34 to make the connecting shaft 32 rotate and unwind, The spiral spring 33 is driven to contract and store force, and the supporting cloth 34 surrounds the armpit support 2 of the first medical crutch and the second crutch, and the two elastic telescopic structures 36 are pressed and contracted to be inserted from the outside of the through slot 21 of the second medical crutch, and then the finger is inserted into the through slot 21 to push the blocking plate 35 through the through slot 21, and the telescopic spring 362 rebounds and drives the telescopic block 363 to extend, limiting the blocking plate 35 passing through the through slot 21. At this time, the connecting shaft 32 is completely unwound and connected to the supporting cloth 34. Due to the flipping of the leg tube 6, the four folding parts of the two medical crutches are now The structure is not limited, so the folding rod 13 can be flipped ninety degrees in the rotating groove 12 through the rotating block 131, and can be used as a supporting foot when it contacts the ground to keep it stable and not easy to tip over. After the two medical crutches are folded and combined into a stool as a whole, the user can sit on the stretched supporting cloth 34, and the supporting cloth 34 drives the two medical crutches to be stressed. The two medical crutches are kept fully stretched out by the inclined leg tubes 6, and the two medical crutches are connected and limited by the horizontal leg tubes 6, so that they can still maintain stability when subjected to force and are not easy to collapse.
