Description

Technical Field

[0001] This utility model relates to the field of axillary cane technology, specifically an axillary cane with anti-slip effect. Background Technology

[0002] Axillary canes are an important assistive walking tool. Their main function is to provide users with additional support and stability. By distributing body weight, axillary canes can effectively reduce pressure on the lower limbs, making them especially suitable for people with lower limb injuries, those recovering from surgery, or those suffering from conditions such as arthritis. They can play an important role in the rehabilitation process, promoting the enhancement of muscle strength and coordination. When using axillary canes, correct posture and method are crucial. At the same time, following the guidance of professional medical personnel or rehabilitation therapists and learning how to use axillary canes correctly, including gait and rhythm when walking, can maximize their assistive effects.

[0003] According to the search results, the Chinese patent document, publication number: CN 220801411 U.S. discloses a cane and cane assembly. This application relates to a cane and cane assembly. The cane assembly includes a base, a foot pad at the bottom of the base, a connecting cylinder, and a fastening cylinder. The lower end of the connecting cylinder is connected to the top of the base, and the outer side wall has an external thread. The upper end is surrounded by a tightening strip, and the top outer side of the tightening strip is beveled. The lower inner side of the fastening cylinder has an internal thread matching the external thread, and the upper inner side is surrounded by a shoulder. The lower inner diameter of the shoulder gradually decreases from bottom to top. The fastening cylinder is threadedly connected to the connecting cylinder. The cane includes a vertical rod, a handle at the top of the vertical rod, and the aforementioned cane assembly. The lower end of the vertical rod is inserted into the connecting cylinder of the cane assembly. When the cane assembly is in use, the fastening cylinder can squeeze the tightening strip and tighten it inward as it is continuously tightened downward, thereby tightly gripping the lower part of the vertical rod and securing the lower end of the vertical rod in the connecting cylinder. Moreover, the fastening cylinder is difficult to detach, ensuring the stability of the detachable connection part.

[0004] In practical use, the aforementioned device improves the grip and stability of the cane on different surfaces by incorporating a suction cup at the bottom. However, in winter, when the ground is often covered with ice and snow, the suction cup is difficult to adhere effectively to smooth ice surfaces, resulting in a lack of stable support for the user. When walking with the cane, the user may feel unstable due to the suction cup losing grip, potentially increasing the risk of falling. Therefore, we provide an underarm cane with anti-slip properties. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an armpit cane with anti-slip effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-slip cane, comprising a rubber support foot, a set of corresponding extension rods fixedly connected to both sides of the top surface of the rubber support foot, and a rubber support pad fixedly connected to the outer wall of the top of the extension rod, the extension rods being located at both ends of the rubber support pad on the ground, and one end of the bottom surface of the rubber support pad being fixedly connected to the outer wall of the top of the extension rod, the extension rod having multiple threaded holes inside, and a handle being movably connected to one side of the outer wall of the corresponding side of the extension rod through the threaded holes, the handle being located at the bottom center of the rubber support pad, a follower block being slidably connected to the center inside the rubber support foot, and multiple anti-slip studs being fixedly connected to the bottom outer wall of the follower block, an adjustment knob being rotatably connected to the top of the follower block, and the adjustment knob being located at the top center of the follower block.

[0007] As described above, the inner center of the extension rod is rotatably connected to a bolt through a threaded hole, and the bolt is located at one end inside the handle. The outer center of the bolt is connected through the inner center of the threaded hole, and one end of the outer wall of the bolt is rotatably connected to the inner center of the threaded hole through a thread.

[0008] As described above, one end of the outer wall of the bolt is connected through to one end of the outer wall of the handle, and one end of the outer wall of the bolt is rotatably connected to one end of the inner wall of the handle through a thread. One end of the outer wall of the handle is fixedly connected to one side of the outer wall of the extension rod through a bolt.

[0009] As described above, the rubber support foot has multiple conical holes at its bottom, and the conical holes correspond to the anti-skid spikes. The conical holes are located at the center of the bottom of the anti-skid spikes.

[0010] As described above, the inner center of the rubber support foot is rotatably connected to a threaded screw via an adjustment knob, and the threaded screw is located at the bottom center of the adjustment knob. The outer wall of the top end of the threaded screw penetrates through the top end of the inner wall of the rubber support foot and is fixedly connected to the center of the bottom surface of the adjustment knob.

[0011] As described above, the outer wall of the top end of the threaded screw is connected through the center of the top surface of the follower block, and the two sides of the outer wall of the threaded screw are rotatably connected to the inner center of the follower block through threads.

[0012] As described above, multiple slide rails are fixedly connected to both sides of the inner wall of the rubber support foot, and the multiple slide rails are respectively located on both sides inside the follower block. One side of the outer wall of the slide rail penetrates one side of the outer wall of the follower block, and the inner side of the follower block is slidably connected to one side of the outer wall of the slide rail.

[0013] Compared with existing technologies, this anti-slip cane has the following beneficial effects:

[0014] I. This utility model allows for the rotation of bolts at both ends inside the handle. The bolts rotate along the threaded holes, disengaging from one end of the handle. The handle is then moved to the corresponding height of the threaded hole, and the bolts are rotated through the corresponding threaded holes back into the handle, fixing it at the corresponding height. In this way, medical personnel can easily adjust the handle position according to the user's arm length, ensuring a comfortable and correct posture when using the axillary cane. This effectively improves the flexibility and applicability of the axillary cane, better meeting the needs of different patients.

[0015] II. This utility model, by rotating the adjustment knob, causes the threaded screw to rotate at the center inside the rubber support foot. Under the combined action of the threaded screw and the slide rail, as the threaded screw rotates, the follower block and its multiple anti-slip spikes fixed to the bottom surface are pushed towards the lower end inside the rubber support foot, allowing the anti-slip spikes to pass through the conical hole. In use, the anti-slip spikes will contact the ice or snow surface before the rubber support foot, thus enabling the anti-slip spikes to effectively penetrate the ice or snow surface, providing the user with more stable support and significantly improving the anti-slip performance of the cane in icy and snowy environments. It also increases the safety and stability of the user when walking. Whether on smooth ice or soft snow, the device can ensure that the cane will not easily slip, reducing the risk of falling.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-4 As shown, this utility model provides a technical solution: an armpit cane with anti-slip effect, including a rubber support foot 1. A set of corresponding extension rods 2 are fixedly connected to both sides of the top surface of the rubber support foot 1, and a rubber support pad 201 is fixedly connected to the outer wall of the top of the extension rod 2. The extension rod 2 is located at both ends of the rubber support pad 201 on the ground, and one end of the bottom surface of the rubber support pad 201 is fixedly connected to the outer wall of the top of the extension rod 2. Multiple threaded holes 202 are opened inside the extension rod 2, and a handle 203 is movably connected to one side of the outer wall of the corresponding side of the extension rod 2 through the threaded holes 202. The handle 203 is located at the bottom center of the rubber support pad 201. A follower block 3 is slidably connected to the center inside the rubber support foot 1, and multiple anti-slip snow spikes 301 are fixedly connected to the bottom outer wall of the follower block 3. An adjustment knob 302 is rotatably connected to the top of the follower block 3, and the adjustment knob 302 is located at the top center of the follower block 3.

[0024] The bolts 204 at both ends of the rotatable handle 203 are rotated so that the bolts 204 rotate along the threaded hole 202 and disengage from one end of the handle 203. The handle 203 is then moved to the corresponding height of the threaded hole 202, and the bolts 204 are rotated through the corresponding threaded hole 202 into the handle 203, fixing the handle 203 at the corresponding height. By rotating the adjustment knob 302, the threaded rod 304 rotates to the center inside the rubber support foot 1. Under the combined action of the threaded rod 304 and the slide rail 305, as the threaded rod 304 rotates, the follower block 3 and its... Multiple anti-skid spikes 301 fixed to the bottom are pushed towards the lower end of the rubber support foot 1, allowing the anti-skid spikes 301 to pass through the conical hole 303. During use, the anti-skid spikes 301 will contact the ice or snow surface before the rubber support foot 1, thus enabling the anti-skid spikes 301 to effectively penetrate the ice or snow surface, providing the user with more stable support and significantly improving the anti-slip performance of the cane in icy and snowy environments. It also increases the user's safety and stability when walking. Whether on smooth ice or soft snow, the device can ensure that the cane will not easily slip, reducing the risk of falling.

[0025] like Figure 1-2As shown, a bolt 204 is rotatably connected to the inner center of the extension rod 2 through a threaded hole 202. The bolt 204 is located at one end inside the handle 203. The outer center of the bolt 204 is connected to the inner center of the threaded hole 202. One end of the outer wall of the bolt 204 is rotatably connected to the inner center of the threaded hole 202 through a thread. By rotating the bolt 204 through its outer thread and the inner center of the threaded hole 202, it passes through the threaded hole 202, so that it can fix the handle 203 in the subsequent process.

[0026] One end of the outer wall of the bolt 204 is connected to one end of the outer wall of the handle 203 through the bolt, and one end of the outer wall of the bolt 204 is rotatably connected to one end of the inner wall of the handle 203 through the thread. One end of the outer wall of the handle 203 is fixedly connected to one side of the outer wall of the extension rod 2 through the bolt 204. By passing the bolt 204 through one end of the outer wall of the handle 203, it can effectively cooperate with the threaded hole 202 through the thread on the outer wall, thus fixing the handle 203 to the outer wall of the extension rod 2.

[0027] like Figure 1 , Figure 3 and Figure 4 As shown, the rubber support foot 1 has multiple conical holes 303 at its bottom, and the conical holes 303 correspond to the anti-skid spikes 301. The conical holes 303 are located at the center of the bottom of the anti-skid spikes 301. By opening multiple conical holes 303 at the bottom of the rubber support foot 1 and having the conical holes 303 correspond to the anti-skid spikes 301, the anti-skid spikes 301 can penetrate the conical holes 303 and contact the bottom surface when the height of the anti-skid spikes 301 is adjusted by the follower block 3.

[0028] A threaded screw 304 is rotatably connected to the center of the rubber support foot 1 via an adjustment knob 302. The threaded screw 304 is located at the bottom center of the adjustment knob 302. The outer wall of the top of the threaded screw 304 passes through the top of the inner wall of the rubber support foot 1 and is fixedly connected to the center of the bottom surface of the adjustment knob 302. By fixing the outer wall of the top of the threaded screw 304 to the center of the bottom surface of the adjustment knob 302, the adjustment knob 302 can drive the threaded screw 304 to rotate at the center of the inside of the rubber support foot 1.

[0029] The outer wall of the top end of the threaded screw 304 is connected through the center of the top surface of the follower block 3, and the two sides of the outer wall of the threaded screw 304 are rotatably connected to the inner center of the follower block 3 through the threads. By passing through the inner center of the follower block 3, the threaded screw 304 can be rotatably connected to the inner center of the follower block 3 through the threads on the outer wall.

[0030] Multiple slide rails 305 are fixedly connected to both sides of the inner wall of the rubber support foot 1. The multiple slide rails 305 are located on both sides of the inside of the follower block 3. One side of the outer wall of the slide rail 305 passes through one side of the outer wall of the follower block 3, and the inner side of the follower block 3 is slidably connected to one side of the outer wall of the slide rail 305. By passing through one side of the inner wall of the follower block 3, the slide rail 305 limits the movement trajectory of the follower block 3.

[0031] Working principle: The bolt 204 is rotated through the threaded hole 202 on its outer wall and rotated to fix the handle 203 in subsequent processes. By passing the bolt 204 through one end of the outer wall of the handle 203, the outer wall thread and the threaded hole 202 are effectively engaged, fixing the handle 203 to the outer wall of the extension rod 2. Multiple tapered holes 303 are opened at the bottom of the rubber support foot 1, and the tapered holes 303 correspond to the anti-slip spikes 301, so that the anti-slip can be adjusted by the follower block 3. When the snow spikes 301 are at the desired height, the anti-skid spikes 301 can penetrate the conical hole 303 and contact the bottom surface. The outer wall of the top of the threaded rod 304 is fixedly connected to the center of the bottom surface of the adjusting knob 302, so that the adjusting knob 302 can drive the threaded rod 304 to rotate at the center inside the rubber support foot 1. The threaded rod 304 passes through the center inside the follower block 3, so that the threaded rod 304 can be rotatably connected to the center inside the follower block 3 through the thread on the outer wall. By passing through one side of the follower block 3, the slide rail 305 limits the movement trajectory of the follower block 3.
