Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically to a cushioning and shock-absorbing axillary crutch. Background Technology

[0002] Axillary canes are a common medical device used to assist patients with lower limb injuries in walking. Existing axillary canes are generally a rigid stick formed from a single piece. When using such a cane to support the ground, the bottom of the cane touches the ground, and the cane will be subjected to a reaction force from the ground. This reaction force will be transmitted to the patient's armpit through the cane. After using the cane for a period of time, the armpit is prone to numbness under the action of the reaction force. Under the condition of a large reaction force, the armpit is even prone to injury, which has certain limitations. Utility Model Content

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figures 1 to 7As shown, the cushioning and shock-absorbing armpit crutch of this embodiment includes, from top to bottom, an armpit support 1, a hand grip 2, a support tube 3, and a support foot 4. The support tube 3 includes an adjusting outer tube 301, and the support foot 4 includes an adjusting inner tube 401, a shock-absorbing joint 402, a spring 403, a shock-absorbing inner sleeve 404, a foot tube 405, and a foot pad 406. The upper end of the adjusting inner tube 401 is fitted inside the adjusting outer tube 301, the shock-absorbing joint 402 is fitted inside the lower end of the adjusting inner tube 401, the shock-absorbing inner sleeve 404 is fitted inside the foot tube 405, the foot pad 406 is fitted inside the lower end of the foot tube 405, the shock-absorbing joint 402 is movably fitted inside the shock-absorbing inner sleeve 404, and the spring 403 is disposed inside the shock-absorbing inner sleeve 404, with one end abutting against the shock-absorbing joint 402 and the other end abutting against the shock-absorbing inner sleeve 404. This shock-absorbing armpit crutch includes an armpit support 1, a hand grip 2, a support tube 3, and a foot 4. When the foot 4 is assembled, the adjusting inner tube 401 and the shock-absorbing joint 402 are connected to form a floating part, while the shock-absorbing inner sleeve 404, the foot tube 405, and the foot pad 406 are connected to form a fixed part. A spring 403 is set inside the shock-absorbing inner sleeve 404. The shock-absorbing joint 402 and the shock-absorbing inner sleeve 404 can move relative to each other through the spring 403. This allows a portion of the ground's reaction force to be converted into the elastic potential energy of the spring 403 during the landing process of the foot 4, thus achieving shock absorption and cushioning of the armpit crutch. It provides good comfort and can effectively relieve armpit numbness and reduce the risk of armpit injury.

[0027] Preferably, the adjusting inner tube 401 has a first through groove 4011, the shock-absorbing joint 402 has a second through groove 4021, the shock-absorbing inner sleeve 404 has a first through hole 4041, the foot tube 405 has a second through hole 4051, and the first pin 5 is arranged to pass through the second through hole 4051, the first through hole 4041, the first through groove 4011 and the second through groove 4021 in sequence from the outside to the inside. In this embodiment, the adjusting inner tube 401 has a first through groove 4011, and the shock-absorbing joint 402 has a second through groove 4021. When the shock-absorbing joint 402 is fitted onto the lower end of the adjusting inner tube 401, the first through groove 4011 and the second through groove 4021 overlap and communicate. The shock-absorbing inner sleeve 404 has a first through hole 4041, and the foot tube 405 has a second through hole 4051. When the shock-absorbing inner sleeve 404 is fitted into the foot tube 405, the second through hole 4051 and the first through hole 4041 overlap and communicate. During assembly, the spring member 403 is placed in the inner cavity of the shock-absorbing inner sleeve 404. The shock-absorbing joint 402 is inserted into the shock-absorbing inner sleeve 404. The first pin 5 passes through the second through hole 4051, the first through hole 4041, the first through groove 4011 and the second through groove 4021 from the outside to the inside. This prevents the adjusting inner tube 401 and the shock-absorbing joint 402 from coming out of the shock-absorbing inner sleeve 404 and the foot tube 405. At the same time, the first pin 5 passes through the first through groove 4011 and the second through groove 4021, so that the adjusting inner tube 401 and the shock-absorbing joint 402 have a range of vertical movement relative to the shock-absorbing inner sleeve 404 and the foot tube 405, thereby enabling compression and shock absorption of the spring 403.

[0028] Preferably, a first height adjustment mechanism 6 is provided between the inner tube 401 and the outer tube 301. The inner tube 401 is provided with a first positioning through hole 7, and the outer tube 301 is provided with a plurality of first row holes 8. The first height adjustment mechanism 6 includes a first locking ball (not shown in the figure) and a first elastic reset member (not shown in the figure) disposed in the inner tube 401. The first elastic reset member is used to make the first locking ball pass through the first positioning through hole 7 and the first row holes 8. In this embodiment, the first locking pin passes through the first positioning through hole 7 and the first row of holes 8, keeping the inner adjusting tube 401 and the outer adjusting tube 301 in a locked state. When it is necessary to adjust the height of the branch tube 3, the first locking pin is pressed by the finger to cause the first elastic reset member to undergo elastic deformation and compression, thereby causing the first locking pin to exit the first row of holes 8. Then, the branch tube 3 is manually driven to extend or retract along the extension direction of the inner adjusting tube 401. After reaching the target height, the first locking pin passes through the first row of holes 8, thereby locking the position of the branch tube 3 on the inner adjusting tube 401, thus completing the height adjustment of the branch tube 3. This can meet the needs of patients of different heights, has high flexibility of use, and has a wide range of applications.

[0029] Preferably, the branch pipe 3 further includes a first bend 302 and a second bend 303 disposed on both sides of the adjusting outer pipe 301.

The locking mechanism 9 includes a second locking ball 901 and a second elastic reset member 902 disposed in the first inner sleeve 202 and the second inner sleeve 203. The second elastic reset member 902 is used to allow the second locking ball 901 to pass through the second positioning through hole 10 and the third positioning through hole 11. In this embodiment, the second locking ball 901 passes through the second positioning through hole 10 and the third positioning through hole 11, keeping the grip part 2 and the branch tube part 3 in a locked state. When it is necessary to separate the grip part 2 and the branch tube part 3, the second elastic reset member 902 is elastically deformed and compressed by pressing the second locking ball 901 with a finger, thereby causing the second locking ball 901 to exit the third positioning through hole 11, so that the first inner sleeve 202 and the second inner sleeve 203 can be pulled out from the first bend tube 302 and the second bend tube 303. The structure is simple and the operation is convenient.

[0031] Preferably, a second height adjustment mechanism 12 is provided between the grip 201 and the first inner sleeve 202 and the second inner sleeve 203.

In this embodiment, the second pin is a C-shaped pin, which can hold the first sleeve 13 tightly in the inserted state, providing good connection stability. When it is necessary to adjust the height of the grip 201, the second pin is first pulled out, and then the grip 201 is manually raised or lowered along the extension direction of the first inner sleeve 202 and the second inner sleeve 203. After reaching the target height, the second pin is reinserted into the first sleeve 13 and the second row of holes 14 to lock the position of the grip 201 on the first inner sleeve 202 and the second inner sleeve 203, thereby completing the height adjustment of the grip 201. This can meet the needs of patients of different heights, providing high flexibility and wide applicability.

[0032] Preferably, the armpit support 1 includes an armpit support 101 and a first outer sleeve 102 and a second outer sleeve 103 disposed on the lower side of the armpit support 101. The upper end of the first inner sleeve 202 is fitted inside the first outer sleeve 102, and the upper end of the second inner sleeve 203 is fitted inside the second outer sleeve 103, so that the armpit support 1 and the hand grip 2 can be detachably connected, which is convenient for disassembly and storage and further reduces the space occupied.

[0033] Preferably, a third height adjustment mechanism 15 is provided between the first inner sleeve 202 and the first outer sleeve 102, and between the second inner sleeve 203 and the second outer sleeve 103. A second sleeve 16 is sleeved on the lower end of the first outer sleeve 102 and the second outer sleeve 103.
