Description

Technical Field

[0001] This utility model relates to the field of assistive walking equipment technology, specifically a quick-release underarm crutch. Background Technology

[0002] Assistive walking devices are instruments used for disease diagnosis, treatment, monitoring, or rehabilitation, and underarm crutches are one of them. Underarm crutches are also common walking aids. By supporting the armpit and hand gripping the handle, they distribute the weight of the lower limbs, helping people with mobility impairments maintain balance and reduce leg pressure. They are suitable for short-term or temporary mobility assistance.

[0003] During the design process of this utility model, the following problems were discovered in the existing technology:

[0004] Most underarm crutches on the market are fixed installations, requiring tools and complicated steps for users to adjust the height or disassemble them. This results in time-consuming disassembly, large storage volume, and is not conducive to emergency transport or use in multiple scenarios. It also makes it difficult to quickly adjust the length to fit in emergency situations, resulting in low applicability and lack of flexibility for underarm crutches. Utility Model Content

[0005] The purpose of this invention is to provide a quick-release underarm crutch to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-release underarm crutch, including an underarm support, a support frame threaded onto the bottom of the underarm support, a connecting rod threaded onto the bottom of the support frame, the underarm support including a fixed base, a first fixed opening fixedly installed on the top of the fixed base, a slot opened on the top of the fixed base, a pin slidably installed on the inner wall of the slot, a base plate slidably installed on the top of the fixed base, two first support rods threaded onto the bottom of the fixed base, a first through hole opened on the outer surface of the first support rod, a threaded hole opened on the top of each first support rod, a second screw slidably installed inside the first through hole, a first nut threaded onto one end of the second screw, a fixing groove slidably installed on the outer surface of the second screw, an outer rod fixedly installed at the bottom of the fixing groove, five second through holes opened on the outer surface of the outer rod, and an inner rod slidably installed on the inner wall of the outer rod.

[0007] More preferably, each of the first fixing openings has a first screw installed in its internal thread.

[0008] More preferably, a sponge pad is fixedly installed on the top of the base plate.

[0009] More preferably, each of the first support rods has a second fixing hole on its outer surface.

[0010] More preferably, the same handle is slidably mounted on the inner wall of each of the second fixing openings.

[0011] More preferably, the outer surface of the inner rod is provided with a third through hole.

[0012] More preferably, a third screw is slidably mounted on the inner wall of the third through hole, and a second nut is threaded onto one end of the third screw.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This underarm crutch uses a first screw and threaded holes at the top of the two first support rods to install the two first support rods together with the underarm support. At the same time, the second screw, first nut, third screw, and second nut work together to ensure that the patient's body is supported while allowing for quick disassembly and storage. This meets the needs of emergency transport or daily storage, improves the portability and operational efficiency of the underarm crutch, and enhances its flexibility. Attached Figure Description

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a quick-release underarm cane, including an underarm support 1, a support frame 2 threadedly installed at the bottom of the underarm support 1, a connecting rod 3 threadedly installed at the bottom of the support frame 2, the underarm support 1 including a fixed base 11, a first fixing opening 12 fixedly installed at the top of the fixed base 11, a slot 13 opened at the top of the fixed base 11, a pin 14 slidably installed on the inner wall of the slot 13, a base plate 15 slidably installed at the top of the fixed base 11, and two second pins 14 threadedly installed at the bottom of the fixed base 11. A support rod 21 has a first through hole 22 on its outer surface. Each first support rod 21 has a threaded hole 23 at its top. A second screw 31 is slidably installed inside the first through hole 22. A first nut 32 is threaded onto one end of the second screw 31. A fixing groove 33 is slidably installed on the outer surface of the second screw 31. An outer rod 34 is fixedly installed at the bottom of the fixing groove 33. Five second through holes 35 are opened on the outer surface of the outer rod 34. An inner rod 36 is slidably installed on the inner wall of the outer rod 34.

[0022] In this embodiment, as Figure 1 and Figure 2 As shown, each of the first fixing openings 12 has a first screw 16 installed in its internal thread.

[0023] In this embodiment, as Figure 1 and Figure 2 As shown, a sponge pad 17 is fixedly installed on the top of the base plate 15.

[0024] In this embodiment, as Figure 1 and Figure 3 As shown, each first support rod 21 has a second fixing hole 24 on its outer surface.

[0025] In this embodiment, as Figure 1 and Figure 3 As shown, the same handle 25 is slidably installed on the inner wall of each second fixed opening 24.

[0026] In this embodiment, as Figure 1 and Figure 4 As shown, a third through hole 37 is provided on the outer surface of the inner rod 36.

[0027] In this embodiment, as Figure 1 and Figure 4 As shown, a third screw 38 is slidably installed on the inner wall of the third through hole 37, and a second nut 39 is threaded onto one end of the third screw 38.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the quick-release underarm cane operates as follows:

[0029] To disassemble the underarm crutch, the user simply slides the base plate 15 to slide the pin 14 out of the slot 13 at the top of the fixed base 11. Then, the user rotates the first screw 16 to remove it. Afterward, the user can separate the fixed base 11 from the two first support rods 21. Without the constraint of the fixed base 11 and the first screw 16, the user can directly remove the handle 25. Next, the user rotates the second screw 31 to separate the first nut 32 from the second screw 31. Then, the user pulls the second screw 31 out of the fixing slot 33. Finally, the user can separate the connecting rod 3 from the two first support rods 21. This completes the disassembly of the underarm crutch. If the user needs to reassemble it later, they simply insert the two first support rods 21... After inserting the first screw 31 into the fixing groove 33, align the first through holes 22 on the outer surfaces of the two first support rods 21 with each other. Then, after inserting the second screw 31 through the fixing groove 33 and the two first support rods 21, rotate the first nut 32 to thread the first nut 32 onto one end of the second screw 31. Then, slide the handle 25 into the second fixing hole 24. Then, install the fixing base 11 on the top of the first support rod 21 with the first screw 16. Then, insert the pin 14 into the slot 13. The user can then adjust the overall height of the connecting support rod 3 according to the patient's height. The user only needs to pull the inner rod 36 until the height is appropriate, align the third through hole 37 with the second through hole 35, and then pass the third screw 38 through the second through hole 35 and the third through hole 37. Finally, thread the second nut 39 onto one end of the third screw 38.
