Technical Field
[0001] This utility model relates to the field of assistive device technology, specifically to a shock-absorbing cane. Background Technology
[0002] With economic development and social progress, the comfort and ease of use of assistive devices have received widespread attention, and canes are no exception, increasingly developing towards features such as multifunctionality, ease of use, space saving, and safety and comfort.
[0003] Typically, canes are made of a single aluminum or iron tube, which limits their functionality. To achieve shock absorption, most existing canes have shock-absorbing springs installed on the outside of the leg tube. However, because the shock-absorbing springs are exposed, items such as trouser legs and shoelaces can easily get caught in them while walking. Moreover, using large-sized springs on the outside increases the weight of the cane, making it less convenient to use. Utility Model Content
[0004] (I) This utility model provides a shock-absorbing cane, which alleviates the technical problem in the prior art where the shock-absorbing spring is exposed on the outside of the foot tube, which causes the user's clothing to be caught and is not convenient to use.

[0006] To solve the above-mentioned technical problems, embodiments of this utility model provide a shock-absorbing cane, including a support body, a foot tube mechanism, and an elastic reset mechanism;
[0007] The foot tube mechanism includes a shock-absorbing foot tube and a sliding lower foot tube. One end of the shock-absorbing foot tube is located inside the bottom end of the support body, and the sliding lower foot tube is installed inside the other end of the shock-absorbing foot tube. The sliding lower foot tube can slide inside the shock-absorbing foot tube along the extension direction of the shock-absorbing foot tube.
[0008] The elastic reset mechanism is located inside the shock-absorbing foot tube, and its bottom end is connected to the top end of the sliding lower foot tube. When the support body presses down on the foot tube mechanism, the elastic reset mechanism causes the shock-absorbing foot tube to have a tendency to reset.
[0009] Furthermore, the shock-absorbing foot tube has symmetrically formed connecting holes along its own radial direction, and the sliding lower foot tube has symmetrically formed waist-shaped holes along its own radial direction. The sliding member passes through the connecting holes and the waist-shaped holes in sequence, and the sliding member can slide along the extension direction of the waist-shaped holes.
[0010] Furthermore, the shock-absorbing foot tube is also symmetrically provided with fixing holes along its own radial direction. The fixing holes are located above the connecting holes. The top end of the elastic reset mechanism is provided with a first through hole. After the fixing member passes through the fixing hole and the first through hole in sequence, one end of the elastic reset mechanism is fixed to the shock-absorbing foot tube.
[0011] Furthermore, the elastic reset mechanism includes a fixing component and an elastic element. The fixing component is located at both ends of the elastic element and is fixed to the shock-absorbing foot tube and the sliding lower foot tube, respectively.
[0012] Furthermore, the fixing component includes an upper fixing seat and a lower fixing seat, which are respectively disposed at the top and bottom of the elastic element. The upper fixing seat is fixed to the inner wall of the shock-absorbing foot tube, and the lower fixing seat is disposed at the top of the sliding lower foot tube and can move synchronously with the sliding lower foot tube.
[0013] Furthermore, the first through hole is formed in the upper fixing seat, and the fixing member passes through the shock-absorbing foot tube and the upper fixing seat in sequence to fix the upper fixing seat to the shock-absorbing foot tube.
[0014] Furthermore, the bottom of the shock-absorbing foot tube is also equipped with a hollow sleeve, the inner wall of the hollow sleeve is in contact with the outer wall of the shock-absorbing foot tube, and the sliding lower foot tube passes through the hollow sleeve and is connected to the shock-absorbing foot tube.
[0015] Furthermore, the bottom end of the support body is provided with a plurality of adjustment holes, which are spaced apart along the extension direction of the support body. The top end of the shock-absorbing foot tube is provided with a second through hole symmetrically along its own radial direction. The adjustment component passes through the adjustment hole and the second through hole in sequence to fix the shock-absorbing foot tube to the support body.
[0016] Furthermore, the bottom of the sliding lower leg tube is provided with a foot pad.
[0017] Furthermore, the bottom of the foot pad is provided with an anti-slip part.
[0018] The beneficial effects of this utility model are:
[0019] This utility model provides a shock-absorbing cane, including a support body, a foot tube mechanism, and an elastic reset mechanism. The foot tube mechanism includes a shock-absorbing foot tube and a sliding lower foot tube. The sliding lower foot tube can slide inside the shock-absorbing foot tube along its extension direction and is located inside the bottom end of the support body, thus connecting the support body and the foot tube mechanism together. The elastic reset mechanism is located inside the shock-absorbing foot tube, and its bottom end is connected to the top tube of the sliding lower foot tube. When the support body presses down on the foot tube mechanism, it causes the shock-absorbing foot tube to move downward, thereby changing the relative position between the shock-absorbing foot tube and the sliding lower foot tube, and thus compressing the elastic reset mechanism located inside the shock-absorbing foot tube. The elastic reset mechanism gives the shock-absorbing foot tube a tendency to reset and generates a certain rebound force when the support body is lifted, forming a comfortable shock-absorbing and buffering effect, making it very convenient to use. At the same time, since the elastic reset mechanism is located inside the shock-absorbing foot tube, it can effectively prevent the user's clothing from being caught during use, improving the comfort of use.

[0031] like Figures 1 to 3 As shown, this utility model provides a shock-absorbing cane, including a support body 100, a foot tube mechanism 200, and an elastic reset mechanism 300. The foot tube mechanism 200 includes a shock-absorbing foot tube 201 and a sliding lower foot tube 202. One end of the shock-absorbing foot tube 201 is located inside the bottom end of the support body 100, and the other end of the shock-absorbing foot tube 201 is equipped with a sliding lower foot tube 202. The sliding lower foot tube 202 can slide inside the shock-absorbing foot tube 201 along its extension direction. The elastic reset mechanism 300 is located inside the shock-absorbing foot tube 201, and its bottom end is connected to the top end of the sliding lower foot tube 202. When the support body 100 presses down on the foot tube mechanism 200, the elastic reset mechanism 300 causes the shock-absorbing foot tube 201 to have a tendency to reset.
[0032] In this embodiment, the shock-absorbing cane includes a support body 100, a foot tube mechanism 200, and an elastic reset mechanism 300. The foot tube mechanism 200 includes a shock-absorbing foot tube 201 and a sliding lower foot tube 202. The sliding lower foot tube 202 can slide inside the shock-absorbing foot tube 201 along the extending direction of the shock-absorbing foot tube 201. The shock-absorbing foot tube 201 is located inside the bottom end of the support body 100, thereby connecting the support body 100 and the foot tube mechanism 200 together. The elastic reset mechanism 300 is located inside the shock-absorbing foot tube 201, and its bottom end is also connected to the top tube of the sliding lower foot tube 202. When the support body 100 presses down on the foot tube mechanism... When the structure 200 is in operation, it causes the shock-absorbing foot tube 201 to move downward, thereby changing the relative position between the shock-absorbing foot tube 201 and the sliding lower foot tube 202. This compresses the elastic reset mechanism 300 located inside the shock-absorbing foot tube 201. The elastic reset mechanism 300 gives the shock-absorbing foot tube 201 a tendency to reset, and when the support body 100 is lifted, it generates a certain rebound force, forming a comfortable shock absorption and cushioning effect. It is very convenient to use. At the same time, since the elastic reset mechanism 300 is located inside the shock-absorbing foot tube 201, it can effectively prevent the user's clothing from being caught during use, thus improving the comfort of use.
[0033] According to one embodiment provided by this utility model, such as Figure 1 and Figure 2 As shown, the shock-absorbing foot tube 201 has a connecting hole 203 symmetrically opened along its own radial direction, and the sliding lower foot tube 202 has a waist-shaped hole 204 symmetrically opened along its own radial direction. The sliding member 205 passes through the connecting hole 203 and the waist-shaped hole 204 in sequence, and the sliding member 205 can slide along the extension direction of the waist-shaped hole 204.
[0034] In this embodiment, the shock-absorbing foot tube 201 has symmetrically opened connecting holes 203 along its own radial direction. Correspondingly, the sliding lower foot tube 202 has symmetrically opened waist-shaped holes 204 along its own radial direction. The sliding member 205 passes through the connecting holes 203 and the waist-shaped holes 204 in sequence and is then fixed. When the user moves and presses down on the support body 100, the sliding member 205 can slide along the extension direction of the waist-shaped holes 204, which will cause the shock-absorbing foot tube 201 to slide relative to the sliding lower foot tube 202, thereby compressing the elastic reset mechanism 300. After the movement is pressed, the elastic reset mechanism 300 will generate a real upward thrust and generate a certain rebound effect when the support body 100 is lifted, forming a comfortable shock-absorbing and buffering effect, and realizing the overall shock absorption function of gentle pressure and easy rebound thrust.
[0035] Preferably, the sliding member 205 is set as a rivet.
[0036] According to one embodiment provided by this utility model, such as Figure 1 and Figure 2As shown, the shock-absorbing foot tube 201 is also symmetrically provided with fixing holes 206 along its own radial direction. The fixing holes 206 are located above the connecting holes 203. The top of the elastic reset mechanism 300 is provided with a first through hole. After the fixing member 207 passes through the fixing hole 206 and the first through hole in sequence, it fixes one end of the elastic reset mechanism 300 to the shock-absorbing foot tube 201.
