[0028] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the disclosure of the present invention.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] See also Figures 1-11 As shown in the figure, an embodiment of the present invention provides a shock-absorbing cane, which includes a lower limb assembly 1. The lower limb assembly 1 includes a lower limb tube 11, a middle limb tube 12 and a seven-shaped frame 13. The lower limb tube 11 is sleeved in the middle limb tube 12, and the connection between the lower limb tube 11 and the middle limb tube 12 is fixed by a locking nut 14. The top of the middle limb tube 12 is connected to the seven-shaped frame 13, and a shock-absorbing assembly 15 is arranged between the top of the middle limb tube 12 and the seven-shaped frame 13.

[0031] By arranging a shock-absorbing component between the middle limb tube and the seven-shaped frame, the lower limb component has a shock-absorbing function, which improves the comfort of use and reduces fatigue during use.

[0032] Among them, as a specific implementation method, the shock absorption assembly 15 includes an open sleeve 151, a thin-walled sleeve 152, a spring 153, a locking screw 154, and a locking nut 155. The spring 153 is arranged in the cavity at the lower end of the seven-character frame 13, and the top of the spring 153 abuts the top wall of the cavity. The thin-walled sleeve 152 is sleeved on the outer wall of the top end of the middle limb tube 12. The top end of the middle limb tube 12 is provided with a vertical long through hole 121. The open end of the open sleeve 151 is downward and sleeved on the top end of the middle limb tube. The top end of the open sleeve 151 is embedded in the cavity and abuts against the bottom end of the spring 153. The locking screws 154 pass through the thin-walled sleeve 152, the open sleeve 151, the lower end of the seven-character frame 13 and the vertical long through hole 121, and cooperate with the locking nut 155 to achieve the fixation of the seven-character frame 13 and the middle limb tube 12.

[0033] During use, the seven-shaped frame is pressed down by force, compressing the spring, and utilizing the reverse force of the spring's own reset to act on the seven-shaped frame, providing a buffering and shock-absorbing effect.

[0034] Among them, as a possible implementation scheme, a plurality of interconnected through holes 122 are arranged at intervals in the vertical direction of the middle limb tube 12, and the lower limb tube 11 is provided with marbles 111, so that the height adjustment of the lower limb component can be achieved through the cooperation between the marbles 111 and the through holes 122.

[0035] Among them, in order to improve the force balance of the lower limb tube and the middle limb tube after height adjustment, the lower limb tube is equipped with double marbles, which are fixed with the through holes from two opposite directions, and can also effectively prevent the lower limb tube and the middle limb tube from being damaged by unidirectional force.

[0036] Among them, in one possible implementation scheme, the lower end of the lower limb tube 11 is further provided with a rubber foot 2. The design of the rubber foot can further enhance the shock absorption effect of the lower limb assembly, and can also effectively prevent the lower limb tube from being damaged by long-term friction with the ground, thereby extending the service life of the product.

[0037] In addition, a circular hole 123 is provided at the top of the middle limb tube (see Figure 5 As shown in the figure, the seven-shaped frame 13 and the middle limb tube 12 are fixed by respectively passing the locking screws through the thin-walled sleeve, the open sleeve, the lower end of the seven-shaped frame and the circular hole, and cooperating with the locking nuts. When fixed through the circular hole, there is no space for relative downward or upward movement. Therefore, the product in this assembled state has no shock absorption effect. Through this structural design, it is possible to switch between the shock absorption effect and the non-shock absorption effect at will to meet the needs of different usage scenarios.

[0038] Among them, in a possible implementation, the shock-absorbing walking stick also includes an axillary crutch upper limb component 3 or an elbow crutch upper limb component 4, and the axillary crutch upper limb component 3 or the elbow crutch upper limb component 4 is connected to the upper end of the seven-character cross.

[0039] By connecting the axillary crutch upper limb assembly to the upper end of the seven-shaped frame, or connecting the elbow crutch upper limb assembly to the upper end of the seven-shaped frame, the lower limb assembly can be conveniently converted from a single crutch to an axillary crutch or an elbow crutch, thereby achieving a multifunctional walking stick effect.

[0040] To facilitate the secure connection of the axillary crutch upper limb assembly or the elbow crutch upper limb assembly, the upper end of the seven-shaped frame is slotted and the outer wall of the upper end is provided with an external thread. A locking nut cooperates with the external thread to tighten the axillary crutch upper limb assembly or the elbow crutch upper limb assembly. The locking nut cooperates with the external thread to gradually tighten the slot, thereby squeezing the axillary crutch upper limb assembly or the elbow crutch upper limb assembly.

[0041] As a specific implementation method, see Figure 8-Figure 9 As shown, the axillary crutch upper limb assembly 3 includes an axillary crutch upper limb tube 31, an axillary crutch adjustment tube 32 and an axillary support 33. The lower end of the axillary crutch adjustment tube 32 is sleeved and fixed in the axillary crutch upper limb tube 31, and the top of the axillary crutch adjustment tube 32 is fixed with an axillary support 33.

[0042] In order to facilitate the height adjustment of the axillary crutch, a plurality of interconnected through holes 122 are arranged at intervals in the vertical direction of the axillary crutch upper limb tube, and the lower end of the axillary crutch adjustment tube 32 is provided with a marble 111, so that the height adjustment of the axillary support upper limb assembly can be achieved through the cooperation of the marble 111 and the through hole 122.

[0043] Through the through hole on the upper limb tube of the axillary crutch and the marble design at the lower end of the axillary crutch adjustment tube, the height of the axillary crutch can be easily adjusted to meet the needs of different users.

[0044] Among them, in order to facilitate the force balance of the armpit support, the lower end of the armpit crutch adjustment tube is equipped with double marbles, which cooperate with the through holes in two opposite directions to achieve fixation of the armpit support after height adjustment.

[0045] In addition, for easy assembly, the top of the armpit crutch adjustment tube is fixed to the armpit support 33 by a rivet 35. And to improve the comfort of use, the armpit support is also designed with an armpit support pad 34. Among them, the armpit support pad is preferably made of a soft material, such as a sponge pad or latex pad.

[0046] As a specific implementation method, see Figure 10-11 The elbow crutch upper limb assembly 4 includes an elbow crutch upper limb tube 41, an elbow crutch adjustment tube 42, a cross-hand joint 43 and a cross-hand 44. The lower end of the elbow crutch adjustment tube 42 is sleeved and fixed in the elbow crutch upper limb tube 41, the upper end of the elbow crutch adjustment tube 42 is fixed with the cross-hand joint 43, and the cross-hand 44 is fixed on the cross-hand joint 43.

[0047] In order to facilitate the height adjustment of the elbow crutch, a plurality of interconnected through holes 122 are arranged at intervals in the vertical direction of the upper limb tube of the elbow crutch, and the lower end of the elbow crutch adjustment tube 42 is provided with a marble 111 to achieve the height adjustment of the upper limb component of the elbow crutch through the cooperation of the marble and the through hole.

[0048] During actual use, the elbow crutch will not be directly subjected to force. Therefore, the lower end of the elbow crutch adjustment tube is provided with a single marble, which cooperates with the through hole to achieve fixation after height adjustment.

[0049] Among them, as a specific implementation method, in order to facilitate the connection of product components, the upper end of the elbow crutch adjustment tube 42 is fixed to the cross-arm joint 43 by a rivet.

[0050] In order to facilitate the storage and deployment of the cross-arm, the cross-arm 44 is rotatably connected to the cross-arm joint 43 via a screw 45, so that it can be turned up or down around the screw for easy storage when the elbow crutch is not in use.

[0051] From the above detailed description of the shock-absorbing cane of the present invention in combination with the drawings in the specification, it can be understood that the shock-absorbing cane of the present invention has a lower limb assembly with a shock-absorbing assembly, so that the lower limb assembly has a shock-absorbing function. When the lower limb assembly is used as a single crutch, the use process has a shock-absorbing effect, which makes the use more comfortable and reduces the user's fatigue.

[0052] When the shock absorption function is not needed, just switch to the round hole connection and it can be used as a regular crutch. The convenient switch can meet the needs of different usage scenarios.

[0053] When the axillary crutch upper limb assembly is assembled on the lower limb assembly, the cane of the utility model can be switched to an axillary crutch for use. When the axillary crutch upper limb assembly is removed and the elbow crutch upper limb assembly is assembled on the lower limb assembly, the cane can be switched back to an elbow crutch for use. Since both the axillary crutch upper limb assembly and the elbow crutch upper limb assembly are connected by plugging and locking with a nut, switching between canes with different functions is convenient and quick. The cane of the utility model can be freely switched from an elbow crutch form, an axillary crutch form, or a medical single crutch form, thereby meeting the requirements of a simple structure with diverse functions and saving usage costs. Furthermore, the cane has a shock-absorbing effect in different crutch forms, making it comfortable to use.

[0054] Moreover, the height of different crutch forms can be easily adjusted to meet the height requirements of different users, and the scope of application is wider.

[0055] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
