[0002] A crutch is an important medical rehabilitation aid, which is mainly divided into a walking stick, an elbow cane and an axillary cane. A walking stick is mainly used to meet the user's mild needs, such as the elderly or climbers. A walking stick is not a disability product, while an elbow cane is a moderate lower limb disability product. An axillary cane is a necessity for people with severe lower limb disabilities or leg injuries. Most people with lower limb disabilities have to use axillary canes for life.

[0003] In the process of using the existing crutches, most of them use the foot pads at the bottom of the crutches to achieve the effect of shock absorption, so as to relieve the user's discomfort. However, it is obviously not enough to achieve shock absorption only by the foot pads, and ordinary foot pads obviously cannot provide sufficient shock absorption effect. In addition, when using the crutches, the user does not always apply force to the crutches vertically. When the user tilts the crutches, if only the foot pads are used to achieve shock absorption, it is difficult to achieve shock absorption and support at the same time. Therefore, it is not comfortable to use, the safety is poor, and the user does not get a good use experience. Utility Model Content

[0004] The utility model aims to provide a telescopic shock-absorbing crutch, aiming to solve the problems of poor shock-absorbing effect and difficulty in achieving both shock-absorbing effect and supporting effect in the existing crutch.

[0031] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0034] Combine the following Figures 1 to 4 The utility model describes a telescopic shock-absorbing crutch.

[0035] like Figures 1 to 4 As shown, the utility model provides a telescopic shock-absorbing crutch, comprising a support tube 1, a handle 2, a connecting tube 3, a support column 4, a foot pad 5 and an elastic member 6.

[0036] Among them, the handle 2 is connected to the upper end of the support tube 1, and the connecting tube 3 is connected to the lower end of the support tube 1. Specifically, the lower end of the support tube 1 is inserted into the interior of the connecting tube 3 and the two are interference fit, so the connection structure is more stable.

[0037] Furthermore, the support column 4 is connected to the lower end of the connecting tube 3, the foot pad 5 is sleeved on the connecting tube 3 and can move axially along the support tube 1, that is, the foot pad 5 can move up and down relative to the connecting tube 3, and one end of the elastic member 6 is connected to the foot pad 5.

[0038] In the telescopic shock-absorbing crutch provided by the utility model, the foot pad 5, the support tube 1 and the handle 2 are used to provide the most basic support function for the user. By arranging the elastic member 6, when the user presses the crutch hard, the elastic member 6 can have a good shock-absorbing effect. Compared with the existing shock-absorbing method that only relies on the foot pad 5, the shock-absorbing effect is better.

[0039] In the telescopic shock-absorbing crutch provided by the present invention, when the user tilts the crutch to use the crutch, that is, when the user applies force to the crutch at an angle, the foot pad 5 will move toward the side closer to the user relative to the support tube 1, that is, move obliquely upward. At this time, the elastic member 6 has played a good shock-absorbing effect. If there is no support column 4, the crutch and the ground are supported only by a small contact surface of the foot pad 5, and the supporting effect is not good. However, by providing the support column 4, after the foot pad 5 moves up, the bottom surface of the foot pad 5 is higher than the bottom surface of the support column 4, the support column 4 will expose the bottom of the foot pad 5 and contact the ground, and the supporting point between the crutch and the ground is provided by the foot pad 5 and the support column 4, which greatly improves the supporting effect of the crutch. Therefore, the crutch can provide a good shock-absorbing effect while also providing a good supporting effect for the user, that is, it has both good shock-absorbing and supporting effects, is more comfortable to use, and is safer, and the user can get a better use experience.

[0040] It can be understood that even when the user applies vertical force to the crutch, the foot pad 5 will move upward, and the support column 4 can be exposed to play a supporting role. The crutch can provide a good shock-absorbing effect while also providing a good supporting effect for the user, that is, it has both good shock-absorbing and supporting effects, which makes it more comfortable and safer to use, and the user can get a better use experience.

[0041] In some embodiments, a receiving groove is provided inside the foot pad 5, and the connecting tube 3 has a limiting portion 31. The limiting portion 31 protrudes from the outer wall of the connecting tube 3 along the radial direction of the connecting tube 3, and the limiting portion 31 is located in the receiving groove. The elastic member 6 is located in the receiving groove. One end of the elastic member 6 abuts against the limiting portion 31, and the other end of the elastic member 6 abuts against the foot pad 5. Specifically, the receiving groove is used to provide a space for placing the elastic member 6, and the limiting portion 31 serves to limit the range of movement of the elastic member 6, so that the elastic member 6 can apply elastic force to the foot pad 5 more stably, thereby achieving a shock-absorbing effect. At the same time, it also facilitates the foot pad 5 to return to its original position, making it more convenient to use.

[0042] In some embodiments, the foot pad 5 includes a connecting member 51 and a supporting member 52. The supporting member 52 is threadedly connected to the connecting member 51. A receiving groove is formed between the connecting member 51 and the supporting member 52. The lower end of the elastic member 6 abuts against the upper end of the supporting member 52. The upper end of the elastic member 6 abuts against the lower side surface of the limiting portion 31. The connecting member 51 serves to connect with the connecting pipe 3. The supporting member 52 mainly contacts the ground to provide support. The supporting member 52 is prone to wear during long-term use. The supporting member 52 is connected to the connecting member 51 by threaded connection, which facilitates the disassembly and replacement of the supporting member 52, reduces the cost of use, and provides a better user experience.

[0043] In some embodiments, the connecting member 51 has a stop portion 53, which is a step structure. The stop portion 53 abuts against the upper side surface of the limiting portion 31 and the upper end portion of the connecting tube 3. Specifically, the elastic member 6 can drive the entire foot pad 5 to maintain a downward movement trend, and the stop portion 53 in the connecting member 51 can prevent the entire foot pad 5 from continuing to move downward, thereby improving the structural stability of the overall structure.

[0044] In some embodiments, the support member 52 has three supporting feet. Specifically, the support member 52 is shaped like a claw as a whole, which can reduce the weight of the entire structure while ensuring the supporting effect, thereby reducing the weight of the entire crutch, making the entire crutch lighter, and providing the user with a better experience.

[0045] In some other embodiments, the support member 52 may also have four supporting legs, which can also reduce the weight of the entire structure while ensuring the supporting effect. It can be understood that the number of supporting legs can be changed according to actual needs.

[0046] In some embodiments, a hollow structure is provided in the middle of the supporting foot to further reduce the weight, making the entire crutch lighter.

[0047] In some embodiments, an anti-skid pad 7 is provided at the bottom of the supporting foot. Specifically, the anti-skid pad 7 is a rubber pad, which can provide a certain shock-absorbing effect and also has good anti-skid performance.

[0048] In some embodiments, the bottom surfaces of the support column 4 and the anti-slip pad 7 are both provided with anti-slip patterns, which provide a better anti-slip effect, improve the stability of the crutch when in use, and thus improve the safety of use.

[0049] In some other embodiments, the bottom of the support column 4 is also provided with an anti-skid pad 7 made of a rubber pad, which can provide a certain shock-absorbing effect and also has good anti-skid performance.

[0050] In some embodiments, a mounting protrusion 32 is provided at the bottom of the connecting pipe 3, and the supporting column 4 is snap-connected to the mounting protrusion 32 for easy disassembly and replacement.

[0051] In some embodiments, the bottom surface of the support column 4 is a spherical surface. When the crutch is used at an angle, the support column 4 can still provide support for the crutch, and the support effect is better.

[0052] In some embodiments, the elastic member 6 is a spring, which has good elasticity and can provide a good shock-absorbing effect for the crutch.

[0053] In some embodiments, the support tube 1 is a telescopic tube, which has the function of telescoping and folding, and is more convenient to use.

[0054] The above description is only 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 using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
