DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] like Figures 1-9 As shown, the utility model provides a suction cup patterned anti-slip cover, comprising: a cover body 3, the top of the cover body 3 is provided with an elastic opening 35 and an accommodating cavity 34 arranged inside, the elastic opening 35 is connected to the accommodating cavity 34; the bottom of the cover body 3 is provided with an anti-slip surface 31, and the surface of the anti-slip surface 31 is provided with a plurality of cylindrical suction cup-shaped anti-slip blocks 32.

[0031] The design of the elastic opening 35 enables the anti-slip cover to be easily connected to the bare rod of the crutch or other crutch with a rubber foot pad 4. The user only needs to put the elastic opening 35 of the anti-slip cover on the bare rod or other foot pad at the bottom of the crutch to achieve a stable connection and ensure that it will not fall off easily during use. In this embodiment (such as Figure 5 As shown), the accommodating cavity 34 can be made into a variety of shapes and sizes to accommodate rubber foot pads 4 of various shapes and sizes. Figures 6-10 The accommodating cavity 34 can be made into a shape that can accommodate the direct entry of the polished rod at the bottom of the crutch. There can be multiple polished rods at the bottom of the crutch, and multiple anti-slip sleeves can be installed on the multiple polished rods to increase the contact area with the ground and improve stability.

[0032] The adjustable design inside the accommodating cavity makes the anti-slip cover compatible with various types of other foot pads. Whether it is a smaller portable crutch or a larger support crutch, users can choose the appropriate anti-slip cover according to actual usage. This flexibility allows the product to adapt to the needs of different users, which not only improves the versatility of the product, but also provides users with more choices. In some embodiments (not shown in the figure), the anti-slip cover can also be applied to other equipment that requires anti-slip, such as walkers, industrial equipment, etc., further enhancing the market competitiveness of the product.

[0033] like Figure 3-Figure 5 as well as Figures 8-10 As shown, the anti-slip block 32 is roughly cylindrical, with the center of the anti-slip block 32 recessed inward to form a suction cup shape. Multiple anti-slip blocks 32 are evenly distributed axially along the center of the anti-slip surface 31. In this embodiment (not shown), the anti-slip block 32 is made of a non-slip and wear-resistant material, such as polyurethane, synthetic rubber, or any other desired material. The design of these anti-slip blocks 32 not only increases the contact area with the ground, but also, through its unique suction cup shape, can generate stronger grip when contacting the ground. When the user walks on wet or slippery ground, the anti-slip block 32 can effectively adhere to the ground, significantly increasing friction and reducing the risk of slipping.

[0034] In addition, the center of the anti-slip block 32 is provided with at least three drainage grooves 33. These three drainage grooves 33 extend outward from the middle of the anti-slip block 32, with the angle between any two of these drainage grooves 33 being 120°. In this embodiment, the three drainage grooves 33 divide the cylindrical anti-slip block 32 into three equal parts. In some embodiments (not shown), four drainage grooves 33 or any other desired number of drainage grooves 33 may be provided. The design of the drainage grooves 33 allows for rapid drainage of moisture in humid environments, ensuring direct contact between the anti-slip block 32 and the ground, further enhancing the anti-slip effect. This design allows users to use crutches with confidence even in humid environments, improving safety and comfort.

[0035] Specifically, the user attaches the sleeve 3 to the base of other crutches with rubber feet 4, or directly to the base of the rod assembly 2. An interference fit is employed between the sleeve 3 and the rubber feet 4, as well as between the sleeve and the rod assembly 2, creating a secure connection and preventing it from easily falling off during use. When the anti-slip block 32 contacts the ground and bears weight, the elastic properties of the material cause the anti-slip block 32 to deform under the pressure. The edges of the anti-slip block 32 compress downward, while the center concave inward, forming a "claw"-like structure. This shape change allows the anti-slip block 32 to better adapt to uneven surfaces, thereby increasing friction. When used in wet environments or on slippery surfaces, the slight deformation of the anti-slip block 32 effectively locks it into place, providing a stronger grip and preventing slipping. Furthermore, when used in wet environments, the drainage groove 33 allows water to quickly drain out of the groove, ensuring that the anti-slip block 32 maintains direct contact with the ground, further enhancing grip.

[0036] like Figure 1-Figure 2 and Figure 6-Figure 7 As shown, the present invention also provides a crutch comprising: a rod assembly 2 and a crutch head assembly 1 disposed at the upper end of the rod assembly 2, with an anti-slip sleeve connected to the lower end of the rod assembly 2. The rod assembly 2 comprises a fixed rod 21, a telescopic rod 22, and a locking device. The fixed rod 21 and the telescopic rod 22 are hollow tubes, with the telescopic rod 22 being slightly smaller than the fixed rod 21. The telescopic rod 22 is sleeved within the fixed rod 21 and locked by the locking device. The locking device comprises a plurality of locking holes 23 disposed along the length of the fixed rod 21, and a spring pin 24 disposed within the telescopic rod 22 and capable of being inserted into the locking holes 23 to lock the fixed rod 21.

[0037] The fixed rod 21 and telescopic rod 22 are typically made of high-strength alloy or other durable materials to ensure they are less susceptible to deformation or damage during prolonged use. The contact surfaces of the fixed rod 21 and telescopic rod 22 are also specially treated to prevent rust after prolonged use and to prevent accidents caused by hand slippage during use. Both the fixed rod 21 and telescopic rod 22 are hollow tubes. This hollow tubular design reduces production costs, further reduces the overall weight of the crutch, and improves user comfort.

[0038] Specifically, pressing the spring pin 24 unlocks the telescopic rod 22 from the fixed rod 21. The spring pin 24 contracts and disengages the locking hole 23, allowing the entire spring pin 24 to slide up and down relative to the fixed rod 21 to adjust the crutch's height. After adjusting to the desired height, the spring pin 24 can be aligned with the locking hole 23 at the appropriate height to reset and relock the spring pin 24. A connector 25 is also provided at the lower end of the fixed rod 21 to enhance the stability of the connection between the fixed rod 21 and the telescopic rod 22. The design between the fixed rod 21 and the telescopic rod 22 allows the user to adjust the height of the crutch based on individual usage. Whether indoors or outdoors, the user can easily adjust the height of the crutch to suit different ground conditions and usage needs.

[0039] The design of the fixed rod 21 and the telescopic rod 22 not only provides structural stability and safety, but also meets the diverse needs of users in terms of functionality. Through reasonable material selection and humanized design, the crutch can provide users with a better user experience and adapt to different life scenarios and personal needs.
