Description

Technical Field

[0001] This utility model relates to the field of cane handle technology, specifically to a cane handle with a cushioning air cushion. Background Technology

[0002] Currently, most cane handles with cushioning air pads on the market utilize an air pad structure to provide shock absorption, but their manufacturing process has significant flaws. After injection molding, the parting line of traditional air pads is usually directly exposed around the air pad, severely impacting the product's aesthetics and making it appear rough and cheap. Furthermore, the air pad is often glued to the base and top cover; however, due to the protruding parting line and mismatched edge structures, the glue adhesion area is insufficient, resulting in low bond strength. This easily leads to problems such as glue layer cracking and air pad bursting during long-term use or testing, failing to meet durability testing standards (such as repeated impact and torque tests), seriously affecting product reliability and user experience. Utility Model Content

[0003] To address the problem of weak adhesion of the air cushion in existing cane handles, this invention provides a cane handle with a cushioning air cushion. The specific technical solution of this invention is as follows: A cane handle with a cushioning air cushion includes a base and a top cover, and an air cushion disposed between the base and the top cover. The air cushion is fixed to the base and the top cover respectively by adhesive. The lower end of the base is provided with a mounting head for cooperating with the cane handle. The top edge of the base is curved upward to cover the bottom of the air cushion. The top cover covers the top of the air cushion. The bottom edge of the top cover is provided with a receiving groove for receiving the parting line of the top of the air cushion.

[0004] Furthermore, the top of the air cushion is provided with a first placement groove, and the bottom of the upper cover is provided with a first support column that cooperates with the placement groove.

[0005] Furthermore, the bottom of the air cushion is provided with a second placement groove, which is located directly below the first placement groove, and the upper part of the base is provided with a second support column that cooperates with the second placement groove.

[0006] Furthermore, the top of the cover is provided with grooves on both sides, and anti-slip protrusions are provided in the grooves.

[0007] Furthermore, the anti-slip protrusions are boomerang-shaped and arranged in the grooves.

[0008] Furthermore, the bottom of the base is provided with a wavy protrusion, which is located next to the mounting head.

[0009] Furthermore, the material of the top cover is PU material.

[0010] Furthermore, the air cushion is made of TPU material.

[0020] like Figures 1 to 5As shown, this utility model relates to a cane handle with a cushioning air cushion, including a base 1 and a top cover 3, and an air cushion 2 disposed between the base 1 and the top cover 3. The air cushion 2 is firmly bonded to the top surface of the base 1 and the bottom surface of the top cover 3 respectively by special adhesive. The lower center of the base 1 is provided with a standard mounting head 4 for installation with the cane bar. The mounting head 4 is usually an internal threaded hole or a quick-connect structure. The top edge of the base 1 is raised upward and outward to form a ring of edging structure 5, which is used to wrap and protect the bottom edge of the air cushion 2. The top cover 3 covers the top of the air cushion 2, and its size matches that of the base 1. The bottom edge of the top cover 3 is provided with a continuous receiving groove 6. The receiving groove 6 is used to accommodate the parting line 7 generated by injection molding on the top of the air cushion 2 during assembly, avoiding direct exposure of the parting line 7 under pressure, while ensuring the flatness of the contact surface between the top cover 3 and the air cushion 2, and increasing the adhesion between the top cover 3 and the air cushion 2.

[0021] In one embodiment, the top surface of the air cushion 2 is provided with a downwardly recessed first placement groove 8, and the bottom of the upper cover 3 is provided with a first support post 9 that cooperates with the placement groove. When the upper cover 3 is closed, the first support post 9 is inserted into the first placement groove 8, which plays a role in positioning and auxiliary support, and improves adhesion. The air cushion 2 is provided with a total of 3 first placement grooves 8 arranged in a straight line or a specific pattern, and the number of first support posts 9 is the same as the number of first placement grooves 8, which is 3 in total.

[0022] In one embodiment, the bottom surface of the air cushion 2 is also provided with an upwardly recessed second placement groove 10, which is located directly below the first placement groove 8, corresponding vertically. The upper surface of the base 1 is provided with a second support column 11 that cooperates with the second placement groove 10. During assembly, the second support column 11 is inserted into the second placement groove 10, further enhancing the overall structural stability and compressive strength. The number of second placement grooves 10 and second support columns 11 is the same as the number of first placement grooves 8, both being three.

[0023] In one embodiment, the top surface of the top cover 3 is provided with inwardly recessed grooves 12 on the left and right sides. The shape of the grooves 12 is adapted to the grip curve of human fingers. Several anti-slip protrusions 13 are provided in the grooves 12 to increase the friction between the palm and the handle and prevent slippage.

[0024] In one embodiment, the anti-slip protrusion 13 is a specific boomerang shape (or V-shape, wing shape), which can provide effective anti-slip resistance in multiple directions. The anti-slip protrusion 13 is arranged in the groove 12 in an array or at regular intervals.

[0025] As one embodiment, the bottom outer surface of the base 1, i.e. the area around the mounting head 4, is provided with a wave-shaped protrusion 14, which can provide additional grip and a comfortable feel when the user holds the base 1.

[0026] As one embodiment, the upper cover 3 is made of PU (polyurethane), which has excellent wear resistance, flexibility and a comfortable feel.

[0027] In one embodiment, the air cushion 2 is made of TPU (thermoplastic polyurethane), which has high elasticity, tear resistance and good impact cushioning performance, and is the core component for realizing the cushioning function.

[0028] In one embodiment, the base 1 is made of ABS (acrylonitrile-butadiene-styrene copolymer), which has the characteristics of high strength, good toughness and impact resistance, ensuring the structural support strength of the base 1.

[0029] The cane handle described in this application significantly improves the appearance quality and bonding reliability of the cane handle by optimizing the structure of the upper cover 3 and the base 1: Ultimate aesthetics, completely concealing flaws: By designing a receiving groove 6 on the bottom edge of the top cover 3, the rough parting line 7 on the top of the air cushion 2 is cleverly wrapped and hidden within the groove. At the same time, the top edge of the base 1 curves upward, forming a wrap around the bottom edge of the air cushion 2. These two designs ensure that the parting line 7 of the air cushion 2 is completely concealed from any angle, resulting in a stronger overall appearance, making it more refined and beautiful, and completely eliminating the cheap feeling caused by the exposed parting line 7.

[0030] Significantly enhanced bonding strength, eliminating the risk of delamination: The core advantage of this structure lies in its greatly enhanced bonding reliability. The receiving groove 6 and the raised base 1 provide a larger and more stable bonding area and space for adhesive filling. The adhesive is no longer merely applied to the thin wall of the easily cracked parting line 7, but can fully fill the space between the groove and the air cushion 2, forming a strong "embedded" bonding effect. This results in a qualitative improvement in bonding strength.

[0031] Exceeding testing standards and demonstrating exceptional reliability: Due to the increased bonding area and elimination of stress concentration points, the handle of this invention distributes stress more evenly when subjected to external torque and pressure, thus greatly reducing the risk of adhesive layer cracking. This allows the product to easily pass stringent reliability standards such as torque and durability tests, significantly extending its service life and ensuring full safety.

[0032] In summary, this utility model not only improves the aesthetics of the product, but also fundamentally solves the long-standing problem of weak adhesion that has plagued the industry, achieving multiple technical benefits.
