Description

Technical Field

[0001] This utility model relates to the field of bicycle accessories technology, specifically to a retractable and adjustable length bicycle wheel reflector. Background Technology

[0002] Bicycle reflectors are a key component for improving safety while riding at night, as they reflect light to alert surrounding vehicles and pedestrians to the rider's position.

[0003] Most existing reflectors are fixed-size, one-piece structures that require matching the spoke density of the wheelset during installation (such as the common "4-pair," "6-pair," or "8-pair" wheelsets, meaning the wheelset has 4, 6, or 8 pairs of spokes). If the reflector size does not match the spoke spacing, it can lead to unstable installation or incomplete engagement, affecting reflectivity and riding safety. Furthermore, traditional reflector installation structures are simplistic, typically fixing the reflector to a single spoke only via a central clip, making it prone to loosening due to vibration during riding. Therefore, a reflector structure that can flexibly adapt to different wheelsets, provides stable installation, and is easy to adjust is needed. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a retractable and adjustable length bicycle wheel reflector, which addresses the problems of fixed reflector size, poor adaptability, and insufficient installation stability in the prior art. It enables adaptation to wheel sets with different wire braiding densities such as "4-way", "6-way", and "8-way", while improving installation stability.

[0005] This utility model embodiment is implemented as follows: a retractable and adjustable length bicycle wheel reflector includes: a left main body and a right main body, which are configured to cooperate with each other. A micro glass bead-shaped reflector is fixedly mounted on the left main body; a convex groove is formed on the right side of the left main body, and an elliptical hole A is formed through the convex groove; an outer groove is formed on the left edge of the left main body for engaging the outermost spoke of the wheel assembly; a concave groove is formed on the left side of the right main body that matches the convex groove formed on the left main body, and an elliptical hole B is formed through the concave groove; a snap-fit ​​hole is formed on the right side of the right main body, and a wire snap-fit ​​groove is formed inside the snap-fit ​​hole for engaging the innermost spoke of the wheel assembly; a square snap-fit ​​is configured to cooperate with the elliptical holes A and B for engaging into the elliptical holes A and B to fix the relative positions of the left and right main bodies; a circular snap-fit ​​is configured to cooperate with the snap-fit ​​hole for engaging into the snap-fit ​​hole to prevent the innermost spoke of the wheel assembly from disengaging from the wire snap-fit ​​groove.

[0006] Preferably, the left main body is provided with a square groove, and the square groove is matched with a square protrusion provided on the right main body, and the square protrusion can slide along the square groove.

[0007] Preferably, the left and right main bodies are injection molded from ABS engineering plastic, and the square buckle is made of elastic PP material.

[0008] Beneficial effects: This utility model provides a retractable and adjustable bicycle wheel reflector. Through a nested groove and elliptical hole adjustment structure, the reflector length can be flexibly extended and retracted, adapting to wheelsets with different wire weave densities such as "4-ply," "6-ply," and "8-ply," solving the problems of fixed size and poor versatility of traditional reflectors. The three-point spoke engagement and square buckle double fixation ensure the reflector does not loosen during riding vibrations, improving structural reliability. Furthermore, the length can be adjusted manually by sliding the left and right main bodies without tools, and the elliptical hole positioning design simplifies the operation process, allowing users to quickly complete the installation and adaptation.

Detailed Implementation

[0013] To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following description is provided in conjunction with the appendix. Figure 1-3 The present invention will be further described in detail below with reference to the embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention. Figure 1 , Figure 2 and Figure 3 As shown, a retractable and adjustable length bicycle wheel reflector includes:

[0014] A left main body 1 and a right main body 2 are configured to cooperate with each other. A micro glass bead-shaped reflector 3 is fixedly mounted on the left main body 1. A convex groove 11 is formed on the right side of the left main body 1, and an elliptical hole A12 is formed through the convex groove 11. An outer groove 13 is formed on the left edge of the left main body, which is used to engage the outermost spoke of the wheel assembly. A concave groove 21 is formed on the left side of the right main body 2, which matches the convex groove 11 formed on the left main body, and an elliptical hole is formed through the concave groove 21. B22, a buckle hole 23 is provided on the right side of the right main body 2, and a wire groove 24 is provided inside the buckle hole 23. The wire groove 24 is used to engage the innermost spoke of the wheel assembly; a square buckle 4 is configured to cooperate with the elliptical holes A12 and B22, and is used to engage in the elliptical holes A12 and B22 to fix the relative position of the left main body 1 and the right main body 2; a circular buckle 5 is configured to cooperate with the buckle hole 23, and is used to engage in the buckle hole 23 to prevent the innermost spoke of the wheel assembly from disengaging from the wire groove 24.

[0015] like Figure 1 and Figure 2 As shown, in a preferred embodiment of the present invention, a square groove 6 is provided on the left main body 1, and a square protrusion 7 is provided on the right main body 2. The square protrusion 7 can slide along the square groove 6.

[0016] The convex groove 11 of the left main body 1 and the concave groove 21 of the right main body 2 are nested and connected to form a sliding fit. After the connection, the elliptical hole A12 and the elliptical hole B22 coincide to form a through elliptical hole. By adjusting the relative position of the left main body 1 and the right main body 2, the overall length of the reflector can be changed (the adjustment range covers the wire spacing of the "4" wheel set to the wire spacing of the "8" wheel set). After the left main body 1 and the right main body 1 are connected, the square buckle 4 is inserted into the through elliptical hole formed by the elliptical hole A12 and the elliptical hole B22 to fix the relative position of the left main body 1 and the right main body 2 and prevent them from stretching or loosening.

[0017] The outer slot 13 of the left main body 1 engages the first steel wire of the wheel assembly; the inner side of the combined left main body 1 engages the second steel wire of the wheel assembly; the steel wire slot 24 of the buckle hole 23 of the right main body 2 engages the third steel wire of the wheel assembly. The three-point engagement structure forms a stable triangular support, improving the connection strength between the reflector and the wheel assembly.

[0018] The right main body 2 has a square protrusion 7, and the left main body 1 has a square groove 6. When adjusting the length, the square protrusion 7 can slide along the square groove 6. After sliding to the target position, the square buckle 4 is inserted into the through elliptical hole to achieve the positioning and locking of the left main body 1 and the right main body 2.

[0019] Microglass bead type reflector 3: The core structure of this type of reflector consists of microglass beads (approximately tens of micrometers in diameter) embedded in a high-reflectivity film. The reflection process is as follows: When external light (such as car headlights or streetlights) shines on the reflector, the light first enters the microglass beads and is refracted (changing its direction of propagation); the refracted light then contacts the high-reflectivity film (usually aluminum foil or other high-reflectivity materials) at the bottom of the microglass beads and is reflected; the reflected light is refracted again by the microglass beads and finally exits at an angle nearly parallel to the incident direction, thus "reflecting" the light back to the light source (such as a car driver's eyes), creating a strong reflective effect. The advantage of this design is its wide viewing angle (covering a large range of incident angles), making it suitable for scenarios requiring omnidirectional reflection (such as bicycle frames, wheels, etc.).

[0020] like Figure 1 As shown, in a preferred embodiment of this utility model, the left main body 1 and the right main body 2 are injection molded from ABS engineering plastic, and the square buckle is made of elastic PP material.

[0021] The left main body 1 is injection molded from ABS engineering plastic. The convex groove 11 is 5-8mm wide and 3-5mm deep. The elliptical hole A12 has a major axis of 15-20mm and a minor axis of 5-8mm. The outer slot 13 has a depth of 2-3mm (suitable for common spoke diameters). The right main body 2 has a concave groove 21 that matches the convex groove 11 of the left main body 1. The elliptical hole B22 overlaps with the elliptical hole A12, forming an adjustment range of 25-35mm in total length. The buckle hole 23 has a diameter of 8-10mm, and the wire slot 24 has a width of 2-3mm. The square buckle 4 is made of elastic PP material with a thickness of 1-2mm. After locking, the gap between the buckle and the reflector body is ≤0.5mm, ensuring a secure lock.

[0022] Installation process: According to the wire spacing of the wheel set ("4", "6", or "8"), slide the left main body 1 and the right main body 2 to adjust the total length of the reflector to the appropriate size; insert the outer slot 13 of the left main body 1 into the first spoke, and insert the inner side of the left main body 1 into the second spoke; fasten the square buckle 4 to fix the relative position of the left main body 1 and the right main body 2; insert the wire slot 24 of the buckle hole 23 of the right main body 2 into the third spoke, and at the same time press the round buckle 5 so that its bottom cylindrical protrusion is inserted into the buckle hole 23 to complete the positioning.

[0023] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are similarly included within the protection scope of the present utility model.
