Abstract
Description
Technical Field
[0001] This utility model relates to the field of spring preload adjustment technology, and in particular to a front fork spring preload adjustment structure. Background Technology
[0002] The fork spring is made of spring steel and is helical in shape. It is installed in the front fork of bicycles, motorcycles and other vehicles. It has the functions of shock absorption, weight support and performance adjustment. It needs to be inspected and cleaned regularly to ensure that it works properly. It is a key component of the vehicle's front fork system and directly affects the vehicle's riding comfort and safety. The preload adjustment structure of the fork spring allows the rider to adjust the fork performance according to weight, riding style and road conditions to adapt to different needs, improve riding comfort, stability and handling, and extend the life of the fork for the best riding experience.
[0003] Existing fork spring preload adjustment mechanisms often fail to allow for quick adjustments without tools, thus hindering their ability to meet unforeseen adjustment needs. During long-distance riding, sudden changes in road conditions or load require immediate adjustment of the fork spring preload to adapt to the new situation. However, the lack of tools limits the vehicle's adaptability. Furthermore, the process of finding and using tools for adjustment is time-consuming, reducing efficiency. Especially in emergency situations requiring rapid adjustments for safety, the inability to adjust promptly can pose potential dangers. Therefore, this paper proposes a new fork spring preload adjustment mechanism to address these issues. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a front fork spring preload adjustment structure, which aims to improve the problem that the existing technology cannot achieve preload adjustment of the front fork spring.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A fork spring preload adjustment structure includes a main body, a knob rotatably connected inside the main body, a linkage component for linkage of parts fixedly connected inside the knob, a sliding rod rotatably connected inside the main body, and the linkage component including a connecting rod, one end of the connecting rod being fixedly connected to the inside of the knob, and the other end of the connecting rod being fixedly connected to a connecting shaft.
[0007] As a further description of the above technical solution:
[0008] The outer side of the connecting shaft is fixedly connected to the inside of the sliding rod, and the top outer side of the connecting shaft is fixedly connected to the inside of the knob.
[0009] This utility model has the following beneficial effects:
[0010] In this invention, the connecting rod is driven by manually rotating the knob, which in turn drives the connecting shaft, which in turn drives the sliding rod, thus achieving pre-compression of the spring. Through a comprehensive update and optimization of the existing structure, the overall quality is significantly improved. At the design level, meticulous improvements are made to the internal thread structure, and an innovative anti-rotation limit function is added. This measure brings about several outstanding results. Regarding the improved quality, the use of superior materials and advanced processing technology makes the product appearance more refined and delicate, with a comfortable touch, showcasing high-end quality. Whether from a visual or tactile perspective, it provides users with a completely new experience, satisfying their pursuit of high-quality products. Attached Figure Description
[0011] Figure 1 This is a three-dimensional schematic diagram of a front fork spring preload adjustment structure proposed in this utility model.
[0012] Legend:
[0013] 1. Main body; 2. Knob; 3. Connecting shaft; 4. Connecting rod; 5. Sliding rod. Detailed Implementation
[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] Reference Figure 1 This utility model provides an embodiment of a front fork spring preload adjustment structure, comprising a main body 1 made of a robust and durable high-strength alloy material, providing stable support and reliable protection for the entire structure. A knob 2 is rotatably connected inside the main body 1. The knob 2 has an anti-slip textured surface, making operation easier and more convenient, and rotation more precise and reliable. A linkage component for linking parts is fixedly connected inside the knob 2. This linkage component can efficiently transmit power and ensure coordinated operation between various parts.
[0016] The main body 1 has an internal rotating connection to a sliding rod 5. The sliding rod 5 is made of high-quality steel, precision-machined, with a smooth surface and smooth rotation, enabling accurate adjustment of the spring preload. The linkage assembly includes a connecting rod 4, made of high-strength stainless steel, which has good rigidity and corrosion resistance, and can stably transmit torque. One end of the connecting rod 4 is fixedly connected to the inside of the knob 2. This connection method allows the rotation of the knob 2 to be quickly transmitted to the connecting rod 4, achieving rapid response.
[0017] A connecting shaft 3 is fixedly connected to the outer side of the other end of the connecting rod 4. The connecting shaft 3 plays a crucial transmission role, transmitting the movement of the connecting rod 4 to the sliding rod 5. The connecting shaft 3 is made of alloy steel, possessing high strength and wear resistance, and can withstand significant pressure and torque. The outer side of the connecting shaft 3 is fixedly connected to the inside of the sliding rod 5, ensuring a secure connection and accurate transmission. The top outer side of the connecting shaft 3 is fixedly connected to the inside of the knob 2, further enhancing the stability and reliability of the entire structure and making operation smoother.
[0018] Working principle: When the operator needs to adjust the preload of the internal spring, they can manually turn the knob 2 to drive the connecting rod 4. The connecting rod 4 drives the connecting shaft 3, which in turn drives the sliding rod 5. By rotating the sliding rod 5 downwards, the preload of the spring can be adjusted. One side of the connecting rod 4 is fixedly connected to the inside of the knob 2, and the other side is fixedly connected to the inside of the connecting shaft 3. The outer side of the connecting shaft 3 is fixedly connected to the inside of the sliding rod 5, and the sliding rod 5 is rotatably connected to the inside of the main body 1. The lower end of the sliding rod 5 has a thread, which allows it to be rotated downwards while simultaneously locking itself to prevent the spring force from pushing the sliding rod 5 back.
[0019] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
