Description

Technical Field

[0001] This utility model relates to the field of walking wheels, specifically a shock-absorbing wheel. Background Technology

[0002] Authorization notice number CN106820516B discloses a desk rolling case, which allows a desk to be disassembled and stacked into a rolling case, increasing its functionality. It can be used for storage and transportation as a rolling case, and also as a desk, improving its practicality. However, when the case is loaded with many items, the shaking during walking is noticeable. Without shock absorption, the internal components, connections, and handles can easily loosen, affecting the product's durability and causing discomfort to the user. This is a drawback. How to reduce the vibration of the desk rolling case during walking, making it more stable, while also providing stability when used as a desk, is crucial to perfecting the product's functionality and providing a better user experience. Summary of the Invention

[0003] To address the shortcomings of existing products described above, this utility model provides a shock-absorbing wheel that can be used in office desk rolling suitcases or other luggage. It combines shock-absorbing and non-shock-absorbing functions. When the shock-absorbing function is locked, it functions as a non-shock-absorbing wheel. When the office desk rolling suitcase is used as luggage, the shock-absorbing function is activated, reducing vibration and making walking smoother. When used as an office desk, the shock-absorbing function is locked, allowing the desk to be placed firmly and stably on the ground. Even when subjected to pressure or pushing forces, the desk remains stable without vibration, without compromising its stability. This improves the functionality of the office desk rolling suitcase and provides consumers with a better user experience.

[0004] This utility model adopts the following technical solution: a shock-absorbing wheel, including a first wheel bracket, a second wheel bracket, a spring, a running wheel, a snap fastener, a connecting shaft, and a spring positioning component. The upper end of the second wheel bracket is provided with a wheel seat, and the lower end of the first wheel bracket is provided with a running wheel. The first wheel bracket and the second wheel bracket are connected by a connecting shaft. The first wheel bracket can rotate, move downwards, or move upwards around the connecting shaft. A spring fixing part is provided at the upper end of the first wheel bracket, and a spring positioning component is installed in the spring fixing part. A spring is installed in the spring positioning component. A spring fixing position is provided at the lower end of the second wheel bracket, and the upper end of the spring in the spring positioning component can be inserted into the spring fixing position. After the first wheel bracket and the second wheel bracket are connected, the spring is located between the first wheel bracket and the second wheel bracket. When the first wheel bracket is vertically subjected to upward force, the first wheel bracket will move upwards around the connecting shaft and compress the spring. When the spring contracts, its elastic potential energy increases, absorbing the energy of vibration and weakening the vibration. Through the cooperation of the spring and the connecting shaft, the spring connects the first wheel bracket and the second wheel bracket, achieving the function of buffering and shock absorption.

[0005] The upper end of the connecting shaft is provided with threads, and the threaded end of the connecting shaft can engage with the threaded hole at the lower end of the second wheel bracket to be fixed together.

[0006] The wheel seat of the second wheel bracket can be connected and fixed to the bottom of the office desk trolley case or other trolley cases, and the shock-absorbing wheel is installed and fixed at the bottom of the office desk trolley case.

[0007] The spring fixing part of the first wheel bracket is provided with a number of ball bearing positions arranged in a circular array around the connecting shaft, so that balls can be placed in the ball bearing positions. The bottom of the spring positioning member is provided with a ball bearing groove that mates with the ball bearing positions. The spring positioning member can rotate around the ball bearing as a support point. When the first wheel bracket rotates, the resistance transmitted to the spring positioning member is small. Even when the first wheel bracket is subjected to the tension of the spring during the movement of the suitcase, the first wheel bracket can rotate smoothly and move smoothly when turning.

[0008] The ball groove of the spring positioning component is annular, and the upper end of the ball in the ball position is located in the ball groove. The ball of the spring positioning component is a small spherical steel ball or a wear-resistant plastic ball.

[0009] The second wheel bracket is equipped with a rotatable and adjustable snap fastener frame. The lower end of the snap fastener frame has a clavicle-like structure. Symmetrical rotating parts are located on the side of the second wheel bracket and connected to the snap fastener frame. The snap fastener frame can rotate downwards or upwards around the rotating parts as an axis. The rotating part can be a circular pin, and the snap fastener frame has a pin hole that engages with the pin. When the external force rotating the snap fastener frame exceeds the static friction clamping force, the snap fastener frame can rotate around the pin as an axis.

[0010] The first wheel bracket has several locking slots inside its wheels, which engage with the snap fastener frame to lock into place. When the snap fastener frame rotates downwards around the rotating part, the snap fastener frame inserts into the locking slots of the wheels, connecting the first and second wheel brackets together. The spring is then fixed within the first and second wheel brackets, locking the shock absorption function and preventing the wheels from rotating. The wheels are now fixed, and the shock-absorbing wheels are fixed without shock absorption. When the desk is in use, the shock absorption function is locked to prevent the desk from moving under pressure or pushing force, thus affecting its use.

[0011] When the snap fastener of the first wheel bracket rotates upward, the collarbone in the snap fastener can disengage from the locking groove of the wheel. At this time, the spring and the wheel are unlocked. The first wheel bracket and the second wheel bracket have an elastic shock absorption function, and the wheel can rotate. When the office desk trolley case is used as a suitcase, it has a shock absorption function during walking.
