Description

Technical Field

[0001] This utility model relates to the field of bicycle testing technology, specifically a strength testing device for bicycle rim production. Background Technology

[0002] A bicycle, also known as a pedal bike or cyclist, is a small, two-wheeled land vehicle. Bicycles can also be used as an environmentally friendly means of transportation for getting around. The main components of a bicycle include the frame, fork, handlebars, saddle, and fork assembly. The transmission system includes pedals, cranks, chainrings, chain, bottom bracket, and freewheel, which are powered by human pedaling. The running gear of a bicycle generally includes the front and rear wheels, front and rear axle components, spokes, rims, and tires.

[0003] A search revealed a utility model patent with publication number CN211904652U, which discloses a strength testing device for bicycle rim production. The device includes a workbench with support legs fixedly connected to the four corners of its lower surface. Two symmetrically distributed test plates are fixedly connected to the upper surface of the workbench. Slide grooves are formed on adjacent sides of the two test plates, and threaded rods and sliding rods are fixedly connected to the two slide grooves respectively. In use, a drive motor rotates the threaded rods. Since the threaded rods are threadedly connected to the sliders, the sliders drive the top plate to move vertically, thus conducting a strength test on the rim. Several straps are attached to the outer side of the rim, with Velcro female buckles fixedly connected to the inner end faces of the straps. Several matching Velcro male buckles are fixedly connected to the top plate and the sides of the workbench. After the rim is fixed by the straps, a tensile test can be performed on the rim. This device has a simple structure, is easy to operate, and has a wide range of applications.

[0004] However, the above design still has shortcomings. It can only conduct experimental tests on bicycle rims under static conditions. In practical applications, bicycle rims will experience various dynamic loads during riding, including acceleration, braking, turning, and impacts caused by uneven road surfaces. These dynamic loads have a significant impact on the strength and durability of the rims. Therefore, we provide a strength testing device for bicycle rim production to solve the above problems. Utility Model Content

[0007] Each of the positioning frames has two fixing screws installed on its outer surface, and the bottom end of each fixing screw passes through the positioning frame and is fitted with a fixing block.

[0008] The upper surface of the support platform is equipped with a support frame, and the outer surface of the support frame is equipped with an electric telescopic rod B. The output end of the electric telescopic rod B is rotatably equipped with a fixing block A.

[0009] The upper surface of the support frame is equipped with a motor A, the output end of the motor A is equipped with a connecting rod, and the bottom surface of the connecting rod is equipped with a sliding rod.

[0010] The support frame has a groove on its outer surface, the sliding rod is slidably connected to the inside of the groove on its outer surface, and a detection camera is rotatably mounted on the bottom end of the sliding rod.

[0011] Motor B is mounted on the outer surface of the sliding rod, and the output end of motor B passes through the sliding rod and is connected to the outer surface of the detection camera.

[0012] The outer surface of the support platform is equipped with a controller, and the bottom surface of the support platform is equipped with four support legs.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention uses motor B to drive the electric telescopic rod, fixing block B, and rim body to rotate, simulating the real-world usage state of the rim body. This helps to more accurately evaluate the rim body's performance in actual riding.
