Description
Technical Field
[0001] This utility model relates to the field of bicycle handlebar testing technology, specifically a bicycle handlebar pull-out performance testing device. Background Technology
[0002] Quality testing of bicycle handlebars requires testing the pull-out force of the handlebar grips. Current technology uses a clamp to hold and fix the handlebar tube, and then gradually increases the pulling force to pull the handlebar grip. When the handlebar grip separates from the handlebar tube, the force at the moment of separation is recorded as the pull-out force of the handlebar grip. However, the test results for the pull-out force and the separation stroke after separation are not ideal.
[0003] Currently, bicycle handlebars are typically straight or curved, making it difficult to adjust the design according to the handlebar shape when performing pull-out performance tests. This results in the testing structure being unable to adapt to different handlebar shapes for pull-out testing, and the testing equipment is prone to detaching when clamping the handlebar, affecting the adaptability and practicality of the equipment for pull-out performance testing of workpieces. Therefore, those skilled in the art have provided a bicycle handlebar pull-out performance testing device to solve the problems mentioned in the background art. Utility Model Content

[0028] Furthermore, the clamping component includes a first screw 9 penetrating the inner side of the sliding frame 3, a sliding block 10 located outside the first screw 9 and inside the sliding frame 3, a mounting frame 11 mounted on the top of the sliding block 10, a pad groove 12 laid out at the bottom of the mounting frame 11, and the clamping component also includes a second screw 13 mounted on the top of the mounting frame 11, a driving block 14 mounted at the bottom of the second screw 13, a pressure block 15 mounted at the bottom of the driving block 14, a pressure groove 16 opened at the bottom of the pressure block 15, a limit rod 26 fixedly connected to the top of the driving block 14, the limit rod 26 penetrating the mounting frame 11 and slidably connected to it, the second screw 13 penetrating the mounting frame 11 and screwed to it, the second screw 13 rotatably connected to the pressure block 15 and not disengaged, the first screw 9 penetrating the sliding block 10 and screwed to it, and the sliding block 10 slidably connected to the sliding frame 3.

The pressure groove 16 at the bottom of the pressure block 15 and the pad groove 12 at the bottom of the mounting bracket 11 press and fix the handle sleeve.

At the same time, the indicator needle 5 at one end of the sliding frame 3 slides on the scale 4, and the guide block 24 at the bottom of the sliding frame 3 slides in the guide groove 25. Then, the controller 8 displays the pressure value of the cylinder 6 to judge the handle pull-out performance.
